Background: Proximal femoral varus osteotomy (PFVO) is commonly performed to improve femoral head containment and decrease deformity in Legg-Calve-Perthes disease (LCPD). Little is known about how PFVO impacts the quality of life after surgery. The purpose of this study was to determine the longitudinal changes to patient-reported physical, mental, and social health measures after PFVO.

Introduction: The number of reverse shoulder arthroplasties (RSA) performed each year is growing rapidly, especially in elderly patients and with expanded indications including geriatric proximal humerus fractures. As the elderly population grows and the number of RSA's annually continues to rise, there will be a proportionate number of adverse events and mortality. However, the rate of early mortality has consistently shown to be less than 1%, so a large-scale analysis of possible risk factors for post-operative mortality is warranted.

Objectives: The rising popularity of reverse total shoulder arthroplasties (RTSA) demands attention to its growing costs on the healthcare system, especially with the implementation of bundled payments. Charges associated with patients' inpatient stays can be mitigated with a better understanding of the drivers of cost following RTSA. In this study, we evaluate potential pre-operative and post-operative factors associated with higher inpatient costs following RTSA.

Introduction: The annual utilization of reverse total shoulder arthroplasty (RTSA) and anatomic total shoulder arthroplasty (ATSA) has grown exponentially, in part due to the expanded indications of RTSA. This evolution in shoulder arthroplasty prompts the need to evaluate outcomes between ATSA and RTSA. However, many other studies comparing outcomes between ATSA and RTSA lacked a large nationally-represented sample, a matched cohort analysis, or both.

Purpose: Multiple procedures have been described for wrist and finger flexion contractures and spasticity. Fractional lengthening of forearm flexor tendons involves making parallel transverse tenotomies at the musculotendinous junction to elongate the muscle. Currently, there is limited literature to define the biomechanical consequences of this lengthening technique.

Introduction: With innovations in transplant medicine and longer life expectancies in solid organ transplant (SOT) recipients, the incidence of shoulder arthroplasty is predictably rising in this population. Reverse shoulder arthroplasty (RSA) has become increasingly popular due to advances in prosthetic design with expanded indications. While previous studies have examined shoulder arthroplasty in SOT patients, information specifically related to RSA patients is largely unexplored.

Purpose: Proximal interphalangeal (PIP) joint arthrodesis is a procedure employed to address arthritis, instability, and deformity. Multiple fixation methods are available to maintain stability across the arthrodesis interval, including headless compression screws (HCSs), tension band wiring (TBW), plating, and Kirschner wire constructs. The purpose of this study was to compare the biomechanical properties of the HCS and TBW techniques.

Carpal dislocations.

J Hand Surg Eur Vol

Article Synopsis
  • Carpal dislocations happen when the bones and ligaments in the wrist are disrupted, often due to predictable injury mechanisms that are important for diagnosis and treatment.
  • Lunate dislocations are the most frequent type, but other carpal bones can also become dislocated separately.
  • The standard treatment is open reduction and internal fixation, though these injuries can still lead to long-term complications even if treated correctly and quickly.*

Background: There is no consensus on whether unicompartmental arthroplasty (UKA) or high tibial osteotomy (HTO) is superior for unicompartmental arthritis. While there are studies comparing revision and complication rates, none matched a large number of patients undergoing HTO and UKA in the United States and compared these outcomes. We investigated TKA conversion rate and the complications following HTO or UKA.

This review article examines contemporary methods and assesses radiographic outcomes and postoperative complications following the modified Lapidus procedure. A systematic review demonstrated significant improvements in intermetatarsal angle, hallux valgus angle, and tibial sesamoid position. We are updating a modified Lapidus technique for achieving triplanar correction of hallux valgus.

Background: Perthes disease most commonly affects children 5 to 7 years old, and nonoperative management, such as weightbearing and activity restrictions, is generally recommended. In earlier research in children aged 8 to 14 years who had Perthes disease, we found that the restrictions were associated with worse mobility, but mental health or social health measures were not linked. However, Perthes disease most commonly affects children 5 to 7 years old who are more emotionally and cognitively immature.

The purpose of this study is to investigate the potential benefit of using prolonged non-weightbearing (PNWB) as a treatment option for early-stage Legg-Calvé-Perthes disease (LCPD). An Institutional Review Board (IRB) approved this retrospective study of patients with LCPD and ≥2-year follow-up. Patients 6-12 years of age were included if treatment began in Waldenstrom stage 1 or 2A.

Background: Weightbearing and activity restrictions are commonly prescribed during the active stages of Perthes disease. These restrictions, ranging from cast or brace treatment with nonweightbearing to full weightbearing with activity restrictions, may have a substantial influence on the physical, mental, and social health of a child. However, their impact on the patient's quality of life is not well-described.

Article Synopsis
  • - Thiol-ene/acrylate shape-memory polymers are being explored as suitable materials for neural electrodes that help treat neurological disorders by influencing nerve impulse conduction.
  • - The study focuses on identifying the best synthesis methods for these polymers, considering factors like curing conditions, polymer thickness, monomer ratios, and water absorption to achieve optimal properties.
  • - Results indicate that polymers with a minimum of 50% acrylate content and cured for at least 1 hour at a wavelength of 365 nm show great potential for use as neural electrode substrates due to their favorable characteristics.
