Tibial pilon fractures are typically the result of high-energy axial loads, with complex intra- articular fractures that are often difficult to reconstruct anatomically. Only nine simultaneous pilon and talus fractures have been published previously, but we hypothesised the chondral surface of the dome is affected more frequently. Data was acquired prospectively from 154 acute distal tibial pilon fractures (AO/OTA 43B/C) in adults. Radiographs, photographs, and intra-operative drawings of each case were utilised to document the presence of any macroscopic injuries of the talus. Detailed 1x1mm maps were created of the injuries in each case and transposed onto a statistical shape model of a talus; this enables the cumulative data to be analysed in Excel. Data was analysed using a Chi-squared test. From 154 cases, 104 were considered at risk and their talar domes were inspected; of these, macroscopic injuries were identified in 55 (52.4%). The prevalence of talar dome injury was greater with B-type fractures (53.5%) than C-type fractures (31.5%) (ρ = .01). Injuries were more common in men than women and presented with different distribution of injuries (ρ = .032). A significant difference in the distribution of injuries was also identified when comparing falls and motor vehicle accidents (ρ = .007). Concomitant injuries to the articular surface of the dome of the talus are relatively common, and this perhaps explains the discordance between the post-operative appearance following internal fixation and the clinical outcomes observed. These injuries were focused on the lateral third of the dome in men and MVAs, whereas women and fall mechanism were more evenly distributed. Surgeons who operatively manage high-energy pilon fractures should consider routine inspection of the talar dome to assess the possibility of associated macroscopic osteochondral injuries

Surfing has rapidly grown in popularity as the sport made its debut at the Tokyo 2020 Olympic Games. Surfing injuries are becoming more relevant with the globalisation and increasing risks of the sport, but despite this, little is known about surfing injuries or prevention strategies in either the competitive or recreational surfer. We reviewed the literature for the incidence, anatomical distribution, type and underlying mechanism of acute and overuse injuries, and discuss current preventative measures. Four online databases, including MEDLINE, PubMed, EMBASE and Cochrane Library were searched from inception to March 2020. This review finds that skin injuries represent the highest proportion of total injuries. Acute injuries most frequently affect the head, neck and face, followed by the lower limbs. Being struck by one's own board is the most common mechanism of injury. Surfers are injured at a frequency of 0.30–6.60 injuries per 1000 hours of surfing. Most prior studies are limited by small sample sizes, poor data collection methodology and geographical constraints. The scientific literature on surfing injuries under-represents overuse musculoskeletal injuries and the efficacy of prevention strategies for surfing-related overuse musculoskeletal injuries has not been studied. Injuries to the head and neck pose greater risks to a surfer's morbidity and mortality, yet there is no consensus on the management protocol of spinal injuries that occur in open water. Non-contact acute ligament injuries have increased as surfing manoeuvres have become more acrobatic, and overuse musculoskeletal injuries are highly correlated with paddling. Further research is needed to establish preventative measures for both acute and overuse surfing injuries and to ensure the increasing popularity of surfing is met with an improved understanding of sport risks and safety. Specifically, we recommend research be prioritised regarding the efficacy of training programmes to prevent surfing-related overuse musculoskeletal injuries

