This study describes the long term clinical and patient reported outcomes following simple dislocation of the elbow. We identified all adult patients treated at our trauma centre for a simple dislocation of the elbow over 10 years. 140 patients were identified and 110 (79%) patients were reviewed at a mean of 88 (95% CI 80–96) months after injury. This included clinical examination, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, an Oxford Elbow questionnaire and a patient satisfaction questionnaire. Patients reported long-term residual deficits in range of movement. The mean DASH score was 6.5 (95% CI 4 to 9). The mean Oxford Elbow score was 43.5 (95% CI 42.2 to 44.8). The mean satisfaction score was 85.6 (95% CI 82.2 to 89). Sixty-two patients (56%) reported persistent subjective stiffness of the elbow. Nine (8%) reported subjective instability and 68 (62%) complained of continued pain. The DASH, Oxford Elbow and satisfaction scores all showed good correlation with absolute range of movement in the injured elbow. After multivariate analysis, a larger elbow flexion contracture and female gender were both independent predictors of worse DASH scores. Poorer Oxford Elbow scores and overall satisfaction ratings were predicted by reduced flexion-extension arc of movement. Patients report good long term functional outcomes after simple dislocations of the elbow. These are not entirely benign injuries. There is a high rate of residual pain and stiffness. Functional instability is less common and does not often limit activities

Purpose. To evaluate the long term results of the use of a postoperative autologous blood reinfusion system in total knee arthroplasty. Material and method. In a prospective study, 176 patients who underwent unilateral total knee replacement, during the period 2004–2008, were evaluated (study group or group A). In all these patients a reinfusion system of unwashed blood salvaged was applied, while supplementary homologous blood transfusion was performed when required. The admission of banked blood transfusion determined by haemoglobin value (<9mg/dL) and/or clinical signs (blood pressure, pulses, etc). The value of haemoglobin, haematocrite and platelets recorded preoperatively and the 1st, 5th and 15th day after operation. Results were compared with the material of our previous prospective randomized controlled study (control groups B and C), where in 60 patients, between the years 2002–2004, the effectiveness of postoperative autologous blood reinfusion had been proved. Results. 19 patients of group A required postoperatively 23 units of homologous blood (total study group requirements23 blood units or 0.13 units per patient) while in group B required 1.5 units/patient and in group C 0.3 units/patient. In the study group the total homologous blood requirements reduced by 91% compared with group B (patients without autotransfusion system applied) and by 47% compared with group C (patients with autotransfusion system applied). There was no statistically significant difference in the postoperative values of Hb and Ht between the groups. None of the patients developed any adverse reactions after reinfusion. The cost of blood management was reduced in study group by 76%. Conclusions. The use of an autotransfusion system postoperatively minimizes practically the demands for homologous banked blood transfusion in total knee arthroplasty

The Bernese Periacetabular Osteotomy (PAO) has become the established method for treating developmental dysplasia of the hip. In the 1990s, the surgical technique was modified to avoid postoperative cam impingement due to uncorrected head neck offset or pincer impingement due to acetabular retroversion after reorientation. The goal of the study was to compare the survivorship of two series of PAOs with and without the modifications of the surgical technique and to calculate predictive factors for a poor outcome. A retrospective, comparative study of two consecutive series of PAOs with a minimum follow-up of 10 years was carried out. Series A included 75 PAOs performed between 1984 and 1987 and represent the first cases of PAO. Series B included 90 hips that underwent PAO between 1997 and 2000. In this series, emphasis was put on an optimal acetabular version next to the correction of the lateral coverage. Additionally, a concomitant arthrotomy was performed in every hip to check impingement-free range of motion after reorientation and in 50 hips (56%) an additional offset correction was performed. Survivorship analyses according to Kaplan and Meier were carried out and the endpoint was defined as conversion to a total hip arthroplasty, progression of osteoarthritis, or a Merle d'Aubign score 14. Predictive factors for poor outcome were calculated using the Cox-regression analysis. The cumulative 10-year survivorship of Series A was significantly decreased (77%; 95%-confidence interval [CI] 72–82%) compared to Series B (86%; 95%-CI 82–89%, p=0.005). Hips with an aspherical head showed a significantly increased survivorship if a concomitant offset correction was performed intraoperatively (90% [95%-CI 86–94%] versus 77% [95%-CI 71–82%], p=0.003). Preoperative factors predicting poor outcome included a high age at surgery, a Merle d'Aubign score 14, a positive impingement test, a positive Trendelenburg sign, limp, an increased grade of osteoarthritis according to Tönnis, and (sub-) luxation of the femoral head (Severin > 3). In addition, predictive factors related to the three dimensional orientation of the acetabular fragment were identified. These included total, anterior, and posterior acetabular over-coverage or under-coverage, acetabular retroversion or excessive anteversion, a lateral center edge angle < 22 °, an acetabular index > 14 °, and no offset correction in aspherical femoral heads. A good long term result after PAO mainly depends on optimal three-dimensional orientation of the acetabulum and impingement-free range of motion with correction of an aspherical head neck junction if necessary

