Assessment of rotator cuff tears among bodybuilders in Lahore

Background: The current was performed on bodybuilders to see the shoulder rotator cuff injuries among them. A bodybuilder is a person who strengthens and enlarges the muscles of their body through strenuous exercise. The chances of injury in shoulder is much more than any other region of body because of excessive workout of upper body shoulder and chest than lower region. Objective: To determine the Assessment of rotator cuff tears among bodybuilders in Lahore. Methodology: It was the cross-sectional study. Data was collected by 161 bodybuilders on basis of inclusion and exclusion criteria. Convenient sampling technique was used in this study. Oxford shoulder score questionnaire along with manual physical testing for assessing the rotator cuff injury was used in this study. Data was analyzed by using SPSS. Results: In current study the mean age of respondents was 30.12 with SD 5.85. Minimum age was 20 and maximum age was 45 years.72.6% of the bodybuilders had right side dominant and 27.3 had left side dominant. 22.98% had 1-3 years of experience, 49.68 had 4-6 years of experience and 27.3 had 7-10 years of experience.31.67 had discomfort in their right shoulder and 58.3% had discomfort in left shoulder and 9.93 % had discomfort in both shoulders. 18.51% of the bodybuilders had positive lift of test for subscapularis injury, 40.71 positive drop arm test for supraspinatus and infraspinatus injury, 9.87% had positive horn blower test for teres minor and 30.86% of the bodybuilder had all the rotator cuff tests were negative its mean the other type of shoulder injury rather than rotator cuff. Conclusion: From current study, it was concluded that rotator cuff injury was the commonest injury among all the shoulder injuries. Among the rotator cuff the supraspinatus and infraspinatus was the commonest injured muscle. There should be proper trainer for muscle building so that injury can be prevented. As there was much high prevalence of rotator cuff injury was found in current study. Clinicians and strength and conditioning professionals should consider the biomechanical stresses and adaptations associated with weight training when prescribing upper extremity exercises.

Reporting of Patient-Reported Outcome Measures in Randomized Controlled Trials on Shoulder Rotator Cuff Injuries Is Suboptimal and Requires Standardization

PurposeTo evaluate the completeness of patient-reported outcomes (PROs) reporting using Consolidated Standards of Reporting Trials Patient-Reported Outcome (CONSORT-PRO) in randomized controlled trials (RCTs) involving rotator cuff injuries.MethodsWe performed a comprehensive search of MEDLINE, Embase, and Cochrane Central Register of Controlled Trials for published RCTs focused on rotator cuff injuries that included at least one PRO measure. We included RCTs published from 2006 to 2020. Investigators extracted data from RCTs using the CONSORT-PRO and evaluated each RCT using the Cochrane Risk of Bias 2.0 tool. Our primary objective was to evaluate the mean completion percentage of CONSORT-PRO. Our secondary objective used bivariate regression analyses to explore the relationship between trial characteristics and completeness of reporting.ResultsThe initial search returned 467 results, with 33 published RCTs meeting the prespecified inclusion criteria. The mean CONSORT-PRO completeness across all included RCTs was 49.7% (standard deviation 15.43). An increase in sample size was associated with an increase in mean completeness of reporting (t = 2.31; P = .028). The Risk of Bias assessment found 29 (of 33, 87.88%) RCTs had “some concerns” for bias. We did not find any additional significant associations between completeness of reporting and trial characteristics.ConclusionsRandomized controlled trials involving rotator cuff injuries frequently use PRO measures as primary outcomes. Reporting of these PRO measures is suboptimal and may benefit from rigorous standardization.Clinical RelevancePRO measures are increasingly incorporated as primary or secondary outcomes of RCTs. Appropriate reporting and use of state-of-the-art PRO measures may improve the dissemination of clinical knowledge from RCTs to guide treatment and determine intervention effectiveness. With increased adoption of Patient-Reported Outcome Measure Information System and adherence to CONSORT-PRO, orthopaedic literature may improve PRO reporting to optimize the interpretability of PROs and facilitate patient-centered care.

Effect of systemic administration of recombinant growth hormone on rotator cuff repair a rat model study

Shoulder rotator cuff injuries are prevalent among the elderly. Rotator cuff tears, like osteoarthritis, are an inevitable aspect of aging. The only difference is that soft tissue rather than cartilage is involved in the degenerative process.We hypothesized that exogenous systemic administration of recombinant growth hormone would increase the concentration of various growth factors involved in rotator cuff healing,Forty-eight Sprague-Dawley rats (Charles River, male, 400-450 g) were subjected to unilateral detachment repair of the supraspinatus and infraspinatus tendons at Konkuk University per Institutional Animal Care Committee recommendations.The rats were divided in two groups one were injected with recombinant GH and controls. Initially an artificial rotator cuff tear was created and later repaired with vicryl 4-0. The animals were sacrificed at 1, 3, 6, and 12 weeks. The rotator cuff was removed enmasse. Both groups were compared histologically and immunologically for collagen 1 and 3. Statistical analysis between both the groups was done using SPSS software.The recombinant GH helped in early healing of rotator cuff tears if injected systemically. More clinical trials need to be done before the exact dose can be determined for humans.

