Fingertip Injury

Finger amputations in children present unique challenges and require special considerations compared to their adult counterparts. Maximizing length and preserving fingertip bulk and sensation is essential for maintaining a functional digit. Synthetic dermal substitutes have been recently used for soft tissue coverage for pediatric syndactyly as well as burn injuries; however, the literature discussing pediatric amputation cases with soft tissue damage proximal to the bony level is limited.In this case, we report a two-year-old patient who developed dry gangrene of her right index finger after multiple rabbit bites and underwent an amputation through the distal interphalangeal joint...

Cervical spinal cord injury (SCI) leads to permanent impairment of arm and hand functions. Here we conducted a prospective, single-arm, multicenter, open-label, non-significant risk trial that evaluated the safety and efficacy of ARCEX Therapy to improve arm and hand functions in people with chronic SCI. ARCEX Therapy involves the delivery of externally applied electrical stimulation over the cervical spinal cord during structured rehabilitation. The primary endpoints were safety and efficacy as measured by whether the majority of participants exhibited significant improvement in both strength and functional performance in response to ARCEX Therapy compared to the end of an equivalent period of rehabilitation alone...

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. METHODS: Twenty-three patients with fingertip defects were treated using the BGcSF technique...

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. METHODS: RHDI has been performed for fingertip amputations with deficit of 1...

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. METHODS: Cadaveric SISAP-flaps were individually dissected, tested for arterial perfusion using red ink and radiopaque dye, and transposed into artificially created same-size defects...

Nail bed reconstruction is crucial after fingertip trauma, impacting both function and aesthetics. In this article, the authors describe a case of partial distal phalanx amputation of the index finger with laceration of the nail bed's remaining part. A traumatically elevated skin-fat flap covered the exposed bone on the fingertip, preserving finger length and sensitivity on the radial side. A full-thickness skin graft from the forearm closed a secondary defect on the finger pulp. Nail bed suturing prevented scarring and nail deformity, and a temporary artificial plastic nail replacement maintained the nail bed's shape...

BACKGROUND: The fingertip amputation is an amputation type of the finger beyond the proximal nail fold. There is no vein available for anastomoses on the dorsal side of the finger, and the palmar vein of the finger is small and tightly attached to the skin. Therefore, it is relatively difficult to implement surgical anastomoses, which poses challenges to the clinical treatment of fingertip amputations. CASE REPORT: A 29-year-old male was admitted to the hospital due to "the amputation of the fingertips of the right index, middle, and ring fingers caused by a heavy object compression 3 h ago"...

The primary aim of this study was to report outcomes after fingertip terminalization in 90 patients over a 19-year period. We report excellent functional outcomes and satisfaction, but a 33% incidence of neuropathic pain.

Human amniotic membrane (hAM) is a collagen-based extracellular matrix that facilitates regenerative wound care. hAM offers several advantageous properties that promote epithelial cell growth, granulation, and angiogenesis. This case report demonstrates how Vivex Cygnus Matrix (Vivex Biologics, Miami, FL, USA) amniotic membrane was used over four weeks to graft a traumatic index finger injury that occurred while fishing. Cygnus Matrix allograft was first placed 72 hours after the accident. Following graft placement, the patient noted an immediate relief in pain and was able to return to all normal daily work activities within 48 hours of graft placement...

This case report is about a patient with self-induced hot water burns several hours after an infraclavicular block with ropivacaine for a scaphoid fracture operation. This patient was honest about what happened. However, some patients are too embarrassed to admit what they did to themselves. The injury may be misdiagnosed by the emergency department physician or by the surgeon because the history is incomplete. The resulting burn, which can lead to fingertip loss when severe, can be erroneously misdiagnosed as an ischemic injury after lidocaine with epinephrine local anesthesia...

Subungual or periungual cutaneous warts are caused by the human papillomavirus (HPV). These lesions can be refractory to destructive therapy, necessitating the use of intralesional immunotherapies such as Candida albicans antigen. In this case report, we present a 23-year-old female who sustained distal fingertip soft tissue necrosis following intralesional injection of Candida albicans antigen for the treatment of a refractory subungual wart. While this patient recovered appropriately with conservative bedside debridement and local wound care, intralesional injections to the digit, or hand are not without sequela...

INTRODUCTION: Traumatic fingertip amputation is the most common type of upper extremity injuries. The V-Y advancement flap is a reliable method for reconstructing fingertip defects, but it is associated with complications such as hook-nail deformity and suture site ischemia. Here, we describe our modifications to V-Y advancement flap technique, termed as "V advancement eversion flap" and review the outcomes of this procedure in 21 patients with fingertip amputation. METHODS: This was a retrospective review of 21 consecutive patients with fingertip injury who were treated surgically using the V advancement eversion flap technique at a single trauma center between 2006 and 2019...

Background: Various studies have examined occlusive dressings in fingertip amputations and reported good outcomes. Occlusive dressing preserves appropriate pH, cell accumulation and moisture for healing, thereby limiting scar formation and deformity. To our knowledge, no study was performed in tropical Asia. This study aims to demonstrate the viability of healing fingertip amputations through secondary intention using an effective dressing technique, even in warm tropical climates. Methods: All patients who presented to our institution with fingertip amputations from 1 July 2020 to 31 July 2022 were analysed retrospectively...

Very often, post-traumatic defects involve multiple tissues. Microsurgical techniques can reconstruct them with tissues taken from a toe: from the nail complex alone to compound osteo-onychocutaneous flaps. Several techniques have been reported since the 1980s. This paper describes techniques and indications for microsurgical nail reconstruction. Technique differs according to the deficit, and first and foremost whether only the nail complex is involved or whether other components of the fingertip important for the normal growth of the nail, such as the phalanx bone or the finger pad, are also missing (toenail flaps and the custom-made osteo-onychocutaneous flaps)...

The fingertip is a complex anatomical structure that is frequently injured, especially in manual workers. Different classifications have been reported, considering injury orientation, level and geometry. To optimize treatment planning, the area of soft-tissue defect should be considered. Treatment aims to conserve as long a finger as possible, restore sensation (S3 + or more) and ensure a pleasant esthetic appearance. When amputation occurs, the best treatment is replantation when conditions allow. When this is not possible, the fingertip should be used as a composite graft or the nail complex can be grafted and soft tissue reconstructed, according to the preferred method...

For people who have experienced a spinal cord injury or an amputation, the recovery of sensation and motor control could be incomplete despite noteworthy advances with invasive neural interfaces. Our objective is to explore the feasibility of a novel biohybrid robotic hand model to investigate aspects of tactile sensation and sensorimotor integration with a pre-clinical research platform. Our new biohybrid model couples an artificial hand with biological neural networks (BNN) cultured in a multichannel microelectrode array (MEA)...

Injuries to the fingertips are the most frequent form of damage to the hand. The nail is an exceptional structure in the human body that offers both stability and protection, as well as the ability to perform fine and precise movements. Nail dystrophies are numerous: post-traumatic, post-infection or degenerative. They raise many difficulties for the hand surgeon. Which anatomical structure is dystrophic? Is there any secondary fungal superinfection to be treated before surgery? Among the various techniques proposed, which one will best improve my patient, as complete cure is rarer than partial failure? Surgical techniques for the most frequent nail dystrophies are described, with their difficulties and drawbacks...
