The femoral neck fractures in children remain an unsolved problem because of lack of the optimal treatment followed by unpredictable, serious complications. Since the first trial of muscle pedicle bone graft by Judet(1962), Meyers et al(1973) refined and promoted this method for nonunion and as a primary procedure, and Baksi(1983, 1986) expanded its indication to post-traumatic avascular necrosis of the femoral head. Two cases of avascular necrosis and Two nonunion cases treated by quadratus femoris muscle pedicle bone graft at the Chonbuk National University Hospital from Jan. 1986 to Jun. 1988 were reported. The age of the patients varied from 6 to 16 years ; Follow-up ranged 6 to 29 months ; all cases were displaced transcervical fracture. In according to Ratliffs assessment, three cases showed satisfsctory results and one poor.

There have been increasing interests of diabetes in the realm of plastic surgery due to problems like foot ulcer as a complication, delayed wound healing or higher failure rates of flap surgery. Main pathology in diabetes is microvascular compromise as well as metabolic derangements. The disturbance in microvascular circulation results in ischemic environments in the body and acts as a main factor that determines the limit of reconstructive or aesthetic plastic surgery. A useful method to overcome such problems is the use of hyperbaric oxygen therapy, which is known to be effective in the treatment of ischemic skin ulcer or osteoradionecrosis. However, there have been few studies on the survival of diabetic random skin flap or the effects of hyperbaric oxygenation directed to increase survival of such flap. In our study, we supposed that the survival of diabetic random skin flap was diminished owing to compromised microvascular pathology and blood rheology, and metabolic derangements, so we hypothesized that hyperbaric oxygen therapy has both reversible and irreversible effects on the survival of ischemic random skin flap in Streptozotocin-induced diabetic rats. Increase of local transcutaneous oxygen concentration, O2 affinity in blood and dysmorphogenesis of red blood cells are reversible and relatively short-term effects and promotion of neoangiogenesis is irreversible or long-term effects. We intended to confirm that hyperbaric rats and to compare the effects between preoperative and postoperative hyperbaric oxygenation on the survival of such flap. And we expect the additional effects of hyperbaric oxygenation on metabolism in diabetic rat, such as lowering the blood glucose level and solving the arrested weight gain. We divided Streptozotocin-induced diabetic rats into three groups: the first was non-treatment diabetic group, the second was preoperative hyperbaric oxygen treated diabetic group(100% O2, 2 atm, 90min, 15sessions, twice a day), and the third was postoperative hyperbaric oxygen treated group(100% O2, 2atm, 90min, 15sessions, twice a day). After elevation of random skin flap on dorsum of diabetic rats, we evaluated the extent of flap survival by measuring the necrotic areas at 3rd, 7th, 10th, and 13th postoperative days. At that time, we intended to evaluate both effects on flap survival by preoperative and postoperative hyperbaric oxygen therapy. As a result, flap survival of non-treated diabetic group was 41% at 13th postoperative days. In diabetic groups with preoperative and postoperative hyperbaric oxygen therapy, flap survival were increased to 64.6% and 62.4% respectively. Diabetic groups with hyperbaric oxygen therapy have a tendency of meaningful decrement in blood glucose level. However, there were no meaningful differences between preoperative and postoperative hyperbaric oxygen therapy. Hyperbaric oxygen therapy has no effective correlations with body weight changes. We conclude that hyperbaric oxygen therapy has some useful effects on the survival of diabetic random skin flap.

Purpose: The goal of study was to evaluate the clinical and radiographic performance of the proximal modular cementless femoral stem for use in revision total hip arthroplasty. Material and method: Fifty seven patients (57 hips) were followed for longer than 24 months or up to 8.4 years after performing revision total hip arthroplasty with using the proximal modular cementless femoral stem between January 1997 and December 2002. The preoperative diagnosis included 45 cases of aseptic loosening, 5 cases of septic loosening (re-revision operation), 6 cases of periprosthetic fracture and 1 case of recurrent dislocation. The bone deficiencies were classified according to the Paprosky classification: there were 27 cases of Type I and II, 19 cases of Type IIIA, 9 cases of Type IIIB and 2 cases of Type IV. Results: The average Harris hip score improved from 47 to 87.6. Clinically satisfactory results were noted in 50 patients (87.7%). Radiographically, distal stable fixation was observed in 54 patients (94.7%). Intraoperative complications included two greater trochanteric fractures and two proximal femur fractures. Postoperative complications included 5 femoral stem subsidences (2hips< 5mm, 3 hips>20mm), 4 deep infections, 2 non-unions of the greater trochanter and the osteotomy site and set screw dissociation was noted in 1 case. 5 proximal component changes were done due to progressive subsidence in two cases, non-union at the osteotomy site and trochanteric displacement in two cases and set screw dissociation in one hip. For the infection cases, the proximal segment was removed and re-revised with a 2nd stage operation. (Ed note: check this.) The subsidence of the femoral stems was showed in 3 Paprosky grade IIIA cases and in 2 cases of grade IIIB or more. There was no postoperative periprosthetic fracture observed at the last follow-up. Conclusion: Revision total hip arthroplasty using the proximal modular cementless femoral stem showed good results in the face of the infection of the proximal component and deficient proximal bony support. This procedure appears to be convenient for the surgeon to correct anteversion of the femoral head and leg length discrepancy.

Transpedicular Screw fixation and Harrington distraction rod are effective means of managing unstable thoracolumbar fracture and fracture dislocation. The authors analysed the 52patients who were treated with above 2methods from March 1986 to February 1993. The results were as follows: 1. Most of patients were in 5th decade compare to younger group and most common cause of injury was fall down, but traffic accident is increasing. 2. The most commonly involved sites were T12and L1 vertebrae and most common type of injury is bursting fracture. 3. Postoperative anterior and posterior column of vertebrae body correction rate were 35.0%/34.4% in ISF group and 29.3%/27.9% in Harrington group. Postoperative correction loss rate were 0.13/0.04 in ISF group and 0.06/0.04 in Harrington group. 4. Postoperative correction of kyphosis angle were average 18 in ISF goup and average 15° in Harrington group. Loss of correction angle was average 23° in ISF group and average 4.4° in Harrington group. 5. Range of spinal fixation was average 3.1 segments in ISF group and average 6.2 segments in Harrington group. 6. There was no significant difference in neurologic recovery between ISF group and Harrington group. The patients who had been recovered neurologically more than 1 grade were 28.6% in Harrington group and 29.2% in ISF group. 7. ISF has some benefit in spnal vertebral body height correction and in maintenance of correction compare to Harrington group. Nevertheless disadvantages of ISF group such as long operative time and possibility of cord compression by pedicular screw, ISF has advantages of almost anatomical reduction and the least spinal fusion.
