Addressing posterior tilt displacement during surgery to lower failure risk of sub-capital Garden types 1 and 2 femoral fractures.

INTRODUCTION: Sub-capital femoral fractures (SCFF) are impacted or non-displaced in Garden types 1 and 2, respectively. Non-surgical treatment is protected weight-bearing combined with physiotherapy and radiographic follow-up in selected patients. Traditionally, in situ pinning is the surgical treatment of choice. The aim of this study was to estimate whether the valgus deformity in Garden types 1 and 2 (AO classification 31B1.1 and 31B1.2) SCFF is a virtual perception of a posterior tilt deformity and if addressing this deformity improves patients' outcomes. MATERIALS AND METHODS: The records of 96 patients with Garden Types 1 and 2 SCFF treated in tertiary medical center between 1/2014 and 9/2017 were retrospectively reviewed. They all had preoperative hip joint anteroposterior and lateral radiographic views. 75 patients had additional computed tomography (CT) scans. Femoral head displacement was measured on an anteroposterior and axial radiograph projections and were performed before and after surgery. Preoperative 3D reconstructions were performed for a better fracture characterization, and assessment of the imaging was performed by the first author. RESULTS: The average age of the study cohort was 73 years (range 28-96, 68% females). There were 58 right-sided and 38 left-sided fractures. Ninety patients had Type 1 and six patients had Type 2 fractures. The average preoperative posterior tilt was 15 degrees and the average valgus displacement was 10 degrees on plain radiographs compared to 28 degrees and 11 degrees, respectively, on CT scans. Posterior tilt was found with a virtual perception as valgus-impacted fractures. The postoperative posterior tilt was corrected to an average of 3 degrees and the valgus displacement to 5 degrees. CONCLUSION: CT provides an accurate modality for measuring femoral head displacement and fracture extent. The posterior tilt displacement should be addressed during surgery to lower failure risk and the need for additional procedures. IRB APPROVAL: TLV-0292-15. LEVEL OF EVIDENCE: IV.

Early versus delayed surgery for hip fragility fractures in patients treated with direct oral anticoagulants.

BACKGROUND: Delaying surgical treatment for hip fragility fractures increases mortality, but early intervention in patients treated with direct oral anticoagulant (DOAC) may increase the risk of perioperative blood loss due to residual drug activity. This study aimed to evaluate the effect of the timing of hip fragility fractures surgeries in patients treated with DOAC. METHODS: We retrospectively reviewed all records of DOAC-treated patients who underwent surgery for hip fragility fractures between 2011 and 2019. They were divided into three groups according to time to surgery since admission to the emergency room (ER), ≤ 24, 24-48, and ≥ 48 h. Blood loss, peri and postoperative complications, readmissions, and short- and long-term mortality were compared between groups. RESULTS: Of the 171 suitable patients (59 males and 112 females), 32 (18.7%) were in the ≤ 24 h group, 93 (54.4%) in the 24-48 h group, and 46 (26.9%) in the ≥ 48 h group. Timing of surgery did not affect blood loss, as indicated by changes in pre- and postoperative hemoglobin levels (p = 0.089) and proportion of perioperatively administered packed cells (p = 0.949). There was a trend towards increased 30-day mortality in the ≥ 48 h group compared to the 24-48 h and ≤ 24 h groups (13.0, 4.3 and 3.1%, respectively. p = 0.099), and a trend towards increased 90 day mortality (6.5, 3.2, and 0%, respectively. p = 0.298). CONCLUSIONS: Early surgery did not increase perioperative blood loss. Delayed surgery ≥ 48 h of patients receiving DOAC who underwent surgery for hip fragility fractures showed a trend towards increased 30 day and 90 day mortality.

Expandable Proximal Femoral Nail versus Gamma Proximal Femoral Nail for the treatment of hip reverse oblique fractures.

