Introduction The role of proximal femur morphology to the development of certain proximal femur fracture types both femoral neck and trochanteric fractures has been observed. However, the relavance of acetabular morphology to the development of proximal femur fractures is not extensively questioned. Therefore the aim of the study was to determine whether there is a correlation between acetabular morphology and pathogenesis of 2 different hip fracture types after low energy trauma. Methods This retrospective study includes 60 cases (41 women, 19 men) with a proximal femoral fracture after a low energy trauma between July 2012 and December 2014. Acetabular depth and acetabular index were measured on pelvic radiographs. Neck shaft angle, hip axis length and cortical index were measured on pelvic computed tomography scans. All measurements were performed on the contralateral hip. Results Mean age was 77.56 ± 8.99 years (range 61-92 years). No statistically significant difference was found with regard to neck shaft angle, acetabular depth or cortical index measurements between patients with femoral neck fracture and patients with trochanteric femoral fractures (p>0.05). Acetabular index measurement was higher (p = 0.001) and hip axis length measurement was lower (p = 0.001) in trochanteric fracture group as compared to femoral neck fracture. Conclusions The rate of trochanteric femur fractures is higher in patients with high acetabular index, whereas the rate of femoral neck fractures is higher in patients with increased hip axis length.

Objective: To use the measurement of migration percentage (MP) to evaluate the long-term radiographic results of soft tissue surgery as the first treatment for hip displacement in spastic bilateral cerebral palsy. A secondary objective was to identify predictive factors of stability (i.e., less than 30% of MP in the long term), after surgical correction. Methods: In this longitudinal cohort study, we reviewed the electronic medical records and radiographs of all consecutive patients with cerebral palsy operated for the correction of hip displacement between 1984 and 2013 in a referral orthopedic public hospital in Brazil. Patients were included if they had received, as the first surgical procedure, soft-tissue release. All surgeries were bilateral and symmetrical. We used the available radiographs to evaluate the migration percentage (MP), acetabular index (AI), pelvic obliquity (PO) angle, head-shaft angle (HSA), congruence and femoral head sphericity, and function using the GMFCS (Gross Motor Function Classification System). Results: we included 93 patients, all operated before being 12 years old, with follow-up of 10 years in average, 73 (78%) of them with good results (MP < 30%). We found association between preoperative MP ≤ 40%, AI ≤ 25°, and postoperative symmetry with good results, with a cut-off value of 38% of MP and 27° of acetabular index being predictive. Discussion: The role of soft tissue releases remains controversial owing to small sample sizes, heterogeneity, variety range of ages, definitions used for outcome, and lack of statistical quality. Our results were better in combined tenotomies, in diparetic patients aged more than six years, and in patients with lower initial values of MP and AI. Radiographic variables had good correlation with each other and association with results, with cut-off values for MP and AI PRE.

Purpose The correlation between the degree of developmental hip dysplasia (DDH) measured on ultrasound images compared with that measured on radiographs is not clear. Most studies have compared ultrasonography (US) and radiographic images made at different times of follow-up. In this study the correlation between US images and radiographs of the hip made on the same day was evaluated. Methods US images and radiographs of both hips of 74 infants, who were treated for stable DDH, were reviewed in a retrospective study. Only infants who had an US examination and a radiograph on the same day were included. Results The correlation between α-angle of Graf and femoral head coverage on US was strong (p ≤ 0.0001). Weak correlations were found between the acetabular index of Tönnis on radiographs and α-angle of Graf on US (p = 0.049) and between acetabular index of Tönnis on radiographs and femoral head coverage of Morin on US (p = 0.100). Conclusion This study reports on the correlation between US and radiographic imaging outcomes, both made on the same day in patients for treatment and follow-up of DDH. Level of Evidence IV

Introduction. Hip dysplasia in infants is one of the most common congenital defects of connective tissue. It is assumed that correction of somatic dysfunctions, which are formed in this orthopaedic pathology, will affect the timing of treatment and rehabilitation.Goal of research — to explore the opportunities of osteopathic correction for somatic dysfunctions in comprehensive conservative treatment of hip joint congenital orthopaedic pathology in young infants.Materials and methods. There were 40 infants under 6 month with diagnosis of hip joint dysplasia under observation, divided into two groups of 20 infants each. Functional orthopaedic treatment (massage, physiotherapy, exercise therapy, orthopaedic splint) and osteopathic correction were performed for infants of the main group. Infants of the control group received the orthopaedic treatment only. Osteopathic status was rated in addition to provided treatment in both groups. Treatment results were evaluated by using hip joints radiography, namely, by the acetabular index.Results. It was found that global somatic dysfunctions are not typical in infants with hip joint congenital defects. The most frequently identifi ed somatic dysfunctions were regional, in a region of head, neck, pelvis, as well as thoracic region. Somatic dysfunctions of head and pelvis region are the most signifi cant. It proves the functional connection between these dysfunctions and hip joint congenital defexts. X-ray examination data analysis let us suggest a direct effect of somatic dysfunctions correction on the acetabular index in infants with congenital orthopaedic pathology, and thus on rehabilitation periods reduction.Conclusion. The study showed that osteopathic correction of somatic dysfunctions is effective in combination with orthopaedic treatment of hip dysplasia performed from the fi rst months of infant′s life. It should be recommended as a part of comprehensive therapy of this orthopaedic pathology.
