Adhesive Capsulitis

noemail@drgartsman.com — Fri, 17 Jun 2005 21:00:00 GMT

I feel that the cause of your pain is a condition called Adhesive Capsulitis or Frozen Shoulder. This is a common shoulder problem that affects thousands of people every year. We do not know the cause of frozen shoulder. It does not seem to result from an injury. While some people relate the onset of their pain to an injury or illness, many more say the problem began out of the blue, without any cause. Pain may start suddenly or begin slowly. Pain and stiffness in the shoulder increase. Often patients report difficulty with sleep as the shoulder is particularly painful at night. Reaching up to get items off shelves, reaching behind the back to tuck in a shirt or blouse become difficult or impossible. Adhesive capsulitis is not a disease or aging. Most patients are between the ages of 40 and 60. The condition does not increase as you get older. Let me emphasize that this is a condition, not an injury. Like any condition it has a beginning, a middle and an end. You know the...

Radiographic comparison of pegged and keeled glenoid

Wed, 18 May 2005 22:00:00 GMT

Glenoid loosening is one reason for failure of tota shoulder arthroplasty. Several factors, including radiographic lucency, have been shown to be associated with glenoid loosening. The purpose of this study was to assess the correlation between glenoid design and immediate radiographic lucency in a prospective randomized clinical trial. Total shoulder arthroplasty was performed in 43 patients over a 2-year period. Twenty-three patients were randomized into the keel group and twenty patients into the pegged group. Postoperative radiographs obtained within 6 weeks of surgery were evaluated by 3 raters to determine glenoid lucency. On a scale from 0 (no lucency) to 5 (gross lucency and component loosening), the rate of lucency was 39% (9/23) in the keeled components, which was significantly higher than the rate of 5% (1/20) observed in the pegged components (P = .026). Patient age, gender,and glenoid size did not significantly affect glenoid component lucency (P > .05). The consistency reliability among raters was 0.87,and the intertester reliability was 0.87. Pegged glenoid components have less radiographic lucency when compared with keeled glenoid components in the immediate postoperative period. (J Shoulder Elbow Surg 2005;14:252-257.)

The relationship among strength and mobility measures and self-report outcome scores in persons after rotator cuff repair surgery:Impairment measures are not enough

Thu, 31 Mar 2005 13:00:00 GMT

Until recently, few investigators challenged the pre-vailing medical view of health. Medicine perceived health as an observable, biologic fact, and the goal of medical assessment was to objectively evaluate the body’s status. Because patient reports of health status are subjective, they were considered unreliable and unscientific. The use of self-reports to evaluate health and health outcomes, however, has burgeoned in the last 10 to 20 years, as has the authority assigned to patients’ evaluations. Sullivan 14 described this move toward a “new subjective medicine” as a change in medicine’s focus from patients’ bodies to patients’ lives. In the current milieu, self-reported perceptions of health, function, and health-related quality of life (of-ten called patient-centered outcomes) are prominent. These outcomes have authority not in spite of their subjectivity but because of their subjectivity. The inter-est of health policy agents and third-party insurers in health care value and cost-effectiveness may have been at the root of the shift toward patient-centered outcomes.14

Development of a Flexilevel Scale for use with computer adaptive testing for assessing shoulder function

Tue, 01 Feb 2005 14:45:00 GMT

In a 5-year study, a self-report measure of shoulder function—the Flexilevel Scale of Shoulder Function (FLEX-SF)—was developed by use of item response the-ory. A large pool of candidate items (N 68) was developed. A questionnaire that included the 68 items, another scale of shoulder function, and clinical and demographic questions were administered to 400 per-sons with shoulder complaints. Patients’ responses to the 68 items were calibrated by use of Andrich’s rat-ing scale model. Thirty-three items were selected from the pool and subdivided into three overlapping testlets targeting low, medium, and high shoulder function. A table translates raw scores on testlets to a common mathematical metric. The validity and reliability of the FLEX-SF was evaluated in a longitudinal study of 199 patients. The FLEX-SF scores were highly reliable and exhibited excellent validity (including responsiveness). We report on a simulation of a computer-adaptive test of shoulder function. This simulation is based on the developmental items we tested for use in the FLEX-SF. The results indicate that greater measurement effi-ciency can be achieved with a computer-adaptive test format.

