PurposeThe optimal surgical treatment of displaced type B and C fractures of the proximal humerus in the elderly remains controversial. Good clinical results have been reported by plating these fractures as well as a high rate of complications. Our retrospective study aims to evaluate clinical recovery and complications using the S3 locking plate in elderly patients.MethodsFifty-one patients older than 65 years of age, with a complex proximal humeral fracture type B or C (AO classification system), were included. Patients have been followed up for a minimum of 12 months. We assessed callus formation, radiological results, clinical outcome (according to the Constant Shoulder Score System) and complications. Any difference in the clinical recovery among the 2 types of fracture pattern (B and C) was investigated.ResultsThe mean time of fracture healing was 12.4 weeks. The mean Constant score at 3, 6 and 12 months was 68, 73 and 75 respectively. No statistically significant difference in the clinical outcome was observed between the B and C fracture patterns (p > 0.05). We noticed an overall of 5 complications (9.8%). There was no need to revision any of the implants.ConclusionAnatomic reduction and proper plate positioning are essential for minimizing implant-related complications. In our experience the S3 angular stability system offers a proper osteosyntesis and a good clinical recovery with a low rate of complications.
Fracture of bilateral capitulum humeri is a very rare injury. We present a case of a 38-year-old woman, affected by a shear fracture of bilateral capitellum after a motorcycle accident. Intervention was carried out through a lateral approach on both sides and direct fixation of the fragment with headless screws. Consolidation was achieved and no signs of avascular necrosis occurred at 24 months of follow-up. The patient returned to her previous activities with no functional limitations. To the best of our knowledge, only four cases are reported describing different types of treatment and postoperative period of cast immobilization. According to our review of the literature regarding capitellar fractures, we preferred an immediate postoperative rehabilitation of the elbow, following the stable osteosynthesis.
Oxaliplatin-fluoropyrimidine combination therapy is the gold standard treatment for patients with stage III colorectal cancer (CRC); however, treatment duration is now under re-evaluation. The aim of the study was the evaluation of the non-inferiority of three over six months treatment with FOLFOX or CAPOX, in stage III CRC patients. Peripheral blood samples from 121 patients were collected, at three time points during treatment and evaluated for circulating tumor cells (CTCs) and microbial DNA detection (16S rRNA, Escherichia coli, Bacteroides fragilis, Candida albicans). Of all patients, 41.3% and 58.7% were treated with FOLFOX and CAPOX, respectively. CTCs were significantly decreased and increased after three and six months of treatment, respectively. CAPOX tends to reduce the CTCs after 3 months, whereas there is a statistically significant increase of CTCs in patients under FOLFOX after 6 months. A significant correlation was demonstrated between microbial DNA detection and both CTCs detection at baseline and CTCs increase between baseline and three months of treatment. To conclude, the current study provides additional evidence of non-inferiority of three over 6 months of treatment, mainly in patients under CAPOX.
Background: The treatment of distal femur fractures represents a challenging task. General and local factors, including bone quality, articular surface involvement, fracture comminution, associated soft tissue injuries and ultimately fixation system, all play a role in the final clinical outcome. Current surgical approaches often undermine patellar vascularization and integrity of the extensor apparatus, not guaranteeing sufficient visualization of the medial condyle. This technical note presents the efficacy and safety a new surgical technique to address distal femoral fractures. Methods: The original "swashbuckler" surgical approach was modified in order to obtain a better visualization of the lateral and medial femoral condyles without affecting the knee extensor mechanism and the anastomotic arterial supply of the patella. This modified surgical approach was utilized in a consecutive series of patients presenting with a Müller AO 33 distal femur or periprosthetic fracture of the knee. The final outcome was recorded according to a functional evaluation scoring system.Results: Twelve patients (2 males and 10 females) with a mean age of 67,8 years (min. 18; max 90 years) were included in this series. The same, modified "swashbuckler" surgical approach was applied in all cases. Multiple internal fixation techniques, including a single lateral plate, a combination of a lateral and medial plate, a single lateral plate associated with lag screws, were used to obtain a satisfactory stabilization of the fracture site. All patients were reviewed at a minimum one-year follow up (median 15 months): all patients regained their level of activities of daily living. No major intraoperative or postoperative complications were recorded. Conclusions: The modified swashbuckler approach allows anatomical reduction and appropriate fixation with minimal severance of the blood supply to the patella and ensures rapid weight bearing resumption thanks to an intact extensor mechanism.
