OBJECT: Evaluation of the impact of patients' participation on postoperative recovery and satisfaction who underwent the Percutaneous Endoscopic Interlaminar Discectomy(PEID). METHODS: We collected data from sixty-nine patients who underwent PEID surgery at Chuzhou Chinese and Western Medicine Hospital between January 2020 and December 2022. All patients had L5/S1 lumbar disc herniation and met the inclusion and exclusion criteria. The patients were divided into two groups: non-communication group (n = 33) and communication group (n = 36)...

OBJECTIVE: The effectiveness and safety of fibular intramedullary nail fixation (FINF) compared to plate fixation (PF) in treating ankle fractures among adults remains unclear. Therefore, we conducted a meta-analysis to assess the efficacy and safety of FINF versus PF, aiming to provide orthopedic surgeons with valuable insights when choosing between the two internal fixation methods for patient treatment. METHODS: PubMed, EMBASE, and SCOPUS were systematically searched for articles comparing FINF and PF in ankle fractures among adults...

BACKGROUND: In acetabular fracture surgery, understanding the biomechanical behaviour of fractures and implants is beneficial for clinical decision-making about implant selection and postoperative (early) weightbearing protocols. This study outlines a novel approach for creating finite element models (FEA) from actual clinical cases. Our objectives were to (1) create a detailed semi-automatic three-dimensional FEA of a patient with a transverse posterior wall acetabular fracture and (2) biomechanically compare patient-specific implants with manually bent off-the-shelf implants...

BACKGROUND: Radial head fractures are the most common bony injury of the elbow in adults. The current literature does not agree on whether isolated stable type II radial head fractures should be treated operatively or nonoperatively. This review aims to determine the preferred treatment for Mason type II radial head fractures and compare the outcomes of conservative and surgical treatment. METHODS: Our study used PRISMA guidelines and conducted a thorough search of multiple electronic databases, including PubMed, Cochrane, Embase, Web of Science, CNKI, and Wanfang databases, initially identifying 545 relevant publications on surgical and conservative treatment of Mason type II radial head fractures...

BACKGROUND: Machine learning (ML) is extensively employed for forecasting the outcome of various illnesses. The objective of the study was to develop ML based classifiers using a stacking ensemble strategy to predict the Japanese Orthopedic Association (JOA) recovery rate for patients with degenerative cervical myelopathy (DCM). METHODS: A total of 672 patients with DCM were included in the study and labeled with JOA recovery rate by 1-year follow-up. All data were collected during 2012-2023 and were randomly divided into training and testing (8:2) sub-datasets...

This literature review examines the impact of orthopaedic trauma on patient mental health. It focuses on patient outcomes, available resources, and healthcare provider knowledge and education. Orthopaedic trauma represents a significant physical and psychological burden for patients, often resulting in long-term disability, pain, and functional limitations. Understanding the impact of orthopaedic trauma on patient mental health is crucial for improving patient care, and optimizing recovery and rehabilitation outcomes...

BACKGROUND: Posterolateral decompression and fusion with internal fixation is a commonly used surgical approach for treating degenerative lumbar spinal stenosis (DLSS). This study aims to evaluate the impact of preserving a portion of the unilateral facet joint during decompression on surgical outcomes and long-term recovery in patients. METHODS: This study analyzed 73 patients with DLSS accompanied by bilateral lower limb neurological symptoms who underwent single-level L4/5 posterolateral decompression and fusion surgery from January 2022 to March 2023...

BACKGROUND: Severe kyphosis is a common condition in patients with advanced ankylosing spondylitis (AS). Although two-level osteotomy may serve as a potential alternative, it is often associated with increased blood loss and elevated surgical risks. To date, the optimal treatment for the challenging condition remains unclear. This study aims to introduce an effective strategy for the treatment of severe kyphosis secondary to AS, using one-level modified osteotomy combined with shoulders lifting correction method...

