Abstract
BACKGROUND
Severe proximal humerus comminuted fractures are often accompanied by medial calcar comminuted fractures and loss of medial support, which are important factors that lead to internal fixation failure. The appropriate treatment for proximal humerus comminuted fractures has not been established. Therefore, this study assessed the outcomes of using a fibular autograft with locking plates to treat severe proximal humerus comminuted fractures.
AIM
To investigate the outcomes of using a fibular autograft with locking plates to treat severe proximal humerus comminuted fractures.
METHODS
This retrospective, comparative cohort study included two groups of patients. Group 1 comprised 22 patients and group 2 comprised 25 patients with complete follow-up data. Group 1 was treated with a fibular autograft with open reduction and locking plates to enable internal fixation. Group 2 was treated with open reduction and locking plates to enable internal fixation. The intraoperative blood loss volume from the shoulder wound, operative time, shoulder wound pain, bone fracture healing time, Constant-Murley score of the shoulder joint, preoperative Holden walking function score, Mallet score of the shoulder joint, and humeral neck-shaft angle during surgery of the two groups were compared, and the differences were analysed using an independent sample t-test.
RESULTS
Group 1 had a shorter mean operative time than group 2 (2.25 ± 0.30 h vs 2.76 ± 0.44 h; P = 0.000). Group 1 had a lower shoulder wound pain score on the first day after surgery than group 2 (7.91 ± 1.15 points vs 8.56 ± 1.00 points; P = 0.044). Group 1 had a shorter fracture healing time than group 2 (2.68 ± 0.48 mo vs 3.64 ± 0.64 mo; P = 0.000). Group 1 had higher Constant-Murley scores of the shoulder joint at 3, 6, and 12 mo after surgery than group 2 (76.64 ± 4.02 points vs 72.72 ± 3.02 points, 86.36 ± 3.53 points vs 82.96 ± 3.40 points, and 87.95 ± 2.77 points vs 84.68 ± 2.63 points, respectively; P = 0.000, 0.002, and 0.000, respectively). Group 1 had higher Mallet scores of the shoulder joint at 3, 6, and 12 mo after surgery than group 2 (10.32 ± 0.57 points vs 9.96 ± 0.54 points, 13.36 ± 1.00 points vs 12.60 ± 0.87 points, and 13.91 ± 0.75 points vs 13.36 ± 0.70 points, respectively; P = 0.032, 0.007, and 0.013, respectively).
CONCLUSION
Using locking plates with a fibular autograft can recreate medial support, facilitate fracture healing, and improve shoulder function; therefore, this may be an effective treatment option for severe proximal humerus comminuted fractures.
