Abstract:

Introduction: Fractures of the lumbar spine and thoracolumbar junction are common in spinal trauma. The aim of this work is to analyze the nature of the indications, the morbidity as well as the results of these treatment regimens. Patients and Methods: A retrospective, single-center study, based on a review of 64 patients with lumbar spine and thoracolumbar junction fractures (T10-L2) without neurological disorders, was collected in the neurosurgery department of the North Hospital and University Hospital (CHU), Marseille over a period of 2 years from January 2015 to December 2016. Posterior percutaneous osteosynthesis were more or less associated with kyphoplasty preceded anterior arthrodesis. Clinical and radiological endpoints were collected at least 6 months later. Results: The mean follow-up was 9.5 months (6 - 24). The clinical evaluation found a mean VAS at last follow-up at 14/100 (0 - 30) and an average Oswestry score at the last follow-up at 88%. The initial average vertebral kyphosis went from 13° to 4° at the last follow-up with a correction loss of 1°, an absolute gain of 8°. No postoperative neurological complications were noted in our series. Conclusion: The implementation of a two-step therapeutic strategy with anterior reconstruction in Magerl’s lumbar spine or A3.3 thoracolumbar junction fractures allows effective and long-lasting correction of lumbar lordosis and thoracic kyphosis, and obtaining a balanced spine in the sagittal plane. Our functional results are close to normal, with low morbidity and a low complication rate.

Tibiotalar arthrodesis for injuries of the talus
Singh Jaswant
Indian Journal of Orthopaedics , 2008,
Abstract: Background: Fracture-dislocation of the talus is one of the most severe injuries of the ankle. Opinion varies widely as to the proper treatment of this injury. Since Blair′s original description of the tibiotalar fusion in 1943, there is little mention in the literature of his method. The present study reports the results of tibiotalar arthrodesis with modification in Blair′s technique. Materials and Methods: Eleven cases of modified Blair ′ s tibiotalar arthrodesis were retrospectively studied. The average age was 32.4 years (range, 26-51 years). Six patients had posttraumatic avascular necrosis; five had neglected fracture-dislocation of the talus. Results: The mean followup is 8 years (range 3-12 years). Tibiotalar fusion was achieved in all the ankles at an average of 20.5 weeks (range 16-28 weeks). Nine cases having 15°-20° tibiopedal motion had excellent results and two ankles having 10°-15° of tibiopedal motion had good result. Conclusion: We achieved good long term results with tibiotalar arthrodesis with modification in Blair technique. The principal modification in the present study is retention of the talar body while performing arthrodesis with anterior sliding graft. The retention of the talar body provides intraoperative stability and in the long term, the retained talar body shares the load transmitted to the anterior and middle subtalar joints thus resulting in improved hind foot function and gait.

Abstract:

Introduction: Proximal tibiofibular joint osteoarthritis is a rare disease most commonly occurring in the presence of either systemic inflammatory conditions or severe knee osteoarthritis. Case Presentation: The authors present a case report of isolated bilateral tibiofibular arthrosis in an otherwise healthy 28-year-old female patient. The patient presented with complaints of lateral knee pain. Radiographs and magnetic resonance imaging (MRI) revealed bilateral tibiofibular joint osteoarthritis. Trauma, repetitive use injury, and rheumatologic causes were excluded. The patient’s pain was initially managed conservatively, but she subsequently underwent tibiofibular arthrodesis for progressive pain symptoms. We review in this report the current literature on tibiofibular joint osteoarthritis and its treatment. Conclusion: Isolated tibiofibular joint osteoarthritis is a rare condition that may progress and requires surgical treatment to achieve optimal clinical outcomes.

