Background Distinguishing stable from unstable ankle fractures is key to successful ankle fracture management. Gravitational stress views (GSV) may be a convenient and less painful alternative to manual stress testing. The aim of this study was to assess whether this test accurately predicts ankle instability. Methods Patients presenting to a single trauma centre between 2011 and 2013 with an isolated fibula fracture and a an anatomically-aligned mortise on initial plain film radiographs were reviewed. After initial x-ray, patients underwent a gravity stress view. Measurements from plain film radiographs were recorded and analysed. Electronic case notes and National Imaging Archives were reviewed retrospectively at a minimum of 10 years post-injury. Patients were contacted to complete patient reported outcome measures (PROMS). Results One-hundred and forty-two (142) patients met the inclusion criteria and were included in the study. Mean initial film medial clear space (MCS) measurement was 3.46mm (1.0 to 6.0) compared to GSV MCS that was 4.9mm (2.0 to 8.8) (p<0.001). No patient underwent surgery and all patients had successful conservative management with anatomical union seen at their 6 week radiograph. No patient returned with a complication related to their ankle fracture during the follow-up period. With a MCS acquired from GSV of >5mm, 65 patients would have undergone unnecessary surgical intervention. At MCS of >6mm, 26 patients would have undergone surgery unnecessarily and at a MCS of >7mm 10 patients would have had unnecessary surgery. To date, 50 patients have provided PROMs. Mean Olerud and Molander Score (OMAS) at 10 years was 86.63 (SD 23.27, 95% CI 79.47 – 93.79), Manchester Oxford Foot Questionnaire (MOXFQ) was 79.41 (SD 32.94, 95% CI 69.39 – 89.42) and Euroqol-5D-3L was 0.86 (SD0.22, 95% CI 0.79 – 0.93). Conclusion Stress views may over-diagnose instability in patients with an isolated fibula fracture in an otherwise normal initial radiograph.

Background Studies have compared open reduction internal fixation (ORIF) with fibular nail fixation (FNF) and shown reduced wound complications with minimal difference to PROMS in the short term. Our aim is to compare long-term outcomes for unstable ankle fractures at 10 year follow up. Methods Patients from a previously conducted RCT were contacted at a minimum of 10 years post intervention at a single study centre. Case notes were reviewed, and patient reported outcome measures acquired at 10 years. Results Ninety-nine patients were included (48 FNF and 51 ORIF). After 10 years 75% (33/44) of patients in the FNF group required no further follow up versus 81% (39/48) in the ORIF group. Radiographically at 2 years post-injury, there was no statistically significant difference between groups for development of osteoarthritis (p=0.851). There was one tibio-talar fusion in each group secondary to osteoarthritis, but no statistically significant difference in overall re-operation rate (p=0.518). Fifty-one percent (n=50) of patients have so far returned patient reported outcome measures at a minimum of 10 years (Fibular nail n=23, plate fixation n=27). No significant difference was found between groups for the mean scores of Olerud and Molander Ankle Score (FNF 84.78 vs ORIF 84.07; p=0.883), the Manchester-Oxford Foot Questionnaire (MOXFQ) (FNF 89.54 vs ORIF 96.47; p=0.112), Euroqol-5D Index (FNF 0.88 vs ORIF 0.87; p=0.701) and Euroqol-5D Visual Analogue Score (FNF 77.30 vs ORIF 77.52; p=0.859). Conclusion The current study illustrates that both methods of treatment result in a satisfactory long-term outcome with no difference in late complications or PROM scores at up to 10 years in patients under 65 years old, although the study is currently under powered.

