This study aimed to investigate the outcomes of open tibia shaft fractures at a level one trauma center in a developing world setting. Specific objectives were to determine the association of time delay to antibiotic administration, surgical debridement, definitive skeletal stabilisation and soft tissue reconstruction, and the development of fracture-related infection (FRI). A retrospective cohort study included all adult patients with open tibia shaft fractures from July 2014 to June 2016 and January 2018 to December 2019. Patients who were skeletally immature at the time of injury, those with pathological fractures and who did not complete follow-up of at least three months were excluded. Patients were identified from hospital records. Data was captured in Microsoft Excel and analysed using STATISTICA. A Chi-squared was used to detect significant differences between groups. No association between infection and antibiotic administration was observed when patients were treated within or after 3 hours (p=0.625) or if patients had their first surgical debridement in theatre before or after 24 hours (p=0.259). Patients who waited more than five days for definitive skeletal fixation or soft tissue reconstruction had a significant increase in FRI (OR 4.7, 95% CI 2.0 – 10.9 and OR 4.7, 95% CI 2.0 – 11.0, respectively). Patients who underwent more than two formal debridements had a higher risk of developing FRI (OR 15.6, 95% CI 5.8 – 41.6). Whilst administration of antibiotics within 3 hours of presentation to the emergency unit had no impact on the development of FRI, time delays in managing open tibia shaft fractures are associated with an increased risk for FRI. Definitive soft tissue reconstruction and skeletal stabilization should not be delayed for more than five days

Māori consistently have poorer health outcomes compared to non-Māori within Aotearoa. Numerous worldwide studies demonstrate that ethnic minorities receive less analgesia for acute pain management. We aimed to compare analgesic management of a common orthopaedic injury, tibial shaft fracture, between Māori and non-Māori. A retrospective cohort study from January 1. st. , 2015, to December 31. st. 2020 inclusive. Eligible patients were 16–65 years old and had isolated closed tibial shaft fractures. 104 patients were included in the study, 48 Māori and 56 Non-Māori. Baseline demographics were similar between the 2 cohorts. The primary outcome measure was type of analgesia charted on the ward. Secondary outcome measures were pre-hospital medications given, pain scores on arrival to the emergency department (ED) and the ward, time to analgesia in ED and type of analgesia given in ED. Statistics were calculated using Fisher's exact test, Pearson's chi-squared test or Wilcoxson's rank sum test as appropriate. No statistically significant differences were found in opiates or synthetics charted to Māori vs Non-Māori (83% vs 89% and 77% vs 88% respectively), opiates given in ED, time to analgesia in ED or ED and ward arrival pain scores. Of statistical significance is that Māori were less likely to receive pre-hospital medication compared to Non-Māori (54% vs 80% respectively, p=0.004). Māori were significantly less likely to receive pre-hospital pain medication compared to Non-Māori. However no other statistically significant findings were found when comparing pain scores, time to analgesia or type of pain relief charted for Māori vs non-Māori. The reasons for Māori receiving significantly less prehospital medication were not explored in this study and further investigation is required to reduce the bias that exists in this area

The choice of whether to perform antegrade intramedullary nailing (IMN) or plate fixation (PF) poses a conundrum for the surgeon who must strike the balance between anatomical restoration while reducing elbow and shoulder functional impairment. Most humeral middle third shaft fractures are amenable to conservative management given the considerable acceptable deformity and anatomical compensation by patients. This study is concerned with the patient reported outcomes regarding shoulder and elbow function for IMN and PF respectively. A prospective cohort study following up all the cases treated surgically for middle third humeral fractures from 2016 to 2022 at a single centre. Telephonically an analogue pain score, an American Shoulder and Elbow Society (ASES) score for shoulder function and the Oxford Elbow score (OES) for elbow function were obtained. One hundred and three patients met the inclusion criteria. Twenty four patients participated in the study, fifteen had IMN (62.5%) and nine had PF (37.5%.). The shoulder function outcomes showed no statistical difference with an average ASES score of sixty-six for the IMN group and sixty-nine for the PF group. Women and employed individuals expressed greater functional impairment. Hand dominance has no impact on the scores of elbow and shoulder function post operatively. The impairment of abduction score post antegrade nailing was higher in the antegrade nailing group than the plated group. The OES demonstrated greater variance in elbow function in the PF group with the IMN group expressing greater elbow disfunction. This study confirms that treatment of middle third humerus shaft fractures by plate fixation is marginally superior to antegrade intramedullary nailing in preserving elbow function and abduction ability

