View Full Profile. Anterior rotation of the innominate bone: Ipsilateral or contralateral cause? In much that is published, the anterior rotation of the innominate bone is viewed as caused by the quadriceps, sartorius, etc. Try this: For every anterior rotation of the innominate bone try a lateral distorition of these muscles on the ipsilateral side. In the vast majority of cases, the quads and sartorius move laterally with little problem and no pain.

Further, treating these muscles does not resolve the anterior rotation of the innominate bone. In the majority of cases, the contralateral anterior rotation of the innominate bone corrects to some extent and may in fact "overcorrect".

Re: Anterior rotation of the innominate bone: Ipsilateral or contralateral cause? Neuromuscular, Do you mean anterior tilt of the pelvis with anterior rotation of the innominate?

And what do you mean by lateral distortion? Dear Iliostolos: Thank you for your reply. What I am asking others to consider is that the contralateral adductor longus exerts a pull on the pubis ramus which in turn causes a opposing action by the psoas on the ipsilateral side as the innominate bone which has the PSIS superior to the ASIS.

If you wish to call this tilt, do so. What I am stating this that the innominate bone has rotated. There is so much difference in what people call the movements that the most important thing is to remember that the contralateral adductor longus is causing the PSIS superior to the ASIS on the innominate bone and not the quads or the sartorius. Is this what you find?Standard anatomical terms of location are used to unambiguously describe the anatomy of animalsincluding humans.

The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position.

ipsilateral rotation

This position provides a definition of what is at the front "anterior"behind "posterior" and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebratessome terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle "proximal" or further from the middle "distal".

International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatomy, for example, Terminologia Anatomica for humans, and Nomina Anatomica Veterinaria for animals. These allow parties that use anatomical terms, such as anatomistsveterinariansand medical doctors to have a standard set of terms to communicate clearly the position of a structure. Standard anatomical and zoological terms of location have been developed, usually based on Latin and Greek words, to enable all biological and medical scientists, veterinariansdoctors and anatomists to precisely delineate and communicate information about animal bodies and their organs, even though the meaning of some of the terms often is context-sensitive.

For humans, one type of vertebrate, and other animals that stand on two feet bipedsterms that are used are different from those that stand on four quadrupeds. Unique terms are used to describe animals without a backbone invertebratesbecause of their wide variety of shapes and symmetry.

Because animals can change orientation with respect to their environment, and because appendages like limbs and tentacles can change position with respect to the main body, terms to describe position need to refer to an animal when it is in its standard anatomical position. This helps avoid confusion in terminology when referring to the same organism in different postures. Many anatomical terms can be combined, either to indicate a position in two axes simultaneously or to indicate the direction of a movement relative to the body.

For example, "anterolateral" indicates a position that is both anterior and lateral to the body axis such as the bulk of the pectoralis major muscle. In radiologyan X-ray image may be said to be "anteroposterior", indicating that the beam of X-rays passes from their source to patient's anterior body wall through the body to exit through posterior body wall.

Anatomical terms describe structures with relation to four main anatomical planes : [2]. The axes of the body are lines drawn about which an organism is roughly symmetrical. An organism that is symmetrical on both sides has three main axes that intersect at right angles.

Anatomical axes in a human, similar for other orthograde bipedal vertebrates. Spheroid or near-spheroid organs such as testes may be measured by "long" and "short" axis. Other terms are used as suffixesadded to the end of words:. Superior from Latin super 'above' describes what is above something [21] and inferior from Latin inferus 'below' describes what is below it. As a second example, in humans, the neck is superior to the chest but inferior to the head. Anterior from Latin ante 'before' describes what is in front, [23] and posterior from Latin post 'after' describes what is to the back of something.

These terms describe how close something is to the midline, or the medial plane. Medial from Latin medius 'middle' describes structures close to the midline, [2] or closer to the midline than another structure.

For example, in a human, the arms are lateral to the torso. The genitals are medial to the legs. The terms "left" and "right" are sometimes used, or their Latin alternatives Latin : dexterlit. However, as left and right sides are mirror imagesusing these words is somewhat confusing, as structures are duplicated on both sides.

For example, it is very confusing to say the dorsal fin of a dolphin is "right of" the left pectoral finbut is "left of" the right eyebut much easier and clearer to say "the dorsal fin is medial to the pectoral fins". Varus from Latin 'knock-kneed' and valgus from Latin 'bow-legged' are terms used to describe a state in which a part further away is abnormally placed towards varus or away from valgus the midline.

