Abstract

Background: Linburg-Comstock anomaly is typically defined as a tenosynovial interconnection between flexor pollicis longus and flexor digitorum profundus tendon of the second finger. There are several studies stating that the current anomaly is congenital or acquired. The aim of this study is to reveal whether overuse, which is mostly reported as an acquired etiologic factor, effective in development of the current anomaly. Methods: Three hundred thirteen medical secretaries who work with computer keyboard at least 6 hours a day were defined as study group. Three hundred twenty-three volunteers without jobs who necessitate continuous and repetitive hand and finger activities were defined as control group. All individuals were examined by an orthopaedic surgeon. Additionally, cases with Linburg-Comstock anomaly were evaluated in respect of forearm pain and subjective findings of carpal tunnel syndrome. Results: Linburg-Comstock anomaly was determined in 27.8% cases of medical secretary group and in 32.2% of healthy control group. In medical secretaries with Linburg-Comstock anomaly, 25.3% had forearm pain and 5.7% had findings of carpal tunnel syndrome. In control group with Linburg-Comstock anomaly, 21.2% had forearm pain and 13.5% had findings of carpal tunnel syndrome. No relationship was found between overuse of the hand and Linburg-Comstock anomaly and the symptoms accompanying the anomaly. Conclusions: The current study reveals that overuse is not an etiologic factor in Linburg-Comstock anomaly existence and related symptoms. We think that the current anomaly develops on congenital basis rather than acquired factors.
