Shoulder synovectomy.

The technique and results of synovectomy of the shoulder joint in rheumatoid arthritis with a mean follow up time of 5.3 years (1-16 years) is described. The original method included resection of acromion after loosening of the deltoid muscle and splitting of the rotator cuff. Since 1981 the simpler approach of Neer without resection of acromion has been used (for synovectomy as well as for prosthetic replacement) with an easier postoperative management and equally good results. Only in 6 of 54 shoulders a total replacement prosthesis has been inserted later, an indication of the lasting good effect of synovectomy, even in advanced cases where an additional debridement was necessary. The best results are obtained in early cases. Radiographic changes are late, indications should be based more on clinical findings. Access to good training facilities is mandatory.

[Transfer of trapezius muscle for reconstruction of abduction of the shoulder].

INTRODUCTION: After brachial plexus injuries, shoulder function is frequently impaired or lost. For reconstruction of the most important functions muscle transfers are indicated. To restore abduction and external rotation of the shoulder the trapezius muscle transfer is mainly used. PATIENTS AND METHODS: We demonstrate 16 patients with insufficient abduction of the shoulder joint. All patients were treated with the transfer of trapezius muscle (pars horizontalis). We used a modification of the technique of Saha. After the operation, the arm was immobilized in 80 degrees abduction for 6 weeks followed by 10 degrees adduction of the shoulder per week. Afterwards physiotherapy was started. Evaluation was done by the DASH score and Gilbert score. RESULTS: In all cases, an improvement of shoulder mobility was seen, assessed clinically and individually by the patient. The average DASH score was 37.4. For ten patients the results of the operation were very good, good, or satisfactory. Active abduction increased from 15 degrees (0-30 degrees) to 54 degrees (35-80 degrees) postoperatively. The external rotation was 9 degrees (-20-40 degrees) preoperatively and 19 degrees (0-70 degrees ) postoperatively. DISCUSSION: Trapezius muscle transfer for reconstruction of abduction is an easy and practicable method without serious complications. We achieved good stability and functionality of the shoulder. Intensive pre- and postoperative physiotherapy may provide greater improvement of mobility.

[Secondary impingement syndrome in athletes].

Dysfunction of the shoulder joint is based not only on anatomic conditions. The consideration of the special kinesiology of the shoulder helps to understand the shoulder pathology. This mainly applies to young "overhead athletes" like swimmers, handball-, basketball-, volleyball-, and racketplayers. These disciplines cause stress on the anterior joint structures (capsule, ligaments, labrum, subscapularis tendon) and lead to anterior instability. This includes anterior subluxation or even dislocation. Finally, an impingement syndrome with the typical symptoms can frequently result from these conditions. The impingement-syndrome of the elderly must be considered as a primary disease, whereas the young overhead athlete suffers from the impingement syndrome as a secondary disease and does not take the first place in therapy. The first step in therapy should to be treat the muscular imbalance of the shoulder. To gain a regular pattern of motion the rotator cuff must be strengthened. This regimen is likely to be successful in 80-90% of the cases. If the conservative therapy fails the surgical treatment may come into consideration. Arthroscopic surgery has the advantage not to affect the proprioceptivity. To retain the previous level of performance an adequate rehabilitation programme is essential for the athlete.

Osteoarthrosis following the Putti-Platt operation.

The objective of this study was to search for any degenerative changes in the shoulder joint following the Putti-Platt operation in a long-term follow up study, as most papers regarding that operation report a redislocation rate and a limitation of external rotation, but only a few mention osteoarthrosis (OA). Patients operated on between 1945 and 1971 answered a questionnaire and were invited for a clinical examination including standard X-rays of the shoulder. These films were compared with those taken preoperatively. OA was classified according to the Samilson and Prieto grading. Twenty-six patients could be re-examined on average 26 years after the operation. Fifteen had evident radiological signs of OA. According to Samilson and Prieto there were 11 mild, 2 moderate and 2 severe cases of OA. Nine patients had a Hill-Sachs defect and 3, a Bankart lesion. Patients over the age of 25 years at the time of the first dislocation developed OA more often. Following the Putti-Platt operation one has to expect radiological signs of OA in a long-term follow-up. Mainly minor forms are seen. Older patient age at the time of the first dislocation is a predisposing factor for the development of OA.

