A three-part retrospective study was undertaken to review the long-term results of surgical treatment trigger finger.Seventy-five patients were identified by chart review.Fifty-nine these assessed a telephone survey, with mean follow-up period 48 months (range, 6-70 months).Forty-six (78%) underwent physical examination.Surgical successful in all patients.Ninety-seven percent had complete resolution triggering, and rest significant improvement symptoms.The recurrence rate 3%, only single...
PURPOSE To assess the long-term efficacy of embolotherapy in combination with surgery for management symptomatic high- flow arteriovenous malformations (HFAVMs) lower and upper extremities. MATERIALS AND METHODS Twenty consecutive patients high-flow extremity AVMs (LE-AVMs; n = 9) (UE-AVMs; 11) were treated from 1982 to 1999. All nine LE-AVM had pain seven ulceration skin. 11 UE-AVM debilitating pain, weakness affected hand, two bony erosion. Embolization nidus beneath site maximum or was...
In determining ideal anthropomorphic values of the female breast, previous studies relied on aesthetic judgments 1 plastic surgeon alone or conveyed no judgment.Anthropomorphic measurements were recorded from breasts 109 volunteers. Images their arranged into a computerized survey, and surgeons, cosmetic breast surgery patients, reconstructive patients interviewed for feedback.In all, 252 15 25 submitted 4446 evaluations. The sternal notch to nipple distance was 21 21.5 cm, base 6...
There has been little discussion in the published literature regarding breast shape preferences. This study was conducted to ascertain previously undocumented differences preferences between plastic surgeons and patients seeking augmentation, with respect upper-pole contour. Sixty-six respondents, grouped into three cohort categories (plastic surgeons, augmentation patients, lay people), were asked evaluate a series of 12 nonptotic profiles representing range contours. Five exhibited convex...
Background There has been little discussion in the plastic surgery literature regarding breast shape preferences among surgeons, despite strong evidence that such aesthetic are influenced by multiple factors. Much effort focused on delineating objective criteria which an “attractive” might be defined. This study aimed at providing a better understanding of presence and significance differences personal perception, how these relate to surgeon’s demographic, ethnic, cultural background, as...
The limited availability of donor sites for nerve grafts and their inherent associated morbidity continue to stimulate research toward finding suitable alternatives. In the following study, effect direct administration growth factor (NGF) into a conduit across gap was tested in rat sciatic model. A 1-cm segment right Sprague-Dawley rats resected, then bridged using one three methods: group I (NGF-treated group, n = 12), vein graft filled with NGF (100 ng 0.3-ml phosphate buffered saline); II...
Surgical delay is an effective technique, but the precise timing of effect and required extent procedure are uncertain. We endeavored to study [Illegible Text] survival as a function duration period in rat transverse rectus abdominis myocutaneous (TRAM) flap model. Two specific procedures (limited extensive) were utilized, was assessed after periods 3, 7, 10, 14, 21, 30 days (n ≥ all groups). A 7 or greater resulted statistically significant improvement groups. The appeared be maximal at 14...
The short-term outcomes of pediatric digit replantation have been derived primarily from single-center/surgeon experience. purpose this study was to conduct a nationwide analysis and trends as compared adult patients.Digit patients were identified in the 1999-2011 Healthcare Cost Utilization Project, Nationwide Inpatient Sample. Outcomes included in-hospital procedure-related total complications, microvascular revision, amputation, length stay (LOS). Univariate multivariate analyses...
Previous work on critical ischemia time suggested (1) a greater susceptibility of myocutaneous flaps over skin to the reperfusion injury and (2) that duration may affect survival area flap. Using pig model, 55 animals were operated times patterns buttock (n = 85) latissimus dorsi 88) island determined after being submitted 0, 2, 4, 6, 8, 10, 12, 14, 16 hours normothermic ischemia. The average (CIT50) be 9 10 for flaps, respectively. Percentage total surviving (%TAS) in those which did...
Purpose. Congenital anomalies and injuries of the hand are often undertreated in low-middle income countries (LMICs). Humanitarian missions to LMICs commonplace, but few exclusively surgery have been reported none attempted demonstrate their cost-effectiveness. We present first study evaluating cost-effectiveness a humanitarian mission Honduras as method reducing global burden surgically treatable disease. Methods. Data were collected from San Pedro Sula, Honduras. Costs estimated for local...
Background: Breast shape is largely determined by the volume of tissue and surface area skin envelope. Values for breast have never been published in literature. The investigators developed an inexpensive, noninvasive optical method to objectively measure area, its accuracy determined. Methods: An grid projected onto breast, two images are captured create a computerized three-dimensional model from which volume, maximum vertical projection calculated. Results: To assess accuracy, simple...
The dye fluorescence index (DFI) has been cited as an accurate predictor of skin-flap survival. However, two thresholds, one each for flap survival and necrosis, have advocated. A DFI less than 15 to 20 percent predicts failure, a greater 35 50 Values indicate uncertain outcome. present study was undertaken (1) determine the optimum threshold prediction in pigs, (2) compare dermofluorometry with blood flow measured by radioactive microspheres. Dermofluorometry found be (90 percent)...
Patients undergoing free tissue transfer are particularly susceptible to hypothermia. The goal was investigate the impact of intraoperative core body temperature on flap thrombosis. Two hundred twelve cases reconstruction at Yale-New Haven Hospital between 1992 and 2008 were reviewed. Free thrombosis defined by complete necrosis or direct visualization arterial venous Temperature measurements calibrated bladder temperatures as measured Foley catheter sensor. Through logistic regression...
Abstract The lateral arm free flap (LAFF) has been chosen by some head and neck reconstructive microsurgeons to be their fasciocutaneous of choice. qualities this have suggested include its consistent vascular anatomy, thin pliable nature, reinnervation capabilities, as well low donor site morbidity ease closure. During the past year we performed 14 reconstructions using extended LAFF (ELAFF). We present our indications for use review shortcomings. Although ELAFF does limitations, including...
The single-pedicled transverse rectus abdominis musculocutaneous (TRAM) flap is prone to partial loss and fat necrosis, especially in high-risk groups such as patients who smoke, irradiated patients, obese patients. Possible methods increase the reliability of TRAM include free TRAM, double-pedicled surgically delayed TRAM. When we traveled overseas an underserved area were largely unable implement these options due limitations equipment, supplies, length our trip. We encountered a combined...
Previous work in our laboratory has indicated that ischemic preconditioning improves musculocutaneous flap survival 2.5 times of the control area when flaps are subsequently subjected to 4 hours global ischemia. The protocol used this study was arbitrarily designed be 10 minutes pedicle clamping followed by reperfusion. This sequence repeated for three cycles with a total time 1 hour. There no published works comparing different protocols flaps. goal determine if cycle and number influenced...
In the clinical management of combined tendon and nerve injuries, there are competing treatment strategies. Isolated injuries should be rapidly mobilized after repair to prevent adhesion formation, whereas isolated repairs usually immobilized disruption allow axon regrowth. Recommendations in published literature for vague advise up 3 weeks immobilization. The goals this study were determine which length gap resulted rupture a following postoperative mobilization with modified Duran protocol...
Background: Polydactyly is the most common congenital hand deformity. There currently no consensus among pediatricians or surgeons regarding optimal management of ulnar (post-axial) type B polydactyly leading to uncertainty in initial treatment decisions for infants with this Methods: Parents newborns were enrolled a prospective, nonrandomized trial from 2010 2012. At enrollment they offered: 1) treatment, 2) suture ligature, 3) immediate excision under local anesthesia, and 4) delayed at...
