Aims. Open reduction in developmental dysplasia of the hip (DDH) is regularly performed despite screening programmes, due to failure of treatment or late presentation. A protocol for open reduction of DDH has been refined through collaboration between surgical, anaesthetic, and nursing teams to allow same day discharge. The objective of this study was to determine the safety and feasibility of performing open reduction of DDH as a day case. Methods. A prospectively collected departmental database was visited. All consecutive surgical cases of DDH between June 2015 and March 2020 were collected. Closed reductions, bilateral cases, cases requiring corrective osteotomy, and children with comorbidities were excluded. Data collected included demographics, safety outcome measures (blood loss, complications, readmission, reduction confirmation), and feasibility for discharge according to the Face Legs Activity Cry Consolidability (FLACC) pain scale. A satisfaction questionnaire was filled by the carers. Descriptive statistics were used for analysis. Results. Out of 168 consecutive DDH cases, 16 patients fit the inclusion criteria (age range 10 to 26 months, 13 female). Intraoperative blood loss ranged from "minimal" to 120 ml, and there were no complications or readmissions. The FLACC score was 0 for all patients. The carers satisfaction questionnaire expressed high satisfaction from the experience with adequate information and support provided. Conclusion. Open reduction in DDH, without corrective osteotomy, is safe and feasible to be managed as a day case procedure. It requires a clear treatment pathway, analgesia, sufficient counselling, and communication with carers. It is even more important during the COVID-19 pandemic when reduced length of hospital stay is likely to be safer for both patient and their parents.

Introduction. Developmental dysplasia of the hip (DDH) can be managed through a variety of different surgical approaches from closed reduction to simple tenotomies of the adductors and through to osteotomies of the femur and pelvis. The rate of redislocation following open reduction for the treatment of DDH may be affected by the number of intraoperative surgeons. Materials and methods. We performed a retrospective cohort analysis of 109 patients who underwent open reduction with or without bony osteotomies as a primary intervention between 2013 and 2023. We measured the number of redislocations and number of operating surgeons (either 1 or 2 operating surgeons) to assess for any correlation. 109 patients were identified and corresponded to 121 primary hip operations, the mean age at operation was 82.2 months (range 6 to 739 months). During the 10-year period 7 hip redislocations were identified. Results. Of the 7 redislocated hips, the rate of redislocation was found to be higher in patients who had undergone surgery via a single surgeon (5 redislocations) compared to the dual surgeon cohort (2 redislocations), though this did not reach statistical significance. Redislocation was more common in female patients and right laterality 7.2% and 8.7% respectively, though this again did not reach statistical significance. Conclusions. We conclude that a single surgeon approach, female gender and right laterality are potential risk factors for redislocation following open reduction. Further investigation utilising a larger sample size would be required to appropriately explore these potential risk factors further

Introduction. Ankle fractures in the elderly have been increasing with an ageing but active population and bring with them specific challenges. Medical co-morbidities, a poor soft tissue envelope and a requirement for early mobilisation to prevent morbidity and mortality, all create potential pitfalls to successful treatment. As a result, different techniques have been employed to try and improve outcomes. Total contact casting, both standard and enhanced open reduction internal fixation, external fixation and most recently tibiotalocalcaneal (TTC) nailing have all been proposed as suitable treatment modalities. Over the past five years popular literature has begun to herald TTC nailing as an appropriate and contemporary solution to the complex problem of high-risk ankle fragility fractures. We sought to assess whether, within our patient cohort, the outcomes seen supported the statement that TTC has equal outcomes to more traditional open reduction internal fixation (ORIF) when used to treat the high-risk ankle fragility fracture. Materials & Methods. Results of ORIF versus TTC nailing without joint preparation for treatment of fragility ankle fractures were evaluated via retrospective cohort study of 64 patients with high-risk fragility ankle fractures without our trauma centre. We aimed to assess whether results within our unit were equal to those seen within other published studies. Patients were matched 1:1 based on gender, age, Charlson Comorbidity Index (CCI) and ASA score. Patient demographics, AO/OTA fracture classification, intra-operative and post-operative complications, discharge destination, union rates, FADI scores and patient mobility were recorded. Results. There were 32 patients within each arm. Mean age was 78.4 (TTC) and 78.3 (ORIF). The CCI was 5.9 in each group respectively with mean ASA 2.9 (TTC) and 2.8 (ORIF). There were two open fractures within each group. Median follow up duration was 26 months. Time to theatre from injury was 8.0 days (TTC) versus 3.3 days (ORIF). There was no statistically significant difference in 30-day, one year or overall mortality at final follow up. Kaplan-Meier survivorship analysis did however demonstrate that of those patients who died post-operatively the mean time to mortality was significantly shorter in those treated with TTC nailing versus ORIF (20.3 months versus 38.2 months, p=0.013). There was no statistical difference in the overall complication rate between the two groups (46.9% versus 25%, p=0.12). The re-operation rate was twice as high in patients treated with TTC nailing however this was not statistically significant. There was no statistical difference in the FADI scores at final follow up, 72.1±12.9 (TTC) versus 67.9±13.9 (ORIF) nor post-operative mobility status. Conclusions. Within our study TTC nailing with an unprepared joint demonstrated broadly equivalent results to ORIF in the management of high-risk ankle fragility fractures; this replicates findings of previous studies. We did however observe that mean survival was significantly shorter in the TTC group than those treated with ORIF. We believe this may have been contributed to by a delay to theatre due to TTC stabilisation being treated as a sub-specialist operation in our unit at the time. We propose that both TTC and ORIF are satisfactory techniques to stabilise the frail ankle fracture however, similarly to the other fragility fractures, the priority should be on an emergent operation in a timely fashion in order to minimise the associated morbidity and mortality. Further randomised control studies are needed within the area to establish definitive results and a working consensus

