Periosteal chondrosarcoma, also known as juxtacortical chondrosarcoma, is a rare malignant cartilaginous tumor that can appear on the external surface of bone. This tumor represent less than 2% of all chondrosarcomas and 0.2% of all bone tumors. Periosteal chondrosarcoma has been reported more frequently in males and in the fourth decade of life.Their clinical presentation is non-specific but there may be pain, swelling and loss of function and usually affects the metaphyses of the long bones, especially the femur and humerus. The diagnostic is established imagistically (Rx, CT, MRI) which describe aspects characteristic of the tumor and of course based on histopathological examination with a specific description: a solid lobulated tumor, with focally myxoid stroma and chondroid cells with a variable degree of atypia. The treatment of choice is wide surgical resection. The prognosis for these patients is relatively good, with 80-90% long term survival and a low rate of metastases. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Virtually all early cases of knee osteoarthritis have degenerative medial meniscus lesions accompanying the chondral defects on MRI. It is difficult to determine if the symptoms are caused by the unstable meniscus or by osteoarthritis, hence unclear guidance towards treatment. We, therefore, aimed to determine the clinical improvement following arthroscopic meniscectomy compared to intraarticular administration of corticosteroids for degenerative ruptures of the medial meniscus in the presence of early stage medial compartment knee osteoarthritis. PATIENTS AND METHODS: We included 120 consecutive cases of nontraumatic symptomatic knees which had degenerative lesions of the medial compartment (cartilage and meniscus) on MRI's. They were randomized to receive either intraarticular steroid injection or arthroscopic debridement. We also analyzed the correlation between BMI, age, gender, MRI, intraoperative aspect of the meniscus and cartilage and clinical improvement using the Oxford Knee Score up to one year. At one month there was significant improvement of the scores for all the examined cases. Also at one month, the arthroscopic group performed better in terms of symptom improvement. This was maintained for 79% of the knees in the arthroscopic group and 61% in the intraarticular steroid injection respectively, out of those available for follow up at one year. RESULTS: At one month, symptoms reappeared for 12 patients in the steroid group and 7 in the arthroscopy respectively. Gender and age did not correlate with treatment, whereas extrusion of the meniscus, bone marrow edema, duration of the clinical symptoms, obesity and a low preoperative score were negative prognostic factors. CONCLUSIONS: Degenerative medial meniscal tears, in the presence of osteoarthritis, can only marginally benefit from arthroscopic debridement over intraarticular steroid injections in short term follow up. When considering individual cases, factors become more predictive when analyzed in group. [ABSTRACT FROM AUTHOR]

The incidence of ACL tear and reconstruction has increased over time, and failure of ACL reconstruction is not perfectly defined among surgeons. Atraumatic failure of ACL surgery represents approximately 70% of causes, and occurs in diagnostic errors, technical errors and problems of ACL graft integrations. Regarding surgical technique, we should answer certain questions about our choice of surgery, tunnel position, graft type, graft suture, tensioning the graft, and how we deal with certain incidents or intraoperative accidents. The purpose of this article is to review the current information and trends of ACL reconstruction, and presents some tips and tricks we use in our current practice.

SUMMARY STATEMENT THE PERCENTAGE OF HIP REVISION IS AROUND 6% AT FIVE YEARS AND 12% AT TEN YEARS AFTER A PRIMARY ARTHROPLASTY. THIS PROSPECTIVE STUDY REVEALS A THERAPEUTIC OPTION FOR PERIPROSTHETIC FRACTURES, PROXIMAL FEMUR TUMORS AND ASEPTIC OR SEPTIC OSTEOLYSIS. MATERIAL AND METHOD FOURTEEN PATIENTS WERE TREATED WITH THE KENT HIP (BIOMET EUROPE, DORDRECHT, THE NETHERLANDS) BETWEEN 2006 AND 2012 FOR A NUMBER OF INDICATIONS SUCH AS PERIPROSTHETIC HIP FRACTURES (7 PATIENTS), PROXIMAL FEMUR TUMORS (3 PATIENTS), CUT OUT FOLLOWING INTERNAL FIXATION (ONE PATIENT), SEPTIC LOOSENING (ONE PATIENT), AND ASEPTIC LOOSENING (ONE PATIENT) AND SEVER RENAL OSTEODYSTROPHY (OSTEOPOROSIS T SCORE OF-4,9 AT THE HIP, ONE PATIENT). RESULTS AVERAGE FOLLOW-UP WAS 12 MONTHS, EXCEPT FOR ONE PATIENT WHO DIED. THE AVERAGE TIME TO FULL WEIGHT BEARING WAS 3 DAYS AND THE AVERAGE FUNCTIONAL HIP HARRIS SCORE WAS 72% AT 1 YEAR POSTOPERATIVE. SUBJECTIVE EVA LUATION WAS FAIR WITH 21% OF THE PATIENTS THAT WERE DISAPPOINTED REGARDING THE FUNCTIONAL TESTS AT ONE YEAR AFTER SURGERY. CONCLUSION THESE FUNCTIONAL RESULTS EVEN WHEN COMPARED WITH OTHER SIMILAR, NEWER, MORE COMPLEX AND MORE EXPENSIVE IMPLANTS ARE VERY GOOD. DESPITE THE SMALL NUMBER OF PATIENTS WE CONSIDER THAT THE KENT HIP SYSTEM CAN BE USED WITH GOOD RESULTS IN SELECTED CASES DUE TO ITS TECHNICAL ADVANTAGES SUCH AS EXCELLENT DISTAL LOCKING IN THE FEMORAL CANAL AND VERSION, OFFSET AND LIMB LENGTH CORRECTION.

