Another compression screw then is placed discount motrin 400 mg pain treatment methods, followed by a neutralization screw (Figure S3 purchase 400 mg motrin free shipping treatment of acute pain guidelines. Fol- lowing the reduction, the medial cortex of the femur should be in complete contact and under compression, often with a little opening of the lateral aspect of the osteotomy (Figure S3. The vastus lateralis is closed over the lateral aspect of the plate to provide some soft-tissue coverage. Closure of the fascia latae pro- vides additional coverage of the plate, which then is followed by closure of the subcutaneous tissue and skin closure. Postoperative Care Except for rare cases of extreme osteoporosis, no external cast immobiliza- tion is required. Anterior/posterior and frog lateral pelvis radiographs with good positioning should be made in the operating room before the child awakens from the anesthesia (Figures S3. These radio- graphs provide a good baseline should there be later concerns about the po- sition of the osteotomy or the hardware. Physical therapy is initiated on the first or second postoperative day with passive range of motion and mobi- lizing the child out of bed to the wheelchair. Activity is advanced with full weight bearing, usually with the goal of assisted ambulation before discharge from the hospital on day 4 to 7 after surgery. The first radiograph is obtained 4 weeks after surgery and should show some callus formation. Most chil- dren have very minor pain by this time and are making progress toward bet- ter ambulation. Independent ambulation to the child’s preoperative level is not expected until 3 months after surgery. Improvement in the child’s gait pattern should be expected up to 1 whole year after surgery. Peri-ilial Pelvic Osteotomy Indication The peri-ilial pelvic osteotomy almost always is performed in conjunction with a femoral varus and shortening osteotomy. It is indicated to correct the posterior superior acetabular dysplasia caused by the most common spastic hip disease. An incision is made in the bikini line approximately 1 cm medial to the anterior superior iliac spine and extended laterally for approxi- mately 4 cm (Figure S3. The incision is carried down to the sub- cutaneous tissue until the fascia is identified. The subcutaneous tissue then is elevated off the fascia until the iliac crest is identified (Figure S3. A sharp incision is made in the iliac crest halfway between the me- dial and lateral sides, directly through the apophysis of the iliac crest from as far posterior lateral to the anterior superior iliac spine. Subperiosteal dissection of the lateral wall of the ilium then is per- formed, using care to bring the whole iliac apophysis off starting pos- teriorly. This dissection is packed with a 4 × 4 sponge (Figure S3. Subcutaneous dissection is performed distal to the anterior superior iliac spine in the anterior medial aspect of the wound. The interval between the sartorius and fascia latae is opened, being careful to preserve the lateral femoral cutaneous nerve. The interval between the sartorius and fascia latae is opened down to the ante- rior inferior iliac spine at the insertion of the direct head of the rectus femoris. Retractors are placed to hold this interval open, and the iliac crest between the anterior inferior iliac spine to the anterior superior spine is palpated. Using a sharp scalpel, the anterior inferior iliac spine is incised along the anterior ridge to the anterior superior spine. Subperiosteal dissection of the lateral aspect of the ilium then is per- formed. This dissection allows subperiosteal exposure right down to the origin of the hip joint capsule (Figure S3. At the area where the origin of hip joint capsule is identified, sub- periosteal dissection is extended posteriorly and inferiorly to the level of the triradiate cartilage. Fluoroscopic control then is utilized, and a straight 1-cm wide osteo- tomy is inserted midway between the medial and posterior aspect of the acetabulum, making sure to keep the osteotomy in direct lateral profile (Figure S3.

In these individuals quality motrin 600mg pain medication for dogs after neuter, the best method for measuring anteversion is the CT scan because low to normal neck shaft angle is usually present as these children already had the coxa valga corrected cheap motrin 400mg free shipping pocono pain treatment center. The irregular surfaces of the femur can be more easily dealt with by having a whole outline of the proximal femur, which is provided by the CT scan. In the operating room, using the fluoroscope to understand coxa valga and femoral anteversion is routine as part of the operative procedure. However, it is not necessary to make an absolute measurement of the degree of femoral anteversion pre- operatively in all children who have severe internal rotation and are being brought to the operating room to have this corrected. If children have not previously had hip surgery, and are being scheduled for surgical correction of the internal rotation deformity of the femur, increased femoral antever- sion is the problem and measurement of the anteversion beyond the physi- cal examination is not routinely needed. The Etiology of Femoral Anteversion and Coxa Valga Femoral anteversion is a normal position of the femur in infants. Femoral anteversion varies from 40° to 60° at birth, and then slowly resolves with growth until the normal 10° to 20° of anteversion is reached by age 8 years. There is a significant variation in the magnitude of anteversion at birth. In children with spasticity, the normal resolution of this anteversion does not occur because the spasticity and poor motor control do not provide a me- chanical environment in which the femur derotates itself. In addition, chil- dren with spasticity who maintain this high degree of infantile anteversion often have decreased motor control, which means they have less ability to compensate for this tendency to internally rotate from the increased femoral anteversion. A second aspect that may magnify the persistent infantile femoral anteversion begins to show up in middle childhood with the develop- ment of internal rotation contractures, which further magnify the persistent 10. His parents were concerned about the severe internal rotation position of the left hip. A hip re- construction was performed, which gave him excellent position (Figure C10. Following this reconstruction, he did well for 5 years; however, his parents noted the slow returning of the internally rotated posture. They were concerned that he was again developing a dislocated hip; however, the radiographs were normal (Figure C10. On physical examination he was noted to have adduction of the left hip limited to 10°, full flexion, and extension; however, the left hip external rotation was only to −20°. A CT scan showed a posterior displacement of the femoral head with almost posterior subluxation and 30° of ante- version (Figure C10. A soft- tissue release, including adductor lengthening, a gluteus medius and minimus release, and release of the anterior tensor fascia lata allowed the hip to externally rotate, and the femoral head reduced nicely into the joint by 1 year later (Figure C10. These contractures often become quite problematic in adolescence. A third cause of this internal rotation may be related to poor motor control and poor balance. Some children seem to gain stability from internal rotation of their legs, thus providing better balance in their walking gait. Some of these children have their femoral anteversion corrected, and then over several years as they gain better walking speed, will tend to return to the posture of internal rotation at the hips. However, on imaging, the femoral anteversion has not returned, but the internal rotation contractures have slowly returned. Muscle Contractures Spastic and contracted internal rotator muscles definitely contribute to the internal rotation posture that many children with CP have at their hips. Based on modeling work, there is a great variability in the lever arm and abil- ity of individual muscles to cause internal rotation of the hip. The muscles that produce in- ternal and external rotation are a complex combination also determined by the position of the hip joint. As an example, the iliopsoas can be either an internal or external rotator, depending on the position of the hip joint. The adductor longus, brevis, gluteus minimus, and medius are the primary internal rotators of the hip joint.
