The superficial peroneal nerve (SPN) provides fundamental motor and sensory innervation to the leg and foot. A variety of surgical procedures is performed in the vicinity of this nerve, requiring that the surgeon be familiar with its specific anatomy. We dissected 111 legs to define the anatomic position of the SPN and found that the nerve had 4 distinct variations in location. In 77 (69.4%) specimens, the nerve coursed within the lateral compartment of the leg, while in 18 (16.2%) of the legs, the nerve split and contained branches in both the lateral and anterior compartments. The nerve in 7 (6.3%) legs was found within the intermuscular septum, and in 9 (8.1%) of the specimens, the SPN traveled only within the anterior compartment. These results confirm 4 anatomic variants of the SPN, which will aid surgeons in locating the nerve in the lateral aspect of the leg. 相似文献

The superficial peroneal nerve presents great anatomic variability regarding its emergence from the crural fascia, course, branching pattern, and distribution area. Entrapment neuropathy of the superficial peroneal nerve has been documented in the published data, resulting in pain and paresthesia over the dorsum of the foot. We report a case of a female cadaver in which an accessory superficial peroneal sensory nerve was encountered. The nerve originated from the main superficial peroneal nerve trunk, proximal to the superficial peroneal nerve emergence from the crural fascia, and followed a subfascial course. After fascial penetration, the supernumerary nerve was distributed to the skin of the proximal dorsum of the foot and lateral malleolar area. A potential entrapment site of the nerve was observed at the lateral malleolar area, because the accessory nerve traveled through a fascial tunnel while perforating the crural fascia, and presented with distinct post-stenotic enlargement at its exit point. The likely presence of such a very rare variant and its potential entrapment is essential for the physician and surgeon to establish a correct diagnosis and avoid complications during procedures to the foot and ankle region. 相似文献

Fasciotomy for chronic exertional compartment syndrome can be achieved by a variety of methods, many of which involve the
blind passage of scissors or a fasciotome to release the affected compartments. We describe a modified open technique of fasciotomy
which provides direct visualization of the fascia and the superficial peroneal nerve, using a single small incision. This
technique requires a 4-cm longitudinal incision centered at the midpoint of the fibula. Subcutaneous tissues are dissected
and a fascial incision is made. Langenbach retractors are used to lift the skin from either end of the wound. A light is used
to transilluminate the skin proximal and then distal to the wound, and a fasciotome is used to extend the fasciotomies for
both anterior and lateral compartments. Fasciotomy using this method was carried out on 20 cadaveric legs from 10 specimens.
After decompression, a fulllength skin incision was made and the subcutaneous tissues were dissected to assess adequacy of
release, anatomic course of the superficial peroneal nerve and complications. Fasciotomy was completed in twenty legs for
both the anterior and lateral compartments. A complete fascial release was attained for both compartments in all legs. There
were no retained fascial bands or nerve injuries. Fasciotomy using this method may be a safe and reliable method for compartment
decompression, and may reduce iatrogenic risk to neurovascular and muscular structures in clinical practice. 相似文献

A paucity of appreciation exists that the “double crush” phenomenon can account for persistent leg symptoms even after spinal neural decompression surgery. We present an unusual case of multiple locations of nerve compression causing persistent lower limb paresthesia in a 40-year old male patient. The patient's lower limb paresthesia was persistent after an initial spinal surgery to treat spinal lateral recess stenosis thought to be responsible for the symptoms. It was later discovered that he had peroneal muscle herniations that had caused superficial peroneal nerve entrapments at 2 separate locations. The patient obtained much symptomatic relief after decompression of the peripheral nerve. The “double crush” phenomenon and multiple levels of nerve compression should be considered when evaluating lower limb neurogenic symptoms, especially after spinal nerve root surgery. 相似文献

