Shoulder rotational strength, movement, pain and joint tenderness as indicators of upper-extremity activity limitation in moderate rheumatoid arthritis.

In this study 32 women were investigated in order to elucidate how shoulder rotational muscular strength and upper-extremity impairments are associated with activity limitation in moderate rheumatoid arthritis. A regression analysis was carried out to determine whether these variables could indicate the outcomes of a shoulder-arm disability questionnaire (SDQ) comprising three parts, plus parts of the Health Assessment Questionnaire, the Functional Status Questionnaire and the Sickness Impact Profile. Shoulder-arm and wrist movements were moderate-to-good (r = 0.53, p < 0.01 and r = 0.58, p < 0.01, respectively) in relation to isometric internal rotational strength. The relationship between isokinetic concentric and eccentric internal rotational strength was moderate-to-good (r = 0.59, p < 0.01). Isokinetic eccentric internal rotation strength, shoulder-arm movement, joint tenderness and pain variables together indicated 25-61% (adjusted R2) of the variation in SDQ. Eccentric strength had the highest adjusted R2 (41%) in relation to SDQ 1, covering mainly personal hygiene. Shoulder rotational strength did not indicate the more general instruments. Thus, hand and elbow impairments also are probably important in explaining activity limitations.

The effect of physiotherapy on shoulder function in patients surgically treated for breast cancer: a randomized study.

The effect of physiotherapy on shoulder function in patients surgically treated for breast cancer was examined through a randomized controlled trial. One hundred and thirty-nine patients with newly diagnosed breast cancer were enrolled in the study. Sixty-two (45%) had Breast Conserving Therapy and 77 (55%) had Modified Radical Mastectomy (Axillary dissection of level I and II was included in both procedures). Enrolled patients were randomized to either group A or group B. Group A was offered, team instructed physiotherapy consisting of 12 sessions of 60 min, two sessions a week. The treatment was instituted between the sixth and eight postoperative week. Group B was also offered team instructed physiotherapy, consisting of 12 sessions of 60 minute two sessions a week, but not until the 26th postoperative week. The patients were seen for follow-up examinations four times during the first postoperative year (after 7, 13, 26 and 56 weeks). Shoulder function was assessed by the Constant Shoulder Score preoperatively and at the four follow-up examinations. Team instructed physiotherapy was found to improve the shoulder function significantly in patients treated surgically for breast cancer. The effect of the treatment was influenced by the type of surgery performed, and in mastectomised patients, also by the application of radiation therapy. Compromised shoulder function is a less frequent and less severe side effect to breast conserving therapy as compared to modified radical mastectomy.

Performance changes for patients with chronic obstructive pulmonary disease on long-term oxygen therapy after physiotherapy.

OBJECTIVE: To investigate whether patients with chronic obstructive pulmonary disease on long-term oxygen therapy would benefit from an early 8-week rehabilitation programme in terms of exercise performance, health-related quality of life and activities of daily living. METHODS: Two weeks after onset of oxygen therapy, 20 patients were randomized to rehabilitation (group A) or not (group B). Exercise performance was measured using a 6-minute walking test. Health-related quality of life was measured with the Chronic Respiratory Disease Questionnaire. Activity of daily living ability was measured with the Stanford Health Assessment Questionnaire. RESULTS: The mean 6-minute walking distance increased by 35% (p < 0.01) in group A after rehabilitation. The mean increase in group B was only 8% (n.s.). Patients in group A reported less overall dyspnoea after rehabilitation (p < 0.05) and, compared with group B, reported better activity of daily living ability (p < 0.01). CONCLUSION: Patients with chronic obstructive pulmonary disease on long-term oxygen treatment may improve their walking distance, experience less dyspnoea and improve activity of daily living ability with an early rehabilitation programme.

Muscles may contribute to shoulder dislocation and stability.

Joint instability is one of the most common human afflictions, affecting not only the hip, knee, and shoulder but all joints of the body. Surgical repair for joint instability is done commonly, yet has not been able to restore function consistently. Pain, recurrence of instability, joint stiffness, muscle injury, and degenerative joint disease are all too common sequelae. Because the glenohumeral joint is most commonly dislocated, efforts have been directed to understanding shoulder instability. Study has included not only the static restraints (capsulolabrum, articular surfaces, intracapsular pressure), but also their important interplay with the dynamic restraints (shoulder muscles). Furthermore, not only were muscles known to stabilize the joint studied but also may have contributed to dislocation. An in vitro, cadaveric model that included relevant shoulder muscles and a mechanism of dislocation similar to an in vivo mechanism was developed. The capsulolabral pathoanatomy that occurred after dislocation was studied. Increased understanding of joint dislocation may improve functional results after rehabilitation and surgical repair, not only at the shoulder, but also at all other joints.

