Introduction: Intra-articular distal radial fractures in young patients occur in high energy trauma which can lead to a combination of bone and ligaments lesions. An articular step superior to 2 mm is pejorative, for that an adequate radiologic analysis is necessary accessing to the best surgical treatment. The purpose of our study was to investigate this type of fracture and expose radiologic analysis (radiograph and CT-scan) of bone and ligamentous associated lesions of this specific twisted lunate facet fracture for recognizing it and accessing to the best surgical treatment. Patients and Methods: Seven patients with severely displaced type 4 articular fractures of the distal radius whose wrists had been exposed to violent compression are reported in our series, they are required open treatment for the reduction and fixation of disrupted articular surfaces by using an antero-medial approach which allows direct access to the fragment of the lunate facet and easier visualization of the distal radio-ulnar joint. Results: All the patients were clinically examined with antero-posterior and lateral X ray, completed by a CT scan, all the fractures were type IV according to Melone classification. In all of our seven cases there was a lesion of the distal radioulnar joint (DRUJ) identified in the CT scan. The CT scan allowed us to individualize well the void of the lunate fossa and calculate his exact degree of rotation, which is very important for planning therapeutic management. Discussion: In all of our cases the CT scan was to expose all of the osseous and ligamentous injuries;in the sagittal reconstruction we were able to objectify and calculate the exact degree of the rotation of the lunate fossa fragment;in the frontal reconstruction the void of the lunate fossa is visible and in the axial reconstruction we can determine the incongruence of the distal radio-ulnar joint (DRUJ). Intra-articular involvement has long been recognized as a poor prognostic factor in fractures of the distal radius. However, despite early studies reporting poor results with non operative treatment for these injuries, most authors opposed operative intervention, due to lack of a good radiological analysis and the CT scan;knowledge that a number of studies have shown that inadequate reduction of intra-articular distal radius fractures leads to the development of arthritis. 展开更多

Tibial plateau fractures are common injuries that occur in a bimodal age distribution. While there are various treatment options for displaced tibial plateau fractures, the standard of care is open reduction and internal fixation(ORIF). In physiologically young patients with higher demand and better bone quality, ORIF is the preferred method of treating these fractures. However, future total knee arthroplasty(TKA) is a consideration in these patients as post-traumatic osteoarthritis is a common long-term complication of tibial plateau fractures. In older, lower demand patients, ORIF is potentially less favorable for a variety of reasons, namely fixation failure and the need for delayed weight bearing. In some of these patients, TKA can be considered as primary mode of treatment. This paper will review the literature surrounding TKA as both primary treatment and as a salvage measure in patients with fractures of the tibial plateau. The outcomes, complications, techniques and surgical challenges are also discussed. 展开更多

Background: Stress fractures are fatigue-induced, very small cracks in the bone caused by repetitive application of force and most often seen in the weight-bearing bones of the lower extremities of athletes or military recruits. Case Report: A 47-year-old postmenopausal and heavy smoker woman complained of localized sensitivity on the distal-anterior and medial surfaces of both tibiae, which had been ongoing for 1 month. She moved to a flat at 5th-floor without an elevator a year ago. Bilateral stress fractures were diagnosed by radiographs and confirmed by Magnetic Resonance Imaging (MRI). She was suggested to restrict activities and to use crutches until the symptoms subsided. Bilateral ankle joint pneumatic brace with full heel support was applied. The patient was followed one year after diagnosis. At the 2-month follow-up examination, the patient was pain free and planning to move to a new house. Conclusions: Several risk factors have been defined in the pathogenesis of stress fracture. In the present case, the acute phase had passed and diagnosis could be made from the direct radiographs. Although extremely rarely seen, tibia distal stress fracture should be kept in mind in the differential diagnosis of patients with the relevant risk factors who present with tibia distal localized pain. 展开更多

Background: AO type C3 distal radius fracture (DRF) is the most difficult-to-treat fracture type because of a tendency to shorten and collapse. The purpose of this study is to investigate the clinical and radiographic outcomes of comminuted intra-articular DRFs treated with a dynamic external fixator combined with a volar locking plate (VLP). Methods: Eleven patients (mean age, 61 years) with comminuted intra-articular DRFs were treated with a dynamic type of external fixator combined with a VLP. Following reduction and fixation with a VLP, the dynamic external fixator was applied and the distal ball joint of the fixator was aligned with the lunate-capitate line. The ball joint was unlocked approximately 2 weeks after surgery to allow wrist mobilization. The fixator was removed 3 - 6 weeks (mean, 5 weeks) after surgery. Consequently, clinical and radiographic assessments were carried out at the final follow-up. Results: At the final follow-up, the mean range values of wrist extension and flexion were 76&deg;and 64&deg;, respectively. Compared with the contralateral side, the mean grip strength was 84%. The mean Modified Mayo Wrist Score and the Disabilities of the Arm, Shoulder and Hand score were 88 and 9, respectively. No significant differences in the radiographic parameters exist between after surgery and final follow-up. Conclusions: This study indicated that the dynamic wrist fixator combined with a VLP is effective for the treatment of AO type C3 DRFs. 展开更多

