Minimal Invasive Ostheosintesis For Treatment Of Diaphiseal Transverse Humeral Shaft Fractures

Objective: To evaluate patients with transverse fractures of the shaft of the humerus treated with indirect reduction and internal fixation with plate and screws through minimally invasive technique. Methods: Inclusion criteria were adult patients with transverse diaphyseal fractures of the humerus closed, isolated or not occurring within 15 days of the initial trauma. Exclusion criteria were patients with compound fractures. Results: In two patients, proximal screw loosening occurred, however, the fractures consolidated in the same mean time as the rest of the series. Consolidation with up to 5 degrees of varus occurred in five cases and extension deficit was observed in the patient with olecranon fracture treated with tension band, which was not considered as a complication. There was no recurrence of infection or iatrogenic radial nerve injury. Conclusion: It can be concluded that minimally invasive osteosynthesis with bridge plate can be considered a safe and effective option for the treatment of transverse fractures of the humeral shaft.

Survival Rates Of The Himex Extensible Nail In The Treatment Of Children With Osteogenesis Imperfecta

Objective: To evaluate the performance of an extensible nail with hooks, named HIMEX, in osteogenesis imperfecta (OI) deformities. Methods: All child patients were operated on with HIMEX from 1990 to 2004. The number of fractures, reappearance of deformities, improvement of motor development before and after the use of HIMEX, and the incidence of the migration and nail survival were compared. Results: Fourteen patients, with ages from 2 to 18 years, including 8 females, underwent 46 procedures, 39 primary and 7 re-operations. The average age at the first fracture was 148.21 days, and there was an average of 42.6 fractures per patient prior to HIMEX placement. Of the forty-six bones affected, 28 were femurs and 18 were tibias. Average follow-up care lasted 80.21±36.71 months. There was a statistically significant decrease (0.78) in the number of fractures per patient and an improvement in walking in seven of the fourteen patients. Revision occurred in 18% of patients and migration of the nail occurred in 12% (5/39). Eighty percent of the nails remained in situ until 108 months, with femoral procedures lasting significantly longer than tibial procedures. The type of OI and the age at the procedure did not significantly affect the incidence of revision. Conclusion: HIMEX significantly reduced the number of fractures, presenting lower incidence of migration and higher survival rates than those described in literature.186343348Sofield, H.A., Millar, E.A., Fragmentation, realignment, and intramedullary rod fixation of deformities of the long bones in children.

Bridging plate osteosynthesis of humeral shaft fractures

This study was approved by the Ethics Committee of the Faculty of Medical Sciences and developed during November 2000 and July 2001 in the Orthopedic and Traumatology Department of UNICAMP. There were 15 patients, 11 mates, age between 14 and 66 years. All fractures were unilateral. Of the 15 patients eight were polytraumatised, two of them had open fractures. The others had an isolated fracture of the humerus, of which one was open. None of the patients had previous lesions of the radial nerve, but in two patients there was a lesion of the brachial plexus. All of the patients underwent a bridging plate osteosynthesis of the humeral shaft fractures using only two small incisions proximal and distal to the fracture site. We used broad or narrow D.C.P.(R) plates for large fragments mostly with 12 holes, fixed with two or three screws at each end. All cases united with an average time of 8-12 weeks, with the exception of one case with a grade III open fracture and a brachial plexus lesion on the same side. We had no major complications. All patients recovered good function of the limb without significant residual deformity. (C) 2004 Elsevier Ltd. All rights reserved.35658759

Scaphoid Fracture Nonunion: Correlation Of Radiographic Imaging, Proximal Fragment Histologic Viability Evaluation, And Estimation Of Viability At Surgery: Diagnosis Of Scaphoid Pseudarthrosis

Purpose: The purpose of this study was to correlate the pre-operative imaging, vascularity of the proximal pole, and histology of the proximal pole bone of established scaphoid fracture non-union. Methods: This was a prospective non-controlled experimental study. Patients were evaluated pre-operatively for necrosis of the proximal scaphoid fragment by radiography, computed tomography (CT) and magnetic resonance imaging (MRI). Vascular status of the proximal scaphoid was determined intra-operatively, demonstrating the presence or absence of puncate bone bleeding. Samples were harvested from the proximal scaphoid fragment and sent for pathological examination. We determined the association between the imaging and intra-operative examination and histological findings. Results: We evaluated 19 male patients diagnosed with scaphoid nonunion. CT evaluation showed no correlation to scaphoid proximal fragment necrosis. MRI showed marked low signal intensity on T1-weighted images that confirmed the histological diagnosis of necrosis in the proximal scaphoid fragment in all patients. Intra-operative assessment showed that 90 % of bones had absence of intra-operative puncate bone bleeding, which was confirmed necrosis by microscopic examination. Conclusions: In scaphoid nonunion MRI images with marked low signal intensity on T1-weighted images and the absence of intra-operative puncate bone bleeding are strong indicatives of osteonecrosis of the proximal fragment.3916772Chang, M., Bishop, A., Moran, S., The outcomes and complications of 1,2-intercompartmental supraretinacular artery pedicled vascularized bone grafting of scaphoid nonunions (2006) J Hand Surg [Am], 31, pp. 387-396Dias, J., Brenkel, I., Finlay, D., Patterns of union in fractures of the waist of the scaphoid (1989) J Bone Joint Surg, 71B, pp. 307-310Compson, J., The anatomy of acute scaphoid fractures.

A case series featuring extremely short below-knee stumps

Background: Lower limb amputations should be evaluated carefully, especially with regard to the possibility of preserving the knee joint to enable a more physiological gait and lower energy consumption. Below-knee amputations were performed immediately below the tibial tuberosity with maintenance of the insertion of the patellar tendon, resulting in very short, but functional stumps. This case study examined whether very short below-knee stumps allow a more functional gait, as compared to more proximal amputations. Case Description and Methods: Between June 2010 and June 2011, four patients had extremely short below-knee amputations, with resection of the head of the fibula at the junction and reinsertion of the collateral ligaments and structures attached to the tibia. This was followed by placement of a prosthesis with a vacuum-assisted suspension socket. Findings and Outcome: At the end of treatment, patients that underwent transtibial amputations with an extremely short stump were considered well adapted to their prosthesis and were satisfied in relation to the acquired gait patterns. Conclusion: The extremely short below-knee amputation, despite having a short lever arm should be considered as another option for lower-limb amputations, although we cannot yet assure that other patient groups undergoing this level of amputation may have the same results of the study.36223623

Is MIPO in humeral shaft fractures really safe? Postoperative ultrasonographic evaluation

In the last few years there has been great interest in minimally invasive plate osteosynthesis (MIPO) in the treatment of humeral shaft fractures. None of these studies showed the anatomical relationship between the radial nerve and the material of the implant in vivo. We performed postoperative ultrasonographic measurement of the distance between the radial nerve and the material implanted using the MIPO technique. Nineteen patients underwent postoperative ultrasound examinations. Group A comprised midshaft fractures and group B distal third fractures. The point of greatest proximity between the radial nerve and the implant was measured. In group A the distance was between 1.6 and 19.6 mm (mean: 9.3 mm) and in group B between 1.0 and 8.1 mm (mean: 4.0 mm). The ultrasound findings reveal that the radial nerve is quite close to the implant material, especially in the transition between the third and fourth quarters of the humeral shaft
