It is characterized by characteristic facial anomalies, cervical kyphosis, cardiorespiratory disorders, and multiple joint dislocations. We present a case of a 15-year-old male with unstable neuropathic knee joint instability in a known case of LS. The paucity of literature on the management of this rare condition puts an orthopedician in dilemma regarding the optimal treatment. Case Report: A 15-year-old male, known case of LS, presented to our outpatient department with pain and instability in the right knee for 2 years. Clinically, the patient was having syndromic facies. The diagnosis of LS was confirmed on gene mapping. The right knee was swollen with medial joint line tenderness and restricted flexion. The patient had coronal plane valgus instability. The hypertrophied synovium eroded the articular surface. The radiograph of knee was suggestive of neuropathic arthropathy in f...

The study also analyses the pain relief, recurrence, radiological outcome and complications after percutaneous sclerotherapy. Materials and methods: A total of 43 patients with ABC were managed by fluoroscopy assisted percutaneous intralesional sclerotherapy with 3% Injection Polidocanol under suitable anaesthesia. The pain relief was assessed by Visual Analog Scale (VAS) and the progressive healing of the lesion by Rastogi Classification. Patients were evaluated clinico-radiologically, pre-operatively and at monthly interval for the first three months and then at 6 months, one year and two years follow up. Result: The VAS score decreased significantly at six months follow up and was zero (No pain) at one year follow up. Out of 43 patients, 37 patients had Degree I (excellent) residual lesion and 6 patients had degree II (good) lesion at one year follow-up as per Rastogi classification. The lesions resolved completely by two-year follow-up with all 43 patients having Degree (excellent) I resolution. Conclusion: Our study highlights the efficacy of percutaneous intralesional polidocanol in the treatment of ABC's. The procedure is safe, simple and effective with excellent outcome. Sclerotherapy is highly beneficial for deep lesions which are difficult to assess and for comorbid patients who are medically unfit for surgery. Our study strongly advocates the use of sclerotherapy as the first line treatment for ABC, considering its clinical and radiological efficacy.

Methods: This was a retrospective analysis of 16 cases of cervicothoracic junction (CTJ) spinal TB; 11 patients were managed operatively, while five were managed conservatively. Patients’ outcomes were assessed at 1 month, 1 year, and yearly thereafter and included an analysis of multiple outcome scores, various radiographic parameters, and sensitivity or resistance to anti-tubercular therapy. Results: Patients averaged 25.94 years of age, and typically had three-level vertebral involvement. They were followed for a mean duration of 24 months, and the duration of anti-tubercular therapy averaged 17 months. Patients demonstrated clinical improvement on Japanese Orthopedic Association score and Neck disability index (P < 0.005) starting from 1 month following initiation of treatment which continued ...

Here, we present a projectile injury to the paediatric lumbar spine without any osseous disruption in a 5-year-old child requiring surgical management. CASE PRESENTATION: A 5-year-old child presented with a gunshot injury to the pediatric lumbar spine. On radiological imaging, there was no osseous disruption and an intraspinal canal projectile was embedded in an organised infected complex, compressing onto the left-sided L5 traversing nerve root with resultant grade 4 motor power of the left Extensor Hallucis Longus (EHL). Under fluoroscopic guidance using two separate mini-open incisions, the pellets were extracted. One from the spinal canal through leftsided L4 laminotomy and the other from the right paraspinal region. Post-surgical decompression and pellet retrieval there was gradual recovery to grade 5 motor power of Left EHL and improvement in the general condition of the child. CONCLUSION: The absence of osseous disruption can be attributed to the size of the projectile, widely spaced interlaminar spaces in the lumbar spine due to the absence of lumbar lordosis in the pediatric group and flexibility of the pediatric spine owing to its ligamentous laxity.

We evaluated the Maximal Spinal Cord Compression (MSCC) ratio on Magnetic Resonance Imaging (MRI), the time interval between the appearance of neurological deficit and the initiation of management, spasticity as per Modified Ashworth Scale, presence of drug resistance, and the Lower Extremity Motor Score (LEMS). All patients were given anti-tubercular chemotherapy. We surgically managed 8 patients of which 6 required decompression alone, while 2 patients required additional instrumentation. 2 patients were managed conservatively of which 1 responded favorably to conservative treatment while the other patient showed a worsening of neurology following the detection of drug resistance and abrupt discontinuation of chemotherapy. The mean LEMS on admission was 20.2, which improved to 38.5 at the end of 1 year (p-value <0.05). The patients in whom the time interval between the onset of neurological deficit and the initiation of management was fewer than 6 weeks showed better LEMS and milder or absent spasticity at follow-up (p-value <0.05). The MSCC ratio did not have a significant correlation with the LEMS (p-value >0.05).

