Study Notes
Orthopedic Emergencies
- Key orthopedic emergencies include open fractures, subluxations and dislocations, and neurovascular injuries.
Neurovascular Injuries by Fracture Type
- Anterior shoulder dislocation can injure the axillary nerve, axillary artery, and musculocutaneous nerve.
- Humeral shaft injuries primarily affect the radial nerve.
- Medial epicondylar fractures may injure the ulnar nerve.
- Supracondylar fractures and elbow dislocations can damage the brachial artery, radial nerve, ulnar nerve, and median nerve.
- Hip dislocations mainly affect the femoral nerve.
- Knee dislocations can injure the popliteal artery, peroneal nerve, and tibial nerve.
- Lateral tibial plateau fractures often involve the peroneal nerve.
Signs of Neurovascular Complications
- Indicators include decreased motor function, capillary refill issues, numbness, tingling, and paresthesia.
Situations Requiring Orthopedic Consultation
- Conditions include compartment syndrome, irreducible dislocations, circulatory compromise, open fractures, and injuries needing surgical intervention.
Cauda Equina Syndrome Symptoms
- Signs include incontinence, focal lower extremity weakness, and subtle paresthesia.
Medications for Procedural Sedation
- Common agents include propofol, morphine/versed, dilaudid/valium, and ketamine.
Acute Pain Management
- IV options include morphine, dilaudid, fentanyl, and toradol.
- Oral options include hydrocodone, oxycodone, tramadol, and NSAIDs.
Open Fractures
- Defined as compound fractures where skin and soft tissue injury allows communication with the fracture hematoma.
- Associated concerns include infection and poor vascular supply.
Gustilo-Anderson Classification for Open Fractures
- Type I: 10 cm opening, comminuted/segmental fractures.
- Type IIIa: Minimal soft tissue damage with a large wound.
- Type IIIb: Severe periosteal stripping and bone exposure with massive contamination.
- Type IIIc: Associated major vascular injury.
Management of Open Fractures
- Evaluate soft tissue injury, extremity quality, and vascular status during physical examination.
- Initial treatment focuses on removing large foreign bodies, copious irrigation, splinting, IV antibiotics, and tetanus vaccination.
- Avoid exploration of the wound and removal of bone fragments initially.
Tetanus-Prone Wound Characteristics
- Features include being larger than 2 cm, having a stellate pattern, gross contamination, or being greater than 12 hours old.
Tscherne Classification for Closed Fractures
- Classification ranges from negligible soft tissue injury (Type 0) to extensive crush injury with possible compartment syndrome (Type 3).
Osteomyelitis
- Defined as infection of bone leading to inflammatory destruction and new bone formation.
- Common in dialysis patients at the spine and ribs, in IV drug users at the clavicles, and in diabetics at the foot and ulcers.
Mechanisms of Spread for Osteomyelitis
- Includes hematogenous spread, contiguous spread from nearby infections, and direct inoculation due to injury or surgery.
Diagnosis and Treatment of Septic Joints
- Commonly affected joints: knee, hip, elbow, ankle, sternoclavicular joint.
- Diagnosis involves imaging, fluid aspiration for culture, and lab markers such as elevated WBC, ESR, and CRP.
- Treatment involves joint fluid aspiration and directed antibiotic therapy.
Compartment Syndrome
- Resulting from pressure exceeding capillary perfusion, leading to muscle and nerve injury.
- Etiologies include fractures, crush injuries, and burns.
- Key indicators (the five P's): pain, paresthesia, pallor, paralysis, pulselessness; pain and paresthesia are early signs.
Fat Embolism Syndrome (FES)
- Occurs predominantly after pelvic or long-bone fractures, presenting with pulmonary distress, mental status changes, and petechial rash.
- Prevention strategies focus on early stabilization and operative treatment.
- Main treatment is supportive care, similar to ARDS management.
