Aims. The aim of this study is to evaluate the change in incidence rate of shoulder arthroplasty, indications, and surgeon volume trends associated with these procedures between January 2003 and April 2021 in the province of Nova Scotia, Canada. Methods. A total of 1,545 patients between 2005 and 2021 were analyzed. Patients operated on between 2003 and 2004 were excluded due to a lack of electronic records. Overall, 84.1% of the surgeries (n = 1,299) were performed by two fellowship-trained upper limb surgeons, with the remainder performed by one of the 14 orthopaedic surgeons working in the province. Results. Total shoulder arthroplasty (TSA) was the most frequent procedure (32.17%; n = 497), followed by stemmed hemiarthroplasty (SHA) (27.7%; n = 428). The most frequent indication for primary shoulder arthroplasty was degenerative osteoarthritis (58.1%; n = 882), followed by acute proximal humerus fracture in 15.11% (n = 245), and rotator cuff arthropathy in 14.18% (n = 220). The overall rate of revision was 7.7% (2.8% to 11.2%). The number of TSAs and reverse shoulder arthroplasties (RSAs) has been increasing since 2016. The amount of revision cases is proportional to the number of operations performed in the same year throughout the study period. Conclusion. The incidence of shoulder arthroplasty in the Maritime Provinces has increased over the last 16 years. Revision rates are similar the those found in other large database registries. Reverse shoulder arthroplasty prevalence has increased since 2016. Cite this article: Bone Jt Open 2023;4(8):567–572

Aims. Shoulder arthroplasty is effective in the management of end-stage glenohumeral joint arthritis. However, it is major surgery and patients must balance multiple factors when considering the procedure. An understanding of patients’ decision-making processes may facilitate greater support of those considering shoulder arthroplasty and inform the outcomes of future research. Methods. Participants were recruited from waiting lists of three consultant upper limb surgeons across two NHS hospitals. Semi-structured interviews were conducted with 12 participants who were awaiting elective shoulder arthroplasty. Transcribed interviews were analyzed using a grounded theory approach. Systematic coding was performed; initial codes were categorized and further developed into summary narratives through a process of discussion and refinement. Data collection and analyses continued until thematic saturation was reached. Results. Two overall categories emerged: the motivations to consider surgery, and the information participants used to inform their decision-making. Motivations were, broadly, the relief of pain and the opportunity to get on with life and regain independence. When participants’ symptoms and restrictions prevented them enjoying life to a sufficient extent, this provided the motivation to proceed with surgery. Younger participants tended to focus on maintaining employment and recreational activities, and older patients were eager to make the most of their remaining lifetime. Participants gathered information from a range of sources and were keen to optimize their recovery where possible. An important factor for participants was whether they trusted their surgeon and were prepared to delegate responsibility for elements of their care. Conclusion. Relief of pain and the opportunity to get on with life were the primary reasons to undergo shoulder arthroplasty. Participants highlighted the importance of the patient-surgeon relationship and the need for accurate information in an accessible format which is relevant to people of different ages and functional demands.

