Finger Pulley Injuries

Rock Climbing Flexor Pulley Injury

What is a finger pulley?

Each of the fingers has multiple pulleys.  Pulleys act like a system of tunnels holding the tendons that flex the fingers in place.  Without a functional pulley system, the flexor tendon would bowstring away from its proper position.  Picture a fishing pole with one of the eyelets missing. The missing eyelet causes the fishing line to bowstring away from the pole.

Why does it occur?

Pulley injuries often occur after extreme force is placed on the flexor tendons of the fingers. Flexor tendon injuries are therefore commonly seen in baseball pitchers and rock climbers.


Patients most commonly experience pain on the palm side of the affected finger(s).  This pain may be accompanied by swelling and difficulty flexing the finger.  Patients may also notice decreased grip strength.


Diagnostic testing:

An x-ray may be performed to rule out a fracture or avulsion injury. An ultrasound and/or MRI can often be helpful to confirm the diagnosis.

Treatment Options:

The majority of pulley injuries can be treated nonoperatively.  Like many diagnoses, it is imperative that the treatment is initiated ASAP to maximize results.  Most patients will be placed into a pulley protection splint or pulley ring that supports the pulley while it heals, and will remain in this splint for approximately 6 weeks.  

Surgical Treatment:

Surgery to repair or reconstruct the pulley may be recommended should a patient continue to experience significant pain, instability or bowstring despite nonoperative treatment.

Recovery Expectations:

Patients will be placed into a custom pulley protection splint or pulley ring at their first postoperative visit.  Patients will usually remain in either the splint or pulley ring for 6 weeks, after which therapy is usually started.  Patients usually return to normal activities at 3 months post-op.