Arthroscopic rotator cuff repair with and without arthroscopic subacromial decompression: A prospective, randomized study of one-year outcomes

Tue, 31 Aug 2004 14:00:00 GMT

All other aspects of the surgical and postsurgical treatment were identical. We included patients with full-thickness tears limited to the supraspinatus tendon and a type 2 acromion. We excluded patients with prior surgery, those with larger tears involving two or more tendons, those with a type 1 or 3 acromion, those with workers’ compensation claims, and those who had concomitant procedures (labral repair, acromioclavicular joint resection) There were 47 patients in group 1 and 46 in group 2. Minimum follow-up was 1 year (mean, 15.6 3.3 months). We recorded the American Shoulder and Elbow Surgeons (ASES) shoulder scores preoperatively and postoperatively. There was no statistical difference in postoperative ASES scores between group 1 (91.5 10.3) and group 2 (89.2 15.1) (P .392). The change in ASES score over time did not differ between the two groups (61.1 vs 60.2, P .363). In conclusion, within the parameters described above, arthroscopic subacromial decompression does not appear to change the functional outcome after arthroscopic repair of the rotator cuff.

Outcome Expectancies, Functional Outcomes, and Expectancy Fulfillment for Patients With Shoulder Problems

Wed, 04 Feb 2004 14:00:00 GMT

Methods: Patients (n 199) treated for shoulder problems at one orthopedic surgeon’s office completed a baseline survey comprised of measures of outcome expectancies, shoulder function, health status, and demographics. At 1 month, 2 months, and 3 months, patients completed a mailed follow-up survey comprised of all baseline measures except demographic variables. At 3 months, a measure of expectancy fulfillment was added. A general linear modeling approach was used to assess the significance and effect size of 1) outcome expectancies on changes in shoulder function; and (2) outcome expectancies, shoulder function changes, and their interaction on perceptions of expectancy fulfillment. Results: Outcome expectancies significantly predicted changes in shoulder function and accounted for 10% of the variance in functional improvement. The improvement difference between patients with high expectancies compared with those with low expectancies was clinically relevant (4.57 points), as it was greater than the minimal clinically important difference (3.02 points).

Shoulder Rotator Cuff Basic Science Kelly compared the muscle-firing patterns in both symptomatic and asymptomatic patients who had two-tendon rotator cuff tears. Asymptomatic patients demonstrated increased firing of the intact subscapularis, whereas symptomatic patients continued to rely on torn rotator cuff tendons and scapular muscle substitution, resulting in compromised function. Kalandiak compared the in vivo kinematics of painless shoulders that had massive rotator cuff tears with those of normal shoulders with use of cinefluoroscopy. Only one patient demonstrated normal ball and socket kinematics; most demonstrated increased scapulothoracic motion during initial forward elevation. The mean active forward elevation was 129° when performed against no resistance but only 86° when performed against resistance.

Shoulder Rotator Cuff Basic Science Several studies have employed sophisticated animal models to investigate rotator cuff repair and healing. Coleman reported on a chronic rotator cuff injury and repair model involving sheep. Infraspinatus contractile forces and histological findings were evaluated at various times following either immediate or delayed tendon repair. Longer delays to repair led to greater decreases in force and more modest recovery following repair. Muscle biopsies confirmed progressive fatty infiltration that was partially reversed after tendon repair in the group with a six-week delay before repair but not in the group with an eighteen-week delay before repair. This model has important implications regarding the recovery of strength following the repair of chronic rotator cuff tears. Rodeo presented a study on growth factor-enhanced rotator cuff tendon-bone healing in a sheep model. Histological analysis demonstrated greater new-bone and fibrovascular tissue...

