Brachymetatarsia is a rare deformity affecting the toes and leading to functional and psychological impact. The main aim of the study is to assess the efficacy of the surgical callus distraction technique in terms of length achievement in the paediatric group. Secondary objectives are functional improvement, reported complications and overall duration of treatment. For the series of cases involving all paediatric patients who had surgical correction at our unit from 2014 until the present, the electronic records were accessed to collect data. Pre-, peri- and post-operative assessments and investigations were used to evaluate patients' progress. The final plain films obtained were used to calculate the overall length achieved.Introduction

Aims. There is little published on the outcomes after restarting elective orthopaedic procedures following cessation of surgery due to the COVID-19 pandemic. During the pandemic, the reported perioperative mortality in patients who acquired SARS-CoV-2 infection while undergoing elective orthopaedic surgery was 18% to 20%. The aim of this study is to report the
Cam-type femoral acetabular impingement (FAI), is a common structural hip deformity and thought to be a leading cause of early hip osteoarthritis. Although patients who undergo surgical correction notice improved clinical function it is unclear what impact this has on the overall health of the cartilage. T1rho MRI cartilage mapping has been shown to be a reliable imaging technique to assess the proteoglycan (PG) content potentially serving as a biomarker. This study analyses post surgical changes in T1rho levels in hip joints treated with cam FAI. Eleven patients with a mean age of 38 (all males) underwent pre and post T1Rho Cartilage mapping of their hips at a mean time of 20 months post surgical intervention. The acetabulum was spatially divided into 4 main regions of interest (ROI), with levels of T1Rho in cartilage quantified as a whole and in each spatial segment. T1Rho signal is inversely correlated with level of PG content. All patients demonstrated loss of PG content on pre-op imaging with a T1Rho of 33.5ms+2.6ms. Preop T1rho levels were found to significantly correlated with the difference between pre-op and post-op T1rho in entire hip cartilage (R: 0.73; p=0.016). This correlation was reflected both in the anterolateral quadrant (R: 0.86; p=0.002), and in the posteriosuperior quadrant (R:0.70; p=0.035). Additionally, significant correlation was found between improvement of WOMAC pain score over time, and difference of T1rho values over time in the most lateral 3mm slice of the anterolateral quadrant (R: 0.81; p=0.045). Significant correlation was found between pre-op alpha angle at 1:30 and difference between pre-op and post-op total cartilage T1rho content (R: −065;p=0.038). T1Rho Cartilage mapping of the hip is a useful biomarker in the assessment of the surgical management of Cam type FAI. This preliminary data provides some evidence that surgical correction of the deformity can help minimise disease progression.
Several orthopaedic studies have found significant correlation between pre-operative psychological status and post-operative outcomes. The majority of research has focused on patients requiring lower limb and spine surgery. Few studies have investigated the effect of psychological status on the outcome of upper limb operations. We prospectively investigated the association between pre-operative psychological status and early postoperative shoulder pain and function in patients requiring arthroscopic subacromial decompression (ASAD) for impingement syndrome. A consecutive series of patients in 2009/10 completed questionnaires 2 weeks pre-operatively and 3 and 6 weeks post-operatively that assessed psychological state, shoulder function and pain. The hospital anxiety and depression scale, the Oxford shoulder score and a pain visual analogue scale assessed psychological status, shoulder function and shoulder pain, respectively. Data was analysed using non-parametric statistical methods.Background

Aim. In recent years, the number of victims of road traffic accidents (RTAs) and resulting surgeries have been on the rise in low income countries. Treatments are often long and costly; resources required to treat fracture related infections (FRI) continue to be a limiting factor in low income countries and standardized management protocols are lacking. This retrospective study reports our facility's experience of femoral FRI management in a low income country and evaluates the
Acromioclavicular joint injuries are one of the most common injuries in the shoulder girdle complex. Surgical management is considered based on patient profile, level of activity, pain, and classification of injury. To date, a vast array of surgical techniques have been proposed and described in the literature, a possible reason being that the optimal solution is still uncertain. The aim of this study is to determine the efficacy of an alternative surgical technique. This study is a retrospective case series of 80 patients that have been operated by a single surgeon over a period of 6 years. A novel surgical technique, the ‘BiPOD method’, was applied where a synthetic artificial ligament (LARS®) is used to reconstruct and reduce the acromioclavicular joint. The technique is done in a reproducible manner, where a single continuous artificial ligament is used to reduce and reconstruct both, the coracoclavicular and acromioclavicular ligament complexes to achieve bidirectional stability. Patients were followed-up postoperatively, either clinically where possible or telephonically. The Acromioclavicular Joint Instability Score (ACJI) and radiographic measurements were used to determine the clinical and
