Axial and tangential views of the acromioclavicular joint: the introduction of new projections.

Background: Routine anteroposterior radiographs of the acromioclavicular (AC) joint with or without weight bearing have limitations in demonstrating the AC joint. Transarticular fixation with Kirschner wire is a treatment choice for AC dislocations. However, percutaneous fixation of the AC joint is technically demanding.

Application of labeled radioimmunoimaging tracing in detecting pulmonary embolism in rabbits after bone cement perfusion and relevant treatment effects.

Background: During the process of bone cement joint replacement, some patients show a series of complications, such as a sudden drop in blood pressure or dyspnea. The cause of the complication is considered to be due to emboli caused by the femur prosthesis insertion. The purpose of the present study was to detect the pulmonary embolism in rabbits after bone cement perfusion by radioimmunoimaging, and to explore its protective measures.

Safe drilling angles and depths for plate-screw fixation of the clavicle: avoidance of inadvertent iatrogenic subclavian neurovascular bundle injury.

Background: Plate fixation is frequently used to repair clavicle fractures, but over drilling can cause subclavian neurovascular bundle damage. The aims of this study were to investigate the anatomic relationship between the clavicle and subclavian neurovascular bundle and to determine safe drilling angles and depths.

Methods: Twenty-six healthy subjects underwent magnetic resonance imaging.

The role of the calcar femorale in stress distribution in the proximal femur.

Objective: To investigate the role of the calcar femorale in stress distribution in the proximal femur.

Methods: Twenty-five specimens of proximal femurs were fixed to simulate single-limb stance. Strain gauges were applied to record the strain under different loads.

Modified distally based sural nerve flaps in acute traumatic forefeet reconstructions.

Conventional reversed sural flaps have been used to cover lower one-third of the leg defects. However, the experience of the authors indicates that when the soft-tissue defect located at the dorsum of the metatarsophalangeal joint, distal marginal necrosis of the flaps usually occurs, which is the exact part of the flap that one needs the most. Finding a new method to augment the blood supply of the flap can be a difficult task.

[Clinical epidemiological analysis of adult spiral tibial shaft fracture associated with ipsilateral posterior malleolar fracture].

Objective: To investigate the clinical epidemiological features of adult spiral tibial shaft fracture associated with ipsilateral posterior malleolar fracture, a special kind of fracture.

Methods: The clinical data of 1685 cases of adult tibial and fibular shaft fracture were analyzed retrospectively. The cause and mechanism of spiral tibial shaft fracture associated with ipsilateral posterior malleolar fracture were studied in detail.

[Comparison of two kinds of fractures involving posterior malleolar fracture].

Objective: To investigate the difference between the spiral tibial shaft fracture combined with ipsilateral posterior malleolar fracture.(TSPMF) and simple ipsilateral posterior malleolar fracture in ankle joint fracture in adults.

Methods: The sex, age, and type and mechanism of fracture of 82 patients with tibial shaft fracture associated with ankle joint fracture (TAF) and 28 patients with tibial shaft spiral fracture associated with ipsilateral posterior malleolar fracture (TSPMF) among 1685 cases of adult tibial and fibular shaft fracture and 330 patients with posterior malleolar fracture among 1871 cases of simple ankle joint fracture were analyzed.

[Treatment of complex calcaneal fractures under computer navigation: report of 130 feet].

Objective: To investigate the effects of computer navigation in the treatment of intra-articular calcaneal fractures.

Methods: 130 feet in 110 patients with intra-articular calcaneal fractures, 57 calcanei with fracture of Sander's type II, 45 of type III, and 28 cases of type IV, were treated with internal fixation under computer navigation, and were followed up for 16.3 months (6 - 24 months).
