Surgical treatment of 3- and 4-part proximal humeral fractures remains challenging. This study retrospectively evaluated functional outcomes of locked plate fixation vs hemi-arthroplasty in 57 patients with 3- and 4-part proximal humerus fractures from 2003 to 2005 with a mean follow-up time of 35 months (range, 15.7-52.7 months). Mean patient age was 56.9 years (range, 29-81.7 years) for the o...

During a total shoulder replacement the glenohumeral joint is substituted by a prosthesis. The joint is a loose ball-and-socket joint, in which the humeral head is the ball and the glenoid is the socket. Most important for successful surgery is that the position of the center of rotation of the glenohumeral joint is maintained [1]. During motion, the two geometric centers of both spherical arti...

OBJECTIVE The objective of the present study was to develop a numerical model of the shoulder able to quantify the influence of the shape of the humeral head on the stress distribution in the scapula. The subsequent objective was to apply the model to the comparison of the biomechanics of a normal shoulder (free of pathologies) and an osteoarthritic shoulder presenting primary degenerative dise...

PURPOSE This study aimed to review the current state of the techniques and materials used to rehabilitate maxillofacial defects. MATERIALS AND METHODS The MEDLINE and EMBASE databases were searched for articles pertinent to maxillofacial prostheses published from January 1990 to July 2011. The main clinical stages were the subject of analysis. RESULTS A multidisciplinary approach is preferr...

The rotator cuff is often severely damaged in arthritis of the shoulder and there is no satisfactory technique for its repair. patients with a ruptured cuff and an eroded glenohumeral joint may have intractable pain, and standard methods of joint replacement are then inappropriate. A ball and socket prosthesis has been designed to replace the function of both the rotator cuff and the glenohumer...

results overall, there were 2 (2.7%) mason ii fractures, 21 (28%) mason iii fractures, and 52 (69.3%) mason iv fractures. arbeitsgemeinschaft fur osteosynthesefragen (ao) classification was also determined. of the 85 patients in our study, 75 were available for follow-up. follow-up averaged 41.5 months (range, 4 - 93 months). average scores for the cohort were as follows: morrey, 85.7 (median 9...

Four-part fractures of the upper end of the humerus are uncommon injuries and there is still dispute about the best form of management. A retrospective study of 32 patients with these injuries has shown that non-operative management is frequently followed by persistent pain, stiffness and dysfunction of the shoulder. A prospective study of 49 patients with this injury presenting at the Bristol ...

The literature on major upper limb replantation, especially those proximal to the elbow, is inadequate. An 18-year-old man presented to us with a left forequarter amputation. A replantation was attempted with a view to salvaging function and avoiding prosthesis. The procedure was technically challenging with a number of issues not highlighted in previous reports, particularly bony stabilization...

BACKGROUND Patients suffering from a pathological fracture or painful bony lesion because of metastatic bone disease often benefit from a total joint replacement. However, these are large operations in patients who are often weak. We examined the patient survival and complication rates after total joint replacement as the treatment for bone metastasis or hematological diseases of the extremitie...
