The Carpal Tunnel Syndrome Instrument (CTSI) is a disease-specific, self-administered questionnaire that consists of a symptom severity scale (SS) and a functional status scale (FS). The CTSI was cross-culturally adapted and developed by the Impairment Evaluation Committee, Japanese Society for Surgery of the Hand (JSSH). The purpose of this study was to test the reliability, validity, and responsiveness of the Japanese version of the CTSI (CTSI-JSSH). ⋯ The CTSI-JSSH has sufficient reliability, validity, and responsiveness to assess the health status in carpal tunnel syndrome.

An ideal dural substitute that enables watertight closure, has sufficient strength, and can be absorbed without remnant materials that induce inflammation, adhesion, and infection is not available. The purpose of this study was to evaluate the efficacy of a bioabsorbable polyglycolic acid (PGA) mesh and fibrin glue as a substitute for dural repair. ⋯ The use of PGA mesh and fibrin glue for the repair of dura mater is a useful method of preventing CSF leakage in spinal surgery.

Osteotomy as a treatment for bilateral osteoarthritis of the hip is controversial because of deterioration of the contralateral side. We tried to not cause the contralateral hip to deteriorate even more while curing osteoarthritis by simple methods (release of iliopsoas and adductor longus muscle tendons and lateral transfer of the greater trochanter; Maquet's operation) during the rehabilitation period of Pauwels' valgus osteotomy. ⋯ Bilateral simultaneous femoral osteotomies for the late stages of osteoarthritis could be an alternative to bilateral total hip arthroplasties.

The thrust plate prosthesis is an implant with a metaphyseal fixation at the proximal femur that transmits the load forces of the hip onto the femoral neck. ⋯ The thrust plate prosthesis shows midterm results comparable to those of the cementless stemmed prosthesis and supplies advantages, especially for younger patients with femoral head necrosis, because of its metaphyseal bone-preserving fixation.
