PURPOSE: The purpose of this study is to evaluate the possible relationship between femoral intercondylar notch stenosis and ACL injury according to gender with retrospective analysis of knee MRI. MATERIALS AND METHODS: The study was based on 260 cases of knee MRI (except the cases of combined colleteral ligaments injury and fracture) between the ages of 18 and 50 years from March 1995 to March 2001. All cases were divided into three groups : group 1 consisted of knees 94 cases that were nor-mal, group 2 consisted of knees from 72 cases that had a contact ACL injury, group 3 consisted of knees from 92 cases that had a non contact ACL injury. We measured the notch height, notch width at the point of 1/3, 2/3 of notch height, notch angle, lateral angle with coronal section. Each measurements of three groups were compared with gender and for statistical significance using the ANOVA test. RESULTS: The mean notch angle was 48.2 +/-6.7 degrees for men and 47.1 +/-1.2 degrees for women in group 1, 48.7 +/- 6.5 degrees for men and 48.7 +/-1.2 degrees for women in group 2, 47.4 +/-6.5 degrees for men and 47.3 +/-1.5 degrees for women in group 3. The mean notch width at the point of 1/3, 2/3of notch height were 18.6 +/-2.4 mm, 15.3 +/-2.4 mm for men and 16.9 +/-2.4 mm, 14.2 +/-2.4 mm for women in group 1, 18.2 +/-2.4 mm, 15.2 +/-2.4 mm for men and 16.7 +/-2.4 mm, 13.9 +/-2.4 mm for women in group 2, 16.8 +/-2.4 mm, 13.9 +/-2.4 mm for men and 15.7 +/-2.4 mm, 13.4 +/-2.4 mm for women in group 3. Statistically significant differences were found between sexes in group 3 in regard to notch width at the point of 1/3, 2/3 of notch height, notch angle(<0.05). CONCLUSION: Stenosis of femoral intercondylar notch may be a factor of ACL injury. So preoperative measurement of femoral intercondylar notch may be necessary to determine the amount of notchplasty degree in ACL reconstruction.

Purpose: To analyze the causes and to prevent dislocations of the hip joint that occur in patients who underwent revisions of total hip arthroplasties by changing only the polyethylene liners and femoral heads, subsequent to primary total hip arthroplasties. Materials and Methods: We evaluated 28 patients who underwent acetabular component revisions of total hip arthroplasties subsequent to primary total hip arthroplasties. The average age of the patients was 55 years old and all 28 patients had operations through the posterolateral approach. In 17 of the cases, the acetabular cups, polyethylene liners, and femoral heads were changed; in 10 cases, just the polyethylene liners and femoral heads were changed; and in 1 case, only the polyethylene liner was changed. Results: We observed 7 cases of hip dislocations that occurred among a total of 28 cases after revisions of total hip arthroplasties. In all 7 cases, the polyethylene liners and femoral heads were changed, but not the acetabular cups. In additional, in all 7 cases of dislocation, the patients were non-compliant and started weight-bearing prematurely after revisions of the total hip arthroplasties Conclusion: We observed new dislocations in the 7 cases in which the polyethylene liners and femoral heads were changed. The main reasons were inadequate soft tissue tension and hip joint laxity. Therefore, it is necessary to increase the neck length, use elevated rim polyethylene liners, readjust the acetabular cups to their optimal positions, and apply hip abduction braces to patients early after revision of total hip arthroplasties in order to lessen the danger of dislocations.

Migration of an implantable port catheter tip is one of the well-known complications of this procedure, but the etiology of this problem is not clear. We describe here a case of migration of the tip of a port catheter from the right atrium to the right axillary vein in a patient with severe cough. Coughing was suggested for this case as the cause of the catheter tip migration. We corrected the position of the catheter tip via transfemoral snaring.

Supracondylar fracfture of the humerus is the most common fracture about the elbow joint in children. Early accurate reduction is very important to obtain good results. The authors reviewed 44 cases of supracondylar fractures treated at Inje Universsity Pusan Paik Hospital from January 1986 to December 1990. Average follow-up time was 1 year 6 months. The results were as follows; 1. Thirty cases were treated with closed reduction and percutaneous pinning, ten with manipulation and cast immobilization, three with skeletal traction and the rest one with open reduction and internal fixation. 2. If there was a difference of the angle within 10-degree in post-reduction X-ray, deformity did not follow at the last follow-up. 3. The common formula was that a change of 5-degree in Baumann's angle corresponded to a 2- degree change in the clinical carrying angle. 4. Baumann's angle did not change between that of initially accepted and that of the final follow up X-ray. So, the authors recommend post-reduction measurements of the Baumann's angle as the adequancy of reduction of supracondylar fractures in children.

Bone defect of the long bone continues to challenge orthopedic surgeons. It is usually very difficult to obtain union. Ilizarov ext. fixation has recently gained popularity as a multifactorial approach to the management of tibial bone defect because nonunion, bone defects, limb shortening, and deformity can all be addressed simultaneously with the Ilizarov apparatus. From February 1992 to May 1993 at the department of orthopedic surgery, Inje University Pusan Paik Hospital, 9 patients aged from 8 to 37 years were treated for tibial bone defect. The causes were open comminuted fractures with initial bone loss and bone defect after removal of infected necrotic bone. Bony defect size was ranged from 2cm to 14cm, averaging 7.2cm. Bony defects were gradually closed by the Ilizarov's internal bone transport technique, and final equalization of leg length discrepancy was achieved by means of external lengthening technique. Soft tissue defects were treated with secondary closure, split thickness skin graft, and muscle flap. The average healing index was 42.8 days/cm. According to Paley's classification the complications were developed as follows; The problem included pin tract infection(9), knee flexion contracture(4), and intractable pain(1), the obstacles included delayed union(3) and premature consolidation(1), the complication included nonunion(9) and equinus ankle(1). At an average 1 years follow up, according to Paley and Catagnl's classification, body and functional results were either excellent or good in 7 cases. So, we recommend that Ilizarov technique is very useful treatment for open fracture with bone loss, bone defect after removal of infected necrotic bone and limb shortening.

Background: Teriparatide is an effective anabolic agent used in the treatment of severe osteoporosis. In addition, it is also used to promote fracture healing. The purpose of this double-blind randomized controlled trial was to evaluate the influence of weekly teriparatide administration on bone formation in hip fracture patients. Methods: The control group (n = 41) was composed of patients treated with normal saline other than teriparatide, and the teriparatide group (n = 51) consisted of patients who received weekly teriparatide. Bone turnover markers, C-terminal telopeptide (CTx) and osteocalcin (OC), were assessed through blood tests at the initial hospital visit and 3-month, 6-month, and 1-year follow-ups. Dual-energy X-ray absorptiometry was performed 5 days postoperatively and at 1-year postoperative follow-up. The degree of fracture union was evaluated by comparing the radiographic union scoring system for hips using Radiographic Union Score for Hip (RUSH) scores between the two groups at 3 months, 6 months, and 1 year after surgery. Results: Evaluation of the rate of change in bone mineral density over 1 year showed that the lumber bone mineral density increased by more than 7% in the experimental group. The control group did not show a difference between the CTx and OC at 6 months, but the difference between the CTx and OC values was large at 6 months in the experimental group. The mean RUSH score was significantly different between the control group and the experimental group: 12.105 and 15.476, respectively (p = 0.004), at 3 months and 18.571 and 22.389, respectively, at 6 months (p = 0.006). Conclusions Weekly use of teriparatide improved fracture healing, bone formation, and clinical outcomes at 1 year after hip fracture surgery by the anabolic window effect.
