Nerve Transfers in the Management of Femoral Nerve Palsy: A Systematic Review.

ABSTRACT: The primary objective of this systematic review is to describe the effectiveness of nerve transfers for restoring quadriceps motor function in patients with femoral nerve palsy. MEDLINE, EMBASE and CENTRAL were searched from their inception to June 2023 for any English language, primary literature investigating nerve transfers for femoral nerve palsy. Data was extracted for study and intervention characteristics, and clinical outcomes, including preoperative and postoperative knee extension strength, electrodiagnostic studies, functional outcomes, adverse events and donor site morbidity. The primary outcome was defined as return of knee extension equivalent to or greater than a grade 4- on the Medical Research Council scale. Eighteen studies with a total of 40 patients were included. The most common nerve donor was the obturator nerve in 17 studies with 37 patients, followed by the nerve to sartorius in two studies (10 patients). Significant variations in procedures and outcomes reported were observed. There were no studies that reported an effect on ambulation due to donor weakness. Based on the available literature, nerve transfer appears to be an effective treatment for restoring quadriceps function in this population, with 79% of patients in our study achieving at minimum 4-/5 MRC grade power.

Upper Limb Casting Application Post-Botulinum Toxin Injection for Elbow Spasticity: A Guided Casting Protocol.

ABSTRACT: Casting is an effective adjunctive treatment, which increases the effects of botulinum toxin on patients with spasticity. The evidence for casting as an adjunctive therapy post-botulinum toxin has been well documented in the literature. However, standardized casting protocols are lacking, with no published descriptions of upper limb casting application post-botulinum toxin injection for spasticity. In this article, we will describe our experience regarding the application of upper limb casting as an adjunctive therapy for elbow spasticity, detailing indications, contraindications, and description of our protocol (materials required and technique).

Electrodiagnostic reporting preferences of referring physicians: An exploratory survey.

INTRODUCTION/AIMS: Electrodiagnostic (EDX) studies play a crucial role in the evaluation of patients with peripheral nervous system disorders. Accurate and succinct communication of test results is critical to patient safety and clinical decision-making. The objective of this study was to explore EDX reporting preferences of referring physicians to improve quality of communication and patient care. METHODS: An online survey was developed, and a purposive sampling strategy was used to recruit physicians in the authors' professional networks. Quantitative and qualitative survey data underwent frequency and thematic analyses, respectively. RESULTS: There were 40 respondents, including: 21 non-surgical specialists, 12 surgical specialists, and 7 family physicians. Sections rated as most critical were diagnostic impression (97%) and summary/interpretation (72%). Only 18% reported numeric data as critical to their needs, preferring this data to be formatted as bullet points or tables without nerve conduction study waveforms. Regarding the format of the data summary and diagnostic impression sections, the majority of respondents preferred bullet points rather than paragraphs. DISCUSSION: The results of this exploratory survey suggest that physicians who refer patients for EDX studies prefer reports that emphasize the interpretation of EDX data and a clear diagnostic impression, particularly in bullet point format. This project highlights important preferences and how they compare to recommended reporting guidelines, which may help improve communication and ultimately patient care. Future efforts should explore larger sample sizes with all key stakeholders in the EDX process to better understand reporting styles and preferences with greater nuance and context.

Fibularis Intersection Syndrome: A Rare Cause of Lateral Foot Pain in Runners.

ABSTRACT: Running is a common cause of foot and ankle injuries. Accurate diagnosis is important for appropriate management to resolve the issue. For clarity of diagnoses, the physician should be able to perform a thorough physical examination in conjunction with point-of-care ultrasound. The authors report a case study of a young male runner with lateral ankle pain. Based on clinical assessment and point-of-care ultrasound, a diagnosis of fibularis intersection syndrome was proposed. This type of injury can be treated with graded eccentric loading of fibularis tendons and proprioceptive exercises. This case report highlights the importance of point-of-care ultrasound to determine the appropriate diagnosis and management.

Effect of treating elbow flexor spasticity with botulinum toxin injection and adjunctive casting on hemiparetic gait parameters: A prospective case series.

OBJECTIVE: To investigate changes in hemiparetic gait parameters after treatment of elbow flexor spasticity with botulinum neurotoxin (BoNT) injection and adjunctive casting. DESIGN: Prospective case series. SUBJECTS: Ten participants with spasticity secondary to acquired brain injury (8 stroke, 2 traumatic brain injury). INTERVENTIONS: Participants received BoNT injections for their spastic elbow flexors under ultrasound guid-ance. Two weeks post-injection, an elbow stretching cast was applied for 1 week. OUTCOME MEASURES: Assessments using the Modified Ashworth Scale (MAS), Tardieu scale V1 angle of arrest at slow speed and V3 angle of catch at fast speed, 2-min walk test (2MWT), Edinburgh Gait Score scale (EGS) and video gait analysis for step-length symmetry were conducted pre-BoNT injection (t0) and at cast removal (t1). Goal attainment scale (GAS) was used to assess changes in spasticity and gait 3 months post-injection (t2). RESULTS: At t1, participants showed a mean increase of 16.7° (p < 0.01) on the Tardieu Scale V3 and a mean reduction of 0.5 points on the MAS (p < 0.05). There was also a mean reduction on EGS of 2.7 points (p < 0.05), and a mean increase on 2MWT of 3.1 m (p < 0.05). On the GAS, all participants report-ed impro-ved gait at t2 and 80% reported a decrease in spasticity. CONCLUSION: Combining BoNT injection with casting for treatment of elbow flexor spasticity without treat-ing the lower limb may improve hemiparetic gait parameters.

