Rotatory Fixation

In cases of chronic irreducible and recurrent unstable atlantoaxial rotatory fixation (AARF), closed reduction and its maintenance are often unsuccessful, requiring surgical treatment. The purpose of the present report is to describe a rare case of pediatric AARF that required multiple treatments. A 6-year-old boy was diagnosed as having type 2 AARF. After conservative treatment, the patient was treated with temporary fixation surgery (C1-C2 Magerl) without a bone graft in consideration of motion preservation after screw removal. AARF recurred after the screw removal and required fusion surgery (Magerl–Brooks) with an iliac bone graft. Ultimately, bone union was achieved and the screws were removed 11 months after the surgery. We recommend surgeons be cautious when choosing temporary fixation surgery for AARF in small children. Further investigation is needed to determine the optimal time before screw removal.

Rotatory Fixation

Background: Tubercular atlantoaxial, rotary dislocation warranting fixation (AARF) is an extremely rare event. Case Description: AARF was suspected in a 23-year-old female with painful torticollis. When diagnostic studies documented unilateral destruction of the left lateral mass of the atlas, she underwent removal of the lateral mass, reduction of the deformity, and C1-C2 fusion/reconstruction utilizing an iliac bone graft. Laboratory tests and the pathologic surveys were all consistent with the diagnosis of underlying tuberculosis. Conclusion: We present a case of tubercular atlantoaxial, rotary dislocation (AARF) in a patient who warranted C1-C2 decompression, reduction, and fusion.

Secondary chondrosarcomas according to malignant transformations of the solitary enchondromas were extremely rare in the hand. The aim of this study is to present a case of a 43-year-old male having rare malignant transformation of the solitary enchondroma treated with total excision and replacement with iliac bone graft.

✓ The authors report on a 31-year-old man with spontaneous craniocervical osseous fusion secondary to cervical dystonia (CD). After an 8-year history of severe CD, the patient developed a fixed rotation of his head to the right. Three-dimensional computerized tomography reconstructions revealed rotation and fixation of the occiput and C-1 relative to C-2, which was similar to that seen in atlantoaxial rotatory fixation. There was abnormal ossification of the odontoid facet joints and ligaments. Additional ossification was observed in the cervical soft tissue bridging the lateral mass of C-1 and the occiput. The patient underwent partial myectomy of the dystonic left sternocleidomastoid muscle and selective posterior ramisectomy of the right posterior neck muscles; postoperatively he experienced relief of his neck pain. In patients with CD refractory to conservative treatment, the appropriate timing of surgical treatment is important.

This study aimed to explore the safety and efficacy of using nano-hydroxyapatite/polyamide (N-HA/PA) composite in anterior cervical vertebral body subtotal corpectomy and interbody fusion. Total 50 patients with cervical spondylotic myelopathy were enrolled to undergo anterior cervical spondylectomy. Bone graft pedicles were compounded with N-HA/PA and intervertebral body fusion was performed. Study outcomes included surgical efficacy and the degree of fusion. Patients in whom vertebral body fusion was performed with N-HA/PA composite pedicles had significantly improved symptoms. The postoperative Japanese Orthopaedic Association scores increased to 18.56±4.37 from 11.37±3.52, reflecting an improvement rate of 87.3%. The composite pedicle fusion rate was 96.4%. Therefore, N-HA/PA composite pedicle as a bone graft material in fusion surgery provides significant therapeutic efficacy. Moreover, the composite pedicle fusion rate is high, making it ideal for anterior cervical vertebral body subtotal corpectomy and fusion.
