Q

management for ACL tear

A
  1. Initial
    - RICE with knee immobilizer brace, +/- crutches
    - acetaminophen before NSAIDs
    - aspiration if large effusion

  2. Refer to ortho
    - Young → reconstruction with graft
    - Older - PT to strengthen surrounding muscles to improve stability

  3. Inability to bear weight
  4. (+) deformity, swelling, ecchymosis
  5. Assess for compartment syndrome and NV injury

dx?
w/u?

A
  1. Tarsometatarsal Injury
  2. Wt bearing foot series, Often BL images for comparison; CT/MRI if clinical suspicion but nml x-rays
98
Q

mgmt for tarsometatarsal injury

A
  1. Non-displaced
    - Non-wt bearing splint/cast (short-leg posterior) x 6-8 wks
    - rigid arch support x 3 mo
  2. Displaced fracture/TMT joint
    - Splint as above
    - ORIF

nml angle measurement of MTP joint

what is Morton’s Neuroma?
MC where?

A
  1. A perineural fibrosis of common digital nerve as it passes between the metatarsal heads

dx?
w/u?
mgmt?

A
  1. Morton’s Neuroma
  2. XR (nml), MRI/US can detect neuroma but findings are inconsistent

  4. Risk factors: Obesity, flat feet, prolonged standing/jumping

dx?

A

Plantar Fasciitis

108
Q

presentation of plantar fasciitis?
w/u?

A
  1. Insidious onset
  2. Heel pain - worse when initiating walking
    - most severe during their 1st steps in AM (or after long period of inactivity/sitting)
    - lessens with walking
    - Worsens toward end of day d/t prolonged wt bearing
    - Relieved by sitting
  3. Tenderness directly over medial calcaneal tuberosity and 1-2 cm along the plantar fascia
  4. Passive dorsiflexion of toes may cause increased pain

XR to r/o other conditions

109
Q

mgmt of plantar fasciitis

A
  1. Non-surgical MC
    - Initial: OTC orthotic heel pad and home stretching program
    - Avoid barefoot walking & flat shoes, activities that may be causative (dancing, running)
    - Ice and NSAIDs
    - May take 6-12 mo to resolve
  2. Unresponsive
    - CSI into heel
    - Custom orthotic
    - Surgical: partial release of plantar fascia