Introduction. When introducing new joint replacement designs, it is difficult to predict with any certainty the clinical performance of the new designs. Using roentgen stereophotogrammetric analysis (RSA) to evaluate the first two years of follow-up can serve as a predictor of late mechanical loosening for hip and knee prostheses. This prospectively randomized study was designed to evaluate the clinical performance of the Triathlon total knee system and compare the results between the two versions; posterior stabilized (PS) and cruciate retaining (CR). Methods. Sixty patients were consecutively randomized (two patients left the study prior to surgery) to receive either the Triathlon total knee PS (30 patients) or the Triathlon total knee CR (28 patients). All components were cemented. The study was approved by the Ethical Committee for Lund University. All patients met the inclusion criteria. There were no statistically significant differences between the demographics for PS and CR. RSA was set to be the principal evaluation parameter. Patient outcome was assessed by the KSS and KOOS questionnaires. Results. There were no statistically significant differences in rotation or translation around or along the three coordinal axes. Neither were there any differences in the maximal total point motion (MTPM) during the 2-year follow-up (p<0.05). There were no statistically significant differences between the clinical results of both groups when using the KSS and the KOOS scoring system (p<0.05). Discussion. There were no clinically significant differences in the RSA 2-year follow-up data, nor in the clinical scores of KSS and KOOS. The results of this study suggest that there is no major differences between the posterior stabilized system and the cruciate retaining system for the Triathlon total knee neither in clinical nor in predictable long term mechanical performance

INTRODUCTION. Cementless Total Hip Replacement surgery is a well established procedure for relative young patients with severe hip disease. Excellent long term clinical results have been published on the performance of the femoral component. With growing clinical experience, our concern focused on excessive wear of the Ultra High Molecular Weight Polyethylene (UHMWPE) ringloc liner of the Mallory Head cementless Total Hip Prosthesis. After its introduction in our clinic in 1997, this implant is still in use without any modification. We were concerned that due to premature liner wear, the performance of this implant would not be compliant with the international guideline on implant survival (NICE guidelines: at 10 year follow up, 90% of all implants should still be in situ). Our objective was to establish the amount of liner wear in our first 200 MH implants. METHODS. Our first 200 patients consecutively treated with Mallory Head prostheses were followed up to obtain a recent digital image. Follow up was complete for 181 (90.5%) of our 200 patients. Ten had died and nine were not able or willing to come for follow up. The mean duration of follow up was 8.3 years (range: 8–13). The 181 recent digital images were classified as either excessive wear or no excessive wear by two independent orthopedic surgeons. Next, liner wear was measured in the 2D frontal plane using PolyWare Pro/3D Digital Version Rev 5.1 software (Draftware Developers, Conway, USA). A threshold for excessive liner wear was set at 0.2mm/year, according to literature. RESULTS. Using software for measuring PE wear, 46.7% of all patients had excessive UHMWPE wear (> 0.2mm/yr). There was no relation between the amount of wear and BMI, gender, component size or the acetabular inclination angle. Thirteen patients (6.5%) were revised. Nine of these revisions were for excessive liner wear or aseptic loosening (4.5%). For now, our series of cementless Mallory Head prostheses is compliant with the NICE guideline on implant survival. However, with the measured amount of wear we expect to see a significant increase in the number of revisions for liner wear in the near future. DISCUSSION. Our clinical observation of premature UHMWPE wear proved correct. The measured amount of UHMWPE wear is consistent with the few other studies published on this subject. Although we present a retrospective study, limiting the strength of our results, we have included a large group of patients with acceptable loss to follow up. It is unclear if the observed wear will lead to a sharp increase in the number of revisions within the next few years. Possibly, future revisions will be complicated by loss of acetabular bone stock following the pathofysiological reaction to wear particles. Our results can probably be generalised for any district hospital

