(Ipsilateral Fractures of the Clavicle and Scapular Neck)
DefinitionA floating shoulder injury is when two of the shoulder bones are broken. The clavicle bone (collarbone) and the upper part of the scapula bone (shoulder blade) break. These breaks cause the shoulder to pull out of place and look like it is floating.

ImmobilizationA doctor may choose to use a sling or shoulder immobilizer. If this is the case, you can expect to be in a sling or immobilizer for one to two months. Your doctor may suggest physical therapy to maintain shoulder range of motion.
SurgerySurgical repair will mean inserting a plate and screws into the broken clavicle. Your scapular bone may also be fixed surgically. Your bones will be manually repositioned into their normal location during surgery. After surgery, your shoulder will be placed in a sling or shoulder immobilizer. You will be given instructions as to how long you need to wear it.Surgical repair will mean inserting a plate and screws into the broken clavicle. Your scapular bone may also be fixed surgically.
