Principles of reconstruction. Like with like and flap thinning: two essential tools
Full text linkThe "like with like" and the "flap thinning" are two workhorse principles the surgeon must keep in mind to achieve a functional and cosmetic reconstruction of the hand. These principles are underpinned by a thorough knowledge of anatomy and functional hand units, with a wide range of reconstructive procedures that must be finalized to the necessity of the impaired structures. "Like with like" means that a lost tissue must be replaced with another one that can be compared in appearance and function. In addition, good cosmetic is often associated with good function because the complex attempt to get a proper aesthetic always traduces itself into a better functional reconstruction. "Flap thinning" is essential because soft tissue injuries of the hand represent a more difficult reconstructive challenge than similar injuries elsewhere, and the need for thin tissue to wrap the superficial noble structures of the hand is constant. However, the procedure of thinning a flap can be dangerous and must adhere to the vascular architecture of the flap. This paper aims to review and briefly summarize the current literature in this field

Full text linkPurpose: Managing mangled forearms poses a considerable challenge for hand surgeons. The vascularized fibular graft (VFG) is a commonly used technique for addressing this complex issue. This retrospective study aims to assess the outcomes of advanced treatment for complex forearm bone loss necessitating microsurgical treatment with a vascularized fibula flap. Methods: Patients treated with VFG between January 2010 and December 2022 were included in this analysis. Physical and radiographic evaluations were performed for all patients, and they completed patient-reported outcome measures such as the disability of the arm, shoulder, and hand scores, Mayo Wrist scores, and visual analog scale pain (VAS-Pain) scores for both the recipient and donor sites. Patients treated with one-bone forearm (OBF) reconstruction were also assessed using the outcome score of the OBF according to Peterson. Results: A total of 26 cases were treated with VFG for forearm bone defect reconstruction (13 for primary treatment and 13 for secondary treatment of nonunion). Vascularized fibular graft was employed to create a OBF in four cases, a double barrel in three cases, and an osteocutaneous composite flap in nine cases. The average bone defect measured 81 ± 3.4 mm (range: 50–150 mm). Bone healing was achieved at an average of 8.3 ± 5.5 months (range: 4–15 months), with nonunion at one docking point observed in eight cases necessitating revision. At the follow-up end point, patients reported an average disability of the arm, shoulder, and hand score of 13.5%, a Mayo Wrist score of 80%, and a VAS-Pain score of 3/10. The VAS-Pain outcome at the donor site was rated at 4/10. One-bone forearm's mean score was 7/10. Conclusions: Vascularized fibular graft stands as a viable option for mangled forearm reconstruction. Whether through the double barrel technique or as an osteocutaneous composite graft, VFG allows for the simultaneous reconstruction of both forearm bones and associated soft tissue injuries.

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
