One hundred twelve practicing members of the American Shoulder and Elbow Surgeons in the United States and Canada were surveyed regarding use of weighted views of the acromioclavicular joint. They were also asked about treatment for hypothetical patients seen in the emergency department or office with grade II or III acromioclavicular separations. One hundred five physicians (94%) responded to the survey. Eighty-five members (81 %) did not recommend obtaining weighted views in the emergency department. Sixty members (57%) did not use weighted views, and the majority commented that weighted views had no influence on their decision-making regarding treatment. Forty-five members (43%) used weighted views, but most did not use the results of this test to determine surgical intervention. Physicians recommending weighted views averaged 21 years of practice, compared with 16 years for those who did not obtain weighted views. Only nine physicians (9%) had changed treatment on the basis of weighted views. The patient's arm dominance, work, or athletic status did not influence most surgeons' decision to perform surgery when weighted views revealed a grade III separation. We found no correlation between obtaining weighted views and performing surgical reconstruction for patients with grade III acromioclavicular separations. [ABSTRACT FROM AUTHOR]

Athletes in sports such as baseball, gymnastics, weight lifting, javelin, and racket sports are susceptible to stress lesions in the bones of the upper extremities. Injuries range from periostitis to bone spurs to stress fractures. Injuries in adolescents typically involve the growth plates, while mid-shaft injuries at the area of muscle insertion are more common in adults. It's especially important to detect these injuries in adolescents because untreated stress lesions at growth plates can have serious consequences. Plain films demonstrate obvious fractures and physeal injuries, but triple-phase bone scans are often needed to define the extent of stress lesions. [ABSTRACT FROM AUTHOR]

Background: There is a lack of published information outlining the use of biologics in National Football League (NFL) athletes and limited data to guide biologic treatment strategies., Purpose: To develop a consensus on the use of biologics among NFL team physicians., Study Design: Consensus statement., Methods: A working group of 6 experts convened a consensus process involving NFL team physicians using validated Delphi methodology. Physicians from 32 NFL teams as well as NFL London were invited to take part. This iterative process was used to define statements on the use of biologics in NFL athletes. A recent scoping review exploring biologics in professional athletes was used to inform the first of 3 rounds of surveys, with statements considered under 7 headings: biologics in general, challenges of treating NFL athletes, terminology/nomenclature, autologous blood products, cell-based therapies, guidance for NFL team physicians, and biologic research in the NFL. In addition to rating agreement, experts were encouraged to propose further items or modifications. Predefined criteria were used to refine item lists after each survey. For a consensus within the final round, defined a priori, items were included in the final information set if a minimum of 75% of respondents agreed and fewer than 10% disagreed., Results: Physicians from 26 NFL teams and NFL London responded to the initial invitation to participate in the Delphi process; 88.9% of participating team physicians completed the round 1 survey, with response rates of 87.5% in round 2 and 95.2% in round 3. After 3 rounds, 47 statements reached a consensus. A consensus was achieved that platelet-rich plasma has a positive impact on patellar tendinopathy and on symptoms in early osteoarthritis but not for other indications. NFL team physicians agreed that while cell therapies have the potential to improve symptoms, the misrepresentation of uncharacterized preparations as "stem cells" has contributed to the widespread use of unproven therapies., Conclusion: This study established an expert consensus on 47 statements relating to the use of biologics in NFL athletes. In addition to providing clinical guidance for the use of biologics in NFL athletes, this study identified key areas for future focus including the development of athlete education materials., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: I.R.M. has received consulting fees from Arthrex and Stryker.

