Seinsheimer Classification
The Seinsheimer classification is a system of categorizing subtrochanteric hip fractures based on the fracture pattern of the proximal femoral shaft. The classification was developed by Frank Seinsheimer III in 1978. In the published work, fifty-six patients were treated for subtrochanteric fractures, and their fractures were "classified according to the number of major fragments and the locations and shapes of the fracture lines." This system of classification was used to assess the correlation between type of fracture and success of treatment. A later study of 50 subtrochanteric fractures, which were assessed using the Seinsheimer classification, criticized the classification system for having poor inter-rater reliability. They noted that "Earlier studies of pertrochanteric icand femoral neck fractures show that the use of classification systems is often difficult, with low agreement (Frandsen et al. 1988, Andersen et al. 1990, Gehrchen et al. 1993). The results of these stud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hip Fracture
A hip fracture is a break that occurs in the upper part of the femur (thigh bone). Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. Usually the person cannot walk. They most often occur as a result of a fall. (Femoral head fractures are a rare kind of hip fracture that may also be the result of a fall but are more commonly caused by more violent incidents such as traffic accidents.) Risk factors include osteoporosis, taking many medications, alcohol use, and metastatic cancer. Diagnosis is generally by X-rays. Magnetic resonance imaging, a CT scan, or a bone scan may occasionally be required to make the diagnosis. Pain management may involve opioids or a nerve block. If the person's health allows, surgery is generally recommended within two days. Options for surgery may include a total hip replacement or stabilizing the fracture with screws. Treatment to prevent blood clots following surgery is recommended. About 15% of wom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bone Fracture
A bone fracture (abbreviated FRX or Fx, Fx, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a ''comminuted fracture''. A bone fracture may be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture. Signs and symptoms Although bone tissue contains no pain receptors, a bone fracture is painful for several reasons: * 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. * Involuntary muscle spasms trying to hold bone fragments in place.

Femur
The femur (; ), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint. By most measures the two (left and right) femurs are the strongest bones of the body, and in humans, the largest and thickest. Structure The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have thicker pelvic bones, causing their femora to converge more than in males. In the condition ''genu valgum'' (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme is ''genu varum'' (bow-leggedness). In the general populatio ...

Inter-rater Reliability
In statistics, inter-rater reliability (also called by various similar names, such as inter-rater agreement, inter-rater concordance, inter-observer reliability, inter-coder reliability, and so on) is the degree of agreement among independent observers who rate, code, or assess the same phenomenon. Assessment tools that rely on ratings must exhibit good inter-rater reliability, otherwise they are not valid tests. There are a number of statistics that can be used to determine inter-rater reliability. Different statistics are appropriate for different types of measurement. Some options are joint-probability of agreement, such as Cohen's kappa, Scott's pi and Fleiss' kappa; or inter-rater correlation, concordance correlation coefficient, intra-class correlation, and Krippendorff's alpha. Concept There are several operational definitions of "inter-rater reliability," reflecting different viewpoints about what is a reliable agreement between raters. There are three operational defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lesser Trochanter
The lesser trochanter is a conical posteromedial bony projection of the femoral shaft. it serves as the principal insertion site of the iliopsoas muscle. Structure The lesser trochanter is a conical posteromedial projection of the shaft of the femur, projecting from the posteroinferior aspect of its junction with the femoral neck. The summit and anterior surface of the lesser trochanter are rough, whereas its posterior surface is smooth. From its apex three well-marked borders extend: * two of these are above ** a medial continuous with the lower border of the femur neck ** a lateral with the intertrochanteric crest * the inferior border is continuous with the middle division of the linea aspera Attachments The summit of the lesser trochanter gives insertion to the tendon of the psoas major muscle and the iliacus muscle; the lesser trochanter represents the principal attachment of the iliopsoas. Anatomical relations The intertrochanteric crest (which demarcates the junctio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greater Trochanter
The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system. It is directed lateral and medially and slightly posterior. In the adult it is about 2–4 cm lower than the femoral head.Standring, Susan, editor. ''Gray’s Anatomy: The Anatomical Basis of Clinical Practice''. Forty-First edition, Elsevier Limited, 2016, p. 1327. Because the pelvic outlet in the female is larger than in the male, there is a greater distance between the greater trochanters in the female. It has two surfaces and four borders. It is a traction epiphysis. Surfaces The ''lateral surface'', quadrilateral in form, is broad, rough, convex, and marked by a diagonal impression, which extends from the postero-superior to the antero-inferior angle, and serves for the insertion of the tendon of the gluteus medius. Above the impression is a triangular surface, sometimes rough for part of the tendon of the same muscle, sometimes smooth for the interposi ...

Femoral Fracture
A femoral fracture is a bone fracture that involves the femur. They are typically sustained in high-impact trauma, such as Traffic collision, car crashes, due to the large amount of force needed to break the bone. Fractures of the diaphysis, or middle of the femur, are managed differently from those at the head, neck, and trochanter. Signs and symptoms Fractures are commonly obvious, since femoral fractures are often caused by high energy trauma. Signs of fracture include swelling, deformity, and shortening of the leg. Extensive soft-tissue injury, bleeding, and shock are common. The most common symptom is severe pain, which prevents movement of the leg. Diagnosis Physical exam Femoral shaft fractures occur during extensive trauma, and they can act as distracting injuries, whereby the observer accidentally overlooks other injuries, preventing a thorough exam of the complete body. For example, the ligaments and meniscus of the ipsilateral (same side) knee are also commonly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