Delayed management of high energy femoral shaft fractures is associated with increased complication rates. It has been suggested that there is less urgency to stabilize lower energy femoral shaft fractures. The purpose of this study was to evaluate the effect of surgical delay on 30-day complications following fixation of lower energy femoral shaft fractures. Patients ≥ 18 years who underwent either plate or nail fixation of low energy (falls from standing or up to three steps' height) femoral shaft fractures from 2005 – 2016 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) via procedural codes. Patients with pathologic fractures, fractures of the distal femur or femoral neck were excluded. Patients were categorized into early (< 2 4 hours) or delayed surgery (2–30 days) groups. Bivariate analyses were used to compare demographics and unadjusted rates of complications between groups. A multivariable logistic regression was used to compare the rate of major and minor complications between groups, while adjusting for relevant covariables. Head injury patients and polytrauma patients are not included in the NSQIP database. Of 2,716 lower energy femoral shaft fracture patients identified, 2,412 (89%) were treated within 1 day of hospital admission, while 304 (11.2%) were treated between 2 and 30 days post hospital admission. Patient age, American Society of Anesthesiologists (ASA) classification score, presence of diabetes, functional status, smoking status, and surgery type (nail vs. plate) were significantly different between groups (p After adjusting for all relevant covariables, delayed surgery significantly increased the odds of 30-day minor complications (p=0.02, OR = 1.48 95%CI 1.01–2.16), and 30-day mortality (p < 0 .001), OR = 1.31 (95%CI 1.03–2.14). The delay of surgical fixation of femoral shaft fractures appears to significantly increase patients' risk of minor adverse events as well as increase mortality. With only 89% of patients being treated in the 24 hour timeframe that constitutes best practice for treatment of femoral shaft fractures, there remains room for improvement. These results suggest that early treatment of all femoral shaft fractures, even those with a lower energy mechanism of injury, leads to improved outcomes

The use of shorter humeral stems in reverse shoulder arthroplasty has been reported as safe and effective. Shorter stems are purported to be bone preserving, easy to revise, and have reduced surgical time. However, a frequent radiographic finding with the use of uncemented short stems is stress shielding. Smaller stem diameters reduce stress shielding, however, carry the risk of varus or valgus malalignment in the metadiaphyseal region of the proximal humerus. The aim of this retrospective radiographic study was to measure the true post-operative neck-shaft (N-S) angle of a curved short stem with a recommended implantation angle of 145°. True anteroposterior radiographs of patients who received RTSA using an Ascend Flex short stem at three specialized shoulder centres (London, ON, Canada, Lyon, France, Munich, Germany) were reviewed. Radiographs that showed the uncemented stem and humeral tray in orthogonal view without rotation were included. Sixteen patients with proximal humeral fractures or revision surgeries were excluded. This yielded a cohort of 124 implant cases for analysis (122 patients, 42 male, 80 female) at a mean age of 74 years (range, 48 – 91 years). The indications for RTSA were rotator cuff deficient shoulders (cuff tear arthropathy, massive cuff tears, osteoarthritis with cuff insufficiency) in 78 patients (63%), primary osteoarthritis in 41 (33%), and rheumatoid arthritis in 5 (4%). The humeral component longitudinal axis was measured in degrees and defined as neutral if the value fell within ±5° of the humeral axis. Angle values >5° and < 5 ° were defined as valgus and varus, respectively. The filling-ratio of the implant within the humeral shaft was measured at the level of the metaphysis (FRmet) and diaphysis (FRdia). Measurements were conducted by two independent examiners (SA and TW). To test for conformity of observers, the intraclass correlation coefficient (ICC) was calculated. The inter- and intra-observer reliability was excellent (ICC = 0.965, 95% confidence interval [CI], 0.911– 0.986). The average difference between the humeral shaft axis and the humeral component longitudinal axis was 3.8° ± 2.8° (range, 0.2° – 13.2°) corresponding to a true mean N-S angle of 149° ± 3° in valgus. Stem axis was neutral in 70% (n=90) of implants. Of the 34 malaligned implants, 82% (n=28) were in valgus (mean N-S angle 153° ± 2°) and 18% (n=6) in varus position (mean N-S angle 139° ± 1°). The average FRmet and FRdiawere 0.68 ± 0.11 and 0.72 ± 0.11, respectively. No association was found between stem diameter and filling ratios (FRmet, FRdia) or cortical contact with the stem (r = 0.39). Operative technique and implant design affect the ultimate positioning of the implant in the proximal humerus. This study has shown, that in uncemented short stem implants, neutral axial alignment was achieved in 70% of cases, while the majority of malaligned humeral components (86%) were implanted in valgus, corresponding to a greater than 145° neck shaft angle of the implant. It is important for surgeons to understand that axial malalignment of a short stem implant does influence the true neck shaft angle

