Comprehensive Examination of the Athlete's Shoulder

Shoulder External Over Internal Rotation Ratio Is Related to Biomechanics in Collegiate Baseball Pitching

Altering baseball pitching mechanics affects both performance and the risk of injury. The purpose of this study is to investigate the relationships of shoulder external over internal rotation ratio (SEIR) and other shoulder rotational properties during physical exam and biomechanics of pitching for 177 collegiate baseball pitchers. The shoulder range of motion was quantitatively measured using a custom-made wireless device. Pitching motion data were collected at 240 Hz, and a custom program was created to calculate the throwing arm motion and loading during baseball pitching. Linear regression and analysis of variance tests were performed to investigate the relationships between the shoulder physical exam outcomes and throwing arm biomechanics. SEIR had significant correlations with shoulder horizontal adduction angle at foot contact, maximum shoulder external rotation angle, maximum shoulder linear velocity, and elbow angle at ball release. SEIR groups had significant differences in shoulder proximal force, adduction torque, internal rotation torque, and horizontal adduction torque, and in elbow medial force and varus torque. Glenohumeral internal rotation deficit and total rotational motion deficit had no relationships with throwing arm motions or joint loadings. Shoulder health should be monitored to improve understanding of pitching mechanics in collegiate baseball pitchers.

Clinical and ultrasonographic evaluation of uninjured dominant shoulder in amateur rugby players vs a control group: a pilot study

BACKGROUND

Rugby is a sport involving a great number of shoulder collisions. Traumatic stress of the shoulder can weaken the static stabilizers and promote major injuries as dislocation or full-thickness tears of the rotator cuff. The goal of this study is to evaluate the clinical and ultrasonographic dominant shoulder factures in a group of amateur rugby players, with no history of shoulder injuries, and to compare them with those of a control group.

METHODS

52 male subjects join in the study: 26 amateur rugby players and 26 subjects, which did not practice rugby or competitive sport. Clinical history was obtained from all subjects, followed by dominant shoulder physical and ultrasonographic exams.

RESULTS

Rugby players showed a higher prevalence of positive clinical test, suggesting subacromial impingement than control group (p = 0.01). Among rugby group, five players (19,2%) showed positive test for radiculopathy (p = 0,02), and ten players (73,1%) reported shoulder pain needing pain-reliever drugs at list one time in the last six months (p = 0.001). In rugby group, ultrasound exams showed 23,1% degenerative changes and 30,8% tendon calcifications in supraspinatus tendons (p < 0.05).

CONCLUSIONS

Uninjured dominant shoulder of rugby players shows higher prevalence of clinical and ultrasound changes compare to control. Some rugby players without history of cervical symptoms show positive clinical test of cervical radiculopathy. Clinical and ultrasonographic monitoring of the shoulder can play a role in prevention and knowledge of silent shoulder damage in these athletes.

Clinical and ultrasound findings of 'swimmer's shoulder' and its association with training history in elite Portuguese swimmers: a cross-sectional study

OBJECTIVES

To assess the prevalence of shoulder injuries and ultrasound findings in elite Portuguese swimmers and their association with symptoms and personal or training-related factors.

METHODS

This cross-sectional study was conducted at the Portuguese Open and Youth Swimming National Championships between 27 and 30th July 2022. Each athlete entered details regarding personal and training history into a questionnaire and underwent a physical and ultrasound shoulder examination.

RESULTS

A total of 102 swimmers out of 662 Portuguese athletes were included in the study. Shoulder pain experienced during the previous season was reported by 42% of the athletes. A high prevalence of shoulder structural abnormalities was noted, specifically supraspinatus tendinosis (91%), tears (29%), and subacromial bursitis (29%). Specific training for injury prevention was associated with higher rates of infraspinatus tendinosis (p = 0.047), and supraspinatus tears were linked to greater swimming distances per week (p < 0.001) and practice (p < 0.001), more years of practice (p = 0.018), shoulder pain at the time of evaluation (p = 0.023), a higher number of missed competitions (p = 0.041), and shoulder injections (p = 0.009). Subacromial bursitis was associated with shoulder pain at the time of evaluation (p = 0.002) and during the previous season (p < 0.001), missed competitions (p < 0.001), and requirement for physical therapy (p = 0.006).