Abstract: the functional results of 51 wrist arthrodesis carried out in 49 patients with different regional pathologies are analyzed. in all cases the arthrodesis was performed with rigid internal fixation with a dynamic compression plate; postoperative follow-up ranged from 6 to 201 months (average: 73 months). both subjective and objective methods were used in the evaluation. the subjective method was based on the evaluation by the patients and the objective method on analysis of radiographs and functional tests simulating all different functions of the upper limb. the arthrodesis was performed in 14o extension and 8o ulnal deviation, on average. primary healing was obtained in 50 wrists (98%) in eight weeks on average. pseudarthrosis was observed in one single case, and eventually healed after reoperation for bone grafting. all patients presented pain improvement, with a different pattern, as compared to the preoperative period and all of those with lighter activities resumed their previous occupation. relative loss of grip strength (61% from normal) and digital pinch (70% from normal) were observed, but final results were considered as satisfactory on the functional tests, in accordance to the literature. it was concluded that wrist arthrodesis is applicable to a diversity of wrist pathologies which imply in pain and unstability, with easily reproducible results, without significantly affecting the global upper limb function, despite the relative loss of power, mainly due to the pre-existing factor.

Abstract: spinal lumbar stenosis is a disease that occurs mainly between the 5th and 7th decade of life and can be congenital or acquired. the latter has many etiologies, but a degenerative cause is the most common. stenosis is a narrowing of the spinal canal diameter caused by many factors such as bulging discs, hypertrophy of flavum ligament, facet capsule thickening and osteophyte formation. the classical symptom of the disease is sciatic pain, that improves with lumbar flexion and worsens with ambulation. neurological examination is often normal and the most useful imaging test is magnetic resonance imaging (mri). conservative management consists in non-steroidal anti-inflammatory drugs, muscle relaxants, physical therapy and epidural - radicular infiltrations. spinal infiltrations have a proven efficacy for pain management. a good result of this therapy predicts a favorable outcome after surgery. surgical treatment consists in decompression with or without lumbar fusion. the addition of an arthrodesis is recommended for degenerative spondylolisthesis, correction of deformities, recurrent spinal stenosis with instability, sagittal or coronal imbalance and adjacent segment disease.

Abstract: when knee bony tumors appear, arthrodesis is one terapeutic option after tumor block resection. the implant is composed of an intramedular nail with four interlocking pins. the whole implant is manufactured using a titanium alloy (ti-6al-4v). the spacer has the capability of be extended from 20 cm up to 30 cm, and it is used as a definitively treatment. the use of this item reports good result despite the fact that affected limb is arthrodesed. however, it has a great interest to study the influence of bone tumor resection size on the implant integrity. to perform this research work, we developed a finite element model of the complex femur-implant-tibia, by means of ansys software version 11 (ansys, inc). the loading conditions used during modeling process correspond to those occurring during midstance phase of gait. we analyzed six cases, varying spacer length: 20 cm, 22 cm, 24 cm, 26 cm, 28 cm and 30 cm. our results indicate that there is no fracture failure risk within the implant when varying spacer length over the range previously stated, since we did not find significative difference on stress levels within the implant. however, stress levels of inter locking tibial pins are increased considerably for a resection of 24 cm or higher, this fact could lead us to implant loosening.

Abstract: Depending upon initial treatment, between 2 and 30% of patients with a displaced intra-articular calcaneal fracture require a secondary arthrodesis. The aim of this study was to investigate the effect of subtalar versus triple arthrodesis on functional outcome. A total of 33 patients with 37 secondary arthrodeses (17 subtalar and 20 triple) with a median follow-up of 116 months were asked to complete questionnaires regarding disease-specific functional outcome (Maryland Foot Score, MFS), quality of life (SF-36) and overall satisfaction with the treatment (Visual Analogue Scale, VAS). Patient groups were comparable considering median age at fracture, initial treatment (conservative or operative), time to arthrodesis, median follow-up, and post-arthrodesis radiographic angles. The MFS score was similar after subtalar versus triple arthrodesis (59 vs. 56 points; P = 0.79). No statistically significant difference was found for the SF-36 (84 vs. 83 points; P = 0.67) and the VAS (5 vs. 6; P = 0.21). Smoking was statistically significantly associated with a non-union (χ2 = 6.60, P = 0.017). The current study suggests that there is no significant difference in functional outcome between an in situ subtalar or triple arthrodesis as a salvage technique for symptomatic arthrosis after an intra-articular calcaneal fracture. Smoking is a risk factor for non-union.

