Aims

This study assesses patient barriers to successful telemedicine care in orthopaedic practices in a large academic practice in the COVID-19 era.

Initially, all surgeons in Australia were generalists and those with an interest in the anatomy of the hand performed hand surgery. Early hand surgeons, such as Benjamin Rank, excelled and Rank and Wakefield's Textbook of Hand Surgery was widely used throughout the world. Eventually, groups of like-minded surgeons formed the Australian Hand Club in 1972, which subsequently became formalised as The Australian Hand Surgery Society (AHSS), in 2001. A very high standard of hand surgery has been achieved in Australia, with most hand surgeons having trained in either plastic surgery or orthopaedic surgery, and then further trained in Fellowships in Europe or North America. Bernard O'Brien and John Hueston achieved international recognition in the field of microsurgery and Dupuytren's surgery. Wayne Morrison has been responsible for pioneering work in toe–to–hand transfer and basic research. Tim Herbert changed the way fractures of the scaphoid are managed throughout the world. In 2007 the AHSS commenced a Travelling Fellowship Programme to facilitate an increased involvement in Australia in academic hand surgery and to foster contacts between hand surgeons of the future. At the present time, the AHSS is concentrating on education and training in order to raise the overall standard of management of hand surgery, particularly in relation to after hours' trauma. This is particularly necessary in rural and regional areas where hand surgery has traditionally been treated by occasional practitioners. There is a risk that hand surgery falls between the two stools of plastic surgery and orthopaedic surgery and the AHSS wishes to further formalise training and education within the Royal Australasian College of Surgeons (RACS) as a single training stream in the future. There are potential threats both within and without, with safe working hours a particular threat in relation to reducing both the quantity and quality of training. The future will almost certainly involve greater emphasis on biomaterials and prosthetic compounds, but trying to ensure a uniformly high standard of hand surgery management throughout the country will remain as a primary focus

Distal radius fractures are the most common upper extremity injury, and are increasingly being treated surgically with pre-contoured volar-locking plates. These plates are favored for their low-profile template while allowing for rigid anatomic fixation of distal radius fractures. The geometry of the distal radius is extremely complex, and little evidence within the medical literature suggests that current implant designs are anatomically accurate. The main objective of this study is to determine if anatomic alignment of the distal radii corresponds accurately with modern volar-locking plate designs. Additionally, this study will examine sex-linked differences in morphology of the distal radius. Segmented CT models of ten female cadaver (mean age, 88.7 ± 4.57 years, range, 82 – 97) arms, and ten male cadaver (mean age, 86 ± 3.59 years, range, 81 – 91) arms were created. Micro CT models were obtained for the DePuy Synthes 2.4mm Extra-articular (EA) Volar Distal Radius Plate (4-hole and 5-hole head), and 2.4mm LCP Volar Column (VC) Distal Radius Plate (8-hole and 9-hole head). Plates were placed onto the distal radii models in a 3D visualization software by a fellowship-trained orthopaedic hand surgeon. The percent contact, volar cortical angle (VCA), border and overlap of the watershed line (WSL) were measured. Both sexes showed an increase in the average VCA measure from medial to lateral columns which was statistically significant. Female VCA ranged from 28 – 36 degrees, and 38 – 45 degrees for males. WSL overlap ranged from 0 – 34.7629% for all specimens without any statistical significance. The average border distance for females was 2.58571 mm, compared to 3.52411 mm for males, with EA plates having a larger border than VC plates. The border distances had statistically significant differences between the plate types, and was approaching significance between sexes. Lastly, a maximum percent contact of 21.966 % was observed in specimen F4 at a 0.3 mm threshold. No statistical significance between plate or sex populations was observed. This study investigated the incoherency between the volar cortical angle of the distal radius, and the pre-contoured angle of volar locking plates. It was hypothesized that if the VCA measures between plate and bone were unequal then there would be an increase in watershed line overlap, and decrease in percent contact between the surfaces. Our results agreed with literature, indicating that the VCA of bone was larger than that of the EA and VC pre-contoured plates examined in this study. With distal radius fracture incidences and prevalence on the rise for elderly female patients, it is a necessity that volar locking plates be re-designed to factor in anatomical features of individual patients with a particular focus on sex differences. New designs should focus on providing smaller head sizes that are more accurately tailored to the natural contours of the volar distal radius. It is recommended that future studies incorporate expertise from multiple surgeons to diversify and further understand plate placement strategies

