| nerve compression syndromes need to be considered for differential diagnosis of other painful conditions of the upper extremity. In some of the compression syndromes the assignment is already a clear history with characteristic Beschwerdesymtomatik and typical failure pattern to provide clinically safe. For other forms of complex electrophysiological measurements of peripheral nerves and an idea to the neurologist is essential. The definition of parent interference from changes in the cervical spine and intervertebral discs may require further X-ray diagnostics. Hormonal influences have to be considered as well as inflammatory processes, differential diagnosis and excluded. An accident history is to raise more. indication for surgical treatment: If the history and clinical symptoms clearly should not be delayed with the recommendation for surgical decompression of the nerve. The decision for surgery also depends on the clinical symptoms, the suffering of patients and has already demonstrated neurophysiological changes in measured values. If a conservative treatment with rail storage and, if local infiltration is carried out, should a clinical Control after 2-3 weeks in. If the symptoms do not improve, the surgical decompression is recommended in detail.
carpal tunnel syndromeThe median nerve runs on the wrist by an anatomical bottleneck, the carpal tunnel. The carpal tunnel is bounded by the flexor side carpal bones and flexor retinaculum by, a strong Bindegewebsband. If a compression syndrome of the nervous before at this level, the transverse carpal ligament divided surgically. This gives the median nerve to bend space and is easy to regenerate. From the median nerve, the sensory nerves arise for the thumb, index, middle, ring finger. The first is nerve branch of the wrist palmar branch off, an infringement of its branches leads to persistent complaints scars. The next departure is to thumb nerve motor branch of the motor. Its course is variable, an injury of this nerve leads to paralysis of the Thenarmuskels. Therefore, in all surgical procedures for decompression of the carpal tunnel syndrome, see the preservation of that Nevenstrukturen be paramount. |

| The course of the motor branch is not constant, but occurs with the variability shown here. The variability of the nerve paths is usually only a trained hand surgeon known. symptoms: Night pain in the thumb and Zeige-/Mittel-/Ringfinger, combined with numbness and "pins". shake out forced the hand of swelling and soreness in the hand. Often reinforced in the early morning hours, improvement in the day, increase by prolonged forced position (steering wheel in the car, newspaper, knitting) Ascending pain radiating to lower / upper arm and shoulder area possible but not obligatory. In the course of progressive damage to the nervous decrease in pain! This is not a sign of improvement when the numbness remains with loss of fine recognition of velvet and silk, or even a broadening of the 2-point discrimination performance. The further compression of the nerve leads to loss of motor fibers with loss of the thumb to make the little finger against (loss of the Opposition) and weakness of abduction (abduction). Fall of the Thenarmuskels. surgical procedures:
The most important part of the decompression of the median nerve is the complete division of the transverse carpal ligament. The classical open method, all main structures and a revision of the flexor tendon sheath is quite possible. The ramus palmaris is well presented and, if necessary, free of coarse fascial tissue as the motor motor branch. In the subcutaneous tissue between the skin and flexor retinaculum run small nerve branches of the cutaneous radial nerve, which cross the traditional incision at the level of the wrist. These so-called Taleisnik nerve transection occasionally lead to persistent discomfort with Narbenneuromen scar area. Endoscopic surgery The endoscopic procedure for decompression of the median nerve is created, a small incision at approximately the level of the wrist crease and a further cut in the palm of the hand at the distal end of the carpal tunnel (method by Chow). About these incisions are various special trocars and slot knife inserted and placed the video look, which is connected to an arthroscopy tower. Special knives are then used for division of the retinaculum under video visual control. The disadvantage is considered by many hand surgeons methodically induced lack evaluability criticized the median nerve itself and its above-described outlets. Likewise, an assessment of the flexor sheaths not be seeing an inflammatory thickening remains untreated it. A variant, the method is to Agee, which is by the use of other instruments, only one incision is required. The restrictions mentioned in the evaluability of the structures are similar for both techniques. incision for endoscopic decompression of the median nerve after Chow . Minimally invasive surgery is In this operation, it is the classic open surgery in which access is limited to the palm. Here, the proximal portion of the carpal tunnel is tunneled subcutaneously and raised with retractors. With the use of magnifying glasses, the transverse carpal ligament divided under direct vision. This results in the benefits of classic open approach, including specific audit capability of the carpal tunnel. The problems of scar discomfort are avoided, however, since the transverse Taleisnik-sensitive nerves may be spared. The motor and the motor branch is represented flexor tendon bearing can be inspected. An external neurolysis of the median nerve is also possible. By the obligatory use of an upper arm tourniquet is improved visibility in the wound and reduces the risk of damaging important structures. Here is the minimal invasive approach for decompression of the median nerve shown. The classical incision is limited to the palm. Remaining discomfort in the scar area are thus observed only in exceptional cases. anesthesia procedures: The division of the transverse carpal ligament is under local anesthesia, intravenous regional anesthesia or plexus block possible. As always the need for partial