Sustentaculum Tali

At the upper and forepart of the average surface of the calcaneus is a level distinction, the sustentaculum tali, which offers a connection to an error of the ligament of the Tibialis back. This prominence is sunken above, and verbalizes with the center calcaneal articular surface of the bone; beneath, it is scored for the ligament of the Flexor hallucis longus; its foremost edge offers a connection to the plantar calcaneonavicular tendon, and its average, to a piece of the deltoid tendon of the lower leg joint.

 

sustentaculum tali

 

The sustentaculum tali is an even retire that emerges from the anteromedial segment of the calcaneus. The predominant surface is inward and expresses with the center calcaneal surface of the bone. The substandard surface has a depression for the ligament of flexor hallucis longus.

 

A few ligamentous structures append to the sustentaculum tali:

  1. Plantar calcaneonavicular tendon (foremost surface)
  2. Deltoid tendon (average surface)
  3. Average talocalcaneal tendon

 

Related pathology

The sustentaculum tali are normally associated with instances of tarsal alliance, particularly talocalcaneal alliance and subtalar alliance. In instances of talocalcaneal alliance, the entire C-sign can be seen on a parallel radiograph where there is spanning between the bone superiorly and the back part of the sustentaculum tali poorly.

 

Osteitis of the Sustentaculum Tali

The sustentaculum bone is on the plantaromedial part of the calcaneus. Wounds including the average part of the sell frequently include the sustentaculum bone and nearby tarsal sheath. Damage, as a rule, happens from direct injury, most ordinarily from a kick wound. Weakness is regularly extreme. The finding can be troublesome as a result of the extreme delicate tissue swelling that goes with this damage, particularly when intense.

Albeit bizarre, there can be correspondence of the site of disease or discontinuity of the sustentaculum bone with the tarsocrural joint. Radiographic examination ought to incorporate dorsomedial-plantarolateral diagonal, dorsoplantar, and plantar proximal-plantar distal pictures. Ultrasonography is helpful to survey the profound computerized flexor ligament (DDFT) and tarsal sheath. Contamination of the tarsal sheath because of sustentaculum bone discontinuity or lysis requires careful curettage of the sustentaculum bone and lavage and flushing of the tarsal sheath.

Ponies with hard anomalies in the tarsal furrow of the sustentaculum bone can be extremely faltering, even without contamination, in light of movement of the DDFT against the roughened bone, which results in serious tendonitis. The tarsal retinaculum can wind up constrictive if the ligament is excited and swollen, which creates additional ligament harm and torment. The medical procedure with the steed under general anesthesia is prescribed to transect the tarsal retinaculum, investigate and curette necrotic bone including the sustentaculum bone, and deplete and flush the tarsal sheath. The tarsal score ought to be smoothed with a curette to evade scraped area to the DDFT after the medical procedure. Endoscopic examination of the tarsal sheath might be troublesome in ponies with extreme swelling from the associative disease.

In steeds with gentle swelling, with waste limited to the locale of the sustentaculum bone, and without generous tarsal tenosynovitis, a little cut ought to be made specifically over the pieces. The parts ought to be evacuated and the site curetted; the entry point is shut principally. In these steeds, visualization for future soundness is ideal.
