The case study looked at a 21 year old female netball player who suffered a grade II hamstring strain to the Biceps femoris muscle. The subject was sprinting and they quickly changed direction to intercept the ball. On landing the subject experienced a sharp pain at the back of the thigh and where taken to the hospital. After physical examinations at the University Hospitals Coventry and Warwickshire the doctor and physiotherapist diagnosed the injury as a grade II Biceps femoris strain (Appendix 1). The patient went through rehabilitation and was able to return to play after 7 weeks.
Background
The hamstring muscle group consists of three long muscles: Biceps femoris, semitendinosus and semimembranosus, which are located at the posterior compartment of the thigh (figure 1). The muscles (except the short head biceps femoris) cross both the hip and the knee joint (Bryan et al. 2010. The hamstring muscle extends the hip joint, flexes the knee joint and also rotates both joints (Drake et al 2005). Figure 1: Image illustrating the muscles of the Posterior compartment of the thigh (Drake et al. 2005)
The subject experienced a partial tear to the biceps femoris (figure 2) which is located on the lateral side of the posterior compartment of the thigh (Agur and Dalley 2005). It comprises of the long head, which originates from the ischial tuberosity and the short head originates from the linea aspera on the shaft of the femur. The short head and the long head join distally to
In order to test the passive sufficiency of a bi-articular structure, such as a muscle, both joints which that structure crosses must first be identified. Additionally, the movements of those two joints which will constrain that structure must be identified. Next, one joint must be selected, and placed into the position that may constrain the structure. At the same time, the other joint must be placed in the position which will NOT put further strain on that structure. The selected joint must then be measured for its range of motion. Next, the same must be done with the selected joint, but in contrast, the other joint must be placed in the position which WILL further constrain the bi-articular structure. Once that has been done, the selected joint’s range of motion must be measured once more.
Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone, but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions, like the genioglossus muscle, for example, originates at the chin (geneion) and inserts in the tongue (glossus). Some muscles are named for the arrangement of the fascicle groups. For example the rectus abdominus is the straight muscle that is in the adbominus.
As explained by Opar (3) the hamstring consists of three muscles, biceps femoris (BF), semitendinosus (ST) semimembranosus (SM), this composes a muscle group crossing the hip and knee joint that acts synergistically in extending the hip and flexing the knee.
Identify the major surface muscles located in the body. Where are the orgins and insertions of these muscles? List the intended actions as well as an exercise or movement for each. A minimum of fifteen muscles is required.
3) What are side affects to having a hamstring strain? Would you be able to return to a sport exactly the same after it is healed?
A pulled hamstring are injuries to three groups of muscles in the back of the thigh. The muscle is not very widely used when a person is standing or walking.
These muscles begin at the ischial tuberosity, which is at the bottom of the pelvis. The muscles meet at the knee joint and end at the lower leg, where they are joined together through connective tissue that attach the tendons to the bones like double-sided tape. The hamstring muscle groups work to help extend the leg back and provide motion at the knee. Due to the crossing
The anatomy is a major contributor to any injury. The three hamstrings are the semimembranosus, semitendinosus, and the biceps femoris. The hamstrings are responsible for flexing the knee and extending the hip
The knee joint is formed by the articulation of the distal end of the femur and the proximal end of the tibia. The fibula is only involved to the extent that it serves as an attachment site for connective tissue. In this paper, the anatomy of the joint will be discussed.
A Distal Biceps Rupture occurs when the tendon attaching the biceps muscle to the elbow is torn from the bone. The Distal Biceps Rupture is attached to a small bump on the radius bone of the forearm. This small bony bump is called the radial tuberosity. The radius is the smaller of the two bones between the elbow and the wrist that make up the forearm. The radius goes from the outside edge of the elbow to the thumb side of the wrist.
During the operation, the patient was put under general anaesthesia and positioned laterally (George et al., 2008). For a lesion in the proximal region of the right femur, the patient initially lying supine was turned to the left lateral position, so that the right lateral side of the patient faced up; this position allowed for a greater view of the lesion area during surgery (Chen et al., 2013). The patient was draped while exposing the intended surgical region between the pelvis and the proximal upper leg (George et al., 2008). The epidermis, dermis, and subcutaneous layers in the region of the lesion were cut away, exposing the deeper tissue layers (Chen et al., 2013). Incisions continued through the deep fascia, exposing the gluteus medius, gluteus minimus, and vastus lateralis muscles (Chen et al., 2013). The right gluteus medius and minimus, lateral abductor muscles of the right thigh, and the right vastus lateralis muscle were cut away while their insertions remained intact (Chen et al., 2013). The surgeon made a lateral incision from a region inferior to the right anterior superior iliac spine toward the right gluteus medius muscle, until the greater trochanter was exposed (Chen et al., 2013). It should be noted that there are vascular structures present within the vicinity of the lesion, such as the medial and lateral femoral circumflexes; great care was taken to avoid such structures to minimize blood loss (Drake et al.,
The anterior aspect of the thigh is dominated by the _____, a large muscle with four heads
The vastus lateralis muscle forms part of the quadriceps muscle group of the upper leg and can be found on the anteriolateral aspect of the thigh. This muscle is more commonly used as the site for IM injections as it is generally thick and well formed in individuals of all ages and is not located close to any major arteries or nerves. It is also readily accessed. The middle third of the muscle is used to define the injection site. This third can be determined by visually dividing the length of the muscle that originates on the greater trochanter of the femur and inserts on the upper border of the patella and tibial tuberosity through the patella ligament into thirds. Palpation of the muscle is required to determine if sufficient body and mass is present to undertake the procedure.
There are four different Hamstring muscles that run along the back of your thigh. These four muscles are called: semimembranosus and semitendinosus (medially) and biceps femoris – short and long heads (laterally). Hamstrings strains can occur for multiple reasons.
The gluteal region is an anatomical area located posteriorly to the pelvic girdle, at the proximal end of the femur. The muscles in this region move the lower limb at the hip joint. The gluteal muscle is composed of three muscles that make up the buttocks: Gluteus Maximus, Gluteus Medius, and Gluteus Minimus. They are supplied by the gluteal nerves and vessels, which reach them through the greater sciatic foramen. The gluteus maximus is the largest of the gluteal muscles and one of the strongest muscles in the human body. The gluteus medius is the second largest gluteal muscle and gluteus minimus is the smallest.
