Bilateral anterior dislocation of the shoulders with proximal humeral fractures: a case report.

Bilateral simultaneous anterior dislocation of the shoulders with bilateral 3-part fracture of the proximal humeri is unusual. A 42-year-old man presented with pain and restriction of movement on both shoulders. He was injured by a heavy object falling over his back while he was leaning forward holding an overhead bar. His arms were abducted and externally rotated. The injury was not correctly diagnosed, and the patient was treated with repeated manipulations and splintage for 2 weeks. Radiological examination revealed bilateral anterior dislocation of the shoulders with displaced 3-part fractures of the proximal humeri involving the shaft, greater tuberosity, and head. The patient was treated with open reduction and internal fixation through a deltopectoral approach using multiple Kirschner wires. The shoulders were kept immobilised for 3 weeks until the removal of the wires. The patient was able to resume work 3 months after surgery. He had an excellent and comfortable range of motion in both shoulders at one-year follow-up.

Shoulder pain after stroke: a review of the evidence base to inform the development of an integrated care pathway.

BACKGROUND: Shoulder pain is a common complication of stroke. It can impede rehabilitation and has been associated with poorer outcomes and prolonged hospital stay. This systematic review was undertaken to inform the development of an evidence-based integrated care pathway (ICP) for the management of hemiplegic shoulder pain (HSP). AIMS AND OBJECTIVES: 1) To provide a background understanding of the functional anatomy of the shoulder and its changes following stroke. 2) To review the literature describing incidence and causation of HSP and the evidence for factors contributing to its development. 3) To appraise the evidence for effectiveness of different interventions for HSP. METHODS: Data sources comprised a computer-aided search of published studies on shoulder pain in stroke or hemiplegia and references to literature used in reviews (total references = 121). MAIN FINDINGS: Although a complex variety of physical changes are associated with HSP, these broadly divide into 'flaccid' and 'spastic' presentations. Management should vary accordingly; each presentation requiring different approaches to handling, support and intervention. (1) In the flaccid stage, the shoulder is prone to inferior subluxation and vulnerable to soft-tissue damage. The arm should be supported at all times and functional electrical stimulation may reduce subluxation and enhance return of muscle activity. (2) In the spastic stage, movement is often severely limited. Relieving spasticity and maintaining range requires expert handling; overhead exercise pulleys should never be used. Local steroid injections should be avoided unless there is clear evidence of an inflammatory lesion. CONCLUSIONS: HSP requires co-ordinated multidisciplinary management to minimize interference with rehabilitation and optimize outcome. Further research is needed to determine effective prophylaxis and document the therapeutic effect of different modalities in the various presentations. Development of an integrated care pathway provides a reasoned approach to management of this complex condition, thus providing a sound basis for prospective evaluation of different interventions in the future.

Current concepts in the diagnosis and treatment of shoulder instability in athletes.

Glenohumeral joint instability is a fairly common clinical disorder in athletes, especially in sports that involve the throwing motion. The direction of shoulder instability can be anterior, inferior, posterior, or multidirectional. The cause can be trauma, congenital laxity, or voluntary muscle action. Normal shoulders that have been disrupted by injury respond well to surgical correction. Shoulders that have inherently lax supporting structures, as found in patients with atraumatic and voluntary dislocation, have less consistent success with surgical repair. A common condition encountered in the shoulder of a throwing arm is anterior subluxation, which can be diagnosed by the positive apprehension sign and confirmed by arthroscopy. A torn glenoid labrum is a common injury also. Improvement in the diagnosis and treatment of shoulder disorders has been made recently by arthroscopy which allows direct visualization of the joint; many conditions can now be corrected by means of arthroscopic surgery. Radiographic techniques have also been improved.

The role of atmospheric pressure in stabilising the shoulder. An experimental study.

