Management of persistent postpartum pelvic pain

Persistent postpartum pelvic pain is an uncommon but disabling disorder. Although symptoms resolve spontaneously in the majority of cases, some carefully selected women with this chronic condition might benefit from surgical stabilization of the pelvic ring. We retrospectively studied 19 patients whose persistent postpartum pelvic pain was treated at our center. Although most patients were successfully treated nonoperatively, 6 (31.5%) underwent surgery because of symptoms persisting more than 1 year. Imaging studies, including magnetic resonance imaging, were used to assess the extent and the nature of the lesion before surgery. Eleven patients had degenerative changes in the anterior pelvic ring; the other 8 patients had degenerative sacroiliac joint changes. Surgical procedures included resection of the diseased fragment, anterior symphyseal plating, and bone grafting with and without posterior ring stabilization. For all patients, mean Majeed outcome score was 85 (range, 46-100). No significant difference in outcomes was found between the surgically treated patients and the nonoperatively treated patient

Training femoral neck screw insertion skills to surgical trainees: computer-assisted surgery versus conventional fluoroscopic technique

BACKGROUND: Femoral neck fractures are among the most common orthopaedic injuries impacting the health care system. Surgical management of such fractures with cannulated screws is a commonly performed procedure. The acquisition of surgical skills necessary to perform this procedure typically involves learning on real patients with fluoroscopic guidance. This study attempts to determine if a novel computer-navigated training model improves the learning of this basic surgical skill. METHODS A multicenter, prospective, randomized, and controlled study was conducted using surgical trainees with no prior experience in surgically managing femoral neck fractures. After a training session, participants underwent a pretest by performing the surgical task (screw placement) on a simulated hip fracture using fluoroscopic guidance. Immediately after, participants were randomized into either undergoing a training session using conventional fluoroscopy or computer-based navigation. Immediate posttest, retention (4 weeks later), and transfer tests were performed. Performance during the tests was determined by radiographic analysis of hardware placement. RESULTS Screw placement by trainees was ultimately equal to the level of an expert surgeon with either training technique. Participants who trained with computer navigation took fewer attempts to position hardware and used less fluoroscopy time than those trained with fluoroscopy. When those trained with fluoroscopy used computer navigation at the transfer test, less fluoroscopy time and dosage was used. The concurrent augmented feedback provided by computer navigation did not affect the learning of this basic surgical skill in surgical novices. No compromise in learning occurred if the surgical novice trained with one type of technology and transferred to using the other. CONCLUSIONS The findings of this study suggest that computer navigation may be safely used to train surgical novices in a basic procedure. This model avoids using both live patients and harmful radiation without a compromise in the acquisition of a 3-dimensional technical skill

How resources affect management of periprosthetic fractures of the distal femur: perspectives from Israel, South Sudan, and South Africa

Summary:. Periprosthetic fractures of the distal femur have significant morbidity in both total hip and total knee arthroplasty (THA and TKA, respectively). The incidence of these fractures is growing, with the predominant mechanism of injury being a fall from a standing height and therefore considered fragility fractures. In many countries, improved public funding and a flourishing private health care sector, when coupled with increased life expectancy, translates to more older patients receiving both TKA and THA and therefore an increased prevalence of periprosthetic fractures and their associated complications. These fractures may occur below a long stem THA, above a TKA, or between the two (so-called “interprosthetic fracture”). We will outline fracture classification, risk factors, diagnosis, and treatment options, highlighting perspectives on treating these fractures in Israel, South Africa, and South Sudan. These countries represent differing access to resources, varied comorbidity factors, and differing health care systems. The points of difference and the points of similarity will be considered
