Postural control and torque of the knee joint after healed tibial shaft fracture

Muscular atrophy occurs as a consequence of trauma and immobilisation. This cohort comparison study was conducted to evaluate the limb function after healed tibial shaft fractures, which were treated by casting versus nailing. Balance (as centre of pressure) and muscle strength (as torque of the knee joint during knee extension) have been measured in 27 patients with tibial shaft fractures with a mean age of 39 (19–73) years, 1 year after fracture healing. Fourteen patients were treated by intramedullary nailing ‘nailed group’ and 13 by plaster cast with or without minimal internal fixation ‘casted group’. Centre of pressure was measured on a force platform. Knee extension torque was measured during isometric and concentric muscle actions by an isokinetic dynamometer. Centre of pressure tended to be more towards the uninjured leg in patients who had been treated by plaster cast ( P
