Introduction:. Displaced and shortened clavicle shaft fractures can be treated operatively by intra- or extramedullary fixation. The aim of the study was to compare the effectiveness of these two treatment modalities. Methods:. Forty seven patients with acute displaced and shortened clavicle shaft fractures were randomly assigned to either an intramedullary locked fixation group or an anatomically contoured locked plating group. All patients were operated by the same surgeon and had identical post-operative treatment regimes. The effectiveness of both treatment regimens were assessed based on; incision length, operative time and union rate. Disabilities of the Arm, Shoulder and Hand Score (DASH) and Constant Shoulder Score were assessed one year post-operatively. Results:. Twenty-five patients were included in the plating group and twenty-two in the intramedullary fixation group. No differences between the two groups were found for age, gender, fracture comminution and/or displacement. Incision size was significantly (p<0.0001) smaller in the nailing group (38±9 mm) than in the plating group (118±19 mm). In line with this the operating time was also shorter in the nailing group than in the plating groups (43±8 min and 60±19 min, respectively (p=0.0029)). One year postoperatively a 100% union rate was achieved in both groups. Lower DASH scores (2±5 vs 16±18 (p=0.0071)) and higher Constant Shoulder scores (96±6 vs. 90 ± 18 (p=0.0122)), were found in the nailing group. Conclusion:. Both anatomically contoured locked plating and locked intramedullary fixation resulted in successful treatment of displaced and shortened clavicle shaft fractures. Intramedullary fixation however was associated with shorter operating times and smaller incision sizes. In addition, better DASH and Constant Shoulder scores were found in the nailing group one year post operatively. Based on these finding and the absence of prominent subcutaneous hardware necessitating removal of the nail, the intramedullary device is a good alternative to treat displaced clavicle shaft fractures

Aim: To report the clinical and radiological outcome of intramedullary fixation following corrective femoral diaphyseal derotational osteotomy, particularly in children with cerebral palsy. Methods: We conducted a retrospective study of all femoral diaphyseal derotational osteotomies with Trigen antegrade intramedullary fixation (TAN system, Smith & Nephew) from April 2005 to June 2006. There were 9 patients with 14 affected limbs. The diagnosis was spastic diplegia in 8 of the 9 children, of whom 5 underwent the osteotomy as part of multilevel surgery. Results: The mean age at surgery was 13.7 years (Range 11.2 – 17.3 years). The mean preoperative femoral anteversion was 43.6 degrees (Range 30 – 50 degrees) with the mean internal & external rotation being 61.6 (Range 50 – 70) & 8.3 (Range 0 – 20) degrees respectively. The average follow-up period was 9.5 months (Range 1.5 – 15 months). All patients mobilised with crutches in an average of 5 days (Range 3 – 12 days) and full weight bearing was achieved by 65 days (Range 45 – 150 days). Marked improvement in gait was noted in all children with postoperative mean internal & external rotation being 42.9 & 52.6 degrees respectively. There have been no instances of avascular necrosis or postoperative complications to date. Correction was maintained at the final follow up in all children with good bony union by 8 – 12 weeks. Conclusion: The key to the success of femoral derotational osteotomy for correction of excessive femoral anteversion in children lies in achieving correction and early mobilisation. Intramedullary fixation following diaphyseal derotational osteotomy in children is a safe, effective, cosmetic and reliable procedure with rapid bony union, attributable to biological fixation and early mobilisation. Good early results have been obtained in children with cerebral palsy undergoing this procedure as a part of multilevel corrective surgery

Introduction: Mid-shaft clavicular fractures that are displaced and shortened are often treated surgically. The standard technique in the past has been to use plate fixation. However, in the last five years intramedullary fixation has been popularised. To our knowledge no recent study has compared the outcomes of intramedullary pinning and plating of displaced mid-shaft clavicular fractures. Method: We retrospectively evaluated 40 patients with mid-shaft clavicular fractures. Twenty patients had plate fixation and twenty patients had intramedullary fixation for exactly the same fracture pattern. Each patient filled out a standardised questionnaire particular to clavicular fractures and was assessed using the Shoulder Score Index of the American Shoulder and Elbow Surgeons and the Constant Score. A physical examination was performed and individual radiographs were assessed to determine the state of union. Results: All fractures that were treated with intramedullary pin fixation went on to union within two to three months. There was one nonunion in the plate fixation group requiring revision surgery. The results revealed no significant difference in the functional outcome scores. There were however fewer complications, less scar related paraesthesia, shorter stay in hospital, and earlier mobilization in the group who underwent intramedullary pinning. Conclusions: Our results suggested that both techniques of intramedullary pinning and plating resulted in good long-term functional outcomes for patients with acute mid-shaft clavicular fractures. Intramedullary pinning, however, resulted in fewer short-term complications. From this study the method of fixation for mid-shaft clavicle fractures should be determined by the surgeon’s preference and expertise

We undertook a prospective randomised trial to determine the outcome of locked intramedullary fixation vs. plating of displaced shortened mid-shaft clavicle fractures. The primary outcome measure was the Constant shoulder score, while secondary outcome measures included the Oxford shoulder score, union rate, and complication rates. Thirty-two patients were recruited to the trial; 17 randomised to locked intramedullary fixation and 15 randomised to plating. Mean age was 29.3years (13 to 53 years). Mean follow-up was 12.4 months (5 to 28 months). There was no significant difference in Constant scores (p = 0.365) and no significant difference in Oxford scores (p = 0.686). There was 100% union in both groups. In the intramedullary group, there was one case of soft tissue irritation that settled after the pin was removed, one pin backed out and had to be revised with another pin. There were three superficial wound infections resulting in plate removal and 8 plates (53%) were removed. Locked intramedullary fixation and plating are equally effective in the management of shortened displaced mid-shaft clavicle fractures

The reliability of the radiological assessment of the healing of tibial fractures remains undetermined. We examined the inter- and intraobserver agreement of the healing of such fractures among four orthopaedic trauma surgeons who, on two separate occasions eight weeks apart, independently assessed the radiographs of 30 patients with fractures of the tibial shaft which had been treated by intramedullary fixation. The radiographs were selected from a database to represent fractures at various stages of healing. For each radiograph, the surgeon scored the degree of union, quantified the number of cortices bridged by callus or with a visible fracture line, described the extent and quality of the callus, and provided an overall rating of healing. The interobserver chance-corrected agreement using a quadratically weighted kappa (κ) statistic in which values of 0.61 to 0.80 represented substantial agreement were as follows: radiological union scale (κ = 0.60); number of cortices bridged by callus (κ = 0.75); number of cortices with a visible fracture line (κ = 0.70); the extent of the callus (κ = 0.57); and general impression of fracture healing (κ = 0.67). The intraobserver agreement of the overall impression of healing (κ = 0.89) and the number of cortices bridged by callus (κ = 0.82) or with a visible fracture line (κ = 0.83) was almost perfect. There are no validated scales which allow surgeons to grade fracture healing radiologically. Among those examined, the number of cortices bridged by bone appears to be a reliable, and easily measured radiological variable to assess the healing of fractures after intramedullary fixation

Aims. Custom-made partial pelvis replacements (PPRs) are increasingly used in the reconstruction of large acetabular defects and have mainly been designed using a triflange approach, requiring extensive soft-tissue dissection. The monoflange design, where primary intramedullary fixation within the ilium combined with a monoflange for rotational stability, was anticipated to overcome this obstacle. The aim of this study was to evaluate the design with regard to functional outcome, complications, and acetabular reconstruction. Methods. Between 2014 and 2023, 79 patients with a mean follow-up of 33 months (SD 22; 9 to 103) were included. Functional outcome was measured using the Harris Hip Score and EuroQol five-dimension questionnaire (EQ-5D). PPR revisions were defined as an endpoint, and subgroups were analyzed to determine risk factors. Results. Implantation was possible in all cases with a 2D centre of rotation deviation of 10 mm (SD 5.8; 1 to 29). PPR revision was necessary in eight (10%) patients. HHS increased significantly from 33 to 72 postoperatively, with a mean increase of 39 points (p < 0.001). Postoperative EQ-5D score was 0.7 (SD 0.3; -0.3 to 1). Risk factor analysis showed significant revision rates for septic indications (p ≤ 0.001) as well as femoral defect size (p = 0.001). Conclusion. Since large acetabular defects are being treated surgically more often, custom-made PPR should be integrated as an option in treatment algorithms. Monoflange PPR, with primary iliac fixation, offers a viable treatment option for Paprosky III defects with promising functional results, while requiring less soft-tissue exposure and allowing immediate full weightbearing.

Background: Long bone fractures and intramedullary stabilisation can result in the extravasation of fat and marrow emboli into the venous circulation. The effects of these emboli can become systemic causing neurological features. Aim: To establish the cerebral microembolic load following femoral and tibial diaphyseal fractures treated by intramedullary fixation and to specify any neurological impairment with the application of a series of cognitive tests and a serum marker of neuronal injury. Methods: 20 femoral and tibial fractures treated with intramedullary fixation had intra-operative transcranial doppler ultrasound monitoring of the middle cerebral artery with emboli detection software set to established guidelines. Cognitive testing (day 3), following surgery with an I.Q. assessment (PFSIQ) allowing comparison with age specific normative data. This included: verbal fluency and speed (COWAT – Control Oral Word Association Test); working memory with assessment of immediate and delayed recall; mini-mental state examination; executive function, attention and mental processing speeds (Colour Trails 1& 2). Beta S-100 levels measured pre-operatively, 0, 24 and 48 hours following surgery as a marker of neuronal injury. Statistical Analysis: One sample Wilcoxon signed rank test to compare median of the cognitive scores with age matched normative data. Multiple regression analysis used to correlate embolic load with cognitive function. Results: Mean age (SD) for the group is 32 (5.8). Mean PFSIQ of 52.8%, SD 21.4 [median 59.5, IQ range 28.3, 71.3]. No significant difference detected in cognitive testing compared with normative data. Cerebral microemboli detected in 17 of 20 patients with a count median (range) of 6 (0, 29). The mean pre-operative beta S-100 level was 0.36 micro g/l (normal range 0–0.15). This increased to a peak mean of 0.88 micro g/l immediately following surgery with a poor correlation to cerebral embolic load. Discussion: Detailed clinical testing indicates no significant deterioration in cognitive function following intramedullary stabilisation of these fractures. A variable cerebral micro-embolic load was seen but with no detectable clinical effect. No direct correlation was found between the elevated levels of Beta S-100 seen following surgery and cerebral embolic load. This appears to correlate with previous concerns in the literature regarding the specificity and sensitivity of this established marker of neuronal injury

Purpose. Plating remains the most widely employed method for the fixation of displaced diaphyseal clavicle fractures. The purpose of this study was to assess the efficacy and outcomes of diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood clavicle pin. Methods. We conducted a retrospective analysis of all diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood pin between February 2004 and March 2010. Sixty-eight procedures were carried out on 67 patients. Functional outcome was assessed using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and an overall patient satisfaction questionnaire. Results. There were 52 (77.6%) male and 15 (22.4%) female patients with an average age of 35.8 years. In 35 (51.5%) cases the injury was located on the dominant side. Fractures were classified according to the Edinburgh system with the commonest configuration being the Type 2B1 (47, 69.1%). The indications for fixation were; acute management of displaced fractures (56, 82.4%), delayed union (2, 2.9%), nonunion (8, 11.8%) and malunion (2, 2.9%). The average time to pin removal was 3.7 months and the average follow-up prior to discharge was 6.9 months. Sixty-six (97.1%) fractures united without consequence. Two (2.9%) cases of non-union were treated with repeat fixation using a contoured plate and bone graft. The most common problem encountered postoperatively was discomfort due to subcutaneous pin prominence posteriorly (12, 17.6%) which resolved following removal of the metalwork. The average DASH score was 6.04 (0–60) and 96.4% of patients rated their satisfaction with the procedure as good to excellent. Conclusion. Due to its minimally invasive technique, cosmetically favourable scar, preservation of periosteal tissue, avoidance of stress risers associated with screw removal and good clinical outcomes, the use of this device is the preferred method of treatment for displaced diaphyseal clavicle fractures in our hospital

Aims. The aim of this study was to examine perioperative blood transfusion practice, and associations with clinical outcomes, in a national cohort of hip fracture patients. Methods. A retrospective cohort study was undertaken using linked data from the Scottish Hip Fracture Audit and the Scottish National Blood Transfusion Service between May 2016 and December 2020. All patients aged ≥ 50 years admitted to a Scottish hospital with a hip fracture were included. Assessment of the factors independently associated with red blood cell transfusion (RBCT) during admission was performed, alongside determination of the association between RBCT and hip fracture outcomes. Results. A total of 23,266 individual patient records from 18 hospitals were included. The overall rate of blood transfusion during admission was 28.7% (n = 6,685). There was inter-hospital variation in transfusion rate, ranging from 16.6% to 37.4%. Independent perioperative factors significantly associated with RBCT included older age (90 to 94 years, odds ratio (OR) 3.04 (95% confidence interval (CI) 2.28 to 4.04); p < 0.001), intramedullary fixation (OR 7.15 (95% CI 6.50 to 7.86); p < 0.001), and sliding hip screw constructs (OR 2.34 (95% CI 2.19 to 2.50); p < 0.001). Blood transfusion during admission was significantly associated with higher rates of 30-day mortality (OR 1.35 (95% CI 1.19 to 1.53); p < 0.001) and 60-day mortality (OR 1.54 (95% CI 1.43 to 1.67); p < 0.001), as well as delays to postoperative mobilization, higher likelihood of not returning to their home, and longer length of stay. Conclusion. Blood transfusion after hip fracture was common, although practice varied nationally. RBCT is associated with adverse outcomes, which is most likely a reflection of perioperative anaemia, rather than any causal effect. Use of RBCT does not appear to reverse this effect, highlighting the importance of perioperative blood loss reduction. Cite this article: Bone Joint J 2022;104-B(11):1266–1272

Introduction: The majority of forearm fractures in children can be managed with a plaster cast alone and manipulation under anaesthetic as required. A small number of cases however require surgical intervention. A variety of methods are available but the use of elastic intramedullary nails is becoming the technique of choice. Method: We present a two-centre study assessing the outcome of either Elastic StabJe Intramedullary Nails (ESIN) or Kirschner wires as the method of fracture stabilisation in diaphyseal forearm fractures of the radius and ulna. Results: ESIN group: 24 children underwent ESIN fixation. There were 22 boys and 2 girls, mean age 9.4 years (1.4–15.2 years, p=O.ll). Indications for stabilisation included 21 cases for fracture instability (immediate or delayed,) 2 irreducible fractures and 1 open fracture. 14 children underwent surgery on the day they sustained their fracture. The remainder were operated on an average 6.5 days following injury (1–14 days). In the K wire group: 36 children underwent K-wires fixation with 2.5mrn wires. There were 21 boys and 15 girls, mean age 10.6 years (2.2–15.5 years). Indication for stabilisation included 22 cases for fracture instability , 6 irreducible fractures and 8 open fractures. 32 children underwent surgery on the day they sustained their fracture. The remaining 4 patients were operated on the following day. Conclusions: All fractures united with no resultant subjective disability. The complication rate following K-wires was 16% and that following nail fixation 9%. Loss of forearm rotation was documented in 4 children in the K-wire group and 3 children stabilised with nails. These results confirm an excellent outcome following intramedullary fixation. We have demonstrated no difference in outcome between K-wires and ESIN, although the elastic nails do offer some theoretical advantages

Introduction: Intramedullary fixation is a recognised method of fracture fixation in fifth metacarpal fractures. We describe a new technique for fixation of fractures of the middle three metacarpals. Patients and Methods: We reviewed a single surgeon’s series of 16 male patients (mean age 27.9 years, range 18–46) with 20 displaced transverse midshaft fractures of the 2nd, 3rd and 4th metacarpals treated by antegrade intramedullary Kirschner wiring. Work related and domestic accidents constituted the mode of injury in 8 patients and in the remaining 8 as a result of an assault, fall or road traffic accident. Twelve patients were in employment at the time of injury including four heavy manual labourers. A single pre-bent 1.6 millimetre Kirschner wire was inserted into the medullary canal through a drill hole in the metacarpal base and passed across the reduced fracture into the metacarpal head. The proximal end of the wire remained protruding percutaneously. Following stabilisation of the fracture, early mobilisation was commenced. Results: All of the study group had satisfactory clinical and radiological outcomes. All of the fractures united clinically and radiologically. There was one case of delayed union, with union at 35 weeks. In the remaining patients fracture union had occurred radiologically at an average of 5.4 weeks (range 4–12 weeks). Radiologically there was a mean angular deformity of 4.05° (range 0–11°) in the coronal plane and 0.75° (range 0–9°) in the sagittal plane. Postoperatively 2 patients developed a pin tract infection requiring treatment with antibiotics and early removal of the K-wire. All patients on questioning by telephone questionnaire were satisfied with their resulting hand function and appearance. All patients had returned to normal activities of daily living by 8 weeks. Of those patients in employment all had returned to work by 6 weeks (mean 3.3. weeks). Conclusion: Antegrade intramedullary single K wiring is a useful technique for managing unstable midshaft metacarpal fractures producing excellent clinical and radiological results

Aims

Bone turnover markers (BTMs) follow distinct trends after fractures and limited evidence suggests differential levels in BTMs in patients with delayed healing. The effect of vitamin D, and other factors that influence BTMs and fracture healing, is important to elucidate the use of BTMs as surrogates of fracture healing. We sought to determine whether BTMs can be used as early markers of delayed fracture healing, and the effect of vitamin D on BTM response after fracture.

