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.

Achilles Tendon ; Rupture

Ligamentous injury of the knee which could be easily occur in sports or traffic accidents resulted in more and severe disability than that of other joints. Rupture of the anterior cruciate ligament which restrain hyperextension, excessive rotation and anterior motion of tibia on femur is the most frequent and significant injury of the knee. Its treatment and clinical significance is one of the most controversial issue and its incidence tends to increase. From 1983 to 1985, modified Scott operation were performed on 10 patients at the department of orthopedic surgery, Chung Ang university hospital. Following results are obtained. 1. No limitation of range of motion of the knee was developed. 2. Intra-articular fixation by use of pull-out wire was done and special consideration was done for the site of fixation on tibia plateau and method of dilatation of posterior capsule. 3. Of the ten patients, nine had negative anterior drawer test, postoperatively.

In the treatment of posterior cruciate ligament injury, posterior displacerrient of tibia might be occured because of the direction of gravity due to weight of lower leg. To prevent this problem several methods have been introduced, but not settled yet. Therfore the author tried to solve this problem by applying Quengel brace that was firstly described by Mommsen in 1922 and perfected by Jordan using the correction of flexion contracture of the knee in hemophiliacs. But owing to the development of some problems in original hinge for prevention of posterior displacement of tibia after posterior cruciate ligament injury, we modified the design of the hinge that more effective anterior traction force should be operated on tibia. The authors applied Quengel brace including original and modified hinge to 21 cases of posterior cruciate ligament injury between June 1983 and May 1986. The followings were obtained. 1. By modification of the hinge, more effective anterior traction force operated on tibia without pressure sore or joint narrowing. 2. On clinical application of modified Quengel brace, posterior displacement of tibia were prevented effectively.

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.

This paper was prepared to determine the effects of degree of initial angulation and the method of treatment toward the end results, and also to report cases of twenty-one children with a radial neck lowed up more than 12 months. The results are as follows: 1. An average follow up period was 34 months, and were ranged from 12 months to 70 months. 2. Displacement patterns of fracture were angulation in 5 cases, partial translocation in 11cases, and total displacement in 5 cases, and translocated fracture was most frequent. According to the degree of angulation, in 10 cases angulation was minor(below 30 degrees), in 8 cases moderate(30–60 degrees), and in 3 cases severe (above 60 degrees). 3. One case was treated by simple cast immobilization, 9 cases were treated by gentle closed reduction, 3 cases were by percutaneus pin reduction with K-wire, 7 cases were by open reduction and K-wires fixation, and 1 case was by closed reduction and incorporating cast immobilization. 4. The results of 20 cases were excellent in range of motion without specific complication. Without considering about the method of treatment, when angulation was severe, more time was required for recovery(Wilcoxon 2-simple test P < 0.02). When the degree of angulation was less than 60 degree, the functional recovery was faster with closed reduction than with open reduction, but with the angulation more 60 degree, there was no significant difference(Spearman correlation coefficient=0.599, P value < 0.05). In conclusion, the severity of initial displacement and the method of treatment were considered to be factors that could affect the recovery time.

Total hip replacement for adults with severe acetabular dysplasia presents a difficult problem because deficient bone stock and soft tissue contractures usually prevent sitting at the normal anatomic level. The rationales of high hip center are due to high failure rate of bulk structural weight bearing graft, good short-term result of hemispherical cementless acetabular component in revision surgery, high hip center but not lateral which does not adversely affect the biomechanics of the hip, and intimate apposition with viable host bone. We represented the short-term results of 21 total hip replacements with proximal placement of the acetabular cup than the anatomical position that is normally used. The mean duration of follow up was 18 months(range, 12-58 months) and the mean age of the patient was fifty-one years(range, thirty to sixty-seven years). Most of these hips had a major deficiency or defect of the acetabular bone stock. They had an aver- age Harris hip score of 47 points preoperatively and 90 points postoperatively. Roentgenographic measurements showed that the mean change in the height of the center of the hip postoperatively was only +6.6 millimeters and the mean change of horizontal location of them was 10 millimeters medial to the preoperative position. Postoperative complications included calcar fracture(1 case), trochanteric bursitis(1 case), postop- erative dislocation(1 case) and one case of radiological loosening of the acetabular component. The center of the hip in THR is not a crucial parameter with regard to the long-term stability of acetabular component, so our recommendation is to place the acetabular component at a more proximal but not lateral position if strong bone stock is available. But future studies of high hip center need to address femoral component longevity.
