No cure; treat symptom. Promote optimum mobility- therapy, rest, hot/cold treatments, steroids, NSAID, immunosuppressants, assistance device, Calcitonin. Diet – lo purine diet, Calcium, Vit. D. MusculoskeletalSummary - 2 : MusculoskeletalSummary - 2 Prevention- infections, stress, no rest. Surgical intervention – removal of in case of cancer, internal fixative device for Scolosis, or hip or knee replacement with prothesis for degenerative joint disease, rheumatoid arthritis. Key – prevent complications, patient teaching and achieve optimum level of mobility.