Distal radius fractures are the most common upper extremity fracture. The incidence is significantly higher in elderly females with osteoporotic bone. When surgery is indicated, volar locking plates (VLPs) allow for rigid fixation particularly in comminuted fractures with poor bone quality. Although numerous studies have shown the importance of plate placement to avoid soft tissue complications associated with volar plate fixation, there has been little evidence on the anatomic fit of current VLPs. Moreover, the effect of gender differences in distal radius morphology on anatomic fitting of VLPs has not been studied. The aim of this study was to evaluate the gender difference in distal radius morphology and the accuracy of the fit of a current VLP to CT-based distal radius models. Segmented CT models of ten female (mean age, 89 ± 5 years), and ten male (mean age, 86 ± 4 years) cadaveric wrists were obtained. Micro-CT models of the DePuy-Synthes 4-hole extra-articular (EA) and 8-hole volar column (VC) distal radius VLPs were created. A 3D visualization software was used to simulate appropriate plate placement on to the distal radius models by a fellowship-trained hand surgeon. Volar cortical angles (VCA) of the medial, middle and lateral portion of the distal radius were measured and compared between genders. The accuracy of the fit of the two VLP designs were quantified using the percentage of the watershed line (WSL) overlapped by the plate (WSL overlap), the distance between the WSL and the most distal aspect of the posterior plate (prominence distance) and the percentage of contact between the plate and bone. There were statistically significant gender differences in medial, middle and lateral VCAs (p=.003 medial, p=.0001 middle, p=.002 lateral). VCA ranged from 28° to 36° in females and from 38° to 45° in males. The WSL overlap did not show statistically significant gender differences (male: 5.9%, female: 13.6%, p=.174). However, the difference in prominence distance between different genders approached statistical significance (male: 3.5mm, female: 2.6mm, p=.087). Contact mapping between the plate and bone did not demonstrate a perfect contact in any of our specimens. Thus, contact measurements were categorized into 0.1mm, 0.2mm, and 0.3mm threshold contacts. There were no statistically significant gender differences in any of the threshold categories (0.1mm: p=.84, 0.2mm: p=.97, 0.3mm: p=.99). Our results confirm that there are gender differences in distal radius morphology. Current plate designs incorporate a VCA of 25° which does not match the native VCA of the distal radius in males or females. Although the difference in prominence distance approached statistical significance, there were no statistically significant gender differences in the WSL overlap or the contact threshold values. This lack of statistical significance may be related to the small sample size. This study proposes novel methods of assessing the anatomic fit of current VLPs in a 3D CT-based model that may be used in future studies with a larger sample size. Moreover, this study demonstrated the importance of considering gender differences in distal radius morphology in the design of future generations of implants

