Lumbar disc herniation was treated by percutaneous discectomy using a new instrument for automatic aspiration and cutting of disc material. The inclusion criteria were limited to patients with pure disc herniation without stenosis or any other additional factors. Only contained hernias with a maximum size of 50% of the thecal sac were included. Three procedures out of 45 were technical failures. At 1-year follow-up 69% of the patients were satisfied. No complications were seen. The result was not influenced by the amount of disc material removed, age, duration of symptoms or the size of the disc hernia. Reduced size of disc hernia was found in 13 out of 14 satisfied patients followed by CT. All unsatisfied patients were conventionally operated on. The percutaneous treated patients had 1 day of hospitalisation and on average 11 weeks of sick-leave compared to an average of 6 days and 16 weeks following conventional discectomy.

OBJECTIVELumbar disc herniation (LDH) in the pediatric population is rare and exhibits unique characteristics compared with adult LDH. There are limited data regarding the safety and efficacy of minimally invasive surgery (MIS) using tubular retractors in pediatric patients with LDH. Here, the outcomes of MIS tubular microdiscectomy for the treatment of pediatric LDH are evaluated.METHODSTwelve consecutive pediatric patients with LDH were treated with MIS tubular microdiscectomy at the authors’ institution between July 2011 and October 2015. Data were gathered from retrospective chart review and from mail or electronic questionnaires. The Macnab criteria and the Oswestry Disability Index (ODI) were used for outcome measurements.RESULTSThe mean age at surgery was 17 ± 1.6 years (range 13–19 years). Seven patients were female (58%). Prior to surgical intervention, 100% of patients underwent conservative treatment, and 50% had epidural steroid injections. Preoperative low-back and leg pain, positive straight leg raise, and myotomal leg weakness were noted in 100%, 83%, and 67% of patients, respectively. The median duration of symptoms prior to surgery was 9 months (range 1–36 months). The LDH level was L5–S1 in 75% of patients and L4–5 in 25%. The mean ± SD operative time was 90 ± 21 minutes, the estimated blood loss was ≤ 25 ml in 92% of patients (maximum 50 ml), and no intraoperative or postoperative complications were noted at 30 days. The median hospital length of stay was 1 day (range 0–3 days). The median follow-up duration was 2.2 years (range 0–5.8 years). One patient experienced reherniation at 18 months after the initial operation and required a second same-level MIS tubular microdiscectomy to achieve resolution of symptoms. Of the 11 patients seen for follow-up, 10 patients (91%) reported excellent or good satisfaction according to the Macnab criteria at the last follow-up. Only 1 patient reported a fair level of satisfaction by using the same criteria. Seven patients completed an ODI evaluation at the last follow-up. For these 7 patients, the mean ODI low-back pain score was 19.7% (SEM 2.8%).CONCLUSIONSTo the authors’ knowledge, this is the longest outcomes study and the largest series of pediatric patients with LDH who were treated with MIS microdiscectomy using tubular retractors. These data suggest that MIS tubular microdiscectomy is safe and efficacious for pediatric LDH. Larger prospective cohort studies with longer follow-up are needed to better evaluate the long-term efficacy of MIS tubular microdiscectomy versus other open and MIS techniques for the treatment of pediatric LDH.

Background Outcome of lumbar disc herniation are influenced by various clinical, socioeconomic and psychological factors. In the absence of provision of medical insurances, worker’s compensation and sick leave, predictors for outcome after lumbar disc herniation surgery will be different in Nepalese population.Objective To evaluate different clinical variables that can affect outcome after lumbar disc herniation surgery.Method Among 88 patients who underwent microdisectomy for lumbar disc herniation, 63 patients (43 male, 20 female) with follow up at least six months were retrospectively evaluated for clinical variables which can affect Oswestry disability index (ODI) score, its interpretation and Mcnab classification of post operative outcome.Result Average age of patients was 42.54±8.60 years. Mean follow up period was 34.89±23.80 months (range 6 -111 months). Thirty four patients had follow up period > 24 months. Mean ODI score before surgery and at final follow up was 37.87±8.76 vs 7.78±7.7; (p=0.00). Success rate was 90.47% (change in ODI score at least by 10), 93.65% (ODI score interpretation <40%), and 85.71%. (Mcnab outcome excellent and good). Significant correlation was found between age and ODI at final follow up but not with duration of symptoms. Male, non alcoholic, low level of education, numbness as a predominant symptom, disc at L4-L5 were significantly associated with better ODI at final follow up. For ODI score interpretation, gender, smoking habit, presence of leg pain as a predominant symptom were statistically significant factors whereas smoking and drinking habit, level of education, occupation, back pain and numbness as predominant pre-operative symptom, types of disc in MRI were significantly related to Mcnab outcome. There was 9.5% peri- or post-operative complications and recurrence in seven patients.Conclusion Age, gender, smoking and drinking habit, level of education, occupation, types of disc in MRI are important variables for ODI score, ODI score interpretation and Mcnab outcome.

