Effect of the Dutch Hip Fracture Audit implementation on mortality, length of hospital stay and time until surgery in elderly hip fracture patients; a multi-center cohort study.

BACKGROUND: In 2040 the estimated number of people with a hip fracture in the Netherlands will be about 24,000. The medical care for this group of patients is complicated and challenging. Multidisciplinary approaches aim to improve clinical outcome. Quality indicators that gain insight in the treatment and outcome of hip fracture patients may help to optimize and monitor the standard of medical care. The Dutch Hip Fracture Audit (DHFA) is a new multidisciplinary quality indicator that is implemented in the Dutch hospitals in 2017. AIM: The aim of this study was to determine the effect of the implementation of the DHFA on 30-day mortality, length of hospital stay and time until surgery in elderly with a hip fracture in the Netherlands. METHODS: A multicenter retrospective comparative cohort study was conducted and data were extracted from the Dutch Nationwide Trauma Registration (LTR). Included were patients aged 60 years and older with a hip fracture (femoral neck and trochanteric) and admitted in one of the ten participating hospitals registered in 2015 and 2017. Data from 2015, before implementation of DHFA, were compared with data from 2017, when the DHFA was implemented. The primary outcome was 30-day mortality; secondary outcomes were length of hospital stay and time until surgery. Multivariable regression models were used to compare outcomes between groups. RESULTS: 3808 patients were included, 1839 in the 2015 cohort and 1969 in the 2017 cohort. 29% was male; mean age 82 years. The multilevel analysis showed a positive non-significant difference between groups on the primary outcome30-day mortality (OR adjusted 1.23, 95%CI 0.93 - 1.63). The secondary outcomes length of hospital stay (adjusted effect estimates -0.002, 95%CI -0.03 - 0.03) and time until surgery (adjusted effect estimates 0.292, 95%CI -2.68 - 3.26) showed no differences between groups. CONCLUSIONS: Implementation of the DHFA quality indicator does have a positive non-significant trend on 30-day mortality, but showed no impact on length of hospital stay and time until surgery. More research on relevant quality indicators seems therefore mandatory.

Spontaneous sternal fracture due to multiple myeloma requiring extensive surgical repair.

Spontaneous sternal fracture is a well-known complication of multiple myeloma due to osteolytic bone lesions. The possibility of a multiple myeloma should be thoroughly investigated in patients presenting with a spontaneous sternal fracture. This work up should go beyond protein electrophoresis alone as a monoclonal paraprotein is not always present. In some cases, the myeloma plasma cell clone produces only the free light chain (κ or λ) or may even be non-secretory. The underlying plasma cell dyscrasia is treated with chemotherapy and, if needed, local radiotherapy. However, for patients with a fracture causing persistent pain and physical discomfort, internal fixation may be additionally required. We present a case of a patient who presented with a displaced pathological sternal fracture. She was treated with chemotherapy, radiotherapy and an open reduction and internal fixation with a Locking Compression Plate (LCP). This technique offers a feasible option for rigid fixation of pathological fractures.

Adductor longus tendon rupture mistaken for incarcerated inguinal hernia.

An incarcerated inguinal hernia is a common diagnosis, since the risk of an inguinal hernia incarcerating or strangulating is around 0.3-3%. An acute rupture of the adductor longus tendon is rarely seen and mostly affects (semi-) professional sportsmen. We present a case of a patient with an assumed incarcerated inguinal hernia which turned out to be a proximal adductor longus tendon rupture. If patients without a history of inguinal hernia present themselves with acute groin pain after suddenly exorotating the upper leg, a rupture of the adductor longus tendon should be considered. Both surgical and non-surgical treatment can be performed.

Insertion of intramedullary nails from the suprapatellar pouch for proximal tibial shaft fractures. A technical note.

Intramedullary nailing of proximal tibial fractures can be difficult when using the standard entry portal. We evaluated the suprapatellar portal, using a midline quadriceps tendon incision, to perform intramedullary nailing of the tibia. Seven patients were treated with this adaptation of the standard intramedullary nailing procedure. An arthroscopy was done before and after the nailing procedure. No special equipment was used to perform the intramedullary nailing. We evaluated the handling and necessary modifications of the standard intramedullary technique to introduce the locked tibial nail through the suprapatellar approach. We found this technique not necessarily more difficult than the standard intramedullary nailing of the tibia through the infrapatellar entry portal. Although the patients did not complain of patellofemoral discomfort after the suprapatellar nailing, definitive scuffing of the cartilage in the lower part of the femoral trochlea was visible. Introduction of a locked tibial nail via the suprapatellar approach was found to be possible and even advantageous for some complex upper tibial shaft fractures in compromised limbs. Some possible downsides of this approach need to be taken into account but, in some cases, they can be outweighed by the benefits.

Survival of closing-wedge high tibial osteotomy: good outcome in men with low-grade osteoarthritis after 10-16 years.

BACKGROUND AND PURPOSE: High tibial valgus osteotomy (HTO) is a well-accepted treatment for medial unicompartmental osteoarthritis of the knee with varus alignment in relatively young and active patients. Controversies about the factors affecting survival of HTO still exist. We assessed preoperative risk factors for failure of closing-wedge HTO at long-term follow-up. PATIENTS AND METHODS: A cohort of 100 patients with a mean age of 49 (24-67) years, who had closing-wedge HTO performed between January 1991 and December 1996, were analyzed retrospectively. A survival analysis was carried out according to the Kaplan-Meier method. Logistic regression analysis was used to assess the association between failure of the osteotomy and known potential preoperative risk factors. RESULTS: The probability of survival for HTO was 75% (SD 4%) at 10 years with knee replacement as the endpoint. Female sex and osteoarthritis of grade > or = 2 were identified as preoperative risk factors for conversion to arthroplasty 10 years after HTO. INTERPRETATION: Our findings suggest that ideal candidates for corrective osteotomy are men with symptomatic medial compartmental osteoarthritis of Ahlback grade 1, who, 10 years after surgery, have an almost tenfold lower probability of failure of HTO than women with more advanced osteoarthritis.

The whole leg radiograph: standing versus supine for determining axial alignment.

The whole leg radiograph (WLR), the standard technique for determining axial alignment, is usually taken in a standing position, although some prefer the supine position. To determine the difference between these two positions, we performed a standing and a supine WLR in 20 patients with a varus alignment. We found an average of 2 degrees more varus deviation in the standing position than in the supine position.
