To be specific, 12 males and 31 females were reviewed with an average age of 72.0\u2009years (range, 66\u201378\u2009years). All fractures were attributed to trauma and treated for 8.0\u2009days on average (range, 6\u201311\u2009days). As suggested from Neer classification, 21 cases (48.8%, 21\/43) were three\u2010part fractures, and 22 (51.2%, 22\/43) were four\u2010part fractures. To assess the postoperative efficacy, Visual Analog Scale (VAS), American Society of Shoulder and Elbow Surgery Shoulder Joint Score (ASES), Constant\u2013Murley score and radiological examination were adopted. The Neer three\u2010part fracture group and the Neer four\u2010part fracture group were compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There was no significant difference in age, gender, operation time, and follow\u2010up period between Neer three\u2010part fracture group and Neer four\u2010part fracture group. All operations were successfully performed, and the average operation time was 120\u2013170\u2009min, with an average of 141.3\u2009min. Besides, the mean blood loss was 407.0 mL (250\u2013700 mL), and the average intraoperative blood transfusion reached 446.5 mL (400\u2013800 mL). All patients received the follow\u2010up for 6 to 16\u2009months, that is for 10.9\u2009months on average. All patients were discharged in 7\u2009days after operation, and no wound\u2010related complications were identified. In 8\u2009weeks, the greater and lesser tuberosities of all patients healed completely. During the last follow\u2010up, no loosening or dislocation of prosthesis was detected, and the forward elevation of 133.0 (100\u00b0\u2010 165\u00b0), the external rotation of 29.5\u00b0 (20\u00b0\u201335\u00b0), the internal rotation of 46.7\u00b0(30\u00b0\u201360\u00b0), the VAS score of 0.8(0\u20133), the ASES score of 89.1(78.8\u2013100.0) were achieved. Constant\u2010Murley score reached 88.7 (range, 70\u201398). There was no significant difference between Neer three\u2010part fracture group and Neer four\u2010part fracture group (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). A 71\u2010year\u2010old patient developed the symptoms of axillary nerve injury after operation; he recovered completely at 6\u2009weeks after the operation, which had not adversely affected the functional rehabilitation exercise or the stability of the prosthesis. At the follow\u2010up, no other complications (e.g., infection, acromial stress fracture, and scapular notching) were identified in all patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The short\u2010term efficacy of one\u2010stage reverse shoulder arthroplasty to treat complex proximal humeral
