Chronic Lunate Dislocation: An Unusual Cause of Carpal Tunnel Syndrome—Avoiding Diagnostic Pitfalls and Synopsis of Management Options

ABSTRACT

ABSTRACT Carpal tunnel syndrome (CTS) represents the most common compressive neuropathy of the upper limb (1). There are a myriad of causes of CTS, of which carpal fractures and dislocations are known aetiologies. Volar lunate dislocations are the most common carpal dislocations described (1). Approximately 25% of perilunate dislocations are missed on initial presentation, resulting in delayed diagnosis and likely poorer outcomes (1-3). A case of chronic lunate dislocation presenting as CTS is presented here to highlight diagnostic pitfalls and management options.
