A variety of surgical procedures exist for repair of both traumatic and degenerative osseous and soft-tissue pathologic conditions involving the foot and ankle. It is necessary for the radiologist to be familiar with these surgical procedures, so as to assess structural integrity, evaluate for complicating features, and avoid diagnostic pitfalls. Adequate interpretation of postoperative changes often requires access to surgical documentation to evaluate not only the surgery itself but the expected timeline for resolution of normal postoperative changes versus progressive disease...

OBJECTIVE: To assess, utilizing MRI, tarsal tunnel disease in patients with talocalcaneal coalitions. To the best of our knowledge, this has only anecdotally been described before. MATERIALS AND METHODS: Sixty-seven ankle MRIs with talocalcaneal coalition were retrospectively reviewed for disease of tendons and nerves of the tarsal tunnel. Interobserver variability in diagnosing tendon disease was performed in 30 of the 67 cases. Tarsal tunnel nerves were also evaluated in a control group of 20 consecutive ankle MRIs...

Intraneural ganglion cysts in the tarsal tunnel are rare. We present a patient who had an intraneural ganglion cyst involving the medial and lateral plantar and distal tibial nerves. Magnetic resonance imaging revealed evidence to support the joint-related (i.e., subtalar) origin of the cyst. Careful reinterpretation of the imaging supported a phasic mechanism (i.e., cross-over) to explain the interrelated pathogenesis of the intraneural cyst within the three nerves. This mechanism is analogous to that described for the prototypes-the peroneal, tibial and sciatic nerves in the knee region-and can be generalized to other nerves in the foot and ankle region...

Osteochondroma or exostosis is the most common benign bone tumor, and occurring frequently in the proximal humerus, tibia, and distal femur. It rarely affects talus. Osteochondroma of talus is a very rare etiology of tarsal tunnel syndrome (TTS). We report a rare case of extensive osteochondroma of the talus in a 60 year old female presenting with multiple swellings around the ankle and symptoms suggestive of tarsal tunnel syndrome. En-block excision of the multiple masses was done. Histopathological examination confirmed the diagnosis of osteochondroma...

BACKGROUND: Lateralizing calcaneal osteotomy (LCO) is a frequently used technique to correct hindfoot varus deformity. Tibial nerve palsy following this osteotomy has been described in case reports but the incidence has not been quantified. METHODS: Eighty feet in 72 patients with cavovarus foot deformity were treated over a 6-year span by 2 surgeons at their respective institutions. Variations of the LCO were employed for correction per surgeon choice. A retrospective chart review analyzed osteotomy type, osteotomy location, amount of translation, and addition of a tarsal tunnel release in relation to the presence of any postoperative tibial nerve palsy...

BACKGROUND: Tarsal tunnel syndrome is a known complication of lateralizing calcaneal osteotomy. A Malerba Z-type osteotomy may preserve more tarsal tunnel volume (TTV) and decrease risk of neurovascular injury. We investigated 2 effects on the tarsal tunnel of the Malerba osteotomy compared to a standard lateralizing osteotomy using a cadaveric model: (1) the effect on TTV as measured by magnetic resonance imaging (MRI) and (2) the proximity of the osteotomy saw cuts to the tibial nerve...

OBJECTIVE: Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the posterior tibial nerve in the tarsal tunnel. It is not known whether vascular or neuropathic factors are implicated in the cause of a cold sensation experienced by patients. Therefore, we studied the cold sensation in the pedal extremities of patients who did or did not undergo TTS surgery. METHODS: Our study population comprised 20 patients with TTS (38 feet); 1 foot was affected in 2 patients and both feet in 18 patients...

Heterotopic ossification has been reported to occur after musculoskeletal trauma (including orthopedic procedures). This has been known to cause nerve entrapment syndromes and persistent pain, limiting joint mobility. We present a case of a 19-year old female collegiate athlete who had previously undergone ankle arthroscopy and arthrotomy to remove 2 ossicles. At approximately 1 year postoperatively, the patient developed pain when planting and pivoting her foot. Imaging revealed a radiodense lesion at the posteromedial ankle consistent with heterotopic ossification and entrapment of the tibial nerve within the tarsal tunnel...

