脊椎外科班

脊椎グループの概略

 脊椎グループは一昨年より、学内スタッフは出村、加藤仁志先生、新村和也先生、横川文彬先生の4名体制でしたが、本年4月より新村先生が石川県立中央病院へご栄転され、大学病院は出村、加藤、横川のスタッフ3名体制となりました。新村先生は大学在任中、持ち前の素晴らしい手術技術を生かして、脊椎内視鏡手術に加え、高難度の手術も数多くこなされました。さらには後輩の指導や、学生勧誘、宴会隊長など、書面での業績には表れない多くの活躍をされてきました。4月から学内は少し寂しくなりますが、石川県中でも更に大活躍されると確信しておりますし、学内も少しでも新村先生の穴を埋められるように頑張っていきたいと思います。
昨年度は半田真人先生、安念遼平先生の学位研究がすすみ、現在学外大学院生として帰学しながら研究の仕上げに取り掛かっております。学内大学院生は小林源哉先生、山田遥平先生、長谷賢先生に加え、4月から河合雅文先生が関連病院のローテートを終了し新たなメンバーとして加わりました。

臨床

2021年の脊椎班の手術件数ですが、大学病院でのコロナ対応に伴う手術件数の制限により、160件と例年よりもかなり減少してしまいました。同門の先生方、関連施設の先生方からは多くの患者さんをご紹介頂いたにもかかわらず、手術待機期間が延長していることを心からお詫び申し上げます。ただ昨年も大きなトラブルなく乗り切ることが出来ました。ご紹介頂いた先生方、スタッフの先生方、病棟を頑張ってくれた若手の先生方に感謝申し上げます。手術の内訳としては脊椎・脊髄腫瘍、側弯症、後弯症などの脊柱変形、脊柱靱帯骨化症、変性疾患に対する低侵襲手術が例年通り多くを占めておりました。

外来は火曜日と木曜日の午前中に各3名が担当し、1日約50-60人の患者さんを診察しています。基本的には、脊椎疾患全般、側弯症などの脊柱変形を出村が担当し、脊椎腫瘍、靭帯骨化症、腰痛症を加藤先生が、脊椎疾患全般を横川先生が担当しています。

また毎週木曜日の夜には医局で症例検討会を行なっております。大学内での手術症例や、学外での手術に迷った症例など、1例1例を全員で検討しています。毎月第1週には大学院生の研究報告、第3週には臨床研究に関する検討会も継続し、順調に研究が進んでおります。コロナ対応に伴う数少ない良い点として、オンラインカンファレンスに切り替わったことがあります。学外の先生方が大学にお越しになられずに、症例のご相談が出来るようになりましたので、気軽にオンラインでもご参加いただければ幸いです。

研究

脊椎班の基礎・臨床研究に対する方針は従来からの脊椎班の方針を引継ぎ、『臨床で遭遇した疑問・問題点を研究で解決する』というテーマですすめています。まず、五十嵐峻先生は放射線照射が脊椎の骨強度に与える研究を終了し昨年10月に論文がアクセプトされ、学位を取得されました。米澤則隆先生は、液体窒素処理骨移植が全身のがん免疫に与える影響を基礎と臨床の両面から研究し、基礎実験に関しての英語論文がアクセプトされ、学位を取得しました。北川亮先生は加藤先生が開発した体幹筋トレーニングベルトの腰痛改善効果を前向きに臨床研究で調査し、学位論文としてアクセプトされ、学位を取得されました。ここ3年間で脊椎班では6名の先生方が学位を取得され、非常に良い流れで研究が進んでいると思います。

学外の奥規博先生は龍谷大学理工学部との共同研究で骨粗鬆症性脊椎における多椎体脊椎固定術の力学的解析の良い結果がまとまり、論文投稿を行いました。半田真人先生は、新たな側弯症マウスの特徴を調べており、基礎実験はほぼ終了したため論文作成に取り掛かっております。安念遼平先生は、米澤先生の継続実験として転移性骨腫瘍モデルに凍結処理を施行し、対側の腫瘍の縮小効果を確認しており、ほぼ実験は終了に近づいております。学内大学院の小林源哉先生は、脊椎腫瘍を想定し、凍結処理プローブを用いた脊髄に対する安全性を検討しており脊髄への安全域がほぼ確立されそうな状況です。山田遥平先生は、骨に高圧処理を加えることによる、脊椎腫瘍の死滅効果や骨癒合に関して検討を京都大学との共同研究ですすめており、高圧処理骨の有用性を検証しております。長谷賢先生は半田真人先生の継続実験で、側弯症マウスの骨代謝や介入研究を開始しております。

以上、脊椎グループの現状を紹介させて頂きました。
