Summary
Chronic pectoralis major tendon (PMT) rupture can be challenging to treat. A novel surgical technique using acellular dermal allograft interposition successfully restored strength in two patients with chronic PMT tears.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Tendon repair
Background:
- Pectoralis major tendon (PMT) ruptures are common in young males, often linked to weightlifting (bench press) or impact sports.
- Delayed diagnosis or misdiagnosis can lead to chronic PMT rupture, presenting a significant treatment challenge.
- Chronic PMT tears require effective surgical strategies to restore shoulder and chest function.
Observation:
- This case series details two patients with chronic pectoralis major tendon ruptures.
- Both patients underwent operative management utilizing an acellular dermal allograft as an interposition graft.
- Post-operative follow-up at 20 and 30 months demonstrated preserved muscle strength.
Findings:
- Patient 1 exhibited 88% of contralateral pectoralis major strength.
- Patient 2 demonstrated 110% of contralateral pectoralis major strength.
- The acellular dermal allograft facilitated successful reconstruction and functional recovery.
Implications:
- The interpositional acellular dermal allograft technique offers a viable solution for chronic pectoralis major tendon ruptures.
- This approach may help restore muscle strength and function in patients with long-standing tendon defects.
- Further research can validate this technique for a broader patient population with chronic PMT tears.
