Abstract

In 1979, Linburg and Comstock reported a lesion that interfered with the independent flexion of the fingers due to an abnormal connection between the flexor pollicis longus and the tendon of the flexor digitorum profundus to the index finger. This entity can cause discomfort in daily life when functionally delicate finger use is required; therefore, surgical treatment is sometimes recommended depending on the symptoms. The authors performed surgical treatment for a patient who visited our outpatient clinic seeking functional improvement for congenital symptoms of simultaneous thumb and index finger flexion and obtained satisfactory results. Reports of surgical treatment for Linburg-Comstock syndrome are rare in Korea, so the authors report this experience, along with a review of the literature.

Abnormal tendon slip (arrows) was observed between flexor pollicis longus tendon and second flexor digitorum profundus tendon at the level of distal metaphysis of radius to metacarpal base level.

  Fig. 3. (A, B) Anomalous tendon slip (red arrows) was noted between flexor pollicis longus tendon and second flexor digitorum profundus with tenosynovitis. (C, D) The anomalous tendon slip, measuring about 8 cm in length and about 2 mm in diameter, was resected.
