New technology: clinical efficacy of intracapsular decompression and supported hollow screw treatment for Garden IV femoral neck fractures.

The management of Garden IV femoral neck fractures presents a formidable challenge. This study aimed to assess the safety and efficacy of a novel technological approach for treating Garden IV femoral neck fractures, involving intracapsular decompression and the utilization of supported hollow screws. Between October 2018 and October 2021, a cohort of 46 patients, comprising 25 males and 21 females, was admitted for Garden IV femoral neck fractures. The surgical intervention employed a novel methodology, involving closed reduction of femoral neck fractures on a traction bed and percutaneous implantation of decompression support hollow screw internal fixation in the capsule. Operative parameters such as intraoperative bleeding volume, incision length, and fluoroscopy frequency were recorded. Postoperative angiography was performed to evaluate the blood supply to the femoral neck and femoral head, while long-term follow-up records documented femoral neck fracture healing and patient functional recovery. The closed reduction and minimally invasive implantation of decompression support screws in the femoral neck capsule proved effective in successfully fixing Garden IV femoral neck fractures. The screw placement time was 20-45min, with an average of 25.2min. The number of fluoroscopy was 6-14, with an average of 7. The postoperative follow-up was 20-25months, with an average duration of 22months. All patients exhibited uneventful single-stage wound healing, devoid of complications such as nerve, blood vessel, or important tissue structure injuries. While femoral head necrosis occurred in one case and femoral neck shortening in another, all femoral neck fractures exhibited healing. Post-surgery, patients experienced rapid recovery, enabling early functional exercise with satisfactory functional restoration. The innovative technology, employing femoral neck capsule decompression support hollow screws, not only offers structural support, but also facilitates capsule decompression post-femoral neck fracture surgery. This approach promotes the restoration of blood flow to the femoral head and neck, accelerates fracture healing, diminishes the likelihood of femoral head necrosis, and enhances the overall therapeutic outcome for Garden IV femoral neck fractures. The merits of this novel technique warrant its widespread adoption and application.

Total knee arthroplasty combined with simultaneous open reduction and internal fixation in the treatment of knee osteoarthritis with patellar fracture: a case report and review of the literature

BackgroundPatients with severe knee osteoarthritis combined with patellar fracture are rare, and it is unclear whether single-stage surgery affects the enhanced recovery after surgery.Case presentationThis case report describes two patients of Han nationality. A 69-year-old male patient was previously diagnosed with severe knee osteoarthritis of the left knee joint and was treated conservatively with long-term oral nonsteroidal antiinflammatory drugs and intraarticular injection of sodium hyaluronate. He was hospitalized for acute left knee injury owing to a fall from a height. He was diagnosed with knee osteoarthritis of the left knee joint and patellar fracture. Another 74-year-old female patient was previously diagnosed with severe knee osteoarthritis, long-term oral nonsteroidal antiinflammatory drugs and topical Chinese medicine to relieve the pain. A month ago, she fell down the stairs and fractured the patella in her left knee, she was diagnosed with severe left knee osteoarthritis combined with an old left patella fracture. Both patients were successfully treated by single-stage primary total knee arthroplasty and fixation of the patellar fracture. They both carried out early functional exercise normally and successfully achieved enhanced recovery.ConclusionSuccessful single stage total knee replacement with patella management can not only reduce the number of operations, but also enable patients to achieve rapid postoperative recovery. However, single stage may increase the risk of local surgical complications. Therefore, for most patients, especially those with low risk of anesthesia related complications, standard of treatment remains first fixing the patellar fracture and when the fracture is healed proceed with the total knee arthroplasty.

Treatment of proximal phalangeal fracture with miniature combined external fixator

