1yr ago removed implant for distal humerus elbow fracture. Arm partial stiff & triceps atrophy, no progress. Continue physio, try surgery, or no hope?

Get 2nd opinion. Elbow fractures that require orif( open reduction and internal fixation) are prone to elbow stiffness. If p.T./ bracing( dyna splint to improve extension) is not improving your motion consider seeing an ors who is proficient @ elbow arthroscopy. Arthroscopic release can improve elbow motion dramatically in some pts. It can be technically demanding so speak w/ your ors and see if this is an option.