Aim: To compare two implants, the Gamma Nail and the ACE Trochanteric Nail in the treatment of pertrochanteric femoral fractures. Patients and methods: Sixty patients were randomized on admission to two treatment groups. Thirty patients were treated with the Gamma nail implants , and thirty had intramedullary fixation with ACE Trochanteric NailI . The average age of these patients was 79 years. 22 patients were men and 38 women. 11 fractures were stable and 49 unstable. Patients were followed for 1 year and had a regular clinical and radiological review at 1, 3 and 6 months postoperatively. Operation time, intra-operative blood loss and blood transfusion and complications were recorded. The mobility score was used to assess the preinjury and postoperative mobility status. All the patients were operated within 24 hours after their accident and 39 of them within the first 6 hours. Results: There were no complications during the surgery. All the patients were mobilized the first 24 hours post operatively irrespectively of the fracture’s type, and weight bearing was permitted as tolerated. The mean follow up time was 8 months (range 6 to 12 months). 3 patients were lost at the follow up and 2 died. Union of the fracture was achieved in all 55 patients. There was no statistically significant difference between the two groups with regard to intraoperative blood loss and the duration of the surgery. There was no mechanical failure of the implants despite the early patients mobilization. All the patients achieved mobility status similar to the preoperative at the latest follow up. Conclusions: Based on our study, intramedullary nailing of pertrochanteric hip fractures represents a reliable method of treatment. We did not observe any differences in the two patient groups concerning the operation time, the intraoperative blood loss, the postoperative complications and the patients functional status at the latest follow up

Aims and methods. To compare the mechanical stability of an intramedullary (IM) screw with two crossed interfragmentary compression screws for fixation of the 1st MTPJ in ten pairs of cadaveric feet. One foot underwent fixation with two crossed 4.0-mm cannulated cancellous screws. The contralateral foot was fixed with an IM 1.6-mm Kirschner wire and an IM 6.5-mm partially threaded cancellous lag screw. A plantar-to-dorsal load was applied to the distal end of the proximal phalanx at a rate of 1 mm/sec. Failure was defined as gross actuator displacement of 5 mm. Stiffness was defined as the slope of the force versus deformation curve between 10 and 60 N. Strength was defined as the load at failure. The differences in stiffness and strength parameters between the two fixation techniques were checked for significance (P < 0.05) with a paired t-test. Results. The intramedullary MTP joint fixation was significantly stiffer (18.7 ± 10.1 N/mm) than control group fixation (10.2 ± 6.1 N/mm). Similarly MTP joint fixation in the IM group was stronger (149.2 ± 88.2 N) than that of the control group (100.2 ± 70.8 N), but this was not significant (P = 0.07). Conclusions. The IM technique resulted in a stronger stiffer fixation when compared with the standard crossed lag screw technique

Tip-apex distance (TAD) has long been discussed as a metric for determining risk of failure in fixation of peritrochanteric hip fractures. This study seeks to investigate risk factors including TAD for hospital readmission one year after hip fixation surgery.

A retrospective review of proximal hip fractures treated with single screw intramedullary devices between 2016 and 2020 was performed at a 327 bed regional medical center. Patients included had a postoperative follow-up of at least twelve months or surgery-related complications developing within that time.

44 of the 67 patients in this study met the inclusion criteria with adequate follow-up post-surgery. The average TAD in our study population was 19.57mm and the average one year readmission rate was 15.9%. 3 out of 6 patients (50%) with a TAD > 25mm were readmitted within one year due to surgery-related complications. In contrast, 3 out of 38 patients (7.9%) with a TAD < 25mm were readmitted within one year due to surgery-related complications (p=0.0254). Individual TAD measurements, averaging 22.05mm in patients readmitted within one year of surgery and 19.18mm in patients not readmitted within one year of surgery were not significantly different between the two groups (p=0.2113).

Our data indicate a significant improvement in hospital readmission rates up to one year after hip fixation surgery in patients with a TAD < 25mm with a decrease in readmissions of over 40% (50% vs 7.9%). This result builds upon past investigations by extending the follow-up time to one year after surgery and utilizing hospital readmissions as a metric for surgical success. With the well-documented physical and financial costs of hospital readmission after hip surgery, our study highlights a reduction of TAD < 25mm as an effective method of improving patient outcomes and reducing financial costs to patients and medical institutions.

Introduction

The use of vascularised fibula grafts is an accepted method for reconstructing the distal femur following resection of malignant childhood tumours. Limitations relate to the mismatch of the cross-sectional area of the transplanted fibula graft and thel ocal bone, instability of the construct and union difficulties. We present midterm results of a unique staged technique—an immediate defect reconstruction using a double-barrel vascularised fibula graft set in in A-frame configuration and a subsequent intramedullary femoral lengthening.

Purpose: Many surgical techniques have been described for the treatment of pathological fractures due to aggressive unicameral bone cysts in order to varying rates of success and incomplete healing or recurrence. Many Authors suggested curettage and bone grafting as effective treatment in case of active lesion in children 8 – 12 years old, adjacent to the physis with width of the lesion exceeds that of the adjacent physis and recurrence or persistence. Due to invasive nature of operation this method non is preferred by several Authors : we preferred minimally invasive treatment consisting closed reduction and flexible with titanium rod (Nancy)intramedullary fixation for low operative morbidity whether for the fracture or for the cyst; in case of recurrence of the cyst the closed curettage of the cyst with arthroscopic technique can be applied successful. Methods: Between 2002–2004 40 aggressive unicameral cysts were observed as pathologic fractures in patients between 5–15 years old in these cases there was a significant loss of bone stock. The site of involvement was in 33 patients the metadiaphysis of humerus, in 7 the femur; radiograms reveal expanding lesion in metaphyseal-diaphyseal site with cortex tinned from its inner surface and erosion with infraction with displacement. The parents were informed about contextual presence of two lesions: the fracture and cyst. The proposed internal fixation with Nancy titanium rods heals the first and might heal the second lesion ; in case of failure this method do not exclude another possibility of treatment as arthroscopic curettage. The Nancy flexible intramedullary fixation was performed with retrograde access 3 0 4 mm. diameter. Two nails with “ Eiffel Tower” construction were inserted by two miniportals 1 centimetres far from the physis. Follow up of treated lesion was made with periodic x rays performed every 45 days. Results: In 36 patients after a 2-year period of observation the cyst has completely or incompletely healed but with a sufficient bone stock in the remainder four cases the arthroscopic procedure was performed. Curettage of cystic wall by trimmer blade and multiple miniportals 4,5 millimetres is the best way to treat all the cyst. In all the cases we used the standard optical cannula 30°. Conclusions: In conclusion minimally invasive treatment by Nancy rods and artrhoscopy can be effective because assure high incidence of favourable results by decompression-scaffolding of the lesions, the patient quickly recover natural life and school attendance

400 patients with a trochanteric hip fracture were randomised to fixation with either a 220mm long Targon PF (proximal femoral) nail or a Sliding Hip Screw. All surgery was undertaken or supervised by one surgeon. All patients were followed up for a minimum of one year by a blinded observer. The mean age was 82 years (range 27 to 104 years), 20% were male. Mean length of surgery was slightly increased for the nail (44 versus 49 minutes, p=0.002). Fluoroscopic screening time was increased in the nail group (0.3 versus 0.6 minutes, p< 0.0001). Intra-operative complications were more common with the nailing. There was no difference in blood transfusion requirement between groups. Postoperatively there was no difference in the occurrence of medical complications or mortality. Deep wound infection requiring removal of the implant occurred in one case in the SHS group. In addition there were two cases of cut-out, three of plate detachment from the femur and one non-union in the SHS group, requiring secondary surgery. There were only once compilations in the nailed a case of cut-out which required secondary surgery. At follow-up there was no difference in pain scores between groups but there was a tendency to improved mobility in the nailed group (p=0.004). These results suggest that with improved designs and surgical technique, the newer versions of short nails for proximal femoral fractures may not suffer from the complications of the earlier short intramedullary nails. Intramedullary fixation can result in a lower re-operation rate (3.5% versus 0.5%) and improved mobility in comparison to the sliding hip screw

The Sliding Hip Screw (SHS) is currently the treatment of choice for all trochanteric hip fractures. An alternative treatment is the short femoral nail. Earlier designs of these nails were associated with an increased fracture healing complication rate in comparison to the sliding hip screw. The new designs of nails (third generation nails) may however be as good as or even superior to sliding hip screw fixation. We conducted a large randomised trial to compare the Targon Proximal Femoral Nail with the Sliding Hip Screw. Patients with trochanteric hip fractures as per the AO classification (A1–A3) were randomised to either implant. All surgery was supervised by one surgeon. All patients were followed up for a minimum of one year months by a blinded observer. The mean age was 82 years, range 27 to 104 years), 20% were male. Length of surgery was slightly increased for the nail (44 versus 49 minutes, p=0.002). Fluoroscopic screening time was increased in the nail group (0.3 versus 0.6 minutes, p< 0.0001). Intra-operative complications were more common with the nailing. There was no difference in blood transfusion requirement between groups. Postoperatively there was no difference in the occurrence of medical complications or mortality. Deep wound infection requiring removal of the implant occurred in one case in the SHS group. In addition there were two cases of cut-out, three of plate detachment from the femur and one non-union in the SHS group, requiring secondary surgery. There was only one compilation in the nailed a case of cut-out which required secondary surgery. At follow-up no difference in pain scores but there was a tendency to improved mobility in the nailed group (p=0.004). These results suggest that with improved designs and surgical technique, the newer versions of short nails for proximal femoral fractures may not suffer from the complications of the earlier short intramedullary nails. Intramedullary fixation can result in a lower re-operation rate (3.5% versus 0.5%) and improved mobility in comparison to the sliding hip screw

Introduction and Aims: The ‘Boxer’s fracture’ is a common injury. Often these fractures are treated conservatively with acceptable functional results, leaving the patient with a residual deformity. A minimally invasive technique of treating these fractures was investigated.

Method: Twenty-three consecutive patients with a fractured neck of the fifth metacarpal with a volar angulation exceeding 40 degrees were offered treatment with a prograde intramedullary K-wire. All 23 patients accepted this treatment with informed consent. A 1.6 mm pre-bent K-wire was inserted via the base of the fifth metacarpal in each case. Time to regaining full function, time to union and final functional and radiological outcome were looked at.

Results: All 23 patients went on to full clinical and radiological union within six weeks. In 18 patients the reduction was anatomical with no residual angulation. In five, the residual angulation ranged from five to 15 degrees with an average of eight degrees. Two patients suffered a transient sensory neuropraxia.

Conclusion: The presented technique is a simple, cost-effective and reliable method of treating a ‘Boxer’s fracture’. Although this type of injury can often be treated without surgery, this procedure ensures a rapid return to full function with little or no residual deformity.

Regardless of the method used, open ankle arthrodesis is known to have a high rate of nonunion, reported to range from 4% to 25%. Salvage of failed ankle fusion is thus a relatively common procedure. Further, in cases of bone loss after distal tibial trauma, necrosis of the talus, Charcot joints and severe deformities of the ankle, there are known to be increased incidences of delayed union and nonunion.

Since 1997, 25 salvage ankle arthrodesis procedures have been performed, using a retrograde interlocking intramedullary nail as fixation. In this paper we discuss the indications, surgical techniques and results.

At a mean of nine weeks postoperatively, union was achieved in all cases. Complications included one case of late sepsis, which presented four years after surgery. During the operation one tibial fracture occurred. One distal screw backed out. The fixation was removed from three patients, one for late sepsis, one for septic nonunion, and the patient in whom the tibia fractured.

Lower limb fractures in children are common. These fractures can be managed in a variety of ways, and the method chosen depends on a number of factors including:

Age of the child.

Site of fracture.

Whether the fracture is open or closed.

Associated injuries.

Surgeon’s expertise and experience.

Parental wishes.

Femur: Immediate or early hip spica gives good results withminimal shortening particularly in the younger child. Flexible IM nails have been widely reported and give good results. It is important to appreciate the mechanics of how the nails function to stabilise the bone and to recognise that pre-bending the nails is a vital step in the operation. As surgeons become more confident in using the nails, the range of indications can be extended to include proximal or distal fractures, comminuted, open and pathological fractures.

Tibia: Skeletal stabilisation of open tibial fractures can be provided by application of an external fixator. The use of flexible IM nails in the tibia is more controversial. Introduction of these nails into the proximal tibia can be difficult and even with pre-bending of the wires, additional cast protection may be required.

We present two cases of metastatic lung cancer which occurred at the site of a previously united tibial fracture. Both patients were treated with a locked intramedullary nail. The patients presented with metastases at the site of their initial fracture approximately 16 and 13 months after injury respectively.

We discuss this unusual presentation and review the relevant literature. We are unaware of any previous reports of a metastatic tumour occurring at the site of an orthopaedic implant used to stabilise a non-pathological fracture. These cases demonstrate the similar clinical presentation of infection and malignancy: a diagnosis which should always be considered in such patients.

From May 2002 to April 2003, a prospective, non-randomised, blinded study was undertaken in 30 patients with fractures of the femur and tibia, all treated with unreamed intramedullary (AO) nail fixation. There were 17 (57%) femoral shaft fractures and 13 (43%) tibial shaft fractures. Most of the patients (23) had been injured in road findings accidents, 17 of them pedestrian. No patient had any known co-morbidities.

