Comparative Study
PURPOSE
The purpose of this study was to analyse the difference between arthroscopic fixation and open reduction internal fixation (ORIF) of posterior cruciate ligament (PCL) tibial avulsion fractures.
METHODS
This retrospective study analysed patients with an acute PCL tibial avulsion fracture who underwent surgical treatment at our hospital and follow-up for at least 24 months. Variables based on sex, age, Meyers-McKeever type, surgical method, meniscus tear, external fixation, labour or sports, Lysholm knee score, IKDC score, and KT-1000 value were also recorded. Multifactor unconditional logistic regression and Student's t test with 1:1 propensity score matching (PSM) to remove confounding factors were used for analysis.
RESULTS
Sixty-five cases achieved knee function graded as "good" or better, and 9 cases not. Single-factor analysis indicated that Meyers-McKeever type (χ = 4.669, P = 0.031) and surgical approach (χ = 9.428, P = 0.002) are related to functional outcomes. Multifactorial logistic regression analysis further confirmed that Meyers-McKeever typing (OR = 10.763, P = 0.036, [95% CI 1.174-98.693]) and surgical approach (OR = 9.274, P = 0.008, [95% CI 1.794-47.934]) are independent risk factors affecting prognosis. In addition, PSM verified significant differences in the Lysholm score (t = 3.195, P = 0.006), IKDC score (t = 4.703, P = 0.000) and A-KT/H-KT (t = 2.859, P = 0.012). However, the affected-side KT-1000 value (A-KT, mm, t = 1.225, P = 0.239) and healthy-side KT-1000 value (H-KT, mm, t = 1.436, P = 0.172) did not significantly differ between the two groups. The proportions of cases in which the Lysholm score, IKDC and A-KT/H-KT exceeded the minimal clinically important difference (MCID) were 62.5% (20/32), 62.5% (20/32) and 93.75% (30/32), respectively.
CONCLUSION
Compared with ORIF, an arthroscopic approach for PCL tibial avulsion fractures achieves better results.

A tibial spine fracture refers to an intraarticular fracture of the osseous insertion of the anterior cruciate ligament at the proximal tibia, commonly seen in pediatric and adolescent patients. This fracture is classified based on the degree of displacement and the presence or absence of an intact posterior hinge point. For significantly displaced fractures, surgical reduction and fixation are often recommended. Both open and arthroscopic approaches have been described. This technical note describes our technique for arthroscopic-assisted reduction and fixation of tibial spine fractures using trans-osseous tunnels and suture fixation over a bone bridge. This technique restores native anatomy, provides fracture compression, and has favorable biomechanical properties, allowing for early range of motion.

OBJECTIVE
In complicated Neer three- and four-part proximal humerus fracture (PHF), greater tuberosity (GT) fragments are often comminuted, and the currently widely used locking plate may not fix GT fragments effectively. A further understanding of morphological characteristics of the GT fragments may help explore new fixation devices. This study aimed to determine the fracture line morphology of the GT fragment of Neer three- or four-part PHF and analyze the location relationship between the locking plate and the GT fragment.
METHODS
Seventy-one three-dimensional computed tomography scans of Neer three- and four-part PHF were retrospectively reviewed between January 2014 and June 2019. Fracture fragments were reconstructed and virtually reduced in the Mimics software, and fracture lines of GT fragments were depicted on a humerus template in the 3-matic software and then were superimposed altogether. The common sites of the GT fracture were identified, and the location relationship between the locking plate and GT fragments was analyzed in a computer-simulated scenario.
RESULTS
The fracture line morphology of GT fragments was similar between Neer three- and four-part PHF. The overall morphology of GT fragments was in a fan shape, which could be summarized as anterior, superior, posterior, and middle lines. Of these, we identified 51 split and 29 avulsion type GT fragments based on the Mutch classification, and they could occur simultaneously in a PHF. The overall morphology of split type fragments was in a fan shape, and avulsion type fragments showed a quite distinguishable distribution pattern. A GT fragment could be classified as anterior-split, posterior-split, complete-split, anterior -avulsion, and posterior-avulsion type based on its morphology and location. The median percentage of fragment area covered by the plate was 32.3% in all of the fragments, and it was 69.4%, 23.0%, 37.2%, 21.8%, 0.0% in anterior-split, posterior-split, complete-split, anterior-avulsion, and posterior-avulsion type GT fragments. We defined the posterior-split, anterior-avulsion, and posterior-avulsion type GT fragments as the risky GT fragments, and they occurred in 43 (60.6%) Neer three- and four-part PHFs.
CONCLUSION
The fracture line morphology of GT fragments of Neer three- and four-part PHF was in a fan shape. GT fragments could be classified based on their location and morphology. The extent of GT fragment coverage provided by the locking plate differed in various fragment types, and we identified the anterior-avulsion, posterior-avulsion, and posterior-split type fragments as the risky GT fragments with a high incidence rate in Neer three- and four-part PHFs.

