Acute kidney injury after hip fracture surgery in patients over 80 years of age.

BACKGROUND: The aim of the study is to determine the rate of acute kidney injury (AKI) after hip fracture surgery over the age of 80 and to investigate the factors associated with AKI. METHODS: From January 2015 to January 2020, 589 patients who underwent surgery of hip fractures at our institution were retrospectively reviewed. Serum creatinine (sCr) was analysed daily pre- and postoperatively during the hospital stay. Patients were divided into groups; AKI and non-AKI based on KDIGO (Kidney Disease Global Outcomes) criteria. The incidence, risk factors, and mortality of postoperative AKI were investigated. RESULTS: Out of 589 patients, 58 developed an AKI (9.8%). Smoking (p: 0.004), pre and postoperative low albumin level (p < 0.05), pre- and postoperative high potassium level (p < 0.05), pre- and postoperative high urea levels (p < 0.05), high amount of intra-operative bleeding (p: 0.003) and prolonged surgery time (p: 0.003) were found to be risk factors associated with AKI. Although the mortality rate was higher in the AKI group, it was not statistically significant (p > 0.05). CONCLUSION: AKI is a temporary but common complication following hip fracture surgery, which can also be predicted if risk factors are adequately observed. It typically increases the length of hospital stays, mortality and morbidity. LEVEL OF EVIDENCE: Level III evidence, Retrospective comparative study.

Does low body mass index constitute a risk of damage to the soft tissues during reaming for proximal femoral nailing? a cadaveric study.

BACKGROUND: The purpose of this cadaveric study was to evaluate the damage to the gluteus medius muscle, tendon and superior gluteal nerve in low BMI patients during the reaming of the greater trochanter tip for proximal femoral nailing. MATERIALS AND METHODS: The study used 19 femurs of 10 fresh femur intact cadavers [mean BMI: 22.79 (17.60-28.70)]. A guidewire was placed in the tip of greater trochanter under C-arm fluoroscopy, and a 17-mm reamer was advanced over the wire. After the reaming was completed, the hips were dissected and the gluteus medius muscle, tendon and superior gluteal nerve were inspected to evaluate the amount of injury. RESULTS: BMI was < 18.50 in 3 cadavers. The gluteus medius muscle was injured in all hips. The superior gluteal nerve was intact in all hips, but the thickness of gluteus medius muscle mass that remained intact was thicker in the cadavers with a higher BMI (3.86 mm for low BMI, 9.08 mm for high BMI group). The percentage of the tendon insertion disrupted by the reamer was an average of 36.20% in the low BMI group and an average of 26.93% in the high BMI group. The percentage of the tendon insertion disrupted by the reamer showed a statistically significant difference between low and high BMI cadavers. CONCLUSION: The injury to the gluteus medius muscle and tendon after proximal femoral nailing through the greater trochanter tip may be higher in patients with low BMI. It must be kept in mind that gluteal muscle could be damaged during proximal femoral nailing and this could result in limping.

Does computerized tomography change the treatment decision in pediatric medial epicondyle fractures?

The amount of displacement in medial epicondylar fracture is one of the most important criteria for treatment decision. The displacement of medial epicondyle fractures of the humerus may be underestimated by standard AP and lateral views of elbow. The aim of the current study is to show the clinical relavance of computerized tomography (CT) for medial epicondyle fractures. A retrospective analysis on patients with medial epicondyle fracture was performed. Measurements were performed by 9 reviewer, there were 12 cases available for review with both radiographs and CT. The difference between measurement of AP Xray versus frontal and axial CT scans was found to be statistically significant for 1st and 2nd assessments (p=0.001). The decision for operative treatment was higher after evaluation with CT for both first and second assessment and this was statistically significant (p=0,0001). CT is found to be superior to determine the real amount of the fracture displacement and was relavant for treatment decision of pediatric medial epicondylar fractures. We also found a better interobserver agreement for axial CT scans relative to treatment decision. Level of evidence : IV.