[Role of radiology in the diagnosis of joint chondrocalcinosis. The so-called atypical symptomatic aspects].

In a preceding article, we described "pseudogout" which is the expression of an episode of acute synovitis related to microcrystals of dehydrated calcium pyrophosphate invading the joint. This brutal episode of inflammation, predominantly occurring in the knee joint, is the most spectacular, most frequent and most characteristic manifestation of articular chondrocalcinosis. We attempted to demonstrate the important role of radiographs in the diagnosis, discovering in many cases the microcrystal impregnation of cartilage and fibrocartilage. But articular chondrocalcinosis, as has been shown by a large number of clinical and radiological surveys, may present a wide range of atypical or misleading forms, much different from the classic pseudogout. Among the different clinical presentations, some have no particularly special radiographic expression, showing only the common chondrocalcinosis lesions seen during the acute episodes of microcrystal related synovitis. This is the case in different situations of inflammation, notably subacute arthritis, purely algic forms and exsudative forms (chronic hydarthrosis, haemarthrosis). Complete clinical latency is also observed in certain cases. But many cases of articular chondrocalcinosis involve manifest radiological lesions which often appear to be secondary. This may occur in chronic inflammatory forms of chondrocalcinosis which can simulate rheumatoid polyarthritis. Careful analysis of the symptomatology should help to avoid confusion, especially when the radiograph reveals only degenerative lesions which often cause destructive damages. In other cases, a perfectly characteristic articular chondrocalcinosis is associated with typical polyarticular lesions of osteoarthritis. These cases often have the particularity of involving joints usually spared by the common arthrosic disease, especially in the upper limbs. They are also remarkable due to the amount of lytic damage. The deep destructive damage to joints during chondrocalcinosis may produced a particularly striking picture. Such damage is seen in approximately one-third of the cases. The onset is marked by sudden renewal of former arthrosic-type pain and by the development of major functional incapacity. Often, the radiograph is the only examination capable of revealing the diagnosis. The extent of bone destruction varies greatly. Sometimes it is limited to subchondral bone but in other cases underlying bony structures are also involved leading to extensive damage to the epiphysis. The distribution of lytic lesions varies. Damage may occur in the knee, the coxofemoral and the shoulder joints. Surgery is often absolutely indicated. In a number of cases of chondrocalcinosis, especially those involving the knee and the shoulder, true intraarticular foreign bodies may be encountered, opaque calcified or ossified formations simulating osteochondromatosis, existing along with destructive damages.(ABSTRACT TRUNCATED AT 400 WORDS)

[Current aspects in the arthroscopic treatment of shoulder instability].

With regard to postoperative stability of the shoulder joint, the results yielded by the various arthroscopic refixation techniques are not as good as those obtained after open operation. The aim of this paper is to analyze the reasons for this and to present a new procedure which it is hoped will improve the arthroscopic results. The main reason for the high postoperative recurrence rate after arthroscopic joint stabilization seems to be that refixation of the capsule is not performed at the level of the lesion, but above it, because of the position of the subscapularis tendon. Another reason for the poor results of arthroscopy is that the enlarged capsule cannot be shortened as desired, because the glenoid labrum is used for refixation of the capsule. To improve the arthroscopic results we suggest basic changes of the procedure in cases with severe damage to the soft tissue at the antero-inferior aspect of the glenoid and/or in cases with an enlarged capsule: refixation of the capsule should not be carried out from inside the joint but from outside the capsule. To this end, we applied the so-called extraarticular screwing technique. Refixation is achieved by inserting small cannulated titanium screws by means of a special screwdriver. No metal is placed inside the joint. This technique requires a new portal, namely the so-called antero-inferior portal, which is placed 1.5 cm inferior to the coracoid process. If the precautionary measures described are duly observed, the musculocutaneous nerve cannot be damaged. The technique allows stable refixation of the capsule in the desired length by placement of one or two small screws in the center of the Bankart lesion. Our preference is based on experience with 83 patients with recurrent shoulder instability who were operated on by arthroscopic techniques.(ABSTRACT TRUNCATED AT 250 WORDS)

