Aim and objective: To study the radiological and functional outcomes as well as complications in the management of fractures involving both columns of the acetabulum using a single surgical approach.

Design: Type IV, prospective clinical study.

Setting: Level I trauma centre.

Materials and methods: Inclusion criteria were as follows: (a) patients over 20 year of age and (b) patients suffering from acetabular fractures involving both columns as per Letournel and Judet classification, namely transverse, transverse + posterior wall, T type, anterior column posterior hemi-transverse (ACPHT) and associated both columns. Exclusion criteria were as follows: (a) patient suffering from isolated anterior column, posterior column, anterior wall, posterior wall and posterior wall + column fractures; (b) patient who have undergone surgical procedures of the hip prior to trauma; and (c) compound acetabular fractures. A total of 23 patients having both column acetabulum fractures were included prospectively from June 2016 to December 2018 and followed up till 1 year postoperatively. Open reduction and internal fixation were performed through one of three described approaches, i.e., iliofemoral, Kocher-Langenbeck, and anterior intrapelvic or ilioinguinal.

Results: Our study population consisted of 30.4% transverse, 39.1% associated both columns, 21.7% T type and 8.7% anterior column + posterior hemi-transverse. Of these, 65.2% were operated using the Kocher-Langenbeck approach, while 30.4% of patients required the anterior intrapelvic approach. The remaining 4.3% of patients were operated by the iliofemoral approach. Anatomic reduction was achieved in 100% of our study population with remaining displacement less than or equal to 1°mm. At 1-year follow-up, all fractures showed a satisfactory union with an excellent Matta index in 100% study subjects. Complications at 1 year included one case of foot drop, which was present preoperatively but failed to improve and one case of post-traumatic arthritis. Average Harris Hip score (HHS) and mean Merle D'Aubigne (MDA) scores suggested good clinical outcomes in the study population.

Conclusions: A single approach can be used to achieve good functional and radiological outcomes in carefully selected bicolumnar fractures of the acetabulum, with less approach-related morbidity.

Clinical significance: Traditionally, multiple approaches are used for acetabulum fractures involving both columns, but with proper patient selection, single approach can be used with good functional and surgical outcomes.

Aim and objective: Software-guided realignment is proposed as an easy and accurate method of achieving simultaneous multiaxial correction. The accuracy and efficacy in periarticular problems have not been investigated fully. This study investigates the results and possible clinical benefits.

Materials and methods: A retrospective review was performed in 24 patients with 27 periarticular deformities of the lower limb treated by the Ilizarov technique. Bony realignment was achieved by a software-guided hexapod realignment device. The deformity category, deformity severity score (DSS) and individual deformity component scores were measured for objective quantification of each deformity. The periarticular level, number of manoeuvres, correction period and any difficulties in the execution of the correction manoeuvre were noted. Pre-procedure and post-procedure values of deformity parameters were analysed to estimate the accuracy and efficacy of the realignment device.

Results: The correction manoeuvre was accomplished successfully in all patients except two. The mean correction period was 14.9 days (range, 5-38 days). The mean pre-procedure DSS was 18.7 (range 6.3-27.3), which reduced to a mean post-procedure value of 1.5 (range, 0-7.9) with a 92.0% deformity correction (p-value < 0.001)). There was a significant reversal of individual deformity components. DSS values were achieved to an excellent level (< 3.5) in 25 deformities and to good and poor levels in one deformity, respectively.

Conclusion: Software-guided realignments are effective for accurate realignment of periarticular deformities using Ilizarov fixators. These devices offer simultaneous multidimensional corrections even in complex multiplanar deformities and simplify the task of deformity correction.

Clinical significance: The present study assesses the accuracy and efficacy of software-guided realignments using novel concepts of deformity category, DSS and individual deformity component scores, which may overcome some of the shortcomings of conventional assessment methods.

Aims and objectives: To examine clinical and functional outcomes in patients with intra- and extra-articular distal tibial fractures treated definitively by Ilizarov fixation.

Materials and methods: Patients with tibial fractures extending within 1 Müller square of the ankle joint were identified from our Ilizarov database over a 5-year period. Data on treatment and outcome were assembled from this database and supplemented by a review of patient records. General measures of health-related quality of life and limb-specific functional outcome scores were recorded. Adverse events were documented according to Paley's classification.

