We reviewed the long-term course of the donor-site ankle after vascularized fibula grafts in 13 children. The preventive and therapeutic effects of the tibio-fibular metaphyseal synostosis (T-F synostosis) against valgus ankle deformity, which is one of the postoperative donor-site problems, were evaluated based on three radiologic and clinical parameters.(More)
PURPOSE The purpose of this study was to prospectively evaluate clinical results for open reduction and internal fixation of unstable metaphyseal fractures of the metacarpal and phalangeal bones using a miniature titanium plate. METHODS Fifty-one consecutive patients with periarticular fractures with metaphyseal comminution and displacement were enrolled.(More)
BACKGROUND A variety of outcome measures are available to evaluate physical impairment and disability in patients with knee osteoarthritis, and most physician-rated measures are not validated. The objective of this study was to assess the validity and reliability of an observer-based knee scoring system of the Japanese Orthopaedic Association (the JOA)(More)
Primary soft-tissue coverage for large palmar defects of the fingers is a difficult problem for cases in which homodigital or heterodigital flaps cannot be used. The aim of this study was to explore the vascular and neural anatomy of the midpalmar area to assess the possibility of reverse island flaps from this area. In 24 cadaver hands perfused with a(More)
BACKGROUND We investigated the dynamics of the ulnar nerve during elbow flexion and the relationships between these dynamics and the morphology of the ulnar nerve groove in healthy individuals. MATERIALS AND METHODS Twenty healthy volunteers (40 elbows) underwent ultrasonographic examination of the ulnar nerve at the elbow. We measured the breadth and(More)
BACKGROUND There is no robust evidence for the best treatment practice for metacarpal neck fractures. The purpose of this comparative study was to investigate whether the intramedullary nail or low-profile plate allows for good clinical and radiological results for displaced metacarpal neck fractures. METHODS We prospectively reviewed 30 patients with a(More)
STUDY DESIGN An analysis of lateral radiographs in the upright, flexion-extension position. OBJECTIVES To document and define the differences in cervical flexion-extension kinematics as they relate to changes of alignment in upright cervical lordosis. SUMMARY OF BACKGROUND DATA No previous study has reported the association between sagittal plane(More)
We conducted a biomechanical study of changes in parameters of wrist motor tendons in fractures of the distal radius in 7 cadaveric extremities. Extra-articular distal radius fractures were simulated by distal radius osteotomy and fracture angulation was maintained by external fixators. Eight positions of the distal radius fractures were studied: dorsal(More)
PURPOSE A tear of the triangular fibrocartilage complex (TFCC) is the most frequent soft tissue injury associated with fractures of the distal radius, and repair of the deep ligamentous portion of the TFCC is considered when the tear contributes to instability of the distal radioulnar joint (DRUJ). The purpose of this prospective cohort study was to(More)
