Abstract
For complex and unstable scapular fractures requiring simultaneous fixation of the glenoid neck, the lateral margin of the body, and/or the scapular diaphysis, reconstruction locking plate is difficult to achieve satisfactory fixation. In order to optimize the fixation effect, the newly designed claw-shaped bone plate was designed for fixing such fractures. We also evaluate the clinical effects and follow-up at an average of 1 year after treatment in scapular internal fixation by using reconstruction locking plate and claw-shaped bone plate in complex unstable scapular body and glenoid neck fracture. A retrospective study was conducted from 2018 to 2021, thirty-three patients (27 males and six females) who were defined unstable scapular fractures by Ada-Miller. Fifteen patients (52.86 ± 8.26 years) received claw-shaped bone plate and 18 cases (51.61 ± 11.31 years) received reconstruction locking plate with the intermuscular approach. The clinical effect was evaluated based on the operation time, intraoperative blood loss, surgical complications, clinical healing time and Constant-Murley score (CMS). The data analysis by Student t, Mann-Whitney U test and Pearson's chi squared test. Compared with reconstruction locking plate, the claw-shaped bone plate showed shorter operation time (102.73 ± 18.43 min vs. 156 ± 37.53, P < 0.0001), higher CMS (94.00 ± 4.07 vs. 89.88 ± 5.42, P = 0.02) and no differences between the two groups regarding intraoperative blood loss (208.00 ± 96.45 mL vs. 269.44 ± 120.21, P = 0.12) and clinical healing times (9.96 ± 1.52 vs. 10.05 ± 1.67, P = 0.87). Follow-up were conducted at first, third, 6 and 12 months after surgery. The operation was successful in all patients with no intraoperative complications. For the treatment of complex and unstable scapular neck body fractures, the application of claw-shaped bone plate demonstrated short operation time, better stability of the fracture block, and higher CMS. In the intraoperative and postoperative follow-up showed better clinical results and rehabilitation effects.
