Abstract
|
|
|
Vertebral transpedicular screws provide secure attachment for posterior spinal fixation device the authors had experienced 29 cases of transpedicular screw fixation to obtain fixations of the thorcolumbar and lumbar spine instability. the
patients
were
operated between February. 1992 and May. 1995.
Spinal fusion was attempted at one to four levels of thoracic and lumbar spine. Follow-up period was from 6 to 33 months. averaging 16 months.
@ES The result was summerized as follows:
@EN 1) Of the 29 cases. 20 were spondylolisthesis and 9 were fracture and dislocaton. 10 patients (34.5%) were 30 years old. and 20 cases (69%) were female. Mean age was 42 years.
2) The symptom included low back pain. sciatica and intemittant claudificaton in the oder of incidence.
3) The sites of spondylolisthesis were L4-5 in 12 cases (60%) and L5-S1 in 8 cases (40%). The average degree of slippage in spondylolisthesis was Meyerding's grade l(85%) The sites of fracture were T12 in 5 cases (55.6%). L1 in 2 cases (22.2%).
L2
with
L3 in 1case (11.1%) and L1 in 1case (11.1%).
4) There was no patient with significant neurologic injury or functional root loss. A screw malposition was observed in one case.
5) The results of operations were considered exellent in 16 cases (56%) good in 10 cases (35%) and fair in 3 cases (10%). and satisfactory bony fusion was obtained.
