Aims. This study assessed the association of classes of body mass index in kg/m. 2. (classified as normal weight 18.5 kg/m. 2 . to 24.9 kg/m. 2. , overweight 25.0 kg/m. 2 . to 29.9 kg/m. 2. , and obese ≥ 30.0 kg/m. 2. ) with short-term complications and functional outcomes three to six years post-operatively for closed ankle fractures. Patients and Methods. We performed a historical cohort study with chart review of 1011 patients who were treated for ankle fractures by open reduction and internal fixation in two hospitals, with a follow-up postal survey of 959 of the patients using three functional outcome scores. Results. Obese patients had more severe overall complications and higher odds of any complication than the normal weight group, with adjusted odds ratio 1.67 (95% confidence interval (CI) 1.08 to 2.59; p = 0.021) and 1.71 (95% CI 1.10 to 2.65; p = 0.016), respectively. In total 479 patients (54.6%) responded to the questionnaire. Obese patients had worse scores on the Olerud and Molander Ankle Score (p < 0.001), Self-Reported Foot and Ankle Questionnaire (p = 0.003) and Lower Extremity Functional Scale (p = 0.01) than those with normal weight. In contrast, overweight patients did not have worse functional scores than those with normal weight. Conclusion. Obese patients had more complications, more severe complications, and worse functional outcomes three to six years after ankle surgery compared with those with normal weight.

We performed a systematic review of the literature to evaluate the use and interpretation of generic and disease-specific functional outcome instruments in the reporting of outcome after the surgical treatment of disruptions of the pelvic ring. A total of 28 papers met our inclusion criteria, with eight reporting only generic outcome instruments, 13 reporting only pelvis-specific outcome instruments, and six reporting both. The Short-Form 36 (SF-36) was by far the most commonly used generic outcome instrument, used in 12 papers, with widely variable reporting of scores. The pelvis-specific outcome instruments were used in 19 studies; the Majeed score in ten, Iowa pelvic score in six, Hannover pelvic score in two and the Orlando pelvic score in one. Four sets of authors, all testing construct validity based on correlation with the SF-36, performed psychometric testing of three pelvis-specific instruments (Majeed, IPS and Orlando scores). No testing of responsiveness, content validity, criterion validity, internal consistency or reproducibility was performed.

The existing literature in this area is inadequate to inform surgeons or patients in a meaningful way about the functional outcomes of these fractures after fixation.

Aims. We introduced a self-care pathway for minimally displaced distal radius fractures, which involved the patient being discharged from a Virtual Fracture Clinic (VFC) without a physical review and being provided with written instructions on how to remove their own cast or splint at home, plus advice on exercises and return to function. Methods. All patients managed via this protocol between March and October 2020 were contacted by a medical secretary at a minimum of six months post-injury. The patients were asked to complete the Patient-Rated Wrist Evaluation (PRWE), a satisfaction questionnaire, advise if they had required surgery and/or contacted any health professional, and were also asked for any recommendations on how to improve the service. A review with a hand surgeon was organized if required, and a cost analysis was also conducted. Results. Overall 71/101 patients completed the telephone consultation; no patients required surgery, and the mean and median PRWE scores were 23.9/100 (SD 24.9) and 17.0/100 (interquartile range (IQR) 0 to 40), respectively. Mean patient satisfaction with treatment was 34.3/40 (SD 9.2), and 65 patients (92%) were satisfied or highly satisfied. In total there were 16 contact calls, 12 requests for a consultant review, no formal complaints, and 15 minor adjustment suggestions to improve patient experience. A relationship was found between intra-articular injuries and lower patient satisfaction scores (p = 0.025), however no relationship was found between PRWE scores and the nature of the fracture. Also, no relationship was found between the type of immobilization and the functional outcome or patient satisfaction. Cost analysis of the self-care pathway V traditional pathway showed a cost savings of over £13,500 per year with the new self-care model compared to the traditional model. Conclusion. Our study supports a VFC self-care pathway for patients with minimally displaced distal radius fractures. The pathway provides a good level of patient satisfaction and function. To improve the service, we will make minor amendments to our patient information sheet. Cite this article: Bone Jt Open 2022;3(9):726–732

