The Milch technique for reduction of anterior shoulder dislocations in an accident and emergency department.

Following the introduction of the Milch technique as the preferred method of reduction of anterior shoulder dislocations in an A&E department, a retrospective study of the technique was carried out. A total of 187 patients with anterior shoulder dislocations were included. The Milch technique was attempted in 142 cases with a success rate of 86%. There was no statistical difference in the success rates of junior and senior staff. In 73% of the Milch cases either no analgesia or sedation or Entonox alone was used. This study shows that the Milch technique can successfully be used by inexperienced staff to reduce dislocated shoulders with a reduction in the requirements for sedation and anaesthetics.

A prevalence study of recurrent shoulder dislocations in young adults.

The computerized database of the Israeli Defence Forces Medical Corps monitors recurrent shoulder dislocations before citizens are eligible for military induction, during the years of regular military service, and during the time of eligibility for reserve army service. With the computerized database of the Israeli Defence Forces Medical Corps, between the years of 1978 to 1995 the prevalence rate of subjects with recurrent shoulder dislocations less than or equal to 21 years of age was found to be 19.7 of 10,000 for men and 5.01 of 10,000 for women. The prevalence rate of subjects with a history of shoulder dislocations in the male population between the ages of 22 and 33 years was 42.4 of 10,000. Forty-four percent were judged to be sufficiently unstable to warrant surgery, but only 55% of these actually underwent surgery. These epidemiologic data may be important if arthroscopic shoulder surgery is being considered after a first shoulder dislocation.

Brachial plexus injury after anterior shoulder dislocation: a case report.

Brachial plexus injury is a rare complication of anterior dislocation of the shoulder: nine cases have been reported in the literature. We report a unique case of anterior dislocation of the shoulder with associated brachial plexus palsy involving the posterior and medial cords. This is the first reported case of such an injury. Previous case reports of brachial plexus palsy in association with anterior shoulder dislocation are reviewed. Conservative management affords good recovery from these injuries over a period of up to 18 months.

The role of arthroscopy in chronic anterior shoulder dislocation: technique and early results.

Dislocation that lasts longer than 3 weeks is called chronic or unreduced shoulder dislocation. Treatment alternatives can be closed reduction, open reduction, resection arthroplasty, prosthesis, arthrodesis, and no therapy. The English-language literature includes no evidence on arthroscopic reduction for the treatment of unreduced shoulder dislocation. The goal of our study was to present our technique and period results on the arthroscopic reduction we performed in 2 cases 4 and 5 weeks after anterior shoulder dislocation. Reduction could not be achieved by closed reduction under anesthesia. With arthroscopic visualization, adhesions within the joint were released with blunt dissection. Repeat reduction attempts were unsuccessful in these 2 cases. Labroligamentous lesions of the inferior glenohumeral ligament were repaired using 3 absorbable tacks. On the second day after the surgery, isometric exercises were started. The results were evaluated using a 100-unit test recommended by Rowe and Zarins (80 units in case 1; 85 units in case 2). Reduction of chronic unreduced shoulder dislocations using arthroscopy is an alternative technique for selected patients. It also allows repair and treatment of the intra-articular pathology in the joint and makes early postoperative rehabilitation possible.

Shoulder dislocation in skiing: choice of surgical method depending on the degree of humeral retrotorsion.

Shoulder dislocation is one of the typical upper extremity injuries in skiing, first following a violent accident but quite frequently recurring without new trauma. This article discusses the retrotorsional angle of the humerus as an etiological factor in the occurrence of an initial dislocation and as a triggering element for its recurrence. It focuses on the consequences to be drawn for the surgical treatment of recurrent shoulder dislocation. A technique for exact determination of the humeral angle of retrotorsion by X-ray is presented. In patients with recurrent anterior dislocations of the shoulder joint, the retrotorsional angle of the humerus is pathologically reduced as compared to the control group. The method of surgical therapy is determined by the individual deviance from the average value.

Shoulder dislocations in patients older than 40 years of age.

Shoulder dislocations in patients over 40 years of age are common and are frequently associated with serious injuries to adjacent structures. Associated injuries such as brachial plexus injury, rotator cuff tear, axillary artery injury, fractures about the shoulder, and recurrent dislocation can make shoulder dislocations challenging problems for the clinician. Early diagnosis and treatment of associated injuries and treatment complications are the mainstays in prevention of morbidity and, even, mortality.

