腕痈三阳风火凝，手腕背面结痈形，高肿速溃顺易治，腐烂露骨逆难功。
【注】此证生于手腕背面，属手三阳经，由风火凝结而成。高肿红活，在十四日溃破
脓出痛减者，顺而易治；手腕乃皮肉浇薄之处，若迁延日久不溃，或漫肿平塌，既溃腐
烂露骨者逆，难于收功。初服荆防败毒散汗之，外用太乙紫金绽敷之。脓成将溃，即按
痈疽肿疡、溃疡治法。

兑疽生腕动脉间，坚硬漫肿兑骨边，痛彻手膊为险证，本属肺经穴太渊。
【注】此证生于手腕里面，横纹前稍动脉之间，兑骨里侧，属肺经太渊穴，由忧思气
滞风火结成。坚硬漫肿，疼痛彻骨，手膊不能转动。此动脉处，乃肺经门户，若发此疽，
或溃深大泄肺气，最为险候。内外治法，俱按痈疽肿疡、溃疡门。

腕痈（手腕部的痈肿）由手三阳经的风邪与火邪凝结所致，表现为手腕背侧出现痈肿形态。若肿胀高起、迅速溃破，则病情顺遂，容易治疗；若腐烂并露出骨骼，则为逆证，难以治愈。
【注】此病证生于手腕背侧，归属于手三阳经，由风邪与火邪凝结而成。若患处红肿高起且色泽鲜活，在十四日内溃破流脓，疼痛随之减轻的，属于顺证，易于治疗；手腕部位皮肉浅薄，若拖延日久不溃破，或呈现漫肿平塌之象，一旦溃破后腐烂露骨的，属于逆证，难以收功。初期服用荆防败毒散以发汗解表，外用太乙紫金锭敷贴。脓液已成即将溃破时，即按照痈疽中肿疡和溃疡的治疗法则进行处理。

兑疽生于手腕内侧动脉之间，表现为坚硬且漫肿至兑骨边缘，疼痛放射至手臂为险证，其病位本属肺经的太渊穴。
【注】此病证生于手腕内侧，横纹前方稍靠里的动脉之间，兑骨的内侧，归属于肺经太渊穴，由忧思导致气机郁滞，加之风火凝结而成。表现为局部坚硬漫肿，疼痛彻骨，手臂不能转动。此处为动脉所在，乃肺经之门户，若在此处发生此疽，一旦溃破则大量耗泄肺气，最为危险。内治与外治方法，均按照痈疽中肿疡和溃疡的门类处理。
穿骨疽生于间使穴，位于手掌后方三寸处的包络经上，因蕴热凝结导致坚硬漫肿，毒势旺盛时溃破深入，穿透骨骼引起疼痛。
【注】此病证生于间使穴处，在手掌后方横纹上三寸的两条筋腱凹陷之中，归属于心包络经，由蕴热凝结而成。初起时如粟米大小，逐渐增大变硬，漫肿微红，伴有热痛，若能按期迅速溃破的，属于顺证；若溃破迟缓，脓毒溃穿骨缝，从手臂外侧流出脓液的，属于险证。内治与外治方法，均按照痈疽中肿疡和溃疡的门类处理。
Wrist carbuncle (a carbuncle occurring on the wrist) is caused by the condensation of wind and fire pathogens in the three yang meridians of the hand, manifesting as a carbuncle shape on the dorsal aspect of the wrist. If the swelling is high and it suppurates rapidly, the condition is favorable (Shun) and easy to treat; if it ulcerates with exposed bone, it is adverse (Ni) and difficult to cure.
[Note] This syndrome occurs on the dorsal aspect of the wrist, belonging to the three yang meridians of the hand, formed by the condensation of wind and fire pathogens. If the area is red, swollen, high, and vibrant in color, and suppurates within fourteen days with pus discharge and pain relief, it is a favorable case (Shun) and easy to treat; the wrist is an area where skin and flesh are thin. If it lingers for a long time without suppurating, or presents with diffuse swelling and flat collapse, and once ulcerated, becomes rotten with exposed bone, it is an adverse case (Ni) and difficult to heal. Initially, administer Jingfang Baidu San (Atractylodes and Saposhnikovia Decoction modified with Scutellaria and Isatis) to induce sweating. Externally apply Taiyi Zijin Ding (Taiyi Purple Gold Pill). When pus has formed and is about to rupture, follow the treatment principles for early-stage (Zhongyang) and late-stage (Kuyang) sores and ulcers.

Dui abscess (Dui Ju) arises between the arteries of the wrist, presenting as hard and diffusely swollen along the edge of the Dui bone. Pain radiating through the arm indicates a dangerous syndrome; its location belongs to the Taiyuan acupoint of the Lung Meridian.
[Note] This syndrome occurs on the palmar aspect of the wrist, between the arteries slightly anterior to the transverse crease, on the medial side of the Dui bone, belonging to the Taiyuan acupoint of the Lung Meridian. It is formed by qi stagnation due to worry and thought, combined with the condensation of wind and fire. It presents as hard, diffusely swollen, with pain penetrating to the bone and inability to rotate the arm. This arterial area is the gateway of the Lung Meridian. If this abscess develops here, deep ulceration leading to massive leakage of Lung Qi is extremely dangerous. Internal and external treatments follow the categories for early-stage (Zhongyang) and late-stage (Kuyang) sores and ulcers.
Bone-penetrating abscess (Chuan Gu Ju) arises at the Jianshi acupoint, located three cun posterior to the palm on the Pericardium Meridian. It is caused by the condensation of accumulated heat, leading to hardness and diffuse swelling. When the pathogenic toxin is severe, it ulcerates deeply, penetrating the bone and causing pain.
[Note] This syndrome occurs at the Jianshi acupoint, in the depression between two tendons three cun above the transverse crease of the wrist, belonging to the Pericardium Meridian, formed by the condensation of accumulated heat. Initially, it appears like a millet grain, gradually increasing in hardness, with diffuse swelling, slight redness, heat, and pain. If it suppurates rapidly according to the expected timeline, it is a favorable case (Shun); if ulceration is delayed, and pus/toxin penetrates the bone gaps, discharging from the lateral aspect of the arm, it is a dangerous case. Internal and external treatments follow the categories for early-stage (Zhongyang) and late-stage (Kuyang) sores and ulcers.
