Foot Ankle Int. 2007 May ; 28(5): 575-80

BACKGROUND: Conservative treatment failure in symptomatic tarsal coalition usually mandates bar resection as a preferred operative alternative. The outcome of this procedure generally has been assessed by clinical measures. The purpose of our study was to evaluate whether plantar pressure distribution is normalized after bar resection.

METHODS: This study compared three groups: nine candidates for resection of tarsal coalition, nine patients between 2 and 4 years after bar resection (not the same patients who were candidates for resection), and nine control subjects. The ankle and hindfoot were evaluated according to the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale. Mean plantar pressure and mean normalized impulses were calculated during walking and running.

RESULTS: Significantly higher AOFAS scores were demonstrated in the postoperative group compared with the preoperative group (p<0.01). Medial midfoot pressures demonstrated the most consistent differences between groups. Preoperative feet had significantly higher medial midfoot pressures compared with the control group both during walking and running. Feet that had resection did not demonstrate significantly higher medial midfoot pressures during walking compared with the control group. However, during running, this segment’s pressures were significantly higher both in preoperative (p=0.000) and in postoperative (p=0.023) feet compared with the control group. Heel segments revealed decreased pressures laterally both in preoperative feet and in postoperative feet compared with the control group.

CONCLUSIONS: Running demonstrates that normal plantar pressures are not recreated after resection of tarsal coalition. However, close to normal walking pressure distribution is consistent with the favorable clinical outcome observed in most patients after bar resection.

CLINICAL RELEVANCE: Regaining full recreational activity after resection of a tarsal coalition, i.e. running, may have implications on abnormal foot loading and torque, thus promoting degenerative changes in the subtalar and adjacent joints.

Prince Georgians between ages 10 and 17 have two more days to register for one of nearly 500 remaining pairs of free athletic shoes as the Nike Summer Shoes program comes to a close.

The program, a joint effort by Nike and the National Recreation and Park Association, is giving away more than 2,500 pairs of shoes to Prince George’s County youth simply for registering using an online account.

Those interested can still sign up by going to set up a free SMARTlink account at any Maryland-National Capital Park and Planning Commission community center or other staffed recreation facility. A list can be found at www.pgparks.com.

Once an account is created, registration can be completed online and one of three pick-up locations, in College Park, Landover or Fort Washington, will be selected.

All that’s needed to claim the shoes is a printed receipt and participation in a Nike survey at the pick-up site, according to the commission.

The program began June 5. About 2,000 kids have registered and will claim their new shoes on Sunday. When signing up for the Nike giveaway, kids specified their gender and shoe size, but the type of shoes they receive will be left up to chance.

After the other competitors have gone off to take care of post-race aches and pains, a lone runner keeps going. Ironically, Lindsey Hollenshead was probably one of the first to cross the finish line, but dedication drives her to go the extra mile - literally.

Hollenshead, 18, is a distance runner for James Buchanan High School’s cross country and track and field teams. The 2007 JB graduate is not just an average runner either. She set a new JB cross country course record and school record this year and found success in postseason races. Not bad for someone who didn’t pick up the sport until the summer before her freshman year.

“I’ve just always had the desire to run,” Hollenshead said. “I just really enjoy doing it. I guess I’m built for it and not everyone is.”
