RESUMEN
Background: Glenoid bone loss is a risk factor leading to the failure of arthroscopic Bankart repair. While 20-25% glenoid bone loss has long been considered the level to necessitate bony augmentation, recent studies indicate that 13.5% has a "subcritical" glenoid bone loss level, which is associated with decreased short- and medium-term functional scores. Few researchers worked on the long-term effect of "subcritical" or even less severe degrees of glenoid bone loss on redislocation rates and functional outcomes after arthroscopic Bankart repair. This study aimed to evaluate the effect of subcritical or less severe glenoid bone loss on redislocation rates and function after arthroscopic Bankart repair. Methods: A patient cohort who had undergone computed tomography (CT) of glenoid bone loss and arthroscopic Bankart repair over 15 years ago was reviewed. Western Ontario Shoulder Instability (WOSI) score, Single Assessment Numeric Evaluation (SANE) score, redislocation after operation, mechanism of recurrence, and revision details were reviewed. Results: Seventy-five patients were reassessed 17.6 ± 1.9 years following initial surgery. The age at enrolment was 26.8 ± 8.3 years. Twenty-two (29%) patients of the 75 patients had a redislocation on long-term follow-up, though this was not related to glenoid bone loss severity. The impaired functional score was found in patients with initial glenoid bone loss of 7% or more on long-term follow-up: WOSI (physical symptoms): 0.98 ± 2.00 vs 2.25 ± 4.01, p=0.04 and WOSI (total): 0.79 ± 1.43 vs 1.88 ± 3.56, p=0.04. Conclusions: At a mean of 17.5 years following arthroscopic Bankart repair, redislocation occurs in over a quarter of 75 patients, and they are not related to initial glenoid bone loss severity. Impaired functional outcome is apparent in patients with initial glenoid bone loss of >7%, though this impairment does not seem sufficiently severe to warrant an alternative treatment approach.
RESUMEN
BACKGROUND: The rate of geriatric hip fracture in Hong Kong is increasing steadily and associated mortality in fragility fracture is high. Moreover, fragility fracture patients increase the pressure on hospital bed demand. Hence, this study aims to develop a predictive model on the length of hospital stay (LOS) of geriatric fragility fracture patients using machine learning (ML) techniques. METHODS: In this study, we use the basic information, such as gender, age, residence type, etc., and medical parameters of patients, such as the modified functional ambulation classification score (MFAC), elderly mobility scale (EMS), modified Barthel index (MBI) etc, to predict whether the length of stay would exceed 21 days or not. RESULTS: Our results are promising despite the relatively small sample size of 8000 data. We develop various models with three approaches, namely (1) regularizing gradient boosting frameworks, (2) custom-built artificial neural network and (3) Google's Wide & Deep Learning technique. Our best results resulted from our Wide & Deep model with an accuracy of 0.79, with a precision of 0.73, with an area under the receiver operating characteristic curve (AUC-ROC) of 0.84. Feature importance analysis indicates (1) the type of hospital the patient is admitted to, (2) the mental state of the patient and (3) the length of stay at the acute hospital all have a relatively strong impact on the length of stay at palliative care. CONCLUSIONS: Applying ML techniques to improve the quality and efficiency in the healthcare sector is becoming popular in Hong Kong and around the globe, but there has not yet been research related to fragility fracture. The integration of machine learning may be useful for health-care professionals to better identify fragility fracture patients at risk of prolonged hospital stays. These findings underline the usefulness of machine learning techniques in optimizing resource allocation by identifying high risk individuals and providing appropriate management to improve treatment outcome.

