Summary
A modified proximal scarf osteotomy effectively treats hallux valgus, showing significant improvements in deformity angles and patient satisfaction. This technique offers comparable results to the classic method for moderate to severe cases.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Surgery
- Skeletal Biomechanics
Background:
- Hallux valgus is a common foot deformity requiring surgical correction.
- The proximal scarf osteotomy is a recognized technique for hallux valgus repair.
- A modified technique was developed to potentially improve correction of moderate to severe hallux valgus.
Purpose of the Study:
- To evaluate the clinical and radiographic outcomes of a modified proximal scarf osteotomy.
- To compare the modified technique with the classic scarf osteotomy for hallux valgus treatment.
- To assess the efficacy of the modified technique in correcting moderate to severe hallux valgus deformities.
Main Methods:
- A modified proximal scarf osteotomy was performed on 35 patients (44 cases) with moderate hallux valgus.
- Clinical outcomes were assessed using the American Orthopedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS).
- Radiographic measurements included hallux valgus angle, first intermetatarsal angle, and distal metatarsal articular angle.
Main Results:
- Significant improvements were observed in hallux valgus angle (32.2° to 12.5°), first intermetatarsal angle (14.3° to 8.6°), and distal metatarsal articular angle (18.7° to 12.4°).
- Mean AOFAS scores improved from 47 to 86, and VAS scores decreased from 7 to 1.
- No significant change in the height of the first metatarsal-cuneiform joint was noted; limited range of motion occurred in two cases.
Conclusions:
- The modified proximal scarf osteotomy yields comparable results to the classic technique regarding first intermetatarsal angle correction and patient satisfaction.
- The modified technique is a viable option for treating moderate to severe hallux valgus.
- Further consideration of this modified osteotomy is recommended alongside other proximal osteotomy techniques.

01:22Factors Influencing Attraction I: Proximity
268
Proximity plays a fundamental role in shaping interpersonal attraction by increasing opportunities for interaction and fostering familiarity. Research consistently demonstrates that individuals are more likely to form social bonds with those who are physically closer to them, whether in residential settings, workplaces, or educational institutions. This effect is largely driven by the increased frequency of encounters, which facilitates the development of friendships and romantic...

A standard box and whisker plot informs us about the spread of the data in a given sample. One can identify the minimum value, maximum value, first quartile value, second quartile or median value, and third quartile.
However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.
Initially, we calculate the adjusted...

1.8K
Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.

02:09Operons
54.3K
Prokaryotes can control gene expression through operons—DNA sequences consisting of regulatory elements and clustered, functionally related protein-coding genes. Operons use a single promoter sequence to initiate transcription of a gene cluster (i.e., a group of structural genes) into a single mRNA molecule. The terminator sequence ends transcription. An operator sequence, located between the promoter and structural genes, prohibits the operon’s transcriptional activity if bound by...

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,...

02:53Ribosomal RNA Synthesis
14.8K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
