Ankle fractures are extremely common but unfortunately, over 20% fail to obtain good to excellent recovery. For those requiring surgical fixation, usual-care post-surgery has included six-weeks cast immobilisation and non-weightbearing. Disuse atrophy and joint stiffness are detrimental sequelae of this management. While rehabilitation, starting at two-weeks post-surgery is viewed as safe, the literature contains methodological flaws and a lack of focus on early exercise, perpetuating the controversy over the effectiveness of early exercise interventions. Our objectives were to determine if following operative fixation for Weber B fracture, the physiotherapy intervention, early motion and directed exercise (EMADE), applied in the clinical setting, were superior to Usual-care at 12-weeks (primary outcome) and 24-weeks.Background
Objectives
Leg length discrepancy (LLD) in patients with unilateral developmental dysplasia of the hip (DDH) can be problematic for both patients and surgeons. Patients can acquire gait asymmetry, back pain, and arthritis. Surgical considerations include timing of correction and arthroplasty planning. This study audits standing long leg films performed at skeletal maturity in our patients. The aim of this study is to identify if surgical procedure or AVN type could predict the odds of needing an LLD Intervention (LLDI) and influence our surveillance. Hospital database was searched for all patients diagnosed with DDH. Inclusion criteria were patients with appropriately performed long leg films at skeletal maturity. Exclusion criteria were patients with non DDH pathology, skeletally immature and inadequate radiographs. All data was tabulated in excel and SPSS was used for analysis. Traumacad was used for measurements and AVN and radiologic outcome grades were independently classified in duplicate.Introduction
Materials and Methods
To determine mortality risk after first revision total hip arthroplasty (THA) for periprosthetic femoral fracture (PFF), and to compare this to mortality risk after primary and first revision THA for other common indications. The study cohort consisted of THAs recorded in the National Joint Registry between 2003 and 2015, linked to national mortality data. First revision THAs for PFF, infection, dislocation, and aseptic loosening were identified. We used a flexible parametric model to estimate the cumulative incidence function of death at 90 days, one year, and five years following first revision THA and primary THA, in the presence of further revision as a competing risk. Analysis covariates were age, sex, and American Society of Anesthesiologists (ASA) grade.Aims
Methods
Despite advances in the treatment of paediatric hip disease, adolescent and young adult patients can develop early onset end-stage osteoarthritis. The aims of this study were to address the indications and medium-term outcomes for total hip arthroplasty (THA) with ceramic bearings for teenage patients. Surgery was performed by a single surgeon working in the paediatric orthopaedic unit of a tertiary referral hospital. Databases were interrogated from 2003 to 2017 for all teenage patients undergoing THA with a minimum 2.3 year follow-up. Data capture included patient demographics, the underlying hip pathology, number of previous surgeries, and THA prostheses used. Institutional ethical approval was granted to contact patients for prospective clinical outcomes and obtain up-to-date radiographs. In total, 60 primary hips were implanted in 51 patients (35 female, 16 male) with nine bilateral cases. The mean age was 16.7 years (12 to 19) and mean follow-up was 9.3 years (2.3 to 16.8).Aims
Methods
The aim of this study was to investigate the outcomes of Vancouver
type B2 and B3 fractures by performing a systematic review of the
methods of surgical treatment which have been reported. A systematic search was performed in Ovid MEDLINE, Embase and
the Cochrane Central Register of Controlled Trials. For inclusion,
studies required a minimum of ten patients with a Vancouver type
B2 and/or ten patients with a Vancouver type B3 fracture, a minimum
mean follow-up of two years and outcomes which were matched to the type
of fracture. Studies were also required to report the rate of re-operation
as an outcome measure. The protocol was registered in the PROSPERO
database. Aims
Materials and Methods
Purpose of the study is to investigate the outcome of the patients with Perthes disease who have had a surgical dislocation of their hip for the treatment of resultant symptoms from the disease process. Retrospective review of consecutive patients treated with surgical dislocation of the hip for Perthes disease. Review of clinical case notes and radiological imaging. Patient outcome was assessed at follow-up. Between 2010 and 2015, 31 cases of surgical hip dislocation were performed for Perthes disease at our institution by 2 senior surgeons. Age range at time of surgery was 12–33. Male:female ratio was 13:18; right:left ratio was 15:17. Age at the time of Perthes diagnosis was between 3 and 13 years, with 3 diagnosed retrospectively. Mean follow-up was 18months. All patients had an EUA and arthrogram while 61.3%(19/31) had previous surgery for Perthes. 71%(22/31) required a labral repair, 6.5%(2/31) had a peri-acetabular osteotomy at the time of surgery and 3.2%(1/31) required a proximal femoral valgus osteotomy. 22.5%(7/31) required microfracture (femoral head or acetabulum): all of whom had evidence of contained area of degenerative changes on preoperative MRI. 64.5%(20/31) had the trochanteric screws removed. Complications included 1 greater trochanter non-union, 1 pain secondary to suture anchor impinging on psoas tendon, 1 AVN leading to early THR 12 months post-op. Another 2 had further deterioration of degenerative changes and pain leading to THR 18 and 24 months post-op. All 3(9.7%) had microfracture at the time of the dislocation for established degenerative change and also required custom made prostheses. Surgical hip dislocation is an option in treating Perthes patient with resultant symptoms such as impingement. Improved outcome is seen in patients who are younger with a congruent hip joint in contrast to those with established degenerative change evident on MRI / intraoperatively and have an arrow shaped femoral head.