To investigate the clinical effect of limited open reduction treatment of proximal phalangeal fracture with miniature external fixator combined with small incision. Between January 2020 and December 2022, 29 patients with proximal phalangeal fracture were treated with micro external fixator combined with small incision in fracture plane, including 23 males and 6 females, aged from 19 to 62 years old with an average of (36.2±21.0) years old. Five patients with open phalangeal fracture were treated with stageⅠsurgery, 24 cases of closed phalangeal fracture were treated with elective surgery. At the 6 month follow-up, the curative effect was evaluated according to the total active flexion scale (TAFS) of the American Hand Surgery Association. The fracture healing, nail path, local soft tissue healing, and complications were observed. All the 29 patients were followed up for 6 to 10 months with an average of(8.3±2.1) months, 3 patients had delayed fracture healing, 1 patient had distal skin numbness, symptoms were relieved after nutritional nerve treatment, no external fixator broken nails, no infection, the nail path and small incision healing was good, bone healing was achieved at the end of follow-up. Fracture healing time ranged from 10 to 24 with an average of (13.7±3.1) weeks. Six months after operation, according to the TAFS standard, 19 cases (227.68±4.23) were excellent, 7 cases (203.86±14.32) were good, and 3 cases (170.33±7.32) were poor. The micro-combined external fixator combined with limited incision with small incision can be used in the treatment of proximal phalangeal fracture. The operation is simple and beneficial to early functional exercise, small extensor tendon irritation, convenient second-stage removal, and high rate of excellent and good functional score in recovery period.

Effects of early mobilization in elderly patients undergoing cardiac surgery.

Although early mobilization is associated with improved outcomes in postoperative cardiac patients, implementation of early mobilization in elderly patients is still a challenge. In this study, we aimed to design and assess an early mobilization program for cardiac rehabilitation. We conducted a clinical trial in elderly patients aged over 65years after coronary artery bypass graft surgery. Patients were randomly assigned to an early mobilization group (Group A) or a routine therapy group (Group B). Short-Form International Physical Activity Questionnaire (SF-IPAQ), to assessment balance Time Up and Go (TUG), to assessment functional capacity the 2-min walking test (2MWT) and the short physical performance battery (SPPB) were used as a reference to formulate and monitor the early mobilization regimen. A total of 100 patients were enrolled (n = 50 per group). The mean walking distance in Group A was significantly higher at 135.6 ± 9.29 than the mean walking distance in Group B which was lower at 123.4 ± 8.48. Also, the patients in Group B had a mean SF-IPAQ of 389.44 with an SD of 85.7, P < 0.001, whereas the mean SF-IPAQ amount in Group A was 556.16 with an SD of 91.47. In early mobilization group, a strong positive connection was indicated by the correlation coefficient of r = 0.957 between the amount of SF-IPAQ and 2 MWT and there was a significant negative association r = - 0.768 between 2MWT and TUG. Our study's findings suggest that early mobilization and functional exercises enhanced balance, functionality, and life quality for older cardiac patients.

Technical modifications to elbow interposition arthroplasty

Interposition arthroplasty of the elbow involves the interposition of afascia lata or dermis autograft or allograft between the distal humerus and the ulna or radius, while preserving the original form of articulation. Interposition arthroplasty is indicated for young patients with high functional demands who suffer from end-stage elbow arthritis and associated pain or joint stiffness. Contraindications include acute or subacute infection, skeletal immaturity, bone loss, deformity, or gross instability. Once the ulnar nerve has been secured, joint access is established via aposterior approach. The radial collateral ligament (RCL) and the common extensor tendon origin (CEO) are detached, while preserving the anconeus muscle and the lateral ulnar collateral ligament (LUCL). Subsequently, a capsular release is required to maintain adequate joint exposure and address the accompanying stiffness. Three to four transosseous drill holes are placed at the level of the distal humerus to secure the graft. After the graft has been positioned successfully within the joint space using two guide sutures, it can be secured to the distal humerus using ahorizontal mattress stitch. Finally, the detached tendon and ligament structures are reconstructed. After initial immobilization, early functional exercise of the elbow is performed in the motion orthosis, avoiding valgus or varus stress. The efficacy of elbow interposition arthroplasty has been demonstrated, particularly for young and active patients with severe inflammatory or post-traumatic osteoarthritis. Despite the results in terms of postoperative function and pain reduction are satisfactory, the current literature reports high complication, subsequent treatment, and revision rates. In the event of interposition arthroplasty failure, revision with another interposition procedure or conversion to endoprosthesis may be considered.

Functional assessment and influencing factors after staged functional training in patients with ankle fractures.

