Epidemiology of Paediatric Shoulder Dislocation: A Nationwide Study in Italy from 2001 to 2014

Median Nerve Palsy after Shoulder Dislocation in a 10-year-old Girl: A Case Report

Introduction

Traumatic glenohumeral dislocation is very rare in skeletally immature patients, and there are no reports in the literature describing the risk of associated nerve injuries. In the general population, the most commonly affected nerve is the axillary, but anatomical variations with a common origin between the musculocutaneous and median nerves exist that alter the respective positions and courses of these nerves and can make them more prone to injury during a glenohumeral dislocation.

Case Report

A 10-year-old girl presented with incomplete median nerve palsy without any recuperation 8 months after an anterior glenohumeral dislocation. Surgical exploration was performed and revealed a common origin of the musculocutaneus and median nerve, with bifurcation just distal to the glenohumeral joint, making it susceptible to compression-elongation trauma during dislocation. A careful neurolysis was performed, and there was a complete recovery of median nerve function.

Conclusion

Glenohumeral dislocation associated with nerve injury is very rare in children. When a nerve injury occurs, one should be aware of possible anatomical variations of the infraclavicular plexus.

Current Evidence Regarding Shoulder Instability in the Paediatric and Adolescent Population

Paediatric and adolescent shoulder instability is caused by a unique combination of traumatic factors, ligamentous laxity, and pattern of muscle contractility. The multifactorial nature of its aetiology makes interpretation of the literature difficult as nomenclature is also highly variable. The purpose of this review is to summarize the existing literature and shed light on the nuances of paediatric and adolescent shoulder instability. The epidemiology, clinical features, imaging, and management of all forms of paediatric shoulder instability are presented. The main findings of this review are that structural abnormalities following a dislocation are uncommon in pre-pubertal paediatric patients. Young post-pubertal adolescents are at the highest risk of failure of non-operative management in the setting of traumatic instability with structural abnormality, and early stabilisation should be considered for these patients. Remplissage and the Latarjet procedure are safe treatment options for adolescents at high risk of recurrence, but the side-effect profile should be carefully considered. Patients who suffer from instability due to generalized ligamentous laxity benefit from a structured, long-term physiotherapy regimen, with surgery in the form of arthroscopic plication as a viable last resort. Those who suffer from a predominantly muscle patterning pathology do not benefit from surgery and require focus on regaining neuromuscular control.

Post-operative rehabilitation following traumatic anterior shoulder dislocation: A systematic scoping review

Background

This systematic scoping review aimed to describe the content of post-operative rehabilitation programmes, and outcome measures selection following stabilisation surgery for traumatic anterior shoulder dislocation (TASD).

Methods

An electronic search of Medline, EMBASE, CINAHL and AMED was conducted (2000-2021). Any cohort or clinical trial of patients receiving post-operative TASD rehabilitation were included. Study selection, data extraction and quality appraisal were undertaken by two independent reviewers.

Results

Twelve studies including fourteen treatment programmes were eligible. Period of post-operative immobilisation ranged from 1 day to 6 weeks, with exercise introduced between 1 and 7 weeks. Strengthening exercises were introduced between 1 and 12 weeks. Two studies described "accelerated" rehabilitation programmes, differing in immobilisation period and exercise milestones. No increased recurrence was reported in professional footballers. Two studies compared rehabilitation programmes, one not randomised, the other 18 years old. There was variability in selected outcomes measures, with only 4 studies using a common measure.

Discussion

There is minimal evidence to guide post-operative rehabilitation, variability in immobilisation periods and when exercise is introduced. There is no consensus on the definition of accelerated rehabilitation, or outcome measure selection. Clinical consensus of standardised terminology and stages of rehabilitation is required prior to efficacy studies.

Epidemiology of shoulder dislocations presenting to United States emergency departments: An updated ten-year study

BACKGROUND

Glenohumeral dislocation is a common injury that may predispose patients to chronic pain and instability. However, there is a paucity of current data available regarding the epidemiological trends of this injury.

