[Minimally-invasive internal fixation for mid-lateral 1/3 clavicle fracture with distal clavicular anatomic locking...

To investigate clinical effects of minimally-invasive internal fixation for mid-lateral 1/3 clavicle fracture with distal clavicular anatomic locking plate.

From February 2016 to March 2017, 32 patients with mid-lateral 1/3 clavicle fractures treated by minimally-invasive internal fixation with distal clavicular anatomic locking plate, including 24 males and 8 females with an average of (42.3±12.7) years old (ranged from 22 to 68 years old). According to Robinson classification, 6 patients were type 2A2, 18 patients were type 2B1 and 8 patients were type 2B2. No vessel and nerve injury occurred before operation. The time from injury to operation ranged from 0 to 6 days with an average of (3.1±1.4) days. Length of bilateral clavicule were compared before and after operation to evaluate fracture reduction. Constant score at 6 months after operation was applied to assess recovery of shoulder function.

Thirty patients were followed up from 11 to 18 months with an average of (13.3±2.2 ) months. No vessel and nerve injury, implant failure, nonunion or delayed union occurred after operation, and facture wound healed at stage I, the time ranged from 8 to 12 weeks with an average of(10.2±1.1) weeks. Shortened length of clavicle decreased from(11.2±3.6) % before operation to (0.4±0.3)% after operation at 2 days. Ten patients removed internal fixation at 8 months after operation without re-fracture occurred after remove plate. Constant score increased from 23.53±5.21 before operation to 94.30±5.60 after operation at 6 months, and 26 patients got excellent results, and 4 good. Patients were satisfied aesthetic degree of scar and shoulder joint function.

Minimally-invasive internal fixation for mid-lateral 1/3 clavicle fracture with distal clavicular anatomic locking plate, which has advantages of less trauma, rapid recover, less scar, could receive good clinical effects and not effect beauty.