Prevalence of sport injuries in Olympic combat sports: a cross-sectional study examining one Olympic period.

Due to full contact impacts in combat sports, the risk of injuries is elevated. The aim of this study is to report severe injuries among athletes in Olympic combat sports. Specific injury types, time loss, and the performance level after injury are examined. Survey to investigate injuries in Olympic combat sports during the time period from 2012-2016. Reported injuries were analyzed by anatomical location, injury type, gender, time loss, and performance level. The three injuries resulting in the longest time loss (ACL rupture: judo= 37 weeks; karate = 49 weeks; shoulder dislocation: wrestling = 41 weeks; shoulder rotator cuff injury: wrestling = 32 weeks) also accounted for the largest proportion of athletes with career-ending injuries (ACL rupture: judo = 28%; karate = 67%; shoulder dislocation: wrestling = 40%; shoulder rotator cuff injury: wrestling = 50%). Taekwondo and fencing had the shortest time loss (<12 weeks) among all combat sports. More injuries occurred during training (58%) as compared to competition (42%). Injury prevalence of competitive athletes was significantly higher as compared to recreational athletes. Male athletes suffered significantly more anterior cruciate ligament injuries (72% vs. 56%; P<0.05), unspecific shoulder injuries (89% vs. 47%; P<0.01), and elbow ligament injuries (57% vs. 30%; P<0.05) during training. The study shows that there are important differences between "punching and kicking" and "throwing" martial arts in terms of specific injury types. In judo and wrestling, the injuries are more likely to affect the joints (knee and shoulder). Therefore, injury prevention these sports should focus on strength training of the muscles surrounding the joints and on defensive reactionary movements to avoid dangerous biomechanical joint angles. In "punching and kicking" sports, injuries of the hands and feet, due to the large impact forces of strikes and kicks, could be reduced by improved protective equipment on hands and feet.

Latissimus dorsi tendon transposition combined with shoulder joint proximal capsule plasty with peroneal longus tendon autograft in the treatment of patients with massive rotator cuff ruptures and proximal dislocation of the humerus head (clinical case)

The frequency of rotator cuff injuries in people over 45 years of age is 25.6–50 %, and 40 % of these injuries are massive. Shoulder rotator cuff injury causes disorders in biomechanics of the shoulder joint such as anterior-superior dislocation of the humeral head. Injury of the deltoid muscle combined with a massive rupture of the rotator cuff causes proximal dislocation of the humeral head during any active movement. In the treatment of these cases, surgical methods of treatment are used, such as transposition of the latissimus dorsi muscle, proximal capsule plasty, and reverse shoulder arthroplasty. We present a successful clinical case of treatment of a patient with chronic massive injury of the right shoulder joint rotator cuff tendons in combination with the injury of shoulder joint proximal capsule, dislocation of the right humerus head, and hypotrophy of the anterior portion of the deltoid muscle. We performed transposition of the latissimus dorsi tendon in combination with shoulder joint proximal capsule plasty with an autograft of the peroneal longus tendon. The check-up X-rays show that the dislocation of the right shoulder joint was eliminated. In the early postoperative period, the patient started physiotherapy exercises of the operated limb using abduction pillow. By the 7th day after surgery, the abduction of the operated limb reached 70°. The described surgical technique allows to restore congruence in the shoulder joint and the function of the injured limb in severe multiple injuries of the shoulder joint structures.

Practice Guidelines for Prevention of Musculoskeletal Disorders in Obstetric Sonography

Ergonomics and prevention of musculoskeletal disorders in obstetric sonography is a subject seldom discussed. However, 80% of sonographers describe pain when performing these examinations. The consequences of these disorders can range from impaired quality of life to the complete cessation of professional activity. Some diseases may even require surgical treatments such as carpal tunnel syndrome and shoulder rotator cuff injuries. After joint disorders mainly affecting the upper limbs and neck, deterioration of visual acuity is the second most commonly reported condition. A literature review can identify risk factors, particularly arm abduction greater than 30°, repeated isometric maneuvers without compensatory rest, the level of force applied to the probe, abdominal scanning approaches, examination times longer than 25 minutes, and more than 100 sonographic examinations per month. The ergonomics of the operator's workstation and posture are essential to prevent these disorders. Machine, probe, chair, and examination bed designs are already subject to industrial consensus, but sonographers are responsible for configuring their ideal workstations to preserve their professional and physical potential. Therefore, this article proposes rules of good practice and illustrates recommended positions and those to avoid.
