Objective: To investigate the feasibility and clinical effect of the treatment of NeerⅡb distal clavicular fracture with locking plate under arthroscopy.
Methods: Between June 2018 and September 2022, the medical records of 15 patients with NeerⅡb distal clavicular fracture treated with locking plate under arthroscope were retrospectively analyzed, including 9 males and 6 females, aged from 25 to 57 years old with an average of (42.50±7.75) years old, 5 left shoulder, 10 right shoulder, and duration of the disease ranged from 4 to 7 days with an average of (5.16±0.98) d. Visual analog score (VAS), Constant-Murley shoulder joint score scale and Neer standard score were used before operation, 1 month after operation and the last follow-up.
Results: All patients successfully completed the treatment of NeerⅡb distal clavicular fracture with locking plate under arthroscopy, with the operation time ranging from 0.3 to1.0 h with an average of (0.55±0.24) h. All patients were healed at stageⅠ. The follow-up time ranged from 6 to 15 months with an average of (9.2±2.8) months. The preoperative VAS score was 7.23±0.67, the Constant-Murley shoulder joint score was (19.57±0.91), and the Neer standard score was (11.27±1.12);The VAS score was (1.56±0.81), the Constant-Murley shoulder joint score was (52.62±1.54), and the Neer standard score was (61.98±2.99) in the first month after operation;At the last follow-up, the VAS was (0.42±0.54), the Constant-Murley shoulder joint score was (91.24±1.97), and the Neer standard score was (93.24±3.38). The difference between VAS, Constant-Murley shoulder joint score and Neer standard score was statistically significant at one month postoperative and preoperative (P<0.05), and the difference between the last follow-up visit and one month postoperative was statistically significant (P<0.05).
Conclusion: The treatment of NeerⅡb distal clavicular fracture with locking plate under arthroscope can restore the function of shoulder joint, with definite curative effect and feasibility.
