STUDY DESIGN: Prospective cohort study along with questionnaire. PURPOSE: To measure the correlation of the visual analogue score (VAS), with (Oswestry disability Index [ODI], version 2.1a) in English, and modified ODI (English and Hindi version). To validate translated version of the modified ODI in English version to Hindi. OVERVIEW OF LITERATURE: Conflicting evidence in literature regarding the ability for existing ODI score to accurately measure the pain associated disability. METHODS: One hundred and three patients conservatively treated for low back pain were enrolled in the study. The Pearson correlation coefficient for VAS and ODI along with the Cronbach alpha and test-retest reliability for Hindi version using the intraclass correlation coefficient was recorded. The new proposed translated Hindi version of ODI was carried out with established guidelines. RESULTS: The mean age in English and Hindi version of ODI was 53.5 years and 58.5 years, respectively. The gender ration was 21:24 in the English version and 35:23 in the Hindi version. The mean follow-up in English and Hindi version of ODI was 3.4 months and 50.27 months, respectively. The Cronbach coefficient alpha=0.7541 for English ODI and 0.9913 for Hindi ODI was recorded for the both modified versions. CONCLUSIONS: The new modified ODI is time saving and accurate, and it avoids the need to measure other scores and has stronger correlation with VAS score compared to the previous scores. We recommend this version for both English and Hindi speaking population as an assessment tool to measure the disability related to pain.

STUDY DESIGN: Prospective cohort study with questionnaire. PURPOSE: To compare the treatment outcome of nocturnal leg cramps in lumbar spinal canal stenosis (LSCS) patients on conservative treatment with historical surgical cohorts and to determine the sensitivity and specificity as well as positive predictive value and negative predictive value of knee flexion test suggested for LSCS patient. OVERVIEW OF LITERATURE: True prevalence of nocturnal leg cramps in LSCS patients as well as the clinical outcome of its surgical treatment have been reported. METHODS: A questionnaire suggested from previous study with minor modifications was used in this study. Clinical data was collected. Knee flexion test was performed in two groups. RESULTS: The prevalence of nocturnal leg cramp was higher in the LSCS group compared to the control group (second group). In LSCS patients, 38 (88%) had improved leg cramps after the conservative treatment, 3 (6.97%) remained unchanged, and 2 (4.6%) had worsened leg cramps. Of the 43 patients, 21 (48.8%) had no disturbance to their activities of daily living. In the LSCS group, the sensitivity and specificity of the knee flexion test was 53.5% and 33.3%, respectively. The knee flexion test in the LSCS group had a positive predictive value and a negative predictive value of 65.71% and 23.1%, respectively. CONCLUSIONS: Our study demonstrated that nocturnal leg cramps were significantly more frequent in LSCS patients than in the control group.

Methods: The clinical records of 953 patients who were operated between 1998 and 2008 were analyzed in 2018. Along with patient characteristics, information about return to daily activities, complication rates, and functional outcomes using Prolo score was assessed. Results: L4–L5 was the most common level for which surgery was performed. Two-level decompression was performed in 116 patients; 89.5% patients were able to return to their daily activities after 2 weeks. Functional outcomes as per the Prolo score were reported by patients as excellent, good, and poor in 89.85%, 1.59%, and 8.55%, respectively. Repeat surgery was required at same level in 16 patients and at a different level in 21 patients. Total 605 patients (63.49%) were symptom-free during the 70-month followup, while 344 complained of residual back pain, and four complained of persistent leg pain. Conclusions ULBD using the Endospine system achieves adequate decompression in most cases and is a good alternative to open laminectomy, with the advantage of avoiding damage to the structural integrity of the spine and preserving soft tissue attachments.

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.

Methods: All cases of cauda equine syndrome secondary to lumbar disc herniation were recruited. Biographical and clinical data, history, examination findings, operative variables, recovery, and SD were noted. Water cystometry and uroflowmetry were done pre- and postoperatively. The International Index of Erectile Function questionnaire and Female Sexual Function Index were used to assess SD among the men and women, respectively. Results: A total of 43 patients with up to 2.94-year follow-up were included. Urodynamic studies were found to correlate significantly with age, days of bladder involvement, perianal numbness, and motor weakness (p<0.01). In step-wise regression analysis, perianal sensation and overall motor weakness were bladder function determinants. Bladder function recovery was directly related to the number of delay days (t=2.30, p<0.05) and with unilateral leg pain (t=2.15, p<0.05). Significant correlation between SD with age and days of bladder involvement before surgery was found (p<0.01). Conclusions Surgery timing is related to patient’s functional and sexual outcomes. Patients with unilateral leg pain and hypocontractile bladder have better outcomes. SD is a remarkable problem in CES.

