A Systematic Review of Anti-Adhesion Agents in Hand Trauma

Adhesions following hand surgery are common, leading to stiffness, which compromises the functional outcomes for the patient. The objective of this study was to conduct a systematic review to analyze the role of antiadhesive barriers in surgery for hand trauma. A comprehensive literature search was conducted using PubMed/MEDLINE, Embase and the Cochrane Central Register of Controlled Trials, in line with the Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines. The inclusion criteria included both randomized and non-randomized control studies in patients aged 18 or over, with the intervention of an anti-adhesive barrier compared against traditional repair without a barrier in patients with hand trauma, including nerve, fracture, and tendon injury. The primary outcome measure of interest was range of movement (ROM) after operative surgery. Secondary outcomes of interest included further surgery, reported stiffness, complications, quality of life, and time to return to work. A total of 8450 records were identified; 7 studies fulfilled the eligibility criteria and were included. Seven anti-adhesive barriers were included in the review. Three agents (amnion, MASTBiosurgery Surgiwrap antiadhesive film, and acellular dermal matrix [ADM]) demonstrated statistically significant improvements in ROM postoperatively; however, all 3 studies demonstrated a risk of bias. This review highlights the paucity of high-quality studies demonstrating any clear advantage of using anti-adhesive barriers in hand surgery; however, there is some evidence to suggest that amnion, the MAST adhesion barrier film and ADM may have favorable results as an antiadhesive barrier in hand surgery, but further high-quality research is required to quantify this effect.