Adequate visual clarity is paramount to performing arthroscopic shoulder surgery safely, efficiently, and effectively. The addition of epinephrine in irrigation fluid, and the intravenous or local administration of tranexamic acid (TXA) have independently been reported to decrease bleeding thereby improving the surgeon's visualization during arthroscopic shoulder procedures. No study has compared the effect of systemic administered TXA, epinephrine added in the irrigation fluid or the combination of both TXA and epinephrine on visual clarity during shoulder arthroscopy with a placebo group. The purpose of this study is to determine if intravenous TXA is a safe alternative to epinephrine delivered by a pressure-controlled pump in improving arthroscopic shoulder visualization during arthroscopic procedures and whether using both TXA and epinephrine together has an additive effect in improving visualization. The design of the study was a double-blinded, randomized controlled trial with four 1:1:1:1 parallel groups conducted at one center. Patients aged ≥18 years undergoing arthroscopic shoulder procedures including rotator cuff repair, arthroscopic biceps tenotomy/tenodesis, distal clavicle excision, subacromial decompression and labral repair by five fellowship-trained upper extremity surgeons were randomized into one of four arms: Pressure pump-controlled regular saline irrigation fluid (control), epinephrine (1ml of 1:1000) mixed in irrigation fluid (EPI), 1g intravenous TXA (TXA), and epinephrine and TXA (EPI/TXA). Visualization was rated on a 4-point Likert scale every 15 minutes with 0 indicating ‘poor’ quality and 3 indicating ‘excellent’ quality. The primary outcome measure was the unweighted mean of these ratings. Secondary outcomes included mean arterial blood pressure (MAP), surgery duration, surgery complexity, and adverse events within the first postoperative week. One hundred and twenty-eight participants with a mean age (± SD) of 56 (± 11) years were randomized. Mean visualization quality for the control, TXA, EPI, and EPI/TXA groups were 2.1 (±0.40), 2.1 (±0.52), 2.6 (±0.37), 2.6 (±0.35), respectively. In a regression model with visual quality as the dependent variable, the presence/absence of EPI was the most significant predictor of visualization quality (R=0.525; p < 0 .001). TXA presence/absence had no effect, and there was no interaction between TXA and EPI. The addition of MAP and surgery duration strengthened the model (R=0.529; p < 0 .001). Increased MAP and surgery duration were both associated with decreased visualization quality. When surgery duration was controlled, surgery complexity was not a significant predictor of visualization quality. No adverse events were recorded in any of the groups. Intravenous administration of TXA is not an effective alternative to epinephrine in the irrigation fluid to improve visualization during routine arthroscopic shoulder surgeries although its application is safe. There is no additional improvement in visualization when TXA is used in combination with epinephrine beyond the effect of epinephrine alone

Introduction and Aim: The metacarpal fractures constitute 10% of skeletal fractures in general affecting mainly children and young adults. There is a lot of discrepancy and lack of evidence with regards to correctly managing the little finger metacarpal fractures. Our study was aimed at investigating the current practice of management little finger metacarpal fractures among upper limb surgeons in United Kingdom. Methods: We conducted an online survey between June 2006 and June 2007 consisting of 10 multiple-choice questions that was e-mailed to 278 upper limb orthopaedic specialist surgeons. The response rate was 58% (n = 158) from the upper limb surgeons. Four questionnaires had to be excluded due to multiple responses to each question or incomplete forms. Results: 43% upper limb surgeons prefer neighbour strapping alone for non-operative management of little finger metacarpal fractures. Ulnar gutter cast or splint was the next choice among 19% upper limb surgeons while 13% respondents apply neighbour strapping to ring finger along with a splint. There was mixed response regarding period of immobilisation. 40% of surgeons were in favour of 3 weeks of immobilisation, 23% for 2 weeks while 28% do not immobilise these fractures at all. With regard to considering the most important indication(s) for surgical intervention, rotational deformity was the most common indication (84%), followed by open fracture (70%), intra-articular fracture (44%), associated 4th metacarpal fracture (26%), shortening > 5mm (21%) and volar angulation – (15%). If treated non-operatively, the most preferred period of fracture clinic follow up was one visit at 3 weeks by 40% while 36% thought that no follow up is required once decision is made to treat them conservatively. Conclusion: Isolated undisplaced fractures of little metacarpal are usually managed conservatively using a plethora of methods of immobilisation. The indications for operative intervention are open fracture, rotational deformity, intra-articular fractures and shortening. Many clinical studies have demonstrated that in the conservative care of boxer’s fractures (casting, with or without reduction), between 20 degrees and 70 degrees of dorsal angulation is acceptable. We conclude that contemporary literature provides no evidence as to whether conservative or operative methods of the treatment of these fractures is superior, but rather suggests that they are equally effective. We conclude from our survey that there is no consensus even among the upper limb surgeons with regards to management of little finger metacarpal fractures in United Kingdom