Influence of adjuvant irradiation on the development of late arm lymphedema and impaired shoulder mobility after mastectomy for carcinoma of the breast.

The influence of postoperative radiation therapy on development of late arm lymphedema and shoulder joint disability following mastectomy was evaluated from a series of 57 women with operable carcinoma of the breast. The patients were divided into three groups. Common for all three groups was mastectomy and partial axillary dissection. In addition one group received postoperative irradiation plus systemic therapy and another group systemic therapy alone. The incidence of late arm lymphedema/impaired shoulder mobility was 11%/4% in the group of patients undergoing surgery alone, 46%/38% in the group of patients receiving adjuvant irradiation and 6%/12% in the group of patients receiving adjuvant systemic therapy. It is concluded that adjuvant irradiation to the axilla in patients with metastatic lymph nodes highly increases the risk of late physical sequelae following modified radical mastectomy. Adjuvant systemic therapy can be administered to high risk patients without increasing the risk of late arm lymphedema and shoulder disability.

Reliability of 3 methods for assessing shoulder strength.

The reliability of tests for isometric strength of the shoulder joint in symptomatic subjects has yet to be established. For this purpose, interrater and intrarater agreement trials were undertaken to ascertain the reliability of manual muscle tests, a handheld dynamometer, and a spring-scale dynamometer for 5 different shoulder movements in symptomatic subjects. Intraclass correlation coefficients were calculated from a random-effects model. All movements tested with the handheld dynamometer demonstrated excellent reliability for the interrater trial (rho = 0.79-0.92). Excellent reliability was also demonstrated for elevation, external rotation, and internal rotation for the intrarater trial (rho = 0.79-0.96). For the interrater trial, measurement of the lift-off maneuver with the handheld dynamometer was significantly more reliable than with manual muscle tests (P =.002). In summary, the handheld dynamometer was the most reliable and discriminatory means for assessing strength of the rotator cuff in symptomatic subjects.

Prevalence rates and odds ratios of shoulder-neck diseases in different occupational groups.

The aim of the present study was to evaluate the association and impact of occupational exposure and diseases of the shoulder and neck. Prevalence rates, odds ratios, aetiological fractions, and their confidence intervals were computed for pooled and non-pooled data of previous published reports. By comparison with office workers and farmers, dentists had an increased odds ratio for cervical spondylosis (two studies) and for shoulder joint osteoarthrosis. Meat carriers, miners, and "heavy workers" also had significantly higher rates of cervical spondylosis compared with referents. Compared with iron foundry workers, civil servants had a significant odds ratio (4.8) of cervical disc disease and a 0.79 aetiological fraction. Whether this was due to exposure or healthy worker effect was not clear. In four occupational groups with high shoulder-neck load an odds ratio of 4.0 was found for thoracic outlet syndrome with an aetiological fraction of 0.75. Rotator cuff tendinitis in occupational groups with work at shoulder level (two studies) showed an odds ratio of 11 and an aetiological fraction of 0.91. Keyboard operators had an odds ratio of 3.0 for tension neck syndrome (five studies). Unfortunately, owing to the scanty description of the work task, the exposure could be analysed only by job title. Examination of published reports shows clearly that certain job titles are associated with shoulder-neck disorders. High rates and aetiological fractions for rotator cuff tendinitis and tension neck syndrome suggest that preventive measures could be effective. Although job descriptions are brief, the associations noted suggest that highly repetitive shoulder muscle contractions, static contractions, and work at shoulder level are hazardous exposure factors. In reports of cross sectional studies of occupational shoulder-neck disorders presentation of age, exposure, and effect distribution may help for future meta-analysis.

