Bunions - Hallux Valgus
Bunions - Hallux Valgus
Not so much good luck But you can cross them
Bunions - Hallux Valgus
  • NOT likely from high heel shoes (Myth)
  • High heels may exacerbate the underlying etiology.

Hallux Valgus
  • Affects 1 of adults in the US. (National Health
    Interview survey by the National Center for
    Health Statistics)
  • Incidence increased with age
  • 3 15-30 years
  • 9 31-60 years
  • 16 gt 60 years
  • Female to Male ratio - 21 to 41
  • The role of genetic predisposition has also been
    noted, with evidence to suggest familial
  • Gould et al., 1980 1

Hallux Valgus - Etiology
  • Biomechanical instability
  • Most common
  • Difficult to understand and evaluate
  • Genetically inherited and/or from underlying

Hallux Valgus - Etiology
  • Arthritic/metabolic conditions
  • Gouty arthritis
  • Rheumatoid arthritis
  • Psoriatic arthritis
  • Connective tissue disorders such as Ehlers-Danlos
    syndrome, Marfan syndrome, Down syndrome, and
    ligamentous laxity

Hallux Valgus - Etiology
  • Neuromuscular disease
  • Multiple sclerosis
  • Charcot-Marie-Tooth disease
  • Cerebral palsy
  • Traumatic compromise
  • Structural deformity i.e. Abnormal metatarsal

Bunions - Hallux Valgus
Bunions - Pathophysiology
  • Hallux and digits generally remain parallel to
    the long axis of the foot.
  • Medial tension causes the medial collateral
    ligaments to pull on the dorsomedial aspect of
    the first metatarsal head, causing the bone to
  • Lateral tension causes the sesamoid apparatus to
    fixate in a laterally dislocated position.
  • Remodeling (bone and cartilage) occurs laterally
    and medially.
  • Without correction of the biomechanical etiology,
    excessive pronation continues, with propagation
    of the deformity.

  • Hallux position
  • Medial prominence
  • First metatarsophalangeal joint ROM
  • First ray ROM
  • Plantar keratosis
  • Pain location
  • Contracture of the extensor hallucis longus
  • Associated deformities

Evaluation Labs and XRay
  • Uric acid, ESR, CRP, ANA, RF
  • Foot AP, Lat, and Oblique

  • Stage 1 - excessive pronation causes
    hypermobility of the first ray, causing the
    tibial sesamoid ligament to be stretched and the
    fibular sesamoid ligament to contract, and
    lateral subluxation of the proximal phalanx
  • Stage 2 - hallux abduction progresses, with the
    flexor hallucis longus and flexor hallucis brevis
    gaining lateral mechanical advantage.
  • Stage 3 - further subluxation occurs at the first
    metatarsophalangeal joint, with formation of
    metatarsus primus adductus.
  • Stage 4 - the first metatarsophalangeal joint
    finally dislocates.

Hallux Valgus - Treatment
  • Medical therapy
  • Adapting footwear
  • Pharmacologic or physical therapy
  • Functional orthotic therapy
  • Activity
  • Weight
  • Top cover
  • Biomechanical examination
  • Modifications - cushions
  • Surgical therapy

Look good and feels good.
  • Six months to full activity
  • Best to take 2 weeks off and elevate leg
  • Ice popliteal fossa for 1 week postoperatively to
    reduce swelling
  • Ambulating in 2 weeks
  • Pain free without strenuous exercise at 3-5 weeks

Heel Pain
Plantar Fasciitis
  • In US5
  • 10 of runner-related injuries
  • 11-15 of all foot symptoms requiring
    professional care
  • 10 - general population
  • Presents bilaterally 1/3 cases
  • Race and ethnicity play no role in the incidence
  • Peak incidence may occur in women aged 40-60

Plantar Fasciitis
  • A thickened fibrous aponeurosis
  • Originates from medial tubercle of the calcaneus
  • Runs forward to insert into the deep short
    transverse ligaments of the metatarsal heads
  • Continues forward to form the fibrous flexor
    sheathes on the plantar aspect of the toes
  • Central plantar fascia is the thickest and
    strongest section, and most likely to be involved
    with plantar fasciitis.
  • Function - provide static support for the
    longitudinal arch of the foot and to assist with
    shock absorption during foot strike (2-3 times an
    individual's body weight with each step).