Traumatic rotator cuff injuries can be a leading cause of prolonged shoulder pain and disability, and contribute to significant morbidity and healthcare costs. Previous studies have shown evidence of socio-demographic disparities with these injuries. The purpose of this nationwide study was to better understand these disparities based on ethnicity, sex, and socio-economic status, in order to inform future healthcare strategies. Accident Compensation Corporation (ACC) is a no-fault comprehensive compensation scheme encompassing all of Aotearoa/New Zealand (population in 2018, 4.7 million). Using the ACC database, traumatic rotator cuff injuries were identified between January 2010 and December 2018. Injuries were categorized by sex, ethnicity, age and socioeconomic deprivation index of the claimant. During the 9-year study period, there were 351,554 claims accepted for traumatic rotator cuff injury, which totalled over $960 million New Zealand Dollars. The greatest proportion of costs was spent on vocational support (49.8%), then surgery (26.3%), rehabilitation (13.1%), radiology (8.1%), general practitioner (1.6%) and “Other” (1.1%). Asian, Māori (Indigenous New Zealanders), and Pacific peoples were under-represented in the age-standardized proportion of total claims and had lower rates of surgery than Europeans. Māori had higher proportion of costs spent on vocational support and lower proportions spent on radiology, rehabilitation and surgery than Europeans. Males had higher number and costs of claims and were more likely to have surgery than females. There were considerably fewer claims from areas of high socio-economic deprivation. This large nation-wide study demonstrates the important and growing economic burden of rotator cuff injuries. Indirect costs, such as vocational supports, are a major contributor to the cost suggesting improving treatment and rehabilitation protocols would have the greatest economic impact. This study has also identified socio-demographic disparities which need to be addressed in order to achieve equity in health outcomes

Introduction:. During the Christmas period a number of patients are admitted to the Chris Hani Baragwanath Academic Hospital (CHBAH) Hand Unit with explosive injuries to their hands caused by firecrackers. South African legislation restricts the sale and use of fireworks to adults, with a limitation being placed on the size of explosive and type of commercial outlet. Despite this an inordinate amount of explosive hand injuries are admitted over the festive season. Aim:. To evaluate the epidemiological pattern of firecracker injuries to the hand during the Christmas festive period and assess contributing factors. Comparison to a previous study in 2008 will also be evaluated. Method:. Patients with firecracker injuries to the hand were interviewed. Demographic information, events surrounding the incident including alcohol use, and origin of the explosive were recorded. Injuries were classified into minor, moderate and severe based on the amount of soft tissue and bony damage. Treatment and complications was recorded. The data is also compared to previous data obtained in 2008. Results:. 26 patients were admitted. 2 patients were injured with explosives from a legal source. Alcohol use was implicated in 10 of the injuries. 17 amputations were performed at various levels, 9 fractures and 2 dislocations were stabilised with K-wires. Sepsis was more common in severe injuries. The majority of patients were injured from mis-use with several patients suffering injuries following removal of explosives from children or from other people throwing explosives at them or their family. These results are similar to those obtained in 2008. Conclusion:. A large number of patients are injured by firecrackers during the festive period. Injuries are severe. Lack of law enforcement, alcohol and misuse are contributing factors in these injuries. No significant change has occurred in the pattern of injury between 2008 and 2011

Sledging related minor and major injuries represent a significant workload at ski-area medical centers across the world. Although safety rules exist, they are seldom obeyed or enforced. We set out to determine the incidence of sledging related injuries, identifying trends and causative factors at a busy New Zealand Ski resort. All sledging related injuries presenting during a 70-day period were prospectively reviewed. Patient demographics, mechanism, diagnosis, and treatment were recorded. Sixty patients were identified, mean age 10 years, range 4-30 years. Injuries comprised; collisions with sledgers (21), collision with wall (14) and falling from sledge (14). Site of injury included head (36), lower limb (18), spine (9), upper limb (7), and abdomen (2). Fractures included; femur (1), tibia (1), fibula (1), ankle (2), cuboid (1), clavicle (2), scaphoid (1). One 9-year-old patient sustained a serious intracranial haemorrhage, with subsequent permanent neurological sequelae. Sledging related injuries are mostly minor, however significant major injuries do occur requiring intervention at a secondary center. The potential for serious morbidity is evident. Recommendations supporting safety improvement measures does exist, however most were not implemented by the study cohort examined. The use of basic cycling helmets would seem an appropriate minimum level of protection, and greater sledging safety awareness should be encouraged

Tendon injuries after distal radius fractures Introduction: Tendon injuries after distal radius fractures are a well-documented complication that can occur in fractures managed both operatively and non-operatively. The extensor tendons, in particular the extensor pollicis longus (EPL) tendon, can be damaged and present late after initial management in a cast, or by long prominent screws that penetrate the dorsal cortex and cause attrition. Similarly, a prominent or distally placed volar plate can damage the flexor pollicis longus tendon (FPL). The aim of our study was to evaluate the incidence of tendon injuries associated with distal radius fractures.

