The Journal of the Korean Orthopaedic Association.2001;36(6):531-536.

PURPOSE: To review the results of resections of heterotopic ossification around the hip in patients with central nervous system injuries. MATERIALS AND METHODS: Heterotopic ossification was resected in ten hips of eight patients and followed for at least one year. Average age was 38.1 years (range, 21-56 years). We reviewed the charts and the radiographs for overall patient function, location of the lesion, radiographic evidence of maturation and any recurrence. Heterotopic ossification was resected regardless of the result of bone scan. RESULTS: All patients showed improved function. Three minimal recurrences and one moderate recurrence were identified at the last follow-up radiography, but the range of motion had not decreased due to recurrence. CONCLUSION: Severe heterotopic ossification around the hip in patients with spastic paralysis was resected, and it was found that the range of motion was improved in all patients and that the chance of recurrence was minimal, even though the bone scan showed hot uptake on the bone scan.

The Journal of the Korean Orthopaedic Association.2001;36(6):593-599.

PURPOSE: To analyze congenital anomalies, especially musculoskeletal anomalies, in patients with VATER association. MATERIALS AND METHODS: Fifteen patients who were admitted to our hospital from Jan. 1990 to Dec. 1997, and with more than three of the major criteria of VATER association, were included in this study. Major criteria were vertebral anomalies, imperforated anus, tracheoesophageal anomalies, radial side anomalies, renal anomalies and congenital heart anomalies. RESULTS: Seven boys and 8 girls with VATER association were included. The follow-up period, except for 4 cases who died, was 6 years and 8 months on average (from 2 years and 3 months to 12 years and 7 months). Twelve patients had congenital heart disease, and 11 patients had tracheoesophageal anomalies and imperforated anus, 8 had vertebral anomalies, and radial side anomalies and renal anomalies were detected in 6 patients each. Congenital rib anomalies were the most common. CONCLUSION: Orthopedic surgeons who address vertebral or radial side anomalies in patients with VATER association need to predict other possible anomalies and should have enough knowledge to treat these conditions.

Effects of bFGF on the Regeneration of Non-vascularized and Vascularized Nerve Graft in Rats.

The Journal of the Korean Orthopaedic Association.2001;36(6):631-640.

PURPOSE: This paper compares the effect of basic fibroblast growth factor (bFGF) on the regeneration process in non-vascularized nerve grafts and vascularized nerve grafts in the case of poor recipient bed condition. MATERIALS AND METHODS: One hundred and six Wistar rats were divided into 4 groups; CNG (Conventional nerve graft, n=25), CNG-F (Conventional nerve graft treated with bFGF, n=27), VNG (Vascularized nerve graft, n=25), and VNG-F (Vascularized nerve graft treated with bFGF, n=29). Each type of nerve graft was 6 mm in length, and inserted into a silicone tube, to prevent revascularization from the recipient bed. The bFGF solution (10 L, 400 ng/mL) was injected into the silicone tube in the CNG-F and VNG-F groups, and collagen solution (10 L, 2.4 mg/mL) was injected in the CNG and VNG groups. RESULTS: The latency period delay decreased and the amplitude of motor action potential, the number of myelinated axons, and the number of large myelinated axons (over 5 m in diameter) increased significantly in the CNG-F group versus the CNG group 4 weeks after the operation. The amplitude of the motor action potential, the mean diameter, the number of myelinated axons, and the number of large myelinated axons increased significantly in the VNG-F group versus the CNG-F and the VNG groups 2 and 4 weeks after the operation. CONCLUSION: These results suggest that vascularized nerve graft treated with bFGF is one of the best ways of repairing the segmental peripheral nerve defect.

Clinical Application of Unilateral-Ring Hybrid Fixation Using DynaExtor(R).

The Journal of the Korean Orthopaedic Association.2001;36(6):623-629.

PURPOSE: We have used a hybrid fixation, in which DynaExtor(R) and Ilizarov rings are connected each other with special connectors. Here, we report upon the technical tips learned and the clinical outcomes of the first twenty five consecutive cases treated using this method. MATERIALS AND METHODS: Between May 1997 and December 1999, 25 patients were treated using hybrid fixation aimed at simple lengthening (8 patients), concomitant deformity correction and lengthening (12), deformity correction alone (3), and fracture fixation (2). RESULTS: In the group requiring simple lengthening, the healing index (H.I.) was 38.3 day/cm (23.6-66.8 day/cm). For concomitant deformity correction and lengthening, the mean amount of angular correction was 33.8degrees (15-75degrees) and the length gain, 4.7 cm (2.2-8.9 cm). For deformity correction alone, the amount of angular correction was 50.1degrees (15-120degrees). For fracture fixation, the mean external fixation time was 59.5 days (26-93 days). Complications included mild pin-tract infection in 8 patients, a temporary stiff joint in 5, and equinus of the foot and delayed union in one patient each. CONCLUSION: The DynaExtor(R) hybrid-fixation system is an effective and convenient method that can be selectively applied to cases that need deformity correction, lengthening, or fixation of the long bone.

The Journal of the Korean Orthopaedic Association.2001;36(6):607-611.

PURPOSE: The aim of this study was to determine differences in the specific collagen types of the transverse carpal ligament (TCL) in patients with carpal tunnel syndrome (CTS) and a control group without CTS. MATERIALS AND METHODS: Surgical specimens from 19 dissected TCLs in patients with idiopathic CTS and 5 controls without CTS were taken (1x1 cm2). We analyzed the manifestations of collagen types I and III by immunohistochemical staining. RESULTS: We found a homogeneous manifestation of type I and III collagens in the control group. However, in CTS patients, type III collagen was sporadically found around the perivascular and pericellular area, and type I collagen showed no definite differences between the two groups. The cellularity in CTS patients was much lower than that in the control group. CONCLUSION: The TCL in CTS patients shows reduced manifestation of type III collagen and less cellularity. These intrinsic changes may play a role in the different manifestations of collagen types in TCL.
