Our unit has pursued a policy of using donor nerves from the same limb for grafting. Nerves which have already been affected by the primary injury are selected where possible, thus avoiding any new sensory deficit. 36 of the 41 brachial plexus repairs were available for outcome data collected prospectively over 2 years. Over a nine year period, donor nerves used for the 41 brachial plexus repairs included the lateral cutaneous nerve of the forearm, superficial radial, medial cutaneous of the forearm, ulnar and sural nerves. Patients were grouped into having injured nerve grafts only (A), injured and uninjured nerve grafts (B) and uninjured nerve grafts. The repaired brachial plexus nerves were assessed by measuring the MRC grading of the power of movement of the muscle innervated by that nerve (i.e. elbow flexion for musculocutaneous nerve). These were graded as good (MRC grading 3 or better), fair (MRC grade 1 or 2), or poor (MRC 0). The greatest success for nerve grafting was elbow flexion with good results in 22 out of 27 assessments. Using Mann-Whitney test, Group A had significantly better results (p=0.025) than group C. However, ignoring the poorer results of shoulder abduction there was no significant difference between all 3 groups of patients. We conclude that using injured nerve grafts taken distal to the lesion in the brachial plexus is as effective as using nerve material from an uninjured limb

The suprascapular nerve is an ideal target for nerve blockade to alleviate shoulder pain given its widespread innervation to the shoulder girdle. Many techniques have been described. To widen the availability of this treatment we investigate whether an anatomical landmark technique can be easily learned by novice injectors to provide efficacious blockade. Five injectors were recruited with varying experience; from the novice medical student to an orthopaedic consultant. Five torsos (10 shoulders) were used. A single page of written instruction and illustration of the Dangoisse landmark technique was provided prior to injection of a Thiel embalmed cadaver bilaterally. A pre-mixed injectate with blue dye was used. Cadavers were dissected and the presence or absence of dye staining reported by 3 observers and a consensus agreement reached. Dissection demonstrated diffuse staining in the suprascapular fossa. 90% of shoulders were found to have adequate staining of the suprascapular nerve directly, or its distal branches, in a manner which would provide adequate anaesthesia. The inter-observer agreement was good (k = 0.73) for staining at the supraspinous fossa and excellent (k=0.87) for staining distally. The technique was easily performed by novice injectors with a 100% success rate. We demonstrate that this technique is reproducible by a range of clinicians to effectively provide anaesthesia of the SScN. The main risks are ineffective block (10% in this series) and of intravascular injection. Within a resource strained healthcare environment greater uptake of this technique is likely to be of benefit to a wider array of patients

Introduction. Nerve conduction studies are considered to be the investigation of choice for the diagnosis of Carpal Tunnel Syndrome. However they are expensive and can be painful. We scored patients based on a ten point scoring system; four symptoms (Katz Hand Diagram – Classic and Probable pattern for tingling and numbness, nocturnal paresthesia, bilateral symptoms), four signs (weak thumb abduction test, Tinel sign, Phalen sign, Hypoalgesia in median nerve territory) and two risk factors (age more than 40 years and female sex). This was done in an effort to predict the severity of carpal tunnel syndrome and to correlate it with nerve conduction studies. Method. A prospective study of 59 patients was performed between May 2009 and March 2010. For every patient in the study we completed a scoring system based on ten points and correlated it with the severity (normal, mild, moderate and severe) result from the nerve conduction studies. Results. There were 61 completed data sets (59 patients, two patients had bilateral carpal tunnel release). The mean age of patients was 60 years (range: 37–91 years). The mean duration of symptoms was 17 months. The female to male ratio was 2.3:1. All scores greater than seven matched with nerve conduction study of moderate to severe intensity apart from three scores which were greater than seven that matched with a normal result. Conclusion. Based on this study, we believe that patients who score less than eight may require nerve conduction studies to confirm the diagnosis of carpal tunnel syndrome. However patients who score more than seven have a 93% chance of having moderate to severe carpal tunnel syndrome on nerve conduction studies

