Central Retinal Artery Occlusion Following Intralesional Triamcinolone Injection for IgG4-related Orbital Disease.

The risk of blindness associated with periocular and facial injections is well documented. Previous cases describing vision loss following a recent periocular or facial injection have emphasized the importance of facial "danger zones." To date, the literature suggests that nearly half of all cases of central retinal artery occlusion in the setting of a recent periocular or facial injection involve an injection in or around the nose.

Partial thickness subfoveal hole in a patient treated with tamoxifen: a case report and review of the literature.

Background: We describe a patient presenting with a partial thickness subfoveal hole in the right eye after tamoxifen treatment for breast cancer.

Case Presentation: A 76-year-old Caucasian female presented with a 1-day history of acute central scotoma and blurry vision in the right eye. The patient had been receiving oral tamoxifen for 5 years as adjuvant treatment for stage I lobular breast cancer.

Ganglion Cell Layer Thickness Change in Neovascular Age-Related Macular Degeneration Treated With Anti-VEGF Injections.

Purpose: This work assesses bilateral ganglion cell layer-inner plexiform layer (GCL-IPL) thickness changes in patients with unilateral neovascular age-related macular degeneration (nAMD) treated with antivascular endothelial growth factor (anti-VEGF).

Methods: In this single-center, retrospective, cohort study, the medical records of patients with unilateral nAMD treated with anti-VEGF were reviewed. The treated group included eyes with newly diagnosed nAMD that subsequently underwent treatment with intravitreal anti-VEGF injections.

Characterization of Posterior Glenoid Bone Loss Morphology in Patients With Posterior Shoulder Instability.

Purpose: To systemically describe posterior bone defects in the setting of posterior shoulder instability based on several parameters, including surface area, slope and version, defect height from the base of the glenoid, and extent of bone loss at equal intervals along the long axis of the fossa.

Methods: A total of 40 young, active individuals with recurrent posterior shoulder instability and a bony injury confirmed on either computed tomography (n = 18; mean age, 26.3 ± 4.

Jones Fractures Identified at the National Football League Scouting Combine: Assessment of Prognostic Factors, Computed Tomography Findings, and Initial Career Performance.

Background: Jones fractures result in subsequent dysfunction and remain an issue for athletes.

Purpose: To (1) describe the epidemiology, treatment, and impact of Jones fractures identified at the National Football League (NFL) Scouting Combine on players' early careers and (2) establish the value of computed tomography (CT) to determine bony healing after a fracture in prospective players.

Study Design: Cohort study; Level of evidence, 3.

Prevalence of Shoulder Labral Injury in Collegiate Football Players at the National Football League Scouting Combine.

Background: Labral tears confirmed by magnetic resonance imaging (MRI) are a relatively common injury among collegiate athletes and can influence a player's ability to compete at the professional level.

Purpose: To determine the prevalence of MRI-confirmed shoulder labral injuries in collegiate football players entering the National Football League (NFL) Combine and to further describe these injuries by tear location, player position, history of surgical intervention, and associated concomitant shoulder injuries.

Study Design: Descriptive epidemiology study.

The Epidemiology of Ankle Injuries Identified at the National Football League Combine, 2009-2015.

Background: American football is a leading cause of sports-related injuries, with the knee, ankle, and shoulder most commonly involved.

Purpose/hypothesis: The purpose of this study was to describe the epidemiology, characteristics, and imaging findings of ankle injuries in football players at the National Football League (NFL) Combine and determine the relationship to player position. We hypothesized that there would be a high relative incidence of ankle injuries in these players compared with other sports and that there would be a direct correlation between the incidence of ankle injuries and player position.

A History of Anterior Cruciate Ligament Reconstruction at the National Football League Combine Results in Inferior Early National Football League Career Participation.

Purpose: To evaluate whether players with a history of an anterior cruciate ligament reconstruction (ACLR) before the National Football League (NFL) Combine played or started fewer games and/or participated in fewer eligible snaps compared with NFL Combine participants without a history of knee injury or surgery.

