BACKGROUND: The aim of this study was to present the long-term survivorship (20 years) of total elbow arthroplasty (TEA) for a relatively large population and to compare different prosthesis brands and patient subgroups. METHODS: Between 1994 and 2017, a total of 838 primary TEAs were reported to the Norwegian Arthroplasty Register. Implant survival was calculated using the Kaplan-Meier method. Risk differences were examined using Cox regression analyses and exact Cox regression for rare events...

PURPOSE: Antibiotic-loaded acrylic cement (ALAC) spacers are useful for treatment of infected prostheses in the course of a two-stage revision. Spacers are handmade or are made using a commercial template, with reportedly good treatment outcomes. This study aimed to confirm the usefulness of custom-made ALAC spacers shaped like bipolar hip prostheses using a dental silicone template for treatment of infected hip prostheses, and described their manufacture. METHODS: This study evaluated 10 patients who underwent two-stage revision for treatment of infected hip prostheses...

BACKGROUND: Hip dislocations are a common presentation in the Emergency Department (ED) and require urgent reduction to reduce the risk of avascular necrosis. Over 90% of all dislocations can successfully be reduced in the ED and there is evidence that cases awaiting operative reduction result in significant delays. DISCUSSION: While there is limited data comparing specific techniques, the individual success rates of most maneuvers range from 60-90%. Additionally, each technique has distinct advantages and limitations associated with its use...

Dislocation after total hip arthroplasty (THA) remains a devastating complication and a primary cause for revision arthroplasty. Historical data indicate that a posterior approach is associated with a higher dislocation rate. In this study, we present a highly reliable and anatomical reconstruction, based on the biomechanical findings of a previous cadaveric experiment. The posterior soft tissues were repaired in 2 layers. First a reattachment of the posterior orbicular ligament is performed at the anterior capsule...

Our purpose is to evaluate the complications of open hip dislocation, which is used as a helpful technique in hip surgery. We have retrospectively reviewed 45 hips of 44 cases who applied open hip dislocation with various indications in our institute between the years 2006-2013. There were 27 males and 17 females whose mean age was 31,9 (range, 11-58) years with mean follow-up time of 56,9 months (range, 13-106). The number of cases with at least one complication related to open hip dislocation was 27. Within our series 14 hips have developed only 1 complication, 1 hip have 2, 10 hips have 3 and 2 hips have 4 different complications...

CASE: A 68-year-old woman who had undergone a right total hip arthroplasty presented with a right posterior hip dislocation, and subsequently developed an ipsilateral sciatic nerve palsy after closed reduction. Magnetic resonance imaging (MRI) with metal suppression demonstrated sciatic nerve entanglement around the prosthetic femoral neck. A sciatic nerve release was performed, resulting in poor early neurologic recovery. CONCLUSION: Sciatic nerve entanglement following closed reduction of a dislocated total hip prosthesis is a rare injury...

AIM: To measure the sensitivity and specificity of the cup version assessment by using only anteroposterior hip and pelvis views, evaluate the incidence of inadequate cup version in patients with repeated dislocations after total hip arthroplasty (THA). METHODS: Radiographic retrospective analysis of 2 groups of patients, with follow up of 6-60 mo, after undergoing primary THA. First group of 32 patients (20 female, 12 male) with unilateral THA (32 hips) required early revision arthroplasty for reasons of dislocation...

BACKGROUND: Sitting radiographs have been used as a pre-operative tool to plan patient-specific total hip arthroplasty (THA) component position that would improve hip stability. Previous work has demonstrated that spinal mobility may impact functional acetabular position when seated. We sought to determine whether patients who dislocate following THA have different sitting spinopelvic alignment or acetabular component orientation compared to patients who did not dislocate. METHODS: A consecutive series of 1000 patients underwent post-operative low-dose biplanar spine-to-ankle lateral radiographs in standing and sitting positions 1 year following THA...

BACKGROUND: Total hip arthroplasty is one of the most commonly performed surgical procedures worldwide. There are a number of surgical approaches for total hip arthroplasty and no high-level evidence supporting one approach over the other. Each approach has its unique benefits and drawbacks. This trial aims to directly compare the three most common surgical approaches for total hip arthroplasty. METHODS/DESIGN: This is a single-centre study conducted at Western Health, Melbourne, Australia; a large metropolitan centre...

