In 148 children who had sustained trauma to the upper extremities from falls, fractures were twice as common on the left as on the right side. This seemed to be due to the childrens' preferential use of the left hand to parry the fall even when both hands were free and because the left arm seemed to be more easily broken than the right arm during trauma.

As the automobile has evolved over its first 100 years, many changes have improved its safety and have resulted in lower fatality rates. To a great extent, physicians have provided the thrust for these improvements. Now, as more people survive automobile accidents, injuries to the musculoskeletal system take on importance as causes of individual disability and social cost. The patterns of automobile-induced orthopedic injuries continue to change. This article reviews the first 100 years of these injury patterns and relates their occurrence to specific automobile design features and oversights. Because any one automobile accident is likely to injury only a few people at most, trends and patterns are much more difficult to ascertain than for mass transit vehicular accidents. For this reason, physician awareness of contemporary injury patterns is the first step toward safer automobile design.

Based on experiments on fresh cadaveric and accidentally amputated 8 upper limbs of children, study of ulnae for presence and absence of non articular strip on the trochlear notch, measurements of carrying angle, length of forearm bones, pronation-supination, height and weight in 2250 infants, children and adults of various age groups and clinical observations on 800 cases of injuries around elbow many new facts have been observed about the development of the carrying angle and its significance in the etiopathogenesis of various types of fractures seen around the elbow. The carrying angle develops in response to pronation of the forearm and is dependent on length of the forearm bones. Lesser the length of forearm bones greater is the carrying angle. So the carrying angle is more in shorter persons as compared to taller persons. It is abduction at the shoulder and not the carrying angle which keeps the swinging upper limbs away from the side of the pelvis during walking. Carrying angle is not a secondary sex character. The type of fracture a child sustains after fall on outstretched hand is also determined by the value of the carrying angle. A new type of fracture hitherto undescribed in the literature, T-Y fracture of the distal humeral epiphysis is also reported.
Supracondylar humerus fractures are the most common elbow injury in children. Stable fractures can be closed, reduced, and casted, whereas unstable fractures require percutaneous pinning. Studies have shown that there is a biomechanical advantage of crossed pin fixation as opposed to two lateral pin fixation. However, medial pin placement has the risk of injuring the ulnar nerve. This modification of technique was used on 46 patients, aged 12 months to 14 years (median age, 3.6 years). Two patients had an ulnar sensory and motor neurapraxia, and two patients had cubitus varus deformities postoperatively. Thus, a safe, easy, and reproducible technique of crossed pin fixation is described here.

The authors have dissected 20 forearms of human cadavers to study anatomy and some functions of the IOM. The fibers bundles of the IOM were arranged in one plane descending obliquely and distally from the radius to insertion to the ulna. Central band of the IOM was easily found and was thick. It's a resistant ligament for longitudinal stability of the radius. Now, it's important to know anatomical alignment of the IOM because ultrasound imaging can be used for diagnosis of its rupture or elbow injuries and in a early future, surgical methods of repair or reconstruction of IOM will be developed.

BACKGROUND: With current techniques of plate-and-screw fixation, diaphyseal nonunions of the radius and ulna are unusual. The few reports that have been published have discussed the use of structural corticocancellous bone grafts for the treatment of atrophic nonunions that are associated with osseous defects. We reviewed the rate of union and the functional results in association with the use of plate-and-screw fixation and autogenous cancellous (nonstructural) bone grafts. METHODS: Thirty-five patients with an atrophic ununited diaphyseal fracture of the forearm were treated with 3.5-mm plate-and-screw fixation and autogenous cancellous bone-grafting. A segmental osseous defect with an average size of 2.2 cm (range, 1 to 6 cm) was present in each patient. Twenty of the original fractures had been open. Eleven patients had had treatment of a deep infection before referral to us. The nonunion involved both forearm bones in eight patients, the radius alone in sixteen patients, and the ulna alone in eleven patients. RESULTS: The atrophic nonunion was associated with an open fracture in twenty patients, suboptimal fixation in twenty-two, a fracture-dislocation of the forearm in nine, and infection in eleven. All fractures healed without additional intervention within six months. Two patients had a subsequent Darrach resection of the distal part of the ulna for the treatment of arthrosis of the distal radioulnar joint. After an average duration of follow-up of forty-three months, the final arc of motion averaged 121 degrees in the forearm, 131 degrees at the elbow, and 137 degrees at the wrist, with an average grip strength of 83% compared with that of the contralateral limb. According to the system of Anderson and colleagues, five patients had an excellent result, eighteen had a satisfactory result, eleven had an unsatisfactory result (because of elbow stiffness related to associated elbow injuries in three and because of wrist stiffness in eight), and one had a poor result (because of malunion). CONCLUSIONS: When the soft-tissue envelope is compliant, has limited scar, and consists largely of healthy muscle with a good vascular supply, autogenous cancellous bone-grafting and stable internal plate fixation results in a high rate of union and improved upper limb function in patients with diaphyseal nonunion of the radius and/or ulna.

The authors describe a rare instance of elbow dislocation associated with Galeazzi fracture-dislocation in a 16 year-old patient injured in a motor vehicle accident. They analyze the modalities of the trauma, the type of treatment employed, and the result after 2 years.

Squash is a game which demands physical fitness: you should be fit to play squash, not play squash to get fit. GPs may expect to see eye injuries, tennis elbow, ankle injuries and Achilles tendon ruptures. A knowledge of the nature of the game can help in the management of the problem.
