Nerve Deltoid Injury

The medial side of ankle is very interesting because it has the important structure; bones, deltoid ligament and tarsal tunnel which composes of posterior tibial artery, posterior tibial nerve and their branches. The injuries at ankle have numerus injuries of these structures such as medial malleolus fracture, ligament sprain, ligament tear, nerve entrapment, and impair blood circular. For ankle sprains, deltoid ligament injury may occur increase to 18% (Lin et al. , 2006). Chronic instability and disability may be caused from ankle injuries in 20-40% (Renstrom, 1994 ของ estudio2012). Then, the nerve entrapment is one of the causes of heel pain [ 2 TNE] and found that 24 % of older adults (≥ 45 years) have frequent foot pain [ 1 TNE ]. The peripheral nerve dysfunction causes of impaired circulation and nerve compression 10-18 Mary Claire Manske2016. Then, the nerve compression results from arterial branches distribution and location in these cases10,14,19-21 Mary Claire Manske2016. The knowledge of arterial supplying of peripheral nerve may provide clinical insight tarsal tunnel syndrome ( Mary Claire …show more content…
Currently, the arthroscopic technique becomes important tool for diagnosis and therapy for surgeon (1Mehdi2012) because it allows direct intra-articular pathology visualization, faster rehabilitation, lower morbidity and better cosmetic results when compared with conventional open surgical technique (iii arthro2014). The knowledge of anatomy is particularly important in arthroscopic technique because it can prevent or decrease the risk complications in arthroscopic technique (1golano2006) including external fixation technique at calcaneus and talus because these knowledges get understanding about safe zone for pin insertion (การศึกษา safe zone ทั้งหมด). Moreover, the lack of anatomical understanding cause of failure treatment (the failed
