XXXX following displaced @entity174 of the middle clavicle.

@entity1 @entity174 @entity158 @entity717 @entity7109
PURPOSE: To evaluate the rate of @entity7109 and resulting @entity1 outcomes after treatment of displaced midshaft @entity174 . METHODS: Skeletally mature @entity1 with isolated, displaced midshaft @entity174 treated with or without surgery over a 16-month period were recruited. The minimum length of follow-up at study examination was 12  months. @entity1 outcomes were documented using the SICK (scapular malposition, inferomedial border prominence, @entity158 and malposition, and dyskinesis of @entity717 ) Scapula Rating Scale, the Simple Shoulder Test, 3 visual analog scales (VAS) for @entity158 , and shoulder range-of-motion and strength measurements. Of the 32 eligible @entity1 , 24 (75%) were successfully recruited. RESULTS: The mean @entity1 age was 46      17 years, with a mean length of follow-up at study evaluation of 1.7      1  years. Surgical fixation was performed in 12 @entity1 (50%). @entity7109 was present in 37.5% of @entity1 (n  =  9). @entity1 with @entity7109 had worse SICK scapula scores (5.8      2.2 vs 3.1     2.4, P  =  .01), worse Simple Shoulder Test scores (10.5      1.6 vs 11.7      0.8, P  =  .029), higher maximum VAS @entity158 scores (4.1      3.1 vs 0.97      1.2, P  =  .002), and worse average VAS @entity158 scores in the week before the examination (2.7      2.5 vs 0.2      0.4, P  <  .001) compared with @entity1 without @entity7109 . Range of motion and abduction strength were similar between the groups. @entity7109 developed in 1 @entity1 treated with surgery (8% [1 of 12]) compared with 8 @entity1 treated nonoperatively (67% [8 of 12]) (P  =  .009). CONCLUSIONS: @entity7109 is common after displaced middle-third @entity174 , and these @entity1 have more @entity158 and worse functional outcomes compared with @entity1 without @entity7109 . Surgical treatment may reduce a @entity1 's risk of @entity7109 developing and improve short-term outcomes.
