title: Minimally invasive pars approach for foraminal disc herniation.
abstract: We present a retrospective cohort study on the outcome of patients with foraminal disc herniations (FDH) treated with partial pars resections using minimally invasive surgery (MIS) through a tube. FDH present a challenge due to the more lateral trajectory needed for their excision and thereby more muscle dissection and possibly facet resection. Forty patients, 19 women and 21 men with a mean age ± standard deviation of 58 ± 12 years, underwent MIS for FDH. Data on length of hospital stay, body mass index and outcomes were collected prospectively and reviewed retrospectively. Average length of stay following surgery was 1 ± 1 days. There was one wound infection and four unsatisfactory results. Using the Macnab score, good to excellent results were achieved in 89% of the patients. Based on these results, MIS surgery with partial pars resection is an attractive option in the treatment of FDH with low morbidity and short hospital stays.
