BACKGROUND Scant attention has been paid to breast capsule revision after augmentation mammaplasty. Dissatisfaction with traditional techniques prompted the senior authors to develop a thermal capsulorrhaphy (TC) technique to obliterate excess breast pocket space using ball cautery followed by barbed suture closure. OBJECTIVES The authors propose a new periprosthetic technique for pocket clos...

Eighty-one cemented total hip arthroplasties in patients younger than 45 years were reviewed with an average 9.2-year follow-up interval. The results were compared with the same group previously reported at an average follow-up time of 4.5 years. Clinically satisfactory results were 58% compared with 78% at 4.5 years. The revision rate almost tripled to 33%. Impending failure was present in 56%...

PURPOSE Congenital ptosis is a troubling eye condition for pediatric ophthalmologists. There are many considerations to contemplate when deciding when to operate and which technique to use. METHODS A retrospective chart review of 69 pediatric patients treated for congenital ptosis using a double rhomboid frontalis sling with a nylon suture at a single tertiary care center. RESULTS For patie...

Due to enormous resource consumption, model checking each revision of evolving systems repeatedly is impractical. To reduce cost in checking every revision, contextual assumptions are reused from assumeguarantee reasoning. However, contextual assumptions are not always reusable. We propose a fine-grained learning technique to maximize the reuse of contextual assumptions. Based on fine-grained l...

Removing well-fixed acetabular components can be a challenge for orthopaedic surgeons in revision of total hip arthroplasty. Acetabular bone loss, fracture, and other complications occurred in extracting implants may result in instability and fail of revision. Thus, instruments are developed to avoid such complications. We report a simple technique by drilling a tunnel on the superolateral quad...

| We present a new approach to the problem of revising extended programs, based on the coherence theory initially advocated by Gardenfors for belief revision. Our approach resolves contradiction by removing only connict-ing information, not the believed source of it, and therefore , keeps information loss minimal. Furthermore, since there is no need of searching for problematic assumptions, as ...

Removal of hardware in orthopaedic surgery is usually encountered in revision fracture surgery for non union, mal union, infection and peri-implant failure. If the hardware has broken this can make revision surgery even more demanding. Numerous techniques have been described to facilitate implant removal. A broken femoral nail is not an uncommon presentation of a delayed union or a non union. W...

There have been a number of publications in recent years on generalising the AGM paradigm to the Horn fragment of propositional logic. Most of them focused on adapting AGM contraction and revision to the Horn setting. It remains an open question whether the adapted Horn contraction and Horn revision are interdefinable as in the AGM case through the Levi and Harper identities. In this paper, we ...