Aims. We aimed to identify the pattern of nerve injury associated with paediatric supracondylar fractures of the humerus. Patients and Methods. Over a 17 year period, between 1996 and 2012, 166 children were referred to our specialist peripheral nerve injury unit. From examination of the medical records and radiographs were recorded the nature of the fracture, associated vascular and neurological injury, treatment provided and clinical course. Results. Of the 166 patients (111 male, 55 female; mean age at time of injury was seven years (standard deviation 2.2)), 26 (15.7%) had neurological dysfunction in two or more nerves. The injury pattern in the 196 affected nerves showed that the most commonly affected nerve was the ulnar nerve (43.4%), followed by the median (36.7%) and radial (19.9%) nerves. A non-degenerative injury was seen in 27.5%, whilst 67.9% were degenerative in nature. Surgical exploration of the nerves was undertaken in 94 (56.6%) children. The mean follow-up time was 12.8 months and 156 (94%) patients had an excellent or good clinical outcome according to the grading of Birch, Bonney and Parry. Conclusion. Following paediatric supracondylar fractures we recommend prompt referral to a specialist unit in the presence of complete nerve palsy, a positive Tinel’s sign, neuropathic pain or vascular compromise, for consideration of nerve exploration. . Take home message: When managed appropriately, nerve recovery and clinical outcomes for this paediatric population are extremely favourable. Cite this article: Bone Joint J 2016;98-B:851–6

Brachial plexus tumours (BPT) and peripheral nerve sheath tumours (PNST) are largely benign in nature, with malignant tumours being rare and presenting significant surgical challenges. Excision of benign tumours may relieve pain and other symptomology. This retrospective study analysed data from 138 PNST and 92 BPT patients managed by a single consultant orthopaedic or plastic surgeon experienced in nerve tumour surgery between January 1999 to December 2019. The most common benign tumours were schwannomas and neurofibromas, with sarcomas being the most common malignant tumour. In the PNST group 30 patients were managed by observation only. Twenty patients underwent trucut biopsy, 21 patients underwent biopsy and surgical excision and 56 patients underwent surgical excision only. There were nine complications, with two significant neurological deficits requiring further surgical intervention. No recurrence of tumours occurred in this group. In the BPT group 16 patients were managed by observation only. Seven patients underwent trucut biopsy, 16 patients biopsy and surgical excision and 44 BPT patients underwent surgical excision only. Sixteen patients had complications with two significant complications requiring urgent further surgical intervention. Seven patients had recurrence of tumours which presented as metastases, with three patients requiring further surgery to remove recurrence of tumours. BPT patients are more complex and present with both benign and malignant lesions and are therefore more prone to complications due to the complex nature of the surgery and higher recurrence rate of tumours than PNST. Benign tumours in both groups can be safely managed conservatively if patients’ symptomology is acceptable

We describe 261 peripheral nerve injuries sustained in war by 100 consecutive service men and women injured in Iraq and Afghanistan. Their mean age was 26.5 years (18.1 to 42.6), the median interval between injury and first review was 4.2 months (mean 8.4 months (0.36 to 48.49)) and median follow-up was 28.4 months (mean 20.5 months (1.3 to 64.2)). The nerve lesions were predominantly focal prolonged conduction block/neurapraxia in 116 (45%), axonotmesis in 92 (35%) and neurotmesis in 53 (20%) and were evenly distributed between the upper and the lower limbs. Explosions accounted for 164 (63%): 213 (82%) nerve injuries were associated with open wounds. Two or more main nerves were injured in 70 patients. The ulnar, common peroneal and tibial nerves were most commonly injured. In 69 patients there was a vascular injury, fracture, or both at the level of the nerve lesion. Major tissue loss was present in 50 patients: amputation of at least one limb was needed in 18. A total of 36 patients continued in severe neuropathic pain. This paper outlines the methods used in the assessment of these injuries and provides information about the depth and distribution of the nerve lesions, their associated injuries and neuropathic pain syndromes

