    Abstract:
    PURPOSE OF THE STUDY:  Fractures of the distal radius are frequently associated with injuries of the scapholunate (SL) and lunotriquetral (LT) ligaments. Our study is aimed at revealing their hidden lesions by employing a fast and accessible fluoroscopic identification. PATIENTS AND METHODS:  We investigated 40 patients who were indicated for plate osteosynthesis of distal radius fracture. After completing the osteosynthesis, the procedure was concluded with a wrist arthrography. The patients with SL and LT interval lesions had their wrists immobilized by a plaster splint while patients with normal findings with an elastic bandage. The patients were followed up for 12 months after the surgery. The functional results were evaluated by Mayo wrist score. RESULTS: The intra-operative examination identified 62.5 % of patients with lesions of SL and/or LT interval, and 37.5 % of patients were lesion-free. The Mayo wrist scores after 3, 6 and 12 months in patients whose wrists were not immobilized were 72, 86.3, and 86.3, respectively. The latter scores in the group of patients with external immobilization were 54.4, 82, and 84.8, respectively. The difference between the groups was significant three months after the surgery. After six and twelve months, the difference became negligible. CONCLUSION:  The exclusion of hidden lesions allows earlier rehabilitation, while in patients with signs of lesions, it is appropriate to immobilize the wrist (Tab. 1, Fig. 3, Ref. 31).
