To demonstrate experience of bone transport arthrodesis of the knee with simultaneous lengthening in the treatment of infected peri-articular fracture fixation associated with large condylar defects. Four patients (3 male/1 female), mean age 46.5 years (37–57 y) with post-traumatic osteomyelitis involving the knee were treated by radical debridement, removal of all metalwork and frame application. Substantial condylar defects resulted (6–10 cm) with loss of extensor mechanism. Parenteral antibiotics were administered for several weeks. Two patients required muscle flaps. Bone transport was utilised to achieve an arthrodesis whilst simultaneously lengthening. In three cases a ‘peg in socket’ construct was fashioned to ensure stability of the arthrodesis.Purpose
Methods
Accurate and reproducible radiological assessment of shoulder replacement prostheses over time is important for identifying failure or to provide reassurance. A number of clearly defined radiological parameters have been described to help standardise the radiological assessment of prostheses. To our knowledge, this is the first study conducted to test the reproducibility and reliability of these measurements. The aim of this work was to test intraobserver reproducibility and interobserver reliability in the measurement of humeral component orientation (HCO), humeral head offset (HHO), humeral head size (HHS), humeral head height (HHH), and acromiohumeral distance (AHD.)Background
