Introduction Treatment of older adult hip fracture patients can be challenging and requires early postoperative mobilisation to prevent complications. Simple clinical tools to predict mobilisation/weight-bearing difficulties after hip fracture surgery are scarcely available and analysis of handgrip strength could be a feasible approach. In the present study, we hypothesised that patients with reduced handgrip strength show incapability to follow postoperative weight-bearing instructions. Materials and methods Eighty-four patients aged ≥ 65 years with a proximal femur fracture (trochanteric, n = 45 or femoral neck, n = 39), who were admitted to a certified orthogeriatric center, were consecutively enrolled in a prospective study design. Five days after surgery (intramedullary nailing or arthroplasty), a standardised assessment of handgrip strength and a gait analysis (via insole forcesensors) was performed. Results Handgrip strength showed positive correlation with average peak force during gait on the affected limb (0.259), postoperative Parker Mobility Score (0.287) and Barthel Index (0.306). Only slight positive correlation was observed with gait speed (0.157). These results were congruent with multivariate regression analysis. Conclusion Assessment of handgrip strength is a simple and reliable tool for early prediction of postoperative mobilisation complications like the inability to follow weight-bearing instructions in older hip fracture patients. Follow-up studies should evaluate if these findings also match with other fracture types and result in personalised adjustment of current aftercare patterns. In addition, efforts should be made to combine objectively collected data as handgrip strength or gait speed in a prediction model for long-term outcome of orthogeriatric patients.

Reduced mobility is a severe threat to the clinical outcomes and survival of elderly hip fracture patients. These patients generally struggle to comply with partial weight bearing, yet postoperative weight-bearing restrictions are still recommended by nearly 25% of surgeons. Therefore, we hypothesized that weight-bearing restrictions in elderly hip fracture patients merely leads to reduced mobility, while transposing full weight to the fractured extremity remains unaffected disregarding the prescribed aftercare. 41 equally treated patients with pertrochanteric fractures were enrolled consecutively in a maximum care hospital in a pre–post study design (level of evidence 2). A study group of 19 patients was instructed to maintain partial weight bearing (PWB), whereas the control group of 22 patients was instructed to mobilize at full weight bearing (FWB). All patients were asked to participate in a gait analysis using an insole force sensor (loadsol®, Novel, Munich, Germany) on the fifth postoperative day. The postoperative Parker Mobility Score in the PWB group compared to the FWB group was significantly reduced (3.21 vs. 4.73, p

Sarcopenia is a common geriatric syndrome and can lead to falls and fragility fractures. It is associated with a decline of muscle fiber numbers and size. Muscle biopsies of the vastus lateralis muscle were taken from thirty-two patients with hip fracture (18 women and 14 men; mean age: 82.2 ± 6.2 years). Serial cross sections of skeletal muscle were labeled with myosin heavy chain slow (fiber type-1) and fast (fiber type-2) antibodies in order to measure the size, ratio and percentage of mixed fiber types. The presence of sarcopenia was defined according to the EWGSOP2 criteria by using BIA and handgrip strength measurement. Sarcopenia was identified in 5 patients (3 women and 2 men), probable-sarcopenia in 11 patients (4 women and 7 men). Significant differences in fiber diameter were found for fiber type-2 in men but not in women. Only 1–3% mixed fiber types were found in sarcopenic patients, indicating a final stage where reinnervation is not possible to occur anymore. Muscle fiber type-2 atrophy seems to be a histological marker for sarcopenia in men.

Zusammenfassung Hintergrund Die häufigsten und vital bedrohlichsten Fragilitätsfrakturen sind die proximalen Femurfrakturen. Aufgrund der demografischen Entwicklung sind sie von zunehmender Bedeutung. Fragestellung Die hüftgelenksnahen Femurfrakturen sind überwiegend osteoporoseassoziiert und stellen oftmals eine chirurgische Herausforderung dar. Erhalt der Funktion und Selbstständigkeit sind die wesentlichen Behandlungsziele der Therapie von orthogeriatrischen Patienten. Die Stabilität der Osteosynthese kann durch Augmentationstechniken zusätzlich optimiert werden. Material und Methode Das am häufigsten angewendete Augmentationsverfahren ist die Zementaugmentation des proximalen Femurnagels Antirotation (PFNA) bei pertrochantären Femurfrakturen. Hiermit soll die Voraussetzung zur sofortigen vollbelastenden Mobilisation geschaffen werden. Ergebnisse Die gute Frakturheilung der PFNA-Marknagelosteosynthese ohne Hinweise auf zementassoziierte Komplikationen konnte in klinisch-prospektiven Studien gezeigt werden. Schlussfolgerung Die Sekundärprävention stellt neben der optimalen operativen Versorgung den entscheidenden Behandlungspfeiler zur Prävention weiterer Frakturen dar. Auf Basis der aktuellen Literatur soll dieser Artikel einen Überblick über die Zementaugmentation zur Behandlung proximaler Femurfrakturen bieten.

