No full textPeripheral Nerve Defects Overviews of Practice in Europe
No full textMany surgical techniques are available for the repair of peripheral nerve defects. Autologous nerve grafts are the gold standard for most clinical conditions. In selected cases, alternative types of reconstructions are performed to fill the nerve gap. Non-nervous autologous tissue based conduits or synthetic ones are alternatives to nerve autografts. Allografts represent another new field of interest. Decision making in the treatment of nerve defects is based on timing of referral, level of the injury, type of lesion, and size of any gap. This review focuses on current clinical practice, influenced by the numerous new experimental researches
Nerve transfers in distal forearm and in the hand
Full text linkNerve transfers were used, originally, to restore shoulder and elbow function in brachial plexus lesions. This concept has been developed over the years and applied to distal nerve injuries in which lower functionality was expected because of the gap between the injury site and the target muscle. The aim of this review is to describe nerve transfers in the distal forearm and hand for isolated lesions of the median, ulnar and radial nerves. The different advantages achieved by transposition of a functional nerve stump near the effector muscle have opened up new options for the management of nerve lesions. Some of these alternatives have only been recently reported and a few are exclusively case reports

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textCorrelation between risk factors and healing times in long bone nonunions treated with corticoperiosteal flap from the medial femoral condyle
No full textBackground: The rate of fracture nonunion varies depending on the anatomical site. Numerous procedures have been proposed to treat recalcitrant nonunions. The vascularized medial femoral condyle corticoperiosteal free flap (MFCCFF) is increasingly used in nonunions with small bone loss.The percentage of success of the MFCCFF is high but the factors involved in delayed bone healing or failure of this technique or the contraindications are not described in the literature.This multicentric study aims to identify and report the different factors involved in determining the time of bone healing in the treatment of atrophic nonunion of long bones with the vascularized medial MFCCFF. Methods: All patients who underwent vascularized medial MFCCFF from January 2011 to December 2020 for the treatment of recalcitrant atrophic nonunions of long bones. Patients were reviewed at 2 and 6 weeks, and 3, 6, and 12 months postoperatively and evaluated by physical and radiographic examinations and patient-reported outcome measures. Results: The final study population comprised 59 patients with a mean follow-up of 26.2 ± 7.6 months, a rate of bone healing of 94.9% with a mean radiographic bone healing time of 4.1 ± 1.3 months, and low morbidity of the donor site. Diabetes mellitus, a body mass index (BMI) ≥30 kg/m2, and ≥2 previous surgeries on the fracture site were factors predicting timing for bone healing at the multivariate analysis. Conclusion: This study demonstrates the MFCCFF as an effective and safe procedure for the treatment of the recalcitrant atrophic nonunion of long bones. An association was found between the lengthening of bone healing time and a high BMI, presence of ≥2 previous surgical interventions, and diabetes mellitus, indicating these comorbidities as risk factors (not absolute contraindications) for this microsurgical treatment. So, to our knowledge, the MFCCFF could be the first-choice treatment for atrophic nonunion of long bones
Functional and subjective results of 20 thumb replantations
No full textThe aim of this retrospective study was to analyse the results of 20 thumb replantations with special and exhaustive attention on functional outcomes. Twenty patients with traumatic thumb amputation were enrolled in the study. Range of motion, grip strength, sensory recovery, and subjective perception of overall hand function recovery were measured. The average age at the time of surgery was 35 years (range, 13-73 years). The mean follow-up was 3.25 years (range, 1.9-10.25 years). The long-term results of thumb replantation confirmed satisfactory outcomes in terms of general upper limb function, handgrip and pinch strength, and social and work reintegration. Sensory recovery remained unsatisfactory despite the fact that we did not need to perform any kind of revision surgery as a consequence of inadequate thumb sensibility. For the first time in the existing literature, no functional parameter that contributes to the assessment of the function of replanted thumbs has been excluded. We resume in the same study the analysis of all functional parameters that are useful to define results of thumb replantation. (C) 2012 Elsevier Ltd. All rights reserved
