Chapter 16

A baseball player sustains a contusion after being struck in the thigh by a line drive. Explain the management of this injury.

- ice in flexed position

A young boy with Legg-Calvé-Perthes disease can return to sports participation after 8 to 12 weeks of rest.

F

Abnormal ossification involving bone deposition within muscle tissue is called an exostosis

F

An individual with a mild quadriceps contusion will walk with a limp but will have only mild pain and swelling.

F

The Kendall test is used to assess iliotibial band tightness.

F

The femur angles laterally downward from the hip during the support phase of walking and running, enabling single-leg support beneath the body's center of gravity.

F

The quadriceps muscles are the most frequently strained muscles in the body.

F

Avascular necrosis of the proximal femoral epiphysis is called:

Legg-Calvé-Perthes disease

During the Thomas test, if the straight right leg rises off the table while the left thigh is brought to the chest, it indicates the presence of flexion contractures in the right iliopsoas muscle.

T

If an adolescent boy is unable to do internal rotation at the hip or stand on one leg without severe pain, a slipped capital femoral epiphysis should be suspected.

T

In an adductor strain, the athlete may report that running straight ahead and backwards does not cause pain.

T

Legg-Calvé-Perthes disease is an avascular necrosis of the proximal femoral epiphysis.

T

The hamstrings are important dynamic stabilizers of the knee and, therefore, strengthening exercises for this muscle group should be a major component of any hip or knee rehabilitation program

T

A rugby player is down on the field after receiving a severe blow to the anterior right thigh. The thigh is externally rotated and severely angulated. Swelling is present, and the athlete is in severe pain. Explain the immediate management for this injury

assess neuromuscular integrity treat for shock

The _____ bursa provides a cushion between the greater trochanter of the femur and the gluteus maximus.

deep trochanteric

In hip dislocation, when the head of the femur displaces in a posterior-superior direction, the leg typically rests in what position?

flexed and internally rotated

Avascular necrosis of the hip usually occurs at the:

head of the femur

The iliofemoral ligament prevents excessive:

hip extension

The zona orbicularis attaches to the femoral neck in a circular fashion and contributes to:

hip stability

It is not unusual to have severe bleeding after a femoral fracture lead to:

hypovolemic shock

Which of the following limits hip hyperextension?

iliofemoral ligament

Overdevelopment of which muscle(s) can lead to anterior pelvic tilt?

iliopsoas

A condition that may occur after a contusion to the quadriceps muscle group involving abnormal ossification of bone deposition within the muscle tissue is called:

myositis ossificans

A blood clot that travels through the circulatory system to lodge in a blood vessel in the lungs is called:

pulmonary embolism

An athlete experienced an acute muscular injury to the soft tissue of the anterior hip. Upon manual muscle testing, you find weakness upon hip flexion and knee extension. Based on results of manual muscle testing, which of the following is most likely?

rectus femoris strain

An avulsion fracture at the anterior-superior iliac spine may involve which muscle?

sartorius

In a femoral shaft fracture, the thigh appears:

shortened and externally rotated

Runners who cross the feet over their midline during running increase the Q-angle and can develop:

trochanteric bursitis

What is a hip pointer?

-type of contusion in the iliac crest over the TFL muscle associated with hematoma. -caused by a direct blow to the iliac crest most common in anterior and later part of the crest

All of the following are done to prevent formation of myositis ossificans, except:

PNF stretching during the acute phase

Which of the following is used to determine the severity of a hamstring strain?

active and resistive knee flexion

The weakest component of the femur is the:

femoral neck

Tenderness upon palpation of the ischial tuberosity may indicate

ischial bursitis avulsion fracture hamstring tendonitis

All of the following are frequent complaints with a stress fracture to the pubis or femoral neck except:

pain while using the flutter kick

An excessive Q-angle predisposes an individual to:

patella injuries

done to prevent formation of myositis ossificans

protective padding prior to sports re-entry cryotherapy thermotherapy during the subacute phase

The sacroiliac joints are:

synovial and syndesmosis joints

Acute inflammation of a vein is called

thrombophlebitis

Weakness of the gluteus medius is determined by:

Trendelenburg test

A contusion caused by direct compression to an unprotected iliac crest is referred to as:

a hip pointer
