Arthroscopie des fractures extra-articulaires du radius distal : les fractures extra-articulaires sont aussi des traumatismes articulaires, à propos de 35 cas P. Croutzet Toulouse, France Adresse e-mail : [email protected] Introduction In articular distal radius fractures, arthroscopy has demonstrated benefits to diagnose and treat ligament injuries of the wrist, in particular for the triangular fibrocartilage complex (TFCC). For extra-articular radius fractures, this prospective series proposes to assess ligament injuries (especially TFCC) with a systematic wrist arthroscopy. Indeed, the two forearm bones work as a functional unit and the fracture of one bone often induces a fracture of the second one. When the fracture of the second bone does not occur, we can suspect a dissociative ligamentous injury between the 2 bones, especially a TFCC injury. This hypothesis was oriented by our recent series concerning TFCC injuries in Galeazzi fractures. Materials and methods Over a period of one year, 35 extraarticular distal radius fractures were operated on with systematic radiocarpal arthroscopy. Selected patients were younger than 65 years with recent closed surgical extra-articular radius fractures associated or not with an ulnar fracture. We used a locking anatomical compression plate, a 1.9 mm arthroscope with 3 systematic radio-carpal portals: volar radiocarpal, 3-4, 4-5 and an extra 6U portal for TFCC repair. A splint was kept for 3 weeks followed by an active/passive physiotherapy. Physical examination and X-ray were performed after 3, 6 and 12 weeks. Analysis criteria were: – perioperative: ligament injuries, duration of surgery; – postoperative: pain, wrist motion (F/E◦ ; P/S◦ ), grasp strength, time off work and sports, X-ray analysis (reduction, consolidation, secondary displacement). Results Five patients were only reviewed twice. The TFCC was injured in 21 cases: – with ulnar fractures (n = 20): 8 injuries including 6 radial lesions; – without ulnar fracture (n = 15): 13 injuries including 9 ulnar lesions. One radial TFCC injury and all ulnar lesions were repaired. About strength and motion: – after 3 weeks: F/E: 60/55◦ , P/S 60◦ /70◦ , grasp 23%; – after 6 weeks: F/E: 75/70◦ , P/S 75◦ /80◦ , grasp 52%; – after 12 weeks: F/E: 85/80◦ , P/S 80◦ /80◦ , grasp 88%. We noticed 30 anatomic reductions and none secondary displacement. Time off work was 4 weeks (0–7). Discussion and conclusion Extra-articular radius fractures without ulnar fracture were often associated with TFCC injuries, rather ulnar. Both bone fractures were less associated with TFCC injuries, rather radial. This study is a first step demonstrating a diagnosis interest in systematic wrist arthroscopy for extra-articular radius fractures. In order to demonstrate a prognosis interest in rapidity and quality of recovery, a further comparative study with pronosupination strength and power measurement should be necessary.

Introduction Galeazzi fracture is a trauma associating diaphysal radius fracture and dislocation or subluxation of the distal radio-ulnar joint (DRUJ). Despite an anatomic reduction of the radius, DRUJ impairment, especially injury of triangular fibrocartilage complex (TFCC) may lead to partial instability with secondary pain and stiffness. This prospective case series proposes to perform wrist arthroscopy for Galeazzi fractures in order to diagnose ligamentous injuries and to enable their reparations. Materials and methods Over a period of 18 months, 7 recent Galeazzi closed fractures were operated on with wrist arthroscopy. We used a locking compression plate, a 1.9 mm arthroscope with 3 radio-carpal portals: 3-4, 4-5 and 6U. A dorsal forearm splint was kept for 3 weeks followed by an active/passive physiotherapy. Physical examination and X-ray were performed after 3, 6 and 12 weeks. Analysis criteria were: – perioperative: ligament impairment, duration of surgery; – postoperative: pain, wrist motion (flexion/extension; prono/suppination), grasp strength, time off work and sports, X-ray analysis (reduction, consolidation, secondary displacement). Results All patients were reviewed 3 times. The triangular ligament was injured in all cases, 3 cases in the radial part, 3 cases in the ulnar part and one both side. All ulnar injuries were repaired systematically. The radial TFCC injuries were only repaired when DRUJ instability persisted despite good reduction of the radius. After osteosynthesis of the radius, DRUJ remained instable in 3 cases, one ulnar lesion, one radial and one both side. The reparation of the triangular ligament improved stability of the DRUJ in 2 cases, one case remained instable despite TFCC reparation. About strength and mobility: – after 3 weeks: F/E: 50/60◦ , P/S 45◦ /45◦ , grasp 20%; – after 6 weeks: F/E: 80/80◦ , P/S 70◦ /60◦ , grasp 45%; – after 12 weeks: F/E: 85/80◦ , P/S 80◦ /75◦ , grasp 80%. We noticed 7 anatomic radius reductions and no secondary displacement. A dorsal DRUJ subluxation was noticed despite the ulnar TFCC repair; none nonunion was reported. Time off work was 7 weeks (4–10). Discussion and conclusion Functional mobility was regained after 6 weeks, accompanied by good strength. TFCC reparation participate in DRUJ stabilization but was not always sufficient to fully stabilize the DRUJ. A next study with DRUJ MRI and prono-supination strength measurement should participate to demonstrate further benefits of TFCC reparation in Galeazzi fractures. A lesion of the TFCC was noticed in all cases suggesting that TFCC lesion could occur in some other extra-articular distal radius fractures.

Arthroscopy for Bennett fractures: A prospective series of 8 cases Traitement arthroscopique des fractures de Bennett : à propos de 8 cas P. Croutzet Toulouse, France E-mail address: [email protected] Introduction The Bennett fracture is a trauma associating an intra-articular fracture of the first metacarpal and a trapeziometacarpal joint subluxation; the prognosis of this trauma depends on quality of reduction and preservation of ligamentous anatomy. This prospective case series aims at demonstrating that arthroscopic procedure for Bennett fractures can improve both the quality of reduction and the preservation of ligamentous anatomy. Materials and methods Over a period of 18 months, 8 intraarticular fractures of the first metacarpal were operated on with arthroscopy. We only retained recent (< 21 days) trauma without extra-articular fracture. We used 2 portals, a 1.9 mm arthroscope,
