[Treatment progress on proximal humerus fracture with proximal humerus cage]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Trauma Care

Background:

• Proximal humerus fractures are increasingly common shoulder injuries, necessitating surgical intervention.
• Current surgical methods like locking plates, fibular strut allografts, and arthroplasty have significant limitations.
• Locking plates risk screw penetration and reoperation; allografts cause surgical trauma; arthroplasty has a steep learning curve and high cost.

Purpose of the Study:

• To review traditional and emerging treatment modalities for proximal humerus fractures.
• To evaluate the efficacy and complication rates of various surgical interventions.
• To introduce the proximal humerus cage as a novel treatment option.

Main Methods:

• Literature review of established and recent surgical techniques for proximal humerus fractures.
• Comparative analysis of complication rates, including intra-articular screw penetration, reoperation, surgical trauma, and learning curve.
• Exploration of the biomechanical advantages and clinical application of the proximal humerus cage.

Main Results:

• Locking plate fixation shows high rates of intra-articular screw penetration and reoperation.
• Fibular strut allografts provide support but involve significant surgical trauma and vascular risks.
• Arthroplasty is effective for complex cases but demands extensive training and incurs high costs.
• The proximal humerus cage demonstrates a 3D structure for robust load-bearing and flexible screw placement, potentially reducing complications.

Conclusions:

• The proximal humerus cage presents a promising new option for treating proximal humerus fractures.
• This innovative approach may decrease postoperative complications and enhance patient safety during rehabilitation.
• A thorough understanding of treatment options is crucial for optimal patient outcomes in proximal humerus fracture management.
