Pisiform Ligament Complex Syndrome

Injuries and disorders of the pisiform and pisotriquetral joint manifest as palmar, ulnar-sided wrist pain. They encompass a wide range of conditions that are grouped under the term pisiform ligament complex syndrome. The diagnosis and treatment of these conditions vary according to the underlying etiology. This review discusses the wide spectrum of pathologies related to the pisiform and pisotriquetral joint and the treatments for these conditions.

Use of Reverse Shoulder Arthroplasty for Proximal Humerus Fractures: Technique and Pearls

The treatment of complex fractures of the proximal humerus in elderly patients continues to evolve. For fractures that require surgery, the popularity of reverse shoulder arthroplasty as a treatment option continues to grow. Techniques that emphasize repair of the greater tuberosity have facilitated reliable outcomes for these challenging fractures.

Intraoperative Neuromonitoring in Spine Surgery

Intraoperative neuromonitoring is used frequently during spine surgery to provide the surgeon with real-time identification of potential neurologic insults, permitting immediate interventions that can reduce iatrogenic injuries. Somatosensory-evoked potentials, motor-evoked potentials, and electromyography are discrete neuromonitoring modalities used to evaluate separate portions of the nervous system. Understanding of neuroanatomy and the basic principles associated with each modality is crucial for maximizing the efficacy of intraoperative neuromonitoring in spine surgery. In this article, we describe the different modalities of intraoperative neuromonitoring, explain the basic principles of each, and provide examples of its utility in spine surgery.
