UNASSIGNED: Cubitus varus, a common post-traumatic deformity of the elbow in children, poses challenges for both patients and surgeons. Step cut osteotomy has emerged as a reasonable surgical technique to address this condition, offering multiple approaches and modifications.
UNASSIGNED: We present a comprehensive systematic review of techniques for step cut osteotomy in cubitus varus, analyzing 13 studies that meet our inclusion criteria. These studies encompass diverse patient populations, including pediatric and adult cases, and span different geographical regions.
UNASSIGNED: Our systematic review explores three primary osteotomy techniques-Classic Step-Cut Osteotomy, Reverse V Osteotomy, and Modified Step Cut Osteotomy-along with their modifications, providing surgeons with valuable options for individualized correction. Functional outcomes showcase improvements in range of motion, functional scores, and carrying angle, highlighting the technique\'s efficacy in restoring elbow function and enhancing quality of life. Radiological evaluations demonstrate successful corrections of various angles and achievement of bony union, reinforcing the stability and anatomical improvements achieved through step cut osteotomy.
UNASSIGNED: Complication rates are notably low, with transient nerve palsies being the most commonly encountered, often resolving within months. Implant failure and other complications are infrequent, underlining the safety and reliability of step cut osteotomy as a surgical intervention for cubitus varus.While the predominance of retrospective studies and heterogeneity across included studies warrant caution, our systematic review provides a robust and diverse synthesis of evidence. It underscores the significance of step cut osteotomy in managing cubitus varus deformity, emphasizing its versatility, favourable outcomes, and safety profile. Further research with rigorous designs and longer follow-up periods will enhance our understanding of step cut osteotomy\'s role in cubitus varus correction.

After corrective osteotomy of cubitus varus, the lateral condylar prominence is a common problem, which is believed to be due to the unequal relative cuts of the lateral base wedge osteotomy. Therefore, several related solutions have been proposed, such as dome osteotomy and step-cut osteotomies, which solve the above problems to a certain extent. This study aimed to: (I) use a modified corpectomy to correct the deformity, and (II) present a new corpectomy method that uses a 3D-printed specific guide with an isosceles triangle osteotomy. A 12-year-old male presented with a -30-degree cubitus varus deformity 5 years after a supracondylar fracture of the right humerus. The degree of correction was determined from the varus angle and the normal carrying angle on the normal side. A rotating isosceles triangle osteotomy was determined by using Mimics software. The accuracy of the osteotomy angle was confirmed by postoperative radiography. The mean postoperative carrying angle was found to be preserved at the 10-month follow-up, with no complications. A rotating isosceles triangle osteotomy with a 3D-printed patient-specific guide may be providing a relative accurate result. However, in order to obtain more rigorous research conclusions, more cases should be added to examine this methodology for bone deformity surgery in the near future.

Fracture supracondylar humerus is one of the most common fractures encountered in pediatric age group at all levels (both rural and urban). Thus it needs a special review in its management protocol as per the changing trend. Modified Gartland classification is the most accepted classification and has its importance in decision making regarding management and prognosis. Neurovascular complications are mostly associated with Type III A, III B and Type IV variety and they most of the time need surgical intervention for stabilization, exploration of brachial artery, sometimes median nerve exploration and reduction of fracture. Cubitus varus is the most common associated deformity associated with this fracture (especially in Type III A). The aim of the review was to develop an insight for the understanding of variations in presentation and management of supracondylar fracture of the humerus (both simplicity and complexity) and the flowing trend in addition to the recent advances to deal with this particular pediatric orthopaedic entity which often presents as an emergency.