Purpose. Tibial and femoral component overhang in total knee arthroplasty (TKA) is a source of pain, thus is it important to understand anatomic differences between races to minimize overhang by matching the tibial and femoral shaft axis to the knee articular surface. Thus, this study compared knee morphology between Caucasian and East Asian individuals to determine the optimal placement of tibial and femoral stems. Methods. A retrospective study was conducted on a matched cohort of 50 East Asians (21F, 29M) and 50 Caucasians (21F, 29M) by age and gender. CT scans were obtained in healthy volunteers using <2mm slices. The distance from the proximal tibial diaphysis axis to the tibial plateau center was measured, and the distance from the distal femoral diaphysis axis to the center of distal femoral articular surface was measured. Tibial measurements were made using Akagi's AP axis and the widest ML diameter, and femoral measurements were based on Whiteside's line and the surgical epicondylar axis. Results. The ML distance between the tibial shaft center and Akagi line was significantly higher for Asians (9.9mm±2.7, Caucasians 7.7mm±3.1, p<0.001). The distance between the femoral shaft center and Whiteside line was lower, although not significantly different (Asians 1.9mm±1.0, Caucasians 2.2mm±1.1, p=0.11). However, there were no differences in the AP dimension for the femur or tibia comparing Asians to Caucasians. Conclusion. East Asian individuals have more offset in the ML dimension for the tibia. This should be taken into consideration when designing primary and revision TKA stemmed tibial implants for East Asian patients

Abstract. Background. With the increasingly accepted method of suprapatellar tibial nailing for tibial shaft fractures, we aimed to compare intraoperative and postoperative outcomes of infrapatellar (IP) vs suprapatellar (SP) tibial nails. Methods. A retrospective cohort analysis of 58 patients. 34 SP tibial nails over 3 years versus 24 IP tibial nails over a similar time frame. We compared; radiation exposure, patient positioning time (PPT), non-union rate and follow-up time. Knee pain in the SP group was evaluated, utilising the Hospital for Special Surgery (HSS) Knee injury and Osteoarthritis outcome score (KOOS). Results. 58 patients with a mean age of 43 years were included. Mean intraoperative radiation dose for SP nails was 61.78cGy (range 11.60 to 156.01cGy) vs 121.09cGy (range 58.01 to 18.03cGy) for IP nails (p < 0.05). Mean PPT for SP nails was 10 minutes vs 18 minutes for IP nails (p < 0.05). All fractures united in the SP group vs one non-union in the IP group. Mean follow-up was 5.5 months vs 11 months in the SP and IP group respectively. Mean KOOS was 7 (range 0 to 22) at 6 months for the SP group. Conclusion. The semi extended position (SP group) leads to reduced radiation exposure because of ease of imaging. All Patients in the SP group showed improved outcomes, with shorter follow-up and fracture union. The KOOS revealed SP nail patients had minimal pain and good knee function. This study establishes a management and PROMs baseline for ongoing evaluation of SP nails

The aim of this audit was to assess the union rate of humeral shaft fractures treated conservatively in a functional brace in our unit, compared to a “gold standard” of 98% as reported by Sarmiento (JBJS 1977). A retrospective clinical and radiographic review of 155 closed humeral shaft fractures managed with a humeral brace from 2005–2012 was performed. Pathological fractures and patients under 18 were excluded. The mean age was 60 (18–94) with 45 males and 72 females. 15 (10%) patients under 18 and 8 (5%) pathological fractures were excluded; 15 (10%) patients were lost to follow up. Of the remaining 117 fractures, 83 (71%) went on to union and 34 (29%) developed a non-union. Mean time to union was 131 days (47–622). 80% of distal fractures and 75% of midshaft fractures united but only 58% of proximal fractures went on to unite. There was no significant difference in union rates between multi fragmentary (> 3 parts) and simple fracture patterns (69% vs 71% respectively). Our study suggests that a lower threshold for operative intervention of proximal third humeral shaft fractures may be required

