An 18-year-old male subject was referred to our MRI scanning center, by an orthopedic surgeon, for a swelling over the plantar region of the foot. He had been in a motor vehicle accident a few weeks back, with no evidence of fracture at the time of injury. In subsequent weeks, he developed a swelling over his foot. MRI showed the presence of a fluid intensity lesion in the subdermal and dermal layers of his foot. Unguarded motor vehicle accidents often tend to cause severe injuries. Sometimes, they even need operative management since a motor vehicle collision is a high-impact accident...

BACKGROUND: Synovial fluid analysis is important in diagnosing prosthetic joint infection (PJI). The rate of culture-positive PJI in patients who have a dry tap of a total hip arthroplasty (THA) is not well described. METHODS: We reviewed all image-guided THA aspirations, performed from 2014 to 2021 at a single academic institution. Aspirations were categorized as successful (≥ 0.5 mL) or unsuccessful (< 0.5 mL, "dry tap"). We analyzed culture data on all repeat aspirations and revision surgeries performed within 90 days of the initial dry tap...

Lymphangioma, also known as cystic hygroma are benign malformations arising from abnormal development of the lymphatic system. Most often these lesions are found in the pediatric population, having a predilection for the neck/axilla, and are less common in extremities. Symptoms can vary based on size and location. Treatment is not usually indicated until they start impacting life due to deformity or symptoms such as pain, paraesthesia, etc. Here, we report a case report of lymphangioma located in the calf region of the right lower limb presenting in adult age...

MATERIALS AND METHODS:  The pathology reports from mid-March to mid-June 2019, 2020, and 2021 were retrospectively reviewed...

OBJECTIVE: To assess test-retest reliability and correlation of weight-bearing (WB) and non-weight-bearing (NWB) cone beam CT (CBCT) foot measurements and Foot Posture Index (FPI) MATERIALS AND METHODS: Twenty healthy participants (age 43.11±11.36, 15 males, 5 females) were CBCT-scanned in February 2019 on two separate days on one foot in both WB and NWB positions. Three radiology observers measured the navicular bone position. Plantar (ΔNAVplantar ) and medial navicular displacements (ΔNAVmedial ) were calculated as a measure of foot posture changes under loading...

Aligned pore structures present many advantages when conceiving biomaterial strategies for treatment of musculoskeletal disorders. Aligned ice templating (AIT) is one of the many different techniques capable of producing anisotropic porous scaffolds; its high versatility allows for the formation of structures with tunable pore sizes, as well as the use of many different materials. AIT has been found to yield improved compressive properties for bone tissue engineering, as well as higher tensile strength and optimized cellular alignment and proliferation in tendon and muscle repair applications...

One of the rarest causes of low back pain is septic arthritis of a lumbar facet joint. We report the case of a 92-year-old diabetic woman with a history of four days of back pain, dysuria, and fever. Due to a sudden worsening of lumbar pain, she went to the emergency department. Physical exam revealed pain with pressure over the D12 vertebral apophyses and the lower-left paraspinal musculature. Laboratory data showed a normochromic normocytic anemia with a hemoglobin of 9.3 g/dL, white cell count of 14.61x10e3/µL (83...

BACKGROUND: The use of vascularised fibula grafts is an accepted method for reconstructing the distal femur following resection of malignant childhood tumors. Limitations relate to the mismatch of the cross-sectional area of the transplanted fibula graft and the local bone, instability of the construct and union difficulties. We present midterm results of a unique staged technique-an immediate defect reconstruction using a double-barrel vascularised fibula graft set in in A-frame configuration and a subsequent intramedullary femoral lengthening...

Infective endocarditis (IE) is an infection of the heart valves or endocardium, usually due to the spread of infection through the blood. It can cause a varied range of symptoms, from being asymptomatic to reduced heart function, valvular abnormalities, embolization, or death. Enterococci are usually present as normal gut flora but can also cause bacteremia, urinary tract infections, or IE, especially in the elderly population. The source of enterococcal spread in most of the cases is unidentifiable and sometimes associated with the genitourinary tract or damage to the gut mucosa due to trauma, malignancy, and infection, among others...

INTRODUCTION: Access to public rehabilitation services for patients with non-urgent conditions - which suffer mainly from musculoskeletal disorders - is problematic around the world. Remote rehabilitation services are recognized as effective means to increase accessibility. Patient acceptability is an important element in the successful implementation of such clinical innovations and has not yet been studied thoroughly in this context. Thus, the aim of this study was to evaluate and compare the acceptability of two remote consultation modalities - phone and teleconsultation - for patients waiting for public outpatient non-urgent rehabilitation services...

AIMS: The aim of this study was to analyze the prevalence of culture-negative periprosthetic joint infections (PJIs) when adequate methods of culture are used, and to evaluate the outcome in patients who were treated with antibiotics for a culture-negative PJI compared with those in whom antibiotics were withheld. METHODS: A multicentre observational study was undertaken: 1,553 acute and 1,556 chronic PJIs, diagnosed between 2013 and 2018, were retrospectively analyzed...

Purpose: Aim of this retrospective cohort study was the comparison of the transiliac fixator (TIFI) and spinopelvic fixation (SPF) for fixation of dorsal pelvic ring fractures in terms of clinical outcome, complications, and quality of life. Methods: Thirty-eight patients (23 men, 15 women; mean age 47 ± 19 years) with dorsal pelvic ring fractures (type-C-injuries after AO/OTA) that have been stabilized by either TIFI (group TIFI, n = 22) or SPF (group SPF, n = 16) between May 2015 and December 2018 were retrospectively reviewed...

PET/MR is a promising hybrid imaging technique for evaluating musculoskeletal malignancies. Both technologies, independently are useful for evaluating this type of tumours. PET/MR has great potential combining metabolic and functional imaging PET with soft tissue contrast and multiparametric sequences of MR. In this paper we review the existing literature and discuss the different protocols, new available radiotracers to conclude with the scarce evidence available the most useful/probable indications of the PET MR for the for musculoskeletal malignancies...

Background Fascial plane blocks are a valuable and important aspect of patient care. However, nerve blocks sometimes present with a technical difficulty that can lead to upsetting the operating room schedule, cause discomfort to the patient, or lead to inadequate block. Potential predictors of this difficulty were evaluated. Methods In a single-blind study, ultrasound image quality was evaluated on a grading metric, and its correlation with several factors that could potentially impact the difficulty of a procedure, including age, BMI, weight, length of surgery, IV fluids, and pre- vs postoperative block, was assessed...

INTRODUCTION: Mountain running races have grown in popularity in the recent years. Nonetheless, there are few studies on injuries and injury rates. Moreover, these studies have focused on long-distance events such as ultramarathons (>42 km). Therefore, the aim of the present study was to examine the severity, type, and body location of musculoskeletal injuries during 20-42 km mountain running races. In addition, the injury rates in this type of races were examined. METHODS: Data on injuries were collected during 36 mountain running races over 5 consecutive seasons from 2015 to 2019...
