Introduction. Muscle stiffness and joint contractures are common complications of limb lengthening. Authors have demonstrated less permanent soft tissue complications with intramedullary lengthening than external fixation. Our aim was to evaluate the joint response following intramedullary femoral lengthening and need for physiotherapy and alteration to rate/rhythm of lengthening. Method. A retrospective review of documentation for all femoral Precice nails in our centre inserted between 2012 and 2017. This involved 98 nails (68 antegrade, 30 retrograde) in 88 patients (59 males, 29 females) with a mean age of 32 years (range 12–69 yrs). We excluded cases where there was no documentation regarding Range of Movement (ROM). Bilateral lengthenings were recorded as separate cases. This left 50 antegrade, 16 retrograde cases with hip ROM data and 55 antegrade, 26 retrograde cases with Knee ROM data. Results. Hip. In the antegrade group 20 cases (39%) developed no stiffness throughout treatment. ROM decreased in 61% (n=30) of cases and the median length at which this occurred was 3cm. Where a retrograde nail was inserted 62.5% of cases (n=10) maintained normal range of motion. The median length at which ROM decreased was 3.25cm, this occurred in 6 cases (37.5%). . Knee. Where the antegrade nail was inserted, 22 cases (40%) did not develop stiffness. There was reduced ROM in 33 cases (60%), occurring at a median distance of 2cm. The median distance at which reduced ROM occurred with the retrograde nails was 1.5cm, this occurred in 23 cases (88.5%). 3 cases did not develop stiffness. All cases regained full ROM. Conclusion. Although there was no permanent loss, Joint Stiffness still occurs with intramedullary limb lengthening and there remains the need for regular physiotherapy. There are no data from other institutions for comparison. Rehabilitation guidelines and a proforma to accurately monitor patients ROM throughout treatment have been developed

Clinical Problem. Pilon fractures and distal metaphyseal fractures of the tibia are associated with a high rate of soft tissue and bone healing problems. We started to use the XS and XS nail as minimal invasive procedure for the management of these fractures in July 2000 first for the fibula and since for the fibula and pilon itself but extended metaphseal comminution are contraindication for the XS nail. Because of soft tissue problems and higher loading capacity of intramedullary implants the XS Nail was also used for ankle fracture osteosynthesis but as in all articular fractures with open reduction,. Material and Methods. the XS nail is a 4.5mm or the XXS a 3.5mm straight nail witch is locked by threaded wires witch are placed with an aiming device and allows also dynamic fracture site compression with a set screw. The Fibula is fixed percutaneusly and after distal locking with traction of the aiming device also tibia length and axis can be restored and fixed with the proximal locking. From july 2000 to july2006 54 pilon fractures where treated. The mean age was 54 years (range 25–92). In all cases except one referred after 4 weeks the fibula and joint dislocations where stabilised primarily. The tibia XS nail osteosynthesis or limited invasive plate fixation was performed after 5–8 days except two fixed primarily. Up to now 43 patients could be re-examined more than 12 months after surgery. The results were classified according to the Ovadia Score. In a second study: from 05/2000 to 03/2002 214 ankle fractures were stabilised with a XS or XXS nail. The mean age was 51 year, 59% were woman. 35% were Weber B and 25% type C fractures. The re-examination after 6 months could be performed in 91 Patients and was evaluated according to the Ovadia score (clinical and radiological). Results. All articular pilon fractures and fibula fractures healed without problems but in 3 metaphyseal fractures delayed union required bone grafting. According to the Ovadia Score after one year the results were very good or good in the subjective criteria in 69% of the patients and 61% in the objective criteria. In the ankle fractures study in 2 patients haematoma revisions and in 2 patients with the primary used oblique insertion of the nail a proximal fibula fracture occured. At re-examination 71% showed an excellent and 25% a good result. Conclusion. the minimal invasive stabilisation of pilon fractures with the XS nail and the absence of plates on the bone surface reduces significantly the healin. The Xs nail is also a new option for ankle stabilisation. It improves the stability and reduces the complication of ankle osteosynthesis due to the lack of implant under the skin on the bone surface and due to the higher biomechanical stability of intramedullary implants

