Aims

The aim of this study was to investigate if there are differences in outcome between sliding hip screws (SHSs) and intramedullary nails (IMNs) with regard to fracture stability.

Aims. Patient decision aids have previously demonstrated an improvement in the quality of the informed consent process. This study assessed the effectiveness of detailed written patient information, compared to standard verbal consent, in improving postoperative recall in adult orthopaedic trauma patients. Methods. This randomized controlled feasibility trial was conducted at two teaching hospitals within the South Eastern Sydney Local Health District. Adult patients (age ≥ 18 years) pending orthopaedic trauma surgery between March 2021 and September 2021 were recruited and randomized to detailed or standard methods of informed consent using a random sequence concealed in sealed, opaque envelopes. The detailed group received procedure-specific written information in addition to the standard verbal consent. The primary outcome was total recall, using a seven-point interview-administered recall questionnaire at 72 hours postoperatively. Points were awarded if the participant correctly recalled details of potential complications (maximum three points), implants used (maximum three points), and postoperative instructions (maximum one point). Secondary outcomes included the anxiety subscale of the Hospital and Anxiety Depression Scale (HADS-A) and visual analogue scale (VAS) for pain collected at 24 hours preoperatively and 72 hours postoperatively. Additionally, the Patient Satisfaction Questionnaire Short Form (PSQ-18) measured satisfaction at 72 hours postoperatively. Results. A total of 60 patients were randomized, 32 to the standard group and 28 to the detailed group. Patients in the detailed group had significantly higher total recall score compared to the standard group (mean difference 1.29 points (95% confidence interval (CI) 0.51 to 2.08); p = 0.002). There were no differences in HADS-A (mean difference 0.39 (95% CI -2.11 to 2.88); p = 0.757), VAS pain (mean difference 5.71 (95% CI -22.25 to 11.11); p = 0.499), or PSQ-18 (mean difference 0.499; 95% CI -1.6 to 3.42; p = 0.392). Conclusion. Detailed written tools are useful in improving postoperative recall in adult orthopaedic trauma patients. Cite this article: Bone Jt Open 2023;4(2):104–109

Aims. No randomized comparative study has compared the extensile lateral approach (ELA) and sinus tarsi approach (STA) for Sanders type 2 calcaneal fractures. This randomized comparative study was conducted to confirm whether the STA was prone to fewer wound complications than the ELA. Methods. Between August 2013 and August 2018, 64 patients with Sanders type 2 calcaneus fractures were randomly assigned to receive surgical treatment by the ELA (32 patients) and STA (32 patients). The primary outcome was development of wound complications. The secondary outcomes were postoperative complications, pain scored of a visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, 36-item Short Form health survey, operative duration, subtalar joint range of motion (ROM), Böhler’s angle and calcaneal width, and posterior facet reduction. Results. Although four patients (12.5%) in the ELA groups and none in the STA group experienced complications, the difference was not statistically significant (p = 0.113). VAS and AOFAS score were significantly better in the STA group than in the ELA group at six months (p = 0.017 and p = 0.021), but not at 12 months (p = 0.096 and p = 0.200) after surgery. The operation time was significantly shorter in the STA group than in the ELA group (p < 0.001). The subtalar joint ROM was significantly better in the STA group (p = 0.015). Assessment of the amount of postoperative reduction compared with the uninjured limb showed significant restoration of calcaneal width in the ELA group compared with that in the STA group (p < 0.001). Conclusion. The ELA group showed higher frequency of wound complications than the STA group for Sanders type 2 calcaneal fractures even though this was not statistically significant.

