Comparison of Outcomes of Long Versus Short Cephalomedullary Nails for the Fixation of Intertrochanteric Femur Fractures: A Systematic Review and Meta-analysis of 14,547 Patients.

Purpose: Intertrochanteric Femur Fractures (IFF) fixation could be done with short or long Cephalomedullary Nails (CMNs). Nevertheless, despite several studies in the literature, there has been a continued lack of consensus on which design of CMN is better than the other. Hence, the current review aimed to evaluate the evidence about short versus long CMNs for the fixation of IFF. Methodology: PRISMA guidelines were followed, and the protocol for the study was registered to PROSPERO. Four databases, Medline/PubMed, Embase, Scopus, and Cochrane Library, were searched. A total of 31 studies with 6 randomized trials (RCTs) and 25 non-randomized studies were included. Demographic data, follow-up period, and primary and secondary outcomes were extracted and evaluated from each of the included studies; statistical analysis was done by Review Manager Software version 5.4.1. Results: Fourteen thousand five hundred forty-seven patients were included in this review. Primary Outcomes: Long CMNs showed statistically significant lower rates of ipsilateral shaft femur refracture (OR 1.60, 95% CI 1.14, 2.24, p = 0.007); however, the difference was not statistically significant between the two groups for mortality at 30 days and within 1 year. Secondary Outcomes: Statistically significant shorter duration of surgery (MD-17.83 (95% CI - 22.03, - 13.63, p < 0.05), less intra-operative blood loss (MD - 62.65, 95% CI - 97.13 to - 28.17, p = < 0.05), and lower blood transfusion rates (OR 0.71, 95% CI 0.62, 0.83, p < 0.05) for short CMNs; no statistically significant difference for the length of hospital stay, implant-related complications, overall complications, re-operation rates, fluoroscopy time, and functional outcome between two groups of CMNs was seen. Conclusion: With shorter operative time, lesser intra-operative blood loss, and lower postoperative transfusion rates for short CMNs, they have certain benefits over longer CMNs. However, more distal shaft femur fractures were seen in the shorter version of nail, which should be considered before offering these nails to a patient; careful and individualized postoperative weight-bearing protocol could minimize the same.

Assessment of Usefulness of CT Scan in AO Classification of Intertrochanteric Fractures: A Prospective Observational Study.

OBJECTIVE: The sliding hip screw (SHS) is the gold standard for the management of stable intertrochanteric (IT) fractures. However, intramedullary implants are now being increasingly used for management of unstable IT fractures especially those with a compromised or vulnerable lateral wall. Therefore, accurate classification of fracture is important to ensure proper surgical planning and choice of implant. The AO classification for IT fractures is based on plain radiographs alone and many authors have reported it to have poor inter- and intra-observer agreement. Therefore, the objectives of the study were to assess the improvement in inter- and intra-observer agreement of the AO classification after addition of CT scan to plain radiographs, to assess the change in pattern of AO classification on addition of CT scan to plain radiographs and to assess percentage of times, stable lateral wall seen on plain radiographs is classified as unstable or broken on CT scans. METHOD: Fifty-four patients of intertrochanteric fracture were included in study. Plain radiographs of patients were shown to three orthopedic surgeons. They were asked to document the AO classification of the fracture, and comment on the integrity of the lateral wall. Then, CT scans with 3D reconstructions of the same patients were provided along with the radiographs and they were asked to classify the fracture again. Inter- and intra-observer agreement of the AO classification based on plain radiographs alone and once CT scan with 3D reconstruction was added to the plain radiographs was determined using Kappa coefficients. Pattern of change in classification on addition of CT scan to plain radiographs was also assessed. RESULT: The mean kappa value for inter- and intra-observer agreement for AO classification on plain radiographs alone were 0.58 (moderate) and 0.66 (substantial), respectively. Upon addition of CT scan to plain radiographs, both improved to 0.70 (substantial) and 0.77 (substantial), respectively. The AO classification of the fracture changed 28.70% times (93 of 324 observations) upon addition of CT scan to plain radiographs. 96.77% times (90 of 93 observations) the classification was upgraded to higher group, while it was downgraded in only 3.22% times (3 of 93). 55.91% times this change was observed in AO 31 A 2 group (52 of 93 observations). In 17.59% cases (57 of 324 observations), fractures which were classified as stable (A1.1-A2.1) on radiographs alone, were reclassified as unstable (A2.2-3.3) upon addition of CT scan to plain radiographs. In 11.4% cases (37 of 324 observations), the lateral wall was classified as vulnerable or broken on CT scans where it was classified intact on plain radiographs. CONCLUSION: Addition of CT scans with 3D reconstructions to plain radiographs improves the intra- and inter-observer agreement of the AO classification. Addition of CT scan results in change in classification of the fracture in about one out of three cases. This most commonly happens in the AO 31 A 2 group. Most of the times, this results in the classification of fracture being upgraded. Many fractures which are initially classified as stable (A1.1-A2.1) on radiographs are reclassified as unstable (A2.2-3.3) on addition of CT scans. The lateral wall is also classified as vulnerable or broken more number of times on CT scans than plain radiographs alone. Therefore, we conclude that CT scan with 3 D reconstructions definitely helps in better pre-operative classification of intertrochanteric fractures especially in select group of fractures (AO 31 A 2) where stability and integrity of lateral wall is difficult to assess.

