世人常说：医学分为十三科。各科自成专门，各自坚守师承学说，很少有能相互贯通的，这大概是大势所趋。然而各科的方论著作，作者相继出现，编纂辑录没有遗漏，唯独正体科（中医骨伤科）没有专门的书籍。难道不是接骨复位之功，精妙在于手法；而诊察按压之劳，常被轻视为粗工所为，因而无人研讨吗？从前我的毅皇帝因马匹受惊受伤，各位太医院御医因为这不是世代相传的家传医术而不能治愈，只有苏州人徐通政徐镇侍奉医药奏效，圣体恢复如初，而徐镇也由此得到赏识，官职升至九卿之列，子孙世代凭借此术在太医院任职。这其中的关系，难道是小小的事情而不值得研讨吗！况且肢体损伤于外，则气血内伤，营卫之气有所不通，脏腑因此不和，难道可以单纯依赖手法，而不探究脉理，审察虚实，从而施行补泻之法吗？太史公说：人们担忧的是疾病繁多，医生担忧的是医道稀少。我认为患处在不能贯通和融会罢了。秦越人（扁鹊）经过琅琊就去做带下医（妇科医生），经过洛阳就去做耳目痹医（五官科医生），进入咸阳就去做小儿医。这虽然是为了顺应习俗而变化，难道不是他的医道本来就能无所不通吗！立斋薛先生，以治疗痈疽继承家学，而对于各科病情变化分析入微，可以说是详尽且完备了。至于处方立论，决断生死，本来就不超出各科的范畴之外。那么求学之人，又何必担心医道稀少呢？先生曾经著有《外科枢要》，我已经为他写了序言并刻印了。现在将要重新刻印这本书，作为一家之言。我敬仰他用心的勤奋，于是又在卷首写下几句话，让后世知道先生的医术本来就没有不通晓的，而且未曾不源于一个根本道理，求学之人不要以专门某一科为由推卸责任啊。先生名己，字新甫，其官位出处详情见《外科枢要序》中，这里不再赘列。

It is commonly said that medicine is divided into thirteen departments. Each department constitutes a specialization, adhering strictly to its own school of thought, with few capable of mutual integration; this is generally the case. However, regarding the formulas and theories of various departments, authors have succeeded one another, compiling and editing without omission, yet the Department of Orthopedics (Zhengti Ke) alone lacks dedicated books. Is it not because the merit of reduction and restoration lies subtly in manual techniques; and the labor of palpation and manipulation is often disparaged as the work of crude artisans, thus neglected? In the past, our Emperor Yi suffered an injury from a horse runaway. The imperial physicians, unable to treat it as it was not a hereditary family profession, failed. Only Xu Zhen, a Tongzheng (Counselor) from Suzhou, attended to the treatment with effective results, restoring the Emperor's health to normal. Consequently, Xu gained favor and was promoted to the rank of Nine Ministers (Jiu Lie), and his descendants served in the Imperial Medical Bureau (Taiyiyuan) through generations by virtue of this skill. How can such matters be considered insignificant and left unexamined! Moreover, when limbs are injured externally, Qi and Blood are damaged internally; Ying and Wei (Nutritive and Defensive Qi) fail to circulate smoothly, leading to disharmony among the Zang-Fu organs. How can one rely solely on manual techniques without investigating pulse patterns, assessing deficiency and excess, and applying tonification or sedation accordingly? The Grand Historian stated: "What people worry about is the multitude of diseases; what doctors worry about is the scarcity of medical principles." I believe the problem lies in the inability to integrate and connect these principles. When Bian Que (Qin Yueren) passed through Langya, he practiced as a specialist in gynecology (Daixia Yi); when he passed through Luoyang, he practiced as a specialist in ear, eye, and bi-syndrome (Ermu Bi Yi); upon entering Xianyang, he practiced as a pediatrician. Although this was adapting to local customs, does it not demonstrate that his medical principle was inherently all-encompassing? Master Lizaizhai (Xue Ji), inheriting his family's expertise in treating carbuncles and sores, analyzed the variations of various departments with profound detail, being both comprehensive and exhaustive. His prescription formulation and theoretical discussions, which determine life and death, naturally fall within the scope of these various departments. Therefore, why should students of medicine complain about the scarcity of medical principles? The Master once authored *Waike Shuyao* (Essentials of External Medicine), for which I had previously written a preface for publication. Now, intending to reprint this book to preserve it as a distinct school of thought, admiring his diligent effort, I have added a few words at the beginning of the volume. This is to let future generations know that the Master's skills were universally proficient, yet invariably derived from a single fundamental principle. Students should not use specialization as an excuse for negligence. The Master's name was Ji, courtesy name Xinpu. Details of his official positions and career are provided in the preface to *Waike Shuyao*, and are not repeated here.
