Introduction: Joint dislocation is one of the most frequent complications after hip arthroplasty. Multiple strategies have demonstrated ability to prevent instability when used in isolation, but the effect when more than one intervention is implemented has not been measured. The purpose of this study is to assess the rate of dislocation after implementation of a protocol of combined strategies for prevention of instability. Materials and methods: Consecutive patients undergoing primary total hip replacement for hip osteoarthritis between February 2012 and June 2014 were included...

Background: Cauda equina syndrome (CES) is a rare complication of spinal or epidural anesthesia. It is attributed to direct mechanical injury to the spinal roots of the cauda equina that may result in saddle anesthesia and paraplegia with bowel and bladder dysfunction. Case Description: The first patient underwent a hip replacement and received 5 mL of 1% lidocaine epidural anesthesia. Postoperatively, when the patient developed an acute CES, the lumbar magnetic resonance imaging (MRI) scan demonstrated clumping/posterior displacement of nerve roots of the cauda equina consistent with adhesive arachnoiditis attributed to the patient's previous L4-L5 lumbar decompression/fusion...

The aim of this study was to report on 2 patients in whom metal-on-metal (MOM) facet replacements failed, with subsequent positive findings on allergy testing. Motion-preserving devices have been used with limited success when instrumentation is indicated in the mobile spine. MOM-bearing surfaces in orthopedics were developed to increase implant longevity, yet have been associated with numerous adverse outcomes, including local tissue reactions, pseudotumors, metallosis, and the need for revision surgery. Five patients with spinal stenosis and low-grade spondylolisthesis were randomized to undergo facet replacement surgery with the ACADIA facet replacement system at the authors' institution...

BACKGROUND: Cup malposition is a common cause of impingement, limitation of ROM, acceleration of bearing wear, liner fracture, and instability in THA. Previous studies of the safe zone based on plain radiographs have limitations inherent to measuring angles from two-dimensional projections. The current study uses CT to measure component position in stable and unstable hips to assess the presence of a safe zone for cup position in THA. QUESTIONS/PURPOSES: (1) Does acetabular component orientation, when measured on CT, differ in stable components and those revised for recurrent instability? (2) Do CT data support historic safe zone definitions for component orientation in THA? METHODS: We identified 34 hips that had undergone revision of the acetabulum for recurrent instability that also had a CT scan of the pelvis between August 2003 and February 2017...

Background and purpose - The best treatment option for severe slipped capital femoral epiphysis (SCFE) is still controversial. We compared clinical and radiographic outcomes of modified Dunn procedure (D) and in situ fixation (S) in severe SCFE. Patients and methods - We retrospectively compared D and S, used for severe stable SCFE (posterior sloping angle (PSA) > 50°) in 29 patients (15 D; 14 S). Propensity analysis and inverse probability of treatment weights (IPTW) to adjust for baseline differences were performed...

Edge-loading of a ceramic-on-ceramic total hip replacement can lead to reproducible squeaking and revision. A patient's functional acetabular cup orientation, driven by their pelvic tilt, has been shown to be a significant factor in squeaking during hip flexion. The aim of this study was to investigate the effect of seated pelvic tilt on the contact mechanics at the ceramic bearing surface. A finite element model of a ceramic-on-ceramic total hip replacement was created. The cup was orientated at 40° inclination and 15° anteversion relative to the anterior pelvic plane...

BACKGROUND: Dislocation rates in posterior total hip arthroplasty (THA) range between 2% and 5%, but long-term course (recurrence of dislocation or revision surgery) is not known, most series having short follow-up or small populations. We therefore conducted a retrospective study on a large series, to determine long-term rates of recurrence and surgical revision and recurrence risk factors. HYPOTHESIS: Long-term follow-up of a large cohort of THA dislocations enables recurrence rate and factors to be determined...

INTRODUCTION: Operative treatment of acute acetabular fractures has shown better results than the non-operative approach. There is, however, limited data regarding the operative treatment of neglected acetabular fracture. METHODS: We present six subjects with neglected fracture of the acetabulum in Cipto Mangunkusumo National Hospital, Jakarta, Indonesia. One had only open reduction and internal fixation, three had open reduction and internal fixation first before we performed arthroplasty later, one had both open reduction and internal fixation with arthroplasty, and another had immediate arthroplasty...

PURPOSE: Acetabular cup positioning in extreme angles of vertical position affects both stability and long-term survivorship of total hip arthroplasty. The purpose of this study is to determine whether native Sharp's angle is associated with an increased abduction angle of the acetabular component. METHODS: Consecutive patients who underwent primary total hip replacement between February 2012 and August 2015 were included. Vertical positioning of acetabular implant in the antero-posterior post-operative radiographs were measured...

BACKGROUND: The omega approach represents a modification of the lateral approach to the hip for joint replacement. It was developed to reduce the potential for gluteus muscle dysfunction and thereby improve functional outcome following hip replacement. METHODS: A cohort of 415 consecutive hip replacements receiving the same type of cemented femoral component were followed up at a mean of three years postoperatively and invited to complete functional outcome and satisfaction scores...

Although several studies have described abnormal trunk motion before and after total hip arthroplasty (THA) surgery, few studies have examined trunk motion using accelerometry. The aim of this study was to determine whether abnormal trunk motion persisted after THA using accelerometry. A total of 24 female patients (61.0±6.9years) and 20 healthy female subjects (59.9±6.8years) participated in this study. Patients were assessed at 1 month prior to surgery and 12 months after surgery. Trunk acceleration during gait was measured using a triaxial accelerometer attached to the L3 spinous process...
