Treatment of periprosthetic fractures around hip resurfacings with cephalomedullary nails.

We describe 2 cases of proximal femoral fractures, 1 intertrochanteric and 1 subtrochanteric, distal to hip resurfacing implants that were managed successfully via internal fixation with trochanteric start point cephalomedullary nails. Both patients had pain-free, well-functioning implants with radiographically healed fractures at their 1-year follow-up. This novel approach offers several advantages over previously described techniques for these rare and difficult-to-treat fractures.

Risk factors for peroneal nerve injury and recovery in knee dislocation.

Background: Acute knee dislocation is rare but has a high rate of associated neurovascular injuries and potentially limb-threatening complications. These include the substantial morbidity associated with peroneal nerve injury: neuropathic pain, decreased mobility, and considerably reduced function, which not only impairs patient function but complicates treatment.

Questions/purposes: We therefore identified and quantified the risks associated with specific factors for peroneal nerve injury and recovery in patients with knee dislocations.

Outcomes of operative and nonoperative treatment of multiligament knee injuries: an evidence-based review.

Knee dislocation is an uncommon orthopedic diagnosis with a high rate of neurovascular complications. The goal of definitive management is to provide a pain free and functional knee through restoration of ligamentous stability and range of motion. Operative management has been suggested to be superior to nonoperative management for knee dislocations largely in part owing to a meta-analysis on the topic published a decade ago.

Diagnosis and management of knee dislocations.

An acute knee dislocation is an uncommon injury, with a high rate of associated vascular and neurologic injuries as well as potentially limb-threatening complications. High-energy trauma is the most common cause of an acute knee dislocation, although lower-energy injuries, such as those sustained during athletic competition, are increasing in incidence. Injuries to the popliteal artery and common peroneal nerve are relatively common, requiring a high index of suspicion and complete neurovascular examination in a timely fashion.
