Cubitus varus deformity following paediatric supracondylar humeral fracture remodelling predominantly in the sagittal direction: A three-dimensional analysis of eighty-six cases.

ABSTRACT:

Purpose

Three-dimensional (3D) capacity for remodelling in cubitus varus deformity (CVD) after paediatric supracondylar humeral fractures (PSHFs) remains unelucidated. This study investigated remodelling patterns after PSHFs by examining 3D deformity distribution over time after injury.

Methods

Computed tomography (CT) data of 86 patients with CVD after PSHFs were analysed. The 3D deformity angles in the sagittal, coronal, and axial directions were assessed and correlated with the duration between the age at injury and CT evaluation. For the subgroup analysis, we performed the same correlation analysis in a younger (< 8 years old) and an older group (≥ 8 years old); we categorized the duration into early (< 2 years), middle (≥ 2 to < 5 years), and late periods (≥ 5 years) and compared the deformity angles of each direction among the three groups.

Results

Sagittal deformity showed a moderate correlation with the duration of deformity (r = -0.54; P < 0.001), while coronal and axial deformities showed a negligible correlation. Sagittal deformity showed moderate correlations with the duration in the younger group (r = -0.62; P < 0.001) and weak correlations in the older group (r = -0.37; P = 0.091). In the sagittal direction, the deformity angle in the early period was significantly larger than those in the mid and late periods (P < 0.001). However, there were no significant differences among the three groups in the coronal and axial directions.

Conclusion

Sagittal deformities in CVDs are capable of remodelling, especially in the early period and at a younger age, whereas coronal and axial deformities are less likely to undergo remodelling.

Project description:BackgroundCubitus varus, a common complication of pediatric supracondylar humerus fractures, presents with internal rotation, extension, and varus angulation. While primarily considered a cosmetic concern, it can lead to significant complications, including chronic pain, ulnar nerve palsy, and posterolateral elbow instability. This study evaluates the effectiveness of supracondylar dome osteotomy in decreasing lateral condylar prominence and improving functional outcomes in patients with cubitus varus.MethodsThis retrospective cohort study analyzed 65 patients under 18 who underwent dome-shaped corrective osteotomy between 2017 and 2022 at the Hospital and Rehabilitation Center for Disabled Children, Nepal. Inclusion criteria comprised patients with cubitus varus deformity greater than 10 degrees and at least six months post-trauma. Outcomes were assessed using the Mayo Elbow Performance Score (MEPS), Lateral Condylar Prominence Index (LPI), and radiological measurements of carrying angle (CA).ResultsThe mean age at surgery was 11.77 years (± 3.76), with an average time since injury of 54.15 months (± 31.76). Post-operatively, the radiological carrying angle improved from 23.90° (± 8.84) varus to 5.14° (± 7.64) valgus. The LPI changed from 0.58 (± 16.68) preoperatively to -3.18 (± 16.39) post-operatively. MEPS improved from 89.54 (± 6.66) to 95.23 (± 5.26). Significant improvements in LPI were observed in patients older than 12 years (p = 0.00) and patients with radiological CA less than 20° (p = 0.02) and with a clinical CA less than 20°(p = 0.04).ConclusionsSupracondylar dome osteotomy effectively reduces lateral condylar prominence in cubitus varus, particularly in post-pubertal patients and cases with radiological carrying angles less than 20 degrees. The procedure demonstrates good functional outcomes with acceptable complication rates, making it a viable surgical option for treating cubitus varus deformity.

Project description:BackgroundThe goal of the study was to evaluate the efficacy of physical therapy in restoring function and mobility after a pediatric supracondylar humeral fracture.MethodsThe study included sixty-one patients from five to twelve years of age with a supracondylar humeral fracture that was treated with casting or with closed reduction and pinning followed by casting. Patients were randomized to receive either no further treatment (no-PT group) or six sessions of a standardized hospital-based physical therapy program (PT group). The ASK-p (Activities Scale for Kids-performance version) and self-assessments of activity were used to assess function at one, nine, fifteen, and twenty-seven weeks after injury. Motion was measured at nine and fifteen weeks after injury by a blinded therapist. Anxiety was measured at one and nine weeks after injury with a self-assessment. Differences in ASK-p scores and anxiety level were analyzed with use of multivariate generalized estimating equations.ResultsASK-p scores were significantly better in the no-PT group at nine and fifteen weeks after injury (p = 0.02 and 0.01, respectively) but the difference at twenty-seven weeks was not significant. There were no differences between groups with respect to performance of activities of daily living or time to return to sports. Anxiety at nine weeks was associated with worse ASK-p scores at nine and fifteen weeks in the PT group and with better ASK-p scores in the no-PT group at these time points (p = 0.01 and 0.02, respectively). There were no differences between the groups with respect to elbow motion in the injured arm at any time. Severity of injury had no impact on function or elbow motion in either the PT or the no-PT group.ConclusionsChildren undergoing closed treatment of a supracondylar humeral fracture that was limited to approximately three weeks of cast immobilization received no benefit involving either return of function or elbow motion from a short course of physical therapy.Level of evidenceTherapeutic Level I.