OBJECTIVES: Dorsal central wrist pain, often a consequence of peri-scapholunate ligament injury, can result in a decline in functional performance. There is a scarcity of clinical data evaluating the effectiveness of conservative management on peri-scapholunate ligament injury. Conservative management includes education, immobilization with orthotic devices, scapholunate-stabilizing muscle strengthening, and proprioception training. The identification of the ligamento-muscular reflex and scapholunate-stabilizing muscles formed the rationale for a rehabilitation training program. We have devised an innovative standardized 16-week treatment program for patients with dorsal central wrist pain associated with acute peri-SL ligament injury. We hypothesized that the program can effectively reduce dorsal wrist pain and improve functional performance. MATERIALS AND METHODS: Recruited subjects underwent the 16-week home-based program, which included immobilization and rehabilitation exercises, to improve their wrist stability. Follow-up was arranged every 4 weeks for progress monitoring. The Short-Form 12 item questionnaire version 2, power grip, pinch grip, wrist range of motion, total performance score and total pain score when performing activities of daily living were used to evaluate the effectiveness of the program. An exercise adherence questionnaire was used to evaluate adherence to the home rehabilitation program. RESULTS: Twenty-three subjects (26 wrists) completed the program. Pain on visual analog scale improved by 5.1 cm and total pain score improved from 14.4/20 to 19.5/20. Total performance score reached 39/40, which indicated near-normal wrist function. Power grip and pinch grip increased by 22.3% and 17.8%, respectively. The physical component scale of the Short-Form 12 item questionnaire showed significant improvement, while the mental component scale did not. Overall adherence was fair. DISCUSSION: Conservative management, including immobilization and rehabilitation training, can provide significant clinical improvement in patients with dorsal central wrist pain associated with acute peri-scapholunate ligament injury. CONCLUSION: Standardized wrist rehabilitation can be taken as a reference treatment modality. It is an evidence-based non-invasive treatment option for clinicians and therapists.

Background: Total wrist replacement (TWR) is rarely done in the Asia-Pacific region. The aim of this study is to report the surgical outcomes and experience of TWR in patients with advanced arthritis. Methods: This is a retrospective review of all TWR patients in the Department of Orthopaedics and Traumatology, Prince of Wales Hospital, Hong Kong, which is a university tertiary centre, from January 2004 to March 2023. Recorded demographic parameters include gender, age upon surgery, pathology, types of implants and follow-up period. The surgical outcome parameters include range of motion, grip strength, wrist function assessment, radiological and clinical complications and any related secondary operations. Postoperative X-ray and clinical notes were reviewed. All wrist function assessments were performed by specialised occupational therapists according to protocol. Results: The study included a total of 12 wrists of 10 patients, all Chinese-Asian, with a mean age of 61.4 years at surgery. Larsen grade V arthritis constituted 50% and grade IV 16.7% of the patients, amongst which 33% had volar subluxation. The mean follow-up period was 97.4 months (21-205 months). The mean grip strength was 64.2% of the unaffected side. The mean postoperative Disabilities of Arm, Shoulder and Hand (DASH) score was 41.12% and patient-rated wrist/hand evaluation (PRWE) score 18.0. Complication incidence was 16.67% for loosening, 8.3% for metallosis and 8.3% for infection. One patient required conversion to total wrist arthrodesis due to metallosis. No patient suffered from dislocation, periprosthetic fracture and infection. Conclusions: TWR is an effective and safe alternative to total wrist arthrodesis with comparable outcomes. Our series outcomes are satisfactory and in line with literature. With meticulous soft tissue release and balancing, volar subluxation can also be corrected and may not be a contraindication. Level of Evidence: Level IV (Therapeutic).

