Aims

The aims of this study were to identify means to quantify coronal plane displacement associated with distal radius fractures (DRFs), and to understand their relationship to radial inclination (RI).

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

The aim of this study was to document our experience of acute forearm compartment syndrome, and to determine the risk factors for requiring split skin grafting (SSG) and developing complications post fasciotomy. We identified from our trauma database all patients who underwent fasciotomy for an acute forearm compartment syndrome over a 22-year period. Diagnosis was made using clinical signs and/or compartment pressure monitoring. Demographic data, aetiology, management, wound closure, complications and subsequent surgeries were recorded. Outcome measures were the use of SSG and the development of complications following forearm fasciotomy. 90 patients were identified with a mean age of 33 yrs (range, 13–81 yrs) and a significant male predominance (n=82, p<0.001). A fracture of one or both of the forearm bones was seen in 62 (69%) patients, with soft tissue injuries causative in 28 (31%). The median time to fasciotomy was 12hrs (2–72). Delayed wound closure was achieved in 38 (42%) patients, with 52 (58%) undergoing SSG. Risk factors for requiring a SSG were younger age and a crush injury (both p<0.05). Complications occurred in 29 (32%) patients at mean follow-up of 11 (3–60) months. Risk factors for developing complications were a delay in fasciotomy of >6 hrs (p=0.018), with pre-operative motor symptoms approaching significance (p=0.068). Forearm compartment syndrome requiring fasciotomy predominantly affects males and can occur following either a fracture or soft tissue injury. Age is an important predictor of undergoing SSG for wound closure. Complications occur in a third of patients and are associated with an increasing delay in the time to fasciotomy

Aims. The aim of this study was to statistically analyse the incidence and distribution of forearm fractures in the adult age group (3rd–10th Decades) between 1997 and 2009. Methods. Records of patients with forearm fractures were retrieved from the hospital audit department using the predetermined codes to identify patients. The data included total number of patients between 20 and 100 years who were either reviewed in the fracture clinics or admitted to the hospital with forearm fractures along with patient gender, age at the time of incident and time of the year the incident occurred. Incidence of total fractures per year and per each month in the year was calculated. The patients were divided into age groups between 2nd to 10th decades. Linear regression analysis was carried out to identify the relationship between fracture incidence and the age or time of the injury. Correlation coefficients(R) and r2 were calculated for all the regression analyses. Fractures were also classified according to the Orthopaedic Trauma Association (OTA) classification system. SPSS (version 16) and Microsoft Excel 2007 were used for statistics. Results. A total of 1815 fractures were identified that included 573 males and 1242 females (F/M=2.17). The average age of patients was 59.8 years. Comparing the different months of the year for fracture incidence, the incidence of fractures was found to be highest in september per year. There was a linear increase in the incidence of fractures from January to September (R=0.9, r2=0.81) followed by a drop in subsequent months. There was a linear increase in the incidence of fractures per year from 70 in 1997 to 200 in 2009 (R=0.94, r2=0.885). Comparing the slopes of linear equations for males and females, the rate of increase in fractures in females was found to be approximately 3 times that of males. In women, There was a linear increase in the fracture incidence from the 3rd decade to the 9th decade (R=0.91, r2=0.84) followed by a sudden drop in the 10th decade. In men, there was a linear decrease in the fracture incidence from the 3rd to the 9th decade (r2=0.9559, R=0.98). 177 fractures were classified according to the OTA classification. OTA 23 type of fractures accounted for 85.3% percent of the forearm fractures followed by OTA 21 type (11.9%) and 22 type (2.8%). Further analysis showed the distribution to be: 23A-43.7%, 23B-9.9%, 23C-46.4%. Conclusion. In the last 13 years, there has been an increase in the total incidence of forearm fractures in both men and women; however, the rate of increase in women is almost 3 times that of men. With increasing age, the incidence of fracture increases in women and decreases in men. The drop in fractures in women the 10th decade can be attributed to a reduced living population after 90 years. The obtained linear equations can be useful in predicting the number of forearm fractures occurring in a certain age group in community

