Congenital Elongation of the Pedicles of the Sixth Cervical Vertebra in Identical Twins

Cervical Spondylolysis, Radiologic Pointers of Stability and Acute Traumatic as Opposed to Chronic Spondylolysis

“…2,4,20 Eighteen patients had no assessment of instability before the decision for conservative treatment. 8,12,15,19,20,23 We found a direct statistical association between the presence of instability diagnosed by the lateral C-spine radiograph or after flexion/extension views and the presence of neurologic anomaly (w 2 = 34, P<0.001, DF = 1). In the patients with congenital anomalies, C6 There was one complications of conservative treatment in form of progression of the neurologic deficit, which was treated with subsequent anterior fusion.…”

“…7,8,26,32,35,36 Thirty-seven other patients had mild signs and symptoms of nerve root irritation and 28 patients had no neurologic symptoms at presentation. [2][3][4][5][6]9,[10][11][12][13][14][15][16][17][18][19][20]23,24,31,33,35,36 Sixty-eight patients had gross instability on plain radiography of the spine. The stability was assessed using flexion/extension views in another 25 patients of whom seven were found to be unstable and 18 patients were found to be stable.…”

“…5 Other authors have also supported these findings (Table 1). 2,7,10,11,[14][15][16][17][18][20][21][22][23][24][25][27][28][29][34][35][36] Congenital spondylolysis is associated with Rubinstein-Tabies syndrome or may be seen as an isolated sporadic anomaly or be inherited through a X-linked recessive or an autosomal dominant genetic condition. 5,21 The findings of Forsberg et al 5 may be disputed as a previous histologic study by Eisenstein et al 38 has shown that despite the traumatic nature of lumbar spondylolysis, the subsequent pseudoarthrosis is not a scar tissue and is a ligamentous structure with a discrete nerve supply and may resemble a developmental defect.…”

Post-traumatic c7-t1 spondyloptosis in a patient without neurological deficit: a case report

“…The etiology in this case was declared to be post-traumatic, subsequent to a significant birth trauma. Before their case, 10 more similar cases (2,5) with spondylolisthesis and spondylolysis of the cervical spine had been reported in the literature (5,3,7,14) and all were treated either conservatively or by posterior fusion alone.…”

Cervical Spondyloptosis: A Case Report

“…However, to make a precise statement about etiology is almost impossible. Although characteristic radiological features and concomitant pathologies of congenital cervical spondylolisthesis have been well documented [3,10,12,17,19,21,23], excessive latency and rarity of presentation may cause a misdiagnosis [5,7,10,12,16,17,21,24,26]. Congenital spinal anomalies are usually absent in the post traumatic subgroup.…”