Introduction: Coronavirus disease 2019 (COVID-19) infections have strained hospital resources worldwide. As a result, many facilities have suspended elective operations and ambulatory procedures. As the incidence of new cases of COVID-19 decreases, hospitals will need policies and algorithms to facilitate safe and orderly return of normal activities. We describe the recommendations of a task force established in a multi-institutional healthcare system for resumption of elective operative and ambulatory procedures applicable to all hospitals and service lines., Methods: MedStar Health created a multidisciplinary task force to develop guidelines for resumption of elective surgeries/procedures. The primary focus areas included the establishment of a governance structure at each healthcare facility, prioritization of elective cases, preoperative severe acute respiratory syndrome coronavirus 2 testing, and an assessment of the needs and availability of staff, personal protective equipment, and other essential resources., Results: Each hospital president was tasked with establishing a local perioperative leadership team answering directly to them and granted the authority to prioritize elective surgery and ambulatory procedures. An elective surgery algorithm was established using a simplified Medically Necessary Time Sensitive score, with multiple steps requiring a "go/no-go" assessment based on local resources. In addition, mandatory preoperative COVID testing policies were developed and operationalized., Conclusions: Even when the COVID pandemic has passed, hospitals and surgical centers will require COVID screening and testing, case prioritization, and supply chain management to provide care essential to the surgical patient while protecting their safety and that of staff. Our guidelines consider these factors and are applicable to both tertiary academic medical centers and smaller community facilities., Competing Interests: Disclosure: The authors declare that they have nothing to disclose., (Copyright © 2020 The Author(s).

Background: Standard nonoperative therapy for acute muscle strains usually involves short-term rest, ice, and nonsteroidal anti-inflammatory medications, but there is no clear consensus on how to accelerate recovery., Hypothesis: Local delivery of platelet-rich plasma to injured muscles hastens recovery of function., Study Design: Controlled laboratory study., Methods: In vivo, the tibialis anterior muscles of anesthetized Sprague-Dawley rats were injured by a single (large strain) lengthening contraction or multiple (small strain) lengthening contractions, both of which resulted in a significant injury. The tibialis anterior either was injected with platelet-rich plasma, was injected with platelet-poor plasma as a sham treatment, or received no treatment., Results: Both injury protocols yielded a similar loss of force. The platelet-rich plasma only had a beneficial effect at 1 time point after the single contraction injury protocol. However, platelet-rich plasma had a beneficial effect at 2 time points after the multiple contraction injury protocol and resulted in a faster recovery time to full contractile function. The sham injections had no effect compared with no treatment., Conclusion: Local delivery of platelet-rich plasma can shorten recovery time after a muscle strain injury in a small-animal model. Recovery of muscle from the high-repetition protocol has already been shown to require myogenesis, whereas recovery from a single strain does not. This difference in mechanism of recovery may explain why platelet-rich plasma was more effective in the high-repetition protocol, because platelet-rich plasma is rich in growth factors that can stimulate myogenesis., Clinical Relevance: Because autologous blood products are safe, platelet-rich plasma may be a useful product in clinical treatment of muscle injuries.

We present 4 patients who underwent mobilization and repair of large or massive rotator cuff tears (maximum dimension, >/=3.0 cm). In all 4 patients, sterile synovio-cutaneous fistulas developed within several weeks of the index procedure. All required further debridement surgery, multiply in 3 cases, with 1 case requiring a rotational flap for wound closure. Tissue at surgery appeared necrotic and avascular, with extensive inflammatory response, and we postulate that this was possibly related to the extensive mobilization needed to achieve cuff closure. Despite the complications, all fistulas eventually were closed, and all 4 patients were eventually satisfied with the functional status of their shoulders. We conclude that a sterile synovio-cutaneous fistula is a possible complication of mobilization and repair of large or massive rotator cuff tears.

