踝骨者， 骨之下，足跗之上，两旁突出之高骨也。在内者名内踝，俗名合骨；在外者为外踝，俗名核骨。
或驰马坠伤，或行走错误，则后跟骨向前，脚尖向后，筋翻肉肿，疼痛不止。先用手法拨筋正骨，令其复位，再
用竹板夹定跟骨，缚于 骨之上。三日后解缚视之，以枕支于足后，用手扶筋，再以手指点按其筋结之处，必
令端平。内服正骨紫金丹，灸熨以定痛散，洗以海桐皮汤，常服健步虎潜丸。若稍愈后，遽行劳动，致 骨之端，
向里歪者，则内踝突出肿大；向外歪者，则外踝突出肿大，血脉瘀聚凝结，步履无力，足底欹斜，颇费调治。
故必待气血通畅全复，始可行动。

跗者足背也，一名足趺，俗称脚面，其
骨乃足趾本节之骨也。其受伤之因不一，或从陨坠，或被重物击压，或被车马 砑，若仅伤筋肉，尚属易治；
若骨体受伤，每多难治。先以手法轻轻搓摩，令其骨合筋舒，洗以海桐皮、八仙逍遥等汤，贴以万灵膏，内服舒
筋定痛之剂，及健步虎潜丸、补筋丸。

The malleolus is the bone located below the tibia and above the dorsum pedis, presenting as a prominent high bone on both sides. The one on the medial side is named the medial malleolus, commonly known as Hegu; the one on the lateral side is the lateral malleolus, commonly known as Hegu (Note: In this context, "Hegu" refers to local colloquial names for medial/lateral malleoli, distinct from the acupoint LI4).
If injured by falling from horseback or stepping incorrectly while walking, the calcaneus may shift forward, the toes point backward, tendons are everted, muscles swell, and pain persists incessantly. Initially, manual manipulation should be used to adjust the tendons and realign the bones to restore their position. Then, bamboo splints should be applied to fixate the calcaneus and bound above the tibia. After three days, remove the binding for inspection. Support the posterior foot with a pillow, hold the tendons with hands, and use fingers to press and massage the sites of tendon knots, ensuring they are perfectly aligned. Internally administer Zhenggu Zijin Dan (Purple Gold Pill for Bone Setting), externally apply moxibustion and hot compresses combined with Dingtong San (Pain-Relieving Powder), wash with Haitongpi Decoction (Phellodendron Bark Decoction), and regularly take Jianbu Huqian Wan (Tiger-Hiding Pill for Strengthening Steps). If labor is undertaken prematurely after slight improvement, causing the distal end of the tibia to deviate inward, the medial malleolus will protrude and swell; if it deviates outward, the lateral malleolus will protrude and swell. Blood stasis will accumulate and coagulate, resulting in weakness during ambulation and tilting of the sole, making treatment difficult. Therefore, movement should only resume after qi and blood have fully recovered and circulation is unobstructed.

The dorsum pedis (Fu) refers to the top of the foot, also called Zudu, commonly known as the instep. Its bones are those at the proximal phalanges of the toes. Causes of injury vary: falling from height, being struck or crushed by heavy objects, or being run over by vehicles or horses. If only muscles and tendons are injured, it is relatively easy to treat; however, if the bone structure itself is damaged, it is often difficult to cure. Initially, gentle manual rubbing and kneading should be performed to align the bones and relax the tendons. Wash with Haitongpi Decoction (Phellodendron Bark Decoction) or Baxian Xiaoyao Decoction (Eight Immortals Free-and-Easy Decoction), apply Wanling Plaster (Ten Thousand Spirits Plaster), internally administer formulas that soothe tendons and relieve pain, as well as Jianbu Huqian Wan (Tiger-Hiding Pill for Strengthening Steps) and Bujin Wan (Tendon-Nourishing Pill).
