We analyzed 11 right wrists and 10 left, of which 57.1% corresponded to the dominant limb and 42.9% to the non-dominant.

The radiographic study allowed us to classify the DR fracture, as well as to rule out other lesions. We evaluated ulnar variance and radial tilt. We also obtained a computed tomography (CT) scan in those cases requiring an extension of the imaging study.</p></span><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0075">Surgical technique</span><p id="par0055" class="elsevierStylePara elsevierViewall">Under general and regional anesthesia and applying ischemia we proceeded to carry out a volar approach to the DR fracture and synthesis with a screw plate. Following the osteosynthesis we carried out a clinical exploration of DRUJ stability, through volar and dorsal displacement of the radius with a stabilized ulna. All the patients in our series presented clinical DRUJ instability upon exploration, so our team considers this to be an essential criterion for indication of arthroscopy. Next, we performed a dry diagnostic and therapeutic arthroscopy using a wrist traction tower system (Acumed<span class="elsevierStyleSup">®</span>, USA). The arthroscopy began with the identification of the 3–4 portal, through palpation of Lister's tubercle in the radius. We performed a skin incision and then deepened it bluntly until the radiocarpal joint was reached. We then introduced the lens and light source through it. Under direct visual control we identified the 6 R portal, in a radial position to the <span class="elsevierStyleItalic">extensor carpi ulnaris</span>, which allowed us to manipulate the ulnar joint surface. We then conducted a systematic visual evaluation of the radiocarpal ligamentous structures and joint surfaces in all patients. We verified the reduction of the DR fracture obtained with osteosynthesis and examined the TFC, as well as the scapholunate, radiocarpal and ulnocarpal ligaments. In this series we diagnosed 5 patients with scapholunate joint lesion during the arthroscopic evaluation, and treated it during the same surgical intervention through ligamentopexy, reinsertion or fixation with a percutaneous osteosynthesis, with no associated dorsal pathway in 95.2% of the cases. We continued the examination verifying the stability and resistance of the TFC.</p><p id="par0060" class="elsevierStylePara elsevierViewall">This was basically assessed through 2 tests: the “Trampoline test”, which evaluates tension and texture, and the “Hook test”, which evaluates foveal disinsertion. The TFC was affected in its ulnar side in all cases in this study.</p><p id="par0065" class="elsevierStylePara elsevierViewall">Once the diagnosis and therapeutic indication had been established, we created an accessory portal to 6 R, between the anterior and posterior ulnar tendons (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). We introduced the instrumentation through this portal and, under direct visual control, identified the point selected to reanchor the TFC in the ulnar fovea. This point was first marked with a guide needle, then drilled with the drill bit of the device, and then verified radiographically. We also used the same approach to pass a monofilament 3/0 thread by the TFC (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>a and b) following the outside-in technique (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>). This thread was subsequently replaced by the 0/0 thread of the anchor system. We loaded the 2.8<span class="elsevierStyleHsp" style=""></span>mm PopLok implant (ConMed<span class="elsevierStyleSup">®</span>, USA) (<a class="elsevierStyleCrossRef" href="#fig0020">Fig. 4</a>), placed in its foveal location and tensed without traction (<a class="elsevierStyleCrossRef" href="#fig0025">Fig. 5</a>) and verified the stability of the reanchor. We then proceeded to close the volar incision but left open the arthroscopy portals, covered with sterile gauzes. We placed a cushioned bandage in all patients with a forearm cast to fix it for 3 weeks or extend immobilization depending on the associated lesions present.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><elsevierMultimedia ident="fig0015"></elsevierMultimedia><elsevierMultimedia ident="fig0020"></elsevierMultimedia><elsevierMultimedia ident="fig0025"></elsevierMultimedia><p id="par0070" class="elsevierStylePara elsevierViewall">The time of immobilization varied between 2 and 24 days, with a mean value of 24.35<span class="elsevierStyleHsp" style=""></span>±<span class="elsevierStyleHsp" style=""></span>11 days.