Post-traumatic elbow stiffness is a disabling condition that remains challenging for upper limb surgeons. Open elbow arthrolysis is commonly used for the treatment of stiff elbow when conservative therapy has failed. Multiple questions commonly arise from surgeons who deal with this disease. These include whether the patient has post-traumatic stiff elbow, how to evaluate the problem, when surgery is appropriate, how to perform an excellent arthrolysis, what the optimal postoperative rehabilitation is, and how to prevent or reduce the incidence of complications. Following these questions, this review provides an update and overview of post-traumatic elbow stiffness with respect to the diagnosis, preoperative evaluation, arthrolysis strategies, postoperative rehabilitation, and prevention of complications, aiming to provide a complete diagnosis and treatment path.

In the setting of traumatic elbow injuries involving coronoid fractures, the relative size of the coronoid fragment has been shown to relate to the stability of the joint. Currently, the challenge lies in accurately classifying the amount of bone loss in coronoid fractures. In comminuted fractures, bone loss is difficult to measure with plain radiographs or computed tomography. The purpose of this study is to describe a novel radiographic measure, the Coronoid Opening Angle (COA), on lateral elbow radiographs. We demonstrate the relationship of the COA to coronoid height and describe how this measure can be used to estimate bone loss and potentially predict elbow instability following coronoid fracture. Radiographs were drawn from a regional database in a consecutive fashion. Candidate radiographs were excluded on the basis of radiographic evidence of degenerative changes, previous surgery or injury, bony deformity, and inadequate lateral view of the elbow. The COA was measured as the angle between the long axis of the ulna at the level of the trochlear notch, and the tip of coronoid, from a common origin at the posterior cortex of the olecranon. Images were reviewed by a fellowship trained upper extremity surgeon, an upper extremity fellow, and a junior resident. Normal COA, coronoid height, and calculated COA at varying amounts of bone loss were calculated by three reviewers. A sensitivity analysis was performed to determine how the COA can most effectively predict bone loss at varying coronoid heights. Intraclass correlation coefficient (ICC) was calculated for 39 subjects. Seventy-two subjects were included for analysis (M=40, F=32). The normal coronoid opening angle is 33.19 degrees [32.2 – 34.2]. Coronoid height is 18.8 mm [18.1 – 19.6]. Extrapolating this baseline data, the COA at 20%, 33%, and 50% of coronoid bone loss was calculated to be 27.5, 23.5, and 18 degrees, respectively. ICC was found to be 0.90 or higher. Cutoff values were determined to maximize the sensitivity of the COA. A cutoff value of 21 degrees has a 92% sensitivity in detecting a minimum of 50% bone loss. The COA with similar sensitivity in predicting 20% and 33% bone loss are 32 and 27 degrees. The coronoid opening angle is a novel technique that can be used on a lateral elbow radiograph to predict the minimum coronoid bone loss. This can be used to guide clinical decision making and potentially predict instability. Future research will aim to validate this tool in the clinical setting in predicting instability

Purpose:. To examine the feasibility of surgical outcome measures for a children's orthopaedic surgeon when compared with other specialties. Methods & Results:. Details of procedure codes for 2726 inpatient episodes were used to examine the distribution of procedures and the breadth of diagnoses dealt with by a variety of orthopaedic sub-specialists. The author's practice included 199 surgical cases and was compared with two arthroplasty surgeons (n=971); a spinal surgeon (n=256); a foot and ankle surgeon (n=341) and an upper limb surgeon (n=393). Arthroplasty surgeons can report 50% of their outcomes as primary knee or hip replacements the index procedure for the author is metalwork removal (14.5%). My upper limb colleague could be judged on 25% of his cases (carpal tunnel decompression) and my spinal surgical colleague on 20% of his cases (primary posterior decompression of spinal cord). Only my foot and ankle colleague compared in terms of diversity with 9% of his cases consisting of first metatarsal osteotomy and the next 9% consisting of 1st MTPJ arthrodesis. The proportion of multiple procedures also varies between sub-specialists with 66% of my cases being multiple compared with 38% for the arthroplasty surgeons and 42% for the upper limb surgeons. Foot and ankle has a high rate of multiple procedures (62%) and the spinal surgeons code different procedures at each level in the spine giving the high rates of multiple procedures. Conclusion:. Outcome measures in children's orthopaedics seem problematic owing to the diverse nature of the practice and the confusion resulting from multiple procedures contributing to the outcome in 60% of cases. Either we are treated like physicians who do not have surgical outcomes to report or some goal based measure is adopted. Level of evidence: III

