Mathys expands its hip portfolio with new instruments

The medical technology company Mathys, based in Bettlach, Switzerland, is expanding its portfolio in the field of hip replacement surgery with several general and specialist medical instruments. The instruments on offer support the company’s broad implant portfolio and underscore its vision of ‘Preservation in motion’. The additional instruments are available from 28 June 2021.

Portfolio expansion overview

With the expansion of the hip portfolio Mathys emphasises its claim to leadership in the field of hip replacement surgery. On the one hand, the innovations include optimised general hip instruments, which represent a valuable aid for surgeons. Beyond this, there is the addition of a new offset reamer driver, which is used in combination with an acetabular reamer to prepare the acetabulum. The medical technology company furthermore offers for the first time a chisel system for removing the optimys stem – an innovation whose form is unique on the market. The RAP hip instruments enable ergonomic explantation of all commonly used hip stems; these useful additions round off the portfolio expansion.

Valuable basic instruments for surgeons

Mathys’s proven bone retractors will be available in future in the standard version or with long soft tissue protection and the option of a handle extension. The saddle-shaped geometry reduces trauma to the soft tissue. Due to the Subtilis 2.0 surface, the instruments are more corrosion-resistant, easier to clean and thus have a longer service life. The second angle in the handle also provides a better view of the operative field. The subtle design improves the approach compared to existing retractors, especially in narrow spaces. The interconnecting radii enable the best possible distribution of pressure on muscles and soft tissues.

In addition to retractors, Mathys offers other basic instruments such as hammers, forceps, chisels, curettes, raspatories and bone spreaders, which are helpful to the surgeon as basic instruments during treatment. Many of these basic instruments are modern optimisations of the designs made together with Professor M. E. Müller in the 1950s and 1960s, which the company has optimised and further developed in close cooperation with clinical partners.

Offset reamer driver for flexible use with optimal handling

One highlight of the portfolio expansion of the offset reamer driver: this is combined with an acetabular reamer to prepare the acetabulum for implantation of the cup. The surgeon can choose from two types of acetabular reamer connection: locking or open capture. The locking option is the standard version. It also allows for reverse reaming if bone chips are to be compressed for defect filling in the acetabulum during bone grafting. The open option allows the user to connect the reamer driver to the acetabular reamer in situ and to disconnect it there as well.

In addition, the low profile construction of the offset reamer driver where it connects to the reamer enables good handling regardless of approach. The handle position can also be adjusted intraoperatively to help the surgeon achieve the best possible reaming position and force transmission.

The optimys chisel system: precise separation of bone and implant

The optimys chisel system is designed to help remove a firmly anchored optimys stem from the femoral canal while preserving as much bone as possible. For the optimys short stem, the dimensionally stable chisels with various radii enable precise separation of the bone and implant from all sides (dorsal, ventral, lateral, medial). This facilitates extraction and minimises bone loss. The handle allows the chisels to be fixed at three different lengths, enabling high flexibility and maximum force transmission.

Reduced surgery time as a result of RAP hip instruments

RAP hip instruments enable revision of a wide range of hip stems using universal and special adapters and can be used via various approaches. Surgery time can be reduced due to easy application and simple assembly/disassembly. The surgeon can generate a high axial force with the integrated guided slide weight, resulting in an excellent separation effect between bone and implant.
