Purpose:
The aim of this study was to assess applicability of arthroscopic technique in intramedullary nail fixation of humerus shaft fractures and to compare with conventional nailing in terms of its effects on perioperative and postoperative intra-articular complication rates as well as on clinical and functional outcomes.
Methods:
This prospective randomized controlled clinical trial included 40 patients (12 females and 28 males) indicated for surgery between either undergo arthroscopy-assisted (Arthroscopy-assisted intramedullary nailing [AIMN]; n = 20) or conventional (Intramedullary nailing [IMN]; n = 20) anterograde intramedullary nailing. Two groups were compared in terms of mean number of fluoroscopic shootings until the guide wire was inserted, time for union, length of hospital stay, and complication rates. Shoulder functions were assessed by Constant and American Shoulder and Elbow Surgeons (ASES) score.
Results:
Groups did not significantly differ in terms of age, gender, and mechanism of injury, length of hospital stay, union rate, and mean union time (p > 0.05). Mean ASES and Constant scores were found to be statistically significantly higher in AIMN group than that in IMN group (p = 0.000 and p = 0.002, respectively). Mean number of fluoroscopic shootings until the guide wire was inserted was 2.15 in AIMN group, which was significantly lower compared to 4.2 of IMN group (p = 0.000).
Conclusions:
Arthroscopy-assisted technique may be an applicable and safe method owing to its cosmetic advantages and more satisfactory postoperative shoulder functions subsequent to less injury to deltoid, rotator cuff, and other soft tissue, as compared to conventional anterograde approach.