CONCLUSIONS

A high prevalence of shoulder morphological changes was found in surveyed swimmers and there were several associations with training load, regardless of individual characteristics of each athlete. It is essential to understand the true impact of current injury prevention programs and to develop effective measures to protect swimmers' health.

When is a Reverse Shoulder Arthroplasty Indicated for a Rotator Cuff Tear?

Rotator cuff tears are the most frequent shoulder injury in patients over 50 years old. Treatment of rotator cuff tears is individualized based on the age, demands, and symptoms of the patient. Nonoperative treatment may often be effective, especially in lower-demand or elderly patients. Surgical repair is indicated after failure of nonoperative treatment or in patients whose high-demand lifestyle requires full strength and function of the shoulder. In older patients, larger tears are less likely to heal and rotator cuff repair may not reliable. In cases of failed previous rotator cuff repair, there may not be enough viable tissue for complete repair. If there is underlying arthritis, a rotator cuff repair is unlikely to resolve all symptoms, and treatment to care for the arthritis and rotator cuff tear is indicated. Reverse shoulder arthroplasty provides the surgical answer for these scenarios and is now being used for numerous indications of shoulder pathology.

Shoulder and Scapular Muscle Activity During Low and High Plank Variations With Different Body-Weight-Bearing Statuses

ABSTRACT

Can, EN, Harput, G, and Turgut, E. Shoulder and scapular muscle activity during low and high plank variations with different body-weight-bearing statuses. J Strength Cond Res 38(2): 245-252, 2024-This study investigated the activation levels and activation ratios of shoulder and scapular muscles during low plank (LP) and high plank (HP) variations, with varying levels of body-mass support, including 4-point, 3-pod, and 2-point body-weight-bearing (BWB) statuses. The study was conducted with 21 healthy men (mean ± SD , 26 ± 6.5 years of age and 24.4 ± 2.4 kg·m -2 BMI). Ten different plank exercises were performed in a mixed order by changing elbow joint positions (LP and HP) and BWB statuses (2-point, 3-pod, and 4-point). Activation levels of the lower trapezius (LT), middle trapezius (MT), upper trapezius (UT), biceps brachii, triceps brachii, infraspinatus, and serratus anterior (SA) muscles were assessed with a surface electromyography device. Results of this study showed that elbow position changes resulted in higher LT ( p = 0.01) and TB ( p = 0.001) activation in HP exercises. In general, it was observed that an increase in BWB status was effective in increasing activation for the scapula and shoulder girdle muscles. The ratios of the UT muscle to the SA, LT, and MT muscles were less than 1 during side plank, bird dog, front reach, shoulder taps, and plank with shoulder external rotation exercises. High plank with toe touch exercise resulted in a marked increase in the UT activation. Therefore, it was concluded plank variations alter activation levels and activation ratios of shoulder and scapular muscles. Plank exercises may be used in shoulder rehabilitation and the progression in plank variations can be achieved by changing elbow position and BWB status based on individual requirements.

Physical therapy management of an athlete with a Kim lesion using physical agents, manual therapy, and therapeutic exercise: a case report

BACKGROUND

Several operative procedures have been described for treating a Kim lesion. However, no physical therapy intervention has been documented as conservative treatment for these cases.

OBJECTIVE

The purpose of this report was to describe a physical therapy management protocol for an athlete with a Kim lesion.