Between 1998 and 2002, 37 neuropathies in 32 patients with a displaced supracondylar fracture of the humerus who were referred to a nerve injury unit were identified. There were 19 boys and 13 girls with a mean age of 7.9 years (3.6 to 11.3). A retrospective review of these injuries was performed. The ulnar nerve was injured in 19, the median nerve in ten and the radial nerve in eight cases. Fourteen neuropathies were noted at the initial presentation and 23 were diagnosed after treatment of the fracture. After referral, exploration of the nerve was planned for 13 patients. Surgery was later cancelled in three because of clinical recovery. Six patients underwent neurolysis alone. Excision of neuroma and nerve grafting were performed in four. At follow-up, 26 patients had an excellent, five a good and one a fair outcome

Nerve damage is a complication of THA and TKA procedures. The incidence of subclinical nerve injury following arthroplasty is unknown. The aim was to determine the prevalence of asymptomatic nerve deficits in an arthroplasty population group, and the incidence of post-operative changes in nerve function. A Secondary aim was to identify the nature of any deficits. And the association between nerve deficits and history of backache. A non-randomised prospective series of patients undergoing lower limb arthroplasty for osteoarthritis were studied at a single hospital. The peroneal nerve was investigated using nerve conduction in forty patients. Twenty patients had upper limb testing to differentiate between a polyneuropathy or isolated lower limb neuropathy. Nerve function deficits were detected in the peroneal nerve in fifteen patients pre-operatively and fifteen post-operatively, of those twelve had A waves detected suggestive of a generalised neuropathy. Ten patients who had upper limb testing had a conduction defect (five had asymptomatic Carpal tunnel). There was a positive correlation between presence of post-operative deficit and age(r=0.389, p=0.013). A negative correlation was found for presence of post-operative A waves and BMI(r=−0.370, p=0.019). The prevalence of pre-operative subclinical peroneal neuropathy is much higher than expected in this group (37.5%) of arthroplasty patients. There is a strong correlation between presence of post-operative conduction abnormalities and age. There is no relationship between peripheral neuropathy and history of backache or residual post-operative deficit

The outcomes of 261 nerve injuries in 100 patients were graded good in 173 cases (66%), fair in 70 (26.8%) and poor in 18 (6.9%) at the final review (median 28.4 months (1.3 to 64.2)). The initial grades for the 42 sutures and graft were 11 good, 14 fair and 17 poor. After subsequent revision repairs in seven, neurolyses in 11 and free vascularised fasciocutaneous flaps in 11, the final grades were 15 good, 18 fair and nine poor. Pain was relieved in 30 of 36 patients by nerve repair, revision of repair or neurolysis, and flaps when indicated. The difference in outcome between penetrating missile wounds and those caused by explosions was not statistically significant; in the latter group the onset of recovery from focal conduction block was delayed (mean 4.7 months (2.5 to 10.2) vs 3.8 months (0.6 to 6); p = 0.0001). A total of 42 patients (47 lower limbs) presented with an insensate foot. By final review (mean 27.4 months (20 to 36)) plantar sensation was good in 26 limbs (55%), fair in 16 (34%) and poor in five (11%). Nine patients returned to full military duties, 18 to restricted duties, 30 to sedentary work, and 43 were discharged from military service. Effective rehabilitation must be early, integrated and vigorous. The responsible surgeons must be firmly embedded in the process, at times exerting leadership