The Results of Physical, Radiologic, Pedabarographic, and Quality-of-Life Assessments in Patients with Surgically Treated Intraarticular Calcaneus Fractures.

Calcaneal fractures are complex injuries and have historically had a poor prognosis that results in substantial disability. However, no studies have been performed that analyze both the radiographic and plantar pressure changes after treatment of intraarticular calcaneus fracture. Patients with an intrarticular calcaneus fracture treated at our institution during the study period were identified from computerized hospital records. A total of 36 patients (34 males) completed physical examination and radiographic and dynamic pedobarographic assessments. The follow-up period was from 13 to 82 months (median 38 months). The mean pain score at rest was 3.7 and during activity was 4.0 on a 10-cm visual analogue scale. The mean range of motion of the subtalar joint was restricted. The mean American Orthopaedic Foot and Ankle Society function scale score was 68.1; the mean Short Form-36 physical score was 41.8; and the mental score was 44.9. Pedabarographic results showed that the mean maximum force in the midfoot, forefoot, and toes (p = .001; p = .04; p = .002) and peak pressure in the midfoot, forefoot (p = .001; p = .007), and contact area of the midfoot and toes (p = .038; p = .004) were significantly increased in the injured foot. Radiologic findings showed hindfoot varus, forefoot adductus, and an increase in the medial arch. Even after appropriate anatomic realignment with open reduction and internal fixation of calcaneus fractures, residual differences in plantar pressures and radiographic measures are noted compared to uninjured foot.

USG-guided injection of corticosteroid for lateral epicondylitis does not improve clinical outcomes: a prospective randomised study.

BACKGROUND: Corticosteroid injection used to be the treatment of choice for lateral epicondylitis. Most injections are performed blindly. In the blinded technique, it could be difficult to determine the exact pathological localisation. The purpose of this single-blinded, randomised controlled clinical study was to compare the clinical therapeutic effects of blinded and USG-guided corticosteroid injection therapy in lateral epicondylitis. PATIENTS AND METHODS: Forty patients with chronic lateral epicondylitis were included in this clinical trial. The patients were randomly allocated to blinded group or USG-guided injection group according to a computer-generated randomisation list. All blinded injections were administered by an orthopaedic surgeon and all ultrasound-guided injections were made by a radiologist experienced in this technique. All patients were injected under aseptic conditions using 40 mg/2 mL methylprednisolone acetate. The outcomes of both treatments were assessed by an independent assessor at pre-injection, then at 6-week and 3- and 6-month follow-up assessments. The assessor evaluated the q-DASH, VAS, and grip strength scores. RESULTS: No statistically significant difference was determined between the groups in respect of the Q-DASH and grip strength scores preoperatively and at 6 weeks and 3 and 6 months post-injection. No statistically significant difference was determined between the groups in respect of the VAS scores preoperatively and at 6 weeks and 6 months. No systemic or local complications were reported during the treatment. CONCLUSION: There was no statistically significant difference compared to the blinded injection technique, and the mean score differences between the groups are of no clinical relevance.

Endoscopic Plantar Fasciotomy; Deep Fascial Versus Superficial Fascial Approach: A Prospective Randomized Study.

In the present randomized prospective study, 2 different surgical techniques of endoscopic plantar fascia release were compared. Of 547 patients with a diagnosis of plantar fasciitis, 46 with no response to conservative treatment for ≥6 months were included. Of the 46 patients, 5 were lost to follow-up. In group 1 (n = 21), plantar fascia release was performed using a deep fascial approach (DFA), and in group 2 (n = 20), the superficial fascial approach (SFA) with a slotted cannula technique was used. Patients were evaluated using the American Orthopaedic Foot and Ankle Society Ankle Hindfoot scale and visual analog scale at baseline and 3 weeks and 3, 6, and 12 months after the initial surgery. At the final follow-up appointment, the Roles-Maudsley score was used to determine patient satisfaction. At the final follow-up examination, the mean American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale scores had increased from 53.12 to 83.68, with a decrease in the mean visual analog scale score from 7.95 to 1.65 noted. According to the Roles-Maudsley score, the success rate after 1 year was 90.47% for DFA group, 95% for the SFA group, and 92.68% for all patients. Although no significant difference was found between the final functional scores, better early postoperative scores were found in the SFA group. The mean duration of the procedure was measured as 27.22 ± 9.41 minutes overall, 35 ± 5.62 minutes in the DFA group, and 19.05 ± 4.01 minutes in the SFA group. Two early and two late complications occurred in the DFA group with none reported in the SFA group. In conclusion, the SFA is a faster and safer method of endoscopic plantar fascia release with better early postoperative scores.

