Custom‐made Prosthesis for Reconstruction after Radical Resection for Chondrosarcoma of Manubrium

Abstract

The clinical incidence of tumors in the manubrium is not high. Regardless of whether the tumor is primary or metastatic, the tumor should be completely removed as long as the patient is able to tolerate the surgery. This procedure can lead to sternal defects. Deciding on the method of defect reconstruction is a critical problem that clinicians face. In this , to reduce the limitations of the patient's upper body movement after surgery due to the inflexibility in the connections of the sternal prosthesis, we created a prosthesis using a computer-assisted design method and a 3-D technique, to completely preserve the agility of the sternum and maximize the patient's post-operational movement. The method used in the present study takes into consideration the individual's chest anatomy, sternum stress, and many other biological characteristics. Care is taken to measure the sternum size accurately, to provide personalized treatment, to accomplish precise results, and to reduce potential future damage. The patient's shoulder function was improved following the procedure.

Iterative surgical demolition and reconstruction of the anterior chest wall and thoracic outlet for a recurrent chondrosarcoma: long term oncologic and functional results

“…Sternum and ribs are affected in fifty-eight percent of cases, making it to be the most frequent primary malignant chest wall tumour. Generally, this tumour is diagnosed because of its big sizes and pain and in many cases CT scan reveals metastases (5,6). In our patient first symptom of chondrosarcoma was pain but tumefaction or nodules were not reported.…”

A newly revised pivot knee prosthesis for peri-knee malignant bone destruction tumor management

“…Technological development and improved understanding of the mechanism of carcinoma progression, together with improved staging and classi cation of the carcinoma could make some important impacts on treatment and prognosis. Presently, radically removing the tumor [4], bone grafting [18], and prosthesis arthroplasty [3,19] coupled with preoperative and postoperative chemotherapy [7] have all established advantages, although de ciencies exist in each method. One of the merits of this newly revised pivot knee prosthesis is that it could preserve the knee joint function, which may make the patient live more conveniently and con dently.…”

“…The principles for this newly revised pivot knee prosthesis arthroplasty are patient Enneking stage classi ed as equal or below B, with good topical condition, no metastasis and no important vessels or nerves involved [1,3]. A small number of patients who have heavy bone destruction of benign tumors or who have distant metastasis but are in good and healthy condition could also choose this strategy to improve their quality of life and limb functions despite reports of rare cases.…”

“…Malignant tumors that may cause bone destruction such as osteosarcoma, chondrosarcoma, Ewing sarcoma, and osteoclastoma [2][3][4][5] are generally intractable and di cult to treat because of their malignancy and metastatic nature. Previously, amputation was generally the only available method for treating malignant limb bone tumor to save people's life.…”

Innovative chest wall reconstruction with a locking plate and cement spacer after radical resection of chondrosarcoma in the sternum: A case report

“…The characteristics of chondrosarcoma include slow tumor growth, low-grade disease, extremely low rates of metastasis, and slight male predominance. Primary bone tumors located over the chest wall are rarely observed, and account for less than 1% of all primary bone neoplasms[ 3 , 4 ]. However, 15% of chondrosarcomas are located over the chest wall, with an annual incidence of 0.5 million/year[ 5 , 6 ].…”
