Summary
This study details a rare volar dislocation of four carpometacarpals without fractures. Open reduction and pinning led to complete recovery within six months, with no complications or residual pain.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- Carpometacarpal (CMC) joint dislocations are uncommon hand injuries.
- Volar dislocations of multiple CMC joints, particularly without associated fractures, represent an exceptionally rare subset.
Observation:
- A case of volar dislocation involving all four ulnar carpometacarpal joints is presented.
- The injury was characterized by the absence of any associated fractures.
Findings:
- Treatment involved open reduction and carpometacarpal pinning, guided by intraoperative stability.
- The patient experienced a complete recovery with full pain relief, strength, and mobility by the six-month follow-up.
- No surgical or post-operative complications were observed.
Implications:
- Open reduction and internal fixation (ORIF) of CMC joints can achieve excellent outcomes in rare dislocations.
- Tailoring surgical fixation based on intraoperative stability may minimize invasiveness, reduce joint stiffness, and prevent chronic pain.
- This case highlights the potential for successful non-operative management of multiple CMC joint dislocations with appropriate surgical intervention.

01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:09Bones 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.
The radius has a nail-shaped head, and a short...

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
