Multiple devices can stabilise the MTP joint for arthrodesis. The ideal implant should be easy to use, provide reproducible and high quality results, and ideally enable early rehabilitation to enable faster return to function, whilst lessening soft tissue irritation. We prospectively evaluated the combination of the IO-Fix (Extremity Medical, NJ, USA) device which consists of an intra-osseous post and lag screw that offers these features with full bearing of weight after surgery. 67 feet in 65 patients were treated over 31 months. After excluding patients lost to follow-up, undergoing revision arthrodesis, or concomitant first ray procedures, there were 54 feet in 52 patients available with a minimum 12 month follow-up with clinical and radiographic outcomes. All patients were treated using a similar operative technique with immediate bearing of weight in a rigid soled shoe.Abstract

Acute Achilles tendon (AT) rupture management remains debatable but non-operative functional regimes are beginning to dominate current treatment algorithms. The aim of this study was to identify predictors of functional outcome in patients with AT ruptures treated non-operatively with an immediate weight bearing functional regime in an orthosis. Analysis of prospectively gathered data from a local database of all patients treated non-operativelyat our institution with anAT rupture was performed. Inclusion criteria required a completed Achilles Tendon Rupture Score (ATRS) at a minimum of 8 months post rupture. The ATRS score was correlated against age, gender, time following rupture, duration of treatment in a functional orthoses (8- and 11-week regimes) and complications. 236 patients of average age 49.5 years were included. The mean ATRS on completion of rehabilitation was 74 points. The mean ATRS was significantly lower in the 37 females as compared to the 199 males, 65.8 vs 75.6 (p = 0.013). Age inversely affected ATRS with a Pearsons correlation of −0.2. There was no significant difference in the ATRS score when comparing the two different treatment regime durations. There were 12 episodes of VTE and 4 episodes of re-rupture. The ATRS does not change significantly after 8 months of rupture. Patients with AT ruptures treated non-operatively with a functional rehabilitation regime demonstrate good function with low re-rupture rates. Increasing age and female gender demonstrate inferior functional outcomes.
In Total Hip Arthroplasty (THA), polyethylene wear reduction is key to implant longevity. Oxidized Zirconium (OxZi) unites properties of a ceramic bearing surface and metal head, producing less wear in comparison to standard Cobalt-Chromium (CoCr) when articulating with Cross-linked polyethylene (XLPE) in vitro. This study investigates in vivo polyethylene (PE) wear, outcomes and complications for these two bearing couples in patients at 5 year follow-up 400 patients undergoing THA across four institutions were prospectively randomised into three groups. Group I received a cobalt-chrome (CoCr) femoral head/ cross-linked polyethylene (XLPE) liner; Group II received an OxZi femoral head/ ultrahigh molecular weight polyethylene (UHMWPE) liner; Group III received an OxZi femoral head/XLPE liner. All bearing heads were 32 mm. Linear wear rate was calculated with Martell computer software. Functional outcome and complications were recorded.Introduction
Methods
Patellar instability is a complex, multi-factorial disorder. Radiological assessment is regarded as an important part of the management of this population. The purpose of this study was to determine the intra- and inter-rater reliability of common radiological measurements used to evaluate patellar instability. One hundred and fifty x-rays from 51 individuals were reviewed by five reviewers: two orthopaedic trainees, a radiological trainee, a consultant radiologist and an orthopaedic physiotherapist. Radiological measurements assessed included patellar shape, sulcus angle, congruence angle, lateral patellofemoral angle (LPA), lateral patellar displacement (LPD), lateral displacement measurement (LDM), boss height, and patellar height ratios (Caton-Deschamps, Blackburne-Peel, Insall-Salvati). All assessors were provided with a summary document outlining the method of assessing each measurement. Bland-Altman analyses were adopted to assess intra- and inter-rater reliability.Background
Methods
To evaluate the results and complications of bone transport in the treatment of massive tibial bone defects, using the Ilizarov method. 15 patients underwent bone transport using the Ilizarov technique to treat massive tibial bone defects. The average age of the patients was 8.7 years (3–24 years) and the mean bone defect was 10.8 cms. Following a latent period of 1 week, distraction of the transport doughnut was commenced at 1mm/24 hours in 4 quarterly turns. A docking procedure was performed in 7 cases which involved freshening of the bone ends and autogenous bone grafting from the iliac crest. Following docking the fixator was removed once the regenerate had consolidated.Aim