Background. The reported outcomes of unicompartmental knee replacement (UKR) for spontaneous osteonecrosis of the knee (SPONK) often derive from small series with an average followup of 5 years, enabling to generate meaningful conclusions. Therefore, we determined the long-term functional results and the 10-years survivorship of the implant in all patients with advanced SPONK of the medial tibio-femoral compartment treated with a unicompartmental knee arthroplasty at our institute. Methods. We retrospectively evaluated 84 consecutive patients with late stage SPONK. All patients received a pre-operative MRI to confirm the diagnosis, to exclude any metaphyseal involvement and to assess the absence of significative degenerative changes in the lateral and PF compartment. Mean age at surgery was 66 years and mean body mass index (BMI) was 28.9. In all cases, SPONK involved the medial compartment; in 77 cases the medial femoral condyle (MFC) was involved, while in 7 cases the pathology site was the medial tibial plateau (MTP). Radiological evaluation was conducted by 3 different radiologists and clinical evaluation according to KSS and WOMAC score was performed by 3 fellows from outside institutions, with no previous clinical contact with the patients, at a mean followup of 98 months. Results. We found a significant improvement in VAS score for residual pain self-assessment and maximum knee flexion (p<0.0001). The 10-year Kaplan-Meier survivorship with revision for any reason as endpoint was 89%. Mean results at final observation point for global KSS and WOMAC score were 87.1 (range 45–100; standard deviation 13.8) and 12 (range 0–44; standard deviation 10.3), respectively. No patient had significant radiographic signs of osteoarthritis progression in the lateral compartment or in the patello-femoral compartment at final evaluation. Conclusions. Our findings suggest that medial UKR performed for late stage SPONK of the medial tibio-femoral compartment in selected patients provides satisfactory long term clinical and radiographical results, with a 10-years Kaplan-Meier survivorship of the implant of 89%

Introduction

In total hip arthroplasty ceramic on ceramic bearing couples are used more and more frequently and on a wordwide basis. The main reason of this choice is reduction of wear debris and osteolysis. The tribological properties and the mechanical behaviour of the implanted ceramic must remain the same throughout the patient's life.

The aim of this study was to evaluate the resistance of Alumina Matrix Composite to environmental degradation.

Introduction

Displaced fractures in the sacrum are associated with other intra-pelvic organ injuries. There are some reports on short term outcome, however there is little knowledge about the long-term morbidity after these severe injuries.

The reconstruction of lower limb defects after oncological reconstructions is still a problem in limb salvage surgery. Large bony defects need to be treated with sound and durable reconstructions. During recent decades, the life expectancy of patients affected with cancer has improved considerably because of advances in chemotherapy, immunotherapy, hormonal treatment and radiotherapy. This improvement requires greater reliability in the reconstructive procedure in order to avoid mechanical failure during prolonged survival of the patient. The author experience with modular megaprosthesis by Link (megasystem C) allowed us to present a rapid, effective and functional solution.

From June 2001 to December 2007 225 patients have been operated with a megaprosthesis C for tumoral resection. The new megaprosthesis C by Link represents a wide-ranging system that can afford a large variety of reconstructions in the inferior limb, from very short replacement of 5 cm in proximal femur, to a total femur and proximal tibia replacement. Modularity is represented by 1 cm increase in length. The different options of cemented and not cemented stem may be used with intraoperative decision. In cemented stem a rough collar seals the osteotomy and prevents polyethylene debris from entering the femoral canal by inducing a scar tissue around the stem entrance (so-called purse-string effect). Moreover in patients with solitary lesions and very good prognosis an allograft-prosthesis composite can be performed with improved clinical results on walking and function. Of the 225 patients that underwent tumoral resection and reconstruction with a modular megaprosthesis approximately 43% (97 cases) were operated for metastatic disease. Among these cases 55 cases were proximal femoral recontructions, 39 cases were distal femoral reconstructions and 3 cases were proximal tibial reconstructions. All cases were performed with cemented stems. We experienced a 7% of postoperative infections, 2% of dislocations of proximal femoral prosthesis and 3% of mechanical failures. While infections and dislocation rates were in the average for this surgery, mechanical failures were relatively high. We should consider that in patients with relatively long resections and muscle deficiency the mechanical stress exerted on the prosthesis can explain this kind of mechanical failure. However the new design of morse tapers have annulled these problems

The present study sought to assess the clinical and radiological results and long-term joint impact of different techniques of lateral ankle ligament reconstruction.

