Summary
The Sauvé-Kapandji procedure improved pain and wrist rotation in rheumatoid arthritis patients. While it didn't fully prevent carpal collapse, it protected against ulnar shift, with midcarpal laxity being a key risk factor.
Area of Science:
- Orthopedic Surgery
- Rheumatology
- Radiology
Background:
- Rheumatoid arthritis commonly affects the wrist, leading to pain and instability.
- The Sauvé-Kapandji procedure is utilized for treating wrist instability in rheumatoid arthritis.
- Evaluating radiographic changes post-procedure is crucial for understanding its efficacy.
Observation:
- This study analyzed 43 rheumatoid wrists in 37 patients undergoing the Sauvé-Kapandji procedure.
- Patients exhibited preoperative vertical laxity in the radiocarpal and midcarpal joints.
- Clinical outcomes included pain reduction and improved forearm rotation.
Findings:
- The Sauvé-Kapandji procedure significantly reduced carpal collapse ratio and improved wrist rotation.
- Midcarpal joint vertical laxity was identified as a risk factor for postoperative carpal collapse.
- The procedure demonstrated a protective effect against ulnar carpal shift.
Implications:
- The Sauvé-Kapandji procedure offers benefits for pain and rotation in rheumatoid wrists.
- Preoperative assessment of midcarpal joint laxity is important for predicting outcomes.
- Further research may explore modifications to enhance carpal collapse prevention.

Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

Assessment of radial pulse
Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
