  • History of “rolling over” the ankle
  • ATFL most commonly injured

Types

  1. High ankle sprain 10%: syndesmosis injury
  2. Low ankle sprain 90%: ATFL and CFL injury

Examination

  1. Swelling, Ecchymosis, Tenderness
  2. Anterior drawer test >5 mm
  3. Talar tilt test >5-10 degrees >30 all three lateral ligaments are ruptured

Complications

Q

Patient presented with lateral ankle pain. Hx previous ankle sprain. 🔑

A

PERONEAL TENDINOPATHY

Causes

  1. Tenosynovitis or rupture (Repetitive forceful eversion)
  2. Ankle subluxation or dislocation (Skiing injury)

Examination

  1. Pain and weakness with resisted dorsiflexion and eversion
  2. Weakness with the inability to actively evert the foot
  3. US may help visualize peroneal tendon subluxation over the lateral malleolus

Treatment

Q

Foot strikes the ground instead of the ball in soccer or an extra point in football. Diagnosis, 3 Complications, Test, Management In case of no trauma, what is the most likely diagnosis for medial ankle pain?

A

DELTOID LIGAMENT SPRAIN

Mechanism of Injury

  • Foot strikes the ground instead of the ball in soccer or an extra point in football.
  • Pure eversion is rare (Medial ankle ligaments are stronger than lateral ankle ligaments)

Grading Scale

Grade 1: Stretch

Grade 2: Stretch partial tear

Grade 3: Full tear

Examination

  • Medial foot swelling and ecchymosis
  • Pain on eversion
  • Negative anterior drawer test
  • Positive eversion test

Imaging

  • X-rays with AP, lateral, and oblique views
  • MRI if indicated

Treatment

  • Same as lateral ankle injuries
  • Immobilization for 4 to 6 weeks
  • Molded shoe orthosis for 4 to 6 months
  • Surgery if conservative measures fail

Complication

  • Syndesmosis ankle injury and Maisonneuve fractures

Q

Patient with medial foot pain after planterflexion. Hx ankle sprain.

A

TIBIALIS POSTERIOR TENDINOPATHY

Anatomy

  • Origin: Interosseous membrane and the posterior surface of the tibia and fibula
  • Insertion: Tuberosity of the navicular, cuboid, and base of the second to fourth metatarsals

Function

  • Plantar flexes the ankle and inverts the foot
  • Maintains the medial longitudinal arch

Mechanism

  • Tenosynovitis or tendon rupture (Repetitive forceful inversion)

Examination

  • “too many toes” in case of rupture
  • Weakness with inversion and plantar flexion

Treatment

  • Acute: Same as lateral ankle sprains
  • Conservative: Rehabilitation, orthotics to address pronation
  • Surgical: Tendon transfer, excising the accessory navicular

A

TIBIOFIBULR SYNDESMOSIS INJURY

Function

  • Maintain the integrity of the ankle mortise.
  • Resist forces that attempt to separate the tibia and fibula

Mechanism

  • Hyperdorsiflexion and forceful eversion of the ankle
  • Direct blow to the foot with the ankle held in external rotation

Presentation

  • High ankle sprain
  • Pain and swelling on the anterior aspect just above the ankle

Imaging

  • Mortise view: widening between the distal tibia and fibula

Q

Sudden push-off with the foot in the extension position (e.g., landing from a jump) Diagnosis of Heel Pain, Predisposing Factor, Test, Management

A

💡 Sudden push-off with the foot in the extension position (e.g., landing from a jump)

Achilles tendonitis

  • Repetitive eccentric overload causing inflammation and microtears of the tendon

Achilles tendon rupture

  • Inflammatory: Inflammation and degeneration causing a series of microtears
  • Vascular: Inadequate vascularization 2 to 6 cm proximal to the insertion of the tendon

Predisposing Factors

  • Training errors (Body - Equipment - Program)
    1. Sharp increase in mileage or intensity
    2. Change in recent footwear
  • Anatomic causes
    1. Tight hamstrings and Achilles tendons
    2. Pes cavus
    3. Genu varum
    4. Hyperpronation.
  • Increased age leads to an inflexibility of the tendon and decreased tensile strength

Examination

  1. Tendonitis
    1. Posterior ankle pain, swelling
    2. Pain elicited on push-off
  2. Achilles tendon rupture “any muscle rupture”
    1. Sudden audible snap with immediate swelling, ecchymosis
    2. Weakness in plantar flexion
    3. Positive Thompson’s test

Imaging

  • US may be helpful in differentiating partial from complete tear.

ER - POLICE - MS

Achilles Tendonitis

  1. EDUCATION: Relative rest
  2. PROTECTION: Short-term immobilization (splinting or bracing) for 2 weeks then might benefit from heel lifts
  3. LOADING: Stretching and strengthening (eccentric strength exercises)
  4. MEDICATION: Do not inject corticosteroids into the Achilles tendon → risk of rupture

Achilles tendon rupture

  1. EDUCATION: Complete rest
  2. PROTECTION
    • Nonweight bearing with crutches
    • CAM boot for 8-12 weeks → Increase dorsiflexion
  3. LOADING: Stretching and strengthening start at 2 weeks
  4. SURGERY:
    • Tendon repair for active individuals
    • Flexion dial lock brace for 2 to 6 weeks

Q

Planter fasciitis, mechanism, risk factors 🔑, management

What is the gold standard method of diagnosing plantar fasciitis? 🔑

A

Increased tension on the plantar fascia leads to chronic inflammation

  1. Pes cavus (high arch)
  2. Pes planus (flat foot)
  3. Obesity
  4. Tight Achilles tendon
  5. Heel spurs may contribute to the etiology (50% to 75%)

Examination

  • Tenderness is observed over the medial aspect of the heel
  • Pain can be elicited by hyperextension of the great toe
  • Pain is worse in the morning or at the start of weight-bearing activities

Imaging

  • Plain films to assess for bony spur
  • Ultrasound. Measure thickness of fascia. (gold standard)

CR.POLICE.MS

Risk Factors

  1. Tight Achilles tendon
