title: [How much are external fixator nuts tightened in general practice].
abstract: External fixation is an approved system of treatment in orthopedic surgery. 21 different modalities of assembly--using the AO (ASIF) tubular system--were selected for a clinical trial in 3 major trauma hospitals. It is considered that all nuts of the applied external fixators were tightened properly. In experimental work it was found, that a torque of 8-11 Nm is sufficient and can be recommended. A suitable torque-wrench is available.
