Objective: The aim of the present study was to evaluate intermediate-term outcomes of Chevron osteotomy for treatment of osteochondral lesions of the talus with mosaicplasty and to assess its effect on surgery and whether it reduces complications that might occur intraoperatively.
Methods: The present study included a total of 42 patients (31 men, 11 women) who underwent Chevron osteotomy of the medial malleolus and who had been followed for more than 2 years. Mean age of the patients was 34 years (range: 18-54 years). Preoperatively, size of the lesions was measured in millimeters in the coronal and sagittal planes using magnetic resonance imaging (MRI). The angle between the osteotomy with the long axis of the tibia was measured on the coronal plane, the angle between the arms and the angle for the screws to be directed to the osteotomy line were measured on the sagittal plane on the postoperative images. Nonunion, malunion, and complications from the screws were evaluated from X-ray images taken at the final follow-up.
Results: Mean duration for follow-up was 31.4 years (range: 24-46). On the X-ray images taken at the final follow-up, no distraction, migration of the distal part, or rotation was observed. Only 1 patient experienced radiological non-union. Mean duration to union was 5.8 weeks (range: 4-14 weeks). Screws of 8 patients were removed at an average of 7.4 months (range: 5-11 months). The angle between the osteotomy line and long axis of the tibia was 29.0°±6.5°, the angel between the osteotomy arms on the sagittal plane was 74.7°±8.3°, and the direction angle of the screws on the coronal plane was 85.7°±5.9°.
Conclusion: Chevron osteotomy is an assistive surgical method used for treatment of osteochondral lesions located in the medial talar joint surface (TOL) which provides fast anatomical healing because it allows efficient fixation due to its geometry.

Purpose: Olecranon osteotomy has been associated with loss of reduction, nonunion, implant failure, and migration of wires. We aim to evaluate quality of reduction of the osteotomy site as a predictor of olecranon osteotomy nonunion.
Methods: One hundred and twenty-five distal humerus fractures that underwent open reduction internal fixation (ORIF) were reviewed.

Background: To investigate the impact of decompressive chevron osteotomy on subchondral bone density at the first metatarsophalangeal (MTP) joint.
Methods: Sixteen feet (12 patients) with hallux rigidus underwent decompressive chevron osteotomy. Standing cone beam 3D computed tomography (3DCT) were assessed preoperatively and at 4-month follow-up, and clinical data were collected.

Hallux valgus (HV) deformity, which is characterized by lateral deviation and pronation of the metatarsophalangeal joint, demonstrates complex 3-dimensional challenges, thus prompting the development of various surgical approaches, including traditional Chevron osteotomy (CO) and novel triplanar Chevron osteotomy (TCO). The objective of this study is to determine TCO at various tilt angles by employing 3D printing for ex vivo osteotomy angle simulations and computer modeling to correct deformities across 3 planes, thus aiming to enhance surgical outcomes by preserving or even increasing the length of the first metatarsal and thereby overcoming the limitations of CO. In this study, we collected and analyzed non-weight-bearing CT data from 55 patients (61 feet) with mild-to-moderate hallux valgus, plantar callosities and metatarsalgia from June 2019 to June 2020.

Background: Minimally invasive surgical (MIS) chevron-type osteotomy for hallux valgus (HV) treatment offers a surgical alternative to open surgery with minimal surgical dissection and a hypothetical decreased risk for soft tissue complications. The objectives of this study were to assess the incidence of injuries to the soft tissue envelope and to the blood supply of the first metatarsal head through gross dissection and, using micro-computed tomography (micro-CT), to identify the safe position to perform the MIS chevron-type osteotomy of the first metatarsal head based on the anatomical data.
Methods: Twenty cadaveric specimens with HV were used for the study.

Background: The authors present a cadaveric validation of a minimally invasive articular cartilage preserving olecranon osteotomy technique for use in the operative management of distal humeral fractures.
Methods: Twenty-four elbows in six male and six female formaldehyde embalmed cadavers were dissected. With the cadaver placed in a lateral decubitus position, a posterior sub-periosteal dissection was performed to the medial and lateral aspects of the olecranon at the level of the joint and Mini Hohmann retractors were inserted into each side of the ulnohumeral joint.
