Anterior glenohumeral instability is the most frequent type of shoulder instability. This is often associated with labral and osseous lesions leading to recurrent instability. A detailed medical histo...
Traumatic anterior shoulder instability is common in the adolescent athlete, and when it is untreated, the recurrence rate is high. Atypical lesions-such as anterior glenoid periosteal sleeve, humeral...
To evaluate the age, skeletal immaturity, bone loss, and uncommon soft tissue lesions as correlates of posttraumatic anterior shoulder instability lesion patterns in an adolescent population....
Cross-sectional study, Level of evidence, 3....
Consecutive patients ≤18 years of age (160 shoulders) treated within a single institution for traumatic anterior shoulder instability between June 2013 and June 2021 were reviewed. Demographics, injur...
An overall 131 shoulders (mean, 15.3 years; range, 10.5-18.3) were identified for this study: 55 in patients <15 years old and 76 in patients ≥15 years old. Bony injuries such as Bankart and Hill-Sach...
In this series of anterior shoulder instability in children and adolescents, instability lesions varied significantly by age. Bone loss was associated with older age at presentation, and atypical lesi...
Bilateral posterior fracture-dislocation of the shoulder is an uncommon injury pattern usually caused by epileptic seizures. The cause of the seizure activity remains unknown in most cases, although t...
The glenohumeral joint dislocation can be associated with major nerve injury. The reported prevalence and risk factors for major nerve injury are variable and this injury can have a severe and life-lo...
A 1 year retrospective cohort study of 243 consecutive adults who presented with a shoulder dislocation was performed. Data were collected on patient demographics, timings of investigations, treatment...
Of 243 patients with shoulder dislocation, 14 (6%) had neurological deficit. Primary dislocation (p = 0.004) and older age (p = 0.02) were significantly associated with major nerve injury. Sex, time t...
Shoulder dislocation requires careful assessment and timely management in the ED. A 6% rate of nerve injury following shoulder dislocation was at the lower border of reported rates (5-55%), and primar...
The management of first-time traumatic anterior shoulder dislocations has been a topic of extensive study yet remains controversial. Development of a treatment plan requires an understanding of patien...
The risk factors for recurrent instability (RI) following a primary traumatic anterior shoulder dislocation (PTASD) remain unclear. In this study, we aimed to determine the rate of RI in a large cohor...
A total of 1,293 patients with PTASD managed nonoperatively were identified from a trauma database (mean age 23.3 years (15 to 35); 14.3% female). We assessed the prevalence of RI, and used multivaria...
The overall rate of RI at a mean follow-up of 34.4 months (SD 47.0) was 62.8% (n = 812), with 81.0% (n = 658) experiencing their first recurrence within two years of PTASD. The median time for recurre...
This study clarifies the prevalence and risk factors for RI following PTASD in a large, unselected patient cohort. Although these data permitted the development of a predictive tool for RI, its discri...
A prospective randomized comparative group clinical study was conducted, which included 20 patients who in 2019-2021 underwent surgical treatment of chronic posterior dislocation of the shoulder in th...
Both the McLaughlin procedure and the reconstruction of the humeral head using a customized implant made using additive 3D printing technologies increased the range of motion in the shoulder joint, mi...
Customized implants made using additive technologies can shorten the surgery duration by 1.3 times, whereas the volume of intraoperative blood loss - by at least 1.5 times compared to the McLaughlin p...
Acute anterior shoulder dislocation (AASD) is the most common joint dislocation. Here, we introduced a new reduction technique for AASD, named "Han's technique" (or "Touch overhead technique")....
Patients diagnosed with AASD were treated with "Han's technique" in the orthopaedic department of our hospital from October 2018 to November 2020. An orthopedic surgeon performed the reduction maneuve...
Forty-one patients with AASD were involved in our study. Thirty-nine cases (95%) were primary dislocation. Eleven patients (27%) were complicated with large tubercle fracture and one patient (2%) comp...
Han's technique (or Touch overhead technique) is a simple, safe, effective, mild and easy to master which can be operated by one surgeon without anesthesia or sedation for AASD....
To explore the geographical and temporal trends of traumatic shoulder dislocation, describe the association between the social and demographic factors and the health burden due to traumatic shoulder d...
Data on traumatic shoulder dislocation was collected from the Global Burden of Disease 2019, spanning the years 1990 to 2019. The epidemiology and disease burden were examined at global, regional, and...
Over a span of 30 years, both the crude and age-standardized rates of incidence and years lived with disability (YLDs) rates for all genders displayed a slight fluctuating downward trend. The incidenc...
The disease burden of traumatic shoulder dislocation has not significantly decreased from 1990 to 2019. The incidence and YLD rates are associated with age, gender, and SDI. A thorough examination of ...
Recurrent shoulder dislocations can result in kinematic changes of the glenohumeral joint. The number of prior shoulder dislocations may contribute to increased severity of capsulolabral lesions. The ...
Eight fresh-frozen cadaveric shoulders were dissected free of all soft tissues except the glenohumeral capsule. Each joint was mounted in a robotic testing system. At 60 degrees of glenohumeral abduct...
During the 7th, 8th, 9th, and 10th dislocations, the humerus significantly translated superiorly compared with the shoulder during the 1st dislocation (p < 0.05). Following the 3rd, 4th, 5th, and 10th...
Multiple anterior shoulder dislocations lead to abnormal translational kinematics and result in increased superior translation of the humerus. This may contribute to pathologic superior extension of c...
