Proximal humerus fractures are common and have a bimodal age distribution. Fracture-dislocations in younger patients result from highenergy trauma and most surgeons attempt open reduction and internal fixation, if at all possible. Osteoporotic fractures in elderly patients are commonly associated with low-energy trauma such as groundlevel falls and most are minimally displaced, impacted fractur...

INTRODUCTION Proximal humeral fractures account for 4% to 5% of all fractures. Complex proximal humeral fractures with displaced three- and four-part fragments, humeral head splits and fracture-dislocations are more difficult to treat. In older patients, because of poor bone quality, hemiarthroplasty is often the indicated treatment. CASE REPORT One such case of a 73-year-old woman is present...

We analyzed three-dimensional (3D) humeral deformity (valgus-varus, flexion-extension, and rotational deformation) after little leaguer's shoulder using 3D computed tomography in a 15-year-old male baseball player. Humeral retroversion was increased by 27.1° on the dominant side compared with the nondominant side. Compared with the nondominant shaft, the dominant humeral shaft was deformed in t...

High-energy trauma to the shoulder is associated with multiple injuries and is often difficult to evaluate. One of these complex traumas is the displacement of the humeral head into the thoracic cavity. This study aimed to report a patient who presented after falling three floors. Initially, the patient underwent chest drainage and thoracoscopy to remove the displaced humeral head and, subseque...

simultaneous dislocation of shoulder and humeral shaft fracture is a rare injury, and there is no clear protocol for its treatment. herein we present a case of a 15-year-old boy, who suffered from a job-related accident and sustained fracture of humeral shaft associated with ipsilateral anterior shoulder dislocation and fracture of greater tuberosity 15 years ago. he received closed reduction o...

BACKGROUND The main objective of this study is to describe a new surgical technique that, through a gleno-humeral approach, reduces the incongruent joint while a humeral head centering osteotomy achieves shoulder stabilization. A humeral medial derotational osteotomy is performed associated with the articular reduction. PATIENTS AND METHODS Fourteen patients with obstetrical palsy presenting ...

Distal humeral periprosthetic fractures below intramedullary nail devices are complex and challenging to treat, in particular due to the osteopenic/porotic nature of bone found in these patients. Fixation is often difficult to satisfactorily achieve around the intramedullary device, whilst minimising soft tissue disruption. Descriptions of such cases in the current literature are very rare. We ...

We studied the arterial anatomy and the effect of fourpart fractures on the vascularity of the humeral head, using barium sulphate perfusion of 16 cadaver shoulders. The main arterial supply to the humeral head was via the ascending branch of the anterior humeral circumflex artery and its intraosseous continuation, the arcuate artery. There were significant intraosseous anastomoses between the ...
