A three-dimensional reconstruction model of the pelvis was developed from the chosen patient, 17 months after surgery (Fig. ). The patient had a long axis body CT scan (Philips Brilliance 64CT, Philips Healthcare, The Netherlands; slice thickness=0.7 mm, 947slices) while both lower extremities were kept in a neutral position. Because of the titanium prosthesis, the three-dimensional reconstruction model was accompanied by artifacts. We eliminated image artifacts through the difference of the gray value between the prosthesis and artifacts in the CT image. The data were then input into Mimics software (version 8.1, Materialise, Leuven, Belgium) and the three-dimensional reconstruction model of the postoperative pelvis was acquired. Because the patient’s normal pelvis could not be reconstructed directly, we obtained the normal pelvis through copying the uninjured side onto the affected side (Fig. ).

The most common cause of a hip joint disorder is increasing destruction of the joint cartilage, which can develop into arthrosis of the hip or coxarthrosis. A distinction is made between primary arthroses with largely unknown causes and secondary arthroses after certain basic disorders (congenital malformations, rheumatism, circulatory disorders, accidents or similar). The joint increasingly loses its fit, bony deposits are formed along the edges, and abrasion particles cause repeated pain. The loss of cartilage results in an increasing stiffening of the joint. At the same time, pains occurs, at first associated with initial movement after periods of inactivity and with stress, later also at night and at rest, resulting in an increasing limitation of the walking range and ultimately a reduction in quality of life.

Revascularization of a chronic total occlusion of the SFA is a relatively straightforward procedure.1 Before the operation, we discuss with the patients the possibility of performing an intervention at the time of the diagnostic procedure if there is an amenable lesion. We perform most of the procedures from a contralateral, retrograde approach but, in select cases, we use an antegrade access. The contralateral approach is easier ergonomically, and we have not found a problem with pushability. Also, unlike the antegrade approach, it does not compromise flow at the end of the procedure if the femoral artery is compressed. Full heparinization is used for all interventions, and we do not upsize the sheath until the lesion is crossed. The tip of the sheath is placed in the distal EIA. If it is advanced too far, it can obturate the vessel and cause an acute occlusion of the common femoral artery or the SFA before or after stent placement. This occurred in three of our previous cases in which the distal tip of the sheath was placed in the proximal SFA.

The present study has inherent limitations. First, the FE model was based on the anatomy of a single patient. Second, the role of muscles or ligaments was not examined because of difficulty assessing the soft tissue changes after excision and reconstruction of the pelvis. Of course, anatomical variations of the pelvis and the extent of the excision may affect the results. We hope to address these limitations in a future study.

For all three static positions, the modular hemipelvic endoprosthesis was safe and fatigue was unlikely to occur because the maximum stress was much lower than the implant’s tensile strength and yield strength. However, the stresses incurred during static positions are not the biggest stresses borne by the pelvis []. Stress borne by the pelvis is only 81 % of body weight when standing on one foot. However, stress on the pelvis increases to four to seven times body weight when walking steadily, and even ten times body weight when running and jumping [, ]. In order to analyse the biomechanics of the modular hemipelvic endoprosthesis more accurately, stresses on the pelvis while walking steadily should be investigated. That is the next study to be addressed.
