Shingles results when the dormant varicella virus is reactivated. Once the chickenpox has resolved, the virus can remain inactive (dormant) in human nerve cells ( dorsal root ganglia or cranial nerves ) for years or decades, after which it may reactivate. Chickenpox, also called varicella, results from the initial infection with the virus, typically occurring during childhood or adolescence. Both originate from infection of an individual with the varicella zoster virus (VZV). Shingles and chickenpox are distinct human diseases but are closely related in their life cycles. If the rash involves the eye, vision loss may occur. In those with poor immune function the rash may occur widely. The rash usually heals within two to four weeks however, some people develop ongoing nerve pain which can last for months or years, a condition called postherpetic neuralgia (PHN). Otherwise, there are typically few symptoms though some people may have fever or headache, or feel tired. Two to four days before the rash occurs there may be tingling or local pain in the area. Typically the rash occurs in a single, wide mark either on the left or right side of the body or face.

Shingles, also known as zoster or herpes zoster, is a viral disease characterized by a painful skin rash with blisters in a localized area.

In other words, the joint capsule could change its morphology dynamically depending on the hip position. The zona orbicularis was interpreted as the inward protrusion caused by dynamic change of the joint capsule, rather than the local collar. This inward protrusion was not histologically independent of the joint capsule. The Thiel's method specimens showed that the inner surface of the joint capsule protruded inward toward the femoral neck during hip extension. Micro-computed tomography images revealed that the inward protrusion of the joint capsule narrowed the articular cavity, and the ratio of its narrowest area to that of the femoral neck was less at hip extension than at hip flexion. The remaining three formalin-embalmed bodies were examined histologically. During formalin fixation of six hips from these three bodies, one side was maintained at hip extension and the other at flexion. The joint capsules in three formalin-embalmed bodies were sturied by micro-computed tomography. Six and three of the donated bodies, respectively, were embalmed using 8% formalin and Thiel's method. Twelve hips from nine bodies donated to science were examined. The aim of this study is to investigate the characteristics of the inner side of the joint capsule comprehensively. Despite the proximity of the whole joint capsule to the zona orbicularis, their anatomical relationship remains unclear. The zona orbicularis, which comprises the inner circular fibers of the joint capsule, is vital for hip stability in distraction.
