A 10-Year Review of Collagenase Versus Fasciectomy in the Treatment of Dupuytren Contracture.

BACKGROUND: Dupuytren disease (DD) is one of the most common disorders of the hand, affecting 5.7% to 11.7% of the global population. This study seeks to evaluate the 10-year efficacy of the 2 most prominent treatment modalities for DD in Veterans Affairs hospitals, injectable collagenase Clostridium histolyticum versus open fasciectomy. METHODS: A retrospective review was conducted of all electronic medical records of patients who underwent open fasciectomy or collagenase injection to treat their persistent Dupuytren contracture between April 2011 and April 2021. All procedures were performed by 1 of 5 senior surgeons at the same Veterans Affairs Hospital. RESULTS: A total of 232 patients were treated for DD, with 247 collagenase injections and 44 open fasciectomies performed in this sample. Collagenase patients were, on average, 6.51 years after intervention at the time of review. Open fasciectomy patients were, on average, 4.56 years after operation at the time of review. Collagenase decreased contractures, on average, by 29.40 degrees, whereas open fasciectomy decreased contractures, on average, by 38.59 degrees. Of the contractures that were initially classified as resolved, 50 of 155 (32.2%) treated with collagenase and 6 of 56 (10.7%) treated with open fasciectomy recurred. The use of open fasciectomy compared with collagenase injections to treat contracture was associated with a 74.2% decrease in the likelihood of recurrence. CONCLUSIONS: This study found that treatment of DD with collagenase injection is associated with a significantly lower degree of deformity correction, lower rate of resolution, and increased rate of recurrence when compared with open fasciectomy.

Pedicled Pronator Quadratus Transposition for Functional Opponensplasty: A Cadaveric Anatomical Study for Feasibility.

BACKGROUND: Techniques on opponensplasty for chronic carpal tunnel syndrome have been described previously. A novel pronator quadratus (PQ) transposition for chronic carpal tunnel syndrome is described. In addition, the relationship of the distal perforating branch of the radial artery to the surrounding tissue is detailed to optimize further use of the PQ flap for clinical applications. METHODS: Ten cadaver hands underwent PQ dissection, and the perforating branch of the radial artery was identified. Measurements were taken from the radiocarpal joint and the radial styloid to the distal perforating branch. Finally, a proposed surgical technique of PQ transposition with proximal radius periosteum to the first metacarpophalangeal joint and anterior interosseous nerve transfer was performed. RESULTS: The average distance of the perforating branch from the radiocarpal joint was 10 ± 1.05 mm, and the average distance from the radial styloid was 17.1 ± 1.6 mm. Pronator quadratus transposed with a layer of radius periosteum demonstrated anatomical feasibility. CONCLUSIONS: The distal perforating branch of the radial artery predictably perfuses the PQ muscle, which may be used in the future as a means of opponensplasty for chronic carpal tunnel syndrome.

Clarification of Extensor Tenotomy for Finger Deformities.

This article clarifies the terminology and different applications of proximal Fowler extensor tenotomy and distal Dolphin extensor tenotomy. Although Fowler is a popular eponym for all finger extensor tenotomies, proximal Fowler tenotomy is specifically indicated for swan neck deformities, whereas distal Dolphin tenotomy is indicated for boutonniere deformities. For swan neck deformities with a distal interphalangeal joint extensor lag of greater than 40°, central slip tenotomy can be combined with terminal tendon imbrication or reinsertion. More distal Dolphin tenotomy of the lateral conjoined bands is complemented by centralization of the lateral bands or central slip reconstruction to correct hyperflexion of the proximal interphalangeal joint. The pertinent anatomic structures, mechanisms of release, and biomechanical principles have been demonstrated using intraoperative and animated videos of the surgical techniques.

The Keloid Area and Severity Index (KASI): an objective tool for the evaluation of keloids.

To aid in the standardization of evaluating patients with multiple keloids, a Keloid Area and Severity Index (KASI) was developed using patient feedback, previous literature, and clinical expertise. The system was validated using intrarater and interrater reliability assessments. Here, we present a verified, reliable method of assessing keloid area and severity in clinical and research settings.

Case series: Amniotic band sequence with craniofacial abnormalities.

BACKGROUND: To objectively describe craniofacial, visual, and neurological features associated with amniotic band syndrome (ABS) and discuss likely associated multifactorial etiology. METHODS: A retrospective review of patients identified with ABS and concomitant limb involvement and craniofacial features was conducted. The following data were collected from the patients' medical records: demographic information, past medical history including birth history, surgical history, previous clinic visits/physical exams, description of craniofacial features and ABS, family history, any noted obstetric complications, visceral features, visual features, craniofacial features, intracranial features, neurological symptoms, developmental features, diagnostic tests (including radiographs, IQ testing, EEG findings, chromosomes), photographs, and treatment history. RESULTS: Seven patients were included in the final cohort, all of whom had a cleft lip with six having both cleft lip and palate. Other craniofacial abnormalities seen were facial clefts which were vertical oblique in nature, tear duct involvement, cranial deformities that required surgical correction with cranial reconstruction, recorded hypertelorism with vision and gaze abnormalities, coloboma, lagopthalmos and optic never dysplasia. CONCLUSIONS: This case series presents seven children with craniofacial involvement associated with amniotic band sequence and attempts to categorize the salient dysmorphology and neurocognitive development. Major craniofacial anomalies in patients with ABS is a rare clinical finding that cannot be completely explained on the basis of premature amniotic layer disruption alone. This study supports that the dysmorphology seen in cases of ABS with craniofacial involvement is complex and most likely multifactorial. LEVEL OF EVIDENCE: IV Case Series.

Prospective Randomized Study of the Effect of Music on the Efficiency of Surgical Closures.

BACKGROUND: Music is commonly played in operating theaters. Some surgeons believe music reduces stress and operative time, while others think music is a distraction and should be avoided. There is limited published evidence evaluating the effects of music on surgical performance. OBJECTIVE: The goal of this study is to evaluate the effect of music on simple wound closure. METHODS: Plastic surgery residents were asked to perform layered closures on pigs' feet with and without their preferred music playing. Simple randomization was used to assign residents to the music playing first or music playing second group. The time to complete the repair was measured and repairs were graded by blinded faculty. Results were analyzed to determine significant differences in time to complete the task and quality of repair. Participants were retested in a second session with music played in the opposite order to evaluate consistency. RESULTS: Listening to preferred music decreased repair time by 8% for all plastic surgery residents (p = 0.009). Subgroup analysis demonstrated even more significant improvement in speed for senior residents (PGY 4-6), resulting in a 10% decrease in repair time (p = 0.006). The quality of repair was also better in the music group, at 3.3 versus 3.1 (p = 0.047). Retesting revealed results remained significant whether music was played first or second. CONCLUSIONS: Playing preferred music made plastic surgery residents faster in completing wound closure with a 10% improvement in senior residents. Music also improved quality of repair as judged by blinded faculty. Our study showed that music improves efficiency of wound closure, which may translate to healthcare cost savings.
