Summary
The stump lengthening procedure (SLP) offers a viable alternative to hip disarticulation, improving function and appearance without increasing cancer recurrence. While complications occur, SLP enables ambulation with exoprostheses.
Area of Science:
- Orthopedic surgery
- Surgical oncology
- Rehabilitation medicine
Background:
- Hip disarticulation is a challenging procedure for sarcoma, infection, or trauma when limb salvage is not possible.
- Stump lengthening procedure (SLP) allows partial thigh salvage with endoprosthetic replacement after hip disarticulation.
- SLP enhances cosmetic appearance, prosthetic fitting, and limb function.
Purpose of the Study:
- To describe indications for SLP.
- To detail the surgical technique of SLP.
- To present clinical and functional outcomes of SLP.
Main Methods:
- Literature review on SLP.
- Presentation of outcomes from a cohort of SLP patients.
Main Results:
- SLP does not increase local recurrence risk compared to hip disarticulation.
- Most patients use exoprostheses for ambulation, often with walking aids.
- Common complications include periprosthetic infection (21%) and soft tissue perforation (14%).
Conclusions:
- SLP is a feasible alternative to hip disarticulation, offering good cosmetic and functional results.
- SLP does not compromise local tumor control.
- Patients achieve ambulation with exoprostheses, though walking aids may be needed, especially for older patients.

01:31Formation of Species
44.9K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

37.1K
There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride.

02:37Standard Enthalpy of Formation
49.0K
Enthalpy changes are typically tabulated for reactions in which both the reactants and products are at the same conditions. A standard state is a commonly accepted set of conditions used as a reference point for the determination of properties under other different conditions. For chemists, the IUPAC standard state refers to materials under a pressure of 1 bar and solutions at 1 M and does not specify a temperature. Many thermochemical tables list values with a standard state of 1 atm. Because...

03:45Formation of Complex Ions
25.8K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

01:23Microtubule Formation
7.5K
Microtubules are dynamic structures that undergo continuous assembly and disassembly. They originate from specialized multi-protein complexes known as microtubule organizing centers or MTOCs. Within the MTOC, the point of origin of the microtubule is known as the minus end, while the end radiating outward is the plus end. Microtubules serve two primary functions — the organization of spindle complexes to separate sister chromatids during mitotic or meiotic cell division and the formation...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