Results: One hundred and sixty-eight patients with 169 fractures were identified, 28% were open and 63% intra-articular. One hundred and sixty-five (98%) of the fractures united, two following bone grafting in their original frames, at a median of 166.5 days (range 104-537). Three patients with nonunions united with further treatment. One patient (an end-stage diabetic) elected to undergo amputation following multiple early complications during treatment. Closed fractures united more rapidly than open (median 157 vs 183 days; p = 0.005) and true Pilon (43C3) fractures took longer to unite than other fractures (median 157 vs 177 days; p = 0.01).Sixty-seven percent of patients completed functional outcome scores. Sixty-two percent reported good or excellent ankle scores at more than 6 months post frame removal, 38% fair and 10% poor. Patients with intra-articular fractures reported significantly worse ankle scores than those with extra-articular injuries. General measures of health-related quality of life (EuroQol-5D) revealed significant ongoing effects despite good clinical outcomes.

Conclusion: This study demonstrates a high union and low serious complication rate, suggesting that external ring fixation is a safe and effective treatment for these injuries.

Charcot arthropathy related foot and ankle deformities are a serious challenge. Surgical treatment of these deformities is now well established. Conventional surgical treatment includes extensive surgical exposure, excision of bone, acute correction and internal fixation, which is not always appropriate in presence of active ulceration, infection and poor bone quality. A minimally invasive approach to osteotomies and gradual correction of deformities using a circular frame are proving helpful in minimizing the complications. Taylor Spatial Frame (TSF) hexapod with its various modules is well suited for a range of foot and ankle deformities. We have advocated minimally invasive targeted hind and mid foot osteotomies and gradual correction with Taylor Spatial Frame (TSF) in 10 patients with recurrent ulceration and deformity. There are 2 female and 8 male patients in this cohort. Appropriate TSF module was chosen for each patient- a long bone module for ankle and hindfoot deformities (4 patients) and a forefoot 6x6 butt frame (6 patients) for foot deformities. An osteotomy through the midfoot was performed in all chronic stable foot deformity cases. In the ankle and hindfoot deformities, a combination of soft tissue distraction correction of equinus and acute correction of hindfoot deformity through a calcaneal osteotomy, were used. Our outcome measures are complete healing of the ulcers and resolution of infection, clinically plantigrade foot and ability to wear regular or diabetic footwear. Complications included eight episodes of pin infection that responded to oral antibiotics only and two pin breakages. We achieved ulcer and infection free plantigrade feet that fit in to regular or diabetic footwear in 9 out of 10 patients. 9 patients remain ulcer and infection free at a minimum of 7 years and maximum of 14 years follow up. Taylor Spatial Frame treatment provides an alternative to conventional surgery in high-risk complex Charcot neuroarthropathy foot and ankle deformities.

Aim and objective: The most recent wave of lower limb amputees in Gaza arises from ballistic injuries sustained during protests. This study evaluates the requirement for surgical revision of these mature stumps to allow prosthetic fit and mobility.

Materials and methods: A multidisciplinary team (MDT) comprising a prosthetist, orthopaedic and plastic surgeons and a physiotherapist screened 104 amputee stumps (103 cases). The 27 cases selected for surgical revision (stump-plasty) are the subject of this study.The MDT prescriptions of care issued at screening were compared to surgical procedures performed at stump-plasty and the findings. Compliance with the MDT prescription was recorded. Stump issues are identified to propose modifications of primary amputation technique to mitigate future revisions.Patients' healthcare status was assessed by questionnaire (EQ-5D-L5) at screening, then subsequently post-stump-plasty.

Results: More below-knee amputees (BKAs) than above-knee amputees (AKAs) required stump-plasty. Revisions varied according to the quality of tissue present at the amputation level. AKA revisions addressed bulk and contour issues whereas BKA revisions related to bone prominence, neuroma formation and lack of soft tissue cover. Despite many variations in tissue-targeted procedures being possible, the MDT prescription was followed accurately at surgery.Suggested modifications at primary amputation to decrease revisions include improved bone tip bevelling at BKA and greater soft tissue reduction at AKA. Severed nerve management needs to be rationalised to reduce primary neuroma formation and neuroma revision at stump-plasty requires consideration to attempt to reduce the recurrent risk. Removal of the fibular remnant in short BKA stumps at primary amputation could mitigate common peroneal nerve hypersensitivity later.Following stump-plasty, amputees recorded a significantly improved score in three of five dimensions of the EQ-5D-L5 questionnaire: activities, anxiety levels and pain.