CASE DESCRIPTION

A 22-year-old female volleyball athlete presented to physical therapy with an 8-month history of right shoulder pain when performing the serve and attack sports gestures. Pain was 5/10 on the visual analogue scale (VAS). Pain was localized along the glenohumeral joint, around the long head of the biceps brachii tendon, and at the subscapularis tendon insertion. Shoulder range of motion (ROM) was limited to flexion (150°), abduction (158°), and internal rotation (80°). Kim lesion was confirmed by clinical tests (Kim test and Jerk test) and via magnetic resonance imaging. Shoulder functional outcomes were verified through the University of California Los Angeles (UCLA) shoulder rating scale. Upper extremity sensorimotor control was verified in bimanual support by stabilometry on a baropodometer. Core function was assessed through a plank test and a side plank test. The 8-week course of treatment included manual therapy, physical agents, shoulder and scapular mobilizations, resistance and sensorimotor exercises, core strengthening, and functional exercises.

OUTCOMES

Physical therapy interventions resulted in a decrease in VAS pain (3/10), an increase in shoulder ROM (10.8°) and in UCLA shoulder score (from 22 to 33 points), a reduction in the center of pressure displacement (27-56%), and an increase in plank test (45%) and side plank test (21-29%) performance. The athlete had a full return to sport after the treatment.

CONCLUSION

We concluded that the protocol used for conservative management of Kim lesion resulted in clinical satisfactory physical and functional outcomes for the athlete.

Reliability of the Single-Arm and Double-Arm Jobe Test for the Diagnosis of Full-Thickness Supraspinatus Tendon Tear

Background

The Jobe test is commonly used to diagnose full-thickness (FT) supraspinatus (SSP) tendon tear. The original Jobe test used single-arm testing, although the double-arm Jobe test has also been used in clinical practice.

Purpose

To evaluate the reliability, accuracy, and diagnostic value of the single-arm and double-arm Jobe test for diagnosis of FT SSP tear.

Study Design

Cohort study (diagnosis); Level of evidence, 2.

Methods

Patients with shoulder pain requiring magnetic resonance imaging (MRI) of the shoulder between March 1, 2021, and March 31, 2022, were enrolled. Each patient underwent both single-arm and double-arm Jobe tests by 2 orthopaedic surgeons independently, and the presence of pain, weakness, or both during the test was documented. Diagnosis of FT SSP tear on MRI scan was used as the gold standard to compare the diagnostic value of the Jobe test. The interrater reliability of the Jobe test, and the inter- and intrarater reliability of the MRI evaluation (patients with vs without FT SSP tear) was performed using the kappa (κ) coefficient.

Results

A total of 80 patients (57 females [71%]; mean age, 61.46 ± 9.61 years) were included. MRI scans revealed FT SSP tears in 32 (40%) of the patients. Both single- and double-arm Jobe tests had low diagnostic values (accuracy, 46.25% to 60%; sensitivity, 46.9% to 84.4%; specificity, 25% to 66.7%). The single-arm test with weakness revealed the highest sensitivity (84.4%). The double-arm test with weakness plus pain revealed the highest specificity (66.7%). Double-arm testing with pain had the highest accuracy (60%), with the highest positive likelihood ratio (1.5). The interrater reliability of the Jobe test indicated substantial agreement (double-arm vs single-arm, κ = 0.771 and 0.716, respectively, agreement 85%; P < .05). The interrater reliability of MRI scan evaluation of the FT SSP tear indicated substantial agreement (κ = 0.750, agreement 85%; P < .05), while the intrarater reliability indicated almost perfect agreement (κ = 0.917, agreement 96%; P < .05).

Conclusion

The Jobe test, either single- or double-arm, had low accuracy and diagnostic value in diagnosing FT SSP tear. The concern with a single-arm examination for weakness is that it may be an inappropriate diagnostic test for ruling out FT SSP with 84% sensitivity, while a double-arm examination provides a higher specificity.

Acromioclavicular Joint Injuries in Sport

ABSTRACT

Sport-related shoulder injuries, including disruptions to the acromioclavicular joint (ACJ), are common. An ACJ injury is classified by the degree and direction of the clavicle displacement. Although the diagnosis can be made clinically, standard radiographic views are important to determine the severity of the ACJ disruption and assess for concurrent injuries. The majority of ACJ injuries can be managed nonoperatively; however, surgical treatment is indicated in some cases. Long-term outcomes are generally favorable for most ACJ injuries, and athletes generally return to sport without functional limitations. This article provides an in-depth discussion regarding all aspects of ACJ injuries, including clinically relevant anatomy, biomechanics, evaluation, treatment, and complications.

