Displaced Neer Type IIB distal-third clavicle fractures-Long-term clinical outcome after plate fixation and additional screw augmentation for coracoclavicular instability.

BACKGROUND: Unstable Neer Type IIB fractures require meticulous surgical treatment. Thus, the aim of this study was to present long-term outcomes after plate fixation and minimally invasive coracoclavicular (CC) stabilization using screw fixation. METHODS: A consecutive series of patients with unstable Neer Type IIB displaced clavicle fractures, treated by open reduction and internal fixation (ORIF) with a plate and additional screw fixation for coracoclavicular ligament instability, was reviewed in order to determine long-term clinical and radiological outcome. RESULTS: Seven patients, six males and one female, with a mean age of 37 ± 8 years (median: 36 years; range, 28-51 years), were evaluated. At latest follow-up, after a mean of 67 months (range, 11-117 months), patients presented with the following mean scores: DASH: 0.57, ASES: 98.81, UCLA: 34.29, VAS: 0.43, Simple Shoulder Test: 11.57. However, two complications were observed: one case of implant loosening and one non-union. There were no differences observed between the CC distances comparing postoperative X-rays to those in final follow-up. In 25% of our patients early postoperative complications occurred. In all patients reoperation was necessary to remove the implanted screw. CONCLUSION: The results of the present study indicate that the treatment of Neer Type IIB lateral clavicle fractures with ORIF using a plate and additional CC screw fixation, leads to satisfying clinical and radiological outcomes in the long-term. However, considering an early postoperative complication rate of 25% and a 100% rate of secondary surgery due to removal of the CC screw does not seem to justify this technique anymore.

Displaced juvenile Tillaux fractures : Surgical treatment and outcome.

BACKGROUND: Approximately 15 % of all juvenile injuries of the long bones involve the epiphyseal growth plate, and 2.9 % of these are juvenile Tillaux fractures. The Tillaux fracture is of great importance because it involves a major weight-bearing articular surface. Treatment protocols in the literature are not uniform for this kind of fracture, and numerous case reports can be found describing various treatment methods. The aim of this study was to present the clinical outcome at long-term follow-up after treatment of displaced Tillaux fractures. METHODS: In all, 168 children and adolescent patients with physeal injuries of the distal tibia were treated from 2003 to 2012. Seven patients were identified as having Tillaux fractures requiring surgical treatment and therefore were included in our study and evaluated retrospectively. RESULTS: Seven patients with Tillaux fractures underwent surgical reconstruction by open or closed reduction. Excellent results were achieved in 90 % of the patients, with a mean Foot and Ankle Score at the last follow-up of 98.71. CONCLUSION: Anatomical reduction is required for every displaced epiphyseal fracture via open reduction and internal fixation, especially in cases with ≥2 mm fragment displacement. Plaster cast immobilization and non-weight-bearing mobilization for at least 4 weeks might be a good way of ensuring optimal surgical results and preventing complications.

Clinical and functional outcome after anterior cruciate ligament reconstruction using the LARS™ system at a minimum follow-up of 10 years.

BACKGROUND: Since the 1980's several artificial ligaments were used for reconstruction of the anterior cruciate ligament (ACL) serving different complications. The aim of this study was to assess the clinical and functional outcomes of primary ACL reconstruction using the Ligament Augmentation Reconstruction System (LARS™) with a minimum follow-up of 10-years. The LARS™ presents a synthetic material consisting of non-absorbing polyethylene terephthalate fibres used for ligament reconstruction. METHODS: Outcomes of 18 patients who underwent arthroscopic ACL reconstruction using the LARS™ system between 2000 and 2004 with a minimum follow-up of 10 years were observed. The International Knee Documentation Committee score (IKDC), Visual Analog Scale (VAS), Lysholm score, and Tegner Activity Scale were assessed. Clinical assessment was performed by Lachman testing, assessment of side-to-side difference on KT-2000 testing and plain radiography evaluation of osteoarthritis. RESULTS: There were seven males and 11 females, mean age 29 years (range, 18 to 44 years) and a mean follow-up of 151.5 months. Five patients (27.8%) sustained a re-rupture of the LARS™ system and underwent revision surgery after a mean time of 23 months and four patients (22.2%) presented with a re-rupture. The average IKDC score was 76.60 ± 18.18, the average Lysholm score was 88.00 ± 10.07 and the average Tegner activity score was five at final follow-up. CONCLUSION: Our results indicate that the LARS™ system should currently not be suggested as a potential graft for primary reconstruction of the ACL. In special cases, however, the LARS™ system can serve as an alternative graft.
