Pelvis, Hip, and Thigh Conditions Chapter 14 Pelvis Sacrum Coccyx Innominate bone Ilium Ischium Pubis Collectively protect the inner organs, bear weight, site of muscular attachments. Sacroiliac Joints Help bear weight Provide elasticity to pelvic ring Iliac articulation covered in fibrocartilage Sacral articulation covered in hyaline Sacrococcygeal Joint Usually a fused junction United by a fibrocartilaginous disc Pubic Symphysis Cartilaginous joint with a disc of fibrocartilage called the interpubic disc Spreads Compresses Rotates Femur Strongest and longest bone in the body Weakest link is the surgical neck Angles at 125° in the frontal plane The hip joint Acetabulum of the pelvis=socket Head of the femur=ball Both surfaces covered in cartilage Acetabulum has a U-shaped cartilage structure known as the acetabular labrum Hip joint capsule Coxofemoral joint is large and loose Capsular fibers encircle the neck giving it great stability Ligaments of the Hip Joint Ligament of Bigelow AIIS-Femur Pubofemoral ligament Isciofemoral Ligamentum teres Occurs within the joint Inguinal ligament ASIS-pubic symphysis Femoral Triangle Inguinal ligament Sartorius Adductor longus Femoral nerve, artery, and vein all exist within Bursae Iliopsoas – Iliopsoas and the articular capsule Trochanteric – Greater trochanter and the gluteus maximus Gluteofemoral – Gluteus maximus from the vastus lateralis Ischial – Iscial tuberosity from the gluteus maximus Q-Angle Angle between the quads and the tibial tuberosity Lines drawn between ASIS and patella and between patella and tibial tuberosity Generally 13° in males Generally 18° in females Muscles-Flexion Iliopsoas Rectus femoris Pectineus Sartorius Tensor fasciae latae Muscles-Extension Gluteus maximus Biceps femoris Semitendinosus Semimembranosus Adductor magnus Muscles-Abduction Gluteus medius Gluteus minimus Tensor fasciae latae Sartorius Piriformis Muscles-Adduction Pectineus Adductor brevis Adductor magnus Adductor longus Gracilis Muscles-Medial Rotation Gluteus medius Gluteus minimus Tensor fasciae latae Muscles-Lateral Rotation Piriformis Obturator internus Obturator externus Superior gemelli Ingerior gemelli Quadratus femoris Gluteus maximus Nerves Lumbar plexus First four lumbar nerves Sacral plexus L4-S4 nerves Physical conditioning Flexibility and strengthening of all overlapping muscle groups Presentation guidelines What is the injury? Show pictures, videos, demonstrations to help us understand what is involved. How does it happen? Again pictures, videos, demonstrations to show how it happens. How do you treat it acutely? What is the long term treatment? What special procedures help this problem? Surgeries, immobilization, rehabilitation, mobilizations… Contusions Hip pointer Quadriceps contusion Myositis Ossificans Acute compartment syndrome Bursitis Greater Trochanteric Bursitis Iliopsoas Bursitis Ischial Bursitis Snapping Hip Syndrome Sprains and Dislocations Posterior-superior dislocation Strains Quadriceps Strain Hamstrings Strain Adductor Strain Gluteal Strains Piriformis Syndrome Vascular and Neural Disorders Legg-Calvé-Perthes Disease Venous Disorders Thrombophlebitis Phlebothrombosis Toxic Synovitis Obturator Nerve Entrapment Fractures Avulsion fractures Slipped capital femoral epiphysis Stress fractures Osteitis Pubis Displaced and Nondisplaced Pelvic fractures Sacral and Coccygeal fractures Femoral Fractures
