Investing abdominal fascial planes
For spine surgeons, when mobilizing the abdominal, anterior pararenal, and perirenal cavities to exposure the PPS, it is significant that the psoas fascia and the anterior layer of the TF fuses with the posterior RF. Go to: Safe and reliable exposure to retroperitoneal space for lateral surgery In contrast to the descriptions of the RF published by Gerota and Zuckerkandl over years ago and that of the LCF published in s, some of the surgical anatomy around the retroperitoneum remains controversial.
The surgical interpretation of the retroperitoneum including the RF and LCF has changed over the years. Some of these changes can be observed in textbooks and manuscripts. This suggests that difficulty in discrimination result in misinterpretation of the laminar configurations during surgery. Laparoscopic urologic surgeons have emphasized a correct understanding of the LCF in the lateral aspect of the kidney , However, the LCF remains unknown to many surgeons, especially spine surgeons, unfamiliar with older orthopedic or spinal surgery textbooks.
As a result, most spine surgeons have a misunderstanding that the retroperitoneum is the compartmentalized space bounded anteriorly by only one membrane namely the peritoneum in any anterior aspect. Knowledge of the complex anatomy of the entities lying between the posterior abdominal wall and peritoneum, and recognition of common variations and their potential implications are crucial for successful surgery using a retroperitoneal approach.
However, there is a substantial difference between the two techniques regarding the first process of exposing the retroperitoneal space. The original OLIF technique use an antero-lateral approach similar to the conventional open anterior approach, in which the first process in exposing the retroperitoneal space to the preperitoneal space is confined between the parietal peritoneum of the anterior abdominal wall and the TF, including preperitoneal fat.
Conversely, XLIF technique is true lateral or postero-lateral approach, in which the first process of exposing the retroperitoneal space to the PPS is confined between the posterior RF anteriorly and the TF posteriorly Fig. Furthermore, it is clinically significant for spine surgeons that the FF fuse the ascending or descending colon to the lateral or posterior aspect of the abdominal cavity, which lies closely anterior to the anterior RF or the LCF. This suggests that injury of the peritoneum or the fasciae in the first process of the exposure to the retroperitoneal space has a higher possibility of being injury to the ascending or descending colon in a true lateral approach than in an anterolateral or conventional open anterior approach.
Figure 8. Lateral lumbar interbody fusion approaches. In the second LLIF process, mobilization of the peritoneum and its content or retroperitoneal content anteriorly is required to expose the PPS and allow subsequent lateral access. To provide this mobilization, the posterior RF and the LCF or the peritoneum should be detached from the TF and the psoas fascia, and extended into the immediate anterior side of the psoas.
Understanding of the anatomical structures in the retroperitoneum, especially retroperitoneal fasciae, has recently advanced with the development of image diagnosis and innovative surgical techniques. However, such a clear view and identification of the membrane and fasciae cannot be observed in the PPS during actual surgery Fig.
This suggests that correct anatomical recognition of the posterior RF and the LCF during operation is sometimes difficult. In addition, the pararenal space contains connective tissue fibers similar to the perirenal space Therefore, clear anatomic assessment and identification of the pathway for exposure to the PPS in preoperative images is beneficial, and gentle and meticulous surgical detachment of the posterior RF, LCF, or the peritoneum from the TF and the psoas fascia is essential for safe and reliable lateral approach surgery.
An alternative technique when there is no clear identification of the peritoneum and fasciae during surgery is the detachment of the psoas fascia and the fascia of the quadratus lumborum muscle from its own myotome, and mobilization of the peritoneum, the posterior RF, LCF, the psoas and quadratus lumborum fascia as one membrane. Figure 9. An anatomic cross-section below midlevel of the left kidney.
The anatomic cross-section shows the termination of the posterior renal fascia in relationship to the fascia of the quadratus lumborum muscle arrow. A clear view and identification of these fasciae could not be observed at the posterior pararenal space because this relationship is variable and the medial extent of the posterior pararenal space varies from patient to patient. The FF, resulting from adherence of the peritoneum of the colonic mesentery with the primary posterior peritoneum, consists of thin 0.
The normal thickness of these fascial planes is mm This means the distance between the posterior or lateral aspect of the ascending or descending colon and the anterior wall of the PPS including the peritoneum, posterior RF and LCF is less than 2 mm. Although the thickness of this fascia plane varies because of containing connective tissue fibers and fat tissue, this fascia plane is less thin than commonly identified by many spinal surgeons during surgery.
