Abstract Aim Fragility hip fracture is associated with significant morbidity and mortality. Bone biomechanics are central to orthopaedic surgery as it vital optimise patient outcomes. This review aims provide the relevant of for clinicians. Method The following terms were used in Embase Medline: biomechanics, fracture, proximal femoral fragility fracture. Bibliographies articles scrutinised ide...

Case Description-An adult golden eagle with a wound on its right wing caused by gunshot was presented to the University of Tabriz, Veterinary Teaching Hospital. Clinical Finding-Clinical examination and radiographs, revealed compound fracture in distal third of humerus, severe soft tissue compromise and irreparable loss of blood supply. Anemia and leukocy...

We study a lattice model for mode III crack propagation in brittle materials in a stripe geometry at constant applied stretching. Stiffening of the material at large deformation produces supersonic crack propagation. For large stretching the propagation is guided by well-developed soliton waves. For low stretching, the crack-tip velocity has a universal dependence on stretching that can be obta...

Sleeve fractures of the upper pole of the patella in children are rare; only 2 cases have been reported in the English literature and 1 case in the German literature. We present a case of this unusual lesion in order to stress the importance of being aware of the existence of upper pole sleeve fractures of the patella. We review the literature and we describe the symptoms, the clinical and radi...

PURPOSE. To report the outcomes of Polarus nail fixation for displaced proximal humeral fractures. METHODS. Medical records of 19 men and 27 women aged 26 to 84 (mean, 63) years who underwent fixation using a standard Polarus nail (n=34) or Polarus plus nail with shaft extension (n=12) for proximal humeral fractures of 2 and 3 parts (n=34) and 2-part with extension to the shaft (n=12) were revi...

BACKGROUND Proximal humeral fractures are common osteoporotic fractures. Most proximal humeral fractures are treated non-surgically, although surgical treatment has gained popularity. The purpose of this study was to determine changes in the surgical treatment of proximal humeral fractures in Finland between 1987 and 2009. METHODS The study covered the entire adult (>19 y) population in Finla...

Yoshida N, Tsuchida Y. BMJ Case Rep 2017. doi:10.1136/bcr-2017-222303 Description A 9-year-old boy presented to the emergency department with severe left elbow pain after a fall from a skateboard. On physical examination, an open injury in his left elbow that exposed the humeral lateral epicondyle was observed (Gustilo grade; figure 1A). The radial pulse was well palpated, but the neurological ...

Proximal humeral fractures are complex lesions with difficult management problems; therefore, they pose a challenge for orthopaedic surgeons. In the literature, numerous treatment techniques have been proposed for these kinds of fractures. In our study we reviewed 30 patients with a mean age of 75 years presenting a proximal humeral fracture (Neer 2-3) and treated at our clinic with a Polarus n...
