Proximal Humerus Reconstruction in Skeletally Immature Patients

Area of Science:

• Orthopedic Surgery
• Pediatric Oncology
• Reconstructive Surgery

Background:

• Proximal humerus reconstruction after cancer surgery is complex, especially in skeletally immature patients.
• Factors like remaining limb growth and humerus size complicate surgical options and fixation.
• Limb length discrepancy and humerus size impact aesthetics, function, and implant choices.

Purpose of the Study:

• To review and compare various proximal humerus reconstruction techniques for skeletally immature patients.
• To aid surgeons and patients in preoperative planning for limb salvage surgery.
• To highlight unique reconstructive options for young patients with remaining growth potential.

Main Methods:

• Review of current literature on proximal humerus reconstruction methods.
• Analysis of reconstruction options including endoprostheses, allografts, and autografts.
• Evaluation of specialized techniques for skeletally immature patients.

Main Results:

• Multiple reconstruction options exist, each with specific advantages and disadvantages.
• Techniques like vascularized fibular epiphyseal transfer and expandible endoprostheses address unique pediatric challenges.
• The choice of reconstruction impacts function, durability, stability, and complication rates.

Conclusions:

• Surgical reconstruction of the proximal humerus in growing children requires careful consideration of unique factors.
• A range of reconstructive strategies, including novel limb salvage options, are available.
• Informed decision-making is crucial for optimizing functional and aesthetic outcomes in these complex cases.