A comparison of two surgical approaches to the scapulohumeral joint in dogs.

Two scapulohumeral arthrotomy techniques were evaluated and compared in 10 normal, young adult greyhounds. A caudolateral approach with craniodorsal retraction of the teres minor muscle (no-tenotomy) and a craniolateral approach with tenotomy of the infraspinatus tendon were each performed unilaterally in 5 dogs. The dogs were evaluated using force plate gait analysis, lameness evaluation, radiography, and goniometry for 5 weeks and then euthanatized. Tenotomy sites and sections of the humeral articular cartilage were collected from shoulder joints that had been operated on and examined microscopically. The same surgical approach has then performed on the contralateral shoulder in the cadavers and exposure of the humeral articular cartilage was measured using planimetry. Peak vertical force applied to the operated limbs in the tenotomy group was significantly less than preoperative leads on day 3 and significantly less than the no-tenotomy group on days 21 and 28. The peak vertical force applied to the operated limbs in the no-tenotomy group was not significantly different from preoperative levels during the study. Scapulohumeral arthrotomy by tenotomy of the infraspinatus resulted in decreased range-of-motion and joint extension compared with joints operated on without tenotomies, but provided significantly greater exposure to the articular surface. Scapulohumeral arthrotomy with craniodorsal retraction of the teres minor muscle did not significantly alter goniometric measurements compared with unoperated joints. Both techniques resulted in similar subjective lameness scores and caused no gross microscopic or radiographic evidence of articular cartilage damage.

[Shoulder arthroplasty for non-operated anterior shoulder instability with secondary osteoarthritis].

PURPOSE OF THE STUDY: The purpose of this study was to analyze the natural history of osteoarthritis of the shoulder joint secondary to non-operated anterior instability, to evaluate the clinical and radiological outcome after arthroplasty for this indication, and to compare results with data reported in the literature. MATERIAL AND METHODS: Twenty-eight Aequalis shoulder arthroplasties were performed for osteoarthritis secondary to anterior shoulder instability in patients who had not undergone any prior stabilizing surgical procedure. This multicentric series was reviewed retrospectively at a mean follow-up of 44 months (range 24-87 month). Preoperative and last follow-up clinical status was compared using the Constant score. Standard operative technique was used and anatomic position of the implants was achieved in 27 patients. Total shoulder arthroplasty was performed in eighteen patients and simple humeral implantation in ten. Patients were divided into two sub-groups for analysis of outcome (age at first dislocation > or < 40 years). RESULTS: There were four complications including one early loosening that required revision arthroplasty. Outcome was excellent or good in 54% of the cases. Group 1 (age at first dislocation < 40 years) included 17 patients and exhibited male predominance (13/17), young age at first dislocation (mean 28.5 years), high number of dislocations (mean 13), and a long natural history of osteoarthritis (mean 28 years). In this sub-group, imaging disclosed constructive osteoarthritis reflecting a long history. There was one case with a full-thickness tear of the supraspinatus. Outcome was excellent or good in 64% of these 17 patients (14 underwent total shoulder arthroplasty). The sub-group of 11 patients whose first dislocation occurred after the age of 40 years exhibited female predominance (9/11), a small number of dislocations (mean 1.3), and a short natural history of osteoarthritis (mean 6 years). In this sub-group, imaging disclosed six cases of basically chondrolytic osteoarthritis reflecting a short evolution. There were seven cases of full-thickness tears of the supraspinatus. Outcome was excellent or good in 36% of these 11 patients (4 underwent total shoulder arthroplasty). DISCUSSION: The forty-year age cutoff allowed us to distinguish two populations. The first population of patients whose first dislocation had occurred before the age of 40 years was predominantly male, with a long history of constructive osteoarthritis without rotator cuff tears. Most of these patients were treated with total shoulder arthroplasty which gave results similar to those obtained with arthroplasty for primary centered osteoarthritis. The second sub-group of patients aged over 40 years at the time of the first dislocation were predominantly female with a short history of minimally constructive osteoarthritis and frequent rotator cuff tears. Humeral implants were used for most of these patients and gave less favorable results than in the former sub-group, probably due to the high rate of rotator cuff tears.