Glenoid Avulsion of the Glenohumeral Ligament Repair Through a Single Working Portal

Glenoid avulsion of the glenohumeral ligament (GAGL) is a traumatic cause of shoulder instability. GAGL lesions are a rare shoulder pathology most commonly reported as a source of anterior shoulder instability, with no current reports implicating this pathology as a cause of posterior instability. Satisfactory surgical repairs of GAGL lesions with anterior shoulder instability have been well documented; however, this Technical Note highlights the successful repair of a posterior GAGL lesion through a single working portal with suture anchor fixation of the posterior capsule.

Could the Improvement of Supraspinatus Muscle Activity Speed up Shoulder Pain Rehabilitation Outcomes in Wheelchair Basketball Players?

Shoulder pain (SP) is a common clinical complaint among wheelchair basketball (WB) players, since their shoulders are exposed to intense overload and overhead movements. The supraspinatus tendon is the most exposed to WB-related injuries and it is primarily responsible for SP in WB athletes. In these cases, SP rehabilitation remains the main treatment, but there is still a lack of specific protocols which should be customized to WB players' peculiarities and to the supraspinatus muscle activity monitor, and the improvement of rehabilitation outcomes is slow. Thus, the aim of this study was to verify if the improvement of supraspinatus muscle activity, monitored in real time with surface electromyography (sEMG) during the execution of therapeutic exercises, could speed up SP rehabilitation outcomes in WB players. Thirty-three athletes were enrolled. They were divided into two groups. Both groups underwent the same shoulder rehabilitation program, but only the Exercise Plus sEMG Biofeedback Group executed therapeutic exercises while the activity of the supraspinatus muscles was monitored using sEMG. Participants were evaluated at enrollment (T0), at the end of 4 weeks of the rehabilitation program (T1), and 8 weeks after T1 (T2), using the following outcome measures: supraspinatus muscle activity as root mean square (RMS), Wheelchair User's Shoulder Pain Index (WUSPI), shoulder abduction, and external rotation range of motion (ROM). The Exercise Plus sEMG Biofeedback Group improved more and faster for all the outcomes compared to the Exercise Group. The monitoring and improvement of supraspinatus muscle activity seems to be an effective way to speed up SP rehabilitation outcomes in WB players, since it makes the performance of therapeutic exercise more precise and finalized, obtaining better and faster results in terms of recovery of shoulder function.

The Applicability of Provocative Functional Tests in the Diagnosis of Rotator Cuff Muscle Injuries of the Best University Athletes

Rotator cuff disease, external and internal impingement syndromes, low shoulder stability, various types of trauma, and overuse injuries are all related to sports activities. In order to check symptoms in patients with disability and shoulder pain, clinicians use different methods and diagnostic imaging assessment. The research is aimed at evaluating whether there is a difference between provocation function tests (PFT) and ultrasonographic (US) testing of muscles within the rotator cuff in elite collegiate athletes. Patients ( $n=184$ ) were recruited from university team sports selections and tested with a standardized US examination of the shoulder and five PFTs (Speed’s test, Neer’s test, Hawkins test, lift-off test, Yergason’s test). Based on the VAS pain assessment scale, 60 subjects had some pain, which was taken for further processing in the work (124 subjects did not have the presence of pain and were excluded from further processing). The US examination was conducted using Voluson 730 apparatus, by a linear probe, with the frequency in the range of 6-12 MHz. The chi-square test showed significant differences between PFT and the occurrence of shoulder muscle tendinitis for the following variables: Speed’s test and subscapularis tendinitis ( $p=0.02$ ) and Speed’s test and infraspinatus tendinitis ( $p=0.01$ ); Neer test and biceps brachii caput longum tendinitis ( $p=0.01$ ), Neer test and supraspinatus tendinitis ( $p=0.02$ ) and Neer test and infraspinatus tendinitis ( $p=0.01$ ); lift-off test and subscapularis tendinitis ( $p=0.05$ ); and Yergason’s test and biceps brachii caput longum tendinitis ( $p=0.03$ ) and Yergason’s test and subscapitis tendinitis ( $p=0.01$ ). The greatest effect of differences was observed in Neer’s test and biceps brachii caput longum tendinitis ( $\phi =0.60$ ), while the other effects can be described as medium and small in most cases. It can be concluded that functional tests are good predictors of soft tissue changes in the muscles of the rotator cuff of the shoulder. Further monitoring and analysis are needed on a larger number of athletes.