BACKGROUND: Reverse oblique intertrochanteric fractures are classified by the AO/OTA as 31A3 and account for 2-23% of all trochanteric fractures. The Gamma 3-Proximal Femoral Nail (GPFN) and the Expendable Proximal Femoral Nail (EPFN) are among the various devises used to treat this fracture. The aim of this study was to compare outcomes and complication rates in patients with AO/OTA 31A1-3 fractures, treated by either a GPFN or an EPFN. PATIENTS AND METHODS: A total of 67 patients (40 in the GPFN group and 27 in the EPFN group, average age 78.8 years) were treated in our institution between July 2008 and February 2016. Data on postoperative radiological variables, including peg location and tip-apex distance (TAD), as well as orthopedic complications, such as union rate, surgical wound infection and cut-outs rates were also recorded, along with the incidence of non-orthopedic complications and more surgical data. Functional results were evaluated and quantified using the Modified Harris Hip Score (MHHS) and by the Short Form 12 Mental Health Composite questionnaire (SF-12 MHC) in order to assess the quality of life. RESULTS: The total prevalence of postoperative orthopedic complications including postoperative infection showed a significant difference with a p-value of 0.016 in favor of the EPFN group. Nonetheless, the frequency of revision did not differ between the two groups, being 0.134. The main orthopedic complication in both groups was head cut-out of the GPFN lag screw and the EPFN expendable peg, which was 20% and 7.4%, respectively, and required a revision surgery using a long nail or total hip replacement (THR). However, the average TAD did not significantly differ between groups which might be due to a relatively low cohort to reach a significant difference. Nonunion rate of 5% occurred solely in the GPFN group, with similar results of intraoperative open reduction between both groups. The EPFN group achieved better scores in both questionnaires (p = 0.027 and p = 0.046, respectively). Both the MHHS and SF-12 MCS values significantly differed between groups, with the EPFN group achieving better scores than the GPFN group in both questionnaires (p = 0.027 and p < 0.05, respectively). CONCLUSIONS: According to this study, the EPFN yields better results in comparison with the GPFN, with relatively less complications rate, for the treatment of unstable reverse oblique pertrochanteric fracture. In light of this results, we conclude that the EPFN might be as good as GPFN for the treatment of reverse oblique intertrochanteric fractures. LEVEL OF EVIDENCE: Level III retrospective study. The local institutional review board of the Tel Aviv Medical Center approved this study and all the surgeries were done exclusively in this institution.

Adding a First Metatarsal Pin to An Ankle Tubular External Fixator Does Not Reduce the Incidence of Early Reduction Loss.

External fixation with a bilateral frame configuration (delta frame, DF) is a routine approach for treating ankle fractures and dislocations with severe soft tissue damage. The purpose of this study was to evaluate to what extent adding a first metatarsal fixation contributes to the stability of the fixation as evidenced by reduced frequency of early loss of reduction. A retrospective study was performed to compare the rate of early reduction loss in patients treated with a bilateral frame external fixation as part of a 2-stage treatment protocol for periarticular ankle fractures, in a level one trauma center between 2006 and 2016. The cohort was divided into 2 groups according to the frame configuration that had been used: DF only and DF with first metatarsal fixation (DF+1MT). A multivariate analysis assessing risk factors for postoperative loss of reduction was conducted. A total of 67 patients were included in the study, of which 30 underwent fixation by DF and 37 by DF+1MT. Early loss of reduction was recorded in 13 (19.4%) patients, 6 (20%) in the DF group and 7 (18.9%) in the DF+1MT group (p = .576). None of the assessed risk factors reached statistical significance. To conclude, the addition of a first metatarsal pin as an enhancement of external fixation with a delta frame configuration did not reduce the incidence of early loss of reduction. There is no evidence to support the claim that adding this pin contributes to the stability of the fixation in a clinically relevant manner.

Functional outcomes after removal of hardware in patellar fracture: are we helping our patients?

