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.

There are no detailed reports of the incidence of venous thromboembolism (VTE) in pelvic and acetabular fractures in the Asian population. The purpose of this study was to investigate the incidence of VTE in pelvic and acetabular fractures in the Japanese population. ⋯ We should be vigilant for the high incidence of VTE, especially PTE, in patients with pelvic and acetabular fractures in the Japanese population.

The aim of this study was to investigate the pain patterns in patients with end-stage hip disease and to assess the response after total hip arthroplasty (THA). ⋯ The distribution of pain from end-stage hip diseases is versatile, and presence of pain in areas other than around the hip is not uncommon. LBP was more common in patients with longer duration of symptoms. THA satisfactorily resolves the pain in all areas soon after surgery.
