Seven patients had osteotomy for traumatic varus deformity of the humeral neck following fracture. Indications for the operations were limited active abduction and forward flexion of the arm. The result was good in five cases.
In 11 children, varus deformity of the elbow after supracondylar or transcondylar fractures was corrected with a dome osteotomy. The indication was usually cosmetic. The patients were followed for 5 years. The correction was satisfactory in all the cases, and there was no serious complication.
Eleven children with a persistent varus deformity of 15 degrees or more were operated on with a supracondylar lateral closing-wedge osteotomy. The osteotomy was stabilized with a staple after predrilling for the legs of the staple. No displacement occurred in the osteotomy. The results were excellent in all the cases.
We analyzed various prognostic factors in 112 children operated on for Perthes' disease (Catterall's groups II-IV); special attention was paid to acetabular changes and postoperative containment. The radiographic results of 126 intertrochanteric femoral varus osteotomies were analyzed 2-16 years postoperatively. Catterall's grouping or head-at-risk phenomenon, bicompartmentalization of the acetabulum, and preoperative subluxation of the femoral head did not correlate with the result. The result was worse in cases operated on in the healing phase of the disease and in patients operated on at the age of 9 years or older. The strongest prognostic factor was containment of the femoral head after osteotomy.
10 children with cubitus varus deformity after supracondylar fractures were operated on with a supracondylar lateral closing wedge osteotomy. The medial cortical periosteal hinge was left intact and the osteotomy stabilized with two Kirschner wires and a tension-band wire loop. The osteotomies healed within 2 months, without any complications or recurrence of the deformity. The outcome was satisfactory as regards both cosmesis and mobility.
A 7-yr-old girl presented with progressive shortening of the right upper arm and limitation of shoulder motion. Pseudohypoparathyroidism associated with Albright's hereditary osteodystrophy was diagnosed by biochemical, hormonal and radiographic studies. Her condition was complicated by severe humerus varus on the right side. Proximal humeral valgization osteotomy and concomitant humeral lengthening resulted in an improvement of the shoulder joint motion and activity in daily life.
The long-term functional and radiographic outcome of congenital hip dysplasia in patients previously diagnosed and nonoperatively treated, who subsequently underwent operative treatment after walking age was retrospectively reviewed in 94 patients (87% return). Innominate osteotomy (75 hips, 15.2 years mean follow up) yielded satisfactory late radiographic results in 33% of the subluxated hips and 50% of the dislocated hips, despite more encouraging results at one year (56% and 63.6% respectively). Varus derotational femoral osteotomy (35 hips, 10.8 years mean follow up) yielded a satisfactory radiographic outcome in 55.6% of the subluxated hips and 38.5% of the dislocated hips, with little change from the results at one year. Late diagnosis, late operative treatment, and complications of treatment, particularly ischemic necrosis of the femoral head, were predictive of poor outcome. Combined procedures (10 hips, 12 years mean follow up) or secondary open procedures were ineffective. Although Severin radiographic grade varied with time, functional status remained virtually the same throughout individual follow up. Those patients followed beyond skeletal maturity who developed gross articular incongruity or osteoarthritis, showed a decline in functional status.
Sixty-three patients with cerebral palsy underwent proximal femoral varus derotation osteotomy for 86 subluxing or dislocating hips. Eleven hips underwent concomitant pelvic osteotomy. Adductor tenotomy was performed in all patients. The average preoperative femoral neck shaft angle was 158.2 degrees, with a center edge angle of -2 degrees. Femoral osteotomy effected an average femoral neck shaft angle of 132.2 degrees, with a center edge angle of +8 degrees. A Chiari osteotomy was performed when the acetabular index was greater than 35 degrees. This preoperative acetabular index of 46 degrees improved to 28 degrees postoperatively, and proved to be the most reliable indicator for need of an added pelvic osteotomy.