or extended tenosynovectomy must be considered, we use the axillary brachial plexus block preferred. Here is a stimulation device in the armpit of the nerve plexus of the arm visited targeted and stunned. The surgery is an outpatient procedure. For more details, contact the individual consultation of your doctor in the joint center of Wiesbaden. treatment: bandaging the hand and forearm with immobilization in a plaster cast or orthosis to the completion of wound healing and suture removal after 10 days. Intermediate wound checks vary according to schedule local findings. After healing, an increasing functional use of the hand is possible. By the nerve compression related pain are usually immediately after the decompression or after a few days improved significantly. Nerve deficits with reduced sensitivity or even paralysis of the Thenarmuskels require significantly longer recovery times. The recovery time depends on the duration and intensity of the pre-lined nerve damage. Lodge Guyon syndromeDistal ulnar nerve compression syndromeanatomy: The nerve enters nerve at the wrist, accompanied by the ulnar artery into a tunnel-shaped box the palm. This Madame Guyon Loge is more superficial than the carpal tunnel and continue to create upward. The bottom of the box is formed by the proximal transverse carpal ligament and flexor side to the box of fiber tracts of the retinaculum is limited, which combine with fiber tracts from the Bindegewebsplatte the palm (palmar fascia). In the course of the lodge, the ulnar nerve divides into its superficial and deep nerve branch. The surface is purely sensory and supplies the ring and little fingers. The deep nerve branch is purely motor and supplies the majority of the hand intrinsic muscles. A failure of the motor branch leads to paralysis and the so-called claw-hand. |

| symptoms This compression syndrome is much less common than carpal tunnel syndrome. A cluster with bikers is observed and is interpreted to repeated damage by pressure from the bicycle handlebars. That symptoms are highly variable, depending on whether a preferred motor or sensory or combined injury to the nerve is present. Typical sensations of the drawn-side ring finger and little finger can completely absent in purely motor impairment. Here then is the atrophy (Verschmächtigung) side, stretching the muscles between the thumb and second metacarpal bone groundbreaking. An electrophysiological study by the neurologist is obligatory. Because of the possibility of combined occurrence of carpal tunnel syndrome Guyon and a box should always be the measurement of both nerves. surgical procedures The angle-shaped incision is drawn somewhat more versatile than the traditional open surgery for carpal tunnel syndrome. From proximal to distal ulnar artery is the dissection lead structure. The nerve is exposed to his division into the superficial and deep portion and the free entry of the motor branch to the muscles of constrictions. Endoscopic surgical procedures are not possible. The incision for decompression of the Lodge is more Guyon create another and is of lesser extent than the incision for the classical open division of the carpal tunnel. anesthesia procedures The anesthetic options are similar to those of carpal tunnel release, see there. treatment elastic bandage on until the wound has healed and stringing 10th postoperative day. Functional exercise treatment, depending on the severity of preoperative nerve injury and motor deficits. Also wearing a brace Ulnarisspange than is necessary. Sulcus ulnaris syndromeThe nerve passes ulnar at the elbow joint in a groove called the sulcus nervi ulnaris, which is covered by a tight connective tissue. Following the withdrawal of the sulcus of the ulnar nerve runs between the two heads of the drawn-side Handgelenksbeugers (FCU), which he innervated by motor. After the distal ulnar nerve runs along the deep Langfingerbeugers (FDP) to the wrist. From the deep Langfingerbeugern be the proportion of the little finger and ring finger completely, together with the median nerve by the ulnar nerve innervated by motor. symptoms are typical of sensory disturbances Pinky and ring finger, often in combination with a strain pain during rapid flexion of the elbow joint. A palpable snap phenomenon in the sulcus can be caused by a hypermobile nerve in the sulcus with dynamic Luxationsneigung or by snapping triceps tendon. Here the subtle examination by the experienced hand surgeon is required for differentiation, because both require different surgical treatment symptoms. In the sulcus ulnaris compression syndrome can often be provoked an electrical sensation on tapping the nerve (positive Tinel's sign). If the injury by motor units of the nervous and atrophy of the hand intrinsic muscles and reduces the visible sweat, the Diagnosis to make easy. Differentiation of distal motor injury in Lodge Guyon is possible by a powerful contraction of the deep Langfingerbeugers for the small finger and points at a weakness of the ulnar nerve injury above the box Guyon (eg in sulcus) out. An electrostatic € graphical measurement is recommended in any case before any surgery at this level. surgical procedures For initial surgery and initial recurrences after previous division of the sulcus ulnaris we lead the advancement of the subcutaneous nerves with his nutritional accompanying vessel. For this, on the inside of the elbow joint, a cut length of about 8-10 cm is required. The only way to mobilize the nerve supply and the medial Muskelseptum be resected up to the arcade of Struthers. Any kind of edge formation through Faszienzüge or acute-angled bends of the nerves are to be strictly avoided. The formed subcutaneous pocket is secured with absorbable suture material. The course is completely full nerves tested intraoperatively in all operating positions of the elbow joint. anesthesia procedures We recommend the axillary plexus anesthesia and surgery can offer as an outpatient surgery. In circumstances, however, general anesthesia may be indicated. You can do this by the operators of the Joint center Wiesbaden be discussed individually. treatment removal of the drain