IRO/Shift Test Is Comparable to the Jobe Test for Detection of Supraspinatus Lesions

To determine how the internal rotation and shift (IRO/shift) test compares to the gold standard of clinical tests (Jobe test) for diagnosing supraspinatus lesions and to confirm these clinical results with surgical findings, 100 symptomatic patients were clinically examined between October 2018 and November 2019. All 100 patients were evaluated using both the IRO/shift test and Jobe test. A total of 48 of these patients received surgical intervention. Based on these data, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for both the IRO/shift test and Jobe test were calculated. The IRO/shift test had a sensitivity of 96% (95% CI: 82–100%), specificity of 50% (95% CI: 27–73%), PPV of 73% (95% CI: 56–86%), NPV of 91% (95% CI: 59–100%), and an accuracy of 77% (95% CI: 63–88%). The Jobe test had a sensitivity of 89% (95% CI: 72–98%), specificity of 60% (95% CI: 36–81%), PPV of 76% (95% CI: 58–89%), NPV of 80% (95% CI: 52–96%), and an accuracy of 77% (95% CI: 54–81%). These results suggest that the IRO/shift test is comparable to the Jobe test, which is often viewed as the gold standard clinical examination for assessing supraspinatus lesions. This study was approved by the Ethics Commission of the Martin Luther University Halle-Wittenberg (reference number: 2018-05).

Weakness in patients with subacromial pain syndrome is local and more pronounced in females

BACKGROUND

Subacromial pain syndrome is the predominant cause of shoulder pain, accounting for approximately half of all shoulder complaints. This population presents with weakness of the involved shoulder. However, there is a gap in our understanding of how pain contributes to this weakness, and whether there are sex related differences.

METHODS

Regional and global isometric strength was tested at the involved shoulder joint and remote joints (uninvolved shoulder and both knees) in patients with subacromial pain syndrome. Data were collected before and after acute pain reduction with a subacromial injection.

FINDINGS

Patients demonstrated weakness at the involved shoulder while remote joints demonstrated normal strength. When compared to healthy controls, male patients were shown to exhibit greater levels of weakness than female patients at the involved shoulder, based on comparisons with sex-matched controls using z-scores. Pain reduction (through an anesthetic injection) had no influence on strength in the short-term.

INTERPRETATION

Weakness in patients appears to be sex dependent and is not resolved with reduction of pain. This calls into question the assumptions of the physiological causes of this weakness.

Shoulder Evaluation by Telephone and Video Visit: A Narrative Review

Telemedicine has a very important role in today’s healthcare system, which has been accentuated during the SARS-CoV-2 pandemic. Virtual medical evaluations offer a myriad of benefits for both patients and providers. Evaluations of the musculoskeletal system, however, present unique challenges because diagnosis significantly relies on a physical examination, something not easily accomplished by virtual means. The shoulder, a complex region with four separate articulations, is no exception. Nevertheless, a properly planned and executed telemedicine visit may yield successful results even with challenging shoulder pathologies. This narrative review aims to offer clinicians who are novices in the practice of telemedicine a basic framework with instructions, questions, and some examples of interpretation of patient answers to guide them through encounters for the evaluation of shoulder complaints via telephone and video consultation.