The role of atmospheric pressure in providing static stability of the shoulder was studied experimentally in 24 cadaveric shoulders. Atmospheric air was allowed to enter the joint after puncturing the capsule. Three types of experiment were performed: in the first, the capsule was punctured after sequential division of the muscles; in the second, atmospheric air was let in by percutaneous puncture of of the capsule without dividing the muscles; and in the third, air was first let into the joint by percutaneous puncture of the capsule and then the muscles of the shoulder were divided. It was found that the intact shoulder subluxated after percutaneous puncture even without division of the overlying muscles or the capsule. Our findings suggest that negative pressure and muscle tone are the main static stabilisers of the shoulder, rather than the joint capsule.

Deformities of the shoulder in infants younger than 12 months with an obstetric lesion of the brachial plexus.

We performed a prospective study using MRI in 16 consecutive infants with a mean age of 5.2 months (2.7 to 8.7) who had shown inadequate recovery from an obstetric lesion of the brachial plexus in the first three months of life, in order to identify early secondary deformities of the shoulder. Shoulders were analysed according to a standardised MRI protocol. Measurements were made of the appearance of the glenoid, glenoid version and the position of the humeral head. The appearance of the glenoid on the affected side was normal in only seven shoulders. In the remainder it was convex in seven and bioconcave in three. The degree of subluxation of the humeral head was significantly greater (p = 0.01) in the affected shoulders than in normal shoulders (157 degrees v 170 degrees). The presence of an abnormal appearance of the glenoid, retroversion of the glenoid and subluxation of the humeral head increased with age. There was a statistical difference (p = 0.05) between infants younger than five months and those who were older.

[A novel device for active shoulder rehabilitation with glenohumeral traction or compression].

The equipment available for rehabilitation of patients with joint conditions still lacks a device that, in common with usual physiotherapeutic measures (manipulation, proprioceptive neuromuscular facilitation, Bobath therapy), is based on traction and/or compression or oscillating forms. The novel "Shoulder Rotator" is such a simple device for the variable treatment of shoulder disorders in all three spatial dimensions. After individual instruction, the patient performs rotating glenohumeral exercises with simultaneous glenohumeral joint traction, compression, or oscillations against static or dynamic resistance. The "Shoulder Rotator" is similar to the established continuous passive motion device for the shoulder and is mounted on a mobile chair. The electronic device control is computerised and permits a wide variety of treatment options, individual regimes, and documentation. The oscillating, compression/distraction mode of operation provides an analgesic effect. The isolated compression mode along the rotatory axis enables conditioning of joint proprioception. The distraction mode along the rotatory axis facilitates muscular relaxation. Resistive rotatory exercises strengthen the rotatory glenohumeral muscles and help centre the humeral head in the glenoid. In addition to the advantage of adding documentation of treatment progress as required for evidence-based medicine, this novel device may bring about a cost-effective, genuine quality improvement in shoulder rehabilitation.

The external rotation method for reduction of acute anterior dislocations and fracture-dislocations of the shoulder.

BACKGROUND: Several methods of reducing an acute anterior dislocation of the shoulder have been described. The aim of this study was to assess the effectiveness of the external rotation method in the reduction of acute anterior shoulder dislocations with and without fractures of the greater tuberosity and to evaluate the causes of failure. METHODS: Senior and junior orthopaedic residents attending in the Emergency Department were instructed in the external rotation method for the reduction of a shoulder dislocation in a classroom setting. Forty patients with an acute anterior dislocation of the shoulder, with or without an associated fracture of the greater tuberosity, who were treated with this method were evaluated prospectively. Data sheets completed by the orthopaedic residents when this method was used were evaluated with regard to the type of dislocation, the effectiveness of the procedure in achieving reduction, the need for premedication, the ease of performing the reduction, and complications, if any. RESULTS: Of the forty patients, thirty-six had a successful reduction. No premedication was required in twenty-nine patients who had a successful reduction, and the average time required for reduction in twenty patients was less than two minutes. Only four patients reported severe pain during the process of reduction. The method was not successful in four patients, two of whom had a displaced fracture of the greater tuberosity. CONCLUSIONS: The external rotation method for the reduction of an acute anterior dislocation of the shoulder is a safe and reliable method that can be performed relatively painlessly for both subcoracoid and subglenoid dislocations provided that a displaced fracture of the greater tuberosity is not present.