PURPOSE: Many patients with diabetes mellitus (DM) experience numbness in the extremities. This DM neuropathy may be complicated by peripheral entrapment neuropathy. We prospectively investigated the cause(s) of limb numbness in DM patients. MATERIALS AND METHODS: We enrolled 23 patients with uni- or bilateral limb numbness who were treated in our DM clinic. They were 10 men and 13 women; their average age was 63 years. The average duration of their neurological symptoms was 28...

This case illustrates the complexity and interrelationship of osseous pathology with peripheral nerve entrapment and neuromata. She had an iatrogenic nerve injury of a branch of the medial dorsal cutaneous nerve causing her painful scar. Secondarily, she developed an injury to her common peroneal nerve from the cast immobilization, resulting in palsy/drop foot. The tarsal tunnel entrapment was likely a sequela of the cast immobilization and chronic swelling. Her postoperative chronic pain was compounded by the failure to use grommets with the polymeric silicon (Silastic) implant at the initial surgery, leading to a breakdown of the implant with subsequent detritic synovitis...

Tarsal tunnel syndrome is defined as an extrinsic and/or intrinsic compressive neuropathy of the posterior tibial nerve or one of its branches. Its causes include venous insufficiency. Clinical case: 51 year-old female patient from León, Guanajuato. Hypertensive, with Guillain-Barré syndrome for eight years, vascular insufficiency and obesity. Her condition started with left ankle and heel pain; she was treated with NSAIDs and rehabilitation and achieved partial improvement. X-rays and MRI of the left ankle showed posterior impingement...

BACKGROUND: Both vascular and compression etiologies have been proposed as the source of neurologic symptoms in tarsal tunnel syndrome. Advancing the understanding of the arterial anatomy supplying the posterior tibial nerve (PTN) and its branches may provide insight into the cause of tarsal tunnel symptoms. The purpose of this study was to describe the arterial anatomy of the PTN and its branches. METHODS: Sixty adult cadaveric lower extremities (thirty previously frozen and thirty fresh specimens) were amputated distal to the knee...

BACKGROUND: No epidemiological studies on the prevalence of compressive neuropathy have been undertaken in Arab countries. The aim of the study was to estimate the prevalence of the most common types of compressive neuropathies in Qena governorate/Egypt. METHODS: The study was part of a community-based survey carried out to assess the prevalence of neuromuscular disorders among the Qena population. A random sampling of 10 districts, 5,039 inhabitants aged ≥20...

AIMS: Knowledge about branching pattern of the popliteal artery is very important in any clinical settings involving the anterior and posterior tibial arteries. This study aims to elucidate the anatomical variation patterns and common types of anterior tibial artery (ATA) and posterior tibial arteries (PTA) in the general population in China. MATERIAL AND METHODS: Anatomical variations of ATA, PTA, and peroneal artery were evaluated with ultrasound in a total of 942 lower extremity arteries in 471 patients...

OBJECTIVE: To present a case report of bilateral posterior tarsal tunnel syndrome (PTTS) caused by an accessory flexor digitorum longus (AFDL), including the surgical technique and a review of the literature. MATERIALS AND METHODS: Twenty-nine year old male diagnosed with bilateral PTTS, refractory to conservative management, with 53 points on the preoperative AOFAS score. MR of both ankles showed an AFDL within the tarsal tunnel, in close relationship to the posterior tibial nerve...

INTRODUCTION: Tarsal tunnel syndrome (TTS) arises from tibial nerve damage under the flexor retinaculum of the fibro-osseus tunnel at the medial malleolus. It is notoriously difficult to diagnose, as many other foot pathologies result in a similar clinical picture. We examined the additional value of nerve ultrasound in patients with tarsal tunnel syndrome confirmed by nerve conduction. METHODS: We performed a retrospective analysis of nerve ultrasound changes in electrophysiologically confirmed TTS spanning our records from 2007 to 2015...
