RESUMEN
There is currently an increased interest in the use of electro surgery in arthroscopy. Since the introduction of the bipolar arthroscopic radiofrequency (RF) wand, it has started to replace the classic Bovie monopolar probe on the assumption that the new technology provides multifunctional devices, combining both tissue removal and haemostasis into one instrument. The more efficient tissue ablation and precise haemostasis achieved with these instruments should result in a significant reduction in the operative time and cost. We ran a prospective comparative randomised study to test this hypothesis. Forty patients underwent arthroscopic subacromial decompression, randomised into two groups. The group treated with bipolar RF was associated with an average operative time saving of 8 min (P < 0.0001) and an average cost saving of pound 83 (euro 111) per case (P < 0.003), compared to monopolar RF. Bipolar RF is the instrument of choice in arthroscopic shoulder surgery, as it saves time and money.

A case of locking of a metacarpo-phalangeal joint in a 47-year-old woman is reported. Full movement of the joint was restored after excision of a haemangioma which had arisen from the volar plate. Other causes of locking are described and recommendations for treatment are made.

A 10-year-old boy who sustained a fracture through a cyst in the ulna later developed a pseudarthrosis. During 13 years' follow-up the characteristic short bowed forearm developed but, instead of the more usual spontaneous dislocation of the head of the radius, the patient also developed the previously unreported complication of osteoarthritis of the elbow.
