Uniaxial quasi-static, uniaxial dynamic and confined dynamic compression experiments have been performed to characterize the failure and deformation mechanisms of a sintered polycrystalline aluminum nitride using a servohydraulic machine and a modified Kolsky bar. Scanning electron microscopy and transmission electron microscopy (TEM) are used to identify the fracture and deformation mechanisms...

Objective: The study aims to explore the clinical effect of open reduction surgery for anterior dislocation of the shoulder combined with surgical neck fracture of humerus of badminton athletes. Methods: Clinical data of 2000 patients with anterior dislocation of the shoulder combined with surgical neck fracture of humerus admitted in our hospital from June 2012 to June 2014 were analyzed retro...

carpal injuries are uncommon and are mainly seen in the younger age group. the incidence is unclear as many of the cases go undiagnosed. a 22-year-old male patient coming to the hospital after road traffic accident with head, face and left wrist injury. after immediate primary management the patient was taken up for a definitive procedure 4 days after the injury. scaphoid fracture was fixed wit...

INTRODUCTION Traumatic anterior dislocation of the shoulder is an emergency and warrants urgent attention. However, it becomes difficult to manage in cases of associated fractures of humerus and other bones surrounding the shoulder joint. There have been reports of traumatic anterior dislocation of the shoulder associated with humeral fractures in the literature but the trilogy of anterior disl...

The relationship between the bone mineral density (BMD) and Charcot arthropathy is unclear. Prospectively, 55 consecutive diabetic patients presenting with a Charcot arthropathy of the foot or ankle were classified as having a fracture, dislocation, or a combination fracture-dislocation pattern of initial destruction. In these groups we used dual-energy x-ray absorptiometry to compare the perip...

INTRODUCTION Injuries causing fracture dislocation of shoulder and brachial plexus palsy are extremely rare. As per authors' knowledge, three part fracture of proximal humerus with shoulder dislocation and brachial plexus palsy has not been reported in the literature. CASE PRESENTATION A 53 year old female sustained a three part fracture of right proximal humerus along with dislocation of sho...

Traumatic dislocation of the head of the radius in children may be either an isolated injury or, more commonly, part of a more complex injury to the elbow, such as the Monteggia fracture-dislocation. in that injury the dislocation of the head of the radius is described as anterior or posterior and the fracture of the ulna affects its shaft (Watson-Jones 1956). Wise (1941) reported a case of lat...

Simultaneous bilateral posterior dislocation of the shoulder complicated with a fracture (fracture-dislocation) is an extremely rare condition and the relevant literature contains very few published case reports. Besides its rarity, this complicated condition may cause delays in diagnosis because of the physicians’ tendency to use plain radiography which is known to have low sensitivity in dete...

INTRODUCTION Periprosthetic fractures and dislocation in the early post-operative period can be disastrous both for the surgeon and the patient. However, undisplaced periprosthetic fractures presenting with dislocation is uncommon. We describe successful management of two cases (one bilateral dislocation and one unilateral dislocation) of undisplaced iatrogenic fractures in total hip arthroplas...

A 50-year-old man, right-handed farmer, was admitted to the emergency department after undergoing an agriculture accident. Physical examination on admission revealed a left wrist disarticulation with a deformity of the ipsilateral elbow and forearm (A and B). Plain radiography showed a fracture of the ulna shaft as well as dislocation of the radial head. This radiological finding, also called M...