Computerized tomography imaging in adolescent idiopathic scoliosis: prone versus supine.

BACKGROUND: The aim of the present study was to assess the degree of apical vertebral rotation values in Adolescent Idiopathic Scoliosis (AIS) that were obtained on CT scans, and to analyze the influence of patient position (supine versus prone) on the degree of rotation. METHODS: The study included 50 apical vertebra rotation measurements of 34 patients with Type 1A and Type 3C curvature according to the Lenke classification. CT imaging was applied to the patients in supine and prone positions to measure the apical vertebral rotation (AVR). The average AVR angles were measured using the Aaro-Dahlborn method and the results were compared. RESULTS: No significant differences were found between the vertebral rotation measured in the prone and supine positions for the Lenke 1A subgroup and the Lenke 3C thoracic group (p = 0.848; p = 0.659, respectively). In the Lenke 3C lumbar group, however, the vertebral rotation in the supine position was found to be significantly lesser than that in the prone position (difference -1.40° ± 1.79°, p = 0.007). CONCLUSION: The assessment of the apical vertebra rotation is crucial in AIS. Even though the vertebral rotation in the supine position was found to be significantly lesser than that in the prone position, CT imaging in a prone position could not be considered clinically more relevant than the CT images in a supine position as there was less than 3° difference.

Is internal fixation of the intertrochanteric fractures reliable option in patients with cognitive dysfunction?

The purpose of this study was to compare the results of hemiarthroplasty with those of treatment internal fixation devices for stable intertrochanteric fractures in patients with moderate and severe cognitive dysfunction. 155 patients were evaluated retrospectively. 54 patients were treated with proximal femoral nail (PFN), 57 with dynamic hip screw (DHS) and 44 were underwent hemiarthroplasty (HA). Activities of daily living (ADL) were evaluated with the Barthel Activity Index (BI) score and the Health Related Quality of Life (HRQoL) with the Euroquol-5D (EQ-5D) test. The BI scores in HA patients were found to be at significantly high compared to the PFN and DHS groups both at the one and two years. A significant difference was also found in the EQ-5D scores in favor of HA group at one year. The most common complications in internal fixation patients were malunion (7/54 for PFN, 9/57 for DHS group), fixation failure (8/54 for PFN, 12/57 for DHS group) and dislocation (10/44), deep infection (8/44) for HA group. The strong predictive variables on ADL in dementia patients were, duration time to surgery and pre-operative MMSE score. In conclusion, HA is the prefered treatment for stable intertrochanteric fractures but that the dislocation (10/44) and infection rates (8/44) are very high in dementia.

The effect of amputation level and age on outcome: an analysis of 135 amputees.

