Arthroscopic Outside-In Shoulder Release for Patients With an Inaccessible Glenohumeral Joint.

ABSTRACT: Rotator interval release is an important procedure used in many shoulder operations. It is currently performed through an intra-articular approach, which may result in incomplete release or tissue removal. Here, we introduce an outside-in rotator interval release technique for complete rotator interval tissue removal, which is performed mainly through the lateral portal and a distal anterior portal under the coracoacromial arch. This technique can be used for many shoulder conditions, such as severe joint contracture or fibrosis, fixed shoulder dislocation, or disorders of the long head of the biceps. Our experience indicates that this technique is easy, effective, and capable of addressing even the most difficult shoulder conditions. We believe that adoption of this technique by surgeons can facilitate the success of many shoulder operations.

Arthroscopic Outside-in Shoulder Release for Patients With an Inaccessible Glenohumeral Joint.

Project description:Severe shoulder contracture, which usually results from severe frozen shoulder or traumatic arthrofibrosis, is clinically quite common. This condition requires surgical release resulting from severe functional impediment. However, most surgeons are reluctant to operate on such patients because the glenohumeral joint is always inaccessible because of contracture severity. Thus, we introduced an outside-in shoulder release technique starting from the posterior side of the glenohumeral joint. This procedure includes the fabrication of posterior and inferior posterior portals, locating the glenohumeral space out of the capsule, creating working space just posterior to the posterior capsule, releasing the posterior capsule, and thereafter releasing the inferior and superior capsules. Our clinical experience indicates that this procedure can be performed safely and effectively when certain guidelines are followed and can allow for subsequent access to the glenohumeral joint in most cases. We think the introduction of this technique will provide a special surgical option for patients with severe joint contracture.

Arthroscopic Release of Severe Flexion- and Extension-Impeding Knee Stiffness With Inaccessible Joint.

Project description:Knee stiffness with severe flexion and extension impediment is a common clinical condition that challenges orthopaedic surgeons. Arthroscopic release techniques have been reported, mostly for slight extension or flexion deficits. However, for severe flexion- and extension-impeding knee stiffness, especially when there is no intra-articular space in which to place the arthroscope, effective arthroscopic release techniques are still being pursued. We introduce a systemic arthroscopic release technique to address this special condition, in which a trans-infrapatellar fat pad release technique is developed to obtain access to the joint and to perform intra-articular and periarticular release, as well as scar tissue removal. One critical point of this technique is to create the posteromedial and posterolateral portals to re-establish the posterior compartments, remove the fibrotic posterior septum, and release the posterior capsule. This technique combines almost all related arthroscopic techniques in the treatment of knee stiffness. We consider that the introduction of this technique will provide a useful guide when surgical release is selected for this special condition.

Radiographic evaluation of the glenohumeral joint space in patients undergoing arthroscopic shoulder surgery in the beach-chair position.

Project description:BackgroundShoulder arthroscopy can be performed with the patient in the lateral decubitus or beach-chair position, but in both cases, glenohumeral (GH) joint spaces must be increased to improve visualization and allow access of the optical instrument. The aim of this study was to determine the effects of limb setup and longitudinal traction on the opening of the GH space with patients placed in the beach-chair (dorsal decubitus) position.MethodsGH spaces at 3 test points corresponding to the anatomic locations of Bankart lesions were determined indirectly from radiographic images obtained from 67 patients presenting shoulder pathology with an indication for arthroscopic surgery. Measurements were made with the operative limb in neutral rotation and positioned in relation to the coronal plane in adduction, 45° of abduction, or adduction with an axillary spacer, in each case with and without longitudinal traction.ResultsGH spaces were optimized at 2 of 3 test points when the operative limb was positioned in adduction or neutral rotation and manual longitudinal traction was applied with or without a polystyrene spacer placed under the axilla, but use of the spacer was essential to maximize the GH space at all 3 locations. In contrast, 45° of abduction proved to be the least appropriate position because it afforded the smallest GH space values with or without traction.ConclusionAppropriate positioning of the patient on the operating table is a critical aspect of shoulder arthroscopy. Radiographic images revealed that adducted upper-limb traction with the use of an axillary spacer in patients in the beach-chair position generates a significant increase in the GH space in the lower half of the glenoid cavity, thereby facilitating visualization and access of the optical equipment to the GH compartments.

Arthroscopic Coracohumeral Ligament Release for Patients With Frozen Shoulder.

Project description:Arthroscopic pancapsular release has been recommended for recalcitrant frozen shoulder, but regaining range of motion has not been sufficient compared with the unaffected side. There is no consensus about the reasons for these remaining restrictions in range of motion, but residual capsular or connective tissue must be considered a candidate. A thickened coracohumeral ligament at the rotator interval has been reported as one of the most specific manifestations of frozen shoulder. It covers wider portions of the subscapularis tendon, supraspinatus tendon, and infraspinatus tendon than previously reported. We describe an arthroscopic surgical technique for the release of the entire coracohumeral ligament including the subscapularis and supraspinatus portions and the release of the inferior and posterior parts of the glenohumeral ligament using the 7-o'clock portal. These procedures are essential and reliable methods to release the entire joint capsule to regain full range of motion for frozen shoulder.