Recentering the humeral head for glenoid deficiency in total shoulder arthroplasty.

Substantial posterior glenoid wear causing static posterior subluxation of the humeral head in patients with primary osteoarthritis has been described. Persistent humeral head subluxation after total shoulder arthroplasty can result in early polyethylene wear and glenoid component loosening. In our prospective cohort study, we hypothesized that in patients with posterior glenoid wear from osteoarthritis, static posterior decentering of the humeral head could be recentered during total shoulder arthroplasty by surgical correction of glenoid alignment in the transverse plane with soft tissue balancing. We performed total shoulder arthroplasties in 77 patients with primary osteoarthritis and a mean age of 67.6 years. The mean clinical and radiographic followup was 2 years (range, 1-7 years). Patients with preoperative posteriorly decentered humeral heads did not have posterior decentering develop postoperatively. Twenty patients (83.3%) had centered humeral heads and four patients (16.6%) had anterior decentering. Midterm results of total shoulder arthroplasties in shoulders with humeral head decentering caused by glenoid deficiency in the transverse plane showed correction of the decentering by lowering the high side or by bone grafting with soft tissue balancing can be well maintained.

Shoulder hemiarthroplasty to manage haemophilic arthropathy: two case studies.

Bleeds within the shoulder joint can lead to significant joint destruction and may have associated pain, decreased range of movement (ROM), and impaired function. Conservative management should involve prompt administration of Factor VIII and physiotherapy to address all surrounding structures so as to minimize further damage. If conservative management fails to relieve severe, unremitting shoulder pain in the presence of underlying arthropathy, then arthroplasty may be considered. Outcomes of arthroplasties performed for osteoarthritis and rheumatoid arthritis appear favourable. Few articles, however, have addressed shoulder arthroplasty to manage haemophilic arthropathy, and no reports have documented the rehabilitation process. Three hemiarthroplasties were performed at the Royal Brisbane and Women's Hospital on two men with haemophilia. There were no surgical or postoperative complications. Rehabilitation included intensive physiotherapy. The results in each case revealed a decrease in pain, and an increase in ROM and function postoperatively. These findings suggest that hemiarthroplasty with postoperative physiotherapy may be a feasible option to manage severe, chronic and progressing shoulder pain as a result of haemophilic arthropathy of the shoulder.

Arthrographic joint distension with saline and steroid improves function and reduces pain in patients with painful stiff shoulder: results of a randomised, double blind, placebo controlled trial.

OBJECTIVE: To determine whether arthrographic distension with a mixture of saline and steroid, in patients with painful stiff shoulder for at least 3 months, is better than placebo in improving function, pain, and range of motion at 3, 6, and 12 weeks. METHODS: A randomised, placebo controlled trial with participant and outcome assessor blinding in which shoulder joint distension with normal saline and corticosteroid was compared with placebo (arthrogram). Outcome measures, assessed at 3, 6, and 12 weeks, included a shoulder-specific disability measure (SPADI), a patient preference measure (Problem Elicitation Technique (PET)), pain, and range of active motion. RESULTS: From 96 potential participants, 48 were recruited. Four withdrew from the placebo group after the 3 week assessment and three subsequently received arthrographic distension with saline and steroid. At 3 weeks, significantly greater improvement in SPADI (p = 0.005), PET, overall pain, active total shoulder abduction, and hand behind back was found in participants in the joint distension and steroid group than in the placebo group. At 6 weeks the results of the intention to treat analysis favoured joint distension, although the between-group differences were only significant for improvement in PET (difference in mean change in PET between groups = 45.9 (95% CI 3.2 to 88.7). Excluding the four withdrawals, the between-group differences for the disability and pain measures significantly favoured distension over placebo. At 12 weeks, both the intention to treat analysis and an analysis excluding the four withdrawals demonstrated a significantly greater improvement in PET score for the distension group. CONCLUSIONS: Short term efficacy of arthrographic distension with normal saline and corticosteroid over placebo was demonstrated in patients with painful stiff shoulder.

Is tennis a predisposing factor for degenerative shoulder disease? A controlled study in former elite players.

