CONSIDERATION OF SPORT DEMANDS FOR AN 18-YEAR-OLD LACROSSE PLAYER WITH RECALCITRANT SYMPTOMATIC SPONDYLOLYSIS: A CASE REPORT.

background and purposeSpondylolysis is an anatomical defect or fracture of the pars interarticularis and encompasses almost half of all cases of low back pain in adolescent athletes. Most athletes return to sport with conservative treatment, but it is possible that consideration of sport demands may further improve rate of successful return. When surgery is performed, complication rate is high, so all conservative measures should be explored before considering surgical intervention. The purpose of this case report is to present a program where demands of sport were considered and allowed successful return to sport for a subject with recalcitrant symptomatic spondylolysis that had failed to respond to prior treatment. CASE DESCRIPTION: An 18-year-old lacrosse player with a history of recalcitrant symptomatic spondylolysis that failed three courses of conservative treatment and had been unsuccessful in returning to sport. A multi-phase program with a focus on multi-planar and full kinetic chain activities that addressed the nature of the sport demands is described, along with improvements in pain level, strength, range of motion, and subjective outcome scores. OUTCOMES: The subject was able to successfully return to sport after 10 weeks of physical therapy and complete the remaining few months of his lacrosse season without reinjury. Range of motion and strength testing was markedly improved upon discharge. The subject's Modified Oswestry Disability Index improved from 16% to 0% and his pain level did not rise above 2/10 with any sport activity upon return. DISCUSSION/

conclusionsAlthough return to sport rates following spondylolysis in young athletes is high, this case report demonstrates that a consideration of sport demands may increase return to sport rates in athletes that do not respond to standard care and prevent surgical intervention. LEVEL OF EVIDENCE: Level 4, single case report.
