Thumb Carpometacarpal

Diagnostic and rehabilitative assessments of hand function commonly omit measurement of twisting strength even though many activities of daily living require turning handles, lids, and objects of many sizes. A simple device to quantify twisting strength was designed and constructed to establish normative data and test hypotheses about hand function. The instrument is easy to use and includes an electronic torsional load cell and disks of several sizes. Tests were conducted on the dominant and nondominant hands of 64 normal subjects and 13 arthritic patients with arthritis of the thumb carpometacarpal joint. Hands were tested with disks ranging in diameter from 2.5to12.5cm. A three-way repeated measures analysis showed that gender (p<0.001), handedness (p<0.001), and disk size (p<0.001) had significant effects. There was no difference between radial and ulnar deviation strengths (p=0.365). The arthritic group had significantly reduced strength (p<0.02). Nine subjects were tested twice, with 1day between tests: no differences occurred between the first and second testing (p=0.930). The ability to distinguish the test groups with reproducible results proves that the device fulfills all basic requirements; continued testing and development are warranted.

Cmc Joint

Osteoarthritis (OA) of the human thumb carpometacarpal (CMC) joint is a debilitating disease. It has been proposed in the clinical literature that joint ligamentous laxity, or joint looseness, is a major etiological factor in OA of the CMC joint (Figure1) [1–4]. Previous investigations of laxity and stability of the human thumb CMC joint have been performed visually, with no quantitative measures of joint laxity recorded [5–7]. Surgical treatment has been a common solution to reduce the pain associated with CMC OA. One treatment, extension osteotomy of the 1st metacarpal, has been suggested not only to reduce the pain of OA, but also improve hand function [8], however, little is known about its biomechanical effects. A complete description of joint laxity requires that all physiological directions of motion be fully tested. A custom-designed, 4 degree of freedom tester was constructed and instrumented for displacement and load in the distraction-compression, dorsal-volar, pronation-supination, and radial-ulnar directions. The purpose of this study was to use this device to: 1) Measure the joint laxity and compliance of non-OA human thumb CMC joints and 2) Determine the effect that a simulated extension osteotomy has on joint laxity and joint stiffness. This study provides an accurate baseline for future comparisons with osteoarthritic, surgically corrected, and otherwise non-healthy CMC joints.

This review describes the different possibilities for arthroplasties at the proximal interphalangeal joint, thumb carpometacarpal joint, distal radioulnar joint, metacarpophalangeal joint and the wrist. For each joint, the indication for arthroplasty is explained, the surgical technique with the suitable implant is described and a brief summary of the outcomes reported in the literature is given.

Background and aim: Patients with mild to moderate first carpometacarpal joint osteoarthritis report pain, a reduction in pinch and grip strength and hand function. The purpose of this study was to analyze the effect of a custom-made neoprene thumb carpometacarpal orthosis with thermoplastic stabilization on pain, function, grip strength, and key pinch in these patients. Technique: A total of 11 volunteer patients participated in this study. All the above-mentioned parameters were evaluated at baseline and also 30, 60, and 90 days after using the splint. Discussion: A decrease in pain was observed after 30 days, and this continued to improve during treatment with the splint. After 90 days of using the splint, grip strength was improved. Function and pinch strength also increased significantly and was maintained during the study period compared to baseline. Clinical relevance A custom-made neoprene thumb carpometacarpal orthosis with thermoplastic stabilization may be a suitable conservative approach for the treatment of first carpometacarpal joint osteoarthritis.

And Function

Background: Pellegrini’s surgical technique is the most useful for thumb carpometacarpal joint osteoarthritis. The purpose of this paper is to describe the technique of a modified version using a bone block in the tunnel through which the flexor carpi radialis tendon is passed (BBTI). Methods: Case series of patients diagnosed with osteoarthritis of the thumb carpometacarpal joint, in stage II or higher based on Eaton’s classification, that were intervened using the BBTI technique for a 2-year period. Grip and pinch strength, range of motion, and 1–2 metacarpal angle were evaluated. Pain and function were measured using the visual analogue scale and the Disabilities of the Arm, Shoulder and Hand (DASH) scale. Results: The study included 16 cases in 14 patients (11 women and 3 men), with an average age of 55.7 ± 7.1 years. Encouraging results were obtained, with an average DASH score of 24.3 ± 17.9 and a minimum VAS pain score. A total of 58% showed a grip strength of over 80% and the postoperative movement was equivalent to the contralateral limb. No cases of infection were reported, and only two minor complications were observed. Conclusions: The BBTI technique is a surgical option that incorporates an interference screw, offering good functional results for managing osteoarthritis of the thumb carpometacarpal joint, with a similar complication rate to that of the original technique.
