Background: The inadequate arthroscopic release of the tight posterior capsule in frozen shoulder may result in limited postoperative shoulder internal rotation. Indication: The purpose of this article is to describe an L-shaped arthroscopic posterior capsular release to overcome the limited internal rotation that may be encountered following the standard longitudinal technique. Operative intervention is indicated in patients with refractory shoulder stiffness with limitation of internal rotation of grade 0, +2, +4 (according to the Constant-Murley Score), after failure of conservative measures for 3 to 6 months. The technique is contraindicated if less than 3 months of physical therapy, shoulder stiffness due to osseous deformity, infection, or cuff tear arthropathy. Technique: After performing a standard anterior capsular release, the scope is shifted to the anterior portal to perform posterior capsular release by introducing the radiofrequency ablation device through the posterior portal. Posterior release begins from the glenoid level down to the 6 o’clock position until the back fibers of the infraspinatus muscle appear. Then the hook-tip part of the radiofrequency ablation device is used to perform a transverse release in the posterior capsule, starting from the beginning of the longitudinal limb. The transverse limb is performed in a stepwise manner going step-by-step laterally but ending before reaching the rotator cuff to avoid any damage of the cuff. After that, the shoulder was manipulated according to Codman technique. Results: A comparative study was performed on 43 patients with primary frozen shoulder to compare the standard longitudinal (22 patients) and L-shaped (21 patients) posterior capsular release. At the final follow-up, there was a statistically significant improvement in the internal rotation range of motion in the L-shaped group ( P < .001). There was no loss of function over time. Moreover, there were no infections, instability, or axillary nerve injury in either group. Discussion/Conclusion: Restriction of internal rotation in frozen shoulder has been attributed to posterior capsular tightness. The L-shaped arthroscopic posterior capsular release in patients with primary frozen shoulder significantly improves the postoperative internal rotation range of motion.

Arthroscopic Capsular Release

Background: Arthroscopic capsular release has been shown to provide excellent short- and long-term outcomes in patients with idiopathic frozen shoulder. Some surgeons delay surgery in the belief that operating in the early stages of adhesive capsulitis results in a poorer prognosis. However, it is unclear which factors, particularly the stage of the disorder, affect the surgical outcome of this procedure. Hypothesis: Patients who undergo capsular release during the early symptomatic stage of idiopathic adhesive capsulitis would have less improvement in range of motion compared with those who undergo surgery at a later stage. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 189 shoulders with idiopathic adhesive capsulitis that underwent arthroscopic capsular release were evaluated. All patients completed a L’Insalata questionnaire and had their range of motion and strength tested prior to surgery and at 1, 6, and 12 weeks and 6 months post–capsular release. Post hoc, patients were grouped by whether they had symptoms lasting <10 months (shorter symptoms group; n = 131) or ≥10 months (longer symptoms group; n = 38). Multiple linear regression analysis was performed to determine which preoperative factors were independently associated with a favorable outcome. Results: Patients in the shorter symptoms group were more restricted prior to surgery than were those in the longer symptoms group (mean ± SEM: external rotation, 17° ± 2° vs 27° ± 4° [ P = .04]; abduction, 78° ± 3° vs 92° ± 6° [ P = .04]; internal rotation, S3 ± 1 vs S1 ± 1 [ P = .03]). The shorter symptoms group had greater postoperative improvement in internal rotation (from S3 ± 1 preoperatively to T12 ± 1 vertebral levels) compared with the longer symptoms cohort (from S1 ± 1 to L2 ± 1) ( P = .02). Conclusion: Patients with a frozen shoulder and a duration of symptoms <10 months made greater improvements in internal rotation and had similar final results for flexion, abduction, and external rotation following arthroscopic capsular release when compared with patients who had a longer duration of symptoms, so there is no reason to delay surgery.

BACKGROUND: Persisting shoulder stiffness adversely affects quality of life by causing pain and motion restrictions especially in patients with diabetes. OBJECTIVE: The aim of this study was to evaluate the outcomes of arthroscopic capsular release in patients with idiopathic shoulder stiffness. METHOD: A literature search was conducted in electronic databases and studies were selected by following precise eligibility criteria. Random-effects meta-analyses were performed to estimate the changes at latest follow-up in scores of the Constant, American Shoulder and Elbow Surgeons (ASES), and University of California at Los Angelis (UCLA) scales, Visual Analogue Scale (VAS), and shoulder range of motion. RESULTS: Nineteen studies were included. The follow-up duration was 42 months [95% confidence interval (CI): 32, 51]. Improvements in scores of the Constant, ASES, UCLA scales, and VAS were 48.3 [95% CI: 38.0, 58.6], 44.6 [95% CI: 24.6, 64.6], 19.3 [95% CI: 16.6, 22.0], and -6.1 [95% CI: -6.9, -5.4] respectively (P< 0.05 all). Improvements in the shoulder range of motion were: abduction 82.0 [95% CI: 65.0, 98.9]; forward flexion 75.9 [95% CI: 59.7, 92.1]; external rotation 43.2 [95% CI: 37.5, 49.0]; and internal rotation 25.4 [95% CI: 15.2, 35.5] degrees; P< 0.05 all). CONCLUSION: Arthroscopic capsular release effectively improves shoulder function in patients with idiopathic shoulder stiffness.

