Study Assesses Use of Overnight Interventions in TJA Patients
According to a study published in the January issue of The Journal of Arthroplasty, most patients who undergo total joint arthroplasty (TJA) do not require overnight interventions. Between 2012 and 2017, a single surgeon performed 1,725 consecutive primary unilateral TJAs. A total of 759 patients were discharged on postoperative day one, most of whom (n = 641) did not receive medical interventions during their overnight hospital stay. Overnight interventions included treatments (n = 90), in and out catheterizations for urinary retention (n = 29), and diagnostic tests (n = 12). Eleven diagnostic tests were negative, and two-thirds of treatments were intravenous fluids for oliguria or hypotension.
A retrospective study published in the Jan. 15 issue of the Journal of the AAOS ® evaluated reasons for primary total hip arthroplasty (THA) failure. Between January 2010 and May 2019, 535 revisions were performed on 444 THAs at a single institution. The average time to revision was 8.51 years; 136 cases were performed within two years after primary surgery. The main reasons for revision were mechanical failure (n = 162), metallosis (n = 95), dislocation or instability (n = 65), periprosthetic failure (n = 46), infection (n = 44), hematoma or poor wound healing (n = 15), and pain or other (n = 17).
Study Evaluates Correlation Between Glenoid Retroversion and Bankart Repair Failure
A study published online in Arthroscopy determined whether glenoid retroversion was an independent risk factor for failure after arthroscopic Bankart repair. The retrospective study consisted of two parts. First, patients with no glenoid bone loss were compared by whether they failed (cases, n = 20) or did not fail Bankart repair (controls, n = 40). Then, cases with glenoid bone loss and failed repair (n = 19) were compared to controls who did not have failed repair (n = 21). In part one, glenoid version did not differ between cases and controls. In part two, cases had significantly less mean retroversion than controls.
Study: Distal Nerve Transfers for Claw Correction Following Proximal Ulnar Nerve Lesions
A retrospective study published online in The Journal of Hand Surgery observed no cases of claw correction after anterior interosseous nerve end-to-end transfer to the deep motor branch of the ulnar nerve in high ulnar nerve injuries. A total of 11 patients underwent surgery an average five months after injury. Patients were followed for an average 19 months postoperatively, at which time all patients presented clawing. The average proximal interphalangeal joint extension lag was 46.8 degrees in the fourth digit and 57.7 degrees in the fifth digit.
Study Examines Effect of Age on Timing of Recurrence Following Microdiskectomy for Lumbar Disk Herniation
A study published online in the European Spine Journal did not observe a higher probability for reoperation in younger patients undergoing microdiskectomy for lumbar disk herniation (LDH). A prospective registry was used to identify 3,013 patients who underwent tubular microdiskectomy for LDH. Overall, 166 patients (5.5 percent) required reoperation due to LDH recurrence. Uni- and multivariable analysis did not observe a relationship between age and LDH recurrence, but linear regression observed that, with and without correcting for confounders, older patients required earlier reoperation. Patients aged older than 35 years sustained LDH much earlier.
AJRR Data Reveal Migration Patterns for Revision TKA
Data from the American Joint Replacement Registry (AJRR) indicate that revision surgery following primary total knee arthroplasty (TKA) takes place at medium and large teaching institutions and migrates away from small, nonteaching institutions. Migration to medium and large teaching institutions was significantly more likely when revision TKA was for an infection. Kevin Lawson, MD, presented the study as part of the 30th American Association of Hip and Knee Surgeons Annual Meeting.
With the initial distribution and administration of a COVID-19 vaccine underway across the globe, AAOS reiterated the importance of evaluating scientific evidence when weighing the risks and benefits of a vaccination’s effects on the musculoskeletal system. To date, there is no high-quality evidence that indicates vaccinations administered correctly to the shoulder area can injure the shoulder.