Practice variation may occur when there is no standardised approach to specific clinical problems and there is a lack of scientific evidence for alternative treatments. Practice variation suggests that a segment of the patient population may be managed sub-optimally, and indicates a need for further research in order to establish stronger evidence-based practice guidelines. We surveyed Australian orthopaedic surgeons to examine practice variation in common orthopaedic presentations. In February 2009, members of the Australian Orthopaedic Association were emailed an online survey, which collected information regarding experience level (number of years as a consultant), sub-specialty interests, state where the surgeon works, on- call participation, as well as five common (anecdotally controversial) orthopaedic trauma cases with a number of management options. Surgeons were asked to choose their one most likely management choice from the list provided, which was either surgical or non-surgical in nature. A reminder was sent two weeks later. Exploratory regression was modeled to examine the predictors of choosing surgical management for each case and overall. Of 760 surgeons, 358 (47%) provided responses. For undisplaced scaphoid fractures, respondents selected short-arm cast (53%), ORIF (22%), percutaneous screw (22%) and long-arm cast (3%). Less experienced (0 to 5 years) (p=0.006) and hand surgeons (p=0.008) were more likely to operate. For a displaced mid-shaft clavicle fracture, respondents selected non-operative (62%), plating (31%) and intramedullary fixation (7%). Shoulder surgeons were more likely to operate (p<0.001). For an undisplaced Weber B lateral malleolus fracture, respondents selected plaster cast or boot (59%), lateral plating (31%), posterior plating (9%) and no splinting (2%). For a displaced Colles fracture in an older patient, respondents selected plating (47%), Kirschner wires (28%), cast/splint (23%) and external fixation (1%). Less experienced (p<0.001) and hand surgeons (p=0.024) were more likely to operate. For a two-part neck of humerus fracture in an older patient, respondents selected non-operative (74%), locking plate (14%), and hemiarthroplasty (7%). Shoulder surgeons were more likely to operate (p<0.001). Accounting for all answers in multiple regression modeling, it was found that more experienced surgeons (>15 years) were 25% less likely to operate (p=0.001). Overall, there was no difference among sub-specialties, or whether a surgeon participated in an on-call roster. Considerable practice variation exists among orthopaedic surgeons in the approach to common orthopaedic problems. Surgeons who identify with a sub-specialty are more likely to manage conditions in their area of interest operatively, and more experienced surgeons are less likely to recommend surgical management

Conventional teaching advises against using adrenaline with local anaesthetic near end-arteries due to risks of irreversible vasospasm, however there are benefits of adjunctive adrenaline including enhanced anaesthetic effect, prolonged duration and temporary haemostasis. Retrospective analysis was undertaken for all elective finger and distal palmar surgery using digital nerve or field blocks performed by four orthopaedic hand surgeons, during a two-year period in a large teaching hospital. Data collected from theatre databases and clinical notes included procedure type, anaesthetic agent, adrenaline use, tourniquet use and evidence of post-operative digital ischaemia or wound complications. 230 procedures (mean age 59 years) were performed, including 158 cases with plain anaesthetic only (2%, 1% Lidocaine or 0.25% Bupivicaine in 150, 4 and 4 cases respectively) and 72 cases with 0.25% Bupivicaine and adrenaline (1:200,000.) Mean anaesthetic volume was 7.5ml (7.2ml vs 8.0ml without and with adrenaline respectively.) Tourniquet was used in all cases without adrenaline but was not used in 21 (29%) of cases with adrenaline. Mean tourniquet time in each group was 16 minutes. Two post-operative infections occurred in the group without adrenaline with none in the adrenaline group and there were no cases of digital necrosis in either group. In the elective setting, adjunctive adrenaline with local anaesthetic does not increase the risk of post-operative infections or digital ischaemia. For proximal finger surgery, where digital tourniquets are often restrictive, using adrenaline can prevent the need for painful arm tourniquets

The comparison between surgical outcomes of trapeziectomy versus trapeziectomy with ligament reconstruction (LRTI) is well documented in the literature. We could not find any literature comparing these two procedures from a ‘patient-based outcome scoring’ perspective. The Patient Outcomes Of Surgery (POS) hand/arm questionnaire was used in order to assess the outcomes of 33 patients (23 Trapeziectomy and 10 LRTI). All surgery was carried out by the same hand surgeon. A telephone questionnaire was performed on each patient. The mean time post surgery was 15 months (range 1 to 27) and 20 months (range 7 to 30) for the Trapeziectomy and LRTI group respectively. There was statistically significant improvement in both groups for symptoms, physical activities and psychological functioning/cosmetic appearance. The Trapeziectomy alone group scored higher in all groups though this did not show statistical significance. There were statistically significant higher rates of complications in the LRTI group. LRTI surgery increased the tourniquet time by 28 minutes on average. Patient overall satisfaction was higher (85/100) in the trapeziectomy alone group than that of the LRTI group (75/100). Both trapeziectomy and trapeziectomy with LRTI offer a reliably way of treating arthritis of the carpometacarpal joint. In our study, Trapeziectomy alone resulted in better overall patient satisfaction with lower complication rates and reduced operating time

