Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis

ObjectiveMultiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients.MethodsMeta-analysis of 21 studies of 430 acetabular fractures with mean follow-up of 44 months (range, 17−97 months). Two independent researchers searched and evaluated the databases of Ovid, Embase, and United States National Library of Medicine using a Boolean search string up to December 2019. Population demographics and complications, including presence of heterotopic ossification (HO), dislocation, infection, revision rate, neurological deficits, and venous thromboembolic event (VTE), were recorded and analyzed.ResultsWeighted mean Harris Hip Score was 83.3 points, and 20% of the patients had reported complications. The most common complication was HO, with a rate of 19.5%. Brooker grade III and IV HO rates were lower at 6.8%. Hip dislocation occurred at a rate of 6.1%, 4.1% of patients developed VTE, deep infection occurred in 3.8%, and neurological complications occurred in 1.9%. Although the revision rate was described in most studies, we were unable to perform a survival analysis because the time to each revision was described in only a few studies. The revision rate was 4.3%.ConclusionsAcute THA is a viable option for treatment of acetabular fracture and can result in acceptable clinical outcomes and survivorship rates in older patients but with an associated complication rate of approximately 20%. Considering the limited treatment options, THA might be a viable alternative for appropriately selected patients.     

Absence of Case of Mucormycosis (March 2020–May 2021) under strict protocol driven management care in a COVID-19 specific tertiary care intensive care unit

AimsWith a sudden increase in cases of mucormycosis seen in Covid ?19 patients, we conducted a retrospective analysis of all admitted patients in a tertiary care covid-19 hospital looking at incidence of mucormycosis.MethodsIntensive care unit daily rounds data stored in an electronic format was retrieved by one of the consultants, looking for incidence of mucormycosis, diabetes mellitus, adherence to protocol for steroid use, glycemic control and use of monoclonal antibodies. Also, patients follow up data base of post covid Outpatients Department was searched for cases of mucormycosis.ResultsA total of 5248 patients were admitted between March 2020 to May 2021, of which 1027 were in ICU and 4221 in wards. Of the 1027 patients admitted in Intensive care unit, 915 received steroids and 417 had diabetes as existing co-morbidity. No case of mucormycosis was reported during the stay in the hospital and during immediate outpatient department follow up. The low dose steroids were administered as per state government protocol for treating COVID 19, a nurse driven strict glycemic control regime (blood glucose level was maintained between 140 and 180 mg/dl through the admission in ICU and was achieved consistently in 842 (82%) patients, followed along with minimal use of other immunomodulatory like monoclonal antibodies.ConclusionA strict adherence to protocol of low dose steroids coupled with strict glycemic control helped in eliminating the risk and incidence of mucormycosis in a tertiary care dedicated covid-19 hospital.     

A comprehensive 3D CT based classification of intertrochanteric fracture

IntroductionDespite advancements in surgical techniques complications like implant failure is very common after the fixation of intertrochanteric fractures. Classifying these complex fractures based on plain radiographs underestimates the complexity of these fractures which in turn leads to complications. We propose a comprehensive classification of the intertrochanteric fractures based on 3D Non Contrast Computed Tomography (3D NCCT) scan.Material and methodsA total of 102 patients (51 males and 51 females) with intertrochanteric fractures were included in this study conducted over a time period of 22 months in a Tertiary care center in North India. NCCT proximal femur of the intertrochanteric fracture patients was done to formulate a new CT classification system and classify all fractures. Intra and inter-observer reliability was tested using kappa variance.ResultsNew classification system was proposed which included 3 main and a total of 6 groups. All the fractures were classifiable into the new system. Kappa variance of the study showed a good intra and interobserver reliability (0.95 and 0.90) proving clinical agreement of the classification.ConclusionThis new 3D-CT based classification has the advantages of being easy, comprehensible with high intra and inter-observer reliability. This 3DCT based classification can prove to be useful to detect occult intertrochanteric fractures undetectable in plain radiographs as well as choosing the optimum treatment plan.     

Isolated bilateral fibular insufficiency fractures: Case report of an unusual entity

Insufficiency fractures are a type of stress fractures that occur due to physiological stress on weakened bones. These have certain sites of predilection of which an uncommon site is fibular shaft. Isolated bilateral fibular fractures have previously only been reported twice, where the causes were repeated trauma and fatigue fracture. Insufficiency fractures of both fibula in isolation have not previously been reported. We present this case where a young patient presented with these fractures and was found to have vitamin D deficiency on subsequent investigations.
