Of the several known spine surgery problems, the most accepted and most widely used method for repair is pedicle screw fixation1,2,3,4,5,6,7,8,9,10,11). After fixation, the most common reasons for revision surgery7) are implant problems and pseudoarthrosis. Implant failure3,4) has been reported at rates of 3-12%. Methods and instruments to remove broken screws have been described in the literature5,12). However, no additional methods6,10), other than the rod techniques for removing normal screws, have been described. In the U-rod technique described by Kse et al.6), the cap screws are removed with an Allen key, and the screw is placed in the U-shaped rod after removing the rods. After tightening the screw head, the screw with a mobile head becomes a monoblock screw. This single-structure screw can be removed by hand or with pincers. All of these procedures result in extra effort, leading to loss of time. Cutting rods in good condition is a loss of material. In addition, large metal cutters are required to cut the rods, a rod bender is needed to shape, and pincers are needed to turn the rod placed on the screw head. Our screw remover design is a single piece and will not damage surrounding tissue or the pedicle (Fig. 1A, B). There is no need for metal cutters or a rod bender; thus, reducing the time and effort required. The tool also removes the need to clean the fibrous tissue covering the internal screws to determine screw shape. Thus, bleeding associated with debridement of fibrous tissue is prevented.

An 18-year-old male presented after a motor vehicle rollover accident. Computed tomography (CT) scan confirmed the diagnosis of Type II odontoid fracture. Considering the patient's young age and the limitations of C1-C2 fusion including significant loss of cervical rotation, temporary internal fixation with a lateral mass fixation of C1 and pedicle fixation of C2 without fusion was done. CT scan done at 6-month follow-up visit showed healed odontoid fracture and excellent C1-C2 alignment. At ninth postoperative month, internal fixation was removed. Patient had normal movements of cervical spine at 1-year follow-up. Temporary internal fixation can be an important tool in the armamentarium of the surgeon in treating type II odontoid fractures in young adults and children. This strategy avoids the complications halo fixation and immobilizes the unstable C1-C2 segment without fusion. Removal of the internal fixation after healing allows restoration of the rotational motion.
