Clinical Outcomes of Custom 3D-Printed Porous Metallic Implants for Reconstruction of Critical-Sized Bone Defects in the Ankle

May 7, 2026

This study investigates the clinical outcomes and complications associated with custom 3D-printed porous metallic implants used for ankle arthrodesis in patients with critical-sized bone defects. The authors report a high fusion rate of 83% but also highlight significant complications, particularly deep postoperative infections, which were linked to a higher likelihood of reoperation. The findings suggest that while custom cage implants show promise, further evaluation and comparison with traditional methods are necessary to improve treatment outcomes in this challenging area of foot and ankle surgery.

Comparison of Outcomes after Minimally Invasive Transverse Distal Metatarsal Osteotomy (MITO) and Proximal Phalangeal Osteotomy for Hallux Valgus With and Without Rheumatoid Arthritis: A Matched Cohort Study

May 4, 2026

The authors aimed to compare the radiologic and clinical outcomes of minimally invasive transverse distal metatarsal osteotomy (MITO) and complete proximal phalangeal osteotomy for hallux valgus correction in patients with and without rheumatoid arthritis (RA). The study found that both groups experienced significant improvements in radiologic parameters and noninferior pain relief, suggesting that MITO is a safe and effective joint-preserving surgical option for RA patients without advanced first metatarsophalangeal joint destruction.

Semiautomated Weight-Bearing CT-Based 3D Analysis of Normal Foot and Ankle in a Korean Population: A Comparison With European Data

Apr 30, 2026

This study aims to establish population-specific reference values for 3D foot and ankle parameters in a Korean cohort using weight-bearing computed tomography (WBCT) and to compare these values with existing European data. The authors found significant morphological differences between the Korean and European populations, highlighting the necessity for ethnic-specific reference values in clinical practice. These findings contribute to a foundational understanding of foot and ankle anatomy in East Asian populations, which can aid in diagnosis and surgical planning.

Crossed-Screw Configuration for Subtalar Arthrodesis: Clinical Outcomes of an Alternative Surgical Technique

Apr 30, 2026

This study investigates the clinical outcomes of a crossed-screw configuration for subtalar arthrodesis, aiming to address the technical challenges associated with traditional fixation techniques. The authors found that this alternative method resulted in high union rates and low complication rates, while also simplifying the surgical process and reducing the need for posterior heel incisions. Overall, the crossed-screw technique demonstrated successful outcomes, making it a viable option for subtalar arthrodesis.

Accuracy of Patient-Specific Instruments for Supramalleolar Osteotomies

Apr 30, 2026

The authors aimed to evaluate the accuracy of patient-specific instruments (PSIs) in performing supramalleolar osteotomies (SMOs) for correcting distal tibia deformities. Their study found that the post-operative corrections achieved using PSIs closely matched pre-operative simulations, with differences within 1°, indicating that PSIs facilitate precise execution of surgical planning. The results suggest that PSIs may enhance the technical accuracy of SMOs compared to traditional free-hand techniques, warranting further investigation into their clinical benefits.

Plain Radiographs Underestimate Tibiotalar Tilt in Progressive Collapsing Foot Deformity

Apr 30, 2026

The authors aimed to assess the accuracy of plain radiographs in evaluating tibiotalar tilt in patients with progressive collapsing foot deformity (PCFD) compared to weightbearing CT (WBCT). They found that plain radiographs significantly underestimate valgus tibiotalar tilt, with discrepancies largely due to inadequate visualization of anterior joint deformities. This study highlights the need for improved radiographic techniques or alternative imaging methods to enhance preoperative planning for PCFD.

Effect of the Reverse Cotton Osteotomy on First Metatarsal Position: A Cadaveric Study

Apr 30, 2026

This study investigates the impact of the reverse Cotton osteotomy (RCO) on the position of the first metatarsal in the correction of adult-acquired flatfoot deformities, specifically measuring changes in the talo-first metatarsal angle (Meary angle) through a cadaveric model. The results indicate that RCO significantly improves the Meary angle with 1-, 2-, and 3-mm wedge sizes, but not with a 4-mm wedge, suggesting that limiting the wedge size to a maximum of 3 mm may optimize surgical outcomes. These findings aim to provide guidance for surgeons in employing RCO to enhance postoperative results in flatfoot correction.

Surgical Helmet Systems Were Not Associated With Lower Operative Infection Rates After Total Ankle Arthroplasty: A Retrospective Cohort Study

Apr 30, 2026

This study aimed to determine whether the use of surgical helmet systems (SHS) during total ankle arthroplasty (TAA) reduces postoperative infection rates compared to conventional gowning. The analysis of 938 patients revealed no significant differences in overall surgical site infections or deep prosthetic joint infections between the two groups, indicating that SHS do not provide a protective effect against infections. Consequently, the authors suggest that the decision to use SHS should be based on individual surgeon preference rather than evidence of infection prevention.

Epidemiology and Clinical Characteristics of Os Intermetatarseum: A Systematic Review and Meta-analysis

Apr 29, 2026

The authors aimed to determine the prevalence and clinical characteristics of os intermetatarseum (OI), an accessory ossicle between the first and second metatarsals, which can sometimes lead to painful syndromes. Their systematic review and meta-analysis of 21 studies revealed a pooled prevalence estimate of OI at approximately 1.16% in the general population, with notable regional variations and the importance of recognizing OI to avoid misdiagnosis with other conditions.

Radiologic Progression of Talar Osteochondral Lesions With Subchondral Cyst: A Median 98-Month Observational Study

Apr 28, 2026

This study investigates the long-term radiologic progression of nonoperatively managed cystic osteochondral lesions of the talus (OLT) and aims to identify predictors of cyst progression while examining the relationship between radiologic changes and clinical outcomes. The findings reveal that most patients experienced minimal change in cyst volume over a median follow-up of 98 months, with significant predictors of progression including larger initial cyst volume, bone marrow edema, and wall breakage; however, changes in cyst size did not correlate with clinical symptoms. Notably, none of the cases progressed to osteoarthritis.
