Independent Walking Disability After Fragility Hip Fractures: A Prognostic Factors Analysis.

Introduction: Up to one-third of patients with fragility hip fractures are totally dependent in the year following the injury which leads to later morbidity and mortality. Understanding the related factors that affect patients' ambulation helps health care providers prepare for the treatment plans to improve their functional outcomes. This study aimed to evaluate the factors associated with independent walking disability in the early postoperative period after fragility hip fractures. Material and methods: This retrospective cohort study involved 394 patients with fragility hip fractures with either intertrochanteric, subtrochanteric, or femoral neck fractures from January 2018 to June 2023. The related factors including preoperative demographics, perioperative, and postoperative factors, were collected and analyzed. The endpoint was the independent walking disability of patients at 6 weeks after surgery. Results: 110 patients (27.9%) were disabled, whereas 284 patients (72.1%) could walk independently at postoperative 6 weeks. The multivariable risk ratio regression analysis showed that patients with age ≥80 years (RR 1.65; 95% CI 1.21-2.25; P = 0.001), pre-fracture walking with the gait aid (RR 2.03; 95% CI 1.53-2.69; P < 0.001), having ≥2 underlying comorbidities (RR 1.63; 95% CI 1.19-2.23; P = 0.002), preoperative hypoalbuminemia (RR 1.74; 95% CI 1.32-2.29; P < 0.001), and presence of the postoperative medical complication (RR 2.04; 95% CI 1.37-3.02; P < 0.001) were significantly associated with independent walking disability at the early postoperative period of 6 weeks. Conclusions: Post-hip fracture surgery patients with the presence of postoperative medical complication have the highest risk of independent walking disability. Health care providers should concentrate on high-risk patients, correct the modifiable factors, and minimize any postoperative complications to improve functional recovery and decrease morbidity related to non-ambulation after fragility hip fractures.

Additional intraoperative subpectoral plane block vs conventional pain control: A comparison of shoulder movement in patients with mastectomy.

PURPOSE: Shoulder pain is common among mastectomy patients, with limiting shoulder mobility and negatively affecting their quality of life. Pectoral nerve blocks (PECs) have demonstrated efficacy in providing postoperative analgesia. We hypothesized that these nerve blocks could improve shoulder movement in patients undergoing mastectomy. METHODS: This prospective, randomized, double-blind controlled trial enrolled female participants diagnosed with breast cancer and scheduled for mastectomy. Participants were randomly assigned to either the conventional analgesia group or the intervention group. In the intervention group, a PECs II block was applied prior to skin closure following a mastectomy. This study's primary outcome was the assessment of shoulder movement ratios in 5 different positions (forward elevation, external rotation, arm abduction, internal rotation, and cross-body adduction), which were recorded before surgery, at 24-h, 48-h, and 72-h intervals postoperatively, with follow-up at 1 month, 2 months, 3 months, and 6 months. RESULTS: A total of 59 participants were included in the final analysis. Patients who underwent mastectomy with PECs II block exhibited better shoulder movement in terms of external rotation and arm abduction from the early post-surgery up to 6 months postoperatively. Shoulder forward elevation also showed superior gains during the early postoperative period, with statistical significance observed after 1 month following the surgery. However, no significant differences were found between the two groups in terms of internal rotation and adduction movements of the shoulder. CONCLUSIONS: Compared to conventional analgesia, intraoperative pectoral nerve block under direct vision enhances shoulder mobility in forward elevation, external rotation, and arm abduction after mastectomy in breast cancer patients.

Quality of Life and Depression Status of Caregivers of Patients with Femoral Neck or Intertrochanteric Femoral Fractures during the First Year after Fracture Treatment.

