  • Tension Band Wiring Is As Effective As a Compression Screw in a Neglected, Medial Maleolus Non-Union
    Case Report Journal of Orthopaedic Case Reports 2017 Jul-Aug: 7(4):Page 72-75 Tension Band Wiring Is As Effective As A Compression Screw In A Neglected, Medial Maleolus Non-Union: A Case-Based Discussion & Literature Review Rakesh John¹, Mandeep Singh Dhillon¹, Ankit Khurana², Sameer Aggarwal¹, Prasoon Kumar¹ Learning Points for this Article: Compression screw fixation has been the workhorse implant for medial malleolar nonunions; however, tension band wiring may be a better technique for such nonunions, as seen in this rare case of isolated, medial malleolus gap nonunion. Abstract Introduction: Isolated, neglected medial malleolus nonunion cases are a rare entity in orthopedic literature. All studies (except one) have described the use of compression screws (with or without plates) for medial malleolar nonunion management. In acute fractures, tension band wiring (TBW) has shown excellent results both in biomechanical and in clinical studies. On the contrary, it has seldom been used in nonunion or in neglected cases. Case Report: We describe a 6-month-old neglected medial malleolus gap nonunion case who presented with progressive pain and limp. TBW with a monoblock, inlay, tricortical, and iliac crest bone graft for the defect was performed. The fracture united within 12 weeks and patient went back to his normal work routine; on the latest follow-up at 3 years, the patient was asymptomatic with no clinicoradiologic signs of secondary osteoarthritis of the ankle joint. Conclusion: TBW may be better than screw fixation in the management of medial malleolus nonunion as it is technically straightforward and cost-effective, can provide equal or more compression than a screw; it does not damage the sandwiched inlay bone graft, and the amount of compression is surgeon-controlled.

Tension band wiring with cerclage wiring is most widely used for treating displaced patellar fractures. Although wire breakage is not uncommon, migration of a fragment of the broken wire is rare, especially migration into the knee joint. We describe here a rare case of migration of a wire fragment into the posterior septum of the knee joint after fixation of a displaced patellar fracture with tension band wiring and cerclage wiring. Although it was difficult to determine whether the wire fragment was located within or outside the knee joint from the preoperative plain radiographs or three-dimensional computed tomography (3D CT), we found it arthroscopically through the posterior transseptal portal with assistance of intraoperative fluoroscopy. Surgeons who treat such cases should bear in mind the possibility that wire could be embedded in the posterior septum of the knee joint.

Email: [email protected] ABSTRACT Background: Tension Band Wire(TBW) fixation of olecranon fracture is a commonly used technique by orthopaedic surgeons. However surgeons do not strictly adhere to the AO standard. Objectives: To determine the use and variability of this technique by surgeons at the hospital. Design: A hospital based retrospective study using anonymous radiological records. Setting: North Staffordshire University Hospital in United Kingdom. Materials and Methods: Computer software was used to retrieve, review and measure pre and postoperative radiographs of olecranon fracture cases. All identifying information was electronically masked. Results: The mean age was 50.1 years with a median of 56 years. 16.9% were open fractures. Fifty percent of the TBW met the AO standard.

Internal fixation Hypothesis: Unstable os acromiale is the cause of atypical scapulalgias. Stabilization by tension band wiring and an embedded slot shaped graft achieves union and relieves pain. Patients et methods: This series includes 10 patients mean age 43 years old presenting with shoulder pain resistant to a mean 15 months of conservative treatment. Pain followed trauma in three cases. Three patients had a history of acromioplasty, which had not relieved pain. All had pain during palpation of the superior aspect of the acromion. The diagnosis was confirmed in eight patients by positive results to local injection of the os acromiale. The mean preop- erative Constant score was 53.4. The procedure included open reduction and fixation of the acromion by tension band wiring and pinning associated with an embedded iliac crest graft without acromioplasty. Results: The mean follow-up was 48 months. Pain was relieved in seven cases and all patients had improved and were satisfied.

Most of these injuries are low energy, rotational injuries. Many modalities of treatment are present, including non-operative or operative treatment to restore normal anatomical alignment and to resume normal fictional ability of the ankle. Aim of study: To determine the outcome of surgical treatment of the medial malleolar fractures by tension band wiring versus screws fixation techniques. Patients and Methods: Randomized controlled trial conducted to study two groups of patients at Department of Orthopedic surgery in Al- Hussain medical city teaching hospital from July 2017 to July 2020, to evaluate the outcome of 36 patients with closed displaced horizontal oblique medial malleolar fractures. All the patients admitted to the emergency department of the hospital and operated within 24 hours. The study is based on 36 patients including males and females having closed displaced medial malleolar fractures of skeletally mature patients, divided in to two groups; group (A) managed by tension band wiring and group (B) with screws fixation, and followed for a maximum period of 20 weeks looking for union rate, infection, loss of reduction and the reoperation rate.

To optimize surgical results, however, these procedures should be applied to carefully selected patients. Objectives: To determine the clinical, neurodiagnostic, appropriate posterior cervical approaches to be employed in patients presenting with MR- and CT-documented multilevel cervical disease. To limit perioperative morbidity, dorsal decompressions with or without fusions should be performed utilizing awake intubation and positioning and continuous intraoperative somatosensory- evoked potential monitoring. Setting: United States of America. Methods: The clinical, neurodiagnostic, and varied dorsal decompressive techniques employed to address pathology are reviewed. Techniques, including laminectomy, laminoforaminotomy, and laminoplasty are described. Where preoperative dynamic X-rays document instability, simultaneous fusions employing wiring or lateral mass plate/screw or rod/screw techniques may be employed. Nevertheless, careful patient selection remains one of the most critical factors to operative success as older individuals with prohibitive comorbidities or fixed long-term neurological deficits should not undergo these procedures. Results: Short- and long-term outcomes following dorsal decompressions with or without fusions vary. Those with myelopathy over 65 years of age often do well in the short-term, but demonstrate greater long-term deterioration.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Fractures of the proximal tibial epiphysis are rare, representing less than 3% of all epiphyseal and 1% of all physeal injuries in adolescents. Bilateral injuries are extremely rare. The specific anatomical and histological features of the proximal tibial epiphysis make it vulnerable to a specific fracture pattern that occurs when the tensile force of the quadriceps is greater than the fibrocartilaginous tissue underlying the tibial tuberosity. We report the first case to our knowledge of a 12-year-old boy who sustained simultaneous bilateral tibial avulsion fractures on the background of a previous conservatively managed unilateral tibial tuberosity avulsion fracture. We report this case for its uniqueness and as an educational review of the anatomy, the mechanism of injury, and the development of classifying these fractures and discussion of the stages of the growing physis that determine the treatment approach.