Introduction: The incidence of DDH has decreased dramatically during the last thirty years. The first reason was the introduction of targeted examination of all newborn babies (in the Czech Republic since 1977) and then our system was adopted by all of the other European countries. In the 1960s about 15% of all children were treated for different stages of hip dysplasia and there were 3% of true dislocations. These very high numbers of less serious grades of DDH are partially due to over-diagnosis and over-treatment. In the 1980s, the numbers had been reduced to 5% of dysplasias and 0.8% of dislocations. The introduction of ultrasound examination according to Graf within the first week of life has contributed to further reduction of DDH cases. Material and Methods: Open reduction is indicated only for congenitally dislocated hip joints in which tender, conservative reduction cannot be done. As a tender reduction, this can only be made by continuous overhead traction with a gradual increase of hip abduction from 10 to 60 degrees. When reduction cannot be considered as harmless, the surgical procedure consisting of open reduction and derotational osteotomy should be performed before the age of one year. In children older than the age of eighteen months a pelvic osteotomy must be added. Results: From 1980 to the end of 2000 (a period of 21 years), 147 dislocated hip joints in 128 children were operatively treated. The average follow-up was 11 years (2 – 21). In the age group of up to 15 months of age, 68 hip joints (62 patients) had open reduction and a derotational osteotomy was added in 32 cases (47%). An additional pelvic osteotomy in cases of simple open reduction was performed on 17 hips (47%) and on 10 hips (31%) in cases of open reduction and derotation. Aseptic necrosis developed in 5 cases (7.3%), but it is difficult to distinguish between pre-existing necrosis after conservative treatment and postoperative necrosis. In the age group of 15 months to 36 months, there were 47 hip joints in 42 children. The surgery consisted of open reduction, varus and derotational osteotomy plus Salter (exceptionally Pemberton) osteotomy. The rate of necrosis was 12.8% (6 cases). The open reduction in children older than the age of 3 was performed in 24 children (32 hip joints). The open reduction, varus and derotational osteotomy of the femur were performed in all cases. The Salter osteotomy was performed in 12 hips, Pemberton in 5, triple pelvic osteotomy in 6 cases, and Chiari was used in primary reduction in 9 cases. The necrosis rate was 6.2% (2 cases). In the targeted study regarding the effectivity of overhead traction, we had 90 hip joints in 76 patients. In the group of primary treatment in our institution (57 hip joints), successful reduction was reached in 80.1% of cases, but in the group of 33 hip joints where primary treatment had failed, conservative treatment was successful in only 30% and open reduction was performed in 23 cases. We used the radiological classification according to Severin and clinical score according to Merle D’Aubigne: Severin I - excellent results − 12%, Severin II – good – 63%, Severin III – fair – 15%, Severin IV – poor – 6%, Severin V – re-dislocation, 6 cases – 4%. The necrosis rate was 9%. Conclusion: Conservative and operative treatment of DDH are not two competing methods. The treatment of each dislocation starts conservatively. Only when there is no chance for harmless, tender reduction of the femoral head into the acetabular socket, the open reduction should be indicated and performed by experienced specialists. Early open reduction with femoral derotation gives statistically significant better results in comparison with only open reduction. The percentage of excellent results seems to be low, but it must be kept in mind that a hip joint which was operated and had an open reduction heals, in the majority of cases, at least radiologically. Functional results do not correspond in childhood with the radiology. Despite that, the children in the time period of FU do not complain, and the patients with operated DDH in the natural history must be considered as a high risk for the development of secondary coxarthrosis

