RESUMEN
PURPOSE: To evaluate the clinical results of displaced transverse patella fractures which were treated with figure-eight wiring by means of parallel cannulated screws. MATERIALS AND METHODS: Ten patients who had displaced non-comminuted transverse patella fractures were seen between August 1998 to March 2000 and then followed up for more than one year, were prospectively evaluated with regard to their clinical and radiologic results. RESULTS: Clinical union occurred at an average of eight weeks and radiologic union at twelve weeks. Clinical results were evaluated at six months and one year postoperatively. The flexion contracture was 3.3degrees, the further flexion was 127.6degrees At six months the flexion contracture was 2degrees, and the further flexion was 135degrees at one year. Functional results according to the Wilkinson classification system were excellent in 8 cases, good in 2 cases at six months excellent in 9 cases, and good in 1 case at twelve months. There was no soft tissue irritation caused by the wire and screw, loosening or an implant migration. CONCLUSION: Cannulated screw fixation and figure-eight wiring is one of the useful methods for the repair of displaced transverse patella fractures.

PURPOSE: To evaluate the chronological change of serum anti-type II collagen antibody level according to the type of immunoglobulin (i.e. IgG, IgM) in chronic arthritic patients. MATERIALS AND METHODS: The serum levels of anti-type II collagen antibody were determined in three groups (control, degenerative arthritis and rheumatoid arthritis) with ELISA method. In each person, the serum levels of antibody IgG, IgM against human, bovine and chicken type II collagens were determined separately. RESULTS: Since correlation coefficients of ELISA showed high values except in the case of denatured human collagen, ELISA test is regarded as reliable. In terms of denatured human collagen, no constant denaturation pattern induced variable results. With regards to chronological changes, there was no change of IgG titer in all three groups. IgM titer of control group was not varied according to time change. But IgM titer of arthritis group changed from time to time. Chronological changes of antibody titers depended on the types of antigen. In case of human collagen, there were changes of antibody titer in the degenerative arthritis and rheumatoid arthritis groups. And in the case of bovine collagen, change of antibody titer was observed only in the rheumatoid arthritis group. CONCLUSION: Chronological change of IgG titer was not observed in the arthritis group but IgM titer changes are observed in that group. Thus, it might be a topic of future research to evaluate the relationship between the chronological change of IgM antibody and disease aggravation.

Although a popliteal cyst is most commonly identified as an asymptomatic mass occurring just below the popliteal fossa, the fluid may further extravasate into a deep compartment, causing compression with symptoms of local pain and tenderness. When the popliteal vein is compressed by a popliteal cyst, it may develop the symptom simulating the deep vein thrombosis, when the popliteal artery is compressed, it may develop the symptom simulating the ischemic pain and intermittent claudication. It is unusual for popliteal cysts to involve a nerve. When such does occur, it usually involves the tibial nerve, very rarely the peroneal nerve. It is important to diagnose a popliteal cyst early and to differentiate it from a ganglionic cyst, thrombophlebitis or a popliteal aneurysm, to effect optimal therapy and to obviate a potential neuropathy. We are now reporting a case of a thirty four-year-old male who had a popliteal cyst causing tibial nerve compression.

A subperiosteal ganglion has been very rarely reported, since Ollier reported first one in 1864. A subperiosteal ganglion is produced by mucoid degeneration and cyst formation within the periosteum, which results in cortical erosion. The characteristic plain radiolographic appearance of irregular cortical erosion and scalloping, with reactive periosteal bone spicules, has been considered pathognomonic of subperiosteal ganglion. Magnetic resonance imaging is performed to further characterize the soft tissue component of the mass. As in our patient, the characteristic signal intensities of magnetic resonance imaging are especially useful in identifying the lesion as a ganglion and in defining the lobular nature and the anatomical extent. We report here the case of a 35-year-old female who had a sudperiosteal ganglion of the distal radius.

Isolated dorsal dislocation of the trapezoid is an unusual injury. In 1990 Ostroski found only 15 cases of dorsal dislocation of the trapezoid in the world literature. The trapezoid is a wedge-shaped bone with the larger dorsal and smaller volar surface area, and stabilized by strong palmar ligaments. Therefore the dislocation of the trapezoid is produced hy a violent force against the dorsum of the hand on a rigid object and often associated with other injuries of the hand. The diagnosis is often missed or delayed perhaps secondary to the difficulty in interpreting the X-ray if you have not kept in mind. Several therapeutic modalities are performed from the collected experience of the authors reporting this injury. A rare example of an isolated dorsal dislocation of the trapezoid bone is described.

Injuries to the menisci occur in a variety of ways, most commonly with a twist, pivot, squat, or valgus stress to the knee. Tear patterns are classified to longitudinal, horizontal, or transverse features according to the mechanism of injury. Work-related meniscal tear usually occurs with a repetitive usage of the foot, hence it can be classified as a cumulative traumatic disorder. We found a 47 year-old female worker who had been taking charge of repetitive foot-switch stepping for 8 years. She suffered from pain in the right knee since 5 months ago. Tenderness along the medial joint line of the right knee was observed and pain was aggravated with full flexion of the right knee. On magnetic resonance imaging, high signal intensity was observed at the posterior horn of the medial meniscus of the right knee. Degenerative longitudinal and transverse complex tear in the medial meniscus was observed on arthroscopy. Arthroscopic partial meniscectomy was performed. We surveyed the work process and the health status of co-workers. It turned out that the work process was compatible to injure the meniscus and nine out of fourteen co-workers(64.3%) complained pain of the knee. No other factors related to her meniscal tear could be found except for the situation at her work. Therefore, we conclude that meniscal tear is related to the repetitive stepping of foot switch.