Eighty-five legs in forty-four cadavera were dissected to determine the course of the superficial peroneal nerve from its origin to its termination as dorsal cutaneous nerves of the foot. Particular attention was paid to the relationship of the nerve with the intermuscular septum between the anterior and lateral compartments of the leg. In sixty-two (73 per cent) of the legs, the nerve coursed within the lateral muscle compartment from its origin to its exit through the crural fascia. In twelve (14 per cent) of the legs, the nerve had a variable course in the lateral compartment, crossed into the anterior compartment, and passed through the fascia. In ten (12 per cent) of the legs, the nerve divided in two, with branches in both the anterior and the lateral compartment. In one leg, the nerve never lay deep to the peroneus longus but ran along the deep surface of the fascia before exiting distally. The nerve or its branches passed through the fascia three to eighteen centimeters proximal to the lateral malleolus. 相似文献

The anterior approach to the ankle for surgery can result in injury to the superficial peroneal nerve, resulting in a painful neuroma and significant patient morbidity. A paucity of data is available evaluating the role of the superficial peroneal nerve to deep peroneal nerve transfer as a method of treatment of neuromas in continuity after ankle arthrodesis. We describe 11 patients who underwent nerve transfer with nerve allograft and conduit repair to treat recalcitrant painful neuromas after ankle arthrodesis. At a mean follow-up period of 31 months, the mean visual analog pain scale score had improved from 7.9 preoperatively to 2.45 postoperatively (p?<?.0001). These data suggest that nerve transfer with a nerve allograft can provide significant clinical improvement for painful neuromas of the peripheral nerves at the ankle. 相似文献

OBJECTIVES: Endoscopic ligation of perforating veins is useful in treatment of perforating vein incompetence. Over the last few years the topic of interest has been the medial side of the lower leg; however, laterally located venous ulcers (10% of all) are of equal importance. Our poor results with lateral subfascial endoscopic perforating vein surgery (SEPS) procedures led us to study the anatomy of the perforating veins in the lateral leg. The presence of persistent insufficient perforating veins in our patients suggests that our procedure failed because of misinterpreted perforator anatomy. METHODS AND RESULTS: Anatomic dissection was performed in 16 cadavers in two stages, subcutaneously and subfascially. Perforating veins were classified relative to the short saphenous vein and intermuscular septa, with coordinates. Three hundred fifty-one perforating veins were found, for an average of 21.9 perforating veins per leg. The results showed that there is alignment of the perforating veins according to the septa between the anterior and peroneal compartment and between the peroneal compartment and the superficial dorsal compartment. Most of the perforating veins did not correlate with the short saphenous vein. CONCLUSION: Poor clinical results of lateral SEPS procedures might be improved after adjustment of the procedure for new anatomic information, which shows alignment of perforating veins along the intermuscular septa, obligating full septa dissection on the lateral side. 相似文献

Abstract 10 embalmed cadaver forearms and wrists were dissected to determine the anatomical course of the superficial branch of the
radial nerve in the distal forearm. The superficial radial nerve bifurcated in two branches at a mean of 54,7 mm proximal
to the radial styloid. From the styloid process of the radius, the mean distance to the closest dorsal branch of the superficial
radial nerve was 3,5 mm and the mean distance to the closest volar branch was 9,8 mm. The mean distance between the closest
branch of the superficial radial nerve and Lister?s tubercle was 16,4 mm. The crossing point between the nerve and the cephalic
vein was located at a mean of 54,3 mm proximal to the styloid process. At the level of styloid process the mean distance between
the closest dorsal branch of the superficial radial nerve and the first dorsal compartment was 15,2 mm and between the closest
volar branch and the first dorsal compartment 4,4 mm. Detailed knowledge of anatomic characteristics of the superficial branch
of the radial nerve may help prevent injury during operations and treat traumatic lesions of the nerve. Because of great variations
in the course of the superficial radial nerve we could not define an absolute safe zone for surgical procedures on the distal
forearm. Iatrogenic lesions of the superficial radial nerve are described complications of percutaneous procedures. Therefore
open surgical approaches are recommended.