Abstract. Background. The incidence of periprosthetic fractures of the femur around a total knee arthroplasty (TKA) is rising and this is owed to the increased longevity that today's TKA implants allow for, as well as an aging population. These injuries are significant as they are related to increased morbidity and mortality. Methods. We retrospectively reviewed all periprosthetic fractures around a TKA that presented to our NHS Trust between 2011 to 2020. Medical records were reviewed. Treatment, complications and mortality were noted. Results. 37 patients (34 females) with an average age of 84 (range 65–99) met the inclusion criteria for this study. 17 patients (45.9%) underwent open reduction and internal fixation (ORIF), eight patients (21.6%) underwent revision arthroplasty to a distal femoral replacement (DFR) and 12 patients (32.4%) were treated non-operatively. 10 (58.8%) of the 17 patients that were treated with ORIF were discharged from hospital to a rehabilitation facility rather than their usual residence. In comparison, 3 (37.5%) of the patients that were treated with a DFR were discharged to a rehabilitation facility. one-year mortality rate in the ORIF group was 29.4 compared to 12.5% in those that had a DFR. Conclusion. Revision arthroplasty using a DFR should be considered in patients with periprosthetic fractures around a TKR, as it is associated with lower mortality rates and higher immediate post-operative function

Background. Studies have compared open reduction internal fixation (ORIF) with fibular nail fixation (FNF) and shown reduced wound complications with minimal difference to PROMS in the short term. Our aim is to compare long-term outcomes for unstable ankle fractures at 10 year follow up. Methods. Patients from a previously conducted RCT were contacted at a minimum of 10 years post intervention at a single study centre. Case notes were reviewed, and patient reported outcome measures acquired at 10 years. Results. Ninety-nine patients were included (48 FNF and 51 ORIF). After 10 years 75% (33/44) of patients in the FNF group required no further follow up versus 81% (39/48) in the ORIF group. Radiographically at 2 years post-injury, there was no statistically significant difference between groups for development of osteoarthritis (p=0.851). There was one tibio-talar fusion in each group secondary to osteoarthritis, but no statistically significant difference in overall re-operation rate (p=0.518). Fifty-one percent (n=50) of patients have so far returned patient reported outcome measures at a minimum of 10 years (Fibular nail n=23, plate fixation n=27). No significant difference was found between groups for the mean scores of Olerud and Molander Ankle Score (FNF 84.78 vs ORIF 84.07; p=0.883), the Manchester-Oxford Foot Questionnaire (MOXFQ) (FNF 89.54 vs ORIF 96.47; p=0.112), Euroqol-5D Index (FNF 0.88 vs ORIF 0.87; p=0.701) and Euroqol-5D Visual Analogue Score (FNF 77.30 vs ORIF 77.52; p=0.859). Conclusion. The current study illustrates that both methods of treatment result in a satisfactory long-term outcome with no difference in late complications or PROM scores at up to 10 years in patients under 65 years old, although the study is currently under powered

The risk of AVN is high in Unstable Slipped Capital Femoral Epiphysis (SCFE) and the optimal surgical treatment remains controversial. Our AVN rates in severe, unstable SCFE remained unchanged following the introduction of the Modified Dunn Procedure (MDP) and as a result, our practice evolved towards performing an Anterior Open Reduction and Decompression (AOR) in an attempt to potentially reduce the “second hit” phenomenon that may contribute. The aim of this study was to determine the early surgical outcomes in Unstable SCFE following AOR compared to the MDP. All moderate to severe, Loder unstable SCFEs between 2008 and 2022 undergoing either an AOR or MDP were included. AVN was defined as a non-viable post-operative SPECT-CT scan. Eighteen patients who underwent AOR and 100 who underwent MPD were included. There was no significant difference in severity (mean PSA 64 vs 66 degrees, p = 0.641), or delay to surgery (p = 0.973) between each group. There was no significant difference in the AVN rate at 27.8% compared to 24% in the AOR and MDP groups respectively (p = 0.732). The mean operative time in the AOR group was 24 minutes less, however this was not statistically significant (p = 0.084). The post-reduction PSA was 26 degrees (range, 13–39) in the AOR group and 9 degrees (range, -7 to 29) in the MDP group (p<0.001). Intra-operative femoral head monitoring had a lower positive predictive value in the AOR group (71% compared to 90%). Preliminary results suggest the AVN rate is not significantly different following AOR. There is less of an associated learning curve with the AOR, but as anticipated, a less anatomical reduction was achieved in this group. We still feel that there is a role for the MDP in unstable slips with a larger remodelling component