Fourteen patients (47%) were HIV positive, nine with femoral fractures and five with tibial fractures. Three patients with compound femoral fractures were HIV positive, two HIV negative. The mean age of HIV-positive patients with femoral shaft fractures, two men and seven women, was 33 years (18 to 48). The mean age of the eight HIV-negative men with femoral shaft fractures was 28 years. Five tibial fractures were compound, three in HIV-positive patients and two in HIV-negative patients. The mean age of HIV-positive patients with tibial fractures, three men and two women, was 31 years (18 to 56). The mean age of the HIV-negative patients, seven men and one woman, was 28 years. All the fractures were Gustillo-Anderson grade- II.

At 12 weeks, 29 fractures had united. In one HIV-positive patient with a compound tibial fracture there were no radiological signs of union at 12 weeks, but after bone grafting the fracture united uneventfully. An HIV-positive patient, who had sustained a gunshot femur injury, developed deep wound infection four months after fixation. In all other patients, the wounds healed uneventfully. In asymptomatic HIV-positive patients, wound healing and fracture union rates are comparable with those of HIV-negative patients.

Introduction

Debate still exists as to the optimum method of fixation for subtrochanteric femoral fractures. Meta-analysis of studies comparing cephalocondylic nails with extramedullary implants for extracapsular hip fractures have suggested that further investigation is required in this area. We present the outcome of the largest series to date of subtrochanteric fractures treated by both methods and with a minimum of one year follow-up.

A retrospective study was done on the outcome of supracondylar femoral fractures treated with retrograde or supracondylar intramedullary nails.

Between January 1998 and December 2000, 69 patients were treated with Russell Taylor nails, 30 at Kalafong Hospital and 39 at Pretoria Academic Hospital. Injuries had resulted from motor vehicle accidents in 27 patients, from falls in 32 and from gunshots in 10. There were 13 open fractures and 14 patients had multiple injuries, including three head injuries and two vascular injuries. Using the AO classification, 40 fractures were graded type A and 29 type C. The mean age of the 18 female and 51 males was 45 years (17 to 90). Senior registrars performed the surgery. In all cases, the knee was opened for the procedure. Four patients died from their injuries.

The mean time to union was 13 weeks. Four patients had poor range of motion. Complications included two cases of superficial sepsis and three of deep sepsis. There were two cases of delayed union and three of fixation failure. In one patient the fixation impinged on the patella.

We find this a good way of treating supracondylar femoral fractures.

Revision knee prostheses are often augmented with intramedullary stems to provide stability following bone loss. However, there are concerns with the use of such stems, including loosening caused by strain-shielding, end-of-stem pain, and removal of healthy bone surrounding the medullary canal. Extracortical fixation plates may present an alternative. The aim of the study was to quantitatively evaluate and compare strain-shielding in the tibia following implantation of a knee replacement component augmented with either a conventional intramedullary stem (design1), or extracortical plates (design2) on the medial and lateral surfaces.

Eight composite synthetic tibiae were implanted with one of the two designs, painted with a speckle pattern, loaded in axial compression (peak 2.5 kN) using a materials test machine, and imaged with a 5-megapixel digital image correlation (DIC) system throughout loading. Bone loss was simulated in all models by removing a volume of metaphyseal bone. For four tibiae, the tibial tray was augmented with a cemented stem (∼150 mm). The others were augmented by extracortical plates (maximum 90 mm long) along the medial and lateral surfaces (Fig. 1). Strains were computed using an ARAMIS 5M software system between loaded and unloaded states in the longitudinal direction, for the medial, posterior and lateral surfaces of the tibiae. Strains were checked locally by use of strain gauge rosettes at three levels on medial, lateral and posterior aspects.

The bone strains measured on the posterior surfaces were reported in three regions; proximal (0–70 mm, where the medial extracortical plate lies), middle (70–130 mm, the stem is present but not the extracortical plates), and distal (130–200 mm, beyond the stem). Mean longitudinal strains for both implant types were comparable in the distal region, and were greater than in the other regions (Fig 2). The mean strains differed considerably in the middle region: 565–715 μstrain with stemmed components 1050–1155 μstrain with plated components. Strains followed a similar pattern in the proximal region, particularly very close (20 mm) to the tibial tray component, where the stemmed component bones (775 ± 160 μstrain) displayed less surface strain than the plated component bones (1210 ± 180 μstrain).

Strain-shielding was observed for both designs. The side plates were shorter than the intramedullary rods, so the region of the bone distal to the plates was not strain-shielded, while the same region was strain-shielded when a stemmed component was implanted. It was also shown that in the region of bone just distal of the tibial tray component, design1 shielded the bone from strain 56% more on average than design2. From these results, it can be speculated that the use of extracortical plate rather than intramedullary stems may lead to improved long-term results of revision TKA, assuming the plates and screws provide adequate stability. The extramedullary fixation system preserves more bone than IM fixation, and has the advantage of allowing use of primary TKA components, cemented over the subframe. Similar components have been developed for the femur.

Aims of study

To assess and compare the functional, radiological and cosmetic results as well as patient satisfaction in patients treated with the IMN Device Vs Volar Locking Plate

Purpose of Study: To evaluate the results of our first consecutive cases using Fixion nail for treatment of femoral shaft fractures.

Materials and Methods: Thirty consecutive patients treated at our department with the expandable Fixion nail for femoral fractures were evaluated in a prospective study. Demographic, preoperative, operative and follow-up data was collected from admission and out-patients files. The pre- and post-operative X-rays were evaluated by two senior authors to determine fracture classification (AO/ASIF-CCF), union and healing. This data was inserted into excel file for statistics and evaluation.

Results: The average age was 36 years. Fourteen fractures were due to MVA, 10-falls, 2-crush injuries, 2-non-unions, 1-pathological and one from gunshot wound. Six fractures were open. Twenty eight were middle shaft fractures and two were distal. Three primary nail diameters were used 8.5mm, 10mm and 12mm.

All fractures healed at an average time of 9.2 weeks (5–26) and for the open fractures 19 (12–26) weeks. Hardware was removed in 8 cases with no complications. In two cases re-operation was needed. In one early case the nail was fractured and replaced. In the second case the bone was circlaged due to fragmentation around the fracture site and a bigger nail was inserted few days later (wrong smaller nail was inserted previously).

Conclusions: This preliminary clinical study demonstrates our experience treating femoral fractures with Fixion nail. We find this nail to be simple for use and with satisfactory healing and alignment results.

Methods of treatment of femoral fractures still remain controversial in adolescent age when the patients are too young for adult-type stabilization. This study examines the possibilities for improving the mechanical parameters of the bone-nail interface in flexible intramedullary nailing.

Mathematical models, which simulate different fractures, have been created by using the finite elements method. The stabilizing construction with two 4,00 mm Ender nails was performed in two versions:

standard divergent “C” configuration (3 points of pressure);

Each version has been tested towards the deforming forces – bending in frontal and sagital plane; torsion and axial loading. Strength coefficient of the nails has been calculated as well as the stiffness of the configuration. The comparative analysis of the results found out that under the angular and torsional forces the mechanical parameters of the two types of configurations are equivalent. However, under axial loading, the divergent “S” configuration shows definitely better mechanical characteristics. The strength coefficient is 30% higher and the stiffness of the configuration is twice as strong. The specific intramedullary cohesion enables more considerable resistance towards the transverse displacement in telescoping of the fragments.

Proceeding from the presented data, it could be considered that the divergent “S” configuration creates much more sufficient length control. Its implementation in axial unstable femoral fractures could enable an earlier mobilization, respectively – an earlier weight-bearing loading.

The purpose of our study was to compare the mechanical nature of nails with different cross-sections in order to optimise the elasticity-stability ratio. There is no doubt that elastic intramedullary osteosynthesis is a successful choice for treating femoral shaft fractures in children. However, misalignment is a potential problem connected with stability of the fixation.

The mechanics of two types of nails with the same type of surface, but with different kind of cross sections – a circle (Ender) and an ellipse – was examined using the “finite elements” method.

The standard configuration of the two nails was put under four kinds of deforming forces: bending in the frontal plane and the sagital plane, torsion, and axial compression. Strength coefficient and stiffness were calculated in each particular situation.

In respect to angular stability (frontal plane) and axial compression, the mechanical characteristics of the two types of nails are similar. The stability of the elliptical nail is higher in bending in the sagital plane and in torsion. The elliptical implant has better intramedullary cohesion because the large half-axis is perpendicular to the sagital plane.

Nails with an elliptical cross section provide the opportunity for redistribution of stiffness. As a result, better mechanical properties are achieved. The elliptical cross section assures better intramedullary cohesion.

Objective: To evaluate and present our experience using the expandable nail system for the treatment of tibial shaft fractures.

Design: Retrospective study.

Setting: Level 1 Trauma Center – University teaching hospital.

Methods: Fifty-nine consecutive patients treated by this nail system for tibia fracture, fifty-four were acute fractures and five non-unions that were not included in the study. Two nail diameters were used, 8.5mm and 10mm. Operation, hospitalization and healing times, reaming versus non-reaming, isolated versus multiple injuries and re-operations were recorded and analyzed statistically.

Results All fractures healed in an average time of 72 days. The average healing times for patients treated with an 8.5 mm and 10 mm nail were 77.2 days and 63.4 days respectively. Average operative time was 103 minutes if reamed and 56 minutes if unreamed. Average healing times were 65.4 if reamed and 79.5 days if unreamed. Hardware was removed in 6 patients, and one patient underwent exchange nailing due to a delayed union. Operative time was shorter in the motor-vehicle group, 74 minutes in comparison to 80 and 84 minutes for the fall and pedestrian group.

Conclusion: The expandable nail offers the theoretical advantages of improved load sharing and rotational control without the need for interlocking screws. This study demonstrates satisfactory healing and alignment for the treatment of tibial shaft fractures using this device.

Background. This is a continued assessment of the effectiveness of a locked intramedullary device in the treatment of acute clavicle shaft fractures. Results of patients treated thus far were assessed, including patients reported on previously. Description of methods. Patients admitted with midshaft clavicle fractures were assessed to determine whether operative fixation of the fracture was required. Indications for surgery were midshaft clavicle fractures with 100% displacement; more than 1.5 cm of shortening, presence of a displaced butterfly segment, bilateral clavicle fractures, ipsilateral displaced glenoid neck fractures, skin and neurovascular compromise. Patients that matched the criteria for surgery were treated operatively with an intramedullary locked device by the author. Post-operatively, patients were kept in a shoulder immobilizer for a period of 6 weeks. Patients were invited to attend a scheduled follow-up visit where the data was collected that comprised the review. All patients were assessed by the surgeon, a radiologist, a physiotherapist and an occupational therapist. Scar size and quality, Dash score, Constant Shoulder score, complications and the radiological picture were assessed. Summary of results. 50 patients (52 clavicle fractures – 2 patients sustained bilateral fractures), 28 males and 22 females with a mean age of 30 attended the schedule data collection visit and were included in the study. 48 clavicles achieved complete union with the remaining 4 fractures progressing normally to union at 10 and 12 weeks post surgery. No additional complications than those reported on previously were encountered. Conclusion. Locked intramedullary fixation of clavicle shaft fractures that match the criteria for operative fixation continues to give good results. No non-unions were found and a high level of patient satisfaction was achieved. The operative technique continues to be refined leading to less fixation related complications. MULTIPLE DISCLOSURES

Objectives

The radiographic union score for tibial (RUST) fractures was developed by Whelan et al to assess the healing of tibial fractures following intramedullary nailing. In the current study, the repeatability and reliability of the RUST score was evaluated in an independent centre (a) using the original description, (b) after further interpretation of the description of the score, and (c) with the immediate post-operative radiograph available for comparison.

Conservative treatment of the ‘boxer’s fracture’ gives acceptable functional results but often leaves the patient with a residual deformity.

Using a prograde intramedullary K-wire, we treated 23 consecutive patients with a fractured neck of the fifth metacarpal. Volar angulation exceeded 40°. A 1.6-mm pre-bent K-wire was inserted via the base of the fifth metacarpal in each case. Time to regaining full function, time to union and final functional and radiological outcome were recorded.

All 23 patients went on to full clinical and radiological union within six weeks. In 18 patients, the reduction was anatomical with no residual angulation. In five the residual angulation ranged from 5° to 15°, with a mean of 8°. There was a transient sensory neuropraxia in two patients.

This minimally invasive technique is a simple, cost-effective and reliable method of treating a ‘boxer’s fracture’ and ensures a rapid return to full function with little or no residual deformity.

Purpose of study:

To assess the effectiveness of a novel locked intra-medullary device in the treatment of acute clavicle shaft fractures.

We investigated the effect of the location and the number of distal screws in the efficiency of an intramedullary nail implementing the finite element method (FEM).

The left proximal femur of a 93-year old man was scanned and two series of full 3D models were developed. The first series, consisting of five models, concerned the use of a single distal screw inserted in five different distal locations. The second series, consisting of four models, concerned the use of four different pairs of distal screws. Each model was analyzed with the (FEM) twice, first considering that the femur is fractured and then considering that the femur is healed.

For nails with a single distal screw, stresses around the nail hole were reduced with proximal placement of the distal screw but the area around the nail hole where the lag screw is inserted is stressed more. Furthermore, for nails with a pair of distal screws, placing the pair of distal screws at a specific location is most beneficial for the mechanical behavior of the femur/nail assembly.

The distal area of the nail generally gets less stressed when a pair of distal screws is introduced, while the presence of two distal screws far away from each other results in lower proximal femoral head displacements. The stress field at the area of fracture is not influenced significantly by the presence of a single distal screw or a pair of distal screws.

Aims. Due to their radiolucency and favourable mechanical properties, carbon fibre nails may be a preferable alternative to titanium nails for oncology patients. We aim to compare the surgical characteristics and short-term results of patients who underwent intramedullary fixation with either a titanium or carbon fibre nail for pathological long-bone fracture. Methods. This single tertiary-institutional, retrospectively matched case-control study included 72 patients who underwent prophylactic or therapeutic fixation for pathological fracture of the humerus, femur, or tibia with either a titanium (control group, n = 36) or carbon fibre (case group, n = 36) intramedullary nail between 2016 to 2020. Patients were excluded if intramedullary fixation was combined with any other surgical procedure/fixation method. Outcomes included operating time, blood loss, fluoroscopic time, and complications. Fisher’s exact test and Mann-Whitney U test were used for categorical and continuous outcomes, respectively. Results. Patients receiving carbon nails as compared to those receiving titanium nails had higher blood loss (median 150 ml (interquartile range (IQR) 100 to 250) vs 100 ml (IQR 50 to 150); p = 0.042) and longer fluoroscopic time (median 150 seconds (IQR 114 to 182) vs 94 seconds (IQR 58 to 124); p = 0.001). Implant complications occurred in seven patients (19%) in the titanium group versus one patient (3%) in the carbon fibre group (p = 0.055). There were no notable differences between groups with regard to operating time, surgical wound infection, or survival. Conclusion. This pilot study demonstrates a non-inferior surgical and short-term clinical profile supporting further consideration of carbon fibre nails for pathological fracture fixation in orthopaedic oncology patients. Given enhanced accommodation of imaging methods important for oncological surveillance and radiation therapy planning, as well as high tolerances to fatigue stress, carbon fibre implants possess important oncological advantages over titanium implants that merit further prospective investigation.

