[i] … presents a Pipkin type II fracture with
the femoral head fragment attached to the ligament of head of femur (ligamentum
teres) (Fig. 1). …
Reason for an irreducible joint may
be an avulsed ligament of the head of the femur, …
[ii] Labral tears, chondral loss, abnormal
ligamentum teres, anterior capsule thinning, iliocapsularis to rectus femoris
ratio, posterior crescent sign, cliff sign, and femoro-epiphyseal acetabular
roof (FEAR) index were not associated with microinstabillity.
The function and significance of the
ligamentum teres are debated; however, it is increasingly recognized as a
secondary stabilizer of the hip joint, and biomechanical and surgical studies
have suggested ligamentum teres injuries are associated with joint instability
[40,
41].
While complete tears of the ligamentum teres are relatively rare, with the prevalence
of up to 1.5% reported at arthroscopy [42], partial tears and
other abnormalities such as hyperplasia are commonly reported at arthroscopy.
Abnormal ligamentum teres on MR was not associated with hip microinstability in
this study.
However, the other imaging findings
on MR showed only fair or moderate agreement, except for abnormal ligamentum
teres which showed no agreement, when assessed by experienced musculoskeletal
radiologists. This is consistent with the published literature that has documented
that many of these findings can be challenging to accurately detect on MR with
limited or even poor reliability; diagnosis of ligamentum teres tear,
especially chronic and partial tears, may be challenging on MR with poor
sensitivity and specificity [24, 50, 51].

[iii] A complete diagnostic hip arthroscopy requires traction, especially for a comprehensive inspection of the direct weight-bearing cartilage, acetabular fossa, and ligamentum teres. Therefore, arthroscopy without traction was not effective in diagnosing and treating hip central compartment diseases such as FAI, acetabular cartilage injury, and loose bodies in the central compartment.
[iv] Wang et
al. developed a juvenile rabbit model by disrupting the femoral round ligament [6].
Currently, many scholars predominantly use a piglet model of ischemic necrosis,
which is established by placing a non-absorbable ligature tightly around the
femoral neck to cut off the blood supply to the capital femoral epiphysis [7,37].
Due to the limitations of space, large-scale rearing of piglets is not
feasible; therefore, we established a Perthes disease model using rabbits.
Similar to the piglet model of Perthes disease, we cut the ligament of the
femoral head and tightly ligated the base of the femoral neck with non-absorbable
sutures. This method successfully created a rabbit model of Perthes disease.
The femoral head was
dislocated, and the Ligamentum teres was cut, severing the blood supply. Using
a curved clamp, non-absorbable sutures were placed around the femoral neck, severing
the vascular supply. The hip was then reduced, and the wound was sutured.

[vi] Flexion, adduction, and internal rotation of the leg in
the supine position causing pelvic pain can indicate a premature osseous
abutment (CAM) deformity. A supine flexion, adduction, internal rotation test
can be used to determine internal hip impingement. The FABERS (flexion,
abduction, and external rotation) can be used to screen the ligament of teres
function, femoral anteversion, SI joint or some pubofemoral ligament
contribution.
[vii] Upon completion of the imaging assessment, the joint capsule was incised and the round ligament was severed to expose the articular surface.
Our study confirmed that
the novel rabbit FAI model created acetabular over coverage and produced
articular cartilage injury at the impingement zone.

[ix] Other differences with MAU-Pv-PH-453 are the presence of a trochanteric shelf on the proximal and lateral surface of the bone, a posterior trochanter on the proximal posterolateral surface, and a groove for the ligamentum capitis femoris ...
[x] According to the findings detected during intraoperative OR (open reduction), the acetabulum was shallow in 52 (65.82%) hips. The teres ligament was intact and thickened in 62 (78.48%) hips. The ligamentum teres was ruptured in four (5.06%) and thinned in 13 (16.45%) hips. The limbus was inverted in 12 (15.18%) hips, everted in 46 (58.22%) hips, and normal in 21 (26.58%) hips. The posterior wall was inadequate in 18 (22.78%) hips. All patients treated with OR underwent iliopsoas tenotomy. They also all underwent careful capsulorrhaphy. Partial excision was performed in some of the hypertrophic capsules. If stabilization was deemed sufficient after OR, no additional intervention was performed.
[xi] The major branch group of the medial circumflex femoral artery, the retinacular artery, connects with the artery of the ligamentum teres within the femoral head, forming epiphyseal and metaphyseal arterial networks.
[xii] A 32-year-old male presented with an acute painful left hip region for the last 2 months following a minor misstep during hip-hop routine. The pain increases with weight-bearing and gets relieved by rest and pain medications. Radiographs were unremarkable with no underlying bony abnormality. Magnetic resonance imaging (MRI) revealed no bony injury except hyperintensity or edema surrounding the LT with the contralateral side unaffected [Figure 1]. Apart from the injury, there was also the anatomical difference between both the fovea capitis with the affected left side being deep and notched as compared to the right side.
On the basis of clinical and radiological findings, diagnosis of LT
injury or sprain was made. A period of conservative methods including rest to
the extremity and crutch use was advised along with pain medication on as and
when required basis. After a period of 5 weeks, clinical improvement was noted,
and with another 2 weeks of protected ambulation, the patient was having
painless ambulation and range of motion.
...
This briefcase snippet is described here for the recognition of uncommon
LT injury by appropriate investigation and clinical correlation. We advocate
suspecting and keeping this injury as an uncommon differential diagnosis in
cases with unexplained hip pain following the injury related with sports or
recreational activity. Appropriate diagnosis results in optimal management, and
the use of MRI helps in identifying subtle injuries of the ligamentous origin.
[xiii] Conoryctes
has a continuous lunate surface that is subequal in width as seen in
Stylinodon. There is a foramen in the pubic area of the acetabular fossa in
Stylinodon where the ligamentum teres attached; Conoryctes lacks this foramen.
[xiv] Although hip
arthroscopy was controversial until recently, advancements in tools and
surgical techniques have made it an increasingly common method in orthopedics.
This procedure allows for detailed visualization of the cartilage surfaces of
the femur and acetabular labrum, and provides a view of the ligamentum teres,
synovial membrane, and peri-trochanteric spaces.
[xv] CONCLUSION(S)
A detailed study of the morphology and morphometry of
the FCF (Fovea Capitis Femoris) in the West Bengal population revealed that the
most common shape of the fovea is oval, and its most frequent position is in
the posterior-inferior quadrant of the femoral head. The mean values for the
transverse diameter, vertical diameter, and DF were found to be 1.53±0.367 cm,
1.28±0.303 cm, and 0.304±0.141 cm, respectively. This data will contribute to
the existing knowledge of anatomists, radiologists, and surgeons and may be
useful in the planning and execution of surgical interventions involving the
proximal end of the femur.
