Abstract
OBJECTIVE: To review the causes and demographics of Linburg syndrome. DESIGN: An illustrative case report and a demographic study. SETTING: Adult and pediatric orthopedic clinics at the Health Sciences Centre in Winnipeg. PATIENTS: One patient with Linburg syndrome and 200 patients and relatives presenting to adult and pediatric orthopedic clinics with conditions not involving their hands, wrists or forearms. OUTCOME MEASURES: The presence of the intertendinous anomaly and of carpal tunnel syndrome. RESULTS: Tendinous connection(s) between flexor pollicis longus and flexor digitorum profundus muscles were found in 20% of the study population. The anomaly was found in all age groups. No association was found between Linburg syndrome and the presence of carpal tunnel syndrome or previous injury to the hand or forearm. CONCLUSION: Tendinous connection between flexor pollicis longus and flexor digitorum profundus muscles is a common anomaly that rarely causes clinical symptoms.
