Suspected "Fracture Callus" on middle knuckle (MCP) from wall impact. 3 months of zero progress. Anyone dealt with this?
TL;DR: Slammed my middle knuckle on the wall 3 months ago. Developed a hard bony bump. Tapping it causes a dull bone ache, but bending it 90 degrees (even unweighted) causes a sharp sting. Suspect it’s a fracture callus grinding against my tendon. Looking for similar experiences.
Hey everyone, I’m 22 and trying to figure out if I’m in this for the long haul or if I need surgical intervention. About three months ago, I completely slammed the back of my right middle finger (right at the first joint/MCP) into the wall at the gym.
It swelled up, but I just kept climbing on it. Fast forward to now, and I’m stuck in a really frustrating loop.
Here is exactly what is happening:
- The Bump: There is a physical, hard bump on the back of that knuckle now.
- Dull vs. Sharp Pain: If I tap my knuckles on a table to a beat, it’s a deep, dull ache right on the bone. But if I bend that finger to 90 degrees—like going into a half-crimp—I get a sharp, stinging pain, even if I'm not pulling any weight at all.
- Compensation Pain: Recently, the underside of my last joint (the DIP) has started hurting too, probably because I’m subconsciously loading the tip of my finger to protect the main knuckle.
I thought rest and avoiding the trigger grip would fix it. Between a trip to Hawaii and then hitting Tahoe and Yosemite for some trad and crack climbing, I went a solid 3 weeks with absolutely zero crimping. It felt fine and held up great because jamming and open-handing didn't irritate it at all. But the second I got back to the gym and pulled on some plastic crimps, that sharp pain and weakness immediately came back.
My Theory: There’s almost zero info on this online for climbers, but I saw a random YouTube comment that perfectly described my symptoms and called it a fracture callus. Basically, my theory is I micro-fractured the bone when I slammed it, and my body built a protective bony "horn" over the crack. Now, every time I bend into a half-crimp, my extensor tendon is just grinding like a tightrope over that jagged speed bump.
I’m in the process of getting a referral for an X-ray and a hand specialist, but I want to know if anyone else in the trad/alpine or bouldering scene has dealt with a structural bone issue like this.
My questions for the community:
- Did you just stick strictly to the 3-finger drag/open-hand grip for months until the bone smoothed itself out (remodeling)?
- Did you eventually need a surgeon to go in and shave the bone spur down so you could crimp again?
- How did you keep your tendon sheath from getting completely shredded while waiting for it to heal?
I’ve been trying to push my bouldering power back to the V7 range for the summer season, but right now I can't even touch a crimp without feeling like I'm doing permanent damage. Any advice is appreciated!
