Coxa Vara* ; Follow-Up Studies*

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.

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.

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.

The femoral neck fracture in children are extremely rare and occur secondary to severe trauma. Many authors recommend early anatomical reduction and firm internal fixation because of many complications after treatment. Eleven displaced femoral neck fractures in children who were treated at the Keimyung University Dong San Medical Center from February, 1989 to February, 1993. Following results were obtained, after clinical and radiological evaluations. 1. Fractures of the femoral neck in children occurred from five to sixteen years, the highest inci dence was between ten and thirteen years of age. 2. The main causes of the fracture were traffic accident in 9 cases. 3. 10 cases were treated by arthrotomy, open reduction and internal fixation and one by closed reduction and internal fixation. 4. Operation were performed within 24 hrs after trauma in 5 cases, within 5 days in 4 cases, and 2 cases were performed within 10 days after trauma. 5. According to the classification of Delbet and Colonna(12), cervicotrochanteric fracture(type III) was the most common type(7 cases). 6. The degrees of displacement were 4 cases totally displaced, one case more than two third dis placed, 4 cases 1/3 to 2/3 displaced, and 2 cases less than one third displaced. 7. Complications were transient AVN confirmed by bone scan(1 case) and coxa vara due to nonunion(1 case). 8. According to the Ratliffs assessment(22) the results were good in 9 cases, fair in one, and poor in one.

Deveolopmental coax vara represents coax vara not present at birth but rather developing in early childhood, showing a progressive deterioration in the proximal femoral neck-shaft angle during growth. In order to determine the factors that could affect the results of corrective osteotomy, we evaluated the results of 15 developmental coax vara in 12 patients who had been treated with the femoral osteotomy at the Department of Pediatric Orthopedic Surgery, Seoul National University Children's Hospital, from February 1983 to March 1993. Of the 12 patients, there were 6 boys and 6 girls. Three patients had bilateral operations, 5 patients on the right, and the remaining 4 patients on the left. Average at the onset of symptoms was 4 years plus 5 months(range; from 1 year to 7 years plus 2 months), and average age at the tome of operation was 6 years plus 3 months(range; from 2 years plus 4 months to 10 years). We could obtain the following results: 1. Average post-operative loss of neck-shaft angle was 5% in the cases in which post-operative neck-shaft angle was converted more than 130 degrees, and was 8% in the cases in which post-operative neck-shaft angle was converted less than 130 degrees. 2. Loss of neck-shaft angle was higher during the first post-operative period, and was higher in cases in which the triangular osseous defect was persistent post-operatively. There was no correlation between the post-operative neck-shaft angle and disappearance of triangular osseous defect. 3. The femoral anteversion was converted 8.7 degrees to 27.2 postoperatively. 4. The premature arrest of the capital femoral physis was higher in cases in which the neck-shaft angle was less than 130 degrees postoperatively. 5. Leg length discrepancy, which was 2.1 cm preoperatively, did not change in cases in which the neck-shaft angle was more than 130 degrees postoperatively. However, it was converted to 3.3 cm in cases in which the neck-shaft angle was less than 130 postoperatively. 6. we could observe the femoral head deformity in 6 out of 7 cases in which the operation was performed after 7 years of age. We could draw the following conclusion based on our results: 1. We must correct the neck-shaft angle more than 130 degrees. 2. We could not equalize the leg length discrepancy by corrective osteotomy alone. 3. It may be reasonable to perform the corrective osteotomy before 7 years of age.
