Fractures and fracture dislocations of carpometacarpal joints 2-5 may be easily overlooked. This can be explained by often subtle clinical and radiographic signs. In case of clinical suspicion with apparently normal standard x-rays, a computed tomography with thin slices should be promptly performed. Therapy is predominantly operative and aims at anatomic reduction and reconstruction of joint congruity. ⋯ To facilitate treatment decisions, especially concerning closed or open fixation, we have defined 3 pathomorphological patterns (types I-III). Decision criteria are sagittal or coronal plane of fracture, degree of destruction of the articular surface, and radial or ulnar location of the injury. Following operative therapy, early mobilization of all finger joints should be performed.

Few data exist on the epidemiological characteristics of thermal injuries in prehospital emergency care, especially in the context of air rescue. Therefore, this study aimed to analyze the epidemiology of pediatric and adult thermal injuries in the helicopter emergency medical service (HEMS) run by the Austrian Automobile Motorcycle Touring Club (OEAMTC) air rescue service from an almost nationwide sample. ⋯ In HEMS thermal injuries are infrequent but mostly life-threatening. Differences in epidemiological characteristics of pediatric and adult burns/scalds may have important operational, training and public health implications.

Injuries of the proximal interphalangeal joint (PIP joint) are common. They are frequently underestimated by patients and initial treating physicians, leading to unfavorable outcomes. Basic treatment includes meticulous clinical and radiological diagnosis as well as anatomical and biomechanical knowledge of the PIP joint. ⋯ In avulsions of the collateral ligaments and the palmar plate with or without involvement of bone, nonoperative treatment is preferred. Operative stabilization is reserved for large displaced bony fragments or complex instabilities. In central slip avulsion or rupture, osseous refixation, suture, or reconstruction is common and nonoperative treatment is limited to special situations like minimally displaced avulsions. In basal fractures of the middle phalanx, elimination of joint subluxation and restoration of joint stability are priority. If the fragments are too small for fixation with standard implants, therapeutic alternatives include refixation of the palmar plate, dynamic distraction fixation, percutaneous stuffing, or replacement by a hemihamate autograft. Early motion is initiated regardless of the treatment regime. Undertreatment leads to persistent swelling, instability, and limited range of motion, which are difficult to treat. Contributing factors are unnecessary immobilization, immobilization in more than 20° flexion or transfixation by K-wires. For residual limitations, nonoperative treatment with physiotherapists and splinting is first choice. Operative treatment is reserved for persistent flexion/extension contractures persisting for more than 6 months, as well as reconstructions in boutonniere and swan neck deformity and salvage procedures for destroyed joints.

X-rays are the standard imaging procedure for the diagnosis of pediatric long bone fractures. Recent studies show that ultrasound (US) imaging is also qualified to diagnose pediatric long bones fractures. Thus, the diagnosis and decision-making for the treatment of metaphyseal forearm fractures in children can be performed by solely using US. ⋯ US is also useful to exclude subcapital humeral fractures and to estimate fracture displacement. If a fracture of the subcapital humerus is present, additional radiographs are necessary to avoid overlooking of pathologic fractures. For reliable sonographic fracture diagnosis in childhood, a detailed history und exact clinical examination are required.
