Anterior minimally invasive subcapital osteotomy without Hip Dislocation for slipped capital femoral epiphysis
International Orthopaedics, 2016Co-Authors: Cesare Faldini, Marcello De Fine, Alberto Di Martino, Daniele Fabbri, Raffele Borghi, Camilla Pungetti, Francesco TrainaAbstract:Purpose A minimally invasive anterior approach appears to be an attractive alternative to achieve capital realignment without violating femoral head vascular supply and avoiding Hip Dislocation in slipped capital femoral epiphysis. The aim of this study was to detail the technical steps of subcapital realignment through a minimally invasive anterior approach and to report the preliminary results of this procedure in a prospective cohort of patients with stable slips. Methods Nine patients underwent subcapital cuneiform wedge resection through a minimally invasive anterior approach without Hip Dislocation for moderate or severe stable slips between April 2012 and April 2013. Prophylactic stabilization of the contralateral Hip was performed in all cases. A minimum 18 months follow-up was available. Clinical course was assessed using the Harris Hip score and the Hip range of motion. The degree of slippage as proposed by Southwick, the lateral α angle and the epiphyseal-metaphyseal distance allowed radiographic assessment. Results No patients were lost during follow-up, which was on average 28 months. No intraoperative complications occurred; one postoperative transient apraxia of the femoral cutaneous nerve, which completely recovered in six months, was recorded. Southwick angle, lateral α angle and epiphyseal-metaphyseal distance all improved substantially postoperatively. No cases of avascular necrosis were detected. Conclusion Subcapital cuneiform wedge resection through a minimally invasive anterior approach without Hip Dislocation can be an easier alternative to restore proximal femoral anatomy in moderate to severe stable slips. Prospective case control studies are required to confirm these preliminary results.

recurrent Hip Dislocation following total Hip arthroplasty treatment with sagittal spinal deformity correction
Journal of Bone and Joint Surgery American Volume, 2017Co-Authors: Yoonje Cho, Junghee Lee, Sung Joon Shin, Kyungchung KangAbstract:Case: A 63-year-old woman with lumbar degenerative kyphosis who had undergone total Hip arthroplasty 34 months previously presented after having multiple episodes of anterior Hip Dislocation; evaluation also revealed progressive osteoarthritis in the contralateral Hip joint. The patient was managed with sagittal correction with pedicle subtraction osteotomy, which resulted in optimal positioning of the acetabular component and an upright posture. The patient had had no additional Dislocation events in the involved Hip and had reduced pain in the contralateral Hip at the time of the 2-year follow-up. Conclusion: It is important to evaluate and address preexisting sagittal imbalance before performing total Hip arthroplasty. However, for patients with neglected sagittal imbalance resulting in recurrent Hip Dislocation after total Hip arthroplasty, sagittal deformity correction may be beneficial.

femoroacetabular impingement predisposes to traumatic posterior Hip Dislocation
Clinical Orthopaedics and Related Research, 2013Co-Authors: Simon Steppacher, Moritz Tannast, Klaus Siebenrock, Christoph E Albers, Reinhold GanzAbstract:Background Traumatic posterior Hip Dislocation in adults is generally understood to be the result of a high-energy trauma. Aside from reduced femoral antetorsion, morphologic risk factors for Dislocation are unknown. We previously noticed that some Hips with traumatic posterior Dislocations had evidence of morphologic features of femoroacetabular impingement (FAI), therefore, we sought to evaluate that possibility more formally.

ACETABULAR RETROVERSION AS A CONTRIBUTING FACTOR FOR POSTERIOR TRAUMATIC Hip Dislocation
2012Co-Authors: Simon Steppacher, Christoph Albers, Moritz Tannast, Klaus Siebenrock, Reinhold GanzAbstract:Traumatic Hip Dislocation is a rare injury in orthopaedic practice and typically occures in high energy trauma. The goal of this study was to analyze Hip morphology in patients with low energy traumatic Hip Dislocations and to compare it with a control group. We performed a retrospective comparative study. The study group included 45 patients with 45 traumatic posterior Hip Dislocation. Inclusion criteria were traumatic Hip Dislocation with simple acetabular rim or Pipkin I or II fracture. Traumatic Dislocations combined with other acetabular or femoral fractures were excluded. The control group consisted of 90 patients (180 Hips) that underwent radiographic examination for urogenital indication and had no history of Hip pain. Hip morphology was assessed on antero-posterior and axial views. The study group showed significantly increased incidence (p Hips that underwent an low energy posterior traumatic Hip Dislocation show significanly more radiographic signs for acetabular retroversion compared to a control group. Therefore, acetabular retroversion seems to be a contributing factor for posterior traumatic Hip Dislocation.

midterm results of surgical Hip Dislocation for the treatment of femoroacetabular impingement
American Journal of Sports Medicine, 2012Co-Authors: Florian D Naal, Hermes Howard Miozzari, Michael Schar, Tobias Hesper, Hubert P NotzliAbstract:Background:Surgical treatment of femoroacetabular impingement (FAI) includes both open and arthroscopic procedures. Encouraging results have been reported for the majority of patients after surgical Hip Dislocation; however, most of these reports were short term and included only small cohorts.Purpose:To determine the results of surgical Hip Dislocation in a large cohort of FAI patients at a midterm follow-up.Study Design:Case series; Level of evidence, 4.Methods:A retrospective study including 185 consecutive patients (mean age, 30 years; 40% female) with 233 Hips treated was conducted. We determined clinical outcomes in terms of range of motion and analyzed radiographs for several criteria including the alpha angle preoperatively and at 1 year postoperatively. At latest follow-up, on average 61 months postoperatively, patient satisfaction, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Hip Outcome Score, SF-12, and University of California, Los Angeles (UCLA) activity scale ...

surgical Hip Dislocation for the treatment of femoroacetabular impingement in high level athletes
American Journal of Sports Medicine, 2011Co-Authors: Florian D Naal, Hermes Howard Miozzari, Tobias F Wyss, Hubert P NotzliAbstract:Background: Midterm outcome studies show that symptomatic femoroacetabular impingement (FAI) can be successfully treated by addressing the underlying pathomorphology with open or arthroscopic surgery. Although athletes may be vulnerable to Hip injury from impingement, limited information is available regarding the results of open surgery in this group.Hypothesis: High-level athletes with FAI can resume their sports after surgical Hip Dislocation and continue professional careers for a significant period.Study Design: Case series; Level of evidence, 4.Methods: Twenty-two professional male athletes (19.7 ± 2.2 years) were evaluated by postal survey at a mean of 45.1 months (range, 12 to 79) after treatment by surgical Hip Dislocation (30 Hips, cam- or mixed-type FAI; mean α angle, 69.3°; 14 ice hockey players). Evaluation included types and level of sports, subjective ratings, and clinical outcomes: Hip Outcome Score, SF-12, UCLA (University of California, Los Angeles) activity scale, Hip Sports Activity Sc...
