Hook plate fixation and tension band wiring in the treatment of Mayo type II olecranon fractures.

Background: Olecranon fractures account for 8 ∼ 10% of all elbow fractures and usually require surgical intervention. Tension band wiring (TBW) is considered as the standard treatment while it is associated with high re-operation rates.

Objective: This study aims to compare the functional outcomes, complications and re-operations of hook plate fixation (HPF) versus TBW in treating Mayo Type II olecranon fractures.

Removal of Forearm Plate Leads to a Higher Risk of Refracture-A Systematic Review and Meta-Analysis.

Objective: Plate fixation is the preferred method for treating forearm shaft fractures. However, it remains controversial regarding the necessity of implant removal after bone union. This review aims to assess refracture risk after plate removal.

Three-dimensional quantitative study and functional outcome analysis of coronoid fracture in different elbow injury patterns.

Background: Coronoid fractures are often part of a complex fracture-dislocation of the elbow. For an optimum prognosis, it is important to understand the characteristics of coronoid fractures in different elbow injury patterns. Significant differences in these characteristics have been observed in various studies, but these previous studies have suffered from limitations, such as insufficient quantification and unknown prognostic differences among different injury patterns.

Clinical outcomes of olecranon sled fixation in patients with Mayo type II olecranon fractures.

Background: Tension band wiring and plate fixation are common internal fixation methods used for olecranon fractures, but complications and reoperations are common. The purpose of this study is to investigate the clinical outcomes of displaced olecranon fractures treated with olecranon sled internal fixation.

Methods: The data of 39 patients with olecranon fractures treated with olecranon sled in the Department of Traumatology of Beijing Jishuitan Hospital between May 2018 and April 2020 were retrospectively analyzed.

Anxiety and depression are associated with poor outcomes in open elbow arthrolysis.

Background: Open elbow arthrolysis (OEA) is an established treatment for posttraumatic elbow stiffness (PTES); however, its efficacy is debatable for some patients. Poor surgical outcomes have been associated with anxiety and depression in other orthopedic conditions, but no studies have examined this association in OEA. In this study, we aimed to determine whether a high preoperative anxiety and depression score is associated with a worse functional outcome in OEA for PTES.

Biomechanical comparison of three internal fixation configurations for low transcondylar fractures of the distal humerus.

Background: We aimed to evaluate the biomechanical stiffness and strength of different internal fixation configurations and find suitable treatment strategies for low transcondylar fractures of the distal humerus.

Methods And Materials: Thirty 4 generation composite humeri were used to create low transcondylar fracture models that were fixed by orthogonal and parallel double plates as well as posterolateral plate and medial screw (PPMS) configurations (n=10 in each group) using an anatomical locking compression plate-screw system and fully threaded medial cortical screws. Posterior bending (maximum 50 N), axial loading (maximum 200 N) and internal rotation (maximum 10 N·m) were tested, in that order, for each specimen.

Relationship between measurements of ipsilateral capitellum and prosthetic radial head size.

Background: Selecting the correct size of head component is challenging in radial head arthroplasty, particularly in comminuted fractures. This study aimed to investigate the relationship between measurements of the ipsilateral capitellum and the prosthetic radial head size, which may be used to predict the size of the radial head prosthesis preoperatively.

Methods: Our study enrolled all patients who underwent radial head arthroplasty at Beijing Jishuitan Hospital.

Comparative study of functional outcomes between OTA/AO type C, Gustilo type I/II open fractures and closed fractures of the distal humerus treated by open reduction and internal fixation.

Background: To evaluate the difference of functional outcomes between OTA/AO type C, Gustilo type I/II open fractures and closed fractures of the distal humerus after open reduction and internal fixation.

Methods: We retrospectively analyzed the clinical data of patients with OTA/AO-C distal humerus fractures who were treated in our department from January 2014 to December 2016. The patients were divided into an open fracture group and a closed fracture group.

Comparative study of the functional outcomes of combined medial-lateral approach arthrolysis with or without external fixation for severe elbow stiffness.

Background: To evaluate and compare the functional outcomes of combined medial-lateral approach open arthrolysis with and without hinged external fixation.

Methods: We retrospectively collected and analyzed the clinical data of patients with severe elbow stiffness who were treated in our institution from January 2018 to January 2019. All of them were treated with combined medial-lateral approach arthrolysis.

Lateral minimal approach to the terrible triad of the elbow: a treatment protocol in Beijing Jishuitan Hospital.