Augmented reality simulators offer opportunities for practice of orthopaedic procedures outside of theatre environments. We developed an augmented reality simulator that allows trainees to practice pinning of paediatric supracondylar humeral fractures (SCHF) in a radiation-free environment at no extra risk to patients. The simulator is composed of a tangible child's elbow model, and simulated fluoroscopy on a tablet device. The treatment of these fractures is likely one of the first procedures involving X-ray guided wire insertion that trainee orthopaedic surgeons will encounter. This study aims to examine the extent of improvement simulator training provides to real-world operating theatre performance. This multi-centre study will involve four cohorts of New Zealand orthopaedic trainees in their SET1 year. Trainees with no simulator exposure in 2019 - 2021 will form the comparator cohort. Trainees in 2022 will receive additional, regular simulator training as the intervention cohort. The comparator cohort's performance in paediatric SCHF surgery will be retrospectively audited using routinely collected operative outcomes and parameters over a six-month period. The performance of the intervention cohorts will be collected in the same way over a comparable period. The data collected for both groups will be used to examine whether additional training with an augmented reality simulator shows improved real-world
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
Tibiotalocalcaneal arthrodesis (TTCA) is a salvage procedure to functionally block the ankle and subtalar joints to treat severe ankle and hindfoot disease. Complication rates range between 20-40%, with below-knee amputation rate 1.5-19%. The heterogeneous patient cohort and indication(s) for surgery make post-operative outcomes difficult to predict. Consulting patients about potential pain and functional outcomes is difficult. When researching this area commonly, PROM data is used, less frequently functional objective measures like the 2-minute-walk-test (2MWT) are used. The aim was to compare the PROMs and objective outcomes between patients who underwent TTCA and BKA. Fifty-two patients underwent a TTCA using an intramedullary hindfoot nail. Indications for TTCA, post-traumatic OA, failed arthrodesis and malalignment. These patients were compared to 11 patients who underwent unilateral below knee amputation (BKA) due to trauma. Outcomes measures PROMs AOFAS ankle hindfoot scale and Shor-Form 36 (SF-36). Objective measures; 2MWT, Timed-up-and-go (TUG). Mean age TTCA 55.9, BKA 46.4. Average follow-up time 53 months. TTCA group had average 6.3 operations prior to arthrodesis (range 1-23). Of the TTCA group two ankles did not unite (7%), all complication rate 35%, 18% reported no pain. A significant negative correlation was demonstrated between the clinical outcome and the number of surgeries prior to the TTCA. TUG and 2MWT had significantly (p<0.05) better outcomes for the BKA group compared to TTCA. SF-36 BKA patients scored higher than the TTCA patients on physical functioning (p<0.01) and mental health (p<0.05) subscales as well as the mental component score (p<0.05). This study gives clinicians evidence about the natural history of hindfoot arthrodesis and functional outcomes from BKA. Hopefully this study will improve evidence to help patients and surgeons make decisions about expected
Arthroplasty procedures in low-income countries are mostly performed at tertiary centers, with waiting lists exceeding 12 to 24 months. Providing arthroplasty services at other levels of healthcare aims to offset this burden, however there is a marked paucity of literature regarding
Thoracic hyperkyphosis (TH – Cobb angle >40°) is correlated with rotator cuff arthropathy and associated with anterior tilting and protraction of scapula, impacting the glenoid orientation and the surrounding musculature. Reverse total shoulder arthroplasty (RTSA) is a reliable surgical treatment for patients with rotator cuff arthropathy and recent literature suggests that patients with TH may have comparable range of motion after RTSA. However, there exists no study reporting the possible link between patient-reported outcomes, humeral retroversion and TH after RTSA. While the risk of post-operative complications such as instability, hardware loosening, scapular notching, and prosthetic infection are low, we hypothesize that it is critical to optimize the biomechanical parameters through proper implant positioning and understanding patient-specific scapular and thoracic anatomy to improve
Introduction. Snapping hip syndrome is a common condition affecting 10% of the population. It is due to the advance of the iliotibial band (ITB) over the greater trochanter during lower limb movements and often associated with hip overuse, such as in athletic activities. Management is commonly conservative with physiotherapy or can be surgical to release the ITB. Here we carry out a systematic review into published surgical management and present a case report on an overlooked cause of paediatric snapping hip syndrome. Materials & Methods. A systematic review looking at published surgical management of snapping hip was performed according to PRISMA guidelines. PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Library databases were searched for “((Snapping hip OR Iliotibial band syndrome OR ITB syndrome) AND (Management OR treatment))”. Adult and paediatric published studies were included as few results were found on paediatric snapping hip alone. Results. 1548 studies were screened by 2 independent reviewers. 8 studies were included with a total of 134 cases, with an age range of 14–71 years. Surgical management ranged from arthroscopic, open or ultrasound guided release of the ITB, as well as gluteal muscle releases. Common outcome measures showed statistically significant improvement pre- and post-operatively in visual analogue pain score (VAPS) and the Harris Hip Score (HHS). VAPS improved from an average of 6.77 to 0.3 (t-test p value <0.0001) and the HHS improved from an average of 62.6 to 89.4 (t-test p value <0.0001). Conclusions. Although good
