Aims

Using tibial shaft fracture participants from a large, multicentre randomized controlled trial, we investigated if patient and surgical factors were associated with health-related quality of life (HRQoL) at one year post-surgery.

Aims. The aims of this study were to identify and evaluate the current literature examining the prognostic factors which are associated with failure of total elbow arthroplasty (TEA). Methods. Electronic literature searches were conducted using MEDLINE, Embase, PubMed, and Cochrane. All studies reporting prognostic estimates for factors associated with the revision of a primary TEA were included. The risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool, and the quality of evidence was assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. Due to low quality of the evidence and the heterogeneous nature of the studies, a narrative synthesis was used. Results. A total of 19 studies met the inclusion criteria, investigating 28 possible prognostic factors. Most QUIPS domains (84%) were rated as moderate to high risk of bias. The quality of the evidence was low or very low for all prognostic factors. In low-quality evidence, prognostic factors with consistent associations with failure of TEA in more than one study were: the sequelae of trauma leading to TEA, either independently or combined with acute trauma, and male sex. Several other studies investigating sex reported no association. The evidence for other factors was of very low quality and mostly involved exploratory studies. Conclusion. The current evidence investigating the prognostic factors associated with failure of TEA is of low or very low quality, and studies generally have a moderate to high risk of bias. Prognostic factors are subject to uncertainty, should be interpreted with caution, and are of little clinical value. Higher-quality evidence is required to determine robust prognostic factors for failure of TEA. Cite this article: Bone Joint Res 2024;13(5):201–213

Aims. To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration. Methods. We performed a systematic literature search in MEDLINE, Embase, and Web of Science. The search string included multiple synonyms of the following keywords: "revision TKA", "outcome" and "prognostic factor". We searched for studies assessing the association between at least one prognostic factor and at least one outcome measure after rTKA surgery. Data on sample size, study design, prognostic factors, outcomes, and the direction of the association was extracted and included in an evidence map. Results. After screening of 5,660 articles, we included 166 studies reporting prognostic factors for outcomes after rTKA, with a median sample size of 319 patients (30 to 303,867). Overall, 50% of the studies reported prospectively collected data, and 61% of the studies were performed in a single centre. In some studies, multiple associations were reported; 180 different prognostic factors were reported in these studies. The three most frequently studied prognostic factors were reason for revision (213 times), sex (125 times), and BMI (117 times). Studies focusing on functional scores and patient-reported outcome measures as prognostic factor for the outcome after surgery were limited (n = 42). The studies reported 154 different outcomes. The most commonly reported outcomes after rTKA were: re-revision (155 times), readmission (88 times), and reinfection (85 times). Only five studies included costs as outcome. Conclusion. Outcomes and prognostic factors that are routinely registered as part of clinical practice (e.g. BMI, sex, complications) or in (inter)national registries are studied frequently. Studies on prognostic factors, such as functional and sociodemographic status, and outcomes as healthcare costs, cognitive and mental function, and psychosocial impact are scarce, while they have been shown to be important for patients with osteoarthritis.

Aims. Advances in treatment have extended the life expectancy of patients with metastatic bone disease (MBD). Patients could experience more skeletal-related events (SREs) as a result of this progress. Those who have already experienced a SRE could encounter another local management for a subsequent SRE, which is not part of the treatment for the initial SRE. However, there is a noted gap in research on the rate and characteristics of subsequent SREs requiring further localized treatment, obligating clinicians to extrapolate from experiences with initial SREs when confronting subsequent ones. This study aimed to investigate the proportion of MBD patients developing subsequent SREs requiring local treatment, examine if there are prognostic differences at the initial treatment between those with single versus subsequent SREs, and determine if clinical, oncological, and prognostic features differ between initial and subsequent SRE treatments. Methods. This retrospective study included 3,814 adult patients who received local treatment – surgery and/or radiotherapy – for bone metastasis between 1 January 2010 and 31 December 2019. All included patients had at least one SRE requiring local treatment. A subsequent SRE was defined as a second SRE requiring local treatment. Clinical, oncological, and prognostic features were compared between single SREs and subsequent SREs using Mann-Whitney U test, Fisher’s exact test, and Kaplan–Meier curve. Results. Of the 3,814 patients with SREs, 3,159 (83%) patients had a single SRE and 655 (17%) patients developed a subsequent SRE. Patients who developed subsequent SREs generally had characteristics that favoured longer survival, such as higher BMI, higher albumin levels, fewer comorbidities, or lower neutrophil count. Once the patient got to the point of subsequent SRE, their clinical and oncological characteristics and one-year survival (28%) were not as good as those with only a single SRE (35%; p < 0.001), indicating that clinicians’ experiences when treating the initial SRE are not similar when treating a subsequent SRE. Conclusion. This study found that 17% of patients required treatments for a second, subsequent SRE, and the current clinical guideline did not provide a specific approach to this clinical condition. We observed that referencing the initial treatment, patients in the subsequent SRE group had longer six-week, 90-day, and one-year median survival than patients in the single SRE group. Once patients develop a subsequent SRE, they have a worse one-year survival rate than those who receive treatment for a single SRE. Future research should identify prognostic factors and assess the applicability of existing survival prediction models for better management of subsequent SREs.

