骨，即肩下肘上之间的骨头。从肩膀下方到手腕上方，这一整段称为“肱”，俗称胳膊，是上半身两大主要支撑骨骼的统称。这类损伤可能是因坠车或马匹跌伤导致骨折碎裂，也可能是折断、斜向裂纹、完全截断或粉碎性断裂。其中，折断者伴有碎骨片，而跌断者则无碎骨片。症状表现为局部壅肿疼痛，患者心神慌乱，全身麻木发冷。治疗时均采用手法复位：顺着受伤部位上下前后的筋络进行梳理，使其调顺；按摩并按压受伤的骨缝，使其恢复平正；随后用小块杉木板在周围固定，外用白布缠绕包裹，内服正骨紫金丹，外贴万灵膏。如果壅肿不消退，可用散瘀和伤汤清洗患处。

肘骨，即胳膊中间节段上下两根骨骼交接的地方，俗称鹅鼻骨。如果跌伤导致肘尖向上突出，疼痛不止，伴有出汗和战栗，需用手法翻转臂骨，牵引肘骨使其重新合缝。对于斜弯的筋络，用手推摩使其平复。虽然此时手臂可能已经能够下垂和举起，但仍以静养休息为妙。如果出现壅肿疼痛，宜内服正骨紫金丹，外贴万灵膏。

臂骨，指从肘部到腕部有两根骨头，一正一辅。位于下方且形体较长大的，连接肘尖的称为臂骨；位于上方且形体短细的称为辅骨，俗称缠骨。这两根骨头重叠并靠，下端都连接于腕骨。凡是臂骨受伤，多是因为迎面撞击导致骨折。或者臂骨和辅骨同时断裂，或者仅断裂其中一根。由于瘀血凝结引起疼痛，需用手法将断骨对接端正，贴上万灵膏，用竹帘包裹，再用布条扎紧。三天后打开竹帘检查，用手指按压患处，如果仍有不平之处，再揉摩瘀结的部位，使其恢复原状，更换膏药，仍以竹帘包裹，每天清晨服用正骨紫金丹。

The bone refers to the bones located between the shoulder and the elbow. From below the shoulder to above the wrist, this segment is named "Gong" (Humerus/Upper Arm Bone), commonly known as the arm, which is a general term for the two major supporting bones of the upper body. Injuries may result from falling off vehicles or horses causing comminuted fractures, simple fractures, oblique cracks, complete transverse fractures, or shattered fractures. Simple fractures involve bone fragments, whereas fracture-dislocations due to falls typically do not. Symptoms include local swelling and pain, mental agitation, and generalized numbness and coldness. Treatment employs manual reduction techniques: one must trace the tendons above and below, and anterior and posterior to the injury, to ensure they are aligned and smooth; massage and press the fractured bone gaps to restore alignment; then secure with small cedar splints around the area, wrap externally with white cloth, administer Zhenggu Zijin Dan internally, and apply Wanling Gao externally. If swelling persists, wash the area with Sanyu He Shang Tang.
(Note: Zhenggu Zijin Dan, Wanling Gao, and Sanyu He Shang Tang are detailed in the section on "Injuries to the Vertex Bone".)
The elbow bone refers to the junction where the upper and lower segments of the middle part of the arm meet, commonly known as the "Goose Nose Bone". If a fall causes the tip of the elbow to protrude upward with unceasing pain, accompanied by sweating and shivering, manual reduction is required to rotate the humerus and traction the elbow bone to realign the joint. Obliquely bent tendons should be pushed and massaged back into place. Although the arm may regain the ability to hang down and lift immediately, rest and recuperation remain the best approach. If swelling and pain occur, internal administration of Zhenggu Zijin Dan and external application of Wanling Gao are indicated.
(Note: Wanling Gao and Zhenggu Zijin Dan are detailed in the section on "Injuries to the Vertex Bone".)
The forearm bones consist of two roots extending from the elbow to the wrist: the radius and the ulna. The larger, longer bone located inferiorly and connecting to the elbow tip is the ulna (Arm Bone); the shorter, thinner bone located superiorly is the radius (Auxiliary Bone), commonly known as the "Coiling Bone". These two bones overlap and lean against each other, both connecting distally to the carpal bones. Injuries to the forearm bones are often caused by direct impact leading to fractures. Either both the ulna and radius may be fractured, or only one. Stasis and coagulation cause pain. Manual reduction is used to align the broken bones correctly, followed by the application of Wanling Gao, wrapping with a bamboo mat, and tightening with cloth strips. After three days, open the mat to inspect; press the affected area with fingers. If any irregularity remains, massage the stasis knot again to restore normalcy, change the plaster, re-wrap with the bamboo mat, and administer Zhenggu Zijin Dan every morning at dawn.
