Donor-Site Morbidity Analysis of Thenar and Hypothenar Flap.

 For the small glabrous skin defect, Thenar and Hypothenar skin are useful donors and they have been used as a free flap. Because of similar skin characteristics, both flaps have same indications. We will conduct comparative study for the donor morbidity of the Free thenar flap and Hypothenar free flap.

The "Swing-Door" Regrafting of Donor Site: An Alternative Method for Split-Thickness Skin Graft in the Hand.

 Skin defects in the hands are common injuries, and autologous skin grafting is the ideal treatment. However, complications can occur at the donor and recipient sites. This study compares the "Swing-door" technique with conventional skin grafting.

Serious Complications of the Percutaneous A1 Pulley Release: Case Reports and Literature Review.

Percutaneous first annular pulley (A1 pulley) release, which has been increasingly used to treat trigger fingers, has been widely established as a safe and simple procedure. Multiple studies have reported positive results of percutaneous A1 pulley release. In this study, however, we report cases of patients who developed complications after undergoing percutaneous A1 pulley release at local clinics.

Hand Reconstruction Using Anterolateral Thigh Free Flap by Terminal Perforator-to-Digital Artery Anastomosis: Retrospective Analysis.

This study aimed to analyze cases of anterolateral thigh (ALT) free flap used for hand reconstruction with terminal perforator-to-digital artery anastomosis. Patients who underwent ALT free flap placement with terminal perforator-to-digital artery anastomosis for hand reconstruction between January 2011 and August 2021 were included. The number, length, and diameter of the perforators and veins, flap size, and operative time were investigated through a retrospective review of charts and photographs.

Single or double Kirschner wire fixation: which provides better outcomes for pediatric proximal phalanx base fractures?

Purpose: The most common hand fracture in children is seen at the base of the proximal phalanx. This study aims to compare clinical outcomes of single versus double Kirschner wire pinning for pediatric proximal phalanx base fractures.

Patients And Methods: The retrospective study enrolled patients who underwent closed K-wire pinning for proximal phalanx base fractures from January 2016 to February 2022.

Fingertip reconstruction with a subcutaneous flap and composite graft composed of nail bed and volar pulp skin.

Background: Fingertip injuries are very common; however, the reconstruction of volar pulp defects with nail bed defects is challenging in the absence of the amputated segment. We reconstructed fingertip amputations with nail bed defects using a new surgical approach: a subcutaneous flap and composite graft.

Methods: We treated 10 fingertip amputation patients without an amputated segment, with exposed distal phalangeal bone and full-thickness nail bed defects between February 2018 and December 2020.

Division of a single free flap in multiple digit reconstruction.

Background: Single free flaps are a commonly used reconstructive method for multiple soft tissue defects in digits. We analyzed the flap size, division timing, and degree of necrosis in cases with various types of flap division.

Methods: We conducted a retrospective review of the medical charts of patients who had undergone single free flap reconstruction for multiple soft tissue defects across their digits from 2011 to 2020.

Reconstruction of Digit Soft Tissue Defects With the Fourth Common Digital Artery Perforator Flap.

Purpose: The hand has unique skin characteristics. Intrinsic flap donors are limited due to functional specificity and compactly connected structures. The hypothenar area is a reliable option for the reconstruction of finger defects.

Partial second toe pulp free flaps in early childhood.

Background: The introduction of the partial second toe pulp free flap has enabled superior aesthetic and functional results for fingertip reconstruction in adults. Children undergoing fingertip amputation for various reasons have limited options for reconstruction. Conventional treatment could shorten the finger, leading to poor cosmesis and function.

Microsurgical Free Tissue Options for Fingertip Reconstruction.

Fingertip injuries occur commonly owing to trauma in everyday life. Performing amputation or stump revision for a fingertip injury can make it possible to quickly return to daily life, but causes functional and cosmetic problems. We believe that free flaps are the ideal way to minimize donor site morbidity and provide satisfactory reconstruction.

Arterial or venous free flaps for volar tissue defects of the proximal interphalangeal joint: A comparison of surgical outcomes.

Background: For volar soft tissue defects of the proximal interphalangeal (PIP) joint, free flaps are technically challenging, but have more esthetic and functional advantages than local or distant flaps. In this study, we compared the long-term surgical outcomes of arterial (hypothenar, thenar, or second toe plantar) and venous free flaps for volar defects of the PIP joint.

Methods: This was a single-center retrospective review of free flap coverage of volar defects between the distal interphalangeal and metacarpophalangeal joint from July 2010 to August 2019.

Long-term outcomes of nail bed reconstruction.

