Abstract
Avulsion injuries and replantation of the upper arm are particularly challenging in the field of traumatic microsurgery. At present, the functional recovery of the avulsion injuries upper arm after the replantation is generally not ideal enough, and there is no guideline for the surgeries. The aim of this study was to analyze the causes of failure of the upper arm replantation for avulsion injuries, summarize the upper arm replantation’s indications, and improve the replantation methods.
Highlights
Replantation of the avulsed upper arm is challenging in the field of traumatic microsurgery
Upper limb function at one year after the replantation surgery was an average score of 25.2 points, which was considered poor function according to the Chinese Medical Association assessment criteria for upper limb amputation replantation (Table 2)
Because of the longtime of muscle ischemia after replantation of avulsion injury of the upper arm, which will lead to muscle fibrosis and even necrosis, we suggest that the catheter should be used to open the blood of the distal limb for the first time, so as to minimize the ischemic time of the distal limb
Summary
Replantation of the avulsed upper arm is challenging in the field of traumatic microsurgery. The functional recovery of the avulsion injuries over upper arm after the replantation is generally not satisfied enough, and there is no guideline for the surgeries. How to further clarify the indications for surgery, improve surgical techniques, and promote full recovery of patients with upper extremity function are still important issues in the field of limb replantation [4]. Avulsion injuries and replantation of the upper arm are challenging in the field of traumatic microsurgery. The functional recovery of the avulsion injuries upper arm after the replantation is generally not ideal enough, and there is no guideline for the surgeries. Methods: From January 2014 to January 2016, our department had treated 15 cases of trauma caused upper arm avulsion amputation injuries. Skilled microsurgical techniques may improve the success rate of replantation
