“…There are different surgical techniques used to treat humeral nonunion. [1,8,13,[17][18][19][20] These surgical techniques have been proposed to ensure the functional performance of upper extremity movements and bone union. Many authors have suggested the plate fixation method as the gold-standard treatment owing to its compression properties and maximum rotational stability.…”

“…Clinical studies on anatomical, biomechanical, and primary traumas have been reported on this nail. [11][12][13] To the best of our knowledge, there are no clinical studies on using the InSafeLOCK ® nail to treat nonunion of humeral shaft fractures. In the present study, we hypothesized that InSafeLOCK ® humeral nails could be used safely in cases of nonunion.…”

Objectives: This study aims to evaluate the clinical and functional results of patients treated with InSafeLOCK® humeral nail and iliac crest autograft for humeral nonunion. Patients and methods: A total of 15 patients (11 males, 4 females; mean age: 52.1±15.3 years; range, 31 to 78 years) who were followed conservatively for humeral fractures and operated with the InSafeLOCK® humeral nail and iliac bone graft in our center between June 2018 and January 2020 were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, operative data, and pre- and postoperative Visual Analog Scale (VAS), Disabilities of the Arm, Shoulder, and Hand (DASH), and Constant-Murley Scores (CMS) were recorded. Results: The mean time from injury to nonunion treatment was 10.9±1.6 months. Five patients had atrophic, eight patients had oligotrophic, and two patients had hypertrophic nonunion. Preoperatively, the mean DASH was 37.7±9.1, the mean CMS was 69.7±6.3, and the mean VAS was 3.8±0.7. In all patients, union was achieved. The mean operation time was 59.0±16.2 min. The mean postoperative DASH score was 16.1±8.7, CMS 87.4±3.4, and VAS score 0.8±0.7. Regarding the shoulder joint, the mean abduction was 164.7±11.3 degrees, the mean internal rotation was 82.0±6.8 degrees, the mean external rotation was 81.3±8.3 degrees, and the mean flexion was 162.0±12.1 degrees. During follow-up, complications such as vascular-nerve injury, reflex sympathetic dystrophy, screw migration or loosening, implant failure, and loss of reduction did not occur in any of our patients. Conclusion: Considering the satisfactory functional and radiological results, the InSafeLOCK® humeral nail can be used safely in humeral nonunions.
