Mallet Finger Treatment in Raleigh, NC
What is Mallet Finger?
Mallet finger, also known as baseball finger or drop finger, is a common hand injury where the tip of the finger cannot be actively straightened due to disruption of the extensor tendon at the distal interphalangeal (DIP) joint. This injury typically occurs when the extended finger experiences forceful flexion, such as when attempting to catch a ball or during direct trauma to the fingertip.
Types of Mallet Finger
There are two main classifications:
– Tendinous mallet: Rupture of the extensor tendon without bone involvement
– Bony mallet: Avulsion fracture of the distal phalanx where the tendon pulls off a piece of bone
Symptoms and Clinical Presentation
Patients with mallet finger typically present with:
– Inability to actively extend the DIP joint
– Characteristic drooping or flexed position of the fingertip
– Pain and swelling at the DIP joint
– Possible palpable bony fragment (in bony mallet injuries)
Diagnosis
Diagnosis is primarily clinical, based on the inability to actively extend the DIP joint while the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints are immobilized. Radiography (anteroposterior, lateral, and oblique views) should be performed to evaluate for an associated avulsion fracture and assess joint alignment.
Treatment
Conservative (Non-Surgical) Management
Most mallet finger injuries can be successfully treated with splint immobilization, which is the standard of care and achieves excellent outcomes even in cases of delayed presentation.
Splinting Protocol:
– Duration: 6 weeks of continuous immobilization for bony mallet; 8 weeks for tendinous mallet
– Position: DIP joint in neutral position or slight hyperextension
– Additional nighttime splinting: 4weeks after completing continuous immobilization
– PIP joint: Does not require immobilization
Splint Options:
Multiple splint types are appropriate, including:
– Stack splints (most commonly used); Padded aluminum splints;Thermoplastic splints; 3-point prefabricated orthosis with elastic tape; Cast immobilization
No single splint type has shown superiority over others.
Critical Patient Instructions:
– The DIP joint must remain in continuous neutral/extension position
– If the joint flexes during treatment, the recovery timeline restarts
– Splint should be worn even while bathing
– When changing the splint, the DIP joint must be held in extension the entire time
Surgical Management
Surgery is rarely indicated but special cases for example:
– Avulsion fractures involving more than one-third of the articular surface
– Volar subluxation of the distal phalanx
– Open injuries
– Failure of conservative treatment
Surgical options include percutaneous pinning and open reduction with internal fixation.
Prognosis and Outcomes
With appropriate conservative treatment, patients typically achieve:
– Less than 15 degrees of extensor lag at 6 months
– Minimal pain (mean 1.2 out of 10)
– Good functional outcomes
Bony mallet injuries generally have better outcomes than tendinous injuries, with significantly better extension lag results and faster healing times.
Complications of Untreated Mallet Finger
– Chronic DIP joint flexion deformity; Swan neck deformity (hyperextension of PIP joint with flexion of DIP joint); DIP joint osteoarthritis; Functional limitations
Key Takeaways
Mallet finger is a common, easily recognized injury that can be effectively managed in primary care settings with appropriate splinting. Success depends on patient adherence to continuous immobilization protocols. Most patients achieve excellent functional outcomes without the need for surgery or specialist referral.
Prevention of mallet finger can be accomplished by taking certain precautions, such as wearing protective gear when playing sports or performing activities that involve the hands. It is also important to exercise caution when handling heavy or sharp objects, and to avoid placing undue stress on the fingers.
In conclusion, mallet finger is a common injury that can be caused by a variety of activities, but is often seen in athletes who play sports involving catching and throwing a ball. Early diagnosis and treatment are essential to prevent long-term complications, and prevention can be achieved by taking appropriate precautions to protect the hands during activities that may place them at risk of injury.