The terms proximal from Latin proximus 'nearest' and distal from Latin distare 'to stand away from' are used to describe parts of a feature that are close to or distant from the main mass of the body, respectively. Although the direction indicated by "proximal" and "distal" is always respectively towards or away from the point of attachment, a given structure can be either proximal or distal in relation to another point of reference.Metrics details.

Combined ipsilateral femoral neck and shaft fractures are an uncommon type of fractures. A number of different implant options are available for the management of this injury. Two-device procedures were suggested because of the higher rate of malunion by single-device treatment.

However, surgical treatment using a cephalomedullary nail is still an alternative option that provides better mechanical advantage and minimal invasion. This study details the technique of treating these pattern fractures with proximal femoral nail anti-rotation II PFNA-II to achieve an acceptable reduction in both fracture sites.

Under the special technique by using the PFNA II, all ten cases achieved optimal reduction and alignment of both fracture sites in intra-operative fluoroscopy. There was no intra-operative complication noted. After 6 months of follow-up, radiography revealed proper alignment and well union of the fractures.

Fixation of ipsilateral femoral neck and shaft fractures with a single construct provides advantages of good biomechanical function, minimal invasion, reduced blood loss, and less operation time when comparing to two-device fixation.

Thus, if acceptable reduction could be achieved, fixation by one PFNA II was a good alternative choice for this injury pattern. In the past research, most surgeons have recommended fixation with two separate prostheses because the use of a single cephalomedullary device often results in higher rates of complication and malunion.

Ipsilateral versus Contralateral: What Arm & Leg Combination To Use

In spite of the lower rate of malreduction in two-device constructs, a non-traumatic fracture in the gapped area between two implant constructs in a patient with healed ipsilateral intertrochanteric and shaft fractures has been observed [ 34 ].

Comparing to two-device techniques, fixation of both fractures with a single construct with either reconstructive or cephalomedullary nails provides advantages such as minimal invasion, reduced blood loss, and less operation time. In addition, there will be no gapped region and no concerned stress riser in a single nailing construct.

Proximal femoral nail antirotation PFNA was designed initially for the fixation of peritrochanteric fractures while the second-generation nail was introduced specifically to accommodate the femoral size and geometry of Asians. Femoral neck fractures might be one of contraindication of this construct. However, difficulties in obtaining rotational alignment of nail and reduction of a neck fracture, especially, when the femoral neck injury is displaced were reported [ 789 ].

When using antegrade cephalomedullary nails to treat femoral neck and shaft fractures, the floating trochanteric fragment Fig. Some reports have suggested substantial internal rotation of this floating fragment may be helpful during nailing and placement of cephalomedullary head screw [ 8 ]. In ipsilateral femoral neck and shaft fractures, femur bone can be divided into three parts: femoral head fragment, floating trochanteric fragment, and distal femur fragment.

This study investigates the case series clinically and radiographically and presents the techniques treating ipsilateral femoral neck and shaft fractures with PFNA-II to improve optimal reduction in both fracture sites. This is a retrospective case series in a single referral hospital. In this study, we reviewed the cases of the ipsilateral femoral neck and shaft fractures over a period of 2 years August to August using a single implant of cephalomedullary nail fixation. The patients who underwent two-implant fixation or a single-implant fixation other than cephalomedullary nail fixation were excluded.

We also excluded one of the patients in whom the proximal femoral fractures were initially missed and revised with a cephalomedullary fixation. For each patient, the basic demographic characteristics were collected. Besides, radiographic findings for both fracture sites were also recorded. The PFNA-II is an intramedullary device designed for fixation of proximal femoral fractures involving trochanteric regions.

Its anti-rotated helical blade can compact cancellous bone and thus increase stability against rotation and varus collapse [ 10 ].

With different nail lengths, it could be used to allow the stabilization of shaft fracture at any level. The procedure is performed under a patient in supine on a fracture table as a regular closed nailing procedure.

Traction force for the affected limb can be controlled by the distal support of boot on the foot. Abduct the unaffected leg as far as possible to allow free fluoroscopic examination. Minimal invasion is one of the main aims in closed nailing. However, mini-open approach to the shaft fracture to achieve better anatomic reduction by facilitating guide wire passage or to rotate nail in an optimal position can be considered if necessary. After a proper pre-operative position and reduction under fracture table, the entry point is determined on the tip of the greater trochanter and the guide wire is inserted through the shaft fracture site and deep into distal metaphyseal level.

