Ischiofemoral Impingement Due to an Undiagnosed Pelvic Avulsion Fracture.

ABSTRACT: Ischial tuberosity (IT) avulsion fractures are an uncommon cause of injuries in athletes. In this case, a 26-year-old female suffering from posterior right hip pain for over a decade presented with debility and a decrease in athletic function. Notable history included a hamstring strain while sprinting in elementary school. Clinical examination suggested hamstring tendinopathy and ischiofemoral impingement (IFI). Magnetic resonance imaging (MRI) revealed a chronic, fragmented, IT apophyseal avulsion fracture with ischial bursitis and edema within the fragmented bone, suggesting the development of heterotopic ossification (HO). Diagnostic ultrasound revealed signs of IFI, not evident on MRI. Ultrasound-guided corticosteroid injection in her ischial bursa and ischiofemoral space provided complete relief. The patient was able to resume her activities of daily living and sports-related activities without pain. Although interventional treatments may provide temporary pain relief, a multimodal approach is required for the treatment of HO.

Heterotopic Mineralization of the Medial Collateral Ligament: Our Experience Treating Two Cases of Calcific Versus Ossific Lesions With Ultrasonic Vacuum Debridement.

Chronic injury to the medial collateral ligament (MCL) is common following an acute knee injury. This case report presents two patients that failed to respond to conservative treatment with clinical evidence of an MCL injury and radiographic finding of a benign-appearing soft tissue lesion in the MCL. Calcified or ossified lesions have been described with chronic MCL injuries. Ossification and calcification of the MCL have been observed as potential causes of chronic MCL pain. Here, we detail the distinction between these two distinct intra-ligamentous heterotopic deposits and describe a novel treatment approach using ultrasonic percutaneous debridement, a technique that is typically reserved for tendinopathies. In both cases, pain improved, and they were able to return to their prior level of function.

A Hybrid Musculoskeletal Ultrasound Curriculum for Physical Medicine and Rehabilitation Residents-a Multi-center Pilot Program.

Purpose of Review: The increased use of musculoskeletal ultrasound (MSKUS) in clinical practice warrants achieving competency earlier in physiatrists' careers. Physical Medicine and Rehabilitation (PM&R) residency programs have started incorporating formal MSKUS training in their curricula; however, significant heterogeneity remains in MSKUS education. Recent Findings: Numerous barriers contribute to the lack of consensus for MSKUS training during residency, but the COVID-19 pandemic severely disrupted in-person learning. As an adjunct or alternative to in-person learning, teleguided technology is being utilized. Summary: This curriculum demonstrates the role of a hybrid MSKUS training with interinstitutional collaboration. Twenty PM&R learners, from two institutions, were divided into a fundamental or advanced track. Virtual didactic sessions alternated weekly with hands-on ultrasonographic scanning sessions. Following a 12-month longitudinal curriculum, an end-of-year practical examination was used for competency assessment, in addition to a survey assessing resident perceptions and feedback. To our knowledge, this is the first collaborative and hybrid MSKUS curriculum for PM&R learners that can be easily reproduced at most training institutions and circumvent some of the barriers amplified by the COVID-19 pandemic.

Prone Lachman with Ultrasound: A Literature Review and Description of the Technique.

ABSTRACT: Magnetic resonance imaging is the current gold standard imaging modality for diagnosing anterior cruciate ligament (ACL) tears. However, ultrasound has grown in popularity for detecting ACL injuries because of its low cost, portability, and dynamic assessment capabilities. Recent studies demonstrate high sensitivity and specificity for diagnosing isolated ACL tears via ultrasound, but tremendous heterogeneity remains for optimal technique including patient positioning, transducer placement, and dynamic versus static ultrasound usage. As ultrasound becomes ubiquitous in clinics, training rooms, and on the sidelines, identifying objective and sensitive measurements to appropriately screen athletes for significant knee injuries is imperative. This article aims to review the current role of diagnostic ultrasound in ACL injuries and propose a standardized version of the Prone Lachman with Ultrasound test, which is an objective, reliable, and easily reproducible technique to evaluate ACL competency. Developing a standardized protocol will expand the use of point-of-care ultrasound, which may reduce cost and improve efficiency in care.

Musculoskeletal Ultrasound as a Motivator for Selecting a Physical Medicine and Rehabilitation Residency Program in the United States: A Multicenter Survey Study.

ABSTRACT: This study aimed to determine the influence of musculoskeletal ultrasound (MSKUS) curriculum on applicants during the residency-selection process. A survey of 666 applicants for the Johns Hopkins University, Mayo Clinic, and Harvard/Spaulding Rehabilitation Physical Medicine and Rehabilitation programs was conducted in June 2020. A total of 180 respondents scored the influence of a MSKUS curriculum on their decision making for residency selection. In addition, applicants were asked to rank specific areas of physical medicine and rehabilitation that influenced their decision making. Participants most commonly included MSKUS in their top three areas of interest when constructing their rank order list. When asked whether MSKUS presence within a program had an effect during the interview-selection process, 71% responded with "very important" or "absolutely essential" (P < 0.001). For 74% of applicants, exposure to MSKUS in residency was an important factor when creating their rank order list (P < 0.001). More than 92% of applicants stated that they are "likely" or "very likely" to use MSKUS in their future practice and 83% would recommend a program with MSKUS to future candidates (P < 0.001). Based on these results, a large percentage of physical medicine and rehabilitation applicants intend on using MSKUS in their future practice. Therefore, MSKUS may be an important factor for residency selection.

The Effect of Age and Competition Level on Subtle Motor Performance in Adolescents Medically Cleared Postconcussion: Preliminary Findings.

OBJECTIVE: The aim of this study was to examine the effect of age and level of competition on subtle motor performance in adolescents who have recently been medically cleared postconcussion and never-injured controls. DESIGN: Thirty adolescents who were recently medically cleared postconcussion (12-18 yrs) and 30 never-concussed, typically developing controls were examined using the Revised Physical and Neurological Examination of Subtle Signs (PANESS) and the Immediate Post-Concussion Assessment and Cognitive Testing. RESULTS: Older age was associated with better Immediate Post-Concussion Assessment and Cognitive Testing scores in both groups, whereas only the control group showed improved motor performance on the PANESS with increasing age. Adolescents across both groups participating at a higher level of competition (school or travel level) had better motor performance on the PANESS than those participating at a lower level of competition (recreational level or no sports participation). Adolescents medically cleared postconcussion had greater motor deficits on the PANESS than controls did. CONCLUSION: After medical clearance, adolescents with a history of recent concussion demonstrate alterations in the relationship between motor function and age. The PANESS merits further exploration as a measure that is sensitive to factors affecting motor performance, such as age and level of athletic competition, as well as to persistent subtle motor deficits in adolescents medically cleared postconcussion.
