Musculoskeletal and neuromuscular conditions of instrumental musicians.
Performing Arts Medicine is a broad field that includes the study of medical conditions and injuries incurred by dancers, instrumental musicians, and vocalists. This article summarizes the most relevant literature of approximately the past 10 years concerning the musculoskeletal and neuromuscular conditions of musicians. A literature search was done for relevant articles in English by physicians or scientists. Some older, but fundamental, articles are included; incidental case reports were excluded to the extent possible. Included were articles on incidence, prevalence, pathophysiology, diagnosis, treatment, and biomechanical studies in musicians. Although nearly all of these conditions are the same ones seen in the general work force, it is clear that their occurrence patterns in the professional musician are unique, as is their impact on the life and livelihood of the patient. The content of the Arts Medicine literature does not permit a truly critical review. Research in the last 10 years appears not to have been done in a true blinded, random case-controlled fashion. Many authors support their statements with only their respective clinical experiences. The research cited here includes 58 series, 9 case studies, 5 surveys, 2 pre/post intervention studies, and 1 double-blind crossover clinical trial.

Spinal needle damage during routine clinical practice.
This study investigated whether the tips of spinal needles are damaged during the process of spinal anaesthesia by impact on bone, by repeated attempts at performing the block or by the use of an introducer. Used spinal needles from five different hospitals were carefully resheathed after use and a questionnaire completed. The needles were examined under a light microscope with the observer unaware of the questionnaire data. Two hundred and twenty-two needles were examined, of which 36 were damaged. Five unused control needles of each type were also examined and all were found to be undamaged. There was no significant difference between the damaged and undamaged used needles with respect to impacts on bone or the number of attempts. Pajunk 24G Sprotte needles were significantly less likely to sustain damage when the integral introducer was used as compared to an alternative introducer.