INTRODUCTION: In this retrospective study, the impact of age, amputation level and the cause of amputation were examined using the Hospital Anxiety and Depression Scale (HADS) and Medicare K scores of amputees with unilateral lower-limb amputation. MATERIALS AND METHODS: In total, 135 patients with unilateral transfemoral (TF) or (TT) transtibial amputations were examined. All data were collected using questionnaires that were either self-administered or administered during an interview. The HADS was developed as a self-reporting questionnaire to detect adverse anxiety and depressive status. K code is used to describe the functional abilities of amputees. RESULTS: The mean age at the time of surgery was 52.79 ± 13.08 years. The mean time since amputation was 59.20 ± 24.41 months for TT, and 60.89 ± 22.09 months for TF amputation. The HADS-A scores of the transfemoral amputation group were determined as significantly high compared to those of the transtibial group (p < 0.05). The K index of the group aged 35 years and below was significantly higher than that of the other groups (p 0.002, p 0.001, p < 0.01). CONCLUSION: The data show higher HADS-A scores with traumatic transfemoral amputation. Therefore, adequate psychiatric evaluation and rehabilitation should be applied to all amputees, especially in cases of young, traumatic, transfemoral amputations. LEVEL OF EVIDENCE: Level 3, retrospective comparative cohort study.

Using fibula as a reference can be beneficial for the tibial component alignment after total knee arthroplasty, a retrospective study.

PURPOSE: One of the important factors in a successful arthroplasty is component alignment. The primary objective of this study was to determine whether the fibular shaft reference technique is beneficial for the tibial component position on the postoperative plain radiograph after total knee arthroplasty. METHODS: A total of 42 patients between 2009 and 2011 were analysed retrospectively. The surgeon prepared the tibia using an extramedullary cutting guide and set the posterior tibial slope with respect to the fibular reference rod. In the postoperative radiographic measurements, a true anteroposterior and lateral radiograph of the lower leg covering the whole length of the tibia was used. RESULTS: Five patients were excluded as they did not meet the inclusion criteria, four patients were excluded due to improper radiographs and the study group was reduced to 33 patients and 35 knees. The mean preoperative tibiofibular angle was 2.1° ± 0.8°. The mean postoperative tibial sagittal angle measurements were 83.3° ± 1.4° (81°-86°). 33 (94 %) Knees gained the desired tibial sagittal angle within the desired alignment (5° ± 3°). The mean postoperative tibial coronal angle was 89.3° ± 1.5°. The tibial component coronal angle of two knees was more than 3 alignment from the neutral mechanical axis. CONCLUSION: The major clinical relevance of the technique described in the present study is cost-effectiveness, and it does not require any extra time or surgical equipment. This method can be used as an alternative choice for bulky extremities which is a cause of malalignment of the components. LEVEL OF EVIDENCE: Retrospective case series, Level IV.

Farmedial versus anteromedial portal drilling of the femoral tunnel in ACL reconstruction: a computed tomography analysis.

INTRODUCTION: The success of ACL reconstruction is predicated on a variety of factors. Tunnel placement plays one of the most significant roles in achieving knee kinematics and function. The purposes of this study were to compare femoral tunnel position, angle, length and posterior wall blow-out after ACL reconstruction with hamstring tendons autograft through either a farmedial portal or an anteromedial portal technique. MATERIALS AND METHODS: We evaluated 36 patients who underwent ACL reconstruction between January 2014 and July 2014 in our institute, in a prospective, randomised cohort study. All the surgical procedures were performed by a sports fellowship-trained orthopaedic surgeon with experience in both portal reaming. The operated knees were evaluated with 0.5 mm fine CT scans of 3-D CT between days 3 and 5 postoperatively. RESULTS: According to the 3-D CT measurements, the mean femoral tunnel length was significantly longer (p < 0.05) in the FAM group compared with the AM group. The femoral bone tunnel length averaged 34.2 ± 3.6 mm versus 36.6 ± 3.0 mm (p = 0.042) in AM and the FAM groups, respectively. The femoral tunnel position, as evaluated with use of the quadrant method, was more anterior in the FAM transportal technique group, and the difference between the two groups was significant (p < 0.05). CONCLUSION: FAM tranportal drilling of the femoral tunnel creates longer and anterior femoral tunnels with regard to the AM portal drilling techniques. Additional studies with clinical outcomes are required for the clinical relevance of these techniques and to show which one is superior. LEVEL OF EVIDENCE: Level I, prospective randomised comparative cohort study.