Introduction: The COVID-19 pandemic has caused high mortality rates in hip fracture patients, but data for Asian patients are lacking. Whilst Cycle threshold (Ct) values and D-dimer have been reported as predictors of mortality in COVID-19 patients, their prognostic roles in those with concomitant hip fracture remain unknown. The objectives of this study were to i) assess the clinical outcomes of COVID-19 hip fractures patients in the Chinese population, ii) identify risk factors of mortality and complications, and iii) determine the prognostic roles of Ct values and D-dimer levels. Methodology: This cohort study was conducted during the 5th wave of the COVID-19 pandemic. Inclusion criteria were 1) hip fracture 2) â≥ â60 years old 3) low-energy trauma. Outcomes were 90-day all-cause mortality, complications, length of stay, discharge destination and mobility status. Logistic regression analysis was performed to identify risk factors for mortality and complications. Subgroup analysis was performed for patients with Ct â< â30 and Ct â> â30, comparing their outcomes of operations performed within 48 âh vs beyond 48 âh. Results: 159 hip fracture patients were included, 42 patients were COVID-19 positive. COVID-19 group had significantly higher 90-day mortality rates (21.4% vs 9.4%), complication rates (45.2% vs 28.2%) and longer length of stay (17.06 vs 10.84 nights). COVID-19 was an independent risk factor for mortality and complications. Amongst the COVID-19 group, risk factors for poor outcomes were advanced age, steroids use, conservative treatment and American Society of Anaesthesiologists (ASA) score ≥ 3. Conservative treatment was associated with higher mortality (OR â= â16.00; p â= â0.025) in COVID-19 hip fracture patients. There was no significant difference between Ct values â< â30 and >30 regarding mortality and complication rate. D-dimer and timing to operation did not affect outcomes. Conclusions: Patients with concomitant COVID-19 and hip fracture are at high risk of mortality and complications. Ct values and D-dimer levels have no prognostic roles for hip fracture outcomes. Early operative treatment is recommended as soon as patients are medically fit.
RESUMEN
OBJECTIVES: Triangular fibrocartilage complex (TFCC) injury is a common cause of ulnar-sided wrist pain. However, treatment protocols vary across clinical settings and a standardized treatment protocol is needed to improve quality of care. We devised a rehabilitation regime which comprised both orthoses and exercises. We hypothesized that the program can effectively reduce pain and improve functional performance. MATERIALS AND METHODS: Thirty-two subjects participated in the 5-phase rehabilitation program. Progress was monitored every 3 weeks. Outcome measures comprised numeric pain rating scale (NPRS), activities of daily living (ADL) pain score, wrist range of motion (ROM), ADL performance score, patient-rated wrist evaluation (PRWE), power grip and distal radioulnar joint (DRUJ) instability grade. RESULTS: NPRS decreased from 5.3/10 to 0.5/10 while the ADL pain score improved from 10/20 to 19.1/20. ROM in flexion/extension and supination/pronation improved by 35%. Functional performance on ADL performance score and PRWE improved from 21/40 to 38/40 and 49.5/100 to 14.6/100, respectively. Power grip increased by 59.5%, and DRUJ stability improved. DISCUSSION: The combination of orthoses and progressive strengthening and proprioception training was effective in re-establishing DRUJ stability, and improving wrist strength and functional performance. CONCLUSIONS: This study provided insight for the development of a rehabilitation protocol for patients with TFCC injury.

BACKGROUND: Wound complication, skin blister formation in particular, causes devastating consequences after total knee arthroplasty (TKA). Negative Pressure Wound Therapy (NPWT) tries to improve wound management leading to decrease length of hospital stay and better clinical outcomes. Low body mass index (BMI) could play a part in wound recovery management although lacking evidence. This study compared length of hospital stay and clinical outcomes between NPWT and Conventional groups, and factors affected and how BMI affected. METHODS: This was a retrospective clinical record review of 255 (160 NPWT and 95 Conventional) patients between 2018 and 2022. Patient demographics including body mass index (BMI), surgical details (unilateral or bilateral), length of hospital stay, clinical outcomes including skin blisters occurrence, and major wound complications were investigated. RESULTS: Mean age of patients at surgery was 69.95 (66.3% were female). Patients treated with NPWT stayed significantly longer in the hospital after joint replacement (5.18 days vs. 4.55 days; p = 0.01). Significantly fewer patients treated with NPWT found to have blisters (No blisters: 95.0% vs. 87.4%; p = 0.05). In patients with BMI < 30, percentage of patients requiring dressing change was significantly lower when treated with NPWT than conventional (0.8% vs. 33.3%). CONCLUSION: Percentage of blisters occurrence in patients who underwent joint replacement surgery is significantly lower using NPWT. Patients using NPWT stayed significantly longer in the hospital after surgery because significant proportion received bilateral surgery. NPWT patients with BMI < 30 were significantly less likely to change wound dressing.

