Abstract:
Synovial metaplasia was described in animal studies since the 1950s and was assumed to be a reaction to tissue disruption and theoretically related to the embryological formation of diarthrodial joints in utero. Since the description of the phenomenon in the cutaneous layer in a small case series in 1987, the prevalence has increased gradually with case reports and series published on many variations of its presentations and inciting events. We present a case of a hypertensive, otherwise physically fit 38-year-old female with a one-year history of coxalgia unresponsive to oral analgesia and discuss the possibility that the cutaneous metaplastic synovial cyst is an adaptive response to multiplanar shear forces and forms part of a spectrum of potential clinical presentations based on location.

Shearing Stress
The average shearing stress can be calculated by dividing the shear by the area of the cross-section.

Shear Diagram
First, a free-body diagram of the beam is drawn, representing all the external forces and internal reactions acting on the beam. One can calculate the reaction forces at each support by employing the equilibrium equations of force and moment. The vertical component...