BACKGROUND AND PURPOSE
The Lubinus SP2 stem has been associated with a very low risk of periprosthetic femoral fractures (PPFFs). We aimed, primarily, to study the radiographic morphology of PPFFs close to a Lubinus SP2 stem. Secondarily, we analyzed whether higher reoperation rate was correlated to the revision method chosen or to the characteristics of the fracture and of the bone.
PATIENTS AND METHODS
The study included 156 femoral fractures close to a Lubinus cemented stem. These fractures were treated in 40 hospitals in Sweden between 2006 and 2011 and were followed up until 2019. Data from the Swedish Arthroplasty Register was used. Medical records and radiographs were studied. The fractures were classified according to the Vancouver classification. The fracture location and anatomy were delineated. We also measured the remaining attachment index (RAI) and the canal thickness ratio.
RESULTS
Vancouver type C (n = 101) and spiral fractures (n = 67, 41 in Vancouver C and 26 in Vancouver B) were the most common fracture types. 4 fractures were avulsion of the greater trochanter. The remaining 51 fractures occurred around the stem (B1: 25, B2: 16, and B3: 10). B fractures were more commonly reoperated on (18 of 51, 35%) than type C fractures (11 of 101, 11%, P = 0.001). In most femurs with type B3 fracture, the fracture line covered an area only around the stem, but in all B1 and in 11 of 16 B2 fractures, it was extended even distal to the stem. ORIF instead of stem revision in B2 fractures, use of short stems or plates, and inadequate reduction of the fractures were risk factors for subsequent reoperations.
CONCLUSION
The higher reoperation rate in type B fractures, compared with fractures distal to the stem, could be caused by their higher degree of complexity and reduced capacity for healing in the region around the stem.

The degree of fracture reduction does not compromise the clinical efficacy of arthroscopic reduction and fixation of tibial posterior cruciate ligament avulsion fractures: A retrospective study.
This study aimed to explore the postoperative outcomes of patients who underwent arthroscopic internal fixation with repositioning sutures for the treatment of posterior cruciate ligament (PCL) avulsion fractures with poorly reduced fracture fragments. It was hypothesized that improperly repositioned fracture fragments might not influence the postoperative clinical outcomes in patients with PCL avulsion fractures treated by arthroscopic sutures. From January 2020 to December 2021, patients admitted to our hospital with PCL avulsion fractures were evaluated. Our inclusion criteria were as follows: diagnosis of PCL avulsion fracture as Meyers & McKeever Type II or Type III; underwent arthroscopic double tunnel suture fixation; and age below 70. Of the patients meeting these criteria, data from 34 individuals were collected by a designated follow-up officer. Based on postoperative imaging, the patients were divided into 2 groups: well fracture reduction and poor fracture reduction groups. Prior to the surgery, the Lysholm score, knee mobility, and international knee documentation committee (IKDC score) were recorded for both groups. At the 3-month post-surgery mark, CT-3D reconstruction was performed. Statistical analysis was conducted on the collected data. For data that conformed to a normal distribution, the t test was applied. For data that didn't conform, we used a non-parametric test. Both groups achieved successful wound healing without encountering any adverse events, such as fracture nonunion infection. Fracture healing was observed in both groups at the 3-month postoperative mark. The average follow-up duration was 13.24 ± 6.18 months. There were no significant differences in Lysholm score, IKDC score, or knee mobility between the well- and poorly-reduced groups at the final follow-up (P > .05). Postoperatively, both groups demonstrated significant improvements in knee function compared to the preoperative scores, with statistically significant differences observed in Lysholm score, IKDC score, and knee mobility (P < .05). Arthroscopic fixation with double-tunnel sutures proved to be a highly effective treatment approach for PCL avulsion fractures, even in cases where the fractures were poorly reduced. Remarkably, there were no significant differences observed in postoperative knee function between the well- and poorly-reduced groups, indicating that both groups achieved favorable outcomes.

