Radial styloid fracture with 1st extensor compartment muscle
Radial styloid fracture and concomitant first dorsal compartment proximal musculotendinous avulsion is an extremely rare injury. This togetherness is difficult to diagnose fully on routine physical examination.

Published in the International Journal of Surgery Case Reports, the authors present a case of a a thirty nine year old male patient who suffered musculotendinous avulsion injury of the extensor pollicis brevis (EPB) tendon and abduc- tor pollicis longus (APL) tendon that is rarely accompanied by a closed, non-displaced radial styloid fracture developed following an in-car traffic accident.

Diagnosis of avulsion was made with preop- erative magnetic resonance imaging (MRI) and the fracture was fixed with open reduction. The measurements of isometric APL and EPL muscle strength for two thumb were performed using a digital hand dynamometer, no statistically significant difference was found between the muscle strengths of the affected and non-affected thumbs at the postoperative second year follow- up.

Learning Points:-
• The literature does not hold enough cases to establish the grounds for hypotheses related to the injury mechanism in the 1 st extensor tendon musculotendinous injuries ac- companying radial styloid fractures.

• Although the diagnosis of the injury in this case was inadvertently made with preoperative MRI, the routine application of MRI does not seem to be cost-effective.

• The authors suggest that checking and assuring the intactness of the 1 st extensor compartment with a gentle traction during surgery should be a routine step in the treatment of radial styloid fractures treated with open reduction.