OBJECTIVE: The burden placed on caregivers can negatively affect the functional recovery of patients with hip fractures. It is therefore essential to consider caregivers' well-being during the hip fracture care pathway. The aim of this study is to evaluate caregivers' quality of life and depression status during the first year after hip fracture treatment. METHODS: We prospectively enrolled the primary caregivers of patients with hip fractures admitted to the Faculty of Medicine Siriraj Hospital (Bangkok, Thailand) between April 2019 and January 2020. The quality of life of each caregiver was evaluated using the 36-Item Short Form Survey (SF-36), EuroQol 5-Dimensions 5-Levels (EQ-5D-5L), and EuroQol Visual Analog Scale (EQ-VAS). Their depression statuses were assessed using the Hamilton Rating Scale for Depression (HRSD). The outcome measures were collected during admission as baseline data and 3, 6 months, and 1 year after hip fracture treatment. The repeated measures analysis of variance was used to compare all outcome measures from baseline to each indicated time point. RESULTS: Fifty caregivers were included in the final analysis. The mean SF-36 physical and mental component summary scores decreased significantly from 56.6 to 54.9 (p = 0.012) and 52.7 to 50.4 (p = 0.043), respectively, during the first 3 months after treatment. The physical and mental component summary scores returned to baseline values 12 and 6 months posttreatment, respectively. Although the mean EQ-5D-5L and EQ-VAS scores significantly declined at 3 months, they returned to baseline values within 12 months. As for HRSD, 6%, 56%, 36%, and 6% of the caregivers reported mild depression symptoms at baseline and 3, 6, and 12 months posttreatment, respectively. CONCLUSIONS: The quality of life and depression status of hip fracture patients' caregivers worsen substantially in the first 3 months and return to baseline 1 year after hip fracture treatment. Specific attention and support should be given to caregivers, particularly during this difficult period. Caregivers should be regarded as "hidden patients" who need to be integrated into the hip fracture treatment pathway.

Additional Peripheral Nerve Block to Periarticular Injection Has No Benefit for Patients Undergoing TKA: A Factorial Propensity Score-Matched Analysis Comparing Four Multimodal Analgesic Techniques.

BACKGROUND: Controversy remains over what and how many analgesic techniques are required as the most effective multimodal pain regimen in total knee arthroplasty (TKA). This study aimed to evaluate the effect of additional analgesic methods combined with periarticular injection (PAI) analgesia for TKA. METHODS: Using retrospective cohort data, patients undergoing TKA with spinal anesthesia and PAI were divided into 4 groups. Group A (control) comprised 66 patients; group B (73 patients) had additional adductor canal block; group C (70 patients) obtained additional femoral nerve block, and group D (73 patients) received additional adductor canal block and intrathecal morphine. Propensity score matching was applied to compare visual analog scale (VAS) for pain intensity, cumulative morphine use (CMU), knee flexion angle, straight leg raise, length of hospital stay, and postoperative nausea and vomiting. RESULTS: There was no significant difference regarding VAS and morphine use, when either group B or C was compared with group A. Group D had significantly lower VAS than groups A, B, and C during the first 24 hours after surgery and required significantly less CMU than groups A and B. However, the pain score of group D increased afterward, with significantly longer length of hospital stay than groups A and B. There was no difference in straight leg raise among the groups. CONCLUSION: Additional peripheral nerve block to PAI provides no benefit for patients undergoing TKA. Adjuvant intrathecal morphine could significantly reduce the VAS and CMU in the acute postoperative period; however, rebound pain with prolonged hospital stays was observed.

Timing of periarticular injection has no effect on postoperative pain and functional recovery in simultaneous bilateral total knee arthroplasty: a prospective randomized, double-blinded trial.

BACKGROUND: Given no consensus on optimal timeframe of periarticular multimodal drug injection (PMDI) in knee osteoarthritis patients undergoing total knee arthroplasty (TKA), this study was aimed to compare the postoperative pain and the functional recovery in patients who underwent simultaneous bilateral TKA (SBTKA) and received PMDI at the different intraoperative time points. METHODS: This prospective, randomized, double-blinded controlled trial study included 48 patients who underwent SBTKA and received PMDI mixture, either before prosthetic implantation (late PMDI), or just after knee arthrotomy (early PMDI). Each subject's knees were randomly selected to different PMDI administration time points. The outcome parameters were postoperative pain assessed by using a visual analog scale (VAS), the maximal angle of knee flexion, and quadriceps function from day 1 to 6 weeks after surgery. RESULTS: Late PMDI revealed slightly higher VAS at 6 and 12 h after the operation than early PMDI administration. Afterward, the VAS tended to be lower in the late than early PMDI administration until the end of the study, but without statistical significance. The time difference between early and late PMDI had no effect on postoperative VAS, while older age resulted in significantly less pain. No statistical differences between the two groups in all other outcome parameters were observed. CONCLUSIONS: Postoperative pain reduction and functional recovery of SBTKA with early and late PMDI administration were not significantly different. The time interval of PMDI between knees did not confound the comparison of postoperative pain and functional recovery in SBTKA. TRIAL REGISTRATION: The protocol of this study was retrospectively registered in the Thai Clinical Trials Registry database No. TCTR20170617001 on 16 June 2017.

Validity and responsiveness of Barthel index for measuring functional recovery after hemiarthroplasty for femoral neck fracture.