Introduction. The management of fracture-related infection has undergone radical progress following the development of international guidelines. However, there is limited consideration to the realities of healthcare in low-resource environments due to a lack of available evidence in the literature from these settings. Initial antimicrobial suppression to support fracture union is frequently used in low- and middle-income countries despite the lack of published clinical evidence to support its practice. This study aimed to evaluate the outcomes following initial antimicrobial suppression to support fracture union in the management of fracture-related infection. Materials & Methods. A retrospective review of consecutive patients treated with initial antimicrobial suppression to support fracture healing followed by definitive eradication surgery to manage fracture-related infections following intramedullary fixation was performed. Indications for this approach were; a soft tissue envelope not requiring reconstructive surgery, radiographic evidence of stable fixation with adequate alignment, and progression towards fracture union. Results. This approach was associated with successful treatment in 51/55 (93%) patients. Fracture union was achieved in 52/55 (95%) patients with antimicrobial suppression alone. Remission of infection was achieved in 54/55 (98%) patients following definitive infection eradication surgery. Following antibiotic suppression, 6/46 (13%) pathogens isolated from intra-operative samples demonstrated multi-drug resistance. Conclusions. Initial antimicrobial suppression to support fracture healing followed by definitive infection eradication surgery was associated with successful treatment in 93% of patients. The likelihood of remission of infection increases when eradication surgery is performed in a healed bone. This approach was not associated with an increased risk of developing multi-drug-resistant infections compared to contemporary bone infection cohorts in the published literature

The burden of metastatic disease presenting with axial skeleton lesions is exponentially rising predominantly due to advances in oncological therapies. A large proportion is these lesions are located in the proximal femora, which given its unique biomechanical architecture is problematic. These patients are frequently comorbid and require prompt and concise decision making regarding their orthopaedic care in line with recent British Orthopaedic Association guidelines. We present data detailing the outcomes for patients with proximal femoral metastatic disease referred and treated over a three year period in an Regional Cancer Centre. We retrospectively reviewed a prospectively maintained database of all patients referred for discussion at MDT with axial skeletal metastatic disease. From this we isolated patients with femoral disease. Demographic data along with primary tumour and metastatic disease site were assessed. Treatment regimens were analysed and compared. Finally predicted and actual mortality data was collated. 331 patients were referred over the analysed time period, of which 99 had femoral disease. 66% of patients were managed conservatively with serial monitoring while 34% underwent operative treatment. 65% of those received an intramedullary fixation while 35% had arthroplasty performed. There was a 51:49 split male to female with Prostate, Lung and Breast being the predominant primary tumours. Concurrent spinal metastatic disease was noted in 62% of patients while visceral mets were seen in 37%. Mortality rate was 65% with an average prognosis of 388 days (1.06years) while average mortality was noted within 291 days (0.8 years). Proximal femoral metastatic disease accounts for a large volume of the overall mets burden. There is an overall tendency towards conservative management and of those requiring surgery IM nailing was the treatment of choice. The data would indicate that outcomes for these patients are guarded and on average worse than those predicted

Background. Clavicle development occurs before the age of 9 in females and 12 in males. Children below the age of 10 with displaced midshaft clavicle fractures recover well with conservative management. However adolescents are more demanding of function and satisfaction following clavicle fractures and may benefit from operative management. Study aims: 1) Perform a systematic review of the current evidence supporting intramedullary fixation of adolescent clavicle fractures. 2) Review current management in a major trauma center (MTC) with a view to assess feasibility for a randomised controlled trial (RCT). Methods. The MEDLINE, EMBASE and AMED databases were searched in October 2014 to identify all English language studies evaluating intramedullary fixation in children aged 10–18 years using MeSH terms. Data was extracted using a standardised data collection sheet and studies were critically appraised by aid of the PRISMA checklist. All patients aged 9–15 attending an MTC receiving clavicle radiographs in 2014 were retrospectively reviewed for type of fracture, management and outcome. Results. Literature search identified 54 articles. After application of exclusion criteria 3 studies were selected for final review. 47 adolescent patients received intramedullary clavicle fixation from a prospective and two retrospective case series. 61 adolescents presented to our unit with a clavicle fracture in 2014, 2 were lost to follow-up, 54 were managed non-operatively, 3 received titanium-elastic nailing, 1 plate osteosynthesis and 1 bone suture. 0 and 19 patients reported a palpable lump, mean time to pain resolution was 4 and 6 weeks and time to full range of motion was 4 and 5 weeks following operative and conservative management respectively. All patients reached radiographic union. Conclusion. Current evidence supporting intramedullary fixation of clavicle fractures in adolescents is poor. There remains clinical equipoise on the best management of these patients, however they are predominantly treated conservatively. A future multi-center RCT may be feasible. Level of Evidence. 1

Objectives. The PROximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial has recently demonstrated that surgery is non-superior to non-operative treatment in the management of displaced proximal humeral fractures. The objective of this study was to assess current surgical practice in the context of the PROFHER trial in terms of patient demographics, injury characteristics and the nature of the surgical treatment. Methods. A total of ten consecutive patients undergoing surgery for the treatment of a proximal humeral fracture from each of 11 United Kingdom hospitals were retrospectively identified over a 15 month period between January 2014 and March 2015. Data gathered for the 110 patients included patient demographics, injury characteristics, mode of surgical fixation, the grade of operating surgeon and the cost of the surgical implants. Results. A majority of the patients were female (66%, 73 of 110). The mean patient age was 62 years (range 18 to 89). A majority of patients met the inclusion criteria for the PROFHER trial (75%, 83 of 110). Plate fixation was the most common mode of surgery (68%, 75 patients), followed by intramedullary fixation (12%, 13 patients), reverse shoulder arthroplasty (10%, 11 patients) and hemiarthroplasty (7%, eight patients). The consultant was either the primary operating surgeon or supervising the operating surgeon in a large majority of cases (91%, 100 patients). Implant costs for plate fixation were significantly less than both hemiarthroplasty (p < 0.05) and reverse shoulder arthroplasty (p < 0.0001). Implant costs for intramedullary fixation were significantly less than plate fixation (p < 0.01), hemiarthroplasty (p < 0.0001) and reverse shoulder arthroplasty (p < 0.0001). Conclusions. Our study has shown that the majority of a representative sample of patients currently undergoing surgical treatment for a proximal humeral fracture in these United Kingdom centres met the inclusion criteria for the PROFHER trial and that a proportion of these patients may, therefore, have been effectively managed non-operatively.

Background. Fractures of the femoral neck occurring outside the capsule of the hip joint are assumed to have an intact blood supply and hence their conventional management is by fixation rather than arthroplasty. The dynamic hip screw and its variants have been used over many years to fix such fractures but have inherent vulnerabilities; they require an intact lateral femoral cortex, confer a relatively long moment arm to the redistribution of body weight and may cause a stress riser due to the plate with which they are fixed to the femur. Intramedullary devices for fixation of proximal femoral fractures have a shorter moment arm, can be distally locked with reduced perforation of the femoral cortex and are believed to be inherently more stable. For these reasons, a number of surgeons believe them to be superior to the DHS for all extracapsular fractures and their use is now widespread. In this study, we present the usage trends of both devices in extracapsular fractures over the last five years and set these results in the context of patient demographics. Methods. Our departmental electronic patient management system was used to identify all patients undergoing surgery coded as either DHS or its variants or intramedullary fixation of hip fracture. The patients’ age, sex and American Society of Anaesthesiologists grading were recorded. Comparison between groups was made using appropriate tests in SPSS. Results. Our unit has seen a steady move towards the use of intramedullary fixation of extracapsular fractures over five years, from 28.2% to 45.2% of operations, without a change in demographics of the population or a change in surgical outcomes at the most basic level. Conclusion. The move towards intramedullary fixation without evidence of improved outcomes, given the significantly higher cost, requires urgent research. Level of Evidence. IV

Introduction. While knee arthrodesis is a salvage option for recalcitrant total knee arthroplasty (TKA) periprosthetic joint infection (PJI) it is used relatively uncommonly and contemporary data are limited. We sought to determine the reliability, durability and safety of knee arthrodesis as the definitive treatment for complex, persistently infected TKA in a modern series of patients. Methods. We retrospectively identified 41 knees treated from 2002–2016 with a deliberate, two-stage knee arthrodesis protocol (TKA resection, high-dose antibiotic spacer, targeted IV antibiotics and followed by subsequent knee arthrodesis) in patients with complex TKA PJI. Mean age was 64 years & mean BMI was 39 kg/m. 2. Mean follow-up was 4 years. The extensor mechanism was deficient in 66% of knees, and flap coverage was required in 34% of knees. The majority of patients were host grade B (56%) or C (29%), and extremity grade of 3 (71%). Twenty-nine percent had poly-microbial infections, and 49% had multi-drug resistant organisms. Fixation included intramedullary nail (61%), external fixator (24%), and dual plating (15%). Results. Two patients (5%) required amputation for persistently infected non-unions; therefore, limb salvage was accomplished in 95% of patients. After initial treatment, there were non-unions in 24% and persistent infection in 17%. Non-union was significantly correlated with persistent infection, with 50% of non-unions having persistent infection compared with just 6% of united knees (p=0.006). External fixation was a significant risk factor for non-union (70%) compared to intramedullary fixation (8%; p=0.005). Overall, twenty-seven complications occurred in 20 patients and 31% required reoperation other than external fixator removal. Intramedullary fixation led to a 90% rate of both infection control and radiographic union. Conclusion. Two-stage knee arthrodesis using a deliberate protocol (resection, high-dose abx spacer, targeted IV abx, and subsequent arthrodesis) ultimately achieved successful limb salvage in 95% of patients with complex infected TKA. One or more complications occurred in nearly half the patients and reoperation was required for 1-in-3. That substantial risk of complications is not surprising as this large contemporary series included complex, worst-case infected TKA in which: 2/3 had disrupted extensor mechanism, 1/3 required flap coverage, and the majority had poly-microbial or multi-drug resistant organisms. Summary. For contemporary patients with very complex, infected TKA a two-stage knee arthrodesis was reliable in achieving limb salvage (95%) at the cost of a high initial complication and reoperation rate.

Aims. Little is known about the effect of haemorrhagic shock and resuscitation on fracture healing. This study used a rabbit model with a femoral osteotomy and fixation to examine this relationship. Materials and Methods. A total of 18 male New Zealand white rabbits underwent femoral osteotomy with intramedullary fixation with ‘shock’ (n = 9) and control (n = 9) groups. Shock was induced in the study group by removal of 35% of the total blood volume 45 minutes before resuscitation with blood and crystalloid. Fracture healing was monitored for eight weeks using serum markers of healing and radiographs. Results. Four animals were excluded due to postoperative complications. The serum concentration of osteocalcin was significantly elevated in the shock group postoperatively (p < 0.0001). There were otherwise no differences with regard to serum markers of bone healing. The callus index was consistently increased in the shock group on anteroposterior (p = 0.0069) and lateral (p = 0.0165) radiographs from three weeks postoperatively. The control group showed an earlier decrease of callus index. Radiographic scores were significantly greater in the control group (p = 0.0025). Conclusion. In a rabbit femoral osteotomy model with intramedullary fixation, haemorrhagic shock and resuscitation produced larger callus but with evidence of delayed remodelling.

Aims. The aim of this study was to investigate whether clinical and radiological outcomes after intramedullary nailing of displaced fractures of the fifth metacarpal neck using a single thick Kirschner wire (K-wire) are noninferior to those of technically more demanding fixation with two thinner dual wires. Patients and Methods. This was a multicentre, parallel group, randomized controlled noninferiority trial conducted at 12 tertiary trauma centres in Germany. A total of 290 patients with acute displaced fractures of the fifth metacarpal neck were randomized to either intramedullary single-wire (n = 146) or dual-wire fixation (n = 144). The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire six months after surgery, with a third of the minimal clinically important difference (MCID) used as the noninferiority threshold. Secondary outcomes were pain, health-related quality of life (EuroQol five-dimensional questionnaire (EQ-5D)), radiological measures, functional deficits, and complications. Results. Overall, 151/290 of patients (52%) completed the six months of follow-up, leaving 83 patients in the single-wire group and 68 patients in the dual-wire group. In the modified intention-to-treat analysis set, mean DASH scores six months after surgery were 3.8 (. sd. 7.0) and 4.4 (. sd. 9.4), respectively. With multiple imputation (n = 288), mean DASH scores were estimated at 6.3 (. sd. 8.7) and 7.0 (. sd. 10.0). Upper (1 - 2α)) confidence limits consistently remained below the noninferiority margin of 3.0 points in the DASH instrument. While there was a statistically nonsignificant trend towards a higher rate of shortening and rotational malalignment in the single wire group, no statistically significant differences were observed across groups in any secondary outcome measure. Conclusion. A single thick K-wire is sufficient for intramedullary fixation of acute displaced subcapital fractures of the fifth metacarpal neck. The less technically demanding single-wire technique produces noninferior clinical and radiological outcomes compared with the dual-wire approach.

Introduction and Objective. Hip fractures represent one of the most challenging injuries in orthopaedic practice due to the associated morbidity, mortality and the financial burden they impose on the health care systems. By many still considered as the gold standard in the management of intertrochanteric fractures, the Dynamic Hip Screw utilizes controlled collapse during weight bearing to stabilize the fracture. Despite being a highly successful device, mechanical failure rate is not uncommon. The most accepted intraoperative indicator for lag screw failure is the tip apex distance (TAD), yet lateral femoral wall thickness (LWT) is another evolving parameter for detecting the potential for lateral wall fracture with subsequent medialization and implant failure. The aim of this study is to determine the mean and cut off levels for LWT that warrant lateral wall fracture and the implications of that on implant failure, revision rates and implant choice. Materials and Methods. This prospective cohort study included 42 patients with a mean age of 70.43y with intertrochanteric hip fractures treated with DHS fixation by the same consultant surgeon from April 2019 to December 2019. The study sample was calculated based on a confidence level of 90% and margin of error of 5%. Fracture types included in the study are 31A1 and 31A2 based on the AO/OTA classification system. LWT was assessed in all patients preoperatively using Surgimap (Nemaris, NY, USA) software. Patients were divided into two groups according to the post-operative integrity of the lateral femoral wall, where group (A) sustained a lateral femoral wall fracture intraoperatively or within 12 months after the index procedure, while in group (B) the lateral femoral wall remained intact. All patients were regularly followed up radiologically and clinically per the Harris Hip Score (HHS) for a period of 12 months. Results. At 12 months five patients (12%) suffered a postoperative lateral wall fracture, while in 37 patients (88%) the lateral femoral wall remained intact. The mean preoperative LWT of patients with a postoperative lateral wall fracture was 18.04 mm (SD ± 1.58) compared to 26.22mm (SD ± 5.93) in the group without a lateral wall fracture. All patients with post-operative lateral femoral wall fracture belong to 31A2 group, while 78.4% of the patients that did not develop post-operative lateral femoral wall fracture belong to 31A1 group. Eighty percent of patients in group (A) experienced shortening, collapse, shaft medialization and varus deformity. The mean Harris hip score of group (A) was 39.60 at 3 months and 65.67 at 6 months postoperatively, while that of group (B) was 80.75 and 90.65 at 3 and 6 months respectively, denoting a statistically significant difference (P<0.001). Treatment failure meriting a revision surgery was 40 % in group (A) and 8% in group (B) denoting a statistically significant difference (p<0.001). The cut-off point of LWT below which there is a high chance of post-operative lateral wall fracture when fixed with DHS is 19.6mm. This was shown on the receiver operating curve (ROC) by plotting the sensitivity against the 100 % specificity with a set 95% confidence interval 0.721 – 0.954. When lateral wall thickness was at 19.6 mm, the sensitivity was 100% and specificity was 81.8%. The area under the curve (AUC) was 0.838, which was statistically significant (P = 0.015). Conclusions. Preoperative measurement of LWT in elderly patients with intertrochanteric hip fractures is decisive. The cut off point for postoperative lateral wall fracture according to our study is 19.6 mm; hence, intramedullary fixation has to be considered in this situation

