Background: Vertebral osteosarcoma is rare, accounting for 3%–5% of all osteosarcomas. It tends to occur in a slightly older age group. The prognosis is poor compared to osteosarcoma of extremities.
Case Report: We present five cases of vertebral osteosarcomas. The patient’s age ranged from 16 years to 54 years. There were four females and one male. They presented with pain, swelling, or weakness of limbs. Destructive lesions, mixed lytic and sclerotic lesions involving vertebral bodies, and/or pedicles were seen on imaging. A definitive diagnosis could not be made in two cases. On histopathological examination, all the cases turned out to be osteosarcomas.
Conclusion: Osteosarcoma of vertebrae has high rate of recurrence, metastasis, and mortality. Differentiation of vertebral osteosarcoma from other common bony lesions involving the spine is of utmost importance as the treatment is entirely different. Combination therapies including surgery, radiation, and chemotherapy achieve adequate short-term survival rates for vertebral osteosarcoma.

Keywords: Osteosarcoma, Spine, Vertebra.

Introduction: Giant cell tumors (GCTs) are benign, epiphyseal, locally aggressive bone tumors. Pelvic GCTs are sparingly encountered and present a challenging scenario for the surgeon to not only diagnose but also to treat appropriately. Multiple treatment options are available as per the literature but no single approach is universally accepted. Moreover, due to the complex anatomy of the pelvis, novel treatment options have also been tried.
Case Report: A 30-year-old male presented to the outpatient clinic with complaints of gradually progressive dull aching pain in his right hip for 6 months. On radiological investigation, he was found to have a lytic lesion in the right periacetabular region. Image-guided biopsy revealed GCT on histopathological examination. The final management included extended curettage of the tumor and reconstruction of the remaining defect with trabecular metal (TM) augment supplemented with reconstruction plate. The patient resumed full activity and remains asymptomatic and disease free at 5 years follow-up.
Conclusion: To the best of our knowledge, this is the first reported case for the use of TM augment in reconstruction of bone defect following curettage for GCT in pelvis.

Introduction: Pathological fractures of femur are rare and are difficult to manage. Proximal weight bearing portion is more common site for these fractures and are least common in distal third of shaft. Depending on the location and origin of primary tumor or benign lesion, we decide the management. At risk, bone with impending fracture can be managed conservatively. Displaced fractures need surgical intervention. MIREL scoring is used to decide plan of management. Closed technique like intramedullary nailing is preferred over the open technique and gives good results without post-operative morbidity. Radiological investigations are necessary to find out the primary tumor source in metastatic lesions these includes plain radiographs, CT scan, MRI and PET scan. Lab investigations also aid in finding source of primary tumor.
Case Report: This is a case series of 3 patients who had a pathological fracture of the distal third shaft of femur. These patients had metastasis from primary tumor elsewhere in body. All the patients were operated with intramedullary nailing and fixation was done with the aim of reducing pain, avoiding complications such as bed sore, infection, deep venous thrombosis, and regaining the functional outcome as much as possible and improves the quality of life.
Conclusion: All 3 patients with a pathological femur fracture operated with intramedullary nailing were shown to have a significant reduction of pain, regaining of the range of motion of the knee joint and a better quality of life with improvement in performance of activities of daily living.

Introduction: Primary schwannoma of the bone is extremely rare. Spinal schwannoma usually rises in the nerve root or the cauda equina and their branches that occasionally scallop on the adjacent bone. On radiology, their features often mimic those of bone tumors such as osteoblastoma, hemangioma, aneurysmal bone cyst, plasmacytoma, or bone metastasis. Therefore, the diagnosis of pure spinal schwannoma of the bone should be evaluated carefully when referring to radiological and histopathological findings.
Case Report: A 64-year-old female presented with back pain and lower leg dysesthesia. The tumor within the left lamina of the 12th thoracic spine showed an expansile and lytic lesion on computed tomography (CT) and intermediate signals on the T1-weighted image and high signals on the T2-weighted image on magnetic resonance imaging. In addition, an old compression fracture in the same vertebra was observed. ACT-guided biopsy specimen suggested schwannoma. The tumor was successfully excised, and afterward, remission of the symptoms was observed. A definitive diagnosis of intraosseous schwannoma was made. There has been no recurrence in the 6 years following surgery.
Conclusion: We have presented the radiological and histopathological findings as well as the clinical outcomes of an unusual case of intraosseous schwannoma of the posterior element of the 12th thoracic spine. Pre-operative CT-guided biopsy was useful in making a diagnosis and planning a surgical strategy.