STUDY DESIGN: Retrospective study. PURPOSE: The aim of this study was to analyze various diagnostic tools, including GeneXpert, for the management of tuberculosis of the spine. OVERVIEW OF LITERATURE: Traditional diagnostic methods of microscopy, histology, and culture have low sensitivity and specificity for the management of tuberculosis of the spine. METHODS: Of the 262 treated cases of spinal tuberculosis, data on 1 year follow-up was available for 217 cases. Of these, only 145 cases with a confirmed diagnosis were selected for retrospective analysis. RESULTS: In 145 of the 217 patients (66.80%), diagnosis was confirmed on the basis of a culture. Of the 145 patients with a confirmed diagnosis, 98 (66.20%) patients were diagnosed on the basis of clinical presentation, whereas 123 (84.8%) exhibited a typical magnetic resonance imaging (MRI) picture. In 99 surgically treated patients, the diagnosis was confirmed on the basis of an intraoperative tissue biopsy. Among the 46 patients treated conservatively, 35 underwent a transpedicular biopsy, 4 patients underwent computed tomography-guided biopsy, 6 patients were diagnosed on the basis of material obtained from a cold abscess, and 1 patient underwent an open biopsy. The sensitivity of the culture for the detection of Mycobacterium tuberculosis was 66.80% (145/217) in our patients. Among the cases in which GeneXpert was used, the sensitivity for the detection of Mycobacterium tuberculosis was 93.4% (43/46). Moreover, the sensitivity of GeneXpert to detect rifampicin resistance was 100% (7/7) in our study. CONCLUSIONS: Majority of the patients with tuberculosis of the spine can be diagnosed on the basis of a typical radiological presentation via MRI. In our study, 84.8% cases exhibited typical MRI findings. For patients presenting with atypical MRI features, a rapid and accurate diagnosis is possible by combining GeneXpert with MRI. The combined use of MRI and GeneXpert is a rapid and highly sensitive tool to diagnose tuberculosis and rifampicin resistance in patients with tuberculosis of the spine. Furthermore, we achieved a 97.9% sensitivity for the detection of Mycobacterium tuberculosis and 100% sensitivity for the detection of rifampicin resistance in our study.

STUDY DESIGN: A retrospective computed tomography (CT)-based morphometric study of 82 occipital condyles in the Indian population, focusing on critical morphometric dimensions with relation to placing condylar screws. PURPOSE: This study focused on determining the feasibility of placing occipital condylar screws in an Indian population using CT anatomical morphometric data. OVERVIEW OF LITERATURE: The occipital condylar screw is a novel technique being explored as one of the options in occipitocervical stabilization. Sex and ethnic variations in anatomical structures may restrict the feasibility of this technique in some populations. To the best of our knowledge, there are no CT-based data on an Indian population that assess the feasibility of occipital condylar screws. METHODS: We measured the dimensions of 82 occipital condyles in 41 adults on coronal, sagittal, and axial reconstructed CT images. The differences were noted between the right and left sides and also between males and females. Statistical analysis was performed using the t-test, with a p-value of < 0.05 considered significant. RESULTS: Mean sagittal length and height were 17.2±1.7 mm and 9.1±1.5 mm, respectively. Mean condylar angle/screw angle was 38.0°±5.5° from midline, with mean condylar length and width of 19.6±2.6 mm and 9.5±1.0 mm, respectively. Average coronal height on the anterior and posterior hypoglossal canal was 10.8±1.4 mm and 9.0±1.4 mm, respectively. The values in females were significantly lower than those in males, except for screw angle and condylar width. Based on Lin et al.'s proposed criteria, eight of 82 condyles were not suitable for condylar screws. CONCLUSIONS: Preliminary CT morphometry data of the occipital condyle shows that condylar screws are anatomically feasible in a large portion of the Indian population. However, because a small number of population may not be suitable for this technique, meticulous study of preoperative anatomy using detailed CT data is advised.