Purpose: To compare the incidence of avascular necrosis, and radiological outcomes between groups treated by closed reduction, open reduction, and open reduction + femoral shortening, under the care of a single surgeon, with open reductions performed through an anterior approach, uninfluenced by the appearance of the ossific nucleus. Methods: Between Sept 1991 and Dec 2003 we retrospectively studied 66 patients (3 bilateral; 10 males, 53 females) who had undergone reduction under anaesthesia. Of these 34 hips were reduced closed with adductor release (average 0.7 yrs, range 0.2–1.7), 11 reduced open (average age 1.0; 0.4–3.3) and 24 reduced open with femoral shortening (average age 2.4; 0.9–7.8). Follow up radiographs were graded for the presence of AVN by the Bucholz and Ogden method. Radiological outcome was graded by the Severin score. Average follow up was up to the age of 6.6 years (SD 2.9) for the closed reduction group, open reduction group 8.0 (SD 3.6) and femoral shortening group 9.0 (SD 3.9). Results:. AVN scores. Closed Reduction (n=34) : Grade 1 : 5. Open Reduction (n= 11) : Grade 1: 2, Grade 2: 1, Grade 3: 1. Open, with shortening (n=24): Grade 1: 5, Grade 2: 1. Severin Scores:. Closed I: 22 II:3 III:8 IV:0. Open I:6 II:1 III:2 IV:2. Shortening I: 8 II:8 III:3 IV:2. Conclusions: The group with the highest incidence of AVN & worse Severin grades was the group (average age-1.0) who had open reduction without femoral shortening. The open reduction & shortening group had a higher proportion of good radiological results despite treatment being given at a older age. Concentric closed reduction, where possible, gave the best results. Significance: Any child presenting with DDH at walking age (over 1) who requires open reduction should also have a femoral shortening. This gives the best chance of avoiding high grade AVN and achieving a good radiological result. Results might improve if open reductions without shortening were discontinued

Background. Sub-trochanteric fractures are challenging to treat due to various anatomical and biomechanical factors. High tensile forces contribute to the challenge of fracture reduction. Intramedullary nailing has become the treatment of choice. If anatomical reduction is not achieved, any mal-alignment will predispose to implant failure. Open reduction with cerclage wires can add to construct stability and improve the quality of reduction. There is no consensus or classification to guide surgeons on when to perform open reduction, which is often performed intra-operatively when closed reduction fails often with no planning. This can lead to intraoperative delays as theatre staff would not have prepared the correct equipment necessary for open reduction. Objectives. The purpose of this study was to assess outcomes of closed and open reduction of traumatic sub-trochanteric fractures treated with intramedullary nailing and to propose a new classification system to dictate management. Methods. After a review of current classification systems, a 3-tier classification was proposed (Type 1, 2 and 3). Type 1 indicated a transverse fracture, Type 2 was a spiral fracture with an intact posterior and medial wall and a Type 3 fracture were fractures with no posterior and/or medial walls. Over a two-year period (2013–2015), patients with sub trochanteric fractures were classified into Type 1, 2 or 3 injuries based on radiographic appearances by two senior clinicians. Patients with Type 3 injuries were divided into two groups based on whether they were treated with open or closed reduction. A clinical and radiographic review was performed. The primary outcome measure was the incidence of implant failure, whereas secondary outcome measures were related to fracture reduction. Statistical analysis was performed using GraphPad Prism Version 6 (GraphPad Software Inc. California, USA). Fisher's exact test was used for independent categorical data and Mann–U Whitney for continuous nonparametric data. Statistical significance was set at p<0.05. Results. 75 patients had intramedullary nailing for subtrochanteric fractures over the study period with a mean age of 82.6 years. There were 48 patients who had a Type 3 fracture pattern with a deficient medial and/or posterior wall. Reduction was achieved open with cerclage wires in 42% of patients (n=20 and closed in 58% (n=28). Overall there were a total of 18 (37.5%) major complications. In patients treated with closed reduction, 9 patients suffered mechanical complications (6 distal locking screw failures, 3 lag screw cut outs). There was a significantly increased risk of implant failure in patients treated with closed reduction compared to open reduction (p=0.006). No cases with cerclage wire had implant failure. Open reduction with cerclage wires improved the quality of reduction (p=0.0001) compared with closed reduction. There was no significant increase in operating time in patients treated with cerclage wires (p=0.4334). Conclusions. Open reduction with cerclage wires should be considered in patients with Type 3 sub-trochanteric fractures as it has shown to significantly reduce the risk of implant failure and improve the quality of reduction with no significant increase in operating time