Introduction. Anterior Cruciate ligament reconstruction is a common operation in orthopaedics surgery. A common complication of whilst havesting the hamstring tendon is injury to the infra-patellar branch of the saphenous nerve (IPBSN), resulting in altered sensation to the anterior and lateral aspects of the knee and leg. Aim. The aim of this study was to further understand the course of this nerve in relation to surgical approach to anterior cruciate ligament reconstruction. Material and method. The nerve was traced and dissected in 25 knees from 14 different cadavers. Four paths of IPBSN in relation to the Sartorius muscle were identified: (1) a posterior path which ran round the inferior posterior border of the muscle, (2) a transmuscular path that penetrated through the muscle, (3) an anterior path that ran from the anterior border of the muscle and (4) posterior patellar path that ran round the posterior of the muscle at the same level as the patellar. Dissections were carried out with further 14 knees in a standard manner using both type of incision techniques, vertical incision or horizontal, in ten pair of knees. Using a tendon stripper, the hamstrings tendon were harvested in a standard fashion in different angles of the knee ie full extension and flexion at 90 degrees. Results. Of these paths the posterior was the most common featuring in 57% of specimens and the nerve was at higher risk of being injured due to the proximity of that pathway and the gracilis and semintendinosus muscle tendons. Horizontal incision has a higher chance of damage to the saphenous nerve and the infra-patellar branch. The saphenous nerve was injured on every occasion by this incision. Vertical incision, 1.5cm from the midline, avoided the infra-patellar branch and the saphenous nerve. Harvesting of the tendon in full extension was difficult, and it made the incision sites both horizontal and vertical at greater risk injuring the tendons. When the knee was flexed at 90 degrees these problems were overcome. Conclusions. A vertical incision with a flexed knee gave the best method to harvest the tendon with minimal risk to damaging the infra-patellar branch and the saphenous nerve when using the tendon stripper

Background:. Potential injury to the common peroneal nerve at the level of the fibula head/neck junction during fine wire insertion in stabilization of proximal fibula, is a recognised complication. This study aims to relate the course of the common peroneal nerve to fibula head transfixion wire. Methods:. Standard 1.8mm Ilizarov wires were inserted percutaneously in the fibula head of cadaveric knees. The course of the common peroneal nerve was dissected calculating wire to nerve distance. Results:. The common peroneal nerve was seen to cross the neck of fibula at a mean distance of 34.8mm from the tip of fibula (range 21.5–44.3mm). Wire placement was found to be on average, 52% of the maximal AP diameter of the fibula head and 64% of the distance from tip of fibula to the point of nerve crossing fibula neck. Conclusion:. When inserting a fibula head transfixion wire, care must be taken not to place wire entry point too distal or posterior on the fibula head. Observing a safe zone in the anterior half of the proximal 20mm of the fibula head would avoid injury to the nerve. In cases where palpation of fibula is difficult, we recommend wire insertion under fluoroscopic guidance

Fractures of the distal third of the humerus may be complicated by complete lesions of the radial nerve which may be entrapped or compressed by bone fragments. Indirect reduction and internal fixation may result in a permanent nerve lesion. We describe the treatment of these lesions by insertion of a bridge plate using the minimally-invasive percutaneous technique. Six patients were operated on and showed complete functional recovery. Healing of the fractures occurred at a mean of 2.7 months (2 to 3) and complete neurological recovery by a mean of 2.3 months (1 to 5). In one patient infection occurred which resolved after removal of the implant

Percutaneous stabilisation of tibial fractures by locking plates has become an accepted form of osteosynthesis. A potential disadvantage of this technique is the risk of damage to the neurovascular bundles in the anterior and peroneal compartments. Our aim in this anatomical study was to examine the relationship of the deep peroneal nerve to a percutaneously-inserted Less Invasive Stabilisation System tibial plate in the lower limbs of 18 cadavers. Screws were inserted through stab incisions. The neurovascular bundle was dissected to reveal its relationship to the plate and screws. In all cases, the deep peroneal nerve was in direct contact with the plate between the 11th and the 13th holes. In ten specimens the nerve crossed superficial to the plate, in six it was interposed between the plate and the bone and in the remaining two specimens it coursed at the edge of the plate. Percutaneous insertion of plates with more than ten holes is not recommended because of the risk of injury to the neurovascular structures. When longer plates are required we suggest distal exposure so that the neurovascular bundle may be displayed and protected

