Osteotomies allow the restoration of appropriate sagittal alignment; however, closure of osteotomies can be challenging. Typical closure involves compressing pedicle screw heads across the rods, potentially causing screw loosening and failure. Motorized hinged operating tables are often used to assist with controlled closure of osteotomies without manual compression, but there is no published research

Approximately 1% of clinically treatable tyrosine kinase fusions, including anaplastic lymphoma kinase, neurotrophic tyrosine receptor kinase, RET proto-oncogene, and ROS proto-oncogene 1, have been identified in soft tissue sarcomas via comprehensive genome profiling based on DNA sequencing. Histologic tumor-specific fusion genes have been reported in approximately 20% of soft tissue sarcomas; however

Under Medicare's fee-for-service and bundled payment models, the basic unit of hospital payment for inpatient hospitalizations is determined by the Medicare Severity Diagnosis Related Group (MS-DRG) coding system. Primary total joint arthroplasties (hip and knee) are coded under MS-DRG code 469 for hospitalizations with a major complication or comorbidity and MS-DRG code 470 for those without a major

BACKGROUND Fungal prosthetic joint infections (PJIs) are rare yet severe events associated with high rates of recurrent infection. Although bacterial PJIs associated with megaprostheses are known to be associated with higher rates of recurrence and amputation, little is known about fungal PJIs near megaprostheses. QUESTIONS/PURPOSES In patients with fungal megaprosthesis PJIs from one institutional

BACKGROUND The Centers for Disease Control defines work-related musculoskeletal disorders as disorders of the nerves, muscles, tendons, joints, spinal discs, and cartilage that are caused or exacerbated by the environment or nature of work. Previous meta-analyses have characterized work-related musculoskeletal disorders among interventionists, general surgeons, and other surgical subspecialties, but

BACKGROUND The distribution of subchondral bone density in a joint represents stress that is applied to the joint. Knowing this information is important for understanding the pathophysiology of osteoarthritis (OA). In the elbow, however, this has not been studied before. QUESTIONS/PURPOSES (1) Is advanced-stage elbow OA associated with more radially distributed subchondral bone density than earlier

BACKGROUND Robotic-assisted TKA continues to see wider clinical use, despite limited knowledge of its impact on patient satisfaction and implant survival. Most studies to date have presented small cohorts and came from single-surgeon or single-center experiences. Therefore, a population-level comparison of revision rates between robotic-assisted and conventional TKA in the registry setting may help

In-office procedures can be painful and anxiety-provoking for pediatric patients. Minimizing such pain and anxiety in children improves the patient experience and promotes a rewarding and productive patient-caregiver-provider relationship, which may for some young patients be their first memorable encounter with the healthcare system. Although virtual reality (VR) techniques have proven to be helpful

Chronic ankle instability is a common sports injury that often presents with increased plantarflexion and restricted dorsiflexion. The cumulative effect of peripheral injuries may induce neuroplasticity in the central nervous system. However, the relationship between dorsiflexion or plantarflexion and the central nervous system in patients with chronic ankle instability remains unknown.

BACKGROUND Replantation is an established treatment for traumatic upper extremity amputation. Only a few studies, however, have assessed the patient-reported outcomes of replantation, and the findings of these studies have been conflicting. QUESTIONS/PURPOSES (1) Is replantation associated with better hand function than revision amputation? (2) Is replantation associated with better health-related

Performing THA in patients with high-riding developmental dysplasia of the hip (DDH) is associated with serious complications and technical challenges. Various methods of shortening osteotomy are available to facilitate femoral head reduction during THA in patients with high-riding hips; subtrochanteric shortening osteotomy and trochanteric slide osteotomy plus proximal shortening are the most common

The diagnosis of periprosthetic joint infection (PJI) is a major challenge in clinical practice. The role of neutrophils in fighting infection has been increasingly understood, and one mechanism of action of these cells is neutrophil extracellular traps. However, little is known about this process in PJI.

