AI Article Synopsis

  • There are several surgical methods to treat thumb carpometacarpal (CMC) arthritis, but the exact cause of the condition is still not fully understood.
  • Understanding the thumb CMC joint involves examining its biomechanics, hormonal influences, and evolutionary development, as well as the impact of factors like sex and age on joint health.
  • New minimally invasive surgical techniques are emerging as alternatives to traditional ligament reconstruction methods for treating CMC arthritis.

Article Abstract

Although there are many surgical options to treat thumb carpometacarpal (CMC) arthritis, a precise etiology for this common disorder remains obscure. To better understand the physiology of the thumb CMC joint and treat pathology, it is helpful to examine the biomechanics, hormonal influences, and available surgical treatment options, along with the evolutionary roots of the thumb; its form and function, its functional demands; and the role of supporting ligaments based on their location, stability, and ultrastructure. It is important to appreciate the micromotion of a saddle joint and the role that sex, age, and reproductive hormones play in influencing laxity and joint disease. Minimally invasive surgery is now challenging prevailing treatment principles of ligament reconstruction and plays a role in thumb CMC joint procedures.

[Pain around the first ray of the hand: differential diagnoses and treatment].

Orthopadie (Heidelb)

January 2025

Klinik für Handchirurgie und Orthopädie, Spital Langenthal, Spital Region Oberaargau SRO AG, Langenthal, Schweiz.

Pain around the first ray of the hand, particularly in the thumb area, is a frequent clinical problem that can have various causes. This article explores the most important differential diagnoses, including thumb carpometacarpal (CMC-I) osteoarthritis (rhizarthrosis), de Quervain's stenosing tenosynovitis, carpal tunnel syndrome and Wartenberg's syndrome. A detailed medical history, targeted clinical examination and if necessary the use of modern imaging techniques are crucial for making the diagnosis.

Background: The outcomes of simple trapeziectomy (T) versus trapeziectomy with ligament reconstruction and tendon interposition (LRTI) for trapeziometacarpal (TMC) osteoarthritis have been compared in several systematic reviews (SRs) with conflicting results across the various outcomes studied. Despite a lack of conclusions regarding the superiority of one treatment versus the other, LRTI remains the most popular surgical option. This raises the questions of whether published SRs are of high methodological quality, and whether discordant conclusions can be attributed to differences in methodologic quality.

: For many years, advancements in hand joint replacement (JR) were relatively minor compared to those for large joints. However, the caution previously exercised due to high complication rates is gradually being replaced by the expanding use of JR therapies for small joints in the hand. Despite this progress, there is a lack of comprehensive data on the outcomes of hand JR and on the optimal infrastructure required to meet the growing demand for these therapies.
