A　38-year-old　male　patient　suffering　from　bilateral　sternoclavicular　(SC)　joint　dislocation　with　clavicle　fracture　was　treated　with　internal　fixation　using　absorbable　screw　and　suture.　During　the　operation,　a　poly　lactic　acid　(PLA)　absorbable　screw　was　inserted　into　the　reset　SC　joint　in　a　longitudinal　direction.　Then,　polydioxanone　(PDS)　absorbable　suture　was　penetrated　through　the　bone　holes　in　the　sternum　ridge　and　the　sternal　end　of　clavicle.　The　suture　was　knotted　to　improve　the　fixation.　A　sling　to　support　the　forearm　was　used　for　three　weeks　after　fixation.　Functional　exercise　was　then　performed.　Six　months　after　the　operation,　a　score　of　11　points　was　achieved　and　postoperative　complications　did　not　appear.　The　points　given　were　based　on　Rockwood　scores　for　the　evaluation　of　clinical　effects　on　the　patient.　The　stability　of　the　joint　can　be　achieved　in　three　dimensions　and　the　secondary　surgery　operation　can　be　avoided.　Treating　bilateral　SC　joint　dislocation　using　absorbable　screw　fixation　with　an　absorbable　suture　proved　to　be　a　satisfactory　method.