Management of acetabular fractures in the elderly population remains somewhat controversial in regards to when to consider is open reduction internal fixation (ORIF) versus acute primary total hip. study aims to (1) describe outcome of this complex problem and investigate predictors of successful outcome. This retrospective study analyzes all acetabular fractures in patients over the age of 60, managed by ORIF at a tertiary trauma care centre between 2007 and 2018 with a minimum follow up of one year. Of the 117 patients reviewed, 85 patients undergoing ORIF for treatment of their acetabular fracture were included in the analysis. The remainder were excluded based management option including acute ORIF with THA (n=10), two-stage ORIF (n=2), external fixator only (n=1), acute THA (n=1), and conservative management (n=1). The remainder were excluded based on inaccessible medical records (n=6), mislabelled diagnosis (n=6), associated femoral injuries (n=4), acetabular fracture following hemiarthroplasty (n=1). The mean age of the cohort is 70±7 years old with 74% (n=62) of patients being male. Data collected included: demographics, mechanism of injury, Charlson Comorbidity Index (CCI), ASA Grade, smoking status and reoperations. Pre-Operative Radiographs were analyzed to determine the Judet and Letournel fracture pattern, presence of comminution and posterior wall marginal impaction. Postoperative radiographs were used to determine Matta Grade of Reduction. Outcome measures included morbidity-, mortality- rates, joint survival, radiographic evidence of osteoarthritis and patient reported outcome measures (PROMs) using the Oxford Hip Score (OHS) at follow-up. A poor outcome in ORIF was defined as one of the following: 1) conversion to THA or 2) the presence of radiographic OA, combined with an OHS less than 34 (findings consistent with a hip that would benefit from a hip replacement). The data was analyzed step-wise to create a regression model predictive of outcome following ORIF. Following ORIF, 31% (n=26) of the cohort had anatomic reduction, while 64% (n=54) had imperfect or poor reduction. 4 patients did not have adequate postoperative radiographs to assess the reduction. 31 of 84 patients undergoing ORIF had a complication of which 22.6% (n=19) required reoperation. The most common reason being conversion to THA (n=14), which occurred an average of 1.6±1.9 years post-ORIF. The remainder required reoperation for infection (n=5). Including those converted to THA, 43% (n=36) developed radiographic OA following acetabular fracture management. The mean OHS in patients undergoing ORIF was 36 ± 10; 13(16%) had an OHS less than 34. The results of the logistic regression demonstrate that Matta grade of reduction (p=0.017), to be predictive of a poor outcome in acetabular fracture management. With non-anatomic alignment following fixation, patients had a 3 times greater risk of a poor outcome. No other variables were found to be predictive of ORIF outcome. The ability to achieve anatomic reduction of fracture fragments as determined by the Matta grade, is predictive of the ability to retain the native hip with acceptable outcome following acetabular fracture in the elderly. Further research must be conducted to determine predictors of adequate reduction in order to identify candidates for ORIF

Lisfranc injuries are uncommon and can be challenging to manage. There is considerable variation in opinion regarding the mode of operative treatment of these injuries, with some studies preferring primary arthrodesis over traditional open reduction and internal fixation (ORIF). We aim to assess the clinical and radiological outcomes of the patients treated with ORIF in our unit. This is a retrospective study, in which all 27 consecutive patients treated with ORIF between June 2013 and October 2018 by one surgeon were included with an average follow-up of 2.4 years. All patients underwent ORIF with joint-sparing surgery by a dorsal bridging plate (DBP) for the second and third tarsometatarsal (TMT) joint, and the first TMT joint was fixed with trans-articular screws. Patients had clinical examination and radiological assessment, and completed American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Foot Function Index (FFI) questionnaires. Our early results of 22 patients (5 lost to follow-up) showed that 16 (72%) patients were pain free, walking normally without aids, and wearing normal shoes and 68% were able to run or play sports. The mean AOFAS midfoot score was 78.1 (63–100) and the average FFI was 19.5 (0.6–34). Radiological assessment confirmed that only three patients had progression to posttraumatic arthritis at the TMT joints though only one of these was clinically symptomatic. Good clinical and radiological outcomes can be achieved by ORIF in Lisfranc injuries with joint-sparing surgery using DBP