Abstract Objective This retrospective observational histological study aims to associate the size and type of disc herniation with the degree of macrophage infiltration in disc material retrieved during disc surgery in patients with sciatica. Methods Disc tissue of 119 sciatica patients was embedded in paraffin and stained with hematoxylin and CD68. Tissue samples were categorized as mild (0–10/cm2), moderate (10–100/cm2), and considerable (> 100/cm2) macrophage infiltration. All 119 patients received an MRI at baseline, and 108 received a follow-up MRI at 1-year. MRIs were reviewed for the size and type of the disc herniations, and for Modic changes in the vertebral endplates. Results Baseline characteristics and duration of symptoms before surgery were comparable in all macrophage infiltration groups. The degree of macrophage infiltration was not associated with herniation size at baseline, but significantly associated with reduction of size of the herniated disc at 1-year post surgery. Moreover, the degree of macrophage infiltration was higher in extrusion in comparison with bulging (protrusion) of the disc. Results were comparable in patients with and without Modic changes. Conclusion Macrophage infiltration was positively associated with an extruded type of disc herniation as well as the extent of reduction of the herniated disc during 1-year follow-up in patients with sciatica. This is an indication that the macrophages play an active role in reducing herniated discs. An extruded disc herniation has a larger surface for the macrophages to adhere to, which leads to more size reduction.

Daugeliu atvejų tarpslankstelinio disko išvaržos sukeltų simptomų natūrali eiga yra gerybinė dėl disko išvaržos spontaninės rezorbcijos. Dauguma disko išvaržas turinčių pacientų sveiksta taikant konservatyvų gydymą. Jei konservatyvus gydymas nesukelia pagerėjimo, pacientus tenka operuoti. Šiame straipsnyje pristatomas naujas Lietuvoje disko išvaržos chirurginio gydymo būdas – perkutaninė lazerinė disko dekompresija (PLDD). Pacientai ir metodai Nuo 2007 m. gegužės iki 2009 m. birželio 20 pacientų atrinkta PLDD operacijai. Skausmo intensyvumas prieš operaciją įvertintas pagal VAS (Visual Assessment Analogue Scale) skalę, gyvenimo kokybė ir neįgalumo laipsnis – pagal ODI (Oswestry Disability Index) klausimyną. VAS skausmo indeksas prieš operaciją buvo nuo 3 iki 7 balų esant ramybės būsenos (vid. – 5,0), judesio metu – nuo 5 iki 9 balų (vid. – 6,75). ODI neįgalumo indeksas nuo 20% iki 60% (vid. – 47,5%). Atliktos 24 PLDD operacijos, naudota vietinė nejautra ir rentgenoskopo kontrolė. Pooperacinis įvertinimas atliktas praėjus 2 ir 6 mėn. po operacijos. Rezultatai Geras, ilgai trunkantis efektas buvo 14 pacientų (70%). Po 6 mėn. – VAS esant ramybės būsenos svyravo nuo 1 iki 5 (vid. – 1,75), judesio metu nuo 1 iki 7 balų (vid. – 2,6). Vidutinis VAS kritimas: esant ramybės būsenos – 3,25; judesio metu – 4,15. ODI po 6 mėn. nuo 2% iki 48% (vid. ODI – 18,8%); vidutinis ODI kritimas – 28,7%. Išvados Disko išvaržos chirurginio gydymo kriterijai galutinai nėra nustatyti, tebevyksta diskusija apie chirurginio gydymo privalumus ir trūkumus. Disko išvaržos chirurginis gydymas sukelia greitesnį simptomų regresą, po jo greitesnė reabilitacija, greičiau pavyksta atkurti darbingumą, bet yra vėlyvų komplikacijų rizika. Perkutaninė lazerinė disko dekompresija pastaruoju metu pripažįstama esanti efektyvus, minimaliai invazyvus chirurginis disko išvaržos gydymo būdas, taikytinas kai kurioms disko išvaržoms. Atvira disko išvaržos operacija (mikrodiskektomija) ir PLDD neturėtų būti vertinami kaip du alternatyvūs metodai gydyti tą patį pacientą, nes įtraukimo PLDD ir atvirai operacijai kriterijai skiriasi. Gydymo metodo pasirinkimą lemia išvaržos morfologija, nustatoma MRT tyrimu. Abu metodai turėtų būti prieinami ir gyvuoti greta ligoninėse, kur operuojama stuburo patologija. Ligoniai, turintys disko sekvestrą, pratrūkusią disko išvaržą ar masyvią subligamentinę disko išvaržą, turėtų būti operuojami atvira operacija; ligoniai, kurių disko išvarža nepratrūkusi, nesukelia didelės nervinės šaknelės kompresijos, turėtų būti operuojami minimaliai invaziniais intradiskiniais metodais (PLDD).

