A spring-loaded, impact-type chiropractic device especially useful for repositioning a cervical vertebra in the spinal column of a patient. The device includes a tubular casing having an anvil structure at one end and a spring-biased hammer mounted in the tubing. An elongated spindle is connected to the hammer for drawing the hammer away from the anvil into a loaded position in which the spring is compressed. A releasable detent mechanism is provided which holds the hammer in the loaded position or, when released, allows the hammer to strike the anvil. Preferably, the casing includes two telescopically-interfitted tubular portions and one or more hammer-biasing springs; adjustment of the tubular portions relative to each other determines the amount of compression of the springs with the hammer in the loaded position. With the anvil structure adjacent the back of a patient, the device allows the chiropractor to precisely regulate the amount of impacting force transmitted to the patient's back and to accurately direct the blow to reposition a vertebra.
