We report a case with dumbbell tumor of the lumbar spine who recived recapping laminoplasty by the T-saw pediculotomy method.
The patient was a 52-year-old woman who complained of slight lumbago and abdorminal pain. MRI showed a dumbbell tumor at the L3 level. She was threrfore admitted to our hospital for examination and treatment.
We planned recapping laminoplasty by T-saw pedinoplasty by T-saw pediculotomy, but the tumor by only posterior approach was considered diffecult. However, as this operative method yields a wide view of the intervertebral foramen, then we were able to perform total resection of the tumor by the posterior approach.
Recapping laminoplasty by T-saw pediculotomy not only yields an excellent and wide surgical field, but also achieves physiologecal and anatomical elements after excision of the tumor.
