The Digestive System

The digestive system is responsible for the ingestion, digestion, absorption, and elimination of food. It transforms food into nutrients through three main processes:

1. Mechanical Digestion: Chewing, grinding, crushing, and mixing of food to break it down into smaller pieces.
2. Chemical Digestion: Digestive juices break down macromolecules in food into smaller molecules that can be absorbed.
3. Absorption: Nutrients are absorbed into the bloodstream and transported to cells throughout the body.

Ingestion

Ingestion begins when food enters the mouth. Key steps include:

• Mastication (Chewing): Teeth tear and break food into smaller pieces.
• Salivation: Saliva mixes with food, forming a bolus and aiding in swallowing.
• Swallowing: The tongue

Shoulder Injuries and Conditions

Glenohumeral Subluxation

Excessive translation of the humeral head without complete separation from the joint. May occur anteriorly, posteriorly, or inferiorly (most common is anterior).
Mechanism of Injury (MOI): Forced abduction and external rotation; direct blow to shoulder

Anterior Glenohumeral Dislocation

Head of humerus is forced out of its articular capsule past the glenoid and downward to rest under the coracoid process.
Injuries: Torn capsular and ligamentous tissue, possible rotator cuff and/or long head biceps tendon avulsion, possible injury to brachial plexus, possible tear (almost always a labral tear).
MOI: Direct impact to posterior shoulder, forced abduction and external rotation

Bankart Lesion

Detachment... Continue reading "Shoulder Injuries and Conditions: A Comprehensive Guide" »

Shoulder Anatomy and Injury Mechanisms

Step Deformity

The distal end of the clavicle lies superior relative to the acromion process. This is a typical sign of an AC (acromioclavicular) sprain or dislocation.

Scapulohumeral Rhythm Explained

This refers to the movement of the scapula relative to the movement of the humerus throughout the full range of abduction. It occurs in distinct phases:

• 0-30 degrees of humeral abduction: No scapular movement (setting phase).
• 30-90 degrees of abduction: 2 degrees of humeral elevation = scapular abduction and upward rotation of 1 degree (2:1 ratio).
• 90-180 degrees of abduction: 1 degree of humeral elevation = scapular abduction and upward rotation of 1 degree (1:1 ratio).

Static Scapular Winging

The medial border of... Continue reading "Shoulder Injury Essentials: Deformities, Fractures, Sprains" »

Pelvis Lumbar Spine

Facet joint dysfunction—dislocation, subluxation, or degeneration of the facet. Localized pain over the facet, decrease in symptoms with the increase in activity Treatment options—injection (steroid to reduce inflammation), facetectomy (surgical resection of a vertebral facet).

Spondylopathies

Spondylolysis—defect in the pars interarticularis. “collared scotty dog”; localized low back pain that restricts extension. Spondylolisthesis—can be progression of spondylolysis. Separation of vertebra; “decapitated Scotty dog”. S&S: spondylolysis begins unilaterally. Pain and persistent aching, low back stiffness with increased pain after activity, frequent need to change position, full rom w/ some hesitation in regards...

Lumbar Spine & Pelvis

Sacralization

L5 becomes fused to the sacrum (essentially only 4 lumbar vertebrae; usually asymptomatic). Movement is only available in the 4 lumbar vertebrae.

Lumbarization

S1 fails to unite with the remainder of the sacrum (like a 6th lumbar vertebra; common in ~10% of the population).

Lordosis

Exaggerated curvature in the lumbar spine (butt out, chest out, anterior pelvic tilt).

Kyphosis

Exaggerated curvature in the thoracic spine (has forward head so that you aren’t looking down at the ground all the time).

Scoliosis

Lateral curvature of the spine

• C-shape: thoracic spine
• S-shape: lumbar spine; may compensate for curvature in thoracic spine to remain upright.

Low Back Muscle Strain

Stretch or tear in one or more of the paraspinal... Continue reading "Lumbar Spine & Pelvis Conditions: Causes, Symptoms & Treatment" »

Thigh, Groin, and Hip Conditions

Hip Dysplasia

Abnormal articulation between the femoral head and acetabulum. Often associated with an irregularly developed pelvis; coxa vara/valga. Can cause pain leading to hip subluxation or dislocation. May be congenital or developmental (DDH).

Risk factors:

• Being female
• Firstborn
• Born breech
• Family history of hip dysplasia
• Swaddling

Quad Contusion

Mechanism of Injury (MOI): Direct blow to thigh musculature.

• Grade 1: Superficial intramuscular bruise that produces mild hemorrhage.
• Grade 2: Deeper intramuscular bruise.
• Grade 3: Moderate intramuscular bruise.
• Grade 4: Deep intramuscular bruise that may split the fascia latae, allowing the muscle to protrude (muscle herniation).

Potential complication: Myositis ossificans.... Continue reading "Common Hip, Groin, and Thigh Injuries" »

Common Knee Injuries

Knee Plica

Fetal knee development involves three chambers that typically merge into one. The internal walls (plica) separating these chambers may persist. While often asymptomatic, the medio-patellar plica is most prone to causing issues. Symptoms can mimic meniscus injury, leading to catching and locking sensations.

Patellar Subluxation and Dislocation

Occurs at the patellofemoral joint, with lateral dislocations being the most common.

Knee Joint Dislocation

Occurs at the tibiofemoral joint and often involves tears of the MCL, ACL, LCL, and joint capsule.

Patellar Tendon Rupture

A complete tear of the quadriceps or patellar tendon, typically at its attachment to the patella.

Medial and Lateral Collateral Ligament Injuries

• Medial