Introduction. The role of in-situ decompression in patients with severe ulnar nerve compression is still controversial. The authors present a prospective study on the results of in-situ decompression in this selected group of patients treated through a mini open incision (4cms) and complete decompression by appropriate patient positioning. Material/Methods. Thirty patients (20 Male/10 Female) with severe degree of nerve compression, confirmed clinically by Dellon's classification and by abnormal Nerve Conduction Study, underwent simple in-situ decompression under general anaesthesia as a day-case procedure. Through a 4cms incision and by moving the elbow the nerve is fully visualised and decompressed. Outcome was measured prospectively at three months and one year using Modified Bishop's score, grip strengths and two point discrimination (2PD). Results/Statistics. The average age of patients were 58.3 (26–87) and dominant hand was involved in 13 patients. Patients showed improvement greater at 1year than at 3 months. There was statistically significant improvement in power (p-0.01) and pinch grip strength (p-0.001) at one year after surgery. According to Modified Bishop's scoring, 24 patients (80%) had good to excellent results at one year follow-up. Of the eight patients with fair results at three months four improved and two detiorated, leading to a total of four poor results (13.3%) at one year follow-up. The 2PD identified the patients with poor or good results according to the Modified Bishop score at three months follow-up. Conclusions. Our results show that the minimally invasive in-situ decompression is technically simple, safe and gives good results in patients with severe nerve compression. The Modified Bishop score and 2PD were more reliable in assessing these patients at follow-up

The purpose of this study was to evaluate the results of subcutaneous ulnar nerve transposition in the treatment of Cubital Tunnel Syndrome (CTS) and the influence of prognostic factores such as preoperative McGowan stage, age and duration of symptoms. 36 patients (17 men and 19 women) with CTS who underwent subcutaneous ulnar nerve transposition between 2006 and 2009 were evaluated postoperatively, an average follow-up of 28 months. Sensory and motor recovery was evaluated clinically. The postoperative outcome was based on modified Bishop score, subjective assessment of function and on the degree of patient satisfaction. The dominant side was involved in 61% cases and the mean age was 51.2 years. There were 9 (25%) McGowan stage I, 18 (50%) stage II and 9 stage III patients. We used the Mann-Whitney and Kruskal-Wallis test to compare continuous variables and chi-square and Fisher Exact Test for categorical variables. There was a statistically significant improvement of sensory (p=0.02) and motor (p=0.02) deficits. We obtained 21 (58.3%) excellent results, seven (19.4%) fair, six (16.7%) satisfactory, and two bad ones (5.55%). There was a statistically significant improvement of function (p<0.001). There is controversy in the literature regarding the best surgical treatment for CTS. The duration and severity of symptoms and advanced age, more than the surgical technique, seem to influence prognosis. With the technique used, the satisfaction rate was 86% and 72% recovered their daily activities without limitations. 78% of patients with severe neuropathy improved after surgery. The rates of postoperative complications were comparable with those of other studies. The severity of neuropathy and duration of symptoms (>12months) pre-operatively, but not age, had a negative influence on the outcome. The results showed that the subcutaneous ulnar nerve transposition is safe and effective for postoperative clinical sensory and motor recovery for several degrees of severity in CTS. Given the major prognostic factors, surgical treatment should be advocated as soon as axonal loss has become clinically evident

