Description
Shagun Cares Interference screw ( Bio Absorable) is intended for interference fixation in anterior and posterior cruciate ligament reconstruction using bone-tendon-bone or soft tissue grafts.
Bioabsorbable screws were developed as a solution to the shortfalls of metallic screws in regards to imaging, difficult hardware removal, biologic incorporation, and graft laceration. Various synthetic materials have been used to develop screws that offer strong initial fixation while retaining the ability to be replaced by bone over time. Materials used include polyglycolic acid, polyglycolic acid/polylactic acid polymers, polyparadioxanone and stereoisomers of lactic acid, poly-L-lactic acid, and poly-D-lactic acid. However, studies have shown that some of the bioabsorbable screws do not degrade at an appropriate rate and trigger inflammatory processes, resulting in tunnel widening and sometimes local effusion or tibial cysts.
More recently the Interference screw ( Bio Absorable), a subset of the bioabsorbable screw, has been developed to use familiar polymers while including additives, such as hydroxyapatite or tricalcium phosphate, to promote osseointegration. These screws have shown promise by improving screw resorption and decreasing tunnel widening when compared with the original bioabsorbable screws and metallic screws. In addition, the inflammatory changes that have been seen with the original bioabsorbable screws have not been detected in studies with the biocomposite screws, and clinical outcomes show no difference in knee stability or complications.