PURPOSE: Functional outcomes after Open Reduction Internal Fixation (ORIF) of the patella are variable. Common complications of patella ORIF include persistent anterior knee pain, limited range of motion and symptomatic hardware. The purpose of this study was to evaluate if removal of hardware is beneficial to symptomatic patients after patellar fracture fixation. METHODS: Patients who presented to our institution between December 2006 and November 2014 with patella fractures treated with ORIF were eligible for inclusion. Patella ORIF was performed using (1) K-wires (KW) with a tension band construct or (2) Cannulated Screws (CS) with a tension band construct. Radiological analyses included (1) AO classification and (2) measurements of prominent hardware length. Patient medical charts were reviewed for demographic and intraoperative data as well as peri/postoperative complications. All patients completed the SF-12 score, visual analog scale, Kujala score, Lysholm score and questionaries' regarding return to previous activity levels. RESULTS: Forty-seven patients met the inclusion criteria. The average time from fracture fixation to removal of hardware was 15.8 (SD ± 14.9) months. The mean follow-up was 43.1 (SD ± 27.1) months. Patella fixation was accomplished using tension band constructs with KW in 28 patients (59.5%) or with CS in 19 patients (40.5%). Patient reported quality of life and pain outcomes improved significantly after removal of hardware (p = 0.001, and p = 0.002 respectively). Functional outcome scores (Kujala and Lysholm) did not improve significantly after hardware removal in the KW or CS groups. Significantly more patients in the KW group returned to pre-injury activity (p = 0.005). CONCLUSIONS: Hardware removal after patella ORIF significantly improves patient reported pain and quality of life outcomes but not functional outcomes. Patients should be counseled regarding the expected outcome of hardware removal following patella ORIF and diabetic patients should be given special consideration before undergoing this procedure.

Corona mortis anastomosis: a three-dimensional computerized tomographic angiographic study.

PURPOSE: We evaluated the corona mortis (CM) anatomy by means of three-dimensional computerized tomography angiographic (CTA). METHODS: Patient demographic, anastomosis incidence, artery diameter, artery distance from the symphysis pubis, and pelvic size (distance between both acetabular upper labrum) parameters were assessed. The 100 patients included 66 males and 34 females (average age of 67.8 years). RESULTS: There were 66 (33%) arterial anastomoses in the 200 evaluated arteries, 30 in the right side and 36 in the left side, 36 unilaterally and 15 bilaterally. No anastomoses were detected in 49 patients. The average diameter was 2.4 mm for the right-sided arteries and 2.24 in the left-sided ones. The distance was 55.2 mm from the right symphysis and 57.2 from the left symphysis (greater for females, 62.2 versus 55.85 mm [p = 0.037] only on the left side). The artery disappears in smaller-sized pelvises. There was a non-occluded arterial pattern in 47 (71%) and a partially occluded one in 19 (29%, all with peripheral vascular disease). CONCLUSION: One-third of the evaluated CTAs revealed competent CMs. CMs were more lateral in females than in males and were absent in small-sized pelvises. It is highly recommended that the radiologist and the surgeon should be familiar with CM existence for decision-making with regard to emergency radiology imaging and intervention as well as when operating in proximity of that anatomic site.

Preoperative Planning of Orthopedic Procedures using Digitalized Software Systems.

The progression from standard celluloid films to digitalized technology led to the development of new software programs to fulfill the needs of preoperative planning. We describe here preoperative digitalized programs and the variety of conditions for which those programs can be used to facilitate preparation for surgery. A PubMed search using the keywords "digitalized software programs," "preoperative planning" and "total joint arthroplasty" was performed for all studies regarding preoperative planning of orthopedic procedures that were published from 1989 to 2014 in English. Digitalized software programs are enabled to import and export all picture archiving communication system (PACS) files (i.e., X-rays, computerized tomograms, magnetic resonance images) from either the local working station or from any remote PACS. Two-dimension (2D) and 3D CT scans were found to be reliable tools with a high preoperative predicting accuracy for implants. The short learning curve, user-friendly features, accurate prediction of implant size, decreased implant stocks and low-cost maintenance makes digitalized software programs an attractive tool in preoperative planning of total joint replacement, fracture fixation, limb deformity repair and pediatric skeletal disorders.

