Proximal humerus fractures are among the most common fractures associated with osteoporosis. With an aging population, incidence of these fractures will only increase. The proximal humerus not only forms the lateral portion of the shoulder articulation but also has significant associations with musculoskeletal and neurovascular structures. As a result, fractures of the proximal humerus can sign...

In this case, a 31 year-old female was diagnosed of isolated fractures of lesser tuberosity humerus. The patient could take early functional training of shoulder joint two days after operation. Although isolated fractures of lesser tuberosity humerus are rare, when pain of anterior shoulder joint after trauma, doctors should consider isolated fractures of lesser tuberosity humerus. As for the t...

Humerus fracture is very rarely associated with ipsilateral shoulder dislocation. Here, we have reported probably the first case of compound fracture of humerus associated with a two-part fracture dislocation of ipsilateral shoulder. A 30-year-old female presented to the emergency department after a road traffic accident. The vehicle in which she was travelling skidded off the road and she got ...

In our daily life, accident would happen with arterial haemorrhage, and death would be brought out by continuous arterial bleeding for little time if emergency has not been implemented in time. This paper presents a humerus arterial bleeding simulation model (HABSM) for hemostasia, which has a high-fidelity, practical model for the humerus arterial hemostasia operation that is not only for the ...

INTRODUCTION Distal humerus is a very rare predilection site of osteosarcoma. Limb salvage surgery has widely replaced amputation for surgical treatment of most types of malignant bone sarcomas. PRESENTATION OF CASE We presented a 42 years old male with rapidly growing osteosarcoma on his right distal humerus. After induction chemotherapy, wide excision and reconstruction using free vasculari...

Axillary artery injury associated with proximal humerus fractures was rare clinically, which exhibited varying clinical manifestations. In this study, an 80-year-old woman suffered from axillary artery injury secondary to proximal humerus fracture was presented. This case exhibited large ecchymosis in the left upper limb and chest skin. A left 4-part proximal humerus fracture dislocation inferi...

Proximal humerus fractures are common, but associated injury of the axillary artery is uncommon. The majority of published blunt traumatic axillary artery injuries are associated with anterior glenohumeral dislocation; a few are associated with isolated proximal humerus fractures or fracture-dislocation. Experience within our institution demonstrates that axillary artery injury is often unrecog...

UNLABELLED Describe the results of proximal humeral fractures surgically treated with the Philos locking plate system. METHOD Between March 2003 and October 2004 we prospectively reviewed 24 of 26 patients with proximal humerus fractures treated with a Philos plate. The mean follow-up time was 12 months and the mean age of patients was 57 years. Six patients had four-part proximal humerus fra...

The purpose of this research is to test the experimental conditions which lead to the best determination of the glenohumeral joint rotation centre in vivo with two shoulder circumductions (30°,130° abduction) and two relative displacements (humerus with respect to scapula or clavicle). Nine subjects perform circumduction movements of small magnitude. Three functional methods were used to estima...

BACKGROUND The substantial increase in the utilization of shoulder arthroplasty in the United States during the past decade is partly attributable to the growing acceptance of reverse shoulder arthroplasty (RSA). This study compared the national utilization of and indications for shoulder hemiarthroplasty, total shoulder arthroplasty (TSA), and RSA. METHODS The Nationwide Inpatient Sample was...
