Robot-assisted versus traditional surgery in the treatment of intertrochanteric fractures: a meta-analysis

Intramedullary nail fixation of intertrochanteric fractures assisted by orthopedic surgical robot navigation is a new surgical method, but there are few studies comparing its efficacy with traditional intramedullary nail fixation. We aimed to assess whether robot-assisted internal fixation confers certain surgical advantages through a literature review. PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wan fang Data Knowledge service Platform were searched to collect randomized and non-randomized studies on patients with calcaneal fractures. Five studies were identified to compare the clinical indexes. For the clinical indexes, the technology of robot-assisted is generally feasible, in time to operation, intraoperative fluoroscopy times, blood loss, pine insertion, tip apex distance (TAD), and Harris score (P < 0.05). However, on the complication and excellent and good rate after operation did not show good efficacy compared with the traditional group (P > 0.05). Based on the current evidence, For the short-term clinical index, the advantages of robot-assisted are clear. The long-term clinical effects of the two methods are also good, but the robot-assisted shows better. However, the quality of some studies is low, and more high-quality randomized controlled trials (RCTs) are needed for further verification.