INTRODUCTION: Popularity of joint replacement surgery due to ever aging population surges the demand for a proper national joint registry. Our Chinese University of Hong Kong - Prince of Wales Hospital (CUHK-PWH) joint registry has passed the 30th year. The aims of this study are 1) summarize our territory-wide joint registry which has passed the 30th year since establishment and 2) compare our statistics with other major joint registries. METHODS: Part 1 was to review the CUHK-PWH registry. Demographic characteristics of our patients who underwent knee and hip replacements had been summarized. Part 2 was a series of comparisons with registries from Sweden, UK, Australia and New Zealand. RESULTS: CUHK-PWH registry captured 2889 primary total knee replacements (TKR) (110 (3.81%) revision) and 879 primary total hip replacements (THR) (107 (12.17%) revision). Median Surgery time of TKR was shorter than THR. Clinical outcome scores were much improved after surgery in both. Uncemented of hybrid in TKR were most popular in Australia (33.4%) and 40% in Sweden and UK. More than half of TKR and THR patients showed the highest percentage with ASA grade 2. New Zealand reflected the best cumulative percentage survival 20 years after surgery of 92.2%, 76.0%, 84.2% survivorship 20 years after TKR, unicompartmental knee replacement (UKR) and Hip. CONCLUSION: A worldwide accepted patient-reported outcome measure (PROM) is recommended to develop to make comparisons among registries and studies feasible. Completeness of registry data is important and useful to improve surgical performance through data comparisons from different regions. Funding from government on sustaining registries is reflected. Registries from Asian countries have yet to be grown and reported.

Acute lateral ankle sprains are common amongst athletes, and screening is essential in preventing these long-term sequelae. Self-reported questionnaires, such as the Cumberland Ankle Instability Tool (CAIT), may help identify individuals with chronic ankle instability. To date, a Cantonese-Chinese version of the CAIT does not exist. A cross-cultural adaptation and validation of the CAIT were carried out: 46 individuals who were native in Cantonese completed the Cantonese-Chinese version of the CAIT and Chinese Foot and Ankle Outcome Score. For the test-retest analysis, the intraclass correlation coefficient was 0.874. Internal consistency showed a Cronbach's É value of 0.726. Construct validity against the FAOS was fair but statistically significant with a Spearman's correlation coefficient of 0.353, 0.460, 0.303, 0.369 and 0.493 for the categories of symptoms, pain, daily function, sports function, and quality of life, respectively. A cutoff score of 20.5 was determined to differentiate healthy individuals from those with chronic ankle instability for this study population. The original English CAIT was successfully translated, cross-culturally adapted and validated into Cantonese-Chinese.

BACKGROUND: The development of total knee arthroplasty (TKA) for knee osteoarthritis (OA) has a good reputation for its effectiveness in reducing joint pain and improving range of motion. We aimed to review our early results using the image-free robotic-assisted technology in knee arthroplasty. METHODS: A total of 71 patients suffering from end-stage OA knee receiving TKA operated by robotic-assisted surgery between the years 2018 and mid-2021 were recruited. Clinical and radiological outcomes were compared with age and sex-matched control group (conventional TKA). RESULTS: The radiological outcome showed significantly more postoperative lower limb alignment outliers in conventional side than robotic-assisted sides. Postoperative knee scores were similar among both groups. Robotic-assisted TKA required a longer implantation time but a shorter hospital stay. CONCLUSION: Robotic-assisted TKA achieved a lower rate of mechanical axis Outlier in the coronal and sagittal plane with a shorter hospital stay. Yet both methods achieve a similar functional outcome.