Aims. The aim of this study was to compare the incidence of anterior knee pain after antegrade tibial nailing using suprapatellar and infrapatellar surgical approaches. Patients and Methods. A total of 95 patients with a tibial fracture requiring an intramedullary nail were randomized to treatment using a supra- or infrapatellar approach. Anterior knee pain was assessed at four and six months, and one year postoperatively, using the Aberdeen Weightbearing Test – Knee (AWT-K) score and a visual analogue scale (VAS) score for pain. The AWT-K is an objective patient-reported outcome measure that uses weight transmitted through the knee when kneeling as a surrogate for anterior knee pain. Results. A total of 53 patients were randomized to a suprapatellar approach and 42 to an infrapatellar approach. AWT-K results showed a greater mean proportion of weight transmitted through the injured leg compared with the uninjured leg when kneeling in the suprapatellar group compared with the infrapatellar group at all timepoints at all follow-up visits. This reached significance at four months for all timepoints except 30 seconds. It also reached significance at six months at 0 seconds, and for one year at 60 seconds. Conclusion. The suprapatellar surgical approach for antegrade tibial nailing is associated with less anterior knee pain postoperatively compared with the infrapatellar approach.

Aims. Tibial plateau fractures are serious injuries about the knee that have the potential to affect patients’ long-term function. To our knowledge, this is the first study to use patient-reported outcomes (PROs) with a musculoskeletal focus to assess the long-term outcome, as compared to a short-term outcome baseline, of tibial plateau fractures treated using modern techniques. Methods. In total, 102 patients who sustained a displaced tibial plateau fracture and underwent operative repair by one of three orthopaedic traumatologists at a large, academic medical centre and had a minimum of five-year follow-up were identified. Breakdown of patients by Schatzker classification is as follows: two (1.9%) Schatzker I, 54 (50.9%) Schatzker II, two (1.9%) Schatzker III, 13 (12.3%) Schatzker IV, nine (8.5%) Schatzker V, and 26 (24.5%) Schatzker VI. Follow-up data obtained included: Visual Analogue Scale (VAS) or Numeric Rating Scale (NRS) pain scores, Short Musculoskeletal Functional Assessment (SMFA), and knee range of movement (ROM). Data at latest follow-up were then compared to 12-month data using a paired t-test. Results. Patient-reported functional outcomes as assessed by overall SMFA were statistically significantly improved at five years (p < 0.001) compared with one-year data from the same patients. Patients additionally reported an improvement in the Standardized Mobility Index (p < 0.001), Standardized Emotional Index (p < 0.001), as well as improvement in Standardized Bothersome Index (p = 0.003) between the first year and latest follow-up. Patient-reported pain and knee ROM were similar at five years to their one-year follow-up. In total, 15 of the patients had undergone subsequent orthopaedic surgery for their knees at the time of most recent follow-up. Of note, only one patient had undergone knee arthroplasty following plateau fixation related to post-traumatic osteoarthritis (OA). Conclusion. Knee pain following tibial plateau fracture stabilizes at one year. However, PROs continue to improve beyond one year following tibial plateau fracture, at least in a statistical sense, if not also clinically. Patients displayed statistical improvement across nearly all SMFA index scores at their minimum five-year follow-up compared with their one-year follow-up.

Aims. The aim of this study was to evaluate the clinical and radiological outcomes of locking plate fixation, with and without an associated fibular strut allograft, for the treatment of displaced proximal humeral fractures in elderly osteoporotic patients. Patients and Methods. We undertook a retrospective comparison of two methods of fixation, using a locking plate without an associated fibular strut allograft (LP group) and with a fibular allograft (FA group) for the treatment of these fractures. The outcome was assessed for 52 patients in the LP group and 45 in the FA group, with a mean age of 74.3 years (52 to 89), at a mean follow-up of 14.2 months (12 to 19). The clinical results were evaluated using a visual analogue scale (VAS) score for pain, the Constant score, the American Shoulder and Elbow Surgeons (ASES) score, and the range of movement. Radiological results were evaluated using the neck-shaft angle (NSA) and humeral head height (HHH). Results. The mean forward elevation in the LP and FA groups was 125.3° (. sd. 21.4) and 148.9° (. sd. 19.8), respectively (p = 0.042), while other clinical factors showed no statistically significant differences between the groups. The changes in NSA and HHH immediately after the operation and at final follow-up were significantly better in the FA group than in the LP group (p = 0.015 and p = 0.021, respectively). Conclusion. For comminuted proximal humeral fractures in osteoporotic patients, locking plate fixation with a fibular strut allograft shows satisfactory short-term results with respect to humeral head support and maintenance of reduction, and may reduce the incidence of complications associated with fixation using a locking plate alone.