AIM

To provide an updated, comparative assessment of the epidemiology of shoulder dislocations presenting to emergency departments in the United States. We also sought to analyze patient demographic risk factors and consumer products associated with dislocation events.

METHODS

Data were obtained from the national electronic injury surveillance system database for glenohumeral dislocations between 2012 and 2021. Incidence, age, sex, and injury characteristics were analyzed using weighted population statistics as well as incidence rates and 95% confidence intervals (CI).

RESULTS

In total, an estimated 773039 shoulder dislocations (CI: 640598-905481) presented to emergency rooms across the United States during the study period. The annual incidence rate was 23.96 per 100000 persons and the average patient age at the time of injury was 37.1 years. Significantly more male patients sustained dislocations than female patients (537189, 69.5%, vs 235834, 30.5%, P < 0.001). With regard to associated consumer products, sports and recreation equipment were involved in the highest proportion of incidents (44.31%), followed by home structures and construction materials (21.22%), and home furnishings, fixtures, and accessories (21.21%). Regarding product sub-groups, stairs, ramps, landings, floors was cited in the greatest number of cases (131745).

CONCLUSION

The national annual incidence rate of glenohumeral dislocations throughout the study period was approximately 23.92 per 100000 persons. Male adolescents sustained the highest proportion of dislocations, with a peak incidence in age group 15-20 years, predominantly secondary to participation in sporting and recreational activities. Conversely, women experienced a relatively consistent incidence of dislocation throughout their lifespan. After age 63, the incidence rate of dislocations in females was found to surpass that observed in males.

Dynamic pediatric shoulder instability: Etiology, pathogenesis and treatment

Dynamic shoulder instability in children or adolescents, whose glenohumeral growth plates are still open, is a rare condition with an etiology that is hard to decipher. Atraumatic and recurrent forms are most common, contrary to adults. Disruptions to capsule and ligament maturation, muscle balance or bone growth can lead to glenohumeral instability. The etiology assessment, which needs to be multidisciplinary in atraumatic forms, aims to collect the medical history, analyze the direction of the instability, determine whether it is voluntary or involuntary, and look for a history of trauma, connective tissue abnormality, psychological disorder, neuromuscular pathology or congenital malformation. The initial treatment is conservative. It requires a multidisciplinary team when the shoulder instability is voluntary. Surgical treatment is reserved for symptomatic forms that do not respond to conservative treatment and have an impact on daily life and/or sports participation after a minimum of 6 months of well-conducted rehabilitation. The results of surgical stabilization mainly depend on the features of the instability, the anatomical structures damaged and the etiology. Episodes of recurrent instability in children/adolescents with open glenohumeral growth plates can fade in adulthood or can get worse with the development of structural damage. Early detection of poor outcomes and suitable treatment will help to limit the occurrence of osteoarthritis in the medium and long term. LEVEL OF EVIDENCE: Expert opinion.

Trends in Hospitalization and Economic Impact of Percutaneous Kyphoplasty in Italy

Vertebral Fractures (VFs) caused by osteoporosis are the most typical reason for performing Percutaneous Kyphoplasty (PK). Globally, VF prevalence is not well described in the literature. In Europe, only Sweden has an accurate record of the incidence of this type of fracture. Moreover, the exact incidence of the PK procedure is not reported. Therefore, the annual patterns and financial burden of PK in Europe is not well known, and it could be may better understood by examining national registers. For surgeons, lawmakers, hospital administrators, and the healthcare system, determining the annual national costs of this treatment is helpful. The National Hospital Discharge Reports (SDOs) submitted to the Italian Ministry of Health during the years covered by this study (2009-2015) were used. A total of 13,113 kyphoplasties were performed in Italy, with a prevalence of 3.6 procedures for every 100,000 Italian inhabitants over 15 years. The average age of patients was 68.28 (±12.9). Females represented the majority of patients undergoing PK procedures (68.6%). The median length of hospital stay was 5.33 days. The prevalence of PK procedures increased from 2009 to 2015, while the average days of hospitalization decreased. Older patients were most at risk in undergoing PK procedures. Reporting the national data on PK in Italy could also help compare the findings across nations. The current study aims to determine the trends of PK hospitalisation and patient features in Italy.

