Progressive loss of correction may make revision surgery difficult and complicated; therefore, it is important to ascertain whether correction loss has occurred at the RF site. Statistical analysis: Yamato. Recovery from spinal fusion surgery takes longer than with other types of spinal surgery. To assess the long-term prevalence of vertebral fractures after lumbar spinal fusion with instrumentation. Acute vertebral fractures were determined in 20 vertebrae in 14 (24%) of the 59 female patients, whereas 1 male patient (2%) had 1 vertebral fracture during the follow-up period. You can gradually begin to resume your activities until you are back to full function and movement. In our continuous pain group, revision surgery was performed in 22 of 23 cases at the final follow-up. Received 2018 Jan 9; Revised 2018 Mar 23; Accepted 2018 Mar 23. C and D: Twenty-four months later, an RF was incidentally found on radiographs. Of the patients in this study who initially elected nonoperative care, conversion to revision surgery was ultimately seen in 33.3% (9/27) because pain and discomfort progressed. Surgery can relieve pressure on the nerves, stabilize the vertebrae and restore your spines strength. National Library of Medicine Data were retrospectively collected from a single-center prospectively maintained database of ASD operations. It has also been reported that a nonideal correction can lead to sagittal imbalance and increased mechanical stress on the posterior implant after PSO. 8600 Rockville Pike : Risk factors for major peri-operative complications in adult spinal deformity surgery: a multi-center review of 953 consecutive patients. Occipitocervical fusion (OCF) is an effective surgical treatment for trauma, inflammation, tumor, and congenital diseases of the spine, and also iatrogenic factors leading to occipitocervical instability. In contrast, some authors have performed revision surgery in all RF patients regardless of the presence of symptoms.1,11 In the current study, nonoperative care was provided in 33.3% (18/54) of cases at the last follow-up, with no additional symptoms and little change in alignment in 17 of the 18 cases. It occurs when one of your vertebrae, the bones of your spine, slips out of place onto the vertebra below it. Our study revealed that the clinical symptoms at the time of RFs were pain in 42 (77.8%) of 54 cases, neural symptoms in 1 case (1.9%), and no onset of new symptoms in 11 cases (20.4%). The objectives of this study were to investigate the time course of clinical symptoms and treatment progress in patients with RFs following ASD surgery and to establish treatment recommendations. The link was not copied. Spinal fractures can be stable or unstable.

The same authors17 also reported development of an RF in 9.0% of an entire ASD patient population at a mean of 14.7 months and in 22.0% of patients who underwent pedicle subtraction osteotomy during a minimum 1-year follow-up. Spine (Phila Pa 1976) 35:219226, 2010, Schwab FJ, Hawkinson N, Lafage V, Smith JS, Hart R, Mundis G, et al. Bisphosphonates and parathyroid hormone analogs for improving bone quality in spinal fusion: State of evidence. At her first outpatient visit, plain cervical radiographs showed the following in the sagittal plane: a 9.5-mm distance from the odontoid tip to Chamberlain line and an atlas-dens interval (ADI) of 7mm (Fig. 8600 Rockville Pike Loss of correction and alignment deterioration were an indicator that revision surgery was necessary. A compression fracture is a type of broken bone that can cause your vertebrae to collapse, making them shorter. Furthermore, we hypothesized that a nonideal occipitalcervical angle, a key factor in implant failure, could lead to occipitocervical imbalance and thus concentrate stress at in the region of the craniofacial junction. In older adults, wear and tear on the spine and disks (the cushions between vertebrae) can cause this condition. Diagnosing Failed Back Surgery Syndrome | NYU Langone Health Nonoperative care was initially provided in 27 cases. There is various hardware involved in the surgery that must be acknowledged to understand the benefits the procedure provides. In single regression analysis, the predictor variables were the extents of change in the LL, PT, SS, PI-LL, local angle, and RF periods (p < 0.05). Cervical 3-dimensional (3D) computed tomography (CT) reconstruction indicated an atlanto-occipital malformation and C2-3 fusion, leading to difficulty in locating the tangent of the inferior aspect of C2. Only the parameter C7-CSVL was significantly improved at the final follow-up compared with RF development (p = 0.032). You might have some pain and discomfort following spinal fusion surgery. Medications can help manage this pain for many people. The most severe pain will be in the days immediately following surgery. It will fade as you continue to recover. Your doctor will prescribe pain medication to help manage the pain in the first week or two. Eur Spine J 23 (Suppl 6):610615, 2014, Luca A, Ottardi C, Sasso M, Prosdocimo L, Luca A: Instrumentation failure following pedicle subtraction osteotomy: the role of rod material, diameter, and multi-rod constructs. 