Background and Objectives: This longitudinal study investigated the correlation between imaging findings and self-reported questionnaire outcomes in patients with tibiofibular diastasis, exploring the effects of surgical screw removal versus conservative treatment. This study was conducted at "Victor Babes" University of Medicine and Pharmacy in Timisoara between 2018 and 2023., Materials and Methods: The study involved 85 patients in the screw removal group and 44 in the conservative group, assessed at 2 and 6 months post-surgery, answering the SF-36, HADS, and WHOQOL questionnaires., Results: Significant differences were observed at 2 months post-surgery, with the screw removal group showing lower shear wave velocities in ankle dorsiflexion (8.9 ± 1.4) and anterior talofibular ligament (2.8 ± 0.9), indicating better mobility compared to the conservative group (ankle dorsiflexion: 10.1 ± 1.8, ATFL: 3.2 ± 1.1). Radiographically, lower tibiofibular overlap (8.1 ± 2.1) in the screw removal group suggested improved joint fixation quality. These physical improvements were mirrored in the quality-of-life assessments, where the screw removal group reported higher physical health scores on the SF-36 survey at 2 months, a trend that continued at 6 months. At 2 months, ankle dorsiflexion demonstrated a strong negative correlation with the SF-36 Physical score (r = -0.417) and WHOQOL Physical domain (r = -0.394), and a positive correlation with HADS Anxiety (r = 0.312). Similarly, ATFL and CFL velocities negatively correlated with the SF-36 Physical score (ATFL: r = -0.251; CFL: r = -0.237). Radiographic tibiofibular overlap and clear space positively correlated with WHOQOL Physical domain (TOL: r = 0.291; TCS: r = 0.276), with TCS also negatively correlating with HADS Anxiety (r = -0.228). At 6 months, these correlations persisted, with notable negative correlations between ultrasound ankle dorsiflexion and both SF-36 Physical score and WHOQOL Physical domain., Conclusions: These findings underscore the advantages of screw removal in enhancing physical recovery and reducing anxiety in the short term, while indicating similar long-term mental health outcomes between treatment approaches.

Background and Objectives: While numerous studies have been conducted on syndesmotic screw management following distal tibiofibular diastasis repair, a clear consensus remains unclear. This research aims to evaluate whether the postoperative removal of syndesmotic screws leads to improved patient outcomes, specifically in quality of life, mobility, and daily living activities, and whether it offers a cost-effective solution. Materials and Methods: Patients with a history of unimalleolar or bimalleolar ankle fractures, classified according to the Danis-Weber and Lauge-Hansen systems, were included. Comprehensive evaluations were made via standardized questionnaires like the SF-36 Health Survey, HADS, and WHOQOL-BREF, distributed approximately 2 months post surgery. A total of 93 patients underwent syndesmotic screw removal while 51 retained the screws (conservative approach). Results: Patients who underwent screw removal reported superior satisfaction in mobility, with a score of 7.8, compared to 6.7 in the conservative approach ( p = 0.018). Similarly, their ability to perform daily activities scored 8.1, higher than the 6.5 from the conservative cohort ( p < 0.001). Pain levels were also more favorable in the screw removal group, with a score of 5.3 against 6.8 in the conservative group ( p = 0.003). On the SF-36 physical domain, the screw removal group achieved a mean score of 55.9 versus 53.3 for the conservative group ( p = 0.027). Notably, the HADS anxiety subscale highlighted reduced anxiety levels in the screw removal cohort with a mean score of 5.8 against 7.3 in the conservative group ( p = 0.006). However, overall quality of life and recommendations to others showed no significant difference between the groups. Conclusions: Syndesmotic screw removal postoperatively leads to marked improvements in patients' mobility, daily activity abilities, and reduced postoperative pain and anxiety levels. However, overall quality of life was similar between the two approaches. The findings offer valuable insights for orthopedic decision making and patient-centered care concerning the management of syndesmotic screws after distal tibiofibular diastasis repair.