Conclusion and clinical significance: Primary ballistic injury dictates the level of amputation and the resultant stump quality. Issues arising in these complex amputee stumps benefited from measured decisions and specialist care delivered by the MDT. Stump-plasty aims to improve the amputees' prosthetic fit, mobility and health.

Regeneration of the fibula following partial fibulectomy is a common and well-reported phenomenon in children. However, there is limited literature on the regeneration of fibula in skeletally mature individuals. We report a case series of regeneration of the distal fibula following partial distal fibulectomy. In both these cases, calcium sulphate (Stimulan-Biocomposites, Keele, UK) antibiotic-loaded beads were used for local delivery of a high concentration of antibiotics. However, calcium sulphate worked as an osteoconductive agent and led to regeneration of the fibula. Regeneration of the fibula has its benefits and downside. Regeneration can be beneficial in patients in whom future arthroplasty is considered as total ankle replacement would not be possible in the absence of distal fibula. On the contrary, a regenerated fibula can be a source of ankle pain related to the syndesmotic joint. There is also a report of infection recurring in the regenerated fibula. Hence, while using calcium sulphate beads either as a spacer or as a vehicle for local delivery of antibiotics, the operating surgeon needs to be aware of the risk of regeneration of the fibula if the periosteum is preserved.

Aim and objective: Genu recurvatum is a rare deformity for which minimal literature exists. Non-operative management typically gives unsatisfactory results. This study aims to evaluate the treatment of genu recurvatum with a hexapod frame.

Materials and methods: A single-center retrospective chart review of genu recurvatum cases treated with a hexapod fixator application was performed. Radiographic parameters included the following: leg length discrepancy (LLD), angle of recurvatum, angle of tilt of the tibial plateau, patellar height and anatomic proximal posterior tibial angle (aPPTA). Radiographic and functional results were evaluated.

Results: A total of five patients with six limbs corrected with a hexapod frame were found. Aetiology included post-traumatic (2), post-infectious (1) and idiopathic (3). The mean age at application was 13.36 (5.5-18.0) years. The total mean time in the fixator was 225 (160-412) days. The LLD decreased from a mean of 35.6 mm (0.7-50) preoperatively to a mean of 14.8 (1.0-39.3) postoperatively. The average patellar height remained similar 0.97 (0.69-1.2)-0.97 (0.51-1.6). The angle of the tilt of the tibial plateau improved from a preoperative mean of 66° (58.5-73.5°)-92.5° (80-98.5°). The angle of recurvatum improved from a preoperative mean of 26.4° (18.5-31°)-5.0° (0-9°). The aPTTA improved from (102-118°)-85.5° (77-96°).

Conclusion: Osteotomy distal to the tibial tuberosity and deformity correction using a hexapod frame allows for multiplanar correction. Throughout treatment, soft tissue management with physical therapy remained key to prevent knee contracture.

Clinical significance: A hexapod frame is a safe and accurate technique that allows correction of genu recurvatum along with concomitant deformities with low risk of complications.

Purpose: The purpose of this study is to evaluate the short-term results of lateral closing wedge osteotomy with medial hemiplateau elevation for the management of severe infantile Blount's disease.

Materials and methods: In this prospective study, 11 cases of severe Blount's disease (Langenskiold stages five and six) were managed in the period between January 2017 and January 2020. Double osteotomy technique was applied, namely a metaphyseal closing wedge and a medial hemiplateau elevation, through a single midline incision. Fixation was achieved by a medial anatomical locked plate. Patients were evaluated clinically according to a modified version of paediatric outcomes data collection Instrument (PODCI) and radiologically by measuring the angle between the tibial and the femoral shaft, the mechanical axis deviation (MAD) and the angle of the medial tibial plateau (MTP) depression.

Results: The average follow-up period was 2 years. Healing of the osteotomies was achieved in all cases after the index operation within an average of 3 months. Based on our modification of the PODCI score, five cases had an excellent outcome, five were good, and one case ended with a fair outcome. No major complications were encountered in this study.

Conclusion: The management of severe Blount's disease by acute correction using the aforementioned technique has been proven to achieve acceptable clinical and radiological outcomes without significant complications.

Level of evidence: Level IV case series study.