Background: The dorsal wrist ganglion is one of the commonest tumours to be found in the upper limb. Aims: We aimed to find out how specialist upper limb surgeons managed this common condition, and to propose best practice guidelines. Methods: We sent a standard questionnaire by email to 100 hand surgeons who were members of the British Society for Surgery of the Hand. Results: 62% returned the completed questionnaire. 93% routinely used a tourniquet, 73% used general anaesthetic. 83% would not use Xray or further imaging. 62% would operate on less than 10 a year or as few as possible. Only 42% routinely sent tissue for histology and 71% used a transverse incision. Discussion and Conclusions: Most upper limb surgeons diagnose a ganglion clinically, use a transverse incision for excision and do not routinely send tissue for histology. We believe that ganglia should be treated like other neoplasms and excised via a longitudinal incision and tissue sent for histology. We present a series of cases which were thought to be simple ganglia, but histology revealed different pathology. The use of a transverse incision, may compromise definitive excision at a later date, if histology revealed a malignant neoplasm. A transverse incision has not been shown to give superior results in terms of cosmesis, and is also associated with an increased risk of painful neuroma formation after damage to the superficial radial nerve

Introduction. The use of reverse total shoulder arthroplasty (RSA) is becoming increasingly common in the treatment of rotator cuff arthropathy. In recent years indications for use have expanded to include elderly patients in whom either internal fixation is not possible due to fracture configuration, poor bone quality, or presence of a rotator cuff deficiency. There is however relatively little evidence to support its use in these circumstances. Objective. This study aims to assess the viability of RSA as a salvage procedure in the treatment of complex proximal humeral fractures or irreducible dislocations, quantified in terms of functional outcome, complication rates and patient reported satisfaction. Methods. All patients presenting between January 2011 and December 2013 with a complex 3- or 4-part humeral fracture or a delayed presentation with an irreducible non-acute dislocation, treated with salvage RSA were eligible for inclusion. All operations were performed in a single centre by one of two specialist upper limb surgeons. Standard deltopectoral approach was performed. Tournier reverse fracture stem with two choices of inserts and graft hole in the stem with proximal hydroxyapatite coating was the implant of choice. All patients and underwent a standardised rehabilitation programme. Clinical outcome was measured at final follow up using (1) patient reported satisfaction, (2) clinician measured range of movement (3) complication rate. Results. A total of 16 patients were eligible for inclusion in this study. Mean age at time of operation was 72.8 years (41–91 years) with a mean follow-up of 7 months (2–13 months). At time of last follow-up 100 per cent of patients were satisfied with the results of their operation and functionally independent with activities of daily living. Mean oxford score was 39 (36–48). Range of movement post-operatively had a mean active forward extension 97° (70–150°) and abduction 101° (80–170°). 43% of patients were pain-free, whilst the remainder only required the use of occasional analgesia. One patient developed heterotrophic ossification post operatively and underwent surgical excision. One patient sustained a peri-prosthetic avulsion fracture at 18months treated non-operatively. Patients who underwent RSA for dislocation fared better than for those with proximal humeral fractures. The mean active forward extension was 107.5° (90–150°) and abduction 112.5° (90–170°) in the dislocation group (N=5) compared with those who had a fracture (N= 11) in which the forward extension was 91.4° (70–120°) and abduction 95° (80–120°). Conclusion. Reverse TSA should be considered in patients with complex proximal humeral fractures or delayed presentation with irreducible dislocation. Early results demonstrate good outcomes in terms of patient satisfaction, pain relief and preservation of function. These early result are encouraging however a further study with longer follow-up is required to confirm sustained benefit

Aims

The management of mid-shaft clavicle fractures (MSCFs) has evolved over the last three decades. Controversy exists over which specific fracture patterns to treat and when. This review aims to synthesize the literature in order to formulate an appropriate management algorithm for these injuries in both adolescents and adults.

