Objective:
The role of prophylactic musculocutaneous flap closure following posterior spine surgery remains under-characterized. This study presents a single-institution experience with paraspinous-only musculocutaneous flap reconstruction among high-risk patients following spine surgery. Associations between risk factors, surgical indication, intraoperative characteristics, and postoperative wound complications are explored.
Methods:
A retrospective chart review identified all cases of prophylactic paraspinous flap reconstruction following posterior spine over an 11-year period. Patients who had uncomplicated postoperative courses were compared to those who developed wound complications. Multivariate logistic regression characterized associations among risk factors, surgical indication, and wound complications.
Results:
Two hundred fifty-seven patients underwent primary prophylactic closure using paraspinous musculocutaneous flaps only. 49.4% female, with a mean age of 60.7±13.9 years. Surgical indications included degenerative disease (n=124, 48.2%), tumor (n=78, 30.4%), deformity (n=22, 8.6%), congenital anomaly (n=18, 7.0%), and trauma (n=15, 5.8%). This population exhibited high-risk features, including diabetes (19.5%), history of smoking (53.3%), prior spine surgery (58.8%); mean body mass index was 30.1±6.9. Wound complications occurred in 37 patients (14.4%). Postoperative complications coincided with greater number of incised levels, higher degree of instrumentation, and longer closure length.
Conclusions:
Prophylactic flap closure was associated with wound complication rates consistent with the literature in cohorts with substantial comorbidity burden. Outcomes were predominantly influenced by procedural factors rather than baseline patient characteristics. The findings support the feasibility of prophylactic flap closure in high-risk patients across the spectrum of spinal indications. Controlled studies are necessary to evaluate effectiveness.
