Vol 12 ppt
This document discusses numerous cases of patients presenting with bone lesions that were initially suspected to be metastatic disease but were later determined to be other diagnoses. Case 1169 describes a 47-year-old female whose stress fracture of the femoral neck was mistaken for a metastatic lesion. Imaging and biopsy revealed the lesion was actually a pseudotumor caused by osteoporosis. Similarly, Case 1169.1 involves a 43-year-old female on steroids whose bilateral hip pain was from stress fractures, not metastases as indicated on her bone scan. The document emphasizes that various benign bone conditions can resemble metastatic bone cancer on imaging and biopsy is often needed for accurate diagnosis.
Vol 1 ppt
This document provides a summary of 50 cases of osteoid osteoma and osteoblastoma. Case 1-50 cover osteoid osteoma, with the classic presentation of a painful nidus most commonly in long bones that is diagnosed using imaging such as CT scan and bone scan. Case 51-94 cover osteoblastoma, a larger variant of osteoid osteoma that is treated surgically via curettage. The remainder of cases provide further examples and variations of these two conditions.

This document discusses several cases of classic osteosarcoma. It begins with case 108, describing a 16-year-old male with classic osteosarcoma in the femur. It then moves to case 451, describing a 17-year-old male. Several other cases are then summarized, describing patients of varying ages with classic osteosarcoma located in different bones including the femur, tibia, fibula, and humerus. For each case, relevant imaging, specimens, and treatments are briefly discussed.
An Atlas of Musculoskeletal Oncology: Volume 4
Periosteal chondroma is a benign cartilage-forming tumor that occurs on the surface of tubular bones. It has a similar pathology to enchondroma but is located on the bone surface rather than internally. Radiographically, it shows slight erosion of the adjacent cortex with calcification at the periphery and base. Treatment is simple resection without disturbing the underlying cortex. Growth beyond 3-4 cm in diameter raises concern for possible progression to peripheral surface chondrosarcoma.
Vol 2 ppt
This document describes several cases of classic osteosarcoma. It begins with an overview of classic osteosarcoma, including that it most commonly affects children and young adults, occurs in long bones like the femur and tibia, and patients typically present with pain followed by a tumor mass. It then describes the staging process and treatments, including chemotherapy and surgical resection. Multiple patient cases are then described in detail, with imaging findings, surgical procedures, outcomes, and in some cases, recurrence of disease.
Vol 3 ppt
The document describes several variants of osteosarcoma, including hemorrhagic, parosteal, and periosteal osteosarcoma. Hemorrhagic osteosarcoma is a very lytic and hemorrhagic variant that can resemble an aneurysmal bone cyst. Parosteal osteosarcoma arises on the surface of bone and has a good prognosis. Periosteal osteosarcoma contains cartilage and arises from long bones, typically in the second decade of life. Each variant is illustrated through case examples showing imaging, specimens, and histology.
Vol 10 ppt
This document discusses giant cell tumor of bone (GCT), a benign bone tumor typically seen in young adults. It most commonly occurs in the ends of long bones near joints like the knee. The tumor is lytic and geographic on x-ray. Treatment typically involves aggressive curettage followed by packing the defect with bone graft or cement, with a 5-10% recurrence rate. Even though considered benign, 1-2% of GCTs can metastasize to the lungs. Radiation can increase risk of malignant transformation. Several case examples are presented demonstrating features, treatment approaches, and outcomes of GCT in various bone locations.
Vol 11
The document discusses metastatic carcinoma to bone. Some key points:
- Metastatic carcinoma commonly spreads to bone, with breast and prostate cancers being most common. The spine is the most frequent site.
- Lesions from different cancers have varying appearances. Breast cancers tend to be lytic while prostate cancers are often blastic.
- Treatment involves radiation, chemotherapy, surgery like fixation or prostheses, and bisphosphonates to reduce osteoclastic activity.
- Prognosis depends on cancer type, with prostate having best survival and lung having worst. Pathological fractures worsen survival.

Fractures & complications
The document summarizes the fracture healing process and potential complications.

It outlines the evaluation, surgical approaches, techniques for open reduction and internal fixation using plates or pins, post-operative care, and potential complications. The prognosis depends on factors like the timing of surgery and whether the radius fracture and joint dislocation are properly reduced.
Fracture compli & mx
This document discusses various complications that can arise from fractures, categorized as immediate, early, or late complications. Immediate complications include hypovolaemic shock and injuries to vessels, muscles, tendons, joints or viscera. Early complications involve shock, fat embolism, DVT/PE, infection, and compartment syndrome. Late complications relate to bone union like delayed-union, non-union, mal-union or cross-union. Other late issues involve avascular necrosis, joint stiffness, reflex sympathetic dystrophy, myositis ossificans or osteoarthritis. The management of many conditions involves immobilization, early stabilization of fractures, prevention of complications, and surgical intervention if needed.

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
