Purpose: To assess the normal degree of laxity of the collateral ligaments (CLs) of the finger metacarpophalangeal (MCP) joints and to compare side-to-side differences in CL laxity.
Methods: One hundred subjects had measurements of the degree of laxity in the radial (RCL) and ulnar (UCL) collateral ligaments of the MCP joints of each digit on both hands with the joints at neutral and at 30° and 90° of flexion using a custom-made measuring device. Statistical analysis was performed to assess both the difference in laxity for each ligament at each position of flexion and between sides for analogous ligaments (eg, the right index RCL at neutral compared to the left index RCL at neutral).
Results: There was a significant decrease in laxity for all ligaments between neutral (mean, 24° laxity) and 90° of flexion (mean, 15° laxity). There was a side-to-side difference between the RCL of all digits in extension (mean, 3°) and the index RCL in flexion (2°). These differences were statistically significant but clinically minimal. There were no side-to-side differences between any of the other ligaments at any position.
Conclusions: Finger MCP joint CL stability increases with increasing flexion of the joint. There is little to no difference between analogous ligaments on either hand of the subject when tested in the same position of MCP joint flexion. Knowledge of the average degree of MCP joint CL laxity can be helpful in assessing a potentially injured joint. A patient's contralateral, uninjured side can be used to determine that individual's normal laxity and a substantial increase from this on an injured digit can indicate CL rupture.

This article introduces a surgical technique for cross-intrinsic transfers (CIT) to correct ulnar drift in rheumatoid hands performed under wide-awake local anesthesia no tourniquet (WALANT). This approach allows real-time adjustment of tendon transfer tension and active patient participation in hand movements and deformity correction during the procedure. It can be combined with other surgeries such as prosthetic replacement arthroplasties of the MCP joints.

The excessive proliferation of fibroblast-like synoviocytes (FLS) leads to synovial hyperplasia, a key pathological hallmark of rheumatoid arthritis (RA). Eupalinolide B (EB), a sesquiterpene lactone of Eupatorium lindleyanum DC., has anti-inflammatory effects and anti-proliferative activity in tumor cells.

: 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.

Background: Dupuytren's disease (DD) is a systemic connective tissue disorder of the palm, predominantly affecting men of Northern European or Caucasian origin over 55. In addition to conventional surgery, Dupuytren's contracture can be treated in a minimally invasive way by injecting bacterial collagenase into the cord. However, studies on the long-term success rate when compared to the gold standard, surgical limited fasciectomy, are limited.