BACKGROUND: High demands imposed to the shoulder during tennis activity can decrease the efficiency of static and dynamic constraints. Subtle or frank instability of the glenohumeral joint may occur, and long term degenerative changes may be expected. OBJECTIVE: To determine and compare the prevalence of primary glenohumeral osteoarthritis in senior tennis players and matched controls. STUDY DESIGN: Cross sectional controlled study. METHODS: 18 asymptomatic senior tennis players were studied (17 male; mean (SD) age, 57.2 (8.8) years) with no history of shoulder surgery or major trauma. There were 18 matched controls. Radiographs were used to determine glenohumeral osteoarthritic changes: joint space narrowing, humeral and glenoid subchondral sclerosis, humeral and glenoid juxta-articular cysts, osteophytes, humeral and glenoid flattening, humeral posterior displacement and glenoid posterior erosion. Findings were classified as normal, minimal, moderate, or severe changes. RESULTS: 33% of the players (95% confidence interval (CI), 13% to 59%) had osteoarthritic changes in their dominant shoulder (n = 6; five with minimal changes, one with moderate changes), and 11% of the controls (95% CI, 1% to 34%) had articular degeneration on their dominant side (n = 2; both minimal changes) (p = 0.04, Wilcoxon test). The osteoarthritic group was significantly older than the players without degenerative changes (p = 0.008). CONCLUSIONS: The prevalence of glenohumeral osteoarthritis in the dominant shoulder was greater in former elite tennis players than in sedentary controls. Prolonged intensive tennis practice may be a predisposing factor for the development of mild degenerative articular changes in the dominant shoulder.

The "bench-presser's shoulder": an overuse insertional tendinopathy of the pectoralis minor muscle.

BACKGROUND: Tendinopathies of the rotator cuff muscles, biceps tendon and pectoralis major muscle are common causes of shoulder pain in athletes. Overuse insertional tendinopathy of pectoralis minor is a previously undescribed cause of shoulder pain in weightlifters/sportsmen. OBJECTIVES: To describe the clinical features, diagnostic tests and results of an overuse insertional tendinopathy of the pectoralis minor muscle. To also present a new technique of ultrasonographic evaluation and injection of the pectoralis minor muscle/tendon based on use of standard anatomical landmarks (subscapularis, coracoid process and axillary artery) as stepwise reference points for ultrasonographic orientation. METHODS: Between 2005 and 2006, seven sportsmen presenting with this condition were diagnosed and treated at the Cape Shoulder Institute, Cape Town, South Africa. RESULTS: In five patients, the initiating and aggravating factor was performance of the bench-press exercise (hence the term "bench-presser's shoulder"). Medial juxta-coracoid tenderness, a painful active-contraction test and bench-press manoeuvre, and decrease in pain after ultrasound-guided injection of a local anaesthetic agent into the enthesis, in the absence of any other clinically/radiologically apparent pathology, were diagnostic of pectoralis minor insertional tendinopathy. All seven patients were successfully treated with a single ultrasound-guided injection of a corticosteroid into the enthesis of pectoralis minor followed by a period of rest and stretching exercises. CONCLUSIONS: This study describes the clinical features and management of pectoralis minor insertional tendinopathy, secondary to the bench-press type of weightlifting. A new pain site-based classification of shoulder pathology in weightlifters is suggested.

Randomised controlled trial of single, subacromial injection of methylprednisolone in patients with persistent, post-traumatic impingment of the shoulder.

OBJECTIVE: To evaluate the impact on recovery, of single subacromial injection of methylprednisolone in patients with persistent, post-traumatic impingement of the shoulder. DESIGN: Randomised, controlled study. SETTING: Large accident and emergency department in Leicester, UK. PARTICIPANTS: 98 patients with persistent, post-traumatic impingement of the shoulder. INTERVENTION: Single subacromial injection of methylprednisolone with bupivicaine (group S, n=54) or bupivicaine only (group C, n=44). MAIN OUTCOME MEASURES: Pain using a 10 cm visual analogue scale (VAS) and active shoulder abduction. RESULTS: Comparison of pain scores by the 10 cm VAS between group and group C showed no statistical difference at 3, 6, or 12 weeks. Mean patient pain scores at 12 weeks were 1.38 in both groups (p=0.99). There were 16 patients in group S (mean age 52 years) with a 10 cm VAS greater than 1 (95% CI CI 0.17 to 0.43), compared with 13 patients (mean age 57 years) in group C (95% CI 0.17 to 0.45). Comparison of active shoulder abduction between group S and group C showed no statistical difference at 3, 6, or 12 weeks. Mean active abduction at 12 weeks was 168.9 degrees in group S and 170.3 degrees in group C (p=0.8). There were 10 patients in group S (mean age 60.5) with active abduction less than 170 at 12 weeks (95% CI 0.09 to 0.31), compared with five patients (mean age 62 years) in group C (95% CI 0.04 to 0.24). CONCLUSIONS: Single subacromial injection of methylprednisolone has no beneficial impact on reducing the pain, or the duration of immobility in patients with persistent post-traumatic impingement of the shoulder

Clinical significance of the V-shaped space in the subluxed shoulder of hemiplegics.