INTRODUCTION The aim of this prospective study was to assess the immediate and long-term effectiveness of arthroscopic capsular release in a large cohort of patients with a precise and isolated diagnosis of stage II idiopathic frozen shoulder. METHODS All patients underwent a preoperative evaluation. Patients with secondary frozen shoulder and those with concurrent pathology at arthroscopy were excluded. This left 136 patients with a stage II arthroscopically confirmed idiopathic frozen shoulder. At each postoperative attendance, a record was made of pain, function and range of motion. At 12 months, the Oxford shoulder score was calculated, and pain and range of motion were assessed. RESULTS Fifty per cent achieved good pain relief within a week and eighty per cent within six weeks of arthroscopic capsular release. The mean preoperative visual analogue scale pain score was 6.6 and the mean postoperative score was 1.0. The mean time to achieving good pain relief was 16 days following surgery. No patient could sleep through the night prior to surgery while 90% reported having a complete night’s sleep at a mean of 12 days after surgery. The mean postoperative Oxford shoulder score was 38/48 and the mean improvement was 19.2. CONCLUSIONS This large series demonstrates that arthroscopic capsular release is a safe procedure, with rapid improvement in pain and a marked improvement in range of motion.

Glenohumeral joint posterior capsule contracture may cause shoulder pain by altering normal joint mechanics. Contracture is commonly noted in throwing athletes but can also be present in nonthrowers. The cause of contracture in throwing athletes is assumed to be a response to the high amount of repetitive tensile force placed on the tissue, whereas the mechanism of contracture in nonthrowers is unknown. It is likely that mechanical and cellular processes interact to increase the stiffness and decrease the compliance of the capsule, although the exact processes that cause a contracture have not been confirmed. Cadaver models have been used to study the effect of posterior capsule contracture on joint mechanics and demonstrate alterations in range of motion and in humeral head kinematics. Imaging has been used to assess posterior capsule contracture, although standard techniques and quantification methods are lacking. Clinically, contracture manifests as a reduction in glenohumeral internal rotation and/or cross body adduction range of motion. Stretching and manual techniques are used to improve range of motion and often decrease symptoms in painful shoulders.

Background Adhesive capsulitis (frozen shoulder) is characterised by pain and loss of range of motion of the glenohumeral joint. It can be present as primary (idiopathic) or secondary to surgery, trauma or other conditions that restrict the use of the shoulder joint. Various treatment options have been adopted including physiotherapy, manipulation under anaesthetic, hydrodilatation and arthroscopic or open capsular release but the optimal form of management remains uncertain. Objectives The purpose of the study was to assess the clinical outcome of glenohumeral hydrodilatation in three cohorts of patients with different aetiologies with adhesive capsulitis. Study design & methods We carried out a retrospective study of patient who underwent hydrodilatation for adhesive capsulitis between 2013 and 2015. The procedure was performed by a specialist musculoskeletal radiologist under radiological guidance. The injection consisted of steroids, local anaesthetics and NaCl solution with a target volume around 35 mL. Our outcome measures were range of motion, and pre- and post-operative pain. Patients were divided into three groups based on the presumed cause of their stiffness: idiopathic, post-traumatic and post-surgical. Results Two hundred fifty patients were included, with a mean age of 59 years (range: 20–79). Of these, 180 had idiopathic primary adhesive capsulitis (27 were diabetic), 23 were post-traumatic, and 20 following surgical procedures. Thirty-four required further intervention following initial hydrodilatation with 8 undergoing repeat hydrodilatation, and 26 requiring arthroscopic capsular release. The diabetic group accounted for 16 capsular releases and 4 repeat procedures, while the idiopathic group accounted for 9 and 4, respectively. One patient required capsular release in the surgical group. An improvement was recorded in ROM in all groups with mean abduction improving from 59° to 110°, flexion from 50° to 120° and external rotation from 20° to 50°. With regards to pain, the majority showed an improvement from severe or moderate pain to no or mild pain. Conclusions Results show that hydrodilatation resulted in an improvement in all outcome measures, with only a small number of patients, especially those with diabetes, needing further procedures or showing no improvement in range of motion and pain. There was no difference between the post-traumatic and post-surgical groups.

