SummaryObjective: To describe the surgical technique of complex distal femoral deformity correction with the aid of stereolithography apparatus (SLA) biomodels, stabilized with locking plate fixation.Methods: Full-size replica epoxy bone bio-models of the affected femurs (4 dogs/5 limbs) were used as templates for surgical planning. A rehearsal procedure was performed on the biomodels aided by a guide wire technique and stabilized with locking plate fixation. Surgery performed in all dogs was guided by the rehearsal procedure. All pre-contoured implants were subsequently used in the definitive surgical procedure with minimal modification.Results: All dogs had markedly improved, with near normal functional outcomes; all but one had a mild persistent lameness at the final in-hospital follow-up examination (mean: 54.4 weeks; range: 24–113 weeks after surgery). All femurs healed without complications (mean: 34 weeks, median: 12 weeks; range: 8–12 weeks for closing osteotomies, and 26–113 weeks for opening wedge osteotomies). Long-term follow-up examination (mean: 28.6 months; range: 5–42 months) revealed all but one owner to be highly satisfied with the outcome. Complications were observed in two dogs: prolonged tibiotarsal joint decreased flexion that resolved with physical therapy. In one of these dogs, iatrogenic transection of the long digital extensor tendon was repaired, and the other had a peroneal nerve neurapraxia.Clinical significance: Stereolithography apparatus biomodels and rehearsal surgery simplified the definitive surgical corrections of complex femoral malunions and resulted in good functional outcomes.Online supplementary material is available for this paper at: http://dx.doi.org/10.3415/VCOT-15-08-0145

Volar locking plate fixation has been widely accepted method for the treatment of unstable distal radius fractures. Although the results of volar locking plate fixation are encouraging, it may cause implant-related complications such as flexor or extensor tendon injuries. In depth understanding of anatomy of the distal radius is mandatory in order to obtain adequate fixation of the fracture fragments and to avoid these complications. This article will review the anatomic characteristics of the distal radius because selecting proper implant and positioning of the plate is closely related to the volar surface anatomy of the distal radius. The number and the length of distal locking screws are also important to provide adequate fixation strength to maintain fracture fixation. We will discuss the pros and cons of the variable-angle locking plate, which was introduced in an effort to provide surgeons with more freedom for fixation. Finally, we will discuss about correcting radial length and volar tilt by using eccentric drill holes and distal locking first technique.

INTRODUCTION: In the past distal tibia fractures, including intraarticular fractures, frequently led to poor functional outcomes. The Ruedi-Allgower four steps open method, and later the Patterson and Sirkin recommendations for delayed operative treatment has made a drastic advancement in the treatment of these fractures. The two-stage minimally-invasive protocol using locking plate fixation proved a historical turning point, improving functional results to the highest levels compared to all other methods.AIM: To present the superior results of the two-stage minimally-invasive method using locking plate fixation, making this a historic step forward in treating distal tibia fractures.MATERIAL AND METHODS: A prospective longitudinal study, collecting data from Traumatology-Clinic in the 2014-2016 periods, available for nine-month follow-up. Twenty-three patients were finally included in the study.RESULTS: In analysing the data collected, we focused our attention on the final functional outcomes as indicated by dorsiflexion nine months after injury and also according to the AOFAS Ankle-Hindfoot Scale. Results were excellent with no or minimal consequences. Where complications were present, these were benign and did not require further surgery.CONCLUSION: We believe this modern method for the treatment of distal tibia fractures should be applied routinely and considered as the gold standard in this domain.

