X ray of right hand had no fracture but showed mild DJD scaphoid multangular and first carpometacarpal joints. I want to have the carpal tunnel release surgery and would i need a joint replacement to the hand and can this situation develope from the thumb crush injury of 11/12/12 [/INST] His think you are having 2 different conditions which are not related to your crush injury in 2012. Bilateral carpal tunnel syn Chat Doctor.  Carpal tunnel release surgery is advised when everything else has failed to relieve symptoms, and it has a very good success rate. DJD around scaphoid and thumb carpometacarpal arthritis is also very common, it is first treated with simple pain medication, injections and when this fails there is wide range of surgical options to consider and this would not involve joint replacement. </s>
