Lumbar Triangle
The Lumbar Triangle, also known as Petit's Triangle, is an anatomical region located in the lower back. It is named after the French surgeon, Jean Louis Petit, who first described it in the 18th century.
Etymology[edit | edit source]
The term "lumbar" is derived from the Latin word "lumbus" meaning loin, and "triangle" from the Greek word "triangulum" meaning three-cornered. The Lumbar Triangle is named after Jean Louis Petit, a French surgeon who first described it.
Anatomy[edit | edit source]
The Lumbar Triangle is defined by three anatomical landmarks. The base is formed by the iliac crest, the posterior border by the latissimus dorsi muscle, and the anterior border by the posterior edge of the external oblique muscle.
Clinical Significance[edit | edit source]
The Lumbar Triangle is clinically significant as it is a potential site for the occurrence of lumbar hernia. A lumbar hernia can occur when there is a weakness in the muscular wall of the abdomen, allowing abdominal contents to protrude through the weak spot.