Background: This study aimed to report the surgical techniques and results of treating coronoid process and radial head fracture combined with dislocation of the elbow (terrible triad of the elbow) using a single lateral incision, known as the extensor digitorum communis (EDC) split approach.

Methods: A retrospective analysis was performed of 109 patients with terrible triad of the elbow who had been treated by the authors from January 2013 to December 2019. The participants included 67 males and 42 females, with a mean age of 42.

Chronic type C3 distal humeral fracture associated with massive bone defects treated by open reduction and internal fixation with iliac crest autografts: a case report.

Background: Chronic intercondylar fractures of the distal humerus with massive bone defects and severe comminution in the metaphysis are rare and complex injuries that are challenging for surgeons to treat, as reconstructing the triangular structure of the distal humerus is difficult and may have a severe impact on functional outcomes, especially in young patients, for whom total elbow arthroplasty is usually not a suitable option due to significant impairment in upper limb strength. Here, we report a patient in such scenario who was young and active and was treated by structural iliac bone autografting and internal fixation.

Case Presentation: A 26-year-old male patient experienced a major car accident and was diagnosed with an open fracture (Gustilo-Anderson type IIIB) of the right distal humerus with massive bone defects and severe intra-articular involvement, without neurovascular injuries or other associated injuries.

Olecranon osteotomy vs. triceps-sparing for open reduction and internal fixation in treatment of distal humerus intercondylar fracture: a systematic review and meta-analysis.

Background: The open reduction and internal fixation (ORIF) was a standard treatment approach for fracture at distal humerus intercondylar, whereas the optimal way before ORIF remains inconclusive. We, therefore, performed a systematic review and meta-analysis to assess the efficacy and safety of olecranon osteotomy vs. triceps-sparing approach for patients with distal humerus intercondylar fracture.

Robot-assisted S2 screw fixation for posterior pelvic ring injury.

Background: Percutaneous sacroiliac screw is one of the main methods to treat unstable posterior pelvic ring injury. However, complexity of pelvic anatomical structure increases the difficulty and risk with freehand operation. Besides, S2 screw fixation began to receive attention.

Changes in bone mineral density after parathyroidectomy in patients with moderate to severe primary hyperparathyroidism.

Objective: Primary hyperparathyroidism (PHPT) is relatively common in China and results in severe damage to the skeletal system. This study aimed to investigate changes in bone mineral density (BMD) over 2 years in patients with PHPT after parathyroidectomy.

Methods: This retrospective cohort study included patients with PHPT who underwent parathyroidectomy between January 2010 and December 2015.

Identification of independent factors affecting bone mineral density after successful parathyroidectomy for symptomatic hyperparathyroidism.

Background: Studies have shown that the response of bone mineral density (BMD) to parathyroidectomy for symptomatic primary hyperparathyroidism (PHPT) is heterogeneous and difficult to predict. However, the independent factors affecting BMD in PHPT patients after parathyroidectomy remains limited and inconclusive. This study aimed to explore the independent factors affecting BMD changes in symptomatic PHPT patients after parathyroidectomy.

Correlation between modified trochleocapitellar index and post-traumatic elbow stiffness in type C2-3 distal humeral fractures among adults.

Background: The purpose of this study was to propose the modified trochleocapitellar index (mTCI), assess its reliability, and evaluate its correlation with post-traumatic elbow stiffness in type C2-3 distal humeral fractures among adults.

Methods: From January 2013 to June 2017, a total of 141 patients with type C2-3 distal humeral fractures were included. The mTCI was calculated as the ratio between the modified trochlear and capitellar angles relative to the humeral axis (mTCI-HA), lateral humeral line (mTCI-LHL), and medial humeral line (mTCI-MHL) from anteroposterior radiographs taken immediately after the operation.

[Progress on diagnosis and treatment of low transcondylar fractures of distal humerus].

Low transcondylar fractures of the distal humerus in adults is rarely seen and reported in literatures. It has a bimodal distribution in terms of age, affecting the elderly and younger patients. The fracture is characterized by a very low transverse intra-capsular and extra-articular fracture lines extending from the level of lateral epicondyle to medial epicondyle.

Retrospective analysis of 514 cases of tibial plateau fractures based on morphology and injury mechanism.

Background: Tibial plateau fractures remain a clinical challenge due to the complexity of the fracture patterns which have been repeatedly categorized by many researchers. However, limitations do exist in some respects. So we aimed to reclassify tibial plateau fractures based on injury mechanism and morphological characteristics.
