Risk of Volar Locking Plate Removal After Distal Radius Fractures: Time-to-Event Analysis.

PURPOSE: The primary purpose of this study was to describe the rate of volar locking plate (VLP) removal after distal radius fracture and how long it takes for the risk of VLP removal to stabilize. The secondary purpose was to describe the reasons for VLP removal and analyze the relationship between it and the Soong index. METHODS: This was a single-center retrospective cohort study. Patients aged >18 years with distal radius fracture who underwent VLP fixation were included. Hardware removal, time until VLP removal, and the primary reason for removal were recorded. The implant prominence was measured as described by Soong. We used Kaplan-Meier curves and risk tables to describe the risk of VLP removal and variation over time. Multivariable logistic regression was used to assess the relationship between Soong grade and VLP removal. RESULTS: A total of 313 wrists were included. There were 35 cases of VLP removal, with an overall incidence of 11.2% at 15 years of follow-up. The incidence rate was 1.2 per 100 individuals per year for the entire cohort. The risk of VLP removal decreased from 6.2% in the first postoperative year to 1.7% in the second year and 1.4% in the third year. Beyond that, the rate remained <1% per year throughout the follow-up period. The median hardware removal time was 11 months. The main reasons for VLP removal were tenosynovitis, implant-associated pain, and screw protrusion. We found no association between Soong grade and VLP removal. CONCLUSIONS: Volar locking plate removal after distal radius fracture was more common in the first year after surgery and remained notable until the third year. Regular monitoring and patient education to assess possible complications related to hardware are important during this period. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Subtalar arthroereisis in pediatric flexible flat foot: Functional and radiographic results with 5 years of average follow-up.

The aim of this retrospective study is to evaluate the clinical-functional and radiographic results in pediatric patients with painful and disabling Flexible Flat Foot (FFF) refractory to conservative treatment who underwent percutaneous subtalar arthroereisis with a Maxwell Brancheau Arthroereisis® (MBA) implant. Patients aged 8-14 years old with a minimum follow-up of 24 months were included. A pre and postoperative radiographic evaluation was carried out analyzing Meary's angle, internal Moreau-Costa-Bartani´s angle, Talar declination angle, Calcaneal Pitch, Kite's angle, Talar-1st metatarsal angle, and Talonavicular coverage angle. In those patients with more than 5 years of follow-up, the development of subtalar osteoarthritis was evaluated. A clinical-functional evaluation was carried out using the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot rating scale. Pre and postoperative pain was evaluated using the visual analog scale (VAS). Postoperative complications were described. Fourteen patients (19 feet) met the inclusion criteria. The mean age at surgery was 12 years old with a mean follow-up of 68.26 months. All radiographic angles improved significantly. No signs of subtalar osteoarthritis were identified. The mean pre and postoperative pain according to VAS was 7.05 and 0.77 respectively. The mean pre and postoperative AOFAS was 75.42 and 97.05 respectively. One female patient had persistent pain in both feet (VAS = 4). However, she was able to do sports and daily life activities without restrictions. None of the implants needed to be removed due to intolerance or pain. Subtalar arthroereisis seems to be effective to improve the clinical-functional and radiographic parameters in moderate pediatric FFF.

[Conservation surgery and early rehabilitation in massive necrotizing fasciitis of the lower limbs] / Cirugía de conservación y rehabilitación temprana en fascitis necrotizante masiva de miembros inferiores.

Necrotizing fasciitis is a life-threatening infection. Early diagnosis and treatment are essential. Reconstruction techniques and rehabilitation protocols have been poorly described. The objective of this work is to describe the results of timely treatment for limb preservation and early rehabilitation in a case of massive necrotizing fasciitis of the lower limbs. We present a case of necrotizing fasciitis in the lower limbs, treated surgically with a negative aspiration system, muscle flaps, and skin graft. We describe his rehabilitation protocol and the results at one year of follow-up.

La fascitis necrotizante es una infección potencialmente letal. Es esencial un diagnóstico y tratamiento temprano. Las técnicas de reconstrucción y los protocolos de rehabilitación han sido escasamente descritos. El objetivo de este trabajo es describir los resultados del tratamiento oportuno para la conservación de miembros y la rehabilitación temprana en un caso de fascitis necrotizante masiva de miembros inferiores. Presentamos un caso de fascitis necrotizante en miembros inferiores, tratado quirúrgicamente mediante sistema de aspiración negativa, colgajos musculares e injerto cutáneo. Describimos su protocolo de rehabilitación y los resultados al año de seguimiento.
