SummaryAn 11 month old, female Golden Retriever was examined for chronic right thoracic limb lameness and progressive swelling of the distal radius. Survey radiographs revealed an expansile, osteolytic lesion in the distal metaphyseal region of the radius consistent with an aneurismal bone cyst. Diagnostic imaging, biopsy, angiography and histopathology supported this diagnosis. The condition was treated by segmental osteotomy of the affected radius, placement of a vascularized autogenous bone graft harvested from the contralateral ulna, and stabilized using a plate that incorporated the carpal joint. The pathogenesis, diagnostic dilemmas and treatment options in dogs and human patients is discussed.

Introduction. Giant cell tumor is a benign or locally aggressive tumor of uncertain origin that appears in mature bone, most commonly in the distal femur, proximal tibia which characteristically extends right up to the subarticular bone plate.Case Report. We report here a 35-year-old female presenting with swelling of the left knee. On examination, the swelling was solitary, about 20 × 15 cm in size with the skin over the swelling stretched and glistening. On the fifth day of hospital stay, the swelling burst open and blood tinged pus started pouring out. X-ray and MRI scan showed a well-defined T2 hyperintense expansile eccentrically located osteolytic lesion involving the metaphyseal region of the proximal tibia and extending into the subarticular space and multiple T1/T2 hypointense septations are noted within the lesion suggestive of osteoclastoma. The patient was counseled regarding the tumor and prognosis and various treatment options. She was treated successfully with above knee amputation. The tissue was sent for histopathology which confirmed osteoclastoma.Conclusion. It is important to recognize giant cell tumors early, so that they can be treated promptly with local measures to prevent morbidity and mortality in young adults.

The edentulous atrophic posterior mandible is often a great challenge for implant rehabilitation. Although a number of treatment options have been proposed, including the use of short implants and surgical grafting techniques, in cases of severe bone atrophy, techniques for mobilization of the inferior alveolar nerve (IAN) have been shown to be efficient, with good results. Four female patients underwent IAN lateralization for prosthetic rehabilitation of the posterior mandible from 2013 to 2019, with 1 year to 5 years and 4 months of follow-up. This case series describes a new technique for mobilization of the IAN, named in-block lateralization, to facilitate access to the IAN and to reduce nerve manipulation. The implant is immediately installed (allowing nerve lateralization in unitary spaces) and the original mandibular anatomy is restored with autogenous bone from the original bed during the same surgical procedure. When well indicated and well performed, this new approach provides better and easier visualization of the IAN as well as safer manipulation aiming to achieve good results for implant stability and minimal risk of neurosensory disturbances, allowing rehabilitation even in unitary spaces.

Radioulnar Joint

AbstractThe distal radioulnar joint (DRUJ), the articulation between the sigmoid notch of the radius and the distal ulna, plays a pivotal role in stability and load bearing and allows for pronation and supination of the forearm. Osteoarthritis (OA) of the DRUJ commonly occurs due to distal radius trauma but may also be the result of conditions such as joint instability, septic arthritis, or primary OA. It is initially managed with conservative therapy, but surgery is often considered when nonoperative methods fail. The surgical approaches available to treat this pathology have grown over the years. The procedures have generally favorable outcomes, each with their own unique complications and considerations. This paper comprises a review of the outcomes and complications for the different procedures commonly used to surgically treat DRUJ OA.

Aneurysmal bone cysts (ABC) are rare, benign primary bone tumors. Although benign, they can be locally aggressive resulting in erosion of bone and surrounding tissues over time. In later stages, depending on the clinical urgency, immunotherapy or surgical resection remain treatment options. This report illustrates a case of a 32-year-old female who presented with chronic worsening low back pain without neurological deficits. Radiological imaging revealed a large destructive mass arising from the thoracic spine invading into the central canal, causing critical central stenosis and cord compression. Histopathology revealed ABC. This case highlights the importance of including ABCs and other ‘benign’/locally aggressive lesions in the differential of patients with insidious musculoskeletal complaints. This case also demonstrates that one can be neurologically asymptomatic despite having critical central canal stenosis and cord compression if the causative lesion is slow growing. Understanding this allows us to arrange for most appropriate management.

Background: Distal radius fractures are one of the commonest injuries only after clavicle fractures. These fractures poses challenges to the treating surgeons as a result of which these fractures are sometime treated unacceptably and leads to poor outcome. Among various treatment options for these fractures wrist sparing Cobra external fixator is one of the options with an impressive stability and outstanding functional outcomes.Aims and Objectives: To determine whether this system can achieve adequate reduction of a variety of DRF, is able to maintain reduction despite hand and wrist movements, whether it compromises hand and wrist functions and leads to long term problems.Materials and Methods: From July 1, 2016 - June 30, 2017, all skeletally matured patients with acute distal radius fractures (AO-A2, B1, C1, C2) were adequately reduced and fixed with Cobra ex-fix. Immediately post-op patients were encouraged to start range of motion of the wrist as the pain decreased. The patients were followed up in 2,4 and 8 weeks and were analyzed clinically, radiologically, their functional outcomes and any complications.Results: Twenty-two patients were included in our study. Nine were males and 13 were females. Using the AO classification, 15 were classified as A2, 2 were B1, 3 were C1, and 2 were C2. The mean number of weeks the cobra fixator was maintained was 5.3 weeks. The Cobra ex-fix was able to achieve excellent maintenance of radial height and radial inclination and good maintenance of dorsal tilt. Recovery of functional activities according to Gartland and Werley’s functional scoring system was good to excellent in all patients at 8 weeks follow-up.Conclusion: The Cobra external fixation system is an outstanding device for use in fractures of the distal radius. It achieves superior anatomic correction and is dependable in maintaining fracture reduction even with hand and wrist use.Asian Journal of Medical Sciences Vol.9(6) 2018 84-89

Radiographic Findings

The aneurysmal bone cyst (ABC) is a benign cystic and expanding osteolytic lesion consisting of bone-filled spaces of variable size, separated by connective tissue containing trabeculae of bone or osteoid tissue and osteoclast giant cells. Radiographic findings may vary from unicystic or moth-eaten radiolucencies to extensive multilocular lesions with bilateral expansion and destruction of mandibular cortices. Treatment modalities include curettage (with reported recurrences) and resection with immediate reconstruction. The main arterial and feeder vessels may be embolized to prevent profuse intraoperative blood loss and achieve a bloodless surgical field. Failed embolization may necessitate ligation of the external carotid artery of the affected side.

Ulna Fractures

Distal ulna fractures often occur with distal radius fractures, and their treatment method is still controversial. We considered reduction of the distal radio-ulnar joint (DRUJ) surface the most important factor when treating distal ulna fractures accompanied by residual dislocation. We herein presented a patient with a distal ulna fracture accompanied by dislocation of the DRUJ surface in whom an autogenous bone fragment collected from the radius was grafted onto the ulnar bone defect after open reduction and Herbert screw fixation. In this technique, the bone fragment was supported through the medullary cavity by inserting a Herbert screw, which was less likely to cause irritation between the screw and surrounding tissue, because the screw was almost entirely present in the bone. In addition, an autogenous bone graft from the same surgical field may be less invasive than that from another region.