Background. Leg length discrepancy (LLD) after intramedullary nailing of femoral shaft fractures is a common problem reported in up to 43% of cases. Comminuted fractures with radiographic loss of bony landmarks have an increased possibility of being fixed with unequal leg lengths. Aims. The purpose of this report is to evaluate the efficacy of routinely obtaining a CT scanogram post-operatively on patients of comminuted femoral shaft fractures treated with intramedullary nailing and immediate correction of limb length inequality if indicated. Results. Twenty one patients with comminuted femoral shaft fractures that were treated with intramedullary nailing and underwent a CT scannogram for evaluation of LLD were included in the study. There were 12 patients with Winquist III and 9 with a Winquist IV fracture pattern. Following surgery leg lengths were measured from the CT scanograms using a computerised measuring ruler. The largest leg length discrepancy noted on scannogram was 4 cm. The average limb length discrepancy was 0.67 cm. Eight patients had a discrepancy of 1cm or greater. We also measured the tibial length in all patients and found only 3 patients with exactly equal tibial lengths. A tibial length discrepancy less than 5mm was observed in 11 patients. In 7 patients it was between 5-9mm and in 3 patients it was 10mm or greater. Four patients underwent leg length correction during the same admission. Conclusion. The decision to undertake correction of the LLD is primarily dependant on the degree of discrepancy. The degree of LLD that requires correction remains undefined. In this study LLD of greater than 15mm was considered for equalisation. Immediate equalisation saves cost, morbidity, delayed sequelae and litigation. Tibial length discrepancy may contribute to the total leg length discrepancy and requires consideration. We recommend a post-operative scanogram costing $380 in patients of comminuted femoral shaft fractures treated with intramedullary nailing

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

Delayed union and non-union are complications of fracture healing associated with pain and with functional and psychosocial disability. This study compares the effect on self-reported health outcomes of delayed union or non-union of femoral and tibial shaft fractures treated at two major metropolitan trauma centres in Victoria. Patients admitted to the Royal Melbourne Hospital and The Alfred with extra- articular femoral and tibial shaft fractures during 2003-2004 and 2005-2006, and followed up by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) were included. Hospital medical records were reviewed to identify the outcome of each fracture. Fracture healing was assessed by the need for unplanned revision surgery for delayed union or nonunion, and clinical and radiological evidence of union. Prospectively-gathered VOTOR health outcome measurements included the Short Form 12-Item Health Survey (SF-12), and return to work and pain status at 6 and 12 months post injury. Of the 520 patients, 260 femoral and 282 tibial shaft fractures were included. In total, 285 fractures progressed to union, 138 fractures developed delayed union or non-union and 119 fractures had an unknown outcome. Factors that were significantly different between the union and delayed union or non-union groups included: fund source, mechanism of injury, other injuries, wound and Gustilo type, and fixation method. On linear regression modelling, an inverse relationship was demonstrated between delayed union or nonunion and the Physical and Mental Component Summary scores of the SF-12. This was statistically significant at both 6 and 12 months post injury unadjusted and adjusted for age, gender and other injuries. On logistic regression modelling, patients with delayed union or non-union showed unadjusted and adjusted risk ratios of 0.85 and 0.82, respectively at 6 months, and 0.82 and 0.76, respectively at 12 months to return to work. Similarly, patients with delayed union or nonunion had unadjusted and adjusted risk ratios of 1.09 and 1.11, respectively at 6 months, and 1.33 and 1.37, respectively at 12 months to have pain. Both were statistically significant at 12 months post injury unadjusted and adjusted for age, gender and other injuries. Patients with delayed union or non-union of femoral and tibial shaft fractures have poorer physical and mental health at 6 and 12 months post injury. In addition, they are less likely to have returned to work and more likely to still have pain at 12 months post injury

