Pincer-Type Femoroacetabular Impingement

Pincer-type femoroacetabular impingement is an acetabular/pelvic-sided disorder. Although acetabular overcoverage is a common theme for this disorder, there are distinct pincer subtypes with variable pathomorphologies that must be considered when contemplating the ideal approach and treatment for these disorders. In addition, emerging evidence suggests that extra-articular pelvic structures, such as the anterior inferior iliac spine, may also result in hip impingement. The current chapter will describe the various pincer subtypes, their clinical presentation, and typical imaging findings. Arthroscopic indications, contraindications, specific arthroscopic surgical techniques, postoperative rehabilitation, and femoroacetabular impingement surgical outcomes will be discussed as well.
