METHODS In this retrospective study, we reviewed the results of pectoralis major repair in 11 chronic cases(> 6 wk) done between September 2011 and December 2014 at our institute. In all cases repair was done by same surgeon using corkscrew suture anchors and box suture sliding technique. At 6 mo, after surgery magnetic resonance imaging was done to see the integrity of the repair. Functional evaluation was done using Penn and ASES scores. Pre and postoperative Isokinetic strength was measured.RESULTS Average follow-up was 48.27 ± 21.0 mo. The Wilcoxon signed rank test was used to evaluate the outcome scores. The average ASES score increased from an average of 54.63 ± 13.0 preoperatively to 95.09 ± 2.60 after surgery at their last follow-up. The average Penn score also increased from 5.72 ± 0.78, 2.81 ± 1.32 and 45.81 ± 1.72 to 9.36 ± 0.80, 8.27 ± 0.90 and 59 ± 1.34 for pain, satisfaction and function respectively. Follow up magnetic resonance imaging(MRI)(at 6 mo) showed continuity and the bulk of pectoralis major muscle in all cases. Average isokinetic strength deficiency in horizontal adduction at 60° was 13.63% ± 6.93% and at 120° was 10.18% ± 4.93% and in flexion at 60° was 10.72% ± 5.08% and at 120° was 6.63% + 3.74%. Results showed that both ASES and Penn score improved significantly(2 tailed P value = 0.0036).CONCLUSION We could conclude from this series that pectoralis major repair even in chronic cases using 5.5 mm corkscrew anchors give excellent functional and cosmetic results. In chronic cases the repairable length of the tendon is not available and sliding suture technique allows for fixation of worn out tendomuscular junction to bone without letting cutting through the muscle.展开更多

A retrospective study (2006-2010) was conducted by reviewing clinical records of dogs treated for cranial cruciate ligament injury with an extra-articular repair method using anchors preloaded with Fiberwire. A questionnaire was given to owners for evaluation of their dog’s performance prior to surgery and at time of follow-up with a minimum of 12 months post-operative. Owner assessment was rated using a visual analogue scale. Completed questionnaires from 34 owners were received. The mean time to follow up was 27.5 months. Owner assessment of their dog prior to surgery versus at the time of follow up were considered significant (P < 0.001) in regards to quality of life, willingness to play voluntarily, activity level, stiffness at the beginning and end of the day, lameness in the surgical limb, and pain while walking on the surgical limb. These results indicate that extra-articular stabilization with Arthrex Corkscrew and FASTak anchors placed at near isometric sites are adequate repair methods for cranial cruciate ligament rupture.展开更多

Therefore a linear system is derived. After a transformation of it the calculation of radius and center can be separated from each other. The remaining linear system for the center of the insphere can be solved after discovering the inverse of the corresponding coefficient matrix. This procedure can also be applied in the planar case to determine radius and center of the incircle of a triangle.展开更多
