Lateral elbow tendinopathy, or “tennis elbow,” is a pathology that affects around 1.3% of the general population. Capacitive–resistive electric transfer therapy aims to provoke temperature and current flow changes in superficial and deep tissues. The aim of this in vitro study was to analyze the thermal behavior and transmission of electric current on the superficial and deep tissues of the elbow during the application of different modalities of a capacitive–resistive electric transfer treatment protocol for chronic elbow tendinopathy. A cross-sectional study was designed; five fresh cryopreserved cadavers (10 elbows) were included in this study. A 30 min intervention was performed based on a protocol commonly used in clinics for the treatment of chronic lateral elbow tendinopathy by diathermy using the “T-Plus.” Common extensor tendon, radiohumeral capsule, and superficial temperatures were registered after each application for the duration of the 30 min treatment protocol. During all applications, we observed a current flow of over 0.03 A. The protocol showed a statistically significant increase in superficial temperature by 24% (5.02°) (p < 0.005), the common extensor tendon by 19.7% (4.36°) (p < 0.007), and the radiohumeral joint capsule by 17.5% (3.41°) (p < 0.005) at the end of the 30 min protocol compared with the baseline temperature. The different applications of the protocol showed specific effects on the temperature and current flow in the common extensor tendon and radiohumeral capsule. All applications of the protocol produced a current flow that is associated with the generation of cell proliferation. These results strengthen the hypothesis of cell proliferation and thermal changes in deep and distal structures. More studies are needed to confirm these results.

Background: In a study from our institution, ultrasonic percutaneous tenotomy of the brevis and the common extensor tendon for recalcitrant lateral elbow tendinopathy showed excellent safety profiles, high tolerability, efficiency, sustained pain relief, functional improvement, and sonographic evidence of tissue healing in 20 patients at 3 years’ follow-up. Purpose: To explore the long-term clinical and sonographic results of ultrasonic percutaneous tenotomy of the brevis and the common extensor tendon. Study Design: Case series; Level of evidence, 4. Methods: The same cohort of 20 patients was recalled after 7 years, and visual analog scale (VAS) for pain and Disabilities of the Arm, Shoulder and Hand (DASH) scores, need for secondary intervention, and overall satisfaction were assessed. They were also reassessed using ultrasound imaging of the brevis and the common extensor tendon to evaluate tendon hypervascularity, tendon thickness, and the progress or the recurrence of the hypoechoic scar tissue. Results: We successfully scored 19 patients and performed ultrasound on 16 patients with a median follow-up of 90 months (range, 86-102 months). There were no adverse outcomes and satisfaction remained at 100% (6 patients, satisfied; 13 patients, very satisfied). No patient developed a recurrence of symptoms and signs of lateral elbow tendinopathy, and therefore no secondary intervention was required. The improvement from baseline and early term scores was sustained ( P < .001 for all). At 90 months, there was a significant improvement in VAS scores and DASH–Compulsory scores compared with preprocedure scores and all follow-up times until 3 months. There was no difference in VAS scores and DASH–Compulsory scores at 90 months compared with 6 and 36 months. For DASH–Work scores, there was a significant improvement at 90 months compared with preprocedure scores, but there was no difference between DASH–Work scores at 90 months and scores at all other points of follow-up. At 90 months, hypervascularity remained resolved in 79% of patients, while all patients had reduced tendon swelling and sustained resolution or reduction of the hypoechoic lesion. Conclusion: At the long-term follow-up of 90 months, ultrasonic percutaneous tenotomy of the brevis and the common extensor tendon, previously shown to enhance recovery of lateral elbow tendinopathy, demonstrated good durability of pain relief and functional recovery that was previously achieved. This was accompanied by sustained sonographic tissue healing with no significant deterioration.

Neurovascular Bundles

Because of few anatomic reports investigating the mechanism of lateral epicondylitis (tennis elbow), we performed cadaveric and clinical studies to investigate the involvement of neurovascular bundles passing through the common extensor origin. We dissected and observed under a light microscope tissue samples of neurovascular bundles passing through the common extensor tendon from 40 upper left and right limbs from cadavers. Tissue samples were prepared by hematoxylin & eosin and Weil's myelin staining. We also investigated the records of 20 patients who had been treated for lateral epicondylitis between 1991 and 2004. From cadavers, we found 60 bundles in the common extensor tendon, each 0.5 to 1.0 mm in diameter, with more bundles in the right than left limbs. Twenty-four of these bundles passed over the vertex of the lateral epicondyle of the humerus, and most of the bundles contained only one artery each. The bundles mostly originated from the radial recurrent artery, passing through the aponeurosis of the extensor corpi radialis brevis, but in some cases originated from the radial collateral artery, passing through the aponeurosis of the triceps brachii muscle. The bundles had a membranous covering when passing through the aponeurosis and produced a hiatus. Histological analysis of resected common extensor tendon tissue, 1 cm in diameter, of patients showed hyaline degeneration and fibrosis formation infiltration. Neurovascular bundles passed through the common extensor tendon in nine cases; six cases showed pulsing bleeding. After a mean follow-up of two years (6–48 months), 16 cases showed excellent results, two showed good results and two showed reliefs. Lateral epicondylitis could be caused by damage to neurovascular bundles when they pass through the common extensor origin; one cause of pain is the neurovascular bundle being compressed when passing through the common extensor tendon, secondary to the pathologic degeneration of the origin of the common extensor tendon.

Introduction: Cricket is a popular, well known and most played common sports in Bangladesh which is dynamic, complex, and vulnerable to injuries. Objective: To find out the common sports injuries among the professional cricket playing students of Bangladesh Krira Shikkha Protisthan (BKSP). Methodology: This was a cross-sectional study with 70 students from the cricket section of BKSP. Data has been collected with a semi-structured survey questionnaire from January to June 2019. Result: The results showed most of the participants are in their second decade of life and the highest percentage of participants age was 20 (27.1%), similarly height (cm) mean and standard deviation (167.43±5.157) and found the highest percentage of participant’s height 27 cm (38.5%). The weights of the respondents were 65.514 ± 7.539 kg and BMI of the respondent were 23.311 ± 2.048. Major playing site 82.9% (n=58) were batsman, 60% (n=42) were bowlers and 18.6% (n=13) were in wicketkeeper. The study found 55.7% (n=39) of the respondents had upper limb injury, 22.9% (n=16) had rotator cuff injuries, 10% (n=7) had tennis elbow, 10% (7) had acute soft tissue injuries, 10% (7) had an ankle sprain and 21.4% (15) had cuff muscle pull. Conclusion: The study found upper limb injuries are most common than lower limb injuries for the cricket trainees in Bangladesh. Moreover, the shoulder is one of the most vulnerable sites of injuries.
