The purpose of this study was to record the basic morphometric values of the acromion. Forty-four pairs of dried scapulas were reviewed. Acromial shape was evaluated in relation to sex, symmetry and presence of subacromial enthesophytes and classified according to Bigliani with the following results: type I (flat): 26.1%, type II (curved): 55.6% and type III (hooked): 18.1%. There was a greater percentage of type III in men (56.2% vs. 43.7%) and type I in women (56.5% vs. 43.4%). Acromial morphology was symmetric in 29 acromia (65.9%). Enthesophytes were most common in type III (75%). A rough inferior surface of the acromion was most frequently found in type III (81.2%). Nine other scapular osteological parameters were also measured. Many differences were noted between male and female scapulae. The great variety of morphological features is assumed to be related to rotator cuff pathology and other shoulder impairments.

Background. Recurrent shoulder dislocations occur much more frequently in adolescents than in the older population but a clear explanation of this incidence does not exist. The aim of the present study was to define the age-related distribution of the elastic fibers (EFs) in the shoulder capsule’s extracellular matrix as a factor influencing shoulder instability. Materials and Methods. Biopsy specimens were obtained from the shoulder capsule of patients divided preoperatively into three groups: Group 1 consisted of 10 male patients undergoing surgery for unidirectional traumatic anterior instability (TUBS); Group 2 consisted of 10 male patients undergoing surgery for multidirectional instability (MDI); Group 3 represents the control, including 10 patients with no history of instability. In addition to the group as a whole, specific subgroups were analyzed separately on the basis of the age of subjects: > 22 or < to 22 years. All the samples were analyzed by histochemical (Weig...

The Active Movement Scale is a frequently used outcome measure for children with obstetric brachial plexus palsy (OBPP). Clinicians observe upper limb movements while the child is playing and quantify them on an 8 point scale. This scale has acceptable reliability however it is not known whether it accurately depicts the movements observed. In this study, therapist-rated Active Movement Scale grades were compared with objectively-quantified range of elbow flexion and extension and shoulder abduction and flexion in children with OBPP. These movements were chosen as they primarily assess the C5, C6 and C7 nerve roots, the most frequently involved in OBPP. Objective quantification of elbow and shoulder movements was undertaken by two-dimensional motion analysis, using the v-scope. Young children diagnosed with OBPP were recruited from the Royal Children's Hospital (Melbourne, Australia) Brachial Plexus registry. They participated in one measurement session where an experienced paed...

Subacromial impingement syndrome (SIS) is a prevalent cause of shoulder pain and dysfunction. This study investigates the impact of virtual reality (VR) therapy on shoulder function, joint dysfunction, and pain in SIS patients, comparing its effectiveness to traditional rehabilitation methods. Materials and Methods: Over 50 weeks, 288 participants with SIS were recruited and divided into two groups: an experimental group (EG) receiving VR-augmented therapy and a control group (CG) undergoing conventional rehabilitation. Recovery was assessed using the Painful Arch Test and Simple Shoulder Test (SST) at key intervals (T0, T1, T2, and T3). Statistical analysis was conducted to evaluate recovery times and functional improvements. Results: The EG showed significantly faster recovery with a mean duration of 6.04 weeks compared to 7.01 weeks for the CG (p = 0.0041), as determined by the Welch Two Sample t-test. The 95% confidence interval (0.3137 to 1.6330) confirmed the reliability of these findings. The VR group demonstrated sustained functional improvements, as evidenced by narrower interquartile ranges and more stable SST scores over time, particularly by Session 18, indicating reduced variability and faster recovery compared to the CG. Conclusion: VR therapy significantly accelerates recovery in SIS patients, offering faster and more consistent outcomes compared to conventional rehabilitation. These findings highlight the potential of VR as a non-invasive and effective treatment for improving shoulder function in SIS. Further research is warranted to explore its long-term efficacy and potential for personalized rehabilitation programs.

Introduction Research suggests that current care for shoulder pain is not in line with the best available evidence. This project aims to assess the effectiveness, cost-effectiveness and the implementation of an evidence based guideline for shoulder pain in general practice in Norway. Methods and analysis A stepped-wedge, cluster randomised trial with a hybrid design assessing clinical effectiveness, cost-effectiveness and the effect of the implementation strategy of a guideline-based intervention in general practice. We will recruit at least 36 general practitioners (GPs) and randomise the time of cross-over from treatment as usual to the implemented intervention. The intervention includes an educational outreach visit to the GPs, a computerised decision tool for GPs and a self-management application for patients. We will measure outcomes at patient and GP levels using self report questionnaires, focus group interviews and register based data. The primary outcome measure is the patient reported Shoulder Pain and Disability Index measured at 12 weeks. Secondary outcomes include the EuroQol Quality of Life Measure (EQ5D-5L), direct and indirect costs, patient’s global perceived effect of treatment outcome, Pain Self-Efficacy and Brief Illness Perception Questionnaire. We will evaluate the implementation process with focus on adherence to guideline treatment. We will do a cost–minimisation analysis based on direct and selected indirect costs and a cost–utility analysis based on EQ5D-5L. We will use mixed effect models to analyse primary and secondary outcomes. Ethics and dissemination Ethics approval was granted by the Regional Committee for Medical and Health Research Ethics-South East Norway (ref. no: 2019/104). Trial results will be submitted for publication in a peer reviewed medical journal in accordance with Consolidated Standards of Reporting Trials. Trial registration number NCT04806191

