Intraarticular lesions in primary frozen shoulder after manipulation under general anesthesia

Predictors of outcome after nonoperative and operative treatment of adhesive capsulitis

BACKGROUND

Few studies regarding adhesive capsulitis have concurrently evaluated nonoperative and operative treatment.

PURPOSE

The objectives were to evaluate the efficacy of operative and nonoperative treatment of adhesive capsulitis and to determine predictors of clinical outcome.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

At minimum 24 months' follow-up, 85 patients underwent self-assessment using the Simple Shoulder Test (SST) and American Shoulder and Elbow Surgeons (ASES) score, including 24 patients treated operatively.

RESULTS

Mean number of yes responses on the SST improved from 4.0 ± 2.7 at initial presentation to 9.9 ± 2.8 at final follow-up (P < .0001). Patients who received nonoperative treatment and patients who underwent surgery demonstrated similar improvements on the SST. For the entire cohort, forward elevation and external rotation at the side improved from 119° ± 20° to 152° ± 15° and from 29° ± 18° to 46° ± 11° (P < .0001), respectively, between initial presentation and discharge from treatment. Internal rotation to the back improved from the gluteal area to the thoracolumbar junction (P < .0001). Improvements in forward elevation and external rotation were greater for patients undergoing surgery. After nonoperative treatment, patients with diabetes had a lower final SST than patients without diabetes (P < .05). For the entire cohort, initial SST predicted final SST (P < .05), and a shorter duration of symptoms predicted a higher final ASES score (P < .05). Younger patients (P < .001) and those with a lower initial SST (P < .05) were more likely to undergo surgery.

CONCLUSIONS

A multimodal nonoperative treatment program is effective for most patients with adhesive capsulitis. Patients who do not improve, including those with diabetes, respond well to manipulation and arthroscopic release. Residual motion deficits at discharge from treatment do not appear to affect longer-term clinical outcome.

Adhesive capsulitis: a review of current treatment

Adhesive capsulitis is characterized by a painful, gradual loss of both active and passive glenohumeral motion resulting from progressive fibrosis and ultimate contracture of the glenohumeral joint capsule. Variable nomenclature, inconsistent reporting of disease staging, and a multitude of different treatments have created a confusing and contradictory body of literature about this condition. Our purpose is to review the evidence for both nonsurgical and surgical management of adhesive capsulitis with an emphasis on level I and II studies when available. Significant deficits in the literature include a paucity of randomized controlled trials, failure to report response to treatment in a stage-based fashion, and an incomplete understanding of the disease's natural course. Recognition that the clinical stages reflect a progression in the underlying pathological changes should guide future treatments.

Is the extended release of the inferior glenohumeral ligament necessary for frozen shoulder?

PURPOSE

The aims of our study were to assess effects of the extent of capsular release and to define the benefit of additional release of the inferior glenohumeral ligament (IGHL) from inferior to posterior in frozen shoulder.

METHODS

Seventy-four consecutive patients with refractory frozen shoulder underwent arthroscopic capsular release and were divided into 2 groups randomly. The release of anterior capsular structures, including the anterior band of the IGHL, was performed in group 1. In group 2 the release extended inferiorly and posteriorly. Constant functional scores were used to assess the outcome. The range of motion (ROM) in various directions was also recorded preoperatively and postoperatively.

RESULTS

Follow-up was obtained in 41 patients in group 1 and 29 patients in group 2, and it averaged 28 months. At the last follow-up, there was a significant improvement in Constant score (P < .01) postoperatively in all patients. There was a significant and rapid reduction in the visual analog scale score in both groups postoperatively. No statistical difference in the visual analog scale score was found between the 2 groups at the corresponding time points. Overall, patients had restored shoulder ROM at the last follow-up without difference between group 1 and group 2. Abduction, flexion, external rotation at 90 degrees of abduction, internal rotation at 0 degrees of abduction, and internal rotation at 90 degrees of abduction recovered more rapidly in group 2 within 3 months after surgery; however, there was no significant difference in ROM after 6 months.

