Abstract Background All current total hip arthroplasty (THA) systems are modular in design. Only during the operation femoral head and stem get connected by a Morse taper junction. The junction is realized by hammer blows from the surgeon. Decisive for the junction strength is the maximum force acting once in the direction of the neck axis, which is mainly influenced by the applied impulse and surrounding soft tissues. This leads to large differences in assembly forces between the surgeries. This study aimed to quantify the assembly forces of different surgeons under influence of surrounding soft tissue. Methods First, a measuring system, consisting of a prosthesis and a hammer, was developed. Both components are equipped with a piezoelectric force sensor. Initially, in situ experiments on human cadavers were carried out using this system in order to determine the actual assembly forces and to characterize the influence of human soft tissues. Afterwards, an in vitro model in the form of an artificial femur (Sawbones Europe AB, Malmo, Sweden) with implanted measuring stem embedded in gelatine was developed. The gelatine mixture was chosen in such a way that assembly forces applied to the model corresponded to those in situ. A study involving 31 surgeons was carried out on the aforementioned in vitro model, in which the assembly forces were determined. Results A model was developed, with the influence of human soft tissues being taken into account. The assembly forces measured on the in vitro model were, on average, 2037.2 N ± 724.9 N, ranging from 822.5 N to 3835.2 N. The comparison among the surgeons showed no significant differences in sex (P = 0.09), work experience (P = 0.71) and number of THAs performed per year (P = 0.69). Conclusions All measured assembly forces were below 4 kN, which is recommended in the literature. This could lead to increased corrosion following fretting in the head-neck interface. In addition, there was a very wide range of assembly forces among the surgeons, although other influencing factors such as different implant sizes or materials were not taken into account. To ensure optimal assembly force, the impaction should be standardized, e.g., by using an appropriate surgical instrument.

Necrotising soft tissue infection is a rare and rapid process with devastating consequence. We report one case of necrotising soft tissue infection in a bilateral upper limb with uncommon oral bacteria. Radiological imaging revealed the presence of gas in upper limb soft tissues, and an MRI showed the localised signal changes in the biceps muscle of the right upper arm, and the subcutaneous tissue of the left elbow. The patient was treated with surgical resection of the infected muscle and wide debridement of the subcutaneous tissue. Antibiotics were initiated. The patient recovered immediately without functional deficit. The unique features of this patient were possible to observe in the progression of the necrotising soft tissue infection in the bilateral upper limb with intentional injection of oral bacteria, and the effect of biceps brachii resection in a prime age worker.

Os defeitos mandibulares devido à ressecção de lesão óssea interferem a harmonia e estética facial comprometendo a qualidade de vida dos pacientes. Grandes defeitos exigem planejamento minucioso, principalmente quando lançamos mão de enxertos e placas de reconstrução, evitando assim resultados insatisfatórios ou até mesmo sequelas. Apesar de algumas classificações dos defeitos mandibulares vêm sendo discutidas ao longo dos anos, ainda não há um protocolo definido para reconstrução mandibular. O uso de prototipagem na Cirurgia Bucomaxilofacial tem se tornado cada vez mais frequente; a precisão da reconstrução, diminuição do tempo de cirurgia reflete em recuperação mais rápida do paciente. Mesmo com a ferramenta da prototipagem, grandes lesões e perdas ósseas permanecem como grande desafio ao cirurgião.  O objetivo deste trabalho é relatar um caso clínico de reconstrução mandibular no qual houve a necessidade de ser tratado com remoção de placa de reconstrução e nova reabilitação cirúrgica do paciente.Descritores: Mandíbula; Reconstrução Mandibular; Modelos Biológicos.ReferênciasSantos LCS, Seixas AM, Barbosa B, Cincura RNS.
