<p class="abstract"><strong>Background:</strong> Trochanteric fracture is the commonest fracture which accounts to 90 % of the fractures in patients over 50 years. The aim of the treatment is to prevent malunion and early mobilization with ambulation which is accomplished by dynamic hip screw and sliding plate. Minimal invasive technique has advantages of less blood loss, minimal soft tissue dissection, early mobilization and shorter hospital stay<span lang="EN-IN">.</span>The study was done to evaluate the amount of intraoperative blood loss, reduction of postoperative haemoglobin, requirement of postoperative analgesics and duration of postoperative hospital stay in the patients with stable intertrochanteric fracture treated with minimal invasive dynamic hip screw (MIDHS).</p><p class="abstract"><strong>Methods:</strong> Twenty five patients with stable intertrochanteric fractures were treated with minimal invasive Dynamic hip screw fixation. Average intra operative blood loss, reduction of postoperative haemoglobin, requirement of post-operative analgesics and total duration of postoperative hospital stay were evaluated. All the patients were followed up periodically at 6 weeks, 3 months, 6 months, 1 year.  All the patients were evaluated radiologically in the follow up period. The functional assessment was done with Harris hip score.<strong></strong></p><p class="abstract"><strong>Results:</strong> Mean intraoperative blood loss was found to be 75 ml. The mean duration of surgery was found to be 44.3 minutes. All the patients were mobilized 24 hours of surgery with non-weight bearing walking with walker support. The average time for union was found to be 4 months. No complications like postoperative infection, malunion, coxa vara, limb length discrepancy were seen. The final functional Harris hip score was found to be excellent in 14, good in 4, fair in 2<span lang="EN-IN">. </span></p><p class="abstract"><strong>Conclusions:</strong> MIDHS is a safe technique having advantages of less blood loss, minimal soft tissue dissection and shorter hospital stay, early rehabilitation in treating stable intertrochanteric fractures compared to conventional DHS<span lang="EN-IN">.</span></p>

Floating Knee is the term applied to the flail knee joint segment resulting from a fracture of the shaft or adjacent metaphysis of the ipsilateral femur and tibia The fractures range from simple diaphyseal to complex articular types. The word floating knee was introduced for the first time by Mc Bryde in 1965. The incidence of these injuries is increasing. They are associated with potentially life threatening injuries of the head, chest, and abdomen. Not less frequently these injuries cause infection, excessive blood loss, fat embolism, mal union, delayed or non-union, knee stiffness, prolonged hospitalization, and inability to bear weight. Malunion is one complication which drastically affects the functional outcome. Hence we tried to find the factors that may result in malunion more often than not which will help to prepare us in a more suitable manner in treating these injuries We analysed 30 cases of floating knee which were surgically treated regarding the pattern of injuries, type of injuries, closed/open, fixation methods, associated injuries, union rates, malunion and functional outcome. All cases were followed up to a minimum of 1 year. We found that malunion in a floating knee injury which was surgically treated drastically affected functional outcome. The mechanism of injury, type of fracture, open/closed injury, level of fracture whether diaphyseal or juxta articular or intraarticular, type of initial fixation all had a significant correlation with occurrence of malunion.
