Clinical Treatment Progress for Large Metacarpal and Phalangeal Bone Defects

Large metacarpal and phalangeal bone defects are a hot topic for orthopedic surgeons due to its high clinical incidence, disability rate, and postsurgical amputation rate, along with its difficult treatment, long treatment course, high cost, and poor effect, all of which have a negative impact on the appearance and function of the patient's hands. There are currently a variety of treatment options for large metacarpal and phalangeal bone defects, each with its own benefits and drawbacks. However, there is no treatment method capable of perfectly resolving all the problems of patients with these defects. In this paper, the authors introduce several common plans for and progress of large metacarpal and phalangeal bone defect treatment.

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.

Staged arthrodesis using the Masquelet technique for osteomyelitis of the finger with articular destruction: a report of two cases

Osteitis of the fingers is a serious infection that needs early diagnosis and appropriate surgical debridement and antibiotic treatment of the infected bone. If the effects of treatments are insufficient, long-term antibiotic treatment and repeated operations could be required. In worst cases, some patients may have to undergo amputation. Recently, the usefulness of the Masquelet technique in extensive traumatic bone defects has been reported. We herein describe two cases of immunocompromised patients with purulent osteitis involving joint destruction of the finger treated by two-stage arthrodesis using the Masquelet technique. They obtained good infection control and better function of the finger than before the operation. Moreover, there was no recurrence of the infection. The Masquelet technique could be an alternative technique for osteitis with high risk of amputation.

The Treatment of Primary Arthritis of the Finger and Thumb Joint

BACKGROUND

Primary finger and thumb joint arthritis is common, with a markedly rising prevalence from age 50 onward. As the population as a whole ages, the need for effective, stage-appropriate treatment of this condition is increasing.

METHODS

This review is based on pertinent publications retrieved by a selective search in the PubMed and Cochrane Library databases.

RESULTS

Pain on movement and morning stiffness are commonly reported symptoms. Thorough physical examination and plain x-rays are mandatory. In the early stages of primary finger and thumb joint arthritis, a conservative, multimodal treatment approach involving the use of splints, physiotherapy, and non-steroidal anti-inflammatory drugs can be helpful. The intraarticular injection of hyaluronic acid or cortisone seems to relieve pain in the short term, but its long-term efficacy in primary finger and thumb joint arthritis is questionable. Arthrodesis (joint fusion) is a reliable surgical treatment option for arthritis of the metacarpophalangeal and interphalangeal joints of the thumb. For mobility-preserving surgery of the metacarpophalangeal joints of the second through fifth fingers, silicone implant arthroplasty remains the gold standard. Symptomatic, advanced arthritis of the distal interphalangeal joint is most effectively treated with arthrodesis.

CONCLUSION

The efficacy of conservative treatment has been documented in high-quality clinical trials, while that of surgical treatment has not. The various surgical methods have yielded benefits in routine clinical use, but these remain to be assessed in randomized and controlled trials.

New reconstruction for bone integration of non-vascularized autogenous bone graft with better bony union and revascularisation

INTRODUCTION

Phalangeal defects are often seen after tumor resection, infections, and in complex open hand fractures. In many cases, reconstruction is difficult and amputation is performed to avoid prolonged rehabilitation that is often associated with a poor outcome. In these cases, the maintenance of length and function presents a reconstructive challenge.

METHODS

We reviewed 11 patients who underwent extensive phalangeal reconstruction with non-vascularized bone graft from the iliac crest using a key-in-slot-joint technique to provide acceptable function and bony union.

RESULTS

In each case, non-vascularized bone graft with a length of 1.4-6.0 cm was used to reconstruct the phalanx. Follow-up ranged from 6 weeks to 5 months, and in all cases, there was bony union after 6 weeks. We evaluated range of motion, function, and as well pain and grip strength of the fingers.

CONCLUSIONS

This case series suggests that a key-in-slot technique allows non-vascularized bone graft to be used in complex large phalangeal bone defects. Due to better bone contact, a sufficient perfusion and revascularisation of the non-vascularized bone graft can be achieved for a quicker and stable bony union. This method appears to be an alternative to amputation in selected cases with a satisfactory soft-tissue envelope.

Spontaneous radioscapholunate fusion after septic arthritis of the wrist: a case report

Bacterial septic arthritis rarely occurs in the upper extremities. Yet, early diagnosis and treatment is important, as a delay in diagnosis results in pain, impaired hand function, and degenerative joint disease. Radioscapholunate (RSL) arthrodesis is a well-established procedure for treating inflammatory arthritis and osteoarthritis (primary or posttraumatic), primarily to achieve pain relief. The wrist deformity correction offers an alternative option to total wrist arthrodesis. Indications for a RSL arthrodesis are osteoarthritis of the radiolunate and radioscaphoid joint with a concomitant intact midcarpal joint. We present a case study of spontaneous RSL fusion post wrist infection caused by a dog bite.
