[When fracture pain does not subside. Recognizing complications].

Abstract

Over the long term, the evolution of pain caused by fractures is determined by the quality of immobilization, the extent of edema, and by surgical, analgesic and physiotherapeutic treatment. Development of chronicity is initiated by secondary deterioration, persistence of pain in the absence of improvement, changes in the nature of the pain, its spontaneous occurrence, and the appearance of concomitant symptoms. Differential diagnostic considerations must include surgical complications, but also damage to nerves, or the complex regional pain syndrome (CRPS). A particular differential diagnostic problem is the differentiation between CRPS and other complications. Treatment must be matched to the diagnosis: conservative attempts at treatment may have to be followed up with surgical revision. Drug treatment of pain is oriented to the stepped WHO schema. Physiotherapy, physical treatment and ergotherapy play a major role in the treatment of CRPS.