Purpose of the study. This study aims to evaluate the use of closed reduction of hips with developmental dysplasia of the hip (DDH) and medial open reduction of these hips as a subsection of closed reduced hips. Methods. The study was a retrospective analysis of treatment of 30 children with developmental dysplasia of the hip (DDH). These children were taken from a consecutive series of children treated over a period from June 2000 to 2011 with closed reduction by a single surgeon. The ages at the time of diagnosis were between 1 day and 13 months (mean 5.25 weeks). Included in this series are 7 patients treated with medial open reduction, all done with the Ludloff approach. Follow up of these patients was from 8 months to 12 years (mean 5 years). All patients needing secondary procedures were noted. The X- rays were evaluated for percentage acetabulum cover in patients over the age of 8 and improvement of the acetabular index in all these patients. Results. 4 children needed secondary procedures. 1 child of the closed reduction group developed avascular necrosis of the femoral head that was treated with a Salter osteotomy and a further 2 needed secondary open reductions after redislocation following initial closed reduction. One child with bilateral open medial reductions had a Salter osteotomy 6 years after the initial treatment was done. 26 of the children had good outcomes with improvement of the acetabular angles, percentage acetabular cover and pain free independent ambulation. The average acetabular index improved from 37.5° to 23.3°. Conclusion. Closed reduction of DDH hips is a good treatment modality. Early treatment allows for acetabular and femoral development. There are minimal secondary procedures necessary after closed reduction, and open medial reduction does not increase the complication rate. NO DISCLOSURES

Avascular necrosis (AVN) of the femoral head is a potentially devastating complication of treatment for developmental dysplasia of the hip (DDH). AVN most commonly occurs following operative management by closed (CR) or open reduction (OR). This occurrence has frequently been examined in single centre, retrospective studies, however, little high-level evidence exists to provide insight on potential risk factors. The purpose of this observational, prospective multi-centre study was to identify predictors of AVN following operatively-managed DDH. A multi-centre, prospective database of infants diagnosed with DDH from 0–18 months was analyzed for patients treated by CR and/or OR. At minimum one year follow-up, the incidence of AVN (Salter criteria) was determined from AP pelvis radiographs via blinded assessment and consensus discussion between three senior paediatric orthopaedic surgeons. Patient demographics, clinical exam findings and radiographic data were assessed for potential predictors of AVN. A total of 139 hips in 125 patients (102 female, 23 male) underwent CR/OR at a median age of 10.4 months (range 0.7–27.9). AVN was identified in 37 cases (26.6% incidence) at a median 23 months post-surgery. Univariate logistic regression analysis comparing AVN and no AVN groups identified sex, age at diagnosis, age at surgery, pre-surgery IHDI grade and time between diagnosis and surgery as potential predictive factors. Specifically, male sex (OR 2.21 [0.87,5.72]), IHDI grade IV, and older age at diagnosis (7.4 vs. 9.5 months) and surgery (10.2 vs. 13.6 months) were associated with development of AVN. Likewise, increased time between diagnosis and surgery (2.9 vs. 5.5 months) was also associated with a higher incidence. No association was found with surgery type (CR vs. OR), pre-surgery acetabular index or surgical hip. Development of AVN occurred in 26.6% of hips undergoing CR or OR at a median 23 months post-surgery. Male sex, older age at diagnosis and surgery, dislocation severity and increased time between diagnosis and surgery were associated with AVN. Longer-term follow-up and larger numbers will be required to confirm these findings. Early outcomes from this prospective patient cohort suggest that AVN is an important complication of operative management for DDH, and appears to occur at a comparable rate whether the reduction is performed open or closed. Male patients may be more susceptible to developing AVN and merits further exploration. Potential predictive factors of older age and length of time between diagnosis and surgery emphasize the importance of early detection and treatment to minimize complications and optimize outcomes

