Clinical Evaluation of Avascular Necrosis in Patients With Sickle Cell Disease: Children’s Hospital Oakland Hip Evaluation Scale—A Modification of the Harris Hip Score

Functional Outcomes in Children with Osteonecrosis Secondary to Treatment of Developmental Dysplasia of the Hip

“…We consider these differences to be clinically important. Aguilar et al reported a mean CHOHES score of 87.6 points for patients with a mean age of sixteen years and no hip problems 16 . In comparison, the overall mean CHOHES score for the patients in the present study (mean age, fourteen In the present study, we contrasted the different radiographic grades of femoral head osteonecrosis.…”

“…The CHOHES has been validated for patients with osteonecrosis of the hip secondary to sickle cell disease 16 . The CHOHES mean scores discriminated between patients with different grades of radiographic severity of osteonecrosis (p < 0.05) 16 . Patients with advanced radiographic features of osteonecrosis had significantly lower CHOHES mean scores.…”

“…The maximum score on the CHOHES is 100 points, indicating normal hip function. When administering the CHOHES, we adhered to the criteria described by Aguilar et al 16 . A single physiotherapist who was blinded to radiographic findings and medical history administered the CHOHES and performed all physical examinations.…”

What Clinimetric Evidence Exists for Using Hip-specific Patient-reported Outcome Measures in Pediatric Hip Impingement?

“…In adult FAI, evidence of some clinimetric evaluation was found for three PROs (HOS, NAHS, and WOMAC) in FAI populations [12]. Although it did not meet our inclusion criteria as part of the first search, we found one hip-and pediatricspecific PRO called the Children's Hospital Oakland Hip Evaluation Scale (CHOHES), which is a modification of the HHS [2]. It has been validated only in a population with avascular necrosis in sickle cell disease with a mean age of 25 years (range, 8-52 years) with no data on the effect of age presented [2].…”