Anchor suture fixation of distal pole fractures of patella: twenty seven cases and comparison to partial patellectomy.

PURPOSE: Partial patellectomy (PP) and reattachment of the patellar ligament with transosseous suturing is the mainstay of surgical treatment for distal pole patellar fractures. An anchor suturing (AS) technique has recently been reported as an alternative to PP in such fractures and allows for bone-to-bone interface and possibly superior fracture healing than bone-to-tendon interface with PP. We present our experience with AS and compare it to PP. METHODS: Between 2006 and 2011, 60 patients with distal pole patellar fracture underwent either AS (n = 27) or PP (n = 33). We retrospectively gathered their demographic data and information on fracture type, fixation technique, operation time, postoperative complications and knee range of motion. A telephone survey was performed to grade functional outcomes with standard questionnaires (the SF-12 for quality of life, the Kujala score for patellofemoral function and a visual analog scale [VAS] pain score). RESULTS: AS was equivalent to PP in terms of residual pain and functional outcomes (VAS: 2.45 vs. 2.26, p = 0.83 and Kujala score: 74.3 vs. 69, p = 0.351, respectively) as well as for knee range of motion. Complications included three cases of infection in each group, two cases of early hardware failure and one case of non-union in the AS group. Operation time was significantly shorter for AS compared to PP (68.5 vs. 79.1 min, p = 0.03). CONCLUSIONS: AS is non-inferior to PP for function and pain after distal pole patellar fractures and is superior to PP with regard to operative time. Common complications of this technique are hardware failure and infections. LEVEL OF EVIDENCE: Therapeutic Level III.

Capsular closure does not affect development of heterotopic ossification after hip arthroscopy.

PURPOSE: The purpose of this study was to evaluate the role of capsular closure after hip arthroscopy in reduction of the incidence of heterotopic ossification (HO). METHODS: One hundred (50 study group, 50 control group) consecutive hip arthroscopy procedures with radiographic follow-up of more than 9 weeks were included in the study. The study group consisted of 50 patients in whom capsular closure with 2 No. 1 polydioxanone (PDS) sutures was performed, and a control group consisted of 50 patients in whom the capsule remained open after capsulotomy. HO was assessed by radiographs using the Brooker classification. Statistical analysis of the data was carried out with the χ-square or Fisher exact test and Student t test, when appropriate, at a significance level of .05. RESULTS: Thirty-six (36%) patients had radiographic evidence of postoperative HO (14 patients in the capsular closure group). No significant difference was found regarding sex, side of operation, age, or HO rate between the study and the control groups (P = .778, P = .123, P = .744, and P = .144, respectively). Furthermore, no significant difference was found in the rate of HO with potential clinical significance (Brooker classification > I) between the control and study groups (P = .764). CONCLUSIONS: Capsular closure did not seem to alter the rate of HO when compared with a control group of patients in whom the capsulotomy was not repaired. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Predictors for nonunion, reoperation and infection after surgical fixation of patellar fracture.

