The Masquelet technique for septic arthritis of the small joint in the hands: Case reports

Fingertip Infections

The fingertip is the interface between humans and the world, including the various thorns, dirty needles, and other hazards to be found there. It is unsurprising that this is the site where hand infections most frequently occur. Although commonly encountered by hand surgeons and other physicians, fingertip infections have several mimics, and diagnosis and management is not always straightforward. Early diagnosis and treatment are key to success. As with all infections, they are more common and are more aggressive in immunosuppressed patients. This article reviews fingertip anatomy, common and uncommon fingertip infections and their mimics, and recommendations for management.

Managing Small Joint Septic Arthritis of the Hand

Background: Current guidance for the management of septic arthritis is limited to large joints and, therefore, unspecific to the small joints of the hand, which may present differently, require different diagnostic approaches, and have different complications. The aim of this article was to review current treatment trends for the management of small joint septic arthritis (SJSA) of the hand and offer guidelines for its management. Methods: A systematic review was carried out according to PRISMA guidelines and a survey distributed to Fellows of the British Society for Surgery of the Hand to establish expert opinion. The review and survey were combined to present a set of specific SJSA of the hand infection guidelines. Results: All 20 included studies recommended physical drainage of infected joint fluid; subsequent lavage and early antibiotic therapy, with physiotherapist-guided joint mobilisation. Statistical analysis of the 77 responses to our survey revealed that (in order of preference) the diagnosis was made by history and examination, blood tests, joint aspiration and vital signs; and for interventions: joint elevation and intravenous antibiotics; then joint washout repeated within 48 hours, if necessary. Conclusions: Small joint infection differs from large joint infection because it is difficult to obtain joint aspirate without damaging or opening the joint. We, therefore, recommend utilising exclusion blood tests, imaging and the clinical picture to establish the diagnosis and implement early treatment and rehabilitation. Level of Evidence: Level III.

Septic arthritis of the hand: Current issues of etiology, pathogenesis, diagnosis, treatment

Septic arthritis of the hand is a serious disease that often results in dysfunction of the joint or even the need to perform amputation of the finger. They rank second in the frequency of occurrence after lesions of the knee joint. Many points concerning the etiology, the timing of the development of cartilage destruction and the development of osteomyelitis, approaches to surgical treatment, the duration of antibiotic therapy, and the start of rehabilitation measures remain the subject of numerous discussions. Based on a search in the PubMed, Web of Science and Google Scholar databases down to 1990-2021, publications on septic arthritis of the hand were found and analyzed. The following inclusion criteria were used in our review: (1) Septic arthritis of the hand; (2) Published in a peer review journal; (3) Written in English; and (4) Full text version available. Studies were excluded if they met any of the following criteria: (1) Letters; (2) Articles published in abstract form only; and (3) Cadaveric studies. Septic arthritis of the hand was characterized by the most frequent damage to the joints of the index and middle fingers (> 50% of cases). Up to 90% of cases, the infection enters the joint as a result of penetrating trauma, animal bites, etc. Staphylococcus aureus became the most frequently isolated microorganism (30%-55%), and its polyantibiotic-resistant form Methicillin-resistant Staphylococcus aureus was found, according to various sources, from 0% to 73% among all isolated Staphylococcus aureus. In arthritis, Pasteurella multocida (6%-11%) is often isolated as a result of animal bites. Articular cartilage destruction in the experiment developed within 24-48 h after infection. In clinical studies, the development of osteomyelitis was noted when treatment was delayed by more than 10 d. X-ray data during the first two weeks were uninformative. Priority of surgical treatment of septic arthritis. Drainage and surgical treatment, and with the development of osteomyelitis, the implementation of arthrodesis. Antibacterial therapy for 2-4 wk and early start of rehabilitation measures. Timely surgical treatment in combination with antibiotic therapy and rehabilitation makes it possible to obtain a positive result in the treatment of septic arthritis of the hand.

Masquelet Technique and Arthrodesis for Digit Salvage of the Finger in Traumatic Bone Loss and Osteomyelitis: A Case Report

Use of the Masquelet technique in the hand is uncommon, particularly for cases complicated by osteomyelitis. This case report describes a patient who was advised to proceed with digital amputation following the traumatic segmental bone loss with a non-salvageable distal interphalangeal joint surface complicated by osteomyelitis but refused amputation and requested alternative treatment. We suggested and performed the Masquelet procedure and arthrodesis to salvage the digit. The first stage consisted of surgical debridement and placement of an antibiotic cement spacer, and the second stage included the replacement of the antibiotic cement spacer with an iliac crest autograft and arthrodesis eight weeks after the primary procedure. The Masquelet technique led to the resolution of osteomyelitis, successful osseous union, finger ray salvage, and distal interphalangeal joint arthrodesis.

[Infections of the Proximal and Distal Interphalangeal Joint: 4 weeks of Immobilisation between initial Surgery with Joint Resection and secondary Joint Fusion is sufficient]

BACKGROUND

In 2011 we published our treatment regime for infections of the interphalangeal joints of the hand with infection-related macroscopic cartilage damage. We recommended the resection of the infected joint followed by 6 weeks of immobilisation by external fixation before secondary arthrodesis. In 2013 we reduced the period of immobilisation to 4 weeks within a prospective study.

PURPOSE

This paper analyses the effect of a shortened immobilisation time of 4 instead of 6 weeks between joint resection and secondary joint fusion in bacterial infection of the proximal and distal interphalangeal joint.

PATIENTS AND METHODS

Between March 2013 and July 2014, 20 patients with an infection of an interphalangeal joint of the hand were treated by joint resection and secondary arthrodesis after a reduced time of immobilisation of 4 weeks. The patients were clinically and radiologically evaluated at median of 5,8 (4,7-10,5) months. The results were statistically analysed and compared with the previous study published 2011.

RESULTS

The reduced immobilisation period from 6 to 4 weeks did not result in a significant difference of revisions (p = 0.148). In 18 of 20 patients, the joint infection was reliably cured and the following arthrodesis consolidated. One patient required a revision surgery due to a persistent joint infection, a second patient got a revision surgery after arthrodesis because of a displaced implant. The range of motion of the infected finger was median 147.5 (30-220)°. Achieving a grip strength of 26 (4-64) kg, the affected hand reached 88.5 (47,8-223,1) % of the strength of the opposite side. The subjective functioning of the hand was good (DASH 37.9 (3.3-71.7), Krimmer-Score 2 (1-4)). We did not observe any persistent pain at rest (VAS 0 (0-3)) or under daily activities (VAS 1.3 (0-7)). 50 % of patients stated a sensitivity to cold. Our study of 2011 revealed similar results (ROM of the infected finger 142.5 (30-220)°, grip strength 95 (33-127)%, DASH-Score 23.3 (0-130), Krimmer Score 2 (1-4), VAS at rest 0 (0-7), VAS under stress 4.5 (0-9), sensitivity to cold in 41 % of 27 patients).

CONCLUSION

A decreased immobilisation period from 6 to 4 weeks between joint resection and secondary arthrosis for infections of the interphalangeal joints of the hand do not lead to a negative outcome. The described therapeutical regime results in reliable cure of the bacterial joint infection with a good function of the finger and only minor subjective discomfort.
