Arthroscopic Coracohumeral Ligament Release for Patients With Frozen Shoulder.

ABSTRACT: 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.

Clinical outcomes of arthroscopic pan-capsular release with or without entire coracohumeral ligament release for patients with frozen shoulder.

Project description:BackgroundWe aimed to retrospectively determine the effects of arthroscopic pan-capsular release with or without entire coracohumeral ligament (CHL) release and diabetes mellitus (DM) in patients with frozen shoulder (FS).MethodsThe study included 34 patients (20 male and 14 female patients) who underwent arthroscopic pan-capsular release without entire CHL release (group 1) and 26 patients (6 male and 20 female patients) who underwent entire CHL release for FS (group 2). Patients with a minimum of 12 months of follow-up were included, and range of motion (ROM) and the shoulder rating scale of the University of California at Los Angeles (UCLA) scoring system were evaluated.ResultsIn group 2, external rotation and hand-behind-the-back (HBB) ROMs were significantly increased compared with group 1 at the final follow-up (external rotation, 53.1° ± 15.2° vs. 41.3° ± 20.5° [P = .044]; HBB level, T6 [interquartile range, T5-T9] vs. T11 [interquartile range, T8-L4] [P < .001]). Total UCLA scores and UCLA scores for pain (9.2 ± 1.5 vs. 10.0, P = .003), function (8.5 ± 1.4 vs. 10.0, P < .001), and active forward flexion (4.6 ± 0.6 vs. 4.9 ± 0.2, P < .011) were significantly greater in group 2 at the final follow-up. Patients without DM tended to have greater recovery of forward flexion and HBB ROMs and better total, pain, and function UCLA scores compared with those with DM. In group 2, there were no significant differences in ROMs and UCLA scores between the patients with DM and those without DM.ConclusionArthroscopic entire CHL release is an essential treatment option for FS patients to regain ROMs and function and to reduce pain.

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.

Coracohumeral Ligament Reconstruction for Patients With Multidirectional Shoulder Instability.

Project description:Coracohumeral ligament pathology arises from acute trauma, capsular thickening, or congenital connective tissue disorders within the glenohumeral joint. Recent studies have highlighted the significance of this pathology in multidirectional shoulder instability because insufficiency of the rotator interval has become increasingly recognized and attributed to failed shoulder stabilization procedures. The diagnosis and subsequent treatment of coracohumeral ligament pathology can be challenging, however, because patients usually present with a history of failed surgical stabilization and persistent laxity. At the time of presentation, most patients have undergone failed nonoperative treatments and are indicated for surgical intervention. One of the options for the treatment of coracohumeral ligament pathology is reconstruction. The purpose of this Technical Note is to describe our preferred surgical technique for the reconstruction of the coracohumeral ligament. Research was performed at the Steadman Philippon Research Institute.

Arthroscopic release for frozen shoulder: Does the timing of intervention and diabetes affect outcome?

Project description:PURPOSE:To evaluate the effect of timing of arthroscopic release and manipulation under anesthesia for frozen shoulder in patients with diabetes and non-diabetes. METHODS:One hundred and twenty-seven patients with frozen shoulder were included in the study. Each patient was assigned to: 1) one of four groups according to the duration from symptom onset to surgery (group A: ?3 months; group B: 3-6 months; group C: 6-12 months; group D: >12 months), 2) diabetic or nondiabetic group. The outcomes were measured by shoulder range of motion (ROM), Disabilities of the Arm, Shoulder, and Hand (DASH) score, American Shoulder and Elbow Surgeons (ASES) Shoulder score, the period of pain relief, overall duration of disease, and satisfaction. RESULTS:All the patients got great improvement in shoulder ROM (P < .0001) after arthroscopic surgery, but there was no statistical difference in the pre-operative and post-operative shoulder ROM between the four groups and between diabetic and nondiabetic groups. The overall duration of disease was mean 55.4~68.7 weeks, which demonstrated much shorter disease course compared with nature course. Improvement were also seen in shoulder ROM at one week to one month, and the period of total pain relief was at a mean time of 3.7 to 3.8 weeks. There were higher ASES Shoulder score in group B than in group C (P = 0.02) and higher DASH score in diabetic group in short term follow-up. CONCLUSIONS:Arthroscopic release provides effective and rapid improvements to shoulder motion and function, unrelated to the timing of surgery, in patients with frozen shoulder. The diabetic patients do not have functional outcomes as good as the nondiabetic patient at short-term follow-up.

Dynamic Analysis of the Coracohumeral Ligament Using Ultra-Sonography in Shoulder Contracture.

Project description:The coracohumeral ligament (CHL) is related to the range of motion of the shoulder joint. The evaluation of the CHL using ultrasonography (US) has been reported on the elastic modulus and thickness of the CHL, but no dynamic evaluation method has been established. We aimed to quantify the movement of the CHL by applying Particle Image Velocimetry (PIV), a technique used in the field of fluid engineering, to cases of shoulder contracture using the US. The subjects were eight patients, with 16 shoulders. The coracoid process was identified from the body surface, and a long-axis US image of the CHL parallel to the subscapularis tendon was drawn. The shoulder joint was moved from 0 degrees of internal/external rotation to 60 degrees of internal rotation at a rhythm of one reciprocation every 2 s. The velocity of the CHL movement was quantified by the PIV method. The mean magnitude velocity of CHL was significantly faster on the healthy side. The maximum magnitude velocity was significantly faster on the healthy side. The results suggest that the PIV method is helpful as a dynamic evaluation method, and in patients with shoulder contracture, the CHL velocity was significantly decreased.

The Angular Relationships Between the Coracohumeral Ligament and Adjacent Shoulder Structures Are Variable.

Project description:PurposeTo describe the arthroscopic anatomy of the coracohumeral ligament (CHL) in relation to visible anatomic reference points to aid in the execution of a more effective arthroscopic medial-lateral rotator interval closure.MethodsDetailed dissection to identify the CHL was performed in 4 shoulders from 2 fresh-frozen donor cadavers with a deltopectoral approach. The angular relationship between the CHL and the superior border of the subscapularis tendon was determined via gross dissection. Arthroscopic images were used to determine the angular position of the CHL in relation to both the glenoid articular surface and the intraarticular segment of the tendon of the long head of the biceps brachii (LHB).ResultsAnalysis of 4 cadaveric shoulders via gross dissection demonstrated the CHL to subtend a mean angle of 29° (range 16° to 39°) with respect to the superior border of the subscapularis tendon. Arthroscopic analysis of 4 cadaveric shoulders demonstrated the CHL to subtend a mean angle of 59° (range 38° to 77°) with respect to the glenoid articular surface. Additionally, arthroscopic analysis of 2 cadaveric shoulders demonstrated the CHL to subtend a mean angle of 29° (range 11° to 47°) with respect to the LHB tendon.ConclusionAlthough the position of the CHL in relation to the subscapularis tendon, glenoid articular surface, and LHB tendon demonstrates a moderate degree of anatomic variability, these structures provide valuable anatomic reference points for the identification of the course of this significant static shoulder stabilizer.Clinical relevanceComprehensive understanding of the angular relationships between the CHL and adjacent shoulder structures may assist with the execution of a more effective arthroscopic rotator interval closure.

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

Project description: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.

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.