The Shoulder Lever Test - Technical Tip for Instability Assessment in Large Shoulders

INTRODUCTION

The classical shoulder tests for instability of the glenohumeral joint are the load and shift and drawer tests. Here, the humeral head is gripped between fingers and thumb to assess translation. This can be challenging to perform accurately in obese individuals and muscular athletes.

TECHNICAL TIP

The shoulder and upper arm is utilized as a Class 3 lever. By fixing the patient's elbow (fulcrum) and applying translational force on the humerus (force), the instability at the glenohumeral joint (load) can be accurately judged. The mechanical advantage of a Class 3 lever is utilized to generate maximal displacement at the glenohumeral joint by applying minimal translational force at the humerus. The translation can be graded with the modified Hawkins scale.

CONCLUSION

The shoulder lever test obviates the need to grip the humeral head in obese and well-built individuals to accurately judge the translation at the glenohumeral joint, improving the clinical yield.

Ultrasound-Guided Biceps Tendon Sheath Injections Frequently Extravasate Into the Glenohumeral Joint

PURPOSE

To evaluate the frequency of glenohumeral joint extravasation of ultrasound (US)-guided biceps tendon sheath injections.

METHODS

Fifty shoulders with a clinical diagnosis of bicipital tenosynovitis pain received a US-guided biceps sheath injection with anesthetic, steroid, and contrast (5.0 mL mixture) followed immediately by orthogonal radiographs to localize the anatomic distribution of the injection. Radiographic evaluation of contrast localization was determined and interobserver reliability calculated.

RESULTS

All 50 postinjection radiographs (100%) demonstrated contrast within the biceps tendon sheath. In addition, 30 of 50 (60%) radiographs also revealed contrast in the glenohumeral joint. Interobserver reliability for determination of intraarticular contrast was good (kappa value 0.87).

CONCLUSIONS

US-guided bicipital sheath injections reproducibly result in intrasheath placement of injection fluid. Bicipital sheath injections performed with 5 mL of volume result in partial extravasation into the joint 60% of the time. These data may be useful for surgeons who use the results of diagnostic biceps injections for diagnosis and surgical decision-making.

LEVEL OF EVIDENCE

III, prospective cohort study, diagnosis.

Measurement of biceps tendon retraction after arthroscopic tenotomy

BACKGROUND

One of the treatment options for long head of the biceps tendon (LHBT) pathology is tenotomy. To our knowledge, no study in the literature has evaluated the degree of retraction after tenotomy. The goals of this study were to determine the distance of this retraction and to identify its relationship with patient characteristics.

METHODS

We conducted an observational prospective survey over a 3-month period among 30 patients operated on arthroscopically by the same surgeon between August 2018 and April 2019. A radiopaque device was introduced inside the LHBT before tenotomy. Radiographs were obtained to evaluate the distance of retraction on day 1, day 30, and day 90.

RESULTS

Thirty patients were included, of whom 63.3% (19) were women. Surgery was performed for a rotator cuff tear in 10 patients (33.3%) and for subacromial impingement in the remainder of patients (66.7%) after failure of conservative management. The mean retraction of the LHBT (distance between the glenoid and clip) increased from 1.9 cm (day 1) to 3.5 cm (day 90). Three radiographic measurements were performed, and all 3 showed significant increases from day 1 to day 90. According to the Student t test, the mean retraction in the subacromial impingement group was significantly higher than that in the rotator cuff tear group on day 1, day 30, and day 90. Body mass index, younger age, sex, and dominant hand did not show any relation with LHBT retraction (P > .05). The mean LHBT retraction was significantly higher on day 90 in patients presenting with a positive Popeye sign (P < .05).

CONCLUSION

At 3 months of follow-up, the mean LHBT retraction was 3.5 cm from the glenoid and 2.5 cm from the greater tuberosity. It dynamically increased from day 1 to day 90. The LHBT will retract and sit beyond the transverse humeral ligament in the bicipital groove. The LHBT retracts significantly more when early mobilization of the shoulder is allowed.

