Summary
Isolated greater trochanter fractures weaken hip abducent strength, potentially due to associated muscle and ligament damage. Further research into surgical techniques for these fractures is recommended.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Biomechanics
Background:
- Isolated greater trochanter fractures are rare femoral injuries.
- These fractures can impact hip abducent muscles (gluteus medius and minimus) and cause chronic pain.
- The effect of these fractures on abducent strength and hip function remains understudied.
Purpose of the Study:
- To investigate the impact of isolated greater trochanter fractures on hip abducent strength and function.
- To compare hip function and strength between injured and healthy sides.
Main Methods:
- Retrospective study of 32 patients with greater trochanter fractures treated conservatively.
- Diagnosis confirmed via CT scans and X-rays, with MRI for occult fractures.
- Assessment of Harris Hip Score, abducent strength, and range of motion at 3, 6, and 12 months.
Main Results:
- Of 32 patients, 7 had isolated fractures; 25 had extended intertrochanteric fractures.
- After 12 months, 7 patients reported persistent hip pain.
- Abducent strength was significantly lower on the injured side (121.32 N) compared to the healthy side (137.44 N).
Conclusions:
- Isolated greater trochanter fractures lead to reduced hip abducent strength.
- This reduction may stem from associated ligament and muscle injuries.
- Surgical management strategies for these fractures require further investigation.

01:24Role of Affect in Interpersonal Attraction
219
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

01:29The Influence of Affect on Cognition
277
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

01:29The Influence of Cognition on Affect
200
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

01:20Strength of Cement
488
Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

01:30Relation Between Tensile Strength and Compressive Strength of Concrete
666
Concrete is a fundamental building material, and understanding its strengths is crucial for construction projects. The relationship between its tensile and compressive strengths is intricate, showing that while these strengths are related, they do not increase at the same rate. Tensile strength's growth is slower and is affected by various factors such as the methods used for testing, the size and shape of the specimen, the texture of the aggregate used, and the moisture content of the...