A Randomized Controlled Trial Comparing 2 Instructional Approaches to Home Exercise Instruction Following Arthroscopic Full-Thickness Rotator Cuff Repair Surgery

Sat, 09 Nov 2002 22:00:00 GMT

Background: Advances in orthopedic surgery and rehabilitation have placed increased emphasis on home exercise programs. Therefore, assessing the effectiveness of different methods of home program instruction is important. Methods and Measures: Patients who consented to undergo surgical repair were randomly assigned to either a videotape or personal instruction group. A self-reported compliance log categorized subjects as fully compliant, partially compliant, or noncompliant. The Shoulder Pain and Disability Index and the University of Pennsylvania Shoulder Scale scores were obtained from subjects preoperatively and at 12, 24, and 52 weeks postoperatively. The null hypotheses that neither group would have better outcomes as measured by 2 shoulder outcome scales at any level of compliance over 4 levels of time, were assessed by 2 separate 2×3×4 multiple analyses of variances (MANOVAs), 1 for each outcome measure ( = 0.025). Results: Neither MANOVA was significant and the null hypotheses were not rejected. The main effect of time (number of weeks postsurgery) was significant across all time intervals for both outcome measures (P0.0005). Conclusions: With a therapist available for questions, patients who utilized the videotape method for their home program instruction had self-reported outcomes equal to patients instructed in their home program personally by a physical therapist. Self-reported compliance with the rehabilitation program had little effect on the outcomes. J Orthop Sports Phys Ther 2002;32:548–559... (download full pdf article)

Reliability by Surgical Status of Self-Reported Outcomes in Patients Who Have Shoulder Pathologies

Mon, 15 Jul 2002 14:00:00 GMT

Methods and Measures: A questionnaire containing self-report sections of 4 shoulder scales was administered to study participants twice with 1 week between administrations. The outcome measures examined were the: (1) University of California at Los Angeles (UCLA) Shoulder Score; (2) Constant-Murley Scale (CMS); (3) American Shoulder and Elbow Society (ASES) Shoulder Index; and (4) Shoulder Pain and Disability Index (SPADI). Intraclass correlation coefficients (ICC) were calculated to estimate the test-retest reliability of each of the scales and subscales. The interitem consistencies of the multi-item subscales were assessed using Cronbach’s alpha. The effect of surgical status on shoulder outcome scale reliability was evaluated using a general linear models approach. Results: The interitem consistency estimates for the multi-item scales were high with both operative and nonoperative participants (0.88 to 0.96). With the exception of the satisfaction subscale of the UCLA Shoulder Score for the nonsurgical group, the estimated intraclass coefficients ranged from 0.51 to 0.91. The prediction of UCLA-satisfaction and ASES-disability, pain, and total retest scores was improved with the addition of surgical status into a regression model... (download full pdf article)

Development and Psychometric Evaluation of the Flexilevel Scale of Shoulder Function

Sun, 20 Jan 2002 22:00:00 GMT

A more efficient approach is to use modern psychometric methods to construct an adaptive scale in which patients respond only to items that are targeted at their level of shoulder function. OBJECTIVES. We developed a Flexilevel Scale of Shoulder Function (FLEX-SF). This scale includes three testlets that target low, medium, and high shoulder function. Scores on the testlets were equated to a common mathematical metric. DESIGN AND SUBJECTS. We developed an initial pool of 68 items. This pool was administered to 400 patients, and responses were calibrated using a rating scale model. Subsets of items were identified for an easy, medium difficulty, and hard testlet. Properties of the scale were evaluated in a 3-month longitudinal study of 200 shoulder patients. RESULTS. The FLEX-SF exhibited high reliability at both the scale level (intraclass correlation coefficient [3,1] 0.90) and specific trait levels. The validity of the FLEX-SF was supported by its internal and external responsiveness (Guyatt responsiveness index 1.12) and the pattern of its associations with other health status measures. CONCLUSIONS. The FLEX-SF can be used as a primary endpoint in clinical trials even when there are relatively few people in each treatment group. The scale also has excellent properties for use in clinical settings tracking individual changes over time.... (download full pdf article)

