Electrical injuries are common phenomena in developing countries, due to inadequate safety measures followed during day-to-day electrical repairs. Workplace injuries account for 20% of these. In some severe cases, electrical injuries lead to burns, indirect fracture dislocations, speech impairments, etc. Falls due to electrical injuries leading to secondary complications are very common and, even though not very severe, they do require immediate treatment and adequate rehabilitation. A 53-year-old male suffered a shoulder injury following an electrical shock. The patient also experienced irritation and speech disturbances. Examination revealed a reduced range of shoulder joints and tightness of muscles of the shoulder complex. Physiotherapy intervention included counseling for the patient and his family members, energy conservation methods for ease in daily activities, a rehabilitation protocol, and modified music therapy. Outcome measures used to assess the progression constituted the Shoulder Pain and Disability Index (SPADI), the Tampa Scale for Kinesiophobia (TSK), and the Depression and Anxiety and Stress Scale. Rehabilitation with adjunct therapy is effective in the overall improvement of the patient\'s condition concerning their mental health as well as physical health by early strength training.

BACKGROUND: Surgical treatment of Rockwood grade V AC joint injuries remains varied. We hypothesized that the addition of a second suspensory device between the clavicle and coracoid would yield superior biomechanical results over a single device. We also hypothesized that the addition of an internal brace across the AC joint to a suspensory device would yield superior results over the suspensory device in isolation.
METHODS: A total of 24 cadaveric shoulders were dissected and randomized to four groups with four different constructs implanted: Group A: Single AC TightRope (Arthrex Inc., Naples, FL, USA) Group B: Double AC TightRope Group C: Single Knotless AC TightRope (Arthrex Inc., Naples, FL, USA) Group D: Single Knotless AC TightRope with AC InternalBrace Ligament Augmentation (Arthrex Inc., Naples, FL, USA) These were then loaded in the Robotic arm (SIMVITRO) where 250 cycles of 50N of force in the superior plane was applied. Dynamic creep, displacement, translation and stiffness were assessed.
RESULTS: Testing was successfully completed for all specimens. There were no failures due to fracture or translation of the clavicle greater than 5mm from the starting position. Reduction was maintained with a mean superior displacement of 1.7 mm (± 1.4 mm). The mean peak to peak displacement, superior and posterior translation, dynamic creep and stiffness did not differ significantly between construct groups.
CONCLUSIONS: This study did not demonstrate any significant biomechanical differences between groups in terms of displacement, translation, creep or stiffness.

BACKGROUND: Nocturnal shoulder pain is seen in patients with rotator cuff tears. The purpose of the present study was to determine whether Doppler ultrasound parameters predict the intensity of nocturnal pain in patients with rotator cuff tears.
METHODS: A total of 60 patients with rotator cuff tears were included. Doppler ultrasound parameters (peak systolic velocity in the anterior humeral circumflex artery, Doppler activity in the glenohumeral joint and subacromial space) and clinical parameters were examined. For the presence of nocturnal pain, the clinical parameters were compared with and without nocturnal pain. For the intensity of the nocturnal pain, a multivariate analysis of clinical parameters and nocturnal pain intensity was performed.
RESULTS: In all, 39 patients (65%) reported nocturnal pain, and the mean pain intensity was 47.0 (standard deviation, 26.0) on the visual analogue scale. In nocturnal pain presence analysis, Doppler activity in the subacromial space showed significant associations (p < 0.001). In nocturnal pain intensity analysis, Doppler activity in the subacromial space and diabetes showed significant associations (p < 0.001, p = 0.01, respectively).
CONCLUSIONS: Doppler activity in the subacromial space emerges as an independent factor associated with the presence and intensity of nocturnal pain in patients with rotator cuff tears. Our findings may provide a basis for further exploration and refinement of treatment strategies.

UNASSIGNED: Research indicates that mechanics differ between athletes with and without upper extremity pain; however, it is unclear which modifiable risk factors exist for throwing-related pain in softball athletes.
UNASSIGNED: To determine whether sport specialization, throwing, practice, and strength and conditioning training volumes vary between youth softball athletes with and without upper extremity pain. It was hypothesized that youth softball athletes with upper extremity pain would participate in softball year-round and have greater throwing, practice, and strength and conditioning volumes compared with those without pain.
UNASSIGNED: Cross-sectional study; Level of evidence, 3.
UNASSIGNED: A total of 232 youth softball athletes from travel ball, middle school, and high school leagues were invited to complete a survey to assess pain, sport specialization, throwing, practice, and strength and conditioning training volumes. Participants were classified into upper extremity pain and no pain groups based on their survey answers. The responses were compared between groups using Mann-Whitney U and chi-square tests.
UNASSIGNED: A total of 101 athletes-with a mean ± SD age of 13.3 ± 2.3 years, height of 161 ± 13.4 cm, and weight of 59.8 ± 14.8 kg-completed the survey and were included for analysis. The response rate was 43.53%, with 22 athletes in the upper extremity pain group and 79 athletes in the no pain group. A significant difference was observed between hours devoted per week to off-season softball practice (U, 626.6; Z =-2; P = .045), where those without upper extremity pain spent 4 fewer median hours (6 hours) practicing softball per week in the off-season compared with those with pain (10 hours). Also, a significant difference was found between the number of throws during an in-season game (U, 457; Z, -2.28; P = .022), where those without upper extremity pain reported 21 fewer median throws (70 throws) during an in-season game compared with those with pain (91 throws). Furthermore, 77% of those who reported upper extremity pain continued to play despite their pain. There were no other significant differences between demographic characteristics, specialization, injury history, and primary position, as well as throwing, practice, and strength and conditioning volumes.
UNASSIGNED: Our study demonstrates that youth softball athletes with upper extremity pain had more throws during in-season games and increased hours per week devoted to off-season practice than athletes without upper extremity pain. Our findings support the need for softball stakeholders (eg, coaches, clinicians, parents, and administrators) to engage in further research and recommendations regarding in-season pitch counts and off-season rest.

