Hip replacement is a surgical process where natural hip joints are replaced by artificial hip joint that helps the human being for getting better lifestyle by reduction in the unavoidable pain and better leg movement. The selection of material and durability of the hip joint replacement are serious significance for the implantation, because it determines how load is transferred through the stem. In the selection of materials, various problems related to hip joint replacement are found like adverse tissue reaction, allergic reaction, wear and corrosion resistance etc. To overcome this problem one has to create different new biomaterial. This review gives brief description about the different biomaterial used for hip joint replacement.

Artificial Hip

Fungsi utama sendi panggul adalah sebagai penopang tubuh manusia dalam melakukan berbagai aktivitas dalam kehidupan sehari-hari. Secara mekanis sambungan pada sendi panggul (hip joint) merupakan socket and ball joint yang menghubungkan antara fermur head dan pelvis acetabulum. Pada banyak kasus, sendi panggul ini dapat mengalami kerusakaan permanen yang disebabkan oleh  pengapuran, penuaan atau kecelakaan. Untuk kasus yang demikian tindakan penggantian sendi panggul dengan sendi panggul buatan (artificial hip joint replacement) sangat diperlukan. Akan tetapi untuk mencegah terjadinya kerusakan maka dalam penggunaan sendi panggul buatan ini diberikan pembatasan pada beberapa gerakan, diantaranya adalah jongkok, berlari, dan salat. Pembatasan ini tentu saja akan sangat membatasi aktivitas keseharian penyandangnya. Oleh karena itu dalam penelitian ini analisis FEM sendi panggul dilakukan untuk menentukan tegangan yang terjadi pada gerakan yang dibatasi tersebut. Hasil analisis ini diperlukan sebagai pertimbangan agar dapat dirancang sendi panggul buatan yang tetap dapat memberikan kebebasan gerak bagi penyandangnya. Dalam penelitian ini pengukuran beban gaya reaksi atau ground reaction force (GRF) telah dilakukan pada kondisi saat penyandang sendi panggul buatan melakukan gerakan-gerakan salat. Gerakan salat ini dipilih karena merepresentasikan kombinasi gerakan-gerakan yang dibatasi. Hasil pengukuran GRF ini selanjutnya digunakan sebagai data beban dalam analisis tegangan menggunakan FEM. Hasil analisis menunjukkan bahswa besar tegangan  yang terjadi pada gerakan salat saat berdiri, ruku’ dan sujud masing-masing adalah 32,15 MPa; 32,46 MPa dan 21,6 MPa. Sedangkan pada saat duduk diantara dua sujud diperoleh tegangan sebesar 19,1 MPa untuk kaki kanan dan 9,3 MPa untuk kaki kiri. Adapun tegangan pada saat tahiyat akhir adalah  21,7 MPa untuk kaki kanan dan 26 MPa untuk kaki kiri

Poisson's Ratios

With the development of functional and structural materials, increasing interests have been shown in the field of biomaterials with a negative Poisson’s ratio (auxetic), which exhibit the unusual property of becoming thinner when compressed. This unusual property makes it potentially a synthetic replacement biomaterial with adequate mechanical property and wear resistance. In this study, the potential of applying the auxetic ultra-high molecular weight polyethylene (UHMWPE) for the artificial hip joint was discussed. The contact mechanics characteristics in artificial hip joint replacement under different Poisson's ratios of -1<μ≤0.5 were investigated and compared using the finite element method. The results show that Poisson’s ratio had great effect on the contact mechanics in artificial hip joint replacement. Therefore, the future work should focus on tailoring an auxetic UHMWPE with a suitable Poisson’s ratio for artificial hip joint replacements.
