Background: Sternum fractures are mostly located on the sternal corpus, seldom on the manubrium.Fractures of the sternal manubrium are, however, more frequently associated with severe concomitant injuries of thoracic organs, and therefore deserve special attention. In addition, in its function as a capstone in between the anterior chest wall and the shoulder girdle, it is exposed to a multiplicity of forces. Therefore the questions arise what types of fractures are observed in today's clinical practice, how to classify them and which treatment options are available. This study reports on different types of fractures which involve the manubrium sterni. Methods: Between January 2012 and October 2014, data was collected from all severely injured patients (ISS ≥16), which received a CT scan of the thorax in our Level-I-Trauma Center and retrospectively analyzed concerning sternal fractures. Fracture type, collateral injuries, age, and information about the circumstances of the accident were noted. Results: Of 890 evaluable patients, 154 (17.3%) had a fracture of the sternum and 23 (2.6%) of the manubrium. Fractures of the manubrium appeared in following types: A-type-transverse fracture (n=11) in 1st intercostal space by direct blunt trauma or flexion of the torso with sagittal instability; B-type-oblique fracture (n=9) by seat belt injury with rotatory instability; C-type-combined, more fragmentary fracture (n=3) by direct blunt trauma with simultaneous flexion of the torso and multi directional instability. Fractures only little dislocation were treated conservatively, and unstable fractures were surgically stabilized (n=10). Conclusions: In summary, three main types of fractures could be found. A-type fractures were stabilized with a longitudinal plate osteosynthesis and B-type fractures with transverse positioned plates. To treat complex C-type fractures, plates with a T-or H-form could be a good solution.Level of evidence: Level III retrospective prognostic cohort study

Extensive invasive surgical approaches to the thoracic wall can be replaced by reduced invasive and muscle-sparing access combinations. A free-moving positioning of the arm and an accurate preoperative plan for minimizing approaches are essential. Minimally invasive plate techniques are very helpful adjuncts.

ESCR in recurrent PE achieved functional stabilization of the anterior chest wall combined with satisfactory results.

Background: Complex and mature funnel chest deformities are traditionally managed with open surgical procedures. Elastic stable chest repair (ESCR) has been used successfully and safely for relapse corrections. Does pure plate osteosynthesis in ESCR allow comparable corrective potency and implant safety as hybrid methods with metal bars? Methods: Data from 86 patients with open funnel chest correction between 2011 and 2015 were analyzed in this retrospective study. Exclusion criteria included being under 12 years of age, and having a history of septic wound healing disorder or other malignant diseases. Main groups consisted of ESCR and hybrid techniques, subgroups were primary and recurrence correction. Correction results and follow-up examinations at six and 12 weeks and at 1 year were statistically analyzed. Results: A total of 38 ESCR and 48 hybrid methods were analyzed. Bar implantation was required in 77% (recurrence 34%) of patients. All patients received plates with different combinations e.g., longitudinalsternal, costosternal and costo-sterno-costal. In all groups, follow-up uptake showed a funnel chest correction result at the anatomical level with healthy values according to the Haller index (ESCR 4.36-2.84, hybrid 6.99-2.74, P<0.001). No material dislocations were observed in any subgroup. Conclusions: ESCR and hybrid techniques represent promising and safe therapeutic approaches.
