OBJECTIVE To prospectively evaluate the results from a series of patients who underwent surgical treatment for rhizarthrosis using the technique of trapezium resection associated with interposition of yarn from the long abductor tendon of the thumb. METHODS From May to August 2005, ten patients underwent surgical treatment for rhizarthrosis. Patients with primary osteoarthrosis of the trapezi...

PURPOSE The motion path of the digits follows the path of an equiangular spiral in which a constant angle is formed by all radial vectors along the curve. This implies that the lengths of the metacarpals, proximal, middle, and distal phalanges approximate a Fibonacci sequence in which the ratio of any 2 consecutive numbers approaches the number 1.61803 (phi). This study tested the hypothesis th...

Introduction: Metacarpals and phalanges are injury prone in daily work and life. These constitute 10% of all fractures. Although these fractures are considered minor injuries, such injuries may cause major disabilities if not taken care of. Most hand fractures can be treated by nonoperative methods with good outcome. However unstable fractures need some form of fixation. Aim of our study is to ...

Acromegaly is a chronic progressive disease that originates from the increased secretion of the insulin-like growth-hormone (IGF-1) secondary to the hypersecretion of the growth hormone (GH). The enlargement of the minor hand and foot bones represents an early finding in this disease. Kleinberg et al. used the sesamoid index (SI) values for diagnosing the disease. The present trial was designed...

A retrospective study was conducted to evaluate the outcome of treatment with alendronate (ALN) for 5 years in postmenopausal Japanese women with an increased risk of fractures. Forty postmenopausal Japanese women with osteoporosis or osteopenia and clinical risk factors for fractures (mean age: 75.4 years) were analyzed; 33 patients were treated with alendronate and 7 were treated with alfacal...

as he was being conveyed by trolley from Toondla, where the accident happened, to Agra, a distance of about 15 miles. On removing innumerable cloths soaked in blood, I found that the thumb with its metacarpal bone had entirely disappeared. Ttie metacarpal bone of the index finger was, as it were, dissected out from the palm of the hand, completely denuded of flesh, and separated from the carpal...

Previous studies have shown a strong correspondence between long bone bilateral asymmetry and reported handedness. Here, we compare the pattern of asymmetry in mechanical properties of the humerus and second metacarpal of Pan troglodytes, recent British industrial and medieval populations, and a broad range of human hunter-gatherers, to test whether technological variation corresponds with late...

In nine patients of median age 34 years who had sustained an amputation of the thumb at a median 24 (5 to 131) months previously, we lengthened the first metacarpal by 30 (17 to 36) mm. Seven amputations had been through the proximal phalanx and two through the metacarpal. The first two patients had autogenous grafting at a second stage, but the other seven had callotasis alone. In these patien...

OBJECTIVE To compare changes in regional bone mineral density (BMD) of the metacarpal joints measured by dual x ray absorptiometry (DXA) and digital x ray radiogrammetry (DXR) in relation to disease activity and radiographic outcome in a two year follow up study of patients with early RA and unclassified polyarthritis. PATIENTS AND METHODS 72 patients with symmetrically swollen and tender sec...

OBJECTIVE To evaluate vertical forces in the pads of German Shepherd dogs by relative percentage among total limb vertical forces using a pressure sensitive walkway. PROCEDURE A pressure sensitive walkway was used to collect vertical force data for each pad of the limbs of 16 healthy client-owned German Shepherd dogs used for kinetic gait analysis. The vertical force for each pad was evaluate...