Purpose. Intramedullary fixation of clavicle fractures requires an adequate medullary canal to accommodate the fixation device used. This computer tomography anatomical study of the clavicle and its medullary canal describes its general anatomy and provides the incidence of anatomical variations of the medullary canal that complicates intramedullary fixation of midshaft fractures. Methods. Four hundred and eighteen clavicles in 209 patients were examined using computer tomography imaging. The length and curvatures of the clavicles were measured as well as the height and width of the clavicle and its canal at various pre-determined points. The start and end of the medullary canal from the sternal and acromial ends of the clavicle were determined. The data was grouped according to age, gender and lateralization. Results. The average length of the clavicle was 151.15mm with the average sternal and acromial curvature being 146° and 133° respectively. The medullary canal starts on average 6.59mm from the sternal end and ends 19.56mm from the acromial end with the average height and width of the canal at the middle third being 5.61mm and 6.63mm respectively. Conclusion. The medullary canal of the clavicle is large enough to accommodate commonly used intramedullary devices in the majority of cases. The medullary canal extends far enough medially and laterally to ensure that an intramedullary device can be passed far enough medially and laterally past the fracture site to ensure stable fixation in most middle third clavicle fractures. An alternative surgical option should be available in theatre when treating females as the medullary canal is too small to pass an intramedullary device past the fracture site on rare occasions. Fractures located within 40mm of the lateral or medial ends of the clavicle should not be treated by intramedullary fixation as adequate stability is unlikely to be achieved. MULTIPLE DISCLOSURES

Introduction: Most of the bone metastases have origin in breast, lung, prostate, thyroid and kidney neoplasms. The commonest locations are the axial skeleton and the proximal region of the long bones, being the femur the most affected one. The main objectives of the surgical treatment are a quick functional recuperation and immediate pain relief. Objectives: The aim of this work was to define a strategy for the surgical treatment of the bone methastasis located in the femur. Material: The study includes 94 patients with femoral methastasis (100 metastasis) surgicaly treated in the last 10 years in our department. Methods: Retrospective descriptive study based on medical records evaluation. Results: The proximal third of the femur was involved in 80 % of the cases. Pathological fracture was identified in 72 cases and impending fracture in 28. Half of the primitive neoplasms was originated in the breast. It was identified as solitary metastatic lesion only in 33 % of the situations. The mean patient survival time was 9,2 months. They were treated with a cemented calcar-replacing prosthesis in 40 patients, 10 patients submited to conventional arthroplasty and 36 with intramedullary fixation (usually a cephalomedullary nail). The remainder 14 were treated with other surgical techniques. Discussion: The surgery is indicated in case of painful lytic injury or unresponsive to radiotherapy, pathological or impending fracture. The surgical technique depends on the location and size of the lesion and if it is a solitary or multiple bone lesion, choosing between arthroplasties, of preference with long femoral stem, and intramedullary fixation. As we have performed a retrospective study, a functional rigorous evaluation was not possible. Conclusion: The treatment of metastatic femoral disease is not performed with the intention of cure but to improve significantly the patient’s life quality. The proximal third of the femur is the most reached place. Breast cancer was responsible for around 50 % of the cases. In 50% of the patients the surgical option was an arthroplasty and techniques of femoral nailing were performed in 36%. The cemented replacement prosthesis is used in proximal large injuries with periarticular involvement: The intramedullary fixation is reserved for situations in which the femoral head and neck are not involved. The length of patient survival must exceed the predictable surgical recovery period

The “keel” is the relatively short part of the undersurface of the tibial component that extends into the medullary canal. Most knee replacement systems have the capacity to attach modular stem extensions for enhanced intra-medullary fixation for revision. Diaphyseal length, large diameter stems may also guide positioning of trial components and are ideal for accurate surgical technique, even if fully cemented stems are eventually implanted. Smaller diameter non-modular stem extensions may be used for fully cemented fixation. They do not however guide component position very accurately and do not make sense for uncemented fixation. Revision surgery is different from primary surgery and enhanced fixation with some type of intramedullary fixation is highly appropriate, especially if constrained devices might be required. Options for enhanced intramedullary fixation are: 1. Fully cemented metaphyseal or shorter stems; 2. Diaphyseal engaging press fit stems; and 3. Very short fully cemented stems with trabecular metal cone fixation. Metaphyseal length press fit stems do not provide reliable fixation in revision TKA. Revision with primary components or constrained components without any stem extension is not advised

Introduction and Aims: A retrospective review of the medical records and radiographs of patients treated with operative fixation of two-part proximal humerus fractures was undertaken to compare the results of different modes of fixation. Comparison was made between ORIF with a blade plate, percutaneous Kirschner wire fixation, and intramedullary nail fixation utilising a Polarus nail. Method: Thirty-six patients were treated with intramedullary fixation, 11 with blade plate fixation and 10 with percutaneous fixation, utilising Kirschner wires. Union rates were 34/36 (94%) for the Polarus nail, 9/10 (90%) for K-wire fixation and 9/11 (82%) for blade plate fixation. Time to union averaged 12.4 weeks for the Polarus nail, 11 weeks for K-wire fixation and 21 weeks for blade plate fixation. Average active shoulder range of motion in forward flexion/abduction were 125/118 degrees for intramedullary nail, 132/132 degrees for the blade plate and 112/111 degrees for patients treated with K-wire fixation. Results: The major discrepancy in comparison of the different modes of fixation was in the complication rate. Ten complications occurred in the group treated with intramedullary fixation. These included one non-union, one painless fibrous non-union and back out of the proximal interlocking screw in eight patients, five of which required screw removal. Seven of 11 patients treated with blade plate fixation experienced complications, including two non-unions, two malunions, two with functionally limiting heterotopic ossification, one arthrofibrosis and one with persistent pain. The complications associated with percutaneous Kirschner wire fixation included one non-union, two malunions, four developed functionally limiting heterotopic ossification, five incidences of early pin removal secondary to pin migration, one arthrofibrosis requiring surgical intervention and one infection requiring surgical irrigation and debridement. Conclusion: Results comparable in all groups. Fewer complications seen with intramedullary fixation. Majority of complications with Polarus nail related to backing out of proximal interlocking screw. Modification of implant to include end cap, which locks the proximal screw seems to eliminate complication. Results indicate that intramedullary nail fixation is superior to blade plate fixation or pecutaneous Kirschner wire fixation for two-part proximal humerus fractures

Purpose of Study. To see if the addition of a locking plate to FD rod fixation of osteogenesis imperfecta confers extra strength and allows earlier mobilisation. Introduction. Osteogenesis imperfecta is a heterogeneous group of disorders with congenital osseous fragility. The goal of surgery is to minimise the incidence of fracture and correct deformity. The concept of multilevel osteotomies and intramedullary fixation with a non-extendable nail was popularised by Sofield and Millar in 1959. The Bailey Dubow telescoping nail was introduced in 1963. The Fassier-Duval (FD) telescoping nail is a more recent design inserted via smaller incisions, in conjunction with percutaneous osteotomies. However there are still problems. Often the medullary canal may be too narrow to harbour a nail of adequate size for the body. Furthermore they do not give significant rotational control, which is compounded by the elasticity of the soft tissues. Methods. We treated two patients with Osteogenesis imperfecta with supplementary unicortical locked plating in addition to intramedullary fixation with FD rods. Results. The patients both underwent femoral fixation. Both had deformity and previous femoral stress fractures treated non operatively. One patient, aged 24, was non ambulant pre-operatively. She was allowed to transfer without a brace immediately post operatively. The other patient, aged 64 years and ambulant indoors, initially had additional fixation with a non- locking semitubular plate that went onto fail, therefore had revision fixation with a locking plate. She was asked to bear weight as tolerated in a brace immediately post-op. Conclusion. Classically, plates and screws have been avoided in Osteogenesis imperfecta due to the predisposition to fracture at the ends of the plate. We have found that the extra fixation enables extra strength where the nail size is small, and helps control rotation in the post-operative period, allowing earlier mobility

Atypical femoral fractures (AFFs) are reported in patients taking bisphosphonates (BPs). This study aims to describe demographics, potential risk factors and outcome of fixation in AFFs. Forty-three patients with AFF were identified retrospectivity from all identified patients with subtrochanteric or diaphyseal fractures within NHS Grampian between 2008–2018. Patients were identified via hospital coding and electronic search of patients undergoing femoral fixation. AFFs were diagnosed by the 2014 American Society of Mineral and Bone Research diagnostic criteria by electronic patient record review by two investigators. Within this cohort, the incidence of AFF was 8.25% with male to female ratio of 10:1 and a mean of presentation age 73.3 years. 27.9% of AFFs occurred in the diaphysis. 22% of AFFs were bilateral. Mean follow-up was 11.5 months. 87.5% of patients had documented prodromal symptoms. 35% had proven radiological changes before fracture. All patients identified were on BPs. Duration of BPs before fracture was 5 months- 13.2 years (mean 6.3 years). Concurrent use of BPs with steroid and proton pump inhibitors was seen in 58.5%. All patients had intramedullary fixation with 8 (18.6%) requiring revision for non-union. For those that united radiologically it took on average 304 days (220–513). BPs were only stopped in 45% of patients after fixation. AFFs in this cohort appear to be associated with BP use, female sex, clinical and radiological prodrome. AFF remain a difficult clinical problem with a high revision rate. Further work is required to identify the temporal relationships and to raise awareness to improve surveillance/management

Objectives. Intramedullary fixation is considered the most stable treatment for pertrochanteric fractures of the proximal femur and cut-out is one of the most frequent mechanical complications. In order to determine the role of clinical variables and radiological parameters in predicting the risk of this complication, we analysed the data pertaining to a group of patients recruited over the course of six years. Methods. A total of 571 patients were included in this study, which analysed the incidence of cut-out in relation to several clinical variables: age; gender; the AO Foundation and Orthopaedic Trauma Association classification system (AO/OTA); type of nail; cervical-diaphyseal angle; surgical wait times; anti-osteoporotic medication; complete post-operative weight bearing; and radiological parameters (namely the lag-screw position with respect to the femoral head, the Cleveland system, the tip-apex distance (TAD), and the calcar-referenced tip-apex distance (CalTAD)). Results. The incidence of cut-out across the sample was 5.6%, with a higher incidence in female patients. A significantly higher risk of this complication was correlated with lag-screw tip positioning in the upper part of the femoral head in the anteroposterior radiological view, posterior in the latero-lateral radiological view, and in the Cleveland peripheral zones. The tip-apex distance and the calcar-referenced tip-apex distance were found to be highly significant predictors of the risk of cut-out at cut-offs of 30.7 mm and 37.3 mm, respectively, but the former appeared more reliable than the latter in predicting the occurrence of this complication. Conclusion. The tip-apex distance remains the most accurate predictor of cut-out, which is significantly greater above a cut-off of 30.7 mm. Cite this article: G. Caruso, M. Bonomo, G. Valpiani, G.

We are presenting a prospective study of 25 patients with clavicle fracture treated with Rockwood Intramedullary pin fixation. Operative management is required for open fractures, neurovascular injury or compromise, displaced fractures with impending skin compromise and displaced middle third fractures with 20mm or more shortening. Plate osteosynthesis or intramedullary fixation devices are used for operative management. Patients and Methods: 25 patients with clavicle fractures underwent fixation of clavicle fractures with threaded intramedullary Rockwood pin. The indications for internal fixation were persistent wide separation of fracture with interposition of soft tissue in 12, symptomatic non-union in 3, associated multiple injuries in 3,one of them had a floating shoulder, impending open fracture with tented skin in 4 and associated acromioclavicular joint injury in 3 and one of whom had bilateral fracture clavicle.. All patients underwent open reduction through an incision centred over the fracture site along the Langer line. Intramedullary pin was inserted in a retrograde manner. Autologous bone grafting from iliac crest was done in all patients with nonunion. Radiographic and functional assessment conducted using DASH scores. Results: There were 21 male and 4 female patients with a mean age of 34 yrs (range 17 to 64 yrs). Mean follow up was 12 months (range 5 months to 30 months). Radiographic union occurred in all patients within 4 months. In our study the commonest indication for Rockwood pin fixation was displaced middle third clavicle fracture followed by impending open fractures. Commonest complication was skin irritation at the distal end of the pin with formation of a tender bursa occurring in 9 patients, 3 of whom had skin breakdown. Fracture union occurred in all these patients with no further intervention and wounds healed completely after removal of the pin. One patient developed non-union and was later treated with ORIF with DCP and bone-graft. There were no deep infections, pin breakage or migration or re-fractures after pin removal. At the time of last follow up the average DASH score was 25 with a range of 18 to 52. Conclusion: Open reduction and intramedullary fixation of clavicle fractures with Rockwood pin is a safe and effective method of treatment when surgical fixation of displaced or non-union of middle third clavicle fracture is indicated. This technique has an advantage of minimal soft tissue dissection, compression at the fracture site, less risk of migration and ease of removal, along with early return to daily and sports activities

High complication rates and technical difficulties of intramedullary fixation in children with osteogenesis imperfecta have prompted the modification of existing rod systems. The Sheffield telescoping intramedullary rod system was introduced to reduce the complications. It has a T-piece which is permanently fixed to prevent its separation and is expanded to reduce the migration. This study analyses the outcome of this rod system over a 12-year period in two specialist centres. Sixty rods were inserted in the lower limbs of 19 children with osteogenesis imperfecta. All children had multiple fractures of the bones before rod insertion. 39 rods were inserted into the femur, of which 3 were exchange and 4 revision procedures. 21 rods were inserted in the tibia. Eight children had intramedullary rodding of all the four lower limb long bones. The outcome was measured in terms of mobility status, incidence of refractures and rod-related complications. Our series demonstrates that there is significant reduction in refractures and improvement in the mobility status in children with osteogenesis imperfecta following intramedullary fixation. The frequent complication of T-piece separation and the need for reoperation has been overcome with the Sheffield modification of rod design. But the extracortical and metaphyseal migration of the rod continues to be a problem and further improvement in the design is desirable

Background. Endoprosthetic reconstruction is an established method of treatment for primary bone tumours in children. Traditionally these were implanted with cemented intramedullary fixation. Hydroxyapatite collars at the shoulder of the implant are now standard on all extremity endoprostheses, but older cases were implanted without collars. Uncemented intramedullary fixation with hydroxyapatite collars has also been used in an attempt to reduce the incidence of problems such as aseptic loosening. Currently there are various indications that dictate which method is used. Aims. To establish long term survivorship of cemented versus uncemented endoprosthesis in paediatric patients with primary bone tumours. Methods. This was a retrospective study of 441 endoprostheses implanted in 367 consecutive patients aged 18 years or less, between 1973 and 2005. This included the use of case notes, hospital databases and a radiological review. Information obtained included patient demographics, indications for surgery, anatomical distribution and type of implants, complications and survivorship. Results. Mean age was 13.9 (range 3 - 38). 210 patients were male, 157 were female. There were 364 primaries and 77 revision implants. 161 extendable and 280 definitive prostheses. 282 patients had osteosarcoma, 54 had Ewing's sarcoma and 28 had other diagnoses. Commonest sites included 197 distal femoral replacements, 85 proximal tibial implants and 57 were in the upper limb. Kaplan-Meier survival analysis was used to compare anatomical sites and method of fixation. Upper limb implants had the best long term survival. Failure rates for distal femoral replacements were compared for cemented fixation (21.7% due to aseptic loosening) with cement plus hydroxyapatite collars (3.1%) and uncemented implants with hydroxyapatite collars (6.2%). Conclusions. In the distal femur cemented fixation with hydroxyapatite collars gave the best survivorship in definitive primary prostheses. Uncemented fixation with hydroxyapatite collars gave the best survivorship in extendable prostheses. Cemented fixation without hydroxyapatite gave the worst survivorship