After inserting the guide wire in a suitable depth, medullary canal is prepared by reamed to a diameter 0. While the PFNA-II nail is inserted into the medullary canal and adequate depth of the nail is reached, the optimal blade anteversion can be adjusted by the rotation of the targeting guide in the mediolateral view. In conventional techniques of treating a pertrochanteric fracture, the targeting guide was usually externally rotated to obtain adequate anteversion of blade position.The abdominal internal oblique musclealso internal oblique muscle or interior obliqueis an abdominal muscle in the abdominal wall that lies below the external oblique muscle and just above the transverse abdominal muscle.

The muscle fibers run from these points superiomedially up and towards midline to the muscle's insertions on the inferior borders of the 10th through 12th ribs and the linea alba. In males, the cremaster muscle is also attached to the internal oblique. The internal oblique is supplied by the lower intercostal nerves, as well as the iliohypogastric nerve and the ilioinguinal nerve.

The internal oblique performs two major functions. Firstly as an accessory muscle of respirationit acts as an antagonist opponent to the diaphragmhelping to reduce the volume of the chest cavity during exhalation. When the diaphragm contracts, it pulls the lower wall of the chest cavity down, increasing the volume of the lungs which then fill with air.

Conversely, when the internal obliques contract they compress the organs of the abdomen, pushing them up into the diaphragm which intrudes back into the chest cavity reducing the volume of the air-filled lungs, producing an exhalation. Secondly, its contraction causes ipsilateral rotation and side-bending. It acts with the external oblique muscle of the opposite side to achieve this torsional movement of the trunk. For example, the right internal oblique and the left external oblique contract as the torso flexes and rotates to bring the left shoulder towards the right hip.

For this reason, the internal obliques are referred to as "same-side rotators.

The effect of phencyclidine PCP on rotational behavior in rats with unilateral 6-hydroxydopamine 6-OHDA -induced lesions of the substantia nigra was examined and compared to the effects of d-amphetamine and apomorphine.

PCP, like d-amphetamine, induced ipsilateral rotation indicating a presynaptic effect on dopamine DA neurons whereas apomorphine, a direct acting agonist, caused contralateral rotation. Pretreatment with alpha-methyparatyrosine inhibited PCP-induced rotation approximately to the same extent as it inhibited d-amphetamine-induced rotation, but did not significantly reduce apomorphine-induced contralateral turning, further indicating that PCP has a presynaptic effect on DA neurons.

Anti-cholinergic effects on PCP may also contribute to the ipsilateral rotation noted.

For nearly 20 years there has been a surge in research that has led us to understand more about the role of muscle retraining in rehabilitation of neck pain.

As this research mounts we begin to understand more and more about the association between neck pain and motor control dysfunction. Initially, around the early s, there was a lot of research orientated towards identifying and quantifying deficits in the deep cervical neck flexor muscles - longus colli and longus capitus.

Since that time, further research has investigated the presence of motor control dysfunction across a range of cervical spine disorders and aimed to determine the best treatment approaches for such deficits. Despite the fact that many papers address cervical spine flexor and extensor groups equally, I certainly feel there has been a biased approach clinically and educationally towards retraining of the deep neck flexor muscles.

The purpose of this blog therefore, and the next 3, is to review the clinical anatomy of the cervical spine, the assessment of both deep cervical flexors and extensors, discuss the role of sitting posture in neck pain and to present the phases of motor control rehabilitation. Join me on this journey to learn more about how to make the most impact with your motor control rehabilitation for patients with neck pain. To begin at the beginning - it is important to clearly understand what muscles are being referred to under the topic of cervical spine motor control.

When classifying muscles, it can be useful to think of them conceptually as global movers and local stabilisers. Global movers are involved in the generation of torque and produce range of movement. They function in a phasic manner i. When dysfunctional there is spasm, pain and restricted range of movement. Local stabilisers are the deeper muscles that control segmental control and neutral positioning of a joint.

Their activity is tonic rather than phasic and they operate at much lower levels of contraction for long periods of time. Dysfunction in the local muscles results in inhibition of function, delayed timing or recruitment deficiencies and loss of segmental control and neutral joint positioning. There are three main groups of cervical muscles that form a sleeve around the vertebral column and enable control of posture and segmental movements:.