To compare the long-term outcomes of fibular nailing and plate fixation for unstable ankle fractures in a cohort of patients under the age of 65 years. Patients from a previously conducted randomized control trial comparing fibular nailing and plate fixation were contacted at a minimum of 10 years post intervention at a single study centre. Short term data were collected prospectively and long-term data were collected retrospectively using an electronic patient record software. Ninety-nine patients from one trauma centre were included (48 fibular nails and 51 plate fixations). Groups were matched for gender ( p = 0.579), age ( p = 0.811), body mass index (BMI)( p = 0.925), smoking status ( p = 0.209), alcohol status ( p = 0.679) and injury type ( p = 0.674). Radiographically at an average of 2 years post-injury, there was no statistically significant difference between groups for development of osteoarthritis ( p = 0.851). Both groups had 1 tibio-talar fusion (2% of both groups) secondary to osteoarthritis with no statistically significant difference in overall re-operation rate between groups identified ( p = 0.518,). Forty-five percent (n=42) of patients had so far returned patient reported outcome measures at a minimum of 10 years (Fibular nail n=19, plate fixation n=23). No significant difference was found between groups at 10 years for the Olerud and Molander Ankle Score ( p = 0.990), the Manchester-Oxford Foot Questionnaire ( p = 0.288), Euroqol-5D Index ( p = 0.828) and Euroqol-5D Visual Analogue Score ( p = 0.769). The current study illustrates no difference between fibular nail fixation and plate fixation at a long-term follow up of 10 years in patients under 65 years old, although the study is currently under powered.

Objective: To compare the outcome of fibular nailing with plate fixation for unstable fractures of the ankle in a cohort of patients under the age of 65 years. Setting: 2 international university trauma centers. Patients/Participants: One hundred twenty-five patients who were 18–64 years of age with an acute unstable fracture of the ankle were included in the study. Intervention: Patients were randomized to fixation with a fibular nail (n = 63) or plate (n = 62) and were reviewed at 6 weeks, 3 months, 6 months, 1 year, and 2 years after surgery. Main Outcome Measurements: The primary outcome measure was the Olerud and Molander score at 1 year. Secondary outcomes were the rates of complications and reinterventions. Results: There was no difference between the 2 groups with respect to the primary outcome measure [mean Olerud and Molander score 78.4 in the nail group vs. 80.2 in the plate group ( P = 0.621)]. Wound infections occurred in 2 patients who were treated with a nail and 9 patients who were treated with a plate, but this did not reach statistical significance. No difference was seen in the overall rate of complications and reinterventions between groups [28.6% in the nail group vs. 29% in the plate group ( P = 0.955)]. Conclusions: In younger patients with ankle fractures, no difference was found in the patient-reported outcome between fibular nail and plate fixation at 1 year after surgery. The fibular nail is an effective and safe option for the stabilization of ankle fractures in younger patients, although the benefits associated with reduced wound complications are not as apparent as for elderly patients.

AIMS:The migration percentage (MP) is one criterion used for surgery in dislocated or displaced hips in children with cerebral palsy (CP). The MP at which a displaced hip can no longer return to normal is unclear. The aim of this paper was to identify the point of no return of the MP through a large population-based study.METHODS:All children registered on the Cerebral Palsy Integrated Pathway Scotland surveillance programme undergo regular pelvic radiographs. Any child who had a MP measuring over 35% since the programme's inception in 2013, in at least one hip and at one timepoint, was identified. The national radiography database was then interrogated to identify all pelvic radiographs for each of these children from birth through to the date of analysis. A minimum of a further two available radiographs following the initial measurement of MP ≥ 35% was required for inclusion.RESULTS:A total of 239 children (346 hips) were identified as suitable for analysis at a mean of 6.5 years (2.0 to 14.8) follow-up. In all, 1,485 radiographs taken both prior to and after a hip had a MP ≥ 35% were examined and the MP measured to identify any progression of displacement. Interrogation of the data identified that hips with a MP up to 46% returned to a MP below 40% without intervention, and all hips with a MP equal to or greater than 46% displaced further and the MP did not return to the normal range. Statistical analysis showed the result to be 98% specific with this degree of certainty that hips reaching a MP ≥ 46% would not spontaneously regress.CONCLUSION:These findings are clinically relevant in showing that it may be reasonable to continue to monitor hips with a MP not exceeding 46%. This threshold will also guide referral for further management of a displacing hip. Cite this article: Bone Joint J 2021;103-B(2):411-414.