Introduction

The implantation of DIAM in interspinous space is believed to act as facet joints and provides stability to operated segment by shifting instantaneous axis of rotation forward in lordotic disorders. In this retrospective study, the patients who underwent lumbar surgery with DIAM (Medtronic Sofamor, Danek) spacer implants were followed up with an aim to evaluate the clinical outcomes. To our knowledge, this is the largest series with longest follow up.

Aims

To analyse the influence of upper extremity trauma on the long-term outcome of polytraumatised patients.

Aims. To determine whether platelet-rich plasma (PRP) injection improves outcomes two years after acute Achilles tendon rupture. Methods. A randomized multicentre two-arm parallel-group, participant- and assessor-blinded superiority trial was undertaken. Recruitment commenced on 28 July 2015 and two-year follow-up was completed in 21 October 2019. Participants were 230 adults aged 18 years and over, with acute Achilles tendon rupture managed with non-surgical treatment from 19 UK hospitals. Exclusions were insertion or musculotendinous junction injuries, major leg injury or deformity, diabetes, platelet or haematological disorder, medication with systemic corticosteroids, anticoagulation therapy treatment, and other contraindicating conditions. Participants were randomized via a central online system 1:1 to PRP or placebo injection. The main outcome measure was Achilles Tendon Rupture Score (ATRS) at two years via postal questionnaire. Other outcomes were pain, recovery goal attainment, and quality of life. Analysis was by intention-to-treat. Results. A total of 230 participants were randomized, 114 to PRP and 116 to placebo. Two-year questionnaires were sent to 216 participants who completed a six-month questionnaire. Overall, 182/216 participants (84%) completed the two-year questionnaire. Participants were aged a mean of 46 years (SD 13.0) and 25% were female (57/230). The majority of participants received the allocated intervention (219/229, 96%). Mean ATRS scores at two years were 82.2 (SD 18.3) in the PRP group (n = 85) and 83.8 (SD 16.0) in the placebo group (n = 92). There was no evidence of a difference in the ATRS at two years (adjusted mean difference -0.752, 95% confidence interval -5.523 to 4.020; p = 0.757) or in other secondary outcomes, and there were no re-ruptures between 24 weeks and two years. Conclusion. PRP injection did not improve patient-reported function or quality of life two years after acute Achilles tendon rupture compared with placebo. The evidence from this study indicates that PRP offers no patient benefit in the longer term for patients with acute Achilles tendon rupture. Cite this article: Bone Joint J 2022;104-B(11):1256–1265

Lateral-entry wiring (LEW) for displaced supracondylar humeral fractures (SHFs) has been popularised internationally. BOAST guidance suggests either LEW or crossed wires; the latter has reported lower risk of loss of fracture reduction –we explore technical reasons why. We reviewed 8 years of displaced SHFs in two regional centres. Injuries were grouped using the Gartland Classification, with posterolateral or posteromedial displacement assessment for Gartland 3 injuries. We identified any loss of fracture reduction, and reviewed intra-operative imaging to identify learning points that may contribute to early rotational displacement (ERD). 345 SHFs were included, between 2012 and 2020. Gartland 2 (n=117) injuries had a 3.42% risk. ERD. Gartland 3 crossed wirings (n=114) had a 6.14% risk of ERD, with those moving all being posterolaterally displaced. Gartland 3, posterolaterally displaced LEW (n=56) had a 35.7% risk of ERD. Gartland 3, posteromedially displaced LEW (n=58) had a 22.4% risk of ERD. All injuries with ERD except 3 had identifiable learning points, the commonest being non-divergence of wires, or wires not passing through both fracture fragments. LEW requires divergent spread and bicolumnar fixation. Achieving a solid construct through this method appears more challenging than crossed wiring, with rates of ERD 3–5× higher. Low-volume surgeons should adhere to BOAST guidelines and choose a wiring construct that works best in their hands. They can also be reassured that should a loss of position occur, the risk of requirement for revision surgery is extremely low in our study (0.3%), and it is unlikely to affect long term outcomes

