Angular stability locking plates are commonly used in proximal humeral fractures, especially in old patients with osteoporotic bones. These implants show good results in short and midterm follow-up, but complications are not uncommon. Here we present a case report to describe a case of early failure of a proximal angular stability plate implanted in a 72 years old female with a highly unstable two part proximal humeral fracture. An optical and metallurgic analysis was also conducted to study the modalities of failure...

We present a case of a post-surgical complete dislocation after excessive proximal humeral shortening osteotomy performed in a patient operated on for atrophic non-union of a proximal humeral fracture. This complication has not been previously reported. The dislocation occurred due to extensive laxity of the soft tissue envelope, predominantly the deltoid muscle, as well as rotator cuff tear. The reconstructive procedurę consisted of vertical duplication of the capsule, reinforcement of the repair with coracoacromial ligament, tenodesis of the long head of the biceps tendon to the conjoined tendon and distal transfer of the deltoid muscle...

The objective of this study is to analyze the effect of different imaging modalities in treatment decision making in proximal humeral fractures. After evaluation of 116 consecutive proximal humeral fractures, observers were asked to give treatment recommendation (conservative vs. surgery). If surgery was proposed, they were told to select surgery of choice. When 3D imaging was added, complexity of fractures significantly increased (p < 0.001), number of surgeries significantly increased (p < 0...

The PROFHER study is a multicenter randomized controlled trial of 250 out of 1250 patients assessed for eligibility with dislocated proximal humeral fractures with involvement of the surgical neck. These patients were randomized either for surgery or conservative treatment. Patients with comorbidities that precluded surgery, lack of mental capacity, luxation fractures or clear indications for surgery from the authors' perspective were excluded. To evaluate the outcome, standardized self-assessment methods were used (patient reported outcome [PRO]), including the Oxford shoulder score (OSS)...

BACKGROUND: Humerus fractures caused by the throwing motion are extremely rare. They have been reported mostly in recreational adult athletes in their third or later decades of life. A pediatric thrower's fracture is even less common, with few reported cases. The pediatric version of this fracture is located in the proximal to midshaft humerus, distinguishing it from the adult type, which occurs in the middle to distal shaft. CASE REPORT: A 12-year-old male pitcher experienced a "snap" in his right arm while throwing a pitch in a baseball game...

PURPOSE: The gold standard for intramedullary nailing (IMN) in humeral shaft fracture treatment is bipolar interlocking. The aim of this study was to compare clinical and radiographic outcomes in two cohorts of patients treated with IMN with or without distal interlocking. We hypothesized that there was no significant difference between isolated proximal interlocking and bipolar interlocking in terms of consolidation and clinical results. METHODS: One hundred twenty-one acute humeral shaft fractures were retrospectively included in group WDI (without distal interlocking screw, n = 74) or in group DI (with distal interlocking screw, n = 47)...

The most common operative treatment of proximal humerus fractures is internal fixation with fixed-angle locking plates. Although this surgical technique has been refined, a significant failure rate remains. This study aimed to determine whether the number of locking screws in the humeral head affects the biomechanical strength and stability of the construct in bone from elderly individuals. Ten pairs of embalmed cadaveric humeri were osteotomized in a gap model and fixed with periarticular locking plates placed in the standard position...

Introduction: Shoulder dislocation is the most common type of all joints dislocations. It occurs when there is separation in the glenohumeral joint. Posterior dislocation accounts for less than 4% of all shoulder dislocations. In fact, it is misdiagnosed in 60-79% of the patients in the initial presentation. In children a posterior shoulder dislocation is usually caused by a congenital anomaly or in those who have ligamentous laxity. Traumatic posterior shoulder dislocation without fracture of the proximal humeral epiphysis in children is very rare, and only few cases have been reported...

Introduction: Preoperative comorbidity seems to be an important factor for the functional recovery of patients after shoulder replacement, but few studies support this correlation.The purpose of this study was to clinically evaluate the influence of comorbidity in restoring function after shoulder replacement. Methods: We performed a retrospective analysis of shoulder replacement accomplished at our institution from 2005 to 2016 (n = 70). Demographic data, number of comorbidities, preoperative drugs, type of arthroplasty, and postoperative complications were collected...

BACKGROUND: Fractures of the hook of the hamate are rare. Nonoperative management has historically been immobilization in a short arm cast (SAC) without thumb immobilization with a high reported incidence of nonunion. The high prevalence of nonunion following nonoperative treatment may be secondary to motion at the fracture site. The transverse carpal ligament's attachment to the hook of the hamate results in movement at the fracture site during thumb motion. METHODS: A cadaveric study using 8 fresh frozen cadaver arms amputated at the mid-humeral level was performed...

BACKGROUND: To explore the clinical efficacy of 3D printing fracture models to assist in creating pre-contoured plates to treat proximal third humeral shaft fractures. METHODS: We retrospectively identified proximal third humeral shaft fractures treated between February 2012 and February 2015. The patients were divided into two groups according to the treatment procedure: a Synbone group and a 3D-printed group. In the Synbone group, long proximal humeral internal locking system plates were pre-contoured into helical shape on Synbones before surgery, while in the 3D-printed group, they were contoured on 3D-printed bone models...

Most closed humeral shaft fractures can be successfully managed nonsurgically. However, fractures for which closed treatment is unsuccessful are stabilized using either plates or intramedullary nails. There are shortcomings associated with each technique, including the potential complications of nonunion, infection, shoulder pain, and radial nerve injury. Minimally invasive plate osteosynthesis (MIPO), an innovative alternative treatment, is gaining in popularity. This technique is based on the anterior humeral shaft providing a relatively safe surface for plate application, and limited open exposures proximally and distally allow percutaneous insertion of the necessary implant...
