Study: Neural Network Deep Learning Model Effectively Identifies Failed Total Joint Implant Designs

According to a study published in the May 1 issue of the Journal of the AAOS ®, a convolutional neural network deep learning model accurately identified the make and model of implants in failed total hip arthroplasties (THAs) and total knee arthroplasties (TKAs). A deep learning model was trained to identify designs from 11,204 anterior-posterior radiographs. The computational model discriminated 17 THA designs with an area under the receiver operating curve (AUC) of 0.98 and eight TKA designs with an AUC of 0.97. The deep learning model had AUCs of 0.98 and 0.96 for revision THA and revision TKA designs, respectively.

Study: Favorable Outcomes at Midterm Follow-up after Arthroscopic Latarjet Procedure

Arthroscopic Latarjet procedures led to excellent clinical and radiological outcomes, few complications, and high rates of satisfaction and return to work and sport at a mean of six years postoperatively, according to a retrospective study published online in The Journal of Arthroscopy. Patients aged >18 years who were treated between 2011 and 2017 were evaluated. Out of 95 shoulders, 97.8 percent returned to the same preoperative working conditions, all athletic patients (91.4 percent) returned to sport postoperatively, and 97.9 percent were satisfied with their surgery. The complication rate was 5.4 percent and more common in older patients.

In a randomized trial published online in The Journal of Hand Surgery, elastic tape or a cast were similarly effective immobilization options in addition to three-point prefabricated orthosis for nonsurgical management of mallet finger. Seventy patients underwent six weeks of full-time immobilization with either elastic tape or a cast for distal interphalangeal joint extension. Follow-up occurred at 12 weeks after immobilization and six months postinjury. There was no significant difference found between the groups in terms of joint extension and flexion, function, and pain.

Treatment with daily prednisone or deflazacort led to significant improvements, including better motor and pulmonary function, compared with use of intermittent prednisone in children with Duchenne muscular dystrophy, according to a randomized trial published online in JAMA. A total of 196 boys aged four to seven years without previous corticosteroid treatment received either daily prednisone, daily deflazacort, or intermittent prednisone. Patients were followed for three years. Both daily prednisone and deflazacort were more effective than intermittent prednisone. The most common adverse events were abnormal behavior, upper respiratory tract infection, and vomiting.

This month, Michigan Governor Gretchen Whitmer signed the Health Can’t Wait Act, legislation aimed at reducing prior authorization wait times and streamlining how physicians and payers interact. The overarching goal of the measure is to reduce the difficulty and administrative burden of navigating insurer utilization management policies. The new law requires state-regulated health insurance plans to offer a standardized electronic prior authorization process and established and defined time frames and emphasizes the need for evidence-based clinical review guidelines.
