Abstract
Background:
The best option for the treatment of Neer type IIB lateral clavicle fractures remains controversial. The aim of this study was to compare outcomes and complications between pre-contoured locking plate osteosynthesis (PLPO) and coracoclavicular stabilization (CCS) using a TightRope for the treatment of type IIB fractures.

Methods:
Forty-six consecutive type IIB fractures were treated with PLPO (17 cases) or CCS (29 cases). The mean follow-up period was 33.7 months (range, 12–144 months). Radiographic outcomes were evaluated using serial plain radiographs. Clinical outcomes were evaluated using the University of California, Los Angeles (UCLA) score, the American Shoulder and Elbow Surgeons (ASES) score, and subjective shoulder value (SSV).

Results:
Of the 46 cases, complete bony union within 6 months after surgery was achieved in 42 cases (91.3%). The union rate was 100% (17/17) in the PLPO group and 86.2% (25/29) in the CCS group, showing a statistically significant difference (p = 0.043). No significant differences in terms of UCLA score (32.8 vs. 32.1), ASES score (93.2 vs. 90.8), or SSV (89.1% vs. 90.3%) were observed between the PLPO and CCS groups. The complication rates were 17.6% (3/17; 2 cases of screw breakage and 1 case of stiffness) in the PLPO group and 37.9% (11/29; 4 cases of nonunion, 3 cases of stiffness, 2 cases of skin irritation, 1 case of superficial infection, and 1 case of coracoid button migration) in the CCS group, showing no statistically significant difference (p > 0.05). Four cases with nonunion after CCS did not require reoperation because they had good to excellent clinical outcomes without radiographic progression.

Conclusions:
Although a higher nonunion rate was observed in the CCS group compared with the PLPO group, satisfactory clinical outcomes were obtained for both groups. Both techniques can be regarded as useful options for the treatment of Neer type IIB lateral clavicle fractures.
