Calcaneal fractures are often attributed to shearing stress adjoined with compressive forces combined with a rotary direction (Soeur, 1975 [7]). These forces are typically linked to injuries in which an individual falls from a height, involvement in an automobile accident, or muscular stress where the resulting forces can lead to the trauma of ...
Calf squeeze test in a person with a right Achilles tendon rupture. Diagnosis is based on symptoms and history of the event. People describe it like being kicked or shot behind the ankle. During physical examination, a gap may be felt above the heel unless swelling is present.
The Thompson test (also called Simmonds' test or Simmonds-Thompson test) is used in lower limb examination to test for the rupture of the Achilles tendon. [ 1 ] [ 2 ] The patient lies face down with feet hanging off the edge of the bed.
In orthopedic medicine, the Sanders classification is a system of categorizing intra-articular calcaneal fractures based on the number of articular fragments seen on the coronal CT image at the widest point of the posterior facet.
The differential diagnosis for heel pain is extensive and includes pathological entities including, but not limited to, the following: calcaneal stress fracture, septic arthritis, calcaneal bursitis, osteoarthritis, spinal stenosis involving the nerve roots of lumbar spinal nerve 5 (L5) or sacral spinal nerve 1 (S1), calcaneal fat pad syndrome ...
Stress fractures can be described as small cracks in the bone, or hairline fractures. Stress fractures of the foot are sometimes called "march fractures" because of the injury's prevalence among heavily marching soldiers. [2] Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula ...
where is the yield stress, is the crack length, is the Young's modulus, and is the remote applied stress. Under fatigue loading, the range of movement of the crack tip during a loading cycle Δ δ t {\displaystyle \Delta \delta _{\text{t}}} can be used for determining the rate of fatigue growth using a crack growth equation .
