minimally invasive surgery of hip

Sajad Arabnejad, Burnett Johnston, Michael Tanzer, Damiano Pasini
Current hip replacement femoral implants are made of fully solid materials which all have stiffness considerably higher than that of bone. This mechanical mismatch can cause significant bone resorption secondary to stress shielding, which can lead to serious complications such as peri-prosthetic fracture during or after revision surgery. In this work, a high strength fully porous material with tunable mechanical properties is introduced for use in hip replacement design. The implant macro geometry is based off of a short stem taper-wedge implant compatible with minimally invasive hip replacement surgery...

Recent advances in hip arthroscopy offer an approach for treating an uncommon but highly disabling injury from intra-articular missile injury to the hip. Hip arthroscopy affords the patient the benefit of minimally invasive surgery while allowing for the diagnosis and treatment of concomitant pathology, which may be either acute, from the trauma of the missile, or chronic. We present a technique for the removal of projectiles from the central and peripheral compartments of the hip joint. Through a surgical series of a variety of gunshot wounds, we detail the unique aspects of retrieval for the various missile endpoints...

BACKGROUND: Sacroiliac joint (SIJ) fusion (SIJF), first performed 95 years ago, has become an increasingly accepted surgical option for chronic SIJ dysfunction. Few studies have reported intermediate- or long-term outcomes after SIJF. OBJECTIVE: The objective of this study is to determine patient-based outcomes after SIJF for chronic SIJ dysfunction due to degenerative sacroiliitis or SIJ disruption at ≥3 years of follow-up. METHODS: Consecutive patients who underwent SIJF prior to December 2012 were contacted over phone or through email...

BACKGROUND: In recent years, hip arthroscopy has rapidly evolved, offering patients evidence-based interventions with the merits of minimally invasive surgery and a relatively short rehabilitation period. Although considered a safe procedure, hip arthroscopy has associated complications that may be underreported depending on how patients are asked about their complications. PURPOSE: The aim of this study was to evaluate hip arthroscopy complications from the patient's perspective...

This article is concerned with the search for threshold values for bone quality beyond which the risk of fixation failure increased. For trochanteric fractures we recognized a BMD lower than 250mg/cm(3) as an additional risk for cut out. For medial femoral neck fractures since joint replacement surgery is available and produces excellent functional results, we see no indication for further differentiation or analysis of bone quality in relation to fracture fixation. In the area of osteoporotic vertebral body fractures, there are many experimental studies that try to identify BMD limits of screw fixation in the cancellous bone on the basis of QCT analysis...

PURPOSE: The direct anterior approach is an attractive option for total hip arthroplasty (THA) in order to achieve a quicker rehabilitation. However, this surgical technique presents a longer learning curve and a higher complications rate compared with the standard approach. We investigated whether three-dimensional (3D) planning anticipated the surgical difficulties and helped to achieve a low complications rate with respect to intra-operative complications, dislocation risk and lower limb discrepancy (LLD)...

INTRODUCTION: There is renewed interest in total hip arthroplasty (THA) with the development of minimally invasive approaches. The anterior and Röttinger approaches are attractive for their anatomical and minimally invasive character, but with no comparative studies in the literature definitely suggesting superiority in terms of quality of functional recovery. We therefore performed a case-control study, assessing: 1) whether the postural parameters of patients operated on with the anterior, Röttinger and posterior minimally invasive approaches were similar to those of asymptomatic subjects, and 2) whether there were any differences in postural parameters between the three approaches at short-term follow-up...

PURPOSE: Hip intertrochanteric fractures are very frequent. Early mobilization reduces the associated mortality and morbidity rate. DHS is still commonly used in many centers. We describe a new minimal invasive DHS technique (MIDHS) depending on radiological land marks, facilitating the application of DHS in a proper way without the use of an angle guide and we retrospectively compared the functional results of the new technique with that of the conventional DHS (CDHS) technique. METHODS: 116 patients (MIDHS n = 56; CDHS n = 60) with stable intertrochanteric fractures were followed up for at least 12 months...

