Patients & Methods: Eleven patients (6 females and 5 males) with delayed, neglected proximal humerus fractures were included in this study, conducted between March 2015 </span><span>and </span><span>December 2019.</span><span> </span><span>Average age of the patients was 57 years (range: 41 to 67 yrs). All patients were treated with the debridement, decortication and shingling of the bone at the site of the fracture followed by using an endosteal fibular strut graft, corticocancellous bone grafts and stabilization with locking plate. The patients were followed</span><span> </span><span>up for a mean time of 16.3 months (range: 13 </span><span>to </span><span>40 months). The patient outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand Questionnaire, and the modified scoring system of Constant and Murley. </span><b><span>Results</span></b><b><span>:</span></b><b><span> </span></b><span>Union at the fracture site was achieved in all patients at a mean </span><span>of </span><span>8.5 months (range: 6 to 11 months). The DASH score improved from an average pre-operative score of 71.1 (range: 64 to 78) to an average post-operative score of 25.2 (range: 21 to 35) at the final follow-up. Albeit with a small sample size of n</span><span> </span><span>=</span><span> </span><span>11, this difference was found to be statistically significant (p</span><span> </span><span><</span><span> </span><span>0.05). The CM score improved from an average pre-operative score of 33.2 (range: 20 to 48) to an average post-operative score of 66.8 (range: 59 to 72) at the final follow-up. This difference was also found to be statistically significant in this patient cohort (p</span><span> </span><span><</span><span> </span><span>0.05). The results were excellent in 3 patients, good in 6 and moderate in 2. </span><b><span>Conclusions</span></b><b><span>:</span></b><b><span> </span></b><span>An endosteal fibular strut, subperiosteally placed cortico-cancellous grafts with a locking plate fixation helps in biological healing of neglected fractures of proximal humerus.</span> 收起