Ilizarov fixator combined with an intramedullary nail for tibial nonunions with bone loss: is it effective?

BACKGROUND: Treatment of tibial nonunion with bone loss is extremely difficult. A variety of techniques have been described, but each has shortcomings, in particular prolonged external fixation time as well as serious complications such as nonunion and infection. Accordingly, we developed a technique that seeks to reduce these complications by using a circular external fixator in addition to an intramedullary nail to achieve union, limb lengthening, and stability of the regenerated segment. DESCRIPTION OF TECHNIQUE: First, the pseudoarthrosis area is resected, and acute compression is continued until bone contact at the docking site was achieved. Then primary grafting is applied to the docking site using a graft harvested from the patient's iliac bone, and the predrilled nail holes localized on the middle segment of the tibia are locked with a free-hand technique. Finally, lengthening is performed to overcome the leg-length discrepancy with an external fixator. METHODS: Between 2008 and 2011, this technique was used to treat five patients with tibial nonunion with bone loss. All patients were available for a minimum of a 14-month followup (mean, 30 months; range, 14-58 months). General indications for the procedure were age older than 16 years, tibial nonunion with bone loss, and the absence of any psychiatric disorder. We evaluated external fixation time, external fixation index (defined as the duration of external fixation in months divided by the total amount of bone transported and/or the amount of lengthening in centimeters), and time to union on plain radiographs, clinical results using the Paley bone and functional assessment scores, and postoperative complications from chart review. RESULTS: The external fixation time was 4 months (range, 3-5 months), and the average external fixation index was 0.4 months/cm. The mean time to bone union was 4.6 months (range, 3.5-5.5 months). All angles were determined to be in the normal range. No patients developed refracture or malalignment either on the docking site or the osteotomy site. Paley bone evaluation results were excellent in all five patients, and Paley functional results were excellent in four and good in one. We observed 10 pin-site infections as minor complications, and one patient was left with a residual equinus deformity of 5° as a major complication according to the Paley classification. CONCLUSIONS: Our technique combining acute shortening and distraction osteogenesis had promising results for the treatment of tibial nonunion with bone loss in a small group of patients. However, future studies directly comparing available approaches to this difficult problem are required. Because this problem is uncommon, these studies will almost certainly require the cooperation of multiple large participating centers. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Carpal tunnel release in patients with diabetes result in poorer outcome in long-term study.

BACKGROUND: The aim of this prospective study was to compare the results of surgical decompression of carpal tunnel syndrome (CTS) in patients with diabetes mellitus with those with idiopathic CTS. METHODS: The results of surgical decompression of CTS in 27 patients with diabetes mellitus were compared with 42 patients with idiopathic CTS. All patients underwent surgical release of transverse carpal ligament by the mini-incision of palm technique. Patient self-administered Boston Questionnaire (BQ) for the assessment of severity of CTS symptoms and hand functional status was evaluated before and 6 months and 10 years after surgery. RESULTS: After surgical release, all the patients of both groups reported an absence of pain, disappearance or reduction of paresthesia, and improvement in hand function. Six months after surgery, there was a significant improvement of symptomatic and functional BQ scores compared with preoperative state in both groups. Ten years after surgery, there was statistical difference in preoperative and postoperative 10th year functional BQ score between DM (-) and DM (+) (p < 0.01). DM status affected statistically functional BQ score between preoperative and postoperative 10th year. CONCLUSION: Diabetes mellitus was a risk factor for poor outcome of surgical decompression of CTS. Patients with diabetes had worse surgical outcome compared with patients with idiopathic CTS in long-term follow-up.

A comparison of the functional and radiological results of Paris plaster cast and ulnar gutter splint in the conservative treatment of fractures of the fifth metacarpal.

