在骨科的門診中,不時遇到病人投訴肩膀繃緊、活動困難,並伴隨疼痛感。肩膀是一個非常靈活的球窩關節,對上肢活動至關重要。它讓手部能到達大腦想去的位置,例如梳頭需要前舉 、穿衣要外旋、搔背則需內旋等動作。
肩膀活動受阻,會令日常生活大受影響。很多人一旦出現肩膀問題,往往以為自己患上了「五十肩」。其實,大部分五十肩在兩年時間內都能自然痊癒,但如肩膀活動功能在接受適當的保守治療後尚未有改善,很可能是出現了結構性改變,或是關節已經變形,如退化性骨關節炎、類風濕性關節炎、肩袖撕裂、或肱骨(上臂骨)近端骨折後遺症等。在這種情況下,如欲改善活動度及減輕疼痛,就可能需要進行開放式手術——「反置式人工肩關節置換術」。
這項手術只需時大約兩小時,醫生會在患者肩膀前方開一個約10至15公分的傷口,先把已變形的骨頭取出,再以一個金屬及醫用級塑膠造成的假體重建一個球窩關節。手術後一般需要佩戴一個肩部固定托約3至6個星期,再加上物理治療,肩膀很快便可重拾靈活度。很多病人在進行手術前肩膀接近完全不能活動,需要依靠另一隻手來處理日常生活,又或是經常疼痛難耐。在手術後本來不能活動的手臂恢復功能,痛楚亦消退,能夠大大提升生活質素。
即使是年長的患者,也能從這項手術中獲益。如果你或家人正面對類似問題,建議及早諮詢專科醫生的意見,尋求適切的治療方案。