The recovery of limb function after ankle fracture surgery is a gradual process. The main purpose of implementing early functional exercise, joint mobility, muscle contraction function, passive ankle flexion and extension exercises, or physical factor therapy techniques is to achieve the rapid recovery of normal physiological limb function. However, currently the most effective rehabilitation training method is staged limb functional exercise, which promotes rapid recovery of limb function while preventing adverse consequences caused by overwork or insufficient training. Staged limb functional exercise divides the rehabilitation process into multiple stages, each of which has specific training objectives and contents. This method helps patients gradually restore limb function. Nevertheless, some patients still exhibit poor limb function after standardized exercise. Therefore, a functional evaluation should be performed to analyze the impact of staged functional training after ankle fracture surgery. To perform a functional evaluation and determine the influencing factors of staged functional training in patients with ankle fracture. A retrospective study enrolled 150 patients who underwent surgical treatment for ankle fracture from May 2020 to May 2022 at our hospital. Univariate and multivariate linear regression analyses were performed on general data, functional exercise compliance scale for orthopedic patients, Social Support Rating Scale (SSRS), American Orthopedic Foot and Ankle Score (AOFAS) Ankle-Hindfoot Score, and pain factors [serum bradykinin (BK), prostaglandin E2 (PGE2), 5-hydroxytryptamine (5-HT)]. Based on the AOFAS Ankle-Hindfoot Scale, the cases were divided into the excellent function (n = 111) and ordinary function (n = 39) groups. Univariate analysis revealed that monthly family income, education level, diabetes mellitus, functional exercise compliance scale of orthopedic patients score, SSRS, BK, PGE2, and 5-HT significantly influenced limb function after ankle fracture (P < 0.05); Multiple linear regression analysis showed that the functional exercise compliance scale score, SSRS, BK, PGE2, and 5-HT were independent risk factors affecting functional performance after staged functional exercise (P < 0.05). Exercise compliance, SSRS, and pain level are the independent risk factors affecting functional performance after staged functional training following ankle surgery. Clinical nursing care after ankle surgery should include analgesic and health education measures to ensure optimal recovery of limb function.

Enhanced Outcomes in Femoral Subtrochanteric Fractures Using Long INTERTAN Nails with Titanium Cable Cerclage: A Retrospective Analysis.

BACKGROUND The evidence on use of supplementary titanium cable cerclage (TCC) in treating femoral subtrochanteric fractures (FSF) remains scarce. Therefore, this study aimed to investigate the potential therapeutic effects for FSF patients using TCC. MATERIAL AND METHODS A retrospective study of 68 FSF patients treated by a long intramedullary (IM) nailing with (Observation group, n=41) or without (Control group, n=27) TCC was conducted from January 2020 to December 2021. The primary outcome measure was time to postoperative full weight-bearing. Secondary outcome measures were operation time, intraoperative blood loss, number of blood transfusions needed, varus angle loss, excellent and good rate of fracture reduction, Harris score, and survival rate. RESULTS Patients were followed up for 13 to 36 months. The excellent and good rate of fracture reduction was 100% in the Observation group versus 92.6% in the Control group (P=0.013), and the varus angle loss and time to postoperative full weight-bearing in the Observation group were significantly less than in the Control group (P<0.05). The intraoperative blood loss in the Observation group was significantly higher than in the Control group (P<0.001). No differences were noted between groups for Harris scores and survival rates at last follow-up. CONCLUSIONS TCC fixation combined with IM nailing can improve the excellent and good rate of fracture reduction and reduce varus angle loss, as well as shorten the time to full weight-bearing and promote early functional exercise, which offers an effective treatment option for FSF patients who have failed closed reduction.

Management of infected bone defects of the femoral shaft by Masquelet technique: sequential internal fixation and nail with plate augmentation