Arthroscopic surgery of the shoulder.

Arthroscopy of the shoulder is well established as a diagnostic procedure. It carries a greater degree of accuracy than conventional imaging techniques and in addition allows the assessment of instability and the degree of mechanical derangement inside the joint. Arthroscopic surgical procedures in the shoulder are in the developing stage. Arthroscopic acromioplasty for impingement syndrome has been shown to be a safe, effective procedure and probably better than conventional surgery. In the older patient, arthroscopic debridement of the rotator cuff is very effective at relieving pain. Arthroscopic surgery for removal of loose bodies and of a torn glenoid labrum would be the current recommended procedure rather than open surgery. Other rapidly developing areas of potential benefit are in the arthroscopic stabilisation of the dislocating shoulder and synovectomy of the shoulder in rheumatoid arthritis and other synovial conditions. The role of arthroscopy in the frozen shoulder is not clearly established although certainly it is the diagnostic tool of first choice in this condition.

Using abduction and external rotation of the shoulder to increase the sensitivity of MR arthrography in revealing tears of the anterior glenoid labrum.

OBJECTIVE: The purpose of this study was to compare oblique axial MR arthrograms obtained with the patient's shoulder in abduction and external rotation (ABER) position with conventional axial MR arthrograms obtained with the patient's arm in neutral position and the shoulder not rotated in revealing tears of the anterior glenoid labrum (AGL). SUBJECTS AND METHODS: MR arthrography of the shoulder that included an additional oblique axial imaging sequence with the patient in the ABER position was performed in 256 patients. Assessment of AGL integrity with patients in both conventional axial and ABER positions was made before surgery. These assessments were compared with the surgical findings. RESULTS: Of the 92 patients who underwent surgery, AGL tears were found in 27. Conventional axial MR arthrograms revealed 13 tears (sensitivity, 48%; specificity, 91%). A separate review of MR arthrograms obtained with patients in the ABER position revealed 24 tears (sensitivity, 89%; specificity, 95%). Reviewed together, axial MR arthrograms and MR arthrograms obtained with patients in the ABER position revealed 26 tears (sensitivity, 96%; specificity, 97%). CONCLUSION: Oblique axial MR arthrograms obtained with the patient's shoulder in the ABER position were significantly more sensitive in revealing AGL tears (p = .005) than were conventional axial MR arthrograms obtained with the patient's aim in a neutral position and the shoulder not rotated.

Current concepts in the rehabilitation of the athletic shoulder.

The rehabilitative process of the overhead athlete represents a significant challenge to the clinician. Overhead athletes (thrower, tennis player, swimmer) repetitively subject their shoulder joints to high microtraumatic stresses that, due to the accumulative effects, may lead to a variety of shoulder injuries. This type of athletic patient exhibits uniquely specific physical characteristics, such as hypermobility of the anterior shoulder capsule, excessive external rotation, hypomobility of the posterior capsule, limited internal rotation, and generalized ligamentous laxity of the glenohumeral joint. However, the overhead athlete must exhibit functional stability for pain-free sports participation. Functional stability is accomplished through the proficient balance of static (passive) and dynamic (active) stabilizers. During the rehabilitation process, various concepts, such as neuromuscular control, proprioception, force couple efficiency, plyometrics, eccentrics, and scapular stability, can enhance dynamic functional stability for the overhead athlete. The evaluation and treatment of the shoulder patient is in perpetual change, and the purpose of this paper is to discuss several current concepts in the rehabilitative treatment of the athletic shoulder patient.

Clinical implications of secondary impingement of the shoulder in freestyle swimmers.

