Potential injury to the common peroneal nerve at the level of the fibula head/neck junction during fine wire insertion in stabilization of proximal fibula, is a recognised complication. This study aims to relate the course of the common peroneal nerve to fibula head transfixion wire. Standard 1.8mm Ilizarov wires were inserted percutaneously in the fibula head of cadaveric knees. The course of the common peroneal nerve was dissected calculating wire to nerve distance.Background:
Methods:
Septic arthritis following intra-capsular penetration of the knee by external fixation devices is a complication of traction/fixation devices. This study aimed to demonstrate the capsular attachments and reflections of the distal femur to determine safe placements of wires. The attachments of the capsule to the distal femur were measured in cadaveric knees. Medially and laterally measurements were expressed as percentages related to the maximal AP diameter of the distal femur.Background:
Methods:
Total radiation exposure accumulated during circular frame treatment of distal tibial fractures was quantified in 47 patients treated by a single surgeon from March 2011 until Nov 2014. The radiation exposures for all relevant radiology procedures for the distal tibial injury were included to estimate the radiation risk to the patient. The median time of treatment in the frame was 169 days (range 105 – 368 days). Patients underwent a median of 13 sets of plain radiographs; at least one intra operative exposure and 16 patients underwent CT scanning. The median total effective dose per patient from time of injury to discharge was 0.025 mSv (interquartile range 0.013 – 0.162 and minimum to maximum 0.01–0.53). CT scanning is the only variable shown to be an independent predictor of cumulative radiation dose on multivariate analysis, with a 13 fold increase in overall exposure.Methods:
