Whether to suspend the affected upper limb after clavicle fracture incision-replacement internal fixation should be determined according to the condition, for stable clavicle fracture without suspension, for poor stability of comminuted fracture, suspension is needed. 1. For most of the stable clavicle fracture, after the cut-and-replace internal fixation, the stability of clavicle is better, and the anatomical structure is restored, so the affected upper limb can be left unsuspended, but we still need to pay attention in daily life, to avoid excessive force on the affected upper limb, which can lead to the loosening of the internal fixation or displacement of the fracture. 2. For patients with comminuted fracture of the clavicle, elderly patients, etc., the stability of the fracture end is poor, after incision and reduction internal fixation, it is recommended to suspend the affected upper limb, to avoid the displacement of the fracture end when moving, or cause the internal fixation to loosen or even break, etc., and it is generally required to suspend the upper limb for 4 to 6 weeks, the specific time should be determined according to the patient’s healing condition of the fracture. During the period of suspension of the upper limb, moderate rehabilitation exercises should be carried out under the guidance of the doctor to avoid the stiffness of the shoulder joint affecting the mobility after recovery.
