Study Design: Systematic review. Objectives: (1) Study indications for cement-augmented pedicle screws (CAPS) in patients with osteoporosis. Have they changed over the years (2000-2017)? Are there any differences in usage of CAPS based on the geographical region? (2) What were the outcome of the studies? (3) What are the complications associated with this technique? Methods: Electronic database and reference list of desired articles were searched from the database (2000-2017). Articles were selected discussing indications, clinical and radiological outcomes, and complications in cases of preexistent osteoporosis treated surgically using CAPS. Results: Seventeen studies were identified; 3 were comparative studies and had a control arm (cemented vs noncemented screws). Most studies originated from Europe (10) or Asia (7). Painful vertebral fracture with or without neurological deficit, Kummell’s lesion, deformity and failure to respond to conservative treatment are the common indications for cement augmentation. Visual analogue scale score was the most commonly used to assess pain and average improvement after surgery was 6.1. Average improvement in kyphosis was 13.21° and average loss of correction at the end of the study was 3°. Cement leak was the most common complication observed and pulmonary cement embolism was the most dreaded complication. Nevertheless, majority of cement leaks discussed in studies were asymptomatic. Conclusion: CAPS are being increasingly used in osteoporotic spine. Pain scores, functional quality of life, and neurological function indices were studied. CAPS improved anchorage in osteoporotic vertebra and helped improve/maintain clinical and radiological improvement. Common risks of cement leak were observed.

In management of patients suffering from tuberculosis of spine, levels of vertebral involvement, AIS grade at presentation, bladder and bowel involvement and its duration significantly affect the final neurological improvement.

Study DesignRetrospective study.PurposeThe aim of this study was to analyze various diagnostic tools, including GeneXpert, for the management of tuberculosis of the spine.Overview of LiteratureTraditional diagnostic methods of microscopy, histology, and culture have low sensitivity and specificity for the management of tuberculosis of the spine.MethodsOf 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.ResultsIn 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.ConclusionsMajority 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: Retrospective study. Objective: The purpose of the study was to analyze the epidemiological parameters and associated factors after spinal cord injury (SCI) in children, in the last 14 years admitted at a tertiary care center (Indian Spinal Injury Centre [ISIC], New Delhi, India). Method: The demographic and injury-related data was analyzed descriptively. The incidence, type, and level of injury were compared across the age groups using a χ2 test. Wherever appropriate, Fisher exact test was used. Results: There were 1660 pediatric trauma cases admitted at ISIC from 2002 to 2015, where 204 cases presented with spine injuries. The average age of children sustaining spine injury was 15.69 years (3-18 years of range). There were 15 patients in the age group 0 to 9 years, 27 patients in the age group 10 to 14 years, and 162 patients in the age group 15 to 18 years. This difference in spine injury incidence among the age groups was statistically significant. Fall from height was a common mode of injury. In our sample, boys were 3 times more likely to be injured than girls. Burst fractures were common among the type of injuries. Conclusion: Our study confirms the predominance of cervical spine injury and the high incidence of multilevel contiguous with a lesser percentage of noncontiguous multilevel spinal involvement. SCIWORA (spinal cord injury without radiological abnormality) incidences were in a similar context to the literature available. There was a very low incidence of death. Neurological improvement was seen in 8 operated cases and 4 conservatively treated cases.

Pyogenic or tubercular infection of CSA should be considered as a diagnostic possibility in persons with SCI who are more prone to infections. The management includes aggressive debridement and circumferential fusion along with appropriate medications to control the infection.
