Objective: To describe and quantify the complications arising in consecutive neuropathic patients undergoing partial longitudinal amputations of the foot. Method: A retrospective study was conducted with data collected from the medical records of patients monitored at the Insensitive Foot Clinic of the Foot and Ankle Group of our institution who underwent partial amputation of foot rays from 2000 to 2016. Results: A total of 28 patients met the inclusion criteria, with a total of 31 amputated/partially amputated feet. Of these, 18 (58.1%) feet were amputated/partially amputated due to diabetes, seven (22.6%) due to leprosy, two (6.5%) due to alcoholic neuropathy, two (6.5%) secondary to traumatic peripheral nerve injury, and two (6.5%) due to other causes. Fifth ray amputation was the most frequent type (n=12). The cause of amputation was the presence of an infected ulcer in 93.6% of the samples. At a mean follow-up time of 60 months, 13 (41.9%) feet required new amputations—five (38.5%) transtibial, five (38.5%) transmetatarsal, two (15.4%) of the toes, and one (7.7%) at Chopart's joint. Patients with diabetes had a 50.0% reamputation rate. Patients who initially underwent amputation of the fifth ray had a 58.3% reamputation rate. Conclusion: Partial longitudinal amputation of the foot in neuropathic patients exhibited a high reoperation rate, especially in patients with diabetes or in patients with initial amputation of the peripheral rays. Declaration of interest: The authors have no conflicts of interest.

The paper describes the biomechanical behavior of a cervical implanted unit (CIU) in two conditions: during the physiological and extreme loading. In order to reveal these behaviors, the anatomical structure composed by the C2 and C3 cervical vertebras was implanted using a plate-screws metal structure. The implant was design to perform dynamical, by allowing longitudinal, transversal and rotational movements. The physiological conditions were simulated by the pulsatory negative loading, while the extreme loading was simulated by the alternant symmetrical loading. The tests reveal two behaviors: the durability of the CIU in the physiological loading conditions and the failure of the structure under extreme load.

Abnormal Pattern

Nearly 3% of individuals worldwide experience pain, immobility, and compromised quality of life due to knee osteoarthritis (OA)1. It has been widely accepted that joint mechanics play a critical role in the initiation and progression of knee OA2. A shift away from the normal joint motion, for example due to injury or malalignment, is believed to produce an abnormal pattern of cartilage loading that creates unusual and damaging stresses within the tissue. Accurate knowledge of cartilage’s normal mechanical response to physiological loading—and particularly the regional dependence of this response—is critical to successfully testing this theory. To our knowledge, little is known about the regionally-dependent mechanical response of healthy human tibial cartilage under physiological loading conditions. There is also a compelling need for more accurate cartilage data to be integrated into computational simulations of the knee joint. Hence, the purpose of this study was two-fold: 1) to characterize the typical stress-strain response of tibial cartilage at 21 locations across the tibial plateau when subjected to loading representative of human walking, and 2) to demonstrate that these 21 sites can be reduced to a small number of regions displaying significantly different average moduli.
