Project description:Neglected anterior hip dislocation combined with comminuted pertrochanteric ipsilateral fracture of the femur is rare, with few reports in the literature. The present report describes the case of a 7-month-old neglected anterior hip dislocation with a pertrochanteric femoral fracture in a 45-year-old male patient. The patient was treated with total hip arthroplasty with proximal femoral reconstruction. The 2-year follow-up showed good clinical and radiological outcomes with a painless and mobile hip joint. The Harris-Hip score improved from 10 (preoperatively) to 89 (postoperatively) after 2 years. The patient was satisfied with the intervention and showed minimal lurch with ambulation with no leg-length discrepancy. However, long-term results from periodic follow-up are warranted.

Project description:BackgroundThe use of cementless femoral stems in patients undergoing primary total hip arthroplasty (THA) with Dorr C bone remains controversial for fear of fracture or subsidence. Purpose of this multicenter study was to compare clinical outcomes and complications of THA using a tapered femoral prosthesis in patients with Dorr C bone versus Dorr A/B bone.MethodsA total of 1,030 patients underwent primary THA with a tapered wedge femoral stem at a minimum one year follow up. Forty-eight patients with Dorr C bone (mean age 68.7 years) were compared with a matched cohort of patients with Dorr A/B bone (mean age 69.9 years). Mean follow-up was approximately 4 years in both cohorts. There were no differences in sex, age, body mass index (BMI), Harris Hip Score (HHS), complications, and radiographic outcomes including subsidence and aseptic loosening were evaluated.ResultsPostoperative HHSs were a mean of 82 points in the Dorr C cohort compared to 84 points in the Door A/B cohort (P=0.2653). There was no significant difference in complication or revision rates for any reason (P=0.23). Mean subsidence for the Dorr C and Dorr A/B was 1.4 and 1.2 mm, respectively (P=0.5164), and there was no aseptic loosening of the femoral component found in either group.ConclusionsCurrent generation tapered wedge cementless femoral stems provide stable fixation for patients with Dorr C bone quality without increased complications with respect to fracture or subsidence and can be considered an alternative to cemented stems in patients with compromised bone quality.

Project description:We present a unique case of bladder perforation occurring intraoperatively during primary total hip arthroplasty. It is suspected that the patient's aberrant bladder anatomy, with idiopathic erosion of the quadrilateral space, predisposed the patient to bladder injury. Several preoperative risk factors for bladder injury were identified in the literature. These factors include cemented acetabular components, previous history of hip arthroplasty, history of pelvic trauma or intrapelvic surgery, and poor bone quality. Management of bladder injury, should it occur, includes bladder decompression with a Foley catheter, antibiotic administration, hemodynamic monitoring, and urology consult with close follow-up. This case reinforces the importance of urologic preoperative evaluation for anatomic variations of the bladder. In such cases, intraoperative Foley catheters to prevent distension may reduce the risk of perforation.

Project description:BackgroundThere is now a clear trend with increased usage of cementless femoral stems for all ages and most patients. As the number of total hip arthroplasties (THAs) performed annually continues to increase with expanding indications for THA and demands for improved quality of life, so will the prevalence of THA in the elderly and aging populations. This is worrisome as the risk of complications with cementless femoral stems increases in elderly patients and those with poor bone quality. The purpose of this study is to analyze the available data from comparative studies to determine whether cementless femoral stems are overused and whether cemented stems warrant increased consideration.MethodsUsing Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searches were performed to find original studies comparing cementless and cemented femoral stems; large population registry studies and reports were also included.ResultsThis systematic review documents that older patients with cementless fixation increase the risk of revision, there is no clear fixation advantage in midaged patients, and younger patients fare better with cementless fixation. Complications after THA create burdens on the health care system and on patients.ConclusionsUsing evidence-based data should be better guidance in selecting the most reliable implants for THA. Although cementless femoral fixation for THA has evolved to the "new standard," it has not been proven to be the "gold standard" for all patients.

Project description:As surgeons' comfort with the direct anterior approach (DAA) for total hip arthroplasty continues to increase, there is a growing interest in performing complex surgeries through this approach. Acetabular bone loss and/or pelvic discontinuity in the primary or revision setting often requires specialized implants such as a cup-cage construct. We describe our surgical technique for implanting modified cup-half cages through the DAA and show 2 case examples of how this technique was utilized in the setting of complex acetabular bone loss. In our experience, this is an effective method for complex total hip arthroplasty, with the potential added benefits of the DAA of reduced soft-tissue dissection, direct measurement of leg length, and ease of fluoroscopic navigation for implant positioning.

