RESUMO
PURPOSE: The ideal surgical management for tibial eminence avulsion fractures remains controversial with varying approach, methods of fixation and post-operative regimes reported throughout literature. The current systematic review and meta-analysis aims to compare between the different approaches, methods of fixation and post-operative regimes for tibial eminence fractures. METHODS: The systematic review was conducted according to PRISMA guidelines. A search was conducted using PubMed, MEDLINE and CINAHL databases. The keywords used were "anterior cruciate ligament", "tibial spine" or "tibial eminence" and "fracture" or "avulsion". All original human studies that reported the surgical outcomes of tibial eminence fractures were included. Individual patient data meta-analysis was performed. RESULTS: 48 studies with 1367 patients were included. Arthroscopic fixation resulted in significantly greater stability in terms of anterior drawer test (p = 0.018) and Lachman's test (p = 0.042), as compared to open fixation, though there was no significant difference for pivot shift test. There was no significant difference identified in functional scores and activity, including Lysholm score, IKDC subjective score, Tegner score and return to sports. Suture fixation had significantly increased stability compared to screw fixation, in terms of anterior drawer test (p = 0.001) and Lachman's test (p = 0.001), though no significant difference was identified for pivot shift test. Significantly better subjective scores and return to activity were also noted for suture fixation, in terms of Lysholm score (p = 0.008), IKDC subjective score (p = 0.001) and Tegner score (p = 0.001), though no significant difference was identified for return to sports. CONCLUSION: Arthroscopic and suture fixation had significantly superior outcomes when compared to open and screw fixation. Arthroscopic fixation resulted in significantly improved stability of the knee as compared to open fixation, though no significant difference was identified in terms of functional knee scores and return to activity. Suture fixation resulted in significantly improved stability of the knee and functional knee screws as compared to screw fixation.
RESUMO
PURPOSE: The current study aimed to evaluate the results of ultrasound screening for developmental dysplasia of the hips (DDH) done at various weeks of life, to determine the earliest time that ultrasound screening can be performed reliably. METHODS: In this 17-year cohort study, all neonates who underwent ultrasound screening prior to the 12th week of life with subsequent follow-up radiography done at 1 year of life were included. The ultrasound images were evaluated according to the Graf classification, Harcke’s dynamic ultrasound screening method, and Terjesen’s femoral head coverage method. The radiographic images were evaluated according to the acetabular index and the femoral head position. The accuracy and correlation between the ultrasound findings from various weeks of life with the radiographic findings at 1 year of life were evaluated. RESULTS: A total of 348 neonates were included in the study, of whom 92 had abnormal ultrasound findings and 42 had abnormal radiographic findings at 1 year. Significant differences were identified between the findings of ultrasound screening examinations performed prior to the fourth week of life (day 21 and before) and the radiographic findings at 1 year of life (P0.05). The accuracy of ultrasound screening was 79.2% or higher when performed during or after the fourth week of life (day 22 and beyond). CONCLUSION: The earliest that ultrasound screening for DDH can be performed reliably is during the fourth week of life (day 22 and beyond).
