Use of a Modified Rep Model in Primary Joint Arthroplasty: Lessons Learned.

Orthopedic implant device sales representatives ("reps") can provide intraoperative guidance based on their product knowledge, as part of their many responsibilities. However, for experienced high-volume arthroplasty surgeons, a representative may not be required in the room for most primary total knee arthroplasty (TKA) procedures. The goal of this study was to describe the authors' experience with a modified rep model for primary TKA.

Piriformis-Sparing Technique in Total Hip Arthroplasty with Posterolateral Approach.

Introduction: Hip dislocation is a devastating complication after total hip arthroplasty (THA), which is slightly higher when using the traditional posterior approach. The piriformis tendon is the most important dynamic posterior stabilizing structure. The piriformis-sparing technique provides a reproducible method for THA, greatly reducing the dislocation rate.

Customized Knee Articulating Cement Spacer with Stem Extension for Treatment of Chronic Periprosthetic Joint Infection.

Introduction: Choice of articulating spacer in selected Methicillin-resistant Staphylococcus aureus (MRSA) patients with instability that do not qualify for a second-stage revision (i.e., due to significant co-morbidities, multiple persistent infections, open wound ulcers) is challenging.

Effect of Posterior Malleolus Fracture on Syndesmotic Reduction: A Cadaveric Study.

Background: Syndesmotic malreduction and fractures of the posterior malleolus negatively influence outcomes of rotational ankle fractures. Recent data have shown that posterior malleolus fixation contributes to the stability of the syndesmosis. The purpose of this study was to analyze syndesmotic reduction within the context of different sizes of posterior malleolus fracture fragments and different qualities of reduction.

Cadaveric Evaluation of Dorsal Intermetatarsal Approach for Plantar Plate and Lateral Collateral Ligament Repair of the Lesser Metatarsophalangeal Joints.

Background: Access to the plantar plate has been described using either a plantar approach or an extensive dorsal approach that required complete joint destabilization and often a metatarsal osteotomy. Clinical scenarios related to plantar plate tear vary and the pathologies in early stages are frequently limited to unilateral soft tissue structures; a less invasive operative approach may be possible. A novel approach requiring a release of only the lateral collateral ligament and the lateral half of the plantar plate is presented in this cadaver model; the extent of joint exposure possible is described.