Project description:Cementless total hip arthroplasty has achieved reliable long-term results since porous coatings were developed, but postoperative changes around the stem remain poorly documented. In this study, changes of the bone mineral density (BMD) were compared between two types of cementless stem. In group B (28 patients with 31 hips), a straight tapered stem with porous plasma spray coating on the proximal 1/4 was used, while group S (24 patients with 26 hips) was given a fluted, tri-slot stem with porous hydroxyapatite coating on the proximal 1/3. In group B, there was an early decrease of BMD, which recovered after 12 months, indicating that stress shielding was minimal. In group S, however, BMD continued to decrease without recovery. The stem shape and radiological findings suggested that the cause of stress shielding in group S was distal fixation.

Project description:Conversion of a failed surface hip replacement to a conventional total hip arthroplasty is reportedly a straightforward procedure with excellent results. We compared perioperative parameters, complications, and clinical as well as radiographic outcomes of 39 hemi and total hip resurfacing conversions with conventional THAs. The hips were matched by diagnosis, gender, age, body mass index, preoperative Harris hip score, and followup time to a cohort of primary conventional THAs performed during the same time period by the same surgeon. The mean operative time was longer (by 19 minutes) for the conversions, but other perioperative parameters were similar. At a mean followup of 45 months (range, 24-63 months), the mean Harris hip scores were similar in the two groups (92 points versus 94 points for the conversion and conventional hips, respectively). Thirty-eight of 39 stems were well-aligned and appeared osseointegrated. When a resurfaced hip fails, conversion to conventional THA has similar early clinical and radiographic outcomes to primary conventional THA.Level III, therapeutic (retrospective comparative study). See the Guidelines for Authors for a complete description of levels of evidence.

Project description:BackgroundThe introduction of new devices for total hip arthroplasty (THA) offers surgeons the ability to address deficits in the portfolio. However, once introduced, data regarding the performance of devices is not publicly available until their use is widespread.Purpose/questionsThe objective of this study was to compare the clinical and radiographic performance, including patient reported outcomes and radiographic evidence of osseointegration, subsidence, and stress shielding, of the newer Actis femoral component to the Corail stem (DePuy Synthes, Warsaw, IN, USA), which has an extensive clinical history.MethodsThis short-term, retrospective cohort study was a single surgeon series of 330 anterior approach THAs, consisting of 165 cases using the Actis stem and 165 cases using the Corail stem. Both devices were cementless, titanium, tapered, hydroxyapatite-coated stems. They differed in geometry, neck choices, broach philosophy, and collar availability. Data was obtained for 1 year following THA. Functional outcomes were measured with the Hip Dysfunction and Osteoarthritis Outcome Score for Joint Replacement (HOOS, JR.) survey. Complications were recorded from patient charts, and radiographic analysis was performed for signs of osseointegration, subsidence, and stress shielding.ResultsThe groups shared similar demographic characteristics except the Actis population was younger with fewer women. The complication rate did not significantly vary, and no patient required revision within the first year. Radiographically, one patient in each group demonstrated subsidence. No cases exhibited radiolucent lines, and the prevalence of stress shielding at 1 year was comparable. HOOS, JR. scores did not significantly vary at 8 weeks or 1 year.ConclusionThe Actis stem does not carry an increased risk of device-related complications compared with the Corail implant. Although aspects of bone remodeling differed between groups, Actis achieved radiographic signs of bone ingrowth at the 1-year mark and performed well clinically, with equivalent patient reported outcome scores to the Corail stem.

Project description:BackgroundThe purpose of this study is to evaluate survivorship and outcomes of high-activity patients compared to low-activity patients after total hip arthroplasty.MethodsA retrospective review identified 2002 patients (2532 hip) that underwent a primary total hip arthroplasty with vitamin E-infused highly crosslinked polyethylene liner. Patients were divided into 2 groups based on their University of California Los Angeles (UCLA) activity level: low activity (LA) (UCLA ≤5) and high activity (HA) (UCLA ≥6). Outcomes included Harris Hip Score, UCLA activity score, and reoperations. A multivariate nominal regression analysis was performed to evaluate the significance of postoperative activity level on survivorship.ResultsThe mean follow-up duration was 4.5 years (range, 0.3 to 9.9 years). HA group had significantly higher improvements in Harris Hip Score (HHS) (P < .001) and UCLA activity score (P < .001). Aseptic revisions were performed in 2.1% of the LA group and in 0.4% hips of the HA group (P < .001). After controlling for age, gender, preoperative pain, HHS, and body mass index, a higher postoperative activity level remained a significant factor for improved aseptic survivorship with an odds ratio of 4.9 (95% confidence interval, 1.1 to 21.2, P = .03). The all-cause 5-year survivorship was 99% for the HA group and 96% to for the LA group (P < .001). The aseptic 5-year survivorship was 99.6% for the HA group and 98% for the LA group (P < .001).ConclusionsThis study found that a higher activity level after primary THA was not deleterious to survivorship at short to midterm follow-up with modern implants.