High tibial valgus osteotomy for varus gonarthrosis was performed in 63 consecutive patients in a homogenous agricultural population using two different surgical techniques. Patients were divided into two groups. A two-level Mittelmeier osteotomy was performed in group A patients, and a lateral closed wedge high tibial osteotomy using the AO/ASIF L-plate was performed in group B patients. Operations were performed by two different groups of surgeons. Patients were evaluated postoperatively for correction of knee axis, functional result, subjective impression, and complications. In group A patients, 80% of the operated knees were corrected to the mechanical axis and in group B patients, 82% of the knees were corrected to 6 degrees-10 degrees valgus of the anatomical axis. Ninety percent, 70%, and 54% of group A and 91%, 73%, and 57% of group B patients were rated as satisfactory results at 5, 9, and 12 years postoperatively, respectively; these differences were not statistically significant. One year postoperatively, 91% of group A and 96% of group B patients reported their symptoms had improved. However, patient satisfaction decreased at 5, 7, and 12 years postoperatively, with 91%, 89%, and 66% of group A and 96%, 93%, and 68%, respectively, of group B patients reporting their symptoms had improved; these differences were not statistically significant. Postoperatively, most patients returned to full agricultural activity. Total knee arthroplasty, which was later required in 12% of the knees, was not significantly jeopardized by the previous osteotomy.
OBJECTIVE: To determine the minimum incidence (MI) of congenital talipes equino-varus (CTEV) in children; evaluate the association between CTEV and other congenital anomalies, and to assess the presence of residual deformities after conservative management at the physiotherapy department of Harare Central Hospital (HCH), Zimbabwe. DESIGN: A three year retrospective study. SETTING: Physiotherapy Department, HCH, Harare, Zimbabwe. SUBJECTS: Eighty-two children with CTEV who were assessed and treated at HCH Physiotherapy Department from January 1994 to December 1996. MAIN OUTCOME MEASURE: MI of club foot and degree of correction of the club foot after conservative management of the deformity by the physiotherapist. RESULTS: An MI rate of about 0.9 per 1000 was found over a three year period. It was also found that 30.5% of these children had other associated congenital abnormalities. There was no significant association between gender and severity of deformity (P = 0.326). A significant association between the severity of CTEV and the presence of other associated congenital deformities was found (P = 0.013). 91% of the feet were found to have a satisfactory result of treatment using the Wynne Davis scoring system (WDSS). 52% of the patients with residual deformity after discharge from physiotherapy presented with limitation in ankle and sub-talar movements. This study also indicated that children with grade 2 type of deformities were more likely to have other congenital abnormalities than those with grades 1 or 3. CONCLUSION: The MI of CTEV in the studied population was found to be lower than other countries. The WDSS indicated that a great majority of the feet examined scored above average score.
A female with spondyloepiphyseal dysplasia (SED) tarda suffered bilateral hip pain since about the age of ten. Her radiographs revealed subluxation and irregularity of the hip joints with acetabular dysplasia. Transtrochanteric varus osteotomy was performed on her left femur at 13 years of age and on her right femur at 14 years of age. The congruities of both hips improved after surgery. At follow-up, she had no pain in either hip even after walking for an extended period. Improved activity in daily life was noted.
A cubitus varus deformity, secondary to a supracondylar fracture, was treated with a short oblique osteotomy and the Ilizarov external fixator. An excellent anatomic and functional outcome resulted. This method may prove to be of significant value in the treatment of this difficult deformity.
The aim of this paper was to evaluate the acetabular roof remodelling process and changes of the Wiberg angle after proximal femur varus drotational osteotomy up to skeletal maturity. The analysis included 33 patients after 48 osteotomies (in 15 patients on both sides). The age at the time of surgery ranged from 1.0 to 9.8 years, mean 4.7 years. Follow-up time ranged from 7.6 to 15.9 years, mean 12.0 years. Statistical analysis showed significant differences in acetabular index, Sharp's angle, acetabular ratio and Wiberg's angle between early post-operative x-rays and radiograms taken at the last follow-up. Comparison not only of the remodelling dynamics, but also final radiological measurements confirm the necessity for surgical of severely dysplastic acetabular roof, especially in older age groups.
