Hemiarthroplasty implantation for proximal humerus fracture is challenging. In case of young demanding patients with functional rotator cuff, humeral head replacement is an option if open reduction internal fixation is not a viable solution. The criteria for success in terms of clinical outcomes and longevity are anatomic healing of the tuberosities and stem positioning (restoring correct height, version, and axis). The purpose of this article is to describe a technique including a new stem guide and a tuberosity anchor "lasso" system for the implantation of hemiarthroplasty in complex proximal humerus fractures...

Capsulolabral reconstruction (Bankart repair) is recommended as the first line treatment in young and functionally demanding active patients with anteroinferior shoulder instability, due to the high tendency to recurrent dislocation. This has become established both for arthroscopic and open primary shoulder stabilization with good clinical outcome; nevertheless, recurrence of dislocation is reported in up to 25% of patients. Risk factors for failed surgery are patient (e.g. young age, male gender and contact sports) and surgery (e...

BACKGROUND: Shoulder arthroplasty is the fastest growing joint replacement surgery in the United States, and optimal postoperative pain management is critical to optimize outcomes for these surgeries. Liposomal bupivacaine (LB) has gained popularity for its potential to provide extended postoperative pain relief with possibly fewer side effects. The goal of this study was to assess the impact of LB compared with continuous interscalene nerve block (CISB) in terms of postoperative pain control, outpatient pain scores, and patient-reported and functional outcomes after shoulder arthroplasty surgery...

Five shoulders in four patients affected by advanced osteonecrosis of the humeral head were treated with autologous concentrated bone marrow grafting. Bone marrow sample was aspirated from the iliac crests, concentrated by a centrifugation technique, and injected into the necrotic site. The shoulders were evaluated radiologically with X-ray scoring and clinically with measurement of range of motion and pain score (visual analogue scale, VAS). The mean follow-up period was 49.4 (range, 24-73) months. The concentration ratio of nucleated cells was calculated and the number of transplanted mesenchymal stem cells (MSC) was estimated by a colony-forming assay...
