Reconstruction of the finger pulp with palmar digital artery perforator propeller flap using a digital artery perforator at the lateral base of the finger pulp.

Purpose: The digital artery perforator (DAP) flap is used to repair finger pulp defects as it can help preserve the digital artery. The standard DAP flap donor site is dorsal or lateral; however, the color of the flap typically poorly matches that of the finger pulp. The purpose of this study is to report two types of novel palmar DAP flaps.

Replantation of middle fingertip following complete Tamai Zone 2 amputation and eschar development: A clinical case report.

Introduction: Fingertip injuries are common, and proper management depends on the type of injury and the long-term function. This case report presents a challenging fingertip replantation of the middle finger with single artery anastomosis, which was complicated by an eschar and progressed to healing after six months of post-operative care.

Case Presentation: A 27-year-old man came with a left middle fingertip amputation distal to the distal interphalangeal joint (Tamai zone 2).

Factors predicting composite grafts survivability in patients with fingertip amputations; a systematic review and meta-analysis.

Background: Fingertip amputation is a commonly encountered injury in emergency settings. Composite grafting is a non-microsurgical alternative maintaining digit length with no donor site morbidities. This meta-analysis was conducted to retrieve factors associated with composite graft survivability among patients with fingertip amputations.

"Flap-in-Flap" Technique: Double V-Y Flap in Fingertip Injury Management.

 Fingertip injuries with amputation are one of the common hand injury problems. Several reconstructive options are available for fingertip injury. V-Y advancement flap is one of the common flaps.

New strategy for shortening the consolidation period in distraction lengthening of phalanges or metacarpal bone.

Distraction lengthening of digits enhances hand function in patients with congenital phalangeal defects or traumatic hand amputations. Although callotasis is a useful distraction lengthening method, it is challenging and often results in various complications and prolonged fixation. Based on our experiences, we attempted to develop innovations to reduce the fixation period.

Results of innervated digital artery perforator flap and direct-flow homodigital flap application in fingertip soft tissue amputations.

Objective: The purpose of this study is to compare the results of the innervated digital artery perforator (IDAP) flap and the direct-flow homodigital flap as reconstruction methods for fingertip soft tissue amputations. This issue is important in hand surgery, and we aim to identify the method that provides the best functional and cosmetic outcomes.

Methods: Between 2020 and 2022, 32 patients with fingertip amputations were reconstructed by the same surgeon using two different methods.

Reconstruction of Allen's type IV fingertip amputation via bilateral unequal-sized hallux osteo-onychocutaneous free flaps: A retrospective study with 5-year follow-up.

Purpose: The reconstruction of Allen's type IV fingertip amputation is a clinical challenge. Our team designed bilateral unequal-sized hallux osteo-onychocutaneous free flaps for the long-term reconstruction of Allen's type IV fingertip amputation and conducted a retrospective study with a 5-year follow-up aims to evaluate the effects of this technique.

Methods: A retrospective analysis with a 5-year follow-up including 13 patients with Allen's type IV fingertip amputation who were admitted to our hospital from January 2010 to January 2017 was conducted.

Soft Wearable Body-Powered Hydraulic Actuation System for a Prosthetic Finger Design.

Objective: Finger and fingertip loss is the most common form of upper-limb amputation. With a focus on amputations involving the loss of distal and/or partial middle finger segments, this paper outlines the design and development of a novel soft body-powered hydraulically-driven actuation system for a prosthetic finger, while offering an in-depth examination of its subsystems.

Method: The proposed device utilises a soft wearable hydraulic mechanism to transfer pressure from the proximal interphalangeal (PIP) joint of the human finger to the distal interphalangeal (DIP) joint of the prosthetic finger, enabling movement of the soft prosthetic DIP joint.

Spatial Summation of Localized Pressure for Haptic Sensory Prostheses.

A host of medical conditions, including amputations, diabetes, stroke, and genetic disease, result in loss of touch sensation. Because most types of sensory loss have no pharmacological treatment or rehabilitative therapy, we propose a haptic sensory prosthesis that provides substitutive feedback. The wrist and forearm are compelling locations for feedback due to available skin area and not occluding the hands, but have reduced mechanoreceptor density compared to the fingertips.

Radial Artery Reconstruction After Iatrogenic Cannulation-Related Occlusion: A Case Report.

A 59-year-old male, with a history of angiogram via the left radial artery during the workup for multi-trauma, presented to the hand clinic with a 14-day history of progressive critical ischemia in the left thumb and index finger, along with dry gangrene of the distal index fingertip. Radial artery occlusion was confirmed on imaging. The patient underwent radial artery thrombectomy, arterial reconstruction with vein graft, and amputation of the index fingertip.

Bone grafting combined with a spiral flap technique for the reconstruction of fingertip amputations.

Background: Various reconstructive options exist for distal finger and pulp defects, including grafting and local or distant flaps. In addition to reconstructing the normal anatomical structure, preserving the sensory function of the finger is crucial. This study presents the results of using bone grafting combined with a spiral flap (BGcSF) technique for reconstructing pulp defects accompanied by bone loss.

Comparing clinical and aesthetic outcomes of cross-finger and homodigital reverse digital artery island flap for fingertip injuries: A single-center retrospective cohort study.

Background: Reverse homodigital artery island flap (RHDI) has been reported to have some postoperative complications. Cross-finger reverse digital artery island flap (CRDI), which is harvested from an adjacent intact finger, has been used to decrease these complications. This study aimed to provide a review of the CRDI procedure and compare the clinical outcomes of CRDI with those of RHDI.

Anatomy, evolution, and clinical aspects of the superextended-intercompartmental-supraretinacular artery perforator flap (SISAP-flap): A proof of concept.

Background: Extended soft tissue defects of the fingers-irrespective of their origin-are challenging to treat. In cases of missing amputates or crush injuries, the options are often limited to further amputation, ray resection, or free tissue transplantation. The SISAP-flap was developed to add an extra option to treat finger avulsion injuries or otherwise extended soft tissue finger defects.