The natural course of lumbar disc hernia-induced symptoms is benign in many cases because of spontaneous resorption of herniated nucleus pulposus. It is well known that the majority of LDH patients recover spontaneously; others will require surgery after failure of conservative treatment. Here we present new in Lithuania surgical treatment method for intervertebral disc hernia- Percutaneous Laser Disc Decompression (PLDD). Material and Methods During the period from 2007 May to 2009 June, 20 patients have been selected to be operated on disc herniation by means of Percutaneous Laser Disc Decompression (PLDD). All patients preoperatively were evaluated by Visual Assessment Analogue Scale (VAS) and Oswestry Disability Index (ODI). VAS pain index preoperatively ranged from 3 to 7 points at rest (mean- 5.0 points), to 5-9 points at movement (mean-6.75 points). ODI preoperatively ranged from 20% to 60% (mean 47.5%). 24 PLDD procedures were performed under local anesthesia, using C-arm control. Post operative evaluation was made at 2 and 6 months. Results 14 patients (70%) experienced long lasting relief of their symptoms. At 6 month follow-up VAS score ranged from 1 to 5 at rest (mean 1.75), at movement range was from 1 to 7 (mean 2.6 points). Mean VAS drop was 3.25 points at resting state, and 4.15 points at movement. ODI at 6 month follow-up ranged from 2% to 48%, mean being 18.8%. Mean ODI drop was 28.7%. Conclusions There is ongoing discussion about disc herniation surgery. Surgical treatment provides faster rehabilitation and faster decrease of symptoms, but has a certain danger of late complications. Percutaneous Laser Disc Decompression (PLDD) has been recently accepted as effective surgical intervention on certain types of disc herniation. Open microdiscectomy and PLDD should not be compared as two different ways of treating the same patient because inclusion criteria for both methods differ due to morphology of disc herniation on MRI. Patients having sequestration, transligamentous or extensive subligamentous extrusion should go for open surgery; patients having moderate or mild protrusion of intervertebral disc with no obvious compression of nerve roots should go for PLDD. Key words: Intervertebral disc hernia, low back pain, laser surgery

OBJECT The aim of this paper was to investigate the risk of recurrence of lumbar disc herniation (LDH) in patients with scoliosis who underwent microdiscectomy. METHODS A series of consecutive patients who underwent microdiscectomy for LDH was retrospectively reviewed. The inclusion criteria were young adults younger than 40 years who received microdiscectomy for symptomatic 1-level LDH. An exclusion criterion was any previous spinal surgery, including fusion or correction of scoliosis. The patients were divided into 2 groups: those with scoliosis and those without scoliosis. The demographic data in the 2 groups were similar. All medical records and clinical and radiological evaluations were reviewed. RESULTS A total of 58 patients who underwent 1-level microdiscectomy for LDH were analyzed. During the mean follow-up of 24.6 months, 6 patients (10.3%) experienced a recurrence of LDH with variable symptoms. The recurrence rate was significantly higher among the scoliosis group than the nonscoliosis group (33.3% vs 2.3%, p = 0.001). Furthermore, the recurrence-free interval in the scoliosis group was short. CONCLUSIONS Young adults (< 40 years) with uncorrected scoliosis are at higher risk of recurrent LDH after microdiscectomy.

The purpose of this study is to identify some risk factors and post-operative predictors for recurrent lumbar disc hernia (rLDH) during a long-term follow-up in patients treated with microdiscectomy. Aim of the paper: This study analyzes some risk factors and postoperative predictors for recurrent lumbar disc hernia (rLDH) during a long-term follow-up in patients treated with microdiscectomy. Material and methods. We analyzed retrospectively a consecutive series of patients who underwent lumbar spinal microdiscectomy for lumbar disc herniation (LDH) from January 2013 to June 2018 at our Institute. The rate of rLDH during long-term follow-up was analyzed and correlated with baseline and post-operative data. Results. A total of 263 patients were included with a median follow-up time of 24 months (from 13 to 43 months). Most of the patients had rLDH within the first 36 months after surgery. At multivariate analysis, recurrence of LDH was associated with higher pre-operative body mass index (BMI) and higher post-operative Oswentry disability index (ODI) with statistical significance. Conclusions. Baseline BMI and post-surgery ODI could predict rLDH after surgery during a long-term follow-up.

