The effect of the inverted limbus on closed management of congenital hip dislocation.

A comparative study of 20 congenital dislocations of the hip with inverted limbus treated by closed reduction were compared with a group of 20 controls in which the limbus was non-obstructive as demonstrated by arthrography. In each group 3 hips developed signs of avascular necrosis. Seventeen of the 20 hips with inverted limbus and 11 of the 20 controls required subsequent femoral or acetabular procedures. Half of the hips in both groups at follow-up (mean 9 years) were dysplastic with a CE-angle of less than 20 degrees. Thus, the incidence of avascular necrosis and late clinical and radiographic results were comparable in both groups.

Normal limits of knee angle in white children--genu varum and genu valgum.

Knee angle and intermalleolar (IM) or intercondylar (IC) distance were measured in 196 white children aged 6 months to 11 years to establish normal limits of tibiofemoral angle. Children were maximally bowlegged at age 6 months and progressed toward approximately neutral knee angles (0 degree) by age 18 months. Greatest mean knock knee of 8 degrees was observed at age 4 years, followed by a gradual decrease to a mean of < 6 degrees at 11 years. Normal children aged 2-11 years had knock knee up to 12 degrees and intermalleolar distance up to 8 cm; the existence of bowlegs after age 2 years was abnormal.

The prone hip extension test: a method of measuring hip flexion deformity.

The "prone hip extension test" is described as a simple, convenient, and reliable method of measuring hip flexion contracture. The test may be performed on a padded examining table or bed, it is applicable to the spastic patient, and as the patient is examined prone, it provides a method of flattening the lumbar spine under visual control to avoid obtaining either a falsely high or low value. It, therefore, circumvents the problems commonly associated with the traditional "Thomas Test".

Management of clubfoot deformity in amyoplasia.

Forty-one clubfeet in 22 patients with amyoplasia were studied retrospectively at a mean duration after surgery of 118 months (range, 45-253). The clubfeet were managed by a regimen including initial stretching casts, posteromedial release, and postoperative splinting at night. The mean age at the time of surgery was 7.3 months. Correction of deformity without recurrence was achieved in 11 (27%). Recurrent deformity was corrected by serial casting in eight feet and required secondary operative procedures in 20 feet. In the feet without recurrence of deformity, the duration of splinting at night after surgery was significantly longer than in those with recurrence (p < 0.05). At follow-up, 39 (95%) feet were plantigrade and were considered satisfactory. Our findings suggest that most clubfeet in amyoplasia can be effectively corrected by posteromedial release and that the recurrence of deformity can be reduced by splinting at night and often corrected by serial cast treatment.

Psychosocial development and corrective shoewear use in childhood.

To assess the short- and long-term psychosocial effects of wearing modified shoes during childhood, we compared measures of self-esteem and self-image of 46 adults who wore shoe modifications during childhood with 92 adult controls. The treated cases characterized their remembrance of the experience through a subjective report questionnaire. Those who wore shoe modifications during childhood showed lower self-esteem than controls (p < 0.05). In addition, the treated recalled a decrease in their self-image (41%), the experience as negative (57%), being teased about their footwear (47%), and having their activities limited (41%). These findings show that wearing shoe modifications during childhood, in addition to being ineffective and unnecessary as demonstrated in prior studies, is a negative experience in childhood and is associated with lower self-esteem in adult life. Such data suggest that children who wore modified footwear may fall into the spectrum of the vulnerable child syndrome.
