Hip arthroplasty

Implanting quality of life with artificial hip joints

A wide portfolio of implants for primary and revision hip procedures.

Contact us

Total hip arthroplasty belongs to one of the most successful surgical interventions all over the world 1. Within the last decades major achievements have led to sustainable surgical clinical results. Advanced implant materials, reproducible surgical techniques and a high variety of specific types of components support the surgeons and the clinical teams in their daily mission to reconstruct a diseased hip joint and to improve the health of the patient.

The whole treatment process is taken into consideration, as Aesculap stands in close and continuous exchange with surgeons, medical staff, hospital management and the patient. That extends the wide portfolio of implants for primary and revision surgeries to supportive consulting offers emphasizing patients to reach independency and mobility.The results for the Aesculap prostheses, published e.g. in the German Implant Registry, 2 demonstrate its successful application in clinical use.

Acetabular cup systems

Screw Cup SC

Thin thread flanks and large pitches give more solid bone lamellae. Especially the combination of large thread distances with a good cutting-in leads to a large bone application in the thread base. The load transmission takes place evenly and without load concentrations on the thread flanks. External shape Due to the anatomical external shape of the Screw Cup SC® the subchondral bone structures remain intact. These are often destroyed in conically shaped screw sockets. The free intraoperative decision for optimal socket position is also up to the screwing of the screw cup possible, an important advantage especially in the ceramic-ceramic articulation. Cancellous bone structure  Due to the large bottom opening a central bone defect can easily be filled with cancellous bone. This sets the stage for the formation of bone in the socket base. The opening is then closed by a lid. This is firmly connected to the threaded SC® by a clamping mechanism. Cutting-in Thin thread flanks and many self-tapping edges reduce the force required for cutting the thread. Thread flanks with opposite cutting angle intersect smoother and softer in the bony implant bed. Choosing this thread parameter enables an easy and safe implantation of the Screw Cup SC®. Cutting-in depth Once the Screw Cup SC® achieved a good implant-bone contact in the thread base, special flutes grab into the bone layer. This causes a significant increase of the insertion torque. The surgeon thereby gets a tactile feedback on the final and correct screwing depth. Modular cup inserts  The conical anchoring principle of the Screw Cup® SC inner surface enables a safe anchoring of a ceramic Biolox® or polyethylene insert and thus prevents relative and micro-movements. The main load area is equipped with the maximum material thickness. The modular range of implants offers therefore the alternative: ceramic or polyethylene insert. The implant components can be individually adapted to the requirements of the patient.

Reconstruction Shell

The AESCULAP® Reconstruction Shell is intended for severe acetabular revision cases. The anatomical geometry reinforces the bony acetabular bed in the loading area. Surgeons have the option to choose between left and right versions of the implant. The outer diameter ranges from 52 up to 64 mm in 6 mm increments. The appropriate cemented polyethylene cup is fixed in place using bone cement. Vitelene® cemented PE cups are also available. The 6.5 mm fixation screws offer additional stability.