Aims. The Edinburgh Trauma Triage Clinic (TTC) streamlines outpatient care through consultant-led ‘virtual’ triage of referrals and the direct discharge of minor fractures from the Emergency Department. We compared the patient outcomes for simple fractures of the radial head, little finger metacarpal, and fifth metatarsal before and after the implementation of the TTC. Patients and Methods. A total of 628 patients who had sustained these injuries over a one-year period were identified. There were 337 patients in the pre-TTC group and 289 in the post-TTC group. The Disabilities of the Arm, Shoulder and Hand Score (QuickDASH) or Foot and Ankle Disability Index (FADI), EuroQol-5D (EQ-5D), visual analogue scale (VAS) pain score, satisfaction rates, and return to work/sport were assessed six months post-injury. The development of late complications was excluded by an electronic record evaluation at three years post-injury. A cost analysis was performed. Results. Outcomes were as good or better post-TTC, compared with pre-TTC scores. At three years, the pre-TTC group required a total of 496 fracture clinic appointments compared with 61 in the post-TTC group. Mean cost per patient was nearly fourfold less after the commencement of the TTC. Conclusion. Management of minor fractures through the Edinburgh TTC results in clinical outcomes that are comparable with the previous system of routine face-to-face consultation. Outpatient workload for these injures was reduced by 88%. Cite this article: Bone Joint J 2018;100-B:959–65

BACKGROUND. Osteoporosis with subsequent osteoporotic vertebral compression fractures is an increasingly important disease due not only to its significant economic impact but also to the increasing age of our population. Pain reduction and stabilization are of primary importance with osteoporotic vertebral compression fractures. OBJECTIVE. To compare the efficacy and safety of balloon kyphoplasty and vertebroplasty for the treatment of vertebral compression fractures. MATERIALS & METHODS. From January 2004 to December 2009, 142 patients (32 males and 110 females), from 54 to 84 years old (mean age 67.4) were treated for 185 osteoporotic vertebral fractures of the thoracic or lumbar spine (level of fracture at Th5 or lower), with back pain for more than 8 weeks, and a visual analogue scale (VAS) score of 5 or more. Twenty-two patients (29 fractures) were lost at follow-up period and excluded. Patients were randomly allocated to percutaneous kyphoplasty (64%) or vertebroplasty (36%). All fractures were analyzed for improvement in sagittal alignment (Cobb angle, kyphotic angle, sagittal index, vertebral height). The patients were evaluated using the visual analog scale (VAS) and the Oswestry Disability Score. Radiographs were performed postoperatively, and at 1, 3, 6, and 12 months. RESULTS. The score according to pain, the patient's ability to ambulate independently and without difficulty, and the need for medications improved significantly (P < 0.001) after kyphoplasty or vertebroplasty. No significant difference could be found between both groups for the mean VAS and ODI preoperative and postoperative. Vertebral body height and kyphotic wedge angle of the T-L spine were also improved (p < 0.001); although kyphosis correction seems to be improved better in kyphoplasty than vertebroplasty. The rate of leakage was 12% for kyphoplasty and 32% for vertebroplasty; nevertheless most of the leakage was clinically asymptomatic and the rate of serious problems remained low (pulmonary embolism 0.01% kyphoplasty vs 0.6% vertebroplasty). New fractures in the next 6 months at the adjacent vertebrae were observed ∼ 15% in both groups. More PMMA was used in the kyphoplasty group than in the vertebroplasty group (5.5 +/− 0.8 vs. 4.1 +/− 0.5 mL, p < 0.001). Operation time was longer in balloon kyphoplasty compared to vertebroplasty (mean time 20±5min/vertebral fracture in group B vs 30±5min in group A). CONCLUSION. Both balloon kyphoplasty and vertebroplasty provided a safe and effective treatment for pain and disability in patients with vertebral compression fractures due to trauma or osteoporosis. Balloon kyphoplasty led to an ongoing reduction of fractured vertebrae and was followed by a lower rate of cement leakage