BACKGROUND: Loss of shoulder range of motion (ROM) is common after surgical management of anterior shoulder instability; however, it remains unclear to what degree this is related to their injury.
OBJECTIVE: The purpose of this study was to compare passive shoulder ROM in patients with ASI to a normal contralateral shoulder.
METHODS: A total of 121 patients undergoing stabilization surgery were prospectively enrolled. Preoperative advanced imaging was used to assess for glenoid bone loss and the presence of off-track Hill-Sachs lesions. Passive ROM was measured in both shoulders while under anaesthesia prior to surgery.
RESULTS: In all directions, there was a significant loss of ROM in shoulders with instability. Regression analysis showed that neither a glenoid bone defect nor greater glenoid bone loss were associated with a loss of ROM in any plane. The presence of a Hill-Sachs lesion was significantly associated with a loss of external rotation, while off-track lesions were associated with a loss of ROM in all planes (p < 0.05).
CONCLUSIONS: Patients with anterior shoulder instability lost motion in all directions, with a profound loss of external rotation. The presence of a glenoid bone defect nor greater bone loss did not reliably predict a loss of range of motion. A Hill-Sachs lesion was predictive of a loss of external rotation, while an off-track lesion was predictive of a loss of range in all directions.

UNASSIGNED: The use of all-suture anchors for rotator cuff repair is increasing. Potential benefits include decreased bone loss and decreased damage to the chondral surface. Minimal evidence exists comparing outcomes among medial-row anchor fixation methods in double-row suture bridge rotator cuff repair.
UNASSIGNED: To compare the clinical outcomes between all-suture and solid medial-row anchors in double-row suture bridge rotator cuff repair.
UNASSIGNED: Case series; Level of evidence, 4.
UNASSIGNED: A total of 352 patients (mean age at surgery, 60.3 years) underwent double-row suture bridge rotator cuff repair at our institution. Patients were separated into 2 groups based on whether they underwent all-suture (n = 280) or solid (n = 72) anchor fixation for the medial row. Outcomes data were collected via an ongoing longitudinal data repository or through telephone calls (minimum follow-up time, 2.0 years; mean follow-up time, 3.0 years). Outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) standardized shoulder assessment form and the visual analog scale (VAS). The same rehabilitation protocol was administered to all patients. The proportions of patients meeting previously published Patient Acceptable Symptom State (PASS) thresholds were calculated for the outcome measures, and outcome scores and the proportions of patients meeting PASS thresholds between groups were compared using linear and logistic regression, respectively.
UNASSIGNED: The groups did not differ in terms of age at surgery, sex distribution, rotator cuff tear size, or number of medial-row anchors used. The solid anchor group had a longer follow-up time compared with the all-suture anchor group (3.6 ± 0.7 vs 2.8 ± 0.8 years, respectively; P < .01). After controlling for follow-up time, the solid and all-suture anchor groups did not differ in ASES scores (89.6 ± 17.8 vs 88.8 ± 16.7, respectively; P = .44) or VAS scores (1.1 ± 2.1 vs 1.2 ± 2.1, respectively; P = .37). Similarly, after controlling for follow-up time, the solid and all-suture anchor groups did not differ in the proportions of patients meeting PASS cutoffs for the ASES (84.7% vs 80.7%, respectively; P = .44) or the VAS (80.6% vs 75.0%, respectively; P = .83).
UNASSIGNED: Double-row suture bridge rotator cuff repair using all-suture anchors for medial-row fixation demonstrated similar excellent clinical outcomes to rotator cuff repair using solid medial-row anchors.

To assess the effects of the eFisioTrack monitoring system on clinical variables in patients with prescribed physiotherapy for shoulder injuries, twenty-four adult patients with shoulder orthopaedic injuries who underwent physical therapy treatment in a hospital setting participated in the study (twelve in the experimental group and twelve as controls). Clinical outcome measures were shoulder function and pain (Constant-Murley Score and Disabilities of the Arm, Shoulder, and Hand or DASH score). Each variable was measured by a blinded physiotherapist at baseline and at one month follow-up. Patients performed the prescribed exercises either supervised by the physiotherapist (control group) or in a separate room without therapist supervision (experimental group). There were no statistically significant differences between groups before treatment or at follow-up for any outcomes (p ≥ 0.05). There was a statistically significant decrease (p ≤ 0.05) of at least 10 points in both groups for the DASH score at follow-up. Differences in the total score and subjective components of the Constant-Murley were also evidenced within groups. The use of the eFisioTrack system showed similar results in clinical measures compared to those performed under the direct supervision of the physiotherapist. This approach might be suitable for providing an effective shoulder exercise program at home.

