Pathology - Lower Limb Flashcards
Stress Fracture
Result of repeated stresses to a bone that would not be injured by isolated forces of the same magnitute
Linear/Longitudinal fracture
Extends along the length of the bone
Jones’ fracture
A transverse fracture at the base of the fifth metatarsal; an avulsion injury that results from plantar flexion and inverison of the foot; one of the most frequent injuries of the foot
Pott’s Fracture
Involves both malleoli (of tibia and fibula) with dislocation of the ankle joint
Osgood-Schlatter Disease
The tibial tuberosity is separated from the shaft of the tibia - visualized on the lateral projection of the knee
Ewings Sarcoma
Primary malignant tumor arising in the bone morrow in children and young adults - seen as a large portion of bone destruction in the central portion of the shaft of a long bone
Osteogenic Sarcoma
Generally occurs in long bones (especially the knee) - pulmonary metasteses develop early - appears as a sunburst pattern with bony spicules extending outward in a radiating fashion
Osteochondroma
Benign projection of bone with a cartilaginous cap (especially the knee) - the long axis of the tumor is parallel to the parent bone
Osteomalacia
Insufficient mineralization of the adult skeleton - appears radiographically as a lose of bone density - bones may bend or give way upon weight bearing. Less technique needed
Rickets
Infant/childhood equivalent of osteomalacia
Osteomyelitis
Inflammation of the bone and bone marrow causes by infectious organisms that reach the bone
Rhematoid Arthritis
Chronic systemic disease - non-infectious inflammatory arthritis of the hand and foot joint. Less technique needed
Osteoarthritis
Degenerative Joint Disease - loss of joint cartilage and reactive new bone formation - predominately affects weight bearing joints and interphalangeal joints of the fingers - part of the wear and tear of the aging process. Less technique needed
Tri-Malleolar Fracture
Fracture of the medial and lateral malleoli and posterior tip of the distal tibia
