Management of partial fingertip amputation in adults: Operative and non operative treatment

Zone I Revision Finger Amputations Performed in the Emergency Department Compared With Those Performed in the Operating Room

Finger amputations are commonly encountered. These may be revised in the emergency department (ED) or the operating room (OR). Previous studies have demonstrated the cost-effectiveness associated with procedures performed in the ED. Patient outcomes have not been described. We retrospectively reviewed patients who presented to our level 1 trauma center with a traumatic partial or complete finger amputation through flexor tendon zone I. All were treated with revision amputation performed in either the ED or the OR between January 2012 and December 2017. A total of 172 patient charts were included. Ninety-three of the revision amputations were performed in the ED, while 79 were performed in the OR. There was no difference in age, race, sex, having a manual labor job, medical comorbidities, or mechanism of injury between the groups. Compared with procedures performed in the ED, procedures performed in the OR had a higher rate of delayed healing, a longer stay in the hospital, and a higher referral to therapy postoperatively. Length of follow-up and number of follow-up visits were not statistically different based on location of procedure. There was no difference in post-procedural infection rate or need for revision procedure between the groups. Our data support the efficacy of performing revision amputation procedures in the ED. Recorded patient complications and subsequent treatment after revision amputations performed in the ED vs the OR were comparable. Those performed in the ED potentially decrease the burden placed on the patient and the health care system. [Orthopedics. 2024;47(3):152-156.].

Reconstruction of multiple fingertip crush injuries with full-thickness skin grafting

Fingertip crush injuries are commonly encountered as a result of workplace accidents causing significant morbidity. The primary goal of reconstruction is to restore function and sensibility, as well as a faster return to work. We reported a patient with multiple fingertip injuries presented 5 days following the initial injury. Copious irrigation and excisional debridement were performed, followed by a full-thickness skin graft harvested from the volar wrist. At the 4-month follow-up, all of the reconstructed fingertips achieved good functionality without any pain or sensory impairment. The length was well preserved and static two-point discrimination was comparable with the contralateral side. Full-thickness skin grafts may provide an excellent alternative reconstruction option in the management of multiple fingertip crush injuries.

IV3000 semi-occlusive dressing use in simple and complex fingertip injuries: efficacy and affordability

Objective:

This study aimed to explore the efficacy of the IV3000 semi-occlusive, transparent adhesive film dressing in the non-surgical management of simple as well as more complex fingertip injuries.

Method:

In this qualitative study, patients with fingertip injuries were prospectively recruited and treated conservatively with the dressing between 2015 and 2017. Inclusion criteria included any fingertip injury with tissue loss and patient consent for non-surgical treatment consistent with the study protocol. Exclusion criteria included injuries needing surgical intervention for tendon injury or exposure, joint dislocations, distal phalangeal fractures requiring fixation, bone exposure, isolated nail bed lacerations and any patients eligible for surgical repair who did not wish to be managed conservatively.

Results:

A total of 64 patients took part in the study. The patients treated with the dressing were asked to rate functional outcome, of whom 40 (62.5%) patients reported the outcome as ‘excellent’, 19 (29.7%) as ‘satisfactory’, five (7.8%) as ‘indifferent’ and none (0%) as ‘unsatisfactory’. A reduced pulp volume at completion of healing was felt by 21 (32.8%) patients, but all patients were ‘satisfied’ with the aesthetic appearance of their fingertips at final clinical review. Average healing time was 4.5 weeks across the group, with the average time for return to work being just under one week. We estimate a 60% reduction in cost with the conservative versus the surgical management option.

Conclusion:

This study showed that, for participants, the IV3000 dressing was an affordable and effective option for the conservative treatment of simple fingertip injuries and in the management of more complex fingertip injuries.

Management of Fingertip Injuries: A Survey of Opinions of Surgeons Worldwide

Introduction  Fingertip injuries are common injuries in all ages. There is currently no consensus nor evidence to support the use of any one treatment, with numerous options available for management. The aim is to review the consensus for treatment of fingertip injuries among surgeons worldwide.

Materials and Methods  Nonprobability judgment sampling using purposive method was performed on surgeons ( n = 65) using two digital platforms of the community of practice of hand surgeons. Three illustrative case scenarios were presented to the participants to understand their consensus on treating fingertip injuries, and their choice of treatment for themselves with a similar injury.

