I would suggest speaking to someone who deals with prosthetics. It will be interesting to learn to control whatever extension is possible without the benefit of the touch sensation. I pray you receive whatever gift you need to be able to play again.

Im not sure if you will find a satisfactory prothetic device. HOWEVER I can thnk of two options for you: 1) Find someone who does QUALITY sax repair/remanufacturing that can fashion/engineer for you a new octave key . First you will have to move the left thumb rest over to where your "new/current" thumb placement is. Then you'll know where and how much the octave key will have to be repositioned. 2) Forget the octave key mechanism. Move or add a new thumb rest. Now for the tricky, but ultimately very REWARDING part. The first Adolph saxes did not have octave keys. saxophonists learned to vary pitches and octaves by speeding up the air, or overblowing. When I began learning how to play in the altissimo ranges my mentor showed me about overblowing and multiphonics. I'm still learning. But very easily (well it seems very eay now) I was able to play up and down the entire scale of the sax up to false fingering high E,F, and G without using the octave key. At will. With my new Keilwerth tenor and alto matched with vintage berg stainless duckbill mouthpieces and Plasticover (tenor) and, unbelievably, a Fibracell (alto) reeds I was able to finger a low Bb and, without using the octave key I played: low Bb, middle Bb, high F#, high Bb, high D (normally the D with the one palm key and octave). That was a first on the alto today. effortless AND at will. Fingerng an overblowing all keys will allow you to play your horn. It requires more work but with the right teacher, patience, practice and determination (plus proper mouthpiece and reed combination) you may discover that your "handicap" could be your ticket to exploration an mastery of the sax. It could be a lot worse...could have lost one of your other fingers and then you would have a real problem. Good ole stumpy can still do the main job of supporting your horn in your grasp and you can become Lenny Pickett with your new skills at mastering your embrouchure and manipulating air flow and airspeed to get the notes nd sound you need. I bet the folks here on the forum can direct you to an instructor and/or repair person to help you modify your axe for you. The folks at saxquest could probably do the engineering for you , or at least refer you to someone. hope this was helpful, Jeff Just a thought....
