Summary We studied the anatomy of the anterolateral and anterocentral portal sites for ankle arthroscopy with reference to the superficial peroneal nerve (SPN) in 29 cadavers (51 ankles) and the deep peroneal nerve (DPN) in 11 cadavers (21 ankles). In relation to the level of division into the medial and intermediate cutaneous nerves and their terminal branches, we classified the structure of the SPN surrounding the ankle into five types. We also identified the point where the SPN and the DPN cross the level of the talocrural joint. 32% of specimens had different SPN division types on the two sides and there was an average of 2 nerves at the level of the talocrural joint. Branches of the SPN were found lateral to the edge of the peroneus tertius tendon in 11.8% of specimens, and at its lateral edge in 27.5%. The DPN and some branches of the SPN were positioned around the lateral edge of the extensor hallucis longus tendon. We consider that the anterolateral portal should be made at least 2 mm lateral to the peroneus tertius tendon to avoid injury to the SPN, since the diameter of the scope is 2.7 mm. The anterocentral portal is unsuitable for arthroscopy due to a high risk of injury to the DPN and branches of the SPN.
Etude anatomique des nerfs fibulaires superficiel et profond au niveau des voies antéro-latérale et antéro-centrale pour arthroscopie de la cheville
Résumé Nous avons étudié l'anatomie des voies antéro-latérale et antéro-centrale pour arthroscopie de la cheville, et notamment leur rapport avec le n. fibulaire superficiel (NFS) sur 29 cadavres (51 chevilles) et le n. fibulaire profond (NFP) sur 11 cadavres (21 chevilles). Par rapport au niveau de division des nn. cutanés médial et intermédiaire et de leurs branches terminales, nous avons classé la disposition du NFS en regard de la cheville dans 5 types. Nous avons identifié le point où le NFS et le NFP croisaient l'interligne articulaire talo-jambier. 32% des spécimens présentaient un site de division du NFS différent à droite et à gauche, et il y avait en moyenne deux nerfs en regard de l'art. talo-jambière. Les branches du NFS étaient latérales au bord du tendon du m. troisième fibulaire dans 11,8 % des cas, en regard de son bord latéral dans 27,5% des cas. Le NFP et quelques branches du NFS se trouvaient en regard du bord latéral du tendon du m. long extenseur de l'hallux. Nous pensons que la voie antéro-latérale devrait être réalisée au moins 2 mm latéralement au tendon du m. troisième fibulaire pour éviter la blessure du NFS, car le diamètre de l'endoscope est de 2,7 mm. La voie antéro-centrale est, pour nous, inappropriée pour l'arthroscopie de la cheville en raison d'un risque élevé de la blessure du NFP et des branches du NFS.相似文献

We aimed to navigate the surgeon regarding the localization of the main anatomical structures at the anterior part of the ankle joint, in order to find easily the safest anatomical points with reference to the superficial peroneal nerve (SPN), in particular for anterolateral portal placement in ankle arthroscopy. Sixty-three ankles in 36 fresh cadavers were dissected. In all specimens we examined (1) the distance between the SPN bifurcation and the most distal point of the lateral malleolus; and at the level of ankle joint, (2) the number of SPN, (3) the distance between the medial and intermediate dorsal cutaneous nerves, which are branches of the SPN, (4) the localization of the peroneus tertius (PT) tendon in relation to the lateral malleolus, (5) the width of the extensor digitorum longus (EDL) tendon, (6) the relationship of the PT tendon and (7) the relationship of the extensor hallucis longus (EHL) tendon with the SPN. The results were as follows: (1) In 41 ankles with bifurcation (65%) the average distance was 71.8±35.3 mm. (2) There were two SPN branches in 39 (62%), three branches in seven (11%) and one branch in 17 (27%) cases. (3) In 39 ankles with two branches of the SPN, the mean distance was 15.2±7.1 mm. (4) The lateral border of the PT tendon was positioned a mean distance of 20.8±3.3 mm proximal and 25.2±5.8 mm medial to the reference points. (5) The mean width was 10.1±2.9 mm. (6) In 42 ankles (67%) the distance between the lateral border of the PT tendon and the SPN was a mean of 6.2±6.6 mm, median of 3 mm (range 0–22 mm lateral to the tendon). (7) In 56 cases (89%) a branch of the SPN was found a mean of 6.6±4 mm and a median of 6 mm lateral to the EHL tendon, and in seven cases (11%) on the tendon. According to our study, in ankle arthroscopy the risk of the SPN injury is maximal in the 0–3 mm lateral to the PT tendon. To avoid injury to the SPN, the safest placement of the anterolateral portal is 4 mm lateral to the PT tendon. 相似文献

