Traumatic hip joint dislocations account for 2-5% of total joint dislocations. Bilateral asymmetric hip joint dislocation with anteriorly and posteriorly dislocation is an even more rare case because it was according to G. Loupasis reported in 11 cases only since 1879. We want to report 2 cases of bilateral asymmetric hip joint dislocation with unilateral acatabulum fracture which happened in our hospital. Bilateral asymmetric dislocation of hip joint accompanied by unilateral fracture of acetabulum is a very rare case so statistical verification cannot be done. However, close examinations are required at early treatment and follow-up because the patterns of dislocation and fracture of hip joint are variable and an orthopedic emergent condition and several complications may occur at both hip joints.

The purpose of this study are to determine the proper radiographic measurements for hip deformity in spastic cerebral palsy patients, and the correlation of hip deformity with neurological involvement, ability of ambulation. Thirty children with cerebral palsy(22 males, 8 females) were evaluated by measurement of the migration index, acetabular index, center edge angle from bilateral hip APs(anterior posterior view). The result are as follows; 1. The incidence of hip dislocation, among the thirty children fifteen children were found to be dislocated, and more significantly high in non-walking group than in walking group(p<0.05) and in quadriplegia than in diplegia(p<0.05). 2. When compared to normal hip and dislocation hip, the migration index was significantly higher(p<0.01) and the center edge angle was lower in the dislocation hip than in the normal hip. 3. Correlation of radiological findings in right and left hip, the migration index and the center edge angle were highly correlated(p<0.01). We recommand regular intervals X-ray study for early diagnosis and management of hip dislocation in spastic cerebral palsy.

A 6-year-old, 36.5 kg castrated male Golden Retriever presented for revision surgery for left total hip replacement. The patient underwent removal of the cup and head implants due to unmanageable prosthetic hip dislocation, despite revision surgery. On physical examination, the dog showed persistent weight-bearing lameness after exercise of the left hindlimb with mild muscle atrophy. Radiographic examination revealed dorsolateral displacement of the femur with a remnant stem and bony proliferation around the cranial and caudal acetabulum rims. The surgical plan was to apply the dual mobility cup to increase the range of motion and jump distance to correct soft tissue elongation and laxity caused by a prolonged period of craniodorsal dislocation of the femur. The preparation of the acetabulum for cup fixation was performed with a 29-mm reamer, and the 29.5-mm outer shell was fixed with five 2.4-mm cortical screws. The head and medium neck of the dual-mobility system were placed on the cup, and the hip joint was reduced between the neck and stem. The dog exhibited slight weight bearing on a controlled leash walk the day after surgery. The patient was discharged 2 weeks postoperatively without any complications. Six months postoperatively, osseointegration and a well-positioned cup implant were observed, and the dog showed excellent limb function without hip dislocation until 18 months of phone call follow-up.

Total Hip Replacement in a patient with chronic coxofemoral joint dislocation is a challenging problem because chronic coxofemoral joint dislocation causes severe morphological changes. These challenging factors make surgery more difficult and increase the possibility of postoperative complications including cup implant dislocation and prosthetic joint luxation. All patients were diagnosed having at least 2 months of coxofemoral joint dislocation. On physical examination, crepitus was noted in the coxofemoral joint. Radiographs revealed hip joint dislocation with mild to severe degenerative changes. Total hip replacement was planned for all patients. Dorsal acetabular rim deficiency in 3 cases was augmented using a locking plate and polymethylmethacrylate bone cement. All cases have shown difficulty in prosthetic joint reduction. Pectineus and rectus femoris muscle origin were released in all cases. At 12 months follow up, all patients showed satisfactory ambulation. The issues on perioperative prosthetic joint reduction and luxation due to chronic coxofemoral joint luxation with muscle contracture and dorsal acetabular rim deficiency can be resolved by muscle releasing and dorsal acetabular rim augmentation.

