[Show abstract][Hide abstract] ABSTRACT: Hallux valgus (HV) is one of the most common deformities in podiatric and orthopedic practice. Plantar pressure technology has been widely used in studying the pressure distribution in HV patients for better assessment to plan interventions. However, previous studies produced an array of controversial findings and most of them only focused on the forefoot.
We examined the dynamic changes of foot pressure of the whole foot with a large-sample investigation (229 patients and 35 controls). Foot pain, which has been largely neglected previously, was used to group the participants.
Compared to healthy controls, patients had significantly higher loading of the first and second metatarsals, where the transverse arch usually collapses, and significantly less loading of the hallux. Moreover, forces in most regions reached their maximum late, indicating a slow build-up of loading. Patients shortened the loading duration on their forefoot, loaded more on the medial foot starting from early foot contact, and delayed the medial-to-lateral load transition. Notably, nearly all these changes were more pronounced in patients with pain.
Biomechanical changes in HV patients are not only caused by physical deformity but also by modified neural control strategies, possibly to alleviate discomfort and to accommodate the foot deformity. Our results suggest that dynamic evaluation of the whole foot and consideration of foot pain are necessary for the functional assessment of foot pressure in HV patients. The foot balance changes have important clinical implications.
[Show abstract][Hide abstract] ABSTRACT: To evaluate the efficacy and feasibility of the Chinese drugs for supplementing Qi and activating blood circulation in preventing DVT after big operations in orthopaedics and traumatology and observe the change of D-dimer before and after treatment.
Seventy patients ranging in age from 39 to 94 years who were treated by big operations in orthopaedics and traumatology were divided into two groups randomly. Traditional Chinese medinine (TCM) group (group A) and western medicine group (group B). On the 2rd day after operation d-dimer was tested from both groups and the patients in group A were given one dose of TCM every day and the patients in group B were subcutaneously injected low-molecular-weight heparins calcium (LMWH). On the 8th after operation d-dimer was tested again from both groups. The parameters, such as the incidence of DVT and pulmonary thromboembolism, bleeding condition, were evaluated respectively.
The D-dimer decreased in group A and had significant difference (P < 0.05), group B had no significant difference, there was also no significant difference between two groups. DVT was found in 1 patient in group B (1/35). Petechiae were found in 10 patients in group A (10/35) and in 26 patients in group A (26/35), which had significant difference (P < 0.05).
Both the Chinese drugs and anti-coagulation drug can prevent the incidence of DVT effectively, and Chinese herbs are feasible in the prevention of DVT.