We conducted a single centre prospective observational study. Patients aged 18–99 who presented with a distal radius fracture between May 2018 to April 2020 were enrolled and followed-up for 24 months. Tendon injuries in the group were prospectively evaluated. Results: 199 patients with distal radius fractures were enrolled. 119 fractures (59.8%) had fixation and 80 (40.2%) were managed incast. In the non-operative group, 2 (2.5%) had EPL ruptures at approximately 4 weeks post injury. There were no extensor tendon ruptures in the operative group. In the operative group, there were 6 (5%) patients that required removal of metalware for FPL irritation. At the time of operation, there were no tendon ruptures noted. Within the operative group we evaluated plate prominence using a previously described classification (Soong et al.). 5 of the 6 patients (83%) with FPL irritation had Grade 3 prominence.

The incidence of both flexor and extensor tendon injury in our cohort was 4%, extensor tendon rupture was 1% and flexor tendon rupture was avoided by early metalware removal. This study demonstrates tendon injuries are not uncommon after distal radius fractures, and close examination and follow-up are necessary to prevent eventual rupture. Plate prominence at the time of fixation should be minimised to reduce the risk of rupture.

Severe spinal injuries in rugby are rare – but the consequences are considerable. This study presents a series of severe or catastrophic spinal injuries involving under-18 Scottish rugby players since 1992. Demographic and medical data were collected from records at the Queen Elizabeth National Spinal Injuries Unit for Scotland. The players were interviewed personally by the main author, using a questionnaire developed to expose risk factors contributing to injury. All patients were male rugby union players, aged from 14-17. Twelve severe or catastrophic spinal injuries occurred between 1992 and 2009; 10/12 resulted in neurological dysfunction. Six players were forwards and 6 were backs. Three injuries occurred during scrums and 9 injuries resulted from tackles. Five players were injured during league games, 5 during ‘friendly’ games and 1 during a trial game for a regional team. All reported the playing conditions as good and 67% occurred in the second half of the game. The rate of spinal injury was 1 every 3 years from 1992 to 2007. In the last 3 years of the study (2007 to 2010) 7 spinal injuries occurred (including 6 with neurological compromise). 6/12 players thought there was a mismatch between the teams, 3/12 were playing their first game for that team, 2/12 players changed position during the match and 3/12 players were playing above their age group. Overall, one of these four risk factors was present in 10/12 (82%) of cases. 7/12 players felt their injury was preventable. This study demonstrates that the rate of severe spinal injuries in Scottish under-18 rugby had increased to an unacceptable level. Since these data were shared with the Scottish Rugby Union, safety measures have been implemented in an effort to reduce the rate of injuries in youth rugby

Background:. Injuries inflicted by gunshot wounds (GSW) are an immense financial burden on the South African healthcare system. The cost of treating an abdominal GSW has previously been estimated at R30 000 per patient. No study has been conducted to estimate the financial burden from an orthopaedic perspective. Objective:. To estimate the average cost of treating GSW victims requiring orthopedic interventions in a South African tertiary level hospital. Methods:. The study surveyed over 1,500 orthopedic admissions to our institution during 2012 to indentify GSW patients. A folder review yielded data on theatre time, implant cost, duration of admission, diagnostic-imaging studies performed, blood products used, laboratory costs and medicines issued to analyze costs. Results:. A total of 111 patients with an average age of 28 years (range 13–74) were identified. Each patient was hit by an average of 1.69 bullets (range 1–7). One hundred and forty seven fractures were sustained. Ninety-five patients received surgical treatment for a total of 128 orthopedic procedures, 15 concurrent general/vascular surgery procedures, and a cumulative surgical time of 198 hours 42 minutes. Cumulative anaesthetic time was 277 hours 33 minutes. Theatre costs (excluding implants) were estimated to be in excess of ten million rands. Ninety three of the patients received an implant during surgery which raised theatre costs even more. Total costs were in excess of R130 000.00 forward admissions, R180 000.00 for imaging, R190 000.00 for blood products, R16 000.00 for laboratory investigations and R16 000.00 for discharge medication. Conclusion:. Using varying calculations it was estimated that on average an orthopaedic GSW patient costs about R100 000.00 to treat, utilises about 2 hours of theatre time per operation and occupies a bed for an average period of 9 days

