NCT07095244

Brief Summary

Varus-derotation osteotomy (VDRO) is a surgery to prevent or address hip displacement in children. Many children having this surgery have cerebral palsy or other neuromotor disorders, who have a higher rate of malnutrition, including low iron or anemia. This can affect their surgical outcomes, such as increasing their need for blood transfusions. This project aims to develop a preoperative nutritional program for VDRO patients, to improve their surgical outcomes and decrease their need for transfusions. This may include taking iron supplementation for patient with low iron or anemia. Participants will undergo a nutrition program before their surgery.

Outcome Measures

Primary Outcomes (1)

  • Decreased incidence of blood transfusion

    A comprehensive nutritional prehabilitation intervention for iron deficiency anemia before pediatric VDRO surgery will decrease the risk of requiring a blood transfusion, as shown by a decreased incidence of blood transfusions, in the perioperative period.

    From surgery start time to discharge from hospital.

Secondary Outcomes (4)

  • Resolution of anemia

    From baseline to 12 months post-op.

  • Increased Iron Levels

    From baseline to 12 months post-op.

  • Lower incidence of surgical site infection and pressure wounds

    From the day of surgery to 30 days post-op.

  • Decreased hospital length of stay

    From the date of surgery until the date of hospital discharge.

Study Arms (3)

Prospective (Iron Supplementation)

EXPERIMENTAL

Patients scheduled for VDRO and/or pelvic osteotomy surgery who are aged 0 to 18 years old (n = 50-60). Note that the investigators will include patients who do or do not have a diagnosis of a neuromotor condition. All patients will be evaluated by the dietitian and have screening lab work to evaluate for iron deficiency at initial consultation. If lab results show that iron supplementation is required, patients will be allocated to the iron supplementation arm and will receive a prescription for iron supplementation, education on non-pharmacological methods to enhance iron intake and comprehensive nutrition management.

Dietary Supplement: Iron SupplementDietary Supplement: Comprehensive Nutrition Management

Historical

NO INTERVENTION

All patients who had VDRO and/or pelvic osteotomy surgery between February 2022 and December 2024 who are aged 0 to 18 years old (n = 100-120). These participants will be enrolled as comparators and receive no intervention, as their surgery has passed.

Prospective (No Iron Supplementation)

EXPERIMENTAL

Patients scheduled for VDRO and/or pelvic osteotomy surgery who are aged 0 to 18 years old (n = 50-60). Note that the investigators will include patients who do or do not have a diagnosis of a neuromotor condition. All patients will be evaluated by the dietitian and have screening lab work to evaluate for iron deficiency at initial consultation. If lab results show adequate iron levels, patients will be allocated to the "no iron supplementation" arm and will only receive comprehensive nutrition management, without an iron supplementation prescription.

Dietary Supplement: Comprehensive Nutrition Management

Interventions

Standard nutrition care will depend on the results of the nutrition assessment, as well as underlying conditions, and will be performed regardless of iron supplementation. The intervention will be at the discretion of the dietician but may include; diet education, recommendations for vitamin and mineral supplements, optimization of tube feeds (if the child is tube fed), high protein or high energy diet education if the child is underweight, dddition of oral nutrition supplements (i.e., Pediasure or Ensure) to promote weight gain in orally fed children, discussion surrounding enteral feeding (for children who are orally fed, but severely malnourished and cannot meet their nutritional needs by mouth).

Eligibility Criteria

Age0 Years - 18 Years

Model Details: All participants who are enrolled prospectively will receive comprehensive nutrition management, which includes a blood test. Participants will have their blood work done prior to initiating nutrition intervention for iron-deficiency (two tubes containing 1 to 2 ml each). If patients are determined to be iron-deficient or anemic, they will be prescribed iron supplementation. All patients will receive comprehensive nutrition management from a clinical dietician during the months leading up to their procedure (up to 12 months preoperatively). Patients will have their blood re-tested in the operating room before surgery (after the induction of anesthesia).
