Proximal humerus fractures are a clinically common fracture type, accounting for about 2% of each fracture. The most common in elderly osteoporotic patients is often caused by low energy injury. With the increasing aging of population, the elderly patients with proximal humeral fracture in clinic are increasing. For patients with older ages and surgical contraindications (such as combined three or more medical diseases, such as hypertension, diabetes, coronary heart disease and the like), or patients with extremely poor cardiopulmonary functions and patients who cannot tolerate anesthesia or surgery, the traditional conservative treatment, namely olecranon traction treatment, can only be carried out clinically without adopting surgical treatment.

The traditional olecranon traction treatment requires that the patient is bedridden, namely, the forearm of the patient is hung on the top of the head, the elbow joint is kept to bend 90 degrees, and the traction suspension is carried out on the extension line of the inner edge of the humerus stem (namely, 3cm below the olecranon), so that the recovery line of the patient limb is realized, and the purpose of traction treatment is achieved. Because the bone traction time is long, the patient can have great pain when keeping the posture for a long time, the life quality is seriously affected, and a plurality of inconveniences are brought to the daily life of the patient. Meanwhile, a series of complications such as bedsores, falling pneumonia, myodynamia hypodynamia, deep vein thrombosis and the like, which are possibly caused by long-term bedridden traction of old humerus proximal fracture patients, are considered, and if the complications are incorrectly treated, irrecoverable risks are left.