Introduction and aims. We present a series of patients who have had secondary reconstruction of war injuries to the upper and lower limbs, sustained during the Iraq and Afghanistan conflicts. Material and Methods. All patients were seen at the combined Peripheral Nerve Injuries Clinic at the Defence Medical Centre for Rehabilitation, Headley Court. All surgery was performed at Odstock Hospital. Procedures include scar excision and neurolysis (all patients), release of scar contractures, tenolysis, tendon transfers, revision nerve grafts, excision of neuroma, and soft tissue reconstruction using pedicled or free flaps. Results. 24 patients have been treated at the time of submission. We have used 13 free flaps (1 free groin flap, 9 anterolateral thigh, 3 parascapular, with 4 as through-flow flaps) and 1 pedicled groin flap, with no flap losses. There were 6 amputation stump revisions (1 above elbow, 5 below knee). The majority (n=23) have had nerve recovery distal to the level of injury following revision surgery. Conclusions. Nerve repairs recover following neurolysis (and revision nerve graft if necessary) with provision of good soft tissue cover. Release of scar contractures with flap cover allows healing of chronic wounds and permits mobilisation of joints. Thin fascio-cutaneous flaps provide good contour and can be elevated more easily than skin grafted muscle flaps for secondary surgery. Free or regional flaps are preferable to local flaps in high energy-transfer military wounds. Immediate complex reconstruction is not always appropriate in multiply-injured patients

Poor availability of allografts in South Africa has led to an increased use of synthetic augmentation to stabilize knee joints in the treatment of knee dislocations. This study aims to evaluate multiligament knee injuries treated with a posterior cruciate ligament internal brace.

The study included patients with knee dislocations who were treated with a PCL internal brace. The internal brace involved the insertion of a synthetic suture tape, which was drilled into the femoral and tibial footprint. Chronic injuries were excluded. Patient-reported outcome scores (PROMs), range of motion, stress X-Rays, and MRI scans were reviewed to assess outcomes. Acceptable outcomes were defined as a Lysholm score of 84 or more, with grade II laxity in no more than one ligament and a range of motion from full extension to 90° or more.

The study included eight patients, with a median age of 42, of which five were female. None of the patients had knee flexion less than 90° or an extension deficit of more than 20°. PROMs indicated acceptable outcomes (EQ5D, Tegner Lysholm). Stress radiographs showed less than 7mm (Grade I) of posterior translation laxity in all patients. Four patients underwent MRI scans 1–2 years after the initial surgery, which revealed healing of the PCL in all patients. However, increased signal in a continuous ligament suggested only partial healing in two patients. Tunnel widening of 200% and 250% was noted around the tibial and femoral PCL footprints, respectively.

All patients demonstrated stable knees and acceptable PROMs. Tunnel widening was observed in all patients who had MRI scans. Factors such as suspensory fixation, anisometric tunnel position, and the absence of PCL tear repair may have contributed to the tunnel widening.

Intimate partner violence (IPV) causes significant morbidity and its unlikely to be reported compared to other forms of gender-based violence (GBV). For early detection, understanding Orthopaedic injuries from GBV is vital. This study assesses the pattern of musculoskeletal injuries from GBV and determines the factors associated with it.

