Hip and groin injuries are common in athletes participating in high level sports. Adductor muscle tendon injuries represent a small but important number of these injuries. Avulsion injuries involving tendons attaching to the symphysis pubis have previously been described and can be managed both operatively and non-operatively. The aim is to describe a rare variant of this injury; complete avulsion of the adductor sleeve complex including adductor longus, pectineus and rectus abdominus. A surgical technique is then outlined which promotes a full return to pre-injury level of sporting activity. Fifteen high level athletes with an MRI confirmed acute adductor complex avulsion injury (6–34 days) were identified from the institution's sports injury database over a 10 year period. All underwent surgical repair. The operative procedure comprised anatomical attachment of the avulsed tissues in all cases (plus mesh reinforcement of the inguinal wall in 7 patients). All underwent a standard format of rehabilitation which was then individualised to be sport specific.Introduction
Patients/Materials & Methods
To assess the clinical and radiologic outcome of MM patients with thoracic spine involvement and concomitant pathologic sternal fractures with a resultant severe sagittal plane deformity. A prospective cohort study (n=391) was performed over a 7-year period at a national tertiary referral centre for the management of multiple myeloma with spinal involvement. Clinical, serological and pathologic variables, radiologic findings, treatment strategies and outcome measures were prospectively collected. Pre-treatment and post-treatment clinical outcome measures utilised included EQ-5D, VAS, ODI and RMD scoring systems. 13 MM patients presented with a severe symptomatic progressive sagittal plane deformity with a history of pathologic thoracic compression fractures and concomitant pathologic sternal fracture. All patients with concomitant sternal fractures displayed the radiographic features and spinopelvic parameters of positive sagittal malalignment and attempted clinical compensation. All patients had poor health related quality of life measures when assessed. Pathologic sternal fracture in a MM patient with thoracic compression fractures is a risk factor for the development of a severe thoracic kyphotic deformity and sagittal malalignment. This has been demonstrated to be associated with a very poor health related quality of life.
Technology in Orthopaedic surgery has become more widespread in the past 20 years, with emerging evidence of its benefits in arthroplasty. Although patients are aware of benefits of conventional joint replacement, little is known on patients' knowledge of the prevalence, benefits or drawbacks of surgery involving navigation or robotic systems. In an outpatient arthroplasty clinic, 100 consecutive patients were approached and given questionnaires to assess their knowledge of Navigation and Robotics in Orthopaedic surgery. Participation in the survey was voluntary.Introduction
Materials & Methods
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

Materials and methods
Adductor muscle and tendon injuries are commonly seen in sport. Complete adductor avulsions have been described and can be managed non-operatively or operatively. A rare variant of this injury is the complete avulsion of the adductor complex with the pectineus and rectus abdominus amounting to a complete sleeve avulsion from the pubis. This is a severe injury that is increasingly recognised due to improved imaging and lower diagnostic threshold. We describe the surgical management of twelve athletes with this severe injury.Background
Purpose
A new conservative hip stem has been designed to address the complex problem of total hip arthroplasty in the younger population. To assess the stability and strain distribution of a new conservative hip stem.Introduction
