Rock climbing

Rock climbing also lightly called 'The Gravity Game', is a sport in which participants climb up, down or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a pre-defined route without falling...

Sports injuries

Sports injuries are injuries that occur in athletic activities. In many cases, these types of injuries are often due to overuse or acute trauma of a part of the body when participating in a certain activity. For example, runner's knee is a painful condition generally associated with running, while...

 that usually manifests in a swollen middle or ring (most commonly ring) finger. It is due to a damaged flexor tendon pulley, normally the A2 pulley (can also be the A3) and normally caused by trying to support your body weight with one or two fingers.

Continued climbing on an injured finger, will probably result in double or triple (or more) downtime in order to recover.

Treatment Tips for Finger Tendon Pulley Injuries

This is a compilation of information from these sources.

1. Immediately cease climbing and any other activity that puts stress on the injured finger. Consult a doctor if there is noticeable “bowstringing” on the flexor tendon or if you are the least unsure about the nature of the injury.
2. There are different theories out there for the preferred line of approach. Some argues for the use of NSAIDs and ice for visible swelling only, others argue Diclofenac sodium should be applied and carefully rubbed in on the injury until the swelling starts to give. Smokers should consider breaking the habit, since smoking has been shown to slow healing of tendons and ligaments.
3. When the pain and swelling is gone (depending of the grade of the injury, 1-4 weeks), begin with an active healing process - containing squeezing putty clay or a stress ball. Combine this with light massage and mild stretching to ensure your finger will heal properly and better prepared for future stress. The use of heating pads and cold water baths are also mentioned in several sources in order to increase blood flow. Use this therapy for about twice as long as the previous resting period (2-8 weeks) before gradually returning, with the utmost care, to climbing.
4. Gradually return to climbing while using prophylactic taping every time you climb, and spend the first weeks climbing relatively easy routes with big holds, good footholds and keep your sessions short and stay away from overhangs and campus areas/boards.
5. Return to full-force climbing if easy climbing yields no pain. Continue taping (it will also serve as a mental note of the previous injury) and avoid tweaky crimps and pockets for several months, since complete tendon healing can take 100 days or more.