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

Pain produced by the tourniquet is a common source of complaint for patients undergoing carpal tunnel decompression. Practice varies as to tourniquet position. There is little evidence to suggest benefit of one position over another. Our aim was to compare the experience of both the patient and the surgeon with the tourniquet placed either on the arm or the forearm. Ethical approval was granted. Following power calculation and a significance level set at 0.05, 100 patients undergoing open carpal tunnel decompression under local anaesthetic were randomised to arm or forearm group. Visual Analogue Scores (VAS) (0–100) for pain, blood pressure and heart rate were taken at 2 minute intervals. The operating surgeon provided a VAS for bloodless field achieved and obstruction caused by the tourniquet. The demographics of the groups was similar. There were no statistically significant differences in any measure between the groups. Average tourniquet times were 8.8 minutes (forearm) and 8.2 minutes (arm). The average VAS score for forearm and arm was 13 and 11 respectively for bloodless field, 9 and 2 for obstruction. Average overall VAS for pain was 27 in each group, however interval VAS scores for pain were higher in the arm group. The average change Mean Arterial Pressure was −5 mmHg (forearm) −2 mmHg (arm) pulse rate was −1 bpm (forearm) and −2 bpm (arm). Tourniquet placement on the arm does not result in significant difference in patient pain, physiological response or length of operation. Surgeons reported less obstruction and better bloodless fields with an arm tourniquet, however there was a trend for forearm tourniquet to result in less pain for the patient

There is a high rate of forearm deformity in patients with hereditary multiple exostoses (HME), and a quarter of patients acquire a dislocated radial head due to disproportionate ulnar shortening. One-hundred and six patients with HME aged 15 years or older were identified from a prospective database. Flexion and extension of the elbow and wrist, and supination and pronation of the forearm was measured. The number of exostoses affecting the proximal and distal radius and ulna were recorded. Proportional ulna length was calculated as a percentage of the patients measured height ([ulna length/height] × 100). More than 70% of patients were affected by exostoses of the forearm, of which the distal radius was the commonest site to be affected (73%). One in seven patients had a dislocated radial head, which was associated with proportional ulna shortening (p<0.001). Both radial head dislocation (p<0.001) and proportional ulna shortening (p<0.001) were confirmed to be independent predictors of forearm motion on multivariable regression analysis. In conjunction with other predictors these could be used to calculate ROM of the forearm. In addition proportional ulna length was also an independent predictor of radial head dislocation (p<0.001). Proportional ulna length could be used as a tool to identify patients at risk of diminished forearm motion and radial head dislocation during childhood, who could be monitored clinically and radiographically, and surgical intervention could be offered before deterioration in function and dislocation of the radial head occurs

Displaced fractures of the forearm in children are often treated conservatively, but there is a relatively high incidence of redisplacement, malunion and consequent limitation of function. We have performed percutaneous Kirschner (K) wire fixation in 72 such children under the age of 14 years, of which 57 were reviewed for our study. Both the radius and ulna were fractured in 45 (79%), the radius only in eight and the ulna only in four. The mean initial angulation was 19° in the lateral plane and 9° in the anteroposterior plane for the radius and 15° and 9°, respectively, for the ulna. In 42 patients (74%) we performed closed reduction. In the remaining 15 (26%) closed reduction failed and an open reduction, through a minimal approach, was required before K wiring. At a mean follow-up of 20 months all patients had good functional results with an excellent range of movement. Only five had angulation of from 10° to 15° and none had nonunion, premature epiphyseal closure or deep infection. Percutaneous intramedullary K wiring for forearm diaphyseal fracture is a convenient, effective and safe operation, with minimal complications

At-home softcast removal with no routine clinical follow-up has shown to be safe and effective following paediatric orthopaedic trauma. It minimises clinician contact time and reduces cost. However, there is limited data on the caregiver experience. Retrospective analysis of paediatric fractures requiring application of circumferential softcast that was later removed at home. Two time points were included: (1)July–September 2022, (2)February–April 2023. Demographics data included age, fracture classification, angulation, manipulation requirement, complications or unplanned re-attendance. Caregivers were given an information leaflet on cast removal. Caregivers completed a telephone Likert questionnaire reviewing time taken to remove cast, qualitative descriptors of cast removal and overall satisfaction. 77 families were contacted at mean 93 days post injury. Mean age was 7.5 years. 41(53%) were distal radius and 20(26%) both-bone forearm fractures. The remaining were hand, elbow or tibia injuries. 40(52%) injuries required manipulation under procedural sedation with mean sagittal angulation 24 degrees. 13(17%) patients re-attended with cast problems. Caregivers estimated a mean 13 minutes to remove cast. 83% found it ‘extremely’ or ‘somewhat’ easy. 75% were ‘extremely’ or ‘somewhat’ satisfied. 71% were ‘extremely’ or ‘somewhat’ likely to recommend at-home cast removal. Qualitative descriptors ranged from from ‘traumatising’ to ‘fun’ and ‘straightforward’. The experience at our tertiary centre confirms at-home softcast removal with no further orthopaedic follow-up is safe and feasible, even in those requiring manipulation under sedation. The majority of families reported a positive experience; this however is not universal. Adequate patient information resources are integral to a positive caregiver's experiences

