Corrective Osteotomy for Intra-Articular Distal Humerus Malunion

Area of Science:

• Orthopedic Surgery
• Traumatology
• Reconstructive Surgery

Background:

• Intra-articular distal humerus malunion can lead to significant disability.
• Corrective osteotomy aims to improve function, reduce pain, and prevent secondary osteoarthritis.
• This study presents indications, planning, technique, and long-term results of this procedure.

Purpose of the Study:

• To evaluate the efficacy of intra-articular corrective osteotomy for distal humerus malunion.
• To provide guidelines for pre-operative planning and surgical technique.
• To report long-term outcomes in a series of patients.

Main Methods:

• A consecutive series of six patients with intra-articular distal humerus malunion were included.
• Mean follow-up duration was 88 months.
• Elbow function was assessed using standardized questionnaires and classification systems.

Main Results:

• All osteotomies healed successfully, with three patients experiencing treatable postoperative complications.
• Significant improvements in range of motion and high patient satisfaction were observed.
• Elbow performance scores were consistently good to excellent, with age and osteoarthritis severity predicting long-term outcomes.

Conclusions:

• Intra-articular corrective osteotomy is a valuable treatment for malunited distal humerus fractures.
• The procedure is particularly recommended for young patients with minimal osteoarthritis and functional deficits.
• Favorable long-term function and quality of life can be achieved with appropriate patient selection.