Background. Clinical guidelines recommend epidural steroid injection (ESI) as a treatment option for severe disc-related sciatica, but there is considerable uncertainty about its effectiveness. Currently, we know very little about factors that might be associated with good or poor outcomes from ESI. The aim of this systematic review was to synthesize and appraise the evidence investigating prognostic factors associated with outcomes following ESI for patients with imaging confirmed disc-related sciatica. Methods. The search strategy involved the electronic databases Medline, Embase, CINAHL Plus, PsycINFO and reference lists of eligible studies. Selected papers were quality appraised independently by two reviewers using the Quality in Prognosis Studies (QUIPS) tool. Between study heterogeneity precluded statistical pooling of results. Results. 2726 citations were identified; 11 studies were eligible. Overall study quality was low with all judged to have moderate or high risk of bias. Forty-five prognostic factors were identified but were measured inconsistently. The most commonly assessed prognostic factors were related to pain and function (n=7 studies), imaging features (n=6 studies), health and lifestyle (n=5 studies), patient demographics (n=4 studies) and clinical assessment findings (n=4 studies). No prognostic factor was found to be consistently associated with outcomes following ESI. Most studies found no association or results that conflicted with other studies. Conclusions. There is little, and low quality, evidence to guide practice in terms of factors that predict outcomes in patients following ESI for disc-related sciatica. The results can help inform some of the decisions about potential prognostic factors that should be assessed in future well-designed prospective cohort studies. Conflicts of interest: No conflicts of interest.

Aims. The aim of this study is to determine the predictors of overall survival (OS) and predictive factors of poor prognosis of conventional high-grade osteosarcoma of the limbs in a single-centre in South Africa. Methods. We performed a retrospective cross-sectional analysis to identify the prognostic factors that predict the OS of patients with histologically confirmed high-grade conventional osteosarcoma of the limbs over ten years. We employed the Cox proportional regression model and the Kaplan-Meier method for statistical analysis. Results. This study comprised 77 patients at a three-year minimum follow-up. The predictors of poor OS were: the median age of ≤ 19 years (hazard ratio (HR) 0.96; 95% confidence interval (CI) 0.92 to 0.99; p = 0.021); median duration of symptoms ≥ five months (HR 0.91; 95% CI 0.83 to 0.99; p < 0.037); metastasis at diagnosis (i.e. Enneking stage III) (HR 3.33; 95% CI 1.81 to 6.00; p < 0.001); increased alkaline phosphatase (HR 3.28; 95% CI 1.33 to 8.11; p < 0.010); palliative treatment (HR 7.27; 95% CI 2.69 to 19.70); p < 0.001); and amputation (HR 3.71; 95% CI 1.12 to 12.25; p < 0.032). In contrast, definitive surgery (HR 0.11; 95% CI 0.03 to 0.38; p < 0.001) and curative treatment (HR 0.18; 95% CI 0.10 to 0.33; p < 0.001) were a protective factor. The Kaplan-Meier median survival time was 24 months, with OS of 57.1% at the three years. The projected five-year event-free survival was 10.3% and OS of 29.8% (HR 0.76; 95% CI 0.52 to 1.12; p = 0.128). Conclusion. In this series of high-grade conventional osteosarcoma of the appendicular skeleton from South Africa, 58.4% (n = 45) had detectable metastases at presentation; hence, an impoverished OS of five years was 29.8%. Large-scale future research is needed to validate our results. Cite this article: Bone Jt Open 2024;5(3):210–217

