Deep Submuscular Parosteal Angiomyxolipoma in a Child / 대한골관절종양학회지

Angiomyxolipoma is a rare variant of lipoma, which is described by Mai, 1996, at first. The nine cases of which have been reported to date. Microscopically, the lesion consists of adipose tissue with the paucicellular myxoid areas and fat tissue with numerous thin, dilated, and congestive blood vessels. The reported cases mostly located to the superficial layer on the scalp, subungual, extremities in adults. We report one case of angiomyxolipoma located in the submuscular and parosteal area in the distal femur around knee joint in a child.

Interposition Arthroplasty with Pectoralis Major Muscle Transfer for the Shoulder Arthropathy: 2 Cases Report

Interpostion arthroplasty with allograft has been known as a useful option for the shoulder arthropathy, but it has a limitation to immune response. We performed the pectoralis major muscle transfer for shoulder arthropathy. From January 2007 to December 2007, we performed the pectoralis major muscle transfer in 2 patients. They were 1 man and 1 woman, and the mean age of the patients was 70 years (range, 65 to 75). The average follow-up after surgery was 13 months (range, 12 to 14). We analyzed the clinical results by the American Shoulder and Elbow Surgeons (ASES) Score, and evaluated the pain by Visual Analogue Scale. The level of pain reduced from a preoperative average of 10 to a postoperative average of 1. The ASES scores increased from a preoperative mean of 9 to a postoperative mean of 58. These results indicated that interposition arthroplasty with the pectoralis major muscle transfer is a reliable treatment method for the shoulder arthropathy improving shoulder pain, and patient satisfaction.

Non-Familial Osteopoikilosis around the both Hip Joints: a Case Report

Osteopoikilosis is an osteosclerotic dysplasia of an unknown origin, and this malady is both extremely rare and hereditary and sporadic in nature. It is sometimes asymptomatic and incidentally diagnosed with radiologic images. A familial history and concomitant disease might also be present. In this study, we report on a 31-year-old woman who suffers from pelvic pain and she was diagnosed as having osteopoikilosis around both hip joints by the radiological images. We also review the relevant medical literature.

The Effect of Prophylactic Cable Fixation for Prevention of Femoral Fractures in Hemiarthroplasties

PURPOSE: The purpose of this study was to assess the effect of a prophylactic cable fixation for prevention of femoral fractures in cementless bipolar hemiarthoplasties. MATERIALS AND METHODS: Forty-eight cementless bipolar hemiarthroplasties with prophylactic cable fixations on the femur were performed in patients >65 years of age between January 2004 and August 2008 (group 1). The control group which did not undergo prophylactic cable fixation included 48 cases (group 2). The mean age was 75.4 years (group 1) and 73.6 years (group 2). The patients were followed up for an average of 19.1 (group 1) and 18.3 months (group 2). The intra-operative fracture rates were compared. Additionally, operative time, estimated blood loss (EBL), and length of hospital stay were compared. Radiologic assessment for stem stability was performed. Clinical assessment was evaluated by the thigh pain and Jensen's functional score, and Parker & Palmer's mobility score. RESULTS: There was no fractures in the cabled group (1), and 4 fractures (8.3%) in the control group (2; p=0.041). The mean operative time was 172 minutes (1) and 162 minutes (2), the EBL was 866 cc (1) and 855 cc (2), and the duration of admission was 36 (1) and 35 days (2), respectively. Radiologically, subsidence was 1.59 mm (1) and 1.67 mm (2). Clinically, one (1) and two (2) thigh pains were recorded and the functional score of Jensen was 2 (1) and 2.2 points (2), and the mobility score of Parker and Palmer was 5.2 (1) and 5.3 points (2), respectively. CONCLUSION: Prophylactic cable fixation is effective for reducing intra-operative femoral fractures.
