Periprosthetic humerus fractures are relatively uncommon occurrence that can be difficult to manage nonoperatively. Locking plate technology has enhanced the surgical management of these fractures. However, adequate fixation around the stem remains of some concern. We describe an osteosynthesis technique using a locking plate utilizing eccentrically placed screw holes to place "skive screws" in the proximal end of the plate to achieve fixation around the stem of the implant. A clinical series of 5 consecutive patients treated with this technique is presented with an average follow-up of 29 months (range, 12-48)...

OBJECTIVES: Accurate characterisation of fractures is essential in fracture management trials. However, this is often hampered by poor inter-observer agreement. This article describes the practicalities of defining the fracture population, based on the Neer classification, within a pragmatic multicentre randomised controlled trial in which surgical treatment was compared with non-surgical treatment in adults with displaced fractures of the proximal humerus involving the surgical neck...

Cartilage canals (CCs) are microscopic structures involved in secondary ossification centers (SOCs) development. The features of CCs were investigated in the humeral and femoral proximal epiphyses of small-sized newborn dogs (from premature to 28 days after birth) with histochemical and immunohistochemical approaches. Masson's Trichrome revealed a ring-shaped area around CCs, which changes in colour from green (immature collagen) to red (mature collagen) as ossification progresses; perichondrium staining always matched the ring colour...

BACKGROUND: Although recurrent anterior shoulder instability (RASI) is a common condition in young patients, no studies to date have measured the 3-dimensional (3D) locked position of the glenohumeral joint during an anterior dislocation. Therefore, our goal was to estimate it with 3D computed tomography (CT) scans. METHODS: Patients in this prospective observational study were separated in 3 groups: normal laxity, hyperlaxity, and epilepsy. They were characterized by questionnaires (Western Ontario Shoulder Instability Index, 11-item version of the Disabilities of the Arm, Shoulder and Hand, and Beighton Laxity Score), and a CT scan revealing bipolar bone defects...

INTRODUCTION: The shoulder arthroplasty brings satisfaction to patients in terms of quality of life and indolence. However whether anatomic implant or reverse, it does not escape from the loosening of the glenoid component. Moreover, optimal implantation is required to ensure the functional outcome without shortening of the arm. The purpose of this study is obtain CT scan evaluation of the glenoid bone stock in order to optimize glenoid component implantation and obtain a reference to determine optimal humeral component placement in case of humeral proximal fracture...

Enthesopathy is considered to be an osseous phenomenon, either disease-specific or bone-site specific, which occurs at the enthesis of bone. Upon routine cadaveric dissection of the glenohumeral region in two Caucasian females, enthesopathy of the right proximal humerus was observed unilaterally in both cases. Case 1 exhibited an inconsistent pattern of bony protuberances and crests dispersed across the lesser and greater tuberosities of the right humeral head. Varying degrees of ossification of the distal subscapularis muscle was also observed...

The treatment of displaced proximal humerus fractures is challenging and complex, as its success is predicated on multiple factors. While it is clear that a majority of proximal humerus fractures may be treated nonoperatively, it is less clear which patients benefit from surgical management. The PROFHER trial, a randomized controlled study, used patient-reported outcomes to compare surgical to nonsurgical management of displaced proximal humerus fractures. The purpose of this review is to highlight the strengths and weaknesses of the PROFHER trial and to assess the validity of its conclusion in the context of existing literature...

AIMS: Despite the expansion of arthroscopic surgery of the shoulder, the open deltopectoral approach is increasingly used for the fixation of fractures and arthroplasty of the shoulder. The anatomy of the terminal branches of the posterior circumflex humeral artery (PCHA) has not been described before. We undertook an investigation to correct this omission. PATIENTS AND METHODS: The vascular anatomy encountered during 100 consecutive elective deltopectoral approaches was recorded, and the common variants of the terminal branches of the PCHA are described...

Pseudoarhtrosis is a relatively frequent complication of fractures, in which the lack of mechanical stability and biological stimuli results in the failure of bone union, most frequently in humerus and tibia. Treatment of recalcitrant pseudoarthrosis relies on the achievement of satisfactory mechanical stability combined with adequate local biology. Herein we present two cases of atrophic pseudoarthrosis that received a Tissue Engineering Product (TEP) composed of autologous Bone Marrow-derived Mesenchymal Stromal Cells (BM-MSC) combined with deantigenised trabecular bone particles from tissue bank...

In order to minimize the bias of Constant score we modified the allocation of strength subscore. One hundred and two patients with 3- and 4-part proximal humerus fractures were treated using locking plate fixation and followed up for > 1 year. The clinical outcomes were assessed by DASH score abbreviated Constant score (AbbCS strength item excluded) modified Constant score (ModCS with 12-pound strength) and original Constant score (CS with 25-pound strength). The satisfaction rate was determined for each scoring instrument...

BACKGROUND: Limb salvage following the resection of tumor from the proximal part of the humerus, poses many challenges, and there is no consensus regarding the best reconstructive technique after proximal humerus resection. The aim of this study was to evaluate the effect of anteromedial placing of the plate in the absence of deltoid muscle and cement augmentation on the functional outcome, complication rate and survival of proximal humerus allograft reconstruction. PATIENTS AND METHODS: A number of 36 osteoarticular allograft reconstructions of proximal humerus were included in final study...

PURPOSE: Avascular necrosis (AVN) of the humeral head is a devastating complication of proximal humeral fracture (PHF) that often results in long-term morbidity for the patient. Rates of AVN depend on the number of fracture fragments and are highly variable. The literature suggests that timely stable and anatomic reduction may decrease the rate at which AVN develops after PHF. To our knowledge, there is no literature published investigating a temporal relationship between the timing of PHF fixation and rates of AVN...

Shoulder injuries in pediatric athletes are typically caused by acute or overuse injuries. The developing structures of the shoulder lead to injury patterns that are distinct from those of adult athletes. Overuse injuries often affect the physeal structures of the proximal humerus and can lead to pain and loss of sports participation. Shoulder instability is common in pediatric athletes, and recurrence is also a concern in this population. Fractures of the proximal humerus and clavicle are typically treated with conservative management, but there is a trend toward surgical intervention...
