ABSTRACT
PURPOSE: To evaluate the clinical results of modified tension band wire technique using cortical screw for treatment of displaced medial malleolar fractures of the ankle. MATERIALS AND METHODS: From January 2001 to January 2003, 24 patients were treated by modified tension band wiring using cortical screw for medial malleolar fracture. The follow-up period was 12~35 months (average 18 months). There were 13 males and 11 females, and the mean age was 46 years. Fractures were classified by Lauge-Hansen's classification. The results were analyzed by Meyer and Kumler's criteria. RESULTS: There were 13 cases (54%) of excellent, 9 cases (38%) of good, and one case of fair because of limitation of motion of the ankle joint and one case of poor which showed post-traumatic arthritis of the ankle. CONCLUSION: Modified tension band wire technique using cortical screw can be an effective operative method for the treatment of displaced medial malleolar fractures of the ankle.

STUDY DESIGN: A case report and literature review. OBJECTIVES: To discuss pyogenic infections of the facet joints and paraspinal intramuscular abscess that developed after a steroid injection into the facet joint of the lower back. MATERIAL AND METHODS: A 39-year-old man who received a steroid injection to the facet joint, 3 weeks prior to admission, experienced increasing lower back pain and a high fever. RESULTS: Plain radiographs of the lumbar spine showed osteolytic erosion of the articular process at the L3-4 facet joint. On a CT scan, the destructed facet joint was connected to a paraspinal intramuscular abscess. MR images also showed a paraspinal intramuscular abscess on multiplane views. In the operative field, the paraspinal abscess, which extended from 2nd to 5th lumbar vertebrae, was found on the right side, with the L3-4 facet destructed and directly connected to the abscess. Some chalky material, considered to be steroid crystals, was found at the L3-4 facet joint. Drainage, debridement and irrigation were performed. Staphylococcus aureus was isolated from the culture. After surgery, intravenous antibiotics were administered, and the patients' symptoms quickly resolved. CONCLUSIONS: A posterior facet joint injection has its own risks of developing a pyogenic infection of the facet joint. Pyogenic facet joint infections may progress to a paraspinal intramuscular abscess. Surgical drainage is mandatory in cases resistant to antibiotic treatment, with evidence of pus formation on imaging studies.