PURPOSE: The minimally invasive (MI) anterolateral approach is a relatively new approach for the treatment of femoral neck fractures with a hemiarthroplasty (HA). There is limited research available presenting clinical outcomes after an HA using the MI approach. Therefore the aim of the present study was to compare clinical outcomes of the MI and traditional anterolateral approaches in patients after HA. METHODS: Data were extracted from a prospective hip fracture database and completed by retrospective review of the electronic medical records...

AIMS: Dislocation rates are reportedly lower in patients requiring proximal femoral hemiarthroplasty than for patients undergoing hip arthroplasty for neoplasia. Without acetabular replacement, pain due to acetabular wear necessitating revision surgery has been described. We aimed to determine whether wear of the native acetabulum following hemiarthroplasty necessitates revision surgery with secondary replacement of the acetabulum after proximal femoral replacement (PFR) for tumour reconstruction...

B Darrith, P M Courtney, C J Della Valle
AIMS: Instability remains a challenging problem in both primary and revision total hip arthroplasty (THA). Dual mobility components confer increased stability, but there are concerns about the unique complications associated with these designs, as well as the long-term survivorship. MATERIALS AND METHODS: We performed a systematic review of all English language articles dealing with dual mobility THAs published between 2007 and 2016 in the MEDLINE and Embase electronic databases...

PURPOSE: The purpose of this study was to determine if there were significant differences between patients submitted to hip arthroscopy (HA) and surgical hip dislocation (SHD) to treat femoro-acetabular impingement (FAI), which variables were significantly associated with hip function before surgery and those predictive of the applied functional outcome scale and its variation rate after surgery. METHODS: We selected 198 patients treated with HA or SHD with a mean follow-up of 59 months...

Background: Multiple approaches to the hip joint have been developed utilizing various intervals and/or intermuscular planes when performing a total hip arthroplasty (THA), each proposing certain advantages. Of these, the Röttinger approach (modified anterolateral or Watson-Jones) is potentially muscle-sparing. Multiple studies have demonstrated favorable outcomes with this approach. However, others showed more complications with a slow learning curve. Due to the paucity of evidence we conducted this study to: (I) present our operative experience and technique of the Röttinger approach; (II) compare short-term complications and operative room (OR) times of this approach to the direct lateral; and (III) review the available literature...

BACKGROUND: We argue that 1-stage bilaterally total hip arthroplasty (THA) could be acceptable in bilateral coxarthrosis because of high-riding developmental dysplasia of the hip (DDH). METHODS: Sixty-nine cases (51 patients) of high-riding DDH in patients who underwent THA from 2010 to 2013 were reviewed. Patients were divided into 2 groups: unilateral (group 1) and 1-stage bilateral surgery (group 2). The clinical measurements were the visual analog scale and Harris Hip Score...

PURPOSE: To investigate the arthroscopic pathoanatomy of the transverse acetabular ligament (TAL) and determine whether a TAL incision is necessary for the concentric reduction of developmental dysplasia of the hip (DDH) in infants and young children. METHODS: We retrospectively reviewed patients who underwent arthroscopic-assisted reduction for DDH between July 2008 and April 2016. The indications for this intervention included patients in whom closed reduction failed and those who did not require bone operations...

CASE: A patient was struck by an agricultural vehicle and sustained ipsilateral hip and knee dislocations. Closed reduction of the hip was accomplished in the emergency department; the patient required general anesthesia in the operating room to reduce the knee dislocation. Nonoperative treatment was used for both injuries, with a good long-term outcome. CONCLUSION: Simultaneous ipsilateral hip and knee dislocations are rare and complex injuries that usually result from high-energy trauma...

INTRODUCTION: Pigmented villonodular synovitis (PVNS) is a rare, destructive synovial disease that affects the hip joint the second most common after the knee. However, in contrast, joint preserving surgery in the hip joint is considered to be significantly more difficult or even impossible due to earlier occurrence of osteochondral dissemination and surgical difficulties. Today, earlier diagnosis due to the generous use of MRI and modern surgical strategies raise hope for improved outcomes...

We present the case of a 13-year-old boy who sustained a locked central fracture dislocation of the right acetabulum following a bicycle fall. Immediate external reduction maneuvers under general anesthesia were unsuccessful due to intrapelvic entrapment of the femoral head. Open reduction internal fixation was achieved 48 hours later. After an initial satisfactory postoperative course, the patient ended up developing severe hip osteoarthritis 16 months after the procedure. The rarity of this injury in children is discussed, with its possible implications on joint congruity and potential growth injury...
