Summary
Developmental dysplasia of the hip (DDH) screening methods show similar outcomes for severe cases, despite varying practices. Current policies reflect resource availability more than definitive evidence.
Area of Science:
- Orthopedics
- Pediatrics
- Public Health
Background:
- Developmental dysplasia of the hip (DDH) screening is standard for newborns, but practices vary globally.
- Controversies exist regarding the effectiveness of different screening strategies.
Purpose of the Study:
- To review screening controversies for DDH.
- To explore why various screening programs yield similar outcomes.
- To discuss factors influencing DDH development.
Main Methods:
- Narrative mini-review of existing literature on DDH screening.
- Discussion of different screening strategies (universal ultrasound, selective ultrasound, clinical examination).
- Analysis of extrinsic factors affecting hip development post-birth.
Main Results:
- Universal ultrasound (US) detects more immature hips but doesn't reduce late-detected DDH or surgical rates.
- Selective US and clinical screening show similar late detection rates compared to universal US.
- Post-natal extrinsic factors can influence hip development, impacting early screening accuracy.
Conclusions:
- DDH screening strategies have limitations, with no significant differences in severe outcomes (late-detected, operative cases).
- Screening policy decisions are influenced by resource availability and societal values, not solely by clear evidence.
- Acknowledging these limitations is crucial for policy development.

01:29Life Histories
Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.
02:20Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
01:50Cross-Sectional Research
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
02:01Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
01:52Regression Toward the Mean
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