Abstract Background: Open reduction and pre-contoured locking plate fixation is a popular treatment option for displaced midshaft clavicle fracture. Lag screw and cerclage are two main intraoperative techniques to reduce and fix fragments. However, both lag screw and metallic cerclage have disadvantages. The doubled-suture Nice knot has been reported in many areas of orthopedic surgery for its effectiveness. This study aims to compare the outcomes of comminuted mid-shaft clavicle fractures reduced by Nice knots versus traditional techniques (lag screw or/and metallic cerclage) when bridged with pre-contoured locking plates.Methods: We retrospectively reviewed 101 patients (65 females and 36 males) diagnosed with midshaft clavicle fractures with at least one wedge fragment reduced by either Nice knots or traditional methods and bridged with pre-contoured locking plates between December 2016 and April 2019. Operation time, functional outcomes, pain, patient satisfaction, fracture healing and complications were assessed at a follow-up of 12 to 40 months.Results: The mean age of all the patients was 50.8 years. There were 52 and 49 patients in Nice knot group and traditional group respectively, and no differences between two groups was found in general patient characteristics, fracture type, follow up and injury-to-surgery duration. The Nice knot group had significant less operation time (p < 0.01) than the traditional group (mean and standard deviation [SD], 78.6±19.0 compared with 94.4±29.9 minutes, respectively). For healing time, functional score, pain, satisfaction and complications, there was no significant differences between groups, despite the Nice knot group had slightly better results.Conclusions: Both Nice knots and traditional methods treated for comminuted Robinson type 2B clavicle fractures were effective and safe. And the Nice knots seemed to be superior with significant less operation time.

Objective: To study the treatment outcomes of proximal femoral locking-plate fixation of pathological fractures ofthe proximal femur relative to clinical results, implant failure, and surgical complications.Materials and Methods: From 2007 to 2018, 17 patients (18 femurs) with a diagnosis of impending or existingpathological fracture of the proximal femur were treated with proximal femoral locking-plate fixation. Data collectedincluded operative duration, estimated blood loss, ambulatory status, hardware failure events, and postoperativecomplications.Results: Of the 18 femurs that were included, 13 were existing pathological fractures and 5 were impending fractures.The mean age of patients was 53.7 years (range: 28-89), and 12 of them were female. The mean follow-up was 11.3months (range: 1-67). Ten of 17 patients (62.5%) had progressive lung disease from pulmonary metastasis or fromlung primary. No patient developed oxygen desaturation or cardiac arrest during the intraoperative or postoperativeperiod. Thirteen of 17 patients (76.5%) could walk with or without an assistive device at the time of final follow-up.Two patients required close postoperative monitoring in the intensive care unit due to poor preoperative status,and both of those patients died within one month after surgery from other medical problems. No hardware failureoccurred.Conclusion: For pathological fracture of the proximal femur, proximal femoral locking-plate fixation is a treatmentoption that results in fewer perioperative and postoperative cardiopulmonary events and surgical complications.Most patients can ambulate with or without an assistive device at the final follow-up.

Background: This study aimed to identify the effect of the progression of postoperative wrist osteoarthritis on 5 years clinical and radiological outcomes after volar locking plate fixation of distal radius fractures. Methods: Altogether, 56 patients with distal radius fractures were followed up 5 years after surgery. Clinical assessment was performed using the Mayo modified wrist score, a visual analogue scale of pain, the Japanese version of the Disabilities of the Arm, Shoulder, and Hand score, and Patient-related wrist evaluation. Standardized wrist radiographs were used to assess wrist morphology and the Knirk and Jupiter’s degree of osteoarthritis. Multivariate logistic regression was used to analyze postoperative morphological changes in the wrist and carpal alignment regarding their correlation with progression of wrist osteoarthritis. Results: Progression of postoperative wrist osteoarthritis was recognized in 37 of the 56 cases (66.1%). Compared with the clinical outcomes at the time of the fracture union completion, almost clinical outcomes improved up to 5 years follow-up time as well as at 1 year after surgery. The range of wrist flexion at 5 years follow-up was significantly less in the progressive osteoarthritis group than in those with non-progressive osteoarthritis. The persistent step-off immediately after surgery significantly affected the postoperative progression of wrist osteoarthritis. Changes in the radial inclination, volar tilt, and radioscaphoid angle correlated with progression of wrist osteoarthritis. The highest correlation was with the change of radioscaphoid angle. Conclusions: Good clinical results were maintained at 5 years after surgery, but progression of postoperative wrist osteoarthritis interfered with improvement of wrist flexion. Change in the radioscaphoid angle was the factor that was most highly correlated with progression of postoperative wrist osteoarthritis.