Plantar Fasciitis - Pathophysiology
  • Increased risk
  • pes planus (low arches or flat feet)
  • pes cavus (high arches)
  • Pain - collagen degeneration associated with
    repetitive microtears of the plantar fascia.
  • Common h/o increase in weight-bearing activities
    causing the microtears exceeding healing
  • Elderly biomechanical (functional and
    degenerative factors)

Plantar Fasciitis - Etiology
  • Extrinsic risk factors
  • Training errors
  • Overuse Most common
  • Equipment
  • Intrinsic risk factors
  • Structural risk factors
  • Overpronation, discrepancy in leg length,
    excessive lateral tibial torsion and excessive
    femoral anteversion
  • Functional risk factors
  • Tightness or weakness of soleus, gastrocnemius,
    Achilles tendon and intrinsic foot muscles.
  • Degenerative risk factors
  • Poor intrinsic muscle strength and poor force
    attenuation secondary to acquired flat feet and
    compounded by a decrease in the body's healing

Plantar Fasciitis - Symptoms
  • Intense sharp heel pain with the first couple of
    steps in the morning.
  • Pain is anterior aspect of the calcaneus, but may
    radiate proximally in more severe cases.
  • Dull ache in the heel at the end of the day,
    especially after extensive walking or standing.

Plantar Fasciitis - Physical Exam
  • Point of maximal tenderness at the anteromedial
    region of the calcaneus.
  • Pain along the proximal plantar fascia.

Plantar Fasciitis - Physical Exam
  • "windlass" test - Passive dorsiflexion of the
    toes which elicits Sx pain
  • Having the patient bear weight during the
    windlass test increased the sensitivity of the
    test from 13.6 to 31.8 (De Garceau, 2003) 9

Plantar Fasciitis - Treatment
  • Correcting training errors by
  • relative rest
  • ice after activities
  • evaluation of the patient's shoes and activities
  • Correction of biomechanical factors by
  • stretching and strengthening program (PT)
  • Then, consider night splints and orthotics
  • Finally, other treatment options are considered.
  • NSAIDs are considered throughout the treatment
    course for pain control.
  • Time for resolution - often 6 to 18 months.

Plantar Fasciitis - Treatment
  • Iontophoresis Electric stimulation
  • Use of electric impulses from a low-voltage
    galvanic current stimulation unit to drive
    topical corticosteroids into soft tissue
  • Corticosteroid Injections
  • Greatest benefit if administered early
  • Studies7,8 have found steroid treatments
    successful 70 or better
  • Potential risks
  • rupture of the plantar fascia
  • fat pad atrophy.
  • Autologous blood injections
  • Ignites the healing process
  • Surgery
  • Success rate of surgical release is 70 to 90
  • Potential risks
  • flattening of the longitudinal arch
  • heel hypoesthesia.

Ankle Sprain
  • Common site for acute musculoskeletal injuries.
  • Sprains 75 of ankle injuries
  • Acute ankle trauma 10 to 30 of sports-related
    injuries in young athletes
  • Estimated 1 million persons present with acute
    ankle injuries
  • gt40 ankle sprains have potential to cause
    chronic problems

Ankle Sprain
Ankle Sprain
Ankle Sprain
  • Anterior drawer test - assess the integrity of
    the anterior talofibular ligament
  • Inversion stress test - assess the integrity of
    the calcaneofibular ligament

Ankle Sprain
  • Grade I partial tear of a ligament
  • Mild tenderness and swelling
  • Slight or no functional loss (i.e., patient is
    able to bear weight and ambulate with minimal
  • No mechanical instability (negative clinical
    stress examination)
  • Grade II incomplete tear of a ligament, with
    moderate functional impairment
  • Moderate pain and swelling
  • Mild to moderate ecchymosis

    has pain with weight-bearing and ambulation)
  • Mild to moderate instability (mild unilateral
    positivity of clinical stress examination)
  • Grade III complete tear and loss of integrity of
    a ligament
  • Severe swelling (more than 4 cm about the fibula)
  • Severe ecchymosis
  • Loss of function and motion (i.e., patient is
    unable to bear weight or ambulate)
  • Mechanical instability (moderate to severe
    positivity of clinical stress examination)

Ankle Sprain
  • Grades I or II sprains
  • Accurate early diagnosis
  • RICE (rest, ice, compression and elevation)
  • Maintenance of ROM - Functional Rehabilitation
  • Ankle support
  • Grade III
  • Early motion and mobility are recommended
  • Ligamentous strength returns months after injury
    delayed functional rehab

Ingrown toenails
  • Etiology4
  • Inheritance - genetically predisposed inwardly
    curved nails with distortion of one or both nail
  • Underlying bony pathology causing deformation of
    the nail
