Post-traumatic carpal instability

Traumatic Carpal Axial Instability in a Professional Football Player

This is a case of traumatic carpal axial instability in a professional football player. Traumatic carpal axial instability characteristically involves longitudinal separation of the ulnar or radial distal carpal row along with intermetacarpal injury. Rarely, pancarpal ligament disruption occurs, as in this case. Early diagnosis and treatment of unstable wrist injuries is important in achieving ...

Post traumatic ligamentous instability of the wrist.

Dorsiflexion, palmar flexion, ulnar translocation, and dorsal carpal subluxation are four, not uncommon, post-traumatic carpal ligamentous instabilities. Palmar carpal subluxation is a theoretical possibility. Dorsiflexion and palmar flexion instabilities are named for the way the distal lunate articular surface dorsally and palmarly, respectively. Ulnar translocation, and dorsal and ventral ca...

Carpal instability nondissociative.

Carpal instability nondissociative (CIND) represents a spectrum of conditions characterized by kinematic dysfunction of the proximal carpal row, often associated with a clinical "clunk." CIND is manifested at the midcarpal and/or radiocarpal joints, and it is distinguished from carpal instability dissociative (CID) by the lack of disruption between bones within the same carpal row. There are fo...

Post-traumatic lateral instability of the cervical spine.

Instability following sagittal distraction and rotational injuries of the cervical spine has been widely reported. We here report a case of post-traumatic segmental instability in the coronal plane. Case report. A 66-year-old farmer presented with painful torticollis having fallen into a ditch the previous day. He experienced immediate neck pain, but did not lose consciousness. He had a left te...