Shoulder Rotator Cuff Basic Science Uhthoff presented evidence that, in a rabbit model, the fatty infiltration that occurs in muscle after a rotator cuff tear is not reversed by a successful rotator cuff repair. This observation may prompt surgeons to reconsider rotator cuff repair for patients with this finding on magnetic resonance imaging. Altchek reported that a subscapularis tear increases external rotation and posterior translation and that this effect is not increased by the addition of an anterior capsular tear. Impingement: The debate continues regarding the role of acromioplasty during the operative treatment of rotator cuff tears or impingement. Nirschl and Matsen advocated avoiding acromioplasty because of potential destabilization of the glenohumeral joint, harm to the deltoid origin, loss of the acromial lever, postoperative hemorrhage and adhesion, increased postoperative pain, and occasional acromial fracture. Partial-Thickness: Tears Warren found that arthroscopic...

The Measurement Level and Trait-Specific Reliability of 4 Scales of Shoulder Functioning: An Empiric Investigation

Fri, 23 Nov 2001 23:00:00 GMT

Setting: Office of private practice orthopedic surgeon with practice limited to the shoulder. Participants: One-hundred ninety-two shoulder patients. Interventions: Participants completed the American Shoulder and Elbow Surgeons Patient Self-Evaluation Form (function subscale, modified), the disability subscale of the Shoulder Pain and Disability Index, the Simple Shoulder Test, and the function subscale of the University of Pennsylvania Shoulder Scale. Main Outcome Measures: The patients’ responses were calibrated by using a partial credit model. We calculated standard errors of measurement and plotted the 95% confidence interval for different levels of shoulder functioning. We compared scales’ raw scores with their equal interval measures obtained in the Rasch calibration. Results: The scales did not measure all levels of shoulder functioning with equal precision, suggesting that commonly used reliability estimates misrepresent scale precision in certain subpopulations. Conclusions: The scales’ raw scores were found to be not of equal interval, calling into question the scoring systems recommended by the developers of these scales and the use of the scores in some statistical procedures.

Arthroscopic Treatment of Multidirectional Glenohumeral Instability: 2- to 5-Year Follow-up

Fri, 02 Mar 2001 23:00:00 GMT

The average age at the time of operation was 30 years (range, 15 to 56 years). The average interval from operation to final evaluation was 35 months (range 26 to 67 months). The American Shoulder and Elbow Surgeons (ASES) Shoulder Index, Constant, Rowe, and UCLA scores were recorded preoperatively and at final evaluation. Results: Preoperatively, no patients were rated overall as good to excellent according to the Rowe scale; at final follow-up 94% (44 of 47 patients) were rated as good to excellent. One patient was considered a failure of the index operation due to persistent instability and underwent a second operative procedure. One patient noted a loss of strength during sports, and 2 patients had pain that limited their throwing ability. The ASES Shoulder Index improved to 94.7 from 45.4 (P 5 .001). The absolute Constant score improved to 91.7 from 60 (P 5 .001). The Rowe score improved to 93.7 from 14.2 (P 5 .001). The UCLA total score improved to 33.1 from 17.4 (P 5 .001). Average passive external rotation at 90° abduction measured 88.2°. Twenty-two of 26 patients (85%) returned to their desired levels of sports following the operations. Conclusions: Patients with multidirectional glenohumeral instability have multiple lesions within the shoulder and the surgeon must individualize the operative treatment.