Introduction. The flexor carpi radialis (FCR) approach is widely used for volar plate fixation of distal radius fractures. However, patients sometimes complain of postoperative numbness at the thenar eminence. We propose this is derived from injury to the palmar cutaneous branch of the median nerve (PCBm). Materials and methods. From March 2010 to March 2012, we performed 10 operations of volar plate fixation for distal radius fractures using the FCR approach. We detected the PCBm intraoperatively and investigated the anatomy. Results. On average, the PCBm arises from the median nerve 44 mm proximal to the distal wrist crease. It arose from the radial side of the median nerve in nine cases and the ulnar side in one case. In all cases, it ran between the FCR and the palmaris longus tendon under the antebrachial fascia. Nerve supply to the FCR sheath was not observed in the field of operation. Discussion. Numerous studies report the necessity to preserve the PCBm during carpal tunnel release surgery, but the relationship between the FCR approach and the PCBm has not been emphasized. Our results generally agree with past reports on PCBm anatomy. In our experience, the FCR tendon should be retracted to the ulnar side to prevent PCBm injury. If the FCR tendon is retracted radially, the PCBm should be detected and retracted gently. Some studies report that the PCBm joins the FCR sheath at the level of the distal wrist crease. Thus, the distal sheath incision should not be extended blindly

Multiligament knee injuries (MLKI) are associated with significant morbidity and healthcare requirements. The primary aim of this study is to report the patient reported outcomes measures (PROMs) after reconstructive surgery. Patients undergoing surgery for MLKI between 2014 and 2018 in the single large-volume trauma centre were included. Electronic patient records were reviewed for demographic data, details of surgery and complications. PROMs collected were EQ-5D-5L, Lysholm Knee Score (LKS), UCLA Activity and Sport and patient satisfaction. Thirty-five patients were included. Mean age was 31 years (range 16-66), and 71% were male. The most common mechanism of injury was sports-related (71%). Obesity was present in eight (23%) patients. No vascular injuries were recorded and four patients sustained nerve injuries. PROMs were available for 18 patients (51%) with a median follow up of 4.5 years. Median EQ-5D-5L was 0.78 (IQR 0.14). Median LKS was 84.5 (IQR 21) and there was no correlation with time to surgery (p=0.43). Grade of MLKI did not impact LKS (p=0.09). Fifteen patients (83%) saw a reduction in their activity level. All patients were satisfied with their surgical treatment. Recurrent instability was noted in four patients (11%). Three patients (8%) required further surgery (one revision reconstruction, one meniscectomy, one conversion to a hinged knee replacement. This study demonstrates two groups of patients who sustain MLKI: the sporting population and obese patients. Health related quality of life, functional outcomes and satisfaction are high after surgery. Time to surgery did not impact on functional outcomes

Reconfiguration of elective orthopaedic surgery presents challenges and opportunities to develop outpatient pathways to reduce surgical waiting times. Dupuytren's disease (DD) is a benign progressive fibroproliferative disorder of the fascia in the hand, which can be disabling. Percutaneous-needle-fasciotomy (PNF) can be performed successfully in the outpatient clinic. The Aberdeen hand-service has over 10 years' experience running dedicated PNF clinics. NHS Grampian covers a vast area of Scotland receiving over 11749 referrals to the orthopaedic unit yearly. 250 patients undergone PNF in the outpatient department annually. 100 patients who underwent PNF in outpatients (Jan2019–Jan2020). 79M, 21F. Average age 66 years range (29–87). 95 patients were right hand dominant. DD risk factors: 6 patients were diabetic, 2 epileptic, 87 patients drank alcohol. 76 patients had a family history of DD. Disease severity, single digit 20 patients, one hand multiple digits in 15 patients, bilateral hands in 65 patients of which 5 suffered form ectopic manifestation suggestive of Dupuytren's diasthesis. Using Tubiana Total flexion deformity score pre and post fasciotomy. Type 1 total flexion deformity (TFD) between 0–45 degrees pre PNF n=60 post N= 85, Type 2 TFD 45–90 degrees pre PNF n=18 post N=9, Type 3 TFD 90–135 pre PNF n=15 post N= 5, Type 4 TFD >135 pre PNF n=1 post PNF N=1. Using Chi-square statistical test, a significant difference was found at the p<0.05 between the pre and post PNF TFD. Complication: 8 recurrence, 1 skin tear. No patients sustained digital nerve injury. Outpatients PNF clinics are a valuable resource

