Subject: Question listserv regarding Alps clutch locks
Over the last few months I have had numerous complains from patients regarding the Alps S496T clutch lock. All have reported intermittent loosening of the Pin from the lock mechanism. They claim that the pin backs out to the point where they have to reseat the pin via the clutch mechanism. In some cases they claim that it completely disengages and the prosthesis falls off. I have never observed these situations, nor have I been able to replicate their complaints in my facilities.
I have also had issues with this lock's pieces coming apart. This is what I have witnessed. 1) The Housing (clutch) Assembly coming loose and backing out of the lock body (I followed the Manufacturer instructions using loctite 262, but no torque specs are in the instructions.) 2) The push button/screw has came loose and fell out, (also followed instructions.) 3) A little play or wiggle when the pin is engaged.
The first few times the situation was reported I wrote it off as noncompliance of a rouge patient, but I have too many reports of this happening from a wide range of patients to ignore. I reported the situation to the manufacturer. They said that they have never had a complaint, or had such reports regarding this lock.
I have issued a product alert to my patients asking them to come in if they are having any such problems. So far I have remade 4 sockets, 3TF,1TT because of these reported problems.
Am I the lone practitioner having these issues? If you have had similar reports please contact me, and the manufacturer ASAP.
Respectfully Yours,