Only a few randomised, controlled studies have compared different non-operative methods of treatment of mid-shaft fractures of the clavicle. . In this prospective, randomised controlled study of 60 participants (mean age 31.6 years; 15 to 75) we compared the broad arm sling with the figure of eight bandage for the treatment of mid-shaft clavicle fractures. Our outcome measures were pain, Constant and American Shoulder and Elbow Surgeons scores and radiological union. The mean visual analogue scale (VAS) pain score on the first day after treatment was significantly higher (VAS 1 6.8; 4 to 9) in the figure of eight bandage group than the broad arm sling group (VAS 1 5.6; 3 to 8, p = 0.034). A mean shortening of 9 mm (3 to 17) was measured in the figure of eight bandage group, versus 7.5 mm (0 to 24) in the broad arm sling group (p = 0.30). The application of the figure of eight bandage is more difficult than of the broad arm sling, and patients experience more pain during the first day when treated with this option. We suggest the broad arm sling is preferable because of the reduction of early pain and ease of application. Cite this article: Bone Joint J 2015;97-B:1562–5

Anterior knee pain (AKP) is the commonest complication of total knee arthroplasty (TKA). This study aims to assess whether sagittal femoral component position is an independent predictor of AKP after cruciate retaining single radius TKA without primary patellofemoral resurfacing. From a prospective cohort of 297 consecutive TKAs, 73 (25%) patients reported AKP and 89 (30%) reported no pain at 10 years. Patients were assessed pre-operatively and at 1, 5 and 10 years using the short form 12 and Oxford Knee Score (OKS). Variables assessed included demographic data, indication, reoperation, patella resurfacing, and radiographic criteria. Patients with AKP (mean age 67.0 (38–82), 48 (66%) female) had mean Visual Analogue Scale (VAS) Pain scores of 34.3 (range 5–100). VAS scores were 0 in patients with no pain (mean age 66.5 (41–82), 60 (67%) female). Femoral component flexion (FCF), anterior femoral offset ratio, and medial proximal tibial angle all differed significantly between patients with AKP and no pain (p<0.001), p=0.007, p=0.009, respectively). All PROMs were worse in the AKP group at 10 years (p<0.05). OKSs were worse from 1 year (p<0.05). Multivariate analysis confirmed FCF and Insall ratio <0.8 as independent predictors of AKP (R. 2. = 0.263). Extension of ≥0.5° predicted AKP with 87% sensitivity. AKP affects 25% of patients following single radius cruciate retaining TKA, resulting in inferior patient-reported outcome measures at 10 years. Sagittal plane positioning and alignment of the femoral component are important determinants of long-term AKP with femoral component extension being a major risk factor

Achilles tendinopathy is characterised by chronic degeneration of the Achilles tendon, usually secondary to injury or overuse. Extracorporeal shockwave treatment (ESWT) is of potential benefit in refractory cases where conservative management with analgesia, physiotherapy and corticosteroid injection have been unsuccessful. Patients with refractory Achilles tendinopathy enrolled between October 2010 and October 2011 received three sessions of ESWT over three weeks. Patients completed visual analogue scale (VAS) scores for pain at rest and on activity and the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire pre-treatment. These outcome measures and a six-point Likert satisfaction scale were reassessed at six and 16 weeks post treatment. 51 patients completed follow up. Mean age was 56 (34–80) years and mean length of symptoms 34 (4–252) months. Significant improvement (p<0.05) in VAS scores (rest and activity) and VISA-A scores was observed between baseline and 16 weeks. Mean Likert score was 3 (somewhat improved) at 16 weeks. Patients suffering Achilles tendinopathy for longer than 25 months had significantly less improvement than those affected for a shorter period. This study suggests that ESWT improves subjective and objective outcomes in patients with refractory Achilles tendinopathy

