[Corrective osteotomy of the distal radius]

Area of Science:

• Orthopedic Surgery
• Traumatology
• Radiology

Background:

• Malunited distal radius fractures can lead to significant functional impairment.
• Restoring anatomical alignment is crucial for optimal wrist function.

Purpose of the Study:

• To evaluate outcomes of corrective osteotomy for malunited distal radius fractures.
• To assess the degree of correction and its maintenance post-bone union.
• To compare clinical and radiographic results with existing literature.

Main Methods:

• Retrospective analysis of 16 patients (2002-2004) undergoing corrective osteotomy.
• Surgical technique: radius opening-wedge osteotomy with bone graft and T-plate fixation.
• Clinical evaluation using the New York Orthopaedic Hospital Wrist Rating Scale; radiographic assessment of radius length, ulnar inclination, and tilt.

Main Results:

• Achieved up to 9 mm of radius lengthening.
• Demonstrated correction of ulnar inclination by up to 34 degrees.
• Corrected dorsal deformity by up to 24 degrees, with 80% excellent/good results.

Conclusions:

• Corrective osteotomy with bone grafting is a viable treatment for malunited distal radius fractures.
• Indicated for active, younger patients with symptomatic malunion and radiographic evidence.
• Thorough pre-operative planning and radiographic assessment are essential for successful outcomes.
