Elastic fixation of mallet finger fractures using two K-wires: A case report of a new fixation technique

RATIONALE: Mallet finger fracture is a common sports-related injury that may lead to the tearing of extensor tendon and protrusion of a bony fragment located at the base of the distal phalanx. We affirmed that the elastic fixation of with two K-wires technique is a good method to deal with Mallet Finger fractures that fractures could gain effective fixation than the conventional treatment method and avoid surgical incision complication PATIENT CONCERNS: We reported a 33-year-old female patient came to our hospital complaining of mild pain, swelling and her right little finger was deformed because of sport's injury. DIAGNOSIS: Acute mallet finger fracture type IV B according to Doyle classification of mallet injuries. INTERVENTIONS: We performed an emergency operation for the elastic fixation of the mallet finger fractures with two K-wires. OUTCOMES: After the surgery, the patient showed functional recovery. No evidence of recurrence was noted 6 months after the operation, and the patient showed no symptoms of sports-related injuries. LESSONS: We discuss the clinical diagnosis, treatment, and follow-up of the patient and suggest that elastic fixation with two K-wires is a good method to treat mallet finger fractures.
