Congenital fibrous bands may be found at the gluteus maximus, the gluteus medius,thequadriceqs,the triceps and the deltoideus muscles. Congenital fibrous bands of both gluteus maximus muscles are rare and cause extension contracture of the hip joints. We experienced a case of congenital fibrous bands of both gluteus maximus muscles associated with severe limited flexion of both hips. Almost full flexion of both hips was obtained by excision of the congenital fibrous bands.

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.

Normal ranges of hip motion ia newborns and infants is very important. The newborns and infants, it was very difficult to diffe nciate the limitation of hip motion affected by diseases from the normal ranges of hip motion in newborns and infants whose hips are alwsys flexed, abducted and externally rotated due to intrauterine position. Author measured he normal ranges of hip motion with monthly interval analysis in 400 Busan newborns and infants to note changes of ranges of their hip motion. The result obtained were as follows. 1. The ranges of flexion contracture of hip were varying from 10°–45° (25°±7.93°) in 0–1 month age group to 0°–1 month age group to 0°–20° (9°±4.93°) in 11–12 months age group with average 0–45° (16±7.88°), which menifested gradual decrease in growth. 2. The ranges of abduction were 50°–110° (80°±8.75°), internal rotation, 10°–45° (24±6.46), external rotation, 30°–75°(53°±10.3°) and menifested no changes in growth.

We preset a rare case of traumatic rupture of the iliacus muscle associated with paralysis of the femoral nerve. It occurred in a healthy 17 year old boy immediately after a fall on his back during the Taekwondo practice. The clinical picture is characterized by pain in the groin, a tender mass in the iliac fossa, flexion contracture of the hip, and a complete paralysis of the ipsilateral femoral nerve. This condition rarely occurs in individuals without bleeding tendency

Despite continually improving results of total hip arthroplasty, infection remains the major debilitating complication. The treatments of infected total hip arthroplasty were variable. but initially we removed infected implants and inserted antibiotic containing cemented spacer so called PRSTALAC to prevent scar contracture and disuse osteoporosis. After 6 weeks later, control of infection was clinically and radiologically determined, we inserted new prosthesis with cement. Three weeks postoperatively, patient began touch down standing exercise. We observed infected total hip patient in whom hip had been salvaged successfuily with twostage implantation using so called "" PROSTALAC "" which was made with Moore stem.

PURPOSE: The purpose of this study is to evaluate the results of total hip replacement arthroplasty (THRA) in sequelae of the infected hip with dislocation and severe shortening. MATERIALS AND METHODS: We reviewed 22 cases of THRA performed from January 1985 to March 1995, for painful, dislocated hips secondary to infection in childhood, with shortening of the limb more than 5 cm. Among 22 cases, seventeen were pyogenic infection sequelae, and five were tuberculous infection sequelae. RESULTS: Mean followup period was 44 months (range: 24-111 months) . The mean value of the Harris score was increased to 86.7, which had been 61. The mean postoperative limb-length discrepancy was 1.8 cm and amount of correction ranged from 2.5 cm to 6.1 cm (average : 4.2 cm) . There was remarkable difference between the Crowe Group I and combined Group II and III in correction of shortening. The incidence of radiological loosening was not related to preoperative morbid period or the age of patients. CONCLUSION: The main resistant factor in lengthening of the affected limb was soft tissue contracture related to old age or long term after infection, and complication rate (14%) was higher than that in the other kinds of disease on hip.

PURPOSE: To confirm the effect of the frog leg lateral radiographs for determining the clinical indication of total hip arthroplasty for high riding dislocation and to discuss its theoretical background. MATERIALS AND METHODS: A consequent series of reconstructive THA were studied in 28 recent tuberculous hips. Twenty-three hips (17patients) with developmental dysplastic hip were compared. Preoperatively, frog-leg lateral radiographs were performed in all the patients, which were enhanced using a 2-dimensional computer model to predict the reattachment of the greater trochanter. RESULTS: The modified scores of Merle d'aubigne and Postel improved from a mean of 2.6 points preoperatively to a mean of 5.1 points. Sciatic nerve palsies occurred in three cases. In two cases, they fully recovered, but in one case, it did not. We confirmed that old high dislocation of the hip could be adopted in type 1 and 2 categories of frog leg lateral position. The reconstruction of hip was relatively simple in type 3, however, further study is necessary in type 5 due to unsuitable abduction contracture. CONCLUSION: We confirm that frog leg lateral radiography is effective for determining the operative indication of high riding dislocation. However irreducible frog leg lateral position is absolutely contraindirated for total hip arthroplasty.

The significance of the angle of anteversion of the femur is widely recognised, especially incongenital dislocation of the hip, cerebral palsy, Legg-Calve-Perthes' disease, and in-toeing gait, And many methods of measuring the anteversion have been described since the early work by Drehmann (1909) who determined anteversion by fluoroscopy. But there has been no reliable method of measuring the angle until recently. The authors studied the comparative accuracy and reproducibility by the use of experimental model of femur on computerized tomography, axial technique(Dunn), biplanar method (Ryder-Crane) and fluoroscopic method(Rogers) and reported the results with consideration in clinical utility. 1. The most accurate and reproducible method is computerized tomography, but it has much clinical disadvantages such as uneconomic, limited supply, more time requiring in measuring, and also limited information until the ossification of the femoral head was not occur (below the 18 months of age). 2. The next accurate and reproducible method is fluoroscopic method and it is widely useful except the case of limited motion of hip joint. 3. The Ryder-Crane's biplanar method is very difficult in clincal use because of its poor accuracy and reproducibility, difficult mtasuring technique, limited in the situation of contracture, deformity around the hip. 4. The axial technique of Dunn are also useful in any state of hip joint and simplicity in its technique. 5. The more acceptable clinical slection of measuring the femoral anteversion are the combination of the above two or three methods and comparing it with the opposite hip.

The indication of the total hip prosthesis seems to be far less incidence in this country than western part of the world. Accordingly the report of this surgery is few in Korea. In this report a case of total hip prosthesis operation performed in December 1971 is described. The patient was a 41-year-old female who had marked limited motion of the left hip as well as walking disturbance in such a grade to manage only for toilet by help of bilateral axillary crutches. The hip had 40° of flexion contracture and total range of motion of the hip was 70. Diagnosis was an aseptic necrosis of the femoral head. McKee-Farrar type of total hip prosthetic operation was performed. Walking exercise started from seven weeks after the operation. She has been obtained markedly improved range of motion of the hip with total of 220° actively. 350° passively and normal walking ability. No complication occurred.
