Pediatric Trigger Digits

Pediatric trigger thumb (PTT) and finger (PTF) are upper extremity deformities that frequently go unrecognized by providers. Early recognition by pediatricians and caregivers is vital because PTT is successfully treated nonoperatively in more than 95% of patients if diagnosed early. Similarly, PTF can be successfully treated nonoperatively in 67% of patients. Although PTT is typically benign and 10 times more common, PTF may be associated with underlying concurrent medical conditions, such as juvenile rheumatoid arthritis, diabetes, mucopolysaccharide and lysosomal disorders, and trisomy 18. Routine examinations consisting of full hand range of motion should be performed in all children. Clinicians should be aware of the importance of conservative treatment options for PTT and PTF and the value of screening for underlying medical conditions associated with PTF.
