| Objective To investigate the effect of robot-assisted internal fixation on acetabular fracture.Methods Clinical data of 33 patients with acetabular fractures admitted to Wuhan Fourth Hospital from January 2019 to August 2020 were analyzed by retrospective case-series study, including 19 males and 14 females. The age ranged from 43 to 62 years [(56.3±1.1) years]. According to Judet-Letournel classification, there were 11 cases of anterior column fracture, 7 cases of posterior column fracture, 7 cases of transverse fracture, 6 cases of T-shaped fracture, and 2 cases of anterior column plus posterior half transverse fracture. According to AO classification, there were 11 cases of 62-A3, 7 cases of 62-A2, 7 cases of 62-B1,6 cases of 62-B2 and 2 cases of 62-B3. Tinavi orthopedic robot assisted percutaneous screw fixation. The operation time, intraoperative blood loss, length of hospital stay and time of bone union were recorded. Wound healing and complications were observed. The quality of fracture reduction was evaluated by Matta reduction criterion, and functional recovery was evaluated by Harris functional score 1 year after surgery.Results All patients were followed up for 6-12 months [(9.3±1.7) months]. The operation time was 1.3-2.2 h [(1.7±0.3) h], intraoperative blood loss was 70-190 mL [(152.3±25.2) mL], length of hospital stay was 7-12 d [(9.7±1.2) d], and bone union time was 14-18 weeks [(15.4±1.1) weeks]. All surgical incisions were stage I healed. None of the patients had complications such as incision infection, deep venous thrombosis of lower limbs, fat embolism, screw penetration of hip joint, internal fixation failure and re-displacement of fracture, traumatic arthritis, necrosis of femoral head, etc. According to Matta reduction standard, 27 cases of fracture were anatomically reduced and 6 cases were satisfied with reduction. Harris functional score was excellent in 24 cases, good in 7 cases and fair in 2 cases, with an excellent and good rate of 93.9%.Conclusion Robot-assisted percutaneous screw fixation for acetabular fracture has the advantages of less surgical trauma, high accuracy of screw placement and fewer complications, which is conducive to rapid postoperative recovery. |