AIM: In the treatment protocol of fractures of the fifth metacarpal, closed reduction and immobilization is generally recommended. This study aimed to compare the radiological and functional results of short-arm plaster cast and a forearm U-splint. PATIENTS AND METHODS: Between January 2011 and June 2012, the study comprised a total of 122 cases with 64 (52.4%) in the cast group and 58 (47.6%) in the splint group. The cases were 92 (75.4%) males and 30 (24.6%) females with a mean age of 30.56 ± 12.27 years (range 10-66 years). Two groups were formed according to the surgical treatment plans of the two surgeons who were to follow up the patients. RESULTS: No statistically significant difference was found between the groups in terms of age, duration of the cast or splint and follow-up period (p > 0.05). The grip strength of Group A was determined as 90.38 ± 1.77% of the healthy side and Group B as 90.58 ± 1.65%. No statistically significant difference was seen between the groups in respect of grip strength (p > 0.05). The degree of dorsal angulation pre-application, post-application and after removal of the groups showed no statistically significant difference between the groups (p > 0.05). CONCLUSION: No superiority was seen in the clinical and radiological results of the two different treatment protocols applied to fractures of the fifth metacarpal. However, when the complications created by a plaster cast and pressure wounds are taken into consideration, the application of a short-arm U-splint can be said to be a better option.

Is step-cut shortening osteotomy a better choice than transverse osteotomy for total hip arthroplasty for Crowe type III-IV hip dysplasia?

INTRODUCTION: Total hip arthroplasty for developmental hip dysplasia is a challenging surgery due to anatomic abnormalities. Crowe III and Crowe IV hip dysplasia generally necessitates a subtrochanteric shortening osteotomy. Transverse and step-cut osteotomy are the most common procedures for shortening of femur although there is still no consensus which one is a superior method. The objective of this study was to demonstrate whether transverse or step-cut osteotomy is superior in hips who undergo arthroplasty for high riding hip dysplasia. HYPOTHESIS: Our hypothesis was that higher rates of union would be achieved in patients with Crowe III-IV hip dysplasia when the step-cut osteotomy was performed compared to transverse osteotomies. MATERIAL AND METHODS: A total of 99 hips from 90 patients (9 bilateral, 81 unilateral; 79 female, 11 male), each with a minimum follow-up duration of two years, were included in this study. The hips were classified as Crowe III (n=16) or IV (n=83). All hips were implanted cementless. Transverse or step-cut osteotomy was chosen for osteotomy type. The clinical and functional outcomes were assessed using the Harris Hip Score (HHS), limb length discrepancy (LLD), and limping. The complications and management of these were noted. The union rates were compared between osteotomy types. RESULTS: The mean age at surgery was 48.8 (range, 21-79 years). The follow-up period was 64.3 months in average (range, 24 to 192 months). The mean Harris Hip Score before surgery was 35.6 (range, 18-50), and increased to 88.1 (range, 61-98) points at the most recent follow-up. The preoperative leg length discrepancy (LLD) measured 5.3cm (with a range of 3 to 6.8), while the postoperative LLD reduced to 0.8cm (with a range of 0 to 1.6). There were a total of 38 complications in 35 patients out of 99 cases, resulting in a complication rate of 38.4%. The most frequent complication observed was intraoperative femoral fractures, occurring in 13 cases. Residual limping was seen in 73.7% of all. Step-cut osteotomy was performed in 64 hips (35 CDH stem [Zimmer Biomet, Warsaw, IN, USA], 29 Wagner Cone stem [Zimmer Biomet, Warsaw, IN, USA]) and, transverse in 35 hips (22 CDH, 13 Wagner Cone). Six hips had nonunion problem and all of them were operated with a step-cut osteotomy (z-score: -7.12 and p<0.00001, Mann-Whitney U Test). CONCLUSION: Transverse osteotomy may be a better option while performing a shortening subtrochanteric level osteotomy for total hip arthroplasty for Crowe III-IV hips. LEVEL OF EVIDENCE: Level III; observational retrospective cohort study.

Factors affecting mortality after hip fracture surgery: a retrospective analysis of 578 patients.

