Ch. 13 Hip, Pelvis, and Thigh Injuries Study Guide

What type of joint is the hip joint?

Ball and Socket

The hip is the articulation point between what two bones?

Femur and Pelvis

The head of the femur sits into the cup-shaped part of the pelvis called what?

Acetabulum

What helps provide stability to the hip?

It’s deep and covered by ligamentous structures

What is the longest bone in the body?

Femur

Which muscles are part of the hip flexor group?

Rectus Femoris, Sartorius, and Iliopsoas

What muscles extend the thigh?

Hamstrings and Gluteus Maximus

Which motion is predominantly the result of contracting the lateral muscles which include gluteus medius, gluteus minimus, and the tensor fasciae latae?

Abduction

What are the primary groin muscles?

Gracilis, Adductor Magnus, Adductor Longus, and Pectineus

What’s a hip pointer?

Contusion of the iliac crest

What is the capital femoral epiphysis?

Where the neck of the femur joins the head

At what ages does an epiphyseal fracture typically happen?

Between 10 and 15

What will an athlete with hip bursitis report?

Snapping of the hip when they climb stairs

the growth plate between the neck and head of the femur

Epiphysis

injury that often results in an internally rotated leg

Hip dislocation

Femur fracture

injury that often results in an externally rotated leg

Head of femur

articulates with the acetabulum to form the hip joint

An area of the pelvis with little or no protection, the ______________ is easily bruised if it is not padded appropriately.

iliac crest

A severe quadriceps contusion can result in ____________________, which is the formation of bone within the muscle.

myositis ossificans

A __________________ results from a muscle pulling away from a bone, while a ______________ results from repetitive stress such as running.

avulsion; stress fracture

The condition known as __________________ is the result of disrupted blood flow to the head of the femur.

Legg-Calvé-Perthes disease

This condition of the hip can cause some snapping of soft-tissue structures, particularly around the greater trochanter: ___________________.

bursitis

Explain why muscle strains are common with groups such as the hip flexors and the hamstrings.

These muscles are two-joint muscles.

Explain how an AT should care for an athlete that is suspected to have a femur fracture.

A femur fracture should be immobilized, EMS should be contacted, and the athlete
should be transported to the hospital immediately.

Explain how an AT should care for a severe thigh contusion.

It is important to use the PRICES technique, and the knee should be flexed during the ice
application. The athlete should be examined by the team physician.
