In western developed countries such as Europe and America, breast cancer has become one of the main causes of death for women. In recent years, the incidence of breast cancer in China has risen to the second place in the female cancer. Throughout the history of the treatment of breast cancer in the past hundred years, surgery is still the main treatment for breast cancer. Since the 1960s, modified radical mastectomy has rapidly replaced standard radical mastectomy as the standard surgical treatment for breast cancer. Modified radical surgery for breast cancer requires breast skin, subcutaneous tissue and mastectomy, and axillary adipose and lymphatic tissue dissection. Due to the large operation scope, large trauma and high incision tension, postoperative shoulder dysfunction and other sequelae may occur, and even lead to the patients' daily living activities disorders. It is of great significance to properly protect the affected limbs and exercise their functions in the early stage. Through planned functional exercise and rehabilitation guidance, the degree of limb edema can be effectively reduced, function loss can be avoided, and normal limb function can be achieved. December 2010, I division will be applied to breast cancer postoperative rehabilitation division shoulder brace limb shoulder of brake, change the traditional breast cancer surgery using pillow limb braking method of the shoulders, so as to reduce the incidence of breast cancer postoperative subcutaneous effusion, shortening time of postoperative catheter and promote healing of incision, relieve patients' pain and economic burden.

The shoulder orthopaedic device strictly controls the movement of the affected limb, which can promote wound healing and reduce subcutaneous effusion. The modified radical mastectomy for breast cancer has a large wound surface and a long healing time for the postoperative incision. It is reported that the time required for the incision healing after the modified radical mastectomy for breast cancer is 10-35d. Because the incision is close to the armpit, improper fixation of the shoulder and arm after surgery will lead to poor incision healing and subcutaneous effusion, increasing the pain and economic burden of patients. Boostrom et al. reported that the incidence of subcutaneous effusion after breast surgery requiring clinical treatment was 2%-16%. It was also reported that the incidence of subcutaneous effusion after breast cancer surgery was 6%~42%. It has been reported in the literature that there are many methods to prevent subcutaneous hydrops after breast cancer surgery, mainly through pressure dressing, subcutaneous placement of low negative pressure drainage tube, combined with early postoperative shoulder immobilization and other methods, so as to reduce the incidence of subcutaneous hydrops. Patients in the control group to prepare the pillow size, shape and thickness is not uniform, due to the quality in use and easy to deformation, so the limb shoulder abduction Angle is not unified, and some patients compliance is poor, often forget to use pillows to early postoperative limb activity at random, the growth of the influence between the flap and chest wall, leading to high incidence of subcutaneous effusion. In the observation group of patients with shoulder joint orthoses by setting up appropriate changes in different periods according to the condition of shoulder abduction Angle to strictly control the early postoperative limb of the shoulder joint activity, more convenient, fixed side body scientifically, can effectively control arm patients at random, limit referred pain caused by limb unconscious activity, Avoid excessive lifting of the upper arm, abduction of shoulder joint and excessive adduction and other activities, firmly fix the affected limb, there will be no limb slippage phenomenon, to prevent skin flap movement and affect wound healing, reduce the occurrence of postoperative subcutaneous fluid accumulation.

Because of the particularity of the modified radical mastectomy site for breast cancer, the normal physiological activities of the body are greatly limited. Control group in the use of traditional square pillow, often forget the affected limb braking and forearm because there is no support point easy fatigue, resulting in the affected limb shoulder joint easy to involuntary excessive activity, these factors will increase the incidence of pain and pain degree, thus affecting the comfort of patients. Observation group used material for the import of plastic, shoulder brace worn very deft, limb can be directly put on the support plate, excellent mechanical design makes one side shoulder to the elbow in a state of relaxation, relieve the forearm fatigue, relieve the patient and family to keep a specific position caused by the continuous tense psychology, improve the patient's comfort.