Purpose: The modified anterolateral approach (Röttinger) for total hip arthroplasty (THA) offers great advantages over conventional approaches, especially concerning early postoperative symptoms, which are mild and well tolerated by patients. Robotic-assisted implantation might facilitate rapid adoption of the modified anterolateral approach without exposing surgeons to risks encountered during the learning curve. This study posits that the use of robotic assistance in conjunction with the modified anterolateral approach for total hip arthroplasty (THA) can provide a substantial enhancement in the accuracy of cup placement in comparison to manual surgery., Methods: Thirty-two robotic-assisted THAs met the inclusion criteria and were matched to 32 conventional cases. Acetabular cup inclination, anteversion, limb-length discrepancy, and acetabular offset were assessed using certified planning software by two independent observers using pre- and postoperative anterior-posterior radiographs. Data was analyzed for normal distribution. Chi 2 test was used to determine whether implanted acetabular cups that were within Lewinnek's safe zones were influenced by type of implantation. Effect size estimates and statistical power analysis were also performed to appreciate the appropriateness of the chosen sample size., Results: Robotic-assisted implantation was found to significantly improve acetabular cup placement in terms of inclination (p < 0.001) but not anteversion (p = 0.783). Although mean postoperative limb-length discrepancy and mean acetabular offset did not differ between groups, a significantly smaller variance was found in the robotic-assisted group (p < 0.001) and (p = 0.04), respectively. There were no significant differences between the two groups in terms of consistently implanting the acetabular cup within the Lewinnek safe zones p = 0.641 for anteversion and p = 0.230 for inclination, respectively., Conclusions: Our results show that although robotic-assisted acetabular cup implantation performed through the modified anterolateral approach did not significantly differ from conventional implantation, it did offer increased accuracy in cup positioning, acetabular bone preservation, and limb-length restoration., (© 2023.

Purpose: Patient-specific instruments (PSI) have been designed to improve the accuracy of performing opening-wedge high-tibial osteotomies (OW-HTO). This study aims to evaluate the lower limb alignment, by comparing pre-operative desired correction to post-operative achieved correction, the difference in surgical time and number of radiological exposures in OW-HTO using patient-specific instruments (PSI) versus conventional osteotomies and the specific and non-specific complications that occurred., Methods: We performed a single-centre, retrospective, observational study, including 25 consecutive patients undergoing OW-HTO using PSI, from January 2019 to October 2020., Results: Pre-operatively, the mean hip-knee angle (HKA) was 167°, the mean tibial slope was 7.9° and the mean medial proximal tibial angle (MPTA) was 82.5°. Post-operatively, the mean HKA was 182.2° (180.1-184.7°), the tibial slope was 6.5° (4.2-12.9°) and the MPTA was 92.8° (90.6-93°). In both coronal and sagittal plane, all knees were within 2° from the planned value. The mean tourniquet time, by which the surgical time was measured, was 40 minutes and the average number of intra-operative fluoroscopic images was 10 (range: 7-14), significantly less than when using conventional techniques., Conclusions: The use of PSI in OW-HTO allows accurate achievement of the desired correction, while shortening the OR time. The number of radiological exposures is also decreased, in comparison with the conventional osteotomies.

