Overview

Early identification and treatment of hand infections are essential to achieve optimal outcomes [1]. Delayed diagnosis can result in amputation or death [1]. Hand infections are associated with a high rate of complications that are often difficult to manage [2]. Prompt diagnosis, surgical debridement, and antibiotic coverage remain the standard of care [12].

Management principles for hand osteomyelitis include good surgical debridement and culture-guided antimicrobial therapy [3]. Antibiotic therapy typically lasts 4–6 weeks, though the optimal length and mode of administration remain under study [3]. Initial treatment of mycobacterial infections involves a combination of long-term antibiotics and surgical debridement, with reconstructive procedures aiding in restoring lost function [6]. Deep infection after hand surgery is uncommon but can lead to significant morbidity [7].

Challenges persist in managing hand infections in immunosuppressed patients and intravenous drug users [12]. Aggressive treatment is needed in immunosuppressed patients to prevent limb- and life-threatening complications from bone and soft-tissue infections [18]. The choice of empiric antibiotics for acute hand infections should be based on the severity of the infection, the comorbidities of the patient, and local prevalence of MRSA [13]. The incidence of virulent and MRSA infections is rising [18].

An initial debridement of dorsal hand infections at the bedside is at least as effective as formal debridement in the operating room [29]. Bedside debridement decreases the number of formal debridements and hospital days without increasing complications [29].

Anatomy & Pathophysiology

Prompt diagnosis and early treatment of hand infections are necessary to prevent complications such as hand stiffness, contractures, and amputation [17]. Hand and upper-extremity infections are usually a clinical diagnosis, but imaging and laboratory evaluation aid in diagnosis [4]. An excellent knowledge of hand anatomy and function allows for an accurate diagnosis and effective management of deep space infections [14].

Pyogenic Flexor Tenosynovitis: Early diagnosis and prompt treatment are required to preserve the digit and prevent morbidity and loss of hand function [22]. Despite timely and thorough treatment, severe pyogenic flexor tenosynovitis can lead to impaired function or amputation of the affected digit [31].

Pediatric Considerations: Pediatric hand infections involve unique environments and characteristics, including the frequency of fingers in mouths, open growth plates, and typically more robust circulation with fewer systemic comorbidities [25]. Chronic recurrent multifocal osteomyelitis of the hand is a rare pediatric condition that presents special functional and anatomical considerations [49].

Iatrogenic and Traumatic Etiologies: Complications of the fingers and hand after arthroscopic rotator cuff repair, such as carpal tunnel syndrome, flexor tenosynovitis, and complex regional pain syndrome, easily occurred in patients with a past history of carpal tunnel syndrome or tenosynovitis and in patients with edema [51]. Animal bite injuries of the hands should be treated immediately to avoid further complications [48].

Classification

Hand infections encompass a diverse array of entities with potential for serious morbidity [11]. Atypical hand infections are difficult to recognize and treat due to their indolent nature and nonspecific symptoms [5]. Chronic hand infections are uncommon and require a high index of suspicion for early diagnosis [9]. These chronic infections are grouped by microorganism into bacterial (mycobacterial and others), fungal, and viral types [9]. Fungal infections of the hand are most commonly cutaneous infections involving the skin and nails [23]. Renal disease and diabetes increase the risk of failed outpatient management of cellulitic hand infections [20].

Open Fracture Classification: The new classification system for open fractures of the hand divides patients into three groups based on a risk score to predict infection requiring re-debridement [34].

Necrotizing Soft Tissue Infection (NSTI) Classification: NSTIs can be classified based on anatomic location, depth of involvement, or microbial pathogen [37]. * Type II: Monomicrobial and comprise approximately 20% to 30% of cases [37]. These infections are caused by group A beta-hemolytic streptococci (GAS) either alone or in association with Staphylococcus aureus [37]. * Type IV: Fungal, rare, and primarily affect immunocompromised patients [37].

Clinical Presentation

Hand infections are primarily a clinical diagnosis [4]. Imaging and laboratory evaluations serve to aid in the diagnostic process [4]. Atypical hand infections present with an indolent nature and nonspecific symptoms, making them difficult to recognize [5]. Specific presentations and treatments are emphasized for each type of chronic hand infection [9]. Fingertip infections can mimic common infections, requiring awareness of obscure conditions and relevant anatomy [24].

Pediatric hand infections occur in a unique environment characterized by the frequency of fingers in mouths, open growth plates, and typically more robust circulation with fewer systemic comorbidities [25].

The diagnosis of infectious flexor tenosynovitis has historically been made based on physical exam using Kanavel's signs [26]. The specificity of Kanavel's signs for diagnosing infectious flexor tenosynovitis has come into question [26]. A higher number of Kanavel signs were present in patients with confirmed flexor tenosynovitis compared to those with finger cellulitis without concomitant flexor tenosynovitis (2.9 vs. 0.5) [26].

Radiographic soft tissue swelling does not distinguish flexor tenosynovitis from other causes [26]. Magnetic resonance imaging has been described in aiding the diagnosis of flexor tenosynovitis, but its sensitivity and specificity have not been well studied [26]. Ultrasound has been briefly studied as a diagnostic tool for flexor tenosynovitis with high sensitivity but mediocre specificity [26]. Ultrasound assessment of flexor tenosynovitis comes with inherent user variability and limitations with access and equipment [26].

Diagnosis of septic arthritis of the wrist is made based mainly on a thorough patient history, physical examination, and joint aspiration [27]. No serum laboratory values have been shown to consistently confirm wrist joint infection [27].

