A 25-year-old, right-hand-dominant, manual labourer sustained an isolated injury of the right wrist after a fall from a low height. However, the patient didn't initially seek medical attention. Five weeks later, he attended the outpatient clinic complaining of pain during work or daily activities and deformity at the dorsal and ulnar surface of the right hand. The affected area was tender to palpation and any movement of the base of the fourth and fifth metacarpal bones was very painful. Radiographic evaluation revealed a hamatometacarpal joint fracture- dislocation (Figure 1). Under general anaesthesia, a dorsoulnar approach was performed and a divergent hamatometacarpal joint-dislocation involving the fourth (dorsally displaced) and fifth (palmary displaced] metacarpal bases was identified.