These patients have a high possibility of colonic perforation during exposure to the PPS and the entire LLIF procedure after the setting of the retractor. To avoid colonic perforation during LLIF, anatomic assessment of the descending and ascending colon using preoperative abdominal computed tomography scans e. Although special instruments and light equipment used in recent novel LLIF surgery are used for minimal-incision surgery as a less invasive alternative to conventional open ALIF, the most important factor is the safe and reliable creation of a spacious cavity in the retroperitoneum by entry along the correct planes.
Figure Go to: In conclusion Lateral approach spine surgery can provide effective interbody stabilization and correction, and indirect neural decompression with minimal-incision and less invasive surgery compared with conventional open ALIF. However, because lateral approach surgery is fundamentally retroperitoneal approach surgery, there is potential risk to intra- and retroperitoneal structures including viscera and vessels as seen with a conventional open anterior approach.
Minimal-incision and less invasive lateral surgery may be a trade-off with the limited visualization of the retroperitoneal space and minimized working space. An innovative lateral approach technique has demonstrated different anatomical views, but requires reconsideration of the traditional surgical anatomy in more detail than a traditional open anterior approach. Correct anatomical recognition for the retroperitoneum is essential to success in lateral approach surgery.
It must be clear to the spine surgeon that the retroperitoneal membrane and fascia are more multilayered and complex than commonly understood. Therefore, preoperative abdominal images will support more efficient surgical consideration about the retroperitoneal membrane and fascia in lateral approach surgery. Such anatomical knowledge is also useful in a conventional open approach.

The body has been sectioned in the median plane to show the abdominal and pelvic cavities as subdivisions of the continuous abdominopelvic cavity. Nine regions of the abdominal cavity are used to describe the location of abdominal organs, pains, or pathologies Table 2.
The regions are delineated by four planes: two sagittal vertical and two transverse horizontal planes. The two sagittal planes are usually the midclavicular planes that pass from the midpoint of the clavicles approximately 9 cm from the midline to the midinguinal points, midpoints of the lines joining the anterior superior iliac spine ASIS and the pubic tubercles on each side. TABLE 2. Both of these planes have the advantage of intersecting palpable structures. Some clinicians use the transpyloric and interspinous planes to establish the nine regions.
The transpyloric plane, extrapolated midway between the superior borders of the manubrium of the sternum and the pubic symphysis typically the L1 vertebral level , commonly transects the pylorus the distal, more tubular part of the stomach when the patient is recumbent supine or prone Fig.
Because the viscera sag with the pull of gravity, the pylorus usually lies at a lower level when the individual is standing erect. The transpyloric plane is a useful landmark because it also transects many other important structures: the fundus of the gallbladder, neck of the pancreas, origins of the superior mesenteric artery SMA and hepatic portal vein, root of the transverse mesocolon, duodenojejunal junction, and hila of the kidneys.
For more general clinical descriptions, four quadrants of the abdominal cavity right and left upper and lower quadrants are defined by two readily defined planes: 1 the transverse transumbilical plane, passing through the umbilicus and the intervertebral [IV] disc between the L3 and L4 vertebrae , dividing it into upper and lower halves, and 2 the vertical median plane, passing longitudinally through the body, dividing it into right and left halves Table 2.
It is important to know what organs are located in each abdominal region or quadrant so that one knows where to auscultate, percuss, and palpate them Table 2. The wall is musculo-aponeurotic, except for the posterior wall, which includes the lumbar region of the vertebral column. The boundary between the anterior and lateral walls is indefinite, therefore the term anterolateral abdominal wall is often used.
Some structures, such as muscles and cutaneous nerves, are in both the anterior and lateral walls. The anterolateral abdominal wall extends from the thoracic cage to the pelvis. Subdivisions of abdominal wall. A transverse section of the abdomen demonstrates various aspects of the wall and its components. Abdominal contents, undisturbed, and layers of anterolateral abdominal wall.
The anterior abdominal wall and soft tissues of the anterior thoracic wall have been removed. Most of the intestine is covered by the apron-like greater omentum, a peritoneal fold hanging from the stomach. Layers of the anterolateral abdominal wall, including the trilaminar flat muscles, are shown.
The anterolateral abdominal wall consists of skin and subcutaneous tissue superficial fascia composed mainly of fat, muscles and their aponeuroses and deep fascia, extraperitoneal fat, and parietal peritoneum Fig. The skin attaches loosely to the subcutaneous tissue, except at the umbilicus, where it adheres firmly. Most of the anterolateral wall includes three musculotendinous layers; the fiber bundles of each layer run in different directions.
