Thanks for your query at DoctorSpring.com
I understand your concern
I have read your question with diligence.It looks that you had rupture of distal biceps about a year ago.I want to confirm this for your knowledge tat biceps tendon can be repaired at early stage if tissue quality is good.In early stages, there are chances of less complication like nerve injury, success of repair, etc.
In late stages, the main problem is of tissue quality, scar formation at rupture ends & retraction of the tendon.There are still methods which can help in lengthening of the tendon, the graft is used from the back of thigh or from muscles on a lateral aspect of the thigh.Such surgery needs a good expertise & you should have this get performed only by an experienced senior orthopedic surgeon. Please find a senior surgeon near your location.
Hope this will help you.