Objectives: To investigate the effectiveness and reliability of 3-Dimensional (3D) printed models of the contralateral, unaffected clavicle to serve as templates of the affected side for preoperative planning. Method: Computed tomography scans of 18 embalmed cadavers (8 male and 10 female) were used to 3D-print mirror images of "unaffected" clavicles which were then used for the selection of a superior midshaft contoured plate. Various morphometric and goodness-of-fit measurements were taken of the 3D-printed clavicle and then the in-situ specimen. Statistical analysis was performed using two-tailed, unpaired t-tests with a p value < 0.05. Results: For 3D-printed models, 7/9 morphometric measurements differed significantly between males and females for both clavicles and in 1 additional measurement for right-sided clavicles. For in-situ specimens, 6/9 morphometric measurements differed significantly between male and female clavicles. When comparing the 3D-printed versus the corresponding in-situ clavicle, only 1/9 morphometric measurements differed significantly for both males and females and 1 additional measurement for each sex. The goodness-of-fit of the plate using the 3D-printed template for the in-situ specimen differed significantly only for males with a right clavicle mirrored to template for the left clavicle. Conclusions: Clavicular anatomic complexity and variance supports the need for many contoured plate options for adequate fixation. Preoperatively 3D-printed contralateral, mirrored clavicles for plate selection of midshaft clavicular fractures may reduce intraoperative time.

Background: Fractures of the elbow, specifically humeral intercondylar
fractures, are common among adults worldwide, and treatment methods for
these fractures vary based on various factors. Precontoured distal humeral
locking plate fixation and humeral reconstruction plate fixation have
gained popularity in the orthopedics community as treatment options. This
study aimed to compare the functional outcomes of humeral intercondylar
fracture treatments between precontoured distal humeral locking plate and
humeral reconstruction plate.

This study analyses, using selected somatometric features, secular trend changes which have occurred over a quarter of a century in female and male students of the Medical University of Łódź. The study is based on the results of an anthropometric survey carried out among first-year students who commenced their studies in the academic years 1978/79 (240 females and 193 males), 1982/83 (347 females and 188 males), 1988/89 (178 females and 165 males) and 2003/04 (188 females and 77 males). The following features were examined in all participants in the survey: body height (B-v), the height of the lower body segment measured from a floor base to the crista iliaca at the point on the mid-axillary line (B-ic), shoulder width (a-a), intertrochanteric distance (tro-tro) and resting chest circumference. To compare average values Student's t-test was used with assumptions of equal and unequal variances. To gauge the magnitude of changes in specific features in the course of a quarter of a century a percentage difference in results was calculated for the years 2003/2004 and 1978/1979. The basis for the calculations was the initial value of a feature at the beginning of the period analysed. It was determined that in the 25-year period analysed (1978-2003) the young people commencing studies at the Medical University of Łódź exhibited an acceleration in the height of the lower body segment (B-ic) and of the intertrochanteric distance (tro-tro) and a deceleration in resting chest circumference. Additionally, an increase in shoulder width has been noted in female students; no significant intergenerational changes were noted in body height, although the last 15 years display certain symptoms of deceleration; there is an emerging tendency towards a blurring of the differences in body proportions between the sexes in the environment of the young people studying at the Medical University of Łódź.

Department of Orthopaedics and Traumatology, State University of Medicine and Pharmacy Nicolae Testemitanu, Chisinau, Moldova, The 6th International Medical Congress for Students and Young Doctors, May 12-14, 2016Introduction: Management of recurrent shoulder dislocation remains to be a challenge for orthopedics. Recurrent shoulder dislocation is present in 16,3% of all joint trauma cases. Maximal frequency is between 20 and 30 years old men (80%) in 90% of cases. Anatomical repair addressing the underlying pathology is the preferred method. In this study we will present the hypothesize that Bristow- Latarjet procedure is effective in most of recurrent shoulder dislocations cases. Materials and methods: A total of 36 patients with recurrent shoulder dislocation were treated with Bristow-Latarjet procedure between 2013 and 2015. The patients were classified by: gender, age, trauma localization (right or left), etiology of first dislocation, place of residence (rural or urban), patien...

The AAO Journal/19 ➻ Introduction J. Gordon Zink, DO1 was the originator of the term Common Compensatory Pattern (CCP). He used the term to describe commonly found patterns of dysfunction in the body (neuromyofascial-skeletal unit2 ) as a whole. Several other physicians3-6 before and since, have also described recurring patterns of dysfunction found in their patient populations. Dr. Zink, however, is considered to be “... the first to provide a written, understandable, and clinically useful explanation for treatment, with a method of diagnosing and manipulative methods of treating the fascial patterns of the body.”7 Zink himself considered these concepts to be the basis of a respiratory and circulatory care model.2 As osteopathic clinicians we frequently find recurrent patterns of fascial bias, postural asymmetry, somatic dysfunction, and functional disturbances. We frequently see a clinically short right leg, a cephalad pubes dysfunction on the left, a posterior ilium on the left a...

Thoracic spine flexibility affects head motion, which is critical to control in motor vehicle crashes given the frequency and severity of head injuries. The objective of this study is to investigate the dynamic response of the human upper thoracic region. An original experimental/analytical approach, Isolated Segment Manipulation (ISM), is introduced to quantify the intact upper thoracic spine-pectoral girdle (UTS-PG) dynamic response of six adult post-mortem human subjects (PMHS). A continuous series of small displacement, frontal perturbations were applied to the human UTS-PG using fifteen combinations of speed and constraint per PMHS. The non-parametric response of the T1-T6 lumped mass segment was obtained using a system identification technique. A parametric mass-damper-spring model was used to fit the non-parametric system response. Mechanical parameters of the upper thoracic spine were determined from the experimental model and analyzed in each speed/constraint configuration....