The Pronator Quadratus (PQ) is commonly damaged in the surgical approach to the distal radius during volar plating. This study explored the functional strength of the PQ muscle, 12 months after volar plating of a distal radial fracture. Testing of treated and contralateral forearms was carried out using a custom-made Torque Measuring Device (TMD) and surface Electromyography (sEMG). To assess both the direct and indirect function of PQ in participants treated with volar plating and compared to the contralateral non-injured forearms. The angle of elbow flexion was varied from 45o, 90o and 135o when measuring forearm pronation. Mean peak torque of the major pronating muscles, PQ and Pronator Teres (PT) was directly measured with the TMD and the indirect activation of the PQ and PT was measured with sEMG. In total 27 participants were studied. A statistically significant reduction in mean peak pronation torque was observed in the volar plated forearms (P<0.05 SE 0.015, CI 95%). This is unlikely to be of clinical significance as the mean reduction was small (13.43Nm treated v 13.48Nm none treated). Pairwise comparison found no statistically significant reduction in peak torque between 45o, 90o and 135o of elbow flexion. There was an increase in PQ muscle activation at 135o compared to 45o elbow flexion. The converse was identified in PT. The small but statistically significant difference in mean peak torque in treated and uninjured forearms is unlikely to be of clinical significance and results suggest adequate functional recovery of the PQ after volar plating

Most fractures of the radial head are stable undisplaced or minimally displaced partial fractures without an associated fracture of the elbow or forearm or ligament injury, where stiffness following non-operative management is the primary concern. Displaced unstable fractures of the radial head are usually associated with other fractures or ligament injuries, and restoration of radiocapitellar contact by reconstruction or prosthetic replacement of the fractured head is necessary to prevent subluxation or dislocation of the elbow and forearm. In fractures with three or fewer fragments (two articular fragments and the neck) and little or no metaphyseal comminution, open reduction and internal fixation may give good results. However, fragmented unstable fractures of the radial head are prone to early failure of fixation and nonunion when fixed. Excision of the radial head is associated with good long-term results, but in patients with instability of the elbow or forearm, prosthetic replacement is preferred. This review considers the characteristics of stable and unstable fractures of the radial head, as well as discussing the debatable aspects of management, in light of the current best evidence.

Dynamometric measurement of the grasp strength is commonly used in wrist assessment. On the other hand measurement of the pronation-supination (PS) strength has been few studied. The longitudinal forearm rotation needs integrity of the two radioulnar joints and of the antebrachial interosseous membrane. The strength developed during PS assesses also trophicity of pronator and supinator muscles. A PS dynamometer (Baseline ®, AREX) is now available for such measurements. The aims of this study were: 1) to study the best way to neutralize the shoulder movements of abduction-adduction, 2) to find the values of PS Strength in a healthy population, and 3) to study correlations between this PS force and several biometric items. A first series of measurements des PS strength was performed thanks to the Baseline dynamometer in 8 people, in association with two devices neutralizing the shoulder movements of abduction-adduction, in repeated campaigns allowed the authors to determine and keep the better one for optimal measurements following campaigns. To assess the normal values of PS Strength in a healthy population, 38 healthy volunteers from both genders and different ages, classified according their age class, from three different forearm position: neutral, from 90 ° of supination and 90 ° of pronation. Finally, statistical analysis looked for correlations between PS strength and some biometric data. Manipulations beginning from a neutral position of forearm were the most reliable. The mean strength within the whole studied sample (76 wrists, 17 male, 21 female) was 10.6 N.m (standard deviation SD 3.26) for the supination and 13.9 N.m (standard deviation 4.19) for the supination. The dominant side exhibited a PS strength superior by 7.5% to that of the non-dominant side. Male gender, the height and weight of the body, forearm circumference displayed positive relationships with PS strength. Mean values of PS strength, measured from a neutral forearm rotation and with the best device to neutralize the shoulder movements, in a healthy population of 38 volunteers, allowed the authors establishing reference values. They will allow precise comparisons between the values found in patients suffering from forearm and/or wrist pathology and the healthy population, taking into account the age, gender and hand dominance

