Indications • All forms of osteoarthritis. • Progressive loss of function of the hip joint as a result of a degenerative posttraumatic or inflammatory/rheumatic destruction of the joint. • Femoral head necrosis. • Proximal femoral fractures (especially femoral neck). • Status following earlier operations such as osteosynthesis, intertrochanteric osteotomies, arthrodesis or failed joint replacement. Contraindications • Acute or chronic infections, local or systemic. • Severe damage to muscles, nerves or vessels that are a risk to the affected extremity. • Severe bone defects or poor bone quality, endangering the stability of the implant. • Associated disorders that could interfere with the functioning of the implant. Remark • Using hard-hard pairings, it is imperative to follow the specifications in the particular chapters. • The above-mentioned indications and contraindications apply for both primary interventions and revisions. • If a revision is performed then preferably an oversized implant should be chosen. Multihole cups can be used for difficult cases. 4
Case Study Preoperative Postoperative Female patient with dysplastic hip with OA. EP-FIT PLUS shell with SL-PLUS stem in a female patient with dysplastic hip with OA. Restoration of leg length. Preoperative Planning The surgeon uses the radiographic template (15% enlarged) to plan • The intended size of the implant. • The ideal position of the shell in relation to the acetabular teardrop figure. Note Exact determination of the size of a shell preoperatively using radiographic templates is only possible to a certain degree. In general, the removed femoral head gives a good indication of the size of the acetabular cup. With a normal acetabulum, the definitive size of the shell is 4–6 mm larger than the anteroposterior diameter of the removed femoral head. The correct shell size is finally judged on the basis of the definitive reamer size/the correct trial shell. 5
