Bone pain after transplantation is a frequent complication that can be caused by several diseases. Treatment strategies depend on the correct diagnosis of the pain. Nine patients with severe pain in their feet, which was registered after transplantation, were investigated. Bone scans showed an increased tracer uptake of the foot bones. Magnetic resonance imaging demonstrated bone marrow oedema in the painful bones. Pain was not explained by other diseases causing foot pain, like reflex sympathetic dystrophy, polyneuropathy, Morton's neuralgia, gout, osteoporosis, avascular necrosis, intermittent claudication, orthopaedic foot deformities, stress fractures, and hyperparathyroidism. The reduction of cyclosporine- or tacrolimus trough levels and the administration of calcium channel blockers led to relief of pain. The Calcineurin-inhibitor Induced Pain Syndrome (CIPS) is a rare but severe side effect of cyclosporine or tacrolimus and is accurately diagnosed by its typical presentation, magnetic resonance imaging and bone scans. Incorrect diagnosis of the syndrome will lead to a significant reduction of life quality in patients suffering from CIPS.

Joint and soft tissue injection of the ankle and foot region is a useful diagnostic and therapeutic tool for the family physician. This article reviews the injection procedure for the plantar fascia, ankle joint, tarsal tunnel, interdigital space, and first metatarsophalangeal joint. Indications for plantar fascia injection include degeneration secondary to repetitive use and traumatic injuries that are unresponsive to conservative treatment. Diagnostic aspiration or therapeutic injection of the ankle or first metatarsophalangeal joints can be performed for management of advanced osteoarthritis, rheumatoid arthritis, and other inflammatory arthritides such as gout, or synovitis or an arthrosis such as "turf toe." Persistent pain and disability resulting from tarsal tunnel syndrome, an analog of carpal tunnel syndrome of the wrist respond to local injection therapy. A painful interdigital space, such as that occurring in patients with Morton's neuroma, is commonly relieved with corticosteroid injection. The proper technique, choice and quantity of pharmaceuticals, and appropriate follow-up are essential for effective outcomes.

Non-infectious soft tissue lesions of the foot and ankle are relatively rare clinically. These include benign and malignant neoplasms, as well as non-neoplastic or pseudotumoral lesions such as ganglionic, synovial and epidermoid cysts, intermetatarsal and adventitious bursitis, inflammatory lesions like gouty tophi and rheumatoid nodules, Morton's neuroma, and granuloma annulare. A 48-year-old male with a history of medically treated tophaceous gout presented with left foot neuropathic pain and paresthesia, in the setting of a well-circumscribed soft tissue lesion of the second intermetatarsal space, suspected to be a Morton's neuroma. Magnetic resonance imaging (MRI) showed a 4.1 x 2.7 x 2.6 cm heterogeneous soft tissue mass containing multiple cystic areas. Excisional biopsy was performed and histologic examination revealed well-circumscribed nodules of amorphous material containing needle-shaped clefts, rimmed by histiocytes, and multinucleated giant cells consistent with a gouty tophus. This is the first case reported in the literature of an intermetatarsal gouty tophus causing neuropathic pain and paresthesia. While Morton's neuroma is the most common cause of this presentation, this case illustrates that other pseudotumoral lesions, such as a gouty tophus, may present similarly, and should be considered in the differential diagnosis. While most cases of tophaceous gout can be adequately treated with urate-lowering therapy, surgery may be indicated for tophi that do not resolve with medical treatment based upon symptom severity, compression of nearby structures, and functional impairment.
