Osteochondral flap fracture of the coronoid in pediatric elbow dislocation: a case report and literature review.

Osteochondral flap fractures of the coronoid are rare occult fractures, often diagnosed in delay, in pediatric patients who underwent elbow dislocations. Only 11 pediatric cases of osteochondral flap fractures of the coronoid are described in the literature. We describe a pediatric case treated in our institution for an elbow dislocation accompanied by a triad of elbow fractures, including the osteochondral flap fracture of the coronoid, and review available literature on the osteochondral flap fracture of the coronoid in pediatric patients.

Treatment of paediatric unstable displaced distal radius fractures using Kapandji technique: a case series.

BACKGROUND: The technique of intra-focal pinning described by Kapandji is seldom used in paediatric patients. We present our series of paediatric patients treated with Kapandji technique for unstable displaced distal radius fractures. METHODS: We retrospectively reviewed medical records and radiographs of a consecutive series of 56 paediatric patients who underwent closed reduction and fixation with Kapandji technique for unstable displaced metaphyseal and Salter Harris 2 distal radius fractures, from 2008 to March 2018. One or two percutaneous K-wires were inserted intra-focally without crossing the physis to lever out, reduce and stabilize the distal fragment. The arm was immobilized with an above-elbow cast, and radiographic controls were scheduled at 1, 4, 8 weeks, at least. RESULTS: The mean age at the time of the trauma was 10.5 years. The K-wires were removed at a mean of 6.4 post-operative weeks. An above-elbow cast was used for the first 4 weeks, afterwards a below-elbow cast for 2 weeks and a short-arm brace until the full recovery of motion. The mean follow-up was 18 months (range 1.5-108 months). No pin-related complications were found. All fractures showed good healing, and the full function of the wrist was achieved in every case. CONCLUSION: Kapandji pinning is a reliable technique in paediatric patients with unstable displaced distal radius fractures. It shows a lower complication rate compared to other techniques. For these reasons, we suggest implementing its use in clinical practice.

Pediatric Posterior Cruciate Ligament Avulsion Fracture of the Tibial Insertion: Case Report and Review of the Literature.

Background Posterior cruciate ligament (PCL) avulsion fracture of the tibial insertion is a very rare injury in children. In addition to performing an attentive clinical examination, radiologic studies are fundamental for its correct diagnosis and treatment. Its management may be either conservative or operative. So far, only a few cases treated conservatively have been reported in the pediatric population, with controversial results. Methods We prospectively collected and reviewed clinical and radiographic data of an 11-year-old boy with avulsion fracture of the tibial insertion of the PCL. In addition, we performed a systematic review of the literature available to date. Results We decided to treat the avulsion fracture in a conservative way. The patient has been followed with accurate clinical and radiological follow-up controls until complete recovery. Conclusion Posterior cruciate avulsion fracture is a very rare finding in children, and no definitive indications for its appropriate management exist. With this report, we demonstrate that these fractures can be treated conservatively in selected cases with good results, avoiding potential surgical-related complications. Study Design This is a case report (level of evidence V).
