Acromioclavicular joint cyst in ASA 3-4 patients. Whether and how quickly it recurs after aspiration and steroid injection
We observed the clinical course, in the short-medium term, of patients with voluminous type II acromio-clavicular (AC) joint cyst who underwent aspiration and steroid injection regarded as the only possible treatment to avoid possible skin complications. Four patients (7.4% of cases described in literature) (3F-1M ; mean age 83 years, range : 78-87 years) with a voluminous ( > 7 cm) oval, no mobile, no fluctuant cyst overlying the AC joint, were retrospectively observed. The patients, judged by the anesthesiologist as ASA 3-4 patients, were merely submitted to cyst aspiration and steroid injection. The content of the cyst was microscopically analysed. All patients were clinically evaluated on the day of aspiration and after 14-30 days and after 1 year. Shoulder function and pain intensity were analysed with Constant score and VAS. We were able to aspirate 80-150 ml of amorphous joint fluid. At the first follow-up, all patients had a recurrence of the cyst, a lower grade of tension of the skin overlying the cyst and also a very little decreasing of pain intensity. After a month from aspiration, the cysts of the 4 patients had the same size as that present before aspiration. The range of motion, the average value of VAS and Constant were similar to those recorded before aspiration. In no case signs of infection or draining sinus occurred. Aspiration is a useless practice. However it is still a motive for discussion if the reduced suffering of the skin overlying the cyst after the aspiration has avoided, or simply postponed, an imminent complication
Association between alcohol consumption and rotator cuff tear
Background and purpose - Long-term alcohol intake is associated with various negative effects on capillary microcirculation and tissue perfusion. We hypothesized that alcohol consumption might be a risk factor for both the occurrence and the severity of rotator cuff tears (RCTs). Patients and methods - A case-control study was performed. We studied 249 consecutive patients (139 men and 110 women; mean age 64 (54-78) years) who underwent arthroscopic rotator cuff repair. Tear size was determined intraoperatively. The control group had 356 subjects (186 men and 170 women; mean age 66 (58-82) years) with no RCT. All participants were questioned about their alcohol intake. Participants were divided into: (1) non-drinkers if they consumed less than 0.01 g of ethanol per day, and (2) moderate drinkers and (3) excessive drinkers if women (men) consumed > 24 g (36 g) per day for at least 2 years. Results - Total alcohol consumption, wine consumption, and duration of alcohol intake were higher in both men and women with RCT than in both men and women in the control group. Excessive alcohol consumption was found to be a risk factor for the occurrence of RCT in both sexes (men: OR = 1.7, 95% CI: 1.2-3.9; women: OR = 1.9, 95% CI: 0.94-4.1). Massive tears were associated with a higher intake of alcohol (especially wine) than smaller lesions. Interpretation - Long-term alcohol intake is a significant risk factor for the occurrence and severity of rotator cuff tear in both sexes
The effects of rotator cuff tear on shoulder proprioception
Purpose: To evaluate the effects of rotator cuff tear (RCT) and its severity on shoulder proprioception. Methods: We studied 132 consecutive patients (67 M-65 F; mean age ± SD, 66.03 ± 9.04; range, 43–78) who underwent arthroscopic rotator cuff repair. Tear size was determined intra-operatively. The control group included 82 subjects (38 M-44 F; mean age ± SD, 65.87 ± 8.06; range, 41–75) with no RCT. All participants, wearing an eye mask, were submitted to the evaluation of the joint position sense (JPS) at 30°, 60°, 90°, 120°, and 150° of shoulder forward flexion during the sitting position, using a digital inclinometer securely attached to the subject’s arm using hook-and-loop straps. The passive placement and active replacement method was used; the order of the tested angles was randomly selected. The entire test was repeated three times. The error score, by averaging the three trials, was measured as the absolute difference between the target angle and the observed angle. Statistics were performed. Results: The intraclass correlation coefficient for all degrees of flexion movement measured was > 0.90, exhibiting a very high correlation. We found significant differences between cases and controls regarding the results of joint position sense error at all measurements (p < 0.05). According to RCT size, we found significant differences between groups at 30° (F = 27.27, p < 0.001), 90° (F = 5.37, p = 0.006), 120° (F = 10.76, p < 0.001), and 150° (F = 30.93, p < 0.001) of shoulder flexion; in details, patients with massive RCT showed greater absolute error value than those with both small and large RCT at 30°, 90°, 120°, and 150° of shoulder flexion (p < 0.05). Conclusions: RCT provokes an alteration of shoulder proprioception, evaluated as the loss of joint position sense, and the impairment is related to tear severity
Early Minimally Invasive Percutaneous Fixation of Displaced Intra-Articular Calcaneal Fractures With a Percutaneous Angle Stable Device.