The cast composites were developed by stir cast method and its tribological behavior were experimentally evaluated using a pin-on-disc tribometer adopting loads and sliding velocities ranging from 20-100N and 0.314-1.5740m/s respectively. The predictions of coefficient of friction and wear rates of matrix alloy and the developed cast composites by ANN approach do agree very closely with the experimental data.

Retrospective analysis of 33 patients with thoracolumbar SCI who underwent delayed surgery (≥ 72hrs post-trauma) with a minimum follow-up of 1 year (average:32.55 months) was done. The parameters studied included age, sex, co-morbidities, mode of trauma, associated trauma, level and number of vertebrae involved, fracture morphology, thoracolumbar injury classification and severity score (TLICS), maximal spinal cord compression (MSCC), signal changes in the cord, neurological deficit as per the American Spinal Injury Association (ASIA) scale, lower extremity motor score (LEMS), bowel bladder involvement, time interval between trauma and surgery. Mean time interval from injury to spine surgery was 24.45 days. At the end of 1-year follow-up, 17(51.5%), 12(36.36%), and 3(9.1%) patients had ≥ 1, ≥ 2, and ≥ 3-grade ASIA improvement, respectively. The mean LEMS rose to 33.86 from 17.09 (P < 0.001). 8 out of 20 patients with bladder involvement showed improvement. 4 patients succumbed, 22 were ambulatory, and 7 remained non-ambulatory. On comparing various parameters, pre-operative LEMS score (P-value: < 0.001), cord signal changes (P-value:0.002), and presence of cord transection (P-value:0.007) differed significantly in the above-mentioned three groups, while age (P-value:0.442), average TLICS (P-value:0.872), time from injury to surgery (P-value:0.386) did not differ significantly. This study highlights that there is still a significant scope for neurological improvement even after delayed surgery in patients with thoracolumbar SCI. The lower the LEMS score at the time of presentation, signal changes in the cord and presence of cord transection have a significant influence on unfavourable clinical outcomes at the end of 1-year post-surgery.

Case Description: We report a rare case of a dysplastic C1 vertebra (assimilation to the right occiput and C2, a nonseparated left odontoid, and discontinuity in both anterior and posterior arches of the atlas) in a 6-year-old child with progressive torticollis. Notably, the mechanism of torticollis was not a rotatory subluxation of C1-C2, but differential growth between C1-C2. The child underwent a successful C1-C2 Goel and Harms fusion with reduction/correction of the torticollis. Conclusion: Torticollis caused by differential growth between the C1 and C2 vertebrae resulting in a nonrotatory subluxation/torticollis in a 6-year-old child, was successfully managed with a C1-C2 Goel and Harm’s fusion.

Objective: To study the neurological recovery in patients with progressive neurological deficit undergoing delayed decompression and fixation in tuberculosis of spine. Methods: Retrospective analysis of 50 cases with thoracolumbar tuberculosis of spine, undergoing posterior decompression and instrumentation was done. Parameters like time interval between appearance of neurological deficit to decompression surgery, maximal spinal cord compression, neurology on admission, presence of drug resistance, and number of vertebrae involved were evaluated. The subjects were divided into 2 groups depending on neurological improvement measured with LEMS (Lower Extremity Motor Score) at the end of 1-year follow-up. Results: The mean LEMS score on admission was 27.72 (SD 12.88), which improved to 40.80 (SD 10.46) at the end of 1 year ( P < .001). A total of 26 (52%) subjects were categorized into “Satisfactory” outcome (LEMS >10) group and re...

"Homicide" which is violence inflicted by one human on another is violence at it's extreme and is an indicator of the social and psychological wellbeing as well as security provided by the social system to the members of the society. Objectives: To look at the profile of homicide victims in Aurangabad, Maharashtra form 2004 to 2008 A.D. Materials and Methods: All the cases of homicide recorded in the autopsy centre of government hospital Aurangabad from Jan 2004 to Dec 2008 were taken for the study and retrospectively analyzed using SPSS 15. Results: There were a total of 163 cases of homicide recorded with 130(79.8%) of them being males. The average homicide rate for the period of five years from 2004 to 2008 AD in Aurangabad was 32.6 per year. In terms of the population base there were 44.34 homicides per 1 million The age category most common was 15-45(69.4%). Among the victims farmers and labourers were the commonest occupations. Religion of the victim or whether they belonged to the urban or rural background did not have any impact on the susceptibility to be victims of homicide in this study. Head injury(57.1%) was found in maximal number of victims as the cause of death and the wound was inflicted by a hard/blunt weapon in majority of victims (65.6%). Burns as a cause of death was seen only in women with dowry as the primary cause. Conclusion: The commonest victim profile was of a married, male farmer or laborer of no specific religion, either from urban or rural background who had died in a majority of cases due to an injury inflicted only on his head by a hard/blunt weapon. Among women the method of homicide using fire was more likely. The decreasing child gender ratio over the last decade also seems to be a bad indicator for future trends of homicide in Aurangabad.
