Therefore, the purpose of the present research was to study its morphology to improve our understanding of its structure and potential variation. Methods: Ten adult cadavers (four males and six females) underwent dissection of the left and right hip joints to observe the morphology and location of the zona orbicularis. A digital caliper was used to measure the length and width of the zona orbic- ularis. Results: We found a zona orbicularis on all sides and that when present anteriorly, many of the inferior fibers of the zona orbic- ularis were confluent with the fibers of the iliofemoral ligament. The mean length for right sides was 35.95 mm and the mean length for left sides was 43.93 mm. The mean width for right sides was 3.74 mm and the mean width for left sides was 4.4 mm.

Paraskevas Department of Anatomy, Medical School, Aristotle University of Thessaloniki, Greece [Received 24 January 2011; Accepted 22 March 2011] A high concern exists among physicians about surgically important ligaments such as cruciate and collateral ligaments of the knee, patellar ligament, tibiofibular syndesmosis, collateral ligaments of the ankle, and coracoclavicular ligament. However, the classification of the ligaments is insufficient in the literature, due to their origin from connective tissue. A new classification is proposed, based on various parameters such as the macroscopic and microscopic features, the function and the nature of their attachment areas. (Folia Morphol 2011; 70, 2: 61–67) Key words: ligaments, classification, Nomina Anatomica INTRODUCTION connective tissue surrounding neurovascular bundles There was always some confusion concerning the or ducts as “true ligaments” [4]. classification of ligaments of the human body, presu- The “false ligaments”, could be subdivided in the mably due to their origin from the connective tissue following categories: that is considered a low quality tissue compared to oth- a) Splachnic ligaments, which are further subdivid- ers.

For these reasons there is an “pericardiac” (e.g. sternopericardial ligaments), absence of a well-designated classification system that “pleural” (e.g. suprapleural membrane), and subdivides the ligaments into subgroups according to “pure splachnic ligaments” (e.g.

Hip Joint Capsular Anatomy, Mechanics, and Surgical Management

Geoffrey Ng, PhD, Jonathan R.T. Jeffers, PhD, and Paul E. Beaule,´ MD, FRCSC Investigation performed at the Imperial College London, London, United Kingdom, and the Division of Orthopaedic Surgery, University of Ottawa, Ottawa, Ontario, Canada ä Hip joint capsular ligaments (iliofemoral, ischiofemoral, and pubofemoral) play a predominant role in functional mobility and joint stability. ä The zona orbicularis resists joint distraction (during neutral positions), and its aperture mechanism stabilizes the hip from adverse edge-loading (during extreme hip ﬂexion-extension). ä To preserve joint function and stability, it is important to minimize capsulotomy size and avoid disrupting the zona orbicularis, preserve the femoral head size and neck length, and only repair when or as necessary without altering capsular tensions. ä It is not fully understood what the role of capsular tightness is in patients who have cam femoroacetabular impingement and if partial capsular release could be beneﬁcial and/or therapeutic. ä During arthroplasty surgery, a femoral head implant that is nearly equivalent to the native head size with an optimal neck-length offset can optimize capsular tension and decrease dislocation risk where an intact posterior hip capsule plays a critical role in maintaining hip stability. Hip joint capsular ligaments serve a fundamental role in bal- functional anatomy and material characteristics of the hip ancing functional mobility and joint stability.

It avails both mobility and stability. As the structural linkage between the axial skeleton and lower limbs, it plays a pivotal role in transmitting forces from the ground up and carrying forces from the trunk, head, neck and upper limbs down. This Article reviews the embryology, anatomy and biomechanics of the hip to give a hand in diagnosis, evaluation and treatment of hip disorders. Discussion: Exact knowledge about development, anatomy and biomechanics of hip joint has been a topic of interest and debate in literature dating back to at least middle of 18th century, as Hip joint is liable for several number of pediatric and adult disorders. The proper acting of the hip counts on the normal development and congruence of the articular surfaces of the femoral head (ball) and the acetabulum (socket). It withstands enormous loads from muscular, gravitational and joint reaction forces inherent in weight bearing. Conclusion: The clinician must be familiar with the normal embryological, anatomical and biomechanical features of the hip joint.

Iliofemoral Ligament
LOWER LIMB Hip Joint: forms the connection between the lower limb & the pelvic girdle Classification: Ball and socket synovial joint Freedom: 3 degree, multiaxial Movement: Flexion, extension, abduction, adduction, medial and lateral rotation and circumduction. Plane: Sagittal (F & E), Frontal (Abd & Add), Transverse (M & L rotation) Axis: Frontal (F & E), Saggital (Abd & Add), Longitudinal (M & L rotation) Static stabiliser: Joint capsule and their ligaments- Pubofemoral ligament, iliofemoral ligament, ischiofemoral ligaments and the actebular labrum (stabilise head of femur into acetabulum) Function: It is designed for stability over a wide range of movement. When standing, the entire weight of the upper body is transmitted through the hip bones to the heads & neck of the femora. Pubofemoral ligament: Attachment: arises from the obturator crest of the pubic bone and passes laterally and inferiorly to merge with the fibrous layer of the joint capsule (textbook) It is the thickened part of the hip joint capsule which extends from the superior ramus of the pubis to the intertrochanteric line of the femur (app) Function: It tightens during both extension and abduction of the hip joint. The pubofemoral ligament prevents overabduction of the hip joint. Stabilizes the hip joint and limits extension and lateral rotation of the hip. Iliofemoral ligament: Attachment: attaches to the anterior inferior iliac spine and the acetabular rim proximally and the intertrochanteric line distally Function: Said to be the body’s strongest ligament, the iliofemoral ligament specifically prevents hyperextension of the hip joint during standing by screwing the femoral head into the acetabulum and it is the main ligament that reinforces and strengthen the joint.
