Abstract

Purpose: To obtain epidemiologic data on the Linburg-Comstock anomaly in Malaysia and to study the effect of the anomaly on key pinch strength.

Methods: We examined 292 healthy subjects (162 female and 130 male) bilaterally for the presence of the Linburg-Comstock anomaly. Each subject's key pinch strength was measured bilaterally using a pinch meter.

Results: The Linburg-Comstock anomaly was present in 101 of the 292 subjects (35%). Sixty-five subjects (22%) had it unilaterally, and 36 subjects (6%) had it bilaterally. The anomaly was associated with superior key pinch strength.

Conclusions: The study provides epidemiologic data of this anomaly in Malaysia and considers its anatomical influence on key pinch strength.

Type of study/level of evidence: Prognostic IV.
