韋標(biāo)方教授把學(xué)科帶入“國(guó)家隊(duì)”韋標(biāo)方教授作為股骨頭?？苿?chuàng)始人，用了20年時(shí)間，把學(xué)科打造成國(guó)家級(jí)中西醫(yī)協(xié)同旗艦科室。也就是說(shuō)，用了20年時(shí)間，把學(xué)科帶入“國(guó)家隊(duì)”。在大骨科，本無(wú)股骨頭?？萍?xì)分。中國(guó)股骨頭壞死患者人群很多病程時(shí)間長(zhǎng)，以中青年居多。在醫(yī)療2.0時(shí)代，如何去關(guān)注這個(gè)特殊群體、關(guān)愛(ài)這批人？如何讓每一個(gè)股骨頭壞死患者受益最大化？有一個(gè)人以他獨(dú)到的眼光，把它視為一種大情懷、大事業(yè)去做，把它單獨(dú)拎出來(lái)，倍加深究和考量，也把它視作自身醫(yī)療團(tuán)隊(duì)去實(shí)現(xiàn)完美逆襲的一個(gè)突破口和大機(jī)會(huì)。于是，中西醫(yī)結(jié)合治療股骨頭?？茟?yīng)運(yùn)而生，走向了春天般聚光燈下的舞臺(tái)中央。?一組數(shù)據(jù)比對(duì)，令人嘆為觀止！一個(gè)美國(guó)骨科中心，每年的診療股骨頭壞死患者有800-1000人；國(guó)內(nèi)較大的骨科醫(yī)院每年診療股骨頭壞死患者也不超過(guò)15000人；而在山東省臨沂市人民醫(yī)院股骨頭科，每年診療的股骨頭壞死患者有22000人，妥妥的遙遙領(lǐng)先，而且是以一個(gè)蓬勃上揚(yáng)的豎線生長(zhǎng)姿態(tài)，生生地把那幾家排名靠前的醫(yī)院甩開了幾條大街。以一句好理解的話可以概括為：許多需要治療股骨頭壞死的病人，大部分都去了臨沂，臨沂市人民醫(yī)院股骨頭科也成了股骨頭壞死患者最大的集散地。好多人在想，醫(yī)院好專業(yè)那么多，怎么會(huì)想到去開辟一個(gè)股骨頭?？颇?？好醫(yī)生那么多，這又是怎樣的一個(gè)牛人？在那么多好醫(yī)院中，這家是怎么做到全國(guó)遙遙領(lǐng)先的呢？他是病人眼里的好醫(yī)生，在中西醫(yī)結(jié)合治療股骨頭壞死領(lǐng)域，始終倡導(dǎo)中西醫(yī)結(jié)合“階梯化”治療，讓患者更受益；他是團(tuán)隊(duì)的主心骨，所推行的中西醫(yī)結(jié)合“階梯化”成長(zhǎng)路徑，讓每個(gè)成員都找準(zhǔn)了自己的成長(zhǎng)臺(tái)階；他是股骨頭科的創(chuàng)始人，科室從無(wú)到有、從弱到強(qiáng)，作為學(xué)科帶頭人，他一直將團(tuán)隊(duì)帶到國(guó)家級(jí)平臺(tái)。他就是臨沂市人民醫(yī)院股骨頭科韋標(biāo)方教授。中西醫(yī)結(jié)合“階梯化”治療病人有著14億人口基數(shù)的中國(guó)，醫(yī)療向來(lái)都是一個(gè)紛紛擾擾的話題，說(shuō)正話反話的都很多，繞不開的焦點(diǎn)不外乎：我們需要更好的醫(yī)療環(huán)境，我們需要更好的醫(yī)生。什么是好醫(yī)生？不同處境、不同場(chǎng)景的每個(gè)人心中都有自己的一桿秤。但幾乎可以肯定，一個(gè)不懂家庭、情感和悲喜的人，很難成為一名好醫(yī)生。試想，一個(gè)人生病，無(wú)論輕癥還是重癥，對(duì)于患者來(lái)講，事關(guān)身體，絕無(wú)小事。在這種情境下，醫(yī)生如果做不到換位思考，就很難理解病人和家屬的情形，很可能做出錯(cuò)誤的選擇，從而加深病人的傷痛。