序論:

急性外傷性頸胸椎接合部脊椎病変は稀な疾患であり、文献も乏しい。外傷性頸胸椎骨折脱臼の1例を報告する。頸胸椎接合部の不安定骨折脱臼に対する手術治療の経験を紹介する。.70歳の男性が当院に転院してきた。両側のC7とC8の対応する真皮層に麻痺を認めた。初期CT検査では脊柱管内への逆流を伴うT1の椎体骨折とAOSpineの軸下損傷による頚胸椎接合部C型の前方脱臼を認める。C7-T1の外傷性椎間板材料を前頸椎椎間板切除術で除去し、C6-T2を固定した。固定は仰臥位でC6からT2まで行いました。

Introduction: Acute traumatic cervicothoracic junction spinal lesions are rare disorders and poorly documented. We report a case of a traumatic cervicothoracic fracture-dislocation. We present our experience in the operative treatment of an unstable fracture-dislocation at the cervicothoracic junction. . A seventy-year-old man was transferred to our hospital. We found paresthesia in the corresponding dermatome of C7 and C8 bilaterally. Initial CT scan shows vertebral body fracture of T1 with retropulsion into the spinal canal and anteroposterior dislocation of cervicothoracic junction type C according to AOSpine subaxial injury. Traumatic disc material at C7-T1 was removed by anterior cervical discectomy and fusion of C6-T2. Fixation was done from C6 to T2 in the prone position.

結果:

術後1年の経過観察では、X線写真でC7-T1レベルの骨癒合が確認され、大きな機能障害は認められなかった。

Results: At one-year postoperative follow-up, radiographs revealed bony fusion at the level of C7-T1, and the patient had no major functional disability.

結論:

最大限の安定化と機械的合併症を防ぐために腹側-背側アプローチを選択した。

Conclusion: We opted for the ventral-dorsal approach in our case for maximum stabilization and to prevent mechanical complications.
