Localization of LCF Pathology

Version: 20240418

Localization of LCF pathology is classified based on the anatomical-topographical principle. It is assumed that the LCF does not end near the attachment site but penetrates into it.

LOCALIZATION OF LCF PATHOLOGY

1. Middle part

2. Distal end

3. Proximal end

4. Distal attachment area

5. Proximal attachment area

6. Medial surface

7. Lateral surface

8. Anterior edge

9. Posterior edge

10. Transsynovial

11. Subsynovial

12. Total Lesion

The medial surface faces the bottom of the acetabulum. The lateral surface faces the femoral head. Transsynovial pathology implies changes including or only involving the synovial membrane. Subsynovial pathology is localized exclusively beneath the synovial membrane of LCF. Pathology can involve multiple parts of LCF, for example, damage to the distal end and proximal attachment area in a transacetabular fracture.

The distal part of LCF attaches directly to the bone of fovea capitis femoris. Along the periphery of the fovea capitis femoris, LCF attaches to the articular cartilage (approximately 3 mm away).

LOCALIZATION OF PATHOLOGY IN THE DISTAL ATTACHMENT AREA OF LCF

1. Bony Attachment Area

2. Cartilaginous Attachment Area

The proximal part of LCF attaches to several anatomical structures and their zones.

LOCALIZATION OF PATHOLOGY IN THE PROXIMAL ATTACHMENT AREA OF LCF

1. Bottom of the acetabular fossa

2. Anterior part of the semilunar surface

3. Posterior part of the semilunar surface

4. Bottom of the acetabular notch

5. Transverse acetabular ligament

6. Obturator membrane

7. Periosteum of the ischium

8. Periosteum of the pubic bone

9. Joint capsule

In the distal part, we identify three portions of the LCF stroma.

LOCALIZATION OF PATHOLOGY IN THE DISTAL PART OF LCF

1. Medial

2. Anterior

3. Posterior

In the middle part of the LCF, the above portions begin to be divided into several parts (subportions). Pathology may affect one or more portions.

LOCALIZATION OF PATHOLOGY IN THE PROXIMAL PART OF LCF

1. Portion of the bottom of the acetabulum fossa

2. Portion of the bottom of the acetabular notch

3. Anterior portion of the semilunar surface

4. Posterior portion of the semilunar surface

5. Portion of the transverse acetabular ligament

6. Portion of the obturator membrane

7. Portion of ischium

8. Portion of pubic bone

General Classification of LCF Pathology Version : 20240420 Annotation Analysis of literature data and our own morphological observations allowed us to propose a General Classification of LCF Pathology. Introduction In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. L.I. Gaevskaya distinguished three types of LCF: 1) long and thick (length 41–51 mm, thickness 5 mm), 2) short and thin (length 10–20 mm, thickness 1 mm), 3) long and of small thickness (length 43–45 mm, with a thickness of 3 mm, and length 28–30 mm with a thickness of 4–5 mm) (1954 ГаевскаяЛИ ). V.V. Kovanov, A.A. Travin identified three varieties of histological structure of LCF: 1) with a predominance of loose connective tissue; 2) with a predominance of dense connective tissue; 3) with a uniform distribution of loose and dense connective tissue ( 1963 КовановВВ _ ТравинАА ). The development of arthroscopic surgery has made it possible to i...

1857HyrtlJ

The author discusses the anatomy, structure, and role of the ligamentum capitis femoris (LCF). Based on his own research, Josef Hyrtl asserts that the vessels of the LCF do not participate in supplying blood to the femoral head. The author highlights the high strength of the LCF and changes in congenital dislocations. Apparently, this work was the first to suggest that the LCF serves as a conductor of inflammatory processes and a cause of coxalgia. Hyrtl J.

344-411Rufinus Aquileiensis

A fragment of the manuscript of the translation of Josephus Flavius' Antiquities of the Jews ( Ἰουδαϊκὴ ἀρχαιολογία / De antiquitate iudaica) into Latin by Rufinus Aquileiensis. The translator worked approximately between 344 and 411 in the Roman Empire. His work was rewritten between 1150 and 1199 in Northern France. In Josephus's translation of Antiquities of the Jews, ligamentum capitis femoris (LCF) is referred to as «neruum». The selected fragment deals with the LCF of an animal and discusses a biblical episode of its damage in a human. See our commentary at the link: 344-411Rufinus Aquileiensis [Rus].
