en Effect of Amniotic Membrane Nerve Wrapping in Final Results of Traumatic Peripheral Nerve Repair تخصصي Special مقالات اصيل Original Article BACKGROUND Preventing perineural adhesions and scars formation in the traumatic peripheral injuries is very important on the recovery process. We aimed to evaluate the effect of using the amniotic membrane wrapping on the results of surgical treatment of damaged peripheral nerves. METHODS This cohort study included 30 patients with symptoms of acute peripheral nerve injuries due to penetrating trauma in the forearm or wrist in January 2019 to November 2020 referred to the Hand and Microsurgery Department, 15 Khordad Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran. In 15 patients, after nerve repair, amniotic membrane coverage was used around the nerve, all patients were followed for 12 months. Ultrasound study for neuroma formation and nerve regeneration was determined based on EMG and NCV findings. The modified Medical Research Councile classification (MRCC) was used to evaluate of motor and sensory recovery. RESULTS In the amniotic membrane wrapping group, all patients had nerve regeneration and functional nerve recovery occurred after 12 months. In the control group, 5 patients (33.4%) did not have nerve recovery and had functional and sensory impairment. In terms of functional capabilities; there was a significant difference in pinch strength, grip power and MRCC scoring between the two groups. Moreover, the mean volume of neuroma in these patients who used amniotic membrane covering was 2.7 mm3 and in the control group, it was 3.9 mm3 (P=0.001). Five patients who did not have a damaged nerve, the neuroma volume was 4.8 ± 0.9 mm3. CONCLUSION The use of amniotic membrane covering is effective methods in the improve results of peripheral nerve repair and nerve function recovery.   Amniotic membrane, Peripheral nerve, Nerve regeneration, Functional recovery 90 94 http://wjps.ir/browse.php?a_code=A-10-761-2&slc_lang=en&sid=1 Soraya Shahrokh Shahraki 100319475328460012912 100319475328460012912 No 1.