Purpose: The neutrophil to lymphocyte ratio (NLR) is a simple predictor used in oncology and cardiology. We aimed to analyze the NLR profile of patients with diaphyseal fractures of the humerus, femur, and tibia., Methods: We performed a cross-sectional, consecutive-case population-based study including 148 patients (41.9% men respectively 58.1% women) with humeral (23.0%), femoral (30.4%), and tibial (46.6%) diaphyseal fractures, admitted for surgical treatment in our level 1 trauma centre over two years., Results: The differences in NLR between the studied subgroups were not significant (p = 0.067), the highest value being observed in patients with femoral fracture (5.6) in contrast to patients with humeral fracture (4). In the global cohort, there was a significantly positive correlation between NLR and PLR (platelet to lymphocyte ratio; Spearman's r = 0.595; p < 0.001). The stratified subgroup analysis found significant association between NLR and duration of admission only for patients with femoral fracture (Spearman's r = - 0.308; p < 0.001). When compared with controls, all three fracture types had significantly higher neutrophil numbers and NLR and lower thrombocyte numbers., Conclusions: NLR are elevated in femur diaphyseal fractures compared with tibia and humerus, up to cut-off values with negative prediction of outcome in malignancy and cardiovascular patients. Increased NLR are predictive of longer hospital admissions for femur fractures.

Objective: Perform translation, cultural adaptation and psychometric testing of the Romanian translation of the Hip disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS&#95;JR)., Design: Assess construct validity, reliability, internal consistency and reproducibility., Setting: Adults with chronic hip disability prior or at a minimum of 3 months after surgery., Participants: Ninety-six patients (22 bilateral) with hip osteoarthritis or who had previous hip replacement or osteosynthesis for a fracture of the trochanteric region., Intervention: Complete the HOOS&#95;JR together with the Oxford Hip Score (OHS&#95;RO), Harris Hip Score (HHS) and Euroqol EQ-5D. 57 patients repeated the HOOS&#95;JR after 2 days., Main Outcome Measure: Convergent validity using Spearmans's correlation coefficient; Cronbach's alpha coefficient, intraclass correlation coefficient (ICC, two-way mixed effects model) and inter-item correlation matrix and test-retest assessment after 2 days., Results: The questionnaire had a high degree of reliability with a Cronbach's α of 0.923 at the initial completion and 0.924 at the second testing. The ICC was 0.923 for average measures for the first form and 0.910 for the second form. The two results were strongly, positively and significantly correlated (rs = 0.859; P < 0.001). The Romanian HOOS&#95;JR strongly, significantly and positively correlated with the OHS&#95;RO (rs = -0.880 initial and rs = -0.803 s; P < 0.001) and HHS (rs = -0.731 initial and rs = -0.654 s; P < 0.001) and moderately, significantly and positively correlated with the EQ-5D Index (rs = -0.580 initial and rs = -0.542 s; P < 0.001) and VAS (rs = -0.500 initial and rs = -0.690 s; P < 0.001)., Conclusions: The translated HOOS&#95;JR is a reliable, reproducible and valid measure of function in patients with chronic hip disability., (© The Author(s) 2018.

Background: Deep vein thrombosis is a well-known complication of fracture occurrence, lower limb surgery and periods of prolonged immobilisation. Its incidence can be increased even more in specific cases with metastatic bone disease and adjuvant treatment. There is a small amount of literature that addresses the incidence of DVT by comparing osteosynthesis and arthroplasty as surgical treatments. Current recommended anticoagulation protocols might be inadequate for specific groups of cancer patients undergoing osteosynthesis or arthroplasty., Methods: The study was designed and performed in a retrospective manner and carried out on patients that presented at our Emergency Clinical County Hospital between 01.01.2008-31.12.2016. The patients' evolution was followed for a standard of 2 months. All our deep vein thrombosis events were diagnosed via venous duplex imaging. The studied lot (n = 85) was paired with a control group (n = 170) with similar baseline characteristics., Results: Our lot was comprised of 85 patients that underwent 85 surgeries, on both of our hospital's Orthopaedic and Traumatology wards. When performing the student t-test and calculating OR (odds ratio) and RR (risk ratio) we encountered 11 cases of DVT in our studied group and 12 cases of DVT in our control group (p < 0.04). We found statistical significance when correlating DVT with type of implant (prosthesis), the presence of metastases over primary tumour and the choice of implant (prosthesis over intramedullary nail). There was no statistical significance found when correlating DVT events with the type of anticoagulation and the amount of blood transfusion units required., Conclusion: Patients who undergo surgical treatment for lower limb pathological fracture due to malignancy are at increased risk of DVT or death due to PE under current general thromboprophylaxis regimens. The risk is higher for the immediate postoperative period (10 days). The risk is increased by metastasis, arthroplasty and adjuvant therapy (radiotherapy, chemotherapy), and we think that a more aggressive prophylactic protocol should be used.