To compare the clinical and radiographic outcomes of Type III supracondylar fractures of the humerus in children managed either by open reduction and internal fixation versus those treated by closed reduction and percutaneous pinning. The indications for open reduction included an inability to obtain a satisfactory reduction by closed means; open fractures and fractures with vascular compromise after closed reduction. Retrospective chart and radiograph review over a ten year period (1995–2005), with two hundred and thirty-six children with Type III fractures treated at a Level One pediatric hospital within a universal health-care system. One hundred and seventy by closed reduction and percutaneous pinning and sixty-six by open reduction. The left arm was involved in one hundred and forty-eight cases and twenty-five patients had vascular compromise at presentation but no cases required vascular repair. There were ten open fractures in the open reduction group. The anterior approach was employed in twenty-nine patients, anteromedial in twenty-two and anterolateral, medial and lateral in equal preference. Entrapped structures included brachialis muscle in thirty-four patients, periosteum in eighteen, radial nerve in two, medial nerve in two, and the brachial artery in one. According to Flynn’s criteria, the open reduction group had an excellent or good outcome in 90% of cases while the closed reduction group had an 80% excellent or good outcome. In this study of displaced Type III supracondylar fractures, there was a higher rate of open reduction than was initially anticipated. There was a higher rate of excellent and good outcomes in the ORIF group but this may be due to a relatively short follow-up in the closed reduction group. Post reduction stiffness would likely dissipate and allow a higher rate of excellent and good outcomes in the closed reduction group. An anterior approach or variation of an anterior approach is best suited to visualise the anatomy and structures hindering the reduction. Despite this, there was no clinical or radiographic difference between the approaches employed. In conclusion, open reduction and internal fixation if displaced Type III supracondylar fractures is a safe and effective procedure. An anterior approach is recommended to identify and relieve the soft tissue obstacles to a suitable reduction. Significance: This study furthers the literature that proposes to lower the threshold for open versus closed reduction of displaced supercondylar fractures in children

Aim. The objective was to assess whether late presentation of DDH leads to an increase in treatment magnitude and cost. Method. This was a retrospective review of prospectively collected data from our hip instability clinic database. All patients presenting to our hip instability clinic that required any form of treatment for DDH between 1990 and 2005 were included. Children were grouped according to age at presentation and then treatment requirements were reviewed. Average costs were calculated based on procedures performed. Results. 84% of children presenting before 6 weeks were treated successfully with abduction bracing, versus none after the age of 10 months. The need for open reduction increased from 8% if presenting before 6 weeks to 86% for those over 10 months. This equates to a 12-fold increase in relative risk of requiring open reduction surgery. Increasing age at presentation was associated with an increase in the number of procedures required, increased magnitude of procedure and increased financial cost per patient. Conclusion. The loss of repeated screening for DDH will lead to an increase in late presentations. This work has demonstrated that increased age of presentation leads to a concomitant increase in open reduction and other operative procedures. Implementation of an additional opportunistic mandatory screening examination at 3–5 months could help to reduce the unintended effects of the new guidelines

Background. Outcome of Type II and III (Sander's CT classification) fracture of the calcaneum who underwent open reduction and internal fixation was assessed. Methods. Thirty-three type II and III fractures of the calcaneum (all unilateral) underwent open reduction and internal fixation using the ‘extensile lateral approach’. There were twelve Type II and twenty-one Type III fractures. Patients were followed up for a mean of 40.81 months (Range 28 to 62 months). Patients were assessed clinically by the Creighton Nebraska Health foundation score for assessment of fractures of the calcaneum. Radiologically assessment was done comparing the pre and post operativeBohler's and Gissane angles and measuring the calcaneal width on the axial xrays. Results. Nineteen patient were classified as excellent and 14 as good. There were no poor or fair results. The mean correction of Bohler's angle was 5.6 +/− 7.2 and the Gissane'sanglecorrected by 7.8 +/−5.8 °. Superficial skin necrosis was the most common complication encountered (3 patients). Two patients preferred removal of the implant after fracture union due to prominent hardware. Conclusion. Open reduction Type II and III intra – articular calcaneal fractures is associated with minimal complications and gives reproducible results, especially in young adults

Introduction. Intraarticular calcaneal fractures often need open reduction and internal fixation (ORIF) with plate osteosynthesis. The wound complication is one of the common problems encountered following this and affects the outcome adversely. Our study was done to assess how far postoperative slab/cast can avert wound complications. Methods. Out of 42 patients with unilateral intraarticular calcaneal fractures, 20 were offered postoperative slab/cast and this was continued for six weeks. The remaining 22 patients were not offered any plaster. All patients were followed-up for two years. Results. The incidence of wound dehiscence was 2 in the plaster group as well as 8 in the non-plaster group and this was statistically significant (p = 0.02). Also, significantly lower heel widening was reported in the plaster group (p = 0.03). Although, there was no significant difference in the patient-reported outcome (Maryland Foot Score) and the incidence of pain between the two groups, the occurrence of neurological deficit following surgery and the postoperative range of movements were comparable in these two groups. Conclusion. Thus, it may be concluded that postoperative plaster application for the initial six weeks could be a low-cost yet effective way to reduce wound complications following plate osteosynthesis in intraarticular calcaneal fractures