Strategies in Trauma and Limb Reconstruction , 2007, DOI: 10.1007/s11751-007-0018-4
Abstract: A retrograde nail with posterior-to-anterior (PA) locking into os calcis, talus and tibia was used to correct deformity and achieve fusion after failed fusion. A variety of methods have been published to achieve union of the ankle and subtalar joint in a failed fusion situation. We have studied a retrograde locking nail technique through a 2.5-cm incision in the non-weightbearing part of the sole of the foot. Remaining cartilage in the ankle joint, where necessary, was percutaneously removed through an anterior approach and the locking nail was inserted after reaming of os calcis, talus and tibia. Locking screw insertion was in the sagittal plane (p.a. direction), in talus os calcis and tibial diaphysis using a nail mounted jig. Ten patients were entered in the study (age 27-60 years). The initial aetiology for attempted fusion was post-traumatic in nine cases and rheumatic in one case. There were 25 previous operations in the cohort not leading to fusion. An additional temporary external fixator was used in four cases to reach and maintain the optimum position for the procedure. The intervention time was 30-75 min. Dynamisation of the nail was performed after four months under local anaesthesia. The mean duration of follow-up was 4 years (3-5.5 years). Radiologically and clinically, fusion was achieved in 16 weeks (range, 12-20 weeks). There was no loosening of the implant or implant failure. A leg length discrepancy was avoided using this technique. There was one complication with varus malunion in a heavy smoker which united after corrective osteotomy, revision nailing and bone grafting. Patient satisfaction was measured on a scale (not visual analogue) of 0 (not satisfied) to 10 (completely satisfied); overall satisfaction averaged 9.5 points (range, 6-10 points). The postoperative ankle-hindfoot score of the American Orthopedic Foot and Ankle Society averaged 73.5 points (range, 61-81 points). Retrograde locked nailing with locking in the sagittal plane is a reliable minimally invasive procedure to achieve fusion of the ankle and the subtalar joint after failed fusion.

Abstract: Background: The best method of treating intractable hip pain in an unsalvageable hip joint in a child is still a subject open to debate. We believe that hip arthrodesis in such patients provides a painless and stable hip for most activities of daily living in our challenging rural terrain. Therefore, we conducted this study to assess the functional ability of children with painful hip arthrosis treated by arthrodesis of the hip. Materials and Methods: A retrospective evaluation of 28 children (out of 35) who had an arthrodesis of the hip performed between 1994 and 2008 was carried out. The average age was 14 years, with 12 males and 16 females. There was involvement of the right hip in 13 and left in 15 cases. The average duration of follow-up was 4.87 years. The preferred position of the hip for arthrodesis was 20-30° of flexion, neutral abduction-adduction, and neutral rotation, irrespective of the method of fixation. Results: The average duration of clinical and radiological arthrodesis was found to be 4 months (2-6 months). At the last follow-up, all patients were painfree and had good ambulatory capacity. The average Modified Harris Hip Score increased from 53 to 84 and the average post-surgical limb length discrepancy was 1.3 cm, which was well tolerated in all cases. Patients, however, had difficulty in squatting and had to modify their posture for foot care, putting on shoes, etc. Also, some patients complained of ipsilateral knee, contralateral hip, or low back pain with prolonged activity, but this was not severe enough to restrict activity except in one case that was known to have juvenile rheumatoid arthritis and needed ambulatory aid. Conclusion: In an environment where pathology generally presents very late and often in a dramatic manner, where the patient′s socioeconomic status, understanding, compliance, and the logistics of follow-up are consistently a challenge in management, hip arthrodesis has been an important procedure for our patient group, with good short-term results and promising midterm, and, hopefully, long-term prospects. In our series of patients, we have been successful in restoring painfree mobility.
