To investigate the operative treatment of displaced intra-articular calcaneal fractures (DIACFs) using a combination of small lateral incision approach and internal fixation and allograft bone transplantation. Methods From January 2005 to December 2007, 28 patients with 34 DIACFs were treated with open reduction, allograft bone transplantationand internal fixation through a small lateral incision approach. Of them, there were 18 males and 10 females, aged 16-65 years. The disease course was 2 hours to 18 days. According to Sanders classification, there were 18 cases of type II fractures, 10 cases of type III fractures and 6 cases of type IV fractures. Results 22 patients with 28 DIACFs were followed up 18.5 months (13-28 months). The wound of 26 feet achieved primary heal ing, the acute rejection was found in 2 patients and developed wound compl ications. Both patients underwent further surgery prior wound heal ing. After the internal fixation were removed, factures was fixed with external fixator, closed continuous irrigation and drainage was employed. In the meantime, both patients received antibiotics and incisional dressing change. As a result, one achieved primary heal ing, the other developed delayed heal ing. Thepreoperative X-ray film showed that Bouml;hler angle was (6.19 ± 9.66)° and Gissane angle was (103.04 ± 15.03)°; the postoperative X-ray film demonstrated that Bouml;hler angle was (34.51 ± 5.89)° and Gissane angle was (112.18 ± 10.50)°; showing statistically significant differences (P lt; 0.05). The internal fixation of 12 patients (14 DIACFs) were removed at 6 -10 months after operation, Bouml;hler angle was (32.81 ± 5.10)° and Gissane angle was (110.81 ± 9.98)°. When compared with preoperative X-ray film, statistically significantdifferences (P lt; 0.05) was found, but there was no statistically significant differences (P gt; 0.05) when compared with normal X-ray film. According to the American Orthopedic Foot and Ankle Society evaluation system for ankle-hind foot, 3 feet scored 60-70 points, 10 feet 70-80 points, 12 feet 80-90 points and 3 feet 90-100 points. Conclusion Allograft bone transplantation is an option for management of DIACFs, because it enables satisfactory reconstruction of bone defects, allows met anatomic reduction and functional recovery, maintaining restoration of calcaneal height and anatomic reduction of the posterior facet.
To introduce the current situation of platelet-rich plasma (PRP) and its appl ication in orthopedics field. Methods The latest l iterature was reviewed, concerning the preparations of PRP, physiological mechanism and the latest appl ications in orthopedics field. Results PRP represent a new biotechnology for the stimulation and acceleration of tissue heal ing and bone regeneration. To succeed, some of the challenges need to be addressed including standardization and definition of the different PRP preparations, the complete characterization of the platelet released factors and proteins. Furthermore, well-designed studies and cl inical trials are needed to evaluate the potential therapeutic impact ofPRP. Conclusion PRP provides a novel appl ication for orthopedics field.
Patients undergoing maintenance hemodialysis are characterized with lower cardiorespiratory capacity and muscle atrophy, thus easily leading to a sedentary lifestyle. These patients are usually associated with lower quality of life and worse prognosis. Evidence indicates appropriate exercise rehabilitation plan could help maintenance hemodialysis patients achieve better health outcomes. However, there is still a lack of evidence data to precisely recommend exercise type, intensity, frequency and timing specially designed for maintenance hemodialysis patients. This article aims to summarize the existing expert consensus on exercise rehabilitation for maintenance hemodialysis patients, important considerations in the implementation process, factors that affect exercise rehabilitation, with a view to encouraging maintenance hemodialysis patients to participate in the development of appropriate exercise rehabilitation plan and maximize health benefits.
In 2020, chronic kidney disease has become one of the top 10 causes of death in the world. More and more evidence shows that proper exercise rehabilitation is beneficial to the health of patients with chronic kidney disease, which can improve the survival rate and slow down the decline of renal function. However, existing studies have significant differences in form, intensity, duration, and specific implementation methods of sports rehabilitation, which need to be further standardized and unified. This article introduces the impact of exercise rehabilitation on patients with chronic kidney disease and the clinical application of Chinese traditional exercises in patients with chronic kidney disease, and mainly discusses the application experience of exercise rehabilitation characterized by “Three-in-one Taiji” in the Department of Nephrology of West China Hospital of Sichuan University. It aims to provide a basis for the model innovation of integrated management of chronic kidney disease in China.
The incidence of sarcopenia and frailty in maintenance hemodialysis patients are high, and there are often comorbidities, which easily lead to more complications, thus increasing the hospitalization rate and reducing the quality of life of patients. This article reviews the definition, physiological mechanism, incidence and diagnosis, relationship and treatment strategies of sarcopenia and frailty in maintenance hemodialysis patients, in order to better prevent and intervene the occurrence of sarcopenia and frailty and provide a reference for prevention and treatment.
At present, the whole lifecycle management of vascular access for hemodialysis in China is still in its early stages. Faced with a large group of chronic kidney disease patients, hospitals at all levels lack systematic and continuous nursing management models. To address the issue of lacking continuous and effective nursing management of vascular access for dialysis during the period from hospitalization for autologous arteriovenous fistula surgery to outpatient maintenance hemodialysis treatment, this article introduces the background, specific implementation methods, and preliminary results of the new model of integrated medical and nursing follow-up management of vascular access for patients with hemodialysis during hospitalization and outpatient period constructed by the Wenjiang Hemodialysis Center of West China Hospital, Sichuan University. The purpose is to explore a new model for continuous and effective management of vascular access for hemodialysis patients.
