Free Vascularized Musculocutaneous Flap Transplantation for Tissue Defect in Forearm.

Orthopedics & Traumatology (1999)

Teiji Kato Kensuke Yonemura Kimiaki Nishida Toshitake Yakushizi Toru Tsuchida

Two cases of forearm tissue defects were treated by free vascularized musculocutaneous flap or free vascularized muscle flap transplantation. Case 1 who received a press injury and had an infection in the left forearm suffered complete median nerve palsy. Free vascularized rectus abdominis flap (9×12cm) was transplanted following debriedement of infected tissue. Thirteen months later, this patient has returned to his original job. Case 2 received two operations against soft tissue sarcoma in the right forearm before she visited our hospital. Tissue defect following wide recection of synovial sarcoma in the right forearm was reconstructed by free vascularized latissimus dorsi musculocutaneous flap (24×15cm). The right hand of this patient is useful with a simple elbow orthosis seven months after the last operation.

Solitary bone cyst in hamate bone - A case report.

Orthopedics & Traumatology (1989)

Tatsuaki Tsuchiya Kensuke Yonemura Issei Higashi Kouichi Ieiri Katsumasa Takagi

Solitary bone cyst is a common lesion at the proximal metaphysis of the long bones such as the humerus and femur. It also occurs in other bones although low frequency. We recently experienced a 19-year-old girl with a bone cyst in the hamate bone. She complained of pain on motion of her wrist. CT clearly demonstrated the lesion in the bone. Bone filling was performed as surgical treatment. This is an interesting case since the occurrence in a carpal bone is considerably rare.

Effects of Tranexamic Acid and Drain Clamping Method on Post-operative Blood Loss in Total Knee Arthroplasty

Orthopedics & Traumatology (2010)

Tateki Segata Takeshi Yamashita Katsuya Iwamoto Kensuke Yonemura Issei Ishii

人工膝関節置換術における出血対策として様々な方法がある．我々は2006年5月よりドレーンクランプ法（DC法）を行ってきた．2008年7月よりトラネキサム酸（TA）2gの局所使用をDC法と併用し行ってきた．それらの術後出血量について検討し報告する．対象は2008年4月1日～2009年2月28日の間に施行したTKA症例全66膝のうち同日施行両側TKA症例6膝とDC法単独セメントレスTKA症例3膝を除外した57膝．これらをDC法単独セメント使用群（A群），TA併用・セメント使用群（B群），TA併用・セメントレス群（C群）にわけ検討した．患者背景としてA群で有意に手術時間，駆血時間が長かった．A群に対しB群では術後3日目Hb値，Hb変化量および全出血量で有意差を認め，A群に対しC群では術後出血量，全出血量およびHb変化量で有意差を認めた．トラネキサム酸の局所併用療法は有効な止血法である．

Functional Results of Limb Salvage Operations Using a Prosthesis for Malignant Bone Tumors.

Orthopedics & Traumatology (1992)

Kensuke Yonemura Shinji Izumi Teiji Kato Tatsuaki Tuchiya Yasuyuki Abe

Limb saving by prosthesis is a standard method of surgery for treatment of malignant bone tumors. We have had experience of 12 cases with a follow-up 12-72 months.The functional results according to the MSTS evaluation system were good in 6 cases and fair in 6. In each parameter, muscle strength was evaluated as poor in almost all patients with proximal Pemoral and tibial lesions. These results sugges that inprouenent is heeded in the reconstruction and attachment of hip abductors and patellar ligament.

Osamu Mori Keizou Morisawa Kensuke Yonemura Katsumasa Takagi Toshio Kitagawa

It is not rare for patients with malignant lymphoma to present to an orthopedic surgeon.Some outpatients have complaints such as tumors of soft parts, pathologic fracture, abnormal bone pictures on X-ray, or symptoms of spinal cord compression.For this report, we investigated patients with malignant lymphoma presenting with bone lesions or neurological symptoms since 1976.

A Case Report Chondrosarcoma with Multiple Bone Metastases without Pulmonary Involvement.

Orthopedics & Traumatology (2002)

Hiroaki Nishioka Kensuke Yonemura Toshitake Yakushiji Teiji Kato Yasuhiro Kawazoe

In this study, we report a rare case of chondrosarcoma with multiple bone metastases withouot pulmonary involvement.A 47-year-old man underwent wide excision for chondrosarcoma of the right seventh rib. After a 51 month excellent control period of the primary tumor, a second tumor of the left scapula was identified. Subsequently additional metastases were noted in the right femur and right ilium. All bony involvement, scapula, femur and ilium were resected with a wide margin and bone defect of the right femur was reconstructed with autoclaved bone graft. Microscopical examination showed that all specimens of the right seventh rib, left scapula, right femur and right ilium are of the same histologic type without change in the histologic grade. The patient is still alive, and to date has had no evidence of lung metastasis.

Reconstructions of Mobilization for Advanced Elbow joint Osteoarthritis.

Orthopedics & Traumatology (2003)

Yoshiko Nishi Teiji Katou Toshitake Yakushiji Yasuhiro Kawazoe Naonori Cibana

Mobilization or total elbow arthtroplasty is indicated for advanced elbow joint osteoarthritis in elderly people. While patients with rheumatoid arthritis and/or those who are retired are suited for total arthroplasty, those still engaged in hard physical work are not. Three patients with limited elbow flexion less than 90 degrees, ages 62, 60, and 73, were treated by mobilization. Three returned their form work without any pain and instability in the elbow joint. Limited elbow flexion, 83, 75, and 80 degrees before operation improved to 140, 122, and 115 degrees three weeks post operatively. Even if advanced, severely deformed elbow joints are observed in elderly patients, and mobilization is recommended for those involved in work requiring hard labor.
