Retrospective case series. ⋯ Neuropathic pain after surgical resection reduces the QOL of patients with IMSCTs, and pain severity varies with the tumor's location and histological features, the severity of paralysis, and the location of pain relative to the tumor.

A persistent articular gap and a step-off of ≥1 mm after a distal radial fracture (DRF) may lead to post-traumatic arthritis of the radiocarpal joint. This study aims to arthroscopically assess the reduction in the articular surface in patients requiring volar locked-plate fixation for DRF via fluoroscopy-guided open reduction and internal fixation (ORIF). ⋯ Since the cutoff value of 7.85 mm derived from total predisplacement is a good indicator of post-ORIF residual total incongruity of ≥1 mm, it is also a good indicator of the need for arthroscopic reduction.

The Oxford hip score (OHS) is one of the most widely used scoring systems to assess clinical outcome for patients with total hip arthroplasty (THA). Few studies have evaluated the OHS in non-Western patients with other cultural backgrounds, particularly Asians. Translation and transcultural adaptation of the OHS into the Korean was performed in accordance with international recommendations and the psychometric properties were tested. ⋯ This study shows that the OHS developed in the West, with transcultural adaptation, is relevant for the patients undergoing THA in Korea.

Our objective was to evaluate the effectiveness of arthroscopic distal clavicle resection in cases presenting with pain and subtle instability after neglected grade II acromioclavicular (AC) joint dislocation. ⋯ Arthroscopic distal clavicle resection statistically improved the pain score, Constant score and strength for grade II AC injury with subtle distal clavicle instability. However, six patients (33.5 %) were not satisfied subjectively. This procedure seemed to be a reasonable initial treatment option with lower morbidity.

Intramedullary reaming and nailing of long bones impairs the endosteal circulation, often causing necrosis of the inner region of the bone cortex. We hypothesized that compensatory hypertrophy of the periosteal microcirculation may develop in response to mechanical destruction of the endosteum, and that this may affect bone survival in these circumstances. In these studies, nailing was performed with materials that affect regeneration of the endosteum differently, and the effects on the tibial periosteal microvasculatory organization were examined. ⋯ Destruction of the endosteal microcirculation per se brings about an increase in periosteal vascular density, which is further augmented if implantation is performed with a material which delays regeneration of the endosteal circulation.
