We have used arthroscopic debridement and interposition arthroplasty with an acellular dermal matrix allograft in treatment of first carpometacarpal joint arthritis successfully in a limited number of patients. The purpose of this investigation was to study the use of an acellular dermal matrix graft in a rabbit model of interposition arthroplasty. Eleven rabbits underwent excision of the lunat...

Posttraumatic radioulnar synostosis (RUS) is a rare event following forearm fractures. Consequences are disabling for patients who suffer from functional limitation in forearm pronosupination. Distal RUS are even more rare and more difficult to treat because of high recurrence rates. The patient we describe in this paper came to our attention with a double distal RUS recurrence and a Darrach pr...

BACKGROUND/AIMS To investigate if restoration of esophago-intestinal or esophago-gastric continuity with a jejunal pouch after total or proximal gastrectomy has clinical benefits. METHODS We reviewed all relevant reports published after 1990 that dealt with the clinical results of reconstruction with a jejunal pouch after total and proximal gastrectomies and correlated those findings with res...

From 1974 to 1988, six children with fistula recurrence following primary tracheoesophageal fistula (TEF) repair have been managed at our hospital. Reclosure of the fistula with pleural flap interposition was used as the initial corrective procedure in five patients, with an 80% incidence of second TEF recurrences. Due to these discouraging results, we have abandoned this technique and instead ...

BACKGROUND Conventional wisdom suggests that vascular interposition flaps are helpful in the treatment of all patients with vesicovaginal fistulas. Complicated fistulas are often treated with interposition omental flaps; however, failed omental flap repairs have not been described without the use of another interposition flap. CASE A 52-year-old woman with a history of cystotomy repair at the...

We present this case because of its rarity, as we have not found anything similar in young non-neoplastic patients. We describe the case of a 36 years-old woman with long-term dysphagia for solids. Her past medical history reveals an esophagoplasty with subcutaneous colon interposition, which was performed in Romania 15 years before, due to caustic stricture. Stenosis of the cologastric anastom...

Stomach is considered the “gold standard” as an esophageal substitute after esophagectomy. Reflux disease is considered an unavoidable consequence of esophageal resection followed gastric interposition. Reflux esophagitis shows a progression from inflammation to erosions and to the development of columnar lined metaplasia. With the use of a gastric interposition, the most popular option to reco...

Enclaves, such as those enabled by Intel SGX, offer a hardware primitive for shielding user-level applications from the OS. While enclaves are useful starting point, code running in enclave requires additional checks whenever control or data is transferred to/from untrusted The enclave-OS interface on however, can be extremely large if we wish to run existing unmodified binaries inside enclaves...
