<s>[INST] Hi had big toe fusion 7 weeks ago due to arthertic joint. Got infection in scar and orthopedic doctor says ive got mobility in joint still. I had non union on other big toe last year and hope it doesnt happen again...he used titanium plate and 6 screws so surely it shudnt move at all any info would be good thanks [/INST] Hi, thank you for providing the brief history of you. A thorough musculoskeletal assessment is advised. As, the toe is a small bone and any surgery performed will be totally dependable on the metabolism of the individual. Also, due to infection the healing is delayed, and the non-union is possible. As you are having arthritic joint, there is a possibility of less calcium in the bone and the bone is small to have proper calcium deposition. For the non-union, there needs to be the use of the bone graft to advance healing and the union can be expected. RegardsJay In Chat Doctor.  </s>