The purpose of this study was to assess the efficacy of early physical therapy in a series of 189 cases of congenital talipes equino-varus (CTEV) or clubfoot. Physical therapy alone led to full functional recovery with no complications in 67 cases (35%). The outcome of treatment was directly correlated with the severity of the deformity, early therapy, and regular attendance at treatment sessions. Even when full recovery was not achieved, physical therapy led to a significant reduction of rigidity and greatly facilitated surgical treatment. These findings indicate that it is always valid to recommend physical therapy prior to attempting surgical.
Evaluation of radiographs of 267 children with 465 intertrochanteric rotating varus osteotomies, carried out between the ages of 15 months and 14 1/2 years. The period of follow-up varied between 2 and 15 1/4 years. 1. The CCD angle on the last radiograph was normal in 77%, once more in values in 16.2%, coxa vara in 7%. 2. The AT angle was about normal only in 58.3% (0-20 degrees); it relapsed in 8.4% (over 35 degrees); in 8.8% a corrected angle did not return after retrorotation, particularly on the left. 3. The Ac angle was normal in 63.3%. 4. The CE angle corresponded to the norm in 59.1%. 5. Good late results (normal angles and shape of head) occur only in 20%. If one omits the AT condition, they rise to 40%. 6. The main causes of return of valgus appear to be: too early operation before the fifth year, mainly when disregarding the dysplastic acetabular roof, insufficient correction of the CCD angle of over 115 degrees, and technical faults. For physiologic weightbearing by the acetabular roof an AT angle of 10 appears necessary. 7. When dysplasia of the acetabular roof is present, the polyaxial correction of the proximal end of femur must be combined with acetabuloplasty or pelvic osteotomy.
The choice of first-line treatment for congenital varus equine clubfoot remains a controversial issue largely dependent on experience. In France, functional treatment predominates. In 1948, Ponseti proposed reducing the deformity with successive casts. Although cast treatment is a very old method, Ponseti's method is original because it is based on strict rules established from anatomic evidence. The goal is not to correct the apparent deformation, but on the contrary to impose a simultaneous supination and abduction of the foot. Once the calcaneopedal block has been derotated, percutaneous tenotomy of the Achilles tendon is performed. We relate our experience with this method and recall the precise technique used to make the casts. After the cast, derotation braces are worn at night but rehabilitation exercises are not required. We emphasize the quality of the clinical reduction achieved as well as the smaller number of patients who require surgery at walking age.
Twenty-six comminuted distal femur fractures treated with a lateral condylar buttress plate were followed up until fracture union or implant revision (mean follow-up, 26 months). Mean postoperative angle (medial distal femoral angle immediately after surgery) was 96 degrees, and mean final angle (angle at fracture healing or implant revision) was 91 degrees (P = .06). Distal femoral angle decreased 5 degrees or less in 15 patients, 6 degrees to 10 degrees in 8 patients, and more than 10 degrees in 3 patients. Final distal femoral angle was 90 degrees or less in 13 of the 26 fractures: 38% of these 13 fractures required reconstruction for nonunion, malunion, or knee arthrosis. The lateral condylar buttress plate, which is not a fixed-angle device, allowed more than 5 degrees of varus collapse to occur in 42% of the comminuted distal femur fractures.
This prospective study examined the kinematic and temporal/spatial effects of proximal femoral varus rotation osteotomy (VRO) on the gait of individuals with cerebral palsy from preoperative to 1-year postoperative status. Participants were a consecutive sample of 37 individuals (14 males, 23 females). The analysis consisted of three-dimensional kinematics, temporal/spatial measures, and functional status. A curve representing the difference between the preoperative and 12-month postoperative conditions was calculated for each joint motion. Ninety-five percent confidence intervals were calculated about the mean difference curves using a bootstrapping technique. VRO resulted in improved cosmesis and objective improvement in gait, including a statistically significant increase in hip external rotation and hip extension, a decrease in anterior pelvic tilt, and an increase in knee extension strength. The use of confidence bands to identify surgical outcomes with respect to kinematic variables has enormous value for patients and professionals. Long-term follow-up is needed to see if the aforementioned gains improve.
