高校生アスリート腰椎椎間板ヘルニアに対しての経皮的内視鏡視下椎間板ヘルニア摘出術 （PED） の短期成績

Lumbar disc herniation is usually due to age related degeneration of annulus fibrosus, although sometimes lumbar disc herniation is caused by trauma, lifting injuries or sport activities. Percutaneous endoscopic lumbar discectomy （PED） is performed under local anesthesia and is only required ８-mm skin incision. The surgeon accesses the lateral lumber disc “so called transforaminal approach” using small camera and instruments that fit through the ７．５mm diameter cannula. PED is minimally invasive lumbar discectomy, especially for back muscle injury. Although PED is minimally invasive lumbar discectomy for athletes, it is unknown PED available for high school athletes.
The purpose of this study is evaluation of the results after PED for high school athletes. Four male and one female high school athletes with lumbar disc herniation were performed PED surgery under local anesthesia. Mean age is １６．５ years old. Time to return to play own sports and the incidents of recurrence of lumber disc herniation were investigated. Visual Analog Scale （VAS） for low back pain at the latest examination was measured.
All cases were able to perform the surgery under local anesthesia and return to own sports. Post operative course were successful. Time to return to their sport was from ４ to ８ weeks after surgery. The mean VAS （out of １０） for low back pain at latest examination was１．０.
PED for high school athletes is the minimal invasiveness and good short-term clinical results.