Purpose of study:. To assess the effectiveness of a novel locked intra-medullary device in the treatment of acute clavicle shaft fractures. Description of methods:. Patients admitted with midshaft clavicle fractures were assessed for inclusion in the study. Inclusion criteria were mid shaft clavicle fractures with 100% displacement; more than 1, 5 cm of shortening or containing a displaced butterfly segment. Fractures were assessed for suitability to intra-medullary fixation (fracture distance from the medial and lateral end of the clavicle, medullary diameter and fracture type). 35 patients were treated operatively using the device by the author. Post-op, patients were kept in a master sling for a period of 6 weeks and followed up for a period of at least 3 months. Fracture reduction, fracture progression to union, scar size, Dash score, Constant Shoulder score, patient satisfaction and complications were assessed at follow-up by the surgeon, a radiologist and an occupational therapist. Summary of results:. 35 patients, 26 males and 9 females with a mean age of 29 were included in the study. All fractures treated achieved union within expected limits with no operative complications. Excellent cosmetic results were achieved in 34 patients with a high level of patient satisfaction reported. 3 patients developed post-operative complications – 2 nail failures and 1 hardware sepsis. All 3 complications were due to inferior implant placement due to initial surgeon inexperience with the device and patient non-compliance with the post-operative regime. Conclusion:. Locked intra-medullary fixation of clavicle shaft fractures that fit the criteria for operative fixation was found to be a reliable, safe method of achieving fracture reduction and fracture union in 35 patients treated. The operation is moderately demanding with a short learning curve

Introduction of the National Hip fracture database, best practice tariff and NICE guidelines has brought uniformity of care to hip fracture patients & consequently improved outcomes. Low energy femoral shaft fractures of the elderly are not within these guidelines, but represent a similar though significantly smaller patient cohort. A retrospective review was performed at Huddersfield Royal Infirmary using theatre, coding & hip fracture databases. Data was filtered to include patients ≥75, excluding non-femoral injuries. Imaging & notes were then reviewed confirming femoral shaft fractures; excluding open, peri-prosthetic & high energy fractures. Between September 2008 and July 2016 24 patients were identified and split into two equal cohorts, before June 2011 NICE Guidelines and after. The groups were equal in terms of age (Mean: 85.25:84.67, P=0.) & sex (12 females Pre-NICE, 9 Post-Nice, P= 0.22). Our main outcome measures of length of stay were 31.89 days:26 days (p=0.38), time to surgery was 29.8hours: 28.4 hours (p=0.8) and 1-year survival rate conditional odds ratio of 1.48 (p=1.00). A secondary measure demonstrated a significantly higher proportion of post-NICE patients receiving surgery after midday 5/12:11/12 (P= 0.03). The infrequency of low energy femoral shaft fractures makes them difficult to study and production of an adequately powered study in a single centre impossible. The authors hope this work can inspire discussion and a coordinated multicentre approach to answer this question. These patients could easily be treated with the same level of enthusiasm as hip fractures

Background. Peri-prosthetic humerus fractures are relatively uncommon occurrences that can be difficult to manage non-operatively. Locking plate technology has enhanced the surgical management of these fractures. We describe an osteosynthesis technique utilizing a locking plate with eccentrically placed screw holes to place “skive screws” in the proximal end of the plate to achieve fixation around the stem of the implant. Methods. A retrospective review of prospectively collected data was performed for a consecutive series of patients treated with this skive screw technique from May 2011 to September 2014. Seven patients presented with postoperative type B peri-prosthetic humerus fractures. Average follow-up was 24 months. Radiographic analysis was performed on most recent postoperative imaging. Clinical outcomes were assessed using VAS pain, ASES total score, ASES functional score, SST, SANE, range of motion and strength. Results. At an average of follow-up of 24 months, all patients demonstrated fracture healing. Functional outcomes were limited with only two patients achieving forward elevation above 90 degrees and average ASES Function score was 27.5. Pain relief was nearly uniform with an average VAS Pain score of 0.5 (Figure 1). Conclusions. Peri-prosthetic humeral shaft fractures can be successfully treated with hybrid fixation technique using a locking plate with eccentric holes that facilitate placement of proximal “skive screws”. Using this technique, a 100% union rate was observed with excellent pain relief

Fractures of the shaft of the humerus are often treated conservatively in a hanging cast or a humeral brace. The conservative management of this fracture is often prolonged and quite uncomfortable for the patient. Some of the patients will need an operative fixation after a trial of conservative management. We retrospectively looked at 72 consecutive patients with fractures of the shaft of the humerus that presented in our institution over a period of two years. The fracture pattern, treatment modality time to union and the number that needed operative fixation following a trial of conservative treatment was analysed. Of the 72 patients 4 were lost to follow-up. 45 patients had a 1.2.B or 1.2.C type of fracture and 23 had a 1.2.A type of fracture. 29 (41%) were successfully treated conservatively, 11 (16%) patients were operated as the primary procedure and 15 (22%) patients were operated due to delayed or non union. 13 (19%) patients were operated within 4 weeks of the fracture as their alignment was not acceptable on their weekly follow-up. The average time to union in the patients treated conservatively was 22 weeks, while that of the patients treated primarily by open reduction and plating was 14 weeks (p-value<0.05). Patients who needed operation after initial conservative management required prolonged period of rehabilitation and union time was 32.2 weeks. At the time of fracture union 72% of the patients who had been treated conservatively had joint stiffness requiring physiotherapy, while only 18% of those who had an open reduction and internal fixation had stiffness and required physiotherapy. (p-value < 0.05). In conclusion careful consideration should be given before it is decided to treat this fracture conservatively especially in the case of 1.2.A fracture pattern