2023 Feb;15(2):448-459. doi: 10.1111/os.13609. Patients with RFs were classified as being asymptomatic in 11 cases (including the second RF in the patient with 2 RF cases), having temporary pain in 19 cases, having continuous pain in 23 cases (including the first RF in the patient with 2 RF cases), and having neural symptoms in 1 case. Spinal fusion consists of fixing two bone pieces together with the use of screws, plates and titanium bars. [46] However, rod breakage is a common complication after spinal fusion surgery. ASD was defined as the presence of at least one of the following indicators: degenerative or idiopathic scoliosis, deformity with posttraumatic fractures or iatrogenic deformity with spinal curvature greater than 20 in the coronal plane, sagittal vertical axis (SVA) greater than 50 mm, pelvic tilt (PT) greater than 25, and/or thoracic kyphosis (TK) greater than 60. Spine (Phila Pa 1976). 2019 Dec 20;14(12):e0226848. If symptoms occur, they may include pain, clicking joints, and reduced mobility. Nonsurgical treatments cannot undo the crack or slippage, but they can provide long-term pain relief. For a fusion surgery, your surgeon fuses (connects) the two affected vertebrae. Minimal access versus open transforaminal lumbar interbody fusion: meta-analysis of fusion rates. The overall length of the surgery depends on how easily the surgeon can access the spine, and if any other procedures are being performed. Spinal fusion is carried out to treat degenerative diseases of the spine, such as: In some cases, spinal fusion carried out as part of a wider surgical procedure to repair the spinal cord, such as when treating a slipped disc. The https:// ensures that you are connecting to the Wen Z, Mo X, Ma H, Li H, Liao C, Fu D, Cheung WH, Qi Z, Zhao S, Chen B. Orthop Surg. This analysis of 54 RFs in 53 patients following corrective fusion surgery for ASD demonstrates a relationship between symptoms and alignment change. Unilateral versus bilateral pedicle screw fixation in lumbar fusion: A systematic review of overlapping meta-analyses. Naturally, there are some risks associated with the surgery. Patients who underwent surgeries for cervical deformity or traumatic fracture in the acute phase were excluded. The optimum therapy for patients with diminished pain is a matter of debate; in 3 of 10 cases in the present series, treatment was converted to revision surgery. The number of rods in the primary ASD surgery was 2 in 46 cases, 3 in 7 cases, and 4 in 1 case. Less common types of spondylolisthesis include: Spondylolisthesis and spondylolysis occur in about 4% to 6% of the adult population. Smith et al.16 reported that pain was the primary symptom in 97% (29 of 30) of patients, with symptomatic RF and postoperative loss of deformity correction noted in 17%. Restrictions Takeaway Spinal fusion surgery connects two or more vertebrae of your spine together. : Prospective multicenter assessment of risk factors for rod fracture following surgery for adult spinal deformity. In the asymptomatic group, none of the patients required revision surgery. Neurosurgery 71:862867, 2012, Smith JS, Shaffrey E, Klineberg E, Shaffrey CI, Lafage V, Schwab FJ, et al. There were no significant differences in age, sex, and interval from ASD surgery to RF among patients who were asymptomatic, had temporary pain, or had continuous pain. Accessibility In such cases, spinal alignment in the standing position was maintained after RF. While the condition wont go away on its own, you can often experience relief through rest, medication and physical therapy. 2020 Aug 18;12(2):8590. doi: 10.4081/or.2020.8590. Data obtained in 304 consecutively treated ASD patients (mean age 62.9 years) were reviewed (Table 1). A vertebra slips out of place onto the vertebra below. Back The primary symptoms and the time course of symptoms and treatment were carefully investigated by reviewing patient medical records. If, however, the broken screw was pressing on a nerve or obstructing the spinal canal, surgery to remove the instrumentation would be considered. Fracture The. Heilbronner AK, Dash A, Straight BE, Snyder LJ, Ganesan S, Adu KB, Jae A, Clare S, Billings E, Kim HJ, Cunningham M, Lebl DR, Donnelly E, Stein EM. Poor bone graft fusion in the area of the occipitocervical junction and instability in the lower cervical region became evident at the postsurgical follow-up. Whole-spine radiographs obtained at a minimum of 1 year after surgery were available for 300 patients (follow-up rate 98.7%). There was no difference between the 2 groups before RF development. government site. Lets take a look. In addition, the OC2A and POCA were corrected to 9.5 and 117.8 degrees, respectively. Advertisement During the three to six months following spinal fusion surgery, the lumbar fusion bone mass starts becoming established. Critically revising the article: Kobayashi, Banno, Oe, Mihara, Matsuyama. Smith et al.16 reported that 87% of symptomatic RF patients had undergone revision surgery at the last follow-up and the remaining patients had experienced an improvement in symptoms with nonoperative treatments and thus declined revision surgery. RFs were defined as breakage of the rod identified using radiographs regardless of the presence or absence of symptoms, which included fractures incidentally detected on routine examination of radiographic images. There were 54 RFs in 53 patients (43 females, 10 males; mean age 68.5 years [range 4184 years]) occurring at a mean of 21 months (range 647 months) after surgery. A vertebra slips out of place onto the vertebra below. An additional inclusion criterion was the need for whole-spine radiographs obtained at a minimum of 1 year after primary surgery. [1015] In long-term follow-up, the loss of lower cervical lordosis and acceleration of degeneration, even the failure of implants, have been suggested. As there is not enough research conducted to formulate a textbook definition of what the effects might be in the long run, it becomes important to know what they could be. This can give more stability to the entire spine. MeSH If there is an increase in pain post spinal fusion surgery, then be careful and view this pain as a warning sign from your body to slow down your activity. Bone. Tensile forces through the posterior graft cause bone resorption and reduce the chance of obtaining solid fusion.