The ITS volar radial plate (Implant Technology Systems, Graz/Austria) is a fixation device that allows for the distal locking screws to be fixed at variable angles (70°-110°). This occurs by the different material properties, with the screws (titanium alloy) cutting a thread through the plate holes (titanium). We present our experience with the ITS plate. We retrospectively studied 26 patients who underwent ITS plate fixation for unstable multifragmentary distal radial fractures (AO types A3, B2, B3, C2, C3). The surgery was performed either by a consultant orthopaedic hand surgeon or senior registrar. A volar approach was used every time and 10 cases required synthetic bone grafting. Post-operatively they were immobilised for an average of 2.5 weeks. The 26 patients had a mean age of 58 and the dominant side was affected in 46% of cases. 5 cases were open fractures and 10 cases followed failed manipulation under general anaesthesia. The average interval between injury and surgery was 7 days. Union was achieved in all cases. No implant infections, failure or tendon rupture/irritation occurred. There were two fractures which loss reduction, of which one required revision surgery. There was one case of CRPS. The six month average DASH score was 27.5. We consider the ITS plate a technically easy plate to use and a reliable implant at early follow-up. We value the versatility of its variable angle screw fixation ability for complex intra-articular distal radial fractures

Giant cell tumours of tendon sheaths have been given multiple denominations due to the uncertain pathologic nature of this lesion. Various contributory factors have been accounted for a wide variation in their recurrence rates. Owing to their high recurrence rates ranging from 9% to 44%, these tumours continue to present with treatment dilemma. There is a lack of consensus regarding how to best manage the balance between extensive dissection and preservation of normal tissues for normal function and recovery versus the risk of recurrence. The authors studied 46 patients with histopathologically confirmed Giant cell tumours over a period of 9 years between 1997 and 2006. The average follow-up in this case series was 35 months. This study aims to analyse the distribution of giant cell tumours of tendon sheaths in hand and our experience with their resection in a District General Hospital with possible predictors associated with recurrence. The referral letters, radiographs, operative and histology records were reviewed. The data was carefully analysed including patients' age and sex at the time of presentation and surgery, presenting symptoms, any associated trauma and the anatomical location of the tumour. A telephonic questionnaire was conducted and the patients with any complications or recurrence were reviewed. Our recurrence rate of 8.6% (4 patients) is lower than previously reported in the literature when the patients did not receive post-operative radiotherapy. Recurrence was seen to be statistically higher in cases where the tumours were excised piecemeal as opposed to removed in one piece and in patients with osseous erosions which were confirmed radiologically and intra-operatively. No atypical mitosis was reported on histology. None of our patients received radiotherapy post-operatively. Other factors including age, size, degenerative joint disease and location within the digit were not confirmed as risk factors in our study. We recommend meticulous surgical technique by an experienced hand surgeon and warning patients of the risk of recurrence if any risk factors were identified