It is a retrospective observational study of patients aged ≥18 years, with GBV-related acute Orthopaedic injuries. Data was reviewed from January 2021 to December 2021, including, demographic information, soft tissue and bony injuries, relationship to assailant, substance abuse and the day and time of injury. Frequencies and percentages for categorical data were analysed. Chi-square test was used to calculate association. T-test was used to compare groups for continuous & categorical variables. Multivariate analysis was conducted to find the odds ratio and a p-value <0.05 was statistically significant.

138 patients were included, the mean age at presentation being 35.02 years (SD=11). 92.75% of GBV victims were females. Most were unemployed (66.7%). 30.43% (n-42) had a soft tissue injury; superficial laceration being the most common (23.1%), flexor tendon injury (10.87%), hand abscess (5.8%), and extensor tendon injury (5.07%). 71.02 % (n=98) sustained appendicular fractures. 51.45% (n=71) sustained upper limb fractures; distal radius fractures (10.86%) and distal 3rd ulnar fractures (9,42%). 19.57% (n=27) had lower limb fractures; 7.25% (n=10) had lateral malleolus ankle fractures. 63.7% (n=80) of cases were by an intimate partner on weekends (50.73%). 62.31% occurred between 16h00 and 0h00. 41.1% (n=65) reported alcohol abuse. 63.04% had surgery.

GBV likely occurs in early middle-aged females by intimate partners influenced by alcohol over the weekends between 16h00 to 0h00. Distal radius/distal 3rd ulnar fractures are the most common bony injuries. Superficial wrist laceration is the commonest soft tissue injury. These findings may assist with early detection and intervention to prevent adverse outcomes in GBV.

We retrospectively reviewed the hospital records of 68 patients diagnosed with posterolateral corner (PLC) knee injuries by a specialist knee consultant in two hospitals over the period from 2005 to 2009. Injuries were diagnosed based on a combination of findings from clinical testing together with results of imaging and arthroscopic findings. Over 75% of patients presented within 24 hours of their injury with an average presentation at 8 days post-injury. 92% of patients complained subjectively of instability. We found PLC injuries were most often combined with ACL injury and secondarily with PCL injury and only 12% were isolated lesions of the PLC. The most common mechanism of injury was a non contact twisting injury (52%) confirming the importance of recognising that often no direct contact occurs in PLC injured knees. The average delay to diagnosis was 30 months from time of injury. Over 70% of the injuries were not identified at the time of initial presentation, with the PLC injury only recognised in those patients who had severe multi-ligament injuries. At the time of referral to the specialist knee clinics only 50% of patients had correctly been given a diagnosis that included injury of the PLC. Magnetic resonance imaging (MRI) correctly identified 93% of the PLC injuries when performed acutely (within 12 weeks of the initial injury) but only in 27% of patients whose scan was performed over 12 weeks following injury. We conclude that the diagnosis of PLC injury appears to be frequently missed apart from cases where severe multiple ligament injury has occurred. Clinical history and thorough examination with a high index of suspicion are key in avoiding misdiagnosis of PLC injury. MRI scans accurately identify PLC injury in the acute phase (within 12 weeks of injury) but may be of limited use following this time period

We analysed the morbidity, mortality and outcome of cervical spine injuries in patients over the age of 65 years in a retrospective review of 107 elderly patients admitted to our tertiary referral spinal injuries unit with cervical spine injuries between 1994 and 2002. The data were acquired by analysis of the national spinal unit database, hospital inpatient enquiry (HIPE) system, chart and radiographic review. Mean age was 74 years (range 66-93yrs). The male to female ratio was 2.1: 1(M=72, F=35). The mean follow-up was 4.4 years (1-9 years) and mean in-hospital stay was 10 days. The mechanism of injury was a fall in 75 and a road traffic accident (RTA) in the remaining 32 patients. The overall complication rate was 18.6% with an associated in-hospital mortality of 11.2%. Outcome was assessed using the Cervical Spine Outcomes Questionnaire (CSOQ) from Johns Hopkins School of Medicine. Functional outcome scores approached pre-morbid level in almost all patients. Functional disability was more marked in the patients with neurological deficit at the time of injury. Outcome of the injury is related to the increasing age, co-morbidity and the severity of the neurological deficit. Injuries of the cervical spine are a not infrequent occurrence in the elderly and occur with relatively minor trauma. Neck pain in the elderly patient should be thoroughly evaluated to exclude C2 injuries. Most patients can be managed in an orthosis but unstable injuries require rigid external immobilisation