This three-ply structure is similar to that of the intercostal spaces in the thorax. Fascia of the Anterolateral Abdominal Wall The subcutaneous tissue over most of the wall includes a variable amount of fat. It is a major site of fat storage. Males are especially susceptible to subcutaneous accumulation of fat in the lower anterior abdominal wall.
In morbid obesity, the fat is many inches thick, often forming one or more sagging folds L. Superior to the umbilicus, the subcutaneous tissue is consistent with that found in most regions. Inferior to the umbilicus, the deepest part of the subcutaneous tissue is reinforced by many elastic and collagen fibers, so it has two layers: the superficial fatty layer Camper fascia and the deep membranous layer Scarpa fascia of subcutaneous tissue.
The membranous layer continues inferiorly into the perineal region as the superficial perineal fascia Colles fascia , but not into the thighs. Superficial, intermediate, and deep layers of investing fascia cover the external aspects of the three muscle layers of the anterolateral abdominal wall and their aponeuroses flat expanded tendons and cannot be easily separated from them.
The investing fascias here are extremely thin, being represented mostly by the epimysium outer fibrous connective tissue layer surrounding all muscles—see Introduction superficial to or between muscles. The internal aspect of the abdominal wall is lined with membranous and areolar sheets of varying thickness constituting endoabdominal fascia. Although continuous, different parts of this fascia are named according to the muscle or aponeurosis it is lining. The portion lining the deep surface of the transversus abdominis muscle and its aponeurosis is the transversalis fascia.
The glistening lining of the abdominal cavity, the parietal peritoneum, is formed by a single layer of epithelial cells and supporting connective tissue. The parietal peritoneum is internal to the transversalis fascia and is separated from it by a variable amount of extraperitoneal fat. Muscles of Anterolateral Abdominal Wall There are five bilaterally paired muscles in the anterolateral abdominal wall Fig.
Their attachments are demonstrated in Figure 2. Muscles of anterolateral abdominal wall. It extends from the pubic crest of the hip bone to the linea alba. This small muscle draws down on the linea alba. The three flat muscles are the external oblique, internal oblique, and transversus abdominis.
The muscle fibers of these three concentric muscle layers have varying orientations, with the fibers of the outer two layers running diagonally and perpendicular to each other for the main part, and the fibers of the deep layer running transversely. All three flat muscles are continued anteriorly and medially as strong, sheet-like aponeuroses Fig. Between the midclavicular line MCL and the midline, the aponeuroses form the tough, aponeurotic, tendinous rectus sheath enclosing the rectus abdominis muscle Fig.
The aponeuroses then interweave with their fellows of the opposite side, forming a midline raphe G. The decussation and interweaving of the aponeurotic fibers here is not only between right and left sides but also between superficial and intermediate and intermediate and deep layers.
Structure of anterolateral abdominal wall. Intramuscular and intermuscular fiber exchanges within the bilaminar aponeuroses of the external and internal oblique muscles are shown. Transverse sections of the wall superior and inferior to the umbilicus show the makeup of the rectus sheath. The two vertical muscles of the anterolateral abdominal wall, contained within the rectus sheath, are the large rectus abdominis and the small pyramidalis. The attachments of the external oblique are demonstrated in Figure 2.
In contrast to the two deeper layers, the external oblique does not originate posteriorly from the thoracolumbar fascia; its posteriormost fibers the thickest part of the muscle have a free edge where they span between its costal origin and the iliac crest Fig 2. The fleshy part of the muscle contributes primarily to the lateral part of the abdominal wall.
Its aponeurosis contributes to the anterior part of the wall. Anterolateral abdominal wall. In this superficial dissection, the anterior layer of the rectus sheath is reflected on the left side. Observe the anterior cutaneous nerves T7—T12 piercing the rectus abdominis and the anterior layer of the rectus sheath. The three flat abdominal muscles and the formation of the inguinal ligament are demonstrated. The muscle fibers become aponeurotic approximately at the MCL medially and at the spino-umbilical line line running from the umbilicus to the ASIS inferiorly, forming a sheet of tendinous fibers that decussate at the linea alba, most becoming continuous with tendinous fibers of the contralateral internal oblique see Fig.
For example, the right external oblique and left internal oblique work together when flexing and rotating to bring the right shoulder toward the left hip torsional movement of trunk. Inferiorly, the external oblique aponeurosis attaches to the pubic crest medial to the pubic tubercle. The inferior margin of the external oblique aponeurosis is thickened as an undercurving fibrous band with a free posterior edge that spans between the ASIS and the pubic tubercle as the inguinal ligament Poupart ligament Figs.
