Locking plates are increasingly used to surgically treat proximal humerus fractures. Knowledge of the bone quality of the proximal humerus is important. Studies have shown the medial and dorsal aspects of the proximal humeral head to have the highest bone strength, and this should be exploited by fixation techniques, particularly in elderly patients with osteoporosis. The goals of surgery for p...

PURPOSE. To measure the effect of void-filling calcium triphosphate cement on the loads at the implant-bone interface of a proximal humeral fracture osteosynthesis using a finite element analysis. METHODS. Finite element models of a 3-part proximal humeral fracture fixed with a plate with and without calcium triphosphate cement augmentation were generated from a quantitative computed tomography...

Proximal humeral fractures have been a topic of discussion in medical literature dating back as far as 3rd century BC. Today, these fractures are the most common type of humeral fractures and account for about 5-6% of all fractures in adults with the incidence rising rapidly with age. In broad terms the management of proximal humeral fractures can be divided into two categories: conservative ve...

Fractures of the proximal humerus can lead to malalignment of the humeral head, necrosis and post-traumatic osteoarthritis. In such cases surface replacement might be a promising option. A total of 28 shoulders with glenohumeral arthritis subsequent to a fracture underwent surface replacement arthroplasty of the humeral head in patients with a mean age of 60 years (35 to 83). On the basis of th...

Fracture of the proximal humerus associated with vascular injury has rarely been reported in children, and only two cases have been reported in the literature. In adults this combination has been reported more frequently. We present the case of a 14 year old boy with proximal humeral epiphyseal separation and axillary artery injury.

Background: Proximal humeral fracture-dislocations (PHFD) are a special entity in proximal humeral fracturetreatment. The aim of this study is to present our minimally invasive plate osteosynthesis (MIPO) technique throughan anterolateral deltoid split approach. In addition, we performed a retrospective cohort study analyzing the patientreported functional outcome and complica...
