Forearm rotation affects grip strength. In a study with 40 volunteers, an overall decrease in grip strength was observed when the forearm rotated from pronation to supination. In males grip strength in pronation was significantly lower compared to the neutral and supinated position, with the wrist free as well as in an immobilized wrist position. In females… (More)
The aim of this study was to investigate the correlation between the severity of Dupuytren contracture and disability. The American Medical Association (AMA) guidelines were used to assess the impairment for each involved hand. The disability of the arm, shoulder and hand (DASH) questionnaire was used for evaluating the disability. Eighty patients with 102… (More)
The incidence of overuse syndromes of the elbow, wrist and hand was evaluated in a series of 66 pianists: 28 presented such a pathology. No significant correlation with starting age, or duration and intensity of practice was revealed. Smaller hands lead to more frequent overuse syndromes, in both males and females. Conditioning, sports activity, playing a… (More)
The DASH (Disability of Arm, Shoulder and Hand) score is being used increasingly as an outcome measure for upper limb pathology. In our clinical practice the DASH score has been used to study the outcome of several common upper limb disorders. We reviewed the literature and applied the principles of the World Health Organization on this scoring system.
The grip strength in a group of 487 healthy children aged between 5 years and 15 years was measured. There was a clear correlation between age and grip strength. Up to the age of 12 years, there was a striking parallellism between boys and girls. From the age of 13 years, boys developed a 25% stronger grip force than girls. The difference between the… (More)
The aim of this study was to identify possible anatomical risk factors for Kienbock's disease. We measured on a posteroanterior radiograph of the wrist, in zero-position, the Lunate Diameter and Height, Lunate Tilting Angle, Lunate Uncovering Index, Lunate Fossa Inclination, Radial Inclination and Ulnar Variance. We measured these seven parameters on the… (More)
A case of an older female patient with paralysis of the anterior interosseous nerve is reported. During exploration an accessory muscle slip running from the coronoid process of the ulna towards the flexor pollicis longus (Gantzer's muscle) was found compressing the nerve.
Closed traumatic avulsion of both extensor carpi radialis tendons is reported in a young healthy patient. Early diagnosis important because the tendons tend to retract and anatomic repositioning is more difficult to perform with passing time. Diagnostic markers are the inability to actively extend the wrist and the presence of dorsal bone fragments on the… (More)
Arthrodesis of the wrist has been considered as the gold standard for osteoarthritis of the wrist. In 1984 Watson and Ballet identified a specific pattern of carpal collapse (scapholunate advanced collapse = SLAC) with progressive osteoarthritis. In order to preserve some motion, other alternative procedures have been proposed: proximal row carpectomy (PRC)… (More)
In a prospective study the grip strength was measured preoperatively in 17 patients with chronic tennis elbow and postoperatively after a minimum follow-up of 1 year. The grip strength measured with a flexed and extended elbow was significantly less on the involved side (28.4 and 17.2 kg) than on the normal side (36.4 and 36.5 kg) ; postoperatively it… (More)
