[A painless technique for reposition of anterior shoulder dislocation]

No Sedation, No Traction, and No Need for Assistance: Analysis of New Prakash's Method of Shoulder Reduction

Materials and Methods

A total of 19 patients who were admitted to the emergency department with the diagnosis of anterior shoulder dislocation participated in this study. The diagnosis of shoulder dislocation was established in the emergency department with physical examination and anteroposterior shoulder radiography. The method was applied only once to the patients in the sitting position by the same physician without using any help, traction, anesthesia, analgesia, and myorelaxant.

Results

The mean age of the patients was 37.3 ± 13.1 years. Among them, 36.8% (n=7) were female and 63.2% (n=12) were male. Recurrent dislocations were observed in 21.1% (n=4) of the patients. The success rate of the method was 94.7% (n=18). No complication was noted in the patients. The mean procedure time was 243 ± 38 seconds.

Conclusion

Prakash's method is a safe method for anterior shoulder dislocations that can be quickly performed with no need for sedation, assistance, and traction and has a high success rate.

Shoulder Dislocations in the Emergency Department: A Comprehensive Review of Reduction Techniques

BACKGROUND

Shoulder dislocations are a common presentation to the emergency department and one of the most frequent types of joint dislocations. Studies have found that delays from presentation to first reduction attempt and failed attempt at initial reduction are associated with lower rates of overall reduction success.

DISCUSSION

This article reviews 26 total reduction techniques, as well as a variety of modifications to these techniques. Each technique has distinct advantages and limitations associated with its use. While there are limited data comparing specific techniques, the individual success rates of most maneuvers range from 60-100%.

CONCLUSION

It is essential for emergency physicians to be familiar with multiple different reduction techniques in case the initial reduction attempt is unsuccessful or patient-specific characteristics limit the ability to perform certain techniques. This article reviews several reduction maneuvers for shoulder dislocations, variations on these techniques, and advantages and disadvantages for each approach. It is intended to serve as a resource for those interested in expanding their knowledge of shoulder reduction techniques.

Comparison between new modified external rotation method and external rotation method for reduction of ASD

INTRODUCTION

Dislocation of the shoulder joint is common and is mainly anterior. Several reduction methods have been described and the external reduction method (ERM) is one of the newest. We modified the ERM by making some additions in hopes to develop a less painful, quick and simple method. The aim of this study was to compare the new modified external rotation reduction method (MERM) with ERM in acute anterior shoulder dislocations (ASD).

METHODS

A total of 62 patients with ASD were classified randomly into 2 groups. The reduction was performed with MERM in one group and with ERM in the other group and the results were compared. Patients' pain scores, reduction time, success rate of the reduction methods, age, sex, dislocation side, dislocation time, previous dislocations history, injury mechanism, any complications, reduction time and neurovascular examination were collected. Parametric and nonparametric analyses were used to compare MERM and ERM.

RESULTS

The study cohort consisted of 62 patients (52 males, 10 females; mean age, 35 years; age range, 18-73 years) who were randomly assigned to treatment with the MERM (n = 32) or the ERM (n = 30). There was a statistically significant difference between the two methods in terms of time, and the MERM can be applied much faster than ERM (1.34 ± 1.41 min vs 3.05 ± 1.93 min; p < 0.001). The intra-reduction VAS pain score was not significantly in patients who were treated with MERM (85.31 ± 10.39 vs. 78.33 ± 16.54; p = 0.122).

CONCLUSION

MERM can be an alternate method compared to the ERM for the reduction of ASD.

A systematic and technical guide on how to reduce a shoulder dislocation

OBJECTIVES

Our objective is to provide a systematic and technical guide on how to reduce a shoulder dislocation, based on techniques that have been described in literature for patients with anterior and posterior shoulder instability.

MATERIALS AND METHODS

A PubMed and EMBASE query was performed, screening all relevant literature on the closed reduction techniques. Studies regarding open reduction techniques and studies with fracture dislocations were excluded.

RESULTS

In this study we give an overview of 23 different techniques for closed reduction and 17 modifications of these techniques.

DISCUSSION

In this review article we present a complete overview of the techniques, that have been described in the literature for closed reduction for shoulder dislocations. This manuscript can be regarded as a clinical guide how to perform a closed reduction maneuver, including several technical tips and tricks to optimize the success rate and to avoid complications.

CONCLUSION

There are 23 different reduction techniques with 17 modifications of these techniques. Knowledge of the different techniques is highly important for a good reduction.