on the following days with the first dressing change. Elastic bandage with angebeugtem elbow joint to the completion of wound healing and suture removal. Depending on the severity of preoperative nerve deficits and paralysis, postoperative physiotherapy and occupational therapy in combination with rail supply is required. The convalescence of the nerve may be several months. anterior interosseous nerve syndrome anatomy: runs after the passage of the elbow the ulnar nerve, median of easily coming between the two heads of the pronator teres and here is the strong interosseous nerve from anterior. This is mainly motor and innervates the long Daumenbeuger (FPL) for the long Langfingerbeuger index and middle fingers (FDP II / III) and the square Einwärtsdreher forearm. Sensible supplies of N. anterior interosseous the bow-side wrist and the wrist. The passage of the median nerve with its distribution in the level of the anterior interosseous Pronatorköpfe is subject to many anatomic variations and to recognize the constricting structures only during surgery. Numerous clinical function tests help the experienced hand surgeon to limit the lesion in more detail. When motor failure of the anterior interosseous here is the inability of the thumb and index finger to form a single circle trend. Symptoms The symptoms are similar to those of carpal tunnel syndrome, the night pain is less and no Tinel's sign is found at the carpal tunnel. The differentiation is done by a number of different muscles and functional tests, all aimed to provoke the constricted nerve at the site of narrowing. the Einwärtsdrehtest against the resistance of the examiner, the isometric flexion test of the elbow against resistance and the "Fingerhakel" test against resistance (FDPII / III): the most important. An obligate electrophysiological measurement demonstrates the Amount of injury. surgical procedures Because of the multiple anatomical variations must complete the course of the median nerve to be revised in the elbow and proximal forearm. Coming from the proximal brachial artery is used as a lead. Upon reaching the pronator teres must depending on the course of the nerves or muscles are spread incised. Since the departure of the anterior interosseous muscle is in the stomach and must be revised, should this operation be performed by a surgeon with microsurgical experience using optical magnification aids (magnifying glasses). The joint center of Wiesbaden all nerve compression syndromes are operating with magnifying glasses. anesthesia procedures We recommend the axillary plexus anesthesia and surgery can offer as an outpatient surgery. In circumstances, however, general anesthesia may be indicated. To do this can be by the operators of the joint center of Wiesbaden individual advice. treatment elastic bandage until the wound has healed and stringing. Action taken in relation to the preoperative motor deficits to be personalized. anatomy The radial nerve divides after its passage through the hiatus of the radial nerve in the lateral intermuscular septum in the elbow in the purely sensory Ranus superfizialis radial nerve and the predominantly motor branch of deep branch. The superficial branch runs with the radial artery distally and the deep branch passes through the supinator (Away Dreher of the forearm) and go to the extensor surface of the forearm where it innervates all the fingers and wrist extensor motor. The tendons at the entry level of the supinator (arcade Frohse) can lead to constriction. symptoms: errors usually sensory deficits. It is dominated by dull pain radiating the extensor-side forearm, similar to a Epicondylits radialis. For motor deficits, there is a corresponding weakness of the long finger extensor and / or the thumb. The entry into the Supinatorloge is often painful to pressure. The complaints are also that was felt when trying to external rotation against resistance and increases experienced in extension of the elbow joint. The middle finger extensor test is painful to the resistance. A certain degree of coincidence with the radial epicondylitis can complicate the diagnosis. We are therefore encouraged to be examined each patient with therapy-resistant tennis elbow in terms of a latent Supinatorlogen syndrome by a trained hand surgeon. An additional electrophysiological Measurement, which is often difficult to be carried out to support the indication for surgery. surgical procedures through a curved incision on the radial elbow radial is identified between the brachialis and the brachioradialis nerve. The muscular outlets are preserved and displayed the occurrence of the deep branch in the Supinatorloge, the present constricting tendon mirror and fiber tracts are severed and decompress the nerve. anesthesia procedures We recommend the axillary plexus anesthesia and surgery can offer as an outpatient surgery. In circumstances, however, a general anesthetic may be indicated. To do this can be by the operators of the joint center of Wiesbaden individual advice. treatment elastic bandage until the wound has healed and stringing. The further treatment is customized according to the preoperative motor deficits. anatomy the sensitive superficial radial nerve passes between the brachioradialis and extensor carpi radialis longus approximately 8 cm proximal to the wrist through the forearm. There you can find the nerve of bracelets, belts and jewelry chronic pressure damage. An irritation by rheumatic thickened paratenon is also possible. symptoms sense disturbances on the system side thumb and index finger area and the first Intermetacarpalraum. Minor electrical sensations and gain at Mißempfindungenmit provoked rotational movement of the wrist against resistance. surgical procedures cleavage of the forearm, revision of the nerve passage and, if resection of thickened paratenon. If necessary. Notch / Z-shaped extension of the tendon of the brachioradialis. anesthesia procedures surgery is an outpatient basis under local anesthesia or axillary brachial plexus block feasible. treatment dressing up for stringing, Narbenabhärtung, possibly silicon requirements for the prevention of keloids. |
