<p class="abstract"><strong>Background:</strong> The acetabular quadrilateral fractures are difficult to treat and ORIF using a spring plate buttressing the quadrilateral surface underneath an iliopectenial plate in a 90-90 construct. The aim of the study was to assess the clinical and radiological outcome, success rate and proportion of the post-operative complications of surgical management of comminuted quadrilateral plate acetabulum fractures after ORIF.</p><p class="abstract"><strong>Methods:</strong> It was a hospital based descriptive type of observational study conducted in the Department of Orthopedics, SMS Medical College. The data collection was done from May 2016 up to June 2018. The sample size was 31 for the study purpose, at 95% confidence limits and 20% relative allowable error.<strong></strong></p><p class="abstract"><strong>Results: </strong>We studied 31 patients of communited quadrilateral plate fractures, who were evaluated preoperatively and optimized. ORIF was performed. The mean blood loss was 450 ml and the mean operating time was 130 minutes. The patients were followed up at 1 year postoperatively where 24 patients had an excellent to good Harris Hip clinical score and 24 patients had an excellent to good Matta radiological score, and both were found to be statistically significant.</p><p><strong>Conclusions:</strong> Comminuted quadrilateral plate fractures of the acetabulum are managed surgically by ORIF using a spring buttressing plate beneath the infrapectenial plate. The clinical and radiological follow up for one year duration scores showed good scores which were statistically significant, indicating the success of quadrilateral fixation using this technique. </p>
<p class="abstract"><strong>Background: </strong>Infected non-union of tibia and femur is a debilitating disorder for patient as well as challenging task for treating surgeon. Conventionally treatment of infected non-union is a two staged procedure. But antibiotic cement-impregnated intramedullary nailing (ACIINs) is a single staged and cost-effective procedure. Hence we intended to study the outcome of ACIIN use in infected non-union of tibia and femur.</p><p class="abstract"><strong>Methods:</strong> This is a hospital based prospective case series type of descriptive study conducted in Department of Orthopedics, SMS Medical College and Hospital, Jaipur. We studied 35 cases of infected non-union of femur and tibia fracture with interlock nail in situ. All patients were treated with interlock nail removal, debridement and freshening of sclerosed bony ends and fixation with ACIIN. All were followed for at least 6 months for infection control and bony union and final results were evaluated by Paley’s bony criteria and functional criteria.<strong></strong></p><p class="abstract"><strong>Results:</strong> Infection was controlled in 94.28% cases. Bony union was achieved in 88.57% cases (19 femur and 12 tibia). Average duration for bony union was 7.3 months for femur and 8 months for tibia. According to Paley’s criteria for bony outcome and functional outcome 65.71% and 51.43% had shown excellent outcome respectively.</p><p class="abstract"><strong>Conclusions:</strong> ACIIN is a good modality for treatment of infected non union of tibia and femur in terms of infection control and bony union and has a good functional outcome when bone gap is less.</p>
