“…Therefore, regular screening may help clarify the cause and prevalence of odontoid abnormalities in DS patients and help prevent neurological deterioration. Screening can be accomplished by careful clinical examination and dynamic radiographs of the cervical spine in flexion and hyperextension ( 22 ). Some scholars ( 23 ) also recommended two screenings between the ages of 5–10 and 10–15 years old, respectively.…”

BackgroundTo investigate the effect of posterior atlantoaxial screw fixation for the treatment of atlantoaxial dislocation in children with Down syndrome (DS).MethodsChildren diagnosed with DS who underwent posterior atlantoaxial screw fixation or occipitocervical fusion from January 2017 to January 2020 in Hebei Children’s Hospital were retrospectively included. Preoperative CT and MRI were performed to check the os odontoideum (OsO) and spinal cord compression, signal changes and spinal cord injury grade (ASIA grade).ResultsAll 5 children have atlantoaxial dislocation and OsO. Among which 60% (3/5) of children had changes in spinal cord signals and 40% (2/5) had dural sac compression. Every child underwent posterior atlantoaxial screw fixation (3.5-mm diameter), and the average fusion level was 1.8 (1–2). All 5 cases wore the head-neck-chest brace for 3–6 months after the operation. 1 case had dural tear and recovered well after timely suturing. 1 case had internal fixation breakage of the prosthetic joint and underwent revision surgery. At the last follow-up, all cases were fused and the neurological function were all ASIA grade E.ConclusionAfter posterior atlantoaxial screw fixation, fusion and nerve recovery were achieved in all children with atlantoaxial dislocation and OsO. Postoperative head-neck-chest braces are necessary for children, especially those with occipitocervical fusion.

“…Among these ligaments we can see the transverse ligament on the Figure 6 [3]. The C1-C2 dislocation or instability in trisomy 21 may be present in the neonatal period [4]. The laxity of the transverse ligament is one of its main causes; hypoplasia, malformation or complete absence of the odontoid process is also predisposing factors [5].…”

“…This screening is recommended twice, between the age of 5 and 10 and at the age of 15 [6]. The dislocation can lead to spinal cord compression and should be investigated by dynamic radiographies in case of trisomy 21 [4]. Its signs may be: torticollis, spastic hemiparesis, quadriparesis, anal incontinence, neurogenic bladder, paresthesia; or ataxia, disturbances of equilibrium [7].…”

Spontaneous atlanto-axial (C1-C2) dislocation is an atlanto-axial instability, found in 10 to 30% of trisomy 21 patients, the majority of whom is asymptomatic. We report a case of a 21 years-old woman, with trisomy 21, admitted in our department presenting a spinal cord compression syndrome with right hemiparesis associated with a cervicalgia evolving for 3 months of admission without trauma. Standard cervical radiography showed a C1-C2 dislocation with posterior displacement of the odontoid process. A cervical computerized tomography revealed a C1-C2 dislocation with significant recoil of the odontoid process. A cervical magnetic resonance imaging (MRI) confirmed the bulbo-medullar junction compression on the dislocation. The surgical treatment consisted of a cervico-occipital fixation. The laxity of the transverse ligament is one of the main causes of C1-C2 dislocation; hypoplasia, malformation or complete absence of the odontoid process; are also predisposing factors. It must be early detected. The treatment of choice is surgical also by arthrodesis of C1 to C4 + graft and enlargement of the occipital foramen or occipito-cervical arthrodesis by synthetic graft and Cotrel-Dubousset system or occipito-C4 arthrodesis + laminectomy of C1 and enlargement of the occipital foramen.
