Functional outcome of the minimally invasive plate osteosynthesis for the supracondylar fractures of femur using dynamic condylar screw

ABSTRACT

To assess the functional outcomes of minimally invasive plate osteosynthesis [MIPO] for the extra-articular and undisplaced intra-articular supracondylar fractures of femur using dynamic condylar screw [DCS]. Descriptive case series. Department of Orthopaedic Surgery, Jinnah Postgraduate Medical Centre Karachi, from April 2009 to October 2011. Patients were enrolled from accident and emergency and OPD. OPD follow-ups were carried out at 2nd, 6th, 12th, 18th, and 24th weeks, then every 2nd month for the assessment of rate of union and range of motion of knee joint. A total of 83 patients were included. There were 55 males and 28 females. Male to female ratio was 1.961. Patients were 25-50 year of age. Seventy four [89.2%] of the injuries were caused by road traffic accident and 9 [10.8%] due to fall from height. Forty six [55.4%] patients had fractures on right side and 37 [44.6%] on left side. Radiological union was achieved in 79 [95.2%] patients at an average period of 19.05 weeks. The radiological bony union was achieved in 16-18 weeks in 25[30.1%] patients. Four patients developed nonunion for which bone graft from iliac crest was placed after 24 weeks. Two achieved union in one year follow up while two were lost to follow up. At end of one year, forty-three [51.8%] cases had knee flexion from zero to 90° - 120°, 25 [30.1%] cases had knee flexion of > 120° and remaining 15 [18.1%] cases had knee flexion of <90°. At the end of one year satisfactory [knee motion > 90°] functional outcome as achieved in 68 [81.9%] cases. High rates of both radiological union [95.2%] and satisfactory [knee motion > 90°] functional outcome [81.9%] were achieved in large number of cases
