ABSTRACT
OBJECTIVE@#To investigate the effect of modified alternate negative pressure drainage on postoperative outcomes after posterior lumbar interbody fusion (PLIF) surgery.@*METHODS@#This was a prospective study involving 84 patients who underwent PLIF surgery between January 2019 and June 2020. Of these patients, 22 had single-segment surgery and 62 had two-segment surgery. Patients were grouped by surgical segment and admission sequence:the observation group included patients with a single-segment surgery, and the control group included patients with a two-segment surgery. Natural pressure drainage was given to 42 patients in the observation group (modified alternate negative pressure drainage group) after surgery, which was then changed to negative pressure drainage after 24 hours. In the control group, 42 patients were given negative pressure drainage after surgery, which was then changed to natural pressure drainage after 24 hours. The total drainage volume, drainage time, maximum body temperature at 24 hours and 1 week after surgery, and drainage-related complications were observed and compared between the two groups.@*RESULTS@#There was no significant difference in operative time and intraoperative blood loss between the two groups. The postoperative total drainage volume was significantly lower in the observation group (456.69±124.50) ml than in control group (572.36±117.75) ml, and the drainage time was significantly shorter in the observation group (4.95±1.31) days than in the control group (4.00±1.17) days. Maximum body temperature at 24 hours after surgery was similar in both groups (37.09±0.31)°C in the observation group and (37.03±0.33)°C in the control group, while on the 1st week after surgery, it was slightly higher in the observation group (37.05±0.32)°C than in the control group (36.94±0.33)°C, but the difference was not significant. There were no significant differences in drainage-related complications, with one case(2.38%) of superficial wound infection in the observation group and two cases(4.76%) in control group.@*CONCLUSION@#Modified alternate negative pressure drainage after posterior lumbar fusion can reduce the drainage volume and shorten the drainage time without increasing the risk of drainage-related complications.

Background: Many different treatment modalities have been advocated by different authors from time to time for lumbarspondylolisthesis. Many cases, the condition can be treated conservatively. However, when the symptoms persist, surgeryneeds to be performed. The principle of underlying surgery includes stabilization of the slipping vertebrae. Various operativemethods encompassing this principle include stabilization with pedicle screw fixation and fusion which can either posterolateralor interbody fusion, anterior lumbar interbody fusion, posterior lumbar interbody fusion, or transforaminal lumbar interbodyfusion. The objective of this study was to compare the surgical efficacy in terms of stability and fusion achieved using pediclescrew-rod instrumentation with posterolateral fusion and pedicle screw-rod instrumentation with interbody fusion in lumbarspondylolisthesis and to study THE functional and clinical recovery using the Revised Oswestry Disability Index score.Materials and Methods: A prospective study was carried out to compare the clinical and radiological outcomes between Pediclescrew-rod instrumentation with either posterolateral fusion and interbody fusion after adequate decompression in patient oflumbar spondylolisthesis. All patients as per the inclusion criteria were admitted, underwent surgery between March 2010 andMarch 2012, and were included in the study.Results: The total of 50 patients was included in our study. Both male and female patients were equally distributed in both thegroups, wherein postreolateral fusion had 13 female patients and those with interbody fusion had 13 male patients. Our studyshows marked improvement in Revised Oswestry Disability score postoperatively with good-to-excellent results in both thegroups. We achieved good solid radiological fusion earliest on the 3rd month in both the groups with good stability.Conclusion: Our results showed similar clinical and functional outcome in both the groups with no significant statistical differencefound. However, we conclude that in cases where reduction is required and there is instability affecting the three column ofspine interbody fusions with pedicle screws-rod instrumentation provide a more solid mechanical construct.
