The popping may just be the soft tissue becoming accustomed to its new position post surgery. This picture shows metal artifact around screw tail in CT scan, which may confuse the interpretation of screw loosening. Pedicle screws in aged patients or patients with lower BMD might be less stable due to lower extraction torque. Spinal fusion is a time-tested surgical approach to many types of chronic spine-related pain, especially in the neck and lower back. Some reports showed that increasing length and diameter could increase the stability of pedicle screw [24, 25], which had not been observed from our results. There was no significant difference regarding the diameter or length of screws as shown in Fig. 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.

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). Meanwhile, stress shielding can lead to a decrease of stress transferred through the bone tissue, which can reduce bone mineral density and remodel the bone surrounding the screw. Anterior plate well applied. Spinal tumors all affect the spine, but they can happen in different ways and cause different symptoms. Symptoms Of Loose Screws After Spinal Fusion The most common type of pedicle screw used in spinal surgeries is known to loosen or break over time. In general, we found a 33% pedicle screw showed an extraction torque less than 1.02Nm, which might be considered to be loosening according to our data distribution. What are the signs that a surgical screw is coming loose? The screws at the ends of implant were supposed to share more strain and be vulnerable to loosening [3]. In a small percentage of men who have an anterior fusion, an infrequent complication results in difficulties with ejaculation following spine fusion surgery.