The Minimally Invasive Reduction and Osteosynthesis System(®) (MIROS) is a percutaneous angle stable device for the treatment of fractures. The aim of the present study was to evaluate the clinical and radiographic results of an early minimally invasive osteosynthesis with the MIROS device. A total of 40 consecutive patients were treated for an intra-articular fracture of the calcaneus. We evaluated the clinical and radiographic outcomes after treatment of intra-articular calcaneal fractures with the MIROS hardware. Soft tissue damage was noted. The patients completed the American Orthopaedic Foot and Ankle Society survey at 12 and 24 months and underwent radiologic evaluations. A statistically significant association between the American Orthopaedic Foot and Ankle Society score and type of soft tissue lesion. A Sanders type II, III, and IV fracture was found in 15, 20, and 15 of 50 fractures, respectively. Postoperatively, restoration of the posterior facet was reached in 13 of 15, 18 of 20, and 11 of 15 with a type II, III, and IV fracture, respectively. The American Orthopaedic Foot and Ankle Society scale mean score was 85 at the final follow-up visit. No significant association was found between the score and the preoperative variables (p > .09), although patients with bilateral fractures had a significantly lower score. The MIROS device for early treatment of intra-articular calcaneus fractures resulted in excellent clinic and radiologic results. The standardized technique we have reported, with the elastic wires acting as a girder for the fractured and displace subtalar joint and the collapsed lateral calcaneal wall, has permitted early weightbearing with positive stimuli for the bone healing. The drainage effect of the percutaneous wires likely prevented compartment syndrome when applied within the first hours after the trauma.The Minimally Invasive Reduction and Osteosynthesis System® (MIROS) is a percutaneous angle stable device for the treatment of fractures.

The impact of COVID-19 on shoulder and elbow trauma in a skeletally immature population: an Italian survey
Background: The aim of this study was to evaluate the impact of COVID-19 on the shoulder and elbow trauma in a skeletally immature population in 30 days starting from March 8, 2020, the first day of restrictions in Italy, and to compare it with the same period of2019.Materials and methods: All the skeletally immature (younger than 18 years) patients managed in the emergency unit of our hospital between March 8, 2020, and April 8, 2020 (COVID-19 [C19] period), for a shoulder and elbow trauma were retrospectively included and compared with patients with similar ages admitted in the same period of 2019 (no COVID-19 period). Six categories of diagnosis were distinguished: (1) contusions, (2) no physeal fractures, (3) physeal fractures (Salter-Harris), (4) sprains/subluxations, (5) dislocations, and (6) others (tendinitis, wounds, low back pain, and joint inflammation). According to the mechanism of injury, we arbitrarily distinguished 5 subgroups: (1) accidental fall; (2) sport trauma; (3) accident at school; (4) high-energy trauma occurred by car, public transport, and pedestrian investment; and (5) fall from height.Results: During the C19 period, the number of total accesses in our trauma center steeply decreased: two-thirds less. Regardless of the patient age, we performed 65% less first aid shoulder/elbow services. The number of skeletally immature patients treated at our trauma center for all types of injuries was 350 during the no COVID-19 period and 54 during the C19 period; therefore, the influx of pediatric patients during the C19 period decreased by 84.6%. Furthermore, during the C19 period, (1) there were no cases of fractures, physeal fractures, and dislocations of the shoulder; (2) there were no cases of contusion, physeal fractures, and dislocations of the elbow; and (3) we observed the absence of high-energy, sports, and school injuries; and (4) during the pandemic, shoulder and elbow injuries mainly occurred as a result of accidental fall at home.Conclusions: The pandemic forced us to become aware of the ways and places where skeletally immature subjects report shoulder and elbow traumas; therefore, it would be desirable that more considerable attention be directed toward the prevention of injury in areas at risk
THE MORPHOMETRY OF THE CORACOID PROCESS - ITS AETHIOLOGIC ROLE IN THE SUBCORACOID IMPINGEMENT SYNDROME
Abstract: Anatomical morphometric studies of the coracoid process and coraco-glenoid space were carried out on 204 dry scapulae. No statistically significant correlations were found between length, or thickness of the coracoid process, prominence of the coracoid tip, coracoid slope, coraco-glenoid distance, or position of the coracoid tip with respect to the uppermost point of the glenoid. These anatomical characteristics were independent. of the dimensions of the scapulae. Three configurations of the coraco-glenoid space were identified. Type I configuration was found in 45% of scapulae and Type II and Type III, in 34% and 21% of specimens, respectively. The lowest value of the coraco-glenoid distance were seen in Type I scapulae. Morphometric characteristics which might predispose to subcoracoid impingement were found in 4% of Type I scapulae. A total of 27 scapulae, nine with each type of configuration were submitted to CT scanning. Scapulae with a Type I configuration were found to have low values for the coraco-glenoid angle and coracoid overlap, which are known to be associated with a short coraco-humeral distance. Subjects with a Type I configuration, and severe narrowing of the coraco-glenoid space, appear to be predisposed to coraco-humeral impingement. These morphometric characteristics may be easily evaluated on CT scans
Radiographic patterns of osteoporotic proximal humerus fractures
The objectives of the study were: a) to identify osteoporotic proximal humerus fractures in a large consecutive series of patients; b) to identify radiographic fracture patterns among osteoporotic and non-osteoporotic proximal humerus fractures; and c) to calculate intra- and inter-observer reliability of assessment of osteoporosis and of radiographic fracture patterns
Scapular dyskinesis in young, asymptomatic elite swimmers
Background:
Overhead athletes are at a greater risk of developing scapular dyskinesis (SD). Although swimming is considered an overhead sport, information regarding SD in these athletes is scarce.
