POMC method was a reproducibly reliable method, offering better functional outcome, lower incidence of complications, and reoperations, as compared with standard OMATB group for transverse patellar fractures. Nevertheless, it is not recommended for severely comminuted fractures.
Under the control of arthroscopy and fluoroscopy, we successfully treated 21 displaced transverse patellar fractures by percutaneously osteosynthesis. This is a safe and reproducible method for transverse patellar fractures. However, it is not indicated for severely comminuted fractures.
Our study found that distal linear osteotomy was a more reliable reconstruction with equivalent function outcomes than an oblique diaphyseal osteotomy. Additional fixation may be necessary to decrease sagittal malunion in distal Bösch osteotomy.
This study found that SDA using fresh-frozen femoral head allograft without an orthobiological agent was cost-effective and may have outcomes comparable to those using autograft or allograft enriched with orthobiological agents.
Background: Adult acquired flatfoot deformity (AAFD) and hallux valgus (HV) are common foot and ankle deformities. Few studies have reported the changes in radiographic parameters of HV after reconstructive surgery for AAFD. This study aimed to evaluate the changes in radiographic parameters of HV and analyze the risk factors for increased HV after correction of AAFD. Methods: Adult patients with flexible AAFD who underwent similar bony procedures including medializing calcaneal osteotomy and Cotton osteotomy were included. Radiographic parameters were measured on weightbearing radiographs preoperatively, postoperatively, and at the final follow-up. Patients were divided into hallux valgus angle (HVA) increased and HVA nonincreased groups; logistic regression analysis was performed to identify risk factors affecting increased HV. Results: Forty-six feet of 43 patients were included. After AAFD reconstructive surgery, the tibial sesamoid position improved by 1 grade, but the HVA increased 4 degrees in average. Further, 21 of 46 feet (46%) showed an HVA increase ≥5 degrees immediately after AAFD correction surgery. Preoperative talonavicular coverage angle <21.6 degrees was a risk factor associated with HV increase immediately after the surgery. Conclusion: In this case series, using plain radiographs to measure standard parameters of foot alignment, we found the association between AAFD correction and HV deformity measures somewhat paradoxical. Correction of overpronation of the hindfoot and midfoot appears to improve the first metatarsal rotational deformity but may also increase HVA. A lower preoperative talonavicular coverage angle was associated with an increase of the HVA after surgery. Level of Evidence: Level IV, case series study.
Rationale:Pulmonary embolism is a potentially devastating medical condition. Although deep-vein thrombosis is the most common etiology, a nonthrombotic pulmonary embolism is not uncommon.Patient concerns:A 45-year-old woman was admitted to our hospital for progressive effort dyspnea for 3 weeks.Diagnosis:Echocardiography revealed a mobile mass extending from the right atrium to the bilateral proximal pulmonary artery. As the mass was no response to thrombotic therapy, intravenous leiomyomatosis was suspected. Computed tomography (CT) revealed a hypo-attenuated tumor extending from the ovarian vein to the pulmonary artery.Interventions:A 1-stage operation for the surgical removal of the tumor, right salpingo-oophorectomy and subtotal hysterectomy were performed. Surgical specimen was identified as uterine leiomyomatosis without malignant transformation.Outcomes:The patient was followed- up for 2 years and subsequent CT did not reveal any notable lesions.Lessons:Nonthrombotic pulmonary embolism is a potentially life-threatening complication. This case indicated intravenous leiomyomatosis should be considered in the differential diagnosis for certain cases. Complete surgical excision was the only curative treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