INTRODUCTION: To investigate the validity of Barthel Index (BI) compared with de Morton Mobility Index (DEMMI), EuroQol-visual analog scale (EQ-VAS), 2-min walk test (2MWT), and timed get-up-and-go test (TUG), and to evaluate the responsiveness of all outcome measures for assessing functional recovery in older patients who underwent hemiarthroplasty after femoral neck fracture. MATERIAL AND METHOD: Eighty-one femoral neck fracture patients who were enrolled in a study evaluating functional recovery after bisphosphonate therapy during 2013 to 2015, and who had data available at both baseline and 12 months after surgery were included in this study. RESULTS: All scores improved significantly from baseline to the 1-year follow-up. BI had moderate to strong correlation with DEMMI, 2MWT, and TUG (r-value: 0.490-0.843), and mild to moderate correlation with EQ-VAS (r-value: 0.278-0.323). All outcome measurements had high effect estimates. The minimal clinically important difference (MCID) of BI at 12 months was 9.8 points. CONCLUSION: Since BI was shown to have good validity (moderate to strong correlation with DEMMI and performance-based tests, and mild to moderate correlation with EQ-VAS), BI can be used to accurately assess functional recovery in patients who undergo hemiarthroplasty after femoral neck fracture.

Appropriate Area for Operative Procedures Near Tibialis Anterior Tendon Insertion: A Cadaveric Study.

BACKGROUND: The tibialis anterior tendon has its insertion sites on both the medial and plantar surfaces of the medial cuneiform and the base of the first metatarsal. Operative procedures near those areas, especially at the first metatarsocuneiform joint, may disturb tendon insertions and cause irritation or functional impairment of the tendon. METHODS: Tibialis anterior tendons and their insertion sites were dissected and examined from 46 cadaveric feet (19 female and 27 male cadavers, aged between 33 and 86 years, with a mean of 68.5 ± 14.3 years). The greatest lengths and widths of the tendon attachments on the bony surface of the medial cuneiform and base of the first metatarsal, on both the medial and plantar surfaces, were measured and analyzed. The measurement reliability was evaluated by using the intraclass correlation coefficient. RESULTS: Most of the tibialis anterior tendon insertions were found to be longer at the medial cuneiform than at the base of the first metatarsal (mean, 8.3 and 5.4 mm; P < .001), but the widths were almost similar (mean, 11.0 and 10.4 mm; P = .079). When focusing on each bone, the widths of the tendon attachments on the medial and plantar surfaces of the medial cuneiform were equivalent (mean, 5.4 and 5.6 mm; P = .584). At the base of the first metatarsal, the tendon attachment on the plantar surface was found to be wider than on the medial surface (mean, 7.0 and 3.4 mm; P < .001). CONCLUSION: The widths of the tibialis anterior tendon insertions on the medial and plantar surfaces of the medial cuneiform were equal, as were the total widths of insertions on the medial cuneiform and on the base of the first metatarsal. However, the width of insertions on the medial surface of the first metatarsal was significantly smaller than on the plantar surface, and the total length of insertions at the medial cuneiform was longer than at the first metatarsal. CLINICAL RELEVANCE: This study provides information about characteristics of the tibialis anterior tendon insertions, particularly details of the dimensions on each surface of the bones. This knowledge enables surgeons to minimize the risk of irritation or tendon injuries during operations near the base of the first metatarsal and medial cuneiform area.

Effect of bisphosphonate initiation at week 2 versus week 12 on short-term functional recovery after femoral neck fracture: a randomized controlled trial.

The appropriate time to initiate bisphosphonate treatment after a fragility fracture has not yet been established. In this study, we found no significant differences in short-term functional recovery between femoral neck fracture patients who received bisphosphonate treatment at 2 versus 12 weeks after hemiarthroplasty. INTRODUCTION: Bisphosphonate is the mainstay therapy for prevention and treatment of osteoporosis. The aim of this study was to investigate the effect of bisphosphonate initiation on short-term functional recovery in femoral neck fracture patients at 2 versus 12 weeks after hemiarthroplasty. METHODS: One hundred patients were randomly allocated into two groups in a parallel group designed, randomized, controlled trial. Both groups received risedronate 35 mg/week at either 2 or 12 weeks after hemiarthroplasty. All patients received calcium and vitamin D supplementation. Functional recovery was assessed by de Morton Mobility Index, Barthel Index, EuroQol 5D, visual analog scale, 2-min walk test, and timed get-up-and-go test at 2 weeks, 3 months, and 1 year after surgery. RESULTS: At the 3-month follow-up, all functional outcome measures showed significant improvement in both groups. There were no statistically significant differences in any of the functional outcomes between groups at both the 3-month and 1-year follow-ups. Although patients who received bisphosphonate initiation at week 2 had lower serum calcium level at 3 months and more overall adverse events than patients in the week 12 group, no patients in either group discontinued their prescribed medications. CONCLUSIONS: While underpowered, the findings of this study suggest that there were no significant differences in short-term functional recovery or significant adverse events between the two bisphosphonate groups. Thus, the initiation of bisphosphonate therapy may be considered as early as 2 weeks after femoral neck fracture. It is important that low serum calcium and vitamin D status must be corrected with calcium and vitamin D supplementation prior to or at the time of bisphosphonate initiation. CLINICAL TRIAL REGISTRATION NUMBER: This study was registered in the database via the Protocol Registration and Results System (PRS) (NCT02148848).

