ObjectivesTo investigate the clinical outcomes of anterior cervical decompression and fusion (ACDF) surgery for the treatment of Hirayama disease (HD).MethodsIn this study, 15 patients with HD who underwent ACDF operation between March 2022 and March 2023 with complete data were retrospectively analyzed. Following the diagnosis, conservative treatment was ineffective, and thus, disease progression severely affected the quality of life (QOL) of patients. ACDF was performed in the China-Japan Friendship Hospital, and patients were regularly followed up postoperatively. The cervical range of motion (ROM), the anteroposterior and transverse diameter of the spinal cord, and their ratio was measured before and after the operation. The neurologic function of patients before and after the last follow-up was evaluated using the selected brief-Michigan Hand Questionnaire (sb-MHQ), whilst the overall therapeutic effect after the operation was evaluated using Odom's criteria.ResultsAll patients were followed up for an average of 12 ± 4.5 (6-18) months. Dynamic X-ray displayed that the ROM of cervical vertebrae decreased from 72.73 ± 12.72° (53-97°) to 33.53° ± 10.34° (15-54°) (P < 0.001). Moreover, flexion cervical magnetic resonance imaging (MRI) performed after the operation revealed that spinal cord compression was markedly relieved, and the ratio of the anteroposterior diameter of the spinal cord to the transverse diameter increased from 0.27 ± 0.09 to 0.43 ± 0.03 (P < 0.001). At the last follow-up visit, finger extension tremor symptoms were alleviated, although they did not completely disappear. Contrastingly, muscle atrophy showed no significant improvement. Finally, the sb-MHQ score significantly increased from 17.33±1.76 preoperatively to 24.80±1.78 at the last follow-up (P<0.001).ConclusionsOur results collectively highlighted the efficacy of ACDF for the treatment of HD. This procedure can limit excessive cervical flexion and repeated compression of the spinal cord during cervical movement and considerably improve upper limb functions.Copyright © 2024 Elsevier Inc.