Methods: We performed a retrospective review of all players who participated in the NFL Combine between 2009 and 2015 and who had a history of an ACLR. NFL Combine participants were included if they had a previous ACLR or combined anterior cruciate ligament (ACL) injury and nonoperatively managed medial collateral ligament injury.

Multicompartmental Osteochondral Allografts of Knee and Concomitant High Tibial Osteotomy.

Chondral lesions of the knee can occur secondary to limb malalignment. To address these interrelated problems, a high tibial osteotomy with concomitant osteochondral allograft transfer may be performed. It is important to address these chondral lesions as they often affect the young and active population and cause morbidity in an otherwise healthy population.

Arthroscopic Labral Repair in the Setting of Recurrent Posterior Shoulder Instability.

Posterior shoulder instability, although relatively rare in the general population, is more commonly seen in athletes, especially those in contact sports. Although nonoperative treatment has been associated with satisfactory results in the setting of posterior shoulder instability, conservative management may ultimately fail and lead to recurrence particularly in young, male patients. Both arthroscopic and open repair techniques to address posterior instability have been described, with each showing positive patient-reported outcomes, low risk of recurrence, and considerably high return-to-sport rates.

Superior Capsular Reconstruction With Superimposition of Rotator Cuff Repair for Massive Rotator Cuff Tear.

Massive rotator cuff tears are particularly challenging to treat and severely limit the function of the shoulder. Compared with a small rotator cuff tear, massive tears are more unpredictable and usually present with low tendon quality. When performing an anatomical repair of the rotator cuff, the surgical treatment is often associated with failure of the construct.

Arthroscopic Rotator Cuff Repair With Mini-open Subpectoral Biceps Tenodesis.

With a range of tear characteristics such as chronicity, degree of fatty atrophy, and number of tendons involved as well as varying patient-specific characteristics including age, injury mechanism, and expectations after treatment to consider, proper and successful treatment of a rotator cuff tear is multifactorial and, consequently, challenging. Although conservative management of a rotator cuff tear may be successful, a more severe tear with involvement of more tendons may warrant surgical intervention. Furthermore, additional pathology including biceps tendinopathy may result in greater patient morbidity and an even more complex treatment decision-making process and surgical technique.

Repair of an Isolated Coracoid Fracture With Suture Anchor Fixation.

Coracoid fractures are rare injuries, which may occur in isolation or in association with other shoulder pathology. The mechanism of trauma consists of a strong contraction of the conjoint tendon as a result of direct trauma. The diagnosis is usually difficult and many times overlooked, thereby requiring a high level of suspicion.

Reverse Total Shoulder Arthroplasty With Humeral Head Autograft Fixed Onto Glenoid for Treatment of Severe Glenoid Retroversion.

Advanced glenohumeral osteoarthritis can transform glenoid morphology and, in some cases, is found in association with severe glenoid retroversion. The associated glenoid retroversion leads to difficulty in fixation of the glenoid component in reverse total shoulder arthroplasty. In the context of extreme glenoid wear, structural grafts can be used to restore glenoid volume and version in order for the glenoid component of the reverse total shoulder arthroplasty to be more easily implanted.

Quantitative Assessment of the Coracoacromial and the Coracoclavicular Ligaments With 3-Dimensional Mapping of the Coracoid Process Anatomy: A Cadaveric Study of Surgically Relevant Structures.

Purpose: To perform a quantitative anatomic evaluation of the (1) coracoid process, specifically the attachment sites of the conjoint tendon, the pectoralis minor, the coracoacromial ligament (CAL), and the coracoclavicular (CC) ligaments in relation to pertinent osseous and soft tissue landmarks; (2) CC ligaments' attachments on the clavicle; and (3) CAL attachment on the acromion in relation to surgically relevant anatomic landmarks to assist in planning of the Latarjet procedure, acromioclavicular (AC) joint reconstructions, and CAL resection distances avoiding iatrogenic injury to surrounding structures.

Methods: Ten nonpaired fresh-frozen human cadaveric shoulders (mean age 52 years, range 33-64 years) were included in this study. A 3-dimensional coordinate measuring device was used to quantify the location of pertinent bony landmarks and soft tissue attachment areas.