[24]. [1,8,12] At present, many reports indicate that improper OC2A angles in occipitocervical fixation and fusion can affect clinical efficacy and accelerate degeneration of the lower cervical spine. Symptoms may include chronic pain in the back, neck, or legs, which can be dull or sharp, aching, burning, or radiating. EH: Radiographs obtained before RF (E), at diagnosis of RF (F), 1 year after RF (G), and 3 years after RF (H). Our analysis of 54 RFs in 53 patients following corrective fusion surgery for ASD showed the relationship between symptom and alignment change. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Cervical spinal fusion can be indicated to treat these pathologies. Despite the significant incidence of rod fractures (RFs) following long-segment corrective fusion surgery, little is known about the optimal treatment strategy. official website and that any information you provide is encrypted The incidence of the adjacent and the nonadjacent, remote level subsequent vertebral fractures after lumbar spinal fusion is not well described in the literature. Screws are used in lumbar fusion to stabilize the spine. The same forces that can cause the hardware to break can also cause the screws to become loose. This, in turn, can create spinal instability and pain. Collectively about 1 in 10 patients who have a low back fusion will need a second surgery to fix non-union or hardware failure (8). sharing sensitive information, make sure youre on a federal Included in this study were consecutive ASD patients aged 18 years or older, treated between May 2010 and December 2015, in whom corrective fusion surgery involved a minimum of 3 levels of fusion. You may need surgery if you have high-grade spondylolisthesis, the pain is severe or youve tried nonsurgical treatments without success. The surgery is done to help stabilize your spine, reduce pain, or This study was approved by the institutional review board of the Hamamatsu University School of Medicine. Bethesda, MD 20894, Web Policies RFs initially occurred in a unilateral rod in 38 cases and bilateral rods in 16 cases. Boldface type indicates statistical significance. Spine (Phila Pa 1976) 37:489500, 2012, DeWald CJ, Stanley T: Instrumentation-related complications of multilevel fusions for adult spinal deformity patients over age 65: surgical considerations and treatment options in patients with poor bone quality. Spinal cord injuries can cause one or more of the following signs and symptoms: Loss of movement; Loss of or altered sensation, including the ability to feel The lower instrumented vertebra was the ilium in all patients. Spinal cord monitoring was performed during surgery. No special preparation for discectomy is required. Rod breakage after occipitocervical fusion for BI and AAD. Togawa and Oe work at a donation-endowed laboratory in the Division of Geriatric Musculoskeletal Health. Fusion procedures increased 70% between the. Supervision: Guang Zhou Li, De Jun Zhong. The authors report no conflicts of interest. Togawa and Oe work at a donation-endowed laboratory in the Division of Geriatric Musculoskeletal Health. During surgery, we discovered a rod breakage in the region of the occipitocervical junction, atlanto-occipital joint instability, and failure of the initial fusion. When the screws get loose, it can also result in infections. It may put pressure on a nerve, which could cause lower back pain or leg pain. smaller than for the lumbar spine. In the study reported by Smith et al.,17 pseudoarthrodesis was confirmed intraoperatively in all patients who underwent revision surgery. Its possible to live with spondylolisthesis for years and not know it, since you may not have symptoms. In the remaining 11 cases there was no onset of new symptoms, and RFs were incidentally diagnosed on radiographs at a follow-up visit. In the present study no signs of mobility at the RF site were observed in 8 of 29 patients undergoing revision surgery. We defined osseous nonunion as obvious mobility at the RF site. In their study, Smith et al[7] found a global incidence of symptomatic rod breakage of 6.8% in adult patients who underwent corrective surgery for spinal deformities. A cantilever technique was used during rod installation. The clinical symptoms at the time of RF were additional back, low-back, or buttock pain in 42 cases (77.8%) (Table 1). Bethesda, MD 20894, Web Policies and transmitted securely. Osseous union was assessed using CT scans and intraoperative findings. It is important to clinically assess the outcomes of nonoperative or surgical RF treatment. Detection and Symptoms of Broken metal rods in The present study revealed the discrepancies between CT and intraoperative findings in terms of fusion status and underlined the difficulty in assessing bone fusion.

