A Rare Case of Extraosseous Osteosarcoma (EOS) of Parotid Gland.

Extraosseous osteosarcoma is a rare malignant soft tissue neoplasm, and extraosseous osteosarcoma of the parotid gland is very rare. It has a very aggressive course, and there are no standardized treatment guidelines. We report the case of a 20 year old male patient who presented with history of right neck swelling since 6 years for which he had undergone right parotid surgery 5 years ago. The final histopathological report indicated that the mass was a pleomorphic adenoma. One year after the first surgery, the patient experienced recurrence of swelling over the operated site, and the size of the swelling has been increasing gradually since then. He was evaluated clinically, and a large mass was noted over the upper aspect of the right upper neck, extending to the occipital and parotid regions. An MRI scan was done which showed a 12 × 10 × 8 cm lesion centred in the right parotid gland, involving paraspinal muscles, C1-C2 vertebrae and extending into the parapharyngeal space. FNAC of the lesion showed features of pleomorphic adenoma. The patient underwent a complete excision of the tumour. The patient's post-operative period was uneventful. The final histopathological report of the patient was extraosseous osteosarcoma of the parotid gland. The patient was referred for adjuvant radiotherapy. He has been on regular follow-up for the past 6 months and has shown no sign of recurrence. EOS is an extremely rare tumour of the head and neck region which often requires extensive surgical resection with or without adjuvant radiotherapy. It has a high rate of local recurrence and a very low disease free survival. Such patients should be kept on a close follow-up.

Spinal Injury in Indian Children: Review of 204 Cases.

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.

Functional and Radiological Outcomes of Anterior Decompression and Posterior Stabilization via Posterior Transpedicular Approach in Thoracic and Thoracolumbar Pott's Disease: A Retrospective Study.

STUDY DESIGN: This is a retrospective study. PURPOSE: To determine the efficacy and safety of a posterior transpedicular approach with regard to functional and radiological outcomes in people with thoracic and thoracolumbar spinal tuberculosis. OVERVIEW OF LITERATURE: Spinal tuberculosis can cause serious morbidity, including permanent neurological deficits and severe deformities. Medical treatment or a combination of medical and surgical strategies can control the disease in most patients, thereby decreasing morbidity incidence. A debate always existed regarding whether to achieve both decompression and stabilization via a combined anterior and posterior approach or a single posterior approach exists. METHODS: The study was conducted at the Indian Spinal injuries Centre and included all patients with thoracic and thoracolumbar Pott's disease who were operated via a Posterior transpedicular approach. Data regarding 60 patients were analyzed with respect to the average operation time, preoperative and postoperative, 6 months and final follow-up American Spinal Injury Association (ASIA) grading, bony fusion, implant loosening, implant failure, preoperative, postoperative, 6 months and final follow-up kyphotic angles, a loss of kyphotic correction, Oswestry disability index (ODI) score, and visual analog scale (VAS) score. Data were analyzed using either a paired t -test or a Wilcoxon Signed Rank test. RESULTS: The mean operation time was 260±30 minutes. Fifty-five patients presented with evidence of successful bony fusion within a mean period of 6±1.5 months. Preoperative dorsal and lumbar angles were significantly larger than postoperative angles, which were smaller than final follow-up angles. The mean kyphotic correction achieved was 12.11±14.8, with a mean decrease of 5.97 and 19.1 in VAS and ODI scores, respectively. CONCLUSIONS: Anterior decompression and posterior stabilization via a posterior transpedicular approach are safe and effective procedures, with less intraoperative surgical duration and significant improvements in clinical and functional status.

Fracture Management In Osteopetrosis : An Intriguing Enigma A Guide For Surgeons.

Osteopetrosis is a disorder of diminished bone resorption with hard and brittle bones resulting in high rates of perioperative complications during an operative intervention. We present a series of 4 Subtrochanteric fractures treated surgically in 3 patients of Osteopetrosis in a tertiary level Orthopaedic centre over the last 3 years with an aim to highlight our preparation and technique, especially as a guide to other surgeons, to minimize the complication rates and optimise the results. The patients had a mean Harris Hip Score of 85, at a mean follow up of 21.5 months ; the fractures united and all patients successfully returned to their normal activities of daily living.
