Description : Check out this medical PowerPoint presentation titled "Lateral and Medial Epicondylitis” by Ian S Rice MD.

This medical PowerPoint presentation is about lateral and medial epicondylitis, two conditions that involve pain and inflammation of the tendons that attach to the elbow.

Lateral epicondylitis, also known as tennis elbow, is a condition that affects the tendons on the outside of the elbow. It is commonly caused by overuse or repetitive strain on the forearm muscles and tendons, resulting in small tears in the tendons that attach to the lateral epicondyle (the bony bump on the outer part of the elbow). Symptoms of lateral epicondylitis include pain and tenderness on the outer part of the elbow, weakness in the wrist and forearm, and difficulty gripping objects.

Medial epicondylitis, also known as golfers elbow, is a similar condition that affects the tendons on the inside of the elbow. It is caused by overuse or repetitive strain on the forearm muscles and tendons, resulting in small tears in the tendons that attach to the medial epicondyle (the bony bump on the inner part of the elbow). Symptoms of medial epicondylitis include pain and tenderness on the inner part of the elbow, weakness in the wrist and forearm, and difficulty gripping objects.

Treatment for both lateral and medial epicondylitis typically involves rest, ice, and anti-inflammatory medications to reduce pain and inflammation. Physical therapy and exercises to strengthen the forearm muscles and tendons may also be recommended. In severe cases, surgery may be necessary to repair the damaged tendons. It is important to consult a healthcare professional if you are experiencing symptoms of lateral or medial epicondylitis.

History First described in 1873 by Runge Tendinosis not inflammatory condition Affects common attachment of extensor muscles of forearm to lateral epicondyle of humerus Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64 Van Hofwegen, C., et al. (2010) Clin Sports Med 29: 577-97

Epidemiology Incidence 1%-3% adults per year in UK 10-50% of people who play tennis regularly, Male > Female Lateral 4-7 times more common than Medial 35 – 55 years of age Male = Female in general population Dominant arm > Non-dominant Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64 Van Hofwegen, C., et al. (2010) Clin Sports Med 29: 577-97

Anatomy Common Extensors: Extensor Carpi Radialis Brevis* Extensor Carpi Radialis Longus Extensor Digitorum Extensor Carpi Ulnaris Radial  superficial sensory + deep  PIN Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64 Van Hofwegen, C., et al. (2010) Clin Sports Med 29: 577-97

Anatomy Radial Collateral Ligament Lateral Ulnar Collateral Ligament Annular Ligament
Slide 8-

Biomechanics: Extensor Group Eccentric contraction of ECRB Excessive/repetitive use extensors or supinator Tennis, typing, piano, manual work Risk factors in racquet sports: Incorrect technique Extended duration of play Frequency of play Size of handle Racquet weight Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64
Slide 9-

Pathophysiology Paucity of inflammatory cells Gross: Grayish, homogenous, edematous and friable tissue Tendinosis  degenerative process Rate of stretching exceeds tolerance  microtears  tendinosis Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64 Van Hofwegen, C., et al. (2010) Clin Sports Med 29: 577-97
Slide 10-

Histologic Stages of Microtrauma 1: Acute inflammatory response Sometimes resolves 2: Angiofibroblastic hyperplasia (increased concentration of fibroblasts, vascular hyperplasia, disorganized collagen) Hypercellularity in both organized and unorganized fasion Most common stage of presentation for treatment 3: Structural failure of tendon with partial of complete rupture 4: Features of stage 2 or 3 plus fibrosis, soft calcification within collagen and hard osseous calcification Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64

Slide 13-

Pathophysiology: Microscopy Angiofibroblastic hyperplasia meets normal tendon Kraushaar, BS, et al. (1999) J Bone Joint Surg. 81A(2): 1158-64
Slide 14-

Pathophysiology: Other Theories Stress shielding certain sections of tendon leading to structural weakening Shear forces leading to fibrocartilaginous composition of ECRB attachment  weak attachment  tendinosis Long muscle contraction rendering tendon avascular  free radicals Hyperthermic injury Protein kinase  apoptosis Altered gene expression and imbalance of matrix metalloproteinases and growth factors Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64
Slide 15-

Pathophysiology: Neurologic Changes High variability of patient’s symptoms Increased concentration neurotransmitters (glutamate), which sensitize pain response and direct irritation by lactate Cascade of changes in PNS neurons, which leads to sensitization of CNS May explain associated neck pain in 56% of patients Could be other overuse or altered biomechanics Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64
Slide 16-

Diagnosis: History Pain at lateral epicondyle Radiates down extensor mass, occasionally proximally Exacerbated by contraction of extensor mass Insidious onset History of repetitive activity or overuse Inability to hold items Ahmed, Z., et al. (2013) Bone Joint J. 95-B: 1158-64