Shoulder Dislocation Incidence and Risk Factors-Rural vs. Urban Populations of Poland

(1) Background: The aim of this study was to analyze the incidence of shoulder dislocation and to estimate non-modifiable risk factors in rural and urban subgroups in Poland. (2) Methods: The study covered the entire Polish population, divided into urban and rural subgroups and observed between 1 January 2014 and 31 December 2014. The study population consisted of Polish patients with a diagnosis of shoulder dislocation (S43.0) in accordance with the International Statistical Classification of Diseases and Related Health Problems (ICD-10). Records were obtained from the public health care provider National Health Found (Narodowy Fundusz Zdrowia, NFZ). Based on these data, we assessed shoulder dislocation incidence and risk rates, stratifying the study sample by sex, age and place of residence (rural or urban) using the Central Statistical Office (GUS) personal territorial code (TERYT). (3) The incidence was 25.97/100,000 person-years in rural areas and 25.62/100,000 person-years in urban areas. We did not find significant differences in the incidence between the two subgroups. The highest incidence (75.12/100,000 person-years) and the highest risk for shoulder dislocation were found among subjects 80+ years old living in urban areas. Furthermore, men in the third decade of their life living in urban areas showed the highest risk (OR = 7.8, 95% CI; 6.44-9.45, p < 0.001). In both subgroups, the likelihood of shoulder dislocation was significantly lower for the female sex and among children ≤9 years old. However, girls living in rural areas presented with a significantly higher likelihood for dislocation compared with their peers living in urban environments. (4) Conclusions: No significant difference in the incidence rate of shoulder dislocation between Polish residents living in rural and urban areas emerged. The highest incidence was observed among female subjects 80+ years old living in urban environments. The highest risk was found among men in the third decade of their life living in urban areas. In addition, girls in the first decade of their life living in rural areas had more shoulder dislocations than girls living in urban environments. Shoulder dislocation is dominant in female subjects aged 70-79 living in rural areas and in females 80+ years old living in urban areas.

Return to play following open Bankart repair in collision athletes aged 18 years or less

HYPOTHESIS

The purpose of this study was to evaluate clinical outcomes, return to play (RTP), and recurrence rates in patients aged 18 years or less who underwent open Bankart repair (OBR) for anterior shoulder instability.

METHODS

A retrospective review of collision athletes under 18 years old who underwent OBR by 2 surgeons between the years 2010 and 2019 was carried out. An OBR using a subscapularis split was performed in all patients. Recurrent instability, rate of RTP, and time to RTP were recorded. The Shoulder Instability Return to Sport after Injury score, Subjective Shoulder Value score, and visual analog scale scores were also evaluated.

RESULTS

The study included 34 male collision athletes with a mean age of 16.5 ± 1.3 years (range, 15-18 years). The mean follow-up for patients was 49.5 ± 30.7 months. A total of 30 patients (88.2%) returned to full sport at a mean time of 5.8 ± 2.2 months, with 27 (90%) managing to return at their preinjury level of participation. The mean Subjective Shoulder Value score for patients at the final follow-up was 86.8 ± 17.5, the mean Shoulder Instability Return to Sport after Injury score was 86.3 ± 22.6, and the mean visual analog scale score was 1.6 ± 1.8. Eight patients (23.5%) re-dislocated their shoulder, with 4 of them requiring a further surgery. Two patients (5.8%) reported having incidents of subluxation that did not require reduction.

