“…For this study, we used DP, lateral, and oblique radiographic projections under load to obtain the following angulations: first intermetatarsal angle (IMA), hallux abductus angle and position of the sesamoids, assessing the degree of the tibial sesamoid and the angle of sesamoid rotation [ 40 - 42 ]. The results showed a positive correlation between deformity in the transverse hallux plane and in the frontal plane, where the sesamoids are affected together with the angle of inclination of the first radius [ 40 , 41 ]. Other authors, such as Scranton [ 32 ] and Mortier [ 33 ], used axial imaging of the sesamoids to quantify pronation.…”

“…It will be considered reduced if the medial sesamoid is in the midline of the crest of the first radius, and not reduced if it is in any other position [ 42 ]. As for the lateral aspect, the head of the first metatarsal in loading assumes a pronated position, bringing the phalanx into the valgus and increasing its deformity [ 41 , 42 ].…”

Patient: Female, 28-year-old Final Diagnosis: Congenital heart disease • Down’s syndrome • flat foot • hallux valgus Symptoms: Foot pain • knee joint pain • low back and hip pain, gait changes, proximal muscle weakness Clinical Procedure: — Specialty: Podiatry • Surgery Objective: Congenital defects/diseases Background: Tarsometatarsal joint (TMJ) arthrodesis is common method used for correcting hallux abductus valgus (HAV). Its popularity has grown due to studies revealing HAV’s triplanar deformity with frontal plane rotation. This case report presents a 28-year-old woman with Down syndrome, congenital heart disease, and a history of knee surgery and plantar fasciitis, with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. Case Report: Examination revealed severe foot deformities, and radiographic studies confirmed the condition. A surgical intervention was planned, and the patient’s cardiologist confirmed she was fit for the procedure. The modified Lapidus technique with frontal plane rotational correction included realigning the metatarsal joint, resecting spurs, osteosynthesis material, and arthrosis in the sinus tarsi. After surgery, the patient underwent a recovery period without support for 8 weeks and received appropriate medical care. Radiographs showed successful alignment, and the patient gradually resumed her daily activities. The patient had an uneventful recovery, and postoperative radiographs showed good alignment in all planes. Conclusions: The hyperlaxity associated with Down syndrome makes the incidence of HAV more frequent, and TMJ fusion is preferable to correction by osteotomy. The modified Lapidus technique with frontal plane rotational correction could be a good technique to achieve satisfactory correction in patients with severe HAV deformity and flexible valgus flatfoot associated with ligamentous hyperlaxity. TMJ fusion is indicated when severe or recurrent rotational component is observed in X-rays.

Objective: To present a novel method called triplanar chevron osteotomy to treat hallux valgus (HV). Methods: This is a retrospective study. In this study, the CT data of HV patients with painful callosities were evaluated retrospectively between 1 June 2018 and 1 June 2020. CT data from 49 consecutive patients (59 feet) with HV were evaluated. The average age at the time of surgery was 49.6 years (range, 30-63 years). The apex of the chevron osteotomy procedure was located at the center of the first metatarsal and was defined as the line formed by the central point perpendicular to the fourth metatarsal bone. The cut planes of the plantarward oblique chevron osteotomy (POCO) were defined as follows: chevron osteotomy along with 20 of plantarward obliquity. The triplanar osteotomy incision was made using the POCO method, with the direction inclined by 10 distally. The intermetatarsal angle (IMA), the HV angle (HVA), the projection of the second metatarsal (PSM), the metatarsal protrusion index (MPI), and the metatarsal protrusion distance (MPD) were all calculated before and after the operations. The length of the first metatarsal was measured and calculated with an equation. Results: The results showed that the HVA was significantly decreased after surgery (32.7 AE 4.6 vs 14.9 AE 2.1 , t = 25.583, P < 0.001) in the triplanar, traditional, and POCO groups. The IMA was also significantly decreased (14.7 AE 2.0) compared with the results before surgery (8.0 AE 1.1 , t = 22.739, P < 0.001) in these groups. Compared with traditional osteotomy and POCO, there were no differences in correcting deformities on axial planes for the HVA (14.5
