The purpose of the present study was to evaluate the postoperative radiographic and functional outcomes of reduction and fixation of a posterior plafond fracture using a posterolateral approach. We included 38 patients with a tibial plafond fracture. Fixation was most commonly performed using screws, T plates, or meta plates. ⋯ One patient (3.1%) developed symptomatic post-traumatic arthritis. The posterolateral approach allowed for good exposure and buttress fixation of the posterior plafond fractures with few local complications. The anatomic repositioning and stable fixation resulted in good functional and subjective outcomes.

Distal tibiofibular syndesmosis injury accounts for 1% to 11% of soft tissue injuries of the ankle. Some acute syndesmotic injuries will fail to heal effectively owing to inadequate treatment or misdiagnosis, eventually resulting in chronic instability, which can destroy the stability of the ankle joint. Various surgical techniques have been described for fixation of the syndesmosis. ⋯ However, the "relatively" long suture between buttons can gradually relax under continuous loading, resulting in fixation failure, which we have termed electric wire phenomenon. In the present report, we have described a modified technique for flexible fixation using the Endobutton CL ULTRA fixation device by tricortical fixation, instead of quadricortical fixation, to allow for robust and reliable fixation of the distal tibiofibular syndesmosis. The modified technique is devoid of the concern regarding the use of screw fixation and can reduce the risk of displacement or elongation and skin irritation associated with the suture button.

Intraosseous lipomas are one of the rarest bone tumors found in the body. The incidence has been reported to be <0.1% of all primary bone tumors. ⋯ This article describes a case of a pathologic fracture secondary to a large intraosseous lipoma, the surgical treatments, and the subsequent resolution of symptoms. The purpose of our report was 3-fold: (1) to increase awareness of intraosseous lipomas and their potential to cause pathologic fractures in the calcaneus; (2) to suggest a possible treatment protocol for intraosseous lipomas in the calcaneus; and (3) to describe a rare case of an intraosseous lipoma of the calcaneus not located exclusively in the neutral triangle.

Intramedullary screw fixation has been the most common treatment for fifth metatarsal base fractures. However, screw application will not achieve accurate reduction in fractures with small fragments, osteoporotic bone, or Lawrence zone 1 fractures. Because of the similar anatomic architecture between the distal ulna and the fifth metatarsal base, the purpose of the present study was to assess the results of a locking compression plate distal ulna hook plate in stabilizing displaced zone 1 or 2 fifth metatarsal base fractures. ⋯ Three patients developed post-traumatic cubometatarsal arthrosis, and 1 patient developed sural nerve neurapraxia. In our experience, the distal ulna hook plate achieved a high rate of bony consolidation and anatomically suitable fixation in zone 1 or 2 fifth metatarsal base fractures. We suggest that the locking compression plate distal ulna hook plate should be considered as an alternative treatment of multifragmentary, osteoporotic, and tuberosity avulsion (zone 1) fifth metatarsal base fractures.

Lisfranc fracture-dislocation can be a devastating injury with significant long-term sequelae, including degenerative joint disease, progressive arch collapse, and chronic pain that can be potentiated if not effectively treated. We present a case to demonstrate our preferred surgical approach, consisting of combined medial column primary arthrodesis, middle column open reduction internal fixation, and lateral column pinning, with the primary goal of minimizing common long-term complications associated with Lisfranc injuries. We present the case of a typical patient treated according to this combined surgical approach to highlight our patient selection criteria, rationale, surgical technique, and operative pearls. ⋯ Lisfranc fracture-dislocations often exhibit primary dislocation to the medial column and are conducive to arthrodesis to stabilize the tarsometatarsal complex. The middle column frequently involves comminuted intra-articular fractures and will often benefit from less dissection required for open reduction internal fixation instead of primary fusion. We propose that this surgical approach is a viable alternative technique for primary treatment of Lisfranc fracture-dislocation injuries.