Does casting after botulinum toxin injection improve outcomes in adults with limb spasticity? A systematic review.

OBJECTIVE: To determine current evidence for casting as an adjunct therapy following botulinum toxin injection for adult limb spasticity. DESIGN: The databases MEDLINE, EMBASE, CINAHL and Cochrane Central Register of Controlled Trials were searched for English language studies from 1990 to August 2018. Full-text studies using a casting protocol following botulinum toxin injection for adult participants for limb spasticity were included. Studies were graded according to Sackett's levels of evidence, and outcome measures were categorized using domains of the International Classification of Disability, Functioning and Health. The review was prepared and reported according to PRISMA guidelines. RESULTS: Five studies, involving a total of 98 participants, met the inclusion criteria (2 randomized controlled trials, 1 pre-post study, 1 case series and 1 case report). Casting protocols varied widely between studies; all were on casting of the lower limbs. There is level 1b evidence that casting following botulinum toxin injection improves spasticity outcomes compared with stretching and taping, and that casting after either botulinum toxin or saline injections is better than physical therapy alone. CONCLUSION: The evidence suggests that adjunct casting of the lower limbs may improve outcomes following botulinum toxin injection. Casting protocols vary widely in the literature and priority needs to be given to future studies that determine which protocol yields the best results.

Reliability and Validity of the Modified Heckmatt Scale in Evaluating Muscle Changes With Ultrasound in Spasticity.

OBJECTIVES: To determine the reliability and validity of the Modified Heckmatt scale in assessing muscle echotexture in spasticity. DESIGN: Prospective, observational, 2-center study. Two residents and 2 ultrasound experienced staff physicians each rated 100 ultrasound images that were also analyzed using quantitative gray-scale. SETTING: Academic ambulatory spasticity clinic. PARTICIPANTS: Participants (N=50) included 45 patients with upper or lower extremity spasticity and 5 healthy references. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Modified Heckmatt scale ratings and quantitative gray-scale scores. RESULTS: Inter- and intra-rater intraclass correlation coefficients were 0.76 and 0.81, respectively (P<.001), indicating good to excellent reliability. A significant relationship was found between Modified Heckmatt scores and quantitative gray-scale scores (r=0.829; P<.001). CONCLUSIONS: The Modified Heckmatt scale demonstrated good reliability and validity to assess the pathologic muscle changes that occur in patients with spasticity.

Prompt diagnosis, investigation, and appropriate treatment are important in this subset of patients. This article provides an overview of relevant injury demographics, anatomy, diagnosis, and prognosis, and suggests a treatment algorithm for nerve injury associated with multiligament knee injury.

Trends in reporting of mechanisms and incidence of hip injuries in males playing minor ice hockey in Canada: a cross-sectional study.

BACKGROUND: There has been a noted increase in the diagnosis and reporting of sporting hip injuries and conditions in the medical literature but reporting at the minor hockey level is unknown. The purpose of this study is to investigate the trend of reporting hip injuries in amateur ice hockey players in Canada with a focus on injury type and mechanism. METHODS: A retrospective review of the Hockey Canada insurance database was performed and data on ice hockey hip injuries reported between January 2005 and June 2011 were collected. The study population included all male hockey players from Peewee (aged 11-12 years) to Senior (aged 20+ years) participating in amateur level competition sanctioned by Hockey Canada. Reported cases of ice hockey hip injuries were analyzed according to age, mechanism of injury, and injury subtype. Annual injury reporting rates were determined and using a linear regression analysis trended to determine the change in ice hockey hip injury reporting rate over time. RESULTS: One hundred and six cases of ice hockey-related hip injuries were reported in total. The majority of injuries (75.5%) occurred in players aged 15-20 years playing at the Junior level. Most injuries were caused by a noncontact mechanism (40.6%) and strains were the most common subtype (50.0%). From 2005 to 2010, the number of reported hip injuries increased by 5.31 cases per year and the rate of reported hip injury per 1,000 registered players increased by 0.02 cases annually. CONCLUSION: Reporting of hip injuries in amateur ice hockey players is increasing. A more accurate injury reporting system is critical for future epidemiologic studies to accurately document the rate and mechanism of hip injury in amateur ice hockey players.