Aims. Acetabular fractures in older adults lead to a high risk of mortality and morbidity. However, only limited data have been published documenting functional outcomes in such patients. The aims of this study were to describe outcomes in patients aged 60 years and older with operatively managed acetabular fractures, and to establish predictors of conversion to total hip arthroplasty (THA). Methods. We conducted a retrospective, registry-based study of 80 patients aged 60 years and older with acetabular fractures treated surgically at The Alfred and Royal Melbourne Hospital. We reviewed charts and radiological investigations and performed patient interviews/examinations and functional outcome scoring. Data were provided by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Survival analysis was used to describe conversion to THA in the group of patients who initially underwent open reduction and internal fixation (ORIF). Multivariate regression analyses were performed to identify factors associated with conversion to THA. Results. Seven patients (8.8%) had died at a median follow-up of 18 months (interquartile range (IQR) 12 to 25), of whom four were in the acute THA group. Eight patients (10%) underwent acute THA. Of the patients who underwent ORIF, 17/72 (23.6%) required conversion to THA at a median of 10.5 months (IQR 4.0 to 32.0) . After controlling for other factors, transport-related cases had an 88% lower rate of conversion to THA (hazard ratio (HR) 0.12, 95% confidence interval (CI) 0.02 to 0.91). Mean standardized Physical Component Summary Score (PCS-12) of the 12-Item Short Form Health Survey (SF-12) was comparable with the general population (age-/sex-matched) by 12 to 24 months. Over half of patients working prior to injury (14/26) returned to work by six months and two-thirds of patients (19/27) by 12 months. Conclusion. Patients over 60 years of age managed operatively for displaced acetabular fractures had a relatively high mortality rate and a high conversion rate to THA in the ORIF group but, overall, patients who survived had mean PCS-12 scores that improved over two years and were comparable with controls.

The aim of this study was to define the long-term outcome following adolescent clavicle fracture. We retrospectively reviewed all adolescent fractures presenting to our region (13–17years) over a 10-year period. Patient reported outcomes were undertaken at a minimum of 4 years post-injury (QuickDASH and EQ-5D) in completely displaced midshaft fractures (Edinburgh 2B, >2cm displacement, n=50) and angulated midshaft fractures (Edinburgh 2A2, >30 degrees angulation, n=32). 677 clavicle fractures were analysed. The median age was 14.8 (IQR 14.0–15.7) and 89% were male. The majority were midshaft (n=606, 89.5%) with either angulation (39.8%) or simple fully displaced (39.1%). Only 3% of midshaft fractures underwent acute fixation (n=18/606), all of which were fully displaced. The incidence of refracture following non-operative management of midshaft fractures was 3.2% (n=19/588), all united with non-operative management. Fracture type, severity of angulation or displacement was not associated with risk of refracture. There was one case of non-union encountered following non-operative management of all displaced midshaft fractures (0.4%, n=1/245). At a mean of 7.6 years following injury, non-operative management of both displaced and angulated fractures had a median QuickDASH was 0.0 (IQR 0.0–2.3), EQ-5D was 1.0 (IQR 1.0–1.0). 97% of angulated fractures and 94% of displaced fractures were satisfied with their final shoulder function. We conclude that Non-operative management of adolescent midshaft clavicle fractures result in excellent functional outcomes with a low rate of complications at long-term follow up. The relative indications for surgical intervention for clavicle fractures in adults do not appear to be applicable to adolescents

We performed a systematic review of the literature pertaining to the functional outcomes of the surgical management of acetabular fractures. A total of 69 articles met our inclusion criteria, revealing that eight generic outcome instruments were used, along with five specific instruments. The majority of studies reported outcomes using a version of the d’Aubigne and Postel score, which has not been validated for use in acetabular fracture. Few validated outcome measures were reported. No psychometric testing of outcome instruments was performed. The current assessment of outcomes in surgery for acetabular fractures lacks scientific rigour, and does not give reliable outcome data for either scientific comparison or patient counselling. Take home message: The use of non-validated functional outcome measures is a major limitation of the current literature pertaining to surgical management of acetabular fractures; future studies should use validated outcome measures to ensure the legitimacy of the reported results.

