Wiltse approach TLIF for the treatment of single-segment thoracic spinal tuberculosis with neurological deficits and osteoporosis in the elderly: a retrospective study of 20 cases

Abstract

BackgroundThis study aimed to explore the clinical efficacy of Wiltse approach transforaminal lumbar interbody fusion (TLIF) in the treatment of single-segment thoracic spinal tuberculosis with neurological deficits (STSTND) in elderly patients with and osteoporosis.MethodsThis study conducted a retrospective analysis of 20 STSTND patients who underwent Wiltse approach TLIF in our hospital from January 2017 to January 2019. The follow-up time was 37.15±7.37 months (range 24-48 months), and the kyphotic angle was 35.41±6.71°. According to Frankl spinal cord injury classification assessment of neurological deficits. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are used to assess the activity of tuberculosis (TB). Femoral neck bone mineral density measurement T value (BMD T) is used to assess the degree of osteoporosis.Result20 patients with spinal tuberculosis (STB) were completely cured without tuberculosis recurrence. The postoperative kyphotic angle was 8.80±0.79°, and there was no significant loss of correction at the last follow-up. In the case of combined osteoporosis, the bone grafts fuse within 6-9 months and the back pain was relieved. The neurological condition of all patients improved after the operation.ConclusionsWiltse approach TLIF treatment plus anti-tuberculosis chemotherapy is adequate for obtaining satisfactory healing of single-segment thoracic tuberculosis with neurological deficits and osteoporosis in the elderly.