INTRODUCTION: The most common major complications following surgical fixation of patellar fractures are infection, nonunion and reoperation. In this study, we sought to define the predisposing factors to the development of these complications. METHODS: Open reduction and internal fixation surgeries for patellar fractures that were performed in a single institution between 2006 and 2011 were retrospectively reviewed. Patients' demographic data (age, gender, comorbidities), injury and fracture data (associated injuries, type of fracture, open or closed fracture), surgical data (type of surgery and interval between fracture occurrence and surgery) and major postoperative complications (infection, nonunion, symptomatic hardware and revision surgery) were collected from the medical records and verified by a telephone survey. Correlation analysis identified the major variables influencing the development of these complications. RESULTS: The cohort of 188 patients had an average follow-up of 908 days. Thirteen (6.9 %) patients developed infection, 3 (1.6 %) had fracture nonunion and 42 (22.3 %) required a second operation. A history of cerebrovascular accident (CVA) correlated significantly with the development of infection (OR 6.18, CI 1.1-35.6, p = 0.041) and nonunion (OR 14.9, CI 1.2-188.1; p = 0.037). A history of diabetes significantly increased the risk of a second operation (OR 8.69, CI 95 % 1.8-41.9, p = 0.007). Open fracture did not increase the risk of any of these complications. CONCLUSIONS: A history of CVA and diabetes mellitus significantly increased the risk of complications following patellar fracture fixation. Patients with these comorbidities should be informed of their increased risk of these complications and be followed up more rigorously.

Long-Term Outcomes Following Reduction and Fixation of Displaced Subcapital Hip Fractures in the Young Elderly.

BACKGROUND: The surgical treatment of hip fractures remains controversial especially when considering age. OBJECTIVES: To investigate the long-term functional outcomes of displaced subcapital hip fractures that were reduced and surgically fixed using parallel cannulated screws in patients aged 60 years and younger. METHODS: During the period 1996-2005, 27 patients under age 60 with displaced subcapital hip fractures classified as Garden III or IV were treated with fracture reduction and surgical internal fixation using cannulated screws. Patient outcomes were assessed using the Harris Hip Score (HHS) and physical examination. RESULTS: During a follow-up period of 8-17 years 4 of the 27 patients (14.8%) developed non-union/femoral head avascular necrosis and had undergone hip arthroplasty. All reoperations were performed within the first year after fracture fixation, all in the 50-60 year old age group. The revision rate among patients 50-60 years old was significantly higher than that of patients 50 years and younger (40% vs. 0%, P = 0.037). Mean HHS was higher for patients not requiring revision surgery (85.4) than for patients with revision surgery (75.5), but this difference was not significant. CONCLUSIONS: Internal fixation using fracture reduction and cannulated screw fixation is a successful treatment modality for displaced subcapital hip fractures in patients under 50 years old. Patients aged 50-60 may have a higher risk of avascular necrosis or non-union and require arthroplasty, often within the first year after fracture fixation. The long-term outcome following these fractures is good when excluding patients who had early complications.

Gait characteristics and quality of life perception of patients following tibial plateau fracture.

INTRODUCTION: The purpose of the current study was to evaluate the long-term functional outcome as measured by gait patterns and quality of life assessment of patients with high-energy tibial plateau fracture compared to matched controls. MATERIALS AND METHODS: Thirty-eight patients were evaluated in a case-controlled comparison. Twenty-two patients with tibial plateau fracture were evaluated after 3.1 (1.63) years (sd) from injury. Patients underwent a computerized spatiotemporal gait test and completed the SF-12 health survey. 16 healthy subjects, matched for age and gender served as a control group. The main outcome measures for this study were spatiotemporal gait characteristics, physical quality of life and mental quality of life. RESULTS: Significant differences were found in all gait parameters between patients with tibial plateau fracture and healthy controls. Patients with tibial plateau fracture walked slower by 18% compared to the control group (p < 0.001), had slower cadence by 8% compared (p = 0.002) to the control group and had shorter step length in the involved leg by 11% and in the uninvolved leg by 12% compared to the control group (p = 0.006 and p = 0.003, respectively). Patients with tibial plateau fracture also showed shorter single limb support (SLS) in the involved leg by 12% compared to the uninvolved leg and 5% in the uninvolved leg compared to the control group (p < 0.001 and p = 0.017, respectively). Significant differences were found in the Short Form (SF)-12 scores. Physical Health Score of patients with tibial plateau fracture was 65% lower compared to healthy controls (p < 0.001), and Mental Health Score of the patients was 40% lower compared to healthy controls (p < 0.001). Finally, significant correlations were found between SF-12 and gait patterns. CONCLUSION: Long-term deviations in gait and quality of life exist in patients following tibial plateau fracture. Patients following tibial plateau fracture present altered spatiotemporal gait patterns compared to healthy controls, as well as self-reported quality of life.