Traumatic fracture-dislocations of the hip frequently result from high-energy injury, and hip dislocations are commonly associated with severe concomitant injuries. Sciatic nerve injury often accompanies traumatic fracture-dislocation of the hip, but neurologic examination at the time of injury is difficult in severely traumatized patients with decreased consciousness. We present such a case of multiple traumas with traumatic hip dislocation and sciatic nerve injury after reduction, and we found that magnetic resonance image (MRI) played an important role in developing a management plan.

Urgent reduction is required in cases of traumatic hip dislocation to reduce the risk of avascular necrosis of the femoral head. However, in cases of femoral head fractures, the dislocated hip cannot be reduced easily, and in some cases, it can even be irreducible. This irreducibility may provoke further incidental iatrogenic fractures of the femoral neck. In an irreducible hip dislocation, without further attempting for closed reduction, an immediate open reduction is recommended. This can prevent iatrogenic femoral neck fracture or avascular necrosis of the femoral head, and save the natural hip joint.

이 연구에서 저자들은 다음과 같은 결론을 얻었다. 1. 고관절 조영술은 수술전에 미리 유용한 정보를 줌으로써 수술전 계획을 세우고 수술을 체계적으로할 수 있을것으로 사료된다. 따라서 고관절 조영술은 도수정복 혹은 수술적 정복전에 필수적으로 시행하여야 할 것으로 사료된다. 2. 고관절 조영술은 비구 관절순, 원형인대의 평가에 매우 유용하였으며, 횡비구인대에 대한 정보는 제한적이었다. 3. 고관절 조영술은 단순 방사선 촬영에 비하여 중앙연각의 평가에 훨씬 유용하고 실제 병리적 소견에 합당한 정보를 주었다.

The hip is a stable ball-and-socket joint. Bilateral anterior dislocations of the native hip joints account for fewer than 1% of all dislocations. We present a unique case of a bilateral anterior dislocation in a patient who presented to our institution within 6 hours of trauma. The dislocations were promptly reduced under propofol anesthesia in the operating room. The patient did not suffer a concurrent fracture. After the procedure, we performed regular X-ray examinations for 2 years to rule out the development of avascular necrosis of the head of the femur. The course of the patient was unremarkable.

This study aims to provide basic size data for the development of a hip dislocation prevention garment for cerebral palsy (CP) children and useful information for the design of garment products for CP children through identifying differences in body shape between CP and non-CP children and reviewing the tibial-stature prediction formulas of previous studies. Forty-seven Korean children with CP aged 2 to 14 years were measured for body size from October 2019 to August 2020. Body measurements of 18 sites, including greater trochanter length, which is an important site for a hip dislocation prevention garment, were collected and analyzed. Data of non-CP children were taken from same age of Size Korea and compared. Tibial-stature prediction formulas suggested in four previous studies were also reviewed. CP children had significantly lower stature as well as circumferential dimensions when compared to non-CP children. Greater trochanter length is difficult to predict through other body dimensions. Thus, direct measurement is required. Of the general key dimensions used in the clothing industry, only hip circumference could explain the body shape of CP children. Tibial-stature prediction formulas cannot always but tend to largely predict the actual stature of CP children.

Developmental dysplasia or dislocation of the hip is the most pronounced form of a condition in which the femoral heads tends progressively to leave the acetabulum. In the young child the variability of findings and course suggest a spectrum of conditions in which there are a number of common features: restriction of movement, particularly of abduction in flexion; shortening; and abnormal radiology, including a sloping or dysplastic acetabulum and delay in the appearance of the upper femoral epiphysis. It is vital to make the diagnosis of a congenital dislocation as soon after birth as possible. Conservative treatment with an abduction brace before the child run begins to walk is completely adequate, but after the age of 4 even surgical repositioning is difficult and after the age of 7 it is almost impossible. The aim of the study was to gain insight into the value of physical therapy of developmental dysplasia or dislocation after operation.