Background: Altered glenohumeral joint range of motion can be caused by increased humeral retroversion (HR) and/or posterior capsule tightness (PCT). To make informed clinical decisions, it is vital to understand how HR and PCT alterations, individually and in combination, affect joint range of motion measurements. Purpose: To evaluate the effect of experimental tissue alterations on clinical range of motion measures. Study Design: Controlled laboratory study. Methods: Five clinical measurements were quantified in 8 fresh-frozen cadavers under 4 experimentally created conditions: baseline (no alterations), HR condition (20° increase in HR by transecting the bone), PCT condition (20% decrease in length via thermal energy), and PCT + HR combined. Clinical measurements included bicipital forearm angle, low flexion, glenohumeral internal and external rotation, and horizontal adduction. All measurements were taken by the same blinded tester. Separate 1-factor repeated measures analyses of variance were used to evaluate the effect of the alterations on each clinical measurement. Results: There was a significant main effect of condition for bicipital forearm angle ( P = .02, F = 4.03), low flexion ( P = .02, F = 3.86), internal rotation ( P = .03, F = 3.65), and external rotation ( P < .001, F = 15.15) but not for horizontal adduction ( P = .29, F = 1.33). The HR condition resulted in a decreased bicipital forearm angle of 16.1° and 15.8° as compared with the PCT and PCT + HR conditions, respectively. When compared with baseline, the PCT + HR condition decreased the low flexion test by 13.5°, and the HR condition decreased internal rotation range of motion by 14.2°. All conditions increased external rotation when compared with baseline. Conclusion: Greater measurement changes were noted in both HR conditions, suggesting that bony alterations influence motion to a greater extent than posterior capsule alterations. Clinical Relevance: Clinicians should be aware that humeral retroversion will influence the measurement of posterior shoulder tightness.

Overhead Throwing

Context The high number of repetitions and high forces associated with overhead throwing lead to anatomical adaptations, such as humeral retrotorsion and posterior-capsule thickness, in elite and professional baseball athletes. However, little is known about the origin and progression of these changes that may account for the increasing trend of chronic shoulder injuries in youth baseball and precipitate subsequent pathologic conditions throughout a young athlete's lifetime. Objective To investigate the relationship of age and upper extremity dominance on humeral retrotorsion, posterior-capsule thickness, and glenohumeral range of motion. Design Cross-sectional study. Setting Research laboratory, local baseball fields, and training facilities. Patients or Other Participants Thirty-six boys (mean age = 10.94 ± 1.34 years, height = 151.31 ± 12.17 cm, mass = 42.51 ± 10.32 kg) ranging in age from 8 to 12 years and involved in organized youth baseball. Main Outcome Measure(s) Diagnostic ultrasound was used to determine humeral retrotorsion and posterior-capsule thickness. Glenohumeral internal rotation and external rotation were measured using a handheld inclinometer. We used 2 × 2 mixed-model analyses of variance to compare the influence of limb dominance and age on the dependent variables of humeral retrotorsion, posterior-capsule thickness, internal rotation, and external rotation. Results The dominant shoulders of youth throwers exhibited less glenohumeral internal rotation but greater humeral retrotorsion, posterior-capsule thickness, and glenohumeral external rotation than the nondominant shoulders. Dominant internal rotation was greater in the 8- to 10-year-old group than in the 11- to 12-year-old group, and results trended toward a difference (F1,33 = 4.12, P = .05). Correlations existed between humeral retrotorsion and range of motion (P &lt; .05). Conclusions The structural adaptations in the dominant shoulders of younger baseball players were similar to adaptations observed in older baseball athletes, indicating that more examination is needed in younger athletes. We are the first to demonstrate greater posterior-capsule thickness in the dominant shoulders of youth baseball athletes.

Background: Arthroscopic capsular release is an effective treatment for refractory shoulder stiffness, yet there are no basic studies that can explain the extent of the release. Purpose: This study aimed to compare the genetic expression of inflammation- and fibrosis-related factors between the anterior and posterior capsules in patients with shoulder stiffness and rotator cuff tear. Study Design: Descriptive laboratory study. Methods: Enrolled in this study were 35 patients who underwent arthroscopic capsular release for shoulder stiffness along with the rotator cuff repair. Anterior and posterior glenohumeral joint capsular tissues were obtained during the capsular release. For the control tissue, anterior capsule was obtained from 40 patients without stiffness who underwent arthroscopic rotator cuff repair. The gene expression of collagen types I and III, fibronectin, extracellular matrix, basic fibroblast growth factor, transforming growth factor–β, connective tissue growth factor, matrix metalloproteinase (MMP)-1, MMP-2, MMP-9, tissue inhibitor of metalloproteinase (TIMP)-1, TIMP-2, intercellular adhesion molecule 1, interleukin 1, and tumor necrotizing factor–α were analyzed using real-time reverse transcription polymerase chain reaction. Differences in gene expression between the anterior capsule, the posterior capsule, and the control tissue were compared with the Kruskal-Wallis test. Results: The expression levels of collagen types I and III were significantly higher in the anterior capsule with stiffness com (pared with both the posterior capsule with stiffness ( P = .010 for both) and the control ( P = .038 and .010, respectively). The levels of fibronectin, MMP-2, and MMP-9 in the anterior capsule were significantly higher than in both the posterior capsule ( P = .013, .003, and .006, respectively) and the control ( P = .014, .003, and .005, respectively). Conclusion: Genetic analysis of the shoulder capsule revealed that more fibrogenic processes occur in the anterior capsule compared with the posterior capsule in patients with shoulder stiffness. Clinical Relevance: Capsular release for shoulder stiffness should be more focused on the anterior capsule than on the posterior capsule.