An Arthroscopic Technique for Release of the Middle Glenohumeral Ligament and the Effect on External Rotation of the Shoulder.

Project description:The middle glenohumeral ligament (MGHL) is well recognized as a primary stabilizer of the shoulder. Its role in shoulder pathologies such as adhesive capsulitis, subscapularis tendon tear, and glenohumeral arthritis is less understood. Biomechanically, the MGHL plays an important role in range of motion, specifically involving normal and pathologic external rotation in less than 45° of abduction. In this Technical Note, we present a technique for arthroscopic release of the MGHL in the setting of a stable shoulder with preoperative loss of external rotation and a patient at risk for postoperative restriction of external rotation.

Arthroscopic Repair of Humeral Avulsion of the Glenohumeral Ligament for Anterior Shoulder Instability.

Project description:Humeral avulsion of the glenohumeral ligament (HAGL) is a rare cause of anterior shoulder instability. Recurrent instability and anterior shoulder pain could be caused by an unrepaired HAGL; therefore, making the diagnosis is crucial. Only a few articles describe arthroscopic HAGL repair. This uncommon technique uses lateral decubitus arthroscopy and standard Bankart instrumentation. Different methods used to facilitate visualization of the working space as well as anchor placements are described.

Primary Frozen Shoulder Syndrome: Arthroscopic Capsular Release.

Project description:Idiopathic adhesive capsulitis, or primary frozen shoulder syndrome, is a fairly common orthopaedic problem characterized by shoulder pain and loss of motion. In most cases, conservative treatment (6-month physical therapy program and intra-articular steroid injections) improves symptoms and restores shoulder motion. In refractory cases, arthroscopic capsular release is indicated. This surgical procedure carries several advantages over other treatment modalities. First, it provides precise and controlled release of the capsule and ligaments, reducing the risk of traumatic complications observed after forceful shoulder manipulation. Second, release of the capsule and the involved structures with a radiofrequency device delays healing, which prevents adhesion formation. Third, the technique is straightforward, and an oral postoperative steroid program decreases pain and allows for a pleasant early rehabilitation program. Fourth, the procedure is performed with the patient fully awake under an interscalene block, which boosts the patient's confidence and adherence to the physical therapy protocol. In patients with refractory primary frozen shoulder syndrome, arthroscopic capsular release emerges as a suitable option that leads to a faster and long-lasting recovery.

Inconsistency in Shoulder Arthrometers for Measuring Glenohumeral Joint Laxity: A Systematic Review.

Project description:There is no consensus on how to measure shoulder joint laxity and results reported in the literature are not well systematized for the available shoulder arthrometer devices. This systematic review aims to summarize the results of currently available shoulder arthrometers for measuring glenohumeral laxity in individuals with healthy or injured shoulders. Searches were conducted on the PubMed, EMBASE, and Web of Science databases to identify studies that measure glenohumeral laxity with arthrometer-assisted assessment. The mean and standard deviations of the laxity measurement from each study were compared based on the type of population and arthrometer used. Data were organized according to the testing characteristics. A total of 23 studies were included and comprised 1162 shoulders. Populations were divided into 401 healthy individuals, 278 athletes with asymptomatic shoulder, and 134 individuals with symptomatic shoulder. Sensors were the most used method for measuring glenohumeral laxity and stiffness. Most arthrometers applied an external force to the humeral head or superior humerus by a manual-assisted mechanism. Glenohumeral laxity and stiffness were mostly assessed in the sagittal plane. There is substantial heterogeneity in glenohumeral laxity values that is mostly related to the arthrometer used and the testing conditions. This variability can lead to inconsistent results and influence the diagnosis and treatment decision-making.

Arthroscopic Circumferential Release for Stiff Reverse Total Shoulder Arthroplasty.

Project description:Stiffness is a well-known complication after reverse shoulder arthroplasty. Although multiple factors may be involved, the main cause for stiffness is rarely identified. Imaging studies frequently are inconclusive in ruling out mechanical or biological causes. Periprosthetic infection should be always suspected, but the absence of major clinical signs and accurate diagnostic tests is frequent. A lack of objective criteria establishing a diagnosis and when to proceed with revision surgery is often present in such cases. Moreover, additional surgical procedures should be carefully evaluated, as they can represent a point of no return. Shoulder arthroscopy plays an increasingly important role in these cases, either as a diagnostic or therapeutic tool. There are no reports about arthroscopy on stiffness after reverse shoulder arthroplasty. In this Technical Note, we describe an arthroscopic technique aimed to identify potential causes of reverse shoulder arthroplasty stiffness. Subsequent circumferential release is described and discussed.

Arthroscopic Capsular Release of the Ankle Joint.

Project description:Adhesive capsulitis of the ankle is also known as frozen ankle and results in marked fibrosis and contracture of the ankle capsule. Arthroscopic capsular release is indicated for symptomatic frozen ankle that is resistant to conservative treatment. It is contraindicated for ankle stiffness due to degenerative joint disease, intra-articular malunion, or adhesion of the extensors of the ankle. The procedure consists of endoscopic posterior ankle capsulectomy and arthroscopic anterior ankle capsulotomy. It has the advantages of being minimally invasive surgery and allowing early postoperative vigorous mobilization of the ankle joint.