When fixing a mid or distal periprosthetic femoral fracture with an existing hip replacement, creation of a stress-riser is a significant concern. Our aim was to identify the degree of overlap required to minimise the risk of future fracture between plate and stem. Each fixation scenario was tested using 4th generation composite femoral Sawbones®. Each sawbone was implanted with a collarless polished cemented stem with polymethyl methacrylate bone cement and cement restrictor. 4.5mm broad Peri-loc™ plates were positioned at positions ½, 1 and 2 shaft diameters (SD) proximal and distal to the tip of the femoral stem. Uni-axial strain gauges (medial and lateral longitudinal gauges, anterior and posterior torsional gauges) measured microstrain at tip of the femoral stem with a standard load of 500N in axial, 3-point lateral and composite torsion/posterior loading using an Instron machine. With axial loading fixation with 2SD proximal resulted in the least amount of strain, in both tension & compression, at the tip of the femoral stem. Fixation with 4 unicortical screws was significantly better than 2 alternating unicortical screws (mean microstrain difference 3.9 to 15.3, p<0.0001). With lateral 3-point loading fixation with 2SD proximal overlap and 2 alternating unicortical screws resulted in the least amount of strain, in both tension and compression, at the tip of the femoral stem (p<0.0001). With torsion & posterior displacement 2SD proximal fixation resulted in the least amount of rotational strain. There was no significant difference between 4 unicortical screws compared to 2 alternating unicortical screws (p>0.05 in 3 of 4 gauges). Fixation of midshaft or distal femoral fractures with a well-fixed total hip arthroplasty should have at least 2 shaft diameters of proximal overlap with a 4.5mm broad plate. It is not clear if 4 unicortical screws or 2 alternating screws are optimal

Objectives:. To measure compliance with the Trauma Unit guideline relating to the early application of the Thomas splint in patients with a femur shaft fracture on clinical examination. Design:. Retrospective review of clinical and radiological records of patients presenting from 01 January 2012 to 31 December 2012 at a Level 1 Trauma Unit. Patients:. We included all patients with femur shaft fractures independently of their mechanism of injury. Exclusion criteria were: ipsilateral fracture of the lower limb, neck and supracondylar fractures, pathological, periprosthetic and incomplete fractures. The database available for review included demographic information, mechanism of injury, side injured, surgical procedure and time when a radiological study (Lodox and/or x-ray) was performed. Outcome measures:. Primary outcome measure was the application of a Thomas splint before the first radiological examination was performed. Secondary outcome measure was the increase in patients immobilized with a Thomas splint before their second radiological examination was performed. Results:. We identified 160 fractures, 107 (66.9%) had a femur or pelvis x-ray as the first radiological exam. In 44 (41.1%) of these fractures, a Thomas splint had already been applied. Of the 160 fractures, 53 (33.1%) had a Lodox as first radiological examination. In 16 (30.2%) of these fractures, a Thomas splint had already been applied. The remaining 37 fractures where no Thomas splint was applied prior to the Lodox had been immobilized with either a different type of splint (backslab or Kramer wires) or not immobilized at all. Of these “incorrectly” immobilized or not immobilized fractures, 17 (45.9%) were then correctly immobilized with a Thomas splint prior to the x-ray (x-ray as second radiological exam). Conclusion:. Out of 160 fractures, 60 were immobilized with a Thomas splint prior to the first radiological examination, corresponding to a 37.5% compliance rate with internal guidelines

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

Introduction

Diaphyseal tibial fractures account for approximately 1.9% of adult fractures. Several studies demonstrate a high proportion of diaphyseal tibial fractures have ipsilateral occult posterior malleolus fractures, this ranges from 22–92.3%.

Introduction

Diaphyseal tibial fractures account for approximately 1.9% of adult fractures. Studies have demonstrated a high proportion have ipsilateral occult posterior malleolus fractures. We hypothesize that this rotational element will be highlighted using the Mason & Molloy Classification.
