Forearm pseudarthrosis--neurofibromatosis: case report
Clinical Orthopaedics and Related Research
|March 1, 1979
Summary
This case study highlights a challenging pediatric forearm fracture with neurofibromatosis. Surgical intervention for pseudarthrosis is recommended only after skeletal maturity is reached.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Genetic Disorders
Background:
- Neurofibromatosis (NF) is a genetic disorder that can lead to bone abnormalities and increased fracture risk.
- Pediatric long bone fractures, especially in patients with underlying conditions like NF, can present complex challenges in achieving union.
- Pseudarthrosis, or failure of bone to unite, is a significant complication that requires careful management.
Observation:
- A 3 1/2-year-old girl with neurofibromatosis experienced fractures of the radius and ulna.
- Initial conservative treatment and three subsequent surgical attempts failed to achieve union, resulting in persistent pseudarthrosis.
- The patient's forearm was managed non-operatively until skeletal maturity at age 13 1/2.
Findings:
- Delayed surgical intervention using dual onlay tibial bone grafts successfully achieved osseous union in the forearm pseudarthrosis.
- No recurrence of pseudarthrosis was noted at over 3 years post-operatively.
- This case demonstrates the potential for successful surgical union in complex pediatric pseudarthrosis after reaching skeletal maturity.
Implications:
- Postponing surgical management of forearm pseudarthrosis associated with neurofibromatosis until skeletal maturity may improve outcomes.
- This approach may reduce the need for multiple revision surgeries and associated complications in pediatric patients.
- Further research into optimal timing and techniques for managing NF-associated bone defects is warranted.
