Indications and limitations of the fixator TGF "Gex- @entity4682 " in XXXX .

@entity1 @entity174 @entity170 @entity4682 @entity6342 @entity158 @entity2530
The incidence of @entity174 of the humerus has increased exponentially in recent years. The most used classifications for humerus @entity174 are morphological (Neer), biological (AO/ASIF) and descriptive (Hertel). The types of surgical treatment for humerus @entity174 include prosthetic replacement and synthesis using different devices, including the Tension Guide Fixator (TGF), Gex- @entity4682 . External fixation for displaced @entity6342 avoids dissection and soft tissue stripping and has been reported by some authors to be associated with higher union rates, a lower incidence of @entity2530 , less scarring of the scapulohumeral interface, and faster rehabilitation compared with open reduction and internal fixation. Other authors have reported that external fixation does not ensure acceptable reduction and @entity174 stability, particularly in @entity1 with @entity170 . The external fixation technique involves the introduction of Steinmann's pin to keep manual reduction, the introduction of two K-wires in the humeral head, the removal of the Steinmann's pin, and the introduction of two fiches on the humeral shaft. Hub connectors are mounted on the wires and on the chips to connect the outer bar and tensioning system. A total of 84 @entity1 aged 42-84 years with @entity6342 (66% had two-part @entity174 ) were treated with Fixator TGF in this study from December 2007 to June 2012. The postoperative recovery was earlier and the active-assisted motion was less @entity158 than has been reported with other surgical techniques. The TGF was removed without anaesthesia at the outpatient clinic at a mean of 7 weeks (range 5-8 weeks) after surgery, and there was no loss of reduction or secondary displacement after removal. These results, after five years of experience, confirm that the best indication for this fixator is two- or three-part @entity174 because the device enables early active mobilisation. The limitations of this fixator are evident in @entity174 in which closed reduction is not possible and in three-part @entity174 with varus displacement because the TGF has less stability than other systems, such as the plate or cage. The short learning curve, reduced surgical time and risk, and low cost encourage the use of this technique.