Tibial intercondylar fracture with anterior cruciate ligament avulsion is a unique but rare complication of bicruciate-retaining total knee arthroplasty. Here, we describe an even rarer condition that the tibial intercondylar fracture involved bicruciate ligament and partial patellar tendon avulsion fracture resulting in significant clinical instability in a 70-year-old woman, a combination not yet reported in the literature. Dual-energy computed tomography helped characterize the fracture. During revision surgery, the bicruciate retaining total knee arthroplasty was revised to posterior-stabilized total knee arthroplasty and the patellar tendon was repaired with a suture anchor. She recovered well progressively, and at 6 months, she could walk with the use of an assisted walking device.
RESUMEN
The incidence of geriatric hip fractures continues to rise in our aging population and has become a major public health concern globally. The primary outcome of this study was to determine whether Age-adjusted Charlson Comorbidity Index (ACCI) is associated with increased fracture-related complications in neck of femur fractures treated by internal fixation. This was a cohort study between January 2014 to June 2018. All patients ≥ 50 years old with an acute neck of femur fracture after low-energy trauma fixed with cannulated hip screws were included and followed-up for 1 year at a tertiary centre. Primary outcome was to determine whether ACCI was associated with increased fracture-related complications. Secondary outcomes were revision rate, mortality, and function after surgery. Further analysis were performed within a "younger" group (age 50-65) and "elder" group (age > 65), as displaced fractures (Garden Type III/IV) were in "younger" group. 233 hip fractures (68 males; 165 females) with a mean age of 73.04 ± 12.89 were included in the study. Surgical outcomes showed that the complication rate of hip screw fixation for all patients was 21.5% (50 patients) at 1 year. ACCI was significantly higher in all patients with complications (p = 0.000). Analysis within "younger" (p = 0.000) and "elder" groups (p = 0.006) both showed significance. Stepwise logistic regression modelling showed ACCI had positive correlation with complications with ACCI = 6 (OR 4.27, p = 0.02). R2 values were comparatively better after controlled by Garden Type III/IV at ACCI = 4 (OR 6.42 (1.70, 24.25), p = 0.01). The authors recommend that for patients with a Garden Type I/II and ACCI ≥ 6 or a Garden Type III/IV and ACCI ≥ 4, a direct arthroplasty surgery should be considered.

BACKGROUND: A patient-reported outcome (PRO) tool which reflects the outcomes of patients underwent total knee arthroplasty (TKA) are important to be "ceiling effect free" which commonly used PRO tools face. Forgotten joint score-12 (FJS-12) has been proved to reduce or even free from ceiling effect. FJS-12 has been translated to different languages. The objectives of this study are to validate FJS-12 in Traditional Chinese-Hong Kong language and look for the goodness of FJS-12 still exist in this language adapted FJS-12 version. METHODS: FJS-12 was administered to 75 patients whose majority was obese underwent TKA between September 2019 and March 2020. Patients completed 3 sets of questionnaires (FJS-12, Oxford Knee Score (OKS), and Numeric Rating Scale (NRS)) twice, 2 weeks apart. Reliability, internal consistency, responsiveness, test-retest agreement and discriminant validity were evaluated. RESULTS: Reliability of FJS-12 showed moderate to excellent internal consistency (Cronbach's α = 0.870). Test-retest reliability of FJS-12 was good (ICC = 0.769). Bland-Altman plot showed good test-retest agreement. Construct validity in terms of correlations between FJS-12 and OKS, and FJS-12 and NRS were moderate at baseline (Pearson's coefficient r = 0.598) and good at follow-up (r = 0.879). Smallest detectable change (Responsiveness) was higher than MIC. Floor effect was none observed, and ceiling effect was low. Discriminant validity was found to have no significance. BMI (obesity) did not affect FJS-12 outcomes. CONCLUSIONS: The Traditional Chinese-Hong Kong version of FJS-12 showed good test-retest reliability, validity, responsiveness, BMI non-specific, with no floor and low ceiling effects for patients who underwent TKA. Sub-culture differences in individual PRO tools should be considered in certain ethnicities and languages.