Recently, it has been proposed that shoulder subluxation in hemiplegia is accompanied by 1) the appearance of a V-shaped articular configuration occurring between the humeral head and glenoid fossa and 2) the presence of chronic pain. The main purpose of this study was to investigate the validity of these statements. We evaluated 40 hemiplegic subjects over 3 months. Radiographs of the affected and nonaffected shoulders were taken at both a frontal plane (0 degree) and a 45 degree incidence. From these patients, subluxed (n = 19) and nonsubluxed (n = 21) groups were formed. Pain was evaluated using the Present Pain Intensity index of the McGill Pain Questionnaire. On these x-ray films, measurements were taken of the V-shaped space, abduction of the arm, and rotation of the scapula. The statistical analysis (analysis of variance for repeated measures) contrasted the results obtained from the nonaffected side with those from the affected side over the 3 months studied. At the 45 degree angle, which better exposes the articular configuration of the shoulder, the difference in the V angle between the affected and nonaffected shoulders was significant for the subluxed group (p less than 0.01), indicating that such a V-shaped space can be identified. The measures taken also indicate that a downward subluxation of the humeral head occurs relative to the scapula without any systematic abduction of the humerus or downward rotation of the scapula. None of the results obtained from the frontal plane x-ray films was significant. Finally, no significant relation was found between subluxation and shoulder pain.

Quantification of posterior capsule tightness and motion loss in patients with shoulder impingement.

The relationship between posterior capsule tightness and dysfunction has long been recognized clinically but has not been biometrically quantified. The purpose of this study was to quantify changes in range of motion and posterior capsule tightness in patients with dominant or nondominant shoulder impingement. Measurements of posterior capsule tightness and external and internal rotation range of motion were made in 31 patients with shoulder impingement and in 33 controls without shoulder abnormality. Patients with impingement in the nondominant arm had increased posterior capsule tightness and decreased internal and external rotation range of motion compared with controls. Patients with impingement in their dominant arm had increased posterior capsule tightness and reduced internal rotation range of motion but no significant loss of external rotation range of motion compared with controls. Posterior capsule tightness in impingement patients showed a significant correlation with loss of internal rotation range of motion. Patients with shoulder impingement in their nondominant arm had a more global loss of range of motion compared with patients having impingement in their dominant arm. We believe we have described a valid clinical measurement for identifying posterior capsule tightness in patients with shoulder impingement.

Effect of pitch type, pitch count, and pitching mechanics on risk of elbow and shoulder pain in youth baseball pitchers.

BACKGROUND: Joint pain is thought to be an early sign of injury to a pitcher. OBJECTIVE: To evaluate the association between pitch counts, pitch types, and pitching mechanics and shoulder and elbow pain in young pitchers. STUDY DESIGN: Prospective cohort study. METHODS: Four hundred and seventy-six young (ages 9 to 14 years) baseball pitchers were followed for one season. Data were collected from pre- and postseason questionnaires, injury and performance interviews after each game, pitch count logs, and video analysis of pitching mechanics. Generalized estimating equations and logistic regression analysis were used. RESULTS: Half of the subjects experienced elbow or shoulder pain during the season. The curveball was associated with a 52% increased risk of shoulder pain and the slider was associated with an 86% increased risk of elbow pain. There was a significant association between the number of pitches thrown in a game and during the season and the rate of elbow pain and shoulder pain. CONCLUSIONS: Pitchers in this age group should be cautioned about throwing breaking pitches (curveballs and sliders) because of the increased risk of elbow and shoulder pain. Limitations on pitches thrown in a game and in a season can also reduce the risk of pain. Further evaluation of pain and pitching mechanics is necessary.

The unstable shoulder in the adolescent athlete.

Shoulder dislocation and subluxation occur frequently in athletes, with peaks in the second and sixth decades. The majority of traumatic dislocations are in the anterior direction. The most frequent complication of shoulder dislocation is recurrence--a complication that occurs much more often in the adolescent population. The dynamic (muscular) and static (predominantly capsuloligamentous and labral) restraints to shoulder instability are now well defined. Recent surgical procedures for shoulder instability have become less interventional and have focused on restoring disrupted static restraints. The aim of rehabilitation is to enhance the dynamic muscular and proprioceptive restraints to shoulder instability.