OBJECTIVE: To assess whether 5 mL would not be less effective than 10 mL when performing a suprascapular nerve block, regarding shoulder function and quality of life in primary adhesive capsulitis.
METHODS: This is a pilot study of a randomized, controlled, double-blind clinical trial conducted at a single center. Patients with AC characterized by constant pain and restricted movements in anterior elevation, 0°/90° external rotation, and internal rotation were selected. Two groups were randomly selected. In group I, a dose of 10 mL of bupivacaine was applied, while in group II, only 5 mL, in four weekly blocks. Sealed and sequentially numbered envelopes were used. The SF-36 and DASH questionnaires were applied in five moments. The t-Student test was used to compare the means, with a probability of rejecting null hypothesis of 5%.
RESULTS: There were 17 participants with primary AC, seven in group I and 10 in group II. The average age was 54.30 and 50.43 years in the 5 mL and 10 mL groups, respectively. There were no differences when the means were compared by DASH: T0 (p = 0.074); T2 (p = 0.285); T4 (p = 0.333); T8 (p = 0.392), and T12 (p = 0.453). As for the SF-36, there were sparse differences in T2 in the domains of vitality (p = 0.006) and social aspects (p = 0.036) in favor of group I, and in the general health status domain in T8, in favor of group II (p = 0.033).
CONCLUSIONS: The volume of 5 mL is not less effective than 10 mL when performing SSNB in the treatment of primary adhesive capsulitis.

Chronic epilepsy may cause important bipolar bony lesions. We aim to compare the specific pathoanatomic metrics of the bony lesions in chronic shoulder anterior instability that occur in the epileptic population vs non-epileptic population.
METHODS: From 2006 to 2020, we included epileptic and non-epileptic patients with anterior recurrent shoulder instability. We randomly adjusted the patients of the two groups according to the sex, age and type of management. We included 50 patients. For each included patient, we performed an in-depth CT-scan analysis and comparison of the glenoid bone loss: PICO method using the best-fit circle; and the Hill-Sachs lesion: the depth and width were given as a percentage of the humeral head diameter on an axial view. We also evaluated the engaging character of the involved lesion using the On-track/Off-track analysis. Those characteristics were compared between the two groups.
RESULTS: We found a glenoid bone loss in 32 patients. Glenoid bone loss was not significantly greater in patients with epilepsy (p=0.052). A Hill-Sachs lesion was found in 42 patients (22 in epileptic group and 20 in non-epileptic group). Hill-Sachs lesions were significantly deeper and larger in the epileptic group. (depth: 22% vs 9%, p<0.001; width: 43% vs 28%, p=0.003). In the epileptic group 90% of the bone lesions were OFF-track versus 30% in the non-epileptic group. Thus, the epileptic patients presented more engaging bony lesions than non-epileptic patients (p=0.001) (OR=23).
CONCLUSIONS: In a population of epileptic patients, Hill-Sachs lesions are larger and deeper than in patients with non- epileptic shoulder instability. By contrast, there is no significant difference regarding the characteristics of the glenoid bone loss if present. This implies that bone lesions in instable shoulders of epileptic patients need at least a bony stabilization procedure on the humeral side in the majority of cases.

OBJECTIVE: To provide a video tutorial on ultrasound-guided arthrocentesis and injection of the canine hip and shoulder joints.
METHODS: Dogs undergoing arthrocentesis or intra-articular injection for diagnostic or therapeutic purposes.
METHODS: The target joint is visualized in long axis with a 70% isopropyl alcohol medium and linear array probe with a frequency range of 2 to 14 MHz and footprint of 50 mm after clipping a window and preparing the region sterilely. The needle is inserted, bevel up, in long axis with the probe angled at the appropriate trajectory to enter the joint space. The needle is advanced until the tip is visualized entering the joint. Aspiration to obtain synovial fluid can further confirm needle placement or provide diagnostic sampling prior to injection. The aspirate syringe is exchanged for that containing the therapeutic agent, and injectate can then be visualized entering and/or expanding the joint upon injection.
RESULTS: Ultrasound-guided arthrocentesis will help identify deep appendicular joints (hip and shoulder), avoid surrounding vasculature, confirm needle placement, and target joint fluid pocketing. Needle guidance into a joint can reduce iatrogenic tissue damage from inappropriate needle placement and/or by minimizing attempts.
CONCLUSIONS: For arthrocentesis, ultrasound guidance can maximize joint fluid volume acquisition for diagnostic purposes (cytology, culture, and fluid analysis) while also avoiding blood contamination. For joint injections, ultrasound will help ensure real-time intra-articular delivery of the injectate (regardless of attaining synovial fluid feedback) to maximize the therapeutic effect. For either purpose, iatrogenic tissue damage and procedure time are minimized.
