The authors have reviewed 19 patients of brachial plexus injury who treated by operative methods at Department of Orthopedic Surgery, Korea University Hospital during the period from January 1989 to February 1994. All of these patients were followed up more than one year and following results were obtained. 1. The whole arm type injury was most common(7 of 19 patient) and supraclavicular lesion(15 of 19 patient) was more dominant than infraclavicular lesion(4 of 19 patients). 2. The neurorrhaphy, nurolysis, nerve grafting, and neurotization were performed for the primary neural surgery and secondary reconstructive procedure consist of musculotendinous transfer and free muscle transfer with neurotization. 3. The followed up period was from one year to four years and six months, average being two years and five months. 4. We have obtained satisfactory results in 12 patients among 19 patients.

Hereditary multiple exostosis (HME) is an autosomal dominant disorder manifested by the presence of multiple osteochondromas. Although the lesions are benign in nature, exostoses are often associated with characteristic progressive skeletal deformity and displaying clinical symptoms such as mechanical irritation or impingement. We present the successful arthroscopic resection in a 24-year-old HME male with impingement syndrome and long head tendon tear of the biceps caused by osteochondroma arising from the distal clavicle.

Subacute osteomyelitis of the patella is a very rare condition and its diagnosis is delayed because of its rarity and variable presentation. This is a report of a case of osteomyelitis of the patella in an adult.

Charcot arthropathy of the foot and ankle is characterized by a combination of sensory, motor and autonomic peripheral neuropathy leading to gross swelling, bony destruction and finally severe bony deformity with joint instability. We report a case of very unstable Charcot arthropathy in ankle joint managed with ankle arthrodesis using fibular strut bone grafting technique.

In this paper, a transfemoral prosthesis with a microprocessor controlled pneumatic knee developed at KOREC is presented. The resistance of the knee is changed automatically via a microprocessor as the amputee's gait speed changes, so that the prosthetic side of the amputee can follow the sound limb. Gait analysis has been conducted to evaluate the performance of the developed prosthesis and the improvement of the gait pattern including the gait symmetry was observed.

In this study, an experiments and numerical simulation of a three chamber pneumatic cylinder for an intelligent AK-knee prosthesis is performed. The cylinder has a variable orifice which can be controlled automatically through a microprocessor controller as needed while amputee gaits. In the experiment, the cylinder was driven by a cam whose trajectory of simulates the normal gait and axial forces of cylinder with different of orifice opening was measured. The numerical simulations was based on thermodynamic and fluid mechanical consideration. The experimental results and the numerical results were in good agreement.

In general, the long head of the biceps brachii originates from the superior glenoid labrum and the supraglenoid tubercle, crosses the rotator cuff interval, and extends into the bicipital groove. However, rare anatomic variations of the origins of the long head have been reported in the past. In this report, we review the clinical history, radiologic findings, and arthroscopic identifications of 3 anatomic variants of the biceps tendon long head. As the detection of long head of biceps tendon pathology during preoperative radiologic assessment can be difficult without prior knowledge, surgeons should be aware of such possible anatomic variations.
