Clinical Effect Of Using Multiloc (R) Nails To Treat Four-Part Proximal Humeral Fractures

ObjectiveThis study was performed to evaluate the clinical effect of MultiLoc (R) nails (DePuy Synthes, Raynham, MA, USA) on the treatment of four-part proximal humeral fractures (PHFs).MethodsFrom January 2014 to January 2018, 32 patients with four-part PHFs were treated with intramedullary MultiLoc (R) nails in our hospital. The operation time, bleeding volume, postoperative X-ray findings, and fracture healing status were recorded and analyzed. At the end of follow-up, the clinical outcome was evaluated based on the visual analog scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) shoulder score, Constant-Murley score (CMS), and occurrence of any complications.ResultsAmong all patients, the average operation time was 124.5 minutes (range, 91-152 minutes), the average amount of bleeding was 90 mL (range, 55-150 mL), and the fracture healing rate was 100%. At the end of follow-up, the mean VAS score was 1.6 +/- 0.4, mean ASES score was 84.4 +/- 6.3, and mean CMS was 70.3 +/- 6.1; no serious complications had occurred; and the patients exhibited good recovery of shoulder function.ConclusionsMultiLoc nails (R) can be applied to the treatment of four-part PHFs. This surgical fixation method has no obvious complications and helps to restore shoulder function.
