OBJECTIVES: Preoperative CT scans of articular fractures can be invaluable, but can also impart a radiation burden on the population. The goal of this study is to determine if a substantially lowered radiation protocol would provide satisfactory information for the surgeon, using the distal tibia as a model. METHODS: 11 adult cadaveric distal tibia specimens were utilized to create AO/OTA 43C distal tibia fractures with varying displacements in 2 planes. Each specimen was scanned at 3 modified protocols, which were then subsequently read by both qualified attending orthopedists and mid-level residents...

Bone disorders are a group of varied acute and chronic traumatic, degenerative, malignant or congenital conditions affecting the musculoskeletal system. They are prevalent in society and, with an ageing population, the incidence and impact on the population's health is growing. Severe persisting pain and limited mobility are the major symptoms of the disorder that impair the quality of life in affected patients. Current therapies only partially treat the disorders, offering management of symptoms, or temporary replacement with inert materials...

Awareness of rare etiologies for implant failure is becoming increasingly important. In addition to the overall increase in joint arthroplasties, revision surgeries are projected to increase dramatically in the coming years, with volume increasing up to seven-fold between 2005 and 2030. The literature regarding the relationship between metal allergy and implant failure is controversial. It has proven difficult to determine whether sensitization is a cause or a consequence of implant failure. Testing patients with functional implants is not a clinically useful approach, as the rate of hypersensitivity is higher in implant recipients than in the general population, regardless of the status of the implant...

BACKGROUND: Despite the excellent outcomes associated with primary total hip arthroplasty (THA), implant failure and revision continues to burden the healthcare system. THA failure has evolved and displays variability throughout the literature. In order to understand how THAs are failing and how to reduce this burden, it is essential to assess modes of implant failure on a large scale. Thus, we report: (1) etiologies for revision THA; (2) frequencies of revision THA procedures; (3) patient demographics, payor type, and US Census region of revision THA patients; and (4) the length of stay and total costs based on the type of revision THA procedure...

OBJECTIVE: "Lisfranc joint injury" is comprised of a tarsometatarsal joint-complex injury. The Lisfranc complex injury is always a challenge for orthopedists, and the optimum treatment is still up for debate. Anatomic reduction and stable internal fixation prove to have no satisfactory outcomes. This research aims to compare the clinical curative effects, complications and radiographic features of arthrodesis and non-fusion of the Lisfranc joint in the follow-up of the patients who suffered Lisfranc injuries...

The iliotibial tract, also known as Maissiat's band or the iliotibial band, and its associated muscles function to extend, abduct, and laterally rotate the hip, as well as aid in the stabilization of the knee. A select group of associated injuries and pathologies of the iliotibial tract are seen as sequela of repetitive stress and direct trauma. This article intends to educate the radiologist, orthopedist, and other clinicians about iliotibial tract anatomy and function and the clinical presentation, pathophysiology, and imaging findings of associated pathologies...

INTRODUCTION: The diagnosis of lumbar hernia can be easily missed, as it is a rare case to which most orthopedists are not exposed in their common clinical practice. Approximately 300 cases have been reported in the literature since it was first described by Barbette in 1672. CASE PRESENTATION: A 76-year-old woman who had been diagnosed with a femoral intertrochanteric fracture was sent to our department. Physical examination revealed a smooth, soft, and movable mass, with no tenderness, palpable on her left flank, which had gradually increased during the last seven years and presented with a slight feeling of swelling...

OBJECTIVE: To determine whether training on shoulder and elbow surgery influences the orthopedist surgeons' preferred technique to address acute acromioclavicular joint dislocation (ACD). METHODS: A survey was conducted with shoulder and elbow specialists and general orthopedists on their preferred technique to address acute ACD. RESULTS: Thirty specialists and forty-five general orthopedists joined the study. Most specialists preferred the endobutton technique, while most general orthopedists preferred the modified Phemister procedure for coracoclavicular ligament repair using anchors...

INTRODUCTION: Diagnosis of axial spondyloarthritis (SpA) can be delayed for several years mainly because of low awareness of axial SpA among non-rheumatologists who are the first interlocutors of potential SpA patients. One strategy to decrease the delay between appearance of first symptoms and diagnosis of axial SpA and to allow early management of the disease is to provide the non-rheumatologists with tools to identify patients requiring prompt referral to rheumatologists. This study was designed to evaluate in a real-world setting whether screening patients with chronic low back pain who consult physical medicine and rehabilitation (PMR) physicians, orthopedists, and ophthalmologists is useful in detecting axial SpA...

The use of musculoskeletal allografts by orthopedic surgeons continues to rise. The process of procuring and sterilizing allografts is evolving with much consideration to limiting the spread of infectious diseases and preserving tissue integrity. Research involving the application of allografts, particularly for ligament repair, is quite active, necessitating an update for the practicing orthopedist. Avoiding donor site morbidities is one of the most commonly cited advantages of allografts over autografts. There is controversy amongst studies for allografts in terms of their biological incorporation and clinical outcomes compared to autografts...

Intra-articular hip injections have proven clinical value for both diagnostic and therapeutic purposes. Historically, these injections have been performed by radiologists using fluoroscopic guidance. This necessitates a radiology referral, delays the injection, and represents lost productivity for the orthopedist. Ultrasound-guided intra-articular hip injections have been described in the radiology literature with excellent accuracy. These injections were performed by radiologists. The purpose of this study was to determine the accuracy of ultrasound-guided hip injections performed in the orthopedic clinic by orthopedic surgeons and orthopedic physician assistants...

INTRODUCTION: The appearance of patellofemoral pain after a knee arthroplasty, particularly in rheumatic diseases, resulted in the incorporation of the substitution of the patellar component in all designs. The replacement of the patella became a standard part of knee arthroplasty, but the controversy over whether to restore it or not continues among orthopedists that perform knee arthroplasties. OBJECTIVE: To analyze the incidence of anterior knee pain in patients who underwent primary knee arthroplasty with or without replacement of the patellar component...