Aim. The present study was designed to evaluate the implantation of alginate beads containing human mature allogenic chondrocytes for the treatment of symptomatic cartilage defects in the knee. Methods. A biodegradable, alginate-based biocompatible scaffold containing human mature allogenic chondrocytes was used for the treatment of chondral and osteochondral lesions in the knee. Twenty-one patients were clinically prospectively evaluated with use of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and a Visual Analogue Scale (VAS) for pain preoperatively and at 3, 6, 9, 12, 24 and 36 months of follow-up. Results. A statistically significant clinical improvement became apparent after 6 months and patients continued to improve during the 36 months of follow-up. Adverse reactions to the alginate/fibrin matrix seeded with the allogenic cartilage cells were not observed. Two of the procedures failed. One of the patients had loosening of the periosteal flap, which was attributed to a failure of the surgical procedure. The other failure case was the result of the poor quality and quantity of the repair tissue itself. Discussion. The results of this pilot study show that the alginate-based scaffold containing human mature allogenic chondrocytes is feasible for the treatment of symptomatic cartilage defects in the knee. The described technique provides clinical outcomes equal to those of other cartilage repair techniques

We have devised a new scoring system using visual analogue scales (VAS) to determine the functional outcome in 15 patients with 20 displaced intra-articular calcaneal fractures, confirmed by CT. The average follow-up was 19 months. A VAS was completed separately by the patient, the surgeon and an independent assessor. It showed satisfactory agreement between observers and strong correlations with a General Health Survey (SF36), a pain scale (McGill Pain Questionnaire) and a disease-specific, historical scale for calcaneal fractures (the Rowe score)

Plantar fasciitis is thought to be a self limiting condition best treated by conservative measures, but despite this many patients have a prolonged duration of symptoms and for some surgery may be indicated. Partial plantar fascial release is reported to have a short term success rate of up 80%, but anecdotally this was not thought to represent local experience. An audit of long term patient reported outcomes following surgery was performed. A total of 26 patients (29 feet) were identified retrospectively and case notes were reviewed for each patient. Patients were contacted by letter and invited to complete two validated patient reported outcome score questionnaires (foot and ankle visual analogue scale (VAS) and MOXFQ). The average age of the patients was 42.4(range 28–61) for males and 46.2 (range 33–60) for female patients, with a female:male ratio of 2.7:1. Preoperative treatments included orthotics (29), steroid injections (23), physiotherapy (21) and cast immobilisation (11). The average duration of treatment prior to surgical intervention was 3.1 years (range 1–5). All patients were reviewed post operatively and discharged from follow up at an average of 31 weeks, at which time 38% remained symptomatic. We conclude that the results from open partial plantar fascial release are poor and it is a technique of dubious clinical value

Introduction. Biomechanical studies have shown that a long, centrally placed screw is favourable in scaphoid fracture fixation. A volar percutaneous transtrapezial approach was developed to facilitate central screw placement. The purpose of this study was to evaluate radiographic changes at the ST-joint at long term follow up in patients where this approach was used. Method. Results were graded with use of the visual analogue scale (VAS) and modified Mayo wrist score. Radiographs of both hands, comprising an anteroposterior, lateral and 45 degrees pronated oblique view were obtained. Degenerative changes at the ST-joint were staged according to the modified Eaton & Glickel classification. Results. 34 patients with an average age of 34 years were followed at a mean of 6.1 years (4–9). Union was obtained in all at an average time of 6.4 weeks (6–10). There were no significant differences in VAS score and ROM, between the operated and nonoperated side (p>0.05). The mean Mayo wrist score was 93 (80–100). Three patients showed stage 2 osteoarthritis of the ST-joint. In 2 patients, stage 2 osteoarthritis was found in both the injured and uninjured side. One patient had asymptomatic stage 2 osteoarthritic changes at the injured side. Discussion. The advantages of the volar percutaneous transtrapezial approach include central screw placement, without the need for manipulation of the wrist. From the present study it can be concluded that the volar percutaneous transtrapezial approach to fix scaphoid fractures does not lead to significant radiographic degenerative changes in the ST joint at a follow-up of more than 6 years