BackgroundTo evaluate the effectiveness of a sequential internal fixation strategy and intramedullary nailing with plate augmentation (IMN/PA) for bone reconstruction in the management of infected femoral shaft defects using the Masquelet technique.MethodsWe performed a retrospective descriptive cohort study of 21 patients (mean age, 36.4 years) with infected bone defects of the femoral shaft treated by the Masquelet technique with a minimum follow-up of 18 months after second stage. After aggressive debridement, temporary stabilisation (T1) was achieved by an antibiotic-loaded bone cement spacer and internal fixation with a bone cement–coated locking plate. At second stage (T2), the spacer and the locking plate were removed following re-debridement, and IMN/PA was used as definitive fixation together with bone grafting. We evaluated the following clinical outcomes: infection recurrence, bone union time, complications, and the affected limb’s knee joint function.ResultsThe median and quartiles of bone defect length was 7 (4.75–9.5) cm. Four patients required iterative debridement for infection recurrence after T1. The median of interval between T1 and T2 was 10 (9–19) weeks. At a median follow-up of 22 (20–27.5) months, none of the patients experienced recurrence of infection. Bone union was achieved at 7 (6–8.5) months in all patients, with one patient experiencing delayed union at the distal end of bone defect due to screws loosening. At the last follow-up, the median of flexion ROM of the knee joint was 120 (105–120.0)°.ConclusionsFor infected femoral shaft bone defects treated by the Masquelet technique, sequential internal fixation and IMN/PA for the reconstruction can provide excellent mechanical stability, which is beneficial for early functional exercise and bone union, and does not increase the rate of infection recurrence.

Exploring the Relationship Between Subcutaneous Fat Index and Neck Pain in Patients with Spinal Cervical Spondylosis: A Retrospective Cohort Study

Retrospective Cohort Study. This study measures the subcutaneous fat index (SFI) of the cervical spine in patients with spinal cervical spondylosis using cervical magnetic resonance imaging and explores its relationship with neck pain in patients with spinal cervical spondylosis. In this single-center retrospective study, 298 patients hospitalized for spinal cervical spondylosis between January and June 2021 were initially considered. After applying inclusion and exclusion criteria, 93 patients were enrolled. The cervical magnetic resonance imaging data for these patients were analyzed using A-Site software. The SFI was measured at the median sagittal plane on T2-weighted images. Patients were categorized into 2 groups based on their admission complaints: those with cervical pain and those without it. Differences between these groups were then statistically analyzed. The mean SFIs with standard deviations for the neck and non-neck pain groups were 36.4%±7.7% and 27.0%±7.9%, respectively, with a significant difference (P < 0.0001). The SFI was consistently higher across all neck segments in the neck pain group compared to the nonneck pain group (P < 0.05). The 2 groups had no statistically significant difference in the body mass index. The SFI provides a more precise assessment of muscle and fat distribution in the posterior cervical region than body mass index and is generally higher in patients with spinal cervical spondylosis who experience neck pain. These findings suggest the importance of early functional exercises postsurgery for potentially improving surgical outcomes in this patient population.

Progress of ultrasound-guided nerve block in foot and ankle arthroscopy

Foot and ankle arthroscopy frequently results in severe perioperative swelling and pain. The ultrasound-guided nerve block technique stands out for its ability to offer reliable and potent pain relief. This technique not only promotes early functional exercise, but also realizes enhanced recovery after surgery, which has demonstrated significant advantages in the realm of foot and ankle arthroscopy. In recent years, blocking techniques targeting different nerve planes have been reported to expand the options available for clinical use. This article primarily describes the current application of foot and ankle arthroscopy, detailing various local nerve blocks under innervation and ultrasound guidance. By doing so, this review intends to provide insights for the selection of clinical anesthesia in foot and ankle arthroscopy.

Effectiveness comparison of a new hook-shaped anatomical locking plate and conventional anatomical locking plate in treatment of Danis-Weber type A lateral malleolus fractures

