Unlabelled: The aim of this retrospective study was to assess the relation between carpal malalignment correction and radiological union rates in surgery for scaphoid nonunions. A total of 59 scaphoid waist fracture nonunions treated with open reduction and palmar tricortical autograft were divided according to their pre- and postoperative scapholunate (SL) and radiolunate (RL) angles. We found that carpal malalignment failed to correct in 32 of 59 (54.

Trapeziometacarpal joint arthritis is a prevalent condition with a preponderance to women. Most cases are asymptomatic, but typical symptoms are pain, reduced dexterity, and functional decline. Trapeziectomy is the most common surgical treatment in the United Kingdom for patients who remain significantly symptomatic despite nonoperative measures, and this generally produces acceptable outcomes; however, a proportion of patients remain significantly symptomatic.

Aims: In the UK, fasciectomy for Dupuytren's contracture is generally performed under general or regional anaesthetic, with an arm tourniquet and in a hospital setting. We have changed our practice to use local anaesthetic with adrenaline, no arm tourniquet, and perform the surgery in a community setting. We present the outcome of a consecutive series of 30 patients.

Coronary angiography and percutaneous coronary intervention (PCI) are frequently performed procedures in the UK and the developed world, with the radial artery becoming the preferred route of access. A chronically retained macroscopic fragment of radial artery introducer sheath is a very rare complication that has not, to our knowledge, been reported. We report the case of a 62-year-old woman who underwent PCI and developed a persisting infected sinus and abscess at the cannulation site despite multiple courses of antibiotics.

Chronic exertional compartment syndrome (CECS) of the forearm may occur in sports requiring prolonged grip strength. CECS is a function of increasing pressure following muscle expansion within an inelastic tissue envelope resulting in compromise of perfusion and tissue function. Typical symptoms are pain, distal paraesthesia and loss of function.

Introduction: Acutrak 2 screws are commonly used for scaphoid fracture fixation. To our knowledge, the variation in compressive force along the screw has not been investigated before. The objectives of our study were to measure variance in compression along the length of the standard Acutrak 2 screw, to identify the region of the screw which produces the greatest compression and to discuss the clinical relevance of this to the placement of the screw for scaphoid fractures.

We report a traumatic rupture of the extensor hood of the dominant middle finger in an elite boxer. Surgical repair of the extensor hood with the metacarpophalangeal joint (MCPJ) in 90 degrees of flexion and immobilisation of the MCPJ in flexion for 4 weeks allowed successful return of function to an international level.

We discuss the appropriate assessment and treatment options available for proximal humeral fractures. Important factors to consider are the fracture pattern, the bone quality and any co-morbidities. These are common injuries and are increasing in incidence due to an ageing population.
