[i] The purpose of this study was to determine the prevalence
of hip abnormalities detected on 3T MRI in an active pediatric population with
no hip symptoms and to compare with hip abnormalities found in children and
adolescents who underwent an MRI for a hip-related condition. …
The average patient age
was 14.9 years for both cohorts (range 9 to 18 y) and 48% were male. In
the ASx group, incidental labral tears were found in 18%, labral/paralabral
cysts 6%, cartilage lesion 0%, subchondral cyst 0%, ligamentum teres tear 0%,
femoral fibrocystic change 0%, cam lesion 30%, acetabular bone edema 0%,
acetabular rim fracture 0%.
[ii] Sub spine impingement (SSI) is an
increasingly reported entity, symptomatically characterized by anterior groin
pain and limitations in hip-joint range of motion (ROM) brought on by a
low-lying anterior inferior iliac spine (AIIS). …
Along with limitations in ROM, it is
suggested that SSI may be correlated with irreparable labral tears, as well as
injury to the ligamentum teres [6].

[iv] Seventeen 6-week-old male New Zealand white rabbits were
randomly assigned to 3 groups: GI (n = 3) – control group, with six normal hips
(NH); GII (n = 7) – seven left instability surgery hips (ISH) and seven right
surgery sham hips (SSH); GIII (n = 7) – seven left instability surgery hips,
followed by hindlimb bandage immobilization for 3 days (ISHI) and seven right
hips without surgery (HWS). The instability surgery was performed by sectioning
the teres ligament and the sham by accessing the capsule without its section.
After 14 weeks following the induction surgery, the rabbits underwent
radiographic and computed tomographic studies and histopathological characterization
of the hip joint based on the severity of cartilage structure and chondrocyte
pathology. In the imaging assessment, the ISHI group was the only group
presenting statistically significant differences in all four parameters,
consistent with HD [Hip dysplasia] development (P < 0.05).

[vi] After removing the residual muscle and soft tissue attachment, the greater trochanter was lifted proximally to expose the hip capsule anteriorly. A “Z” incision was made in the capsule to expose the femoral head fracture site. Following ligament resection, the femoral head was reduced and stabilized using 2–3 subchondral headless Herbert screws or 4 mm cannulated screws as needed.
[vii] In addition to the
medial circumflex and lateral circumflex artery, the head of the femur also
acquires blood supply through the ligamentum teres which is a major blood
supply in childhood (4). Blood supply from the Lateral circumflex artery and
ligamentum teres begin to regress after the age of 4 until 10 years (3).

[viii] Future studies incorporating additional imaging techniques such as MRI or dynamic assessments could provide a more comprehensive understanding of hip joint pathologies including labral tear, cartilage damage, ligamentum teres tear, capsular condition, and impingement issues.

well-defined and subcircular-shaped fovea capitis.
[x] The rarity of this condition [Luxation of the
coxofemoral joint] in
equids is attributed to the deep acetabulum, reinforced by the
fibrocartilaginous acetabular rim, robust ligamentous structures (including the
round and accessory ligaments), and substantial musculature that provides
strong stabilization to the coxofemoral joint [2, 10].

[xi] After
visualization of the external rotators of the hip, slide osteotomy of the
greater trochanter and its mobilization within the required visualization of
the hip joint capsule with its subsequent Z-shaped dissection were performed.
After intersection of the proper ligament of the femoral head, dislocation was
performed with subsequent separation of the periosteal-capsular-muscular flap
containing the main source of blood supply to the femoral head - the branch of
a. circumflexa femoris medialis. The next stage was segmental resection of the
femoral head (Fig. 1).

[xiii] Abstract
Case: A 39-year-old woman who was involved in a motor
vehicle collision sustained a right hip posterior wall acetabular
fracture-dislocation. Subsequent
dislocation was noted at the 4-week point with gross instability and
heterotopic ossification. She underwent a hip containment technique using a
transfemoral neck tunnel through the quadrilateral surface and FiberTape. At
1-year postoperatively, she reported improvement in mobility without evidence
of repeat dislocation.
Conclusion: This technique can be used for unstable
hip sockets with a small posterior wall acetabular fracture to maintain hip
stability. This is the first
reported technique using an open intrapelvic approach to stabilize the hip.
…
In less severe nontraumatic cases, microinstability at the hip may potentially
be improved with ligamentum teres reconstruction 2 , 3 .
The ligamentum teres has also been described as the secondary stabilizer of the hip joint 5 .
[xiv] For short
segmental defects, the ligamentum capitis femoris (ligamentum teres) can be
used to reconstruct the labrum.
The ligamentum teres is cut by a pair of curved parametrium scissors as close as possible to the teardrop to obtain a graft as long as possible.
[xv] These hips
commonly have an aspheric femoral head, intra-articular abnormalities (labrum,
articular cartilage, and ligamentum teres), intra-articular impingement,
extra-articular impingement, and instability from secondary acetabular dysplasia.
[xvi] By raising the hook and simultaneous external rotation, subluxation is achieved, which facilitates the introduction of uterine scissors and allows the tensioned ligamentum teres to be cut.
[xvii] Structures such as the labrum, the ligamentum capitis femoris, and the joint capsule are usually not considered although they can contribute substantially to hip ROM.

[xix] This study developed a minimally
invasive technique for stabilization of coxofemoral luxation, guided by
radiographic images, in dog cadavers, being, to the authors’ knowledge, its
first description in literature. The procedure started by defining positionings
of the limb, aiming to guide the introduction of the guide pin (GP) and planning
the technique. Thereafter, the GP was percutaneously introduced into the
greater trochanter of the femur, until it crossed the acetabular far cortical.
After its implantation, a cannulated drill (CD) was inserted, and drilled until
it crossed the acetabular far cortical. The GP was removed, and a toggle pin
was introduced and accommodated in the acetabular far cortical.
The toggle pin (which measured 10.0 mm in length and 2.0 mm in diameter)
had a central hole through which a suture was passed (1-poliglecaprone-25, just
to simulate the technique) (Figure 4B). The toggle pin and suture were inserted
into the CD through an introducer and were accommodated on the medial surface
of the acetabular far cortical (Figure 3I, Figure 4A and Figure 4D).
After passage and proper positioning of the toggle pin, the CD was removed and a metallic button (Figure 4A), with holes through which the two ends of the suture had been passed, was fixed on the lateral surface of the greater trochanter of the femur (Figure 5E). Radiographic images were performed to visualize the positioning of the implants and determine the end of the procedure, in P1 and P2 (Figure 5F).

[xx] The surgical
management of hip luxation consists in various hip stabilization techniques,
including capsulorrhaphy, extra-articular iliofemoral suture (3) secured with
anchors (4) and intra-articular replacement of the femoral head ligament with a
synthetic ligament secured by toggle pins (5).
A first femoral tunnel was drilled from the distal base of the great
trochanter to the fovea capitis. A second femoral tunnel was drilled
perpendicularly to the first one in a more distal position. A third tunnel was
drilled through the acetabulum on the round ligament footprint. The cortical
button of the ligament was passed through the acetabular tunnel and securely
positioned on the medial aspect of the acetabulum. The ligament was then passed
in the first femoral tunnel, and the hip was reduced. Then the implant was
passed through the second femoral tunnel, tensioned, and secured by an
interference screw.
