Summary
Hallux valgus surgery, specifically distal Chevron and Akin osteotomies, can effectively reduce forefoot width. Metatarsal span (MS) reduction is a reliable radiographic indicator of successful hallux valgus correction.
Area of Science:
- Orthopedic Surgery
- Radiology
- Foot and Ankle Surgery
Background:
- Hallux valgus is often characterized by forefoot widening.
- Surgical correction of hallux valgus may reduce forefoot width.
- Reduced forefoot width (metatarsal span) may correlate with improved pain relief and foot appearance after surgery.
Purpose of the Study:
- To evaluate the reliability of metatarsal span (MS) as a radiographic indicator of hallux valgus surgical success.
- To assess the potential of distal Chevron and Akin osteotomies to reduce forefoot width.
Main Methods:
- Preoperative and postoperative radiographs of 52 hallux valgus patients were analyzed.
- Measurements included hallux valgus angle (HVA), intermetatarsal angle (IMA), and metatarsal span (MS).
- Four observers performed digital radiographic linear measurements.
Main Results:
- The distal Chevron and Akin osteotomy procedure resulted in an average MS reduction of 8.7 mm.
- Average improvements were noted in HVA (19.4°) and IMA (6.7°).
- No significant correlation was found between HVA or IMA correction and MS reduction.
Conclusions:
- Digital radiographic linear measurements for MS are reliable and easy to perform.
- Metatarsal span reduction is a potential radiographic tool to evaluate clinical outcomes in hallux valgus surgery.
- Distal Chevron with Akin osteotomy can reduce forefoot width.

01:15Distance Corrections
285
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

01:20Power Factor Correction
515
The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

01:18Reducing Line Loss
372
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

01:14NMR Spectrometers: Resolution and Error Correction
1.0K
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

28.0K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
