A retrospective analysis of 12 adolescents undergoing unilateral posterior wedge closing VCR for neglected congenital kyphoscoliosis, assessing surgical outcomes over a mean 2.9-year follow-up.

Design: Single-center case series (Assiut University Hospital, 2015-2020).

Intervention: Modified posterior VCR with unilateral convex wedge resection, spinal shortening, and instrumentation.

Key Steps:

Preoperative CT/MRI for anatomical planning.

Posterior-only approach with pedicle screw instrumentation.

Wedge resection focused on convex side, preserving concave continuity.

Bone grafting (cancellous or mesh cage) post-correction.

Follow-up: Radiographic and clinical assessments up to 2 years post-surgery.

Inclusion Criteria:

Age >10 years.

Congenital kyphoscoliosis diagnosis.

No prior spinal surgery.

Preoperative CT/MRI and 24-month follow-up data.

Exclusion Criteria:

Idiopathic or neuromuscular scoliosis

Previous spinal surgery

Incomplete radiographic or follow-up data

The study population consisted of adolescents (mean age 15.7 years) with neglected congenital kyphoscoliosis, who had not undergone any prior spinal surgery and had complete preoperative and follow-up imaging data. The sample represents a total coverage of all cases meeting criteria during the study period, reflecting the rarity of congenital kyphoscoliosis requiring surgical intervention in adolescence, The patients who have moderate to severe spinal deformity, with a mean preoperative Cobb angle of 53.2° (kyphoscoliosis involves abnormal curvature in both sagittal and coronal planes, hese cases typically present during adolescence, coinciding with the second growth spurt, which is a known period for progression of congenital spinal deformities
