Titanium is a very strong metal, as strong as steel but it is 45% lighter which means it is very practical for the patient. Also titanium is very non-reactive which means that the normal body fluids wouldn't attack it. On top of that, titanium can take a lot of wear and tear before it finally gets ruined or corrodes which means it is a perfect replacement for a joint, especially a hip joint.
Usually a tantalum (Ta) or titanium (Ti) coating is used on a stronger metal like steel
If medial hip rotators are tight, then they will impede lateral hip rotation because lateral hip rotation requires the medial hip rotators to stretch to allow the lateral hip rotators to contract and rotate the hip laterally.
The hip is a ball and socket joint.
Titanium is corrosion resistant, very strong and has a high melting point. It has a relatively low density (about 60% that of iron). It is also the tenth most commonly occurring element in the Earth's crust. That all means that titanium should be a really important metal for all sorts of engineering applications.In fact, it is very expensive and only used for rather specialised purposes.Titanium is used, for example:in the aerospace industry - for example in aircraft engines and air frames;for replacement hip joints;for pipes, etc, in the nuclear, oil and chemical industries where corrosion is likely to occur.Why is titanium so expensive?Titanium is very expensive because it is awkward to extract from its ores - for example, from rutile, TiO2.You can't use carbon reductionTitanium can't be extracted by reducing the ore using carbon as a cheap reducing agent. The problem is that titanium forms a carbide, TiC, if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle.That means that you have to use an alternative reducing agent. In the case of titanium, the reducing agent is either sodium or magnesium. Both of these would, of course, first have to be extracted from their ores by expensive processes.Other problemsThe titanium is produced by reacting titanium(IV) chloride, TiCl4 - NOT the oxide - with either sodium or magnesium. That means that you first have to convert the oxide into the chloride. That in turn means that you have the expense of the chlorine as well as the energy costs of the conversion.Titanium(IV) chloride reacts violently with water. Handling it therefore needs care.Traces of oxygen or nitrogen in the titanium tend to make the metal brittle. The reduction has to be carried out in an inert argon atmosphere rather than in air. That also adds to costs.High temperatures are needed in both stages of the reaction.Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something.With titanium, however, you make it one batch at a time. Titanium(IV) chloride is heated with sodium or magnesium to produce titanium. The titanium is then separated from the waste products, and an entirely new reaction is set up in the same reactor. This is a slow and inefficient way of doing things.Titanium extractionConversion of titanium(IV) oxide, TiO2, into titanium(IV) chloride, TiCl4The ore rutile (impure titanium(IV) oxide) is heated with chlorine and coke at a temperature of about 900°C.
The titanium is very light.
because it is nontoxic
Titanium
Yes, the majority of them have some in. Typical a Titanium-vanadium alloy
Yes. Titanium is a metal that does not cause allergies. Gold and Platinum also do not cause allergies. However, Titanium is stronger and less expensive. So you can use all the Titanium you wish.

This is true, however it is not the only reason titanium is used for hip joints. It is also very strong and significantly lighter than steel.
it is strong :)
it's non-toxic.
used for implants such as hip joints also surgical equipment
It is non-toxic, durable and lightweight.
