Stress injury of the lunate in tennis players: a case series and related biomechanical considerations.
OBJECTIVE
To investigate clinical and imaging differential diagnosis and tennis stroke biomechanics potentially involved in lunate stress injury pathogenesis.


METHODS
The present report describes five competitive tennis players with overuse-related dorsal wrist pain assessed by magnetic resonance imaging.


RESULTS
Magnetic resonance imaging revealed the presence of lunate stress injury. All players were treated conservatively, with symptom resolution and complete functional recovery achieved at 14 weeks.


CONCLUSIONS
Lunate stress injuries should be considered in the differential diagnosis of overuse-related dorsal wrist pain in tennis players.
