Abstract：Objective To investigate the clinical results in the reconstruction of bone defects after resection of humeral shaft metastatic carcinoma by using humeral shaft prosthesis.Methods In a retrospective study,6 patients with humeral shaft metastatic carcinoma were treated with a kind of self-made humeral shaft prosthesis from May 2011 to January 2014.There were 4 males and 2 females,whose mean age was ( 57.5 ±4.8 ) years old ( range: 50-63 years ).There were 2 cases of metastases on the left side of the humerus and 4 cases of metastases on the right side.The operation time and intraoperative blood loss were recorded.The preoperative and postoperative limb pain was evaluated by the visual analogue scale ( VAS ).The postoperative limb function was analyzed with the Musculoskeletal Tumor Society ( MSTS ) system.Results The mean follow-up period was 16.5 months ( range: 6-32 months ).The mean operation time was 104.5 min ( range: 95-120 min ).The intraoperative blood loss was 491.7 ml ( range: 300-800 ml ).Postoperative recurrence in the surrounding soft tissues occurred to a patient.Another patient had aseptic loosening around the proximal end of the prosthesis,and revision surgery was performed.No such complications as radial nerve injury,brachial artery injury,inequality of upper limbs,infection or periprosthetic fractures were found,and there were no safety problems.The mean preoperative VAS score was 5.0±1.4,which was signiifcantly improved to 1.7±1.5 at 3 months after the operation,and the differences were statistically signiifcant (Ρ=0.001 ).The MSTS score was ranged from 22 to 28 with an average score of 24.8±2.1 at 3 months after the operation.Conclusions Satisfactory clinical results can be achieved in the reconstruction of bone defects after the surgical resection of humeral shaft metastatic carcinoma by using humeral shaft prosthesis.The results show that it can signiifcantly reduce pain and improve limb function with a convenient procedure,little trauma and less complication.The study offers a new palliative treatment option for the patients with humeral shaft metastatic carcinoma.
