[Application progress of Sivash-range of motion femoral modular stem prosthesis in developmental dysplasia of hip and hip revision].
OBJECTIVE
To summarize the design and the biomechanical characteristics of Sivash-range of motion femoral modular stem (S-ROM) prosthesis and mainly to introduce its clinical use in developmental dysplasia of hip (DDH) and hip revision.


METHODS
Literature concerning S-ROM prosthesis was extensively reviewed and analyzed.


RESULTS
The S-ROM prosthesis based on the modularity feature can reach press-fit in metaphysis and diaphysis of femur concurrently. Additionally, S-ROM prosthesis can fit for anatomic differences of the DDH femur and is capable of use in correction osteotomy and hip revision.


CONCLUSIONS
Modular junctions of S-ROM prosthesis increase the potentials of implant fracture and metallic debris production, so further follow-up study is needed to verify the long-term effectiveness.
