Closed traumatic disruptions of biceps brachii muscle belly are rarely seen. In this paper, we report two rare cases of biceps brachii muscle belly rupture sustained while water-skiing or wakeboarding and discuss the mechanism of injury, management and outcomes after a literature review. A review of published articles revealed only three previously reported cases of water skiing related biceps muscle rupture. It is important to be vigilant of these injuries, given that early recognition and operative intervention with or without direct muscle repair may optimise outcomes.

Introduction: Biceps brachii is one of the functionally important muscles of front of the arm. As the name indicates biceps brachii is having two heads of origin and it inserts on the posterior surface of radial tuberosity. Variations may be present in the form of additional heads of origin or they may be present at its insertion. These variations may affect action of muscle and may cause compression of nearby neurovascular structures. Aim: To determine the variation in anatomy of biceps brachii with respect to its origin, insertion and its nerve supply. Materials and Methods: The present osteological study was conducted on 32 arms of embalmed cadavers (including both right and left) of Department of Anatomy, SRMS IMS, Bareilly, Uttar Pradesh, India from 2015-2018 period. The dissection of arm was done according to standard guidelines and biceps brachii muscle was cleaned. The origin, insertion and nerve supply of biceps brachii muscle was observed and noted for any variation. Results: In the present study an additional head of origin of biceps on right and left side of two cadavers were found. In present study inferomedial origin of biceps brachii was found. The present study also showed the presence of musculotendinous slip at its insertion. This slip was going towards the muscle belly of pronator teres. Conclusion: There are numerous variations seen in biceps brachii which can put a surgeon in dilemma and it may result in iatrogenic injuries. Hence, it is important to have a knowledge about its variations so that such injuries can be prevented.

Introduction Biceps brachii muscle belongs to the flexor group of muscles in arm. As Biceps brachii is double headed muscle. It is one of the known variable muscles of human body in terms of number and morphology. Material and Method During routine human cadaveric dissection for the purpose of teaching medical undergraduates in our department. The upper limb of embalmed adult male cadaver was dissected as per the standard method to note the origin, insertion, and nerve supply of biceps brachii. Results The three headed biceps brachii was found unilaterally on right side in adult male cadaver. The long and short head had normal origin, but third head originated from humerus below insertion of coracobrachialis and inserted with main muscle belly and innervated by musculocutaneus nerve. Conclusion Variant biceps brachii may confuse a surgeon who performs procedures on the arm and may lead to iatrogenic injuries. The surgeons and traumatologists have to keep such muscular variations in mind. So the knowledge of existence of its variation is important for anaesthetists and surgeons.

Aim. To determine the effects of vibration therapy devices exposure with a constant and aperiodic frequency of vibrations on the tissue of the biceps muscle of the shoulder. Material and methods. The study was conducted on 10 volunteers aged 24-35 years. the program Adobe Audition CC 2020, the device for vibration therapy with a constant vibration frequency “Charm 1-t”, the device for vibration therapy with an aperiodic vibration frequency “Individual massager with a pseudo-boiling layer” (MI EPS), the robotic biomechanical diagnostic and training complex with biological feedback CON-TREX were used. The measurement of the maximum strength of the biceps brachii muscle was carried out once to detect sensitivity to vibration, and then during 7 days for the dynamics of power characteristics. The maximum force was measured before exposure to vibrotherapy devices and immediately after exposure using the isokinetic classical mode of operation of the diagnostic system. Results. In a single measurement of biceps strength on one shoulder in a group of women, the average increase in muscle strength after using the Charm 1-T device was 0.8 N (2.3%), after using MI EPS – 1.9 N (6.4%). In the group of men, the average increase in muscle strength after using the device “Charm 1-T” was 1.9 N (3.2%), after using “MI EPS” – 4.6 N (7.2%). At the seven-day follow-up, the average increase in strength in the group of women on the right hand after using the Charm 1-T device was 21.8% (5.6 N), on the left hand after using MI EPS, the increase was 23.2% (6.1 N). In the group of men, the average increase in strength on the right hand after using “Charm 1-T” was 53% (30.7 N), on the left hand after using “MI EPS” – 15.5% (11.5 N). Conclusion. All participants in the study groups were determined to be sensitive to both types of vibration exposure. The study participants demonstrated an increase in strength indicators when testing the biceps muscle of the shoulder, and there was also an improvement in the tolerability of the procedure itself.

Stimulation Of

Many wearable interfaces have been proposed to present force to the upper limb and elbow joint. One way to achieve a compact wearable haptic interface is to use electrical stimulation, and we have suggested that transcutaneous electrical stimulation above the wrist tendon can produce force a sensation in the direction of the muscle stretching; however, it has not been investigated in detail whether the force sensation presented by the electrical stimulation of the tendon occurs in the upper limb joints. In this study, to investigate whether the force sensation is generated when applying electrical stimulation of the skin at the tendon or at the muscle belly of the biceps brachii muscle, we quantitatively evaluated the direction and amount of the force sensation under the aforementioned conditions. The results showed that the electrical stimulation of the tendon produced significant force sensation in the direction of elbow extension. On the other hand, in some participants, the electrical stimulation of the muscle belly worked as a supporting force, resulting in the sensation of weakened force perception. In general, we concluded that the sensation produced by muscle stimulation was different from that produced by stimulation of the tendon.

A general analysis of the behaviour of “Cebus” shows that when this primate moves position to feed or perform another activity, it presents different ways of locomotion. This information shows that the brachial biceps muscle of this animal is frequently used in their locomotion activities, but it should also be remembered that this muscle is also used for other development activities like hiding, searching for objects, searching out in the woods, and digging in the soil. Considering the above, it was decided to research the histoenzimologic characteristics of the brachial biceps muscle to observe whether it is better adpted to postural or phasic function. To that end, samples were taken from the superficial and deep regions, the inserts proximal (medial and lateral) and distal brachial biceps six capuchin monkeys male and adult, which were subjected to the reactions of m-ATPase, NADH-Tr. Based on the results of these reactions fibres were classified as in Fast Twitch Glycolitic (FG), Fast Twitch Oxidative Glycolitic (FOG) and Slow Twitc (SO). In general, the results, considering the muscle as a whole, show a trend of frequency FOG> FG> SO. The data on the frequency were studied on three superficial regions FOG=FG>SO; the deep regions of the inserts proximal FOG=FG=SO and inserting the distal FOG>FG=SO. In conclusion, the biceps brachii of the capuchin monkey is well adapted for both postural and phasic activities.

Estimation of the extrafiber fluid volume in the biceps brachii muscle of the mouse was attempted by pressing the fibers into a thin layer. This caused the fluid from the spaces between the fibers to be displaced to the periphery of the fiber mass. As the thickness of the layer was known, the volume of the extrafiber fluid and the fibers was determined from their areas. The technique consisted of gently pressing the muscle between two glass plates. The thickness of the layer was controlled by plastic film spacers placed between the plates. The optimum thickness for mature mouse biceps muscle was found to be 125 μ. Measurements were carried out on muscles of different sizes, and it was found that the proportion of extrafiber fluid did not change very markedly during postembryonic growth. Investigations were also undertaken to ascertain the effects of starvation and deprivation of water. Starvation was found to increase the percentage of intrafiber water. Deprivation of water was found to result in a considerable decrease in the extrafiber fluid volume but to cause no dehydration of the fibers themselves.
