Flat foot and/or metatarsal primus varus are the major causes of hallux valgus, and it is important to correct these deformities in order to prevent the recurrence of this condition. We demonstrate the clinical and radiological assessment of the correction of hallux valgus, metatarsal primus varus, and flat foot after proximal oblique-domed osteotomy of the(More)
BACKGROUND The surgical results have been reported as poor for advanced osteochondral lesions of the ankle with large subchondral lesions including subchondral cyst. HYPOTHESIS Transplanting an autologous cancellous bone plug from the pelvis to the lesions retrogradely may bring good clinical results for the treatment of advanced osteochondral lesions(More)
Although rarely indicated for hip and knee joint disorders, arthrodesis is still a common surgical procedure for ankle joint disorders such as end-stage degeneration, inflamma­ tion including rheumatoid arthritis and infection, and avascular necrosis of the talus.· Recently, arthroscopic ankle arthrodesis has been performed widely and several satisfac­ tory(More)
We report our clinical findings on 12 tumors (11 patients) successfully resected by partial nephrectomy with a microwave tissue coagulator (MTC) without renal pedicle clamping, including laparoscopic operation in 4 patients. All patients presented with a renal tumor detected incidentally by ultrasonography or computed tomography. The mean size of renal(More)
PURPOSE The purpose of this study was to determine the clinical results of deep-fascial medial and lateral portals in performing endoscopic surgery for plantar fasciitis. METHODS In 10 feet in 8 patients who were treated conservatively for more than 6 months with failure to relieve their symptoms, endoscopic surgery was performed. After the patient was(More)
BACKGROUND Although various tendon repair techniques have been reported to achieve stronger repair, suture failures tend to occur near the knot. We experimentally investigated whether the location of a single core suture knot affects the biomechanical properties of the repair. METHODS Transected bovine tendons (male Japanese black cattle, 24 months old)(More)
PURPOSE The purpose of this study was to investigate the clinical, radiologic, and arthroscopic results of lateral stabilization with reconstruction of the lateral ligaments and cartilage regeneration with arthroscopic drilling for the treatment of moderate osteoarthritis of the ankle with simultaneous lateral instability of the ankle (LIA). METHODS There(More)
BACKGROUND Strong suture material and a firmly tight knot that never loosens are necessary for tendon suture, but the appropriate combination of suture materials and the methods to make a knot are matters of uncertainty. METHODS The tensile strength of four conventional tendon suture materials (Surgilon, Ethibond, Ethilon, PDS II) and newly developed(More)