PURPOSE:The purpose of this study is to report the number of children from a total population of children with cerebral palsy (CP) in Scotland who had a displaced or dislocated hip at first registration in a national surveillance programme.METHODS:Migration percentage (MP), laterality, Gross Motor Function Classification System (GMFCS) level, CP subtype, distribution of CP and age were analyzed in 1171 children. Relative risk was calculated with 95% confidence intervals. Hip displacement and dislocation were defined as a MP of 40 to 99 and > 100 respectively.RESULTS:Radiographs were available from the first assessment of 1171 children out of 1933 children registered on the system. In all, 2.5% of children had either one or both hips dislocated (29/1171) and dislocation only occurred in children of GMFCS levels IV and V. A total of 10% of children had a MP 40 to 99 in one or both hips (117/1171). An increasing GMFCS level was strongly associated with an abnormal MP. Hip dislocation was unusual in patients under the age of seven years. A MP of 40 to 99 was not seen in children with isolated dystonia. Displacement was more frequent in children with bilateral involvement and dislocation was only seen in spastic and mixed tone groups.CONCLUSION:This data gives an overview of the number of CP children who have hip displacement/dislocation in Scotland and who will possibly require surgery.LEVEL OF EVIDENCE:I.

Techniques for fixation of fractures of the lateral malleolus have remained essentially unchanged since the 1960s, but are associated with complication rates of up to 30%. The fibular nail is an alternative method of fixation requiring a minimal incision and tissue dissection, and has the potential to reduce the incidence of complications. We reviewed the results of 105 patients with unstable fractures of the ankle that were fixed between 2002 and 2010 using the Acumed fibular nail. The mean age of the patients was 64.8 years (22 to 95), and 80 (76%) had significant systemic medical comorbidities. Various different configurations of locking screw were assessed over the study period as experience was gained with the device. Nailing without the use of locking screws gave satisfactory stability in only 66% of cases (4 of 6). Initial locking screw constructs rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable. Overall, seven patients had loss of fixation of the fracture and there were five post-operative wound infections related to the distal fibula. This lead to the development of the current technique with a screw across the syndesmosis in addition to a distal locking screw. In 21 patients treated with this technique there have been no significant complications and only one superficial wound infection. Good fracture reduction was achieved in all of these patients. The mean physical component Short-Form 12, Olerud and Molander score, and American Academy of Orthopaedic Surgeons Foot and Ankle outcome scores at a mean of six years post-injury were 46 (28 to 61), 65 (35 to 100) and 83 (52 to 99), respectively. There have been no cases of fibular nonunion. Nailing of the fibula using our current technique gives good radiological and functional outcomes with minimal complications, and should be considered in the management of patients with an unstable ankle fracture.

Objectives: To identify risk factors for fixation failure, report patient outcomes, and advise on modifications to the surgical technique for fibula nail stabilization of unstable ankle fractures. Design: Retrospective review. Setting: Academic orthopaedic trauma unit. Patients: All 342 patients were identified retrospectively from a prospectively collected single-center trauma database over a 9-year period. Intervention: Unstable ankle fractures managed surgically with a fibula nail. Main Outcome Measurements: The primary short-term outcome was failure, defined as any case that required revision surgery because of an inadequate mechanical construct. The mid-term outcomes included the Olerud–Molander Ankle Score and the Manchester–Oxford Foot Questionnaire. Results: Twenty failures occurred (6%), of which 7 (2%) were due to device failure and 13 (4%) due to surgeon error. Of the surgeon errors, 8 consisted of inappropriate weight-bearing after syndesmotic diastasis, and 5 were due to inadequate fracture reduction or poor nail placement. Proximal locking screw (PLS) pull-out was the cause of all device failures. Positioning the PLS >20 mm above the plafond significantly increased failure risk (P = 0.003). At a mean follow-up of 5.1 years (range, 8 months–8 years) the median Olerud–Molander Ankle Score and Manchester–Oxford Foot Questionnaire were 80 (interquartile range, 45) and 10.94 (interquartile range, 44.00), respectively. Patient outcome was not negatively affected by the requirement for revision surgery. Conclusions: The fibula nail offers secure fixation and good patient-reported outcomes for unstable ankle fractures. Appropriate postoperative management and surgical technique, including careful placement of the PLS, is essential to minimize construct failure risk. Level of Evidence: Therapeutic Level IV.