Late presentation and rapid progression of Dupuytren's contracture significantly increases operating time, complications and likelihood of incomplete correction; however, surgical timing is usually more a function of waiting list length than of clinical criteria. We sought to measure the rate of progress of Dupuytren's contracture. All patients with Dupuytren's contracture referred to the sole Consultant Hand Surgeon for Highland Region between June 1997 and February 2003 were prospectively included. Fixed flexion deformities at each finger joint and thumb-index angle to the point of firm resistance to extension were recorded by a single observer (QGNC) at presentation and immediately pre-operatively. Of 151 participants 37% had a family history. There was a male predominance of 5:1, with bilaterality in 77% at presentation. Five percent had diabetes, 3% had epilepsy, 52% acknowledged tobacco habits and 24% regular alcohol in excess of recommended limits. Angular deterioration was observed in 52% of digits, over one quarter of this occurred at the small finger joints, where 58% of PIPJs progressed. Mean delay from presentation to surgery was 11 months (2-55.5). Mean age at presentation of 62 (16-86) years did not correlate with angular deformity at presentation or with velocity of deterioration or with manual/non-manual employment. Mean severity of deformity at presentation for manual (34°) was double non-manual workers (17°) although angular deterioration was faster in the non-manual group (3.8 cf 0.7°/month respectively). Similar speeds of deterioration were seen at MCPJ and PIPJ, speed of deterioration was 2.2°/month for each of the three ulnar digits. Speed of deterioration correlated (r=0.7) with severity of deformity at presentation for ring and small fingers. This study offers the first quantification of rate of deterioration in Dupuytren's contracture. This could be used as a waiting list tool to predict the delay before a digit is likely to pose increased surgical risk

Impaction grafting is an excellent option for acetabular revision. It is technique specific and very popular in England and the Netherlands and to some degree in other European centers. The long term published results are excellent. It is, however, technique dependent and the best results are for contained cavitary defects. If the defect is segmental and can be contained by a single mesh and impaction grafting, the results are still quite good. If, however, there is a larger segmental defect of greater than 50% of the acetabulum or a pelvic discontinuity, other options should be considered. Segmental defects of 25–50% can be managed by minor column (shelf) or figure of 7 structural allografts with good long term results. Porous metal augments are now a good option with promising early to mid-term results. Segmental defects of greater than 50% require a structural graft or porous augment usually protected by a cage. If there is an associated pelvic discontinuity then a cup cage is a better solution. An important question is does impaction grafting facilitate rerevision surgery? There is no evidence to support this but some histological studies of impacted allograft would suggest that it may. On the other hand there are papers that show that structural allografts do restore bone stock for further revision surgery. Also the results of impaction grafting are best in the hands of surgeons comfortable with using cement on the acetabular side, and one of the reasons why this technique is not as popular in North America

Aims

The aim of this study was to investigate surgeons’ reported change of treatment preference in response to the results and conclusion from a randomized contolled trial (RCT) and to study patterns of change between subspecialties and nationalities.

Introduction. Large variations in knee kinematics existed after conventional TKA. Different design of TKA showed different intra-operative kinematics with navigation system. Purpose. The purpose of this study was to compare the kinematics of the three different types of prosthesis in navigation-based in vivo simulation. (Material and Method) Studies were carried out on 15 osteoarthritis Knees using the CT-free navigation system (Kolibri Knee, Brain LAB). Fourteen patients were female and one patient was male with mean age of 72 years. Five knees were implanted with the CR knee, 5 knees were implanted with the PS knee and 5 knees were implanted with PS mobile knee by navigated measured resection technique (PFC-sigma knee system, DePuy, Warsaw, IN). Intra-operative knee kinematics during passive range of motion from full extension to 130 degrees of knee flexion was measured after implantation while patella reduced and tourniquet released. While supporting the foot with one hand, the surgeon used his opposite hand to gently lift the thigh, flexing the hip and knee. Three types of prosthesis were compared for following factors: Presence of condylar lift-off (the gap difference greater than 1mm between medial gap and lateral gap) and anterior-posterior (AP) displacement of the center of femur relative to the tibia. Results. Lateral condylar lift-off was found in patients with the PS implant between 120° and 130° of flexion. Remaining two types of implant did not show the condyar lift-off (Fig. 1). The pattern of AP displacement showed the same manner in three implants. Femur moved anterior side form extension to 50∼55° of flexion, after that, femur moved posterior side to full flexion. The mean maximum anterior movement and angle in CR implant was 14mm @ 55°, PS implant was 17mm ï¼ 50° and PS-mobile implant was 17mm @ 55°. The mean maximum posterior movement @ 130°, CR implant was −10.5mm, PS implant was −8.3mm and PS-mobile implant was −6.9mm. There was no significant difference among three groups. Discussion. In CR implant, the function of PCL could influence to prevent the condyar lift-off. In PS-mobile implant, the mechanism of rotation platform might have contributed to prevent the condylar lift-off. The paradoxical anterior slide of the femoral condyles during mid flexion was observed in all types of implant. We could not find any difference in AP displacement of these 3 types of prosthesis

