possible internal leg injury - what to do?

[Wolfram1]

So i have noticed that one of the two, the larger one actually of the 0.0.2 Thrixopelma cyaneolum slings (this one) i bought a couple of moths ago had a "weak" back leg, especially the one side and would not move as nimbly as it was trying to. The leg would noticeably get in the way and be bent in weird angles, but at the same time it is still mobile and if given time the spider will adjust it to a normal position. It just can't move it well or seem to put any real weight on it without it bending/buckling as if the internal muscles were not properly connected.

I had hoped it would manage to heal the issue with a moult, but it has gone through 2 successful moults without any noticeable change. It is otherwise fine, eating, moving stuff around, etc. it's still just the one/possibly two back legs that keep buckling away when it tries to put weight on it. Which probably only happens when it reacts to me disturbing it in order to feed or do maintenance, trying to turn around and scuttle away but getting caught on its own leg as it tries to turn. The articulation of the tarsus seems to be especially limited/weak.

I am debating whether i should make it autotomize the leg after getting its condition back into a good shape. If i act now it will be much easier for it to regrow the affected leg than if i keep waiting for it to grow larger, but at the same time i am weary of causing it further harm. Also, i have never read about this issue before so i would like to know what you guys would do if you were in my shoes. Thx.

Personally, I’d leave him be if it’s not bothering him. He can remove it himself if it becomes an issue. My concern would be with molting, but if he’s done it successfully twice, it isn’t impeding him..yet.

I'd leave it alone esp as you describe how it's doing. Great species!!!!!!!!!

A sling should be fine.

yea it does not seem to be injured outwardly, just comparing the movement with other healthy spiders it becomes evident something is clearly wrong with the mobility of the back legs, i just watched it drag the leg when walking again.

thx for the advice to you all, i will leave it be for now

Its what i did with one of my g pulchripes. It was wobbly for less then a month. Molted super quick, quicker then usual. With brand new gear. Did not even notice the new leg had replaced a gimp one.

for reference

apart from the difficulty moving it seems healthy, no dehydration or poisoning, at least it does not seem like it, it seems more like something internal, an injury or perhaps neurological

give me your thoughts, perhaps it was simply born this way?

my second one behaves perfectly normal but grows much slower