Congenital pseudarthrosis of the tibia (CPT)
is a rare but well recognised condition. Obtaining union of the pseudarthrosis
in these children is often difficult and may require several surgical
procedures. The treatment has changed significantly since the review
by Hardinge in 1972, but controversies continue as to the best form
of surgical treatment. This paper reviews these controversies. Cite this article:
Through the paediatric LCP Hip plating system, the highly successful technique of the locking compression plate used in adult surgery, has been incorporated in a system dedicated to paediatrics. The purpose of this study was to review the outcome of the paediatric LCP Hip plate use in children, both with and without neuromuscular disease, for fixation of proximal femoral osteotomy for a variety of indications. We retrospectively reviewed the notes and radiographs of all those children who have had Paediatric LCP Hip Plate for the fixation of proximal femoral osteotomy and proximal femur fractures in our institution, between October 2007 and July 2010, for their clinical progress, mobilization status, radiological healing and any complications.Introduction
Materials and methods
Restrictions placed on the working hours of doctors have led to increasing time-pressures on surgical training. Consequently, there has been growing interest in developing new techniques to teach and assess technical skills. The primary aim of this study was to determine whether a novel set of visual parameters assessing visuospatial ability, fine motor dexterity and gaze control could objectively distinguish between varying levels of arthroscopic experience. The secondary aim was to evaluate the correlations between these new parameters and previously established technical skill assessment methods. 27 subjects were divided into a “novice” group (n=7), “trainee” group (n=15) and expert group (n=5) based on previous arthroscopic experience. All subjects performed a diagnostic knee arthroscopy task on a simulator. Their performance was assessed using new simple visual parameters that included “prevalence of instrument loss,” “triangulation time” and “prevalence of look downs”. In addition, performance was also evaluated using previously validated technical skill assessment methods (a global rating scale and motion analysis).Introduction
Methods
Motion analysis is a validated method of assessing technical dexterity within surgical skills centers. A more accessible and cost-effective method of skills assessment is to use a global rating scale (GRS). We aimed to perform a validation experiment to compare an arthroscopic GRS against motion analysis for monitoring orthopaedic trainees learning simulated arthroscopic meniscal repairs. An arthroscopic meniscal repair task on a knee simulator was set up in a bioskills laboratory. Nineteen orthopaedic trainees with no experience of meniscal repair were recruited and their performance assessed whilst undertaking a standardized meniscal repair on 12 occasions. An arthroscopic GRS, assessing parameters such as “depth perception,” “bimanual dexterity,” “instrument handling,” and “final product analysis” was used to evaluate technical skill. Performance was assessed blindly by watching video recordings of the arthroscopic tasks. Dexterity analysis was performed using a motion analysis tracking system which measured “time taken,” “total path length of the subject's hands,” and “number of hand movements”.Introduction
Methods
Despite interest, the current rate of day-case anterior cruciate ligament reconstruction (ACLR) in the UK remains low. Although specialised care pathways with standard operating procedures (SOPs) have been effective in reducing length of stay following some surgical procedures, this has not been previously reported for ACLR. We evaluate the effectiveness of SOPs for establishing day-case ACLR in a specialist unit. Fifty patients undergoing ACLR between May and September 2010 were studied prospectively (“study group”). SOPs were designed for pre-operative assessment, anaesthesia, surgical procedure, mobilisation and discharge. We evaluated length of stay, readmission rates, patient satisfaction and compliance to SOPs. A retrospective analysis of 50 patients who underwent ACLR prior to implementation of the day-case pathway was performed (“standard practice group”).Background

Through the paediatric LCP Hip plating system (Synthes GmBH Eimattstrasse 3 CH- 4436 Oberdorff), the highly successful technique of the locking compression plate used in adult surgery, has been incorporated in a system dedicated to pediatrics. We are presenting the outcome of the paediatric LCP hip plating system used for a variety of indications in our institution. We retrospectively reviewed the notes and radiographs of all those children who have had Paediatric LCP Plate for the fixation of proximal femoral osteotomy and proximal femur fractures in our institution, between October 2007 and July 2010, for their clinical progress, mobilization status, radiological healing and any complications. Forty-three Paediatric LCP hip plates were used in forty patients (24 males and 13 females) for the fixation of proximal femoral osteotomies (n=40) and proximal femur fractures (n=3). The osteotomies were performed for a variety of indications including Perthes disease, developmental dysplasia of hip, Cerebral Palsy, Down's syndrome, coxa vara, Leg length discrepancy and previous failed treatment of Slipped Upper Femoral Epiphysis. Twenty-five children were allowed touch to full weight bearing post operatively. Two were kept non-weight bearing for 6 weeks. The remaining 13 children were treated in hip spica due to simultaneous pelvic osteotomy or multilevel surgery for cerebral palsy. All osteotomies and fractures radiologically healed within 6 months (majority [n=40] within 3 months). There was no statistically significant difference (p= 0.45) in the neck shaft angle between the immediately postoperative and final x-rays after completion of bone healing. Among the children treated without hip spica, 1 child suffered a periprosthetic fracture. Of the children treated in hip spica, 2 had pressure sores, 3 had osteoporotic distal femur fractures and 2 had posterior subluxations requiring further intervention. There were no implant related complications. The Paediatric LCP Hip Plate provides a stable and reliable fixation of the proximal femoral osteotomy performed for a variety of paediatric orthopaedic conditions.