Results  This survey demonstrates that there is a wide range of treatment preferences for fingertip injuries for each clinical scenario. In Allen 1 and in crush injuries, most respondents favored healing by secondary intention (66.2 and 92.3%, respectively). In Allen 3 injuries, 72.3% favored surgical intervention. In all clinical scenarios, most surgeons would want their own fingertip injuries treated identically to how they would treat patients with similar fingertip injuries (93.9, 96.9, and 95.4%, respectively). Furthermore, our study demonstrated experience in surgery was not associated with treatment preferences.

Conclusion  Management of fingertip injuries remains controversial, but this study is suggestive that treatment preferences may not be determinant on patient factors, given that all of our respondents are highly functioning individuals who practice microsurgery, but most chose to administer the same treatment to patients as they would to themselves.

Concurrent musculoskeletal complaints in elbows, shoulders, and necks after common hand and forearm injuries or conditions: A cross-sectional study among 600 patients

STUDY DESIGN

This is a cross-sectional study among 600 patients.

INTRODUCTION

Isolated hand and forearm injuries or conditions are common in the emergency and orthopedic departments. So far, little is known about whether these patients suffer from concurrent musculoskeletal complaints (MSCs) besides their hand and forearm complaints. Neglecting concurrent MSCs in the upper limbs and necks could hamper rehabilitation and prolong the time taken to return to daily and work-related activities.

PURPOSE OF THE STUDY

The purpose of this study was to investigate the prevalence of concurrent MSCs in the elbow, shoulder, and neck after common hand and/or forearm injuries or conditions.

METHODS

This study included 600 patients with any type of diagnosis referred to rehabilitation after hand and/or forearm injuries or conditions. Basic characteristics, diagnoses, and location of patients' symptoms were collected and analyzed.

RESULTS

The overall prevalence of concurrent MSCs was 40%. Twenty-eight percent of the whole sample developed concurrent MSCs after the hand and forearm injury or condition. The gender distribution was 68% women and 32% men. The most common location for complaints was the shoulder (62%), followed by the elbow (49%), and the neck (32%).

DISCUSSION

The present results suggest that MSCs from the elbows, shoulders, or necks are very common in patients with hand and/or forearm injuries or conditions.

CONCLUSION

Clinicians treating patients with isolated hand and forearm injuries or conditions should be aware of the high prevalence of concurrent MSCs. Future research should investigate if specific rehabilitation, focusing on concurrent MSCs, may influence the outcome in this population.

Expanding indication of free hypothenar flap transfer: Sequential pedicled ulnar palm flap transfer to a relatively large hypothenar flap donor site

BACKGROUND

Free hypothenar flap (HTF) transfer allows sensible soft tissue reconstruction of the fingertip. However, HTF is basically indicated for a relatively small soft tissue defect, as width of an HTF is limited up to approximately 20 mm to allow primary donor site closure. Combined with sequential local flap to an HTF donor site, a larger HTF can be used without the contracture risk. The aim of this study was to evaluate feasibility of free HTF transfer and sequential ulnar palm flap (UPF) transfer (HTF-UPF) for relatively large fingertip reconstructions.

METHODS

Medical charts of patients who underwent HTF-UPF for fingertip reconstruction were reviewed. An HTF was designed transversely proximal to the proximal palmar crease, and a slightly smaller hemi-spindle-shaped UPF was designed longitudinally on the mid-lateral aspect of the ulnar palm; the UPF was used to close the HTF donor site. Patient and flap characteristics, intra-operative findings, and postoperative results were evaluated.

RESULTS

Twelve patients with average age of 42.7 years were included. HTF-UPF procedure was performed on 12 fingers. HTF's length/width ranged from 45/20 to 70/40 mm (average, 52.5/32.1 mm). UPF's length/width ranged from 40/20 to 55/30 mm (average, 46.7/24.2 mm). Time for sequential UPF transfer ranged from 3 to 9 min (average, 5.1 min). All HTFs and UPFs survived without flap necrosis or scar contracture. Postoperative sensation was comparable with the contralateral fingertip.

CONCLUSIONS

HTF-UPF procedure allows relatively large fingertip reconstruction with a minimum risk of HTF donor site contracture.

Nail Regeneration of an Allen III Fingertip Amputation After a Dog Bite Using the Semi-occlusive Dressing Technique: A Case Report and Literature Review

There is ongoing controversy regarding the best treatment of fingertip amputations, conservative treatment with secondary healing or surgical intervention. Healing by secondary intention has been proven to offer satisfactory recovery and function. More extensive wounds are treated surgically. However, even in Allen III and IV amputations, there is a lack of evidence to support enhanced healing and function of fingertips after surgical treatment compared to conservative management. Regarding fingertip amputations after animal bites, thorough debridement is the preferred treatment due to various micro-organisms, while there is no consensus about the primary closure of the wound.

