BACKGROUND: Intraoperative pathological diagnosis has a major influence on the intra- and postoperative management of spinal cord tumors. Thus, the aim of this study was to assess the reliability of intraoperative pathological diagnosis for spinal cord lesions by comparing it with the final pathological diagnosis and to determine its usefulness and limitations. METHOD: Three-hundred and three consecutive patients (mean age, 53.9 years) with neoplastic spinal cord lesions who underwent initial surgery between 2000 and 2021 were included...

BACKGROUND: Postoperative infection is a devastating complication in limb salvage surgery for malignant soft tissue tumors. The low absolute case numbers of these rare cancers represent a bottleneck for data collection and analysis. The administration of nationwide registry data is a practical option for the accumulation of cases. METHODS: Data on malignant soft tissue tumor resection were extracted from the Bone and Soft Tissue Tumor Registry in Japan. The incidence of postoperative infection and its risk factors were analyzed...

BACKGROUND: Limb immobilization is considered to contribute to limb pain including hyperalgesia. Approximately 50% of patients with such chronic limb pain complain that their abnormal pain worsens after exposure to cold. However, there have been few studies on the relationship between limb immobilization and cold hypersensitivity. The aim of this study was to examine whether limb immobilization induces cold hypersensitivity, and whether physical exercise such as ankle stretching prevents its induction in model mice...

BACKGROUND: Intraoperative stem anteversion, which is the angle between the lower leg axis and the trial-stem axis with hip flexion and adduction, is generally evaluated by the surgeon's visual estimation during total hip arthroplasty (THA). However, the conventional approach can be influenced by knee osteoarthritis or uncertain surgeon's observation point. Therefore, we developed a new method for measuring the stem anteversion angle in the neutral hip position using an original rod attached to the trial-stem perpendicular to the long axis and parallel to the stem neck...

BACKGROUND: One of most severe clinical problems related to Apert foot anomalies is medial angulation deformities of the great toe as the foot grows. CASE PRESENTATION: The patient was a 22-month-old Japanese child with Apert syndrome, who had broad bilateral great toe showing medially angulated deformity. We performed two-stage surgical treatment including distraction of the remarkable narrowing the first inter-metatarsal space using an external distractor device, and the corrective wedge-osteotomy of the first metatarsal with a graft of wedged bone in the reverse direction and inter-positioning of the resected local bone between the first and second metatarsal to preserve the space...

Calcium pyrophosphate dihydrate (CPPD) deposition disease is an inflammatory arthritis induced by calcium pyrophosphate (CPP) crystals and clinically it is called pseudogout. It usually deposits in articular cartilage and in periarticular soft tissues. But no cases of pseudogout in the rotator cuff without cartilage deposition or destruction have been reported so far. We present a case of a 57-year-old woman who was diagnosed as pseudogout with rotator cuff tear.

BACKGROUND: The modified Glasgow prognostic score (mGPS) is a reliable system for identifying patients at high risk of death among patients with soft tissue sarcoma (STS). The scoring systems use a combination of C-reactive protein (CRP) and albumin levels. Although patients with high-grade STS are at risk of metastasis and death, even if their mGPS is 0, the prognostic indicators in these patients are unknown. Therefore, we investigated useful prognostic indicators for survival and the development of metastasis in patients with high-grade STS and an mGPS of 0...
