STATISTICS OF AMPUTATIONS.

asymptotic property of order statistics and sample quntile

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...

Prosthetics / Amputations

The technique of hydrogen clearance has been used in five canines to monitor blood flow in gastrocnemius muscle following sympathectomy. The contralateral nonsympathectomized limb was used as a control . Average blood flow was based on 22 pairs of desaturation data . Average blood flow in the left control limb was 6.08 ± 2 .22 ml/min/100g tissue and the right sympathectomized limb was 9.54 ± 3 ...

Transmetatarsal and Midfoot Amputations

The objective of lower extremity amputation surgery is to create a viable, functional residual limb to maximize patient mobility and independence. When part or all of the forefoot is lost to trauma, infection or gangrene, and the hindfoot is viable, every attempt should be made to preserve as much foot function as possible. The use of the transmetatarsal level is common. In the past, amputation...

Limb Amputations in Western

Over a period of five years, 123 patients who had 124 limb amputations in King Fahd Hospital, Jeddah, Western Saudi Arabia were reviewed to find out the pattern of amputations, aetiological factors and difficulties in management. The male: female ratio was 2.8 : 1. The mean age was 52.5 years (range, 2·100 yrs). The lower limb was involved in 108 cases (87.8%) compared to only 16 upper limb amp...
