Scapulothoracic fusion: outcomes and complications.

BACKGROUND

Scapulothoracic fusion (STF) may be an option to alleviate pain and restore function. The purpose of this study is to report the clinical outcome of patients who underwent STF for the treatment of painful scapular winging.

MATERIALS AND

METHODS

From 1999 through 2008, 10 patients (12 shoulders) underwent an STF for painful winging of the scapula. The mean follow-up period was 41 months (range, 8-72 months). Indications for STF included winging in association with excessive medial and/or lateral clavicular resection and facioscapulohumeral dystrophy, as well as scapular winging related to combined long thoracic and spinal accessory nerve palsy. A retrospective review was performed to evaluate the subjective shoulder value, visual analog scale score, range of motion, unions, and complications.

RESULTS

There was a statistically significant improvement in the subjective shoulder value, visual analog scale score, range of motion, and satisfaction postoperatively. The overall complication rate was 50% (6 of 12). There were 2 persistent nonunions (2 of 12, 17%), and 50% (6 of 12) of all fusions required subsequent hardware removal because of discomfort. Complications included pleural effusion (3 of 12, 25%), hemopneumothorax (1 of 12, 8%) pulmonary embolus (1 of 12, 8%), and infection (1 of 12, 8%). With the exception of the revision nonunion, all complications resolved with no negative sequelae.

CONCLUSION

STF results in improved function and pain relief. STF is associated with a high short-term complication rate with limited long-term sequelae.
