Common symptoms of failed back . 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. The indications for screw removal included the following: (1) pedicle screw fixation for thoracolumbar fracture without fusion and imaging confirmed solid fracture union, (2) patients required screw removal that presented persistent axial para-midline back pain to palpation or abnormal foreign body sensation due to pedicle fixation with imaging confirmed solid fusion, and no other cause found, e.g., infection. PubMedGoogle Scholar. Methods: Theater records from a single spinal surgeon's practice were reviewed to identify patients that had undergone lumbar fusion for discogenic back pain with subsequent pedicle screw instrumentation removal (Expedium, DePuy Synthes) in the preceding 3 years with a minimum of 18 months follow-up.

If after 6-12 months a patient continues to have or experience new pain, more imaging may be pursued. 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. The risk factors of screw loosening we found based on extraction torque were fixation in fractured vertebrae and non-fusion spine. However, nearly all cases resolve spontaneously within 2 years, thus identifying patients who require more detailed or invasive work-up is a challenging task for clinicians. The main symptom is usually pain, but many things can cause pain; the best way to know if a loose screw is actually the cause is to do x-rays, and then compare them with your older films.

While methods for spine surgery have significantly improved over the years, a patients recovery still depends on their own diligence and dedication, so following the Dos and Donts of spinal fusion recovery is a must. The presence of wear debris [23] was reported to induce osteolysis leading to screw loosening. f No significant difference of extraction torque was found among different screw diameter. Hence, further studies with larger sample size and stratified data according to different factors will be needed to better understand the prevalent of pedicle screw loosening. I am having the same problem with the screws coming loose. The mean torque of screws, which were diagnosed as loosening by X-ray, was 0.530.65Nm, which was significantly lower (p<0.0001) than others (1.650.98). b Lateral X-ray showed that the same screw was pulled out (white arrow). Revision pedicle screws. I pray for you and for all my brothers and sisters out there suffering. How do I know if my spinal fusion has failed? Anterior plate well applied. Spine J. 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).

Pedicle screws of non-fusion surgery placed in fractured vertebrae had significantly lower extraction torque and, therefore, could be vulnerable to loosening. Lee et al. L lumbar vertebrae, S sacrum, T thoracic vertebrae. The primary objective was to study the prevalent of pedicle screw loosening according to extraction torque during screw removal surgery and access the sensitivity and specificity of both X-ray and CT scan for diagnosing screw loosening. There was no linear correlation between extraction torque and patients height (p=0.848), weight (p=0.196), BMI (p=0.125), and time interval between the primary surgery and screw removal surgery (p=0.965).
