Orthopedic Emergencies and Urgencies, 59 pages (slides)

SLIDE TOPICS, SUBTOPICS and CONTENTS:

Orthopedic Emergencies and Urgencies
Rodney S. Gonzalez
MAJ, MC, USA
Family Medicine/Sports Medicine
Chief, Department of Warrior Care
Martin ACH, Ft. Benning, GA
Objectives
Define orthopedic urgencies and emergencies
Determine whether or not to evacuate
Acute management issues
Front-line treatment of orthopedic injuries
Definition
A
musculoskeletal injury or condition that, if missed, could result in
additional complications, significant impairment, or death
Orthopedic Emergencies
Open Fractures or Joints
Neurovascular Injuries
Dislocations
Septic Joints
Open Fractures
An
open (or compound) fracture occurs when the skin overlying a fracture
is broken, allowing communication between the fracture and the external
environment
Open Fractures- Classifications
Compound from within (inside-out):
The broken end of the bone breaks through or pierces the skin
Compound from without (outside-in):
External violence causes laceration or tissue trauma
Higher likelihood of contamination
Open Fractures- Classifications
Type I:
Small wound (<1cm), usually clean; low energy
Type II:
Moderate wound (>1cm), minimal soft tissue damage or loss; low energy
Type III:
Severe skin wound, extensive soft tissue damage; high velocity

Open Fractures- Complications
Soft tissue infection
Osteomyelitis
Gas gangrene
Tetanus
Crush syndrome
Skin loss
Non-union
Open Fractures- Management
DOs:
Control the bleeding
Cover with sterile dressing
Splint
IV antibiotics
Tetanus prophylaxis
Anti Gas Gangrene Serum (AGGS, Clostridium perfringes)

DON’Ts:
Scream and pass out
Replace protruding bone
Explore wound
Clamp vessels
One more thing…
Any open wound over or near a joint should be assumed to extend to the joint until proven otherwise

Neurovascular Injuries
Vascular trauma
Trauma to peripheral nerves
Acute compartment syndrome
Neurovascular- Etiology
Fracture
Humerus, femur
Dislocation
Elbow, knee
Direct/penetrating trauma
Embolism
Direct Compression
Cast, unconscious
Nerves- Lower Extremity
Nerves- Upper Extremity
Acute Compartment Syndrome
An injury or condition that causes prolonged elevation of interstitial tissue pressures
Increased pressure within enclosed fascial compartment leads to impaired tissue perfusion
Prolonged ischemia causes cell damage which leads to increased vessel permeability
Plasma leaks into interstitium causing further increase in compartment pressure
Extensive muscle and nerve death >8 hours
ACS- Etiology
Direct blow or contusion
Crush injury
Burns
Snake bites
Fractures
Hematoma
Prolonged pressure
ACS- Findings
5 Ps
Pain
Paresthesias
Paralysis
Pulses
Palpation
Severe pain
Pain with stretch
Tense compartment
Tight, shiny skin
Late findings
Paresthesias
Paralysis
Loss of pulses

ACS- Anatomy
Upper Extremity

Hypothenar
Adductor
Interosseous
Carpal canal
Finger
ACS- Anatomy

Anterior
Extensor hallucis longus
Extensor digitorum longus
Peroneus tertius
Tibialis anterior
Deep peroneal nerve
Anterior tibial artery
Lateral
Peroneus longus
Peroneus brevis
Superficial peroneal nerve
Superficial posterior
Gastrocnemius
Soleus
Sural nerve
Deep posterior
Flexor digitorum longus
Flexor hallucis longus
Posterior tibialis
Posterior tibial nerve
Posterior tibial artery
Peroneal artery
ACS- Final Thought

Always check neurovascular status after moving patient, manipulating
injured limb, before and after applying cast or splint, and at frequent
intervals if transfer is delayed.

Dislocations
Displacement of bones at a joint from their normal position
May be associated with neurovascular injury
Dislocation- Shoulder
Most common major joint dislocation
May be associated with:
Bankart lesion
Fracture dislocation
Hill sachs lesion
SLAP lesion
Rotator cuff tear
Nerve injury- axillary, posterior cord, musculocutaneous
Dislocation- Shoulder
Anterior (95%)
Arm abducted and externally rotated
Posterior (2-4%)
Arm adducted and internally rotated
Electrocution, seizure
Inferior (1%)
Hyperabduction
Usually associated with significant trauma
Dislocation- Knee
Anterior (31%)
Caused by hyperextension
Often ACL and PCL both torn
MCL and/or LCL usually injured
Popliteal artery- intimal tear
Posterior (25%)
ACL and PCL torn
Possible tear of extensor mechanism
Avulsion or disruption of popliteal artery
Lateral (13%)
Medial (3%)
Rotary (4%)- usually posterolateral
Dislocation- Knee
Injury to popliteal artery and vein is common
Peroneal nerve injury in 20-40% of knee dislocations
With peroneal nerve injury, suspect vascular injury
Dislocation- Elbow
Second most common major joint dislocation
Usually closed and posterior
Fall on extended elbow
Posterior, posterolateral, posteromedial, lateral, medial, or divergent

Complex- dislocation with fracture (35-40%)
Radial head fracture most common
Simple- dislocation without fracture
Rupture
of capsule, rupture of MCL and lateral ligaments, rupture of flexor
pronator mass, possible injury to brachialis muscle and rupture of
brachial artery
Dislocation- Elbow
Nerve inury
Neuropraxia involving median or ulnar nerve in 20% of elbow dislocations
Ulnar nerve palsies more common in pediatric
Most neuro deficits are transient
Dislocation- Sternoclavicular
Anterior
More common
Traumatic or atraumatic
Posterior
Rare
Soft tissue swelling may give false impression of anterior dislocation
Up to 25% complication rate
Hemorrhage, tracheal or esophageal injuries, pneumothorax
Dislocation- Hip
Usually high-energy trauma
More frequent in young patients
Anterior- hip in external rotation
Posterior- hip in internal rotation
Central acetabular fracture dislocation
May result in avascular necrosis
Sciatic nerve injury in 10-35%

Septic Joint/Septic Arthritis
Inflammation of a synovial membrane with purulent effusion into the joint capsule
Usually monoarticular
2-10 cases per 100,000 in general population
Gonococcal vs nongonoco