Increased hip arthroscopy operative duration is an independent risk factor for overnight hospital admission

PURPOSE

The purpose of this study was to determine the association between operative duration and short-term complications as well as overnight hospital admission following hip arthroscopy.

METHODS

Hip arthroscopy cases from 2006 to 2016 were retrieved from the National Surgical Quality Improvement Program registry, which prospectively collects 30-day postoperative complications. Patients were stratified into the following groups based on procedure length: group 1 (< 60 min), group 2 (60-120 min), and group 3 (> 120 min). Preoperative characteristics were compared across the cohorts. Multivariate regressions were used to compare complication rates and overnight hospital admission between the three groups. Independent risk factors for overnight hospital admission were characterized.

RESULTS

A total of 2129 hip arthroscopy cases were identified. Average operative duration was 99.3 ± 55.7 min. As operative time increased, patients were more likely to be younger, male, and had lower American Society of Anesthesiologists (ASA) class (p < 0.001). Body mass index and comorbidity profiles were similar across the patient cohorts, with the exception of hypertension being more prevalent in the shorter operative time cohort (p < 0.001). Patients in group 3 were more likely to stay overnight in the hospital (26.0%) compared to patients in groups 1 (7.7%) and 2 (10.9%), p < 0.001). All postoperative complication rates were otherwise similar between the cohorts. Independent risk factors for overnight hospital admission included increasing operative time (most notably > 120 min relative to < 60 min, relative risk [RR] = 3.53, 95% CI 2.50-5.00, p < 0.001) and increasing ASA classification (most notably ASA III or IV relative to ASA I, RR = 1.64, 95% CI 1.18-2.27; p = 0.013).

CONCLUSIONS

Increasing operative duration was not associated with increased postoperative complications following hip arthroscopy. However, patients were more than three times likely to stay in the hospital overnight if their surgery was longer than 120 min, relative to cases that were less than 60 min.

Management Options for Shoulder Impingement Syndrome in Athletes: Insights and Future Directions

Athletes participating in overhead sports are at particularly high risk of shoulder impingement syndrome. Subcoracoid impingement is defined as impingement of the anterior soft tissues of the shoulder between the coracoid process and the lesser tuberosity. Subacromial impingement syndrome (SIS) occurs due to extrinsic compression of the rotator cuff between the humeral head and coracoacromial structures or intrinsic degeneration of the supraspinatus tendon and subsequent superior migration of the humerus. Internal impingement is a major cause of shoulder pain in overhead athletes, and it occurs due to repetitive impingement of the articular surface of the rotator cuff with the glenoid during maximum abduction and external rotation of the arm. When examining athletes with suspected impingement of the shoulder, it is important to discuss the sport-specific motion that regenerates the symptoms and perform a combination of physical examination tests to improve the diagnostic accuracy. Radiographic evaluation is recommended, and the extent of soft tissue abnormalities can be assessed on ultrasound or magnetic resonance imaging of the shoulder. Management of shoulder impingement syndrome can be conservative or operative, based on the severity and chronicity of symptoms and the associated structural abnormalities. This review provides an update on the management of SIS, subcoracoid impingement, and internal impingement in the athletic population.

Telemedicine for Musculoskeletal Rehabilitation and Orthopedic Postoperative Rehabilitation

Telehealth visits result in high-quality care, with high patient and provider satisfaction. Strong evidence suggests that virtual physical therapy is noninferior to conventional face-to-face physical therapy for a variety of musculoskeletal disorders. Postoperative telerehabilitation has a strong positive effect on clinical outcomes, and the increased intensity telerehabilitation programs offer is a promising option for patients. Studies demonstrate effective virtual postoperative management. The novel coronavirus disease 2019 pandemic has led to improved reimbursement for telehealth visits and accelerated widespread implementation of telemedicine. This article establishes experience and evidence-based practice guidelines for conducting telemedicine visits, with emphasis on the virtual physical examination.
