The gastrocnemius, soleus, and plantaris: They are the primary plantar flexors that combine to form the
Achilles tendon
. The Achilles tendon attaches to the calcaneal tubercle.
What muscle inserts into the calcaneal tuberosity?
Muscle Direction Attachment | Gastrocnemius Insertion Calcaneal tubercle through the achilles tendon | Soleus Insertion Calcaneal tubercle through the achilles tendon | Plantaris Insertion Calcaneal tubercle either directly or through the achilles tendon | Extensor digitorum brevis Origin Dorsal side of calcaneus |

What connects to the calcaneus?
Calcaneocuboid ligament
– the ligament that connects the calcaneus and the tarsal bones and helps the plantar fascia support the arch of the foot.
Does the Achilles tendon attach to the calcaneal tuberosity?
The Achilles tendon connects muscle to bone, like other tendons, and is located at the back of the lower leg. The Achilles tendon connects
the gastrocnemius and soleus muscles
to the calcaneal tuberosity on the calcaneus (heel bone).
What inserts on the Sustentaculum Tali?
- plantar calcaneonavicular ligament (anterior surface)
- deltoid ligament (medial surface)
- medial talocalcaneal ligament.
Which type of bone is the calcaneus comprised of?
The calcaneus is
an irregular bone, cuboid
in shape whose superior surface can be divided into three areas – the posterior, middle and anterior aspects.
What kind of bone is calcaneus?
The calcaneus (heel bone) is
the largest of the tarsal bones in the foot
. It lies at the back of the foot (hindfoot) below the three bones that make up the ankle joint. These three bones are the: Tibia — shinbone.
How do you side the calcaneus?
1. Siding the calcaneus based on its overall shape: If the overall calcaneal form is relatively well-preserved, but the articular facets themselves have degraded or have been caked with intractable sediment, the easiest way to side the bone is,
somewhat counter-intuitively, to flip it over
.
How strong is the calcaneus?
The calcaneus/Achilles tendon is the strongest tendon in the body. The load during walking is estimated to be 2.5 times the body weight, and
running may increase this up to 6–12 times
(Komi et al. 1992; Merskey et al. 1994).
How do you remember calcaneus?
Calcaneus and Cuboid
The 2 words in the mnemonic we have not yet used are
“covers” and “covers”
. This will help you remember the final 2 tarsal bones as they both start with the letter “C”. The first bone is the calcaneus which forms the heel of the foot and is located in the proximal tarsal row with the talus.
Can Achilles tendon heal on its own?
A partially torn Achilles tendon can often heal on its own
. The following steps can help speed up the healing process: Avoid putting weight on your leg. Ice your tendon.
Will ankle brace help Achilles tendonitis?
Can an ankle brace help with Achilles tendonitis? The correct ankle brace will definitely
help with the pain and swelling associated with
Achilles tendonitis and also allow you to regain mobility while your tendon heals.
How long does it take for a strained Achilles tendon to heal?
Depending on the type of work, some people need several weeks off work after an Achilles tendon tear (rupture); the time taken to return to sport is between 4 and 12 months. Generally, the outlook is good. However, the tendon does take time to heal, usually
about six to eight weeks
.
Which tarsal bone is the point of attachment of the calf muscle?
The posterior aspect of the
calcaneus
is marked by calcaneal tuberosity, to which the Achilles tendon attaches. Fig 2 – The tarsal bones of the foot.
Why does my sustentaculum tali hurt?
Osteitis of the Sustentaculum Tali
Injury usually occurs from
direct trauma
, most commonly from a kick wound. Lameness is often severe. Diagnosis can be difficult because of the severe soft tissue swelling that accompanies this injury, especially when acute.
Is sustentaculum tali medial or lateral?
The sustentaculum tali forms the floor of middle facet, and the anterior facet articulates with the head of the talus, and sits
lateral
and congruent to the middle facet. In some people the middle and anterior facets are joined giving just one articulation.
