Key Concepts

Median Nerve Compression

Another important complication is the compression of the median nerve, which can result in sensory and motor deficits in the hand. Recognizing this complication early is essential for appropriate management and to prevent chronic nerve damage.

Avascular Necrosis

A common and serious complication associated with these dislocations is avascular necrosis, where disrupted blood supply leads to bone tissue death. This late complication can significantly affect the structural integrity and function of the wrist.

Acute Wrist Dislocations

Perilunate and lunate dislocations are types of acute wrist injuries that involve the misalignment and disruption of the normal carpal bone configuration. Correct diagnosis and management are critical to restore function and prevent long-term disability.

Emergent Orthopedic Evaluation

These injuries are considered orthopedic emergencies because timely intervention is necessary to realign the carpus, prevent neurovascular compromise, and minimize future complications. Early orthopedic consultation is typically required in the management of such dislocations.
