The cutoff values were 1.02 and 2.22Nm. During this first appointment, theyll ask about your symptoms, conduct a physical exam and have you perform some movements if you are able. In the last 6 years I've had 5 back surgeries. It reduces the range of motion of the stabilized spine, increases the fusion rate, and is generally considered to be safe with relatively low complication rate associated with the device [1, 2]. Getting an MRI Monday, then will find out what we can do. Google Scholar. Pedicle screw loosening is correlated to chronic subclinical deep Three slender patients complained of soft tissue irritation and a bothersome prominence because of the screws bulky profile. I do have a doctor appt next week, but previously was told my CT scan showed the fusion is solid. L5 S1 Fusion Surgery: Success Rate & Complications - CSC There is loosening of the T1 screws and residual instability (without static subluxation) at C7-T1. e Extraction torques of pedicle screw after fusion surgery (n=142) were significantly higher than those in non-fusion surgery. 6). Our results showed a low but significant linear correlation between extraction torque and BMD (p=0.010, R2=0.304, F=8.296) as well as age (p=0.045, R2=0.123, F=4.345), indicating pedicle screw in aged patients or those with low bone density may be less stable according to mechanical measurement, as shown in Figs.

This is done because the spine is unstable because of an injury, or because the spine needs to be fixed in place because of pain. Other factors that could cause bone loss or destruction, such as infection surrounding the implant, bone tumor, metabolic diseases, and microfracture due to excessive loading, are risk factors of pedicle screw loosening. Failed Spinal Fusion Surgery | Spine-health The screw, especially a larger diameter screw, is acting like a wedge so the board can actually be split apart around the screw. I have a plate, 6 screws, and artificial disk material between vertebra C5, C6, C7 1 year later, I returned to my orthopaedic surgeon because of cracking sounds. Brantley AG, Mayfield JK, Koeneman JB, Clark KR. This will allow them to visualize the hardware and the nearby structures to determine the extent of the damage. Now they are going to extend the rods up further, does that sound right. 11 4 Related questions Spinal nerve damage that can result in weakness, pain, loss of sensation, and loss of bowel or bladder control The vertebrae above and below the fusion are more likely to wear away, leading to more problems later Leakage of spinal fluid that may require more surgery Headaches Bleeding and blood clots Faraj AA, Webb JK. Thanks. There is a dramatic decline in screw numbers between 0.90 and 1.20Nm. Comparison of teriparatide and bisphosphonate treatment to reduce pedicle screw loosening after lumbar spinal fusion surgery in postmenopausal women with osteoporosis from a bone quality perspective. Symptoms The main symptom is pain following back surgery. . Pedicle screw loosening is a common complication after spine surgeries. Working from home offers plenty of benefits, but its not always an ideal experience. 165K views 4 years ago Dr. Gillard describes the case of a primary failed lumbar fusion, followed by a failed revision fusion. According to such criterion, the loosening rate was found to be 33%. Using X-ray radiographs taken the day before removal operations, radiolucent area (wider than 1mm) around the screw and/or the double halo were detected in 20 screws. The mean torque of the newly implanted screws was 2.730.75Nm (95% confidence interval 1.23 to 4.22). Now I know why! However, this indicator has seldom been used to study pedicle screw loosening after spine surgeries, especially regarding its relationship with radiological findings. Surgery in L5 S1 Fusion is denoted by its level. Normal spinal alignment preserved. 1997;6(5):3246. Ohtori et al. Jianting Chen or Hui Jiang. Revision pedicle screws. 3a. The longer it takes for the vertebra to fuse together . Sometimes unsuccessful surgeries are unavoidable, even when carried out by the most competent surgeons. If you have these symptoms, your surgeon may perform imaging tests to see problems in your hardware. The key factor regarding investigation of screw loosening is the assessment of whether a screw is loosened or not, which is traditionally based on radiological approaches [3]. I just had another MRI today and I now have more problems.

Heres what to eat and what to leave out of your pre-surgery diet. 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. The titanium alloy pedicle screws (Johnson&Johnson, USA; Medtronic, USA; Stryker, USA; Kanghui Med, China; FULE, China) with diameter of 4.0 to 6.5mm and length of 30 to 55mm were used in the primary surgeries. Surgery for removal of hardware is scheduled for August 26, wish it were sooner, but at least at this point there appears to be hope. Sanden [20] reported a 64% sensitivity of X-ray in 79 screws and a 35% rate of screw loosening, but their definition of a loosed screw was an extraction torque of 0.4Nm or less as there were no screws with and extraction torque between 0.4Nm and 0.75Nm. Meanwhile, by using extraction torque data, we analyzed the risk factors of screw loosening. How Much Better Will I Be After Lumbar Fusion? Spinal muscle injury. This result indicated that both radiological examinations were effective to confirm loosening screws; however, the low sensitivity implied a considerable number of loosening screws could be neglected by imaging study. I am still very conscious of the incision site and the feeling of the muscles and hardware in my back. Broken spinal hardware should be addressed right away. Our study reported a 33% loosening rate according to mechanical measurement of extraction torque during instrumentation removal surgery. Spine. I am sorry for what you are going through. , Screw backing out of metal plate on 4 cervical disks. Just recently My MRI shows that my fusion did not hold and I have a loose screw! An instrumented fusion can fail if there is not enough support to hold the spine while it is fusing.

Spinal tumors all affect the spine, but they can happen in different ways and cause different symptoms. In this process, two or more vertebrae are fused together and healed into one solid bone. I am having the same problem with the screws coming loose. Causes and Risk Factors Smoking Formation of scar tissue Recurring or persistent disc disease at adjacent levels Continued pressure from spinal stenosis Instability or abnormal movement The presence of wear debris [23] was reported to induce osteolysis leading to screw loosening.

As expected, extraction torques of pedicle screw after fusion surgery (n=142) were significantly higher than those in non-fusion surgery (n=84) (p=0.001), as shown in Fig. Heres how to tell if you can benefit from fusion surgery or if another approach might be a better choice. Therefore, a broken screw won't move very much in your spine, so if it's not causing you issues now (you don't have any pain, so it sounds like it isn't), the screw isn't likely to be a problem later on. Further study with larger simple size is needed to confirm the effect of screw length and diameter on extraction torque in the human spine. The mean extraction torque of removed screws was 1.551.00Nm; a torque force of less than 1.02Nm was used to define a screw as loosened.
