Inflammatory demyelinating polyneuropathy is a rare but devastating condition. Guillain-Barré syndrome is the most common cause with acute inflammatory demyelinating polyneuropathy being the most common subtype that follows a monophasic course and does not recur. Chronic inflammatory demyelinating polyneuropathy occurs when symptoms persist for greater than 8 weeks.

Intrathecal morphine (ITM) can be useful for postoperative analgesia following lower extremity joint arthroplasty, but concerns exist regarding potential dose-related side effects. In this study, we examined the safety and efficacy of ITM in patients undergoing lower extremity joint arthroplasty. We hypothesized that there would be (1) direct relationship between dosing and side effects, and (2) an inverse relationship between ITM dosing and 24-hour postoperative opioid requirement.

Background: To assess the relationship between rapidly destructive osteoarthritis (RDOA) of the hip and intra-articular steroid injections.

Methods: Coding records from 2000 to 2013 were used to identify all subjects who had a fluoroscopy-guided intra-articular hip injection to treat pain associated with primary osteoarthritis. Radiographic measurements from preinjection and postinjection imaging were evaluated with Luquesne's classification of RDOA to determine diagnosis (greater than 50% joint space narrowing or greater than 2 mm of cartilage loss in 1 year with no other forms of destructive arthropathy).

A feared complication of temporary surgical drain placement is from the technical error of accidentally suturing the surgical drain into the wound. Postoperative discovery of a tethered drain can frequently necessitate return to the operating room if it cannot be successfully removed with nonoperative techniques. Formal wound exploration increases anesthesia and infection risk as well as cost and is best avoided if possible.

Background: Despite literature to support the use of various cerclage techniques to address intraoperative femoral fractures in total hip arthroplasty, there are limited data to support prophylactic cerclage wiring of the femur during cementless implant placement. This study aims to evaluate the effect of prophylactic calcar cerclage wires on the biomechanical parameters required to produce periprosthetic femoral fractures and on the morphology of these fracture patterns in stable cementless femoral implants.

Methods: Ten pairs of matched fresh frozen cadaveric femurs were implanted with anatomic tapered cementless implants with or without the addition of 2 monofilament calcar wires.

Prosthetic joint infection (PJI) of the hip and knee remains one of the most common and feared arthroplasty complications. The impact and cost of PJI is significant, both to the patient and to the health care system. Recent reports of results of different treatment strategies have led many surgeons to modify their approach to management of PJI.

Article Synopsis
  • Most descriptions of the knee's extensor mechanism overlook its complexity and variations in structure.
  • A study of 20 cadaver limbs revealed only 3 showed the typical quadriceps tendon arrangement, with many presenting more intricate fiber patterns.
  • The medial patellofemoral ligament was found more frequently than the lateral one, highlighting its importance in stabilizing the patella, suggesting that understanding these anatomical differences could help with knee joint issues and total knee replacements.