The purpose was to determine if the use of cold irrigation fluid in routine knee arthroscopy leads to a reduction in post operative pain. Some surgeons use cooled irrigation fluid in knee arthroscopy in the hope that it may lead to a reduction in post operative pain and swelling. There is currently no evidence for this, although there is some evidence to support the use of cold therapy post operatively in knee surgery.Purpose
Background
A feasibility study of the use of an MRI based patient specific knee arthroplasty system within the NHS. Introducing new technologies within a public funded health system can be challenging. We assess the use and potential benefit of customised jigs for knee arthroplasty. Outcomes assessed were safety and accuracy of implantation. Eight knee replacements using custom jigs were compared to 11 conventionally instrumented replacements matched to surgeon and operative day. Parameters measured include tourniquet time; drain output; hospital stay; adjusted change in haemoglobin; complications; and component position on post-operative long-leg alignment films None of the parameters observed demonstrated a statistically significant difference from the conventional arthroplasty group. No complications were seen in either group. No significant differences were seen in alignment. Our early experiences show that this technology appears safe and allows accurate implantation of the prosthesis. There was a trend for decreased stay and blood loss. The health economic benefits of navigational arthroplasty have been demonstrated in other studies and come from the lack of instrumentation of the intramedullary canal. MRI based patient specific instrumentation is considered technically easier and more convenient than intra-operative navigation. A larger study is planned to assess the health economic implications of adopting this new technology.
The aim of this study was to investigate the
effect of training on the arthroscopic performance of a group of
medical students and to determine whether all students could be
trained to competence. Thirty-three medical students with no previous
experience of arthroscopy were randomised to a ‘Trained’ or an ‘Untrained’
cohort. They were required to carry out 30 episodes of two simulated
arthroscopic tasks (one shoulder and one knee). The primary outcome variable
was task success at each episode. Individuals achieved competence
when their learning curve stabilised. The secondary outcome was
technical dexterity, assessed objectively using a validated motion
analysis system. Six subjects in the ‘Untrained’ cohort failed to
achieve competence in the shoulder task, compared with one in the ‘Trained’
cohort. During the knee task, two subjects in each cohort failed
to achieve competence. Based on the objective motion analysis parameters,
the ‘Trained’ cohort performed better on the shoulder task (p <
0.05) but there was no significant difference for the knee task
(p >
0.05). Although
The position of the gastrocnemius tendon relative to the calcaneus and fibular head distance may be different in children with cerebral palsy (CP) when compared to normal children. However, no such data is available. Usually, palpation of the muscle bellies or previous experience of the operating surgeon is employed to place the surgical incision. Inaccurate localisation may cause incorrect incision and a risk of iatrogenic damage to the vital structures (i.e. sural nerve). The aim of our study is to compare gastrocnemius muscle length in-vivo between paretic and unaffected children and suggest a formula to localise muscle-tendon junction. Ten children with di/hemiplegia (seven females and three males; mean age 8y 7mo, range 2–14y) were recruited. None of them had received any conventional medical treatment. An equal number of age/sex matched, typically developing children (mean age 9y 1mo, range 4–14y) were recruited. Participants lay prone on an examination plinth with their feet hanging from its edge. Sagittal-plane ultrasound scanning of the gastrocnemius muscle at rest was performed to measure the length of gastrocnemius bellies. We also measured the heights, lower leg lengths, thigh lengths and leg lengths. At similar age, the lower leg lengths in CP patients were shorter than normal children. Similarly, gastrocnemius medial (GM) muscles were shorter in CP children when compared to similar aged normal children. In CP children, the GM muscle and lower leg ratio ranges between 35 to 50% with an average ratio of 45%. When compared to leg length, the ratio is 22%. Using these figures we created a formula that may be used clinically to identify the tendon for open or endoscopic lengthening and also to make simple and accurate localisation of GM-tendon junction for surgical access. This minimizes the risk of iatrogenic neurovascular injuries and decreases the length of the surgical incision.