Muscle strains, frequently the result of a lengthening contraction, sometimes are treated with corticosteroids. We tested whether an injection of dexamethasone administered soon after muscle injury would minimize inflammation and facilitate the recovery of contractile tension. We applied one eccentric contraction on the tibialis anterior of 76 rats, which were randomly assigned to one of three groups: sham-injured plus dexamethasone, injured plus vehicle, and injured plus dexamethasone. Electrophysiology, histology, and reverse transcription-polymerase chain reaction were used to study the relation between contractile tension, inflammation, and the expression of inflammatory molecules. The single eccentric contraction led to a reversible muscle injury characterized initially by reduced contractile tension and inflammation. The dexamethasone injection reduced the expression of interleukin-1beta and transforming growth factor-beta1 compared with injured vehicle-injected controls and led to a transient improvement of contractile tension 3 days after the injury. No adverse effects were seen for as much as 3 weeks after the dexamethasone injection. The data indicate that one dose of dexamethasone administered soon after muscle strain may facilitate recovery of contractile tension without causing major adverse consequences in this experimental model.

Although less common than injuries to the knee or shoulder, elbow injuries can be a substantial challenge to sports medicine providers. Many elbow problems respond to routine nonoperative measures including periods of activity modification and physical therapy, but others may ultimately require surgery. Following surgery, appropriate attention to rehabilitation is important to achieve optimal function. This article addresses some of the more common sports-related operative elbow pathology, basic principals of surgery (with an emphasis on techniques only where it may impact rehabilitation or return-to-sport decisions), and return-to-play decisions (including typical "targeted" time frames). The emphasis is on an understanding of sport-specific functional demands and the difficult assessment of reinjury risk following surgery.

Background: Injury to the anterior cruciate ligament (ACL) often requires surgery and extensive rehabilitation. Women who participate in collegiate sports and military drills are more likely to injure their ACL than are men participating in similar activities. The influence of the normal fluctuation of sex hormones on the physical properties of the ACL is one potential cause for this disparity. The purpose of this study was to report the correlation between estradiol, estrone, estriol, progesterone, and sex hormone binding globulin (SHBG) and ACL stiffness during three phases of the menstrual cycle in normally cycling, healthy females., Methods: We tested ACL stiffness and collected blood from 20 female subjects who were not using oral contraception during three phases of their menstrual cycle. Ligament stiffness was tested with the KT-2000 trade mark knee arthrometer (MEDmetric, San Diego, CA). Concentrations of estradiol and SHBG were assessed via radioimmunoassay (RIA). Progesterone, estriol, and estrone concentrations were determined via enzyme-linked immunoassay., Results: Spearman rank correlation analysis indicated a significant correlation between estradiol concentration and ACL stiffness (-0.70, p < 0.001) and estrone concentration and ACL stiffness near ovulation (0.46, p = 0.040). With the effects of the other variables controlled, there was a significant partial correlation between estradiol (-0.80, p < 0.001), estriol (0.70, p = 0.003), and progesterone (0.66, p = 0.005) and ACL stiffness near ovulation., Conclusions: Our results indicate that there is a significant correlation between estradiol, estriol, and progesterone and ACL stiffness suggesting that fluctuating levels of sex hormones may influence the stiffness of the ACL near ovulation. Future studies that examine the relationship between sex hormones and the physical properties of the ACL should be focused near the ovulation phase of the menstrual cycle.

A case of myotonia congenita in an adolescent athlete was presented. Although this is a rare condition unknown to many treating physicians, the key to diagnosis was provocation of the patient's symptoms of muscle "tightening" and "cramping" during sustained exercise. The diagnosis would have been missed in routine office examinations with the patient at rest. The stereotypic generalized myotonic signs and symptoms were provoked after the patient was asked to play 20 minutes of basketball during one of his office evaluations. The provocative or postexercise examination was critical to the diagnosis as the resting office examination was completely normal. The diagnosis was subsequently confirmed by EMG and genetic testing. Myotonia congenita should be considered in the differential diagnosis of athletes with exercise-induced muscle "stiffness" or "cramping," particularly if the course is protracted and initial examinations are unremarkable. A provocative exercise period can be used to make the diagnosis. Once the diagnosis is established, appropriate pharmacologic treatment may improve symptoms and allow return to daily activity without restriction.