Purpose:
To determine the prevalence of SD in young, asymptomatic elite swimmers.
Study Design:
Cross-sectional study; Level of evidence, 3.
Methods:
A total of 661 asymptomatic elite swimmers were enrolled in this study (344 male, 317 female; mean age, 15.83 ± 2.20 years). Anthropometric characteristics, training routine, and stroke specialty were recorded. SD was assessed using a dynamic test consisting of an examination of the shoulder blades throughout synchronous forward flexion motion in the sagittal plane and was deemed to be either present or absent. Each movement was repeated 5 times. These evaluations were performed with athletes at rest, before any training or competition. Statistical analysis was performed.
Results:
SD was detected in 56 (8.5%) participants. Type I SD was the most common (46.5%); male participants were 2 times as likely to have SD as female participants (39 male, 17 female; P < .01). No correlation was found between the dominant limb and side affected (P = .258); rather, a correlation was found between the breathing side and side affected, in that swimmers with a preferred breathing side were more prone to develop SD in the opposite shoulder (P < .05). Swimmers involved in long-distance races were found to have a greater risk of developing SD (P = .01).
Conclusion:
SD may be an asymptomatic condition in elite young swimmers and is present in 8.5% of these athletes. Early diagnosis may be useful for asymptomatic athletes with SD and to avoid its possible evolution to a symptomatic condition
RELATIONSHIP BETWEEN OS ACROMIALE AND ACROMIOCLAVICOLAR JOINT ANATOMIC POSITION
Most of the orthopaedic literature on os acromiale is focused on the clinical
implications, such as impingement and rotator cuff tears; although os acromiale
is present in 8% of subjects, scarce information is reported on the causes that
may predispose patients to it. Our aim is to investigate whether the origin of os
acromiale is related to the position of the acromioclavicular (AC) joint. The
acromions of 211 volunteers (control group) and 33 subjects without or with os
acromiale were radiographically (axillary view) classified by the Edelson and
Taitz method. The method distinguishes the acromion into three types on the basis
of the distance between the anterior aspect of the acromion and the AC joint. Of
33 subjects with os acromiale, 11 were without pain. We have compared the
frequency of the three types of acromion observed in the two investigated
cohorts. Half of the acromions of the control group (52.1%) had the articular
facet of the AC joint on the acromion tip, whereas in 45.4% the facet tip was
located distally. On the other hand, of 33 subjects with os acromiale, 18.1% and
81.1%, respectively, had the AC joint lying on or distal to the acromion tip. Our
data suggest that the greater the distance of the AC joint from the anterior edge
of the acromion, the higher the likelihood of an os acromiale
A new test of resistance in the diagnosis of postero-superior rotator cuff tears.
The aim of this study was to assess the diagnostic accuracy of a new clinical test for the diagnosis of subacromial impingement and full thickness postero-superior rotator cuff tears. One hundred and twenty patients who underwent arthroscopic treatment for acromioplasty or cuff repair were previously submitted to a new test of resistance. The test is performed in the standing position with the involved arm in 90 degrees abduction, 20 degrees -30 degrees anteposition and in external rotation (as for full-can test). Thus, the patient was invited to follow the way of a spiral drawn on a drawing sheet for 20 turns; 1 turn = from the centre to the end of the spiral and vice versa (spiral width = 20 cm). The test was considered positive when the patient was not able to conclude it due to strength decrease or to shoulder pain. Sensitivity, specificity, positive and negative predictive values as well as diagnostic accuracy were calculated for our test of resistance. The test resulted scarcely reliable as detector of subacromial impingement and not very reliable as detector of small tear. When the test is positive there is a high probability that a subacromial disease exists; instead, when it is negative there is a high probability that the patient has not a large or massive cuff tear. The resistance test (Gum-Turn test) adds to our armamentarium of physical examination signs in patients with painful shoulder and furnishes further information on possible dimensions of tendinous tear
