All prostheses were customized for each patient by our clinical team and fabricated by Beijing Chunlizhengda Medical Instruments Co., Ltd (Tongzhou, Beijing, China) using the electron beam melting technique (ARCAM Q10plus; Mol̈ndal, Sweden). (Fig. 1c).

In addition, inserting Stem B into the center of the femoral head is less invasive and less technically demanding than inserting Stem A or C into the inferior or superior region of the femoral head. Therefore, the type of the rhino horn-designed uncemented stem (Stem A, B, or C) was determined by the surgeon based on patient specific factors including age, the endurance of surgery, and bone quality. For example, Stem B would be recommended for an older patient with poor cardiopulmonary function or bone quality. Otherwise, Stem A or C would be recommended.
