    (SOC CHILENA ANATOMIA, 2016-01-01) Cinar, Ugur; Halezeroglu, Semih; Okur, Erdal; Inanici, Mehmet Akif; Kayaoglu, Semra
    The purpose of this study was to investigate the average tracheal length and number of the tracheal cartilages in Turkish people, with emphasis on the relationships to body height and sex. A hundred fresh human cadaver tracheas were harvested from 75 males and 25 females. Age, sex and body height of cadavers were recorded. All the neck and intrathoracic structures were removed. The tracheal length was measured between the subcricoid level to the carina in resting and maximally stretched positions. Average tracheal length and number of the tracheal cartilages were compared in different body height groups in both sexes. We found that average body height was 160 +/- 6.4 cm and average tracheal length in resting position was 8.5 +/- 1 cm (range 6.5-11 cm) in females and average body height was 168.6 +/- 5.6 cm, average tracheal length was 8.7 +/- 1.1 cm (range 7-11.6 cm) in males, average number of tracheal cartilages was 13.6 +/- 1.7 (range 10-16) in females and 13.3 +/- 1.6 (range 10-19) in males and average number of the tracheal cartilages per centimeter was 1.6 +/- 0.2 in female and 1.5 +/- 0.2 in male cadavers in resting position. Average tracheal length in male group was found to be significantly different in cadavers with body height equal or taller than 170 cm in comparison to cadavers with body height shorter than 170 cm (p <0.05). This study revealed that the average tracheal length in Turkish people is shorter than the reported length in literature. It is worth commenting that there is a considerable difference between the different races with regard to tracheal length. Tracheal length may vary with body height.

    Is denervation surgery possible in the treatment of hallux rigidus? An anatomic study of cadaveric specimens
    (TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2021-01-01) Catal, Bilgehan; Keskinbora, Mert; Keskinoz, Elif Nedret; Tumentemur, Gamze; Azboy, Ibrahim; Demiralp, Bahtiyar
    Objective: The aim of this study was to provide anatomic considerations in the first metatarsophalangeal joint (FMPJ) innervation and to evaluate the feasibility of the denervation surgery in the treatment of hallux rigidus. Methods: In this cadaveric study, 14 fresh frozen cadaveric transtibial amputation specimens was used. For nerve dissection, dorsal and plantar longitudinal incision centered over the FMPJ were performed. Deep peroneal and dorsomedial cutaneous nerves were dissected in the dorsal aspect of the joint. Medial plantar nerve branches, medial and lateral hallucal nerves, were dissected in the plantar aspect of the joint. The presence, number, and location of articular branches to the FMPJ capsule were recorded. Dorsal and plantar incision length for proper dissection were also recorded. Results: Nerve dissection of the 14 specimens revealed the following number of articular branches from the relevant nerves: 14 from dorsomedial cutaneous nerves, 11 from deep peroneal nerves, 6 from medial hallucal nerve, and 5 from lateral hallucal nerve. Dorsal incision mean length was 60.53 (range, 42.48-85.12) mm, and the plantar incision mean length was 88.08 (range, 77.32-111.21) mm. Conclusion: Evidence from this study has shown that partial dorsal denervation of the FMPJ may be a technically feasible procedure along with the presence of superficially easily dissected nerves with relatively small incision.
