The modern game of tennis, as well as its equipment, is attributed to the efforts of several individuals, but the most notable is Walter Clopton Wingfield, who patented a version of the game in 1874. He introduced the rules and equipment that closely resemble today's tennis. Wingfield's patent, titled "Sphairistikè," significantly influenced the development of lawn tennis, which gained popularity in the late 19th century. However, the formal codification of rules and regulations was later established by various tennis associations.

At the C7-T1 level, when it is stated that the spinal canal and neuroforamina are patent, it means that these structures are open and unobstructed.

This is a positive finding, suggesting normal anatomical conditions in that region.
