Endoscopic Ganglionectomy of the Tarsal Tunnel: A Medial Approach.

ABSTRACT: A ganglion inside the tarsal tunnel can compress the tibial nerve, leading to posterior tarsal tunnel syndrome. Classically, the ganglion is resected with an open approach. This requires release of the flexor retinaculum and dissection around the tibial neurovascular bundle, which may induce fibrosis around the tibial nerve. Endoscopic resection of a tarsal tunnel ganglion via a posterior approach has been reported. The purpose of this Technical Note is to describe the medial approach of endoscopic ganglionectomy of the tarsal tunnel. This is indicated for tarsal tunnel ganglia compressing the tibial nerve and extending to the flexor retinaculum. It is contraindicated if there is other pathology of the tarsal tunnel that demands open surgery; the ganglion compresses the tibial nerve from its deep side and does not extend to the flexor retinaculum; or in the presence of intraneural ganglion of the tibial nerve.

Endoscopic Resection of the Tarsal Tunnel Ganglion.

Project description:The tarsal tunnel ganglion is a cause of posterior tarsal tunnel syndrome. Open resection of the ganglion calls for release of the flexor retinaculum and dissection around the tibial neurovascular bundle. This can induce fibrosis around the tibial nerve. We report the technique of endoscopic resection of the tarsal tunnel ganglion. It is indicated for tarsal tunnel ganglia arising from the adjacent joints or tendon sheaths and compressing the tibial nerve from its deep side. It is contraindicated if there is other pathology of the tarsal tunnel that demands open surgery; if the ganglion compresses the tibial nerve from its superficial side, which calls for a different endoscopic approach using the ganglion portal; or if an intraneural ganglion of the tibial nerve is present. The purpose of this technical note is to describe a minimally invasive approach for endoscopic resection of the tarsal tunnel ganglion.

Endoscopic Ganglionectomy of the Extensor Digitorum Longus Tendon: An Extraganglionic Approach.

Project description:AbstractGanglion is the most common soft tissue mass in the foot and can be painful and affect comfort wearing shoes. The usual treatment of a ganglion is conservative: careful neglect, manual rupture, or aspiration. When the lesion is recurrent or painful, surgical excision is recommended. The purpose of this Technical Note is to describe the extraganglionic approach of endoscopic ganglionectomy of the extensor digitorum longus tendon. This surgery has the advantage of being minimally invasive and having better cosmetic result, with less surgical trauma to the soft tissue.Level of evidenceLevel 1: foot and ankle; Level 2: other (ganglion).

Endoscopic Ganglionectomy of the Elbow.

Project description:Resection of the ganglion of the elbow is indicated if the size or location of the cyst impairs function or causes significant pain. Arthroscopic decompression or endoscopic resection of the cyst is the minimally invasive surgical option. It has the potential advantage of better cosmetic results and less soft-tissue dissection. Endoscopic resection is indicated if the cyst is not communicating with the joint or the communication is not identifiable arthroscopically or if there is a long and narrow communication placing the cyst away from the elbow joint. Preoperative magnetic resonance imaging is essential for surgical planning.

Endoscopic Ganglionectomy of the Volar Radial Wrist Ganglion.

Project description:Volar ganglion cyst of the wrist is a common hand problem faced by orthopaedic surgeons. Excision is indicated if it is painful. Arthroscopic ganglionectomy of the wrist ganglion has been reported with the advantage of minimally invasive surgery. Most of them involve elimination of the valvular mechanism and internal drainage of the ganglion fluid to the wrist joint. The access of the ganglion sac is limited especially for a multiloculated cyst. The purpose of this Technical Note is to report the technique of endoscopic resection of the volar radial wrist ganglion. This can ensure complete resection of the ganglion sac especially for the multiloculated one.

Endoscopic Ganglionectomy and Release of the Sixth Extensor Compartment.

Project description:Stenosing tenosynovitis of the extensor carpi ulnaris is one of the causes of dorsoulnar wrist pain. Conservative treatment is usually effective to alleviate the pain. Surgical release of the retinaculum of the sixth extensor compartment is indicated if conservative treatment cannot alleviate the pain. The purpose of this Technical Note is to describe the technical details of endoscopic release of the sixth extensor compartment via a 2-portal approach. Endoscopic resection of a ganglion over the sixth compartment can also be performed via the same approach.

Endoscopic Ganglionectomy of Palmar Ganglion via Flexor Carpi Radialis Tendoscopy.