ABSTRACT
OBJECTIVE:To observe analgesic efficacy of oxycodone acetaminophen after posterior lumbar fusion,and to opti-mize spinal postoperative analgesia plan. METHODS:In retrospective study,120 patients underwent posterior lumbar fusion were selected from the Affiliated People's Hospital of Hubei Medical College during Jun. 2013-Jun. 2014,and then divided into observa-tion group and control group according to therapy plan,with 60 cases in each group. Observation group was given oxycodone acet-aminophen 330 mg orally 6 h after surgery,and then 330 mg orally on 1st,2nd day after surgery,tid. Control group was given celecoxib 200 mg 6 h after surgery,and then 200 mg on 1st,2nd day after surgery,bid. Postoperative analgesic efficacy (VAS score) at resting state and active state,postoperative gastrointestinal motility recovery (the time to flatus) and the occurrence of ADR were observed in 2 groups after surgery. RESULTS:Whether at the resting state or the active state 24,48,72,120 h after surgery,VAS score of observation group was significantly lower than that of control group,with statistical significance(P0.05). CONCLUSIONS:Oral administration of oxycodone acetaminophen possesses good effect to relieve spinal postoperative pain,showing fast and safe analgesic efficacy.
ABSTRACT
Objective To compare the analgesia effect and the safety of Flurbiprofen Axetil (FA) and Parecoxib Sodium (PS) after posterior lumbar fusion surgery. Methods 90 patients undergoing internal fixation of lumbar spine randomly assigned to 3 groups:those in Group A(n = 30) received 100 mg of FA; those in Group B (n=30) received 40 mg of PS and those in Group C received saline.The VAS scores of 2, 6, 12, 24, 48, 72 h after operation and the dose of tramadol hydrochloride (TH) used and the side effect was recorded respectively. Results Group A and B had significantly better analgesic effect than Group C(P<0.05). Group A and B had lower average dose of TH than Group C (P<0.05). The VAS scores in Group A was lower than that in Group B in 2 h after the surgery. The VAS scores after the surgery showed no significant difference between Group A and B in 6 , 12, 24 h after the surgery. The VAS scores in Group A was higer than that in Group B in 48,72 h after the surgery. Conclusion Both PS and FA can alleviate postoperative pain and have fewer adverse reactions.
ABSTRACT
The purpose of this study was to compare patients with lumbar spondylolisthesis submitted to two different surgical approaches, and evaluate the results and outcomes in both groups. In a two-year period, 60 adult patients with lumbar spondylolisthesis, both isthmic and degenerative, were submitted to surgery at the Biocor Institute, Brazil. All patients were operated on by the same surgeon (FLRD) in a single institution, and the results were analyzed prospectively. Group I comprised the first 30 consecutive patients that were submitted to a posterior lumbar spinal fusion with pedicle screws (PLF). Group II comprised the last 30 consecutive patients submitted to a posterior lumbar interbody fusion procedure (PLIF) with pedicle screws. All patients underwent foraminotomy for nerve root decompression. Clinical evaluation was carried out using the Prolo Economic and Functional Scale and the Rolland-Morris and the Oswestry questionnaire. Mean age was 52.4 for Group I (PLF), and 47.6 for Group II (PLIF). The mean follow-up was 3.2 years. Both surgical procedures were effective. The PLIF with pedicle screws group presented better clinical outcomes. Group I presented more complications when compared with Group II. Group II presented better results as indicated in the Prolo Economic and Functional Scale.
O objetivo foi comparar dois grupos de pacientes portadores de espondilolistese lombar que foram submetidos a dois procedimentos cirúrgicos distintos, avaliando os resultados clínicos levando em consideração a qualidade de vida. Durante o período de 1998 a 2001 sessenta pacientes portadores de espondilolistese da coluna lombar ístmica e degenerativa foram submetidos a tratamento cirúrgico no Hospital Biocor em Belo Horizonte, por um mesmo cirurgião foram analisados prospectivamente. Os primeiros trinta pacientes foram submetidos a fusão posterior com parafusos pediculares e os trinta seguintes a fusão posterior com parafusos pediculares associada a fusão intersomática posterior. Os pacientes foram submetidos a liberação radicular com laminectomia e foraminotomia. A avaliação clínica foi feita utilizando as escalas de Prolo Econômico e Funcional, o questionário de Rolland-Morris e de Oswestry. Os resultados clínicos apresentaram que os dois procedimentos realizados foram eficazes. Houve maior número de complicações relacionadas com a biomecânica no grupo que foi submetido somente à fusão posterior e o grupo submetido à fusão posterior associada a fusão intersomática apresentou melhores resultados com retorno as atividades diárias e melhora da qualidade de vida.
