Pelvis, Hip, and Thigh Conditions Flashcards
Pelvis Functions
Protects Organs
Transmits loads between trunk and lower extremity
Provides sites for muscle attachements
Pelvis fused bones
Sacrum
Coccyx
Ilium, Ischium, and Pubis
SacroIliac (SI) Joint
Critical Link between the two Pelvic Bones
Strong Ligamentous Support
Semi-Mobile Joint
Sacrococcygeal Joint
Fused Line Symphysis united by a fibrocartilaginous disc
Pubic Symphysis
Interpubic disc located between the two joint surfaces
Femur weakest point
Femoral Neck b/c its at a right angle
Angle of Inclincation
Angle of depression formed by a line drawn through the shaft of femur and a line passing through the long axis of the femoral neck
Approximately 125 degrees in the FRONTAL plane
Coxa Valga
> 125 degrees
Coxa Vara
<125 degrees
Angle of Torsion
Relationship between femorall head and femoral shaft in TRANSVERSE plane
Approximately 12 degrees
Anteversion
> 12 degrees
Retroversion
<12 degrees
Hip Joint
Head of femur and acetabulum of pelvis
Ball and Socket Joint
Very Stable
Hip Joint Capsule
Completly surrounds joint, attaching to the labrum of the acetabular socket
Passes over a fat pad internally to join to the distal aspect of the femoral neck
Ligaments of Hip Joint
Iliofemoral Ligament Pubofemoral Ligament Ischiofemoral Ligament Wide Ligament of Bigalow/Iliofemoral Ingunial Ligament
Iliofemoral Ligament
cut or repair with hip replacement
Limits hyperextension
Pubofemoral Ligament
Limits abduction and hyperextension
Ischiofemoral Ligament
Limits extension
Femoral Triangle Borders
Ingunial Ligament - Superior
Sartorious - lateral
Adductor Longus - medial
Femoral Triangle Contents
Femoral Nerves
Femoral Artery
Femoral Vein
Femoral Triangle Importance
1) Highly Palpable - supine with hip extension for pulse
2) Pressure Point - can contain leg bleeding at this point
Q-angle
Angle between line of resultant force produced by quadriceps and line of patellar tendon
Males - 13 degrees
Females - 18 degrees
Posterior Pelvic Tilt
Assists Hip Flexion
Anterior Pelvic Tilt
Assists Hip Extension
Lateral Pelvic Tilt
Assists Hip Abduction
Hip Pointer Contusion MOI
Direct blow to Iliac Crest
Common - anterior or lateral portion of crest
Hip Pointer Contusion S&S
Antalgic Gait with shortened swing phase
Increase pain with active trunk flexion and active hip flexion
Point tenderness; swellingl ecchymosis
Hip Pointer Contusion Management
Standard acute; rest; protect with hard-shell pad for return to activity
Quadriceps Contusion MOI
Direct Blow
Common - Anterolateral Thigh
Quadriceps Contusion S&S
Transitory loss of function
With continued play, progressively stiffer and unresponsive