OBJECTIVEThe authors sought to investigate the efficiency of percutaneous endoscopic discectomy (PED) in adolescent patients with lumbar disc herniation (LDH), compare PED outcomes in adolescent patients with those in young adult LDH patients as controls, and discuss relevant technical notes.METHODSThis was a retrospective study involving 19 adolescent LDH patients (age > 13 and < 18 years, 20 discectomies) and 38 young adults (age < 40 years, 38 discectomies) who also had LDH and were matched to the adolescent group for sex and body mass index. The combined cohort included 51 male patients (89.5%) and 6 female patients (10.5%), with an average age of 26.7 years (range 14–39 years). The operated levels included L3–4 in 1 patient (1.7%), L4–5 in 22 patients (37.9%), and L5–S1 in 35 patients (60.4%). Two adolescents (10.5%) exhibited apophyseal ring separation and one (5.3%) had had previous PED. All patients underwent PED under local anesthesia. Outcomes were evaluated through a visual analog scale (VAS), the Japanese Orthopaedic Association (JOA) scoring system, and the modified MacNab grading system.RESULTSThe mean duration of follow-up was 41.7 months (range 36–65 months). The outcomes in adolescents were satisfactory and comparable with previously reported outcomes of microsurgical discectomy (MD) and conventional open discectomy (COD). The adolescent patients had a faster and better recovery course than the adult patients (p < 0.01). One adolescent patient (5.3%) exhibited recurrence and 2 adults (5.3%) experienced transient dysesthesia; the complication rates were comparable in the 2 age groups (p = 0.47). Prolonged duration of symptoms (p < 0.01) and disc degeneration (p = 0.01) were correlated with lower postoperative JOA values; patients with extrusions had higher postoperative JOA values than those with protrusions (p = 0.01).CONCLUSIONSPED may yield favorable results in the treatment of adolescent LDH in terms of short- to medium-term follow-up; restricted discectomy and a conservative rehabilitation program might be advisable. Further long-term studies are warranted to address this rare disease entity.

Object. The aim of this study was to investigate different variables in the duration of symptoms that can be used to predict outcome after lumbar microdiscectomy. Methods. In a prospective study of 132 consecutive patients who underwent surgery for lumbar disc herniation, the authors evaluated the prognostic value of different variables in the duration of symptoms for the 1-year period after surgery. The 1-year follow-up investigation was conducted by an independent observer. Assessment of outcome was performed using a clinical overall score (COS), which was recently assessed for its reliability and validity. As for factors predictive of outcome, only duration of leg pain and sick leave reached statistical significance in the multivariate analysis. Results of the univariate analysis demonstrated that in patients experiencing preoperative leg pain fewer than 4 months and between 4 and 8 months, a significantly lower COS at the 1-year follow up was demonstrated compared with those in whom the duration of leg pain was longer (> 8 months). One hundred eight patients returned to work within the 1st year after surgery. Patients who took a sick leave of more than 28 weeks before the operation were at higher risk of not returning to work. Conclusions. Analysis of these results indicates that leg pain lasting more than 8 months correlates with an unfavorable postoperative outcome in patients with lumbar disc herniation, as well as a high risk of not returning to work.

Abstract Background The area which located at the medial pedicle, posterior vertebral body and ventral hemilamina is defined as the hidden zone. Surgical management of hidden zone lumbar disc herniation (HZLDH) is technically challenging due to its difficult surgical exposure. The conventional interlaminar approach harbors the potential risk of post-surgical instability, while other approaches consist of complicated procedures with a steep learning curve and prolonged operation time. Objective To introduce microscopic extra-laminar sequestrectomy (MELS) technique for treatment of hidden zone lumbar disc herniation and present clinical outcomes. Methods Between Jan 2016 to Jan 2018, twenty one patients (13 males) with HZLDH were enrolled in this study. All patients underwent MELS (19 patients underwent sequestrectomy only, 2 patients underwent an additional inferior discectomy). The nerve root and fragment were visually exposed using MELS. The operation duration, blood loss, intra- and postoperative complications, and recurrences were recorded. The Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the modified MacNab criteria were used to evaluate clinical outcomes. Postoperative stability was evaluated both radiologically and clinically. Results The mean follow-up period was 20.95 ± 2.09 (18–24) months. The mean operation time was 32.43 ± 7.19 min and the mean blood loss was 25.52 ± 5.37 ml. All patients showed complete neurological symptom relief after surgery. The VAS and ODI score were significantly improved at the final follow-up compared to those before operation (7.88 ± 0.70 vs 0.10 ± 0.30, 59.24 ± 10.83 vs 11.29 ± 3.59, respectively, p < 0.05). Seventeen patients (81%) obtained an “excellent” outcome and the remaining four (19%) patients obtained a “good” outcome based the MacNab criteria. One patient suffered reherniation at the same level one year after the initial surgery and underwent a transforaminal endoscopic discectomy. No major complications and postoperative instability were observed. Conclusions Our observation suggest that MELS is safe and effective in the management of HZLDH. Due to its relative simplicity, it comprises a flat surgical learning curve and shorter operation duration, and overall results in reduced disturbance to lumbar stability.
