Boutonnière Deformity

Disruption of the central slip is the primary defect leading to boutonnière deformity. In the closed injury early diagnosis of this lesion is rarely achieved due to the limitations of current methods and difficulties encountered in assessing a painful finger. We describe a simple, non-invasive method of diagnosis which can be carried out on all patients and with minimal discomfort. This test is also beneficial in monitoring the progress of conservative management of central slip disruption.

Boutonnière Deformity

We report 20 cases of post-traumatic boutonnière deformity treated by a modification of the direct anatomical repair technique, particularly indicated in late cases which have complete passive motion. A swallow-tailed flap is excised from the fibrous tissue between the two ends of the central slip. The proximal one is then advanced up to the coaptation with the distal edge of the scarred capsular tissue at the insertion on the middle phalanx to which it is sutured in correct tension. Excellent results have been obtained in 72% of cases and good in 5.5%. The 16% of fair results are probably due to the fact that patients didn't use the splint post-operatively and didn't cooperative with physiotherapy.

Invasive Method

Novel non-invasive methods for the diagnosis of malignancies should be effective for early diagnosis, reproducible, inexpensive, and independent from the human factor. Our aim was to establish the applicability of the non-invasive method, based on the analysis of air exhaled by patients who are at different stages of oropharyngeal, larynx and lung cancer. The diagnostic device includes semiconductor sensors capable of measuring the concentrations of gas components in exhaled air, with the high sensitivity of 1 ppm. The neural network uses signals from these sensors to perform classification and identify cancer patients. Prior to the diagnostic procedure of the non-invasive method, we clarified the extent and stage of the tumor according to current international standards and recommendations for the diagnosis of malignancies. The statistical dataset for neural network training and method validation included samples from 121 patients with the most common tumor localizations (lungs, oropharyngeal region and larynx). The largest number of cases (21 patients) were lung cancer, while the number of patients with oropharyngeal or laryngeal cancer varied from 1 to 9, depending on tumor localization (oropharyngeal, tongue, oral cavity, larynx and mucosa of the lower jaw). In the case of lung cancer, the parameters of the diagnostic device are determined as follows: sensitivity—95.24%, specificity—76.19%. For oropharyngeal cancer and laryngeal cancer, these parameters were 67.74% and 87.1%, respectively. This non-invasive method could lead to relevant medicinal findings and provide an opportunity for clinical utility and patient benefit upon early diagnosis of malignancies.

Boutonnière Deformity

Central slip injury is a common occurrence in hand trauma. When the base of the middle phalanx, which is the contact part of the central tendon, is weakened or damaged, extension lag or restriction would be found in the proximal interphalangeal (PIP) joint and the distal interphalangeal joint becomes hyperextended, presenting buttonhole or boutonniere deformation. Buttonhole deformation has limited cases that a hand surgeon can experience, and there is still no clear guideline for treatment, so treatment tends to depend on the knowledge and experience of the treating doctor. In this review, the factors to be considered in determining the treatment of boutonniere deformity are discussed, and nonsurgical or surgical treatment is considered. Treatment of the PIP joint in boutonniere deformity is a difficult task. Understanding the cause of the deformity, the time point and the stage of deformity, the relationship to the biomechanical changes in adjacent joints, the patient’s functional limitations, and the condition of the joint will improve treatment decisions and outcomes. Based on these considerations, an appropriate treatment should be chosen among nonsurgical or surgical treatments. Various surgical options were introduced but none of method guarantee the optimal outcome. Sufficient understanding of deformity and sufficient consultation and cooperation with the patient regarding the treatment process, outcome, and rehabilitation are necessary.