In medical research and among health-care providers there has been a marked shift to a focus on patient-reported outcome (PRO) and how it is measured and analysed. In this study from the Swedish Hip Arthroplasty Register we present the development and results of a nationwide, prospective, observational follow-up programme including patient-reported outcome measures (PROMs). The programme started in 2002 and has gradually expanded to include all units performing THA surgery in Sweden. The self-administered PROM protocol comprises the EQ-5D instrument, the Charnley categorization and visual analogue scales (VAS) for pain and satisfaction. These current analyses include 34 960 THAs with complete pre- and one-year postoperative questionnaires. Patients eligible for THA generally report low health-related quality of life (HRQoL) and suffer from pain. One year post-operatively the mean EQ-5D index increased from 0.41 to 0.78 (p<0.001) which is above the level of an age- and gender-matched population. Pain was reduced from mean VAS 62 to 14 (p<0.001). Females, younger patients and those with Charnley category C reported lower EQ-5D index pre-operatively than males, older patients and Charnley A or B, respectively, did (all p<0.001). In a multivariable regression analysis Charnley category C, male gender and higher age were associated with less improvement in HRQoL (p<0,001). Patients' response rates to the Registry was 86% pre-operatively and 90% one year post-operatively. Nationwide implementation of a PROM programme requires a structured organization and effective IT solutions. The continuous collection of PROs permits local and national improvement work and allows for further health-economic evaluation

Aims

The aims of this study were to report the outcomes of patients with a complex fracture of the lower limb in the five years after they took part in the Wound Healing in Surgery for Trauma (WHIST) trial.

Introduction. Chronic pain is one of the adverse outcomes in surgery for degenerative lumbar pathology (DLP). Postoperative complications as DVT, and chronic pain in pathologies as thoracotomy or breast cancer have been associated with poor control of postoperative pain. Study design. Prospective study of patients undergoing surgery for DLP. Purpose. To evaluate the relationship of postoperative pain with final outcomes in terms of chronic pain and quality of life. Outcome measures. Visual analogue scales (VAS) to assess lumbar and leg pain, Short Form-36v2 (SF-36), Oswestry Disability Index (ODI) and Core Outcome Measures Index (COMI). Method. 263 patients with a mean age of 54.0 years (22–86 y) were reviewed and 131 patients were women (49.8%). Pain, quality of life and disability of patients were assessed in the immediate preoperative and 2 years after surgery. Epidemiological data collected were age, sex, educational level, employment status, diagnosis, treatment, and comorbidity (ASA). An external nurse evaluated postoperative pain four times every day and we selected the worst value of day. The reference value of postoperative pain was the VAS of third day when patient starts standing and PCA is removed. To compare means we used t-Student and Pearson's coefficient or Spearman's test was used to assess the correlation, and, finally, linear regression study (ANOVA) was performed with variables that showed statistically significant correlation. SPSS 15.0 statistical package. Results. The mean value of VAS on 3rd day (VAS-3) was 2.86 ± 2.2. Postoperative pain showed a moderately positive correlation with final pain, measured by Bodily Pain (r=0.310, p <0.05) and final VAS (r=0.318, p <0.001), and moderately negative with the Physical Component Scale of the SF36 (r=−0.269, p <0.05). No significant correlations existed with the other instruments. Preoperative pain, sex and MSC-SF36 was correlated with postoperative pain (r=0.262 p <0.05; r=− 0.261 p <0.003, r=− 0.306 p <0.001). According to linear regression studies each point in the VAS-3 will be an increase of 0.522 points in the final VAS (p <0.01). Conclusions. Postoperative pain has moderate but statistically significant influence in the final lumbar pain perception, assessed by VAS and Bodily Pain. Postoperative pain has an inverse relationship to the physical component of SF-36. However, postoperative pain is not correlated with disability measured by ODI or COMI

