Summary
This study shows that a mobility-preserving surgery using a temporary metal spacer for hallux rigidus (stiff big toe) provides good to excellent results, improving patient scores and range of motion.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Surgery
- Podiatric Medicine
Background:
- Hallux rigidus, grades II-III, often requires surgical intervention when conservative treatments fail.
- Mobility-preserving techniques are sought to improve outcomes for hallux rigidus patients.
Purpose of the Study:
- To evaluate the efficacy of a mobility-preserving surgical technique for hallux rigidus.
- To assess outcomes of resection arthroplasty with a temporary metal spacer for grades II-III hallux rigidus.
Main Methods:
- Prospective study of 30 patients (18 female, 12 male) with grade II-III hallux rigidus.
- Minimal resection arthroplasty with a temporary metal spacer, followed by spacer removal at 6 months.
- Clinical and radiographic evaluation at 3, 6, 12 months, and 5 years post-removal.
Main Results:
- Significant improvement in American Orthopaedic Foot and Ankle Society (AOFAS) scores observed up to the first year.
- Marked decrease in severely limited range of motion (ROM) at 3, 6, and 12 months.
- Two minor, self-resolving complications with no impact on procedure effectiveness.
Conclusions:
- The mobility-preserving technique using a temporary metal spacer yields good to excellent results for symptomatic hallux rigidus (grades II-III).
- This novel procedure is straightforward to perform and cost-effective.

52.1K
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

02:37Metallic Solids
20.5K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

24.2K
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

02:58Properties of Transition Metals
29.6K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

The contact of metal and semiconductor can lead to the formation of a junction with either Schottky or Ohmic behavior.
Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...