談及這些，對(duì)于股骨頭壞死的治療，韋標(biāo)方毫不回避他的定海神針——中西醫(yī)結(jié)合“階梯化”治療觀：股骨頭壞死是世界級(jí)骨科難題，單純的中醫(yī)或西醫(yī)都不能幫你解決問(wèn)題，需要中西醫(yī)結(jié)合階梯化治療，根據(jù)疾病不同階段、不同表現(xiàn)、患者個(gè)體化差異，采取不同的治療方案。在病情較輕的初期，可通過(guò)簡(jiǎn)單的中藥內(nèi)服、中藥外敷配合功能鍛煉，達(dá)到股骨頭壞死的有效控制。如果病情進(jìn)一步發(fā)展，則用保髖手術(shù)聯(lián)合中藥治療。而在股骨頭壞死后期，則需要全髖關(guān)節(jié)置換配合中藥治療。“我的股骨頭壞死治好啦，不用換關(guān)節(jié)了?！比照帐袞|港區(qū)的包女士高興地說(shuō)。包女士骨頭壞死屬于早期，韋主任用了一段時(shí)間的中藥治療，最終，包女士沒(méi)再換關(guān)節(jié)。中醫(yī)中藥治療股骨頭壞死可讓大部分早期患者不用手術(shù)，基本恢復(fù)到正常生活的狀態(tài)，韋標(biāo)方教授團(tuán)隊(duì)歷經(jīng)數(shù)十年，形成了一套成熟的股骨頭壞死診療方案。?12月底，年關(guān)將近，新年的日歷即將翻開。臨沂剛下過(guò)一場(chǎng)瑞雪，在臨沂市人民醫(yī)院的股骨頭科病房，筆者親身感受到了韋標(biāo)方團(tuán)隊(duì)的骨干們與來(lái)自天南地北患者們之間溝通的熱度。學(xué)科帶頭人韋標(biāo)方教授也在其中，忙得不亦樂(lè)乎，不是電話接個(gè)不停，就是走廊上被病人家屬“攔截”，親眼目睹了這位“最美醫(yī)生”與患者之間的“零距離”。一個(gè)病人還開了韋主任一句玩笑：“韋主任這么年輕，比電視上還要帥！”值得一提的是，線上做科普，線下做醫(yī)治，也是韋標(biāo)方的神來(lái)一筆。他通過(guò)各種傳播方式貼近病友，宣傳中西醫(yī)結(jié)合階梯化治療股骨頭壞死，僅單個(gè)社交平臺(tái)就擁有近萬(wàn)粉絲，很多外地患者，就是通過(guò)他的科普，慕名前來(lái)?，F(xiàn)在飛機(jī)、高鐵很方便，除了本省的病人、外省的患者多了起來(lái)。中西醫(yī)結(jié)合“階梯化”培育團(tuán)隊(duì)既然選擇了醫(yī)生這個(gè)職業(yè)，就要有一個(gè)成為“神醫(yī)”的理想，去成為“華佗再生”、“扁鵲再世”這樣的一個(gè)人。永遠(yuǎn)以謙卑的心態(tài)，向?qū)I(yè)大醫(yī)級(jí)的最強(qiáng)者學(xué)習(xí)，帶著團(tuán)隊(duì)向著有光的地方行進(jìn)，也讓自己成為一個(gè)有光的人。韋標(biāo)方教授在科室推行的中西醫(yī)結(jié)合“階梯化”團(tuán)隊(duì)成長(zhǎng)計(jì)劃，在管理上，首先得到了院領(lǐng)導(dǎo)的充分肯定；在專業(yè)上，在國(guó)際上得到了歐洲關(guān)節(jié)中心ThorstenGehrke教授的支持；在國(guó)內(nèi)得到了人工關(guān)節(jié)之父呂厚山教授、林劍浩教授團(tuán)隊(duì)的支持；在中西醫(yī)結(jié)合階梯化治療股骨頭壞死方面得到了全國(guó)著名股骨頭壞死診療專家、廣州中醫(yī)藥大學(xué)附屬醫(yī)院何偉教授的鼎力支持。特別值得一提的是，不論是保髖課程的普及，還是技術(shù)方向的提升等，何偉教授都給予了無(wú)私的奉獻(xiàn)和傳授。在專業(yè)上，韋標(biāo)方主任從不吝嗇自己的學(xué)究、門道和成果，毫無(wú)保留地不斷向外分享經(jīng)驗(yàn)、輸出技術(shù)，讓更多的同行認(rèn)可中西醫(yī)結(jié)合理念，讓更多患者受益。