Posterior Capsulotomy of the Knee: Treatment of Minimal Knee Extension Deficit.

The loss of knee extension, even if minimal, is disabling and considerably affects the individual's quality of life. This loss of extension can be a consequence of prior surgery, including a previous anterior cruciate ligament reconstruction. Although this loss of extension may be treated through an isolated arthroscopic procedure, a more severe case may warrant an invasive approach.

Intra-articular Anterior Cruciate Ligament Reconstruction With Extra-articular Lateral Tenodesis of the Iliotibial Band.

An increasing concern has been given to the rotation stability of the knee in the setting of an anterior cruciate ligament (ACL) reconstruction. This growing interest stems from a better understanding of the rotational stability of the knee afforded by the identification of the anterolateral ligament. Previously, a residual abnormal pivot-shift test had been found after an anatomic single-band reconstruction of the ACL because of a lack of rotational stability, which may lead to the development of osteoarthritis.

Subpectoral Biceps Tenodesis: Interference Screw and Cortical Button Fixation.

Bicep tendon pathology often arises from chronic overuse injuries, acute trauma, or degenerative changes in the glenohumeral joint. These injuries can cause significant shoulder pain, and can greatly limit range of motion and, in turn, activities of daily living. The diagnosis of biceps pathologies can be challenging, because patients often present with nonspecific symptoms.

Arthroscopic Superior Capsule Reconstruction Technique in the Setting of a Massive, Irreparable Rotator Cuff Tear.

Massive, irreparable rotator cuff tears are challenging to treat and associated with pain and severe limitation in shoulder elevation due to the proximal migration of the humeral head and, consequently, subacromial impingement. Furthermore, retraction of the tendons in combination with fat infiltration and muscular weakness results in unpredictable treatment outcomes. While conservative treatment may be warranted for low-demand patients, surgical treatment is often indicated for a successful return to activities of daily living as well as an improved quality of life.

Open Repair of an Anterior Humeral Avulsion of the Glenohumeral Ligament.

A humeral avulsion of the glenohumeral ligament, or HAGL lesion, is an uncommon yet disabling shoulder injury, which leads to complaints of pain and overall inability to properly use the shoulder from patients. The diagnosis of a HAGL lesion is particularly challenging. To arrive at an accurate diagnosis, the use of a magnetic resonance arthrogram is suggested along with high clinical suspicion.

Sternoclavicular Joint Reconstruction in the Setting of Medial Comminuted Clavicle Fracture.

A dislocation of the sternoclavicular joint is a particularly threatening injury given the close proximity of neighboring vital structures. Moreover, a traumatic injury resulting in a comminuted fracture of the medial clavicle in addition to joint instability results in even greater complexity. In the setting of sternoclavicular joint instability, definitive treatment that will lead to complete resolution of symptoms is necessary.

Pectoralis Major Transfer for Treatment of Serratus Anterior Dysfunction in the Setting of Long Thoracic Nerve Palsy.

Symptomatic scapular winging resulting in scapular dyskinesia leads to a wide spectrum of clinical complaints, most notably periscapular pain. The malpositioning of the scapula, termed through use of the acronym SICK (scapular malposition, inferior-medial border prominence, coracoid pain and malposition, and dyskinesia of scapular movement), is due to the irregular activity of one or more of the periscapular muscles. In particular, the serratus anterior, innervated by the long thoracic nerve, is a key muscle that stabilizes the scapula and provides coordinated scapulohumeral rhythm.

Osteotomy of the Tibial Tubercle for Anteromedialization.

Patellofemoral instability is a common cause of anterior knee pain, especially in younger and more active patients. Treatment of instability varies considerably depending on the patient's symptoms as well as the cause of the instability. Lateral instability has a particularly broad spectrum of treatment algorithms including patellar taping, arthroscopy, lateral release, medial patellofemoral ligament (MPFL) reconstruction, MPFL repair, and osteotomy of the tibial tubercle for realignment.
