Background: Lipomas are the most frequent benign soft tissue tumor that are rarely found in the hand and are exceptionally rare on the fingers. The aim of this study was to investigate lipomas of atypical locations, so that they can be taken into account when making a differential diagnosis of a tumor of the hand or fingers. Methods: We studied a group of 27 patients diagnosed with lipoma of the wrist, palm, and fingers. The diagnosis was made by clinical and imaging examinations. Surgical treatment was established based on symptoms of pain, paresthesias, functional impairment, or aesthetic concerns. Treatment outcomes were assessed clinically at 1.5 years post-intervention. Results: Sizes over 5 cm were recorded in five cases, with the largest lipoma being 8 by 5 by 3.5 cm in size and weighing 125 g, located in the palm. There was one case of spontaneous tendon rupture and one case of carpal tunnel syndrome. There was no recurrence recorded at 1.5-year follow-up. Conclusions: Lipomas in the palm and fingers are rare entities (with more men affected), and surgical treatment consists of complete removal of the tumor and providing definitive healing. Despite their rarity, clinicians should consider lipomas when making differential diagnoses of soft tissue tumors of the hand.

Objectives: To assess the outcome of the sinus tarsi approach and C-Nail fixation of displaced intra-articular calcaneal fractures (DIACFs). Design: Prospective study. Setting: University Trauma Department. Patients: Sixty-four patients (mean age 44.3 years, 48 men and 16 women) with 75 DIACFs were treated between October 1, 2016 and December 31, 2018. Intervention: In all cases, the posterior facet was reduced through the sinus tarsi approach and fixed with one or 2 screws. After reducing all fragments to the articular block, the final fixation was performed percutaneously with C-Nail, locked with 6 screws. Main Outcome Measurements: Patients were assessed for restoration of the Böhler angle, complications, and overall fracture reduction. To assess the functional outcome, we used the Mean American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score and Maryland Foot Score after 12 months. Results: The Böhler angle improved from −0.5 degrees preoperatively to 28.6 degrees postoperatively. The articular step-off was reduced from 5.4 mm preoperatively to 0.6 mm postoperatively. The postoperative radiologic calcaneal score was 2.9, on average. Superficial wound edge necrosis was seen in 3 patients (4%) and superficial infection was observed in one (1.3%). After a 1-year follow-up, we recorded a mean American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score of 90.2 and a mean Maryland Foot Score of 91.2. Conclusions: After obtaining an anatomic reduction of the articular surface of the posterior facet with lag screws, the C-Nail represented a viable alternative to plate stabilization in the treatment of DIACFs, combining primary stability with low soft tissue complications. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Rationale: Floating-dislocated elbow is a severe and extremely rare injury in adults. Reviewing the literature, we found around 6 case reports regarding floating-dislocated elbow in adults. Patient concerns and diagnoses: We report 2 cases of this unusual injury association. Both patients suffered a high energy trauma – fall from a height. Initial X-rays (radiography) revealed in both cases the fractures above and below the elbow (floating elbow) and associated elbow dislocation (floating-dislocated elbow). One case was a type IIIB Gustilo-Anderson open fracture-dislocation with an intra-articular component (olecranon fracture). Interventions and outcomes: Each case had his own management problem regarding what to treat first: the dislocation or the associated fractures? Fractures were treated surgically by reduction and internal fixation, and after elbow dislocation reduction, the upper limb was immobilized in a long, well-padded plaster, with the elbow in 90° of flexion, for 3 weeks. Bone union was observed radiographically at 2 months after surgery in both cases. At the 2-year follow-up we recorded full upper limb recovery in terms of muscular trophism and elbow full range of motion. Lessons: In addition to adding 2 new cases to a lower number of such lesion associations in adults, we also added a new variant of floating-dislocated elbow which has not been reported until now in the literature. Prompt management of these injuries, with stable fixation of the fractures allowed for early rehabilitation with excellent 2-years functional outcome.
