The current study examines 121 adults from a prehistoric hunter-gatherer population to aid in understanding bony spur etiology.
Calcaneal spurs are scored as present or absent on the dorsal or plantar side; they are analyzed in regards to their relationships with age, sex, osteoarthritis, cortical index, femoral head breadth and muscle markers.
Dorsal and plantar spurs frequencies increase with age (chi-squares = 16.90, 7.268, Ps < 0.05, respectively). Dorsal spurs were more frequent than plantar spurs (chi-square = 38.000; P < 0.0001). There is a positive relationship with calcaneal spurs and upper limb and lower limb osteoarthritis (chi-squares = 5.587, 7.640, Ps < 0.05, respectively).
The data presented support that dorsal spurs are in part the result of activities, but plantar spurs may be a more modern phenomena resulting from long periods of standing and excess weight.