The main goal of the present study was to estimate the ankle joint angle from the peroneal and tibial electroneurography (ENG)
recordings. Two single-channel cuff electrodes for recording ENG were placed on the proximal part of rabbit peroneal and tibial
nerves respectively and static positioning and ramp-and-hold stretches were performed to characterize the static and dynamic
ENG responses. An ENG model, consisting of static and dynamic parts, was constructed to relate ENG to ankle angle trajectory
and an inverse ENG model was derived to predict ankle angle. The results showed that the new model could accurately estimate
large-range ankle angles during and after ramp-and-hold movements. Our study provides a basis for implementing joint angle
tracing without using artificial angle sensors. 相似文献

The rich sensory innervation of the ankle and foot is manifest through the numerous communicating branches linking the neural trunks, particularly the superficial peroneal and sural nerves on the anterolateral aspect of the hindfoot. The 35 communicating branches seen in 55 dissections (58%) were proximal in half of the cases, lying in the malleolar and lateral tarsal regions, and distal in the other half, in the metatarsal region. The communicating branch was straight in 25 cases and curved in 11. The average distances of the communicating branch from the crest of the lateral malleolus and the tubercle of the 5th metatarsal was 4.7 and 4.1 cm, but there was a wide range of values. We believe that stretching of the proximal communicating branch during forced inversion of the ankle and/or foot or during fractures of the calcaneus or direct injury in surgical approaches or arthroscopy of the ankle may lead to unexplained pre- and submalleolar pain. Advances in modern imaging may allow recognition of these branches and guidance of infiltration and even neurolysis in cases of failure of conservative treatment. 相似文献

The possibility of deep peroneal nerve neurotisation by the superficial peroneal nerve: an anatomical approach 总被引:2,自引:0,他引:2

Neurotisation involves transfer of nerves for the restoration of function following injury. A number of nerves have been used in different part of the peripheral nervous system. This study was undertaken to develop a practical and relatively safe surgical approach to the treatment of L4 root lesion's. We examined the effectiveness and safety of neurotisation of the deep peroneal nerve and its branches by the superficial peroneal nerve. Twelve legs of dissected cadavers provided for teaching purposes in the anatomy laboratory were used to display the common peroneal nerve and its branches. Each branch was measured using calipers and analysed to investigate the possibility of neurotisation of the deep peroneal nerve by the superficial peroneal nerve and its branches. It was found that of the measured branches, transposition was possible between those to peroneus longus and tibialis anterior on the basis of their diameter and length. In recent decades, advances in microsurgical reconstruction and understanding of the microanatomy have played major roles in improving the results of surgical treatment of nerve injuries. There is a need for further experimental studies on the feasibility of this surgical approach. 相似文献

This study examined the anatomic location of the motor entry point (MEP) and branching point at the proximal and distal points of the tendon of the peroneal muscle by visual observation. Forty-three fresh legs of 25 adult bodies which had been donated to science were investigated in this study. The mean length of the reference line between the most proximal point of the head of the fibula (PHF) and the most distal point of the malleolus of the fibula (DMF) was 33.4 ± 2.5 cm. The MEPs of the peroneus longus (PL) and peroneus brevis (PB) gathered from 20 to 40% (7.0-13.0 cm) and 40 to 60%, respectively. The branching point where the nerve was divided to innervate the PL and PB was 10% and 28% from the PHF, respectively. These anatomic results suggest appropriate areas where to inject phenol or other agents for a MEP block in the case of a spastic lower extremity as well as guidelines for an electromyography conduction test. 相似文献