A simple and gentle technique for reduction after anterior shoulder dislocation

BACKGROUND

Anterior shoulder dislocation (ASD) is a common sports injury. The goal of this study was to evaluate a new procedure for reduction after ASD with respect to success rate, the need for medication for muscle relaxation, sedation, and application of pain medication and put it into context to a systematic literature review.

PATIENTS AND METHODS

We retrospectively evaluated the new method in 263 patients in an Austrian skiing area from December 2005 till April 2009. We included patients with unilateral ASD and excluded those with a combined trauma and consecutive admission to hospital.

RESULTS

The new procedure is performed in a supine position, the therapist takes the patients hand of the injured limb with his one hand and with his other hand counter holds against the acromion. Then he enhances the traction on the upper limp by using his trunk as a kind of fulcrum. With eye contact and instructions to relax, the therapist is able to detect the muscular tension, so that he can adjust the amount of traction accordingly. The presented procedure was successful in all reported cases. For 196 patients (74.5 %) no medication for muscle relaxation, sedation, or pain medication were needed.

CONCLUSION

The new method is a promising option to popular techniques for reduction of anterior shoulder dislocations. The benefits of this protocol are a gentle and simple application of the procedure as well as an easy acquisition.

Reduction of Acute Shoulder Dislocations in a Remote Environment: A Prospective Multicenter Observational Study

OBJECTIVE

Acute dislocations of the glenohumeral joint are common in wilderness activities. Emergent reduction should take place at the site of trauma to reduce the patient's pain and the risk of vascular and neurological complications. A limited number of reduction methods are applicable in remote areas. The aim of this study is to present our method of reduction of anterior shoulder luxation that is easily applicable in remote areas without medication, adjuncts, and assistants and is well tolerated by patients.

METHODS

A prospective observational study was conducted during a 5-year period. The patients included underwent closed manual reduction with our technique. After each reduction, the physician who performed the reduction completed a standardized detailed history, and reexamined the patient (for acute complications). The patients were contacted 6 months after the trauma to investigate long-term postreduction complications.

RESULTS

Reduction was achieved with our method in 39 (100.0%) of 39 patients. The mean pain felt during our reduction procedure was rated 1.7 ± 1.4 (on a scale of 10) using the visual analog scale scoring system. No complications were noted before or after the reduction attempts. We did not find any long-term complications.

CONCLUSIONS

The reduction method presented in the present study is an effective method for the reduction of acute shoulder luxations in remote places. Our data suggest that this method could be applied for safe and effective reduction of shoulder dislocation.

Neurovascular complications due to the Hippocrates method for reducing anterior shoulder dislocations

In spite of the fact that the Hippocrates method hardly has been evaluated in a scientific manner and numerous associated iatrogenic complications have been reported, this method remains to be one of the most common techniques for reducing anterior shoulder dislocations. We report the case of a 69-year-old farmer under coumarin anticoagulant therapy who sustained acute first time anterior dislocation of his dominant right shoulder. By using the Hippocrates method with the patient under general anaesthesia, the brachial vein was injured and an increasing hematoma subsequently caused brachial plexus paresis by pressure. After surgery for decompression and vascular suturing, symptoms declined rapidly, but brachial plexus paresis still was not fully reversible after 3 mo of follow-up. The hazardousness of using the Hippocrates method can be explained by traction on the outstretched arm with force of the operator’s body weight, direct trauma to the axillary region by the physician’s heel, and the topographic relations of neurovascular structures and the dislocated humeral head. As there is a variety of alternative reduction techniques which have been evaluated scientifically and proofed to be safe, we strongly caution against the use of the Hippocrates method as a first line technique for reducing anterior shoulder dislocations, especially in elder patients with fragile vessels or under anticoagulant therapy, and recommend the scapular manipulation technique or the Milch technique, for example, as a first choice.

Humerus axial traction with acromial fixation reduction maneuver for anterior shoulder dislocation

BACKGROUND

Many techniques have been described for the reduction of anterior glenohumeral dislocation, but each of the techniques has its disadvantages. A new shoulder reduction technique is needed to overcome these disadvantages.

DESCRIPTION

An alternate technique of humerus axial traction with acromial fixation is presented. The technical description of this procedure focuses on the pre-reduction and post-reduction process. The use of acromial countertraction, the choice of the most loosely packed position of the shoulder joint, and the operator's ability to reduce muscle spasm are the main principles discussed.

CONCLUSION

This modified technique increases the possibilities for the reduction of shoulder dislocation in different clinical situations.
