Unstable intertrochanteric femur fractures: is there a consensus on definition and treatment in Germany?

ABSTRACT:

Background

Extramedullary and intramedullary implants have improved in recent years, although consensus is lacking concerning the definition and classification of unstable intertrochanteric fractures, with uncertainties regarding treatment.

Questions/purposes

We conducted a national survey of practicing chairpersons of German institutions to determine current perspectives and perceptions of practice in the diagnosis, management, and surgical treatment of unstable intertrochanteric fractures.

Methods

Between January and February 2010, we emailed 575 German chairpersons of trauma and/or orthopaedic departments, asking them to complete a 26-question web-based survey regarding three broad domains: fracture classification and instability criteria, implants and surgical treatment algorithms, and timing of operations. Response rate was 42%.

Results

There was a clear preference for use of the AO/OTA fracture classification with geographic variations. Absence of medial support was considered the main criterion for fracture instability (84%), whereas a broken lateral wall and detached greater trochanter were considered by 4% and 5% of the respondents, respectively, to determine instability. Two percent routinely fixed unstable intertrochanteric fractures with extramedullary devices. Ninety-eight percent of German hospitals reportedly perform surgery within 24 hours after admission. Time to surgery was dependent on hospital level, with more direct surgeries in Level I hospitals.

Conclusions

Despite varying opinions in the literature in recent years, we found some instability criteria (lateral wall breach, a detached greater trochanter) played a minor role in defining an unstable intertrochanteric fracture pattern. Despite recent meta-analyses suggesting clinical equivalence of intra- and extramedullary implants, few respondents routinely treat unstable intertrochanteric fractures with extramedullary plates. Additional studies are required to specify the influence of fracture characteristics on complication rate and function and to establish a classification system with clear treatment recommendations for unstable intertrochanteric fractures.

Project description:BackgroundHip fractures usually occur in old aged patients with osteoporotic bone. Management of hip fractures in old aged patient is aimed to ambulate patient immediately and to restore the pre-operative ambulation. Proximal femur replacement is an effective treatment option in elderly patient with osteoporotic bones. It allow immediate weight bearing and early return to preoperative ambulatory status and minimizes the chances of systemic complication associated with prolong bed rest associated with internal fixation. This study is aimed to review the outcome of the patients whom underwent proximal femur replacement as primary treatment for the patient with comminuted intertrochanteric and sub trochanteric fracture.Patients and methodThis is a study conducted in our university hospital which is a tertiary-care level-1 trauma center. A retrospective analysis of 21 patients who underwent proximal femur replacement for comminuted intertrochanteric and sub trochanteric fracture, age more than 60 years during the period from April 2011 to March 2018 was conducted. Data collected included: age, gender, comorbidities, mechanism of injury, type of fracture, functional outcome (calculated via Harris Hip Score) and one year mortality.ResultsThe mean age of the patients was 74.05(range 64-91) years, out of which 13 (61.8%) were female and 8 (38.0%) were male. The mean follow up was 32.6(8-91 months).Immediate post-operative ambulation status was full weight bearing (FWB) in 17 patients (80.9%) of the patients while three patients (19.0%) had non-weight bearing (NWB) due to associated co-morbidities. The mean preoperative Harris Hip score was 68.0, while the mean postoperative Harris Hip score was 66.5 at last follow up. Post operatively one patient (4.7%) developed pulmonary embolism, one patient developed dislocation. One patent (4.7%) died of sepsis from implant infection at 8 months after surgery.ConclusionPrimary Proximal femoral replacement in a viable option in old aged patients with poor bone quality who developed intertrochanteric and subtrochanteric fracture. According to our study, with mortality rate comparable to that of primary fixation, yet with the added advantage of immediate post op ambulation and reduced incidences of decubitus ulcers, atelectasis and DVT.

Project description:Background:Proximal femoral nail antirotation-2 (PFNA-2) has been widely used to treat intertrochanteric fractures with varied outcomes in the previous studies. The entry point of the nail plays an important role in achieving acceptable reduction, stable fixation, and avoiding implant related complications. This study was proposed to determine the optimal greater trochanteric entry point for PFNA-2 in unstable intertrochanteric femur fractures. Methods:We conducted an observational study on 40 patients with unstable intertrochanteric fracture treated with PFNA-2 implant in a tertiary care hospital. The patients were grouped into two based on the entry point: group L for lateral and group M for medial entry. Randomization was carried out by assigning the patients to the group by alternate allocation. The quality of reduction, tip apex distance, Cleveland index, and all the complications were noted. The final follow-up was conducted at six months. The functional outcome was evaluated using modified Harris hip score. The data analysis was performed using Student's t-test, chi square test, and Mann-Whitney test. A P value below 0.05 was considered significant. Results:Forty patients with 20 patients treated with medial entry point were included in group M and 20 patients in group L with lateral entry point. The group L had an average tip apex distance of 20.53 and group M had 20.02 (P=0.8). The complication of screw back out was seen in 3 out of 4 patients with poor reduction in group L. As per the Cleveland index, 6 patients in each group had suboptimal position and 4 out of 6 patients in group L with suboptimal position had screw back out. The lateral cortex impingement was seen in 14 patients of group L and 6 patients in group M with significant comparison (P=0.01). Three patients in group L had varus collapse with screw back out. Also, none in group M (0.05). The average modified Harris hip score in group L at six months follow-up was 71.94 and 76.8 in group M (P=0.84). Conclusion:Overall, to achieve good quality of fixation and reducing damage to gluteus medius entry point for PFNA-2 should be 5?mm medial to the greater trochanter tip.

Project description:BackgroundThe aim of this meta-analysis was to evaluate the advantages and disadvantages of proximal femoral nail anti-rotation (PFNA) versus dynamic hip screw (DHS) for the treatment of unstable intertrochanteric fractures, including the available evidence drawn from the literature.MethodsA systematic search was conducted to identify available and relevant randomized controlled trials and retrospective comparative observational studies regarding PFNA compared against DHS in treating unstable femoral intertrochanteric fractures in Embase, PubMed, Cochrane Library, Web of Science, and Scopus Online up to February 12, 2022. Data from the included studies were extracted independently by 2 reviewers and analyzed using RevMan 5.3, and the quality of the studies was assessed.ResultsFive randomized controlled trials and 12 observational studies were recruited and met the inclusion criteria, which consisted of 1332 patients with PFNA and 1271 patients with DHS. The results of the meta-analysis showed that, compared with the DHS, PFNA exhibited a beneficial role in postoperative Harris Hip Scores, operation time, intraoperative blood loss, length of hospital stay, fracture healing time and full weight-bearing time, limb shortening, cutout, reoperation, union problems, the varus collapse of the femoral head/neck, and infection; however, DHS was superior to PFNA in hidden blood loss (relative risk [RR] = 139.81, 95% confidence interval [CI] [136.18, 143.43], P < .00001), postoperation drainage (RR = -17.85, 95% CI [-30.10, -5.60], P = .004), total blood loss (RR = 50.34, 95% CI [42.99, 57.69], P < .00001), and femoral shaft fracture (RR = 4.72, 95% CI [1.15, 19.32], P = .03) treated by DHS were significantly decreased, compared with those by PFNA; however, no significant differences were observed in tip-apex distance, fixation failures, screw migration, or other complicants between the 2 surgical methods.ConclusionAnalysis of a large number of relevant clinical indicators available shows that PFNA has better clinical manifestation than DHS in treating unstable femoral intertrochanteric fractures.
