Despite the highly constrained nature of the elbow joint, dislocation is not uncommon. Uncomplicated (simple) dislocations are those that occur without fracture and usually can be managed successfully with closed reduction and early motion. Precise attention, however, should be given to the stability of the elbow immediately after reduction. Instability can persist in full extension and require...

The patient at the age of 34 and 150kg of body weight suffered left hip posterior dislocation with femoral head fracture in car crash accident. The patient had been admitted to hospital after midnight. The mechanism of injury goes as follows: axial force and flexion in the hip caused by impact of the car. The left leg clinically observed is in painful extension, with minimal movement, strong pa...

Mineralized tissues, such as bone and tooth dentin, serve as structural materials in the human body and, as such, have evolved to resist fracture. In assessing their quantitative fracture resistance or toughness, it is important to distinguish between intrinsic toughening mechanisms, which function ahead of the crack tip, such as plasticity in metals, and extrinsic mechanisms, which function pr...

The purpose of this case report is to describe the clinical presentation of a patient who suffered from a fracture of the lateral tubercle of the posterior talar process caused by a fall while rock-climbing. The initial evaluation revealed diffuse ankle swelling, tenderness, and pain at the distal aspect of both malleoli. Plain film radiography revealed a fracture of the posterior process of th...

PURPOSE To assess the results of treatment for flexion-type supracondylar humeral fracture in children. METHODS The treatment of 14 children with flexion-type supracondylar humeral fracture was reviewed. Severity was classified according to the Gartland system for extension-type fractures. Type-I fractures were treated with immobilisation in an extension cast. For type-II and -III fractures, ...

The present study investigates the failure mechanisms of industrial fiber materials, using a custom designed fiber cutting performance test bench. The fracture morphologies of single PA6 fibers are examined by scanning electron microscopy. The analysis reveals that fiber cutting can be distinguished according to four distinct stages of fiber failure represented by shearing, cutting, brittle fra...

Diaphyseal fractures of the metacarpals and phalanges are common injuries that can lead to impairment of hand function. The fracture pattern and soft-tissue injury vary with the mechanism of injury. The imbalance of the flexor and extensor forces created by displaced fractures will often produce a secondary angulatory deformity. Nonoperative treatment is indicated for reducible and stable fract...