Background:. Closed femoral shortening (CFS) is a recognised procedure for managing leg length discrepancy (LLD). Method:. We report twenty-nine consecutive patients with LLD who underwent CFS using an intramedullary saw and nail. Mean age was 29.2 years (16.1–65.8). The primary outcome was accuracy of correction. Secondary outcomes were complications, union, ASAMI score and re-operation, alongside Patient Reported Outcome Measures (PROMs), using EQ5D-5L and GROC. Results:. Mean pre-operative limb length discrepancy was 3.4 cm (1.5–6.5). Mean planned and achieved shortening was 2.9 cm (1.7–5.0). Mean follow-up was 2.0 years (0.2–8.4). Minimal access surgery was possible in all cases but careful technique is essential. All patients achieved a correction within 5mm of the planned shortening (range 0–5mm). 28 patients (97%) achieved uncomplicated union. One patient had a non-union requiring exchange nailing and subsequent compression plating. 13 patients had nail removal at a mean of 1.7 years and 3 had locking screw removal. Patients had an overall positive experience with 81% reporting high PROM scores. Discussion:. This technique offered accurate limb length correction with few complications. Patients rehabilitated well with good functional outcomes. Conclusion;. CFS with an intramedullary saw is a well-tolerated and effective technique when managing LLD up to 5cm

Intramedullary tibial nailing was performed in ten paired cadavers and the insertion of a medial-to-lateral proximal oblique locking screw was simulated in each specimen. Anatomical dissection was undertaken to determine the relationship of the common peroneal nerve to the cross-screw. The common peroneal nerve was contacted directly in four tibiae and the cross-screw was a mean of 2.6 mm (1.0 to 10.7) away from the nerve in the remaining 16. Iatrogenic injury to the common peroneal nerve by medial-to-lateral proximal oblique locking screws is therefore a significant risk during tibial nailing

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

The accuracy of templates used for the preoperative planning of the fixation of intramedullary fractures depends on radiological magnification. To study the accuracy of these templates, we randomly selected 100 femoral and 100 tibial radiographs taken after stabilisation by an intramedullary nail using a standard technique. We then compared the known nail length with the corresponding measurements on the radiographs. The mean magnification factor for the femur was 9% and for the tibia 7%; these differ considerably from the range of magnification of the manufacturers’ templates (femur, 15% to 17%; tibia 10% to 15%). We conclude that templates are unreliable for the selection of implant length and that this should be done by intraoperative measurements

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. Methods. 244 patients with a subtrochanteric femur fracture were treated at one centre over a 21 year period were prospectively studied. 75 were treated with an extramedullary fixation implant and 168 with an intramedullary nail. Surviving patients were followed up till one year from injury. Results. The mean age of patients was 74 and 71% were female. Fixation failure requiring revision surgery occurred in 4% of those treated with an extramedullary implant and 6% of those treated with an intramedullary nail, a difference that was not statistically significant. Length of surgery was similar for both operations but transfusion requirements were less for those treated by the intramedullary nail (p<0.0001). No notable differences in other outcomes were found. Discussion. In summary both intramedullary and extramedullary fixation produce comparable outcomes for this fracture

