Article Abstract
Background: Reconstruction of forefoot defects often necessitates free tissue transfer due to the limited availability of local tissue. Microsurgical reconstruction of the forefoot remains challenging, as it requires durable yet thin soft-tissue coverage for functional restoration. This study aimed to evaluate the efficacy of free thin perforator flaps for forefoot reconstruction, with a focus on functional outcomes.
Methods: Records of patients who underwent microsurgical forefoot reconstruction between March of 2020 and September of 2023 were reviewed. Development of postoperative complications and functional outcomes were evaluated.
Results: In total, 53 patients (mean age, 62.7 years) were analyzed. The most common cause of defects was oncologic surgery, followed by chronic wound, with a majority involving the plantar side. The superthin anterolateral thigh flap and superficial circumflex iliac artery perforator flap were predominantly used. The median flap thickness was 4.0 mm. Digital vessels were the most frequently used as recipients. All but one flap survived, resulting in a success rate of 98.1%. Postoperative flap site complications developed in 20 patients, the majority of which resolved with conservative treatment. The median hospital stay was 8.0 days, and the mean time for initiating weight-bearing ambulation was 12.4 days. In the postoperative Foot Function Index questionnaire survey, the overall score was 9.41, showing minimal impairment, and it did not differ according to defect size or location. A secondary debulking operation was needed in 7 patients.
Conclusion: Use of thin free perforator flaps might provide reliable outcomes with rapid recovery and excellent postoperative function in forefoot reconstruction.
Clinical Question/level Of Evidence: Therapeutic, IV.

Background: Over the last 30 years, total ankle arthroplasty (TAA) has become a viable surgical option for end-stage ankle arthritis. The aim of TAA is to relieve pain and preserve ankle joint range of motion, which, by definition, shields adjacent joints. Alignment is essential for the longevity and survival of TAA, since malalignment of TAA components can cause abnormal loading patterns with subsequent polyethylene wear and early implant failure.

Objective: To verify the utility and accuracy of periwound regional oxygen saturation (rSO) as a wound healing predictor of toes in patients with chronic limb-threatening ischaemia (CLTI), and compare the results with skin perfusion pressure (SPP) measurements.
Method: Patients with hard-to-heal (chronic) toe wounds and CLTI, and who had undergone toe rSO (near wound), forefoot rSO and SPP measurements, were retrospectively selected. Following the measurements, the patients were treated conservatively, and the progress of wound healing was evaluated 28-91 days after the rSO/SPP measurements.
Microsurgical Foot Reconstruction in Children Affected by Lawn Mower Injury.

From the Faculty of Medicine, Johannes Kepler University, Linz, Austria.
Background: Lawn mower injuries can cause limb-threatening wounds in the lower extremities of children. Although most cases require only basic wound treatment, a minority need microsurgical and orthopedic reconstruction for limb salvage. These procedures remain complex owing to small vessel diameter, increased vasospasticity, limited postoperative compliance, and continued growth in children.

Background: Total hip arthroplasty (THA) is a surgery widely used to reduce pain, improve function and quality of life in older people after femur fracture due to osteoporosis. The evident success of THA, especially in the long term, continues in relation to the different types of surgical approach, given the little understanding in older people. The aim of this study was to evaluate and compare the effect of THA between two surgical access routes, anterior and posterolateral, on the clinical, functional, and biomechanical parameters of older people after osteoporotic femur fracture.

Background: Hallux abductovalgus, or bunion deformity, is a common forefoot condition with numerous described techniques for surgical correction. Minimally invasive surgery (MIS) is gaining popularity in the foot and ankle community; however, limited data exists regarding the degree of correction achievable with MIS Akin osteotomies.
Purpose: To compare the angular and length changes produced by oblique and transverse Akin osteotomies using two burr sizes (2.