CONCLUSIONS

In this broad group of patients with recalcitrant adhesive capsulitis, the addition of the posterior capsular release did not improve patient function or ROM over anterior capsular release alone at 6 months. The extended release of the inferior and posterior IGHL would improve ROM more rapidly within the first 3 months postoperatively.

Frozen shoulder: a clinical review

Frozen shoulder is a common condition which can cause considerable morbidity for a prolonged duration. With recognition of the condition's time scale, management can be directed to help reduce the morbidity. Many treatments are recognized and the gold standard is still to be identified.

Manipulation or intra-articular steroids in the management of adhesive capsulitis of the shoulder? A prospective randomized trial

BACKGROUND

The management of adhesive capsulitis (frozen shoulder) is controversial. The authors present a prospective randomized study comparing the outcome, at a two-year follow-up period, of two groups of patients treated either by manipulation of the shoulder under anaesthetic or by intra-articular shoulder injections using steroid with distension.

METHODS

Fifty-three patients suffering from Idiopathic "Primary" Frozen Shoulder were prospectively randomized into two treatment groups and followed up for two years from the start of treatment. Patients were assessed using the Constant score, a Visual Analogue Score, and the SF36 questionnaire.

RESULTS

No statistical differences were found between the two groups of patients with regards to the outcome measures.

CONCLUSION

Treatment using steroid injections with distension as an out-patient is therefore recommended for the treatment of Idiopathic "Primary" Frozen Shoulder. This has the same clinical outcome as a manipulation under anaesthetic with less attendant risks.

[Frozen shoulder. Diagnosis and therapy]

The condition of shoulder stiffness is often called adhesive capsulitis or frozen shoulder. It is regarded as a distinct clinical entity showing a benign and regular course. The major clinical feature is significant reduction in both active and passive range of motion (ROM) accompanied by stage-dependent pain, allowing for a clinical diagnosis. There are primary and secondary forms, the former having an unknown etiology and increased occurrence in patients with metabolic disorders and the latter being seen with prior injury or operation. Three stages, each lasting 4-6 months, mark the clinical course. The progression of the disease is self-limiting and may occasionally resolve in partial restitution. In the first stage ("freezing"), the shoulder continuously loses passive motion and causes worsening pain. Continuing stiffness and improvements in pain and inflammation are characteristic of the second stage ("frozen"). In the third stage ("thawing"), restriction of shoulder motion decreases, and ROM increases. Treatment should be adjusted to these stages. Recommendations include analgesics and joint injections in the first stage and physiotherapy in combination with manual therapy in the second and third stages. In cases of failure, passive exercise under interscalene block, manipulation under general anesthesia, or arthroscopic arthrolysis should be considered.

Frozen shoulder: evidence and a proposed model guiding rehabilitation

Frozen shoulder or adhesive capsulitis describes the common shoulder condition characterized by painful and limited active and passive range of motion. The etiology of frozen shoulder remains unclear; however, patients typically demonstrate a characteristic history, clinical presentation, and recovery. A classification schema is described, in which primary frozen shoulder and idiopathic adhesive capsulitis are considered identical and not associated with a systemic condition or history of injury. Secondary frozen shoulder is defined by 3 subcategories: systemic, extrinsic, and intrinsic. We also propose another classification system based on the patient's irritability level (low, moderate, and high), that we believe is helpful when making clinical decisions regarding rehabilitation intervention. Nonoperative interventions include patient education, modalities, stretching exercises, joint mobilization, and corticosteroid injections. Glenohumeral intra-articular corticosteroid injections, exercise, and joint mobilization all result in improved short- and long-term outcomes. However, there is strong evidence that glenohumeral intra-articular corticosteroid injections have a significantly greater 4- to 6-week beneficial effect compared to other forms of treatment. A rehabilitation model based on evidence and intervention strategies matched with irritability levels is proposed. Exercise and manual techniques are progressed as the patient's irritability reduces. Response to treatment is based on significant pain relief, improved satisfaction, and return of functional motion. Patients who do not respond or worsen should be referred for an intra-articular corticosteroid injection. Patients who have recalcitrant symptoms and disabling pain may respond to either standard or translational manipulation under anesthesia or arthroscopic release.

