Fractures of the articular surface of the distal end of the humerus (i.e., of the capitellum and the trochlea) are rather uncommon injuries. Fractures of the capitellum account for 1% of all elbow fractures and about 6% of all distal humeral fractures. Fractures of the trochlea are usually encountered as part of more complex intra-articular fractures of the distal end of the humerus, disrupting...

BACKGROUND The incidence of shoulder joint dislocation has been estimated at 11-26 per 100 000 population per year. In our opinion, basic epidemiological data need to be continually updated in studies of large populations. To study the incidence of posttraumatic dislocation of the shoulder joint in the Polish population. MATERIAL AND METHODS We retrospectively investigated the entire Polish pop...

The management of acromioclavicular joint separations, in particular Rockwood types III and V, remains controversial. The purpose of this study was to investigate the observer reliability of shoulder surgeons when presented with the same cases of acromioclavicular joint separations. The authors retrospectively identified 28 patients who were diagnosed with a type III, IV, or V acromioclavicular...

Widespread use of gait or motion analysis in the diagnosis of patients with locomotor pathology and the subsequent planning and assessment of treatment has been limited because of its reliability, particularly in evaluating frontal and transverse plane components. This is because spatial reconstruction of the musculoskeletal system and calculation of its kinematics and kinetics via a skin marke...

The shoulder joint has the greatest range of motion of any joint in the body. However, it relies on soft-tissue restraints, including the capsule, ligaments, and musculature, for stability. Therefore, this joint is at the highest risk for dislocation. Thorough knowledge of the shoulder's anatomy as well as classification of dislocations, anesthetic techniques, and reduction maneuvers is crucial...

Volar dislocation of the carpometacarpal joint of the little finger is an uncommon injury. It is subdivided in ulnopalmar and radiopalmar dislocations. The injury can easily be missed on standard x-rays. Closed reduction and K-wire fixation has commonly been used in the treatment, although closed reduction and casting has been reported. Only 10 cases of an ulnopalmar dislocation were published ...

. Historically, 96% of shoulder dislocations have been attributed to a traumatic episode with anterior dislocation accounting for 97% of these. . Traumatic dislocation of the glenohumeral joint is the most common joint dislocation with an incidence of 8.2 to 23.9 per 100,000 per year. The male to female ratio is 2.55: 1 with almost 50% occurring in patients between the age of 15 years and 29 ye...
