Thumb Immobilizer - Rigid, Breathable Hard Shell Design for Ultimate Protection and Support. (Replacement Liner - Small)

As a physio, I recommend this support predominantly for people with osteoarthritis of the thumb joints (there are several here), and it works very well because it allows the top thumb joint to be moveable, whilst supporting the arthritic joint/s. What it is not for, is tendon problems like D'Quervains which needs the whole of the thumb including the end joint, and mid forearm splinting to stop the tendon from working - so it is not the splint that is at fault in the bad reviews but the inappropriate splint for the job (bit like you cant put a round peg in a square hole)

Perfect fit and keeps my thumb completely firm. The size it ideal and with the light colour makes it far less bulky and noticeable compared with others on the market. Very happy with this purchase.

Perfect. Does exactly what it says and is really helpful for basal thumb arthritis

Too rigid for me and uncomfortable. It seemed wide at the base of the thumb, but the actual length from top of the thumb to the wrist seemed too short. I know it’s supposed to prevent movement of the thumb but if I’d have worn it, I felt it would have rubbed. The slinky material underneath used as protection wasn’t any use either. Feel for the price of it, could have been better. Not for me.

Very comfortable

Made a massive difference to immobilising my thumb joint.

I have de Quervain's. GP recommended a thumb spica (by phone in these pandemic times). He was unable to prescribe but gave me an idea what to look for. I decided to invest as have been in so much pain for almost 3 months. I can see why this is designed as it is and on wearing initially thought was going to be fine. However, I am also a lady of a certain age, which possibly has relevance, but the bone in my right hand side of my wrist is agony , as is the area just below and ANYthing sitting on that area for more than a minute or two is agony beyond belief. I could cry it is so painful. Unfortunately, this product sits on top of that area. I tried inserting a pad, a very thick pad, on top of my wrist bone to cushion it and wear this splint but sorry no. Agony, and the area would swell up alarmingly. Twenty quid down the drain! If you have de Quervain's and the pain is in more than your thumb, this is probably not for you. No idea what is, but not this.

This is really good as my thumb keeps slipping out of place