High complication rates and technical difficulties of intramedullary fixation in children with osteogenesis imperfecta has prompted the modification of existing rod systems. The Sheffield telescoping intramedullary road has T-piece which is permanently fixed and is expanded to reduce metaphyseal migration. This study analyses the outcome of this rod system over an 11 year period in two tertiary referral hospitals. 60 rods were inserted in the lower limbs of 19 children with osteogenesis imperfecta. All children had multiple fractures of the bones before rod insertion. 39 rods were inserted into femur, of which 3 were exchange and 4 revision procedures. 21 rods were inserted into tibia. Eight children had intramedullary rodding of both femur and tibia bilaterally. The outcome was measured in terms of incidence of refractures, mobility status, functional improvement and rod related complications. Our series demonstrates that there is significant reduction in refractures and improvement in the functional status of children with osteogenesis imperfecta following intramedullary fixation. The frequent complication of T-piece separation and the need for re-operation has been overcome with Sheffield modification of rod design. But the incidence of the rod, particularly at the proximal end of femur remains high and further improvement in the design is desirable

We present five case studies of a new technique for the treatment of distal femur fractures after total knee arthroplasty. This type of fracture is rare, but when it occurs can present a dilemma as to the correct treatment. If the prosthesis is loose, the logical treatment is revision surgery with the use of long stem stabilisation. If the prostheses are firmly fixed, the best method of treatment is difficult to determine. Intramedullary fixation is a well-known modality, but proper fixation distal to the fracture can be problematic in very distal fractures. We performed intramedullary fixation of these fractures, using standard retrograde condylar locking nails inserted through the notch of the femoral prostheses. The problem of distal fixation was solved by fixating the nail to the femoral prostheses with a plate that fitted into the notch of the pros-theses and was securely fixed to the nail with a custom-made screw. This not only gave alignment stability but also aided in compression of the fracture. A locking screw distal to the fracture line was inserted in some patients to aid fixation. but could not be placed in others owing to the distal position of the fracture. Autograft was used in most cases to aid fracture healing. Postoperatively the leg was immobilised in a cast for six weeks. This method of fixation of the nail to the prostheses has not been described in the literature to date. We believe that this technique offers a new modality in treating these complex fractures, providing adequate fixation, alignment and compression stability

Purpose: We present 10 cases of long bone fractures in children (femur, tibia, forearm) that were treated with internal fixation (flexible intramedullary rods). Material and Methods: The patients were 10 children (9 boys and 1 girl), 6 to 15 years of age (mean 10.4 years) suffering of 6 femoral, 3 forearm and 1 tibial fracture, treated with flexible intramedullary rods. The femoral fractures healed between 3 to 4.5 months (mean, 14.7 weeks), the tibial frtacture in 3 months (12.8 weeks) and the forearm fractures in between 1 to 2.2 months (mean 7.6 weeks). Removal of the rods was performed 7.1 to 10 months (mean 39 weeks). Results: The advantages of intramedullary fixation of long bone fractures in children, with flexible rods are: The earlier mobilization of the patient and return to his usual daily activities, the shorter period of hospitalization, the anatomic reduction of the fracture in comparison with conservative treatment (traction-cast) and external fixation and the smaller amount of complications than external fixation ( delayed union, refracture, etc.). Conclusion: In conclusion intramedullary fixation with flexible rods has excellent results under the following conditions: the appropriate fracture (diaphyseal transverse or oblique femoral and tibial fractures and unstable fractures of the forearm) and the correct surgical technique while inserting the rods

Many tumors metastasise to bone, therefore, pathologic fracture and impending pathologic fractures are common reasons for orthopedic consultation. Having effective treatment strategies is important to avoid complications, and relieve pain and preserve function. Thorough pre-operative evaluation is recommended for medical optimization and to ensure that the lesion is in fact a metastasis and not a primary bone malignancy. For impending fractures, various scoring systems have been proposed to determine the risk of fracture, and therefore the need for prophylactic stabilisation. Lower score lesions can often be treated with radiation, while more problematic lesions may require internal fixation. Intramedullary fixation is generally preferred due to favorable biomechanics. Arthroplasty may be required for lesions with massive bony destruction where internal fixation attempts are likely to fail. Radiation may also be useful postoperatively to minimise construct failure due to tumor progression

Traditionally midshaft clavicle fractures have been treated conservatively. It is recognized that displaced and shortened fractures may be better treated operatively. In particular, patients with greater than 20 mm of shortening and 100 percent displacement have a symptomatic non union rate of 30 percent. The standard technique used previously has been via plate fixation with LC-DCP or DCP. However in the last 5 years intramedullary fixation has been popularized. “Rockwood intramedulary clavicular pin” remedies the past treatment issues including poor blood supply, painful prominent hardware and stress raiser related to removal of metal work. Aim: The aim of this study was to assess the functional outcome following intramedullary fixation of clavicle using Rockwood pin. Method: We retrospectively evaluated 17 patients with displaced and shortened mid-shaft clavicular fractures who underwent intramedullary pinning using Rock-wood pins. Each patient was assessed using the ASES, Constant and SF36 scoring system. A physical examination was performed and individual radiographs were assessed to determine union. Results: The mean age of the patients was 28 (range 15–56). All patients went into union within 2 to 4 months. They had a shorter stay in hospital, earlier mobilization and no scar related paraesthesia. The average ASES score 98.2 (range 92–100) and constant 95.3 (range 89–100). Summary: Displaced and shortened mid clavicular fractures require operative fixation. Plates and screws on the clavicle requires significant soft tissue stripping leading to compromised blood supply to the bone and multiple bi-cortical screws act as stress raisers. Previous intra-medullary devices presented with the problem of pin migration. Rockwood pins are designed with a differential pitch which leads to compression at the fracture site and prevent pin migration. From this study we now recommend the use of the Rockwood Pin for the management of displaced mid-shaft clavicle fractures

Flexible intramedullary nailing is gaining popularity as an effective method of treating long-bone fractures in children. We retrospectively reviewed the records and radiographs of 56 unstable fractures of the tibia in 54 children treated between March 1997 and May 2005. All were followed up for at least two months after the removal of the nails. Of the 56 tibial fractures, 13 were open. There were no nonunions. The mean time to clinical and radiological union was ten weeks. Complications included residual angulation of the tibia, leg-length discrepancy, deep infection and failures of fixation. All achieved an excellent functional outcome. We conclude that flexible intramedullary fixation is an easy and effective method of management of both open and closed unstable fractures of the tibia in children

Objectives. Osteosynthesis of anterior pubic ramus fractures using one large-diameter screw can be challenging in terms of both surgical procedure and fixation stability. Small-fragment screws have the advantage of following the pelvic cortex and being more flexible. The aim of the present study was to biomechanically compare retrograde intramedullary fixation of the superior pubic ramus using either one large- or two small-diameter screws. Materials and Methods. A total of 12 human cadaveric hemipelvises were analysed in a matched pair study design. Bone mineral density of the specimens was 68 mgHA/cm. 3. (standard deviation (. sd). 52). The anterior pelvic ring fracture was fixed with either one 7.3 mm cannulated screw (Group 1) or two 3.5 mm pelvic cortex screws (Group 2). Progressively increasing cyclic axial loading was applied through the acetabulum. Relative movements in terms of interfragmentary displacement and gap angle at the fracture site were evaluated by means of optical movement tracking. The Wilcoxon signed-rank test was applied to identify significant differences between the groups. Results. Initial axial construct stiffness was not significantly different between the groups (p = 0.463). Interfragmentary displacement and gap angle at the fracture site were also not statistically significantly different between the groups throughout the evaluated cycles (p ⩾ 0.249). Similarly, cycles to failure were not statistically different between Group 1 (8438, . sd. 6968) and Group 2 (10 213, . sd. 10 334), p = 0.379. Failure mode in both groups was characterised by screw cutting through the cancellous bone. Conclusion. From a biomechanical point of view, pubic ramus stabilisation with either one large or two small fragment screw osteosynthesis is comparable in osteoporotic bone. However, the two-screw fixation technique is less demanding as the smaller screws deflect at the cortical margins. Cite this article: Y. P. Acklin, I. Zderic, S. Grechenig, R. G. Richards, P.

Periprosthetic femoral fractures are increasing in incidence, and typically occur in frail elderly patients. They are similar to pathological fractures in many ways. The aims of treatment are the same, including 'getting it right first time' with a single operation, which allows immediate unrestricted weightbearing, with a low risk of complications, and one that avoids the creation of stress risers locally that may predispose to further peri-implant fracture. The surgical approach to these fractures, the associated soft-tissue handling, and exposure of the fracture are key elements in minimizing the high rate of complications. This annotation describes the approaches to the femur that can be used to facilitate the surgical management of peri- and interprosthetic fractures of the femur at all levels using either modern methods of fixation or revision arthroplasty.

Damage Control techniques involve primary external fracture fixation to reduce the ‘second hit’ of surgery. This study used a large animal (ovine) trauma model to compare pathophysiological responses of primary external femoral fixation and intramedullary stabilisation. Under terminal anaesthesia bilateral femoral fractures and hypovolaemia were produced using a pneumatic ram. 24 sheep were randomised into 4 groups and monitored for 24 hours. Group 1 – Control; Group 2 – Trauma only; Group 3 – Trauma and external fixation; Group 4 – Trauma and reamed intramedullary stabilisation. Outcome measures: pulmonary embolic load (transoesophageal echocardiography); plasma coagulation markers; bronchoalveolar lavage differential cell counts (neutrophils, lymphocytes and macrophages). Total embolic load was significantly higher (p<0.001) in the intramedullary fixation group (median score 42 versus 20). All trauma groups had a significant increase (p < 0.05) in prothrombin time with a fall in antithrombin III and fibrinogen levels. No significant differences occurred between trauma groups with any coagulation or alveolar lavage marker. Intramedullary femoral fracture fixation produced a relatively higher pulmonary embolic load. However, the initial fracture fixation method did not affect any of the changes seen in the measured coagulation or inflammatory markers during the first 24 hours of injury

Aims

The management of mid-shaft clavicle fractures (MSCFs) has evolved over the last three decades. Controversy exists over which specific fracture patterns to treat and when. This review aims to synthesize the literature in order to formulate an appropriate management algorithm for these injuries in both adolescents and adults.

Aims. The fundamental concept of open reduction and internal fixation (ORIF) of ankle fractures has not changed appreciably since the 1960s and, whilst widely used, is associated with complications including wound dehiscence and infection, prominent hardware and failure. Closed reduction and intramedullary fixation (CRIF) using a fibular nail, wires or screws is biomechanically stronger, requires minimal incisions, and has low-profile hardware. We hypothesised that fibular nailing in the elderly would have similar functional outcomes to standard fixation, with a reduced rate of wound and hardware problems. Patients and Methods. A total of 100 patients (25 men, 75 women) over the age of 65 years with unstable ankle fractures were randomised to undergo standard ORIF or fibular nailing (11 men and 39 women in the ORIF group, 14 men and 36 women in the fibular nail group). The mean age was 74 years (65 to 93) and all patients had at least one medical comorbidity. Complications, patient related outcome measures and cost-effectiveness were assessed over 12 months. Results. Significantly fewer wound infections occurred in the fibular nail group (p = 0.002). At one year, there was no evidence of difference in mean functional scores (Olerud and Molander Scores 63; 30 to 85, versus 61; 10 to 35, p = 0.61) or scar satisfaction. The overall cost of treatment in the fibular nail group was £91 less than in the ORIF group despite the higher initial cost of the implant. Conclusion. We conclude that the fibular nail allows accurate reduction and secure fixation of ankle fractures, with a significantly lower rate of soft-tissue complications, and is more cost-effective than ORIF.

Malnutrition is a potentially modifiable risk factor that may contribute to complications following geriatric hip fracture surgery. The purpose of this study was to investigate the association between preoperative hypoalbuminemia, a marker for malnutrition, and complications during the thirty days following surgery for geriatric hip fracture. The American College of Surgeons National Surgical Quality Improvement Program was used to conduct a retrospective cohort study of geriatric patients (>65 years) undergoing surgery for hip fracture. Patients without preoperative serum albumin concentration were excluded. Outcomes were compared between patients with and without hypoalbuminemia (defined as serum albumin concentration <3.5g/dL). All comparisons were adjusted for baseline differences between populations. 17,651 Patients were identified. Of these, 8,272 (46.9%) underwent hemiarthroplasty, 759 (4.3%) total joint arthroplasty, 324 (1.9%) percutaneous fixation, 2,445 (13.9%) plate/screw fixation, and 5,833 (33.1%) intramedullary fixation. The prevalence of hypoalbuminemia was 45.9% (Figure 1). The risk for death was strongly associated with serum albumin concentration, with a linear increase in risk observed as albumin fell below 3.5 g/dL (p<0.001; Figure 2). Following adjustment for all demographic, comorbidity, and procedural characteristics, patients with hypoalbuminemia had higher rates of death (9.94% versus 5.53%, adjusted relative risk [RR]=1.54, p<0.001), pneumonia (5.30% versus 3.77%, adjusted RR=1.20, p=0.012), sepsis (1.19% versus 0.53%, adjusted RR=1.90, p<0.001), and hospital readmission (10.91% versus 9.03%, adjusted RR=1.11, p<0.036; Table 1). The present study suggests that hypoalbuminemia is a powerful independent risk factor for death following surgery for geriatric hip fracture. This association persists over-and-above any associations of death with age, sex, body mass index, and comorbidities. Based on these data, we propose that the nutritional status of hip fracture patients should receive greater attention, and that randomized trials testing for efficacy of aggressive postoperative nutritional interventions may be warranted.

Aims

Implant failure has become more common as the number of primary total ankle arthroplasties (TAAs) performed has increased. Although revision arthroplasty has gained attention for functional preservation, the long-term results remain unclear. This study aimed to assess the long-term outcomes of revision TAA using a mobile-bearing prosthesis in a considerably large cohort; the risk factors for failure were also determined.

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.

This edition of Cochrane Corner looks at some of the work published by the Cochrane Collaboration, covering interventions for treating distal femur fractures in adults; ultrasound and shockwave therapy for acute fractures in adults; and local corticosteroid injection versus placebo for carpal tunnel syndrome.