Prospective evaluation of the scapular manipulation technique in reducing anterior shoulder dislocations.

STUDY OBJECTIVE: To evaluate the speed, efficacy, and safety of the scapular manipulation technique in reducing acute anterior shoulder dislocations. DESIGN: Prospective study. SETTING: Urban emergency department with an annual census of 65,000 patients. PARTICIPANTS: Forty-eight adult patients with acute anterior shoulder dislocation. INTERVENTIONS: Patients had an initial neurovascular and radiographic evaluation performed. They were sedated with IV fentanyl and midazolam. The shoulder was reduced using the scapular manipulation technique. The patient was re-evaluated for any evidence of complication. The total dose of analgesic required and time to reduction were recorded. RESULTS: The scapular manipulation technique was successful in 46 of 48 (96%) cases. The average time to reduction was 6.05 minutes, and no complications were detected. Average doses of 1.83 mg midazolam and 204 micrograms fentanyl were required for reduction. CONCLUSION: The scapular manipulation technique is a very fast, effective, safe method of reducing anterior shoulder dislocations in the ED.

[The value of MR tomography in acute shoulder dislocations].

24 patients up to two weeks after primary traumatic shoulder dislocation were examined at 0.5 and 1.5 T. Surgical and/or arthroscopic correlation was available in 13, CT-arthrographic correlation in 16 patients. A joint effusion allowing sufficient evaluation of the capsulolabral complex was present in 21/24 (87.5%) cases. 11/14 patients with combined dislocated detachments of the glenoid labrum and capsular lesions were subsequently operated upon. Marrow edema of the humeral head was found in 16/19 Hill-Sachs lesions and in 4/5 fractures of the greater tuberosity. Two patients presented with a lesion of the long biceps tendon associated with rotator cuff tears and were also subsequently operated upon. MRI performed shortly after primary traumatic shoulder dislocation allows a comprehensive evaluation of the intraarticular lesions and decisively influences further therapy.

Necessity of radiographs in the emergency department management of shoulder dislocations.

STUDY OBJECTIVE: To determine the necessity of radiographs in the emergency department management of patients with suspected shoulder dislocation. METHODS: A prospective, observational study was conducted at a university-affiliated, Level I trauma center ED with an emergency medicine residency program. Physicians entered all patients with a suspected shoulder dislocation and reported whether they were certain that the patient's shoulder was dislocated or reduced, before obtaining radiographs. Outcome measures were the assessments of joint position and the radiology reports of prereduction and postreduction films. RESULTS: One hundred four patients were enrolled in the study, including 98 with shoulder dislocations, and 191 physician assessments were performed (96 prereduction, 95 postreduction). Twenty-eight patients had recurrent dislocations with an atraumatic mechanism (group 1), and 76 had no prior dislocation or a blunt mechanism of injury (group 2). There were no fractures in group 1 patients; the accuracy of confident assessments was 100% (95% confidence interval 92% to 100%). In group 2, the accuracy of confident assessments was 98% (95% confidence interval 94% to 100%). Incorrect assessments occurred only in patients with fractures. A derived algorithm would have reduced radiographs by 51%. CONCLUSION: Physicians are highly accurate in the clinical determination of shoulder dislocation and relocation. Radiographs should be obtained when the physician is uncertain of dislocation or reduction. Prereduction films should be obtained for patients with a blunt traumatic mechanism of injury, and postreduction for those found to have a fracture-dislocation. However, postreduction films add little in patients without fractures, and neither prereduction nor postreduction films are likely to affect the ED management of patients with recurrent dislocation by an atraumatic mechanism. Prospective validation of the derived algorithm is suggested.

Incidence of anterior shoulder dislocation in Olmsted County, Minnesota.

The records of all Olmsted County, Minnesota residents treated for an initial traumatic anterior shoulder dislocation during a ten-year period were reviewed to study the incidence and natural history of this condition. One hundred twenty-four patients had been treated during the study period, and in 116 patients (93.5%) complete follow-up evaluation was available. The overall adjusted incidence of initial traumatic shoulder dislocations was 8.2/100,000 person-years; of all traumatic shoulder dislocations, the rate was at least 11.2/100,000 person-years. Incidence rates were significantly greater for men than for women. There was no urban versus rural difference in incidence or recurrence rates. The authors concluded that shoulder dislocation occurs most frequently in younger male patients and occurs with similar frequency in urban and rural settings. Except for age-related differences in recurrence rates no significant referral bias was found among patients treated at a tertiary care facility as compared with patients from the local community.