Swimming has become a popular recreational activity as well as a highly competitive sport in the United States. The repetitive nature of swimming can predispose the shoulder to mechanical impingement and microtrauma, which may lead to laxity, rotator cuff fatigue, and subsequent secondary impingement. Improper stroke mechanics can place the swimmer's shoulder at further risk. The purpose of this paper is to describe the pathology of secondary impingement in freestyle swimmers and to discuss the clinical implications for rehabilitation of swimmers with the pathology. A thorough subjective and objective evaluation is necessary to design a successful rehabilitation program. The rehabilitation program for swimmers with secondary impingement includes modification of training, flexibility, range of motion, strengthening, and mobilization as indicated. Functional and proprioceptive training may also be useful techniques in the rehabilitation of swimmer's shoulder. Improper stroke mechanics can also have clinical implications on swimmer's shoulders with secondary impingement. The clinical implication of secondary impingement in freestyle swimmers suggests that the primary goal of rehabilitation is to promote equilibrium of the shoulder complex while accounting for the demands of the sport.

Posture in patients with shoulder overuse injuries and healthy individuals.

Assessment of posture is an integral component of patient evaluation with shoulder overuse injuries. However, the professional literature contains relatively few studies that have assessed the relationship between posture, function, and injury. The purpose of this study was to determine the relationship and differences in postural variables within and between subjects with overuse injuries to the shoulder of healthy subjects. Thirty patient subjects and 30 healthy subjects matched for age and gender were recruited. Scapular protraction and rotation, forward head position, midthoracic curvature, and passive humeral elevation in the plane of the scapula were measured randomly in standing. All measurement techniques were standardized and validated. Intrarater and interrater reliability for all clinical measures were established before data collection. Forward head position was significantly greater (p < .001) in the patient group than the healthy group; humeral elevation was significantly greater (p < .001) in the healthy group than in the patient group and in the uninvolved shoulders (p < .01) than the involved shoulders within the patient group. Scapular protraction, rotation, midthoracic curvature, and scapular symmetry were not significantly different between groups. Scapula protraction and rotation were significantly related (p < .05) in the patient group. No other postural variables were related. Conclusions regarding the influence of posture to shoulder injury are inconclusive based on several confounding variables that may have affected the outcome.

Shoulder instability: management and rehabilitation.

Shoulder dislocation and subluxation occurs frequently in athletes with peaks in the second and sixth decades. The majority (98%) of traumatic dislocations are in the anterior direction. The most frequent complication of shoulder dislocation is recurrence, a complication that occurs much more frequently in the adolescent population. The static (predominantly capsuloligamentous and labral) and dynamic (neuromuscular) restraints to shoulder instability are now well defined. Rehabilitation aims to enhance the dynamic muscular and proprioceptive restraints to shoulder instability. This paper reviews the nonoperative treatment and the postoperative management of patients with various classifications of shoulder instability.

Reliability of function-related tests in patients with shoulder pathologies.

STUDY DESIGN: Nonexperimental. OBJECTIVE: To investigate the intertester and intratester reliability of a battery of function-related tests in patients with shoulder pathologies and associated reduced range of motion. BACKGROUND: A battery of function-related tests has the potential to complement assessment of functional limitation in patients who have shoulder pathologies. METHODS AND MEASURES: Three function-related tests (hand to neck, hand to scapula, and hand to opposite scapula) were conducted on 46 patients with shoulder pathologies, and 46 age- and gender-matched control subjects. The tests were performed by 2 independent physiotherapists to test intertester reliability. Intratester reliability was examined by investigating the reproducibility of the tests performed twice, with 3 to 5 days between tests, by the same physiotherapist. Comparison of the scores on the function-related tests between patients and controls was evaluated. A correlation matrix was calculated to test the level of association among the tests. RESULTS: Intratester and intertester reliability on the 3 tests (weighted K) varied from 0.83 to 0.90. The patient's test performances were decreased in comparison to the control group. The correlation matrix demonstrated a level of associations among the 3 tests varying from r = 0.64 to r = 0.66. CONCLUSION: The results of this study indicate that function-related tests are reliable and could be used in clinical practice to document reduced function of the shoulder. The level of association among the tests indicates that each test measured different aspects of shoulder function.

Trapezius transfer for shoulder paralysis. 6 patients with brachial plexus injuries followed for 1 year.