To investigate the effectiveness of a new hook-shaped anatomical locking plate in the treatment of Danis-Weber type A lateral malleolus fractures. A retrospective analysis was performed on the clinical data of 45 patients with Danis-Weber type A lateral malleolus fractures who met the selection criteria between November 2020 and November 2022. According to the surgical methods, they were divided into the observation group (treated with the new hook-shaped anatomical locking plate, 23 cases) and the control group (treated with the conventional lateral malleolus anatomical locking plate, 22 cases). There was no significant difference in baseline data such as gender, age, cause of injury, Danis-Weber type of fracture, time from injury to operation, and combined ligament injury between the two groups ( P>0.05). The operation time, partial weight-bearing time, return to work time, and postoperative complications were recorded and compared between the two groups. The function and pain of ankle joint were evaluated by the range of motion of ankle dorsiflexion, plantarflexion, varus, valgus, and visual analogue scale (VAS) score at 1 and 3 months after operation, and at last follow-up, and the American Orthopaedic Foot and Ankle Society (AOFAS) score at 3 months after operation and at last follow-up. All patients were followed up 10-18 months (mean, 15.1 months). There was no significant difference in operation time between the two groups ( P>0.05); the postoperative partial weight-bearing time and return to work time of the observation group were significantly earlier than those of the control group ( P<0.05). During the follow-up, there was 1 case of joint stiffness in the observation group, and 1 case of joint surface displacement, 1 case of joint stiffness, and 1 case of traumatic arthritis in the control group. There was no significant difference in the incidences of complications between the two groups ( P>0.05). With the extension of time after operation, the range of motion of ankle dorsiflexion, plantarflexion, varus, valgus, and VAS score of the two groups gradually improved, and there were significant differences between different time points ( P<0.05); At 1 and 3 months after operation, the above indexes in the observation group were significantly better than those in the control group ( P<0.05), and there was no significant difference between the two groups at last follow-up ( P>0.05). The difference of AOFAS score between the last follow-up and 3 months after operation in the observation group was significantly better than that in the control group ( P<0.05). Compared with the conventional lateral malleolus anatomical locking plate, the new hook-shaped anatomical locking plate has a more reliable fixation effect in the treatment of Danis-Weber type A lateral malleolus fracture, which is conducive to early functional exercise of the ankle joint, so that patients can bear weight earlier and return to work earlier, and the operation time is not significantly prolonged, and the effectiveness is satisfactory.

Comparison of effectiveness of three surgical methods in treatment of Pauwels type Ⅲ femoral neck fracture in young and middle-aged patients

To compare the effectiveness of three surgical methods in the treatment of Pauwels type Ⅲ femoral neck fracture in young and middle-aged patients, in order to provide reference for clinical selection of appropriate surgical methods. The clinical data of 103 patients with Pauwels type Ⅲ femoral neck fracture who met the selection criteria between June 2018 and December 2021 were retrospectively analyzed. The fractures were fixed with hollow screws in an inverted triangular shape (37 cases, hollow screw group), hollow screws in an inverted triangular shape combined with eccentric shaft screw (34 cases, eccentric shaft screw group), and hollow screws in an inverted triangular shape combined with medial support plate (32 cases, support plate group). There was no significant difference in age, gender, cause of injury, body mass index, time from injury to operation, side of the fracture, and Garden classification, whether they were in traction preoperatively, and other baseline data between groups ( P>0.05). The operation time, intraoperative blood loss, the number of fluoroscopy, the length of hospital stay, early postoperative complication and postoperative weight-bearing time of the three groups were recorded. Harris score was used to evaluate joint function at 6 and 12 months after operation, and the difference between the two time points (change value) was calculated for comparison between groups. X-ray films were reviewed to evaluate the quality of fracture reduction (Garden index) and healing, as well as the occurrence of internal fixation failure and femoral head necrosis. The patients of the three groups were successfully completed. Compared with the hollow screw group and the eccentric shaft screw group, the operation time and intraoperative blood loss of the support plate group significantly increased, the number of fluoroscopy reduced, and the quality of fracture reduction was better, the differences were significant ( P<0.05). The operation time, intraoperative blood loss, and the number of fluoroscopy of the hollow screw group were less than those of the eccentric shaft screw group, the differences were significant ( P<0.05). There was no significant difference in the length of hospital stay between groups ( P>0.05). All patients in the three groups were followed up 21-52 months, with an average follow-up time of 36.0 months, and there was no significant difference between groups ( P>0.05). The incisions of all patients healed by first intention. Imaging reexamination showed that there was no significant difference in the incidence of fracture nonunion between groups ( P>0.05). The fracture healing, partial weight-bearing, and full weight-bearing were significantly earlier in the eccentric shaft screw group and the support plate group than in the hollow screw group ( P<0.05). There was no significant difference in change value of Harris score, the incidence of postoperative deep venous thrombosis and femoral head necrosis between groups ( P>0.05); however, the incidence of internal fixation failure in the support plate group and the eccentric shaft screw group was significantly lower than that in the hollow screw group ( P<0.05). The incidence of postoperative lateral thigh irritation in the support plate group was significantly lower than that in the hollow screw group ( P<0.05); there was no significant difference between the eccentric shaft screw group and the other two groups ( P>0.05). The overall incidences of postoperative complications in the eccentric shaft screw group and the support plate group were significantly lower than that in the hollow screw group ( P<0.05). For young and middle-aged patients with Pauwels type Ⅲ femoral neck fracture, compared with simple hollow screw fixation in an inverted triangular shape, combined with medial support plate or eccentric shaft screw internal fixation can shorten the fracture healing time, reduce the incidences of postoperative complication, more conducive to early functional exercise of the affected limb; at the same time, the operation time and blood loss of combined eccentric shaft screw internal fixation are less than those of combined medial support plate internal fixation, so the hollow screw in an inverted triangular shape combined with eccentric shaft screw fixation may be a better choice.

