Chondrosarcoma of the proximal radius treated by wide resection and reconstructed by 3D printed implant: A case report and description of surgical technique

The prevalence of dentoalveolar injuries in children is approximately 25%, with falls from own height being one of the main etiologies. Diagnosis is based on the clinical evaluation associated with complementary imaging tests. The treatment of choice depends on the type of damage and structure affected. For alveolar process fractures, closed reduction and semi-rigid dental splinting for 4 to 6 weeks is generally satisfactory. However, some cases, such as severe segmental fractures, require open treatment to ensure adequate reduction and stabilization of the displaced alveolar segment, which is usually achieved by titanium miniplates and screws. Nevertheless, there are situations where this type of fixation is not possible, requiring alternative methods. Therefore, this article describes a surgical technique performed by open reduction, associating semi-rigid dental splint and circummandibular wiring in pediatric patient diagnosed with dentoalveolar fracture through clinical examination (with bone fracture displacement) and tomography. The technique promoted a good prognostic to the patient, proving to be a viable alternative for treating dentoalveolar fractures.

Uncommon Condition

Congenital bilateral humeroradial synostosis (HRS) is a rare condition. It is generally divided into 2 categories. In the first group, which is mainly sporadic, additional upper limb hypoplasia typically coexists. In the second group, which is classically familial, HRS is commonly an isolated upper extremity anomaly. HRS can lead to variable degrees of functional disability. The clinical case reported here illustrates a possibly avoidable presentation of this uncommon condition. In this case report, we present a 6-week-old male who presented with bilateral radius fractures. Radiography revealed congenital HRS at both elbows. No other associated congenital abnormalities were detected, and there was no family history of similar conditions in any first-degree relatives. In cases of congenital HRS, movement at the elbow joint is not possible. Parents who are unaware of this information might try to straighten their infant’s elbows, which in turn may result in fractures of the proximal radius. Hence, early diagnosis and proper parental education could prevent fractures as a sequela of HRS.

Object The aim of this study was to describe the surgical technique used for removal of sphenoorbital meningiomas in the authors' practice and to review the operative outcome. Methods Review of the senior author's practice between 1994 and 2009 revealed 39 patients (mean age 48 years) eligible for this study. Clinical presentation, surgical technique, postoperative outcome, and follow-up data are presented. Surgical technique is detailed, with an emphasis on aggressive removal consisting of drilling of the hypertrophied sphenoid bone, orbital wall, and anterior clinoid process, followed by tumor removal and a wide resection of the involved dura. A simple dural closure without reconstruction of the orbital roof or the lateral wall of the orbit is also described. Results Gross-total resection was achieved in 15 cases (38.5%), near-total resection with small residual in the cavernous sinus or periorbita in 20 cases (51.3%), and subtotal resection in 4 cases (10.3%). Postoperative complications included trigeminal hypesthesia in 9 patients, oculomotor palsy in 3 patients, and seizure in 2 patients. Seven patients had recurrence within the mean follow-up period of 40.7 months. Preoperative visual deficits were present in 21 patients (53.8%). Of these, 14 (66.7%) experienced visual recovery to normal levels postoperatively. Statistical analyses revealed preoperative severe visual deficit and sphenoid bone hypertrophy as an independent risk factor and an independent favorable factor, respectively, for a favorable visual outcome. Proptosis was resolved (≤ 2 mm) in 73.5% of the authors' patients. No patient had postoperative enophthalmos. Conclusions In the authors' practice, surgery for sphenoorbital meningiomas consists of resection of the orbital/sphenoid intraosseous, intraorbital, and intradural tumor components. The authors believe that aggressive removal of the orbital/sphenoid intraosseous tumor is critical for a favorable visual outcome and tumor control. Furthermore, satisfactory cosmetic results can be achieved with simple reconstruction techniques as described.

Talar Body Fracture

The talus is the second most common fractured tarsal bone. While their incidence may be low, talus fractures are severe injuries that can lead to long-term disability and pain. Displaced talar body fractures are typically treated through an open approach with the aim of obtaining anatomic reduction and stable fixation. There are several case reports in the literature demonstrating successful management of talus fractures arthroscopically. An arthroscopic approach minimizes soft tissue trauma, which can help decrease postoperative wound complications and infections. In this article, the authors describe a surgical technique of an arthroscopic reduction and internal fixation of a comminuted posterior talar body fracture. Compared with an open posterior approach with or without osteotomies, an arthroscopic technique improved visualization and allowed precise reduction and fixation.
