Abstract

The invention discloses a proximal humerus head-preserving and prosthesis conversion treatment device. The device includes a head bracket. The upper end of the head bracket is embedded in the femoralhead, the lower end of the head bracket is fixed in an intramedullary handle body, the head bracket is internally provided with a lag screw, and a lock pin is arranged in the intramedullary handle body and passes through the intramedullary handle body. The device can effectively and flexibly select head-preserving treatment or non-head-preserving treatment, the complexity of surgery is reduced, the cost of the surgery is reduced, and a safe environment is created for reserved secondary surgery when necrosis occurs later.

Description

technical field [0001] The invention belongs to the field of humerus medical devices, in particular to a proximal humerus head retaining and prosthesis conversion treatment device. Background technique [0002] When the patient has severe humeral four-part fracture, humeral head-preserving / non-head-preserving refractory fracture, anatomical neck fracture / head dislocation senile fracture, severe osteoporotic three-to-four-part fracture through the greater tuberosity, and head splitting For shoulder fractures in the five types of fractures, conventional surgical treatment methods, whether it is plate screw fixation or intramedullary nail fixation, are difficult, complicated fixation, high risk of late necrosis, and poor surgical results. Revision surgery has insurmountable difficulties. Especially frail elderly patients. Overly complicated operations (internal fixation and secondary implantation of prostheses) are unbearable for the patient, and even life-threatening, bringi...
