Podiatry Landmarks Exam Questions
& Answers (Grade A+)
Sheehan in Diabetes Care in 2003 -
correct answer ✅"If patients did not heal 53% of wound by 4
weeks they did not end up healing their wound"
The midpoint between the percentage area reduction from
baseline at 4 weeks in patients healed versus those not healed at
12 weeks was found to be 53%. Subjects with a reduction in ulcer
area greater than the 4-week median had a 12-week healing rate of
58%, whereas those with reduction in ulcer area less than the 4-
week median had a healing rate of only 9%.
Miller in 2017 in FAI -
correct answer ✅"ORIF of posterior mal restored 97% of
syndesmosis stability"
Following ORIF of posterior mal, the syndesmosis stability was
restored over 97%.
Supports Gardner et al (2006 Clinic Orthop Rela Res) study that
showed that reducing and fixing posterior mal restores tension to
PiTFL
Grayson Et Al in JAMA in 1995 -
correct answer ✅"Probe to bone has a 89% positive predictive
value for OM."
56% negative predictive value. 68% sensitivity and 85% specificity

Lavery et al in Diabetes Care 2007 -
correct answer ✅"Probe to bone has a 98% negative predictive
value"
Probe to bone has 57% positive predictive value. 98% negative
predictive value. 87% sens and 91% specific
Reilly and Kaleta in JAPMA in 2001 -
correct answer ✅"ESR of 70 had a 100% positive predictive value
for OM"
70mm/hr = ESR cut off for OM. 100% predictive value and 83%
negative predictive value. 89.5% sens and 100% spec.
Fleischer in JFAS in 2009 -
correct answer ✅"Ulcer depth of >3mm and CRP > 3.2 you should
suspect OM instead of cellulitis"
Most informative clinical and lab test for differentiating OM from
cellulits is ulcer depth > 3mm and CRP > 3.2 mg/dl
Armstrong et al in JBJS in 1999 TAL -
correct answer ✅"TAL leads to reduction of plantar forefoot
pressures by 25 percent"
, Podiatry Landmarks Exam Questions
& Answers (Grade A+)
The mean peak pressure on plantar forefoot went from 86 ± 9.4
newtons per square centimeter
preoperatively to 63 ± 13.2 newtons per square centimeter at eight
weeks s/p Tendoachilles lengthening
Armstrong Et al in JFAS 1997 Amps -
correct answer ✅"60% of hallux amputations lead to a second
amputation"
After Hallux amputation, 60% = second amputation,
21% = third amputation
●7% fourth amputation
●15% percent of the patients who had a second amputation had it
contralaterally
●17% BKA below-knee amputation and 11% had a Transmetatarsal
amputation on the same extremity
●Mean time from the first to the second amputation was
approximately 10 months
Ramsey and Hamilton in JBJS in 1976 -
correct answer ✅"1mm in lateral displacement of talus leads to
42% decrease in tibiotalar contact area."
