Summary
The cement-within-cement technique for revision total hip surgery can preserve bone by cementing a new femoral prosthesis within the existing cement mantle. Careful patient selection and planning are crucial for successful outcomes in this specialized procedure.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
Background:
- Revision total hip surgery aims to optimize outcomes and minimize bone loss.
- Established techniques for femoral component revision exist, but novel approaches are continually explored.
Purpose of the Study:
- To describe the cement-within-cement technique for revision total hip surgery.
- To outline indications and considerations for this bone-preserving approach.
Main Methods:
- This technique involves leaving an intact cement mantle in place during revision total hip surgery.
- A new prosthesis is then cemented within the existing cement mantle.
Main Results:
- Appropriate indications include a broken stem with an intact cement mantle, removal of a well-fixed stem for improved exposure or component sizing, or removal of a debonded component.
- This technique is rarely used but offers a bone-sparing option.
Conclusions:
- The cement-within-cement technique is a valuable, though infrequently utilized, option in revision total hip surgery.
- Careful patient selection, preoperative planning, and consideration of potential drawbacks are essential for successful implementation.

01:18Porosity in Cement Paste
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.

01:26Masonry Cavity Walls
Cavity walls feature a hollow space between the outer and inner wythes, connected only by corrosion-resistant metal ties. When water seeps through the outer wythe, it descends within this cavity, intercepted by flashing and eventually exiting through weep holes. To enhance moisture resistance, the inner wythe's cavity side often receives damp-proofing, doubling as an air barrier. The cavity can also house insulation to mitigate heat transfer.

01:12Total Voids in Concrete
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement ratio...
01:24Hydration of Cement
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...
01:29Mortar
Mortar, a mixture of Portland cement, hydrated lime, sand, and water, is a crucial binding material in construction. Its primary function is to join masonry units together, filling gaps and ensuring a uniform distribution of weight across the structure. This helps in preventing potential weaknesses. Mortar also serves as a protective barrier against environmental elements such as water and wind, thereby safeguarding the interior of the structure. It also compensates for surface irregularities...
01:20Cavity Drainage and Flashings in Masonry walls
Typically, a cavity wall consists of two wythes separated by a gap of at least 2 inches, which may contain insulation while still maintaining a minimum clear space of 1 inch to facilitate adequate drainage. Advanced methods like the insertion of a continuous drainage mat can further reduce this space while ensuring effective moisture expulsion.
Weep holes, strategically placed at the base of the cavity, are critical for draining accumulated water. These openings are created by leaving head...