Tension band high-strength suture combined with absorbable cannulated screws for treating transverse patellar fractures: finite element analysis and clinical study.

Objective: Few reports exist on the treatment of transverse patellar fractures (TPFs) using absorbable cannulated screws and high-strength sutures, and most screws and sutures lack good biomechanics and clinical trials. Therefore, this study aimed to demonstrate the biomechanical stability and clinical efficacy of tension-band high-strength sutures combined with absorbable cannulated screws (TBSAS) in treating TPFs (AO/OTA 34 C1). Methods: Finite element models of five internal fixation schemes were established: tension-band wire with K-wire (TBW), TBW with cerclage wire (TBWC), TBW with headless pressure screws (TBWHS), TBW with full-thread screws (TBWFS), and TBSAS. We comprehensively compared the biomechanical characteristics of the TBSAS treatment scheme during knee flexion and extension. Forty-one patients with TPFs in our hospital between January 2020 and August 2022 were retrospectively enrolled and divided into the TBSAS (n = 22) and TBWC (n = 19) groups. Clinical and follow-up outcomes, including operative time, visual analog scale (VAS) pain score, postoperative complications, Bostman score, and final knee range of motion, were compared between both groups. Results: Finite element analysis (FEA) showed that TBWHS and TBWFS achieved the minimum mean fracture interface relative displacement during knee flexion (45°, 0-500N bending load) and full extension (0°, 0-500N axial load). There was no significant difference between TBSAS (0.136mm) and TBWC (0.146mm) during knee flexion (500N); however, TBSAS displacement was smaller (0.075mm) during full extension (500N). Furthermore, the stress results for the internal fixation and the patella were generally lower when using TBSAS. Retrospective clinical studies showed that the TBSAS group had a shorter operative time, lower VAS pain score at 1 and 2months postoperatively, better Bostman knee function score at 3 and 9months postoperatively, and better final knee joint motion than the TBWC group (all p < 0.05). There were five cases (26.3%) of internal fixation stimulation complications in the TBWC group. Conclusion: TBSAS demonstrated excellent safety and effectiveness in treating TPFs. It is sufficient to meet the needs of TPF fixation and early functional exercise and effectively reduces metal internal fixation-induced complications and secondary surgery-induced trauma.

Rehabilitation care for pain in elderly knee replacement patients.

Total knee arthroplasty (TKA) is recognized as the most effective surgical intervention for relieving pain and improving joint mobility and deformity in patients with knee osteoarthritis and other synovial diseases. The application of accelerated postoperative rehabilitation (enhanced recovery after surgery) has demonstrated its efficacy in improving patient outcomes, and early postoperative joint function exercise has become a key prognostic factor in knee replacement. The unexpected appearance of limb pain and swelling hindered the patient's tendency for early mobilization, leading in prolonged hospitalization, delayed functional recovery and negative psychological responses. To investigate the impact of incorporating programmed pain nursing with collaborative nursing on elderly patients undergoing knee replacement surgery. A retrospective analysis was conducted on a cohort of 116 patients who underwent TKA at our hospital between July 2019 and July 2021. The patients were divided into two groups: A control group (n = 58) receiving programmatic nursing, and an observed group (n = 58) receiving programmed nursing combined with a collaborative nursing model. A pain management team consisting of attending physicians, head nurses, and responsible nurses was established. Outcome measures included visual analogue scale (VAS) scores, activities of daily living (ADL) scale scores, and functional scores. The ADL scores of patients in both groups exhibited a continuous increase. However, there was no statistically significant difference in the ADL scores between the two groups at 48 h and the 7th d post-surgery (P > 0.05). Upon reexamination at the 3rd mo, the observation group demonstrated higher ADL scores compared to the control group (67.48 ± 14.69 vs 59.40 ± 16.06, P < 0.05). The VAS scores of both groups significantly decreased, with no significant difference observed between the groups at each time point (P > 0.05). The functional status of patients in both groups exhibited a gradual increase prior to intervention and at the 1st, 2nd, and 3rd month following discharge (P < 0.05). There was no statistically significant difference in knee joint function scores between the two groups at the 1st month after discharge (47.52 vs 45.81, P > 0.05). However, the knee joint function scores of patients in the observation group were significantly higher than those in the control group at the 2nd (59.38 vs 53.19, P < 0.05) and 3rd month (71.92 vs 64.34, P < 0.05) following discharge. The utilization of programmed pain nursing in conjunction with collaborative nursing for out-of-hospital care of TKA patients has demonstrated favorable outcomes, encompassing pain reduction, enhanced prognosis, and improved nursing quality for patients.

