The process of plantar fascia tissue change typically occurs as a consequence of
protracted mechanical overuse. Mechanical overuse may occur by excessive
stress, which would include increased body mass index (BMI), pathobiomechanics,
contact sensitization due to irresilient and uneven environmental surfaces and
excessive weight bearing activities. Such tissue changes are also prevalent in
certain instances associated with non-specific fasciitis syndromes.
Surgical treatment of plantar fasciitis or heel spur syndrome is indicated only
after conservative measures have failed. Conservative management includes
corticosteroid injections, orthotic therapy, orthopaedic taping and padding,
physical therapy, iontophoresis, stretching and/or flexibility programs, rest,
immobilisation (below knee casts), non-steroidal anti-inflammatory drugs, and
cessation of activity (Bordelon, 1993; Jacoby and Wolfe, 1991; Sammarco and
Helfrey, 1996; and Stone and Davies, 1996).According to Gill and Kiebzak (1996)
casting was the best conservative treatment method. Studies examined by Brekke
and Green (1998) and Bordelon (1993) observe approximately 90% of cases exhibit
total relief with conservative treatment alone
Acute rupture of the plantar fascia would require an extraordinary mechanical
event. Review of the podiatric literature indicates that this is a rarely
reported condition. Pai (1996) published a case report of a
degenerative/non-traumatic plantar fascia rupture which occurred and was
implicated with multiple cortisone injections for plantar fasciitis
This is the only non-traumatically caused case I could find in the podiatric
literature. Rolfe et. al (1997) reported two traumatic cases,
Christel et. al. (1993) reported 18 traumatic cases, 17 occurring in the
competitive athlete
and the largest series reported is 30 cases (Poux, D., Christel, P., Demarais,
Y., Parier, J., Roger, B., Viel, E. Les ruptures de láponevrose plantaire. J. Traumatol.
Sport 6:77-87, 1989 as discussed in Christel.) The definitive specialized
diagnostic study to evaluate for plantar fascia rupture is MR.