Traumatic anterior shoulder dislocation in adolescents.

BACKGROUND: Recurrent instability is the most common complication after traumatic anterior shoulder dislocation in young patients. HYPOTHESIS: The rate of recurrent instability in a homogeneous population of adolescents after initial traumatic anterior shoulder dislocation is significant and is associated with a guarded prognosis for full recovery. STUDY DESIGN: Retrospective cohort study. METHODS: We identified 32 patients 11 to 18 years of age treated at our institution for a radiographically documented traumatic anterior shoulder dislocation; we performed a functional outcome assessment on 30 patients with use of two standard scoring systems. RESULTS: Overall, instability recurred in 24 of 32 patients, with 23 experiencing at least one recurrent dislocation. Persistent instability led 16 of 32 to undergo a shoulder stabilization procedure. There were no significant differences in the functional outcome of patients who had undergone surgical stabilization and those who were treated nonoperatively. CONCLUSIONS: The recurrence rate of shoulder instability was 75%. Outcome scores were similar for patients treated with a surgical procedure and those treated nonoperatively. CLINICAL SIGNIFICANCE: Treatment efforts must be aimed at optimizing shoulder strength and stability. Prognosis for full recovery remains guarded. Available outcome instruments may not discriminate well between patients who do and do not choose surgery.

Sports-related shoulder dislocations: a state-hospital experience.

This retrospective study was conducted in a state hospital set-up and aimed at identifying the incidence of sports-related shoulder dislocations and their characteristics and the sports events involved. All patients with shoulder dislocation related to sporting activities admitted to the hospital from January 1999 to December 2002 were included in the study. There were 18 sports-related shoulder dislocations out of 106 all shoulder dislocations admitted during this 4-year period. The average age of the patients was 25.4 years. All but two were male. All were anterior dislocations. Recurrent dislocation constitutes 78% of the cases with an average of 3 times re-dislocation. Rugby and badminton were the major contributors to the injuries followed by volleyball, soccer and swimming. Conservative treatment was successfully instituted for 88% of the patients and 12% opted for surgical intervention.

Comparative study of intra-articular lidocaine and intravenous meperidine/diazepam for shoulder dislocations.

The purpose of this study was to compare the analgesic effectiveness of intra-articular lidocaine versus intravenous meperidine and diazepam during the reduction of anterior shoulder dislocations. Patients were randomized to one of the two methods before the reduction of shoulder dislocations. Patients marked a visual analog pain scale at baseline, after anesthesia just before reduction, and at the time of discharge. Interference with the procedure caused by pain or lack of muscle relaxation, perception of adequacy of analgesia by the patient, adverse effects, and time to discharge from the Emergency Department (ED) were measured. Differences of outcomes, relative risks (RR), and 95% confidence intervals (CIs) were derived. Fifty-four patients with anterior shoulder dislocations presenting from May 21, 1998 through January 21, 1999 were included in this study; 29 were randomly assigned to receive intra-articular lidocaine (IAL) and 25 to receive intravenous meperidine/diazepam (IVMD). IAL was less effective than IVMD in relieving pre-reduction pain (p = 0.045) but equally effective in overall pain relief (p = 0.98). IAL was more effective than IVMD in shortening recovery time (p = 0.025). There was an indication favoring IVMD in terms of physician-perceived muscle relaxation and patient's perception of analgesia adequacy. In conclusion, although the IVMD method appears to have some clinically and statistically significant advantages, IAL possesses some favorable features that render it to be an analgesia alternative in shoulder dislocation reduction.

Decreasing the incidence of recurrence of first time anterior shoulder dislocations with rehabilitation.

Studies of adolescent and young adult males sustaining primary anterior shoulder dislocations reveal the likelihood of recurrence to be virtually always above 50% and as high as 79% to 94%. Common among these investigations is the lack of a specific, rigidly adhered to rehabilitation program. During a 3 1/2 year period, 20 midshipmen at the United States Naval Academy sustained primary anterior shoulder dislocations. All participated in an identical treatment regimen which included a restrengthening program emphasizing the muscles of internal rotation and adduction, plus rigid restrictions of activities until the goals of their rehabilitation program were satisfied. Exercises progressed from isometrics through isotonics and isokinetics. Goals included return to full active, unrestricted duty and athletic participation which included participation in the sport that resulted in the original dislocation. Patients were followed for an average of 35.8 months (with a range of 17 to 45 months). During the period of study there were five recurrences (25%). A success rate of 75% would suggest that adherence to a specific, aggressive postdislocation rehabilitation program, plus rigid restrictions of activities until the goals of the program are satisfied, can substantially improve the likelihood of a full return to activity without recurrent shoulder dislocation.