Introduction. Distal tibial fractures are notoriously difficult to treat and a lack of consensus remains on the best approach. This study examined clinical and functional outcomes in such patients treated definitively by circular external fixation (Ilizarov). Patients and Methods: Between July 2011 and May 2016, patients with fractures extending to within 1 muller square of the ankle were identified from our prospective Ilizarov database. Existing data was supplemented by review of clinical records. Fractures were classified according to the AO/OTA classification. Functional outcome data, including general measures of health related quality of life (SF-12 and Euroqol) and limb specific scores (Olerud and Molander Score and Lysholm scores) had been routinely collected for part of the study period. Patients in whom this had not been collected were asked to complete these by post. Adverse events were documented according to Paley's classification of: problems, obstacles and complications. Results. 142 patients with 143 fractures were identified, 40 (28%) were open, 94 (66%) were intra-articular, 85 (59%) were tertiary referrals. 32% were type 1, 28%, type 2 and 40% type 3 AO/OTA severity. 139 (97%) of the fractures united (2 non-unions, 1 amputation and 2 delayed unions who remain in frames), at a median of 165 days (range 104 to 429, IQR 136 to 201). 62% united by 6 months, 87% by 9 months and 94% by 1 year. Both non-unions have united with further treatment. Closed fractures united more rapidly than open (median 157 vs 185 days; p=0.003) and true Pilon (43C3) fractures took longer to unite other fractures (median 156 vs 190 days; p<0.001). 34% of patients encountered a problem, 12% an obstacle and 10% a complication. Of the complications, 6 (4%) were minor, 5 (3.5%) major not interfering with the goals of treatment and 4 (3%) major interfering with treatment goals (including the 2 patients with non-union and 1 who underwent amputation as well as 1 significant mal-union). This will increase to 4% if the 2 delayed unions fail to unite. Overall 56% reported good or excellent ankle scores at last report, 28% fair and 16% poor. Closed, extra-articular and non-43C3 fractures had better functional outcome scores than open, intra-articular and 43C3 fractures respectively. Conclusions. This study demonstrates a high union and low serious complication rate, suggesting that external ring fixation is a safe and effective treatment for these injuries. *Judged best paper*

Aims. The aim of this study was to determine the trajectory of recovery following fixation of tibial plateau fractures up to five-year follow-up, including simple (Schatzker I-IV) versus complex (Schatzker V-VI) fractures. Patients and Methods. Patients undergoing open reduction and internal fixation (ORIF) for tibial plateau fractures were enrolled into a prospective database. Functional outcome, using the 36-Item Short Form Health Survey Physical Component Summary (SF-36 PCS), was collected at baseline, six months, one year, and five years. The trajectory of recovery for complex fractures (Schatzker V and VI) was compared with simple fractures (Schatzker I to IV). Minimal clinically important difference (MCID) was calculated between timepoints. In all, 182 patients were enrolled: 136 (74.7%) in simple and 46 (25.3%) in complex. There were 103 female patients and 79 male patients with a mean age of 45.8 years (15 to 86). Results. Mean SF-36 PCS improved significantly in both groups from six to 12 months (p < 0.001) and one to five years (simple, p = 0.008; complex, p = 0.007). In both groups, the baseline scores were not reached at five years. The SF-36 PCS was significantly higher in the simple group compared with the complex group at both six months (p = 0.007) and 12 months (p = 0.01), but not at five years (p = 0.17). Between each timepoint, approximately 50% or more of the patients in each group achieved an MCID in their score change, indicating a significant clinical change in condition. The complex group had a much larger drop off in the first six months, with comparable proportions achieving MCID at the subsequent time intervals. Conclusion. Tibial plateau fracture recovery was characterized overall by an initial decline in functional outcome from baseline, followed by a steep improvement from six to 12 months, and ongoing recovery up to five years. In simple patterns, patients tended to achieve a higher functional score by six months compared with the complex patterns. However, comparable functional scores between the groups achieved only at the five-year point suggest later recovery in the complex group. Function does not improve to baseline by five years in either group. This information is useful in counselling patients about the course of prospective recovery.

