Insights
Hip arthroscopy successfully treated hereditary multiple exostoses in two children. This minimally invasive approach removed painful hip lesions, preserving joint function and avoiding risks associated with traditional surgery.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Skeletal Dysplasias
Background:
- Hereditary multiple exostoses (HME) is a genetic disorder causing bone overgrowths.
- Exostoses in the acetabular fossa can lead to hip pain and restricted motion.
- Conventional surgical options carry risks like femoral head necrosis.
Observation:
- Two pediatric patients (9 and 11 years old) with HME presented with hip pain and limited range of motion due to acetabular exostoses.
- Exostoses were primarily located in the left hip's acetabular fossa.
- The lesions impacted the patients' daily activities and joint mobility.
Findings:
- Hip arthroscopy was utilized to excise the exostoses.
- The procedure preserved articular surfaces and the Y cartilage.
- Both patients experienced complete pain resolution and restored normal range of motion post-surgery.
Implications:
- Hip arthroscopy offers a viable, less invasive alternative for treating acetabular exostoses in pediatric HME patients.
- This technique mitigates the risks of hip dislocation and femoral head necrosis associated with open surgery.
- These cases highlight a novel application of hip arthroscopy in managing complex pediatric skeletal conditions.
Abstract:
The cases of 2 children (9 and 11 years old) with hereditary multiple exostoses disease are presented. The lesions were located primarily in the acetabular fossa of the left hip and caused pain and limitation of range of motion. Hip arthroscopy was performed to remove the exostoses without damaging the articular surfaces and the Y cartilage. After the procedure, the pain disappeared and normal range of motion was recovered for both children. Conventional surgery would have required hip dislocation to access these lesions with an increased risk of femoral head necrosis. These cases constitute a new and interesting application of hip arthroscopy.