Clinical and functional outcome after acetabular labral repair in patients aged older than 50 years.

PURPOSE: To assess the clinical and functional outcome of labral repair in patients aged older than 50 years. METHODS: We performed a prospective analysis of 20 patients aged older than 50 years who had undergone arthroscopic repair of a torn acetabular labrum (6 men and 14 women; mean age, 58 years). The indication for surgery was groin pain due to various causes with or without associated mechanical symptoms that did not respond to nonoperative treatment for more than 6 months. Intraoperatively, all patients were diagnosed with labral pathology. The mean duration of symptoms was 3.1 years (range, 0.5 to 15 years). The mean follow-up period was 22 months (range, 12 to 35 months). The outcome was prospectively measured with the modified Harris Hip Score (MHHS) and Hip Outcome Score (HOS). RESULTS: The indication for surgery was femoroacetabular impingement (FAI) with cam deformity and a labral tear in 4 patients, FAI with pincer deformity and a labral tear in 1 patient, FAI with both deformities in 1 patient, a gluteus medius tear in 2 patients, and an isolated labral tear in 12 patients. Acetabular chondral lesions were present in 11 patients (55%). The mean preoperative and postoperative MHHS was 62.5 and 87.2, respectively (P < .001); the mean preoperative and postoperative HOS was 42.7 and 86.3, respectively (P < .001); and the mean preoperative and postoperative level of function during usual activities of daily living according to the HOS was 46.0% and 73.7%, respectively (P < .001). No significant difference was identified in MHHS and HOS between gender groups. CONCLUSIONS: Arthroscopic management of FAI and labral repair in patients aged older than 50 years without significant arthritis (Tönnis grade 1 or better) are associated with significant improvement in outcome. Because of the potential importance of the labrum for long-term hip joint integrity, we advocate repair of the labrum in patients aged older than 50 years when possible. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Transient sternoclavicular joint arthropathy, a self-limited disease.

BACKGROUND: The sternoclavicular joint (SCJ) is a true diarthrodial synovial joint and therefore vulnerable to the same disease processes as in other synovial joints. We identified a group of patients with monarticular arthritis of the SCJ that had a benign process and a self-limited disease course. METHODS: This retrospective study included 25 female patients who presented with pain or swelling of the SCJ between January 2000 and December 2010. Their mean age was 59 years, and the average follow-up was 44 months. All patients underwent baseline radiographic imaging, technetium bone scan, computed tomography, and magnetic resonance imaging. Blood profiles were negative for rheumatoid factor in all patients. Functional outcome was assessed with the Rockwood SCJ score. RESULTS: The patients presented with complaints of pain (72%), local swelling (88%), and redness (8%) that progressed during 4 weeks. The physical examination revealed tenderness (84%), swelling (88%), and limited range of motion (16%). These findings persisted for a median of 5 months. Plain radiographs showed arthritic changes in 5 patients (20%). Increased uptake was observed in all 9 patients who underwent a bone scan. Soft tissue swelling was demonstrated on computed tomography in 5 patients (20%) and on magnetic resonance imaging in 5 patients (20%). One patient had osteoarthritic changes on magnetic resonance imaging. Pain resolved spontaneously in all patients, leaving only swelling in 9 patients and tenderness in 1 patient. CONCLUSION: Our experience is that SCJ arthropathy may often be a self-limited disease. After being treated solely with nonsteroidal anti-inflammatory medication, 24 of the 25 study patients showed complete regression of pain and return to full function without recurrence of symptoms. Basic blood tests and radiographs are sufficient to rule out a septic joint.

