Although bone tissue contains no pain receptors, a bone fracture is painful for several reasons: [4] Breaking in the continuity of the periosteum, with or without similar discontinuity in endosteum, as both contain multiple pain receptors. Edema and hematoma of nearby soft tissues caused by ruptured bone marrow evokes pressure pain.
It is thus a form of child bone fracture. It is a common injury found in children, occurring in 15% of childhood long bone fractures. [3] This type of fracture and its classification system is named for Robert B. Salter and William H. Harris who created and published this classification system in the Journal of Bone and Joint Surgery in 1963. [4]
Symptoms may include pain, swelling, deformity, and bruising. [2] Complications may include damage to the median nerve. [1] It typically occurs as a result of a fall on an outstretched hand. [2] Risk factors include osteoporosis. [2] The diagnosis may be confirmed via X-rays. [2] The tip of the ulna may also be broken. [4]
A pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads. [1] This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infection (such as osteomyelitis), inherited bone disorders, or a bone cyst.
Juvenile osteoporosis is osteoporosis in children and adolescents. Osteoporosis is rare in children and adolescents. When it occurs, it is usually secondary to some other condition, [1] e.g. osteogenesis imperfecta, rickets, eating disorders or arthritis. In some cases, there is no known cause and it is called idiopathic juvenile osteoporosis ...
Dual-energy X-ray absorptiometry (DEXA scan) is considered the gold standard for the diagnosis of osteoporosis. Osteoporosis is diagnosed when the bone mineral density is less than or equal to 2.5 standard deviations below that of a young (30–40-year-old [4]:58), healthy adult women reference population.
Examples of periosteal reactive bone in selected specimens of Triceratops. A periosteal reaction can result from a large number of causes, including injury and chronic irritation due to a medical condition such as hypertrophic osteopathy, bone healing in response to fracture, chronic stress injuries, subperiosteal hematomas, osteomyelitis, and cancer of the bone.
Pressure ulcers can trigger other ailments, cause considerable suffering, and can be expensive to treat. Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
