岐骨者，即两凫骨端相接之处，其下即鸠尾骨也。内近心君，最忌触犯。或打仆，或马撞，则血必壅瘀而多
疼痛，轻者只在于膈上，重者必入心脏，致神昏目闭，不省人事，牙关紧闭，痰喘鼻煽，久而不醒，醒而神乱，
此血瘀而坚凝不行者也，难以回生；如神不昏乱，仅瘀痛不止，胸满气促，默默不语，醒时犹能稍进饮食者，宜
早晨服加减苏子桃仁汤加枳壳，晚服疏血丸，外贴万灵膏，再以炒热定痛散熨之，庶可愈也。又凡周身骨之两叉
者，皆名岐骨，学人宜知之。

蔽心骨，即鸠尾骨也。其质系脆骨，在胸下岐骨之间。跌打撞振伤损，疼痛不止，两胁气串，满腹疼痛，
腰伛不起，两手按胸者，宜内服八厘散，外用艾醋汤洗之，敷万灵膏，渴饮淡黄酒。忌茶水、生冷、糠米粥。

凫骨者，即胸下之边肋也。上下二条，易被损伤，左右皆然。自此以上，有肘臂护之，难以着伤。在下近腹
者，用手提之易治，盖其肋近边可以着手，则断肋能复其位也，其人必低头伛腰，痛苦呻吟，惟侧卧不能仰卧，
若立起五内皆痛，或头迷神昏，饮食少进，宜内服正骨紫金丹，洗以八仙逍遥汤，贴万灵膏及散瘀等药可愈。若
在上之第二肋，或有断裂垫伤，塌陷不起，因位居膈上，难以入手，虽强为之，亦难完好，其所伤之血留于膈上，
若不随药性开行，必结成包囊。其包轻者系黄水，硬者系血块，则成痼疾矣。

岐骨，就是两侧凫骨末端相接的地方，其下方即是鸠尾骨。此处内部靠近心脏，最忌讳受到触碰或撞击。如果遭受跌打损伤或被马匹撞伤，血液必然壅滞瘀积，导致剧烈疼痛。轻症仅局限于膈肌以上，重症则会波及心脏，导致神志昏迷、双眼闭合、不省人事、牙关紧闭、痰多气喘、鼻翼扇动，若长时间不苏醒，即使苏醒后也会精神错乱，这是血液瘀结坚硬、凝滞不通所致，难以救治；如果神志没有昏迷错乱，仅仅是瘀血疼痛不止，伴有胸满气短、沉默不语，清醒时还能稍微进食的，适宜早晨服用加减苏子桃仁汤并加入枳壳，晚上服用疏血丸，外部贴敷万灵膏，再用炒热的定痛散进行熨烫，这样才有可能痊愈。另外，凡是全身骨骼中分叉的两处，都称为岐骨，学习正骨的人应当知晓。

蔽心骨，就是鸠尾骨。它的质地属于脆骨，位于胸部下方的岐骨之间。因跌打撞击震动造成的损伤，会导致疼痛不止，两胁有气窜动感，全腹疼痛，腰部弯曲无法挺直，双手按压胸部者，适宜内服八厘散，外用艾醋汤清洗，敷贴万灵膏，口渴时饮用淡黄酒。忌食茶水、生冷食物及糠米粥。
八厘散、万灵膏（均参见巅顶骨伤章节）
凫骨，就是胸部下方的边缘肋骨。上下两条，容易受到损伤，左右两侧都是如此。从这部位以上，有肘部和手臂保护，难以受伤。在下部靠近腹部的位置，用手提拉易于治疗，因为这里的肋骨靠近边缘可以着手操作，断裂的肋骨能够复位，患者必定低头弯腰，痛苦呻吟，只能侧卧不能仰卧，如果站立起来则五脏六腑皆痛，或者出现头晕神昏、饮食减少的情况，适宜内服正骨紫金丹，用八仙逍遥汤清洗，贴敷万灵膏及散瘀等药物即可痊愈。如果在上的第二条肋骨，发生断裂垫压伤，塌陷无法复原，因其位置在膈肌上方，难以入手处理，虽然强行治疗，也难以恢复完好，所伤的血液滞留于膈上，如果不随药性运行消散，必然会结成包囊。这种包囊轻者由黄水组成，重者由血块组成，就会形成顽固性疾病。