Aims. The aim of this study was to develop and internally validate a prognostic nomogram to predict the probability of gaining a functional range of motion (ROM ≥ 120°) after open arthrolysis of the elbow in patients with post-traumatic stiffness of the elbow. Methods. We developed the Shanghai Prediction Model for Elbow Stiffness Surgical Outcome (SPESSO) based on a dataset of 551 patients who underwent open arthrolysis of the elbow in four institutions. Demographic and clinical characteristics were collected from medical records. The least absolute shrinkage and selection operator regression model was used to optimize the selection of relevant features. Multivariable logistic regression analysis was used to build the SPESSO. Its prediction performance was evaluated using the concordance index (C-index) and a calibration graph. Internal validation was conducted using bootstrapping validation. Results. BMI, the duration of stiffness, the preoperative ROM, the preoperative intensity of pain, and grade of post-traumatic osteoarthritis of the elbow were identified as predictors of outcome and incorporated to construct the nomogram. SPESSO displayed good discrimination with a C-index of 0.73 (95% confidence interval 0.64 to 0.81). A high C-index value of 0.70 could still be reached in the interval validation. The calibration graph showed good agreement between the nomogram prediction and the outcome. Conclusion. The newly developed SPESSO is a valid and convenient model which can be used to predict the outcome of open arthrolysis of the elbow. It could assist clinicians in counselling patients regarding the choice and expectations of treatment. Cite this article: Bone Joint J 2022;104-B(4):486–494

Aims. Patient-reported outcome measures have become an important part of routine care. The aim of this study was to determine if Patient-Reported Outcomes Measurement Information System (PROMIS) measures can be used to create patient subgroups for individuals seeking orthopaedic care. Methods. This was a cross-sectional study of patients from Duke University Department of Orthopaedic Surgery clinics (14 ambulatory and four hospital-based). There were two separate cohorts recruited by convenience sampling (i.e. patients were included in the analysis only if they completed PROMIS measures during a new patient visit). Cohort #1 (n = 12,141; December 2017 to December 2018,) included PROMIS short forms for eight domains (Physical Function, Pain Interference, Pain Intensity, Depression, Anxiety, Sleep Quality, Participation in Social Roles, and Fatigue) and Cohort #2 (n = 4,638; January 2019 to August 2019) included PROMIS Computer Adaptive Testing instruments for four domains (Physical Function, Pain Interference, Depression, and Sleep Quality). Cluster analysis (K-means method) empirically derived subgroups and subgroup differences in clinical and sociodemographic factors were identified with one-way analysis of variance. Results. Cluster analysis yielded four subgroups with similar clinical characteristics in Cohort #1 and #2. The subgroups were: 1) Normal Function: within normal limits in Physical Function, Pain Interference, Depression, and Sleep Quality; 2) Mild Impairment: mild deficits in Physical Function, Pain Interference, and Sleep Quality but with Depression within normal limits; 3) Impaired Function, Not Distressed: moderate deficits in Physical Function and Pain Interference, but within normal limits for Depression and Sleep Quality; and 4) Impaired Function, Distressed: moderate (Physical Function, Pain Interference, and Sleep Quality) and mild (Depression) deficits. Conclusion. These findings suggest orthopaedic patient subgroups differing in physical function, pain, and psychosocial distress can be created from as few as four different PROMIS measures. Longitudinal research is necessary to determine whether these subgroups have prognostic validity. Cite this article: Bone Jt Open 2021;2(7):493–502

This study was conducted to investigate the characteristics, complications, radiologic features and clinical course of patients undergoing reduction of forearm fractures in order to better inform patient prognosis and postoperative management. We conducted a retrospective cohort study of 1079 pediatric patients treated for forearm fractures between January 2014 and September 2021 in a 327 bed regional medical center. A preoperative radiological assessment and chart review was performed. Percent fracture displacement, location, orientation, comonution, fracture line visibility and angle of angulation were determined by AP and lateral radiographs. Percent fracture displacement was derived by: (Displacement of Bone Shafts / Diameter) x 100% = %Fracture Displacement. Angle of angulation and percent fracture displacement were calculated by averaging AP and lateral radiograph measurements. 80 cases, averaging 13.5±8.3 years, were identified as having a complete fracture of the radius and/or ulna with 69 receiving closed reduction and 11 receiving fixation via an intramedullary device or percutaneous pinning. Eight patients (10%) experienced complications with four resulting in a refracture and four resulting in significant loss of reduction (LOR) without refracture. Fractures in the proximal ⅔s of the radius were associated with a significant increase in complications compared to fractures in the distal ⅓ of the radius (31.6% vs 3.4%) (P=.000428). Likewise, a higher percent fracture displacement was associated with a decreased risk of complications (28.7% vs 5.9% displacement)(P=0.0403). No elevated risk of complications was found based on fracture orientation, angulation, fracture line visibility, forearm bone(s) fractured, sex, age or arm affected. Our result highlights radius fracture location and percent fracture displacement as markers with prognostic value following forearm fracture. These measurements are simply calculated via pre-reduction radiographs, providing an efficient method of informing risk of complications following forearm fracture