Aims: With increasing life expectancy and ageing population, more octogenarians would benefit from total knee arthroplasty (TKA). The aim of this study is to evaluate the survivorship of TKA in octogenarian and their long-term outcomes. Methods: This was a retrospective review of 67 patients aged above 80 years who had primary TKA performed between 2005 and 2013 at a single centre. A sex-matched younger cohort of 67 primary TKAs during the same time-period was recruited for control. Five and 10-year survival was calculated. Pre- and peri-operative factors were collected and compared. Post-operative range of motion, Knee Society Score (KSS) and Function Score (KFS) were collected and compared. Rate of revision, infection, aseptic loosening and mortality was collected. Results: The mean follow-up period was 10.39 ± 2.29 years. The 5- and 10-year survival of octogenarian group was 85.1% and 54.6%, respectively. Pre- and peri-operative factors between the octogenarian and control groups were comparable (p > 0.05). Both groups showed improvement in range of motion, KSS and KFS post-operatively. Rate of revision, aseptic loosening and deep infection was 0% in octogenarian and 1.5% in control group. Conclusion: TKA can be performed in patients with age above 80 years old with comparable post-op knee range, complication rate and long-term functional score. Advanced age should not be a limiting factor for TKA.

BACKGROUND: Osteoarthritis (OA) of the knee is one of the most common chronic degenerative joint diseases, and a multi-disciplinary approach to educating patients with OA knee are effective in symptoms management. Tai Chi exercise is a novel approach to relieving knee OA symptoms. Combining both educational program and Tai Chi has not yet been explored. METHODS: Multi-disciplinary education program included a total of 4-week 2-h weekly talks delivered by different health professionals with live demonstrations. This was then followed by a 1-h Tai Chi class (Baduanjin). Results from IPAQ (Physical activity level), WOMAC (evaluate knee OA conditions), and SF-36v2 (quality of life) were collected at the first class of education program, 3 and 6 months after the end of Tai Chi class. CSQ-8 (program effectiveness) was administered on the last day of Tai Chi class. RESULTS: One hundred and twelve patients joined the program. The overall attendance was over 90% with close-to-zero dropout rate. Satisfaction scored high in 85% of patients. WOMAC pain scores (p = 0.04) and SF-36v2 emotional role (p = 0.02) were statistically decreasing (improving) at 6 months after the program. SF-36v2 physical role and mental health tended to improve with time. CONCLUSIONS: Combining both multidisciplinary education program program and Tai Chi exercise for knee OA patients was proven feasible. This program received high satisfaction, high attendance and very low dropout rates without any adverse event. Patients' pain and emotion were significantly improved. A large-scale randomized trial introducing a control group is recommended. TRIAL REGISTRATION: Registry: ClinicalTrials.gov Registration number: NCT04204213 Date of registration: 18/12/2019 (Retrospectively registered).

