Right Ring Finger Volar Mass in a 14-Year-Old Boy

Area of Science:

• Orthopedics
• Pediatric Hand Surgery
• Musculoskeletal Disorders

Background:

• Trigger digits are uncommon in adolescents, with etiologies differing from adults.
• Pediatric trigger digits often stem from anatomical variations like tendon thickening, abnormal tendon relationships, or pulley constriction.
• Associated conditions include mucopolysaccharidosis, juvenile rheumatoid arthritis, Ehlers-Danlos syndrome, and CNS disorders.

Observation:

• This case report focuses on a less common cause of triggering: intratendinous or peritendinous calcifications and granulations.
• The patient presented with tenosynovitis characterized by psammomatous calcification.

Findings:

• Surgical intervention involved excision of the calcified mass from the flexor digitorum superficialis tendon.
• Release of both the A1 and palmar aponeurosis pulleys was performed.
• This treatment addressed the tenosynovitis and associated triggering in the adolescent.

Implications:

• This case expands the understanding of trigger digit etiologies in adolescents.
• It underscores the importance of considering calcific tenosynovitis in pediatric trigger digits.
• Successful surgical management highlights effective treatment options for this rare presentation.
