  • Purpose: The purpose of this study was to evaluate the radiologic outcomes of distal fibular fractures and to analyze the risk factors associated with nonunion. Materials and Methods: Between January 2009 and March 2016, 13 patients who had final nonunion with ankle fracture were included. In the control group, 370 patients who had undergone bony union and removed metal implants were included. All patients underwent the same surgical procedure and had the same treatment method, ultimately achieving satisfactory open reduction results with less than 2 mm fracture gap. Surgical treatment of fracture was considered to have the same effect on nonunion, and factors that might be associated with nonunion were evaluated. SPSS ver. 13.0 (SPSS Inc., USA) was used for all statistical analyses. Pearson's chi-square test and multi-variate regression analysis were performed to determine the factors affecting nonunion of distal fibular fracture. A p-value less than 0.05 was considered statistically significant, and relative risk was assessed. Results: The mean age of 13 patients was 46.9 years (range, 16~57 years); there were 8 men and 5 women. Among the 13 patients with nonunion, atrophic was the most common (12 cases). The association between the injury mechanism and the Lauge-Hansen classification and diabetes mellitus was not statistically significant. Distal fibular fractures with tibia shaft fracture (p=0.015) and Danis-Weber type C fracture (p=0.023), open fracture (p=0.011), and smoking (p=0.023) were significantly associated with nonunion. Conclusion: In this study, the combined injury of the ipsilateral tibia shaft fracture, open fracture, and Danis-Weber type C fracture may increase the possibility of nonunion. Therefore, caution is advised to prevent nonunion.

  • The nonunion means a state that the healing of fracture has stopped, and the part of fracture remains to not heal up in several months. The medical treatment of nonunion was tried several way to add stability to fracture. The treatment of The electrical stimulation and medicine which is make from calcium, phosphorus, and Vitamin A, D have used, but recently try to use Ultrasound and Laser in the physical therapy. In the text, we look into definition of nonunion, a cause, fracture of treatment process and approach of nonunion treatment. So, using Ultrasound and Laser in the physical therapy can be great help to the fracture and nonunion

  • Purpose: Nonunion of intra-articular fractures of calcaneus is rarely reported complication. We present our experiences with 4 patients (5 cases) treated operatively for nonunion after intra-articular fracture of calcaneus. Materials and Methods: 4 patients (5 cases) with nonunion of intra-articular fracture of calcaneus after operative treatment were followed for 4 years (from 2002 to 2006). For assessment, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Visual Analogue Scale (VAS) were assessed for clinical outcome and the union of fracture site, the talocalcaneal height and the angle of talar declination were determined for radiologic outcome. Results: The mean talocalcaneal height was 6.94 cm (range, 5.9${\sim}$7.6 cm) preoperatively and 7.34 cm (range, 6.0${\sim}$8.3 cm) at last follow-up. The mean angle of talar declination was 5.68 degrees (range, 4.6${\sim}$8 degrees) preoperatively and 13.1 degrees (range, 5.7${\sim}$21 degrees) at last follow-up. The mean preoperative AOFAS score and VAS were 20.4 (range, 14${\sim}$36) and 4 (range, 3${\sim}$6), respectively. At last follow-up, these scores improved to a mean of 59.6 (range, 54${\sim}$68) and 3 (range, 2${\sim}$4), respectively. Unions of previous nonunion site of intra-articular fracture of calcaneus were achieved in all 4 patients (5 cases). Conclusion: The reconstructive procedure for nonunion of intra-articular fracture of calcaneus showed good results in terms of bone union, radiologic results and functional improvement than preoperative state. Because the plantar pain for the inferior angular formation in nonunion site may happen, we will pay attention to reduction of fragment.

  • Failure to use effective methods of reduction, fixation, and immobilization may lead to nonunion with osteomyelitis, owing to the compound nature of most fractures of the mandible. Nonunion results in fibrous pseudoarthrosis at the fracture site with instability that, once formed, does not improve spontaneously. Once the nonunion with osteomyelitis secondary to fractures has become established, intermaxillary fixation and drainage of infected tissue should be instituted as early as possible, because the fixation & drainage enhances the patient comfort and hinders ingress of microorganisms & debris by movement of bone fragments. The authors treated three cases of nonunion with osteomyelitis by intermaxillary fixation, incision & persistent drainage on the previous fistula site and endodontic drainage of infected teeth in the fracture site of mandible. The localization & sequestration of the infected bone around the fracture was better performed persistently by natural homeostatic mechanism in $8{\sim}10$ weeks and the bony union was then attained without bone grafting.

  • A 6-year-old male mongrel dog with a 7-month history of ulnar-radial nonunion fracture was treated with implantation of recombinant human bone morphogenetic protein-2 (rhBMP-2). The dog had received surgical correction three times prior to the admission but radiography of the affected limb revealed a typical figure of nonunion fracture. Glossly, the fractured ends were sclerotic and the area between the ends was filled with fibrous tissue. After debridement the shaft was fixed by an 10-hole plate. rhBMP-2 at a total dose of 256 micrograms was implanted with a synthetic carrier into the 10-mm defect formed by the debridement. Callus formation responding to rhBMP-2 was radiographically observed at 4 weeks after implantation and the defect bridged both fracture ends by 8 weeks after implantation. The plate was removed at 12 months after implantation. Any complications were not observed for 5 months after removal of the plate.