Propofol versus midazolam/fentanyl for reduction of anterior shoulder dislocation.

OBJECTIVE: The authors aimed to compare propofol and midazolam/fentanyl for reduction of anterior shoulder dislocations using the modified Kocher's maneuver. METHODS: This was a multicenter, randomized, clinical trial of patients with anterior shoulder dislocation. Patients were randomized to either propofol or midazolam/fentanyl. The randomized drug was titrated to a clinical sedation end point (spontaneous eye closure). One physician sedated the patient. Another, blinded to the drug administered, reduced the shoulder and recorded details of muscle tone and ease of reduction. RESULTS: Eighty-six patients were randomized to treatment with propofol (n = 48) or midazolam/fentanyl (n = 38). Patients in the propofol group had shorter mean times to first wakening (difference in means, 4.6 minutes; 95% confidence interval [CI] = 0.7 to 8.6; p = 0.097) and full consciousness (difference in means, 21.7 minutes; 95% CI = 14.7 to 28.7; p <0.001), had easier shoulder reduction (difference in mean rating, 0.5; 95% CI = 0.0 to 0.9; p = 0.047), and needed fewer reduction attempts (difference in means, 0.5; 95% CI = 0.1 to 1.0; p = 0.02). Patients in the propofol group also had less mean muscle tone at the first reduction attempt (p = 0.08) and needed fewer reduction maneuvers (p = 0.40) but had more respiratory depression (11 vs. six patients; difference in proportions, 7.1%; 95% CI = -11.8 to 26.1; p = 0.58) and had one patient who vomited. CONCLUSIONS: Propofol appears to be as effective as midazolam/fentanyl for reduction of anterior shoulder dislocation using the modified Kocher's maneuver. However, the advantage of shorter wakening times associated with propofol should be weighed against the possibility of adverse events, particularly respiratory depression and vomiting.

Anterior shoulder dislocation with axillary artery and nerve injury.

We report a rare case of left axillary artery injury associated with anterior dislocation of the left shoulder in a 25 yrs old male as a result of a road traffic accident. The shoulder dislocation was reduced. A left upper limb angiogram showed an obstructed left axillary artery. The obstructed segment was surgically reconstructed with a Dacron graft. Six months post operation in follow up, he was found to have good left shoulder function and no neurovascular deficit. This is an injury that could have been easily missed without a simple clinical examination.

Painless reduction of acute anterior shoulder dislocations without anesthesia.

In 1938, Dr Henry Milch described a maneuver for the reduction of acute anterior shoulder dislocations consisting of shoulder abduction and external rotation with "pulsion" of the humeral head. Although many methods may be used to reduce the dislocated glenohumeral joint, the Milch technique is unique because of its gentle, effective, and relatively painless nature. This article studied the effectiveness of this technique on 76 consecutive acute anterior shoulder dislocations in 75 patients seen in our institution's two campuses over an 18-month period. Twelve shoulders had concomitant fractures of the greater tuberosity. All 76 shoulders were reduced on the first attempt. No anesthesia was used, and no complications were reported from the reduction maneuver. The Milch method is an ideal first line treatment for all acute anterior shoulder dislocations including those associated with fracture of the greater tuberosity.

Recurrent shoulder dislocation and screw failure after the Bristow-Latarjet procedure. A case report.

A 22-year-old male was operated on with coracoid transfer according to the Bristow-Latarjet procedure because of recurrent anterior dislocation of his right shoulder. Nine months later the patient sustained a repeat shoulder dislocation after moderate trauma. The screw was radiographically found to be bent. Subscapularis shortening according to Putti-Platt was performed. No repeated episodes of dislocation and no instability has been experienced by the patient since then. However, one year later, he awoke with pain dorsal to the humeroscapular joint. Radiographs showed the screw to be broken. The proximal part of the screw was located underneath the humeroscapular joint and was removed. After this, the patient was free of pain and returned to work as a carpenter.