Qi Gu (Bifurcated Bone), referring to the junction where the ends of the two Fu Gu (Webbed Bone, i.e., lower costal margin) meet, is located directly above the Ji Wei Gu (Jiwei Bone, i.e., xiphoid process). Internally, it is close to the Heart (Zang organ governing spirit and blood circulation), making it highly susceptible to injury from contact or impact. Whether due to falls, blows, or being struck by a horse, blood will inevitably stagnate and form stasis, resulting in severe pain. In mild cases, the injury is confined above the diaphragm; in severe cases, it affects the Heart, leading to coma with closed eyes, loss of consciousness, locked jaw, phlegm-rapid breathing, flaring nostrils, prolonged unconsciousness, or post-awakening mental confusion. This indicates that blood stasis has become hard and coagulated, obstructing flow, which is difficult to treat and often fatal. If consciousness remains clear without confusion, but there is persistent stasis-related pain, chest fullness, shortness of breath, muteness, and the ability to consume some food when awake, it is advisable to take Jiajian Suzi Taoren Tang (Modified Perilla Seed and Peach Kernel Decoction) with Zhi Qiao (Aucklandiae Radix) in the morning, and Shuxue Wan (Blood-Dispersing Pill) in the evening. Externally, apply Wanling Gao (Ten-Thousand Spirits Plaster) and fumigate/iron the area with Chao Re Dingtong San (Heated Pain-Relieving Powder). Only then can recovery be expected. Furthermore, any bifurcating bones throughout the body are collectively termed Qi Gu; students of orthopedics should be aware of this.

Bi Xin Gu (Shielding Heart Bone), also known as Ji Wei Gu (Xiphoid Process), consists of brittle bone located between the Qi Gu at the lower chest. Traumatic injuries from falls, blows, or impacts cause unceasing pain, qi sensation radiating through both hypochondria, abdominal distension and pain, inability to straighten the waist, and a tendency to press the chest with both hands. Treatment involves internal administration of Bali San (Eight-Centigram Powder), external washing with Ai Cu Tang (Mugwort and Vinegar Decoction), application of Wanling Gao (Ten-Thousand Spirits Plaster), and drinking light yellow wine for thirst. Avoid tea, raw/cold foods, and bran rice porridge.

Fu Gu (Webbed Bone), referring to the lateral costal margins below the chest. The upper and lower pairs are prone to injury on both sides. Above this region, protection by the elbow and arm makes injury difficult. For injuries in the lower part near the abdomen, manual manipulation is easier because the ribs are accessible at the edge, allowing fractured ribs to be reduced. Patients typically exhibit head-down posture, hunched back, painful groaning, preference for lateral recumbency over supine position, severe visceral pain upon standing, dizziness, faintness, and reduced appetite. Treatment involves internal administration of Zhenggu Zijin Dan (Orthopedic Purple Gold Pill), washing with Baxian Xiaoyao Tang (Eight Immortals Freedom-Deciding Decoction), and application of Wanling Gao (Ten-Thousand Spirits Plaster) along with blood-dispersing agents for cure. However, if the second rib above is fractured and displaced, causing depression that cannot rise, treatment is difficult due to its location above the diaphragm. Even with aggressive intervention, complete restoration is unlikely. Blood stasis remaining above the diaphragm, if not resolved by medication, may form a cyst. Mild cysts contain serous fluid (yellow water), while hard ones consist of blood clots, leading to chronic, stubborn diseases.
