“…The implants were loaded axially and at 30°, the latter representing the maximum excursion of the CMC joint from the neutral position (Kapandji, 1986). A motion capture study of thumb pinch (key pinch and tip pinch) showed that the CMC joint moves about half of this angle (12.9° for key pinch and 16° for tip inch) during the two types of pinch which are the situations where the thumb is maximally loaded in daily life (Jahn et al, 2013). Thus, one could argue that we should have used a smaller angle, but we do not think the exact angle is of great importance in this study.…”

“…We recognize that our unidirectional testing at a constant load of 50 N represents a simplification of the clinical situation where the load will vary in direction and magnitude. For many daily activities the load passing through the thumb will be low and higher loads will generally pass through a stabilized joint with little or no motion occurring during various forms of lateral or pulp pinch, as confirmed by Jahn et al in their video motion capture study (Jahn et al, 2013).…”

Metal-on-metal articulations have fallen out of favour in larger joint replacements, but are still used in smaller joints. Coating the articulation has been suggested as one way of reducing wear. We compared a standard 6 mm CrCoMo articulation designed for the carpometacarpal joint of the thumb with a chromium nitride-coated version after 512,000 cycles in a joint simulator. A total of 6 articulations in each group were tested with a unidirectional load of 5 kg in Ringer's solution. We found a statistically significant reduction in weight loss, amount of metallic wear produced and volumetric wear for the chromium nitride-coated articulation. Our findings support the use of chromium nitride coating in order to minimize the amount of metallic wear produced.

The human hand is a versatile organ that performs a variety of activities in daily life. The coordination of digits allows them to deal with objects of various sizes and shapes with an appropriate range of motions (ROM). A systematic literature review was performed to identify the clinical and non-clinical factors which affected the normal ROM, grip strength (GS), and dexterity of hand. The overall outcomes of the systematic review showed that: the performance of the individual declined as the age progressed; the performance of the dominant hand (DH) of an individual was better compared to his/her non-dominant hand (NDH); the tasks performed by a healthy hand was more efficient compared to a diseased one; appropriate rehabilitation programs/exercise techniques after a disease or injury improved the ROM, GS, and dexterity of hand post-surgery on par to a healthy hand.

Identification of Three Movement Phases of the Hand during Lateral and Pulp Pinches Using Video Motion Capture

Abstract: VMC is a feasible and valid method for objectively quantifying dynamic movement of multiple joints simultaneously. The results provide new insight to the dynamics of hand movement as well as a basis for subsequent evaluations of movement patterns performed in ADLs and instrumental ADLs.
