PURPOSE: Single or multiple fibrous dysplasia of the proximal femur can cause coxa vara, Shepherd's crook deformity and a leg length discrepancy for those patients who require surgical treatment. We wanted to evaluate the efficiency of surgical treating fibrous dysplasia of the proximal femur. MATERIALS AND METHODS: Among the patients who underwent surgical treatment at our hospital during the period of June, 2001 to October, 2007, we selected 18 patients who underwent curettage and bone graft or valgus osteotomy and internal fixation due to proximal femur involvement. The clinical results were analyzed based on the patients' clinical records and radiologic findings. RESULTS: The group of patients with a normal neck-shaft angle (Group 1) could achieve satisfactory results by undergoing curettage, bone graft and internal fixation. The other group of patients who progressed to Shepherd's crook deformity (Group 2) could have satisfactory results when they underwent valgus osteotomy and soft tissue release or both proximal femur shortening osteotomy and valgus osteotomy, but not with undergoing valgus osteotomy only. CONCLUSION: Varus deformity in patients with fibrous dysplasia may progress even though they undergo valgus osteotomy. It is important to consider the preoperative biomechanical condition of the proximal femur before performing surgery.

Developmental coxa vara is a rare disease and the symptoms do not appear at birth, but rather, they appear at the age of walking. Clinically, the symptoms include a waddling gait, limb length discrepancy and frequent weariness. Developmental coxa vara is sometimes associated with skeletal dysplasia. Especially, it is associated with spondylometaphyseal dysplsia and the vertebral bodies and long bones are affected. The authors report here on diagnosing and treating this rare disease and we review the relevant literatures.

Congenital coxa vara is a rare congenital deformity seen in infancy and childhood and usually not discovered until walking is begun and characterized by a progressive decrease in the angle between the femoral neck and shaft and consequently by a progressive shortening of the limb and also by the presence of a defect in the medial part of the neck We have experienced a case of it treated with valgns osteotomy and the case review is presented.

In 5 cases of congenital coxa vara, 7 cases of acquired coxa vara and 4 hips in 3 cases of acquired coxa valga, we performed subtrochanteric osteotomies at Department of Orthopedic Surgery, SeoulNational University Hospital, from December 1980 to February 1984. At a relatively short interim follow-up, following observations were made on the correction of the femoral neck-shaft angle deformities. l. In the congenital coxa vara group, at an average follow-up of 1 year and 3 months, 97.9% of the correction obtained by osteotomy was maintained, based on the roentgenographic measurements of femoral neck-shaft angle. In the acquired coxa vara group, at an average follow-up of 1 year and 2 months, 93.3 % of the correction obtained by osteotomy was maintained. In the acquired coxa valga group, at an average follow-up of 1 year and 5 months, 92.9% of the correction obtained by osteotomy was maintained. 2. At final follow-up, leg length gain averaged 1.26cm in the congenital coxa vara group and 2.23cm in the acquired coxa vara group. An average 0.70cm decrease in leg length was noted in the acquired coxa valga group. 3. Trendelenburg sign, which was positive in all the cases of the congenital and acquired coxa vara group, reverted to negative in all. 4. Slight overcorrection in cases of the acquired coxa vara and undercorrection in cases of the acquired coxa valga, is recommended for later loss of surgically corrected femoral neck-shaft angle. In the congenital coxa vara, it appeared that loss of correction was relatively minor.

PURPOSE: To investigate the results of treatment of reverse oblique trochanteric fractures with compression hip screw. METHODS: We reviewed the results of 12 cases of reverse oblique trochanteric fracture treated with compression hip screw from January 2000 to December 2006 which could be followed up for more than 1 year. The mean follow up period was 26 months (15~40). The mean age was 48 years old. Injury mechanism was composed of 6 cases of traffic accident and 6 cases of fall down. 8 persons were man. We investigated the union time, degree of neck-shaft angle change, amount of sliding of compression hip screw, complications, functional and clinical results. RESULTS: 10 cases were united and the mean union time were 5 months (3~8). The mean neck-shaft angle change was 3.5 degrees (0~12). The amount of sliding of compression hip screw was 8.9 mm (2~24). There were six coxa vara, six leg due to coxa vara shortening, two nonunion, and one superficial infection. Unsatisfactory results of Jensen's social function score and Parker and Palmer's mobility score were studied. CONCLUSION: The results of treatment of reverse oblique trochanteric fractures with compression hip screw were relatively unsatisfied.

Spondyloepiphyseal dysplasia congenita (SEDC) is a kind of skeletal dysplasia, inheritable condition. The clinical features of SEDC are dwarfism, myopia with or without retinal detachment, coxa vara, thoracic dysplasia with respiratory failure and laryngotracheal stenosis. A point of particular concern to anesthetists is odontoid hypoplasia which, combined with ligamentous laxity, leads to atlantoaxial instability. We report successful general anesthesia for cervical spine fusion of a patient with SEDC.

PURPOSE: To analyze complications and their effects on prognoses of children hip fractures. MATERIALS AND METHODS: 26 childhood hip fractures (6 type I, 7 type II, 10 type III, 3 type IV) were studied for 11 years (1986-1997) . We analyzed factors possibly related to complications and their effects on prognoses, especially avascular necrosis (AVN) of the femoral head. RESULTS: Of 26 patients, there were 7 AVN (27%) , 2 nonunions (8%) , 3 coxa vara (12%) , 9 premature epiphyseal closures (35%) , and 2 infections (8%) . Of 7 patients with AVN, 3 patients had type I fracture and 4 patients had type II fracture. No AVN developed in type III and IV fractures. Of 2 patients who had type I fracture with dislocation, all patients had AVN (100%) . Four of 14 patients who had displacement of the fracture site and one in 10 patients who had non-displacement fracture developed AVN. In our study of the incidence of AVN according to surgical reduction time after injury, 3 (60%) of 5 patients who were treated by surgical reduction within 6 hours and 4 (19%) out of 21 patients who were treated by surgical reduction after 6 hours developed AVN. CONCLUSION: In childhood hip fracture, surgical reduction time after trauma (<6 hours) did not seem to be a critical factor in preventing AVN. Force of injury and level of fracture site which jeopardize the blood supply to the femoral head were important factors. Age at time of injury was also important. Containment treatment of younger children (<10 years) and surgical treatment of older children (>10 years) were found to be an effective treatment of AVN. AVN concomitant with pyogenic infection had the worst prognosis.

PURPOSE: To determine the developmental patterns of 4 major deformities of femoral head commonly observed in Legg-Calve-Perthes disease (LCPD): coxa plana, coxa magna, coxa vara, subluxation. MATERIALS AND METHODS: We reviewed the clinical records and radiographs of 85 unilateral LCPD children who were followed up from the early stage of disease to full skeletal maturity. Four major deformities were measured and observed during 3 periods: the active disease stages of avascular necrosis and fragmentation, the healing stage, and skeletal maturity. RESULTS: All four deformities were first observed at early stages of the disease, avascular or fragmentation stage. Appearance rates were 79% in coxa plana, 28% in coxa magna, 35% in coxa vara, and 27% in subluxation. The gradual progression of deformities with time which was demonstrated at the healing stage and at skeletal maturity were observed in all except subluxation. And this gradual increase was supposed to be dependent on the normal bony growth with aging. CONCLUSION: We determined the developmental pattern of major deformities of the femoral head. And this determination will help to understand the natural course of deformity which is clinically important in terms of late osteoarthritis.