Arthroscopic treatment of bidirectional glenohumeral instability: Two- to five-year follow-up

Mon, 29 Jan 2001 22:15:00 GMT

The American Shoulder and Elbow Surgeons’ Shoulder Index and the Constant, Rowe, and University of California at Los Angeles scores were recorded preoperatively and at final evaluation. Preoperatively, no patients rated good to excellent overall (according to the Rowe Scale), whereas at final follow-up 91% (49 of 54 patients) rated good to excellent. The American Shoulder and Elbow Surgeons’ Shoulder Index improved to 94 from 45.5 (P = .001). The absolute Constant score improved to 92 from 57 (P = .001). The Rowe score improved to 92 from 20.3 (P = .001). The University of California at Los Angeles total score improved to 32.7 from 18.6 (P = .001). Average passive external rotation at 90 degrees of abduction measured 89.5 degrees. Forty patients returned to sports, but 10 (25%) of these patients participated at a lower level. For each of 4 patients, the index operation was considered a failure because of persistent instability; 1 patient underwent a second operative procedure. Thermal capsulorraphy (with a Holmium laser) of the glenohumeral ligaments was used to supplement suture repair, but in no shoulder was thermal capsulorraphy used as the only treatment. The etiology of bidirectional glenohumeral instability is complex, and operative correction of multiple intraarticular lesions was necessary. (J Shoulder Elbow Surg 2001;10:28-36.)...

Arthroplasty Developments in the Design of Prosthetic Shoulder Arthroplasty Humerus Recent developments in the design of humeral head replacements have focused on enhancing the ability of the prosthesis to replicate normal anatomic relationships. These third-generation modular designs provide both variable neckshaft angles and multiple head offsets in three dimensions. M.L. Pearl performed a three-dimensional analysis in cadavers and demonstrated that the variable geometry of the third-generation prosthetic system allowed for significantly better replication of the three-dimensional position of the center of rotation and the articulation point with preservation of the articular surface arc compared with the secondgeneration prosthetic systems. The most troublesome feature of the second-generation modular systems was the gap that was created by the prosthetic collar and the Morse taper between the prosthetic head and the humeral osteotomy site. Some newer designs have eliminated this gap. J.J.P. Warner compared hemiarthroplasty with use of a second-generation design with hemiarthroplasty with use of a third-generation design. The head-to-tuberosity height was greater than that on the contralateral, normal side in patients who underwent hemiarthroplasty with a second-generation prosthesis. Moreover, these shoulders had a decreased radius of curvature of the articular surface and an increased lateral offset compared with these parameters in the uninvolved shoulder. In contrast, all radiographic parameters were reconstructed to 2 mm of normal or less in the patients who underwent hemiarthroplasty with a more adaptable design. Although these studies raise concerns about the long-term survival of the prosthesis, currently there is no evidence from any study that third-generation implants produce superior clinical outcomes, to our knowledge. In fact, R.J. Friedman found no correlation between various radiographic measurements and the functional score following total shoulder arthroplasty. He concluded that good surgical technique, including careful soft-tissue balancing, appears to compensate for changes in the anatomic relationships.

Comparison of the University of California–Los Angeles Shoulder Scale and the Simple Shoulder Test With the Shoulder Pain and Disability Index: Single-Administration Reliability and Validity

Sat, 05 Aug 2000 21:00:00 GMT

Methods. Cronbach alpha values and standard errors of measurement (SEM) were calculated for each of the multi-item subscales. Validity was examined through calculation of correlation coefficients among the 3 scales. Factor analysis was completed to assess the underlying constructs of the SPADI and the SST. Results. Cronbach alpha values ranged from .85 to .95. The SEM values for the multi-item scales ranged from 4.75 to 11.65. Evidence for validity to reflect function was indicated by the correlation between the SST and the SPADI disability subscale. The factor analysis of the SPADI revealed loading on 1 factor, whereas the SST loaded on 2 factors. Conclusion and Discussion. All scales demonstrated good internal consistency, suggesting that all items for each scale measure the same construct. However, the SEMs for all scales were high. Factor loading was inconsistent, suggesting that patients may not distinguish between pain and function. [Roddey TS, Olson SL, Cook KF, et al.

