The results of excision of the distal ulna in 34 wrists of 25 patients with chronic rheumatoid arthritis of the distal radio-ulnar joint were reviewed. Rest pain had been cured or relieved in 77%, pain on pronation-supination in 86%, and limitation of pronation-supination in 90%, while 88% of the patients graded the result as excellent or fair. Despite this marked relief of symptoms, function o...
The parachutist injured in a dramatic accident often describes the injury in an incomplete and biased way and evaluation of materials based solely upon subjective information of this kind can be misleading and of no value for recommendations. As the relation between the mechanical factors of the injury and the lesion in ankle fractures is well documented, an investigation of clinical, radiologi...
OBJECTIVE To evaluate the frequency of deltoid ligament injury in bimalleolar supination-external rotation type fractures and whether there is a correlation between the size of the fractured medial malleolus and deltoid ligament injury . METHODS Twenty six consecutive patients underwent magnetic resonance exams after clinical and radiographic diagnosis of bimalleolar supination-external rotat...
The functional anatomy of the distal radioulnar joint was studied in relation to the whole forearm, using three fresh-frozen, above-elbow amputation specimens. The specimens demonstrate how the proximal and distal radioulnar joints together form a bicondylar joint of special character. The proximal "condyle," the radial head, rotates axially, whereas the distal "condyle," the ulnar head, is fix...
The authors report a rare case of the bilateral floating forearm in a 25year-old man , who presented the combination of injuries after a fall from third floor; The bilateral dislocation of the elbow and fracture –dislocation of two wrists .The elbows were reduced orthopedically and the right wrist was treated with external fixator and pinning in the left wrist. At twelve months the patient only...
Objective To evaluate the postoperative results of patients with supination-external rotation ankle fractures who underwent syndesmotic screw (SS) removal. Methods Retrospective cohort study assessing the late postoperative results of 35 patients operated from January 2013 to June 2015. Patients undergoing treatment of rupture of the distal tibiofibular syndesmosis with SS fixation and who di...
Traumatic hypersupination injury of the distal radioulnar joint is a rare injury, and occurs when sufficient supination force is applied to the joint so as to tear the volar radioulnar ligament, resulting in separation of the triangular fibrocartilage complex, and subluxation of the tendon of extensor carpi ulnaris. This allows the distal ulna to rotate such that the ulnar styloid comes to lie ...
A pronation deformity of the forearm following an obstetric brachial plexus injury causes functional and cosmetic disability. We evaluated the results of pronator teres transfer to correct their deformity in 14 children treated over a period of four years. The mean age at surgery was 7.6 years (5 to 15). The indication for surgery in each case was impairment of active supination in a forearm th...
This paper investigates the temporal control of a fast wing rotation in flies, the ventral flip, which occurs during the transition from downstroke to upstroke. Tethered flying Drosophila actively modulate the timing of these rapid supinations during yaw responses evoked by an oscillating visual stimulus. The time difference between the two wings is controlled such that the wing on the outside ...