The Royal Marines regularly deploy to Norway to conduct Cold Weather, Arctic and Mountain Warfare training. A total of 1200 personnel deployed to Norway in 2010 over a 14-week period. Patients, whose injuries prevented them from continuing training, were returned to the UK via AEROMED. The aim of this investigation was to describe the epidemiology of musculoskeletal injuries during cold weather training. All data on personnel returned to the UK was prospectively collected and basic epidemiology recorded. 53 patients (incidence 44/1,000 personnel) were returned to the UK via AEROMED. 20/53 (38%) of cases were musculoskeletal injuries (incidence 17/1000 personnel). 15/20 musculoskeletal injuries were sustained while conducting ski training (incidence 13/1,000): 4/20 were non-alcohol related injuries, 1/20 was related to alcohol consumption off duty. Injuries sustained whilst skiing: 5/15 sustained anterior shoulders dislocation, 5/15 Grade 1-3 MCL/LCL tears, 2/15 sustained ACJ injuries, 1/15 crush fracture T11/T12, 1/15 tibial plateau fracture and 1/15 significant ankle sprain. Non-Training injuries: 1 anterior shoulder dislocation, 1 distal radial fracture, 1 olecranon fracture, 1 Scaphoid Fracture and one 5th metatarsal fracture. 60% of injuries were upper limb injuries. The most common injury was anterior shoulder dislocation 6/20 (Incidence 5/1000). Our results suggest that cold weather warfare training has a high injury rate requiring evacuation: 4% of all people deployed will require AEROMED evacuation, and 2% have musculoskeletal injuries. Ski training causes the majority of injuries, possibly due to the rapid transition from non-skier to skiing with a bergen and weapon. Military Orthopaedic and rehabilitation units supporting the Royal Marines, should expect sudden increases in referrals when large scale cold weather warfare training is being conducted. Further research is required to see if musculoskeletal injury rates can be decreased in cold weather warfare training

Removal of bullets retained within joints is indicated to prevent mechanical blockade, 3rd body wear and resultant arthritis, plus lead arthropathy and systemic lead poisoning. The literature is sparse on this subject, with mostly sporadic case reports utilizing hip arthroscopy. We report on the largest series of removal of bullets from the hip joints using open surgical.

We reviewed prospectively collected data of patients who presented to a single institution with civilian gunshot injuries that breached the hip joint between 01 January 2009 and 31 December 2022.

We included all cases where the bullet was retained within the hip joint area. Exclusion criteria: cases where the hip joint was not breached, bullets were not retained around the hip area or cases with isolated acetabulum involvement.

One hundred and eighteen (118) patients were identified. One patient was excluded as the bullet embedded in the femur neck was sustained 10 years earlier. Of the remaining 117 patients, 70 had retained bullets around the hip joint. In 44 patients we undertook bullet removal using the followingsurgical hip dislocation (n = 18), hip arthrotomy (n = 18), removal at site of fracture fixation/replacement (n = 2), posterior wall osteotomy (n = 1), direct removal without capsulotomy (tractotomy) (n = 5).

In 26 patients we did not remove bullets for the following reasons: final location was extra-capsular embedded in the soft tissues (n=17), clinical decision to not remove (n=4), patients’ clinical condition did not allow for further surgery (n= 4) and patient refusal (n=1). No patients underwent hip arthroscopy.