Early operative intervention is associated with better patient survival in patients with intracapsular femur fractures but not extracapsular fractures.

The purpose of this study was to determine patients' survival after undergoing an early or delayed operation. We retrospectively assessed 1849 files of patients operated for proximal femoral fracture, divided into two diagnostic groups: intracapsular (n = 640) and extracapsular (n = 1209). 1163 (63%) were treated within 48 h from hospital admission and 686 (37%) were treated >48 h afterwards. Delayed operation in patients with intracapsular fractures was associated with a 1.8-fold excess risk for 1-year mortality (HR = 1.83, P = 0.008), while no effect was observed for patients with extracapsular fractures. Males had a higher HR for mortality in both diagnostic groups. Early surgical intervention is beneficial for intra-capsular femoral fractures; male gender and a high ASA score are associated with an increased mortality hazard risk.

Predicting the need for blood transfusion in patients with hip fractures.

PURPOSE: The need for perioperative blood management measures aimed at improving patient outcomes and reducing allogenic blood transfusion (ABT) is increasingly recognised. Our study aim is to create an algorithm to predict and manage the need for blood transfusion in patients with hip fractures. METHODS: We retrospectively assessed 1,484 patients with hip fractures and analysed the probability of receiving an ABT within 72 hours of admission. Univariate, multiple logistic regression analysis and a probability algorithm for predicting the need for blood transfusion on the basis of independent multivariate predictors were used. RESULTS: Significant predictors for ABT were: older age; lower haemoglobin on admission; female gender; type of surgical implant (cephalomedullary nail and dynamic hip screw more than hemiarthroplasty); and a shorter wait time from admission to surgery. A regression model algorithm correctly predicted the need for an ABT in 73 % of the cases. CONCLUSION: An algorithm and a simple clinical tool were devised to predict and manage the need for a blood transfusion within 72 hours of admission in patients with hip fractures.

Sequelae of underdiagnosed foot compartment syndrome after calcaneal fractures.

The calcaneus is the most frequently fractured tarsal bone. Compartment syndrome (CS) complicates fractures and other injuries and is most commonly described in association with the lower leg. The long-term sequelae of CS of the foot can include toe clawing, permanent loss of function, persistent pain, muscle atrophy, contracture, painful warts, weakness, and sensory disturbances. The incidence and clinical significance of untreated CS after calcaneal fractures were questioned. All compliant patients treated by us for a calcaneus fracture underwent a physical examination and medical interview: 47 (49 fractures) were included in the final cohort (36 males, 11 females, mean age 49 ± 14.5 years, mean follow-up 23 ± 16 months). Missed CS sequelae were diagnosed by the presence of claw toes and plantar sensory deficits. The functional outcome and pain at rest and during activity were scored. Five patients (10%) had missed CS, and their functional score was significantly lower than for those without CS (52 ± 21.5 versus 77.4 ± 22 for no CS, p < .05). All missed CS cases were diagnosed in patients with a Sanders type 3 or 4 fracture. Intra-articular fracture was a significant factor associated with developing CS sequelae (p = .045). Untreated CS can cause muscle and nerve injury and contribute to a poor functional outcome. Because CS is more likely to develop after highly comminuted intra-articular fractures, these patients warrant close monitoring for CS development. Early detection and treatment might result in fewer late disabling sequelae of this injury.

Efficacy of Oral Nutritional Supplements in Patients Undergoing Surgical Intervention for Hip Fracture.