Type III monteggia equivalent injury with compartment syndrome in an 8 year old child: A case report.

A rare case of a type III Monteggia fracture equivalent with compartment syndrome is reported here. Literature is very scanty about this rare combination of injuries which we are discussing. Timely intervention can lead to a satisfactory outcome even in these complex injuries.

Evaluation of Healed Status in Tuberculosis of Spine by Fluorodeoxyglucose-positron Emission Tomography/Computed Tomography and Contrast Magnetic Resonance Imaging.

BACKGROUND: The healed status (end-point of treatment) in tuberculosis (TB) spine is not defined; hence optimum antitubercular therapy (ATT) duration is unresolved. We, for the first time, prospectively evaluated the healed status in TB spine by fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) and contrast magnetic resonance imaging (MRI) with the objective to define end-point of treatment in TB spine. MATERIALS AND METHODS: Thirty seven patients of TB spine diagnosed on clinicoradio imaging/cytology/histologically/molecular methods were enrolled, treated and were evaluated radiologically, by contrast MRI and FDG-PET/CT at 9 months. ATT was stopped on contrast MRI-based healing or absence of FDG uptake on PET-CT. ATT was continued in active/resolving lesion. Repeat evaluation was done at 12, 18, 24, and 30 months till healing is demonstrated. In this research work, we got contrast MRI and FDG-PET/CT done for the patients from government institution free of cost, so patients did not have to bear the burden of cost of these investigations. RESULTS: Twenty-eight patients achieved healed status out of which 11 demonstrated healed status on contrast MRI and FDG-PET/CT both, 6 were MRI active (contrast enhancement) but FDG-PET/CT healed, 2 were MRI healed but FDG-PET/CT active (soft-tissue standardized uptake value <2.0), 9 patients were MRI incompatible due to stainless steel implants (n = 6), and in 3 patients MRI could not be done due to financial constraints and were declared healed on FDG-PET/CT. FDG-PET/CT showed healed bone lesion in 28/28 (100%) and on MRI 13/19 (68.42%), respectively. We had 6 patients whose spine was stabilized with stainless steel implants where MRI could not be performed, MRI was useful in 13/25 cases (52%) to demonstrate healed lesion. 7, 6, 6, 5, 1, 2, and 1 cases achieved healed status at 9, 12, 18, 24, 30, 36, and 48 months of ATT intake, respectively. CONCLUSIONS: FDG-PET/CT is more useful to demonstrate the healed status than MRI and is the only imaging to demonstrate healed status when MRI could not be performed due to metallic implants. All patients achieved healed status at variable length of ATT intake; hence TB spine should be treated by ATT till healed status (end-point of treatment) is demonstrated by FDG-PET/CT (absence of FDG uptake) or contrast MRI.

Factors Responsible for Redisplacement of Pediatric Forearm Fractures Treated by Closed Reduction and Cast: Role of casting indices and three point index.

BACKGROUND: Pediatric forearm fractures are still considered an enigma in view of their propensity to redisplace in cast. The redisplacement may be a potential cause for malalignment. We prospectively analyzed the role of risk factors and above casting indices in predicting significant redisplacement of pediatric forearm fractures treated by closed reduction and cast. MATERIALS AND METHODS: 113 patients of age range 2-13 years with displaced forearm fractures, treated by closed reduction and cast were included in this prospective study. Prereduction and postreduction angulation, translation, and shortening were noted. In addition, for distal metaphyseal fractures, obliquity angle was noted. In postreduction X-ray, apart from fracture variables, casting indices were also noted (cast index [CI] for all patients with three-point index [TPI] and second metacarpal radius angle in addition for distal metaphyseal fractures). In 2nd week, X-rays were again obtained to check for significant redisplacement. These patients were managed with remanipulation and casting or were operated if remanipulation failed. Comparison of various risk factors was made between patients with significant redisplacement and those which were acceptably reduced. A subgroup analysis of patients with distal metaphyseal fractures was done. RESULTS: Thirteen (11.5%) patients had significant redisplacement; all of them required remanipulation. No association with respect to age, sex, level of fracture, side of injury, surgeon's experience, number of bones fractured, and injury to definitive cast interval was seen. The presence of complete displacement in any of the plane in either of the bones was seen to be highly significant predictor of redisplacement (P < 0.001). Postreduction angulation more than 10° in any plane in either of the bone and fracture obliquity angle in distal metaphyseal fracture also had a highly significant association with redisplacement. There was a significant difference in the mean values of all three casting indices assessed. TPI was the most sensitive casting index (87.5%). CONCLUSIONS: Conservative management with aim of anatomical reduction, especially in patients with complete displacement, should be the approach of choice in closed pediatric forearm fractures. Casting indices are good markers of quality of cast.