Research progress on biomechanics for internal fixation in tibial plateau fracture

To review the biomechanical research progress of internal fixation of tibial plateau fracture in recent years and provide a reference for the selection of internal fixation in clinic. The literature related to the biomechanical research of internal fixation of tibial plateau fracture at home and abroad was extensively reviewed, and the biomechanical characteristics of the internal fixation mode and position as well as the biomechanical characteristics of different internal fixators, such as screws, plates, and intramedullary nails were summarized and analyzed. Tibial plateau fracture is one of the common types of knee fractures. The conventional surgical treatment for tibial plateau fracture is open or closed reduction and internal fixation, which requires anatomical reduction and strong fixation. Anatomical reduction can restore the normal shape of the knee joint; strong fixation provides good biomechanical stability, so that the patient can have early functional exercise, restore knee mobility as early as possible, and avoid knee stiffness. Different internal fixators have their own biomechanical strengths and characteristics. The screw fixation has the advantage of being minimally invasive, but the fixation strength is limited, and it is mostly applied to Schatzker typeⅠfracture. For Schatzker Ⅰ-Ⅳ fracture, unilateral plate fixation can be used; for Schatzker Ⅴand Ⅵ fracture, bilateral plates fixation can be used to provide stronger fixation strength and avoid the stress concentration. The intramedullary nails fixation has the advantages of less trauma and less influence on the blood flow of the fracture end, but the fixation strength of the medial and lateral plateau is limited; so it is more suitable for tibial plateau fracture that involves only the metaphysis. Choosing the most appropriate internal fixation according to the patient's condition is still a major difficulty in the surgical treatment of tibial plateau fractures. Each internal fixator has good fixation effect on tibial plateau fracture within the applicable range, and it is an important research direction to improve and innovate the existing internal fixator from various aspects, such as manufacturing process, material, and morphology.

Fixation of Terrible Triad Fracture in Young Adult through Anterior Approach – A Case Report

Introduction: The terrible triad of the elbow is defined as the combination of fractures of the radial head and ulnar coronoid process and dislocation of the elbow joint, and is often associated with collateral ligaments injuries. Objective: The objective is to report the clinical outcomes of an anterior surgical approach for coronoid fracture with plate fixation in the management of a case of terrible triad fracture with undisplaced radial head. Case Details: A 23 years old male presented with complaints of pain and swelling in right wrist and left elbow region since 1 day. He had a history of fall from height 1 day back with no known comorbidities or DNVD. Conclusion: Terrible triad fracture can be treated successfully with plate fixation through an anterior surgical approach in cases of undisplaced radial head with physiological range of motion at elbow which allows for accurate reduction and rigid internal fixation and early functional exercise, resulting in a favourable outcome.