Project description:Palmar ganglion is rare. Deep palmar ganglion usually arises from the wrist joint and may cause compression neuropathy. Superficial palmar ganglion may arise from the flexor tendons of the wrist. The chance of compression neuropathy is expected to be less than deep palmar ganglion. However, there is a higher chance of perforation through the skin and the ganglion may affect hand grip. Open resection of the ganglion does not require extensive deep soft tissue dissection. However, the skin incision can still be extensile to trace the stalk to the tendon of origin. The purpose of this Technical Note is to report the details of endoscopic ganglionectomy for superficial palmar ganglion arising from the flexor carpi radialis tendon.

Effect of Lateral Sliding Calcaneus Osteotomy on Tarsal Tunnel Pressure.

Project description:BackgroundLateral sliding calcaneus osteotomies are common procedures to correct hindfoot varus deformities. Shifting the calcaneal tuberosity laterally (lateralization) can lead to tarsal tunnel pressure increase and tibial nerve palsy. The purpose of this cadaveric biomechanical study was to investigate the correlation of lateralization and pressure increase underneath the flexor retinaculum.MethodsThe pressure in the tarsal tunnel of 12 Thiel-fixated human cadaveric lower legs was measured in different foot positions and varying degrees of calcaneal lateralization.ResultsThe mean pressure increased from plantarflexion (PF) to neutral position (NP) and from NP to hindfoot dorsiflexion (DF), and with increasing amounts of lateralization of the calcaneal tuberosity. The mean baseline pressure in PF was 1.5, in NP 2.2, and in DF 6.5 mmHg and increased to 8.1 in PF, 18.4 in NP, and 33.1 mmHg with 12 mm of lateralization. The release of the flexor retinaculum significantly lowered the pressure.ConclusionIncreasing pressures were found in the tarsal tunnel with increasing lateralization of the tuberosity and with both dorsiflexion and plantarflexion of the ankle.Clinical relevanceA pre-emptive release of the flexor retinaculum for a lateralization of the calcaneal tuberosity of more than 8 mm should be considered, especially if specific patient risk factors are present. No tibial nerve palsy should be expected with 4 mm of lateralization.

Tarsal tunnel release restores sensations in sole for diabetic sensorimotor polyneuropathy.

Project description:BackgroundDiabetic sensorimotor polyneuropathy (DSPN) is the commonest form of neuropathy. Loss of sensations in sole leads to diabetic foot ulcers (DFU) and its complications. Surgical decompression has been used in the treatment of diabetic peripheral neuropathy, however; its effectiveness has been questioned.Purpose of this study was to evaluate the sensory recovery in sole after tarsal tunnel decompression (TTD) in patients having DSPN.MethodsThirteen patients (Age28-70 years, average 35.57 years; 7 Males, 6 Females; 20 feet) with DSPN and positive Tinel's sign over the tarsal tunnel were included in the study. Pre and post-operative sensory tests performed on the sole included tests for touch, pain, temperature, pressure, vibration perception threshold (VPT) and two-point discrimination (2-PD). Results were classified as per British Medical Research Council (MRC) scoring system.Results-Sixteen feet were followed-up for 6 months. In all feet perception of touch, pain and pressure recovered. Temperature perception recovered in 75% feet. VPT came to normal range (16.81V) from 40.37 V and 2-PD came down to average of 6.0 mm from preoperative average of11.2 mm.MRC scale improved from S0 in 5 feet and S2 in 15 feet to S3+ in all 16 feet.There were no ulcers or amputation in operated limbs during follow up period of 6 months.ConclusionsTTD improves plantar sensations in diabetic neuropathy and prevents ulcers and its related complications.

Tarsal tunnel syndrome in the mucopolysaccharidoses: A case series and literature review.

Project description:BackgroundThe mucopolysaccharidoses (MPS) are a group of inherited, progressive, multi-system lysosomal storage disorders. Musculoskeletal manifestations include nerve entrapment syndromes, most commonly carpal tunnel syndrome. Tarsal tunnel syndrome (TTS) has also been reported. The purpose of this study was to investigate the clinical course of MPS patients with suspected TTS and to conduct a literature review of TTS in MPS.MethodsA review of the Medline and EMBASE databases was conducted in accordance with published guidelines from the Joanna Briggs Institute of Evidence Based Medicine with search strategy developed by a librarian trained in systematic reviews. A medical record review was undertaken for all patients managed in the multi-disciplinary MPS clinic in a tertiary referral paediatric centre, identifying patients with a suspected or established diagnosis of TTS. Data regarding the demographics, investigations, presentation, management, and clinical course were collected.ResultsThe literature review failed to identify any published papers regarding TTS in MPS, with conference proceedings only identified. Within a cohort of 19 MPS patients, four patients with a suspected diagnosis of TTS were identified (MPS I: two patients, MPS VI: two patients). Three patients underwent surgical tarsal tunnel decompression, two with good result. One patient had overlapping symptoms with spinal stenosis and improvement in suspected tarsal tunnel symptoms following spinal decompression and fusion.
