Objective:
To compare 2 distraction osteogenesis techniques in post-traumatic tibial nonunion patients with composite bone and soft-tissue defects.
Design:
Nonrandomized prospective, case series, single-center study.
Setting:
Department of Orthopaedics and Traumatology, Limb Reconstruction Unit, El-Helal hospital, Cairo, Egypt.
Participants:
Fifty post-traumatic tibial nonunion patients with composite bone and soft-tissue defects.
Intervention:
Twenty-five patients were treated using bone transport (BT) technique, and 25 patients were treated using acute shortening (AS) and distraction technique.
Outcome Measurements:
The external fixation index (EFI); functional and bone results; and complication rates.
Results:
All patients were followed for a minimum of 18 months after removal of their Ilizarov frame. AS and BT groups were followed up for a mean of 19.7 and 20.3 months, respectively. The mean bone gap after resection and debridement was 4 cm in AS group and 5.9 cm in BT group (P = 0.06). The mean EFI was statistically significant and lower in the AS group compared with BT group (P = 0.03). There were no other statistically significant differences between either intervention groups.
Conclusions:
Both techniques achieved comparable good to excellent results, and the differences in number of complications and ASAMI scores for bone or function were not statistically significant. Yet, it appears that the AS technique may be superior because it has a significantly lower EFI. This may not be feasible in all cases, however, because the AS technique is limited by the defect size and the condition of the surrounding soft tissues.

Purpose Surgical treatment in advanced-stage infantile Blount’s disease with medial plateau (MP) depression is challenging. Several osteotomies and fixation methods have been described with no established benchmark. We conducted this study to evaluate the efficacy and safety of a new single-stage technique for acute medial condyle elevation and metaphyseal osteotomies with internal fixation. Methods A prospective case series of 19 consecutive patients (21 knees) with severe infantile Blount’s disease underwent a single-stage MP elevation and metaphyseal osteotomies, with internal fixation. The mean age was 10.3 years (8.2 to 13.6) and the mean follow-up was 5.1 years (3.2 to 8.3). The outcome measures included clinical and radiological parameters and patient-reported pediatric outcomes data collection instrument (PODCI) score. Results The mean PODCI score improved significantly from 50% to 88%. The mean internal tibial torsion improved from -27° to 11°. All cases maintained full knee extension, no limitation in flexion range of movement and no signs of instability or lateral thrust gait. All the radiographic parameters improved significantly; the mean tibiofemoral angle improved from -29° to 7°, the metaphyseal-diaphyseal angle improved from 33.4° to 4.7° and the angle of depressed MP improved from 38.3° to 2.4° (p < 0.001). At the latest follow-up, no cases of deformity recurrence were identified, the final limb-length discrepancy was < 1 cm in all patients. Conclusion Single-stage MP elevation and metaphyseal osteotomies with internal fixation significantly improved the clinical and radiographic parameters and PODCI score in advanced infantile Blount’s disease and precluded the use of external immobilization, with no evidence of deformity recurrence.

Hip dislocation is a common source of disability in cerebral palsy children. It has been remedied by various reconstructive procedures. This review aims at providing the best evidence for bony reconstructive procedures in cerebral palsy hip migration. The literature extraction process yielded 36 articles for inclusion in this review. There is fair evidence to indicate that the comparative effectiveness of femoral versus combined pelvifemoral reconstruction favours pelvifemoral reconstruction. All except one were retrospective articles with a significant degree of selection and performance bias and confounding variables that limited the validity and generalizability of the conclusions. The findings of this systematic review provide fair evidence for the use of adequate soft tissue and combined pelvifemoral reconstruction in the management of hip migration in none and minimally ambulatory cerebral palsy children in the short and long term. This has been shown in studies with a summed sizable patient population. There is limited evidence available that would support the use of soft-tissue and isolated femoral reconstruction. In the context of these retrospective and biased studies, it is extremely difficult to identify, with great precision, predictors of surgical success. Future studies should consider prospective designs that allow for bias control, strict patient selection criteria and incorporation of validated quality-of-life scales.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