Randomized controlled trial comparing stabilization of fresh close femoral shaft fractures in children with titanium elastic nail system versus stainless steel elastic nail system.

In vitro mechanical studies have demonstrated equal or superior fixation of pediatric femoral fractures with use of titanium elastic nails (TENS) as compared with stainless steel elastic nails (SSEN). SSEN are less expensive as compared to TENS. However, there are only two studies in the English literature which have compared the results of TENS and SSEN in paediatric femoral shaft fracture. The present study compares the clinical and radiological outcomes of femoral shaft fracture in patients 6-12 years of age, operatively stabilised either by TENS or SSEN. 35 children (6-12 years) with closed, post traumatic femoral shaft fractures were randomized into two treatment groups. Both groups underwent closed reduction internal fixation (CRIF) by either of the implants (TENS OR SSENS) as per randomization protocol and followed up for six months. Comparison of clinical and radiological outcomes in both the groups was done in terms of time to union of fracture and radiological angulations in coronal and sagittal plane. There was no significant difference in both groups with respect to fracture site tenderness and presence of bridging callus at fracture site at 3 weeks, 6 weeks and 6 months follow up (p-value = 1.000). There was no significant difference in radiological angulation rate in both groups in the sagittal (p-value = 0.661) as well as in the coronal plane (p-value = 0.219) at six month follow up. Both groups showed a similar rate of complication, most common being prominent hardware. TENS and SSENS are equally effective treatment modalities for paediatric femoral shaft fracture with similar rate of complications. However, SSENS is less costly as compared to TENS and can be considered as an alternative in a resource constrained setup.

Skeletal injuries following unintentional fall from height.

BACKGROUND: Falls from height are one of the leading causes of death from unintentional injuries. METHODS: We reviewed cases of musculoskeletal trauma due to fall from height, who were treated at a tertiary care hospital in Delhi over a one-year period, with respect to demographic data, site of accident, circumstances and location of fall, approximate height of fall, season, landing surface, details of skeletal and other injuries, and duration of hospital stay. RESULTS: Of 1451 admissions during the period, 138 were injured due to fall from height. Thirty-seven cases were excluded. The mean age of the patients was 31.3 years. The mean height of the fall was 4.54 meters (range: 0.6-12 meters). A total of 126 fractures occurred in 101 patients: 55 in the upper limbs, 50 in the lower limbs, 14 in the spine, and 7 in the pelvis. Associated injuries included head (n = 17), chest (n = 9) and abdominal injuries (n = 6). Ninety patients (89%) needed surgical intervention for fracture management. Eleven (10.8%) of these 101 injuries were fatal. CONCLUSION: Fall from height is a potentially preventable cause of skeletal injuries, as most of the injuries sustained due to fall from height were domestic injuries and occurred due to poor dwelling units.

Bone mineral density in young Indian adults with traumatic proximal femoral fractures. A case control study.

There is scarcity of data on osteoporosis in India for the age group of 20-40 years when peak bone mass is achieved. This study aimed to assess bone mineral density (BMD) in patients in this age group with traumatic proximal femoral fractures, and to compare it with age matched controls. Thirty patients aged 20 to 40 years with traumatic proximal femoral fractures and 30 healthy volunteers within the same age group were included in the study. Radiographs of the pelvis were taken to determine the Singh index, and DEXA scan of the unaffected hip was done to assess BMD. Fracture cases were compared with controls for significant difference in BMD. The male to female ratio of the study was 2:1. Based on Singh's index, 60% of fracture cases and 20% of controls were osteoporotic. T scores by DEXA revealed that 24 patients with fracture and 22 controls had osteopenia or osteoporosis. There was a significant difference in the Singh index between the two groups and no significant difference in BMD assessed by DEXA scan. No agreement was found between BMD determined by DEXA and Singh's index. The study points that our population fails to attain an adequate peak bone mass. It also questions the applicability of Western data to Indian population. The findings also indicate that Singh's Index cannot substitute DEXA for diagnosis of osteoporosis.
