Effect of Calcium β-Hydroxy-β-Methylbutyrate (CaHMB), Vitamin D, and Protein Supplementation on Postoperative Immobilization in Malnourished Older Adult Patients With Hip Fracture: A Randomized Controlled Study.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Nutrition support in orthopedic patients with malnutrition shortens the immobilization period.

The researchers investigated the effects of CaHMB, vitamin D, and protein supplementation on wound healing, immobilization period, muscle strength, and laboratory parameters.

Who Took Part

According to the abstract, 75 patients were involved.

PubMed indexes the participants as older adults and people over 80, women only.

This randomized controlled study included 75 older female patients with a hip fracture admitted to orthopedic clinics.

Anthropometric, laboratory, wound-healing, immobilization period, and muscle strength assessments were evaluated preoperatively and on postoperative days 15 and 30.

How the Study Was Run

The researchers set it up as a randomized study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The control group received standard postoperative nutrition.

What Was Measured

The subject headings attached to it are Calcium, Dietary Proteins, Dietary Supplements, Hip Fractures, Nutritional Support, Valerates and Vitamin D.

The authors tagged it with the keywords aged, hydroxy-methylbutyrate and malnutrition.

What This Means in Plain Language

The paper is a randomized study of Vitamin D, K2, Magnesium and Zinc in 75 patients.
