Abstract
Type of study: Case-series comparison.
Patients: 20 patients (2 males); average age 15.5 years; mean follow-up 22 months. 10 patients (Lenke type 1) had anterior correction and instrumentation; 10 patients (Lenke type 2) had posterior operations. All patients had a selective thoracic fusion (with the type 2 curves having instrumentation incorporating the proximal thoracic curve).
Outcome measures: Complications, radiological parameters (Cobb correction of major & compensatory curves); trunk shape (rib hump / scoliometer), and SRS-22 questionnaires.
SRS-22 outcomes: There was no significant difference in the pre-operative individual domain scores (pain, self-image, function, mental health, satisfaction) between the two groups. There were no differences in the postoperative results (including self-image) apart from pain. The anterior surgery group had more persistent pain, but at a similar level than preoperatively (3.2 [0.8] vs 4.6 [0.3], p~0.03).
Conclusion: For right thoracic (Lenke curve types 1& 2) late-onset idiopathic scoliosis both types of surgery deliver similar radiological and trunk-shape results. SRS-22 self-image and function post-operative results are also similar. The anterior procedure did not however improve the pre-operative pain score.
