        <p>Dolzarblik. Kraniovertebral o‘tish sohasi travmalari neyroxirurgiya amaliyotida yuqori xavfli patologiyalar qatoriga kiradi, chunki bu sohada orqa miyaning yuqori bo‘yin segmentlari, uzunchoq miya bilan funksional bog‘liq o‘tkazuvchi yo‘llar, vertebral arteriyalar va atlantoaksial stabilizatsiyani ta‘minlovchi murakkab ligamentar-suyak kompleks joylashgan. C2 tishsimon o‘sig‘ining Anderson–D‘Alonzo bo‘yicha II-tip sinishi bitish qobiliyatining pastligi, segmentar nostabillik va orqa miya kompressiyasi xavfi yuqoriligi bilan klinik jihatdan muhim hisoblanadi. Klinik holat. Bemor balandlikdan yiqilishdan keyin bo‘yin sohasida kuchli og‘riq, qo‘loyoqlarda harakat cheklanishi, ikki tomonlama braxiopleksalgiya, uyushish va umumiy holsizlik shikoyatlari bilan neyroxirurgiya bo‘limiga yotqizilgan. Nevrologik statusda tetraparez, Frankel shkalasi bo‘yicha C daraja, McCormick bo‘yicha 3-daraja, VAS bo‘yicha 8 ball og‘riq sindromi aniqlangan. Diagnostik tekshiruvlarda C2 tishsimon o‘sig‘ining patologik sinib-chiqishi, qisman osteoliz va siljish, C1 laterolistezi, C1–C2 segmenti nostabilligi, spinal kanal stenozi va orqa miya kompressiyasi aniqlangan. Bemorga C1–C2 orqali transpedikulyar fiksatsiya, reduksiya, stabilizatsiya va dekompressiya bajarilgan. Xulosa. Mazkur klinik holat kraniovertebral o‘tish sohasi travmalarida erta MSKT/MRT diagnostikasi, standart nevrologik baholash, segmentar barqarorlikni tiklash va orqa miya dekompressiyasining muhimligini ko‘rsatadi.</p>

        <p>Relevance. Traumatic injuries of the craniocervical junction represent high-risk conditions in neurosurgical practice because this region contains the upper cervical spinal cord, neural pathways functionally related to the medulla oblongata, vertebral arteries, and a complex osteoligamentous system responsible for atlantoaxial stability. Type II odontoid fractures according to the Anderson–D‘Alonzo classification are clinically significant due to their increased risk of nonunion, instability, secondary displacement, and spinal cord compression. Case presentation. A patient was admitted to the neurosurgical department after falling from a height. The main complaints included severe cervical pain, bilateral radiation of pain to the upper limbs, restricted movements in the arms and legs, numbness, cold sensation in the extremities, sleep disturbance due to pain, and general weakness. Neurological examination revealed tetraparesis, Frankel grade C, McCormick grade 3, and severe pain scored as 8 points on the visual analogue scale. Instrumental diagnostics demonstrated pathological fracture-dislocation of the C2 odontoid process with partial osteolysis and displacement, C1 lateral listhesis, C1–C2 instability, pronounced spinal canal stenosis, and spinal cord compression at the craniocervical junction. The patient underwent C1–C2 transpedicular fixation, reduction, stabilization, and decompression. Conclusion. This clinical case highlights the importance of early CT/MRI assessment, standardized neurological grading, restoration of atlantoaxial stability, and timely spinal cord decompression in traumatic craniocervical junction injuries.</p>

        <p>Актуальность. Травматические повреждения краниовертебрального перехода относятся к числу наиболее опасных патологий в нейрохирургической практике, поскольку в этой зоне располагаются верхнешейные сегменты спинного мозга, проводящие пути, функционально связанные с продолговатым мозгом, позвоночные артерии и сложный костно-связочный комплекс, обеспечивающий стабильность атлантоаксиального сегмента. Переломы зубовидного отростка C2 II типа по классификации Anderson–D‘Alonzo имеют важное клиническое значение в связи с высоким риском нестабильности, несращения, вторичного смещения и компрессии спинного мозга. Клиническое наблюдение. Пациент после падения с высоты был госпитализирован в нейрохирургическое отделение с жалобами на выраженную боль в шейном отделе, иррадиацию боли в обе верхние конечности, ограничение движений в руках и ногах, онемение, ощущение похолодания конечностей и общую слабость. При неврологическом осмотре выявлены тетрапарез, Frankel C, McCormick 3 и болевой синдром 8 баллов по ВАШ. По данным инструментальной диагностики определялись патологический переломовывих зубовидного отростка C2 с частичным остеолизом и смещением, латеролистез C1, нестабильность C1–C2, выраженный стеноз позвоночного канала и компрессия спинного мозга. Пациенту выполнены транспедикулярная фиксация C1–C2, редукция, стабилизация и декомпрессия. Заключение. Представленный случай демонстрирует необходимость ранней МСКТ/МРТ-диагностики, стандартизированной неврологической оценки, восстановления сегментарной стабильности и своевременной декомпрессии спинного мозга при травмах краниовертебрального перехода.</p>
