33% of Rock Climbing Injuries are the Same. Why?

TL;DR

Crimping in rock climbing puts a high amount of force on the fingers, leading to a specific injury called a pulley rupture.

Key Insights

• 🖐️ Rock climbing injuries, particularly in the fingers, are common and often caused by the technique called crimping.
• 🥺 Crimping puts high forces on small holds, leading to a significant amount of torque and fingertip force.
• ❓ The A2 pulley is regularly overloaded during crimping, which results in pulley ruptures, a prevalent injury among climbers.
• ⚾ Climbing is a numbers-based sport that attracts many science-minded individuals due to its problem-solving nature and ability to quantify progress.
• 💀 General education and awareness about the dangers of crimping can help climbers prevent and address finger injuries.
• 🚙 Resting and strength training are essential for climbers to maintain their physical well-being while pursuing the sport.
• 🖐️ Supporting the pulleys with external tape can provide additional protection against finger injuries.

Questions & Answers

Q: Why do a large number of climbing injuries occur in the fingers?

Over a third of rock climbing injuries happen in the fingers because of the high forces generated by the technique called crimping, used to grab small holds.

Q: What is the reason behind the high forces on the fingers during crimping?

The physics behind crimping involves torque and force exerted on the fingers, with the crimp hand position causing the highest torque and fingertip force compared to other positions.

Q: What is a pulley rupture, and why is it a common injury among climbers?

A pulley rupture is a specific injury that occurs in rock climbers due to the high forces exerted on the fingers during crimping. The A2 pulley, in particular, is routinely overloaded and close to failure during this hand position.

Q: How can climbers prevent finger injuries from crimping?

Climbers can listen to their bodies, rest on sore fingers, take rest days, and incorporate strength training to efficiently move. Supporting the pulleys with external tape can also help prevent injuries.

Summary & Key Takeaways

• Over a third of rock climbing injuries occur in the fingers due to the technique called crimping, which puts high forces on small holds.

• Crimping generates a torque and force on the fingers, causing the highest torque and fingertip force compared to other hand positions.

• These high forces on the fingers lead to pulley ruptures, a common injury among rock climbers.