There were forty-four male and nine female patients. The mean interval from the time of the operation to the final follow-up evaluation was thirty-three months (range, twenty-six to sixty-three months). The scores on the American Shoulder and Elbow Surgeons (ASES) Shoulder Index and the rating systems of Constant and Murley, Rowe et al., and the University of California at Los Angeles (UCLA) were recorded preoperatively and at the time of the final follow-up.

Arthroscopic Treatment of Acute Traumatic Anterior Glenohumeral Dislocation and Greater Tuberosity Fracture

Fri, 17 Sep 1999 21:00:00 GMT

CASE REPORT A 46-year-old right-hand dominant man was involved in a polo accident and sustained an anteriorinferior glenohumeral dislocation along with a greater tuberosity fracture (Fig 1). The dislocation was reduced in the emergency room but, because of the displacement of the greater tuberosity fracture, the treating orthopaedist referred the patient to our office. His medical history included no prior significant shoulder problems. Physical examination was limited by pain from the shoulder injury but it revealed normal neurovascular status. Plain radiographs showed prereduction and postreduction views of the dislocation and displaced greater tuberosity fracture (Fig 2). The patient wished to pursue his avocation of competitive polo, so we advised operative treatment. SURGICAL TECHNIQUE After the successful induction of general anesthesia with interscalene block supplementation, we placed the patient in the sitting position and prepared and draped the arm. An incision was made 1 cm inferior and 1 cm medial to the posterolateral corner of the acromion and the blunt trocar and cannula were inserted into the glenohumeral joint. A Bankart lesion was seen with detachment of the labrum-ligament complex from 1 to 4 o’clock. The anterior scapular neck and glenoid rim were abraded and two suture anchors inserted. The labrum-ligament complex was reattached anatomically. The arthroscope was removed and attention turned to the subacromial space. The trocar and cannula were inserted into the subacromial space and the lateral portal site was identified with a spinal needle. A large self-sealing cannula and trocar were inserted, followed by an arthroscopic probe. The... (download full pdf article)

Eleven tears were small (less than one centimeter in length), forty-five were medium (one to three centimeters), eleven were large (more than three to five centimeters), and six were massive (more than five centimeters). The average length of the tear was twelve millimeters, and the average width was twenty-seven millimeters. Sixty-nine tendons were repaired anatomically, and four were repaired an average of three millimeters (range, two to eight millimeters) medial to the anatomical insertion of the tendon. An average of 2.3 (range, one to four) suture anchors were used in the repair. Sixty-three glenohumeral joints were normal, and ten had an intra-articular lesion. Seven patients had a concomitant resection of the acromioclavicular joint. The average duration of the operation was fiftysix minutes (range, thirty-five to ninety minutes).

Early Effectiveness of Arthroscopic Repair for Full-Thickness Tears of the Rotator Cuff

Fri, 02 Jan 1998 22:00:00 GMT

The Short Form- 36 (SF-36) General Health Survey revealed significant improvements in the most recent follow-up scores compared with the preoperative scores with regard to physical functioning (p = 0.0001), role-physical (p = 0.0001), bodily pain (p = 0.0001), vitality (p = 0.0001), social functioning (p = 0.0001), role-emotional (p = 0.006), mental health (p = 0.0213), and physical component summary (p = 0.0001).

Most importantly, all three shoulder- rating systems demonstrated significant improvements in the postoperative scores for pain and function (p = 0.0001). While a general health status instrument such as the SF-36 can document the impact of an orthopaedic condition on a patient as well as the results of treatment, a more complete representation of the patient’s condition requires the use of region-specific self-assessment questionnaires and evaluation by a physician.