Introduction. Metal on metal hip resurfacing (MMHR) has been advocated for the younger patient for several reasons including for the preservation of bone stock and ease of revision to total hip replacement (THR), thus ‘buying an additional operation’ for the patient. This rationale however assumes a good functional outcome after the revision to a THR and that the results of the ‘revision primary’ will not be compromised by the resurfacing which preceded it. We present our data on a consecutive series of 68 revised MMHRs. Methods. Between September 1997 and September 2009, 927 consecutive patients underwent a hip resurfacing procedure performed by one of three senior surgeons at our institution. The Cormet resurfacing system was used for all patients. Sixty-eight of these patients had their resurfacing revised. Oxford hip score (OHS) obtained at a minimum of 12 months follow-up was used as the primary outcome measure. Results. Average age at time of index procedure was 51.9 (24 to 68) years. The MMHRs were revised an average of 49 (1 to 121) months after index procedure. At time of writing OHS post revision was 21.4 (range 12 to 48) at an average of 42 months post revision (range 16 to 111 months). Patients with a primary diagnosis of dysplasia were at an increased risk of revision RR 3.7 (1.9–7.1, p < 0.05).). No other primary diagnosis significantly increased risk of revision. Five patients underwent a second revision procedure. Discussion. We present the fuctional outcome scores of a large series of revised MMHRs. Despite MMHRs offering the advantage of preservation of bone stock we have found revision of MMHRs to THRs technically difficult. Our functional outcome scores in patients post revision were disappointing. We cannot support the concept that MMHR “buys patients another operation”

Our aim was to correlate the health status with objective and radiological outcomes in patients treated by open reduction and internal fixation for fractures of both bones of the forearm. We assessed 23 patients (24 fractures) subjectively, objectively and radiologically at a mean of 34 months (11 to 72). Subjective assessment used the disability of the arm, shoulder and hand (DASH) and musculoskeletal functional attachment (MFA) questionnaires. The range of movement of the forearm and wrist, grip and pinch strength were measured objectively and standardised radiographs were evaluated. In general, patients reported good overall function based on the DASH (mean 12; range 0 to 42) and MFA (mean 19; range 0 to 51) scores. However, pronation and grip and pinch strength were significantly decreased (p < 0.005). These deficiencies correlated with poorer subjective outcomes. Operative stabilisation of fractures of the radius and ulna led to a reliably acceptable functional outcome. However, despite these generally satisfactory results, the outcome scores worsened with reduction in the range of movement of the forearm and wrist

Triple arthrodesis is the most effective treatment resource for restoring shape and stability to the hind-foot. It is used in order to achieve a plantigrade foot, aligned, stable and painless, in the treatment of various pathologies. However, it has the effect of changing the dynamic mobility of the foot and diminishes the adapting ability to uneven ground, influencing the outcome. Opinions differ on the necessity of internal fixation to maintain the proper alignment of the hind-foot and improve consolidation, influencing the results. The authors reviewed the patients who underwent triple arthrodesis between 01/01/1998 and 31/12/2008. Of a total of 46 patients 28 were reviewed, corresponding to 29 feet that underwent 36 interventions (7 recurrences). Patients were divided into two groups according to whether or not the placement of internal fixation. They were evaluated according to the AOFAS ankle and hindfoot score and correlated with the radiologic result. The most frequent indications for surgery were osteoarthrosis of the tarsus and sequelae of fractures of the calcaneus. In the group without fixation 68% had radiological signs of consolidation. 24% required revision for non consolidation. In the group with internal fixation there was 72.7% consolidation and 9.1% required revision surgery. Bone graft was more often used in internal fixation group (72.7% vs 40%). Group without fixation vs group with internal fixation:. AOFAS mean score: 74.5% vs 61.6%, patients without pain: 50% vs 20%; plantigrade foot with good alignment: 66.7% vs 40% without pain: 50% vs 20%; tibiotarsal arthritis: 48% vs 63.6%; Lisfranc arthrosis: 44% vs 63.6%. There is a higher rate of consolidation in the group setting. However, the functional outcome seems to be better in the group without fixation. Fixation seems to be associated with better consolidation. The functional outcome is related to a plantigrade and well aligned foot

The purpose of this study was to evaluate the subjective and objective functional outcome after osteosynthesis of the forearm bone fractures with plates and screws (ORIF) or elastic nailing (CRIF). We evaluated 55 patients (45 men and 10 women) who underwent internal fixation of both forearm bones with CRIF or ORIF, concerning the range of motion of the forearm, wrist and elbow (pronation, supination, flexion and extension), grip strength and a validated outcome measure (DASH score). The mean duration of follow-up was 3 years, and standardized radiographs of the forearm were evaluated. The mean age was 41.6. We used the Student's t test to compare means and chi-square test to compare proportions. The mean (confidence interval 95%) of the DASH scale was 29.6 (22.6 to 36.5), significantly higher (p<0.001) than the normative value in the U.S. (10.1). There was a statistically significant reduction of forearm supination (86.4 vs. 64.6, p<0.001) and grip strength (0.63 vs. 0.48, p<0.001) in relation to the opposite member; grip strength decrease correlated with worse subjective outcome (p<0.02). There were no significant differences between groups undergoing ORIF or CRIF. The risk of nonunion and reintervention was not different between groups (p=0214). Forearm bones fractures are associated with high rates of consolidation and satisfactory mobility of the forearm since we obtain an anatomic reduction of the fracture, as is most easily achieved by plate fixation. However, elastic nailing is a less invasive technique that allows restoring function more quickly with less pain and no increased risk of complications. Given the scant scientific evidence currently available we will require a more comprehensive study to compare the anatomical and functional outcome after ORIF and CRIF