CONCLUSION

This study found high rates of patient-reported satisfaction, excellent functional outcomes, and high rates of RTP in the medium term among young collision athletes aged 18 years or less who underwent OBR for anterior shoulder instability. However, there were high rates of recurrence with moderate rates of revision surgical stabilization in the medium term.

Trends in hospitalization for pediatric hip arthroplasty: an epidemiological Nationwide study in Italy from 2001 to 2015

Background

The epidemiology of Pediatric Hip Arthroplasty (PHA) is unclear. Prevalence of PHA in Europe was reported in Scandinavian registries, but data on this procedure are not described in other countries. Therefore, it is challenging to redact a complete and valid epidemiological report on PHA in Europe. Nevertheless, national health statistics for PHA are helpful for an international audience, as different treatments are reported between countries. Moreover, sharing national statistics and correlating those to other countries’ protocols could be helpful to compare outcomes for different procedures internationally. The principal purpose is to evaluate the yearly hospital admission for PHA in Italy.

Methods

Data of this study were collected from the National Hospital Discharge Reports (SDO) reported at the Italian Ministry of Health.

Results

From 2001 to 2015, 770 PHA hospitalizations were performed in Italy, with an incidence of 0.5 procedures for every 100,000 pediatric Italian inhabitants. The average age of patients was 15.2 ± 4.6 years. The mean length of days of hospitalization was 10.9 ± 8.6 days. The majority of patients were male of 15–19 years old age group. A progressive decrease in days of hospitalizations was found during the years of the study.

Conclusions

In Europe, the incidence of hospital admission for PHA is not fully described. There is a lack of consensus on the best type of surgery to perform on young patients. Epidemiological studies are helpful to understand the national variation of a specific surgical procedure and compare them with other countries.

The burden of percutaneous vertebroplasty: an epidemiological nationwide study in Italy from 2009 to 2015

PURPOSE

Percutaneous vertebroplasty (PV) is a minimally invasive technique requiring the injection of polymethylmethacrylate cement into a collapsed or weakened vertebral body to stabilize the fracture. The present study aims to determine the trends in PV procedures over the recent years. The longitudinal analysis of national registers may help to understand the yearly trends and the economic burden of PV. The evaluation of the yearly national costs of this procedure is essential to surgeons, policymaker, hospital administrator and the healthcare system. Moreover, to observe possible variation in the trend of hospitalization between countries, the data of the present study were compared to the US population.

METHODS

Data of this study were collected from the National Hospital Discharge Reports reported at the Italian Ministry of Health regarding the years of this paper (2009-2015). The yearly number of hospital admission for PV, sex, age, days of hospitalization and primary diagnoses in the whole Italian population were calculated.

RESULTS

31,887 vertebroplasties were performed in Italy, with an incidence of 8.8 procedures for every 100,000 inhabitants. Females represented the majority of patients undergoing PV. The median length of hospital stay was 4.15 days. The mean hospital reimbursement was 4,629€ for each PV hospitalization.

CONCLUSION

The burden of vertebral fracture is relevant in the Italian population, and PV constitutes a rapid and effective treatment. Compared to other countries, the costs of PV in Italy are relatively lower; however, it is important to define the incidence of this procedure to understand the economic trend of PV.

Slipped capital femoral epiphysis: an epidemiological Nationwide study in Italy from 2001 to 2015

BACKGROUND

Slipped capital femoral epiphysis (epiphysiolysis of the femoral head, SCFE) is the most common pediatric hip disease in 10-14 years old children. The most used procedure to correct a stable form of SCFE is in situ pinning. Instead, the proper treatment for unstable forms is controversial. The first purpose of this study was to estimate annual admissions for SCFE in Italian patients from 2001 to 2015, basing on the hospitalization reports. The second aim was to assess the difference between regions regarding SCFE procedures. Lastly, a statistical prediction of the volume of SCFE procedures performed in Italy based on data from 2001 to 2015 was performed.

