Isolated post-traumatic rotary sub-luxation of the scaphoid: Management by triscaphoid arthrodesis

ABSTRACT

Eight patients with unilateral chronic wrist pain were operated upon by triscaphoid arthrodesis [scaphoid fused to both trapezium and trapezoid]. All the patients had a history of trauma and clinically had a positive scaphoid shift test. Radiologically all the patients were proved to have static [type 2] rotary subluxation of the scaphoid. The average postoperative follow up period was three years and two months. Evaluation of the results showed that in spite of postoperative decreased range of motion of the wrist, a significant improvement of pain and function was observed