Inclusion cri­teria are complete amputations even with bone involvement at all levels. Exclusion criteria are skeletonized distal phalangeal bone, not surrounded by soft tissues, joint involvement and exposed tendon. It offers complete regeneration of the fingertip without signs of infection, even in animal bites wounds. There are few reports in the literature regarding the semi-occlusive dressing for treating fingertip amputations-only one report uses this technique after an animal bite in a two-year-old girl.

In this case report, an Allen III fingertip amputation caused by a dog bite in a 64-year-old female was managed successfully using the semi-occlusive dressing technique. At the final follow up three months after the injury, the aesthetic results were satisfactory. The fingertip with the nail complex was almost normal with no nail hook deformity. The pad skin regenerated with no signs of infection. The functional results were excellent, with no joint stiffness or disability. The sensibility was satisfactory with two-point discrimination of 4 mm, and there was no tenderness, cold intolerance, or neuroma. The patient was satisfied and able to participate in all daily activities. 

The semi-occlusive dressing technique is an alternative treatment option for Allen III fingertip amputations after animal bites. It promotes regenerative healing, and despite bacterial colonization, no infection has been reported.

Fingertip Amputation Injury of Allen Type III Managed Conservatively with Moist Wound Dressings

BACKGROUND Fingertip amputation injury is treated surgically or conservatively. Management strategies for these injuries vary depending on not only the site and the degree of tissue loss in the wound but also the country and region. Conservative management or revision amputation is common in the United States. On the other hand, operative management such as replantation or reconstruction is preferred in Japan; accordingly, a surgery is performed even in cases eligible for conservative management. Here, we report a case of fingertip amputation injury for which reconstructive surgery was recommended by a plastic surgeon, but the patient opted for conservative treatment, which was performed using moist wound dressings. CASE REPORT A 36-year-old woman suffered an Allen type III fingertip amputation injury with her right middle finger crushed in a thick iron door. The amputated fingertip was not retrieved. The plastic surgeon in charge initially recommended reconstructive surgery to the patient. However, the patient opted for conservative management; therefore, she visited the Wound Care Department in our hospital. Conservative treatment using moist wound dressings (Plus moist™) was performed, and the wound healed after 12 weeks, with outstanding aesthetic and functional results. CONCLUSIONS Conservative management with moist wound dressings can be a successful treatment modality for Allen type III fingertip amputation injury. In cases where the fingertip amputation injury can be treated using either surgery or conservative treatment, it is better to prioritize the patient's wishes when selecting the treatment option.

Primary Management of Nail Bed and Fingertip Injuries in the Emergency Department

Appropriate management of the acute fingertip and nail bed injury is critical for optimizing patient outcomes. Mismanaged injuries can lead to chronic pain and deformity. Subungual hematomas may be treated with simple trephination for pain relief. Nail bed lacerations may be repaired using dissolvable suture or octyl-2-cyanoacrylate, and in most cases with no need to replace the nail plate or stent the fold. Amputations, partial or complete, can be treated with a wide variety of techniques, but many distal injuries can be left to heal by secondary intention with excellent results.

Potential of Tissue-Engineered and Artificial Dermis Grafts for Fingertip Reconstruction

BACKGROUND

Management of skin and soft-tissue defects of the fingertips is functionally and aesthetically important, but controversial, especially when bones are exposed. Recent advances in wound healing technology allow the use of cells or biological dermis. The authors studied the clinical efficacy of tissue-engineered dermis grafts and artificial dermis grafts versus immediate reconstructive procedures, such as the reverse digital artery island flap, in treating bone-exposed fingertip defects.

METHODS

One hundred eighty-two patients with bone-exposed fingertip defects treated with tissue-engineered dermis grafts (n = 71), artificial dermis grafts (n = 23), or reverse digital artery island flaps (n = 88) were included in this retrospective cohort study. Surgical time, duration of hospitalization, total cost, success rate, healing time, sensory recovery, range of motion, scar quality, and patient satisfaction were compared.

RESULTS

No tissue-engineered or artificial dermis graft exhibited graft rejection or failure, whereas there was one partial loss and one total loss after reverse digital artery island flap surgery. Tissue-engineered dermis grafts were superior in scar quality, and artificial dermis grafts had shorter surgical times and lower surgical costs; both groups demonstrated superior results in postoperative range of motion and sensory recovery in two-point discrimination tests and shorter hospitalization, compared with the reverse digital artery island flap group. The reverse digital artery island flap had shorter complete closure time and less postoperative tingling sensation. There were no differences in overall patient satisfaction among the groups.

