BackgroundPlasma interleukin-33 (IL-33), a cytokine associated with inflammatory and autoimmune disease, has been described to be significantly raised in osteonecrosis of the femoral head (ONFH) and hence was recommended for use as a marker for ONFH. The concentration of plasma interleukin-33 level has not been estimated in any studies conducted in patients with sickle cell disease (SCD); hence, we investigated the levels of plasma interleukin-33 in patients with sickle cell disease with or without ONFH to assess whether it can be used as a marker for the early detection of ONFH in this disease also. MethodsForty-four consecutive patients with sickle cell disease with osteonecrosis of the femoral head and matched controls without ONFH were evaluated for plasma interleukin-33 levels by enzyme-linked immunosorbent assay (ELISA). All patients were confirmed for sickle cell disease using high-performance liquid chromatography (HPLC). ONFH was diagnosed in patients with sickle cell disease using clinical-radiological findings. Univariate and multivariate analyses were performed using the IL-33 level as the dependent variable. ResultsPlasma IL-33 levels were comparable in 44 patients with sickle cell disease with osteonecrosis of the femoral head as compared with 24 patients with sickle cell disease without ONFH (2.05 ± 4.57 pg/mL versus 1.50 ± 2.89 pg/mL, p-value = 0.590). There was no significant difference in IL-33 levels in different stages of avascular necrosis (AVN). ConclusionsPlasma interleukin-33 levels cannot act as a marker of ONFH as were being considered in idiopathic ONFH or ONFH caused by other causes such as trauma and chronic steroid or alcohol usage.

This study aims to evaluate whether surgical site vancomycin mixed in bone grafts and local vancomycin mixed in normal saline wash before wound closure decrease the infection rates in patients undergoing lumbar spinal instrumentation and posterolateral fusion. A retrospective study was performed on cases between 2017 and 2019, who underwent lumbar spine instrumentation and posterolateral fusion for lumbar canal stenosis or listhesis. The routine prophylactic procedures were performed in all patients as per institutional protocol. Patients' records were analysed and categorised into two groups, the vancomycin group (VG), where vancomycin mixed in bone graft and normal saline wash was used at the surgical site, and the control group (CG), where vancomycin was not used. The study included 63 patients, 31 in VG and 32 in CG. There is no statistical difference in age, sex, and diabetes mellitus in both groups. A total of seven cases were infected, six in CG (6/32) and one in VG (1/31). Out of six infections in CG, three patients had diabetes and four infected cases underwent surgery for debridement. In VG, the only single case got infected and treated with intravenous antibiotics. We found that the use of vancomycin added to the bone graft and normal saline in posterior lumbar spinal instrumentation and posterolateral fusion is associated with significantly lower rates of infection (p value=0.049).

Objective:To evaluate the usefulness of conventional spinal surgery as palliative procedure to rehabilitate dorsolumbar injuries in a rural setup.Materials and Methods:Twenty-three patients with dorsolumbar spine injury with complete paraplegia were assessed on the clinical and social rehabilitation parameters after surgical stabilization at Acharya Vinoba Bhave Rural Hospital Sawangi, Wardha, India. The study group comprised 21 male and 2 female patients. The dorsolumbar spine injury was fixed by conventional posterior instrumentation using short-segment pedicle screw system and Harrington rod system with or without fusion. Functional and neurologic outcome was recorded in the follow-up period by using Functional Independence Measure and Frankel grade, respectively. Correlation and analysis of results was established statistically.Results:Functional outcome showed statistically significant improvement. Social cognition was found intact in a significant number of patients.Conclusion:This study demonstrates the usefulness of conventional instrumentation as palliative surgical approach to stabilize and rehabilitate patients from deprived sector of rural India.

Study DesignProspective study conducted at Jawaharlal Nehru Medical College, Datta Meghe Institute of Medical Sciences, Wardha, India.PurposeTo show the efficacy of decompression in the late presentation of cervical spinal cord disorders.Overview of LiteratureStudies by various authors have shown that early spinal decompression results in better neurological outcomes.MethodsFrom January 2003 to January 2005, 11 of the 41 patients with cervical spinal cord compression, meeting the inclusion criteria, underwent anterior decompression; interbody graft placement and stabilization by anterior cervical locking plate. The neurologic and functional outcomes were recorded.ResultsFive patients had spinal cord injury and 6 patients had compressive cervical myelopathy. Complications included 1 death and 1 plate loosening. No patient lost their preoperative neurological status. One patient had no improvement, 2 patients showed full recovery. The mean follow-up is 28.3 month. At the of rehabilitation, 6 were able to walk without support), 2 could walk with support, and 1 needed a wheelchair. The average American Spinal Injury Association motor score on admission to the hospital, 32.8 (standard deviation [SD], 30.5); admission to rehabilitation, 38.6 (SD, 32.4); discharge from rehabilitation, 46.2 (SD, 33.7). The most recent follow-up was 64.0 (SD, 35.3).ConclusionsThe anterior approach for cervical decompression allows for adequate decompression. This decompression is the best chance offered in even late reported cases, including posttraumatic cases where there is no evidence of cord transactions. The use of anterior cervical plates reduces the chances of graft loosening, extruding, or collapsing.