BACKGROUND: With the evolution of total hip joint replacement techniques, there has been a trend towards minimally invasive surgery. The anterior approach (AA) to total hip arthroplasty has been widely associated with less soft tissue damage. The aim of our study was to compare clinical and 1-year functional outcomes for AA hip arthroplasty versus a posterior approach (PA). METHOD: We retrospectively reviewed 92 (50 anterior and 42 posterior) total hip replacements performed at our centre between 2006 and 2011...

For decades, the average hospital stay following total joint arthroplasty (TJA) has been getting shorter. The historical standard was several weeks of hospitalization, yet improvements in perioperative care have reduced the average length of stay to a few days. Medicare recognizes a 3-day inpatient stay as the standard of care following hip or knee replacement. Yet continued advances in minimally invasive surgical techniques, short-acting general anesthetics, long-acting local anesthetics, and blood loss management have further improved the safety and recovery for TJA procedures...

PURPOSE: Minimal invasive techniques in total hip arthroplasty (THA) have become increasingly popular during recent years. Despite much debate over the outcome of several minimal invasive techniques, complications arising from the use of anterior minimally invasive surgery (AMIS) for THA on a traction table are not well documented. Our study aims to focus on nerve damage during the AMIS procedure and the possible explanations of these injuries. METHODS: We reviewed all primary THAs performed with the AMIS technique using a traction table, over 5 years and recorded all intraoperative and postoperative complications up to the latest follow-up...

BACKGROUND: Direct to consumer (DTC) advertising, targeting the public over the physician, is an increasingly pervasive presence in medical clinics. It is trending toward a format of online interaction rather than that of traditional print and television advertising. METHODS: We analyze patient-focused Web pages from the top 5 companies supplying prostheses for total hip arthroplasties, comparing them to the top 10 independent medical websites. Quantitative comparison is performed using the Journal of American Medical Association benchmark and DISCERN criteria, and for comparative readability, we use the Flesch-Kincaid grade level, the Flesch reading ease, and the Gunning fog index...

BACKGROUND: The minimally invasive direct anterior approach (MDAA) has been reported to be useful in total hip arthroplasty. The benefits of this approach may be useful for the treatment of femoral neck fractures. Aim of this study is to compare MDAA and postero-lateral approach (PLA) in patients treated with hip hemiarthroplasty for femoral neck fractures. MATERIALS AND METHODS: Between 2013 and 2014, 109 patients underwent bipolar hip hemiarthroplasty for femoral neck fracture: 88 female and 21 male with a mean age of 88 years old...

The utilization of hip arthroscopy is rapidly increasing due to improved arthroscopic techniques and training, better recognition of pathology responsible for non-arthritic hip pain and an increasing desire for minimally invasive procedures. With increasing rates of arthroscopy, associated complications are also being recognized. We present a series of six patients who experienced psoas tunnel perforation during anchor insertion from the distal anterolateral portal during labral repair. All patients underwent prior hip arthroscopy and labral repair and presented with persistent symptoms at least partly attributable to magnetic resonance imaging (MRI)-documented psoas tunnel perforation...

The minimal invasive anterolateral Yale 2-incision approach for total hip arthroplasty aims minimizing damage to the muscles for faster recovery of function. Therefore the hypothesis was investigated, that during the rehabilitation process the Yale approach shows a faster return to natural gait than a conventional lateral approach. Nineteen patients had the Yale, 16 the conventional Bauer approach. Instrumented gait analysis was performed 3 days, 3 and 12 month post operatively. Velocity, cadence, step length, weight bearing, thorax lean, Trendelenburg limp, hip abduction moments, and hip muscle activation times were evaluated...

The aim of this article is to describe a minimally invasive iliac crest-sparing approach (ICSA) allowing common iliac osteotomies in children. The ICSA was used for 98 hips in 72 consecutive patients who underwent a pelvic osteotomy. The mean follow-up duration ranged from 3 to 7 years. Skin incision ranged from 3 to 5.5 cm. Displacement of the distal osteotomy fragment was easy and without tension. The duration of surgery varied from 50 min in the beginning of our experience to 20-25 min for the last cases of the series...
