2
The Hip and Pelvis
3
© 2010 Delmar, Cengage Learning 3 © 2011 Delmar, Cengage Learning Upon completion of this chapter, you should be able to: Explain the importance of the hip and pelvis as a support structure for the human body Describe the skeletal structure of the hip and pelvis List the primary muscles of the hip and pelvis Describe common injuries associated with the hip and pelvis 3
4
© 2010 Delmar, Cengage Learning 4 © 2011 Delmar, Cengage Learning The hip is one of the most stable joints in the body strongest joint in body Well protected and surrounded by muscle Freely movable, ball-and-socket joint Attachment site for these muscles: Back Abdomen Hamstrings & quads Abductors & adductors Gluteals 4
5
© 2010 Delmar, Cengage Learning 5 © 2011 Delmar, Cengage Learning The pelvis: Transmits weight from axial skeleton to lower limbs when standing, or to ischial tuberosities when sitting Provides attachments for various muscles that attach onto and control the lower limbs Houses parts of the digestive and urinary tracts Houses reproductive systems 5
6
© 2010 Delmar, Cengage Learning 6 © 2011 Delmar, Cengage Learning Ilium: upper & lateral sections of pelvis Sacrum: 5 fused vertebrae Ischium: between ilium & pubis; bears weight of body when sitting Pubis: to the front, below bladder Coccyx: tailbone 6
7
© 2010 Delmar, Cengage Learning 7 © 2011 Delmar, Cengage Learning Iliac crest: upper ridge of ilium Greater sciatic notch: space through which sciatic nerve passes Iliac fossa: concave inner surface of ilium Obturator foramina: large openings in ischium Symphysis: line where 2 sides of pubis are fused 7

9
© 2010 Delmar, Cengage Learning 9 © 2011 Delmar, Cengage Learning Hip flexors: Iliopsoas Sartorius Pectineus Rectus femoris Adductor muscles: A. longus A. brevis A. magnus 9
10
© 2010 Delmar, Cengage Learning 10 © 2011 Delmar, Cengage Learning Hamstring muscles & glutes: aid in hip extension 10
11
© 2010 Delmar, Cengage Learning 11 © 2011 Delmar, Cengage Learning Bursitis Commonly seen in athletes who do not sufficiently stretch and warm up the outside of the hip Symptoms: tenderness Treatment: limiting activity, stretching exercises, and ice massage, and nonsteroidal anti-inflammatory medicines (NSAIDs) 11
12
© 2010 Delmar, Cengage Learning 12 © 2011 Delmar, Cengage Learning Hip fracture Break of the top part of the femur where it connects to the pelvis Symptoms: severe hip pain Treatment: highly individualized 12
13
© 2010 Delmar, Cengage Learning 13 © 2011 Delmar, Cengage Learning Quadriceps and hip flexor strains Common in sports requiring jumping, kicking, or repetitive sprinting Treatment: icing, compression with an elastic wrap, and anti-inflammatory medications Rehabilitation: progressive and sport specific 13
14
© 2010 Delmar, Cengage Learning 14 © 2011 Delmar, Cengage Learning Hamstring strains Mild or moderate damage in the muscle tissue Completely tearing the muscles or separating them from connective tendons is a hamstring tear Symptoms: sharp pain in the back of the thigh, bruising, swelling, loss of strength, and hearing a “pop” Treatment: RICE, medication, and physical therapy and rehabilitation 14
15
© 2010 Delmar, Cengage Learning 15 © 2011 Delmar, Cengage Learning Adductor (groin) strains Common in sports requiring sudden sideways changes in direction Treatment: rest, ice, and anti-inflammatory medications, adductor stretching and strengthening exercises 15
16
© 2010 Delmar, Cengage Learning 16 © 2011 Delmar, Cengage Learning Iliotibial band syndrome Inflammation of iliotibial band Symptoms: irritation over the outside of the knee joint Treatment: rule out mechanical problems or training errors, proper footwear, icing the area of pain, and stretching 16
17
© 2010 Delmar, Cengage Learning 17 © 2011 Delmar, Cengage Learning Quadriceps contusions Usually caused by a direct blow to the thigh Treatment: compression, ice (applied during the first 24 to 48 hours), and crutches 17
18
© 2010 Delmar, Cengage Learning 18 © 2011 Delmar, Cengage Learning Myositis ossificans (calcium deposit) Usually the result of recurrent trauma to a quadricep muscle that was not properly protected after an initial injury Symptoms: hard, painful mass in the soft tissue of the thigh and progressive loss of bending motion of the injured knee Treatment: heat, limitation of joint motion, rehabilitative exercises within the limits of pain; surgery may be necessary 18

21
© 2010 Delmar, Cengage Learning 21 © 2011 Delmar, Cengage Learning Iliac crest contusion (“hip pointer”) Painful injury caused by a direct blow to the hip Symptoms: extreme tenderness, swelling, and ecchymosis over the iliac crest Treatment: ice and compression 21
22
© 2010 Delmar, Cengage Learning 22 © 2011 Delmar, Cengage Learning Overuse injuries Cumulative effect of very low levels of stress Include chronic muscle strains, stress fractures, tendonitis, “snapping hip” (iliopsoas tendon rolls over head of femur), and bursitis Treatment: rest and exercise different body parts (cross-training) 22
23
© 2010 Delmar, Cengage Learning 23 © 2011 Delmar, Cengage Learning Stress fractures: Pelvis stress fractures occur most often in runners and dancers Femur stress fractures usually occur in runners Symptoms: chronic, ill-defined pain over the groin and thigh Treatment: rest and nonweight-bearing endurance exercises 23
24

25
© 2010 Delmar, Cengage Learning 25 © 2011 Delmar, Cengage Learning The hip is a stable joint that is well protected and surrounded by muscle on all sides The pelvis is made up of several flattened bones that function as a support structure Injuries to the hip and thigh are very common in athletics 25