A series of 26 children was referred to our specialist unit with a ‘pink pulseless hand’ following a supracondylar fracture of the distal humerus after a mean period of three months (4 days to 12 months) except for one referred after almost three years. They were followed up for a mean of 15.5 years (4 to 26). The neurovascular injuries and resulting impairment in function and salvage procedures were recorded. The mean age at presentation was 8.6 years (2 to 12). There were eight girls and 18 boys. Only four of the 26 patients had undergone immediate surgical exploration before referral and three of these four had a satisfactory outcome. In one child the brachial artery had been explored unsuccessfully at 48 hours. As a result 23 of the 26 children presented with established ischaemic contracture of the forearm and hand. Two responded to conservative stretching. In the remaining 21 the antecubital fossa was explored. The aim of surgery was to try to improve the function of the hand and forearm, to assess nerve, vessel and muscle damage, to relieve entrapment and to minimise future disturbance of growth. Based on our results we recommend urgent exploration of the vessels and nerves in a child with a ‘pink pulseless hand’, not relieved by reduction of a supracondylar fracture of the distal humerus and presenting with persistent and increasing pain suggestive of a deepening nerve lesion and critical ischaemia

The Essex-Lopresti injury is rare. It consists of fracture of the head of the radius, rupture of the interosseous membrane and disruption of the distal radioulnar joint. The injury is often missed because attention is directed towards the fracture of the head of the radius. We present a series of 12 patients with a mean age of 44.9 years (26 to 54), 11 of whom were treated surgically at a mean of 4.6 months (1 to 16) after injury and the other after 18 years. They were followed up for a mean of 29.2 months (2 to 69). Ten patients had additional injuries to the forearm or wrist, which made diagnosis more difficult. Replacement of the head of the radius was carried out in ten patients and the Sauve-Kapandji procedure in three. Patients were assessed using standard outcome scores. The mean post-operative Disabilities of the Arm, Shoulder and Hand score was 55 (37 to 83), the mean Morrey Elbow Performance score was 72.2 (39 to 92) and the mean Mayo wrist score was 61.3 (35 to 80). The mean grip strength was 68.5% (39.6% to 91.3%) of the unaffected wrist. Most of the patients (10 of 12) were satisfied with their operation and in 11 the pain was relieved. When treating the chronic Essex-Lopresti injury, we recommend accurate realignment of the radius and ulna and replacement of the head of the radius. If this fails a Sauve-Kapandji procedure to arthrodese the distal radioulnar joint should be undertaken to stabilise the forearm while maintaining mobility

Aims

The aim of the present study was to assess the outcomes of the induced membrane technique (IMT) for the management of infected segmental bone defects, and to analyze predictive factors associated with unfavourable outcomes.

This study compares the outcomes of two methods of fixation of displaced fractures of the radial neck. The 58 patients with a mean age of 38.5 years (18 to 56), were treated in a non randomised study with screws (n = 29) or a plate and screws (n = 29) according to the surgeon’s preference. The patients were reviewed at one year. Radiographs and functional evaluations were carried out up to one year post-operatively, using the Broberg and Morrey functional evaluation score, range of movement, and assessment of complications. The mean functional scores did not differ significantly between groups (90 (55 to 100) vs 84; 50 to 100, p = 0.09), but the mean range of forearm rotation in screw group was significantly better than in the plate group (152°; 110° to 170° vs 134°; 80° to 170°, p = 0.001). Although not statistically significant, the screw group had a lower incidence of heterotopic ossification than the plate group (n = 1) than the plated group (n = 3) and the pathology was graded as less severe.

Aims

In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED. We investigated whether this altered care pathway leads to a reduction in healthcare consumption and concomitant costs.

Aims

This is a multicentre, prospective assessment of a proportion of the overall orthopaedic trauma caseload of the UK. It investigates theatre capacity, cancellations, and time to surgery in a group of hospitals that is representative of the wider population. It identifies barriers to effective practice and will inform system improvements.

Aims

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

In severe forearm injuries, the diagnosis of disruption of the interosseous membrane is frequently delayed and sometimes missed, giving difficulties in the salvage of forearm stability. We studied the structure and function of the interosseous membrane in 11 cadaver preparations, using mechanical and histological analysis. Seven of the specimens tested in uniaxial tension sustained a mid-substance tear of the central band of the membrane at a mean peak load of 1038 ± 308 N. The axial stiffness was 190 ± 44 N/mm with elongation to failure of 10.34 ± 2.46 mm. These results provide criteria for the evaluation of reconstructive methods. A preliminary clinical investigation of the use of ultrasound suggests that this may be of value in the screening of patients with complex fractures of the forearm, and for investigating the natural history of tears of the interosseous membrane