Phalangeal Fractures

We prospectively assessed clinical and radiological outcomes of locking plate fixation in treating unstable fractures in 11 metacarpals, 15 proximal phalanges, and eight middle phalanges in 34 consecutive patients from October 2011 to December 2016. Median length of follow-up was 14 months (range 12–24). The motion of finger joints, bony union, and complication rates were recorded. The median postoperative range of motion of the two interphalangeal joints and the metacarpophalangeal joint was 82% of the contralateral hands. Fractures in the three locations had significantly different recovery of the finger motion, with the best recovery for the metacarpal fractures. Closer distance between the plate edge and joint line was associated with a more limited range of the finger motion. The clinical outcomes approached an acceptable level at final follow-up. Finger stiffness is unavoidable after locking plate fixation of metacarpal and phalangeal fractures even with early hand therapy, with stiffness occurring in 10 out of 34 cases at the time of final follow-up 1 year after surgery. Level of evidence: II

Fixation of tibial plateau fractures with plate has been widely used. This prospective study was planned to compare locking plate fixation of tibial plateau fracture with nonlocking methods in terms of their functional outcomes. The subjects of the study were selected from consecutive patients suffering from tibial plateau fractures referred to Kashani Hospital in Isfahan, Iran, between 2012 and 2013 and were candidate for surgery. The final included patients were assigned to two groups, those who were treated with locking plate (n=20) and those who were treated with nonlocking plates (N=21). The mean duration of follow-up was 13.4 months (ranging between 10 and 17 months). The mean of knee scores was significantly higher in locking plate group than in nonlocking plate group at the follow-up time (80.20±10.21 versus 72.52±14.75, P=0.039). Also, the mean VAS pain severity score was significantly lower in locking plate group compared with nonlocking plate group (4.45±2.50 versus 6.00±2.59, P=0.046). This study confirmed superiority of the locking plate method over nonlocking plate method with regard to knee score as well as VAS pain score.

Metaphyseal Comminution

Abstract Background: Volar locking plating remains a popular method for the surgical management of distal radius fractures. Dorsal metaphyseal comminution (DMC) is a common fracture pattern which weakens the stability during fracture fixation. In this study, we aimed to compare the radiographic and functional outcome of the intra- and extra-articular distal radius fractures with DMC following volar locking plate fixation.Materials and methods: Patients suffered from a distal radius fracture with DMC were reviewed in the clinical database of the authors’ institution between Jan 2016 and Jan 2020. The included patients were classified into the extra-articular (A3) group or the intra-articular (C2 and C3) group according to the AO/OTA system. The radiological parameters, wrist range of motion, and functional outcomes were evaluated following open reduction and volar locking plate fixation.Results: A total of 130 patients were included in this study with a mean follow-up length of 17.2 months. Compared with the A3 fracture group, no significant fracture re-displacement or reduced wrist ROMs was observed in the C2 fractures after 12-month’s follow-up. However, significantly decreased volar tilt (P = 0.003) as well as the extension/flexion ROMs were observed in the C3 fractures comparing to the A3 fractures. Most of the patients achieved an excellent (n = 75) or good (n = 51) Gartland and Werley wrist score. Four patients with C3 fractures resulted in a fair functional outcome due to a significant loss of volar tilt during follow-up.Conclusions: The volar locking plate fixation provided sufficient stability for distal radius fractures with DMC, and resulted in similar radiological and functional outcomes in the intra-articular distal radius fractures with a simple articular component (C2 fractures) as those in the extra-articular fractures. Considering the intra-articular fractures with multifragmentary articular component (C3 fracture), despite of the subsequent loss of volar tilt, the majority of the patients achieved good to excellent wrist function following volar locking plating.Trial registration: Not applicable because the design of the study is retrospective.
