Plantaris tendon reconstruction of the lateral ankle ligaments.

Numerous procedures have evolved to operatively stabilize the ankle suffering from chronic inversion instability. The use of the plantaris tendon to anatomically reconstruct the lateral collateral ankle ligaments is among those that avoid the complication of restriction of subtalar joint range of motion. The authors present a modified technique of reconstructing the calcaneofibular and anterior talofibular ligaments using a plantaris tendon that maintains its insertion. A retrospective study of eight patients that elected the procedure for chronic ankle instability was conducted. The average follow-up was 12.7 months. Significant improvement in functional score (p less than 0.01) and talar tilt (p less than 0.05) was noted following the procedure. No restriction of subtalar joint motion was observed in any patient after the procedure. The advantages and disadvantages of the procedure are discussed. The authors conclude that the procedure appears to be a desirable alternative in achieving ankle stability while maintaining normal hindfoot function.

Fatigue perturbation of the os calcis.

This paper represents a philosophical shift in thinking. The authors propose that heel spur syndrome is not a primary soft tissue injury (i.e., enthesiopathy with concomitant bruising of the bursae and fat pad, and eventually the formation of a traction spur by the pull of the plantar fascia), but rather a primary bone injury. A microtrabecular stress failure (fatigue perturbation) of the os calcis occurs with secondary soft tissue involvement such as enthesiopathy, periostitis, myositis, bursitis, and finally the formation of a buttress callous (bone spur) to stabilize a microcortical crack. This study describes four stages in a progressive, sequential, pattern of fatigue failure of the os calcis. Clinical symptoms for each stage, along with supporting data such as x-rays, bone scans, and MRIs will be presented, as well as a suggested treatment plan for the chronic resistant cases.
