Purpose: To compare results from our surgical treatment experiences in children with obstetric brachial plexus injuries (OBPI), to those who have had other surgical treatments. Methods: We conducted a retrospective study in our medical records consisting of two groups of OBPI patients. Group 1: 26 OBPI children (16 girls and 10 boys), age range between 2.0 and 12.0 (mean age 6.9), who have undergone surgical treatments at other institutions between 2005 and 2010. Group 2: 45 OBPI children (20 boys and 25 girls), age between 0.7 and 12.9 (mean age 3.7), who have had modified Quad and triangle tilt surgical treatment between 2005 and 2010 at our institution. In both groups Mean modified Mallet scores and radiological scores were measured and compared. All measurements were made at least one year post surgery in both groups. Results: Post-operative mean modified Mallet score was 11.8 ± 2.4 in group 1 patients, whereas post-mean modified Mallet score was 20 ± 2.7 (P 0.0001) following modified Quad and triangle tilt surgeries in group 2 patients. Further, their radiological scores such as posterior subluxation, and glenoid version were 13.4 ± 21.3 and ﹣30.2 ± 19.1 in group 1, whereas 32.1 ±13.5 (P 0.0004), and ﹣16.3 ± 11.5 (P 0.008) in group 2 patients, when compared to normal values of 50, and 0 respectively. Conclusion: Patients who have had mod Quad and triangle tilt for OBPI obtained significantly better functional outcomes in modified total Mallet score as well as in radiological scores, when compared to those OBPI children, who underwent other procedures such as posterior glenohumeral capsulorrhaphy, biceps tendon lengthening, humeral osteotomy, anterior capsule release, nerve transfer/graft, botox and muscle/tendon transfer and release.

This paper proposes a new approach for solving the bearings-only target track.ng (BoT) problem by introducing a maximum correntropy criterion to the pseudolinear k.lman filter (PLk.). PLk. has been a popular choice for solving BoT problems owing to the reduced computational complexity. However, the coupling between the measurement vector and pseudolinear noise causes bias in PLk.. To address this issue, a bias-compensated PLk. (BC-PLk.) under the assumption of Gaussian noise was formulated. However, this assumption may not be valid in most practical cases. Therefore, a bias-compensated PLk. with maximum correntropy criterion is introduced, resulting in two new filters: maximum correntropy pseudolinear k.lman filter (MC-PLk.) and maximum correntropy bias-compensated pseudolinear k.lman filter (MC-BC-PLk.). To demonstrate the performance of the proposed estimators, a comparative analysis assuming large outliers in the process and measurement model of 2D BoT is conducted. These large outliers are modeled as non-Gaussian noises with diverse noise distributions that combine Gaussian and Laplacian noises. The simulation results are validated using root mean square error (RMSE), average RMSE (ARMSE), percentage of track.loss and bias norm. Compared to PLk. and BC-PLk., all the proposed maximum correntropy-based filters (MC-PLk. and MC-BC-PLk.) performed with superior estimation accuracy.
