后山即头后枕骨也。其骨形状不同，或如品字，或如山字、或如川字，或圆尖，或月芽形，或偃月形，或
鸡子形，皆属枕骨。凡有伤损，其人头昏目眩，耳鸣有声，项强咽直，饮食难进，坐卧不安，四肢无力，内服
正骨紫金丹，外敷乌龙膏，洗以海桐皮汤，以散瘀去麻木止痛。如误从高处坠下，后山骨伤太重，筋翻气促，痰
响如拽锯之声，垂头目闭，有喘声者，此风热所乘，至危之证，不能治也，遗尿者必亡。惟月芽形者，更易受
伤。如被坠堕打伤，震动盖顶骨缝，以致脑筋转拧疼痛，昏迷不省人事，少时或明者，其人可治，急以凉水蘸
发，启开牙关，以酒调八厘散灌之，服后目开痛苦有声，二目流泪，愈见可治之兆，服正骨紫金丹，炒米粥调养
可愈。

寿台骨，即完骨，在耳后接于耳之玉楼骨者也。若跌打损伤，其耳上下俱肿起，耳内之禁骨有伤，则见血脓水，
耳外瘀聚凝结疼痛，筋结不能舒通，以致头晕眼迷，两太阳扶桑骨胀痛，颈项筋强，虚浮红紫，精神短少，四肢无力，
坐卧不安，饮食少进。以乌龙膏敷耳伤处，用丝棉裹导气通瘀锭塞耳内；内服人参紫金丹，通瘀散肿；外用以八仙逍
遥汤熏洗，消散虚浮肿痛。忌食热物发物。如血流不止，三日不饮食，必动脑髓，不宜治之。

The "Houshan" bone refers to the occipital bone at the back of the head. Its shape varies; it may resemble the Chinese character "Pin" (品), "Shan" (山), or "Chuan" (川); it may be round and pointed, crescent-shaped, inverted-crescent-shaped, or egg-shaped. All these forms belong to the occipital bone. In cases of injury, the patient experiences dizziness and vertigo, tinnitus with audible sounds, stiffness of the neck and tightness of the throat, difficulty in swallowing food, restlessness in sitting and lying down, and weakness in the four limbs. Internally administer Zhenggu Zijin Dan (Orthopedic Purple Gold Pill), externally apply Wulong Gao (Black Dragon Ointment), and wash the area with Haitongpi Tang (Pterocarpus Bark Decoction) to dissipate blood stasis, relieve numbness, and alleviate pain. If a fall from a great height causes severe injury to the Houshan bone, resulting in tendon dislocation, shortness of breath, rattling phlegm sounding like sawing wood, drooping head with closed eyes, and wheezing, this indicates an invasion by wind-heat pathogen, representing a critical and incurable condition. If urinary incontinence occurs, death is inevitable. The crescent-shaped occipital bone is particularly susceptible to injury. If struck by falling objects or blows, causing vibration to the sutures of the cranial vault bones, leading to twisting pain of the brain nerves, coma, and loss of consciousness, but regaining consciousness after a short while, the patient can be treated. Immediately wet the hair with cold water, pry open the jaw, and administer Bali San (Eight-Centigram Powder) mixed with wine. If, after administration, the eyes open, the patient groans in pain, and tears flow from both eyes, these are signs indicating that treatment is viable. Subsequently, administer Zhenggu Zijin Dan and nourish the body with stir-fried rice porridge for recovery.

The "Shoutai" bone, also known as the Wanggu (Complete Bone), is located behind the ear and connects to the Yulou bone of the ear. If subjected to falls or blows, swelling will occur above and below the ear. If the Jin bone inside the ear is injured, blood, pus, and fluid will discharge. Externally, blood stasis accumulates and condenses, causing pain, and tendons become knotted and unable to relax, leading to dizziness and blurred vision, distending pain in the Fusang bones at the two temples, stiffness of the neck and nape muscles, flaccid redness and purpleness, diminished spirit, weakness in the four limbs, restlessness, and reduced appetite. Apply Wulong Gao to the injured ear area; wrap cotton silk around Daoqi Tongyu Ding (Qi-Dredging and Stasis-Resolving Plug) and insert it into the ear canal. Internally administer Renshen Zijin Dan (Ginseng Purple Gold Pill) to dredge stasis and reduce swelling. Externally fumigate and wash with Baxian Xiaoyao Tang (Eight Immortals Soothing Decoction) to dissipate flaccid swelling and pain. Avoid hot foods and triggering foods. If bleeding does not stop and the patient abstains from food and drink for three days, the brain marrow will likely be disturbed, making the condition untreatable.