METHODS

Data of this study were collected from the National Hospital Discharge Reports (SDO) reported at the Italian Ministry of Health regarding the years of this paper. The yearly number of hospital admission for SCFE, the percentage of males and females, the average age, days of hospitalization, primary diagnoses and primary procedures in the whole Italian population were calculated using descriptive statistical analyses.

RESULTS

From 2001 to 2015, 4893 hospitalizations for SCFE were recorded in Italy, with a mean incidence of 2.9 (cases/100.000 inhabitants). The majority of patients treated by SCFE were males (70.6%).

CONCLUSION

National health statistics for SCFE are attractive for an international audience, as different approaches to screening are reported between countries. These differences allow comparing outcomes internationally. Moreover, sharing national statistics and correlating those to other countries protocols, could be helpful to compare outcomes for different procedures internationally. However, further studies are required to understand the specific reasons for regional variation for SCFE procedures in Italy.

Developmental Hip Dysplasia: An Epidemiological Nationwide Study in Italy from 2001 to 2016

Developmental Dysplasia of the Hip (DDH) includes a broad spectrum of hip abnormalities. DDH requires early diagnosis and treatment; however, no international consensus on screening protocol and treatment is provided in the literature. Epidemiological studies are helpful to understand the national variation of a specific surgical procedure and compare it with that of other countries. Data provided by different countries could allow researchers to provide international guidelines for DDH screening and treatment. Limited data are reported regarding trends of hospitalization for DDH, and no public database is available. The purpose of this study was to estimate annual admissions for DDH in Italian patients from 2001 to 2016, based on the hospitalization reports. Data of this study were collected from the National Hospital Discharge Reports (SDO) reported at the Italian Ministry of Health. Descriptive statistical analyses were performed. From 2001 to 2016, 3103 hospitalizations for DDH were recorded in Italy, with a mean incidence of 2.33 (per 100,000 young inhabitants). Females of the 0–4 years old group represented the majority of patients hospitalized for DDH.

Pediatric Musculoskeletal Trauma: Upper Limb

Pediatric upper extremity injuries, acute and chronic due to overuse, are commonly encountered in the clinical setting. However, interpretation of imaging studies is often challenging in pediatric patients because of changing postnatal skeletal development and the broad spectrum of pathology that can potentially occur. This article discusses normal skeletal development and the pathomechanics of skeletal injuries in pediatric patients. It also outlines a framework for imaging as it pertains to the pediatric upper extremity, with specific emphasis on acute and chronic injuries to the shoulder, elbow, forearm, and wrist.

Epidemiology of Anterior Cruciate Ligament Reconstruction Surgery in Italy: A 15-Year Nationwide Registry Study

There remains little information on the epidemiology of anterior cruciate ligament reconstruction (ACL-R), therefore, we performed an epidemiological evaluation on the ACL-R procedures performed in Italy from 2001 to 2015 to highlight potential disparities in access to healthcare. The National Hospital Discharge records (SDO) maintained at the Italian Ministry of Health were analyzed from 2001 to 2015; 248,234 ACL-Rs were performed in Italy over the 15-year study period in the adult population (starting from 15 years old), and the incidence rate per year in 100,000 persons ranged from 21.70 to 33.60 over the study period. The overall male/female ratio was 4.54. The length of hospitalization ranged from four days in 2001 to two days in 2015. Italy is historically divided into north, center, and south regions, and more than half of ACL-R surgery was performed in the north (67.2%); 95.2% of ACL-Rs were underwent in public institutions. The predicted model projected a slight growth in the number of ACL-Rs in the next 10 years (2016–2025). The number of ACL-R procedures increased in the adult population from 2001 to 2015. The ACL-R procedures were concentrated in the north of Italy, suggesting that efforts on regionalization of ACL-Rs should turn toward improving quality in hospitals in the south of Italy.
