RESUMEN
OBJECTIVE: The aim of this study was to examine the effects of combining extracorporeal shock wave therapy or local corticosteroid injections with a conventional physical therapy (CPT) program for patients with shoulder impingement syndrome. DESIGN: This was a prospective single-blinded, randomized controlled study. METHODS: Sixty patients with unilateral shoulder impingement syndrome >3 mos were allocated to group A (a 4-wk program of CPT plus a single local corticosteroid injection of 40 mg triamcinolone acetonide mixed with 1% xylocaine, n = 20), group B (CPT only, n = 20), and group C (CPT plus extracorporeal shock wave therapy, 2000 impulses, 0.2-0.3 mJ/mm 2 , one session per week for 3 wks, n = 20). Subacromial space, shoulder pain and disability index, and shoulder range of motion were assessed at baseline and 4 and 12 wks posttreatment. RESULTS: There were no between-group differences at 4 wks. At the 12-wk follow-up, no significant differences were found between groups A and B. There was a significant difference in favor of group C compared with group A with the expectation of shoulder internal rotation and subacromial space. Group C was also superior to group B in all outcomes except for subacromial space. CONCLUSION: The addition of extracorporeal shock wave therapy to CPT induced more noticeable intermediate-term effects than CPT plus local corticosteroid injection or CPT alone.

A structural graft is often used to maintain correction and achieve union after anterior calcaneal lengthening osteotomy for treatment of flexible flatfoot. Autograft, the current gold standard, is limited in availability and configuration and is associated with donor site morbidity in as much as 48%, whereas the alternative allograft carries risks of disease transmission and collapse. Polyaryletherketone cage, with a healing rate similar to that of autograft, high stability, and no donor-site morbidity, has been used in spine surgery. However, its use has not been documented in foot and ankle surgery. We reviewed 15 patients with painful flatfeet after failure of conservative treatment who were treated by anterior calcaneal lengthening osteotomy using polyaryletherketone cage instead of bone graft. Minimum follow-up was 1 year (average, 1.27 years; range, 1-1.5 years). The male-female ratio was 1:1.5 (six males, nine females). Mean age at time of surgery was 10.8 ± 1.7 years (range, 8-13.5 years). Minimum follow-up was 1 year (average, 1.27 years; range, 1-1.5 years). Nine patients had a unilateral procedure and three had a simultaneous bilateral procedure, for a total of 15 operated feet (seven right and eight left). The paired t-test result was statistically significant in comparison of radiographic measurements at presurgery and postsurgery with P value <0.001. All cases showed full union clinically and radiographically at last follow-ups and no complications occurred. Our data suggest that polyaryletherketone cage may be used as a structural graft option for anterior calcaneal lengthening osteotomy.
