Purpose: Osteosynthesis of a clavicular fracture can obtain good clinical results even with conservative treatment. The development of surgical techniques and improvements in internal fixation have led to the use of metal plates and screws. Although there are intramedullary nails or minimally invasive plate osteosynthesis that can reduce soft tissue damage, these techniques are not used often because most require a skin incision about the length of the metal plate to be inserted. This study compared the postoperative pain to determine the appropriate injection depth. Materials and Methods: A prospective, single-institute, single-blind, randomized study was designed. The patients in the study had clavicular fractures and who underwent the removal of implant. The patients judged to have difficulty indicating pain were excluded. Ropivacaine was injected between plate fixation and muscle suturing. The visual analog scale (VAS) pain score, patient-controlled analgesia (PCA) use, and additional pain medication usage were measured after surgery and every 4 hours. Results: Thirty-four clavicle shaft fracture patients were classified into 16 patients in the subcutaneous injection group and 18 in the muscle injection group. Seventeen implant removal patients were divided into eight patients in the subcutaneous injection group and another nine in the muscle injection group. In the fracture group, the mean VAS for the subcutaneous injection group was 4.20±2.68 immediately after surgery, 4.47±1.85 at 4 hours, 1.93±1.44 at 24 hours, and 1.60±1.35 at 48 hours. The mean VAS for the muscle injection group was 4.23±1.59 immediately after surgery, 3.00±1.47 at 4 hours, 1.69±1.03 at 24 hours, and 1.31±1.11 at 48 hours; the mean VAS score was not statistically significant in the two groups (p=0.332). In the implant removal group, the mean VAS for the subcutaneous injection group was 4.75±1.58 immediately after surgery, 3.75±1.04 at 4 hours, 1.75±0.89 at 24 hours, and 1.75±0.89 at 48 hours. The mean VAS for the muscle injection group was 3.78±1.20 immediately after surgery, 3.22±0.83 at 4 hours, 1.89±1.17 at 24 hours, and 1.11±1.01 at 48 hours; the mean VAS score was not statistically significant in the two groups (p=0.181). Conclusion: The postoperative VAS pain score and PCA usage were not statistically significant regardless of the ropivacaine injection site in clavicular surgery, but each group had significantly different VAS pain scores and PCA usage according to time after surgery. In addition, the muscle injection group tended to have a lower average VAS than the subcutaneous injection group in the implant removal patient group. [ABSTRACT FROM AUTHOR]
