[Congenital superior radioulnar synostoses. A study of 43 cases]
Insights
Superior radioulnar synostosis, a rare condition causing forearm disability, can be effectively treated with osteotomy surgery. Early surgical intervention between ages 4-10 significantly improves hand and forearm function in children.
Area of Science:
- Orthopedics
- Pediatric Surgery
- Genetics
Context:
- Superior radioulnar synostosis is a congenital abnormality impacting forearm function.
- The inheritance pattern of this condition remains unclear.
- This study involved 29 children with 43 instances of superior radioulnar synostosis.
Purpose:
- To investigate the functional impact of superior radioulnar synostosis.
- To evaluate the effectiveness of surgical interventions for this condition.
- To determine the optimal age for surgical correction.
Summary:
- Twenty of the 29 children experienced significant functional disability.
- Fourteen children underwent surgical correction, including Judet's osteotomy and distal radius osteotomy.
- Surgical procedures involved positioning the dominant hand in the position of function and the affected forearm in 30-40 degrees of supination, secured with pins and plaster splints.
Impact:
- All patients demonstrated improved forearm and hand use post-surgery.
- Surgical correction is recommended between the ages of 4 and 10 for optimal functional outcomes.
- Early surgical intervention can lead to substantial functional improvement in affected children.
Abstract:
Superior radioulnar synostosis is a rare abnormality which frequently gives rise to functional disability. Its pattern of inheritance is uncertain. We have studied 29 children, 18 boys and 11 girls, who had a total of 43 such synostoses. Twenty children had significant functional disability. Fourteen required operation, 10 undergoing a Judet's osteotomy and 4 osteotomy of the lower end of the radius. The dominant hand was placed in the position of function, and the other in 30-40 degrees of supination. The osteotomies were secured by pins and supported in a plaster splint. Use of the forearm and hand was improved in all cases. Operation is best carried out between the ages of 4 and 10, and a useful functional improvement can be expected.