Regional anesthesia relies on a sound understanding of anatomy and the utility of ultrasound in identifying relevant structures. We assessed the ability to identify the point at which the superficial peroneal nerve (SPN) emerges through the deep fascia by ultrasound on 26 volunteers (mean age 27.85 years ± 13.186; equal male: female). This point was identified, characterized in relation to surrounding bony landmarks (lateral malleolus and head of the fibula), and compared to data from 16 formalin‐fixed human cadavers (mean age 82.88 years ± 6.964; equal male: female). The SPN was identified bilaterally in all subjects. On ultrasound it was found to pierce the deep fascia of the leg at a point 0.31 (±0.066) of the way along a straight line from the lateral malleolus to the head of the fibula (LM‐HF line). This occurred on or anterior to the line in all cases. Dissection of cadavers found this point to be 0.30 (±0.062) along the LM‐HF line, with no statistically significant difference between the two groups (U = 764.000; exact two‐tailed P = 0.534). It was always on or anterior to the LM‐HF line, anterior by 0.74 cm (±0.624) on ultrasound and by 1.51 cm (±0.509) during dissection. This point was significantly further anterior to the LM‐HF line in cadavers (U = 257.700, exact two‐tailed P < 0.001). Dissection revealed the nerve to divide prior to emergence in 46.88% (n = 15) limbs, which was not identified on ultrasound (although not specifically assessed). Such information can guide clinicians when patient factors (e.g., obesity and peripheral edema) make ultrasound‐guided nerve localization more technically challenging. Clin.

This report presents a case of neural fibrolipoma arising from the superficial peroneal nerve in the ankle. A 28-year-old woman was referred with a soft tissue mass in the anterior aspect of the right ankle, which had been gradually enlarging for the past 10 years. Magnetic resonance imaging showed a mass lesion, measuring approximately 8 x 3 x 2 cm, with high to partially low signal intensity on both T1- and T2-weighted images. A band of low signal intensity within the lesion, which is indicative of coexistence with the tumor and the superficial peroneal nerve, could be detected on both T1- and T2-weighted images. The patient underwent an excisional biopsy. The specimen microscopically consisted of nerve bundles and fibro-fatty proliferation with abundant collagen fibers. Immunoreactivity for CD34 antigen antibody was detected in fibrous spindle cells. This is the first report to present an immunohistochemical profile of neural fibrolipoma. Neural fibrolipoma should be considered as a differential diagnosis when a lipomatous lesion is encountered in the foot or ankle as well as in the upper extremities. 相似文献

BACKGROUND: Radiography is commonly used for investigating ankle injury, but is inadequate for diagnosing some ankle fractures and ligamentous injuries. Thus, radiography cannot be used for accurate fracture classification or to formulate a treatment program. In contrast, magnetic resonance imaging can clearly show occult ankle fractures and ligamentous injuries, and can diagnose fracture combined with ligamentous injury. Therefore, radiography combined with magnetic resonance imaging may potentially be adequate for fracture classification and postoperative evaluation. 相似文献

Dimensions of the anterior tarsal tunnel and features of the deep peroneal nerve in relation to clinical application 总被引:1,自引:0,他引:1
Background The aim of this study was to demonstrate anatomical features of the anterior tarsal tunnel and the deep peroneal nerve and
to discuss the importance of these structures for the anterior tarsal tunnel syndrome and some other surgical approaches to
minimize the injury risk.
Methods Lower limbs of 18 formalin fixed cadavers were examined. The limbs showed no evidence of pathology or trauma.
Results The lateral length of the tunnel was 21.7 ± 4.3 mm and the medial length of the tunnel was 55.0 ± 9.0 mm. The width of the
tunnel at the inferior border between the extensor hallucis longus and extensor digitorum longus tendons was 12.6 ± 2.1 mm.
The location of the deep peroneal nerve bifurcation was in the anterior tarsal tunnel in 31 specimens (86.1%) and distal to
the tunnel in two specimens (5.6%). In three specimens (8.3%) there was no bifurcation because of the absence of the medial
terminal branch of the deep peroneal nerve. In these three specimens, the superficial peroneal nerve distributed to the adjacent
sides of the great and second toes. Bifurcation above the tunnel was not observed in our specimens. There was connection between
the deep peroneal nerve and the superficial peroneal nerve in 10 specimens (27.8%) in the first interdigital space. During
the observations, the presence of a fibrous band over the nerve and vessel was noted in 22 specimens (61.1%).
Conclusions We believe that a detailed anatomic knowledge of the anterior tarsal tunnel and the deep peroneal nerve will be of help during
surgical approaches to this area and the diagnosis of the problems related to the peripheral nerves on the dorsum of the foot.
This study was presented on the 4th Asian-Pacific International Congress of Anatomists (APICA 2005) in Kusadasi, Turkey on
