The treatment of fractures of the dens is controversial and the major controversy has centered on type II fracture of Anderson and D'Alonzo classification because of its high incidence of nonunion when they were treated by external immobilization like halo apparatus. The posterior arthrodesis of atlas and axis which has been recommended by many authors results in the limitation of rotation of neck. In an attempt to promote bone union and to eliminate functional impairment, the authors have treated 7 consecutive cases of type II dens fracture by direct screw fixation with one or two screws. Minimum follow up period was 15 months(Av. 20mos.). Ages were varied between 23 to 68 years. Amounts of displacement on arrival were more than 4mm in all. Ambulation was started from the day after operation with the external support. Bone union was observed in 6 cases within 3 months without limitation of rotation. One nonunion with losening of screw and one transient dysphagia were observed. The authors believe that the procedure has the advantages in bone union and neck motion, but it requires surgeon's experience and the modification of implant for secure fixation.

Angiosarcoma is rare disease not only in Korea but throughout the world; it is all the more so on the skin. We made an observation on a case of angiosarcoma on the scalp of a 57 year-old man. Noteworthy in this case are: (1) the patient was suffered from a head trauma 6 years prior to onset of the disease, (2) the progress of the disease showed an extreme rapidity accompanied by severe headache intolerable by any medication, (3) no effect was resulted from X-ray irradiation, and (4) the patient survived for 7 months with the disease.

PURPOSE: To avoid prolonged recovery time and scar tenderness in open carpal tunnel release and possible nerve or tendon injuries by bulky instruments in endoscopic techniques, we tried to percutaneously release the transverse carpal ligament using simple, thin instruments. MATERIALS AND METHODS: We performed carpal tunnel release percutaneously through a single small incision on the wrist with curved mosquito and meniscectomy hook knife under general or regional anesthesia in 41 wrists of 27 patients during the last 5 years and followed up for at least one year. Before and after release, endoscopic examinations were done to rule out space occupying lesions or other anormalies and to confirm complete release. RESULTS: According to the Cseuz's criteria, 38 cases (93%) showed excellent or good results, which was compatible to open or endoscopic technique with special instruments and there was no major neurovascular injury except one superficial palmar arch laceration associated with the second palmar incision in complicated case. CONCLUSIONS: From earlier experience, we learned that this simple technique may be used successfully with low cost without any fear of complication.

Although several kinds of instrumentation systems are available for the transpedicular screw fixation in the treatment of spondylolisthesis, the clinical results and the difference between them remdins unclear. In order to study the feasibility of Zielke instrumentation system for that purpose, the author analysed the clinical results of 73 patients with mild or moderate degree of spondylolisthesis who were instrumented with the systems and followed up 25 months in average(Min. 12Ms). The results between the groups with different rod thickness in the system, 3.2mm(20 patients), 4mm(33 patients) and 5mm(20 patients), were compared to study the most appropriate thickness. Reduction of the deformity were done by aid of temporarilly applied Harrington system in 3.2mm group. Inlayed reduction potential coming from the jointing mechanism was utilized in the cases with less than 30% of slippage in 4 and 5mm group. Percentage of slippage was changed from 20% preoperatively, to 4% postoperatively and 6% at the end of follow up. The methods of fusion after reduction and fixation were anterior in 25 and posterolateral in 48. Bony fusion was achieved in all but one with pathological spondylolisthesis. Rod failures were observed in two of 3.2mm and one of 4mm group, and loosening of the joint were developed in three of 5mm group. Clinically, 93% of the patient showed excellent and good results at the end of follow up. From the results, we concluded that the instrumentation is a efficient method of treatment with several advantages in the reduction capacity and the stability of fixation. However, this system has several points in its mechanics that needs to be improved.