Background: There are various reconstructive options for nail bed defects. However, it is challenging not to leave a deformity. In this study, we investigated differences in outcomes depending on the reconstruction method, attempted to determine which method was better, and analyzed other factors that may affect outcomes.

Flap Coverage of Dysvascular Digits Including Venous Flow-Through Flaps.

A dysvascular digit is defined as a threatened circulatory condition of a digit caused owing to multiple reasons, such as medical illness or trauma. A dysvascular digit always needs surgical manipulation of the vessel in trauma cases. The revascularization of the digit is a priority in such conditions, after which reconstruction of the defect is performed.

Nail bed defect reconstruction using a thenar fascial flap and subsequent nail bed grafting.

Background: Full-thickness nail bed defects with significant exposure of the distal phalanx are typically challenging to reconstruct. We describe a novel method of nail bed defect reconstruction using a thenar fascial flap combined with nail bed grafting.

Methods: Full-thickness nail bed defects were reconstructed in a 2-stage operation involving the placement of a thenar fascial flap and subsequent nail bed grafting.

Volar plate avulsion fracture alone or concomitant with collateral ligament rupture of the proximal interphalangeal joint: A comparison of surgical outcomes.

Background: Volar plate avulsion fracture of the proximal interphalangeal (PIP) joint is one of the most common hand injuries. In this study, we divided patients into two groups: patients with pure volar plate avulsion fracture, and patients with volar plate avulsion fracture concomitant with collateral ligament rupture. The purpose of this study was to compare long-term surgical outcomes between the two groups.

Multiple venous anastomoses decrease the need for intensive postoperative management in tamai zone I replantations.

Background: Venous anastomosis is an important component of digital replantation, but is not always feasible, as some cases require external bleeding to treat venous congestion in the replanted tissue. In the present study, we evaluated the relationship between the number of vein anastomoses and the survival rate of Tamai zone I replantations.

Methods: A retrospective review was performed of all patients who underwent replantation of a fingertip amputation between 2014 and 2016.

The Anconeus Muscle Free Flap: Clinical Application to Lesions on the Hand.

Background: It can be difficult to select an appropriate flap for various defects on the hand. Although defects of the hand usually must be covered with a skin flap, some defects require a flap with rich blood supply and adequate additive soft tissue volume. The authors present their experience with the anconeus muscle free flap in the reconstruction of various defects and the release of scar contractures of the hand.

Analysis of Bone Fixation Methods in Digital Replantation.

Background: Adequate fixation of replanted digits is essential not only for short-term healing but for long-term function. Various bony fixation methods using Kirschner (K-) and intraosseous wire are available in replantation. We examined clinical and radiographic outcomes of fixation methods on bone union after digital replantation.

Fascial Free Flap for Reconstruction of the Dorsolateral Hand and Digits: The Advantage of a Thin Contour.

Background: Fascial free flaps have been widely used for reconstruction of the hand because they are thin. However, studies reporting objective data regarding the advantages of this approach are lacking. Thus, we report our experience with such flaps.

Analysis of 344 Hand Injuries in a Pediatric Population.

Background: The purpose of this study was to identify comprehensive hand injury patterns in different pediatric age groups and to assess their risk factors.

Methods: This retrospective study was conducted among patients younger than 16-year-old who presented to the emergency room of a general hospital located in Gyeonggi-do, Republic of Korea, and were treated for an injury of the finger or hand from January 2010 to December 2014. The authors analyzed the medical records of 344 patients.

Donor-Site Morbidity after Partial Second Toe Pulp Free Flap for Fingertip Reconstruction.

Background: In this study, we characterize the morbidity at the donor-site of partial second toe pulp free flaps in terms of wound management as well as long-term outcomes.

Methods: A single-institutional retrospective review was performed for patients who had undergone partial second toe pulp free flap transfer to the fingertip. Patient charts were reviewed for infection, skin necrosis, wound dehiscence, and hematoma for the donor site.

Short-Term Strength Deficit Following Zone 1 Replantations.

Background: Hand strength deficit following digital replantation is usually attributed to the mechanical deficiency of the replanted digit. Zone 1 replantation, however, should not be associated with any mechanical deficit, as the joint and tendon are intact. We evaluate short-term motor functions in patients who have undergone single-digit zone 1 replantation.

Comparison between Intramedullary Nailing and Percutaneous K-Wire Fixation for Fractures in the Distal Third of the Metacarpal Bone.

Background: To compare clinical and radiographic outcomes between intramedullary nail fixation and percutaneous K-wire fixation for fractures in the distal third portion of the metacarpal bone.

Methods: A single-institutional retrospective review identified 41 consecutive cases of metacarpal fractures between September 2009 and August 2013. Each of the cases met the inclusion criteria for closed, extra-articular fractures of the distal third of the metacarpal bone.
