Background: Previous studies have shown good clinical results in patients with midshaft clavicular fractures treated reconstruction plate fixation or elastic stable intramedullary nailing. The objective of this study was to compare these methods terms and radiographic results. Methods: In prospective, randomized controlled trial, fifty-nine displaced were randomly assigned receive either a (thirty-three patients), known as the group, nailing (twenty-six nail group. primary outcome six-month...

To compare the functional results of carpectomy and four-corner fusion surgical procedures for treating osteoarthrosis following carpal trauma.In this prospective randomized study, 20 patients underwent proximal row or to treat wrist arthritis their were compared. The midcarpal joint was free lesions in all patients.Both reduced pain. All had a decreased range motion after surgery. differences between groups not statistically significant.Functional two similar as both pain with scapholunate...

ABSTRACT Objective: Compare the formation of symptomatic neuromas in patients submitted to digital amputations, with and without nerve conduits (Neurolac® ), sensitivity return. Methods: Prospective, case-control study, including 14 amputations (total 17 fingers) whose were used on ulnar or radial side, while contralateral side was same as control. The Tinel test, Semmes-Weinstein monofilament, two-point discrimination tests evaluated at one week, two weeks, month, three months, six months...

Abstract Posterior tibial tendon (PTT) dysfunction is recognized as an etiology leading to acquired flatfoot in adults, causing significant functional loss. Many risk factors and systemic conditions have been proposed literature. However, many patients present PTT without any of these characteristics. This suggests that there could be a genetic influence associated with posterior tendinopathy. The purpose the study investigate association −1607 polymorphism promoter gene MMP‐1 test group...

The purpose of this study was to observe whether the results median nerve fascicle transfer biceps are equivalent classical ulnar transfer, in terms elbow flexion strength and donor morbidity. Twenty-five consecutive patients were operated between March 2007 July 2013. divided into two groups. In Group 1 (n = 8), received an motor branch. 2 15), a Two with follow-up less than six months excluded. Both groups similar regarding age (P 0.070), interval injury 0.185), period 0.477). Elbow...

Historically, the dorsal arterial system of hand received less attention than palmar system. The studies concerning anatomy present some controversies regarding origin and presence metacarpal artery branches. Knowledge arteries is especially applied in surgical planning for flaps taken from dorsum hand. purpose this study to analyze hand, compare our observations with those previous literature, therefore define parameters supplied by arteries.Twenty-six dissections were performed at right 26...

Posterior tibial tendon is particularly vulnerable and responsible for much morbidity in sportspersons. Some patients have a predisposition without clinically recognized cause, suggesting that individual characteristics, inclusive genetic inheritance, play an important role tendinopathy. Matrix metalloproteinase ( MMP )‐8 proteinase capable of degrading large amount extracellular proteins, influence degradation remodeling collagen. To determine whether the −799 polymorphism promoter ‐8 gene...

The authors analyzed 14 patients with severe osteomyelitis of the upper extremity between 1985 and 1992, managed vascularized fibular graft. Eleven radii, two humeri one ulna were reconstructed. Bone loss after resection ranged from 6 to 12 cm (mean 8.14 cm). Follow-up 8 months 7 years 10 3 months). therapeutic applications graft in bone infections discussed good results this surgical procedure established it as a option for treatment. Morbidity at donor site was minimal.

Abstract Background: Since the first experiments with fibrin glue application in microvascular anastomoses 1977, several studies have reported its benefits on suture reduction and anastomosis decreased time. In spite of that, clinical experience has been limited to two neurosurgical replantation case series, all them good results. This study was conducted evaluate feasibility potential free flaps. Methods: We performed 24 flaps patients, from March 2005 June 2006. Twenty were included this...

We describe a new technique for removing the distal fragments of broken intramedullary femoral nails without disturbing nonunion site.This involves application an AO distractor prior to removal nail fragments, with subsequent proximal fragment in anterograde fashion and through medial parapatellar approach. Impaction fracture site is then performed that broader than remaining fragmented material.Nails were removed from five patients using described above any complications. After mean...

This study aimed to investigate the social and hospital costs of patients treated at a public who were motorcycle crash victims.This prospective was on 68 riders (drivers or passengers), followed up from admission 6 months after crash. A questionnaire covering quantitative qualitative questions administered.Motorcycle victims responsible for 12% institution's admissions; 54.4% young (18-28 years age); 92.6% drivers; 91.2% male; 50% used their motorcycles as daily means transportation. Six...

The purpose of this report is to critically evaluate our results two intercostal nerve transfers directly the biceps motor branch in complete traumatic brachial plexus injuries. From January 2007 November 2012, 19 patients were submitted type surgery, but only 15 them had a follow-up for ≥2 years and included report. mean interval from trauma surgery was 6.88 months (ranging 3 9 months). Two intercostals nerves dissected transferred branch. 38.06 24 62 Ten (66.6%) recovered an elbow flexion...

Microvascular anastomosis is the most critical step during free flap transfers or replantations. Although conventional suture still considered standard technique, it technically difficult, time consuming, and traumatic to vessel wall. The aim of this study was evaluate effectiveness fibrin adhesive overcome these problems when applied in microvascular anastomosis.Sixty-eight Wistar rats were used study. Eight animals a pilot determine minimum amount stitches required per applied. In...

Objective: This is a clinical study of our experience using pedicle perforator flaps to cover skin defects in the middle and distal segment leg. Design: Prospective study. Setting: University hospital. Patients/Intervention: Twenty-four patients underwent treatment defect or leg by means pedicled based on perforating arteries. The arteries were located before operation echo-Doppler examination. planned propeller fashion (21 cases) as advancement (three cases). Main Outcome Measurements:...

Abstract The authors reviewed 62 neurotizations of the brachial plexus in 71 patients performed between 1974 and 1989. nerves used were accessory, motor or sensory branches cervical plexus, intercostals. Twenty‐five suprascapular nerves, 19 musculocutaneous, 4 medial roots median nerve, 12 lateral nerve neurotized. concluded that useful results can be achieved using extraplexual neurotizations. © 1994 Wiley‐Liss, Inc.

Abstract Background: Several studies have already reported the utilization of fibrin glue in microvascular anastomoses to minimize number sutures and decrease operative time. Despite good results obtained most these experiments, its clinical application has not launched. The aim this study was clarify controversies around safeness anastomoses, also demonstrate potential benefits a realistic free flap model. Methods: Twenty‐seven rabbits were used study. experimental model consisted groin...
