Perfusion imaging is the aspect of functional imaging, which is most applicable to the musculoskeletal system. In this review, the anatomy and physiology of bone perfusion is briefly outlined as are the methods of acquiring perfusion data on MR imaging. The current clinical indications of perfusion related to the assessment of soft tissue and bone tumors, synovitis, osteoarthritis, avascular necrosis, Keinbock's disease, diabetic foot, osteochondritis dissecans, and Paget's disease of bone are reviewed. Challenges and opportunities related to perfusion imaging of the musculoskeletal system are also briefly addressed...

INTRODUCTION: Kienbock's disease is an osteonecrosis of lunate bone (lunatomalacia) seen more commonly in males in the second to fourth decade of life. The exact etiology is unknown and symptoms include wrist pain and stiffness of wrist. Advanced stages of disease may require lunate excision and filling of the void by various substitutes like silicone implants, tendon grafts etc. We report a case of Kienbock's disease with lunate excision and filling of defect by coiled palmaris longus muscle and tendon unit...

The etiologies of Keinböck's disease and intraosseous ganglion remain unknown. Both entities are rare and the coexistence of these two pathologies in the same patient and hand is even less frequent. We report the case of a 40-year-old man with a longstanding history of martial arts practice (karate) who developed an avascular necrosis of the lunate concomitant with a giant intraosseous ganglion of the scaphoid bone successfully managed by proximal row carpectomy. We review the literature of these two diseases...

Midcarpal hemiarthroplasty is a novel motion-preserving treatment for radiocarpal arthritis and is an alternative to current procedures that provide pain relief at the expense of wrist biomechanics and natural motion. It is indicated primarily in active patients with a well-preserved distal row and debilitating arthritic symptoms. By resurfacing the proximal carpal row, midcarpal arthroplasty relieves pain while preserving the midcarpal articulation and the anatomic center of wrist rotation. This technique has theoretical advantages when compared with current treatment options (i...

Roentgen ray epilation, which is at present the most important single weapon against M. audouini infection of the scalp, should not be withheld except in special circumstances, from a child who has the disease. It can quickly cure the disease and halt spread from one child to another. Harmful sequelae and medicolegal complications can be averted by competent use of the method and simple precautions. The Keinbock-Adamson technique of epilation can be recommended without hesitancy, provided it is carried out meticulously in every detail, and administered by an operator of suitable training and experience in roentgen therapy of the skin...

The incidence of post-surgical complete A-V block has come down from 16% in the 50's to less than 1% with improvement in technique. Of these, 14% are transient and attributable to post-operative oedema and haemorrhage at the site of block. Permanent damage manifests early, or as late as 15 years, and in these, the risk of sudden death is a reality. Phrenic paralysis has been attributed to inadvertent pinching, cutting, traction on the phrenic nerve, and has been noticed after pericardiectomy, Blalock-Hanlon operation, Mustard repair, performance of a Blalock-Taussig shunt or closure of ASD...
