Description of the episeptal and interlaminar fascial tunnels for the superficial fibular nerve and its terminal branches.

KESİLMİŞ İNCİ | KURTOĞLU OLGUNUS ZELİHA

Purpose This study aimed to reveal the course of the superficial fibular nerve and its branches, whose entrapment may be responsible for anterior leg pain and is at risk in fasciotomies, according to the crural fascia laminae and the anterior inter muscular septum. Methods On the twenty cadaver legs, the location of the superficial fibular nerve and its branches, according to the crural fascia layers and anterior intermuscular septum, the course type in the tunnel, if any, and the superficialization pattern were defined. Results The number of cases in which the superficial fibular nerve and its branches traveled within a tunnel was found to be 15/20 (75%). The superficial fibular tunnel was defined as an “episeptal” and “interlaminar fascial” tunnel based on the nerve’s relationship with the fascia layers and anterior intermuscular septum. In 45% of the cases, the distance the nerve trav eled within the tunnel exceeded 3 cm. The finding that the superficial fibular tunnel exceeds 3 cm in 45% of cases suggests that, contrary to what is attributed in the literature, pain due to nerve compression cannot be explained solely by the pres ence and length of the tunnel. Other possible structural factors were whether the tunnel was episeptal or interlaminar fascial, whe...

Evaluation of the relationship of navicular tuberosity and tibialis posterior tendon with medial longitudinal arch.

BOBUŞ, ÖRS ALEV | KURTOĞLU OLGUNUS, ZELİHA

Background: Although it is suggested that the morphometry of the medial protrusion of tuberosity of navicular bone (TNm) and tibialis posterior (TP) tendons is related to this pathology, there is insufficient evidence. This study aimed to reveal the relations of the medial longitudinal arch (MLA) with the tendons of the TP and the TNm. Materials and methods: Dissections of this study were performed on the dorsal and plantar aspects of 34 formalin- fixed cadavers and amputated feet (15 female, 19 male). All attachment sites and connections of the main TP (TPmt) and slips are evaluated and classified. Morphometric measurements of TNm and all tendon slips were performed. Feet were assessed for pes planus (PP) presence using the navicular index and the first metatarsal- calcaneus angle and grouped as normal and pathological (pes planus). For all parameters, differences between groups, genders, and sides were evaluated. Results: The TP attached to the calcaneus, navicular, medial and lateral cuneiform, cuboid and fourth metatarsal bone (MT) in all feet. Additionally, slips were attached to the other tarsal and metatarsal bones (MT) with different combinations. The bony prominence exceeded the determined surgical reference line medially (6.73 ± 2.96 mm) in all feet. The width and len...

Anatomical Study of the Tibialis Posterior Tendon's Connections to the Plantar Muscles and Its Relationship With the Severity of Hallux Valgus

Kurtoğlu Olgunus Zeliha | Örs Alev Bobuş

Changes in tendon morphometry around first-row bones are linked to the hallux valgus (HV) development. However, there are very limited studies examining the relationship between the connection status of the tibialis posterior (TP) tendon to the adductor hallucis (ADH) and flexor hallucis brevis (FHB) tendons and the development of HV. This study aimed to investigate the association between these tendon connections and the occurrence of HV. The study included 24 formalin-fixed adult cadavers and amputee feet (10 female, 14 male). The attachment sites and connections between the ADH, FHB, and TP tendons were recorded. Feet were classified into three groups: no connection between the three tendons (Group I), connection between TP and FHB (Group II), and connection between TP, FHB, and ADH (Group III). HV angle values and subgroups (normal, mild, and moderate-severe) were defined to assess the degree of HV. Feet were grouped based on tendon attachment status, and the distribution of HV subgroups was statistically analyzed. HV angles in Group III were significantly larger than in Groups I and II (= 0.000, p = 0.024). While tendon connection was detected in only 20% (1/5) of feet without HV, tendon connection was detected in 64% (7/11) of mild HV and in all feet with moderate-severe HV...

The effect of hallux valgus on the anatomy of the nerves around the first metatarsal bone

Kurtoğlu Olgunus, Zeliha

Objective To identify the variations in the location of the nerves that may be at risk in hallux valgus (HV) surgery, and to reveal whether these nerves are affected by the anatomical changes associated with HV. Method In the formalin fixed, 46 lower extremities (19 female, 27 male) (9 normal, 14 mild HV, 21 moderate/severe HV), extensor hallucis longus tendon (EHL), deep plantar artery, medial dorsal cutaneous (MDCN), deep fibular (DFN), common plantar digital (CPDN) and proper plantar digital (PPDN) nerves were examined. The branches of MDCN extending to the medial side of foot were recorded in three segments. The positional topography of nerves according to EHL were analyzed on 360° circle and clock models. Results Sex-related differences observed in some parameters in direct measurements were not found in the clock model comparisons. In advanced HV angles (> 20°), DFN was closer to EHL in the distal part of the metatarsal bone, while there was no difference in the proximal. The intersection of the medial branch of the MDCN with the EHL was more proximal in HV cases than in normal feet. The location of the nerves in the clock pattern did not change in HV. Of the nerve branches reaching the medial side of the foot, 65.2% were in Part I, 71.7% in Part II, and 4.3% in Part III....
