Outcomes of Orthopaedic Surgery With and Without an External Femoral Derotational Osteotomy in @entity1 With XXXX .

@entity1 @entity2096 @entity26 @entity306
BACKGROUND: Ambulatory @entity1 with @entity306 ( @entity306 ) often present with multiple deviations in all planes including increased internal hip rotation during gait. @entity2096 is a common cause of deviation managed surgically with an external @entity2096 ( @entity2096 ). The purpose of this study was to evaluate the gait and functional outcomes of a group of subjects with @entity306 who underwent surgical intervention that included an @entity2096 compared with a match group with indications of internal hip rotation that did not receive an @entity2096 . METHODS: For this retrospective study, subjects were identified from the Motion Analysis Laboratory database that had orthopaedic surgery including an @entity2096 ( @entity2096 group). A control group was established from a chart review identifying subjects that had indications for an @entity2096 , but did not have this surgery (No- @entity2096 group). All subjects had preoperative and postoperative gait studies. Subjects categorized as Gross Motor Function Classification System (GMFCS) levels I and II in both @entity2096 and No- @entity2096 groups were combined for analysis. Subjects rated as GMFCS level III were analyzed separately. Preoperative to postoperative kinematic and kinetic variables, Gait Deviation Index, net @entity26 cost, and PODCI scores were analyzed with paired t tests. RESULTS: Typical sagittal plane kinematic variables improved significantly by equivalent magnitudes for both @entity2096 and No- @entity2096 groups (GMFCS I/II and III). Transverse plane improvements were only seen for the @entity2096 group (GMFCS I/II and III). The Gait Deviation Index, an overall index of kinematics, improved by a significantly greater amount for the @entity2096 group across GMFCS levels I/II and III. Net @entity26 cost improved for both @entity2096 and No- @entity2096 for GMFCS I/II. PODCI scores improved for @entity2096 and No- @entity2096 in GMFCS I/II, but only the @entity2096 group for GMFCS III. CONCLUSIONS: For @entity1 with @entity306 , inclusion of an @entity2096 in the surgical intervention, when indicated, resulted in improved outcomes. Overall gait kinematic improvements were significantly greater when an @entity2096 was included in the surgical management. LEVEL OF EVIDENCE: Level III-retrospective comparative study.