Recurrent shoulder instability in those with bony defects is a difficult surgical problem to resolve. Burkhart and De Beer described an unacceptably high recurrence rate for arthroscopic Bankart repair in the presence of an inverted-pear glenoid with or without an engaging Hill-Sachs lesion, with suggestions that an open modified Latarjet procedure should be recommended in such patients. The Congruent-Arc Latarjet is a modification of the Latarjet open bony stabilisation for shoulder instability developed by Burkhart and De Beer. It involves rotation of the coracoid so the curved under-surface lies congruent with the glenoid. At the Royal Derby Hospital, UK, this procedure has been adopted by our four shoulder surgeons, two of whom undertook fellowship training with De Beer, we studied the outcomes of the patients who had undergone the modified Congruent-Arc Latarjet procedure in our department. Fifty-two consecutive patients were identified over a five-year period at the Royal Derby Hospital or Derbyshire Royal Infirmary between 2006 and 2010 inclusive. With the approval of the clinical audit department, the data was collected using theatre records and clinical coding information to identify the patient group. A review of the case notes and local PACS system was undertaken to establish pre and post-operative examination findings, radiology findings regarding Hill-Sachs defects and glenoid bone loss, re-dislocation rates and post-operative function with return to normal activity. The endpoints of this study were aimed at finding out whether patients did return to normal function, were able to continue doing activity that would have provoked dislocation prior to surgery, and how many of the cases re-dislocated. No surgeon consultant had a patient who re-dislocated after this procedure. The follow-up period was from 1 year to 6 years post-operatively. The complications of this procedure were found to be the dislodgement of bone anchors in 2 patients, who required further arthroscopy to remove the suture anchor from the gleno-humeral joint. One patient had prolonged functionally limiting loss of external rotation, which resolved after intensive physiotherapy at 7 months follow up. We will provide graphical representation of the pre and post operative functional scores. We have demonstrated that the Congruent-Arc Latarjet is a reproducible procedure in the hands of surgeons other than the original authors, particularly when comparing our current 0% re-dislocation rate with the published literature, which suggests that 3.9% of patients undergoing this procedure with greater than 25% bone loss of the glenoid or an engaging Hill-Sachs will re-dislocate post-operatively, and this is better than the 6% re-dislocation rate of the standard Bristow-Latarjet procedure

Using inaccurate quotations can propagate misleading information, which might affect the management of patients. The aim of this study was to determine the predictors of quotation inaccuracy in the peer-reviewed orthopaedic literature related to the scaphoid. We randomly selected 100 papers from ten orthopaedic journals. All references were retrieved in full text when available or otherwise excluded. Two observers independently rated all quotations from the selected papers by comparing the claims made by the authors with the data and expressed opinions of the reference source. A statistical analysis determined which article-related factors were predictors of quotation inaccuracy. The mean total inaccuracy rate of the 3840 verified quotes was 7.6%. There was no correlation between the rate of inaccuracy and the impact factor of the journal. Multivariable analysis identified the journal and the type of study (clinical, biomechanical, methodological, case report or review) as important predictors of the total quotation inaccuracy rate.

We concluded that inaccurate quotations in the peer-reviewed orthopaedic literature related to the scaphoid were common and slightly more so for certain journals and certain study types. Authors, reviewers and editorial staff play an important role in reducing this inaccuracy.
