Acquired : Current Concepts - "From Adult Acquired to Progressive Collapsing Foot Deformity".

The clinical disorder traditionally known as or has been the subject of several publications over the past two decades. Now, it is understood that the problem does not lie in the posterior tibial tendon per se and may even occur without tendon injury. Studies have brought new concepts and understanding that question the views on this subject, culminating in the replacement of existing classifications with one that is more assertive and discriminative of the potential presentation patterns of the deformity.

Quantification of First Metatarsal Joint Surface Interactions in Hallux Rigidus Using Distance and Coverage Mapping: A Case-Control Study.

Background: Weightbearing cone-beam computed tomography (WBCT) has proven useful for analysis of structural changes of the foot and ankle when compared to conventional radiographs. WBCT allows for extraction of distance and coverage mapping metrics, which may provide novel insight into hallux rigidus (HR). This study retrospectively assessed HR joint space using distance and coverage mapping in a case-control study.

The impact of prior authorization review on orthopaedic subspecialty care: a prospective multicenter analysis.

Background: Prior authorization review (PAR), in the United States, is a process that was initially intended to focus on hospital admissions and costly high-acuity care. Over time, payors have broadened the scope of PAR to include imaging studies, prescriptions, and routine treatment. The potential detrimental effect of PAR on health care has recently been brought into the limelight, but its impact on orthopedic subspecialty care remains unclear.

High Prevalence of Work-related Musculoskeletal Disorders and Limited Evidence-based Ergonomics in Orthopaedic Surgery: A Systematic Review.

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 prevalence estimates, prognosis, and ergonomic considerations vary by study and surgical specialty.

Questions/purposes: (1) What is the career prevalence of work-related musculoskeletal disorders in orthopaedic surgeons? (2) What is the treatment prevalence associated with work-related musculoskeletal disorders in orthopaedic surgeons? (3) What is the disability burden of work-related musculoskeletal disorders in orthopaedic surgeons? (4) What is the scope of orthopaedic surgical ergonomic assessments and interventions?

Methods: A systematic review of English-language studies from PubMed, MEDLINE, Embase, and Scopus was performed in December 2022 and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Computer Simulated Enhancement and Planning, Robotics and Navigation With Patient Specific Implants and 3-D Printed Cages.

Study Design: This is a retrospective cohort study.

Objectives: Pre and postop Measurement Testing. This is a retrospective study of 33 consecutive interbody spacers in 21 patients who underwent pre, intra, and postoperative measurement of the middle column to determine if this would lead to more precise restoration of middle column height and spacer fit.

Postoperative Rehabilitation of Multidirectional Instability Surgery: A Systematic Review.

Multidirectional instability (MDI) of the shoulder is managed with surgery when conservative rehabilitation fails. The optimal postsurgical management of MDI is not well understood. The purpose of this study is to create a systematic review evaluating postsurgical rehabilitation protocols treating MDI.

Unplanned Resection of Sarcoma.

Unplanned resection is a common problem in the management of sarcoma. Because sarcomas are so rare, they may be misdiagnosed initially as more common benign lesions. When the treating surgeon is unaware of or does not adhere to proper surgical principles of orthopaedic oncology, an intralesional procedure may be performed without the requisite preoperative imaging, staging, or wide resection margins for optimal management of sarcoma.