STUDY DESIGN: Experimental evaluation of intracompartmental pressures in a fresh above knee amputated human leg. OBJECTIVES: To determine what effect raised pressure in one compartment of the lower leg had upon its neighbour. SUMMARY OF BACKGROUND DATA: There has been no previous reports of isolated compartment pathology, following low velocity trauma, causing a compartment syndrome in all four compartments of the lower leg. METHODS: Immediately after leg amputation, the intracompartmental pressure in the deep posterior compartment was artificially raised to 100 mmHg with infused 0.9% sodium chloride solution. The resultant pressure changes in remaining compartments were recorded over 30 min. RESULTS: Five legs were evaluated. After 30 min, the mean maximum intracompartmental pressure increase found in the superficial posterior, anterior and peroneal compartments was 78.4 mmHg (range 65-94 mmHg), 25.2 mmHg (range 14-31 mmHg) and 24.8 mmHg (range 15-31 mmHg), respectively. CONCLUSIONS: This experimental data and case reports show that a compartment in which there is raised pressure may exert external pressure on a neighbouring compartment that can result in physiological changes to induce a compartment syndrome within that neighbour. The importance of assessing all compartments within a limb segment, even when associated with low velocity trauma, remains paramount. 相似文献

PURPOSE: To investigate the anatomic relationships of the posterior antebrachial cutaneous nerve (PABCN) to anatomic landmarks on the lateral side of the elbow. METHODS: The PABCN was explored in 30 cadaveric upper extremities. Distances were noted from easily identifiable structures including the lateral epicondyle, the lateral intermuscular septum, and the radial nerve. RESULTS: The path of the PABCN follows the spiral groove initially, diverging as the radial nerve pierces the lateral intermuscular septum. The PABCN emerges from the posterior compartment through a hiatus in the deep fascia at a mean of 6.6 cm proximal to the lateral epicondyle and passes a mean of 2.1 cm anterior to the lateral epicondyle. CONCLUSIONS: The anatomic relationships determined in this study should enable the surgeon to avoid injuring the PABCN when performing surgery in the lateral elbow region. 相似文献

The objective of this study was to examine the effect of position of the knee and ankle on intracompartmental pressures in the leg. Slit catheters were introduced bilaterally into all four muscle compartments of the lower extremities of six healthy volunteers. Intracompartmental pressures were monitored with the catheters while the ankle joint was passively held in full dorsiflexion, full plantar flexion, or neutral with the knee flexed 90 or 10 degrees or fully extended. Statistical analysis revealed that intracompartmental pressure increased significantly in all four compartments when the ankle was passively dorsiflexed. Pressure in the superficial posterior and lateral compartments was dependent on knee position and in the deep posterior and anterior compartments it was independent of knee position. In addition, pressure in the deep posterior compartment decreased significantly when the ankle was placed in full plantar flexion, and that finding was independent of knee position. Anterior compartment pressure was not significantly elevated by full passive plantar flexion of the ankle. 相似文献

