Elbow Anatomy (2) Humeroulnar joint ______________ Trochlea of humerus _______________ Flexion (0 – 150) Extension (0)-some hyperextension(-5 to -15) Ligaments: _________________________ _________________________
Slide 6-

Elbow Anatomy (3) Radioulnar joint Not part of elbow but associated with __________________________ Supported by the annular ligament which binds the head of the radius to the radial notch of the ulna forming the joint ___________________________
Slide 7-

Muscular Anatomy ______________________ Brachioradialis (flexion with arm neutral) Brachialis (flexion w/ pronation) ______________________ Pronator Group (pronation) ______________________ http://images.main.uab.edu/healthsys/ei_0153.jpg - biceps attachment

Bursa, Blood and Nerve Supply Bursa- _____________________ Blood supply Brachial artery ___________ ___________ Nerve supply Brachial plexus extends into the radial and ulna nerve***
Slide 10-

Prevention of Injuries General muscular condition Restrict pitching/ teach proper form Make sure equipment is proper (ie: racquet)- grip size, racquet weight Teach shoulder roll method of falling- example volleyball players rolling after a dig
Slide 11-

Contusions MOI: Direct contact HOPS __________________________________ Limited range of motion TX Rule out fracture first Ice, wrap and pad area Avoid aggressive stretching and strengthening Watch for ectopic bone formation ________________________________
Slide 12-

Olecranon Bursitis Olecranon bursa is largest in elbow MOI: fall on bent arm, leaning on elbow for long periods, infection HOPS ____________________________ Tx: ice, compression, pad area If associated with fever: refer _____________________________

Slide 14-

Elbow Sprains (1 – UCL) MOI: valgus force, repetitive stress HOPS: Pain over medial joint especially in cocking phase or acceleration phase of throwing Point tenderness over joint line ____________________________________ ____________________________ Tx: rest, general strengthening of flexors/ pronators; _________________________ ________________________________

Elbow Dislocations MOI: ____________________________ ______________________________, falling on outstretched hand HOPS Obvious deformity Snapping or cracking sensation Severe pain Forearm in flexion and appears shortened Tx: immobilize and refer MED EMERGENCY Check neurovascular status

Slide 18-

Medial Epicondylitis ______________________________ MOI: repetitive tension or valgus forces on the arm HOPS- Swelling, ecchymosis over medial epicondyle Pain aggravated by pronation and resisted flexion of wrist _________________________________ Tx: RICE, Strengthening/Stretching, look at technique

Slide 20-

Lateral Epicondylitis __________________ Most common overuse injury in the adult elbow MOI: _______________________ ______________________ Precursor: too large tennis racquet, gripping racket too tightly, excessive string tension, faulty mechanics
Slide 21-

Lateral Epicondylitis (2) HOPS Pain over lateral epicondyle Pain with resisted wrist extension + tennis elbow test Tx RICE __________________________________ _________________________ Counter force brace

Impingement of Ulnar nerve Ulnar nerve passes behind humerus in ulnar groove _______________ HOPS _________________ Can be caused from a medial elbow injury “crazy bone” or “funny bone” Tingling and numbness in ring and little finger __________________ Refer if chronic
Slide 24-

Strength Testing Elbow flexion Elbow extension Wrist flexion and extension Pronation Supination
Slide 25-

Stress Tests Valgus (UCL)/Varus (RCL) stress test – Positive Sign is laxity Tennis Elbow test-(Lateral Epicondylitis) - Positive Sign is increased pain Tinel’s sign (Ulnar nerve) – Numbness, Tinkling into Ulnar nerve region.
