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

Tiktaalik roseae

TIKTAALIK ROSEAE The first truly tetrapod animal (Limbed tetrapods) is recognized as the lobe-finned fish Tiktaalik roseae (clade Elpistostegalia), discovered in rocks aged about 375 Ma (2006DaeschlerEB_JenkinsJrFA; 2008ShubinN; 2017ShubinN). Discoveries in recent years have allowed us to place the taxa of early tetrapodomorphs in the following order: Tinirau, Eusthenopteron, Megalichthys, Panderichthys, Qikiqtania, Tiktaalik, Elpistostege, Parmastega, Ventastega, Acanthostega, Elginerpeton, Ymeria, Ichthyostega (2022StewartTA_ShubinNH). The closest ancestor of Tiktaalik roseae, the fragments of the skeleton of which are relatively well preserved, is Panderichthys.

The shape of the skeleton of the pectoral fin and shoulder girdle suggests that Panderichthys rhombolepis "walked" (2006AhlbergPE_ClackJA). At the very least...

Homo floresiensis

HOMO FLORESIENSIS Homo floresiensis lived on the island of Flores (Indonesia) 190-50 Kya (2016SutiknaT_RobertsRG). The ancestor of this species is «suspected» to be the Asian subtype Homo erectus, which arrived from the mainland about 800 Kya (2009LyrasGA_DeVosJ). The anatomy of Homo floresiensis is less similar to Homo habilis (2008Gordon_WoodB). Homo floresiensis Author: Cicero Moraes et al. (Arc-Team) ; source: wikimedia.org collection (license CC BY 4.0, no changes). Among the discovered remains of a female Homo floresiensis ( humanorigins . si . edu ) there is a relatively well-preserved left pelvic bone (LB1/7). It has a « typically human » acetabulum (2009JungersWL_DjubiantonoT:Fig.3). The acetabulum has a complete fusion of the three bones that form it and is not hypoplastic (2012BrownP:Fig.4). The acetabular fossa is rounded and deep, continuing downwards and forwards as a wide acetabular notch. This area is the site of attachment and func...

Catalog. Arthroscopic reconstruction

Introduction Currently, ligamentum capitis femoris (LCF) reconstruction using arthroscopic technologies is considered promising. According to the literature available to us, the first such operation was performed by Marc J. Philippon, which he first reported on in May 2006 (2006PhilipponMJ). Until now, reconstruction of LCF using minimally invasive technologies has not yet become widespread. The long-term results of arthroscopic LCF repair are still uncertain due to insufficient number of surgical procedures performed and short follow-up period (2014O'DonnellJM_SinghPJ).