Acute distal patella tendon avulsion from the tibial tubercle (TT) is a relatively rare injury that is usually described in the adolescents or elderly population in their 7 or 8 decades. Bifocal avulsion fractures of the patella tendon from the TT and the distal pole of the patella are exceptionally rare in adults. In this case report, we present a 52-year-old healthy old male who was treated for bifocal avulsion of the patellar tendon with open reduction and internal fixation augmented with two ULTRATAPE sutures. To our knowledge, this is the first case report to describe this injury in a healthy middle-aged patient.

DESIGN
Systematic review.
REVIEW QUESTION
Does splinting of traumatised primary teeth improve clinical outcomes?
CASE SELECTION
Clinical studies published after 2003 reporting trauma (luxation, root fracture or alveolar fracture) to primary teeth, with a minimum follow-up of 6 months, were eligible for inclusion. Case reports were excluded, but case series were included. Studies reporting the outcome of splinting following avulsion injuries were excluded, as current guidance does not recommend re-implantation of teeth for these injuries.
DATA ANALYSIS
Two researchers independently assessed the risk of bias in the included studies, with a third researcher resolving any disagreements. The same two independent researchers conducted a quality assessment of the included studies.
RESULTS
Three retrospective studies met the inclusion criteria. Only one of these studies had a control group. High success rates were reported for the management of teeth with root fractures. A benefit for splinting teeth with lateral luxation was not identified. No alveolar fractures were included.
CONCLUSIONS
This review suggests that the outcome of the management of root fractures in primary teeth may benefit from flexible splinting. However, the evidence base is low.

INTRODUCTION
Posterior cruciate ligament (PCL) avulsion fractures are the most common type of isolated PCL injuries. Avulsion from the tibia is more common than femoral attachment. They can present as isolated tibial avulsion or as a component of posterior tibial rim fractures. The size, geometry of the fragment, and associated ligamentous injury dictate the method of fixation.
CASE REPORT
A 32-year-old patient presented with posterior rim tibial plateau fracture with PCL avulsion after a motor vehicle accident. We used Burke and Schaffer approach and fixed the ligamentous avulsion and rim fracture using high tensile sutures and knotless swivel lock anchors.
CONCLUSION
PCL avulsions can present either as an isolated injury or as a part of a complex injury involving the anterior or posterior tibial rim. These complex injuries occur due to the hyperextension mechanism which results in either anterior tibial plateau compression fracture or posterior rim avulsion injuries. The treatment of such injuries requires addressing both ligamentous and bony components. The size, geometry of the fragment, and associated ligamentous injury dictate the method of fixation. We described the fixation of both ligamentous and rim avulsion using sutures and knotless anchors.

BACKGROUND
Acute closed volar plate injury of the proximal interphalangeal joint (PIP) is a common hand injury. In the past, there were few objective evaluation imaging methods for the degree of volar plate injury. The purpose of this study was to investigate the role of high frequency ultrasonography in diagnosing volar plate injury, and to explore whether ultrasound can provide a beneficial guidance to clinical decision-making and appropriate treatment adopting through accurate US classification of volar plate injury.
METHODS
From May 2019 to may 2022, 41 patients diagnosed with volar plate injury were included in this study. All patients underwent ultrasonography and X-ray examinations. The sonographic features were analyzed. A new kind of classification of volar plate injury based on ultrasonography findings was described.
RESULTS
Either an injury of volar plate or an avulsion fracture of middle phalangeal base was identified clearly on ultrasonography, according to which volar plate injury could be divided into three types: A, B and C. Type A, avulsion fracture of the middle phalangeal base without volar plate rupture; Type B, full thickness tear of the volar plate without avulsion fracture; Type C, partial thickness tear of the volar plate. The average thickness of the three types of injured volar plate measured by ultrasound was 0.33 ± 0.05 cm, and the average thickness of the volar plate at the same site of the corresponding finger on the contralateral side was 0.22 ± 0.03 cm. There was significant difference between the two group (t = 11.823, p = 1.2476 *10^(-14)).
CONCLUSIONS
High frequency ultrasonography could be a reliable, accurate, convenient and non-radioactive diagnostic imaging technique in the evaluation of acute closed volar plate injury of PIP. And ultrasound could provide a beneficial guidance to clinical decision-making and appropriate treatment adopting through accurate US classification.
