Abstract Laxity of the anterior oblique ligament (AOL) and/or the dorsoradial ligament (DRL) are believed to contribute to the progression of osteoarthritis in the trapeziometacarpal joint through increased dorsal subluxation. Stress radiographs during functional tasks, such as key pinch, can be used to evaluate such joint instability. Cadaveric experiments can explore joint contact pressures as well as subluxation under varying conditions, to gain knowledge about joint mechanics. The disturbance of supporting tissues, such as the joint capsule, during experiments may affect the recorded stability of the joint. To evaluate potential effects of opening the joint capsule and severing the AOL, eleven cadaveric specimens were rigged to simulate key pinch. An anteroposterior (AP) radiograph of the hand was recorded for each specimen while intact, after partially opening the joint capsule and after sectioning the AOL. First metacarpal subluxation levels were compared between the intact joint, partially open joint capsule, and sectioned AOL. Neither opening the joint capsule nor cutting the AOL had a statistically significant effect on metacarpal subluxation. The results indicate that partially opening the joint capsule has a negligible effect on joint mechanics and support recent studies that postulate that the AOL plays a less substantial role in preventing subluxation.

Anterior Oblique Ligament

An anatomical and biomechanical study of the stabilizing ligaments of the thumb trapeziometacarpal joint was conducted on 32 hand specimens. Five main ligamentous structures could be identified. The mechanical properties (in particular, strength) of the five ligaments using a strain-rate failure test were determined and evaluated quantitatively. The maximum tensile strength of each ligament was correlated with the condition of the trapeziometacarpal articular cartilage. In studying the anterior oblique ligament, maximum strength decreased from Grade 0 to Grade 1 by 51%. With the first intermetacarpal ligament, the drop from Grade 1 to Grade 2 was 53%. With the posterior oblique ligament, the decrease was closely related to the grade of the deterioration of the trapeziometacarpal articular surface. These three ligaments also significantly decreased in strength with age. Our results may suggest that the anterior oblique ligament, intermetacarpal ligament and posterior oblique ligament play a large role in stabilizing the trapeziometacarpal joint and that the decrease in their strength is related to the pathogenesis of trapeziometacarpal osteoarthritis.

AbstractThe first carpometacarpal (CMC) joint consists of seven ligaments. The magnetic resonance imaging (MRI) examination of the first CMC joint should be performed in a high field 1.5/3 T MRI with a dedicated hand coil for high-resolution images. Degeneration of anterior oblique ligament (AOL) is the most important cause for the development of osteoarthritis of first CMC joint. Since the AOL undergoes a predictable pattern of alteration at its metacarpal attachment as degeneration proceeds, MRI imaging can provide an accurate assessment of this ligament.

Introduction: Trapezium fracture is a rare entity whose treatment is controversial. The reported cases range from conservative treatment to surgical treatment with good reported results. Case Report: This paper reports a clinical case of trapezium-metacarpal fracture-dislocation associated with trapezius fracture and Bennett fracture, surgically treated with excellent functional and radiological results. The patient underwent open reduction and internal fixation with two screws, excision of fragments, and reinsertion of the anterior oblique ligament. At the year of follow-up, the patient presented no mobility limitations and recovered grip strength. Conclusion: This case study allows us to conclude that open reduction and internal fixation with screws of the dorsal trapezium ridge fractures with ligament repair of the anterior oblique ligament is a valid treatment with the reproduction of good clinical results. Keywords: Hand surgery, internal fixation, trapezium fracture.