A method for the precise assessment of bone union is required to effectively treat RF in patients with long spinal fusions. Here, we present an unusual but significant case of revision surgery to correct this complication. As they heal, they form into one bone, eliminating movement between the two vertebrae. In cases with pain, however, the pain had resolved in 19 (45%) of 42 cases within 2 weeks. In order to comprehend whether or not an individual should get a spinal fusion, it is essential to understand what the term actually means. Anekstein Y, Smorgick Y, Lotan R, Agar G, Shalmon E, Floman Y, Mirovsky Y. Orthop Clin North Am. We do not endorse non-Cleveland Clinic products or services. These are few things to keep in mind whenever an individual opts for spinal fusion surgery. Orthop Res Rev. OBJECTIVE Despite the significant incidence of rod fractures (RFs) following long-segment corrective fusion surgery, little is known about the optimal treatment 1). A satisfactory clinical outcome was observed. Injury in the nerves: Naturally, when dealing with the spine, there is always a risk Atesok K, Stippler M, Striano BM, Xiong G, Lindsey M, Cappellucci E, Psilos A, Richter S, Heffernan MJ, Theiss S, Papavassiliou E. Orthop Rev (Pavia). You may not experience any symptoms of spondylolisthesis. LLIF = lateral lumbar interbody fusion; unilateral bilateral = fracture was initially unilateral but developed into a bilateral fracture. RF occurred at the site of the 3-CO in 17 cases, posterior column osteotomy (PCO) in 20 cases, posterolateral fusion (PLF) in 11 cases, lateral lumbar interbody fusion in 1 case, and sacroiliac joint in 5 cases. Vertebral Compression Fractures The most common symptom of any spinal fracture is pain, which typically gets worse with movement. The word spondylolisthesis (pronounced spohn-di-low-less-THEE-sis) comes from the Greek words spondylos, which means "spine" or "vertebra," and listhesis, which means "slipping, sliding or movement.".

Coming to a Cleveland Clinic location?Hillcrest Cancer Center check-in changesCole Eye entrance closingVisitation and COVID-19 information. Reviewed submitted version of manuscript: all authors. In 1 patient RF occurred twice, with each case at a different time and level, and the symptoms and treatments for these 2 RFs were analyzed separately (1 case of revision surgery and 1 case of nonoperative treatment). Spinal Fracture Causes, Symptoms & Treatments - Spine Connection The distance from the odontoid tip to Chamberlain line increased to 10.5mm (it was 4.0mm after the first surgery), and subaxial cervical instability in flexion-extension increased. Comparison between CT findings and intraoperative findings in 29 cases. RF occurred twice at different times and levels in a 74-year-old female patient. Before All RFs occurred at sites with 2 rods. These treatments often relieve symptoms. During the second operation, full bone graft fusion was achieved by unicortical iliac bone graft struts and morcellized bone chips. your overall health. During the follow-up period (mean 18.5 months [range 733 months] after RF), patients were asymptomatic in 17 of the 18 cases (Fig. Regarding time to fracture occurrence after surgery, adjacent Spinal & Cervical Fusion Surgery: Purpose, Procedure, Risks Eur Spine J 24 (Suppl 7):879886, 2015, Luca A, Lovi A, Galbusera F, Brayda-Bruno M: Revision surgery after PSO failure with rod breakage: a comparison of different techniques. On October 15, 2014, although she had not experienced any trauma, the patient had increasingly severe neck pain (beginning in the previous month). Clinical evaluation after treatment of RF was not performed in all patients. There is a lack of information in the literature on this subject. Postoperative anterior spondylodiscitis after posterior pedicle screw instrumentation. Smith et al.17 also reported that 12 of 18 patients with RFs had undergone revision surgery, primarily consisting of rod replacement and repeat arthrodesis. You can tell if the screws attached are loose when a sudden pain is experienced or when you feel bulges in your spine. (Fig.1).1). The progressive loss of correction and the development of symptoms were considered in relation to the initial symptoms. This site needs JavaScript to work properly.