We transferred the trapezius with its bone insertion to the proximal humerus in 6 patients for treatment of a paralytic shoulder secondary to traumatic lesions of the brachial plexus. After 1 year, the shoulder abduction was improved from average 13 degrees (0 degrees-30 degrees) preoperatively to 76 degrees (50 degrees-100 degrees) postoperatively, and the shoulder flexion from 18 degrees (0 degrees-40 degrees) to 78 degrees (45 degrees-110 degrees) postoperatively. All the patients were satisfied with the outcome. We consider that transfer of the trapezius in a paralytic shoulder after brachial plexus injury gives a better outcome than shoulder fusion.

Shoulder pain in hemiplegia.

Development of a painful shoulder in the hemiplegic patient is a significant and serious problem, because it can limit the patient's ability to reach his or her maximum functional potential. Several etiologies of shoulder pain have been identified, such as immobilization of the upper extremity, trauma to the joint structures, including brachial plexus injuries, and subluxation of the gleno-humeral joint. A review of the literature explains the basic anatomy and kinesiology of the shoulder complex, the various etiologies of hemiplegic shoulder pain, and the pros and cons of specific treatment techniques. This knowledge is essential for the occupational therapist to evaluate effectively techniques used to treat the patient with hemiplegic shoulder pain. More effective management of this problem will facilitate the patient's ability to reach his or her maximum functional potential.

Development of a shoulder pain and disability index.

A shoulder pain and disability index (SPADI) was developed to measure the pain and disability associated with shoulder pathology. The SPADI is a self-administered index consisting of 13 items divided into two subscales: pain and disability. Thirty-seven male patients with shoulder pain were used in a study to examine the measurement characteristics of the SPADI. Test-retest reliability of the SPADI total and subscale scores ranged from 0.6377 to 0.6552. Internal consistency ranged from 0.8604 to 0.9507. SPADI total and subscale scores were highly negatively correlated with shoulder range of motion (ROM) supporting the criterion validity of the index. Principal components factor analysis with and without varimax rotation supported the construct validity of the total SPADI and its subscales. High negative correlations between changes in SPADI scores and changes in shoulder ROM indicated the SPADI detected changes in clinical status over short time intervals. The SPADI should prove useful for both clinical and research purposes.

Prospective longitudinal analysis of postoperative shoulder function : a ten-year follow-up study of full-thickness rotator cuff tears.

BACKGROUND: Rotator cuff repair is associated with good short or mid-term results, but to date there have been no long-term functional outcome studies demonstrating durability of results over time. In most long-term studies, the results have been compared with those of historical controls or with those of other, short-term follow-up studies. The purpose of the present prospective study was to evaluate short and long-term shoulder function after surgical repair in a single population of patients in order to follow changes over time. METHODS: Thirty-three patients underwent surgery, performed by one surgeon, for the treatment of a chronic, symptomatic, full-thickness rotator cuff defect. Data were obtained from questionnaires and physical examinations preoperatively, at two years, and at ten years. Identical standardized pain and function questionnaires were used and clinical evaluation was performed in a consistent fashion at all time-periods. The activity level, Constant score, level of disability, shoulder function score, and patient's subjective rating of the outcome were determined at the time of the final follow-up and compared with the same parameters at the two-year follow-up examination in order to determine if early results change with time. RESULTS: At the ten-year follow-up examination, there was no change in the raw Constant score determined at the two-year examination. When the Constant score was normalized for expected age-related changes, the percentage of patients who had a satisfactory result at ten years was even greater than the percentage at two years. Activity level decreased significantly over the time-period (p = 0.005). At the final follow-up examination, twelve patients worked at the same occupation as they had when the two-year examination was performed, two worked at a less strenuous occupation, and the remaining patients were retired. Only two patients retired because of problems related to the shoulder. The level of disability decreased over the study period, and there was a small improvement in the patients' self-assessment shoulder function score. The patients' subjective assessment of the outcome remained unchanged. CONCLUSIONS: The results of open rotator cuff repair for chronic tears do not deteriorate with time (ten years). The level of disability decreases, presumably because of a concurrent decrease in the activity level and in the demand on the shoulder as the patient ages. It is important to consider age-related changes when assessing the final outcome.