Limited long term data exists comparing operatively and non-operatively treated Achilles tendon ruptures. A previous randomised controlled trial comparing early outcomes showed a short term advantage for surgery, but there are no long term prospective randomised comparisons. Our aim was to determine whether surgery conferred long term benefits in terms of patient reported outcomes or re-rupture. 64 patients (80%) were followed up with postal questionnaires. Patients were asked to complete the Short Musculoskeletal Function Assessment (SMFA), Achilles Tendon Total Rupture Score (ATRS) and EQ-5D questionnaires, and to report re-ruptures. 32 patients were treated non-operatively and 32 operatively; 59 completed the SMFA and 64 the ATRS and EQ-5D assessments. There was no significant difference in SMFA score (median 1.09, IQR 4.89 in the cast group versus 2.17 and 7.07 in the operative group; p=0.347), ATRS (median 96, IQR 18 versus 93 and 15; p=0.509), EQ-5D Index (median 1.0, IQR 0.163 versus 1.0 and 0.257; p=0.327) and EQ-5D Visual Analogue Score (median score 85, IQR 15 versus 85 and 24; p=0.650). There were 2 re-ruptures in the operative group and 4 in the non-operative group (p=0.067). This is the first prospective, randomised, long term report comparing operative and non-operative management. At follow up between 13–17 years after injury, patients reported good function and health related quality of life. There was no significant difference in re-rupture rate between the treatment groups

Introduction. Trochleoplasty is an effective surgical procedure for patients with severe trochlear dysplasia and recurrent patella instability. Previous work has suggested patients demonstrate early improvements in knee function and quality of life. However, concerns regarding longer term outcomes due to the development of stiffness and patellofemoral osteoarthritis remain a concern for these patients. Our aim was to assess mid-term patient-reported outcome and quality of life measures for trochleoplasty performed at a single centre for severe trochlear dysplasia. Methods. Retrospective review of 28 knees (23 patients) having undergone trochleoplasty for severe trochlear dysplasia were reviewed. Due to the non-parametric nature of the data, median and interquartile range (IQR) were determined for pre-operative and mid-term follow-up scores. Statistically significant differences between groups were assessed using paired Wilcoxon-signed rank test with statistical significance set at p<0.05. Data were analysed using a statistical software package (IBM® SPSS® Statistics 26.0). Results. Median time from surgery to follow-up for all patients in the series was 5.3 years (IQR 3.9 – 7.0 years). Median pre-operative Kujala score improved from 57.0 (IQR 45 – 66) to 96.3 (IQR 83 -100). Median pre-operative IKDC score improved from 42.6 (IQR 35.9 – 51.3) to 92.6 (IQR 71.6 – 98.7). Median EQ-5D score also improved from 0.691 (IQR 0.414 – 0.727) to 1.000 (IQR 0.8178 – 1.000). Improvement in Kujala scores, IKDC scores and EQ-5D were all statistically significant with p<0.001 in all domains. Discussion. Our data suggests patients experience significant improvements in knee function and quality of life following trochleoplasty surgery for severe dysplasia. We demonstrate an absolute improvement in scores at a mean of 5.3 years follow-up of 39.3 points for Kujala, 50 for IKDC and 0.309 for EQ-5D. Minimal clinically important differences (MCID) have been reported to be in the region of 10 for the Kujala score, 8.8–15.6 for IKDC and 0.085 for EQ-5D. Our data shows improvements which far exceed the published MCID, suggesting trochleoplasty confers a large treatment effect and patients benefiting from sustained improvements in knee function and overall quality of life at mid-term follow-up. Conclusion. Following trochleoplasty for severe trochlear dysplasia, patient reported outcomes demonstrate continued improvements in knee function and quality of life at mid-term (5-year) follow-up. There is a large absolute treatment effect which likely impacts on both physical and psychological wellbeing for these patients. Continued surveillance of patient reported outcomes in this clinically complex cohort is indicated

There is a longstanding presumed association between obesity, complications, and revision surgery in primary knee arthroplasty. This has more recently been called into question, particularly in centres where a high volume of arthroplasty is performed. We investigated the correlation between Body Mass Index (BMI), mortality, and revision surgery. This was a cohort study of at least 10 years following primary knee arthroplasty from a single high volume arthroplasty unit. Mortality and revision rates were collected from all patients who underwent primary knee arthroplasty between 2009 and 2010. Kaplan Meier analysis was performed. There were 1161 female and 948 male patients with a mean age of 69 (21 to 97). All cause survivorship excluding mortality was 97.2% up to 13yrs with a minimum of 10 years. The revision rate in this series was 2.8% with no significant difference in revision rates after 10 year between patients with BMI above and below 40 (p=0.438). There was no significant difference in 10–year mortality between patients above and below a BMI of 40 (p=0.238). This study shows no significant difference in the long term survival of total knee replacement between patients with normal and high BMI. Careful consideration should be given before rationing surgery based on BMI alone