Introduction. An important number of factors affecting the outcome of surgical treatment have been identified, and these factors can affect the patient's selection for lumbar surgery. Study Design. Retrospective study with data collected prospectively on patients undergoing surgery for degenerative lumbar pathology (DLP). Purpose. Identification and evaluation of epidemiological factors that influence the quality of life improvement, disability and chronic pain. Outcome measures. Visual Analogue Scale (VAS) to assess pain in lower back and extremities, Short Form-36v2 (SF-36), Oswestry Disability Index (ODI) and Core Outcome Measures Index (COMI). Method. 263 patients were included in our study, with a mean age of 54.0 years (22–86 years). 131 patients were women (49.8%). Questionnaires were completed in the preoperative visit and 2 years after surgery. Epidemiological data collected were age, sex, educational level, employment status, diagnosis, treatment, and comorbidity measure by ASA. The most frequent diagnostics were degenerative discal disease (36,5%) and lumbar stenosis (30,4%) and a main surgical treatment was TLIF (31,9 %). To compare means we used t-Student and Pearson's coefficient or Spearman's test was used to assess the correlation, and, finally, linear regression study (ANOVA) was performed with variables that showed statistically significant correlation. SPSS 15.0 statistical package. Results. Sex and employment status was correlated with the improvement of COMI (r=− 0.257, p <0.05, r=0.272, p <0.05). Employment status was correlated with in ODI (r=0.249, p <0.05) and the degree of improvement physical component of SF-36 (PCS, r=− 0.254, p <0.05). Linear regression showed statistically significant influence of the age (r=0.334, p <0.05) and employment status (r=14.146, p <0.01) on ODI. COMI is statistically influenced by sex (r=− 0.869, p <0.01), age (r=0.027, p <0.05) and employment status (r=0.830, p <0.05). PCS is statistically influenced by the employment status (r=− 8.568, p <0.01), age (r=− 0.228, p <0.05) and sex (r=5.525, p <0.05). Conclusions. According to the present study we observed that the perception of change in the quality of life and disability after surgery of the lumbar spine is independent of the initial pathology, the type of surgery and previous pain and disability; but sex, age and employment status have an important influence

BACKGROUND. As life expectancy in the population rises, osteoporotic fractures are seen most frequently in the vertebral column. Percutaneous kyphoplasty is increasingly used for pain reduction and stabilization in these patients, but the efficacy, cost-effectiveness, and safety of the procedure remain uncertain. OBJECTIVE. To clarify whether kyphoplasty has additional value compared with optimum pain treatment in patients with acute vertebral fractures. MATERIALS & METHODS. From January 2004 to June 2009, 122 patients (31 males and 91 females), from 56 to 85 years old (mean age 68.5) were treated for 165 osteoporotic vertebral fractures of the thoracic or lumbar spine (minimum 15% height loss; level of fracture at Th5 or lower; bone oedema on MRI), with back pain for 6 weeks or less, and a visual analogue scale (VAS) score of 5 or more. Twelve patients (15 fractures) were lost at follow-up period and excluded. Patients were randomly allocated to percutaneous kyphoplasty (75 patients) or conservative treatment by computer-generated randomization codes. All fractures were analyzed for improvement in sagittal alignment (Cobb angle, kyphotic angle, sagittal index, vertebral height); and pain relief at 1, 6, 12, 24 months, as measured by VAS score. RESULTS. Percutaneous kyphoplasty resulted in direct and greater pain relief than did conservative treatment; difference in mean VAS score between baseline and 1 month was −6,5 after kyphoplasty and −2.4 after conservative treatment, and between baseline and 1 year was −7.2 after kyphoplasty and −3.8 after conservative treatment. No serious complications or adverse events were reported. Apart from the pain, the patient's ability to ambulate independently and without difficulty, and the need for medications improved significantly (P < 0.001) after kyphoplasty. Vertebral height significantly increased at all postoperative intervals, with 10% height increases in 88% of fractures, in kyphoplasty group at 2 years. There were no severe kyphoplasty-related complications, such as neurological defects, cement leakage or narrowing of the spinal canal whereas additional fractures occurred at the adjacent vertebrae at a rate of 10%. 35% of patients treated conservatively, had limitations in everyday activities the first 6 months, whereas additional fractures occurred at the adjacent vertebrae at a rate of 14%. CONCLUSION. In patients with acute osteoporotic vertebral compression fractures and persistent pain, balloon kyphoplasty is effective and safe. Pain relief after kyphoplasty is immediate, is sustained for at least 2 years, and is significantly greater than that achieved with conservative treatment, at an acceptable cost
