Methods are provided for aesthetic restoration and reconstruction of bone loss, deficit, defect, or a combination thereof. The methods include administration of one or more suitable bone derived compositions by a minimally invasive procedure such as injection using a needle, syringe, etc., placement in or through a small incision, or a combination thereof. The properties and characteristics of the bone derived composition, including without limitation, flowability, injectability, size, shape, and physical form, are limited only by the requirement that they are capable of administration by a minimally invasive technique. For example, these methods are effective for restoration of facial features, e.g., lost chin definition, jawline definition, bone around nasal lines, and bone around the upper and lower eye area. These methods are also effective for treatment of bone deficiency and loss in other body features such as shoulders and collarbones, pelvis, feet, ankles, hands, and wrists.

This invention provides a drug solution mixing and injection device, comprising a syringe, a stirring assembly, and a needle. The syringe includes a syringe barrel with an open front end, a piston slidably mounted inside the syringe barrel, and a gap forming a cavity between the piston and the front end of the syringe barrel. The front end of the syringe barrel is provided with a sealing element, forming a sealed cavity for pre-filling drug powder. The stirring assembly is detachably mounted on the front end of the syringe barrel for stirring the mixed drug in the sealed cavity after the drug solution is injected. The needle is detachably mounted on the front end of the syringe barrel for injecting the drug solution after stirring. This drug solution mixing and injection device is compact, easy to operate, has good stirring effect, and low production cost, making it easy to promote and use.
