Surgery and Conservative Management of Camptodactyly in Pediatric Patients: A Systematic Review

Strategy for the Conservative Treatment of Type-III Camptodactyly in Children with Beals-Hecht Syndrome

The authors present a successful case in the conservative treatment of type-III camptodactyly in a patient with Beals-Hecht syndrome. Camptodactyly is a flexion deformity of the proximal interphalangeal (PIP) joint, in the anteroposterior direction, painless and bilateral in 2/3 of the cases. Type-III is the most severe and disabling form, as it usually affects several fingers and is associated with syndromes and other malformations. The case herein reported had the correction achieved with the systematic use of static orthoses started at 7 months of age and completed after 23 and a half months of the intervention.

Congenital Upper-Limb Differences: A 6-Year Literature Review

➤ The Oberg-Manske-Tonkin (OMT) classification of congenital hand and upper-limb anomalies continues to be refined as our understanding of the genetic and embryonic etiology of limb anomalies improves.➤ We have conducted an evaluation of graft and graftless techniques for syndactyly reconstruction; strengths and drawbacks exist for each technique.➤ Treatment for radial longitudinal deficiency remains controversial; however, radialization has shown promise in early follow-up for severe deformities.➤ Recent emphasis on psychosocial aspects of care has demonstrated that children with congenital upper-limb differences demonstrate good peer relationships and marked adaptability.

Eighth case of Li-Campeau syndrome in a Turkish patient caused by a novel pathogenic variant in UBR7 and expanding the phenotype

Li-Campeau syndrome (LICAS) is an autosomal recessive disorder characterized by developmental delay, intellectual disability, genital anomalies, congenital heart defects, and dysmorphic features. LICAS is caused by biallelic pathogenic variants in the UBR7 gene, acting as an E3 ubiquitin-protein ligase. Using exome sequencing (ES), we identified a homozygous novel pathogenic splice site variation c.1185+1G>C in UBR7 in a 32-month-old male from a nonconsanguineous Turkish family with clinical features of LICAS. Sanger sequencing revealed the heterozygous state of parents for this variant and confirmed the co-segregation study. The variant may lead to the loss of function of UBR7 and is in a highly conserved residue. Bioinformatic prediction analysis using in silico algorithms supports the pathogenic effect of the splice site variant in the UBR7.

Treatment of camptodactyly with a new progressive correction device

The aim of this study was to introduce a new progressive correction device and present treatment results in camptodactyly patients. Eight patients (11 fingers) were treated for camptodactyly by an external fixator between February 2019 and April 2020. Mean follow-up was 28.7 ± 3.3 months (range, 24-35 months). Operative times and treatment complications were recorded. Pre- and post-operative flexion contracture, total active range of motion (TAM) and esthetic satisfaction were evaluated at final follow-up. Esthetic satisfaction was rated by the patient on a 1-5 point scale. Seven patients were male, and 1 female. Mean age was 21.6 ± 8.5 years (range, 15-42 years). Mean surgery time was 14.9 ± 2.4 min (range, 10-18 min). Mean preoperative flexion contracture was 85.9 ± 7° (range, 75-95°), and mean postoperative flexion contracture was 4 ± 3° (range, 0-10°). Transient proximal interphalangeal joint swelling was seen in 1 case and pin tract infection in 1. TAM was perfect in 5 fingers and good in 6. Patients were either very satisfied (n = 5) or satisfied (n = 3) with the esthetic appearance of each operated finger. Camptodactyly could be managed with a hinged external fixator simply and effectively with gratifying results in selected patients. LEVEL OF EVIDENCE: Level IV, case series.

Surgical Treatment of Camptodactyly with Malek Cutaneous Approach and Stepwise Release: A Retrospective Multi-centre Study

Background: Clinical manifestations of camptodactyly are varied and no official consensus on the etiopathogenesis or best treatment is available. Conservative treatment is generally preferred and, in refractory patients, surgery might be considered. However, reported results of surgery are often unsatisfactory and it is difficult to compare outcomes as different classification systems are adopted. We reported the outcomes of surgical treatment of camptodactyly with the Malek cutaneous approach and stepwise release, assessed using the Siegert classification. Methods: A retrospective analysis of paediatric patients (≥1 and ≤18 years) with congenital camptodactyly refractory to conservative management (flexion contracture >30°), treated with Malek cutaneous approach and stepwise release surgery between June 2009 and June 2019 with at least 1 year of follow-up was performed. Pre- and post-operative clinical and radiographic assessments were evaluated for degrees of flexion contractures and early (<30 days) or late (>30 days) complications were recorded. Results: A total of 59 patients underwent surgery, of whom 38 (64%), including 42 fingers, were enrolled; mean patient age was 8 years (range 1-18). Post-operative mean flexion contracture was significantly improved (p > 0.001) and no infections were recorded. Mean follow-up was 6 years (range 1-10) and proximal interphalangeal joint extension deficits were rated according to Siegert classification as excellent (69%), good (12%), or fair (9.5%) and poor (9.5%). Conclusions: The Malek cutaneous approach and stepwise release of the retracting soft tissues allow prompt evaluation of the anatomical structures involved in the deformity and seem to be an effective surgical correction in the long term. Level of Evidence: Level IV (Therapeutic).