Introduction and objectives. Intramedullary nailing is indicated to stabilization of tibia shaft fractures. Intramedullary nailing through an infra-patellar incision is commonly the technique of choice. While intramedullary nailing of simple diaphyseal fracture patterns is relatively easy, proximal tibia fractures, extremely comminuted/segmental tibia fractures, politrauma with multiple fractures in both extremities and reconstruction of bone loss segment with stiffness of the knee joint can be very challenging to treat. A novel technique for intramedullary tibia nailing through the patella-femoral joint is described. This technique allow extension tibia during intervention time and it supplies easier reduction of the pattern of fracture above. The purpose of our investigation was to evaluate the use of this new technique in described above pattern fracture and patient situation; because we have thought that new technique can perform better outcomes in this situations. Materials and Methods. An observational study of tibia fractures or bone defect was performed for consecutive patients who presented: proximal tibia fractures, extremely comminuted/segmental tibia fractures, politrauma with multiple fractures in both extremities and reconstruction of bone loss segment in the Trauma unit of our institution from September 2009 to August 2010. A total of 32 were included in our study, which performed surgery intervention with Trigen tibia nail (Smith & Nephew, Memphis) with suprapatelar device. Demographic data, mechanism of injury, fracture classification, ROM (2 and 6 weeks, and 3 months), consolidation rate, reduction fracture quality and knee pain at 3 months were recorded. Results. Male was the gender most frequent (64%), the average age was 39,5 years and the main mechanism of injury was motor vehicle injury (30,6%). There were 7 proximal fractures, 1 bifocal fracture, 6 politrauma and 2 reconstruction bone loss segment, the others were comminuted and segmental tibia fracture. In all the patients, the fracture was consolidated between 8 to 14 weeks with average of 10,6 weeks. The quality of reduction was correct in all patients in different axis. The average of ROM at 2 weeks was (−2°/95°) at 3 months was (−0,4°/133°). The knee pain (VAS) average was 0,6 only in 2 patients were (4). Poller screw was used in 7 patients. Conclusion. The suprapatelar nailing is optimal technique to resolve complex fracture of the tibia (proximal, segmental conminution, politrauma) that perform correct consolidation rate without misalignment in the patients. Concerns about knee pain (VAS) from the technique not appear in our data. Prospective and clinical trials are needed to validate this approach

Background:. External fixators are not as well tolerated around the femur when compared to the tibia. Lengthening with an intramedullary device is therefore attractive. Method:. We reviewed all cases of femoral lengthening performed at our unit from 2007 to 2014. Cases of non-unions, concurrent deformities, congenital limb deficiencies and lengthening with an unstable hip were excluded. This left 33 cases for review. Healing index, implant tolerance and complications were compared. Results and Discussion:. In 20 cases the Precice lengthening nail was used and in 13 cases the LRS external fixator system. The desired length was achieved in all cases in the Precice group and in 12 of 13 cases in the LRS group. The Precice group had a more rapid return to full weight bearing. The mean healing index was 31.3 days/cm in the Precice and 47.1 days/cm in the LRS group. There was an increased incidence of complications with LRS lengthening, including pin site infections and regenerate deformity. Implant tolerance and the patients' perception of the cosmetic result were better with the Precice treatment. Conclusion:. We conclude excellent functional results with fewer complications and greater patient satisfaction in femoral lengthening with a Precice intramedullary nail

Displaced fractures of the forearm in children are often treated conservatively, but there is a relatively high incidence of redisplacement, malunion and consequent limitation of function. We have performed percutaneous Kirschner (K) wire fixation in 72 such children under the age of 14 years, of which 57 were reviewed for our study. Both the radius and ulna were fractured in 45 (79%), the radius only in eight and the ulna only in four. The mean initial angulation was 19° in the lateral plane and 9° in the anteroposterior plane for the radius and 15° and 9°, respectively, for the ulna. In 42 patients (74%) we performed closed reduction. In the remaining 15 (26%) closed reduction failed and an open reduction, through a minimal approach, was required before K wiring. At a mean follow-up of 20 months all patients had good functional results with an excellent range of movement. Only five had angulation of from 10° to 15° and none had nonunion, premature epiphyseal closure or deep infection. Percutaneous intramedullary K wiring for forearm diaphyseal fracture is a convenient, effective and safe operation, with minimal complications

