Safety information in spine surgery is important for informed patient choice and performance-based payment incentives, but measurement methods for surgical safety assessment are not standardized. Published reports of complication rates for common spinal procedures show wide variation. Factors influencing variation may include differences in safety ascertainment methods and procedure types. ⋯ The observed frequency of adverse events is influenced by the ascertainment modality. Voluntary reports by surgeons and other team members missed more than 50% of the events identified through a medical records review. Increased surgery invasiveness, measured from medical records or billing codes, is quantitatively associated with an increased risk of adverse events.

Iatrogenic nerve injuries frequently occur during procedures around the hand and wrist, although they are not always recognized at the time of injury or in the immediate postoperative period. Because preventing injuries is of paramount importance, extensive knowledge of the anatomy of the at-risk nerves is critical. Best results occur after immediate repair because a substantial delay before secondary surgery diminishes the chances for recovery from motor or sensory nerve dysfunction and relief from pain. It is helpful to review iatrogenic nerve injuries associated with common hand surgical procedures.

Biologic and synthetic scaffolds, mechanical loads, vitamin D, and diabetes can affect tendon and tendon-to-bone healing, muscle recovery, and growth in the perioperative period. Despite important advances in technical approaches to achieve surgical repair of soft tissues in a minimally invasive fashion, structural healing after tendon-to-bone repair remains a formidable challenge that is complicated by our incomplete knowledge of complex natural biologic processes and a diverse patient population with various comorbidities and deficiencies. ⋯ Augmentation with scaffolds may reinforce the initial repair biomechanically and can be coupled with growth factors to promote a favorable biologic environment for healing. Careful consideration of the implications of postoperative rehabilitation and endocrine and nutritional deficiencies on structural healing and muscle recovery are also critical to optimize patient outcomes.

Volar locking plates have provided surgeons with enhanced capability to reliably repair both simple and complex fractures and avoid the hardware-related complications associated with dorsal plating. However, there have been an increasing number of published reports on the frequency and types of complications and failures associated with volar locked plating of distal radius fractures. An informed, critical assessment of distal radius fracture characteristics will allow surgeons to select an individualized treatment strategy that maximizes the likelihood of a successful outcome. Knowledge of the anatomy, patterns, and characteristics of the diverse types of distal radius fractures and the complications and failures associated with volar locked plating will be helpful to orthopaedic surgeons who treat patients with these injuries.

Pediatric musculoskeletal infections can cause devastating complications (including death) in this era of methicillin-resistant Staphylococcus aureus and other virulent bacterial strains. The complexity and severity of these infections require timely diagnosis and treatment. A thorough emergency department evaluation, diagnostic workup, and early surgical intervention can influence outcomes. ⋯ Because of genetic changes and inducible resistance, methicillin-resistant Staphylococcus aureus causes more complex infections than in the past. Deep, soft-tissue abscesses; pyomyositis; osteomyelitis; and septic arthritis often occur concurrently, causing destruction of musculoskeletal tissue. Severe and life-threatening complications, such as septic emboli, deep venous thrombosis, and multiorgan system failure may result from these infections.