Knowledge of the premorbid glenoid shape and the morphological changes the bone undergoes in patients with glenohumeral arthritis can improve
Resection of the proximal femur raises several challenges to the orthopedic oncology surgeon. Among these is the re-establishment of the abductor mechanism that might impacts on hip function. Extent of tumor resection and surgeons’ preferences dictate the reconstruction method of the abductors. While some surgeons advocate the necessity of greater trochanter (GT) preservation whenever possible, others attempt direct soft tissues reattachment to the prosthesis. Sparse data in the literature evaluated the outcomes of greater trochanter fixation to the proximal femur megaprosthesis. This is a retrospective monocentric study. All patients who received a proximal femoral replacement after tumor resection between 2005 and 2021 with a minimum follow-up of three months were included. Patients were divided into two groups: (1) those with preserved GT reattached to the megaprosthesis and (2) those with direct or indirect (tenodesis to fascia lata) abductor muscles reattachment. Both groups were compared for
Introduction. W. ide . A. wake . L. ocal . A. naesthetic . N. o . T. ourniquet (WALANT) is a well- established day case procedure for carpal tunnel release with several advantages and enhanced post-operative recovery. Use of Local anaesthesia with Adrenaline using a 27G needle allows a bloodless field and distraction techniques achieve patient comfort during the procedure. Objectives. This retrospective, observational cohort study assesses patient satisfaction and undertakes functional evaluation using the validated Boston Carpal Tunnel Questionnaire (BCTQ) following WALANT technique for carpal tunnel release (CTR). The BCTQ has a symptom severity scale based on 11 items and a functional status scale of 8 elements. Further we compare
Paediatric bone sarcomas around the knee are often amenable to either endoprosthetic reconstruction or rotationplasty. Cosmesis and durability dramatically distinguish these two options, although patient-reported functional satisfaction has been similar among survivors. However, the impact on oncological and
Aim. Fungal orthopaedic infections most commonly affect people with complex surgical histories and existing comorbidities. Recurrence and re-infection rates are high, even with optimal surgical and systemic antifungal treatment. AmBisome liposomal amphotericin B has been suggested for local antifungal therapy, as an adjunctive treatment for fungal osteoarticular infections. Few case series have examined its clinical use when combined with polymethylmethacrylate cement PMMA), or with absorbable local antibiotic carriers. We aimed to evaluate the clinical use of local antifungal therapy with AmBisome liposomal amphotericin B (ABlaB), including tolerated doses, serious adverse events, and treatment outcomes. Method. A retrospective cohort of all patients treated with local antifungal therapy with ABlaB between January 2016 and January 2021 in a specialist orthopaedic hospital was identified using pharmacy records. Renal function, serious adverse events during treatment,
Introduction. We aimed to determine whether there are differences in patient-reported quality of life (QoL) outcome between local flap versus free flap. Materials and Methods. All patients admitted with lower limb open fractures were retrospectively reviewed. Patient notes were assessed for demographics, time to fracture union, wound healing and patient-reported QoL with EQ-5D-5L, alongside a novel flap assessment tool. Results. A total of 40 patients had flap reconstruction of their lower limb injury; 23 local flap (Group I) and 17 free flaps (Group II). The average length of follow-up was 33.8 months. Group I - 10 revisions of flaps (43.5%) and 14 surgical complications (60.9%). Fracture union was 171 days and wound healing 130 days. EQ-5D index and EQVAS scores were 0.709 and 79.3, respectively. Group II – 8 revision of flaps (47.1%) and 12 surgical complications (70.6%). Fracture union was 273 days and wound healing 213 days. EQ-5D index and EQ-VAS scores were 0.525 and 57.2, respectively. Aesthetic appeal - 48% Group I vs. 66% Group II. Significant differences were found between the two flap groups with higher scores for daily living in Group I (p–0.007) compared to higher overall flap ratings in Group II (p–0.049). Both groups were comparable in terms of complications, while flap congestion and dehiscence were more common with free flaps. statistical interrogation did not elicit significance (p > 0.05). Conclusions. Local flap and free flap techniques offer distinct advantages. Local flaps have a better
Background. Total hip arthroplasty (THA) has been and continues to be the gold standard for treatment of end-stage osteoarthritis. With each year, implant characteristics are evolving to increase patient-reported outcomes and decrease complications. Purpose: to report minimum 2-year outcomes and complications in patients who underwent robotic-arm assisted THA using Corin versus Stryker-type implants. Methods. Data were prospectively collected on patients who underwent THA with Corin-type implants (both cup and stem) and THA using Stryker implants between June 2011 and July 2016. A 1:1 propensity match was performed using the following 5 covariates: age, body mass index, gender, Charlson score and smoking status.
The vast majority of total hip replacements (THR) implanted today enable modularity by means of a tapered junction; based on the Morse taper design introduced for cutting tools in the 19. th. Century . 1. Morse-type tapers at the head-stem junction provide many benefits, key for a successful
