We used Hartshill fixation system in 21 cases (12 males and 9 females). Mean age was 30.5years (range 7-81 yearş). Indications for surgery were vertebral fractures in 5, post laminectomy instability in 1, Pott's disease in 2, spinai tumor in 2, degenerative instability in 3, and spinal deformity in 8 cases.
Hartshill rectangies were used with sublaminar wires or pedicle screw bridges in 19 cases. İn two cases pedi-cle screwbridges were used with Harrington distraction rods.
Mean follow-up time was 5.5 months with a range of 3 to 11 months. Results are generally entirely satisfactory. İn trauma cases kyphosis angles were reduced from 14° to 3.6° scolioses were corrected from 60.2 degrees (35-100°) to 31.5 degrees (7-55°). Apical rotations were reduced from 35.8 degrees (17.2-52°) to 30.8 degrees (7.2-47°). Mean loss of correction in Cobb's angle was 3.1 degrees at the last follow-up. Complications related to im-plants were breakage of wires in two cases. There were no neurologic complications.
We think that Hartshill fixation system is easy and versatile that can be used in wide variety of spinai disorders.
