We describe in 30 feet the occurrence of a tarsal tunnel syndrome caused by a ganglion. The presenting symptom was numbness or pain in the toes and the sole with paraesthesiae in the distribution of the medial plantar nerve in 63% of the patients. Swellings which were not palpable were detected by ultrasonography. Twenty-nine patients were treated by operation. Most ganglia originated from the talocalcaneal joint, and five were associated with a talocalcaneal coalition. The surgical outcome was satisfactory in all patients except one who had a further operation for a recurrence of the ganglion. (+info)
Neurovascular decompression for idiopathic tarsal tunnel syndrome: technical note.
(2/24)
OBJECTIVE: The surgical outcome of idiopathic tarsal tunnel syndrome (TTS) is reported to be worse than that attributable to ganglion, tarsal coalition, or tumour, and therefore further development in the surgical treatment for idiopathic TTS is considered to be necessary. Here the efficacy of neurovascular decompression for patients with idiopathic TTS is evaluated. METHODS: Twelve feet from nine patients with idiopathic TTS were treated. The patients were aged 52-78 years (mean 64.6 years), and all of them complained of pain or dysaesthesia of the sole of the foot. The posterior tibial nerve was freed from the attached arteriovenous complex (posterior tibial artery and veins). The dissected nerve had a flattened appearance in all of the patients, suggesting nerve compression by the adjacent arteriovenous complex and superficially by the flexor retinaculum. A graft of fat was inserted as both a cushion and an antiadhesive between the vessels and the nerve to achieve neurovascular decompression. RESULTS: Patients on whom neurovascular decompression was performed had resolution or lessening of symptoms in their feet. Neither wound infection nor recurrence of symptoms was found during the follow up period (mean 26.8 months). CONCLUSION: Neurovascular compression syndrome plays a part in idiopathic TTS, and adding neurovascular decompression to resection of the flexor retinaculum is effective. (+info)
Tarsal tunnel syndrome - the effect of the associated features on outcome of surgery.
(3/24)
Between 1989 and 2000, 16 patients underwent surgery for tarsal tunnel syndrome; 12 patients (13 feet) were available for follow-up at a mean of 83 (12-143) months. The symptoms had resolved in six feet, were improved in four, were unchanged in two and recurred after five years in one. Better results are obtained in patients who have space occupying lesions than in those in whom the aetiology is idiopathic or post-traumatic or those with foot deformities. (+info)
The tarsal tunnel syndrome after a proximal lesion.
(4/24)
Three patients in whom the first symptoms of the tarsal tunnel syndrome (TTS) emerged after an acute event proximal to but not affecting the ankle are described. These patients suggest that a pre-existing asymptomatic TTS may become manifest after a mechanism akin to that described in the "double crush" syndrome. (+info)
Diagnosing heel pain in adults.
(5/24)
Heel pain is a common condition in adults that may cause significant discomfort and disability. A variety of soft tissue, osseous, and systemic disorders can cause heel pain. Narrowing the differential diagnosis begins with a history and physical examination of the lower extremity to pinpoint the anatomic origin of the heel pain. The most common cause of heel pain in adults is plantar fasciitis. Patients with plantar fasciitis report increased heel pain with their first steps in the morning or when they stand up after prolonged sitting. Tenderness at the calcaneal tuberosity usually is apparent on examination and is increased with passive dorsiflexion of the toes. Tendonitis also may cause heel pain. Achilles tendonitis is associated with posterior heel pain. Bursae adjacent to the Achilles tendon insertion may become inflamed and cause pain. Calcaneal stress fractures are more likely to occur in athletes who participate in sports that require running and jumping. Patients with plantar heel pain accompanied by tingling, burning, or numbness may have tarsal tunnel syndrome. Heel pad atrophy may present with diffuse plantar heel pain, especially in patients who are older and obese. Less common causes of heel pain, which should be considered when symptoms are prolonged or unexplained, include osteomyelitis, bony abnormalities (such as calcaneal stress fracture), or tumor. Heel pain rarely is a presenting symptom in patients with systemic illnesses, but the latter may be a factor in persons with bilateral heel pain, pain in other joints, or known inflammatory arthritis conditions.

Ultrasonography in tarsal tunnel syndrome.
(6/24)
OBJECTIVE: The purpose of this study was to clarify the diagnostic value of ultrasonography in tarsal tunnel syndrome. METHODS: Seventeen patients (17 feet) with tarsal tunnel syndrome were treated between 1988 and 2003. Preoperative ultrasonography was performed, and the cause of the syndrome was confirmed intraoperatively in all cases. Long and short axes of the tarsal tunnel were scanned to ascertain the presence of any space-occupying lesion. RESULTS: The causes of tarsal tunnel syndrome, as confirmed by surgery, were ganglia (n = 10), talocalcaneal coalition (n = 1), talocalcaneal coalition associated with ganglia (n = 3), and varicose veins (n = 3). Among the cases involving ganglia, hypoechoic or anechoic regions were observed. The mean sizes +/- SD of these regions were 19.4 +/- 8.8 mm in the long axis, 15.2 +/- 6.3 mm in the short axis, and 10.4 +/- 3.8 mm in depth. Of these, 3 ganglia were not clearly palpable before surgery and were small: 10 x 10 x 7, 13 x 11 x 9, and 9 x 8 x 7 mm. Among the cases involving talocalcaneal coalition, ultrasonography indicated a beak-shaped bony process on the short axis images. Although these 3 cases were associated with ganglia, this could not be determined by preoperative palpation. CONCLUSIONS: As a diagnostic imaging technique for tarsal tunnel syndrome, ultrasonography is extremely useful for identifying space-occupying lesions. Ultrasonography should be performed routinely in patients with suspected tarsal tunnel syndrome. (+info)
Anterior tarsal tunnel syndrome.
(7/24)
We have reviewed 10 patients treated for anterior tarsal tunnel syndrome produced by compression of the deep peroneal nerve or its branches, and we have studied the anatomy of the tunnel in 25 adult feet. The causes of onset of the syndrome included contusion of the dorsum of the foot, tight shoe laces, talonavicular osteophytosis, ganglion, and pes cavus. The clinical signs were often diagnostic but electromyography was helpful. Operative decompression in nine feet of eight patients gave successful results at 1.5 to 4 years follow-up. (+info)
Tarsal tunnel syndrome caused by a talocalcaneal joint amyloidoma in a long-term haemodialysis patient: a case report.
(8/24)
We present a case of tarsal tunnel syndrome caused by an amyloidoma arising from the talocalcaneal joint in a 64-year-old man with a long history of haemodialysis. He presented with numbness in the medial plantar area of the right foot without any antecedent trauma. The numbness was minimal at rest but gradually worsened, causing difficulty, when walking. Paraesthesia was present on the medial sole of the right foot. A positive Tinel-like sign was noted 2.5 cm below the medial malleolus. Magnetic resonance imaging demonstrated a round lesion, 1 cm in diameter, in the calcaneus, which was hypointense on T1-weighted images and hyperintense on T2-weighted images. In addition, a mass, 1 cm in diameter with a signal isointense to that of muscle was found adjacent to the talocalcaneal joint. The medial plantar nerve was decompressed after removing a solid, 1-cm diameter mass from the talocalcaneal joint. At 6 months post surgery, the numbness had completely resolved. No recurrence was observed at the 24-month follow-up. (+info)
