RÉSUMÉ
Methods@#In this single-center double-blind randomized controlled pilot study, 46 patients were recruited and randomized by the lottery method. The Visual Analog Scale (VAS) for leg pain, modified Oswestry Disability Index (mODI), and Short-Form 12 (SF-12) were assessed at 1 week, 3 weeks, 6 weeks, 6 months, and 1 year. @*Results@#Both groups were comparable in terms of demographics, preprocedure VAS scores, mODI, and SF-12 scores (p=0.52). At the 1-week follow-up, the steroid group had significantly better improvement than the PRP group (p=0.0001). At the 3-week follow-up, both groups showed comparable outcomes; however, the PRP group had better symptom improvement. At 6 weeks and 6 months, the PRP group had better outcomes (VAS, p<0.0001; ODI, p=0.02; SF-12, p=0.002). Moreover, 17 and 16 patients in the steroid and PRP groups underwent repeat LTI with steroids or surgery because of pain recurrence during follow-up. At 1 year, no difference in outcomes was observed. @*Conclusions@#PRP may be a useful alternative to steroids for LTI in lumbar radiculopathy. Although improvement was delayed and 1-year outcomes were comparable, the 6-week and 6-month outcomes were better with PRP than with LTI. Multiple PRP injections may be beneficial because of its autologous nature. However, further studies with a larger number of participants, longer follow-up, and repeat LTIs are warranted to draw definite conclusions.
RÉSUMÉ
Methods@#Using the hospital records and imaging database obtained from January 2014 to January 2020, this study retrospectively analyzed patients who underwent surgery for Pott’s spine and met the eligibility criteria. @*Results@#This study included 230 patients with a mean±standard deviation age of 47.7±18.1 years (109 males, 121 females). The Visual Analog Scale score, Oswestry Disability Index, and Cobb angle were significantly improved in these patients (p<0.001). Patients who underwent anterior reconstruction had a greater correction in Cobb angle postoperatively (p=0.042) but also had a greater blood loss (p=0.04). During the follow-up, they experienced a significant loss of correction compared with those who only underwent transpedicular decompression (p=0.026). Nevertheless, patients who underwent anterior reconstruction using mesh/PEEK cages showed no significance difference in the clinical or radiological outcomes. @*Conclusions@#Transpedicular decompression used in the surgical management of Pott’s spine showed favorable clinical and radiological outcomes. The additional use of anterior reconstruction obtained equivalent clinical outcomes but resulted in excessive blood loss. Meanwhile, the use of mesh/PEEK cage for anterior reconstruction did not affect the clinical and radiological outcomes.
