In the field of research, the growth of data mining using the k-means technique is well accepted, which involves the extraction of data from datasets with some limitations. To overcome the drawback of this technique we employed the kernel concepts and resolved the cluster inadequacy of separability. We have proposed an optimization technique to include a fisher’s discriminant analysis into the kernel of particle swarm optimization concept with GA (Genetic Algorithm) to evaluate fitness function. The fitness function value is required to select offspring for the next generation. The consequence was to reduce the noise and enhance the performance of clustering. The GA (Genetic Algorithm) was employed to optimize the objective of the fitness function by providing the input parameter. The kernel technique performs more fault identification features than principal component analysis. Results found are more beneficial by this method like fitness value, stopping criteria, and the average distance between individuals. In this research paper, we discuss the comparative analysis with the objective function of k-means and kernel fisher’s discriminant analysis in the domain of the large dataset. The fitness value of proposed KFDA is smaller than k-means fitness.

Aim: The aim of this study to evaluate the functional outcome of scaphoid non-union treated with bone grafting and Herbert screw fixation.
Material and Methods: This study was done the Department of Orthopaedics, Anugrah Narayan Magadh Medical College and Hospital, Gaya, Bihar, India for 15 months. 50 cases were referrals from peripheral centers with a possible diagnosis of scaphoid non-union after failed conservative treatment. 50 patients were initially assessed with fresh radiographs and MRI wrist was taken in all cases. The injuries were classified according to Herbert’s Classification. Clinical examination included the assessment of tenderness, active and passive range of movement in wrist, and grip strengths were also measured. A firm padded removable splints were used to support the wrist for the first two weeks and after the suture removal, patients are advised to start mobilizing exercises of the wrist.
Results: There were 50 cases of scaphoid non-union treated with Herbert screw fixation and cancellous bone grafting. All the patients were males and dominant hand was involved in 45 cases. Out of 50 patients 22 patients had road traffic accidents, 25 had fall on outstretched hand and 3 fracture caused by assault. The right wrist was affected in 42 cases and left in 8 patients. The mean time from injury to surgical fixation was 15 months. The mean age of the patients was 28.5 years. Our study resulted in 60% excellent, 30% good and 10% fair functional outcomes. 98% of patients were satisfied with the outcome of the procedure mostly because they could return to job with a painless joint. Most of our patients had moderate to severe pain preoperatively, but 86% cases had no pain at the latest review.
Conclusion: We concluded that the healing of the non-union is better than that in other surgeries like k wire fixation or bone graft surgeries alone.
