The tibial plateau fracture which involving articular surface of the proximsl tibia is very common in pedestrian injury of the traffic accident and sometimes results in significant disability in knee joint function. The authors analized 40 cases of the tibial plateau fracture treated in our depsrtment during the year 1980 through 1985. The results obtained are as follows : l. 15 cases were treated by conservative methods. 2. 25 cases were treted by operative methods. 3. 33 cases(82.5%) were “Acceptable” group according to Roberts criteria.

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

Two cases of traumatic bilateral anterior and posterior dislocation of hip are reported. Dislocations were developed by a traffic accident as a passenger injury in truck. In both cases, the fractued femoral heads appeared posteriorly dislocated on x-ray examination and one of them was removed through posterior approach. Primary arthroplasty for operated hip was not attempted because the patient was young and the defect seemed to be unrelated to weight bearing surface. Extreme rarity of its incidence and curious uncertain mechanism of injury urge to report these cases.

It would be naive to assume that any operative procedure is the solution to the problem of sacral pressure sore in the field of the orthopaedic surgery. The procedures outlined here involve the creation of compound myocutaneous flaps of the gluteus maximus muscle, skin, and the subcutaneous tissue. The myocutaneous flap us- ing the gluteus maximus muscle is a vascular flap instead of a random flap, with better blood supply for healing and advantage of an increased amount of cushion effect. We present an alternative method which will provide satisfactory and substantial soft tissue coverage in sscral pressure sores.

Rhabdomyosarcoma which was first described by Weber has generally been considered asan uncommon tumor. Pack and Eberhart were of the opinion that rhabdomyosarcoma represented 13.9 percent of soft tissue sarcomata. Recently it was classified as four types such as pleomorphic, embryonal, botryoid and alveolar type by many authors. We have experienced two cases of embryonal rhabdomyosarcoma, one arised within left leg and the other within right foot. The former(3 months old, female) showed tumor mass at birth, the latter(13 months old, male) showed at 1 month after birth.
