Although the field of geriatric trauma is – ironically – young, care for the elderly trauma patient is increasingly recognised as an important challenge, considering the worldwide trend towards increasing longevity.Increasing age is associated with physiological changes and resulting comorbidities that present multiple challenges to the treating physician.Even though polytrauma is less likely with increasing age, lower-energy trauma can also result in life-threatening injuries due to the reduced physiological reserve.Mechanisms of injury and resulting injury patterns are markedly changed in the elderly population and new management strategies are needed. From initial triage to long-term rehabilitation, these patients require care that differs from the everyday standard.In the current review, the special requirements of this increasing patient population are reviewed and management options discussed. With the increase in orthogeriatrics as a speciality, the current status quo will almost certainly shift towards a more tailored treatment approach for the elderly patient. Further research expanding our current knowledge is needed to reduce the high morbidity and mortality rate.Cite this article: Braun BJ, Holstein J, Fritz T, Veith NT, Herath S, Mörsdorf P, Pohlemann T.

Cilostazol, a selective phosphodiesterase-3 inhibitor, is known to control cyclic adenosine monophosphate (c-AMP) and to stimulate angiogenesis through upregulation of pro-angiogenic factors. There is no information, however, whether cilostazol affects fracture healing. We, therefore, studied the effect of cilostazol on callus formation and biomechanics during fracture repair. Bone healing was analyzed in a murine femur fracture stabilized with an intramedullary screw. Radiological, biomechanical, histomorphometric, histochemical, and protein biochemical analyses were performed at 2 and 5 weeks after fracture. Twenty-five mice received 30 mg/kg body weight cilostazol p.o. daily. Controls (n ¼ 24) received equivalent amounts of vehicle. In cilostazol-treated animals radiological analysis at 2 weeks showed an improved healing with an accelerated osseous bridging compared to controls. This was associated with a significantly higher amount of bony tissue and a smaller amount of cartilage tissue within the callus. Western blot analysis showed a higher expression of cysteine-rich protein 61 (CYR61), bone morphogenetic protein (BMP)-4, and receptor activator of NF-kappaB ligand (RANKL). At 5 weeks, improved fracture healing after cilostazol treatment was indicated by biomechanical analyses, demonstrating a significant higher bending stiffness compared to controls. Thus, cilostazol improves fracture healing by accelerating both bone formation and callus remodeling. ß
Introduction
Femoral neck fractures (FNF) are one of the most frequent fractures among elderly patients and commonly require surgical treatment. Bipolar hip hemiarthroplasty (BHHA) is mostly performed in these cases.
Material and methods
In the present retrospective study geriatric patients with FNF (n = 100) treated either by anterior minimal-invasive surgery (AMIS; n = 50) or lateral conventional surgery (LCS; n = 50) were characterized (age at the time of surgery, sex, health status/ASA score, walking distance and need for walking aids before the injury) and intraoperative parameters (duration of surgery, blood loss, complications), as well as postoperative functional performance early (duration of in-patient stay, radiological leg length discrepancy, ability to full weight-bearing, mobilization with walking aids) and 12 months (radiological signs of sintering, clinical parameters, complication rate) after surgery were analyzed.
Results
Patients in the AMIS group demonstrated a reduced blood loss intraoperatively, while the duration of surgery and complication rates did not differ between the two groups. Further, more patients in the AMIS group achieved full weight-bearing of the injured leg and were able to walk with a rollator or less support during their in-patient stay. Of interest, patients in the AMIS group achieved this level of mobility earlier than those of the LCS group, although their walking distance before the acute injury was reduced. Moreover, patients of the AMIS group showed equal leg lengths postoperatively more often than patients of the LCS group. No significant differences in functional and surgery-related performance could be observed between AMIS and LCS group at 12 months postoperatively.
Conclusions
In conclusion, geriatric patients treated by AMIS experience less surgery-related strain and recover faster in the early postoperative phase compared to LCS after displaced FNF. Hence, AMIS should be recommended for BHHA in these vulnerable patients.
