Preventing postoperative adhesions after hand tendon repair using acellular dermal matrix

Area of Science:

• Orthopedic Surgery
• Regenerative Medicine
• Biomaterials Science

Background:

• Postoperative tendon adhesions frequently lead to functional deficits and surgical repair failures.
• Preventing adhesions is crucial for restoring optimal hand function after tendon injuries.

Purpose of the Study:

• To evaluate the long-term efficacy of acellular dermal matrix (ADM) in preventing postoperative adhesions following flexor tendon injuries.
• To assess the impact of ADM on joint range of motion and patient satisfaction.

Main Methods:

• A prospective study involving 37 patients (19-65 years) with acute flexor tendon injuries in zones 1 or 2.
• Patients were randomized into two groups: one treated with ADM and a control group without ADM.
• Outcomes including range of motion and patient satisfaction were assessed at a minimum of six months post-surgery.

Main Results:

• The ADM group showed significantly improved range of motion in both the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints compared to the control group (p=0.03 and p<0.05, respectively).
• Total active motion was greater in the ADM group.
• Patient Satisfaction Questionnaire scores were significantly higher in the ADM group (p=0.02).

Conclusions:

• Acellular dermal matrix (ADM) application following tendon repair can significantly enhance surgical outcomes.
• ADM shows potential for improving range of motion and patient satisfaction in tendon injury reconstruction.