Fracture liaison services (FLS) have been implemented worldwide, but we present one of the first reported experiences in China. Only 1 out of 226 patients had a secondary fracture within 1 year. This serves as a platform to improving solutions and decreasing imminent fractures for future use nationwide in China. INTRODUCTION: Fracture liaison services (FLS) have been implemented worldwide but we present one of the first reported experiences in China. Vertebral fragility fracture is one of the earliest fracture to occur. The objective of this study was to implement a dedicated fracture service to decrease imminent fractures for future use nationwide in China. METHODS: Patients 50 years or older with a recent vertebral compression fracture were recruited. All patients were offered investigation with DXA scan and blood taking. Treatment was provided with calcium and vitamin D supplements and denosumab injections. The primary outcome was the imminent fracture rate or the re-fracture rate occurring within 2 years of the initial one. Secondary outcomes were bone mineral density (BMD), treatment initiation, adherence to drug, compliance to follow-up, falls, mortality, pain, quality of life, pain-related disability with Roland-Morris Disability Questionnaire (RMDQ), and Oswestry Disability Index (ODI). RESULTS: Two hundred twenty-six patients (n = 226) were analyzed. 0.4% (n = 1) had an imminent fracture within 2 years. 11.1% (n = 25) had a fall within 2 years, in which 1 resulted in a major osteoporotic fracture. 7.1% died (n = 16) within the 2-year time period. 97.8% (n = 221) underwent BMD investigation with an initial DXA scan. One hundred percent (n = 226) had treatment initiation and were prescribed with Denosumab injections. 89.8% (n = 203) were compliant and showed complete adherence to drug therapy over the 2 years. Pain, quality of life, and disability were significantly improved. CONCLUSION: This is the first reported fracture liaison service for vertebral fracture patients reported in China. Future FLS should incorporate muscle and sarcopenic assessments as a routine, and also research on novel interventions in this area would significantly improve patient outcomes.

Osteoporosis is a systemic skeletal disease characterized by low bone mass and bone structural deterioration that may result in fragility fractures. Use of bone imaging modalities to accurately predict fragility fractures is always an important issue, yet the current gold standard of dual-energy X-ray absorptiometry (DXA) for diagnosis of osteoporosis cannot fully satisfy this purpose. The latest high-resolution peripheral quantitative computed tomography (HR-pQCT) is a three-dimensional (3D) imaging device to measure not only volumetric bone density, but also the bone microarchitecture in a noninvasive manner that may provide a better fracture prediction power. This systematic review and meta-analysis was designed to investigate which HR-pQCT parameters at the distal radius and/or distal tibia could best predict fragility fractures. A systematic literature search was conducted in Embase, PubMed, and Web of Science with relevant keywords by two independent reviewers. Original clinical studies using HR-pQCT to predict fragility fractures with available full text in English were included. Information was extracted from the included studies for further review. In total, 25 articles were included for the systematic review, and 16 articles for meta-analysis. HR-pQCT was shown to significantly predict incident fractures and/or major osteoporotic fractures (MOFs). Of all the HR-pQCT parameters, our meta-analysis revealed that cortical volumetric bone mineral density (Ct.vBMD), trabecular thickness (Tb.Th), and stiffness were better predictors. Meanwhile, HR-pQCT parameters indicated better performance in predicting MOFs than incident fractures. Between the two standard measurement sites of HR-pQCT, the non-weight-bearing distal radius was a more preferable site than distal tibia for fracture prediction. Furthermore, most of the included studies were white-based, whereas very few studies were from Asia or South America. These regions should build up their densitometric databases and conduct related prediction studies. It is expected that HR-pQCT can be used widely for the diagnosis of osteoporosis and prediction of future fragility fractures. © 2021 The Authors.

