Description
Technical field
The invention belongs to Orthopeadic Surgery osteotomy orthoses field more particularly to CAD individuation artificial body of the humerus and
Production method.
Background technique
Metaphysis of the proximal humerus as upper limb is common site and the most common portion of metastatic carcinoma of primary tumor
One of position and sarcoma third common site.Common tumour has: metastatic carcinoma, osteosarcoma, chondrosarcoma, giant-cell tumor etc..Greatly
There are about 50% upper limb sarcomas to appear in omoplate zone.According to the grade malignancy of each tumour, recurrence rate, prognosis etc. it is a variety of because
Element, the selection of therapeutic modality are also different.Proximal humerus malignant tumour was often treated with amputation in the past, only to low potential malignancy
Tumour give limb salvage treatment.Reported since 1977 limb-sparing surgery it is similar to amputation curative effect after, more and more surgeries
Doctor treats the malignant tumour of proximal humerus with limb-sparing surgery, and finds long term survival rate without too big influence.In recent decades,
Limb-sparing surgery has very big development in the position malignant tumour surgical intervention.And for the operation of limb salvage treatment, hand
It is prerequisite that art, which is obtained without tumor boundary, while being also an important factor for avoiding local recurrence.However postoperative function is also surgery
Doctor needs to consider the problems of emphatically.Therefore the tumor resection for focusing on guaranteeing enough ranges of limb-sparing surgery and preservation are important
Balance is kept between structure and function.Limb-sparing surgery mainly includes the excision of tumour, the reconstruction of bone defect and surrounding soft tissue's weight
It builds.And for tumor resection after, the reconstruction of bone defect is an important procedure during limb-sparing surgery again, is soft tissue
Reconstruction provides mechanical foundation, and reconstruction mode specifically includes that artificial prosthesis reconstruction, homogeneous allogenic bone transplantation composite prosthesis weight
It builds, Fibula autograft reconstruction, the clavicle rotation shifting of bone and osteochondral allograft, arthrodesis of shoulder, implantable intravascular or non-vascularization
Position reconstruction etc..Wherein, and with what artificial prosthesis was rebuild it is most widely used.Its reason may include prosthese function admirable, suffer from