Aims. The aim of this study was to determine the current incidence and epidemiology of humeral diaphyseal fractures. The secondary aim was to explore variation in patient and injury characteristics by fracture location within the humeral diaphysis. Methods. Over ten years (2008 to 2017), all adult patients (aged ≥ 16 years) sustaining an acute fracture of the humeral diaphysis managed at the study centre were retrospectively identified from a trauma database. Patient age, sex, medical/social background, injury mechanism, fracture classification, and associated injuries were recorded and analyzed. Results. A total of 900 fractures (typical 88.9%, n = 800/900; pathological 8.3%, n = 75/900; periprosthetic 2.8%, n = 25/900) were identified in 898 patients (mean age 57 years (16 to 97), 55.5% (n = 498/898) female). Overall fracture incidence was 12.6/100,000/year. For patients with a typical fracture (n = 798, mean age 56 years (16 to 96), 55.1% (n = 440/798) female), there was a bimodal distribution in men and unimodal distribution in older women (Type G). A fall from standing was the most common injury mechanism (72.6%, n = 581/800). The majority of fractures involved the middle-third of the diaphysis (47.6%, n = 381/800) followed by the proximal- (30.5%, n = 244/800) and distal-thirds (n = 175/800, 21.9%). In all, 18 injuries (2.3%) were open and a radial nerve palsy occurred in 6.7% (n = 53/795). Fractures involving the proximal- and middle-thirds were more likely to occur in older (p < 0.001), female patients (p < 0.001) with comorbidities (p < 0.001) after a fall from standing (p < 0.001). Proximal-third fractures were also more likely to occur in patients with alcohol excess (p = 0.003) and to be classified as AO-Orthopaedic Trauma Association type B or C injuries (p < 0.001). Conclusion. This study updates the incidence and epidemiology of humeral diaphyseal fractures. Important differences in patient and injury characteristics were observed based upon fracture location. Injuries involving the proximal- and middle-thirds of the humeral diaphysis should be considered as fragility fractures. Cite this article: Bone Joint J 2020;102-B(11):1475–1483

The aim was to report operative complications, radiographic and patient-reported outcomes following lateral tibial plateau fracture fixation augmented with calcium phosphate cement (CPC). From 2007–2018, 187 patients (median age 57yrs [range 22–88], 63% female [n=118/187]) with a Schatzker II/III fracture were retrospectively identified. There were 103 (55%) ORIF and 84 (45%) percutaneous fixation procedures. Complications and radiographic outcomes were determined from outpatient records and radiographs. Long-term follow-up was via telephone interview. At a median of 6 months (range 0.1–138) postoperatively, complications included superficial peroneal nerve injury (0.5%, n=1/187), infection (6.4%, n=12/187), prominent metalwork (10.2%, n=19/187) and post-traumatic osteoarthritis (PTOA; 5.3%, n=10/187). The median postoperative medial proximal tibial angle was 89o (range 82–107) and posterior proximal tibial angle 82o (range 45–95). Three patients (1.6%) underwent debridement for infection and 27 (14.4%) required metalwork removal. Seven patients (4.2%) underwent total knee replacement for PTOA. Sixty percent of available patients (n=97/163) completed telephone follow-up at a median of 6yrs (range 1–13). The median Oxford Knee Score was 42 (range 3–48), Knee injury and Osteoarthritis Outcome Score 88 (range 10–100), EuroQol 5-Dimension score 0.812 (range −0.349–1.000) and Visual Analogue Scale 75 (range 10–100). There were no significant differences between ORIF and percutaneous fixation in patient-reported outcome (all p>0.05). Fixation augmented with CPC is safe and effective for lateral tibial plateau fractures, with a low complication rate and good long-term knee function and health-related quality of life. Percutaneous fixation offers a viable alternative to ORIF with no detriment to patient-reported outcome