Abstract. Objectives. Ankle fractures have an incidence of around 90,000 per year in the United Kingdom. They affect younger patients following high energy trauma and, in the elderly, following low energy falls. Younger patients with pre-existing comorbidities including raised BMI or poor bone quality are also at risk of these injuries which impact the bony architecture of the joint and the soft tissues leading to a highly unstable fracture pattern, resulting in dislocation. At present, there is no literature exploring what effect ankle fracture-dislocations have on patients’ quality of life and activities of daily living, with only ankle fractures being explored. Methods. Relevant question formatting was utilised to generate a focused search. This was limited to studies specifically mentioning ankle injuries with a focus on ankle fracture-dislocations. The number of patients, fracture-dislocation type, length of follow up, prognostic factors, complications and outcome measures were recorded. Results. 939 fractures were included within the studies. Eight studies looked at previously validated foot and ankle scores, two primarily focused on the American Orthopaedic Foot and Ankle Society score (AOFAS), three on the Foot and Ankle Outcome Score (FAOS), and one study on the Olerud–Molander Score (OMAS). Patient, injury, and management factors were identified as being associated with poorer clinical outcomes. Conclusions. Not only are age and BMI a risk factor for posttraumatic osteoarthritis but they were also identified as prognostic indicators for functional outcome in this review. Patients sustaining a concurrent fracture-dislocation were found to have poorer clinical outcomes, and the timing and success of reduction further influenced outcomes. This review found that the quality of reduction was directly related to the patients’ functional outcomes post-follow up, and the risk of developing posttraumatic osteoarthritis, which was more frequent in patients sustaining Bosworth fractures, posterior malleolar fractures, and in patients over 35 years old

Aim. Determine therapeutic and prognostic value of three different prosthetic joint infections (PJI) staging systems – JS-Bach, McPherson and PJI-TNM. Method. Retrospective analysis of patients who received surgery for PJI between 2011 and 2022 at one single institution, including DAIR, 1-stage revision and 2-stage revision. We applied three staging systems - JS-Bach, McPherson, PJI-TNM – and categorize the results into A (less severe), B (intermediate) and C (most severe). Demographic data and comorbidities, anatomic location, type of treatment, recurrency of infection, final outcome and antibiogram were analyzed. Results. 186 patients were included, 112 (60%) were woman. Median age was 70 years old. 51% were submitted to DAIR, 10% to 1-stage revision and 39% to 2-stage revision. Recurrence of infection was found on 27% of patients after initial treatment. 10% died with complication related to PJI. Final status at last follow-up showed 96% of cases were ultimately free of infection at last follow-up. JS-BACH was associated with recurrence. All three staging systems were associated with final outcome. Conclusions. Despite all existing knowledge around risk factors for treatment failure of PJI, there is still a lack of a generally accepted classification system to accurately predict patient outcome. JS-BACH, McPherson and PJI-TNM are three different proposed classifications developed to predict clinical outcomes. To the best of our knowledge there are no studies directly comparing their performance. We retrospectively evaluated our cohort and found that all three correlated with final patient outcome but JS-BACH was the only who significantly correlated with infection recurrence after initial treatment