The influence of arthroscopic subscapularis tendon and capsule release on internal rotation strength in treatment of frozen shoulder

BACKGROUND

Arthroscopic release of the capsule is a popular treatment option for chronic refractory frozen shoulder. Additional release of the intra-articular part of the subscapularis is controversial regarding possible impairment of subscapularis function.

HYPOTHESIS

Arthroscopic release of the intra-articular part of the subscapularis produces good clinical results and does not lead to reduced internal rotation strength.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

Twenty-two patients were retrospectively evaluated 53 months (range, 12-106) after undergoing arthroscopic anterior capsular release, including release of the intra-articular portion of the subscapularis. Clinical outcome was evaluated using the American Shoulder and Elbow Surgeons score and the Constant score. Isometric and isokinetic strength for internal and external rotation were determined at the time of follow-up in both shoulders using a Cybex dynamometer.

RESULTS

The Constant score was improved significantly from 17.7 points to 82.8 points (P < .0001) and the American Shoulder and Elbow Surgeons score increased significantly from 23.5 points to 76.8 points (P < .0001). The mean range of motion was significantly improved for external rotation from 16 degrees to 58 degrees , from 66 degrees to 142 degrees for abduction, and from 76 degrees to 155 degrees for forward flexion. Isometric and isokinetic strength in the standard abduction position of the Cybex dynamometer showed no significant side-to-side difference.

CONCLUSION

Arthroscopic capsular release combined with a release of the intra-articular portion of the subscapularis tendon revealed good clinical results in the arthroscopic treatment of adhesive capsulitis without significant loss of internal rotation strength.

Manipulation under anesthesia with home exercises versus home exercises alone in the treatment of frozen shoulder: a randomized, controlled trial with 125 patients

We aimed to determine the effect of manipulation under anesthesia in frozen shoulder patients. A blinded randomized trial with a 1-year follow-up was performed at 3 referral hospitals in Southern Finland. We randomly assigned 125 patients with clinically verified frozen shoulder to the manipulation group (n = 65) or control group (n = 60). Both the intervention group and the control group were instructed in specific therapeutic exercises by physiotherapists. Clinical data were gathered at baseline and at 6 weeks and 3, 6, and 12 months after randomization. The 2 groups did not differ at any time of the follow-up in terms of shoulder pain or working ability. Small differences in the range of movement were detected in favor of the manipulation group. Perceived shoulder pain decreased during follow-up equally in the 2 groups, and at 1 year after randomization, only slight pain remained. Manipulation under anesthesia does not add effectiveness to an exercise program carried out by the patient after instruction.

Idiopathic adhesive capsulitis of the shoulder: a review

Many terms have been used to describe what has been called idiopathic adhesive capsulitis of the shoulder. This pathology is defined as a self-limiting condition of unknown etiology. The natural history is 18-30 months even though a high-percentage of patient present impaired range of movement even at long-term follow-up. The diagnosis is mainly clinical and no significant changes are normally present at MRI or CT scan. Several treatment options have been tried over the years with different approaches and results.

Hydrodilatation (distension arthrography): a long-term clinical outcome series

OBJECTIVES

To describe and compare the medium to long-term effectiveness of hydrodilatation and post-hydrodilatation physiotherapy in patients with primary and secondary glenohumeral joint contracture associated with rotator cuff pathology.

METHODS

Patients with primary and secondary glenohumeral contractures associated with rotator cuff pathology were recruited into a 2-year study. They all underwent hydrodilatation, followed by a structured physiotherapy programme. Patients were assessed at baseline, 3 days, 1 week, 3 months, 1 year and 2 years after hydrodilatation with primary outcome measures (Shoulder Pain and Disability Index, Shoulder Disability Index and percentage rating of "normal" function; SD%) and secondary outcome measures (range of shoulder abduction, external rotation and hand behind back). Comparisons in recovery were made between the primary and secondary glenohumeral contracture groups at all timeframes and for all outcome measures.