Some DEFINITIONS are necessary: “STEMS” refers to “intramedullary stem extensions”, which may be of a variety of lengths and diameters, fixed with cement, porous coating or press fit alone and which may be modular or an inherent part of the prosthesis. The standard extension keel on the tibia does not qualify as a “stem (extension)”. COMPLEX implies multiple variables acting on the end result of the arthroplasty with the capability of inducing failure, as well as necessary variations to the standard surgical technique. A lesser degree of predictability is implied. More specifically, the elements usually found in an arthritic knee and used for the arthroplasty are missing, so that cases of COMPLEX primary TKA include: Soft tissue coverage-(not relevant here), Extensor mechanism deficiency-patellectomy, Severe deformity, Extra-articular deformity, Instability: Varus valgus, Instability: Plane of motion, Instability: Old PCL rupture, Dislocated patella, Stiffness, Medical conditions: Neuromuscular disorder, Ipsilateral arthroplasty, Prior incisions, Fixation hardware, Osteopenia, Ipsilateral hip arthrodesis, Ipsilateral below knee amputation, etc. Complexity includes MORE than large deformity, i.e., success with large deformity does NOT mean success with constrained implants regardless of indication. In addition, the degree of constraint must be specified to be meaningful. NECESSARY presumably this means: “necessary to ensure durable fixation in the face of poor bone quality or more mechanically constrained” and SUFFICIENT suggests that stems, by themselves or in some shape of form, by themselves “will ensure success (specifically here) of fixation”. If we can start with the second proposal, that STEMS are SUFFICIENT for success the answer is: “NO”, many more aspects of surgical technique and implant design are required. Even if all other aspects of the technique are exemplary, some types of stems or techniques are inadequate, e.g., completely uncemented, short stem extensions. The answer to the first proposal is: “YES, in many cases”. The problem will be to determine which cases. There are philosophical analogies to this question that we already know the answer to. ANALOGY: Is a life-raft necessary on a boat? Yes, you may not use it, but it is considered necessary. Is a life-raft “sufficient” on a boat? No, other problems may occur. Are seat belts necessary? Are child seats necessary? The AAOS already has a position on child restraints, an analogous situation, where a party who cannot control their situation (anesthetised patient/ child) functions in the care of a responsible party. The objection may be argued in terms of cost saving by NOT using increased fixation. A useful analogy, (that would of course require specific analysis), is that of patellar resurfacing: universal resurfacing is cost-effective when considering the expense of even a small number of secondary resurfacings. Of course a complex arthroplasty that requires a revision procedure is far more expensive than secondary patellar resurfacing and so universal use of the enhanced fixation in the face of increased constraint makes sense. The human cost of revision surgery tips the balance irrefutably. DANGER-We must avoid the glib conclusion, often based on poor quality data, that constrained implants do not need additional intramedullary fixation (with stem extensions). When “complexity” is involved, complex analysis is appropriate to select the best course

Aims

The aims of this study were to describe the epidemiology of metacarpal shaft fractures (MSFs), assess variation in treatment and complications following standard care, document hospital resource use, and explore factors associated with treatment modality.

Intramedullary infection in long bones represents a complex clinical challenge, with an increasing incidence due to the increasing use of intramedullary fixation. We report a prospective case series using an intramedullary reaming device, the Reamer–Irrigator–Aspirator (RIA) system, in association with antibiotic cement rods for the treatment of lower limb long bone infections. A total of 24 such patients, 16 men and eight women, with a mean age of 44.5 years (17 to 75), 14 with femoral and 10 with tibial infection, were treated in a staged manner over a period of 2.5 years in a single referral centre. Of these, 21 patients had had previous surgery, usually for fixation of a fracture (seven had sustained an open fracture originally and one had undergone fasciotomies). According to the Cierny–Mader classification system, 18 patients were classified as type 1A, four as 3A (discharging sinus tract), one as type 4A and one as type 1B. Staphylococcus species were isolated in 20 patients (83.3%). Local antibiotic delivery was used in the form of impregnated cement rods in 23 patients. These were removed at a mean of 2.6 months (1 to 5). Pathogen-specific antibiotics were administered systemically for a mean of six weeks (3 to 18). At a mean follow-up of 21 months (8 to 36), 23 patients (96%) had no evidence of recurrent infection. One underwent a planned trans-tibial amputation two weeks post-operatively due to peripheral vascular disease and chronic recalcitrant osteomyelitis of the tibia and foot. The combination of RIA reaming, the administration of systemic pathogen-specific antibiotics and local delivery using impregnated cement rods proved to be a safe and efficient form of treatment in these patients.

Aims

Biofilm-related infection is a major complication that occurs in orthopaedic surgery. Various treatments are available but efficacy to eradicate infections varies significantly. A systematic review was performed to evaluate therapeutic interventions combating biofilm-related infections on in vivo animal models.

We identified 25 children (10 girls and 15 boys) who had been treated with single bone intramedullary fixation for diaphyseal fractures of both forearm bones. Their mean age was 10.75 years (4.6 to 15.9). All had a good functional outcome. We conclude that in selected children, single bone intramedullary nailing is a suitable method of treatment for diaphyseal fractures of both bones of the forearm

Limb deformity is common in patients presenting for knee arthroplasty, either related to asymmetrical wear patterns from the underlying arthritic process (intra-articular malalignment) or less often major extra-articular deformity due to prior fracture malunion, childhood physical injury, old osteotomy, or developmental or metabolic disorders such as Blount's disease or hypophosphatemic rickets. Angular deformity that is above the epicondyles or below the fibular neck may not be easily correctable by adjusted bone cuts as the amount of bone resection may make soft tissue balancing impossible or may disrupt completely the collateral ligament attachments. Development of a treatment plan begins with careful assessment of the malalignment which may be mainly coronal, sagittal, rotational or some combination. Translation can also complicate the reconstruction as this has effects directly on location of the mechanical axis. Most intra-articular deformities are due to the arthritic process alone, but may occasionally be the result of intra-articular fracture, periarticular osteotomy or from prior revision surgery effects. While intra-articular deformity can almost always be managed with adjusted bone cuts it is important to have available revision type implants to enhance fixation (stems) or increase constraint when ligament balancing or ligament laxity is a problem. Extra-articular deformities may be correctable with adjusted bone cuts and altered implant positioning when the deformity is smaller, or located a longer distance from the joint. The effect of a deformity is proportional to its distance from the joint. The closer the deformity is to the joint, the greater the impact the same degree angular deformity will have. In general deformities in the plane of knee are better tolerated than sagittal plane (varus/valgus) deformity. Careful pre-operative planning is required for cases with significant extra-articular deformity with a focus on location and plane of the apex of the deformity, identification of the mechanical axis location relative to the deformed limb, distance of the deformity from the joint, and determination of the intra-articular effect on bone cuts and implant position absent osteotomy. In the course of pre-operative planning, osteotomy is suggested when there is inability to correct the mechanical axis to neutral without excessive bone cuts which compromise ligament or patellar tendon attachment sites, or alternatively when adequate adjustment of cuts will likely lead to excessive joint line obliquity which can compromise ability to balance the soft tissues. When chosen, adjunctive osteotomy can be done in one-stage at the time of TKA or the procedures can be done separately in two stages. When simultaneous with TKA, osteotomy fixation options include long stems added to the femoral (or tibial) component for intramedullary fixation, adjunctive plate and screw fixation, and antegrade (usually locked) nailing for some femoral osteotomies. Choice of fixation method is often influenced by specific deformity size location, bone quality and amount, and surgeon preference. Surgical navigation, or intra-operative x-ray imaging methods (or both) have both been used to facilitate accurate correction of deformity in these complex cases. When faced with major deformity of the femur or tibia, with careful planning combined osteotomy and TKA can result in excellent outcomes and durable implant fixation with less constraint, less bone loss, and better joint kinematics than is possible with modified TKA alone

We describe ten patients with Turner’s syndrome (karyotype 45, XO) who had leg lengthening for short stature. A high incidence of postoperative complications was encountered and many patients required intramedullary fixation as a salvage procedure. We discuss the reasons for this and highlight the differences between our findings and those of a similar series recently reported. In view of the considerable difficulties encountered, we do not recommend leg lengthening in Turner’s syndrome

Presenters Position:. Purpose of Study:. To perform a retrospective audit of the spectrum of management of tibial pseudarthrosis by a single surgeon over a seven year time period. Description of Methods:. All discharge summaries and operation logs from 2004 to 2011 were reviewed to identify patients, and their case notes and x-rays were examined. Patients were contacted telephonically for follow-up examination. Summary of Results:. Eleven patients presented with pseudarthrosis or bowing of the tibia (six females, five males, age range 4 months–7 years). Three were being treated conservatively and two patients had undergone primary below-knee amputation for severe deformity and functional deficit. Six patients had undergone resection of the pseudarthrosis with intramedullary fixation with a Williams' rod. Three of these patients had Neurofibromatosis type 1. In all instances autogenous iliac crest bone graft was used. Fibular osteotomy was performed in five of these patients and the fibula was stabilised with a K-wire in four patients. All patients were discharged in an above knee cast. Mean follow-up from 1st surgery was 23.75 (1.5–72) months. In one patient, histology confirmed suspected fibrous dysplasia. One patient had had a revision procedure 12 months prior to last follow-up for re-fracture and rod displacement. Mean residual deformity was recorded as 4.2° (1° to 10°) valgus and 6.6° (−2° to 20°) anterior bowing. We had no instances of non-union or sepsis at latest follow-up in this small series. Conclusion:. Patients with tibial pseudarthrosis have a wide spectrum of presentation. Not every patient requires immediate surgery. Our treatment aim in the young patient is to maintain optimum ambulation, clinical union and alignment with radiographic appearance assuming secondary consideration. In our hands, internal fixation using a Williams' rod with autograft is safe and effective as the initial surgical procedure. Continued follow-up of these patients is mandatory as the risk of complications is high even after apparent union

Purpose of the study:. To determine the outcomes of cases converted from an external fixator to an internal fixation device in the management of limb reconstructions and deformity corrections. Method:. A retrospective review of 18 patients, that underwent a conversion procedure to internal fixation following long term external fixation use, was done. This comprised 24 limbs. Inclusion criteria: All cases of long term external fixator use converted to internal fixation over a 5 year period. Average external fixation time, pin site care, conversion timing, surgical device used as well as outcome were documented. Results:. The mean treatment time in an external fixator was 185 days (61–370). The reasons for conversion included patient dissatisfaction, pin tract sepsis and a refracture. The conversion procedures included 8 intramedullary nail fixations and 16 plate and screw fixations. An acute conversion was identified as an internal fixation that was done in the same sitting as external fixator removal. A delayed conversion was any internal stabilisation that was done thereafter. In total, the complication rate associated with conversion to internal fixation following long term external fixation was 25%, mainly due to persistent non-union or sepsis. In the 8 conversions to intramedullary nails, 7 were acute: 4 had good outcomes with sepsis free union being achieved. 3 had poorer outcomes with a non-union and 2 amputations being documented. The single delayed nailing achieved union. In the 16 conversions to plate fixation, 13 achieved union. 10 were acute conversions and 3 were delayed. The remaining 3 that developed complications included 2 acute conversions with septic non-unions and a single delayed conversion which resulted in sepsis. Conclusion:. Conversion of an external fixator to an internal fixator in a non-acute reconstructive setting has a 75% success rate. In the acute conversion group (19 cases), plate and screw fixation had a superior outcome. In the delayed conversion group (5 cases), intramedullary fixation was favoured

A treatment regime using electrical stimulation in association with a variety of surgical procedures has improved the prognosis in congenital pseudarthrosis of the tibia--one of the most challenging of all orthopaedic disorders. The technique consists of correction of the tibial deformity, intramedullary fixation and cancellous bone grafting, augmented by electrical stimulation using an implanted bone-growth stimulator. Experience with 27 pseudarthroses in 25 patients is presented; of those, 20 have joined. The cases have been reviewed and the causes of failure analysed. These results offer encouragement to the orthopaedic surgeon treating this difficult condition

A comparative study of methods for treating fractures of the distal half of the femur was carried out prospectively in the five-year period January 1973 to December 1977. The three methods compared were conservative treatment on a Thomas' splint, application of a knee-hinged cast-brace at five to seven weeks, and intramedullary nailing. The time in bed, in hospital and to union were compared as was the rate of functional recovery of the knee. It is concluded that the cast-brace provides a safe reliable method of treatment, combining the advantages of non-operative management with the early mobilisation possible with intramedullary fixation but without the disadvantages of surgical treatment

Rates of operative fixation for clavicle fractures have been increasing over recent years, but non-operative treatment remains the most common treatment. However, the reported results of case series of non-operatively and operatively treated clavicle fractures show considerable variation, making comparison difficult. Non-operative treatment leads to unsatisfactory results in approximately 3 – 10% of cases, sometimes requiring delayed surgical intervention. Recent studies exploring predictors of poor results after non-operative treatment have shown that fracture displacement is a significant predictor of poor outcome. However, fracture comminution, angulation, shortening, smoking, age, and fracture type and location are not consistently associated with worse outcomes. This has lead to increased interest in surgical fixation for displaced fractures. Prior to the large randomised trial by the Canadian Orthopaedic Trauma Society (COTS), controlled trials comparing surgery to non-operative treatment provided no significant support for surgical fixation. The COTS study provides some evidence for plating displaced mid-shaft fractures, however, partly due to methodological issues, recent reviews of the topic have concluded that additional, more rigorous studies are required to confirm the findings of the COTS trial. Intramedullary fixation is also popular, but it does not have the weight of evidence of plate fixation

Aims

Stemless humeral implants have been developed to overcome stem-related complications in total shoulder arthroplasty (TSA). However, stemless implant designs may hypothetically result in less stable initial fixation, potentially affecting long-term survival. The aim of this study is to investigate early fixation and migration patterns of the stemless humeral component of the Simpliciti Shoulder System and to evaluate clinical outcomes.

The aim of this study was to evaluate whether duration of surgery correlates with the survival and final outcome of the patient with metastatic bone disease. Between 1999 and 2002, 23 consecutive patients with impending or complete pathological fractures of the femur due to metastatic bone disease caused by variety of malignancies or an unknown primary were reviewed. These fractures were treated with intramedullary fixation in the form of long intramedullary hip screw, long Gamma nail or AO nail. These patients were followed up clinically and radiologically until death from the primary disease. The results obtained demonstrate a mean survival time between 9 days to 12 months. Pain relief was achieved in 90% patients. Ambulatory status was improved in 47% patients. The postoperative course was complicated by four technical and five systemic complications. Intramedullary nailing is a safe and effective method in the treatment of metastatic bone disease. It provides good functional result with pain relief and improved mobility. The operating time does not predictably correlate with the survival and final outcome of the patient

Biodegradable implants made from polyglycolic and polylactic acid co-polymers undergo degradation by hydrolysis which results in loss of their mechanical strength. The degradation of 1.5 mm polyglycolide rods (Biofix) was studied after intramedullary and subcutaneous implantation in rabbits. Two weeks after implantation there was a 73% reduction in strength of the intramedullary implants and a 64% reduction in the subcutaneous implants. Polyglycolide implants were compared with Kirschner wires for intramedullary fixation of extra-articular fractures in the hand. In one group of patients fractures were fixed with a 1.5 mm intramedullary rod and in a similar group a Kirschner wire was used. In both a wire loop was added for extra fixation. At six months there was no significant difference between the two groups. There were no allergic reactions to the polyglycolide implants

Recently, secondary life-threatening inflammatory reactions have been identified with molecular biological techniques in patients with multi-system injuries who were submitted to immediate or early intramedullary fixation of their fractured femora. This phenomenon was called “The second hit”, and it caused ARDS, PE, and Renal Failure. In a consecutive series of 135 trauma patients with high energy long bone fractures, 40 had sustained multiple-injuries. All fractures were reduced and stabilized on admission by AO-Tubular External Fixation systems. After 72–96 hours, this system was converted to an hybrid-ring-tubular system, which had three dimensional stability. They commenced partial weight bearing 24 hours later, and were followed by bony union. One patient developed DVT, none developed ARDS, PE, Renal Failure. Superficial pin-tract infection was common, but no-deep infection and’or osteomyelitis were encountered. With this minimal-invasive surgical technique, life threatening complications were avoided while preserving the integrity of the soft tissue envelope, the critical contributing biological factor for fracture healing