Growth factors are reported to play an important role in healing after acute Achilles tendon rupture (ATR). However, the association between growth factors and patient outcome has not been investigated previously. The aim of this retrospective study is to identify growth factors and related proteins which can be used as predictors of healing after ATR, ethical approval was obtained from the Regional Ethical Review Committees in Sweden and followed the guidelines of the Declaration of Helsinki. The study included 28 surgically treated patients (mean age 39.11 ± 8.38 yrs) with acute ATR. Healing was assessed by microdialysate two weeks after the surgery and performed on both injured and contralateral un-injured leg. The microdialysates were analyzed by proteomics based on mass spectrometry (MS) to detect growth factor expressions in ATR patients. One year after the surgery, healing outcomes were evaluated by patient-reported Achilles tendon Total Rupture Score (ATRS), Foot and Ankle Outcome Score (FAOS), and functional outcomes by heel-rise test. A total of 1549 proteins were detected in the microdialysates of which 20 growth factor/ related proteins were identified. 7 of these were significantly up-regulated (IGFBP2, Fold change (FC) = 4.07, P = 0.0036; IGFBP4, FC = 3.06, P = 0.009; CTGF, FC = 15.83, P = 0.003; HDGF, FC = 4.58, P = 0.003; GRB2, FC = 14.8, P = 0.0004; LTBP1, FC = 12.08, P = 0.0008; TGFBI, FC = 5.54, P = 0.001) and 1 down-regulated (IGFBP6) in the injured compared to the contralateral healthy side. Linear regression analysis revealed that TGFB1 was positively associated with improved ATRS (r = 0.585, P = 0.04) as well to ATRS subscales: less limitation in running (r = 0.72, P = 0.004), less jumping limitation (r = 0.764, P = 0.001) and less limitation caused by decreased tendon strength (r = 0.665, P = 0.012). Interestingly, all 7 up-regulated proteins were positively associated with less jumping limitations (IGFBP2, r = 0.667, P = 0.015; IGFBP4, r = 0.675, P = 0.013; CTGF, r = 0.668, P = 0.015; HDGF, r = 0.672, P = 0.014; GRB2, r = 0.665, P = 0.016; LTBP1, r = 0.663, P = 0,016). No associations were observed among any of the growth factor and FAOS or patient's functional outcomes. We conclude that growth factors and related proteins play a crucial role in ATR healing. More specifically, TGFB1 may be used as prognostic biomarker of the patient-reported outcome 1-year post-surgery. These results may be used to develop more specific treatments to improve ATR healing

The modified Glasgow Prognostic Score (mGPS) is a validated prognostic indicator in various carcinomas as demonstrated by several meta-analyses. The mGPS includes pre-operative CRP and albumin values to calculate a score from 0–2 that correlates with overall outcome. Scores of 2 are associated with a poorer outcome. Our aim was to assess if the mGPS is reliable as a prognostic indicator for soft tissue sarcoma (STS) patients. All patients with a STS diagnosed during years 2010–2014 were identified using our prospectively collected MSK oncology database. We performed a retrospective case note review examining demographics, preoperative blood results and outcomes (no recurrence, local recurrence, metastatic disease and death). 94 patients were included. 56% were female and 53% were over 50 years. 91% of tumours were high grade (Trojani 2/3) and 73% were >5cm. 45 patients had an mGPS score of 0, 16 were mGPS 1 and 33 were mGPS 2. On univariate analysis, an mGPS of 0 or 2 was statically significant with regards to outcome (p=0.012 and p=0.005 respectively). We have demonstrated that pre-treatment mGPS is an important factor in predicting oncological outcome. A score of 0 relates to an improved prognosis whilst a score of 2 relates to an increased risk of developing metastases and death. mGPS as a prognostic indicator was not affected by either the tumour size or grade. We believe that a pre-operative mGPS should be calculated to help predict oncological outcome and in turn influence management. Further work is being undertaken with a larger cohort

Aim: To identify prognostic factors for patients with sarcomas. Method: A retrospective analysis of all patients with newly diagnosed referred to a specialist musculoskeletal tumour centre, with a minimum 5 year follow up. Factors affecting survival and recurrence were identified. Results: There were 1175 patients with soft tissue sarcomas and the most common diagnoses were liposarcoma (22%) followed by mfh (12%) and leiomyosarcoma (11%). 55% were high grade, 25% intermediate and 20% low grade. The most common site was the thigh (44%). 9% had metastases at diagnosis and of these only 10% survived 5 years. Prognostic factors were analyzed in the remaining 1075 patients. The 5 year disease specific survival was 87% for low grade, 66% for intermediate grade and 48% for high grade sarcomas. Prognostic factors (p< 0.05) on univariate analysis were grade, depth, size, age, sex, wide margins of excision, limb salvage (vs amputation), having had a previous excision (whoops). Many of these factors however were inter-related and on multivariate analysis it was found that the following were still significant: Grade, size, depth, age and buttock location (all p< 0.0005). There were 2320 bone tumours (954 with osteosarcoma, 454 with chondrosarcoma and 463 with Ewings). Prognostic factors for all tumours were size, good response to chemotherapy and limb salvage (as opposed to amputation). Conclusion: This study has confirmed the generally held factors for prognosis of sarcomas. It is largely tumour factors, not treatment factors which dictate outcome. Of all the factors leading to a poor prognosis, size is the only one which can appreciably be altered – by earlier diagnosis