Purpose:Distal tibia fractures comprise about 7%-10% of lower extremity trauma.Because of the peculiarity of the soft tissue and subcutaneous location of the bone there are many controversies in the ideal treatment of distal tibia fractures especially extra articular pilon fractures.Plating is fraught with complications of wound dehiscence and infection.There are limited studies which document outcomes in such cases using intramedullary interlocking nail.We intend to study the outcome and complications of extra articular distal tibial fractures treated with interlocking nailing.Methods:This is a prospective study conducted in a tertiary care orthopaedic hospital in southern India.There are 147 patients of distal tibia extra-articular fractures managed by IM nailing with follow up of more than one year were included in this study.Only cases with fresh injury (less than 1 week),fracture below the isthmus,closed and open Gustilo Anderson type 1 and 2 fractures were included in the study.Patients were reviewed at 3,6,12 and 24 weeks after surgery and thereafter at one year and were assessed for clinical and radiological signs of healing,any complications,time to union and functional outcome.Results:There were 102 males and 45 females (male/female ratio is 2.3∶1) with a mean age of 38.96 (range 23-65) years.According to AO classification,there were 78 cases (53.06%) of 43-A1,39 cases (26.53%) of 43-A2 and 30 cases of 43-A3 constituting 20.40%.The fracture united in all the patients at an average of 18 weeks (range 16-22 weeks),none of the patient in our series had a delayed or non-union.Two patients (1.47%) had the fracture united in mild valgus but it was well within the acceptable limits (<5°).The functional outcome was assessed in all the patients at final follow up using Olerud and Molander score all the patients fared an excellent to good score,there were no cases with poor score.Conclusion:Intramedullary nailing is a viable option to treat distal tibial fractures with excellent outcome.Wound complications related to plating can be avoided but meticulous surgical technique is key to avoid malunion. 展开更多

Purpose:Treatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage.There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis(MIPPO)technique and intramedullary interlocking(IMIL)nailing for extra-articular distal tibia fractures.The aim of our study is to compare the functional outcome between the two treatment methods.Methods:This was the prospective comparative study of 100 patients with distal third tibia fractures divided into two groups.The first group of patients were treated with MIPPO technique while the second group of patients were managed by IMIL nailing.Patients were followed up in outpatient department to assess the functional outcomes,malunion,delayed union,nonunion,superficial and deep infection between the two groups.Statistical analyses were performed using the SPSS software(version 16.0).Results:Average malunion(degrees)in the MIPPO group was 5(3—7)±1.41 vs.10.22(8—14)±2.04 in the IMIL group(p=0.001).Similarly postoperative knee pain in the IMIL group was 10%vs.2%in the MIPPO group(p=0.001).In terms of superficial infection and nonunion,the results were 8%vs.4%and 2%vs.6%for the MIPPO and IMIL group,respectively(p=0.001).Conclusion:Both procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue,bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing.Considering the results of the study,we have slightly more preference for the MIPPO technique. 展开更多

Objective Intra-articular fractures of the distal radius in young adults comprise a distinet fracture pattern that is diffficuh to manage and associated with a high frequency of post-traumatic arthritis.Restoration of articular congruency and alignment should improve the outcome.Methods In this study we prospectively re- viewed the results of 21 consecutive cases of dorsally displaced intra-articular distal radius fractures which were treated with internal fixation after failing to achieve articular congruency with closed reduction.Results 3 patients were lost to follow-up.For the rest of 18 patients,follow-up time ranges from 18 to 75 weeks the fractures had healed with highly satisfactory radiographic and functional results.The final volar tilt averaged 4.9°;radial inclination 23.9°;radial length 14mm;and articular incongruity,0.1 mm.Wrist motion at final follow-up examination aver- aged flexion 62°,extension 60°,radial deviation 16°,ulnar deviation 27°,pronation 77°and supination 74°.Grip strength averaged 83% of the uninjured side.The overall outcome of 18 patients(94.4%)had a good or excellent result according to the system of Gartland and Werley and 18 patients(72.2%)had a good result according to the modified system of Green and O'Brien at the most recent evaluation.The only complication in this series was a superficial pin tract infection,which was rapidly resolved with removal of pins at 5th week of external fixation. Conclusion Thus restoration of articular congruency and alignment is possible with minimal complication using modern non-angular stable methods of internal fixation. 展开更多
