Mallet thumb is
the avulsion of the extensor pollicis longus tendon from the base of the distal
phalanx with or without bony fragment. Abruption injuries of the extensor
tendon are rare in adolescents and in most of the cases complete
healing and functional restoration can be achieved
by conservative treatment.
However, when the
disruption is extensive (i.e., it affects more than one third part of the
articular surface) and the extent of the dislocation is more than 1.5 mm, then
surgical intervention is necessary.
To present the
feasibility of the Ishiguro’s method which is more beneficial than open surgery
in the treatment of mallet thumb fracture. Case report: A 16-year-old male
patient presented tenderness and swelling around the interphalangeal joint of
the right thumb.
X-ray imaging
showed fracture at the base of the distal phalanx including one third of the
articular surface. Under digital nerve block anesthesia we performed closed
reduction and extension block pinning. The right thumb was immobilized with
Bennet splint for 3 weeks.