Analysis of risk factors for axial symptoms after posterior cervical open-door laminoplasty

BackgroundLaminoplasty (LP), a procedure commonly used to treat cervical spondylotic myelopathy (CSM), often results in the development of axial symptoms (AS) postoperatively. This study aims to analyze the risk factors associated with the occurrence of AS after LP.MethodsWe collected and evaluated clinical data from 264 patients with CSM who underwent LP treatment at our institution from January 2018 to January 2022 through a single-center retrospective study. Of the patients, 153 were male and 111 were female, with an average age of 58.1 ± 6.7 years. All patients underwent C3-7 posterior laminoplasty. Based on the occurrence of postoperative axial symptoms, the patients were divided into an AS group and a non-AS group. General information, including age, gender, disease duration, Japanese Orthopaedic Association (JOA) score, postoperation early function training, and collar-wearing time, was recorded and compared between the two groups. Surgical-related data, such as operative segments, surgical time, intraoperative blood loss, intraoperative facet joint destruction, and destruction of the C7 spinous process muscle insertion, were also compared. Imaging data, including preoperative cervical curvature, cervical range of motion, preoperative encroachment rate of the anterior spinal canal, and angle of laminar opening, were collected. Univariate and multivariate logistic regression analyses were used to identify risk factors for the development of AS after LP, and receiver operator characteristic (ROC) curves were utilized to explore the optimal preoperative parameters.ResultsAll 264 patients successfully underwent surgery and were followed up for an average of 19.5 ± 6.8 months. At the 6-month follow-up, 117 patients were diagnosed with AS, resulting in an incidence rate of 40.2%. The multivariate logistic regression analysis identified that preoperative encroachment rate of anterior spinal canal (Pre-op ERASC), intraoperative facet joints destruction (Intra-op FJD), intraoperative open-door angle (Intra-op OA), destroy the C7 spinous process muscle insertion (Destroy C7 SPMI), postoperative loss of cervical curvature (Post-op LCC), and postoperative loss of cervical range of motion (Post-op LCROM) were independent risk factors for AS. Conversely, preoperative cervical curvature (Pre-op CC) and postoperation early function training (Post-op EFT) were protective factors against AS. According to the ROC curve, the cutoff values for preoperative anterior spinal canal occupation rate and preoperative cervical curvature were 28.5% and 16.5°, respectively. When the preoperative anterior spinal canal occupation rate was greater than 28.5% or the preoperative cervical curvature was less than 16.5°, AS was more likely to occur after surgery.ConclusionHigh preoperative anterior spinal canal occupation rate, facet joint damage during surgery, C7 spinous process muscle stop point damage, larger angle of laminar opening, and greater postoperative cervical curvature loss and cervical range of motion loss are associated with an increased risk of developing AS after cervical laminoplasty. Conversely, a larger preoperative cervical curvature and early postoperative functional exercises can help reduce the occurrence of AS.

Novel sternoclavicular hook plate for the treatment of posterior sternoclavicular dislocation: a retrospective study

BackgroundControversies regarding the optimal internal fixation method for posterior sternoclavicular dislocation (SCD) exist. Therefore, this study aimed to investigate the clinical efficacy of a new type of sternoclavicular hook plate for treating posterior SCD.MethodsEleven patients (eight men and three women) with posterior SCD who underwent treatment with the new sternoclavicular hook plate from June 2011 to January 2022 were retrospectively analyzed. The patients’ ages ranged from 33 to 71 years (54.91 ± 13.58 years). Operation time, blood loss, length of hospital stay, and postoperative complications were recorded. Postoperative joint reduction and healing were evaluated using radiography and computed tomography. The Constant–Murley and Rockwood sternoclavicular joint scores were used to evaluate the functional recovery of the affected limb 12 months after surgery.ResultsAll 11 patients were followed up for 12–24 months (18.00 ± 3.74 months). All incisions healed by first intention. The healing time ranged from 9 to 13 days (10.82 ± 1.54 days), and the joint healing time was 3–4 months (3.55 ± 0.52 months). The operation time was 45–75 min (59.55 ± 11.06 min), intraoperative blood loss was 22–58 mL (39.91 ± 11.07 mL), and the length of hospitalization was 6–14 days (9.91 ± 3.27 days). There were no complications such as infections, internal fixation failure, or nerve injury. The Constant–Murley score was 93.64 ± 9.01 at 12 months postoperatively. The Rockwood score was 13.36 ± 1.86, of which nine cases were excellent, one case was good, and one case was fair.ConclusionThe novel sternoclavicular hook plate is effective for the treatment of posterior SCD. This novel device can facilitate early joint functional exercises and good functional recovery.