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

Background. For the treatment of proximal humeral fractures two major therapeutic principles can be employed: Intramedullary nailing (PHN) or locking plate osteosynthesis. Aim of this study was to evaluate and compare clinical and radiological long-term outcome of proximal humeral fracture stabilization using PHN or angular stable plating. In addition, we discussed advantages and disadvantages of both techniques and aimed at establishing criteria which operative technique should preferentially be utilized for selected fracture configurations. Materials and Methods. In a prospective study between 2003 and 2010 we analyzed 72 patients with proximal humeral fracture who had been treated by PHN (44 patients) or angular stable plating (28 patients) in a European Level 1 Trauma Center. In the two cohort groups the following epidemiologic data was found. 46 patients were women, and 26 men with a mean age of 60.6 years (range 18–91). Follow-up was performed 38–82 months after accident, on average. Mechanism of injury was fall in 59, motor cycle accident in 4, bike accident in 8 patients, and fall from horse in 1 patient. Duration time between accident and operation was 2.8 days on average. Osteoporosis was previously known in 20 out of all evaluated patients (plate: 7/28; nail: 13/44). Fractures were classified using the Neer classification and Binary description system: There were 35 3-part fractures (PHN: 26; plate: 9) and 37 4-part fractures (PHN: 18; plate: 19), respectively. Functional and radiological outcome was assessed in a range of 38–82 months after trauma using Constant Score. Results. No clinical symptoms after 3 years were observed in 40 patients, whereas in 32 patients clinical symptoms were evaluated related to pain and/or loss of function. Secondary revision after plate fixation had to be performed in 5 out of 28 patients and in 11 out of 44 patients in the PHN group. Functional outcome using the Constant score demonstrated a total score of 72.9 (ipsi-lateral side) vs. 88.4 (contra-lateral side) in all evaluated patients, on average. Complete metal removal was performed in 34 out of 72 patients (PHN: 17; plate: 17). Conclusion. Both i.m. nailing and angular stable plating are adequate treatment options for proximal humeral fractures. No significant differences in outcome between implants regarding fracture healing, nonunion, and infection were found. Locked plating can be utilized for all distal humerus fracture including complex 4-part fractures. I.m. nailing provides favorable intramedullary stability and can be successfully implanted in multi-segmental fractures of the upper extremity. However, both systems require precise preoperative planning and advanced surgical experience. Clinical long-term outcome largely depends on surgical technique and not so much on the choice of implant

Introduction. Since 2001 we use the flexible intramedullary nailing (FIN) in bone lengthening in children. This study estimates results of EF+FIN association considering the duration of external fixation and complications. Materials and Methods. Since 2001 we performed 294 bone lengthenings (338 segments of UL and LL) in 250 children 3 to 16 years old (11.01±0.23 in average). The length discrepancy was congenital in 163 cases, the sequelae of trauma or osteomyelitis were observed in 87 patients. In group I (195 cases) the Ilizarov fixator alone was applied, in group II the Ilizarov fixator (91 cases) or TSF® (8cases) were combined with FIN. The healing index was compared between the groups of the same etiology with similar type of distraction osteosynthesis. The date of consolidation corresponded to the day of removal of the external fixator, while intramedullary nails remained in place thus protecting the bone. Healing index was calculated by relating the duration of wearing of the external fixator (in days) and the amount of lengthening (in cm). Results. Reduction of the healing index is noted in each compared category. Thus, in congenital shortening in monofocal distraction osteosynthesis of the femur the healing index decreased from 29.8 (group I) to 20.4 days per cm, in bifocal tibial lengthening from 22.7 (group I) to 16.3d/cm (group II), in humeral lengthening – from 30.2 to 21.3 d/cm. In fact, it appears that the association of the external fixator of the Ilizarov type or TSF® with FIN allows to reduce the healing index significantly: in 12 of 16 compared categories the reduction of the index was from 20% to 40% or from 4.0 to 19.1 days per cm. In group I four cases of deep infection of soft tissues, 2 osteomyelitis, 21 fractures or deformities after frame removal were manifested. In group II – onlyone case of deformation after frame removal, absence of severe infectious complications, 8 cases of migration of the intramedullary wires. Discussion. FIN creates an elastic and resistant system during the lengthening. We even suggest that it stimulates the formation considering an apparent decrease of the healing index. On the other hand, the elasticity of nails prevents secondary fractures or deformations after frame removal. Conclusion. Combination of the circular EF and FIN in limb lengthening in children significantly decreases the duration of external fixation and the amount of severe infections and fractures

Aims

This is a prospective randomised controlled trial comparing the functional outcomes of plate fixation and elastic stable intramedullary nailing (ESIN) of completely displaced mid-shaft fractures of the clavicle in the active adult population.