Purpose of the study: To analyze survival and prognostic factors in a series of patients treated for chondrosarcoma of the pelvis. Material and methods: The series included 106 patients (53 women and 53 men) treated for non-metastatic chondrosarcoma of the pelvis. Minimum follow-up was two years. Mean age at diagnosis was 44 years. Tumors were grade 1 (n=47), grade 2 (n=37), grade 3 (n=22). Conservative surgery was performed in 73 patients (resection with or without reconstruction) and interilio-abdominal disarticulation for 33. Results: Resection margins were sufficient for 34 patients (wide or radical resection), marginal for 35, and intratumoral or malignant for 37. Local recurrence was noted in 39 patients (37%). Prognostic factors affecting local recurrence were: quality of resection (p=0.03), grade (p=0.01). Overall survival at 5, 10 and 15 years were 72, 56, and 46% respectively. Survival was strongly correlated with grade (p=0.08) and survival after five years was also correlated with resection margins. Conclusions: In this series, tumor grade was the most important prognostic factor for patients with chondrosarcoma of the pelvis but achieving satisfactory resection with wide margins also has a significant effect on prognosis for local recurrence and long-term survival

Spinal metastases are seen in 10–30% of cancer patients. Twenty percent of these metastases occur in the lumbo-sacral spine. Lumbo-sacral spine has different mechanical properties and encloses the cauda equina. Few studies took interest in this spinal segment. The objective of this study is to evaluate prognostic factors of lumbo-sacral spinal metastasis treated in our center. We retrospectively reviewed 376 patients who were operated in our center from 2010 to 2018. Eighty-nine patients presented lumbo-sacral metastases and thus were included. Data collected included age, smoking, tumor histology, American spinal injury association (ASIA) score, modified Tokuhashi score, modified Bauer score, ambulation status and adjuvant treatment. The mean population age was 60.9 years old (35–85). The tumor histology was predominantly lung (19 patients, 21.3%), breast (13 patients, 14.6%), kidney (11 patients, 12.4%) and prostate (9 patients 10.1%). Twenty-two patients (24.7%) were unable to walk preoperatively. Seventy-nine patients (88.8%) underwent a posterior open approach with corpectomy in 65 patients (73%). Eighteen patients regained ambulation post-operatively (81.8%). The mean survival was 24.03 months (CI95% 17,38–30,67, Range 0–90) and the median of survival was 9 months (CI95% 4.38–13.62). Better preoperative ASIA score had a significant favorable effect (p=0.03) on survival. Patients who regained their ability to walk had better survival (25.1 months (CI95% 18.2–32) VS 0.5 months (CI95% 0–1.1). Postoperative radiotherapy had a benefic effect on survival (p=0.019): Survival Increased from 10.5 months (CI95% 2.4–18.7) to 27.6 months (CI95% 19.5–35.8). The modified Tokuhashi and the modified Bauer scores underestimated the survival of the patients with lumbosacral metastases. Lumbosacral spinal metastases has better survival than expected by Tokuhashi and Bauer score. Surgical procedure have an important impact on survival and the ability to walk

To assess how effective are the prognostic scores and the role of delayed presentation in predicting the outcomes in patients with metastatic spine disease. Retrospectively data collected from December 2006 to December 2009. Medical records review included types of tumours, duration of symptoms, duration from referral to definitive treatment, expected survival, functional status before and after treatment. Karnofsky performance score and Modified Tokuhashi were used. Results: 50 patients underwent surgical stabilisation for metastatic spine disease with or with out cord compression. Age ranged from 39 to 87 years (Avg: 64). Patients had four main types of tumours; (Myeloma 30%, Lymphoma 22% Lung CA 16% and Renal 12 %). Inpatients without cord compression, the average time from referral to definitive treatment is 17 days. Over all fictional status improved in 70% of cases following surgical intervention. Patients who presented with cord compression had surgery with in 49 hours. Patients with high prognostic scores did not survive as long as expected. On the contrary, patients with poor prognostic scores survived longer than expected. This discrepancy is significant in patients with lung and renal malignancies. Patients with Myeloma did well as per the prognostic scores. Prognostic scores are not uniformly effective in all types of malignancies. Factors like delayed presentation and general condition were not included in the prognostic factors. Hence, we conclude that we cannot make a decision purely based on the prognostic scores to perform either palliative or definitive surgery