Geographically based social determinants of health (SDoH) measures are useful in research and policy aimed at addressing health disparities. In the United States, the Area Deprivation Index (ADI), Neighborhood Stress Score (NSS), and Social Vulnerability Index (SVI) are frequently used, but often without a clear reason as to why one is chosen over another. There is limited evidence about how strongly

BACKGROUND Robust physical mobility is the key to healthy independent aging. Although the association between socioeconomic status and health is well documented, it is unclear whether there is a relationship between mobility and income, because income data are not readily available. QUESTIONS/PURPOSES (1) Do individuals with better mobility have higher incomes? (2) Does maintaining mobility over time

BACKGROUND Proximal humeral fractures (PHFs) often occur in elderly individuals who experience low-energy falls. Open reduction and internal fixation (ORIF) of the proximal humerus is typically performed in young, active patients because of their good bone quality and high functional demands. Although good short-term results have been reported after ORIF in young patients, few studies have specifically

Conversion THA, which we defined for this study as THA with concomitant removal of preexisting orthopaedic hardware, has been associated with increased hospital costs and perioperative complications compared with primary THA. Yet, conversion THA is classified as a primary procedure under the Medicare Severity Diagnosis-Related Group coding scheme, and hospitals are reimbursed based on the resource

Positive intraoperative cultures (PICs) are encountered in some patients undergoing revision of the acetabular cup after a previous THA. It is unknown whether PIC of the cup indicates whether the stem is infected as well and what happens to the stem during follow-up.

Obesity-based cutoffs in TKA are premised on higher rates of postoperative complications. However, operative time may be associated with postoperative complications, leading to an unnecessary restriction of TKA in patients with obesity. If operative time is associated with these obesity-related outcomes, it should be accounted for in order to ensure all measurable factors associated with negative outcomes

Demand for platelet-rich plasma (PRP) injections for osteoarthritis has dramatically increased in recent years despite conflicting evidence regarding its efficacy and highly variable pricing in the top orthopaedic centers in the United States, because PRP is typically not covered by insurance. A previous study investigating the mean price of PRP injections obtained information only from centers advertising

Patients undergoing massive tumor resection and total femur replacement (TFR) face a substantial risk of hip dislocation and infection, often resulting in multiple implant revisions or hip disarticulation. These complications can impact their independence and prognosis. Additionally, their shorter life expectancy is influenced by challenges in achieving local radical resection and controlling metastases

When evaluating the results of clinical research studies, readers need to know that patients perceive effect sizes, not p values. Knowing the minimum clinically important difference (MCID) and the patient-acceptable symptom state (PASS) threshold for patient-reported outcome measures helps us to ascertain whether our interventions result in improvements that are large enough for patients to care about

Dental procedures can lead to bacteremia and have been considered a potential risk factor for pyogenic vertebral osteomyelitis (PVO). However, data on the association between dental procedures and PVO are limited.

Liposarcoma is the most commonly diagnosed subtype of soft tissue sarcoma. As these tumors often arise near vital organs and neurovascular structures, complete resection can be challenging; consequently, recurrence rates are high. Additionally, available chemotherapeutic agents have shown limited benefit and substantial toxicities. There is, therefore, a clear and unmet need for novel therapeutics

BACKGROUND The Patient-Reported Outcomes Measurement Information System® (PROMIS®) may be used to assess an individual patient's perspective of their physical, mental, and social health through either standard or computer adaptive testing (CAT) patient questionnaires. These questionnaires are used across disciplines; however, they have seen considerable application in orthopaedic surgery. Patient characteristics

BACKGROUND No single graft type has been shown to have a benefit in acetabular labral reconstruction. The native labrum and lateral meniscus share many similarities, suggesting that the meniscus may be a promising source of graft material in labral reconstruction. QUESTIONS/PURPOSES Using a pig model, we sought to evaluate the healing process of fresh-frozen meniscus allograft for acetabular reconstruction

BACKGROUND Lag screw cutout is a devastating complication after internal fixation of an intertrochanteric fracture. Although the tip-apex distance (TAD) is known to be associated with this complication, another factor we thought was potentially important-fracture reduction on an oblique lateral view-has not, to our knowledge, been explored. QUESTIONS/PURPOSES (1) Is a well-reduced fracture position

BACKGROUND In the setting of a suspected scaphoid fracture, MRI may result in overdiagnosis and potential overtreatment. This is in part because of the low prevalence of true fractures among suspected fractures, but also because of potentially misleading variations in signal that may be more common than fracture-related signal changes. To better understand the risk of overdiagnosis, we first need insight