Assessment of stability in ankle fractures is key in deciding the most appropriate mode of treatment. Stress radiographs have been suggested as a potential method for assessing ankle stability in patients with apparently isolated lateral malleolar fractures. Whilst stress radiographs have been found to be both sensitive and specific in cadaveric experiments, recent clinical studies have suggested that a widened medial clear space (MCS) on stress radiographs may not equate to a functionally unstable ankle. We aimed to assess whether patients with an apparently isolated lateral malleolar fracture on presentation but with a positive gravity stress radiograph (GSR) could be successfully managed non-operatively.A prospective study of all patients with lateral malleolar fractures presenting to our orthopaedic trauma department was undertaken. Patients with an oblique distal fibular fracture pattern and no obvious MCS widening on routine radiographs underwent a GSR. Measurements of the radiographic MCS and super...

Lateral malleolar plating is associated with complication rates of up to 30%. The fibular nail is an alternative fixation technique, requiring a minimal incision and tissue dissection, with the potential to reduce the incidence of complications. We reviewed our results of 105 unstable ankle fractures fixed with the Acumed fibular nail between 2002 and 2010. The mean age was 65 years and 72% of patients had significant systemic medical comorbidities.A number of different locking screw configurations were assessed over the study period. A proximal blocking screw resulted in satisfactory stability in 93%, single locking screws in 86%, but nailing without locking in only 66%, leading to the development of our current technique. Of the twenty-one patients treated with this technique there have been no significant complications, and only two superficial wound infections. Good fracture reduction was achieved in all of these patients. The mean physical component SF12, Olerud and Molander and Foot and Ankle Outcom...

Open reduction and internal fixation (ORIF) of ankle fractures is associated with well known complications including wound dehiscence and infection, construct failure and symptomatic metalwork. A technique of intramedullary fibular nailing has been developed that requires only minimal incisions, is biomechanically stronger than ORIF and has low-profile hardware. We hypothesized that fibular nailing would result in a rate of reduction and union comparable to ORIF, with a reduced rate of wound and hardware problems.100 patients over the age of 65 years with unstable ankle fractures requiring fixation were randomised to undergo fibular nailing or ORIF. Outcome measures assessed over the 12 postoperative months were wound complications, accuracy of reduction, Olerud and Molander score (OMS), and total cost of treatment.The mean age was 74 years (range 65–93) and 75 patients were women, all had some form of comorbidity. Significantly fewer wound infections occurred in the fibular nail group (p=0.002). Eight pa...

BACKGROUND AND AIMS:Cerebral palsy is the commonest long-term physical disability in children with a prevalence of between 1.77 and 2.11/1000 live births. In 2013, the Cerebral Palsy Integrated Pathway Scotland (CPIPS) surveillance programme was introduced in all 14 Health Boards in Scotland and provides a standardised musculoskeletal examination of the spine and lower limbs. The purpose of this study was to report the prevalence, subtypes, motor classification and motor ability of children with cerebral palsy in Scotland.METHODS AND RESULTS:The family/carer's postal address, the child's neurological classification, motor subtypes, Gross Motor Functional Classification (GMFCS) Level and Functional Mobility Scale of 1972 children at first registration in CPIPS 2013-2018 were analysed. Their mean age at first assessment was 7.6 years. There was an overall prevalence of cerebral palsy in Scotland of 2.02/1000. GMFCS levels and Functional Mobility Scale data and prevalence were reported by Health Board and were comparable to that reported elsewhere.CONCLUSION:For the first time, data are available on the motor abilities of the total population of children with cerebral palsy in Scotland. This information will be highly relevant to resource management of current and future motor needs of these children.

We have previously reported that fibular nailing in the elderly is associated with a significantly reduced complication rate and greater cost-effectiveness when compared to ORIF. The aim of this st...

PurposeTo assess outcomes of manipulating upper extremity fractures with conscious sedation compared with formal reduction and casting in theatre under general anaesthesia and image intensifier control.MethodProspective six month period all patients presenting to the Emergency Department with a both bone forearm or distal radial fracture that was deemed suitable for closed reduction and casting where included in the study. All fractures deemed to require instrumentation were excluded.ResultsWe identified 56 fractures, 13 of the distal radius and 43 both bone forearm. 22 where treated in theatre with 34 treated in ED. Age range 2–14 years. We had 1 re fracture in the ED group and 1 re fracture in the theatre group. All fractures united within acceptable limits. We had no re operations in either group. No complications from the procedural sedation or anaesthesia. Mean time to treatment in theatre group was 18 hours Vs 3 hours in the ED group (P< 0.05).ConclusionThe use of procedural sedation, closed reducti...

