Abstract
High strength biodegradable surgical threads are in demand for surgical practice. Nowadays, such threads can be made of metallic materials such as magnesium, zinc or alloys based on these metals. In current paper, manufacturing technology of biodegradable surgical threads of Mg–Ca alloys and of pure Zn was developed and basic properties of the obtained product have been characterized. The influence of in vitro corrosion in bovine serum simulating environment in the mammal’s body on the surgical threads mechanical properties was determined. It was found that Zn and hot extruded alloys MgCa0.9 and MgCa1.2 can be recommended as a candidate for the future study in vivo. Properties of the room temperature drawn wires of the alloy MgCa0.7 are not sufficient for its application as surgical threads.
Highlights
Sterilized threads or strings use in surgery both inside and outside the body is defined by the words surgical suture and ligature
The dominant phase in these alloys has the hcp structure, space group P63/mmc and the lattice parameters nearly the same as pure magne‐ sium (i.e., a = 3.2085 A, c = 5.21.06 A, the reference code no. 01-071-3765). This indicates that this phase is a solid solution of calcium in magnesium and the calcium content in it is very small, if any, which is consistent with the equi‐ librium phase diagram Mg–Ca published by MezbahulIslam et al [58], Aljarrah et al [59], Zhong et al [60] and Baker [61]
It was shown that the corrosion products have relatively large flakes shape and poor adhesion
Summary
Sterilized threads or strings use in surgery both inside and outside the body is defined by the words surgical suture and ligature. The suture is the threads with a surgical needle attached [1]. Suture is used to stitch together the edges of various tissues, e.g., skin, fascia, muscle, tendon, perito‐ neum, etc. The surgical thread (ST) tied around a blood ves‐ sel or to constrict the tissues can be called as the ligature. There is evidence that sutures and ligatures were used by both Egyptians and Syr‐ ians as far back as 3000 B.C.E. The paper [4] describes the history of the surgery in other countries from 500 B.C.E. A historical account of sutures and ligatures can be found elsewhere. The first usage of catgut or hair as suture is dated
