en شانه / آرنج Shoulder / Elbow گزارش مورد Case Report <div style="text-align: justify;"><span style="font-size:14px;"><span style="font-family:Tahoma;"><span style="line-height:2;"><b>Background</b>: Pure fractures of the anatomical neck of the humerus are rare and potentially serious injuries due to the risk of complications such as avascular necrosis and functional impairment. When associated with fractures of the lesser tuberosity, management becomes more complex and requires precise surgical intervention.<br> <b>Case Presentation</b>: We report two cases of young men who sustained a shoulder injury following a falling down from a high height. Clinical examination revealed severe pain, swelling, and restricted range of motion. Radiographic and computed tomography (CT) imaging demonstrated the fracture of the anatomical neck of the humerus with an associated lesser tuberosity fracture. The patients underwent open reduction and internal fixation via a deltopectoral approach. The humeral head was stabilized using Herbert screws, and the lesser tuberosity was fixed with Ethibond sutures. Postoperative rehabilitation included early passive motion and progressive physiotherapy. Follow-ups at 3 and 6 months showed satisfactory fracture union, improved shoulder function, and no evidence of avascular necrosis.<br> <b>Conclusion</b>: Early diagnosis, appropriate surgical fixation by experienced shoulder surgeon, and structured rehabilitation can result in favorable functional outcomes in complex proximal humerus fractures involving the anatomical neck and lesser tuberosity.</span></span></span></div> Proximal humerus fracture, Anatomical neck fracture, Lesser tuberosity, Internal fixation, Shoulder injury 0 0 http://jros.iums.ac.ir/browse.php?a_code=A-10-2736-3&slc_lang=en&sid=1 Mojtaba Khajeh Alizadeh Attar mojtaba.attar75@gmail.com 10031947532846008880 10031947532846008880 No Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Morteza Nakhaei Amroodi drmna@yahoo.com 10031947532846008881 10031947532846008881 No Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Mohammadreza Bahaeddini mrbahaeddini@yahoo.com 10031947532846008882 10031947532846008882 No Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Mohammadmehdi Mahdavifar Mahdavifarmohammadmehdi@gmail.com 10031947532846008883 10031947532846008883 No Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Pouria Tabrizian tabrizian.pouria@gmail.com 10031947532846008884 10031947532846008884 Yes Bone and Joint Reconstruction Research Center, Shafa Orthopedic Hospital, School of Medicine, Iran University of Medical Sciences, Tehran, Iran
