Surgical treatment of acromiodavicular dislocation (Tossy Ⅲ) with coracoclavicular screw and clavicular hook plate fixation:a comparative study / 中华创伤杂志

ABSTRACT

Objective To compare clinical outcomes of clavicular hook plate and coracoclavicu-lar screw fixation in treatment of acrmioclavicular dislocation (Tossy Ⅲ). Methods From August 2003 to January 2008,38 patients with acromioclavicular dislocation (Tossy Ⅲ) were randomly divided into two groups that were treated with coracoclavicular screw and clavicular hook plate fixation respective-ly. The range of shoulder movement was restricted after operation until the fixation was removed three months later. The shoulder function was evaluated by using Japanese Orthopedic Association (JOA) sco-ring system. The functional scores were compared before and after removal of the internal fixation in two groups. Results All patients were followed up, which showed no statistical difference upon final shoulder function of two groups. There was no loosening or migration of internal fixators. No redislocation occurred after removal of internal fixations. Seven patients complained shoulder pain and three had severe shoulder pain affecting sleep quality in coracoclavicular screw group. The pain was alleviated after remov-al of fixation. Conclusions Coraeeclavicular screw and clavicular hook plate fixation have similar clinical effect in treatment of acromioclavicular dislocation (Tossy Ⅲ), with satisfactory recovery of shoul-der function. Many complications of acromioclavicular fixations can be avoided by restriction of shoulder movement after operation and early functional exercise after removal of fixation.