Posterior instability of the shoulder with secondary impingement in elite golfers.

BACKGROUND: Shoulder injuries in golf are related to the biomechanics of the golf swing and typically occur in the lead arm at the top of the back swing. PURPOSE: We report a newly recognized entity in a series of elite golfers: posterior glenohumeral instability associated with subacromial impingement. STUDY DESIGN: Retrospective review. METHODS: Eight elite golfers were treated between March 1991 and July 1998 for pain occurring in the nondominant, lead shoulder at the top of the back swing. Posterior instability was diagnosed in all eight patients; six of the eight also demonstrated signs of subacromial impingement. Initial treatment consisted of rehabilitation. For patients in whom rehabilitation failed, surgery was performed. RESULTS: Two patients improved with nonoperative treatment and returned to play immediately. Six patients underwent shoulder arthroscopy with posterior thermal capsulorrhaphy. Four of the six also underwent arthroscopic subacromial decompression. The six surgically treated patients returned to play at an average 4 months after surgery. At an average 4.5 years of follow-up, all eight patients were playing at their previous level of competitive play. One patient had complications that led to the need for subsequent arthroscopic subacromial decompression; she eventually returned to competitive play. CONCLUSION: Clinicians should be aware of posterior shoulder instability and the associated secondary diagnosis of rotator cuff impingement as a possible cause of shoulder pain in elite golfers.

The role of the long head of the biceps muscle and superior glenoid labrum in anterior stability of the shoulder.

The authors conducted a study to determine if the long head of the biceps muscle and its attachment at the superior glenoid labrum play a role in stability of the shoulder in an overhead position. Their study used a dynamic cadaveric shoulder model that simulated the forces of the rotator cuff and long head of biceps muscles as the glenohumeral joint was abducted and externally rotated. Their data suggest that the long head of the biceps muscle contributes to anterior stability of the glenohumeral joint by increasing the shoulder's resistance to torsional forces in the vulnerable abducted and externally rotated position. The biceps muscle also helps to diminish the stress placed on the inferior glenohumeral ligament. Detachment of the superior glenoid labrum is detrimental to anterior shoulder stability as it decreases the shoulder's resistance to torsion and places a greater magnitude of strain on the inferior glenohumeral ligament.

Glenoid rim lesions associated with recurrent anterior dislocation of the shoulder.

Twenty-five shoulders with recurrent instability and associated anterior glenoid rim lesions were reviewed to 1) develop a classification system of the lesions, 2) evaluate radiographic techniques in detecting the lesions, and 3) analyze the outcome of surgery. Lesions were classified into three types: Type I, a displaced avulsion fracture with attached capsule; Type II, a medially displaced fragment malunited to the glenoid rim; and Type III, erosion of the glenoid rim with less than 25% (Type IIIA) or greater than 25% (Type IIIB) deficiency. Lesions were detected by plain radiographs (19 shoulders) or supplemental CT-arthrograms (12 shoulders) or both. In 16 Type I fractures, both the bony fragment and capsule were reattached to the glenoid rim. In five Type II and three Type IIIA lesions, only the capsule was repaired to the remaining glenoid rim. In the one Type IIIB lesion, a coracoid transfer was performed. At an average followup of 30 months, 22 shoulders (88%) had satisfactory results without recurrent instability, whereas three shoulders (12%) had postoperative redislocations. The majority of recurrent anterior dislocations with associated glenoid rim lesions can be treated by suturing the fracture fragment or capsule or both to the glenoid rim and addressing associated capsular laxity.

Age-related changes in normal isometric shoulder strength.

Normative data are useful for assessing isometric shoulder strength in patients with bilateral shoulder abnormalities. The purpose of this study was to develop a normative database for shoulder strength in the clinically relevant positions and movements. Twenty combinations of exertions and postures-including flexion, extension, abduction, adduction, internal rotation, and external rotation-were tested for both the dominant and nondominant sides. Strength was measured isometrically using a modified Cybex II dynamometer. The cross-sectional study design included 120 subjects (60 women and 60 men) ranging in age from 20 to 78 years from southern Minnesota. Tables of normative strength data were constructed. Multivariate analyses were performed to assess the effect of age, sex, and weight on strength. Age was negatively associated with all strength measures, and weight was positively associated with them. Men were stronger than women when controlling for age and weight. Statistically significant differences between dominant and nondominant shoulders were found for only some of the strength measures taken. These normal data will be useful to the clinician, as they permit a standard against which to compare shoulder strength.