The objective of this study was to investigate the prognostic factors predicting the ambulation recovery of fragility hip fracture patients. 2286 fragility hip fracture patients were collected from the Fragility Fracture Registry in Hong Kong. Predictive factors of ambulation deterioration including age, gender, pre-operation American Society of Anesthesiologists grade, pre-fracture mobility, delay to surgery, length of stay, fracture type, type of surgery, discharge destination and complications were identified. Patients with outdoor unassisted and outdoor with aids ambulatory function before fracture had 3- and 1.5-times increased risk of mobility deterioration, respectively (Odds Ratio (OR) = 2.556 and 1.480, 95% Confidence Interval (CI) 2.101-3.111 and 1.246-1.757, both p < 0.001). Patients living in old age homes had almost 1.4 times increased risk of deterioration when compared to those that lived in their homes (OR = 1.363, 95% CI 1.147-1.619, p < 0.001). The risk also increased for every 10 years of age (OR = 1.831, 95% CI 1.607-2.086, p < 0.001). Patients in the higher risk ASA group shows a decreased risk of ambulation deterioration compared to those in lower risk ASA group (OR = 0.831, 95% CI 0.698-0.988, p = 0.038). Patients who suffered from complications after surgery did not increased risk of mobility decline at 1-year post-surgery. Delayed surgery over 48 h, delayed discharge (> 14 days), early discharge (less than 6 days), and length of stay also did not increased risk of mobility decline. Male patients performed worse in terms of their mobility function after surgery compared to female patients (OR = 1.195, 95% CI 1.070-1.335, p = 0.002). This study identified that better premorbid good function, discharge to old age homes especially newly institutionalized patients, increased age, lower ASA score, and male patients, correlate with mobility deterioration at 1-year post-surgery. With the aging population and development of FLS, prompt identification of at-risk patients should be performed for prevention of deterioration.

BACKGROUND/PURPOSE OF THE STUDY: Changes in health-related quality of life (HRQOL) of AIS patients coming across both bracing and surgery have not yet reported. These patients received two major clinical interventions and their HRQOL might be different from previous articles. The aim of this study is to evaluate the changes of HRQOL of a specific group of AIS patients who experienced both bracing and surgery. METHODS: One hundred and twenty-eight patients requiring surgery with prior bracing treatment were identified from the electronic record. SRS-22 questionnaire was completed at 7 time points crossing both interventions (namely "Before", "Bracing ≤ 1 year", "Bracing > 1 year", "Pre-op", "Post-op", "Post-op ≤ 1 year, and "Post-op 1-2 years"). RESULTS: SRS-22 "Function", "Pain" and "Self-image" scores were decreased from "Before" to "Bracing ≤ 1 year" when started bracing and raised at "Bracing > 1 year". The 3 scores were dropped from "Bracing > 1 year" to "Pre-op", particularly on "Self-image". "Function" and "Pain" were significantly dropped from "Pre-op" to "Post-op" and kept raising until "Post-op 1-2 years". "Self-image" was improving after "Pre-op". "Mental" was relatively stable along the timeline. CONCLUSION: This study described the changes in HRQOL of a specific group of AIS patients. Scores were dropped after the two major clinical interventions and recovered afterwards. Medical professionals were able to plan and provide appropriate supports on the expected changes in HRQOL, especially on function, pain and mental.
RESUMEN
BACKGROUND: Osteonecrosis of the femoral head (ONFH) is a debilitating condition. Vascularized iliac bone graft (VIBG) is a joint-preserving surgery to improve blood supply to the avascular portion of the femoral head which may delay secondary osteoarthritis and total hip arthroplasty (THA). However, whether VIBG will affect the subsequent THA survivorship and outcomes are still uncertain. METHODS: Implant survivorship and clinical outcomes were compared between 27 patients who had undergone prior VIBG and 242 patients who had only undergone THA for ONFH. Baseline characteristics and the postoperative Harris Hip Score (HHS) were also recorded and compared between the two groups. Implant survivorship was determined using Kaplan-Meier survival analysis. RESULTS: The overall implant survival for all patients who had a primary diagnosis of ONFH and eventually underwent THA was 92.9%. There was no significant difference in the implant survivorship between the group who directly received THA (survivorship of 93%) and the group which failed VIBG and was subsequently converted to THA (survivorship of 91.9%) (p = 0.71). In addition, higher THA revision rates were associated with smokers and drinkers. CONCLUSIONS: VIBG may be a reasonable option as a "buy-time" procedure for ONFH. Even if conversion to THA is eventually required, patients may be reassured that the overall survivorship and clinical outcomes may not be compromised. Patients are recommended to give up smoking and binge drinking prior to THA to increase implant survival rate.