PURPOSE: To determine the effect of patient and surgical factors on mortality after hip fracture surgery. DESIGN: Retrospective study. SETTING: Level-one trauma and tertiary referral centers. METHODS: Patients were eligible if they were aged 65 years or older and had undergone surgery for a non-pathological femoral neck or intertrochanteric hip fracture between 2008 and 2011. The primary outcome was mortality: within the first year after surgery, after the first year, and survival as of the last questioning date. Of the 578 eligible patients, 399 (69%) were women; mean age was 79 years; and mean follow-up was 17 months. RESULTS: Mortality during the first year was significantly more frequent in patients aged 80 years or older (67 vs. 33%; P < 0.001). Estimated overall survival was significantly longer in women (43 vs. 37%; P = 0.01). The type of fracture had no impact on mortality (P = 0.96). Patients with high ASA class had a significant effect on mortality (P < 0.001). Surgery timing did not affect mortality in univariate analysis (P = 0.25). The mortality rate for hemiarthroplasty was higher than osteosynthesis options (P = 0.03). The effect of the type of anesthesia on mortality was not significant (P = 0.74). CONCLUSIONS: Older men had the highest risk of mortality within the first year. Patients with ASA ratings of class 3 or 4 need to be evaluated carefully because they appear to be at higher risk of early mortality. Osteosynthesis has a lower mortality than does arthroplasty for hip fracture and thus should be preferred if either treatment is possible. LEVEL OF EVIDENCE: IV.

How Kirschner Wires Crossing Each Other at the Fracture Site Affect Radiological and Clinical Results in Children With Gartland Type 3 Supracondylar Humerus Fractures?

Background In this study, we compared two groups of children with Gartland Type 3 supracondylar humerus fractures with respect to the crossing point of Kirschner wires (K-wires) in terms of radiological and clinical results after closed reduction and fixation with the crossed-pin technique. We hypothesized that even if medial and lateral pins cross each other at the fracture line, satisfactory radiological and clinical results would be achieved with the crossed-pin technique. Methodology A total of 59 patients with Gartland extension Type 3 supracondylar humerus fractures who underwent closed reduction and percutaneous crossed-pin fixation were included in the study. K-wires were crossing each other proximal to the fracture site in the proximal crossing group and at the fracture level in the fracture site crossing group. Loss of reduction, Baumann angle, shaft condyle angle, range of motion, and carrying angle were compared between the two groups. Results There were 43 males and 16 females in this study, with a mean age of 5.3±2.4 years. The average follow-up duration was 21.9 ± 5.2 weeks. In terms of loss of reduction in the coronal and sagittal planes, there was no statistical difference between the two groups. When the Baumann angle and shaft condylar angle of both groups were analyzed, no statistically significant differences were found at both early postoperative examination and final follow-up. Conclusions Although the crossing point of K-wires has been shown to be an important factor in the protection of reduction in biomechanical studies, it was not a significant factor for loss of reduction in this study. Factors except for the crossing point of K-wires may play a more important role in the outcomes of crossed-pin fixation.

Is proximal femoral nailing of unstable intertrochanteric fractures in the lateral decubitus position without a traction table as safe and effective as on a traction table?

OBJECTIVES: Using proximal femoral nailing (PFN) in the lateral decubitus (lateral) position may be an option when no traction table is available. We hypothesized that applying PFN would be effective and reliable in the lateral position without a traction table. To test our hypothesis, we compared the two techniques in a prospective, randomized controlled study. PATIENTS AND METHODS: Eighty patients (> 60 years of age) with unstable intertrochanteric fractures were randomly operated on prospectively in the lateral position without a traction table (Group 1) or in the supine position with a traction table (Group 2) between April 2018 and April 2019. We compared the surgery preparation time, total anesthesia time, duration of surgery, fluoroscopy exposure time, and amount of bleeding between the two procedures. The type-apex distance (TAD), collodiaphyseal angle (CDA), reduction quality, and lag quadrant were measured radiologically. The Harris Hip Score (HHS) was also calculated. RESULTS: The mean follow-up time was 18.5 (14-27) months in Group 1 and 19.9 (14-27) months in Group 2. The mean follow-up time, mean age, sex distribution, and fracture pattern were similar between the groups. The preparation time and total anesthesia time of Group 2 were longer than those of Group 1, and the fluoroscopy time of Group 2 was shorter than that of Group 1 (p < 0.05). No significant differences in surgical time, bleeding amount, TAD, CDA, target lag quadrant, reduction quality, or the HHS were observed between the two groups. CONCLUSIONS: We concluded that PFN is a safe and effective alternative for the treatment of unstable intertrochanteric femoral fractures when a traction table is not available in the operating room.