CONCLUSIONS

Tissue-engineered and artificial dermis grafts may be promising alternatives for fingertip reconstruction. In particular, tissue-engineered dermis grafts may deliver superior functional results, including recovery of sensory discomfort and aesthetic results in terms of scar quality over artificial dermis grafts.

Self-inflicted finger cold injury leading to amputation: Report of a case

A cold injury can result in devastating outcomes, leading to significant morbidity and loss of distal extremities. Amputations are common after severe frostbite injuries with delayed presentation, often mediated by post-injury arterial thrombosis. Ischemic injuries are managed according to the ischemia time. The most controversial aspect of treating a salvage injury is the time of surgical intervention, which used to be based on the previous management dogma freeze in January, amputate in July. Recently, the paradigm has shifted to early surgical management if the level of viability of the deep structure can be ascertained using 99mTc pertechnetate scintigraphy (99mTc bone scans). We present a case of a finger amputation resulting from a cold injury secondary to a crush injury.

Fingertip Injuries and Amputations: A Review of the Literature

The fingertip is defined as the part of the digit distal to the insertion of the extensor and flexor tendons on the distal phalanx. Devastating injuries to the hand occur every year that lead fingertip amputations in thousands of people. The highest incidence rates are usually seen in children less than five years old and in adults over the age of 65. There are various presentations of injury that may end up with post-traumatic fingertip amputation, including lacerations, avulsions, and crush injuries. The fingertip is vital for sensation, as it has a high concentration of sensory receptors, and hence the restoration of sensation is the most important focus of treatment. The three main goals of treatment are the restoration of sensation and durability in the tip and assuring proper bone support to allow for nail growth. Many complications can arise after fingertip amputation, including delayed wound healing, nail deformities with poor aesthetics, hypersensitivity, residual pain, cold intolerance, scar retraction, flexion contractures, chronic ulceration, infection, and flap loss. The objective of this study is to provide an overview of the anatomy of the fingertip, the presentation of fingertip injuries and their management, and complications that might arise after surgery.

Survival rates and risk factors for failure using an interposition vein graft for fingertip amputations with segmental vessel defects

PURPOSE

This study aimed to compare survival rates and risk factors of replantation failures using an interposition vein graft in fingertip amputations with segmental vessel defects with those using simple end-to-end anastomosis in amputations.

PATIENTS AND METHODS

Between 2004 and 2015, 776 (647 males and 129 females) with single Zone I or II amputations of digits underwent replantation. Among these, simple end-to-end anastomosis was performed in 698 replantations, while interposition vein grafts were used for either arterial or venous repair or both in 78 amputated fingertips. The survival rate was compared between the groups. Logistic regression analysis was performed to identify risk factors predicting replantation failure in all study subjects.

RESULTS

Among 776 replantations, 713 (91.9%) survived. At latest follow-up, of 698 cases in the simple anastomosis group, 650 (93.1%) survived; of 78 cases in the vein graft group, 63 (80.8%) survived (p > .001). Logistic regression analysis revealed that avulsion type (odds ratio [OR] 3.121; 95% confidence interval [CI], 1.211-8.064; p = .018) and zone II amputation (OR, 2.370; 95% CI, 1.382-4.065; p = .002) were significant risk factors for replantation failure.

CONCLUSION

This study demonstrates that the survival rate (80.8%) of the vein graft in fingertip amputation with segmental vessel defects was shown to be a possible option to increase the survival rates in case with segmental vessel defects where simple anastomosis could not be performed. However, avulsion type and zone II amputation are important risk factors of replantation failures.

Cross-finger subdermal pocketplasty as a salvage procedure for thumb tip replantation without vascular anastomosis: a case report

Objectives Fingertip amputation is often encountered in emergency departments, especially in hospitals located near industrial areas. Replantation of the fingertip can be considered when the normal architecture is preserved in cases of sharp amputation. The goal of replantation is to preserve cosmesis and function, especially for the thumb because of its involvement in grasping and the key pinch. Even when microsurgical vascular anastomosis is applied, the absence of venous anastomosis along with the high rate of failure of arterial anastomosis in zone 1A fingertip amputation may lead to replantation failure. Methods We herein present a case report of thumb tip amputation salvaged via a modified cross-finger technique. The recipient site was on the ipsilateral radial side of the intermediate phalanx of the middle finger. Results The thumb tip was successfully replanted with no vascular anastomosis, and this new technique prevented stiffness in the metacarpophalangeal and interphalangeal joints of the thumb and middle finger. Conclusions This procedure can be performed in local clinics and emergency departments without the need for arterial and venous anastomoses.