Purpose: We aimed to perform psychometric testing for the translated Oxford Hip Score (OHS) for use as a recommended tool to measure treatment outcomes., Methods: The original English questionnaire was translated and culturally validated using the instrument developer's guidelines and the ISPOR principles of good practice. One hundred patients completed the form together with the Harris Hip Score (HHS) and EQ-5D-5 L. Fifty patients repeated the form after two days. They were suffering from hip osteoarthritis, had had hip replacement or underwent osteosynthesis for a fracture of the trochanteric region., Results: The questionnaire had a high degree of reliability with a Cronbach α of 0.917 at the initial completion and 0.917 at the second testing, respectively. The two results were strongly positive and significantly correlated (Pearson's r = 0.947; p < 0.001). The OHS was strongly and significantly correlated with the HHS (Pearson's r = 0.880 initial and r = 0.840 s; p < 0.001) and strongly, positive and significantly correlated with the EQ-5D-5 L VAS (Pearson's r = 0.614 initial and r = 0.704 s; p < 0.001)., Conclusions: Our study showed that the translation of the OHS is a reliable, reproducible and valid measure of function in patients who undergo treatment for hip pathology.

Distal tibia fractures are reported to have a high complication rate pre-operatively as well as post-operatively, which can include open fractures, soft tissue damage, infection, malalignment, pseudarthrosis and ankle arthrosis. The operative treatment for the extra-articular distal tibia fractures is a controversial topic in the orthopaedic literature. Some of these fractures are proximal enough to be treated with an intramedullary nail while others are too distal for that. The aim of our study was to compare the results we have had with intramedullary nail (IMN) and minimally invasive plate osteosynthesis (MIPO) in distal metaphyseal (extra-articular) tibia fractures. The study was designed prospectively between January 2013 and March 2016 and took place on the Orthopaedics and Traumatology ward of a Clinical Emergency County Hospital in western Romania. The follow-up visits were scheduled one month, three months and six months post-operatively. For evaluating the ankle function, we used the Olerud-Molander ankle score (OMAS) and union was evaluated at six months on ankle X-rays. At the six-month follow-up visit the average scores were 75.55 (20-100) for the IMN lot and 74.23 (20-90) for the MIPO lot, without finding any statistical difference between the two groups (p >0.1). At the six-month follow-up, X-ray union was objected in 48 (90.5%) of our patients, the IMN lot having worse results (85.18%) than the MIPO lot (96.15%). The results we encountered showed little to no statistical difference when it comes to the functional score we used (OMAS score), leading us to believe that you can achieve comparable results with both implants.

Background: The key to a successful knee replacement is restoring normal kinematics with a neutral alignment, thus a hip-knee-ankle (HKA) angle of 180° (within 3° limits). Conventional TKR is proven to have excellent results but relies in extensive visual referencing of bony landmarks. Customised cutting blocks provide accurate bone cuts, also lowering the risk of fat embolism, blood loss and operating time., Method: We share our experience comparing two different TKA techniques using patient specific instrumentation (PSI) with the Visionaire knee and conventional instrumentation (CVI) from the same system (Genesis II Smith&Nephew). A total number of 80 knees were divided into two equal groups, 40 PSI and 40 CVI respectively, operated between April 2013 and August 2014. One female patient had bilateral TKR during this period, at six months interval, both with the PSI., Results: All operated knees had varus deformity, with a mean HKA of 168° (PSI) vs 163° (CVI). We used tranexamic acid (double-dose scheme) and suction drains for 48 hours, with a mean blood drainage in the PSI group of 185 ml and Hb levels of 11.2 g/dl at three days post, compared to 260 ml and 10.7 g/dl in the CVI. Mean blood loss was 3.5 g/dl in PSI, and 4.2 g/dl in the CVI. On the long leg standing radiograph at six weeks, all knees were aligned in frontal plane, with simillar HKA values (178.9° PSI vs 178.6° CVI). Bone cuts measured intraoperatively proved to be accurate within a 1 mm limit., Conclusions: We cannot recommend PSI-TKR for a better outcome. It is an alternative to conventional and computer-assisted TKR, but further studies are needed to evaluate weather surgical or economic benefits may be achieved by choosing customised instruments.