Abstract. Objective. To compare the clinical and radiological outcome between less invasive stabilization system (LISS, Synthes, Paoli, PA.) and open reduction with internal fixation (ORIF) for the treatment of extraarticular proximal tibia fractures through the lateral approach. Background. Proximal tibial fractures present a difficult treatment challenge with historically high complication rates. ORIF has been in vogue for long time with good outcome. But these are associated with problems especially overlying skin conditions, delayed recovery and rehabilitation with limited functional outcome. LISS is an emerging procedure for the treatment of proximal tibial fractures. It preserves soft tissue and the periosteal circulation, which promotes fracture healing. Patients and methods. Thirty patients with closed proximal tibial fractures were included in this study. They were randomly divided into 2 groups. Group I (n=15) patients were treated by LISS and group II (n=15) by ORIF. Major characteristics of the two groups were similar in terms of age, sex, mode of injury, fracture location, and associated injuries. All patients were followed up at least 6 months. Results. In each group, 12 patients were united, 2 patients were non- united and one patient showed delayed union. The mean operative time in LISS patients was 79.3 min, while in ORIF patients; it was 122 min. All patients of LISS group were exposed to radiation, while only 40% of ORIF group were exposed. The mean time of union of LISS patients was 10.87weeks. While in ORIF patients, the mean time of union was 21.13 weeks. There was no significant difference between both groups regarding the postoperative complications. Functional outcome was satisfactory in both groups. Conclusion. LISS achieves comparable results with ORIF in extraarticular fractures of the proximal tibia. Although LISS potentially has the radiation hazard, it reduces the perioperative complications with a shortened operation time and minimal soft tissue dissection. Declaration of Interest.

Aim. To compare the rate and severity of avascular necrosis following medial open and closed reduction in developmental hip dysplasia and the resulting influence on femoral and acetabular development. Method. The radiographs and hospital records of 118 patients with dislocation of the hip were reviewed. 57 patients (66 hips) underwent medial open reduction and 61 patients (75 hips) underwent closed reduction. Mean follow-up was 10.9 years (5 years to 17.4 years). Avascular necrosis (AVN) was recorded according to the Bucholz and Ogden classification. The acetabular index was measured pre-operatively, at 1 and 4 years following surgery. The final radiograph was assigned a Severin grade. Sharp and centre-edge angles were recorded at final follow-up. A Severin grade I or II was considered a satisfactory result and a grade III to V an unsatisfactory result. Initial non-operative measures, such as Pavlik harness treatment and traction were documented. Additional surgical interventions were noted. Results. The rate of clinically significant AVN (types 2, 3, 4) following medial open reduction was 28.7% versus 17.3% following closed reduction. The rate of Type 2 AVN was 22.7% versus 10.6% respectively. Early acetabular development was similar in both groups. Long-term follow-up showed an unsatisfactory outcome (Severin grade III-V) following medial open reduction in 32% versus 8% in the closed reduction group. Conclusion. Our findings suggest that medial open reduction is associated with a higher rate of AVN than closed reduction. Type 2 AVN was twice as common in the medial open reduction group. More unsatisfactory results were seen in the medial open reduction group at long term follow up

Open reduction and internal fixation (ORIF) with trans-articular screws or dorsal plating is the standard surgical technique for displaced Lisfranc injuries. This aim of this study is to compare the clinical outcomes of percutaneous reduction and internal fixation (PRIF) of low energy Lisfranc injuries with a matched, control group of patients treated with ORIF. Over a seven-year period (2012–2019), 16 consecutive patients with a low energy Myerson B2-type injury were treated with PRIF. Patient demographics were recorded within a prospectively maintained database at the institution. This study sample was matched for age, sex and mechanism of injury to a control group of 16 patients with similar Myerson B2-type injuries treated with ORIF. Clinical outcome was compared using the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Manchester Oxford Foot Questionnaire (MOXFQ). At a mean follow up of 43.0 months (95% CI 35.6 – 50.4), both the AOFAS and MOXFQ scores were significantly higher in the PRIF group compared to the control ORIF group (AOFAS 89.1vs 76.4, p=0.03; MOXFQ 10.0 vs 27.6, p=0.03). There were no immediate postoperative complications in either group. At final follow up, there was no radiological evidence of midfoot osteoarthritis in any patient in the PRIF group. Three patients in the ORIF group developed midfoot osteoarthritis, one of whom required midfoot fusion. PRIF is a technically simple, less invasive method of operative stabilisation of low energy Lisfranc injures which also appears to be associated with better mid-term clinical outcomes compared to ORIF
