The anterior
talofibular ligament (ATFL) is commonly injured and may result in ankle
instability. Good results from ATFL reconstruction have been reported;
however complications and movement restrictions have also been observed. ATFL
differences have been reported; however details of its precise bony
attachment are lacking. This study provides a detailed morphology of the ATFL
with respect to surgical and clinical applications. ATFL morphology, number
of bands and the exact insertion points were studied in 50 formaldehyde
embalmed feet. ATFL length was measured in different joint positions to
assess its functional role: ATFL length varied from 18.81 mm in dorsiflexion
to 21.06 mm in plantarflexion: mid-length width and thickness were 4.97 mm
and 1.01 mm respectively. The bony attachment lengths were also measured:
mean proximal and distal bony attachment lengths were 4.68 mm and 3.1 mm
respectively, while 13.04 mm had no bony attachment. One (22.9%), two (56.3%)
and three (20.8%) band morphologies were observed originating 10.37 mm anterosuperior
to the lateral malleolar tip and inserting 3.92 mm anterior to the anterior
lateral malleolar line (ALML). Detailed morphology of the ATFL may help in
restoring injured ATFL function by appropriate ligament reconstruction, as
well as aid the understanding of the mechanism of ligament injury.

The anatomy of the superficial component of the deltoid ligament of the
ankle
|
ملخص المشاركة:
|
The superficial
deltoid ligament, consisting of tibionavicular (TNL), tibiospring (TSL),
tibiocalcaneal (TCL) and superficial tibiotalar (STTL) parts, was
investigated in 54 formalin embalmed feet (27 right, 27 left; 19 male, 35
female). All parts were observed in all specimens, except STLL which was
present in 92.4%. The TNL originates from the anterior border and/or medial
surface of the anterior colliculus inserting into the dorsomedial surface of
the navicular and talus: its length, width and thickness were 34.9mm, 8.3mm
and 0.7mm. The TSL extends from the anterior border and/or medial surface of
the anterior colliculus to the spring ligament and/or sustenaculum tali: its
length width and thickness were 30.9mm, 6.1mm and 0.8mm. The TCL has various
proximal attachments including medial surface of the anterior and posterior
colliculi and superior to the intercollicular groove inserting into either
the sustenaculum tali, spring ligament, talus or posteromedial talar
tubercle: its length, width and thickness were 29.6mm, 6.3mm and 1.0mm. The
STTL attached superior to the intercollicular groove, anterior to the medial
surfaces of the anterior and posterior colliculi inserting into the
sustenaculum tali and/or talus and posteromedial talar tubercle: its length,
width and thickness were 23.2mm, 5.4mm and 1.00mm.

The deep posterior tibiotalar ligament (PTTL): a morphological study
|
ملخص المشاركة:
|
Deltoid ligament injury may result
from ankle fractures, sports injury and traffic accidents leading to medial
ankle instability and chronic pain. The deep part of the deltoid complex, the
posterior (PTTL) and anterior (ATTL) tibiotalar ligaments, is the main ankle
joint stabiliser preventing external talar rotation and lateral talar shift.
In an examination of 52 formalin embalmed feet (26 right, 26 left; 33 female,
19 male) the PTTL had one (5.8%), two (44.2%) or three (50%) bands. There
were no significant relationships between the number of the bands and gender
(r=0.11) or side (r=0.16). The PTTL extends between the anterior colliculus
posterior part and the posterior colliculus anterior part filling the
intercollicular groove of the medial malleolus. Its distal insertion is to
the medial talar surface distal to the articular surface, varying from78.2%
anterosuperior, 20.9% posterosuperior and 0.9% superior to the talar
posteromedial tubercle (PMT). Distances and angles between the insertion points
and PMT were 10.5 mm and 50.5° (anterosuperior), 7.5 mm and 101.5°
(posterosuperior), 8.3 mm and 90° (superior). The mean length in neutral,
midwidth and thickness were 15.3 mm, 9.4 mm and 1.4 mm. 54.9% of PTTL length
had no bony attachment while 26% attached to the talus.

Morphology of the calcaneofibular
ligament: the influence of joint position
|
عنوان المشاركة:
|
The
calcaneofibular ligament (CFL) may be involved in lateral sprain injuries;
however ankle instability and limitation of movement have been reported
following surgical reconstruction protocols. The CFL was investigated in 45
feet from 23 formalin embalmed cadavers (14 female, 9 male: 23 right , 22
left).It originated from the anterior border of the lateral malleolus, anterior
to the tip in 88.6% and extending to the tip in 11.4%: the distance and angle
between the tip and midpoint of the proximal attachment were 7.3mm and 50°.
The CFL inserted distally posterosuperior (81.1%) or posteroinferior (18.9%)
to the fibular tubercle on the lateral surface of the calcaneus. The distance
and angle between the fibular tubercle and the midpoint of the distal
insertion were 16.4mm and 15° (posterosuperior insertion) and 20.1mm and 12°
(posteroinferior insertion). The mean lengths were 29.4, 30.6, 27.8, 28.9 and
30.2 mm in neutral and passive dorsiflexion, plantarflexion, inversion and
eversion respectively. The width and
thickness at the midpoint were 4.6mm and 1.6mm respectively. 28.68% of CFL length was attached distally
to the calcaneus; 62.47% had no bony attachment. A better understanding of
CFL morphology will aid diagnosis, mechanisms of injury and treatment,
especially surgical reconstruction.

Anatomy of the anterior talofibular ligament (ATFL)
|
ملخص المشاركة:
|
The morphology and variations of the anterior talofibular ligament
(ATFL) was investigated in 34 feet from 17 formalin embalmed cadavers (11
female & 6 male). The ATFL originates from the anterior border of the
lateral malleolus and runs anteromedially to the talus. One, two and three
band forms of the ligament were observed in 25.8%, 61.3% and 12.9% of the
specimens respectively. The mean length the various bands with the ankle
joint in neutral, dorsiflexion and plantarflexion respectively were: superior
band 21.27 mm, 20.24 mm and 21.96 mm; middle band 15.97 mm, 16.96 mm and
19.82 mm; and inferior band 17.75 mm, 17.83 mm and 18.69 mm. The width of
each band at the proximal attachment, at the midpoint and at the distal
attachment respectively were: superior band 4.88 mm, 4.71 mm and 3.98 mm;
middle band 2.04 mm, 2.1 mm and 1.99 mm; and inferior band 4.33 mm, 4.23 mm
and 3.29 mm. The thickness of the superior band was 1.25 mm, of the middle
0.93 mm and of the inferior 0.89 mm.