With adequate pre-operative imaging and surgical planning, safe surgical removal of retained bullets in the hip joint can be achieved without the use of hip arthroscopy; using the traditional open surgical approaches of arthrotomy, tractotomy and surgical hip dislocation.

Abstract

This study investigated concurrent talar dome injuries associated with tibial pilon fractures, mapping their distribution across the proximal talar dome articular surface. It compared the two main mechanisms of injury (MOI), falling from a height and motor vehicle accident (MVA), and whether the fractures were open or closed.

From a previously compiled database of acute distal tibial pilon fractures (AO/OTA 43B/C) in adults of 105 cases, 53 cases were identified with a concurrent injury to the talar dome with a known mechanism of injury and in 44 it was known if the fracture was open or closed. Case specific 2D injury maps were created using a 1x1mm grid, which were overlayed in an Excel document to allow for comparative analyses. A two-way ANOVA was conducted that examined the effect of both MOI and if the fracture was open or closed on what percentage of the talar dome surface was injured.

There was a statistically-significant difference between the average percentage of injured squares on the talar dome by both whether the fracture was open or closed (f(1)=5.27, p= .027) and the mechanism of injury (f(1)=8.08, p= .007), though the interaction between these was not significant (p= .156). Open injuries and injuries that occurred during an MVA were more likely to increase the surface area of the talar dome injuries.

We have identified both MOI and if the fracture was either open or closed impacts the size of the injury present on the talar dome. Future research will investigate the aetiology of the differences noted, highlighting the clinical implications.

Surgeons treating tibial pilon fractures caused by either a MVA or an open fracture, should be aware of an increased risk of large injuries to the surface of the talar dome.

Lisfranc injuries account for 0.2% of all fractures and have been linked to poorer functional outcomes, in particular resulting in post-traumatic arthritis, midfoot collapse and chronic pain. This study assesses the longitudinal functional outcomes in patients with low and high energy Lisfranc injuries treated both operatively and non-operatively.

Patients above 16 years with Lisfranc injuries from January 2008 and December 2017 were identified through the Victorian Orthopaedic Trauma Outcomes (VOTOR) registry. Follow-up performed at 6, 12 and 24 months through telephone interviews with response rate of 86.1%, 84.2% and 76.2% respectively. Longitudinal functional outcome data using Global Outcome Assessment, EQ-5D-5L, numerical pain scale, Short-Form 12, the WHO Disability Assessment Schedule and return to work status were collected. Univariate analysis was performed and variables showing a significant difference between groups (p < 0.25) were analysed with multivariable mixed effects regression model.

745 patients included in this retrospective cohort study. At 24 months, both the operative and non-operative groups demonstrated similar functional outcomes trending towards an improvement. Mixed effect regression models for the EQ items for mobility (OR 1.80, CI 0.91 – 3.57), self-care (OR 1.95, 95% CI 1.09-3.49), usual activities (OR 1.10, 95% CI 0.99-1.03), pain (OR 1.07, 95% CI 0.61-1.89), anxiety (OR 1.29, 95% CI 0.72-2.34) and pain scale (OR 1.07, 95% CI 0.51 – 2.22) and return to work (OR 1.28, 95% CI 0.56-2.91) between groups were very similar and not statistically significantly different.

We concluded that there was no statistically significant difference between operative and non-operative patients with low and high energy Lisfranc injuries. Current clinical practices in Lisfranc injury management are appropriate and not inadvertently causing any further harm to patients. Future research comparing fracture patterns, fixation types and corresponding functional outcomes can help determine gold standard Lisfranc injury management.

There has been a substantial increase in the surgical treatment of unstable chest wall injuries recently. While a variety of fixation methods exist, most surgeons have used plate and screw fixation. Rib-specific locking plate systems are available, however evidence supporting their use over less-expensive, conventional plate systems (such as pelvic reconstruction plates) is lacking. We sought to address this by comparing outcomes between locking plates and non-locking plates in a cohort of patients from a prior randomized trial who received surgical stabilization of their unstable chest wall injury.