  • The proper management of mandibular fractures involves reduction, rigid fixation, and immobilization to allow bone healing. Nonunion or malunion at the fractured sites is a well-known complication of fracture when the treatments are inappropriate. We present a case of left mandibular fracture due to shrapnel during the Korean War. The patients did not receive appropriate treatment at that time, so nonunion and malunion developed. Sixty years after the accident, mandibular osteomyelitis on the fracture site developed due to dental-origin inflammation. The treatment was based on relatively conservative care, such as saucerization and administration of antibiotics. There was no complication during the short-term follow-up. We present the case with literature review.

  • Purpose: Due to recent advances in internal fixation techniques, instrumentation and orthopedic implants there is an increasing number of humeral shaft fracture treated operatively. As a consequence, an increased number nonunion after operative fixation are being referred to our center. The aim of this study is to report the common error during osteosynthesis that may have led to nonunion and present a systematic analytical approach for the management of aseptic humeral shaft nonunion. Methods: In between January 2007 to December 2013, 20 patients with humeral shaft nonunion after operative procedure were treated according to our treatment algorithm. We could analysis x-rays of 12 patients from initial treatment to nonunion. In a subgroup of 12 patients the initial operative procedure were analyzed to determine the error that may have caused nonunion. The following questions were used to examine the cases: 1) Was the fracture biology preserved during the procedure? 2) Does the implant construct have enough stability to allow fracture healing? Results: In 19 out of 20 patients have showed radiographic evidence of union on follow up. One patient has to undergo reoperation because of the technical error with bone graft placement but eventually healed. There were 2 cases wherein the treatment algorithm was not followed. All patients had problems with mechanical stability, and in 13 patients had biologic problems. In the analysis of the initial operative fixation, only one of 12 patients had biologic problems. Conclusion: In our analysis, the common preventable error made during operative fixation of humeral shaft fracture is failure to provide adequate stability for bony union to occur. And with these cases we have demonstrated a systematic analytic management approach that may be used to prevent surgeons from reproducing the same fault and reduce the need for bone grafting.

  • Purpose: The distal clavicle has a biomechanical structure different from that of the proximal or middle 1/3 clavicle, and delayed union or nonunion occurs frequently in a distal clavicle fracture. The authors obtained favorable results from an open reduction and bone grafting of the distal clavicle nonunion. We report the results together with review of the relevant literature. Materials and Methods: The subjects were 8 patients(average age, 38.9) who had undergone surgery for distal clavicle nonunion from August 2003 to May 2006. Nonunion occurred after surgical treatment in 4 cases, and after conservative treatment in the other 4. In all cases, the patients complained of pain. Results: The mean follow-up duration was 14 months, and radiological union was observed in 8 weeks on average. In all cases, the range of shoulder joint motion was normal at the end of the follow-up observation. In the functional evaluation, 7 cases showed excellent results and 1 case showed good results. Conclusion: Surgical treatment is a safe and reliable treatment for distal clavicle fracture nonunion because it can achieve early rehabilitation and union.

  • Fractures of the clavicles are extremely common, accounting for 5 to 10% of all injuries in the adult skeletal trauma. Despite this, nonunions and symptomatic malunions after clavicular fracture are uncommon. When these complications occur, however, they may be associated with 11 pattern of disability that includes not only pain but also impairment of upper extremity function. The purpose of this study was to clarify the outcome of clavicular fractures treated by conservatively, and emphasize treatment and factors that possibly predispose a clavicular fracture to poor function or nonunion. We evaluated 9] consecutive fractures of the middle-third of the clavicle in adults which had been treated conservatively. There were 59 males and 33 females ranging in age from 17 to 80 years (average 36.8 years). Nine of the 91 fractures (10%) had developed nonunion, and 4 fractures (4.4%) reported unsatisfactory results. No patients had significant impairment of range of motion or strength as a result of the injury. We found that initial shortening at the fracture of≥20mm(6 cases) had a highly significantly association with nonunion(P<0.0001). Final shortening of 20mm or more (4 cases) was associated with an unsatisfactory result, but not with nonunion(P<0.0001). Our results have led us to recommend the open reduction and internal fixation of severely displaced fractures of the middle third of the clavicle in adults patients.

  • A 13-year-old, 4.2 kg female poodle was referred for failure of first bilateral mandibular surgery at a local animal hospital after pathologic fracture. Surgery was performed with 2.0-mm miniplates/screws and porcine cancellous bone grafts. In addition, because of the large size of the right segmental defect, a barrier absorbable membrane was employed for guide bone regeneration on right mandible. After surgery, follow-ups performed at 1 day, 1, 4, 8, and 12 weeks; there were no signs of dental malocclusion, nonunion or soft tissue infection. However, a 1-year long-term follow-up showed nonunion in the left mandibular fracture site for which a collagen membrane had not been used. It is considered that use of porcine bone graft with barrier absorbable membrane may be effective for the repair of mandibular nonunion in a geriatric dog.