Background: Occult hip fractures are often difficult to identify in busy trauma units. We aimed to present our institutions experience in the diagnosis and treatment of occult fractures around the hip and to help define a clinical and radiological management algorithm., Method: We conducted a seven-year retrospective hospital medical record analysis. The electronic database was searched for ICD-10 CM codes S72.0 and S72.1 used for proximal femoral fractures upon patient discharge. We identified 34 (4.83 %) femoral neck fractures and 48 (4.42 %) trochanteric fractures labeled as occult., Results: The majority of the cases were diagnosed by primary MRI scan (57.4 %) and 12 were diagnosed by emergency CT scan (14.6 %). For the remaining cases the final diagnosis was confirmed by 72 h CT scan in 9 patients (representing 39 % of the false negative cases) or by MRI in the rest of 14 patients. MRI was best at detecting incomplete pertrochanteric fracture patterns (13.45 % of total) and incomplete fractures of the greater trochanter (3.65 % of total) respectively. It also detected the majority of Garden I femoral neck fractures (20.7 % of total). CT scanning accurately detected 100 % of Garden 2 fractures (2.44 %) and 25 % (3.65 %) of the complete pertrochanteric fractures (false negative 25 %)., Conclusion: Occult fractures should be suspected in all patients with traumatic onset of hip pain that is inconsistent with normal radiographic findings. MRI is the golden standard but not as readily available not as cheap and not quite as quick to perform as as a CT scan. The latter which in turn can provide falsely negative results in the first 24 h. Improved imaging protocols could expedite management and improve treatment.

Purpose: The reporting of gait analysis data on operated fractures of the tibial plateau, while extensive for studies of knee osteoarthritis of mostly undisclosed aetiology and ACL deficient knees, is rather limited in literature., Methods: In the present study we investigated 25 tibial plateau fractures classified as Schatzker II, IV, V and VI that underwent operative reduction and lateral plate osteosynthesis. Apart from routine radiographic exploration and patient completed (KOOS) scores at three (mean of 3.2 months), six (mean of 5.6 months) and 12 months (mean of 11.3 months) postoperatively, gait analysis was performed at these intervals as well. Cadence, step time and knee flexion were the gait parameters that were selected for the comparison at six and 12 months postoperatively., Results: The analysed gait parameters were significantly improved between the six and the 12-month session and statistically significant differences were found between the two groups of values. Cadence had a mean value of 41 steps/minute at six months and 45 steps/minute at 12 months (p = 0.99). Step time was a mean of 0.74 seconds at six months while at 12 months the median value was 0.66 seconds (p = 0.94). Knee flexion angles evolved in a similar manner with mean values of 58° at six months and 69° at 12 months (p = 0.95). The mean KOOS scores were 42.4, 56.3 and 67.99 at three, six and 12 months postoperatively, respectively., Conclusion: Complex intra-articular fractures, classified as Schatzker IV, V and VI, had a higher impact on joint function than Schatzker II fractures treated with similar techniques and implants. There were statistically significant improvements in the recovery status at 12 months postoperatively compared to six months with extended chances for improvement.

Introduction: Modular femoral implants have become a regular feature of revision hip surgery. However, for a primary hip arthroplasty, such as a femoral neck fracture case, the implant of choice is a standard femoral component, while compelling literature evidence have made osteosynthesis the standard procedure for the vast majority of trochanteric fractures., Case Presentation: We present the case of a 66-year-old Caucasian woman presenting with two trochanteric fractures associated with primary and secondary hip osteoarthritis that were treated with an uncemented total hip replacement with a modular femoral component., Conclusions: We found that a modular femoral component can address the issues of stability and, in our case, proved to be a viable solution for treating cases that are complicated by concomitant acetabular or femoral head and neck pathology.

The purpose of this prospective observational study is to identify whether or not reaming of tibial shaft fractures has benefits over unreamed intramedullary locked nailing. Eighty-four adult patients with recent open and closed tibial shaft fractures were treated with reamed or unreamed intramedullary locked nail fixation. We followed up for 12 months 39 of 43 patients in the unreamed and 38 of 41 patients in the reamed group, respectively. There were no significant differences between the two groups regarding the average time to healing for both clinical (3.2 vs 3.4 months, p = 0.65) and radiological (4.1 vs 4.5 months, p = 0.43) evaluations. The mean duration of surgery was shorter (p = 0.025) for the unreamed group 43 min (SD 18) compared to 55 (SD 27), but the main determinants were the fracture type and the surgeon's experience. We conclude that reamed nailing proved beneficial, but the impact on overall outcome is not superior to unreamed nailing.