Cheilectomy is a recommended procedure for early stage osteoarthritis of the 1st metatarsophalangeal joint. Although improvement in symptoms has been reported in many studies, long term performance is not well understood. It is thought that significant numbers of patients require subsequent arthrodesis or arthroplasty. We report on a large cohort of patients receiving this procedure and on complications, and mid-term outcome. This is a retrospective study looking at all patients undergoing cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to record outcome measures including: postoperative wound infection, patient reported improvement in pain and incidence of further surgical interventions like revision cheilectomy, conversion to arthrodesis and arthroplasty. Osteoarthritis was staged radiographically using PACS (Hattrup and Johnson classification). A total of 240 feet in 220 patients (20 bilateral surgeries) were included with 164 females (75%) and 56 males (25%), the median age being 55 years (range 22–90 years). Radiological assessment showed 89 stage 1 arthritis (42%), 105 stage 2 (50%), 17 stage 3 (8%) and 9 patients were excluded due to unavailable radiographs. 5 patients (2%) had superficial wound infections. There were 16 further surgeries (7%); 12 arthrodesis (5%), 3 revision cheilectomy and 1 conversion to arthroplasty. 157 patients were found to be pain-free at the latest post-operative visit (77%), 48 reported minimal pain (23%), 15 patients were excluded due to incomplete data. Cheilectomy appears to effectively reduce pain with low complication rates. Rates of conversion to arthrodesis/arthroplasty are lower than in many reported studies

There is limited long term evidence to support instrumented fusion as an adjunct to decompression for foraminal stenosis in the presence of single level degenerative disc disease. We report the long term outcome of a prospective randomised controlled trial. Forty-four patients with single-level disc disease were randomly assigned to three groups (spinal decompression (Group 1), decompression and instrumented posterolateral fusion (Group 2), or decompression and instrumented posterolateral fusion plus transforaminal interbody fusion (Group 3). Spinal disability (Dallas, Roland Morris, and Lower Back Outcome Score [LBOS]), and quality of life (EuroQol (EQ) and short form (SF-) 36 questionnaires) were assessed before and at after surgery by independent researchers. At mean of 15 years follow up 33 (75%) patients were available for assessment. All groups observed a significant improvement in the EQ-5D at final follow up. Group 1 demonstrated significantly better functional outcome at final follow up according to the Dallas, Roland Morris, LBOS, and EQ-5D (3L and VAS) scores when compared to the other two groups (p<0.01). The SF-36 score demonstrated that group 1 had significantly better generic health scores compared to groups 2 and 3. Regression analysis was used to adjust for the differences in general health between the groups and demonstrated no significant difference between the groups in the spine specific scores: Dallas (p>0.15), Roland Morris (p>0.37), or the LBOS (p>0.32). Fusion in combination with decompression for the treatment of foraminal stenosis and single level degenerative disc disease offers no long term functional benefit over decompression in isolation

Backgrounds. Hip fractures have significant excess mortality, but it is unknown how long excess mortality persists. Our study was to explore the short and long term excess mortality after hip fractures, assess the impact of hip fracture on excess mortality and estimate the population attributable risk proportion (PARP) of risk factors for excess mortality. Methods. A total of 216 elderly with first time low trauma hip fracture admitted to NTUH were age and sex matched with 215 elder patients from Geriatric Department of the same hospital. All 63 covariates associated with mortality were analyzed using COX regression model. The survival status of these subjects was followed through National Death Registry for 60 months. Results. Hip fracture patients had an increased mortality in the first year after fractures compared with controls (Multivariable adjusted odds ratio {OR}: 2.4; 95% CI 1.05–5.4; PAR: 44.7%). At 60 months follow-up, the excess mortality of hip fracture remained high (OR: 2.7; 95% CI 1.3–5.5; PAR: 48.0%). Risk factors for short term mortality were hip fracture, betel nut use, comorbidities and MMSE< 19. Risk factors for long term mortality were hip fracture, ADL difficulty, smoking, coordination abnormality, T score < −2.19, BMI< 20 and the existence of comorbidities. Conclusions. Excess mortality after hip fracture lasts beyond 5 years. Excess mortality is attributable to hip fracture, which has higher PARP than other risk factors in both short and long term mortality
