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 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 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.
Neurofibromatosis type 1 (NF1) is a common disorder that arises secondary to mutations in the tumor suppressor gene NF1. Glomus tumors are small, benign but painful tumors that originate from the glomus body, a thermoregulatory shunt concentrated in the fingers and toes. We report 11 individuals with NF1 who harbored 20 glomus tumors of the fingers and 1 in(More)
We measured the grip force in 20 chronic tennis elbows: The grip strength, measured with the elbow in 90 degrees flexion as well as in full extension, was significantly less (p < 0.001) on the pathological side when compared to the other, uninvolved side. on the pathological side, the grip strength measured with the elbow in full extension, was(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 glomus tumour of the finger is a benign tumour that develops from the neuromyoarterial elements of the glomus body, which is a specialised arteriovenous anas-tomosis involved in thermoregulation. In this structure the arterioles that connect with venules have a thick layer of concentrically arranged epitheloid smooth muscle cells. Contraction of the layer(More)
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)