Early weight-bearing of patients with ankle fractures is associated with good outcomes. There are a number of potential advantages to early mobilisation including reduced hospital stay and earlier return to work and regular daily activities. However, many surgeons have not incorporated this into their routine ankle fracture protocol, particularly for patients managed operatively; potentially due to concerns regarding loss of reduction. We hypothesised that ankle fractures managed fully weight-bearing would have good outcomes and a low rate of loss of reduction.All ankle fractures presenting to our department over a 15-month period were studied prospectively. Patients were instructed to mobilise fully weight-bearing as able, either immediately postoperatively (for those fractures considered unstable that underwent operative intervention), or at the first fracture clinic review (if stable and managed conservatively). Only patients with syndesmotic injuries and those with neuropathy or psychiatric illness we...

The aim of this study was to document both the short and long term outcome of isolated displaced olecranon fractures treated with primary non-operative intervention. We identified from our prospective trauma database all patients who were managed non-operatively for a displaced olecranon fracture over a 13-year period. Inclusion criteria included all isolated fractures of the olecranon with >2 mm displacement of the articular surface. Demographic data, fracture classification, management, complications and subsequent surgeries were recorded. The primary short-term outcome measure was the Broberg and Morrey Elbow score. The primary long-term outcome measure was the DASH score.There were 43 patients in the study cohort with a mean age of 76 yrs (40–98). A low energy fall from standing height accounted for 84% of all injuries, with ≥1 co-morbidities documented in 38 (88%) patients. At a mean of 4 months (range, 1.5–10) following injury the mean Broberg and Morrey score was 83 (48–100), with 72% achieving an ...

There are concerns regarding the rates and significance of DVT and PE following ankle fracture with published rates of VTEs varying widely. This study aimed to identify the incidence of VTEs in patients with ankle fractures and to compare this to the background risk of VTEs in these patients and the population. 1,283 consecutive patients with ankle fractures presenting to our trauma centre over a twenty-month period were studied prospectively. Patients with conservatively-managed ankle fractures were encouraged to mobilise weight-bearing but not provided with chemical thromboprophylaxis, whilst operatively-managed fractures were only prescribed chemical thromboprophylaxis during their inpatient stay. Both hospital and national episode data were searched to identify VTEs between 1981 and 2014. Over this 33-year period there were 17 PEs and 5 DVTs. Of these, 50percnt; occurred prior to the ankle fracture, 23percnt; greater than one year after the fracture and only 27percnt; in the 90 days following injury, ...

Aims Patients with diabetes are at increased risk of wound complications after open reduction and internal fixation of unstable ankle fractures. A fibular nail avoids large surgical incisions and allows anatomical reduction of the mortise. Patients and Methods We retrospectively reviewed the results of fluoroscopy-guided reduction and percutaneous fibular nail fixation for unstable Weber type B or C fractures in 24 adult patients with type 1 or type 2 diabetes. The re-operation rate for wound dehiscence or other indications such as amputation, mortality and functional outcomes was determined. Results Two patients developed lateral side wound infection, one of whom underwent wound debridement. Three other patients required re-operation for removal of symptomatic hardware. No patient required a below-knee amputation. Six patients died during the study period for unrelated reasons. At a median follow-up of 12 months (7 to 38) the mean Short Form-36 Mental Component Score and Physical Component Score were 53.2 (95% confidence intervals (CI) 48.1 to 58.4) and 39.3 (95% CI 32.1 to 46.4), respectively. The mean Visual Analogue Score for pain was 3.1 (95% 1.4 to 4.9). The mean Ankle Osteoarthritis Scale total score was 32.9 (95% CI 16.0 to 49.7). Conclusion Fluoroscopy-guided reduction and fibular nail fixation of unstable ankle fractures in patients with diabetes was associated with a low incidence of wound and overall complications, while providing effective surgical fixation.