This study assessed whether patient satisfaction with their hospital stay influences the early outcome of total knee replacement (TKR). During a five year period patients undergoing primary TKR at the study centre had prospectively outcome data recorded (n=2264). Patients with depression (p=0.04) and worse mental wellbeing (p<0.001), according to the short form (SF)-12, were more likely to be dissatisfied with their hospital stay. Decreasing level of satisfaction with their hospital stay was associated with a significantly worse post-operative OKS (p<0.001) and SF-12 score (p<0.001). Multivariable regression analysis confirmed that the patients perceived level of satisfaction with their hospital stay was an independent predictor of change in the OKS (p<0.001) and SF-12 score (p<0.001) after adjusting for confounding variables. Patient satisfaction with their TKR was significantly influenced by their hospital experience, decreasing from 96% in those with an excellent experience to 42% in those with a poor experience. Food, staff/care, and the hospital environment were the most frequent reasons of why patients rated their hospital experience as fair or poor. A patient's perception of their inpatient hospital experience after surgery is an important modifiable predictor of early functional outcome and satisfaction with TKR

There is clear evidence to support removal of the calcific deposit in patients with calcific tendonitis, however, there is conflicting evidence as to whether concomitant subacromial decompression (SAD) is of benefit to the patient. The aim of this study was to conduct a prospective double blind randomised control trial to assess the independent effect of SAD upon the functional outcome of arthroscopic management of calcific tendonitis. During a four year period 80 patients (power calculation was performed) were recruited to the study who presented with acute calcific tendonitis of the shoulder. Forty patients were randomised to have SAD and 40 were randomised not to have a SAD in combination with arthroscopic decompression of the calcific deposit. All surgery was performed by the senior author who was blinded to the functional assessment of the patients. There were 21 male and 59 female patients with a mean age of 48.9 (32 to 75) years. The pre-operative short form 12 physical component summary (PCS) was 39.8 and the mental component summary was 52.6, disability arm should and hand (DASH) score was 34.5, and the Constant score (CS) was 45.7. Both groups had a significant improvement in the PCS, DASH, CS at 6 weeks and at one year compared to their pre-operative scores (p<0.001). There were no significant differences demonstrated between the groups for any of the outcome measures assessed at 6 weeks or at one year. SAD should not be routinely performed as part of the arthroscopic management of acute calcific tendonitis

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)

Aims

There is no consensus on the treatment of proximal humeral fractures. Hemiarthroplasty has been widely used in patients when non-surgical treatment is not possible. There is, despite extensive use, limited information about the long-term outcome. Our primary aim was to report ten-year patient-reported outcome after hemiarthroplasty for acute proximal humeral fractures. The secondary aims were to report the cumulative revision rate and risk factors for an inferior patient-reported outcome.

The treatment of massive rotator cuff tears remains controversial. There is lack of studies comparing patient-reported outcomes (PROM) of arthroscopic massive rotator cuff repairs (RCR) against large, medium and small RCRs. Our study aims to report the PROM for arthroscopic massive RCR versus non-massive RCR.

Patients undergoing an arthroscopic RCR under a single surgeon over a 5-year period were included. Demographic data were recorded. Pre-operative Quick-DASH and Oxford Shoulder Score (OSS) were prospectively collected pre-operatively and at final review (mean of 18 months post-operatively). The scores were compared to a matched cohort of patients who had large, medium or small RCRs. A post-hoc power analysis confirmed 98% power was achieved.