Intraoperative pulmonary fat and bone-marrow embolism is a serious complication of bone and joint surgery. We have investigated the occurrence and incidence of intraoperative embolism in patients undergoing elective lumbar spinal surgery with or without instrumentation. Sixty adult patients with lumbar degenerative disease were examined by intraoperative transoesophageal echocardiography while undergoing posterior lumbar surgery. Of these, 40 underwent surgery with instrumentation and 20 without. Moderate to severe (grade 2 or 3 according to the grading scale of Pitto et al) embolic events were seen in 80% of the instrumented patients but in none of the non-instrumented patients (p < 0.001). The insertion of pedicle screws was particularly associated with large numbers of pulmonary emboli, while the surgical approach, laminectomy, disc removal and bone harvesting were associated with small numbers of emboli. We consider that, as in arthroplasty and intramedullary fixation of fractures, these embolic events are relevant to the development of potentially fatal fat embolism during spinal surgery

1. It appears that fracture of the humeral shaft occurs more often in persons over fifty. This incidence corresponds with that found in a study carried out by the Pennsylvania Orthopaedic Society in 1959. 2. The middle third of the bone is the most vulnerable portion of the shaft, where transverse fracture and radial nerve palsy most commonly occur. 3. Most fractures of the shaft of the humerus are best treated by simple splintage. The degree of radiological deformity that can be accepted is far greater than in other long bones. In this group anterior bowing of 20 degrees or varus of 30 degrees was present before it became clinically obvious and even then the function of the limb was good. 4. Internal fixation is only occasionally indicated but operation on the middle third of the bone increased the chances of delayed union. 5. In the treatment of delayed union intramedullary fixation and the application of slivers of iliac bone is effective in stimulating the fracture to join

Immobilisation causes denervation-like changes in the motor endplates, decreases the content of IGF-I, and increases the number of IGF-I receptors in the spinal cord. In the rat we investigated whether similar changes occur after a fracture of the midshaft of the femur which had been treated by intramedullary fixation with adequate or undersized pins. A more pronounced reduction in muscle wet weight was seen after fixation by undersized pins as well as decreased ash density of the ipsilateral tibia which did not completely return to normal within the 12-week experimental period. The nicotinic cholinergic receptors in the motor endplates of tibialis anterior were increased (p < 0.01) and there was a significant increase (p < 0.02) in IGF-I receptors in the lumbar spinal cord ipsilateral to the fracture after treatment by undersized nails. These changes may be associated with the impaired proprioception, co-ordination and motor activity which are sometimes seen after fractures

Purpose. We retrospectively evaluated the outcome of fibula grafts in upper limb post infectious diaphyseal gap nonunions and assessed the following modifiers: age, site, vascularised/ nonvascularised, and length of the graft on time to union, graft incorporation, complication rate and reoperation rate. Methods. Thirty seven paediatric upper limb segmental defects treated over a period of 10 years were identified. Twenty two post septic defects in 21 children were treated with intramedullary fixation and vascularised/ nonvascularised fibula grafting. Union time was assessed from records and radiographs. Graft incorporation was assessed using Pixel value ratio (Hazra et al). Complications were defined as nonunion, delayed union, implant failure, refractures, graft loss and infection. Results. Twenty one children with 22 nonunions, 9 boys and 12 girls, mean age 6.5 years were followed up for a mean of 24 months. Defects (humerus-8, radius-8, ulna-6) ranged from 10 mm to 85 mm before surgery. Seven vascularised grafts(mean length = 69.9 mm) 3 in ulna and 4 in radius and 14 nonvascularised (48.8 mm) were 8 in humerus, 4 in radius, 3 in ulna. Primary union was 81% at a mean of 4.7 months. Mean pixel value for graft incorporation was 1.3 (SD = 0.2) on immediate postoperative radiograph and 1.08 (SD 0.16) at mean of 2 years. Complications included nonunion requiring surgery in 4, delayed union in 6, wire migration in 6, refractures in 4, infection reactivation in 2 with loss of graft in 1. Time to union was 5.5 (SD 2.9) months in nonvascularised and 3.1 (SD 0.6) in vascualrised group (P = 0.04). Complication rate was 1.2 and 0.2 in nonvascularised and vascularised grafts(p = 0.04). Bone, age and the graft length did not significantly affect union time, graft incorporation, complication and reoperation rate. The complication rate was significantly higher in children ≤8 year; however other outcomes were not significantly different. Conclusion. Vascularised grafts and children aged >8 year did significantly better in fibular grafting for post-septic upper limb diaphyseal nonunions

Purpose: This study was performed to evaluate the results of intramedullary nailing of distal tibial fractures located within 5 cm of the ankle joint. Materials and Method: From 1990 to 2007, 142 tibial fractures that involved the distal 5 cm of the tibia were treated with reamed intramedullary nailing with use of either two or three distal interlocking screws. Twenty-one tibial fractures were open and were treated primarily with external fixation and then with intramedullary nailing. Seventy patients (49%) were under 20 years old, 85 (59%) were men and traffic accident was the main cause of fracture in 58 (41%) patients. 108 patients were treated with GK nail, 14 patients with modified GK nail and 20 patients with S2 nail. All patients were allowed postoperatively full weight bearing with crutches till the fracture healing. Patients were evaluated clinically and radiographs were reviewed every three weeks till fracture healing. Last follow-up was at two years postoperatively. The functional results were evaluated with the Iowa Ankle-Evaluating System. Results: Acceptable radiographic alignment, defined as < 5° of angulation in any plane, was obtained in 135 patients (95%). No patient had any change in alignment between the immediate postoperative and the final radiographic evaluation. We had no non-unions or failures of the implant. Complications included one superficial infection at the entry point of the nail and one iatrogenic fracture at the time of the intramedullary nailing. The fractures united at an average of 12.5 weeks. The functional outcome was determined at one and two years postoperatively. There was improvement in the Iowa Ankle-Evaluating System scores with time. Conclusion: Intramedullary nailing is an effective alternative for the treatment of distal metaphyseal tibial fractures. Simple articular extension of the fracture is not a contraindication to intramedullary fixation. Functional outcomes improve with time

Following successful total knee arthroplasty, tibial periprosthetic fractures are rare and patellar fractures are sufficiently dependent upon vascular issues that they constitute a somewhat separate topic. Femoral periprosthetic fractures are extremely difficult to manage, usually producing flexion, internal rotation, and varus deformities. Malunion from insufficient stabilisation and stiffness from excessive immobilisation are the polar perils to be avoided. A variety of conservative treatment options will be discussed, ranging from casting and traction to open reduction and internal fixation. Within the latter category, recent enthusiasm has swayed the pendulum of therapeutic options towards intramedullary fixation. This can be accomplished using Rush rods, interprosthetic and intramedullary rods with fixation screws, and revisional knee arthroplasty techniques with large intramedullary stems. As a general rule, the more aggressive techniques provide the better results, although the severe technical difficulties of managing the osteopenic femoral medullary bone require special techniques and skills. Nonetheless, optimal results producing less than 5° of angulation and over 100° of motion are to be expected

Intramedullary fixation of the long bones is commonly used to prevent and treat fractures and subsequent deformities in patients with osteogenisis imperfecta. However, there is little in the literature about the management of deformities of the proximal femur, such as coxa vara secondary to malunited proximal fractures. This paper presents a simple surgical technique that holds the femoral neck in a valgus position in osteogenisis imperfecta. Four patients (five hips) presented with an acute fracture of the upper femur and complex proximal deformity with coxa vara. All patients, whose mean age at operation was 6.5 years, were classified as Sillence type III, and none had previously undergone surgery. The femoral deformity was corrected and the femur stabilised with a Williams rod. The unstable proximal segment and femoral neck were fixed with K-wires, which were then bent and secured to the femoral shaft with two cerclage wires. Patients were followed up to radiological union. Pre-operatively the mean neck-shaft angle was 70°, and there were associated complex deformities of the proximal femur and femoral shaft. At the time of surgery, a mean correction of neck-shaft angle of 60( was achieved, giving a mean valgus angle of 130°. The correction was maintained at follow-up. One patient remained ambulant after surgery, two subsequently became ambulant with elbow crutches and one remained non-ambulant

Introduction. Unstable intertrochanteric hip fractures (AO 31A2) continue to be a challenge, as non-locking implants have shown a considerable rate of loss of reduction. Intramedullary fixation has been recommended, although screw cut-out has been identified as problematic. This study was performed to ascertain whether treatments with the established proximal femoral nail (PFN) and the newer PFNA with blade design (proximal femoral nail antirotation) have advantages over the use of the Percutaneous Compression Plate (PCCP, developed by Gotfried). Methods. Cohort study. Between March 2003 and March 2008, 134 patients with unstable fractures were treated with a PCCP, (n=44, 78.3 yrs, ASA 2.8), a PFN (n=50, 77.2 yrs, ASA 2.8), or a PFNA (n=40, 75.8 yrs, ASA 2.6). The patients (31 PCCP, 33 PFN, 30 PFNA) were then reexamined clinically and radiologically after approximately 21 months. Results. The PCCP was found to require less implantation time than the PFN and the PFNA (60 vs. 80 vs. 84 min, p<0.001) and less radiation exposition time (PCCP 139 vs. PFN 283 vs. PFNA 188 seconds, p<0.001). The rate of reoperations due to wound infections and hematomas amounted to 2% for the PCCP, 4% for the PFN, and 5% for the PFNA (p=0.799). Due to mechanical complications, 9% of patients implanted with a PCCP, 13% of those implanted with a PFN, and 5% of those implanted with a PFNA had to be reoperated (p=0.353). The cut-out rate was 2% after implantation of the PCCP, 4% after the PFN, and 5% after implantation of the PFNA (p=0.799). In one case, the shaft was fractured intraoperatively (PFNA). The tip-apex distance for the lower femoral neck screw (PCCP 22mm vs. PFN 30mm vs. PFNA 30mm, p<0.001), stress-related varisation of the collodiaphyseal (CCD) angle (4° for all implants), impaction (PCCP 5mm vs. PFN 5mm vs. PFNA 6mm, p=0.662) and femoral shortening (PCCP 3mm vs. PFN 3mm vs. PFNA 4mm, p=0.876) were not determinants of the postoperative function. On the basis of their scores according to Merle d'Aubigné and Harris, there was no variation in the results of the follow-up examinations. Conclusions. The use of the PCCP for the treatment of unstable trochanteric fractures presents a minimally invasive method of implantation, as well as a promising therapy option with regards to operation time, radiologic examination time, and rate of complications. Processes of impaction due to stress are seldom observed. No benefits could be established in an intramedullary treatment with the PFN or the PFNA; thus, it appears that the higher cost of these implants is avoidable

High complication rates and technical difficulties of intra-medullary fixation in children with osteogenesis imperfecta has prompted the modification of existing rod systems. The Sheffield telescoping intramedullary rod has T-piece which is permanently fixed and is expanded to reduce metaphyseal migration. This study analyses the outcome of this rod system over an 11-year period. 32 rods were inserted in the lower limbs of 11 children with osteogenesis imperfecta. All children had multiple fractures of the bones before rod insertion.24 rods were inserted into femur, of which 3 were exchange procedures for complications. 8 rods were inserted into tibia. 4 children had intramedullary rodding of all the 4 lower limb bones. The outcome was measured in terms of mobility status, incidence of refractures and rod related complications. Complications encountered include 2-rod migrations, one instance each of broken rod, bent rod and valgus drift in the tibia.There was no instance of epiphyseal damage or growth arrest. Our series demonstrates that there is significant reduction in refractures and improvement in the mobility status in children with osteogenesis imperfecta following intramedullary fixation. The frequent complication of T-piece separation and the need for reoperation has been overcome with Sheffield modification of rod design. Though the incidence of rod related complications remain high, our study concludes that Sheffield rod system compares favourably with the existing intramedullary devices for osteogenesis imperfecta in the literature

Practice variation may occur when there is no standardised approach to specific clinical problems and there is a lack of scientific evidence for alternative treatments. Practice variation suggests that a segment of the patient population may be managed sub-optimally, and indicates a need for further research in order to establish stronger evidence-based practice guidelines. We surveyed Australian orthopaedic surgeons to examine practice variation in common orthopaedic presentations. In February 2009, members of the Australian Orthopaedic Association were emailed an online survey, which collected information regarding experience level (number of years as a consultant), sub-specialty interests, state where the surgeon works, on- call participation, as well as five common (anecdotally controversial) orthopaedic trauma cases with a number of management options. Surgeons were asked to choose their one most likely management choice from the list provided, which was either surgical or non-surgical in nature. A reminder was sent two weeks later. Exploratory regression was modeled to examine the predictors of choosing surgical management for each case and overall. Of 760 surgeons, 358 (47%) provided responses. For undisplaced scaphoid fractures, respondents selected short-arm cast (53%), ORIF (22%), percutaneous screw (22%) and long-arm cast (3%). Less experienced (0 to 5 years) (p=0.006) and hand surgeons (p=0.008) were more likely to operate. For a displaced mid-shaft clavicle fracture, respondents selected non-operative (62%), plating (31%) and intramedullary fixation (7%). Shoulder surgeons were more likely to operate (p<0.001). For an undisplaced Weber B lateral malleolus fracture, respondents selected plaster cast or boot (59%), lateral plating (31%), posterior plating (9%) and no splinting (2%). For a displaced Colles fracture in an older patient, respondents selected plating (47%), Kirschner wires (28%), cast/splint (23%) and external fixation (1%). Less experienced (p<0.001) and hand surgeons (p=0.024) were more likely to operate. For a two-part neck of humerus fracture in an older patient, respondents selected non-operative (74%), locking plate (14%), and hemiarthroplasty (7%). Shoulder surgeons were more likely to operate (p<0.001). Accounting for all answers in multiple regression modeling, it was found that more experienced surgeons (>15 years) were 25% less likely to operate (p=0.001). Overall, there was no difference among sub-specialties, or whether a surgeon participated in an on-call roster. Considerable practice variation exists among orthopaedic surgeons in the approach to common orthopaedic problems. Surgeons who identify with a sub-specialty are more likely to manage conditions in their area of interest operatively, and more experienced surgeons are less likely to recommend surgical management

Non-operative treatment is usually employed in the treatment of femoral fractures in young individuals. Malunion, delayed union, joint stiffness, limb length discrepancy, psychological problems and delay in functional recovery are well known complications of conservative treatment. The length of hospital stay that will be a part of non-operative treatment will add to the cost of the treatment. We report our experience with intramedullary nailing of closed femoral shaft fractures with a new femoral nail in adolescent patients with an open physis. We treated 13 patients between 1995 and 2004 aged between 8–16 years (8 males and 5 females) with a new femoral nail for closed femoral shaft fractures using the tip of the greater trochanter as the entry point. 11 of the 13 patients had removal of the femoral nail. The mechanism of injury, length of hospital stay, patient mental well-being, surgical technique, requirement of secondary surgical procedures, associated complications, post-operative mobility, return to pre-injury status, range of movement at the hip and knee are discussed. At follow up ranging from few months to 7 years, we found no leg length discrepancy, rotational deformity, limp, problems with physis and all patients had a full range of movement at the hip and knee. External fixation, elastic intramedullary nails, plate and screw fixation are other surgical options available to treat femoral shaft fractures. Children poorly tolerate external fixators and plate fixation can be associated with a high incidence of complications. Flexible intramedullary fixation of femoral shaft fractures is an attractive option, but is technically difficult and is associated with a learning curve. In our view, intramedullary nailing is a simple, safe, efficient and effective method of treatment of femoral shaft fractures in adolescent patients with open physis