Inferior abdominal wall and inguinal region of a male. The aponeurosis of the external oblique is partly cut away, and the spermatic cord has been cut and removed from the inguinal canal. Palpate your inguinal ligament by pressing deeply into the center of the crease between the thigh and trunk and moving the fingertips up and down.
Inferiorly the inguinal ligament is continuous with the deep fascia of the thigh. The inguinal ligament is therefore not a freestanding structure, although—as a useful landmark—it is frequently depicted as such. It serves as a retinaculum retaining band for the muscular and neurovascular structures passing deep to it to enter the thigh.
The inferior parts of the two deeper anterolateral abdominal muscles arise in relationship to the lateral portion of the inguinal ligament. The complex modifications and attachments of the inguinal ligament, and of the inferomedial portions of the aponeuroses of the anterolateral abdominal wall muscles, are discussed in detail with the inguinal region later in this chapter.
Except for its lowermost fibers, which arise from the lateral half of inguinal ligament, its fleshy fibers run perpendicular to those of the external oblique, running superomedially like your the fingers when the hand is placed over your chest.
Its fibers also become aponeurotic at the MCL and participate in the formation of the rectus sheath. The attachments of the internal oblique are demonstrated in Figure 2. Formation of rectus sheath and neurovascular structures of anterolateral abdominal wall. In this deep dissection, the fleshy portion of the external oblique is excised on the right side, but its aponeurosis and the anterior wall of the rectus sheath are intact.
The anterior wall of the sheath and the rectus abdominis are removed on the left side so that the posterior wall of the sheath may be seen. Lateral to the left rectus sheath, the fleshy part of the internal oblique has been cut longitudinally; the edges of the cut are retracted to reveal the thoraco-abdominal nerves coursing in the neurovascular plane between the internal oblique and the transversus abdominis.
Sagittal section through the rectus sheath of the anterior abdominal wall. This transverse, circumferential orientation is ideal for compressing the abdominal contents, increasing intra-abdominal pressure. The fibers of the transversus abdominis muscle also end in an aponeurosis, which contributes to the formation of the rectus sheath Fig.
The attachments of the transversus abdominis are demonstrated in Figure 2. Between the internal oblique and the transversus abdominis muscles is a neurovascular plane, which corresponds with a similar plane in the intercostal spaces. In both regions, the plane lies between the middle and deepest layers of muscle Fig. The neurovascular plane of the anterolateral abdominal wall contains the nerves and arteries supplying the anterolateral abdominal wall. In the anterior part of the abdominal wall, the nerves and vessels leave the neurovascular plane and lie mostly in the subcutaneous tissue.
The attachments of the rectus abdominis are demonstrated in Figure 2. The paired rectus muscles, separated by the linea alba, lie close together inferiorly. The rectus abdominis is three times as wide superiorly as inferiorly; it is broad and thin superiorly and narrow and thick inferiorly. Most of the rectus abdominis is enclosed in the rectus sheath. The rectus muscle is anchored transversely by attachment to the anterior layer of the rectus sheath at three or more tendinous intersections see Figs.
When tensed in muscular people, the areas of muscle between the tendinous intersections bulge outward. The intersections, indicated by grooves in the skin between the muscular bulges, usually occur at the level of the xiphoid process, umbilicus, and halfway between these structures. It lies anterior to the inferior part of the rectus abdominis and attaches to the anterior surface of the pubis and the anterior pubic ligament. It ends in the linea alba, which is especially thickened for a variable distance superior to the pubic symphysis.
The pyramidalis tenses the linea alba. When present, surgeons use the attachment of the pyramidalis to the linea alba as a landmark for median abdominal incision Skandalakis et al. Also found in the rectus sheath are the superior and inferior epigastric arteries and veins, lymphatic vessels, and distal portions of the thoraco-abdominal nerves abdominal portions of the anterior rami of spinal nerves T7—T The rectus sheath is formed by the decussation and interweaving of the aponeuroses of the flat abdominal muscles Fig.
The external oblique aponeurosis contributes to the anterior wall of the sheath throughout its length. The superior two thirds of the internal oblique aponeurosis splits into two layers laminae at the lateral border of the rectus abdominis; one lamina passing anterior to the muscle and the other passing posterior to it.