82 patients were included in the study. 42 (51%) patients underwent massive RCR. The mean age of patients undergoing massive RCR was 59.7 and 55% (n=23) were female. 21% of massive RCRs had biceps augmentation. Quick-DASH improved significantly from a mean of 46.1 pre-operatively to 15.6 at final follow-up for massive RCRs (p<0.001). OSS improved significantly from a mean of 26.9 pre-operatively to 41.4 at final follow up for massive RCRs (p<0.001). There was no significant difference in the final Quick-DASH and OSS scores for massive and non-massive RCRs (p=0.35 and p=0.45 respectively). No revision surgery was required within the minimum one year follow up timescale.

Arthroscopic massive rotator cuff repairs have no functional difference to non-massive rotator cuff repairs in the short term follow up period and should be considered in appropriate patient groups.

Introduction. Currently, a validate scale of ankle osteoarthritis (OA) is not available and different classifications have been used, making comparisons between studies difficult. In other joints as the hip and knee, the Kellgren-Lawrence (K&L) scale, chosen as reference by the World Health Organizations is widely used to characterize OA. It consists of a physician based assessment of 3 radiological features: osteophyte formation, joint space narrowing and bone end sclerosis described as follows: grade 0: normal joint; grade 1: minute osteophytes of doubtfull significance; grade 2: definite osteophytes; grade 3: moderate diminution of joint space; grade 4: joint space greatly impaired, subchondral sclerosis. Until now, the K&L scale has never been validated in the ankle. Our objective was to assess the usefulness of the K&L scale for the ankle joint, by determining its reliability and by comparing it to functional scores and to computerized minimal joint space width (minJSW) and sclerosis measurements. Additionally we propose an atlas of standardized radiographs for each of the K&L grades in the ankle. Methods. 73 patients 10 to 20 years post ankle ORIF were examined. Bilateral ankle radiographs were taken. Four physicians independently assessed the K&L grades and evaluated tibial and talar sclerosis on anteroposterior radiographs. Functional outcome was assessed with the AOFAS Hindfoot score. Bone density and minJSW were measured using a previously validated Ankle Image Digital Analysis software (AIDA). Results. The interobserver reliability, for the K&L stages was 0.60 (intraclass correlation coefficient) indicating moderate to good agreement. The mean AOFAS hindfoot score decreased substantially (p = 009) and linearly from 99.3 in K&L grade 0 to 79.5 points in K&L grade 4. The minJSW assessed by AIDA was similar among grades 0 to 2 (between 2 and 2.5mm), but significantly lower in grade 3 (1.8mm) and in grade 4 (1.1mm). A decreased minJSW less than 2mm, commonly used as a threshold for the assessment of hip and knee OA, was found in 77% of K&L grades 3–4 compared to 33% of grades 0–2, sensitivity 77.4% and specificity 66.7%. Physician based assessment revealed that subchondral sclerosis was present in 16% of K&L grade 1 patients, 52% of grade 2, 70% of grade 3 and 100% of grade 4 patients. No correlation could be found between physician based assessment and digital image analysis of subchondral sclerosis. Conclusions. Interobserver reliability in assessment of ankle OA using the K&L scale was similar to other previously described joints. OA progression correlated with functional diminution. Joint space narrowing assessed AIDA as well as the cut-off of 2mm correlated well with the K&L scale. Overall, we recommend the use of the K&L scale for the radiographic assessment of ankle OA

The use of pulsed electromagnetic fields (PEMF) to stimulate bone growth has been recommended as an alternative to the surgical treatment of ununited scaphoid fractures, but has never been examined in acute fractures. We hypothesised that the use of PEMF in acute scaphoid fractures would accelerate the time to union by 30% in a randomised, double-blind, placebo-controlled, multicentre trial. A total of 53 patients in three different medical centres with a unilateral undisplaced acute scaphoid fracture were randomly assigned to receive either treatment with PEMF (n = 24) or a placebo (n = 29). The clinical and radiological outcomes were assessed at four, six, nine, 12, 24 and 52 weeks. A log-rank analysis showed that neither time to clinical and radiological union nor the functional outcome differed significantly between the groups. The clinical assessment of union indicated that at six weeks tenderness in the anatomic snuffbox (p = 0.03) as well as tenderness on longitudinal compression of the scaphoid (p = 0.008) differed significantly in favour of the placebo group. We conclude that stimulation of bone growth by PEMF has no additional value in the conservative treatment of acute scaphoid fractures

Aims

To compare operative and nonoperative treatment for displaced distal radius fractures in patients aged over 65 years.