OBJECTIVE: To investigate in vivo 6-degree-of-freedom (DOF) vertebral motion in patients with isthmic spondylolisthesis (IS) during various functional weight-bearing activities. METHODS: Fifteen asymptomatic volunteers (mean age 54.8 years) and fourteen patients with IS at L4-5 (mean age 53.4 years) were recruited. The positions of the vertebrae (L4-L5) in the supine, standing, flexion-extension, left-right twisting and left-right bending positions were determined using previously described CT-based models and dual fluoroscopic imaging techniques...

Degenerative disc disease is the leading cause of lower back and leg pain, considerably impacting daily life and incurring substantial medical expenses for those affected. The development of annulus fibrosus tissue engineering offers hope for treating this condition. However, the current annulus fibrosus tissue engineering scaffolds fail to accurately mimic the natural biological environment of the annulus fibrosus, resulting in limited secretion of extracellular matrix produced by the seeded cells and poor biomechanical properties of the constructed biomimetic annulus fibrosus tissue...

BACKGROUND: Large spacers offer numerous advantages such as higher fusion rates and lower subsidence rates. However, due to the anatomical constraints of the approach, the use of large spacers in biportal endoscopic transforaminal lumbar interbody fusion(BE-TLIF) necessitates an additional incision and special instruments for spacer implantation leading to less frequent use. METHODS: This study has refined several techniques within BE-TLIF. We insert the cage and impact the cage transverse with a special design instrument in the same working portal...

BACKGROUND: The reconstruction of complex wounds of the hand still has challenges in achieving aesthetic, functional and sensory recovery. We presented our experience of using the polyfoliate and chimeric radial collateral artery perforator flaps (RCAPF) to repair complex hand defects, aiming to explore the feasibility of special-form RCAPFs in hand coverage and enhance the comprehension of their respective indications. METHODS: From June 2014 to March 2021, 26 cases (19 males and 7 females, mean 44...

BACKGROUND: Bone loss caused by microgravity exposure presents a serious threat to the health of astronauts, but existing treatment strategies have specific restrictions. This research aimed to investigate whether salidroside (SAL) can mitigate microgravity-induced bone loss and its underlying mechanism. METHODS: In this research, we used hindlimb unloading (HLU) and the Rotary Cell Culture System (RCCS) to imitate microgravity in vivo and in vitro. RESULTS: The results showed that salidroside primarily enhances bone density, microstructure, and biomechanical properties by stimulating bone formation and suppressing bone resorption, thereby preserving bone mass in HLU rats...

BACKGROUND: Bone defects, especially critical-size bone defects, and their repair pose a treatment challenge. Osteoinductive scaffolds have gained importance given their potential in bone tissue engineering applications. METHODS: Polycaprolactone (PCL) scaffolds are used for their morphological, physical, cell-compatible and osteoinductive properties. The PCL scaffolds were prepared by electrospinning, and the surface was modified by layer-by-layer deposition using either graphene or graphene oxide...

INTRODUCTION: Primary total elbow replacement (TER) services in England are being restructured with the goal of centralising care to specialised centres. It is important to monitor the impact of this service redesign. This protocol outlines an intended analysis to provide detailed descriptions of the patients who are receiving primary TER, where and by whom TER is being performed, and what the current surgical practices for TER are in England before the reconfiguration. METHODS: This analysis will use the National Joint Registry (NJR) elbow dataset and link it with NHS England Hospital Episode Statistics-Admitted Patient Care (HES-APC)...

BACKGROUND: A corrective radius osteotomy is often performed in patients with a symptomatic distal radius malunion. In 3D-planned osteotomies, the unaffected radius is mirrored over the malunited radius after adjusting for left-right length differences using both ulnae. This approach assumes that ulnar length differences in a malunion population are similar to those in a healthy population. This study was conducted to analyze the difference in ulnar length in a distal radius malunion population and to assess the potential influence of age, sex, or malunion side on this difference...

BACKGROUND: Commercially available osseointegrated devices for transfemoral amputees are limited in size and thus fail to meet the significant anatomical variability in the femoral medullary canal. This study aimed to develop a customized osseointegrated stem to better accommodate a variety of femoral anatomies in transfemoral amputees than off-the-shelf stems. Customization is expected to enhance cortical bone preservation and increase the stem-bone contact area, which are critical for the long-term stability and success of implants...
