If you have had a lumbar fusion, then there is always the risk of a hardware malfunction, failure or breakage. However, in 24 patients who underwent multilevel (more than two segments) instrumentation, there was no significant difference regarding extraction torque (p=0.437) between screws placed in the end segments (n=88) and those in the mid segments (n=103), as shown in Fig. Loosening of the screws does not necessarily mean fusion will not eventually occur, or those symptoms are due to the loose screws.

But the reported data regarding screw loosening were traditionally based on radiological observation, which could be subjective and lead to a considerable variation. The limitation of radiological approaches led to a great variety of screw loosening rate in literatures. 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.

Types of hardware complications Privacy Severe scoliosis in adults, if left untreated, can also produce a number of associated complications such as lung impairment and cardiac issues. Some papers showed relatively low loosening rate, less than 1% in non-osteoporotic patients evaluated by X-ray [2, 5, 13], while other studies indicated a much higher rate of loosening [8, 12, 14, 15]. Nevertheless, like X-ray, the details about how the screw loosening was evaluated by CT scan were obscure and the assessment was subjective too. Why do screws come loose after spinal fusion? Fusion, hardware removal, fusion to fix failed fusion, etc. Later on, the screw was visible on xray pictures and my pain was just confirmation. 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.
