The Thigh

CHAPTER 17

The Thigh, Hip, Groin, and Pelvis

OVERVIEW

The thigh is continually exposed to traumatic injuries with contusions and strains occurring more frequently. Because of its bony, ligamentous, and muscular arrangements, the hip joint is considered by many to be the strongest articulation in the body. Though seldom injured, it is subject to muscular strains, contractures, bursitis, degenerative diseases, and stresses on the epiphyseal and apophyseal growth plates.

Those individuals that work with athletes must have a thorough knowledge of the anatomy of the pelvis, hip, groin, and thigh area to adequately evaluate and manage the common sports injuries associated with this area. He/she must also be aware of possible conditions that may occur if injuries are mishandled.

LEARNING OBJECTIVES

After studying Chapter 17, the student will be able to:

Identify the bony anatomy of the thigh, hip, groin and pelvis.

Explain how to prevent injuries of the thigh, hip, groin, and pelvis.

Identify the muscles that control the movements of the thigh, hip, groin and pelvis.

Differentiate between the different grades of quadriceps contusions and explain how to treat each appropriately.

Explain appropriate emergency procedures for injuries that occur to the thigh, hip, groin, and pelvis.

KEY TERMINOLOGY

Acetabulum - Deep socket of the innominate bones that contains a fat pad and articulates with the head of the femur

Apophysis - Bony outgrowth in which major muscles make their attachments

Avascular necrosis - Death of an area or tissue due to a lack of blood supply

Ectopic bone formation - Bone formation occurring in an abnormal place

Hip pointer - Contusion to the iliac crest

Innominate bones - Composition of three bones that ossify and fuse together early in life; these three bones are the ilium, ischium, and pubis.

Myositis ossificans traumatica - Ectopic bone deposits in muscle that result from severe or repeated blows...