Frequency and Characteristics of Extensor Hallucis Capsularis: A Cadaveric Study.

Background: Extensor hallucis capsularis is an accessory extensor tendon that is sporadically observed at the medial side of the extensor hallucis longus tendon. Knowledge regarding frequency of occurrence and size of the tendon may help surgeons decide whether to use this tendon or not when tendon graft is needed during foot surgery. Conclusion: Extensor hallucis capsularis tendon was found in the vast majority of cadavers evaluated in this study. Most originated from the extensor hallucis longus tendon and inserted into the first metatarsophalangeal joint capsule. Application of this tendon as a tendon graft should be carefully considered due to variations of the length and the narrow width which may limited strength of this tendon graft. Objective: To evaluate the frequency, size, origin, and insertion of the extensor hallucis capsularis tendon in cadaveric study subjects. Material and Method: Extensor hallucis capsularis tendon was examined via dissection of 55 cadaveric feet. Thirty-six male and 19 female cadavers were included, with an age range of 33 to 90 years (mean 67.3±14.0). One foot from each study subject was dissected and evaluated (29 left feet and 26 right feet). Demographic data (gender, age, and height) and outcome data (frequency, origin, insertion, length, and width of the tendon) were recorded. Tendon measurement reliability was evaluated by intraclass correlation coefficient. Results: Extensor hallucis capsularis tendon was found in 90.9% of cadaveric subjects. Mean tendon length and width was 11.3±4.0 cm and 1.6±0.6 mm, respectively. Most tendons branched from the extensor hallucis longus tendon and attached to the first metatarsophalangeal joint capsule. Conclusion: Extensor hallucis capsularis tendon was found in the vast majority of cadavers evaluated in this study. Most originated from the extensor hallucis longus tendon and inserted into the first metatarsophalangeal joint capsule. Application of this tendon as a tendon graft should be carefully considered due to variations of the length and the narrow width which may limited strength of this tendon graft.

Sensitivity and specificity of magnetic resonance imaging for knee injury and clinical application for the Naresuan University Hospital.

BACKGROUND: The accuracy of MRI evaluation for the traumatic knee injury may help the physician selecting the treatment options and informing patient about the prognosis. The purpose of the present study was to analyze the result of the MRI reported from a center in Phitsanulok which would be valuable for orthopaedic surgeons who practicing in the lower northern region of Thailand. MATERIAL AND METHOD: The 1.5 Tesla MRI of 51 injured knees that underwent subsequent arthroscopic knee surgery was independently reviewed by one from the group of radiologists. The sensitivity, specificity accuracy and negative predictive value of the MRI evaluation for menisci and cruciate ligament pathology compared to the arthroscopic finding is determined. RESULTS: There were 50 patients with the mean age of 36.7 year old (ranging from 18-75 years) and 30 were males and 20 were females. The sensitivity, specificity accuracy and negative predictive value (NPV) in detecting the complete tear of the ACL injury were 90.9%, 84.6%, 88.6% and 84.6%, respectively. There were 100%, 97.1%, 97.5% and 100%, respectively, for diagnosis of complete PCL tear. The MRI evaluation for definite medial meniscus tear revealed 100% in sensitivity, 52.6% in specificity, 64% in accuracy and 100% in NPV. For the lateral meniscus, it yielded 55.6%, 83.3%, 75.8% and 83.3%, respectively. Among the 22 patients who underwent the ACL reconstruction without the PCL or collateral ligament injury, there was 50% of associated meniscal injury with similar ratio between medial and lateral side. CONCLUSION: The MRI report from the center in Phitsanulok could be useful in detecting the cruciate ligament tear particularly with uncertain clinical examination. With a high negative predictive value, the MRI could be used as a negative diagnostic tool for the meniscal injury.