PURPOSE: To explore the course of the radial nerve in the brachium and to identify practical anatomic landmarks that can be used to avoid iatrogenic injury during humerus fracture fixation. METHODS: Data were collected from 27 adult cadaveric specimens, including 18 embalmed cadavers and 9 fresh-frozen limbs. Measurements were taken using osseous landmarks to define the relationship of the radial nerve and the posterior and lateral humerus. The extremities were studied further to determine the association of the radial nerve and anatomic landmarks on both longitudinal and cross-sectioned specimens. RESULTS: A 6.3 cm +/- 1.7 segment of radial nerve was found to be in direct contact with the posterior humerus from 17.1 cm +/- 1.6 to 10.9 cm +/- 1.5 proximal to the central aspect of the lateral epicondyle, centered within 0.1 cm +/- 0.2 of the level of the most distal aspect of the deltoid tuberosity. The radial nerve lay in direct contact with the periosteum in all specimens, without evidence of a structural groove in the humerus in any specimen. On entering the anterior compartment, the radial nerve had very little mobility as it was interposed between the obliquely oriented lateral intermuscular septum and the lateral aspect of the humerus. As it extended distally, the nerve coursed anterior to the humerus and became protected by brachialis muscle at the level of the proximal aspect of the lateral metaphyseal flare. CONCLUSIONS: The radial nerve is at risk of injury with fractures of the humerus and with subsequent operative fixation in 2 areas. The first is along the posterior midshaft region for a distance of 6.3 cm +/- 1.7 centered at the distal aspect of the deltoid tuberosity. The second is along the lateral aspect of the humerus in its distal third from 10.9 cm +/- 1.5 proximal to the lateral epicondyle to the level of the proximal aspect of the metaphyseal flare. The deltoid tuberosity is a consistent and practical anatomic landmark that can be used to determine the level of the radial nerve along the posterior aspect of the humerus during operative fixation from an anterior approach. 相似文献

Compartment syndrome of the lower leg or foot, a severe complication with a low incidence, is mostly caused by high-energy
deceleration trauma. The diagnosis is based on clinical examination and intracompartmental pressure measurement. The most
sensitive clinical symptom of compartment syndrome is severe pain. Clinical findings must be documented carefully. A fasciotomy
should be performed when the difference between compartment pressure and diastolic blood pressure is less than 30 mm Hg or
when clinical symptoms are obvious. Once the diagnosis is made, immediate fasciotomy of all compartments is required. Fasciotomy
of the lower leg can be performed either by one lateral incision or by medial and lateral incisions. The compartment syndrome
of the foot requires thorough examination of all compartments with special focus on the calcaneal compartment. Depending on
the injury, clinical examination, and compartment pressure, fasciotomy is recommended via a dorsal and/or medial plantar approach.
Surgical management does not eliminate the risk of developing nerve and muscle dysfunction. When left untreated, poor outcomes
with contractures, toe deformities, paralysis, and sensory neuropathy can be expected. In severe cases, amputation may be
necessary. 相似文献

BackgroundThere is a considerable overlap of symptoms between chronic exertional compartment syndrome (CECS) of the anterior and lateral compartments of the lower leg and entrapment neuropathy of the superficial peroneal nerve (SPN). We describe a minimally invasive, single incision surgical technique for release of both the compartments and the SPN in the same setting. The operative technique involves a minimal anterolateral approach at the level where the SPN pierces the subcutaneous fascia.MethodsNineteen patients were operated with the method and 24 anterolateral compartments (5 cases with bilateral CECS) were released. Anterior and lateral, proximal and distal fasciotomies were performed sequentially with the use of a specific instrument designed for carpal tunnel release (KnifeLight®, Stryker). This is a modification of a fasciotome with an intergrated light source which allows for transillumination of the subcutaneous tissues. The SPN and its main branches with their anatomical variations were explored and decompressed at the same setting.ResultsPatients who met the inclusion criteria were reviewed at one year postoperatively with a Numeric Analog Pain Scale (NAS) and the Linkert satisfaction scale. There were 5 men and 10 women, aged 35.7 (21–60) years. The NAS scores improved by a mean 6 points (p < 0.0001) postoperatively and 86.6% (13/15) of the patients were either satisfied or very satisfied with the operation. There were no intraoperative complications. There were two patients with SPN neuropathy symptoms postoperatively, one of whom required revision surgery. One patient had recurrence of less intense symptoms in the first postoperative year with no need for reoperation.ConclusionsThe simultaneous release of the anterolateral compartment of the leg and decompression of the SPN with the described technique was safe and effective. It combined the advantages of a single, minimally invasive approach with the subcutaneous transillumination, and had a high patient satisfaction and a low recurrence rate.Level of evidenceRetrospective case series, Level IV. 相似文献