Introduction We have undertaken a retrospective study to identify prognostic factors predictive of neurological recovery after spinal cord injury (SCI). Methods During the year 1999 to 2000, 403 patients with SCI were admitted and 91 patients could be followed-up for more than one year. Improvement in the motor score (ASIA) were taken as indicative of functional neurological recovery. Prognostic factors were simplified into static (which do not change with time) and dynamic (which may change with time). Variables like age, sex, mode of injury, mechanism of injury and skeletal level were static. Neurological level, sacral sparing, duration of spinal shock, reflex recovery, sensory & motor scores and complications like bedsores, flexor spasms, UTI, URTI, & DVT were dynamic. These were recorded at admission, at weekly intervals until discharge and at three monthly intervals in follow-up. They were correlated for any association with neurological recovery at one year. Regressive analysis of static and dynamic factors was done. Results No significant correlation of static variables with the neurological recovery was found. First aid and transportation, duration of spinal shock, sacral sparing, rate of reflex recovery, flexor spasms and bedsores had a significant correlation with neurological recovery. Pin-prick sparing, spinal shock of < 24 hours and early appearance of deep tendon reflexes were good prognostic factors. Complete lesion, spinal shock for > 1 week, flexor spasms within three weeks and bedsore within one week were worst prognostic factor. Initial three weeks following injury was the critical period influencing final neurological and functional outcome

Synovial sarcoma is a morphologically well-defined neoplasm that most commonly occurs in soft tissue accounting for 5% to 10 % of all soft tissue sarcomas. We reviewed 156 patients with synovial sarcoma of soft tissues treated at a supra-regional centre to determine survival and prognostic factors. There were 77men and 79 women with mean age at presentation of 38 years (3 to 84). Follow-up periods ranged from 3 to 494 months (median 43 months). Tumor was located in lower extremities in 111patients, upper extremities in 34 patients, and trunk and pelvis in 11 patients. Overall survival was 66% at 5 years and 48% at 10 years. The 5 and 10 year survival for the 23 patients who had metastases at the time of diagnosis was 13% and 0% respectively compared to 75% and 54% for those without metastases at diagnosis. Local recurrence occurred in 18 patients (13%). The significant prognostic factors for survival included presence of metastases at diagnosis and development of local recurrence. Tumour size and depth, age of patients and use of chemotherapy did not significantly influence survival. We conclude that the clinical factors which influence survival of patients with synovial sarcoma are different from those of soft tissue sarcomas in general. Biological factors may better predict prognostic survival than the usual clinical factors

Background. There is a paucity of prognosis research in patients with neuropathic low back-related leg pain (LBLP) in primary care. Purpose. To investigate the clinical course and prognostic factors in primary care LBLP patients consulting with neuropathic pain (NP). Methods. LBLP patients in a primary-care cohort study (n=606) completed the self-report version of Leeds Assessment for Neurological Symptoms and Signs (s-LANSS, score of ≥12 indicates possible NP) at baseline and 4-months. Mixed effects models compared pain-intensity (highest of mean leg or mean back pain - 0–10 NRS at baseline, 4-months, 12-months and 3-years) between those with persistent NP (s-LANSS ≥12 at baseline and 4-months) and those without (s-LANSS ≥12 at baseline and <12 at 4-months). Univariable and multivariable binary logistic regression examined association between potential prognostic factors (chosen from baseline self-report questionnaires, clinical examination, MRI scan findings) and persistent NP. Multiple imputation was used to account for missing data. Results. 44% (72/164) of patients with NP at baseline had persistent NP at 4-months. Mean pain intensity of patients with persistent NP was higher at 4-months, 12-months and 3-years compared to those without. In univariable analysis, only pain self-efficacy was significantly associated with persistent NP (OR 0.98, 95% CI 0.96 to 0.998). In multivariable analysis, none of the 7 investigated factors were significantly associated with persistent NP. Conclusion. Patients with persistent NP were consistently worse-off up to 3-years follow-up compared to those without. It was difficult to identify those patients with NP at baseline who would have persistent NP at 4-months. No conflicts of interest.
