Do All Postoperative Vancouver B2 Fractures Require Revision Arthroplasty With Cementless Stems?

Background: Management of periprosthetic fractures has been guided by the Vancouver classification, which recommends revision for fractures around a loose femoral implant (B2). New studies have challenged this approach, demonstrating acceptable outcomes with internal fixation. This study evaluates our experience with Vancouver B2 fractures, comparing internal fixation to femoral revision. We hypothesized that in select cases with cementless stems, internal fixation would provide acceptable results with reduced morbidity. Methods: A retrospective review was performed of periprosthetic hip fractures treated at our institution between 1 January 2012 and 4 November 2022. We excluded patients who did not have prior radiographs and evidence of stem subsidence, suggestive of a Vancouver B2 fracture. Thirteen patients were included in the analysis. Results: Four patients (31%) underwent revision of the femoral component, 4 patients (31%) underwent plating, and 5 patients (38%) underwent internal fixation with cerclage cabling. The average operative duration was 158 minutes, 203 minutes, and 62 minutes for the revision, plating, and cabling cohorts, respectively (P = .009). Blood loss was 463 cc, 510 cc, and 90 cc for the revision, plating, and cabling cohorts, respectively (P = .036). Three patients in both the revision and plating cohorts each received a transfusion (75%), whereas no patients in the cabling cohort required a transfusion (P = .033). All patients demonstrated fracture healing on the postoperative radiographs. No patients required additional surgery during the follow-up period. Conclusions: We have demonstrated that Vancouver B2 periprosthetic fractures with intact lateral cortices may be treated with internal fixation with cerclage cabling with excellent results.

The Development and Early Experience of a Destination Center of Excellence Program for Total Joint Arthroplasty.

High-volume total joint arthroplasty centers are becoming designated as destination centers of excellence to ensure quality of care while containing costs. This study aimed to evaluate the surgical patient journey through a new destination center of excellence program, review acute perioperative course trajectories, and report clinical outcomes. Our institution developed and implemented a destination center of excellence program to integrate into the existing total joint arthroplasty practice. A retrospective record review and analysis were performed for the first 100 destination center of excellence total knee arthroplasties and total hip arthroplasties enrolled in the program to evaluate program efficacy at a minimum 1-year follow-up. The study initially screened 213 patients, of whom 100 (47%) met program criteria and completed surgery (67 total knee arthroplasties and 33 total hip arthroplasties). The complication rate was 2%, and five patients (7.5%) required manipulation under anesthesia for stiffness after total knee arthroplasty. Two reoperations were needed: a neurectomy after total knee arthroplasty and a revision after total hip arthroplasty. The early experience of a destination center of excellence program has been favorable, with low complication rates and excellent outcomes.

A Crossover Cohort of Direct Anterior vs Posterolateral Approach in Primary Total Hip Arthroplasty: What Does the Patient Prefer?

BACKGROUND: The utilization of the direct anterior approach (DAA) for total hip arthroplasty (THA) continues to markedly increase. Despite proposed advantages, there are limited data regarding outcomes of staged bilateral THA via 2 different approaches in the same patient. The purpose of this study was to elucidate patient perspective on the THA approach in a crossover cohort of patients who underwent consecutive THAs via the posterolateral approach (PLA) followed by a contralateral DAA. METHODS: A retrospective chart review and telephone interview were performed on 37 patients who underwent both THA approaches by a single surgeon from 2009 to 2019. Perioperative outcomes, complications/reoperations, and the patient-preferred approach were collected. The mean clinical follow-up was 105 and 44 months after PLA and DAA, respectively. RESULTS: After DAA THA, patients demonstrated lower postoperative day 1 visual analog scale pain scores (1.8 vs 2.9, P = .016) and ambulation (239 feet vs 31 feet, P < .001). The length of stay was significantly less (P < .001) for the DAA (1.9 days) compared with the PLA (3.1 days). There were no major complications or reoperations in either cohort. Most patients (26/37, 70%) preferred the DAA and stated that it was easier to recover from (30/37, 81%). CONCLUSION: In the same patient direct comparison, the DAA for THA may lead to less pain and improved ambulation in the early postoperative period. Furthermore, most patients prefer the DAA and believe it is easier to recover from than the PLA.

Single-use instrumentation, cutting blocks, and trials decrease contamination during total knee arthroplasty: a prospective comparison of navigated and nonnavigated cases.

The purpose of this prospective controlled trial was to determine whether decrease in contamination could be achieved in nonnavigated and navigated total knee arthroplasties by replacing traditional saws, cutting blocks, and trials with specialized saws and single-use cutting blocks and trials. Various tray wrapping metrics during total knee arthroplasty were measured in 400 procedures performed by 8 different surgeons at 6 institutions. Instrumentation contamination was determined by counting the number of tray sterility indicators, pans, and instruments that were compromised. The results show that a decrease in contamination was evident in 57% (nonnavigated) and 32% (navigated) fewer compromises of tray sterility indicators, pans, and instruments. Single-use instruments show promising benefits, but further study is needed to confirm safety and efficacy before they can be widely adopted. The authors believe that the use of single-use instruments, cutting guides, and trial implants for total knee arthroplasty will play an increasing role in decreasing operating room contamination and potential deep infections.

Acute onset of deep peroneal neuropathy during a golf game resulting from a ganglion cyst.

We report a case of sudden onset of deep peroneal neuropathy resulting from a ganglion cyst. Electrophysiology demonstrated a severe deep peroneal neuropathy with axonal loss and probably proximal conduction block. Magnetic resonance imaging demonstrated a mass arising from the proximal tibiofibular joint extending along the peroneal nerve. Surgical resection of the ganglion resulted in gradual improvement of strength. Peroneal nerve ganglia should be considered in the evaluation of patients with sudden painless foot drop.
