LIGAMENT
LOCATION
FUNCTION
Inferior Pubic Ligament   B/T inferior pubic rami   Strengthens inferior portion of pubic symphysis  
🗑
Superior Pubic Ligament   Attaches to pubic tubercles   Strengthens superior and anterior portions of pubic symphysis  
🗑
Iliolumbar Ligament   TVP of L5 to ala of sacrum   Limits rotation of L5 on S1. Prevents L5 from moving anterior on S1.  
🗑
Sacrospinous Ligament   Lower, lateral sacrum and coccyx (posterior), attaches to ischial spine   This along with the Sacrotuberous ligament converts the greater sciatic notch into a foramen for passage of the sciatic nerve  
🗑
Sacrotuberous Ligament   B/T PSIS & PIIS, posterior surface of sacrum & coccyx. Come together on ischial tuberosity   VERY STRONG, attachment for gluteus maximus, Prevents forward rotation of the sacrum  
🗑
Long Posterior Sacroiliac Ligament   B/T PSIS & Lower portion of sacrum   Prevents downward movement of sacrum  
🗑
Short Posterior Sacroiliac Ligament   B/T ilium & Upper sacrum on dorsal surface   Prevents forward movement of sacrum  
🗑
Interosseous Sacroiliac Ligament   Connects tuberosities of ilium to sacrum   STRONGEST  
🗑
Anterior Sacroiliac Ligament   Connects ala & pelvic surface of sacrum to auricular surface of ilium   Provides stability to the joint anteriorly  
🗑
Iliofemoral Ligament     Limits Hyperextension of Hip  
🗑
Pubofemoral Ligament   Acetabular labrum to superior ramus of pubis and neck of femur   Limits Hyperextension and abduction of hip  
🗑
Ischiofemoral Ligament   Ischial portion of acetabulum to femoral neck   Limits hyperextension and medial rotation of the hip  
🗑
Deltoid Ligament   Through calcaneus, navicular, talus, and attaches to the tibia   Helps support medial longitudinal arch  
🗑
Lateral Ligament   Calcaneus, Talus, and fibula   Provides support to the lateral longitudinal arch  
🗑
Spring Ligament   Calcaneus to Navicular   Supports medial side of medial longitudinal arch  
🗑
Long Plantar Ligament   Calcaneus, cuboid, base of 3-5 MT   Primary support of lateral longitudinal arch  
🗑
Short Plantar Ligament   Calcaneus to cuboid   Supports lateral longitudinal arch  
🗑
Plantar Aponeurosis   Calcaneus to proximal phalanges   Supports arches, keeps posterior segments from separating from anterior segments.  
🗑
Anterior Cruciate Ligament   From ant. tibia to post. femur   Provides support in sagittal plane, keeps femur from displacing posteriorly on tibia, tightens during extension  
🗑
Posterior Cruciate Ligament   From post. tibia to ant. femur   Provides stability in sagittal plane, prevents femur from displacing anteriorly on tibia, tightens during flexion  
🗑
Medial Collateral Ligament   Tibia and medial epicondyle and medial meniscus   Provides medial stability in the frontal plane  
🗑
Lateral Collateral Ligament   Fibula, lateral epicondyle   Provides lateral stability in the frontal plane  
🗑
Medial and Lateral Meniscus   Superior surface of tibia   Shock absorption, deepen joint surface  
🗑
Medial Collateral Ligament in elbow   Medial epicondyle of humerus to medial side of coronoid process and olecranon process   Provides medial stability  
🗑
Lateral Collateral Ligament in elbow   Lateral epicondyle of humerus to annular ligament and lateral ulna   Provides lateral stability  
🗑
Annular Ligament   Ant. and Post. to radial notch of ulna. Encompasses head of radius   Holds head of radius against ulna  
🗑
Radial Collateral Ligament   Styloid process of radius to scaphoid and trapezium   Provides lateral stability  
🗑
Ulnar Collateral Ligament   Styloid process of ulna to pisifrom and triquetrum   Provides medial stability  
🗑
Palmar Radiocarpal Ligament   Ant. surface of distal radius and ulna to anterior surface of proximal carpal bones and capitate in distal row   Thick, Tough, Limits wrist extension  
🗑
Dorsal Radiocarpal Ligament   Post. surface of distal radius to post. scaphoid, lunate and triquetrum   Limits wrist flexion  
🗑
Articular Disk   Distal end of ulna to triquetrum and lunate   Shock absorption, filler *ulna shorter than radius*  
🗑
Palmar Fascia   Palm of hand   Thick, provides protection for structures of the palm  
🗑
Flexor Retinaculum   Anterior surface   Holds flexor tendons against wrist, prevents carpal bones from separating  
🗑
Palmar Carpal Ligament   Part of flexor retinaculum, styloid process of radius and ulna   same as flexor retinaculum  
🗑
Transverse Carpal Ligament   Part of flexor retinaculum, Pisiform, hook of hamate (medially), Scaphoid, trapezium (Laterally)   Forms tunnel for tendons and median nerve *Carpal Tunnel*  
🗑
Extensor Retinaculum   Posterior, Styloid process of ulna medially, triquetrum, pisiform, and lateral side of radius   Holds extensor tendons close to wrist  
🗑
Costoclavicular Ligament   Clavicle to costal cartilage of 1st rib   Limits amount of clavicular elevation  
🗑
