Contracture of the Hip Secondary to Fibrosis of the Gluteus Maximus Muscle / 대한정형외과학회잡지

Four patients were treated who had limited flexion of the hips and various degrees of contracture of the abduction and external rotator muscles because of fibrosis of the gluteus maximus muscle. Each patient had a typical restriction of motion such that an affected hip could not be flexed in the usual sagittal plane, but had to be flexed in abduction. Genetic, congenital and postnatal factors have been suggested as the cause of fibrosis of gluteus maximus muscle. Three of the 4 patients reported here are of congenital origin and another one is of postnatal factor repeated intramuscular injections. Excellent correction of the hip contracture was achieved in all patients by division of the fibrotic bands.

Serial Bone Scans According to Fracture Healing in Tibia / 대한정형외과학회잡지

Total 40 cases of serial bone scans with Tc99-m-MDP performed on less than 24 hour, 2nd day, 3rd day, 5th day, 1 week, 4 week, 12 week and 1 year respectively after fractures in tibia were analysed. All 5 cases of bone scans performed within 24 hour after injury showed increase in generalized tracer uptake and 3 cases of them(60%) showed localized increase in tracer uptake at the fracture sites. The earliest bone sean performed 9 hour after injury showed generally and locally increased uptake at the fracture sites. All 5 cases of bone scan performed 1 year after injury sinowed localized increased uptake at the fracture sites and 2 cases of them (40%) showed generalized increase in tracer uptake. Bone scans performed 12 week after injury showed the most outstanding increase in generalized and localized tracer uptake. Bone scans performed 1 year after injury showed decreased amount of generalized increase in tracer uptake (but more increased uptake than normal) but the localized increase in traccer uptake at the fracture sites was observed persistently. More study should be needed to clarify the corelationship between the presence of cold spots during the fracture healing and the union of the fractures. It is difficult to differentiate the old fractures to fresh fractures with the bone scans performed within 1 year because of persistent increase in tracer uptake to 1 year after fracture.

Effect of Buttress Graft in Anterior Fusion for Spinal Tuberculosis / 대한정형외과학회잡지

Long term follow-up study was done on 38 cases of anterior fusion for spinal tuberculosis especially about effect of buttress graft. The average follow-up period was 16 months. 14 cases of effective buttress group were appeared' to achieve more rapid bony union and prevent further kyphosis or lateral wedging of the involved vertebral body than inadequate buttress group of 7 cases.