Early mobilization following hip fracture surgery is of superior importance especially in elderly hip fracture patients. Reduced mobilization can result in complications and increased mortality. In this study a gait analysis was performed using force-measuring insoles. We hypothesized, that patients with femoral neck fractures treated with hip replacement surgery load the affected limb more compared to patients with pertrochanteric fractures treated with fracture fixation. All patients (> 65 years) treated for a femoral neck fracture with hip replacement or a pertrochanteric fracture, respectively using fracture fixation with intramedullary nailing, were consecutively included in this study. For gait analysis, specific insole forcesensors (Loadsol®) were inserted into the footwear. Five days after surgery gait analysis was performed with a defined walking distance and all patients were instructed to transpose full weight. 20 patients following hip replacement surgery and 27 patients following intramedullary nailing were included. The hip replacement group loaded the affected limb with an average of 74.01% (SD 13.6) of bodyweight, while the fracture fixation group loaded a significantly reduced average of 62.70% (SD 8.3; p = 0.002). The results of the present study indicate that patients suffering from pertrochanteric fractures following fracture fixation are struggling to fully load the affected leg compared to patients suffering from femoral neck fractures treated with hip replacement surgery. The focus of further studies should concentrate on alternative analgesia and verify the cause of the observed difference in order to facilitate early full weight bearing especially in hip fracture patients following fracture fixation. The results indicate that in elderly patients, the fracture pattern and thus the surgical approach lead to a different weight bearing pattern. The primary therapeutic goal for elderly patients must be early mobilization at full weight bearing.

Use of standardized cement augmentation of the proximal femur nail antirotation (PFNA) for the treatment of trochanteric fragility fractures, which are associated with high morbidity and mortality, to achieve safer conditions for immediate full weight-bearing and mobilization, thus, improving preservation of function and independency of orthogeriatric patients. Trochanteric fragility fractures (type 31-A1–3). Ipsilateral arthritis of the hip, leakage of contrast agent into the hip joint, femoral neck fractures. Reduction of the fracture on a fracture table if possible, or minimally invasive open reduction of the proximal femur, i. e., using collinear forceps if necessary. Positioning of guidewires for adjustment of the PFNA and the spiral blade, respectively. Exclusion of leakage of contrast agent and subsequent injection of TRAUMACEM™ V+ into the femoral head–neck fragment via a trauma needle kit introduced into the spiral blade. Dynamic or static locking of the PFNA at the diaphyseal level. Immediate mobilization of the patients with full weight-bearing and secondary prevention, such as osteoporosis management is necessary to avoid further fractures in the treatment of these patients. A total of 110 patients older than 65 years underwent the procedure. Of the 72 patients available for follow-up (average age 85.3 years), all fractures healed after an average of 15.3 months. No complications related with cement augmentation were observed. Approximately 60 % of patients achieved the mobility level prior to trauma.

For elderly trauma patients, a basic goal is early mobilization, as immobilization can trigger various complications, such as venous thromboembolism, pneumonia, urinary tract infections, and pressure ulcers. Although partial weight-bearing has been shown to significantly increase mortality compared with unrestricted weight-bearing, it remains a frequent recommendation of aftercare following lower-extremity fracture fixation.An insole force sensor was used to measure true postoperative weight-bearing by patients ≥75 years of age treated for hip fracture compared with patients 18 to 40 years of age treated for ankle fracture. Both groups were instructed to maintain partial weight-bearing on the affected limb (≤20 kg) postoperatively. Following standardized physiotherapy training, gait analysis was performed.None of the patients in the elderly test group were able to comply with the weight-bearing restriction as recommended. We found that 69% (11 of 16) of the patients exceeded the specified load by more than twofold, whereas significantly more patients in the younger control group (75% [14 of 18]) achieved almost the entire weight-bearing restriction (p0.001). Only 1 of the elderly patients was able to comply with the predetermined weight-bearing restriction, and only for a short period of time. In comparison, significantly more patients in the control group (89% [16 of 18]; p0.001) maintained the partial load for nearly the entire time during gait analysis.Elderly patients seem to be unable to maintain weight-bearing restrictions. As early mobilization of geriatric trauma patients is an important element for a successful rehabilitation, the directive of postoperative partial weight-bearing for these patients should be abandoned.Therapeutic Level II.

Introduction Orthogeriatric ankle fractures seem to play an essential role in terms of quality of life in the elderly. Knowledge of the outcome after orthogeriatric ankle fractures is sparse. The present study investigates the outcome after surgically treated ankle fractures at a certified orthogeriatric trauma center. Material & Methods A retrospective observational study was performed investigating the outcome of surgically treated ankle fractures in orthogeriatric patients between 2015-2017. Outcome parameters included but were not limited to the EQ-5D 3 L, Barthel Index, Karlsson Score and the Charlson Comorbidity Index. Housing situation and mobility were evaluated and potential associations to the fracture pattern and the related treatment strategy were investigated. Results In total, 58 patients were included (age 77.7 ± 6,2 years). The majority were AO-44 B2 fractures (72%). General outcome was related to the Parker score; a Parker Score of 9 prior surgery was independently associated with an improved outcome according to the EQ-5D 3 L and Barthel Index. Patients under 80 years of age also had better results. Place of residence did not significantly change after surgery. Neither different types of implants nor initial use of an external fixator (e.g. open fractures) did influence outcome. A wound healing impairment was found in 10% of our patients whereas the overall unplanned reoperation rate was 7%. Overall complication rate was 20%, one-year mortality was 10%. Conclusions Surgically treated ankle fractures in the elderly which are treated in a certified geriatric fracture center seem to have limited negative effect on their quality of life. We did not observe the otherwise often demonstrated high mortality rates, but still nearly half of the patients demonstrated perioperative complications, which emphasizes the need for optimal perioperative care at an orthogeriatric trauma center. Since there was a reasonable number of patients with wound healing issues this study supports the idea of a staged protocol using external fixation with secondary ORIF.