Unlocking …the new normal.

The pandemic has entered its third year. Countries around the world witnessed the third wave, characterized by a rapid rise in number of cases and a dramatic fall in those numbers as well.  As the history of any pandemic goes, one would expect further reduction in severity and mortality worldwide.

One striking feature of this Covid 19 pandemic has been the quick development of vaccines and its largescale deployment in most countries of the world. Keeping the initial hesitancy and availability issues aside, there is ample evidence that the vaccines have altered the course of the pandemic which otherwise would have seen worse outcomes.

The world has realized that it is futile to expect a completely covid free world. Many have accepted the reality that humanity will coexist in future with the virus and its various mutations. The strict lockdowns and restrictions imposed in the earlier days have lost their significance particularly in the post vaccine world. As a result, the process of unlocking has already started in a few countries and probably would be the norm very soon in others.

It’s certainly a relief for certain sections of society. The now empty school corridors would again witness kids resuming uninterrupted schooling and other activities along with their peers. Patients with other life threatening diseases, including cancer would continue getting treated and operated without having to worry about interruption in care or best practices. Travel would become easier with fewer restrictions. It would be possible to expect a life reasonably similar to pre-covid world in a few months. The medical fraternity has garnered enough experience and is geared to adapt, evolve and manage challenging situations. It would continue to do so until any unforeseen catastrophic event throws the world out of gear again.

The patient care, peer interactions, research and publication in the various specialities hopefully should be back on track very soon. Unlocking, hopefully, would be the new normal this year.

Pathologic Fractures Secondary to Primary Non-Hodgkin’s Lymphoma of Bone: A Report of Two Cases Treated with Surgery

Case Report | Volume 7 | Issue 3 | JBST September – December 2021 | Page 16-19 | Abigail R Tud, Celestine Marie G Trinidad. DOI:0.13107/jbst.2021.v07i03.61

Background: Primary lymphoma of bone (PLB) is a rare condition accounting for <2% of lymphomas among adults. Diagnosis is confirmed through clinical features, radiologic findings, and immunohistochemical studies. Treatment consists primarily of chemotherapy and radiotherapy. A lack of consensus remains, however, regarding the role of surgery on prognosis. Interventions with potential to improve quality of life therefore warrant further investigation. The authors report two cases of PLB treated with surgery, with favorable outcomes.
Case Presentation 1: A 21-year-old female presented with the left knee pain unaccompanied by constitutional symptoms. Imaging studies showed an isolated pathologic fracture of the left proximal tibia. Histopathology showed an atypical proliferation of large round cells, which stained diffusely and strongly positive for CD20. 90% of the cells also stained positive for the proliferation marker Ki-67. These findings were consistent with a high-grade B-Cell non-Hodgkin’s lymphoma (NHL). The tibial lesion was managed with direct fracture reduction and knee arthrodesis. Six cycles of chemotherapy were completed. Current Musculoskeletal Tumor Society (MSTS) score is 28/30, without evidence of recurrence 3 years post-surgery.
Case Presentation 2: A 69-year-old male sustained a pathologic subtrochanteric fracture after falling on his left hip. Diagnostic imaging revealed no other osseous lesions. Biopsy specimens showed a proliferation of atypical lymphoid cells, and on immunohistochemistry, these were diffusely and strongly positive for lymphocyte common antigen (CD45) and CD20. This was consistent with a high-grade B-Cell NHL. After proximal femoral nailing was performed, no further treatment was given. The patient is currently 2 years post-surgery with MSTS score of 28/30, and no signs of recurrence or metastases.

Conclusion: Current approach to treatment of PLB is multi-modal, but guidelines for surgical intervention are unavailable. Few reports have been made on outcomes after surgery. Pathologic fracture fixation is an option among select patients, affording satisfactory functional outcomes while minimizing morbidity.