Background

The optimal treatment of segmental tibial fractures (STF) is controversial. Intramedullary nailing (IMN) and external fixation (EF) have unique benefits and complications.

Introduction

Fractures of the distal tibia can be challenging to manage. Numerous surgical techniques have been utilised in managing these however there remains debate as to the optimum method of fixation. This study aims to assess the surgical outcomes and PROMs of patients with distal tibial fractures managed with intramedullary-nails or ring fixation.

Background

In a systematic review of 1125 distal tibia fractures treated with an intramedullary nail, the reported incidence of malalignment was 14%. The purpose of our study is to assess whether the addition of blocking screws during intramedullary nailing of a distal tibia fracture improved radiological outcomes. As a secondary outcome, the time to radiographic union was compared to see if a more rigid bone-implant construct had an effect on healing.

Intramedullary nails are a well accepted method of fixing fractures of the femur, however there are several potential complications associated with femoral nail insertion. One under-reported complication is perforation of the anterior cortex of the distal femur. Cortical perforation is well documented in immature bone however there is little evidence of perforation in skeletally mature adults.

We present a 5 year retrospective clinical audit into correct positioning of the TriGen™ intramedullary nail system (Smith & Nephew Inc.), with respect to determining the anterior cortex perforation rate. Cases were identified using searches of the electronic operation notes, followed by manual cross checking of the reference numbers of the implants used. The radiographs for each case were then checked to identify cases of distal anterior cortex perforation. 138 femoral nails were inserted over the 5 years 2005–2010 at our institution. 79 cases met the inclusion criteria, of which 8 were deemed to show radiological evidence of cortical perforation on lateral view, this represents a perforation rate of 10.1% in this population. There was also a significant difference in the mean age of the perforated vs non-perforated groups (80.1 vs 62.1 yrs respectively). These results are at odds with the current literature which reports few or no cases of cortical perforation. As a result of this audit we have made various recommendations for future practice. This study highlights a need for larger scale randomised trials to be carried out in the future.

We reviewed our results and complications of using a pre-bent 1.6mm Kirschner wire (K-wire) for extra-articular metacarpal fractures. The surgical procedure was indicated for angulation at the fracture site in a true lateral radiograph of at least 30 degrees and/or in the presence of a rotatory deformity.

A single K-wire is pre-bent in a lazy-S fashion with a sharp bend at approximately 5 millimetres and a longer smooth curve bent in the opposite direction. An initial entry point is made at the base of the metacarpal using a 2.5mm drill by hand. The K-wire is inserted blunt end first in an antegrade manner and the fracture reduced as the wire is passed across the fracture site. With the wire acting as three-point fixation, early mobilisation is commenced at the metacarpo-phalangeal joint in a Futuro hand splint.

The wire is usually removed with pliers post-operatively at four weeks in the fracture clinic.

We studied internal fixation of 18 little finger and 2 ring finger metacarpal fractures from November 2007 to August 2009. The average age of the cohort was 25 years with 3 women and 17 men. The predominant mechanism was a punch injury with 5 diaphyseal and 15 metacarpal neck fractures. The time to surgical intervention was a mean 13 days (range 4 to 28 days). All fractures proceeded to bony union. The wire was extracted at an average of 4.4 weeks (range three to six weeks). At an average follow up of 8 weeks, one fracture had to be revised for failed fixation and three superficial wound infections needed antibiotic treatment.

With this simple and minimally invasive technique performed as day-case surgery, all patients were able to start mobilisation immediately.

The general outcome was good hand function with few complications.

We performed a prospective, randomised trial in 39 patients with open tibial fractures treated initially by external fixation to compare cast immobilisation (group A) and intramedullary nailing (group B) as a sequential protocol planned from the onset of treatment.

The results showed that group B achieved faster union (p < 0.05) than group A with less malunion or shortening and a greater range of movement. Patients treated by intramedullary nailing required fewer radiographs and outpatient visits (p = 0.0015) and had a more predictable and rapid return to full function.

We feel that these severe fractures are better treated by delayed intramedullary nailing and that this has an acceptable rate of complications.
