Elbow joint

  

    . Elbow joint -   

          

     ( note - revision purpose only 👍 )    

                   

                   . Types and variety-  it is a synovial type of hinge variety joint            

    

         

    1.   Articulations -

                                 it is articulated  by three bones( Humerus, radius, and ulna), laterally it is articulate with the capitulum of humerus and head of radius by a bony structure, medially it is articulate with the trochlea of humerus and olecranon process of ulna        

                                 

                             

                 

               2.      Ligaments of elbow joint

                 

                                                   .  Capsular ligament

                                    

                                  .  Radial collateral ligament 

                                  .  Ulnar collateral ligament

                     . Capsular ligament -

  

                      

                                                 it covers the lower surface of the humerus on medially it is cover the radial fossa and laterally the coronoid fossa and posteriorly covered the olecranon  fossa, anteromedially it is attached the trochlear notch of the ulna except laterally

                     . Radial collateral ligament -

                                   

                                                    it is fan shape ligament and present on the lateral epicondyle of the humerus to the annular ligament and give origin to the supinator (muscles of extensor compartment )

                  .   Ulnar collateral ligament -

                                                   it is triangular shape present on the medial epicondyle of the humerus to the anterior, posterior and inferior part of the proximal ulna and give origin for the pronator teres and mostly flexor compartment muscles 

                            

             3.  Relations and Movement 

             

                                . Anteriorly - 

                                                       Brachialis, median nerve, brachial artery, and tendon of biceps brachii

                               . Posteriorly -

                                                        triceps and anconeus 

                               . Medially -      ulnar nerve and artery, common flexors 

                              . Laterally -     supinator and common extensor 

            4.  Movement and nerve supply 

                      .   Flexion -  biceps, and brachialis 

                      .   Extension- triceps brachii anconeus 

                      .   Nerve supply -

                                                           the median nerve, ulnar nerve, radial nerve, and musculocutaneous nerve

            

             APPLIED ASPECT 

  

                        Tennis elbow -

 it is caused by repeated movement of extensor muscles and pain is produced on the lateral side of the elbow joint (mostly brachioradialis muscles is affected )

        

       '   Trick for remember elbow joint '

                         do your movement of the elbow joint and recognized and feel the movement of joint (bone)  and contraction of muscles......
