Most radial head fractures occur as the result of low-energy mechanisms, such as a trip or fall on the outstretched hand. These fractures typically occur when an axial load is applied to the forearm, causing the radial head to hit the capitellum of the humerus. Good results are shown with nonsurgical treatments for Mason type 2 fractures. However, if there is a limitation of elbow joint exercise or displacement of more than 2 mm, an operative treatment should be considered. We treated two patients with arthroscopic assisted bioabsorbable screw (K-METâ„¢; U&I Corporation, Uijeongbu, Korea) fixation for radial head fractures to prevent complications of open reduction and minimize radiation exposure.

PURPOSE To investigate the results of arthroscopically assisted reduction of intraarticular fracture of distal radius with percutaneous K-wires and external fixation. MATERIALS AND METHODS We reviewed 12 intraarticular distal radial fractures of 11 patients treated arthroscopically assisted reduction in Orthopedic Department of Sung-Ae hospital between January, 2001 and August, 2001. The mean length of follow-up was 14 months. Analysis of them revealed that B3 was 1 case, C2 4 cases and C3 7 cases according to the AO classification. All cases were treated by 2.7 mm arthrosopic devices and percutaneous K-wires pinning with external fixation, but additionally invasive reductional technique was not used. We removed the osteochondral flap in the joint space and detected the carpal ligaments and triangular fibrocartilage complex tears but not treated. The K-wires were removed at 4 weeks, external fixation was 7 weeks, respectively. RESULTS The mean active range of movement in the affected wrist was total arc of the flexion-extension 72% of the opposite side. Radiographically mean volar tilt, radial inclination and radial length were 5.7 degrees, 22.4 degrees, and 12.3 mm. The mean articualar step-off was 2 mm or less. Post-operative compartment syndrome and fracture collapse were not occured during follow-up period.
According to the Gartland and Werley demerit-point system, eleven cases were a excellent or good and one was a fair result. CONCLUSION Arthroscopically assisted fixation is a useful method for reducing the soft tissue injuries and preventing the articular surface incongruency by anatomically reduction in cases of intraarticular comminution.

A variety of surgical modalities for fractures of patella have been described. We used arthroscopic reduction and percutaneous screw fixation for six cases of longitudinal fracture of patella. Ages of the patients ranged from 25 to 33 years. the postoperative regimen was one week long leg splint for reducing the pain, followed by continuous passive range of motion exercise of the knee including active one and quadriceps strengthening exercise until the full range of motion was gained, with progressive partial to full weight bearing with crutches. The follow-up period was from 12 to 54 monhts. Results were assessed subjectively and objectively with retrograde study. The full range of knee motion was recovered from 20 to 35 days postoperatively, The radiographic bone union was achieved from 31 to 42 days. And all patient had good results according to Lysholm and Gillquist scoring system. We had no experience of complication except one which is prominence of screw end. So, we believed that the arthroscopic reduction and percutaneous cannulated screw fixation for longitudinal fractures of patella is the useful surgical method.
Meyers and Mckeever proposed a classification of intercondylar eminence fractures based on the degree of displacement. Zaricznyj added type IV comminuted avulsion fracture. Type III and IV of tibial spine fractures are considered an indication for surgery. The purpose of this study is to evaluate the result of arthroscopic treatment for displaced intercondylar eminence fractures. In all of the cases, the displaced fragments were reduced arthroscopically in effective, and fixed by K-wires, pull-out sutures or pull out wiring. At last follow-up above 12 months, all 22 cases(100%) were evaluated as above good by Meyers and Mckeever criteria.