自身的醫(yī)學(xué)成就，如果能最大限度地轉(zhuǎn)化為治療價(jià)值、團(tuán)隊(duì)價(jià)值、社會(huì)價(jià)值，這是他最想看到的。韋標(biāo)方從醫(yī)40年，帶領(lǐng)團(tuán)隊(duì)診療患者10余萬(wàn)例，用20年的時(shí)間把科室打造成國(guó)家級(jí)的診療團(tuán)隊(duì)。獲評(píng)“山東好醫(yī)生”、“山東省五一勞動(dòng)獎(jiǎng)?wù)隆钡葮s譽(yù)稱號(hào)，同時(shí)獲批“山東省韋標(biāo)方教授創(chuàng)新工作室”?！笆姑鈽s，做一名永遠(yuǎn)在路上的傳承者”。這句話很好地詮釋了韋標(biāo)方教授教書育人的初心。?中西醫(yī)結(jié)合“階梯化”發(fā)展學(xué)科“我將竭盡全力，在學(xué)科建設(shè)、人才培養(yǎng)等方面，為全市、乃至全省股骨頭壞死事業(yè)發(fā)展做好支撐，打造一支高水平的學(xué)科醫(yī)療人才隊(duì)伍。”韋標(biāo)方主任說(shuō)。?在韋主任及團(tuán)隊(duì)的努力下，股骨頭科也一步步成長(zhǎng)起來(lái)，把臨沂經(jīng)驗(yàn)變?yōu)樯綎|標(biāo)準(zhǔn)，并帶領(lǐng)科室走向國(guó)家級(jí)中西醫(yī)結(jié)合旗艦學(xué)科的平臺(tái)。很多年前，臨沂的股骨頭壞死治療幾乎是一個(gè)空白，“股骨頭壞死是不死的癌癥”“股骨頭壞死很快就會(huì)癱瘓”，許多患者聽信這些傳言，到處求“偏方”，同時(shí)由于基層醫(yī)院缺乏經(jīng)驗(yàn)豐富的?？漆t(yī)生，患者往往得不到有效治療，喪失勞動(dòng)能力。在此背景下，韋標(biāo)方教授前往全國(guó)各地交流學(xué)習(xí)，不斷補(bǔ)強(qiáng)。憑借36年的臨床經(jīng)驗(yàn)，韋標(biāo)方教授團(tuán)隊(duì)總結(jié)出中西醫(yī)結(jié)合治療股骨頭壞死的成熟方案：能不手術(shù)的就不手術(shù)，能“保髖”的不換髖，需要換髖的不再勉強(qiáng)“保髖”。?“韋標(biāo)方教授及團(tuán)隊(duì)在中西醫(yī)結(jié)合治療股骨頭壞死領(lǐng)域是做出了貢獻(xiàn)的?！痹S多同行這樣評(píng)價(jià)韋主任。多家媒體采訪也表示，自從韋標(biāo)方教授在魯南地區(qū)創(chuàng)建了股骨頭科，成為了千萬(wàn)百姓的福音，越來(lái)越多的股骨頭壞死患者的健康得到了保障。韋主任卻自嘲地說(shuō)：“臨沂市人民醫(yī)院之前沒(méi)有股骨頭科也正常運(yùn)轉(zhuǎn)，但有了股骨頭科，廣大患者受益了，感覺(jué)自己及團(tuán)隊(duì)在中西醫(yī)結(jié)合治療股骨頭壞死方面做出了貢獻(xiàn)，得到了認(rèn)可?！背酥猓f標(biāo)方教授還身兼國(guó)家中西醫(yī)結(jié)合旗艦學(xué)科學(xué)術(shù)帶頭人、國(guó)際骨壞死循環(huán)研究會(huì)(ARCO)中國(guó)區(qū)資深常務(wù)委員等10余個(gè)大醫(yī)級(jí)頭銜。他很喜歡社會(huì)和病人給予他的“最美醫(yī)生”以及“好大夫”的稱謂，他感覺(jué)很親切、很踏實(shí)，也很有斗志和希望感。韋標(biāo)方教授帶領(lǐng)團(tuán)隊(duì)走向國(guó)家級(jí)學(xué)科平臺(tái)向?qū)W科帶頭人韋標(biāo)方教授及團(tuán)隊(duì)致敬，我們需要千千萬(wàn)萬(wàn)韋標(biāo)方式的“最美醫(yī)生”，好大夫。一定要說(shuō)一句感謝的話作為本次的結(ji
