The reasons that no significant different extraction torque was found among screws with different length and diameter might be due to the relatively small sample size and narrow range of length (3055mm) and diameter (4.06.5mm).

In both cases, bilateral S1 pedicle screws were inserted outwardly using a free-hand technique, and on one side, screws induced severe pain by impinging on an L5 root. 1993;18(15):22318 discussion 2238-2239. 1 Can screws come loose after spinal fusion?

The main role of the screw in lumbar fusion is to reduce the motion of the spine and to conduct the stabilization, whereas screw loosening is observed in quite a few literature works (7)(8)(9). The same X-ray and CT scan were scheduled before screw removal surgery to evaluate fracture union and spine fusion, as well as stability of instrumentation. During the follow-up period, 97 patients had presented with CT signs of pedicle screws loosening (1-mm radiolucent zone around at least 1 screw and double halo sign); however, out of those only 39 complained of axial pain with ODI values over 40; those patients underwent revision surgery. Furthermore, the sensitivity and specificity of the X-ray criteria of loosening could be confounded by many factors, such as metal image artifact, intestinal gas, and display angle. You can tell if the screws attached are loose when a sudden pain is experienced or when you feel bulges in your spine. Loosening of instrumentation frequently occurs when the bones of the spine dont heal or fuse correctly; this poor healing my also cause hardware to shift or break.

Both X-ray and CT had high specificity to detect screw loosening, but their sensitivities could be overestimated. Scatter diagram of patients average torques and BMD. The relatively low related coefficients might be due to the existence of numerous confounding factors, and these results indicated that the failure risk of instrumentation increased with age and osteopenia/osteoporosis, which was widely credited but rarely proven in vivo with mechanical measurement.