We used data from the surgical group of a previous multi-centred, prospective, randomized controlled trial comparing surgical fixation of acute, unstable chest wall injuries to non-operative management. In this substudy, our primary outcome was hardware-related complications and re-operation. Secondary outcomes included ventilator free days (VFDs) in the first 28 days following injury, length of ICU and hospital stay, and general health outcomes (SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores). Categorical variables are reported as frequency counts and percentages and the two groups were compared using Fisher's Exact test. Continuous data are reported as median and interquartile range and the two groups were compared using the Wilcoxon rank-sum test.

From the original cohort of 207 patients, 108 had been treated surgically and had data available on the type of plate construct used. Fifty-nine patients (55%) had received fixation with non-locking plates (primarily 3.5 or 2.7 mm pelvic reconstruction plates) and 49 (45%) had received fixation with locking plates (primarily rib-specific locking plates). The two groups were similar in regard to baseline and injury characteristics. In the non-locking group, 15% of patients (9/59) had evidence of hardware loosening versus 4% (2/49 patients) in the locking group (p = 0.1). The rate of re-operation for hardware complications was 3% in the non-locking group versus 0% in the locking group (p = 0.5). No patients in either group required revision fixation for loss of reduction or nonunion. There were no differences between the groups with regard to VFDs (26.3 [19.6 – 28] vs. 27.3 [18.3 – 28], p = 0.83), length of ICU stay (6.5 [2.0 – 13.1] vs 4.1 [0 – 11], p = 0.12), length of hospital stay (17 [10 – 32] vs. 17 [10 – 24], p = 0.94) or SF-36 PCS (40.9 [33.6 – 51.0] vs 43.4 [34.1 – 49.6], p = 0.93) or MCS scores (47.8 [36.9 – 57.9] vs 46.9 [40.5 – 57.4], p = 0.95).

We found no statistically significant differences in outcomes between patients who received surgical stabilization of their unstable chest wall injury when comparing non-locking plates versus locking plates. However, the rate of hardware loosening was nearly 4 times higher in the non-locking plate group and trended towards statistical significance, although re-operation related to this was less frequent. This finding is not surprising, given the inherent challenges of rib fixation including thin bones, comminution, potential osteopenia and a post-operative environment of constant motion. We believe that the increased cost of locking plate fixation in this setting is likely justifiable given these findings.

Our study sought to establish the necessity of prolonged pre-operative antibiotic prophylaxis in patients presenting with zone II and zone V acute flexor tendon injuries (FTI). We hypothesized that a single dose of prophylactic antibiotic was adequate in prevention of post-operative wound infection in acute zone II and V FTI.

This was a prospective study of 116 patients who presented with zone II and zone V acute FTI. The study included patients who were 18 years and older. Those with macroscopic contamination, immunocompromised, open fractures, bite injuries, and crush injuries were excluded. Patients were randomised into a group receiving a single dose of prophylactic antibiotic and another group receiving a continuous 8 hourly antibiotic doses until the day of surgery. Each group was subdivided into occupational and non-occupational injuries. Their post-operative wound outcomes were documented 10 – 14 days after surgery. The wound outcome was reported as no infection, superficial infection (treated with wound dressings), and deep infection (requiring surgical debridement).

There was 0.9% rate of deep post-operative wound infections, which was a single zone V acute FTI case in a single dose prophylactic antibiotic group. There was a 7.8% superficial post-operative wound infection rate, which was mainly zone II acute FTI in both antibiotic groups. There was a strong association between zone II acute FTI and post-operative wound infection (p < 0.05). There was no association between (antibiotic dosage or place of injury) with post-operative wound infection (p > 0.05).

There is no benefit in prescribing prolonged pre-operative antibiotic in patients with acute, simple lacerations to zone II and zone V FTI if there is no macroscopic wound contamination.