[Locked posterior dislocation of the shoulder].

Whereas anterior dislocation of the shoulder is very common, posterior dislocation occurs in less than 2% of all cases. The diagnosis of posterior shoulder dislocation - especially in locked position - is difficult. The exact knowledge of the position of the humeral head within the shoulder joint is extremely significant, as the following case shows. The posterior shoulder dislocation was primarily recognized and treated correctly, while radiographics after reduction were misinterpreted. In this paper diagnostic and therapeutic measures are described.

Arthroscopic repair of glenolabral injuries with an absorbable fixation device.

In view of potential problems with metallic implants around the shoulder a bioabsorbable tact has been used in arthroscopic repair of labral lesions in the shoulder joint. We report on a consecutive series of 70 patients (71 shoulders) who had arthroscopic stabilization of Bankart lesions, SLAP lesions, and other labral detachments with the Suretac device. Minimum follow-up time was 12 months (range 12 to 27 months). Clinical outcome was assessed with the Constant score. The recurrence of dislocation or subluxation in the 42 unstable shoulders was 12% (5 of 42), and in 78% (33 of 42) the Constant score was rated good or excellent. The recurrence of dislocation in true anteroinferior dislocators was 3.2% (1 of 31). A total of 82.3% (14 of 17) of patients with SLAP repairs were rated good or excellent, and 53% (9 of 17) returned to their preinjury level of sporting activities. Eight (67%) of 12 patients with labral detachments other than Bankart and SLAP lesions were rated good or excellent, and 64% (7 of 11) returned fully to sports.

Primary motor cortex reorganization in a long-term monkey amputee.

The primary motor cortex (M1) was mapped with intracortical microstimulation (ICMS) in a 15 year-old macaque whose right upper extremity was amputated at the shoulder joint prior to 2 years of age. Movements of the right shoulder girdle and stump were evoked by ICMS throughout the left M1 upper extremity region. The size of the left M1 upper extremity region contralateral to the amputated arm was not appreciably different from the size of the right upper extremity region contralateral to the intact arm. Long stimulus trains and/or higher stimulus currents were needed to evoke detectable movements at significantly more loci in the left than in the right M1 upper extremity region. These observations would be consistent with unmasking of a high threshold representation of shoulder musculature that normally exists throughout the central core of the upper extremity region, where it underlies a lower threshold representation of the distal forelimb. Alternatively, invasion of the de-efferented distal forelimb core by surrounding shoulder representation may have occurred. Differences between the limited M1 reorganization observed in the present study and the more extensive reorganization of S1 observed in other studies may reflect fundamental differences between M1 and S1, and/or differences in the extent of de-efferentation versus deafferentation.

Descriptive report of shoulder range of motion and rotational strength 6 and 12 weeks following rotator cuff repair using a mini-open deltoid splitting technique.

