Multicenter Study Clinical TrialGlenoid morphology affects the incidence of radiolucent lines around cemented pegged polyethylene glenoid components.
Radiolucent lines (RLL) are frequent findings around cemented all-polyethylene glenoid implants. The present study evaluates the frequency, extend and the clinical impact of RLL around a cemented two-pegged glenoid implant with special focus on the influence of preoperative glenoid morphology. Our hypothesis was that glenoid morphology does not affect clinical outcome and RLL in the investigated setting. ⋯ Level IV case series study.

ReviewThe assessment of neutrophil CD64 count as an early warning marker of joint replacement infection.
120,000 hip and knee replacements are performed each year in the UK and more than 1 % of these require revision surgery due to infection. Current diagnostic tests used to diagnose infection of joint replacements, including the current gold standard C-reactive protein, which offers poor specificity when diagnosing infection in the post-operative period. In the post-operative period these tests are unable to differentiate between physiological inflammation and infection of the replacement. ⋯ Data from several studies utilising a flow cytometer support the view that CD64 is firstly, a good marker of systemic infection and secondly, when studied in conjunction with musculoskeletal infections alone, is a sensitive and specific marker of this type of infection. However, meta-analysis of studies in this field concludes that more highly powered studies are needed before definite conclusions can be drawn. Despite this, the studies do portray a strong case for CD64 being the future of diagnosis of post-operative infection.

Comparative StudyOperative treatment for volar plate avulsion fractures of the fingers.
We present our experience with 14 volar plate avulsion fractures of the fingers that were treated by excision or internal fixation and discuss the factors affecting the operative techniques and results. Fourteen cases were divided into two groups: the volar plate avulsions with excision (eight cases) and the volar plate avulsions with fixation (six). We compared clinical factors between fracture groups and between fixation methods. ⋯ All fixated fractures healed and the time to union did not differ based on fixation method. The true size of the fracture fragment was larger than expected based on the X-ray and the fragments were usually rotated by pull of the volar plate or ligament. The size and shape of the avulsed fragment might be important factors to determine the treatment method, but the results after operation were not significantly different whether the fragment was excised or fixed.

Case ReportsSevere posttraumatic radiocarpal cartilage damage: first report of autologous chondrocyte implantation.
Case report. ⋯ The case presented here demonstrates the first use of autologous chondrocyte implantation for cartilage reconstruction using an in situ polymerizable albumin-hyaluronic acid gel after traumatic cartilage lesion with 4° cartilage damage of the wrist in a 22-year-old non-smoking, active and healthy man. Initial results are promising in terms of mobility, pain and patient outcome. However, further clinical studies have to be performed with larger number of cases.

Clinical TrialInfluence of arthroscopic lateral release on functional recovery in adolescents with recurrent patellar dislocation.
The aim of this study is to prove the influence of the arthroscopic lateral release on functional recovery in adolescents with recurrent lateral dislocation of patella. ⋯ Arthroscopic lateral release successfully treats recurrent patellar dislocations in adolescents, influences functional recovery and improves knee function.