Investigations

Early identification and treatment of hand infections are essential to achieve optimal outcomes, as delayed diagnosis can result in amputation or death [1]. Early identification of atypical hand infections through appropriate laboratory testing is imperative for eradication of the causative organism [5]. A high index of suspicion coupled with an excellent knowledge of hand anatomy and function allows for an accurate diagnosis and effective management of deep space infections [14].

Laboratory: Clinicians should be aware of obscure conditions that can mimic common fingertip infections [24]. The incidence of finger infections presenting to emergency departments is rising [19]. Patients aged 40 to 59 years are most at risk for finger infections presenting to emergency departments [19]. Diagnosis of upper-extremity nontuberculous mycobacterial infections is often delayed because of indolent presentation and lack of clinical suspicion [44].

MRI: Magnetic resonance imaging (MRI) has been described in aiding the diagnosis of flexor tenosynovitis, but its sensitivity and specificity have not been well studied [26]. MRI access and time spent obtaining MRI may delay diagnosis, with a negative impact on patient outcomes [26].

CT: Contrast-enhanced computed tomography (CT) has been evaluated to increase the successful diagnosis of acute pyogenic flexor tenosynovitis [26].

Ultrasound: Ultrasound diagnosis of flexor tenosynovitis comes with inherent user variability and limitations with access and equipment [26].

Other Considerations: The specificity of Kanavel's signs for the diagnosis of infectious flexor tenosynovitis has come into question [26].

Treatment

Non-Operative

The use of prophylactic antibiotics in small elective soft tissue procedures of the hand is debated and often not necessary [7]. There is no significant difference in infection rate in elective hand surgery whether antibiotics were administered preoperatively or not [28]. Outpatient management of diabetic hand infections provides a safe alternative to inpatient admission in selected patients [33].

Operative

Indications: Early identification through appropriate laboratory testing is imperative for the eradication of the causative organism in atypical hand infections [5]. Surgical treatment paired with medical management is imperative for the eradication of the causative organism in atypical hand infections [5]. Initial treatment for mycobacterial infections in the hand and wrist involves a combination of long-term antibiotics and surgical debridement to cure the infection [6]. Management of osteomyelitis of the hand and wrist should consist of a combined surgical and medical approach to achieve the most favorable outcome [30].

Surgical Approach / Technique: Prompt diagnosis and early treatment with broad-spectrum intravenous antibiotics and surgical irrigation and debridement are essential to avoid complications and preserve hand function in pyogenic flexor tenosynovitis [16]. Severe pyogenic flexor tenosynovitis can still lead to impaired function or amputation despite prompt treatment [16]. The rising incidence of virulent and MRSA infections emphasizes the need for aggressive treatment in immunosuppressed patients to prevent limb and life-threatening complications [18].

Empiric Antibiotic Selection: The choice of empiric antibiotics for acute infections of the hand should be based on the severity of the infection [13]. The choice of empiric antibiotics for acute infections of the hand should be based on the comorbidities of the patient [13]. The choice of empiric antibiotics for acute infections of the hand should be based on local prevalence of MRSA [13].

Complications

The complications associated with mycobacterial hand infections can be significant [10]. There is a rising incidence of virulent and MRSA infections in hand surgery [18]. Since 1961, the rates of both community-acquired MRSA and health care–associated MRSA hand infections have increased rapidly [38]. The incidence of finger infections presenting to emergency departments is rising, with 40- to 59-year-old patients most at risk [19].

Infection: HIV infection increases the risk of developing a hand infection but does not lead to an increased risk of revision surgery or ablation [35]. Immunosuppressed patients require aggressive treatment to prevent limb and life-threatening complications [18].

Other Considerations: The demographic shift toward 40- to 59-year-old patients represents a key risk profile for emergency department presentations of finger infections [19].

Recovery

Light activity (weeks): Specific week ranges for light activity are not provided in the current evidence base.

Full activity (months): Specific month ranges for full activity are not provided in the current evidence base.

Complete recovery / outcome plateau (months): Specific month ranges for complete recovery are not provided in the current evidence base.

Rehabilitation protocol: Management of hand osteomyelitis requires good surgical debridement and culture-guided antimicrobial therapy [3]. For atypical hand infections, early identification through appropriate laboratory testing and surgical treatment paired with medical management is imperative for eradication of the causative organism [5]. Initial treatment of mycobacterial infections in the hand and wrist involves a combination of long-term antibiotics and surgical debridement to cure the infection [6]. Prophylactic antibiotics are indicated for hand procedures lasting longer than 2 hours, contaminated wounds, and open fractures [7].

Functional milestones: Severe pyogenic flexor tenosynovitis can lead to impaired function or amputation despite timely and thorough treatment [16, 31]. Complications associated with mycobacterial hand infections can be significant [10].

Other Considerations: The incidence of finger infections presenting to emergency departments in the United States was rising from 2012 to 2016, with patients aged 40 to 59 years being most at risk [19]. Factors including time to antibiotics, time to operative debridement, smoking status, and chronic disease comorbidities were not predictive of infection or nonunion in open hand fractures [45]. Early amputation to maximize disease-free survival may be appropriate for patients with hand osteomyelitis and arterial calcification [47]. Regarding pin site care in adult hand and wrist surgery, a protocol from Ilizarov confirms a very high wire survival rate (99.5%) and a very low rate of pin site infection (4.5%) [15]. There were no cases of bony infection requiring further surgery in the study supporting this protocol [15]. The study supports the recommendation to leave wires exposed in adult hand and wrist surgery when the specific Ilizarov protocol is adopted [15].

By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.

j. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

k. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

a. retain the following if it is supplied by the Licensor with the Licensed Material:

i. identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of warranties;

v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;

b. indicate if You modified the Licensed Material and retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
