Imaging and surgical approach to a pediatric penetrating intradural wooden splinter: case report.

Penetrating spinal injuries by wood are infrequently reported. They are particularly rare in children. Only 6 cases of wooden fragments causing penetrating intradural spinal injury have been reported. The authors report a case of a 3-year-old girl who suffered a penetrating wound on her lower back after sliding on a wood floor. A portion of the extraspinal part of the wooden splinter was removed prior to presentation; however, a high suspicion for retained foreign body was maintained. Findings on CT were equivocal, but the diagnosis was confirmed on MRI. An incomplete cauda equina syndrome was noted on examination. She was taken to the operating room for removal of the wooden foreign body, repair of a durotomy, and repair of a CSF leak. At 8 months after surgery, the patient had fully recovered without sequelae. The roles of imaging modalities, prophylactic antibiotics, and surgery are discussed.