Introduction: Malnutrition is considered a risk factor among geriatric individuals with hip fracture, affecting functional healing and recovery, increasing healthcare spending, and associated with high mortality. In this study, we sought to evaluate the clinical efficacy of oral nutritional supplements in geriatric patients undergoing surgery for hip fracture. Material and Methods: We retrospectively analyzed data of 1625 consecutive patients who underwent fixation or arthroplasty for hip fracture in a tertiary medical center between 2017 and 2020. Patients who had no available albumin or body mass index levels were excluded. The study group is of patients who received an advanced formula in the form of an oral nutritional supplement (ONS), and the control group of patients that received no ONS. Peri- and postoperative complications, readmissions, short-term mortality, and albumin levels were compared between the 2 groups. Results: The final cohort included 1123 patients, 298 in the study group and 825 controls, with a follow-up of at least 1-year. Provision of the advanced enriched formula was not associated with 30-day, 90-day, or 1-year mortality (P = .62, P = .52, and P = .72, respectively) or any perioperative complications, such as 30-day or 90-day readmission (P = .37 and P = .1, respectively), revision surgery of any cause (P = .35), and postoperative infection rates (P = .73). Albumin levels on admission and the minimum albumin levels during hospitalization were similar between the groups, but they were significantly higher in the study group before discharge (33.42 g/L vs. 32.79 g/L, P = .01). Discussion: The use of an ONS was not associated with reduced perioperative complications or mortality, although it did affect nutritional status, as indicated by increased albumin levels, a known marker of nutritional status. Conclusions. While current findings do not support ONS use to minimize major postoperative complication after hip fracture surgery, further long-term study is warranted to evaluate subjective and functional outcomes associated with improved nutritional status.

Rethinking Conservative Treatment of Humeral Diaphyseal Fractures in Elderly Patients With Dementia.

OBJECTIVES: To assess outcomes and complications of conservatively managed humeral diaphyseal fractures in elderly patients, with an emphasis on the subgroup diagnosed with dementia. DESIGN: Retrospective. SETTING: Upper extremity surgery unit at an academic Level I trauma center. PATIENTS/PARTICIPANTS: Consecutive patients 65 years of age and older who were managed conservatively for humeral diaphyseal fractures between 2007 and 2015. INTERVENTION: Conservatively managed humeral diaphyseal fractures. MAIN OUTCOME MEASUREMENTS: Complications and radiographic outcomes. RESULTS: One-hundred twenty-four patients who were conservatively managed for humeral diaphyseal fractures were identified. Their mean age was 77 (65-92) years, 36 (30%) of them were male and 88 (70%) were female. Fifty-seven (46%) patients experienced complications associated with their treatment, and 33 (27%) patients were eventually treated surgically. Seventeen (14%) patients were diagnosed with dementia. This subgroup had 64% fracture-related complications, and all of them were operated (P-value <0.01 compared with age-matched patients among the other 107 participants in the study). CONCLUSION: Conservative management of humeral diaphyseal fractures seems to be associated with greater morbidity in elderly patients, especially in those diagnosed with dementia. Therefore, early surgical treatment should be considered. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Early results of retrograde expandable nail fixation of 29 distal femoral fractures.

The authors retrospectively reviewed 27 consecutive patients with 29 fractures of the distal femur treated with the new retrograde expandable nail. One 10-mm diameter nail that expands to 16 mm was used with the possibility of locking in the condylar area only. Retrieved data included single versus multiple injuries, fracture type, operation time, reaming or nonreaming, hospitalization and healing times, and intra- and postoperative complications. The overall average operation time was 96 (range 40-320) minutes, but only 65 (range 40-120) minutes for isolated fractures. The overall mean hospitalization time was 16 (range 3-40) days, but only 7 (range 4-10) days for isolated fractures. Follow-up continued until fracture healing or for a minimum of 1 year (average 14 months, range 12-24 months). The average clinical union time was 83 (range 43-179) days, and the mean radiographic healing was 87 (range 43-179) days. One patient developed a nonunion that required exchange of the nail to the same device. Another patient underwent hardware removal during a procedure for a torn meniscus. These preliminary results demonstrate satisfactory healing and alignment for the treatment of distal femoral shaft fractures by means of this new device without jeopardizing the knee joint by nail protrusion.
