Study Notes

Podiatric Surgical Emergencies

Key emergencies include gas gangrene, open fractures, compartment syndrome, necrotizing fasciitis, and neurovascular compromise.

Treatment of Open Fractures

Main treatment consists of incision and drainage, extensive lavage, followed by reduction and fixation.

Gustilo-Anderson Classification of Open Fractures

Class I: Clean wound ≤ 5 cm with soft tissue damage; requires coverage. Antibiotics: Ancef, Clindamycin, Aminoglycoside.
Class IIIB: Extensive soft tissue damage and contamination with no possibility of reapproximation.
Class IIIC: Similar to IIIB but with arterial damage requiring repair.

Foreign Body and Puncture Wound Treatment

Important factors include checking tetanus status, administering antibiotics, and performing aggressive incision and drainage with copious lavage.

Intermetatarsal Compartments of the Foot

Comprised of four compartments containing interossei muscles.

Compartments and Associated Muscles

Medial Compartment: Abductor hallucis.
Lateral Compartment: Abductor digiti minimi.
Superficial Central Compartment: Flexor digitorum brevis (FDB).
Deep Central Compartment: Adductor hallucis.
Calcaneal Compartment: Quadratus plantae and lateral plantar artery.
Dorsal Compartment: Extensor digitorum brevis (EDB) and extensor hallucis brevis (EHB).

Compartment Syndrome Symptoms

Notable signs encompass pain that is disproportionate and unmanageable with analgesics, paralysis, impassive pain in dorsiflexion, pulselessness, paresthesia, pressure, and pallor.

Beau's Line

A transverse nail groove indicating trauma.

Neuromas and Nerve Involvement

Intermetatarsal neuromas primarily affect the plantar digital nerves (not common digital nerves).

Ilfeld's Disease

Characterized by agenesis of the fibular sesamoid.

Vassal Principle

Aligns adjacent fractures after the initial fracture reduction as soft tissue is returned to normal positioning.

Displacement Tolerance

A maximum of 2 mm of displacement can be managed without needing open reduction and internal fixation (ORIF).

Post-Operative Readmission Criteria

Criteria for readmission include uncontrollable pain, nausea, need for medical monitoring, dizziness, or inability to ambulate.

Anesthetic for Cardiac and Asthmatic Patients

Etomidate is the preferred anesthetic.

Eikenholtz Stages of Charcot Neuropathy

Stage 0: Pre-charcot.
Stage 1: Fragmentation.
Stage 2: Coalescence.
Stage 3: Remodeling.

Phases of Wound Healing

Includes inflammatory, proliferative, and remodeling phases.

Phases of Inflammation

Involves an inflammatory response, repair and regeneration, and remodeling and maturation.

Bone Healing Stages

Inflammation, soft callus, hard callus, and remodeling constitute the healing process.

Types of Bone Healing

Primary (Haversian remodeling) and secondary (callus formation) healing.

Frykberg Classification of Charcot Neuropathy

Ranges from foot and metatarsophalangeal (MTJ) involvement to the calcaneus.

Diabetic Foot Ulcers Causes

Sensory, motor, and autonomic neuropathies are primary contributors.

Surgical Layers of Dissection

Involves skin, superficial fascia, deep fascia, periosteum, and bone.

Waldvogel and Lew Classification

Differentiates conditions like periostitis, osteitis, and osteomyelitis with specific definitions and characteristics for each.

Cierny-Mader-Penninck Classification

Utilizes anatomic stages from medullary infection to diffuse cortical and medullary canal infection along with physiologic stages reflecting host risk factors.

Johnson and Strom Stages of PTTD

Stages I through IV describe progressive symptoms including tenosynovitis, flexible and rigid deformities, and ankle valgus.

Conti Stages of PTTD

Progresses from tenosynovitis with fine splits to complete rupture with scar tissue formation.

Arterial Occlusion Stages

Includes intermittent claudication, rest pain, and ischemia/gangrene.

Anesthesia in Foot Procedures

Ankle blocks utilize various nerves including the tibial and saphenous nerves; hallux blocks focus on proper digital nerves; Mayo blocks include medial plantar/medial dorsal nerves.

Neuromas and Symptoms

Neuromas are usually found plantar to the deep transverse intermetatarsal ligament; Sullivan's Sign indicates adjacent toes may spread apart with weight-bearing.

Tibial Nerve Branches under Lacinate Ligament

Divides into medial plantar, lateral plantar, and medial calcaneal nerves.

Suture Material Characteristics

Absorbable sutures range from cat gut to PDS; minimally absorbable options include silk and stainless steel with varied reactivity and strength characteristics.

Heloma Molle

Commonly occurs in the 4th interspace due to pressure from adjacent phalanges, producing a hyperkeratotic lesion.

Fracture Tension Side

Tension during healing is managed on the plantar side of metatarsal fractures.

Anesthetics in Cardiac Patients

Isoflurane is recognized as the safest inhaled anesthetic option.