Foot Loading Analysis of Intra-articular Tibia Pilon Fracture.

BACKGROUND: Although pilon fractures are rare, they are important for orthopedic surgeons because of the difficulty of their treatment and their adverse effects on gait function. The aim of this was study to evaluate the relationship between the reduction quality of the fracture, functional results, ankle arthrosis, and plantar pressure distribution in patients with tibia pilon fractures. METHODS: In this study, a total of 62 patients treated for an intraarticular pilon fracture in our clinic between January of 2015 and January of 2019 were evaluated retrospectively. Postoperative reduction qualities of the patients were evaluated with the Ovadia-Beals criteria; ankle functional scores were evaluated with the Teeny-Wiss score; and ankle arthrosis was evaluated with the Takakura classification. At the last patient follow-up, foot loading analysis was performed, and the results were evaluated for their relation with postoperative reduction quality, ankle function, and ankle arthrosis. RESULTS: There were 62 patients (50 men and 12 women). The average age was 43.3 years (range, 19-78 years). The mean follow-up was 34.3 months (range, 24-58 months). The mean Ovadia-Beals score was 12.35 ± 4.6 on the postoperative plain radiographs of the patients; the mean Teeny-Wiss score at the last follow-up was 76.82 ± 17.69; and the mean Takakura score was 1.47 ± 1.35. Based on the pedobarographic measurements, 47.58% of the patients put weight on the anterior portion and 52.42% on the posterior portion of the foot in the anteroposterior plane. In the mediolateral plane, 42.15% loaded on the medial portion of the ankle and 57.85% loaded on the lateral portion of the foot. CONCLUSIONS: Intra-articular tibia pilon fractures can be demonstrated by lateralization of the walking axis and changes in gait patterns and can be associated with clinical outcome.

Seasonal variation in paediatric orthopaedic trauma Patients - A single centre experience from Turkey.

PURPOSE: It is known that the incidence of paediatric orthopaedic trauma peaks in the summer months as a result of increased and uncontrolled physical activity. The aim of this study was to review the experience of a single centre with paediatric orthopaedic traumas and determine the relationship between the severity and the variations in the incidence of traumas in relation to the seasons and temperatures during the study period. MATERIALS AND METHODS: A single institutional review of the historical data of all patients aged 0-16 years who presented for orthopaedic trauma between January 2018 and December 2020 in the emergency department of Level 1 tertiary orthopaedic trauma centre was conducted. 65,182 paediatric orthopaedic trauma cases had been retrieved from the hospital data base during the 3 -year study period. We classified the traumas according to the variants of the patients' and by holidays, seasons, school days and weekends, months and in which part of the body it occurred. RESULTS: After excluding the summer vacation, 77% of paediatric orthopaedic trauma patients attended to the hospital on weekdays and 23% on weekends. While it was observed that hot weather had a statistically positive effect on trauma attendance, rainy weather had an negative effect (p < 0.05). Trauma attendances were found to be statistically higher in summer months, except for injuries that may occur with indoor activities such as metacarpal fracture, phalanx fracture and pulled elbow (p < 0.05). CONCLUSION: Orthopaedic trauma at a Level 1 tertiary health care trauma center do vary significantly with the weather and are highest in the summer season. Therefore, it should focus more attention on preventive strategies for paediatric trauma in the summer season.
