SHY CUP

Product catalog summary

Acetabular Exposure and Reaming
The procedure for acetabular exposure and reaming emphasizes the use of Hohmann retractors or Steinmann nails for wide exposure. It involves cleaning soft tissues to achieve a clear view of the acetabulum. Reamers of increasing size are used to remove cartilage and subchondral bone, ensuring a bleeding surface while preserving bone stock. The reaming position is specified at 45º lateral inclination and 15º anteversion.

Trial of the Acetabular Component
The trial involves selecting an acetabular cup matching the last reamer size, with the final implant oversized by 2 mm for better fixation. Trial components help determine the best fit and coverage for each patient.

Surgical Technique
Patient positioning varies between lateral or supine decubitus based on the surgical approach. The document details the insertion of the acetabular cup using an impactor, with specific angles for inclination and anteversion. Optional screw fixation is discussed to enhance stability.

Polyethylene Cup Introduction
The polyethylene cup's anti-dislocation lip can be angled variably to prevent dislocation, with recommendations based on surgical approach. Anterior positioning is advised against due to potential interference with prosthesis movement.

Implants and Components
The document describes the modular acetabular system, including titanium cups and polyethylene inserts. Features include the anti-luxation lip, conical trunk design for stress dispersion, and clip fixation to prevent loosening. Details on screw specifications and assembly instructions for the cup impactor are provided.

Specifications
The hemispheric cup is constructed from titanium (Ti6Al4V) with a ridged section for primary attachment, complemented by Ø 6.5 mm low profile titanium screws. The cup is coated with titanium plasma spray and Hydroxyapatite (HA) to promote osteoinduction and osseointegration.

Design Features

The top hole allows for verification of implant-bone contact.
Three additional holes enable reinforced attachment using Ø 6.5 mm screws if necessary.
Peripheral slots increase the base diameter for primary 'pressfit' stability and enhance bone-implant surface area.
Extraction slots facilitate the removal of the insert.
An internal diameter groove aids in anchoring the implant.

Instrumentation
The document lists various instruments and their references, including the S.H.Y. cup instrumentation set, acetabular reamers, and hexagonal screwdrivers.

Distribution
The product is distributed by a company located in Paterna, Valencia, Spain, with contact details provided for further inquiries.

Montaje del impactor de cotilo Assembly of the cup impactor Inserto de polietileno Polyethylene insert 6. El Inserto no excede por encima de la línea de cotilo, a excepción de la ceja antiluxante de 15º, con el fin de ampliar al máximo el rango posible de movimientos de la prótesis. El espesor del Inserto siempre será mayor de 5 mm, incluso en las tallas más pequeñas. Para el correcto montaje del impactor, las pestañas (señalizadas mediante dos flechas en la parte inferior, fig. 1a) deben encajarse perfectamente dentro de las ranuras del componente acetabular (fig. 1b) hasta comprobar que éste...