When it comes to talking about cervical motor control I am confident that we are all familiar with deep neck flexors DNF. The literature often refers to the superficial muscles which become overactive in the presence of neck pain and the deep neck flexors which become dysfunction. It can be easy to continue referring to them as 'superficial' and 'deep' but to make a bigger impact we need to know exactly which muscles are being referred to.

The more superficial flexor muscles of the cervical spine include sternocleidomastoid SCM and anterior scalenes AS :.These are common things I hear all the time in my training sessions, especially with movements that require split stance or single leg stance and holding a weight with on arm. It can seem confusing to put it all together, especially with novel movements where the exact goal may not seem apparent, and where the positioning can take advantage of fascial sling systems and neural drive not readily visible in most anatomy charts.

Ipsilateral means using the same side arm and leg. For instance, this would me like a boxer throwing a punch with their right hand and driving off their right foot. The benefit to a movement like this is the generation of joint compressive tension throughout the entire system where the impulse from the foot travels fairly efficiently through the entire body and extends through a solid lever system.

The development of power along this line typically hinges on the ability of the glutes to pull the hip into extension and external rotation. This external rotation of the hip, when the foot is planted, causes the upper body to rotate through and generate some snap. Watch how Mike Tyson, one of the most feared hitters of all time generates stupid amounts of hip extension and rotation with his body uppercut combo:.

The lateral fascial line, shown by Thomas Myers in Anatomy Trainsencapsulates a lot of the anatomical linkages between the driving foot and the arm throwing the blows. When under contraction, the system can produce a great level of rigidity through the entire line, which can make it sort of like a wound up spring.

This elasticity and rigidity is not only used to produce power up through the hands, but produce power down through the foot, like in walking or running. The drive back and down from the leg is met with a drive up and forward from the same side arm. The extension and external rotation of the hip is met with an antagonistic movement from the opposing core, involving flexion, rotation and lateral flexion, which produces the upper-lower rotation seen in locomotion.

This is a common issue in runners who get a lot of lateral hip pain, IT band issues, medial knee pain and shin splits, which is pretty much any runner who prides volume over technique.

You could also see a coxalgic gait, where the person is leaning hard over the hip to try to reduce the stability requirement of the contralateral stabilizing system. The 22 mile mark posture of Every. The continuity seems to break down somewhat when it goes from horizontal force production to vertical force production. This case seems to favour contralateral linkage, as seen in a typical lay up in basketball where the shooting arm extends off the contralateral leg.

So what does this mean when it comes to training? Essentially, any movement that involves pressing or some level of drive comes into ipsilateral continuation. A powerful force in this movement is the extension and rotation of the right hip, as mentioned above.

Can you stretch the line? Sure, and one of my favorite ways of doing this is to use a lunge with a back rotation of the upper body. At a more neurodevelopmental level, rolling patterns take an ipsilateral pattern in a new direction.

A lot of people with spinal issues tend to really struggle with rolling, specifically as it relates to the duality of stability and mobility through the system. Where ipsilateral work could be considered the driving movement, contralateral work could be considered pull or reach dominant movements.

Much of the contralateral work relies on using an interconnected line of tissue known as the posterior functional line. This line connects the gluteus maximus of one hip to the opposite side latissimus dorsi muscle, which essentially crosses the low back in an X-shape, and provides a level of stabilization and also acceleration.

The main role of this system is to produce force to pull towards the body, such as in a single leg deadlift. The glute and lat stretch simultaneously, which happens to get the low back stabilized through the thoracolumbar fascia. These are all fancy words, but they essentially mean this is easier to do with less to no pain compared to a bilateral deadlift or hip hinge movement, and is a cornerstone movement I use with a lot of low back pain clients due to the movement from the hip and pull through this chain.

A secondary use of this line is as an antagonist for the drive from the ipsilateral line. When runningthe one foot drives into the ground while the other knee drives up and forward. This forward knee drive stretches and tenses the functional line, especially when coupled with the arm reach. This stretch provides a brake for the drive side, and allows for an elastic recoil effect to bring the next leg into position to drive into the ground for continued acceleration.

Combining the ipsilateral drive with the contralateral pull is one of the basic tennets of locomotion, much like a crawling pattern. Contralateral work provides the greatest reach potential for pulling, which means the right hand has the left leg forward or standing on. Funny enough, they both wind up being kind of the same position, which makes it that much easier.