Currently a myriad of devices are available for immobilization of the injured or postsurgical upper extremity. Some of these devices are straightforward and easily used, but some are more complicated and require more familiarity for their successful application. However, even simple devices have the potential for misapplication and thus prevent their benefit to the patient. This article is the third in a 3-part series. The goals of the series are (1) to present and review several devices on the market used by shoulder surgeons to immobilize the upper extremity, and (2) to discuss proper application and precautions of their use. It is intended that this series will benefit nurses, therapists, and trainers involved in the use of these devices.

Forty-two team orthopedists representing all 28 major league baseball teams were surveyed to ascertain their definitive treatment for a hypothetical starting rotation pitcher who had sustained a grade III acromioclavicular (AC) separation to his throwing arm 1 week before the season. Twenty-nine (69%) of the physicians would treat the injury nonoperatively, while 13 (31%) would operate immediately. Twenty-five (60%) of the orthopedists had actually treated a pitcher or position baseball player with a grade III AC separation in the throwing arm, the 25 treating a total of 32 patients. Twenty (63%) of these injuries were treated nonoperatively, and 12 (37%) were treated operatively. The physicians reported that 16 (80%) of the patients treated nonoperatively regained normal function and achieved complete relief of pain, while 18 (90%) had normal range of motion after treatment; of those treated operatively, 11 (92%) regained normal function, achieved complete relief of pain, and had normal range of motion after surgery.

An understanding of the anatomy and biomechanical features of the glenohumeral joint is necessary when understanding the concept of shoulder laxity. Glenohumeral laxity is a normal feature of shoulder motion, but only when that laxity becomes excessive does instability occur. The clinician must use the history and physical examination to distinguish normal from pathological laxity. Several examination techniques are commonly used to evaluate anterior, posterior, inferior, and multidirectional shoulder laxity. It has become appreciated the subluxation of the shoulder is clinically or symptomatically unstable. This paper reviews the current techniques to evaluate shoulder laxity and discusses the interpretation of these examinations as they relate to normal and pathological laxities.

The glenohumeral joint relies on static and dynamic contributions of the local soft tissues to maintain joint stability. Dynamic stabilizers consist of the local musculature (the rotator cuff and periscapular muscles), whereas static stabilizers include the glenoid labrum and associated capsuloligamentous components. The functional interaction of static and dynamic components is complex and not completely understood. Selective cutting studies have been done to define the effect of sectioning various static components on resultant glenohumeral translation. These studies have played a pivotal role in the understanding of static factors controlling shoulder stability: the anatomic variability in capsuloligamentous anatomy has been recognized, and the complex interaction among various regions of the shoulder capsule and their labral attachment sites has been shown. Additionally, it has been recognized that the function of the capsuloligamentous restraints is highly dependent on arm position.

Fifty-five patients considering a hindfoot fusion performed by the senior author over a 5-year period were given the choice of having the fusion augmented by either iliac crest bone graft or demineralized bone graft in a study of the relative efficacy of these 2 methods of bone grafting. Eleven patients underwent subtalar fusion (average age, 40.1 +/- 14.0 years), and 44 had a triple arthrodesis (average age, 54.6 +/- 19.2 years). The most common indications for surgery were posterior tibial tendon insufficiency and traumatic arthritis. There were no significant differences between groups regarding underlying disease, medications, or associated medical conditions. In isolated subtalar fusions, all 3 patients who received an iliac crest bone graft experienced healing, as did 7 of 8 patients who received demineralized bone graft. The eighth patient had a radiographic non-union without clinical symptoms. Complete healing of triple arthrodeses was achieved in 13 of 15 patients who received an iliac crest bone graft and in 29 of 29 patients receiving a demineralized bone graft. There were no intergroup differences in the time to union, which generally was between 3 and 4 months. Intraoperative blood loss was significantly less with demineralized bone graft (33 +/- 25 ml) than with iliac crest bone graft (206 +/- 192 ml). This study demonstrated that demineralized bone graft aids arthrodesis at least as well as does iliac crest bone graft, without the increased blood loss, cost, and postoperative pain associated with iliac crest bone harvest.
