One-bone forearm procedure for partial defect of the ulna.

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Limb reconstruction

Background:

• Partial defects of the ulna in growing children present significant orthopedic challenges.
• Restoring forearm stability and function is crucial for pediatric patients.

Observation:

• Two pediatric cases with partial ulna defects were treated using the one-bone forearm procedure.
• Follow-up periods were 1 and 5 years, respectively.

Findings:

• Successful treatment was achieved, establishing stable elbow and forearm structures through proximal ulna and distal radius synthesis.
• Cosmetic and functional improvements were observed, despite some pronation-supination limitation.
• Longitudinal growth in the affected forearm was maintained post-surgery.

Implications:

• The one-bone forearm procedure is a viable option for managing partial ulna defects in pediatric patients.
• This surgical technique can lead to satisfactory functional and cosmetic outcomes.
• Maintaining longitudinal bone growth is a key benefit for pediatric limb development.
