A scoping review of nutrition issues and management strategies in individuals with skeletal dysplasia

PURPOSE

Skeletal dysplasia are heterogeneous conditions affecting the skeleton. Common nutrition issues include feeding difficulties, obesity, and metabolic complications. This systematic scoping review aimed to identify key nutrition issues, management strategies, and gaps in knowledge regarding nutrition in skeletal dysplasia.

METHODS

The databases Ovid MEDLINE, Ovid EMBASE, Ebsco CINAHL, Scopus, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews were searched. Reference lists and citing literature for included studies were searched. Eligible studies included participants with skeletal dysplasia and described: anthropometry, body composition, nutrition-related biochemistry, clinical issues, dietary intake, measured energy or nutrition requirements, or nutrition interventions.

RESULTS

The literature search identified 8509 references from which 138 studies were included (130 observational, 3 intervention, 2 systematic reviews, and 3 clinical guidelines). Across 17 diagnoses identified, most studies described osteogenesis imperfecta (n = 50) and achondroplasia or hypochondroplasia (n = 47). Nutrition-related clinical issues, biochemistry, obesity, and metabolic complications were most commonly reported, and few studies measured energy requirements (n = 5).

CONCLUSION

Nutrition-related comorbidities are documented in skeletal dysplasia; yet, evidence to guide management is scarce. Evidence describing nutrition in rarer skeletal dysplasia conditions is lacking. Advances in skeletal dysplasia nutrition knowledge is needed to optimize broader health outcomes.

Treatment outcomes of hips in patients with epiphyseal dysplasia

Hip containment surgeries in multiple epiphyseal and spondyloepiphyseal dysplasia (MED/SED) patients aim to improve the mechanical environment of the hip joint. The purpose of this study was to determine if surgical intervention to improve femoral head coverage improved radiographic and clinical outcomes. A retrospective study identified patients with MED/SED seen in clinic between May 2000 and September 2017, with a minimum of 2-year follow-up. Patient charts/radiographs were reviewed for radiographic hip measurements, pain, and gait. Sixty-nine hips in 35 patients were identified. Forty-four hips were treated nonoperatively and 25 were treated surgically. The mean age at diagnosis was 6.2 years. The mean follow-up was 7.7 years for the surgical group and 7.1 years for the nonsurgical group. The mean postoperative follow-up was 5.4 years. Acetabular index decreased from initial to final visit by 9.0° in the surgical group and 1.6° in the nonsurgical group. Tonnis angle decreased by 13.5° in the surgical group and 1.5° in the nonsurgical group. Center edge angle increased by 19.0° in the surgical group and 7.1° in the nonsurgical group. Hips in the surgical group were 6.1 times more likely to experience an improvement in pain compared with hips in the nonsurgical group. Gait at the final follow-up was similar among the two groups. In this study cohort, containment surgery provided increased femoral head coverage; however, there was equal femoral head deformation despite intervention. Hips treated surgically were more likely to experience an improvement in pain; however, gait alterations did not improve.

Deformity correction in pediatric skeletal dysplasia: treatment challenges and solutions

We reviewed our experience with limb-deformity correction in 54 children with skeletal dysplasias. Our goal was to outline common treatment strategies developed in our hospital to overcome the challenges associated with the management of these conditions. Utilization of computer-assisted preoperative planning, intraoperative monitoring of peripheral nerve function, individualized bone segment stabilization using a modular circular external fixation system, and a flexible distraction protocol improved the precision of angular deformity correction in our practice, simplified external fixator assembly, diminished postoperative frame modifications, enhanced the stability of fixation, and reduced the rate of complications.

Measures of self-care independence for children with osteochondrodysplasia: a clinimetric review

This systematic review evaluates the validity, reliability, and clinical utility of outcome measures used to assess self-care skills among children with congenital musculoskeletal conditions and assesses the applicability of these measures for children with osteochondrodysplasia aged 0-12 years. Electronic databases were searched to identify self-care assessments that addressed the self-care domain as defined by of the International Classification of Function Disability and included children with osteochondrodysplasia. Ten measures were identified and three met the inclusion criteria: the Functional Independence Measure for Children (WeeFIM), the Activities Scale for Kids (ASK), and the Pediatric Evaluation of Disability Inventory (PEDI). Although psychometric data specific to children with osteochondrodysplasia are limited, adequate to excellent reliability and evidence of validity were reported for all three instruments for children with physical disabilities. Further evaluation of psychometric properties of self-care instruments specifically for children with osteochondrodysplasia would be beneficial to help identify instruments that will assist with improved assessment and management.

Bilateral total hip arthroplasty in subjects with multiple epiphyseal dysplasia

Multiple epiphyseal dysplasia (MED) is a rare autosomal dominant skeletal dysplasia caused by abnormalities in the gene(s) coding for type IX collagen and cartilage oligomeric matrix protein. Clinically, the disease is characterized by abnormalities in the epiphyseal cartilage of multiple joints. Orthopedic manifestations include pain and restricted mobility. The disorder, which has a predilection for the femoral head and acetabulum, usually presents from the third to the fourth decade with secondary hip osteoarthritis. We report on 7 subjects affected by multiple epiphyseal dysplasia, which presented hip osteoarthritis in their third decade of life and underwent staged bilateral total hip arthroplasty. All patients experienced pain relief and improved quality of life after surgical treatment.

Spondyloepiphyseal dysplasia tarda: four cases from two families

Spondyloepiphyseal dysplasia tarda with progressive arthropathy (SEDT-PA) is an autosomal recessively inherited skeletal dysplasia. We present four patients (three patients-a brother and a sister and their third cousin-in a family and one patient in another family) with SEDT-PA. All patients had short stature and stubby hands and feet. Their radiographs revealed typical changes for SEDT-PA including platyspondyly, severe osteopenia and dysplastic bone changes. Physical therapy and exercises were performed to all patients in order to decrease in pain and increase or at least maintain joint motion and mobility. Symptomatic relief was achieved in all patients for about a couple of months. The major clinical importance of this rather rare disorder is its similarity to juvenile idiopathic arthritis which has rather different treatment protocol.