RESULTS

A total of 53 patients (23 with primary and 30 with secondary glenohumeral contractures) were recruited into the study. At the 2-year follow-up, 12 patients dropped out from the study. At baseline, the two contracture groups were similar with respect to their demographic and physical characteristics. The two groups of patients recovered in a similar fashion over the 2-year follow-up period. A significant improvement was observed in all outcomes measures over this period (p<0.01), so that both function and range of movement increased. The rate of improvement was dependent on the outcome measure that was used.

CONCLUSIONS

Hydrodilatation and physiotherapy increase shoulder motion in individuals with primary and secondary glenohumeral joint contracture associated with rotator cuff pathology. This benefit continues to improve or is maintained in the long term, up to 2 years after hydrodilatation.

The effect of anterior versus posterior glide joint mobilization on external rotation range of motion in patients with shoulder adhesive capsulitis

STUDY DESIGN

Randomized clinical trial.

OBJECTIVE

To compare the effectiveness of anterior versus posterior glide mobilization techniques for improving shoulder external rotation range of motion (ROM) in patients with adhesive capsulitis.

BACKGROUND

Physical therapists use joint mobilization techniques to treat motion impairments in patients with adhesive capsulitis. However, opinions of the value of anterior versus posterior mobilization procedures to improve external rotation ROM differ.

METHODS AND MEASURES

Twenty consecutive subjects with a primary diagnosis of shoulder adhesive capsulitis and exhibiting a specific external rotation ROM deficit were randomly assigned to 1 of 2 treatment groups. All subjects received 6 therapy sessions consisting of application of therapeutic ultrasound, joint mobilization, and upper-body ergometer exercise. Treatment differed between groups in the direction of the mobilization technique performed. Shoulder external rotation ROM measured initially and after each treatment session was compared within and between groups and analyzed using a 2-way ANOVA, followed by paired and independent t tests.

RESULTS

There was no significant difference in shoulder external rotation ROM between groups prior to initiating the treatment program. A significant difference between groups (P = .001) was present by the third treatment. The individuals in the anterior mobilization group had a mean improvement in external rotation ROM of 3.0 degrees (SD, 10.8 degrees; P = .40), whereas the individuals in the posterior mobilization group had a mean improvement of 31.3 degrees (SD, 7.4 degrees; P < .001).

CONCLUSIONS

A posteriorly directed joint mobilization technique was more effective than an anteriorly directed mobilization technique for improving external rotation ROM in subjects with adhesive capsulitis. Both groups had a significant decrease in pain.

Capsulite de l'épaule : évaluation d'une prise en charge combinée par arthrodistension et rééducation intensive (à propos d'une série de 39 épaules)

INTRODUCTION

Adhesive capsulitis is a clinical entity characterized by a loss of motion and a decrease of the joint volume capacity. Results of clinical trials have shown that distensions can help to decrease pain and increase the range of motion.

OBJECTIVE

The purpose of the study was to measure the effect of repeated distension arthrography combined with an intensive program of rehabilitation on pain, range of motion, and occupational outcome in patients with adhesive capsulitis.

DESIGN

39 cases of idiopathic capsulitis (7 cases) or secondary capsulitis (19 post-traumatic, 13 post-surgery of the rotator cuff) were included in the study. Intervention consisted of an intensive program of passive and active physiotherapy during one? Week and then distension arthrography, performed 3 times at 1- week intervals, with steroid injections in the glenohumeral joint and 1 in the subacromial space.

RESULTS

Lateral elevation improved substantially after the first week of physiotherapy and medial rotation after the first distension. Pain intensity decreased after the first distension. After the third distension, very small changes were noted. Results did not differ by etiology of capsulitis. At the end of the program, 9 of 17 patients could return to their previous job.

CONCLUSIONS

Two repeated arthrographic distensions with steroid injection and an intensive program of physiotherapy improves the range of motion and the painful condition associated with capsulitis and allows for a rapid return to employment. A third distension does not seem to provide a further benefit, as has been found by other studies.