STUDY DESIGN: Retrospective chart review. OBJECTIVES: To measure short-term postsurgery glenohumeral internal rotation and external rotation strength, shoulder range of motion (ROM), and subjective self-report ratings following mini-open rotator cuff repair of full-thickness rotator cuff tears. BACKGROUND: Physical therapists provide rehabilitation for patients following mini-open rotator cuff repair. Long-term outcome studies have reported a high percentage of good and excellent results following surgery; however, little has been published regarding the immediate short-term results of this procedure, during which the patient is under the direct care of the physical therapist. MATERIALS AND METHODS: Charts from 11 female and 26 male patients, with a mean +/- SD age of 57.3 +/- 9.9 years, were reviewed following rotator cuff repair, using an arthroscopically assisted mini-open deltoid-splitting approach. All patients underwent postsurgery rehabilitation by the same therapist using a standard protocol. Retrospective chart review was used to obtain descriptive profiles of shoulder joint ROM at 6 and 12 weeks postsurgery and isokinetically assessed shoulder strength at 12 weeks postsurgery. RESULTS: For the postsurgical shoulder, ROM deficits ranging between 5 degrees to 7 degrees were measured for shoulder abduction and external rotation and internal rotation at 90 degrees of abduction. The postsurgical extremity had greater flexion ROM (9 degrees ) compared to the contralateral side. Isokinetic external rotation strength deficits of 5% to 7% were present at 12 weeks postsurgery, with 2% to 11% greater internal rotation shoulder strength on the operative extremity, when compared to the other side. Patients completed the self-report section of the modified American Shoulder Elbow Surgeons (ASES) Rating Scale at 12 weeks postsurgery and scored a mean of 38.7/45.0 points. CONCLUSION: The application of early ROM and progressive strengthening following mini-open rotator cuff repair allows for the successful return of ROM and strength 12 weeks postsurgery. The results of this study provide objective data for both shoulder ROM and strength at time points during which patients are traditionally receiving physical therapy following surgery.

Articular manifestations of renal osteodystrophy.

The relationship between hyperparathyroid bone disorders and chronic renal diseases has been studied extensively for a long period of time. Zvaifler and Bywaters are the first to emphasize articular manifestations in hyperparathyroidism. Sundaram has found 30% in 80 hemodialysis patients presenting with articular disorders in hands. We reviewed routine radiographs of 258 uremia patients retrospectively and found that 36 patients had typical X-ray presentations of renal osteodystrophy. Sixteen among them (44.44%) were noted with articular involvement. Fourteen patients involved axial joints including sacroiliac, acromio-clavicular, sternoclavicular and symphysis pubis in decreasing order. Appendicular joints involvement were found in 6 patients, patellofemoral joints and small joints of hands involvement in 4 patients respectively and hip and shoulder joints in each one patient. None of the 16 patients complained joint pain. Diagnosis is easy because of the uncommon presentations of joint disorders in uremic patients. However, more knowledge about articular manifestations of renal osteodystrophy may eliminate the unnecessary investigations.

[Leading symptom shoulder pain].

Pain in the shoulder should prompt a systematic clinical examination that adheres closely to the functional anatomy. The basic examination of the shoulder joint comprises active and passive movements and isometric resistance tests with the aid of which external and internal rotation and abduction/adduction can be investigated. The results of these tests provide the physician with a "pattern of findings" which unequivocally identifies the pain-triggering structure. Accordingly, shoulder pain can be classified into four categories as proposed by Cyriax. As treatment, intra-articular injections of corticoids or local anesthetics as determined by findings, where necessary supported by physiotherapeutic measures. Rupture of a tendon, in particular in the case of an active patient, is an indication for surgery.

[Subacromial impingement syndrome in athletes: prevention and exercise programs].

The shoulder joint, the most mobile joint in the human body, is at greater risks for injuries. Several factors contribute to shoulder impingement syndrome including rotator cuff weakness, capsular tightness, poor scapulohumeral rhythm, and muscle imbalance of the scapular upward rotation force couple. Rehabilitation and training of the shoulder in throwing and overhead athletes has dramatically improved during the last decade. There are numerous reasons for rapid return to athletic training and competition. A preventive program designed for the glenohumeral joint is mainly based on an appropriate preparation, which should include overall body conditioning, flexibility, and strengthening of the musculature around the glenohumeral joint and the scapula. Activity levels represent a helpful guide in determining an appropriate rehabilitation program for shoulder patients ranging from disabled to those competing at the highest levels of athletics. This article discusses issues related to prophylactic measures, non-operative treatment, postoperative treatment, and rehabilitation programme of impingement syndrome in athletes.