The anterior lamina joins the aponeurosis of the external oblique to form the anterior layer of the rectus sheath. The posterior lamina joins the aponeurosis of the transversus abdominis to form the posterior layer of the rectus sheath. Beginning approximately one third of the distance from the umbilicus to the pubic crest, the aponeuroses of the three flat muscles pass anterior to the rectus abdominis to form the anterior layer of the rectus sheath, leaving only the relatively thin transversalis fascia to cover the rectus abdominis posteriorly.
A crescentic arcuate line Fig. Throughout the length of the sheath, the fibers of the anterior and posterior layers of the sheath interlace in the anterior median line to form the complex linea alba. The posterior layer of the rectus sheath is also deficient superior to the costal margin because the transversus abdominis is continued superiorly as the transversus thoracis, which lies internal to the costal cartilages see Fig.
Hence, superior to the costal margin, the rectus abdominis lies directly on the thoracic wall Fig. The linea alba, running vertically the length of the anterior abdominal wall and separating the bilateral rectus sheaths Fig.

The fibres from the two heads cross the clavicle, and meet in the midline, fusing with the muscles of the face. Superiorly, the platysma inserts into the inferior border of the mandible. Innervation to the platysma is via the cervical branch of the facial nerve. This fascia is organised into several layers. These layers act like a shirt collar, supporting the structures and vessels of the neck.
We shall now look at the layers of the deep cervical fascia in more detail superficial to deep : Investing Layer The investing layer is the most superficial of the deep cervical fascia. It surrounds all the structures in the neck.
Where it meets the trapezius and sternocleidomastoid muscles, it splits into two, completely surrounding them. The investing fascia can be thought of as a tube; with superior, inferior, anterior and posterior attachments: Superior - attaches to the external occipital protuberance and the superior nuchal line of the skull.
Anteriorly - attaches to the hyoid bone. Inferiorly - attaches to the spine and acromion of the scapula, the clavicle, and the manubrium of the sternum. It spans between the hyoid bone superiorly and the thorax inferiorly where it fuses with the pericardium. The trachea, oesophagus , thyroid gland and infrahyoid muscles are enclosed by the pretracheal fascia. Anatomically, it can be divided into two parts: Muscular part — encloses the infrahyoid muscles. Visceral part — encloses the thyroid gland, trachea and oesophagus.
The posterior aspect of the visceral fascia is formed by contributions from the buccopharyngeal fascia a fascial covering of the pharynx. It has attachments along the antero-posterior and supero-inferior axes: Superior attachment - base of the skull. Anterior attachment - transverse processes and vertebral bodies of the vertebral column.
Posterior attachment - along the nuchal ligament of the vertebral column Inferior attachment - fusion with the endothoracic fascia of the ribcage. The anterolateral portion of prevertebral fascia forms the floor of the posterior triangle of the neck. We tend to think of relaxation as a good thing, however fascia needs to maintain some degree of tension.
This is especially true of ligaments. To maintain joint integrity, they need to provide adequate tension between bony surfaces. If a ligament is too lax, injury becomes more likely. Certain chemicals, including hormones , can influence the composition of the ligaments. An example of this is seen in the menstrual cycle , where hormones are secreted to create changes in the uterine and pelvic floor fascia. The hormones are not site-specific, however, and chemoreceptors in other ligaments of the body can be receptive to them as well.
The ligaments of the knee may be one of the areas where this happens, as a significant association between the ovulatory phase of the menstrual cycle and an increased likelihood for an anterior cruciate ligament injury has been demonstrated.
It has been suggested that manipulation of the fascia by acupuncture needles is responsible for the physical sensation of qi flowing along meridians in the body, [12] even though there is no physically verifiable anatomical or histological basis for the existence of acupuncture points or meridians.

In the era of laparoscopic surgery, one should be aware that insufflated gas usually carbon dioxide is sometimes temporarily retained within the abdomen, and may cause transient upper abdominal and shoulder pain, which may persist for about 3 days [ 611 ]. The nerve does not actually pass along this transverse plane as it inclines investing abdominal fascial planes. |
| Investing abdominal fascial planes | In this superficial dissection, the anterior layer of the rectus sheath is reflected on the left side. It can be associated to a wide range of disorders, and although it usually is an innocuous condition, it should prompt a search for the underlying aetiology, since some of its causes impose an urgent treatment. The posterior layer of the rectus sheath is also deficient superior to the costal margin because the transversus abdominis is continued superiorly as the transversus thoracis, which lies internal to the costal cartilages see Fig. A prospective, nonrandomized, multicenter evaluation of extreme lateral interbody fusion for the treatment of adult degenerative scoliosis: perioperative outcomes and complications.