Background. Steroid injections can be used safely to treat trigger fingers. We aimed to determine the accuracy of referring General Practitioner (GP) diagnoses of trigger finger made to an upper limb surgeon. We also aimed to determine the efficacy of a serial two steroid injection then surgery technique in the management of trigger fingers. Methods. Data was collected prospectively from a “one-stop” trigger finger clinic (based in a district general hospital). 200 trigger fingers identified from September 2005 to November 2008, giving a minimum 1 year follow-up. Data was analysed for correct referring diagnosis, resolution/recurrence rate following injection and the effect of age, injector grade, diabetes on the rate of recurrence. Results. GP diagnoses were correct in 94% of referrals. Recurrence free resolution after one steroid injection was achieved in 74% of cases, rising to 84% after a second injection. The grade of injector did not influence the rate of resolution (p=0.967) or recurrence (p=0.818). Age was the only statistically significant factor, with recurrences being 8.3 years younger (95% CI 4.1–12.6 yrs; p=0.0002). 15% required surgical release after failure of two steroid injections. Conclusions. Steroid injection for trigger finger is a safe, easily performed technique that can give recurrence free resolution in up to 84% using a serial two steroid injection technique. This is an easily acquired technique that has obvious potential to be performed in the primary care setting, thus reducing the burden on hospital based specialist upper limb services, as only 15% required surgical intervention

Aims

To achieve expert clinical consensus in the delivery of hydrodilatation for the treatment of primary frozen shoulder to inform clinical practice and the design of an intervention for evaluation.

The aim of the study was to compare the radiological findings of wrist arthrogram with wrist arthroscopy. This allowed us to establish the accuracy (sensitivity, specificity) of MRI arthrogram as a diagnostic tool. Thirty patients (20 female and 10 male) have undergone both wrist MRI arthrogram and wrist arthroscopy over the last 3 years at Macclesfield District General Hospital. The mean age at arthrogram was 42.4 years with an average 6.7 month gap between the two procedures. The MRI arthrogram was reported by a consultant radiologist with an interest in musculoskeletal imaging and the arthrosopies performed by two upper limb surgeons. Patients undergoing both procedures were identified. The arthrogram reports and operation notes were examined for correlation. Three main areas of pathology were consistently examined: TFCC (triangular fibrocartilage complex), scapholunate and lunatotriquetral ligament tears. The sensitivity and specificity of arthrogram was calculated for each. Other areas of pathology were also noted. In the case of TFCC tears MRI arthrogram had a 92.3% sensitivity and 54.6% specificity. The lunatotriquetral ligament examination with this technique was 100% sensitivity and specificity. However for scapholunate ligament tears it only had 50% sensitivity and 77.8% specificity. Wrist arthrogram and arthroscopy are both invasive techniques and equally time consuming. In cost terms the arthrogram remains cheaper but is superseded by arthroscopy as it is both diagnostic and therapeutic

In this study we reviewed all Total Elbow Replacements (TER) done in our hospital over eight years period (1997 – 2005), 21 patients (16 females, 5 males) were available for follow up and four were lost (two died and two moved out of the region) with average age of 65 years (range 44 – 77), all procedures were done by two upper limb surgeons (CHB & RGW). 16 patients (14 females, 2 males) had the procedure for Rheumatoid Arthritis and 5 patients (3 males, 2 females) undergone the procedure for post-traumatic arthritis. The average follow up was 61 months (range 12 – 120 months), the Mayo Clinic performance index, the DASH scores and activities of daily living (adopted from Secec Elbow Score) assessment tools were used. In addition, all patients were assessed for loosening using standard AP and lateral radiographs. Sixteen patients had Souter-Starthclyde prosthesis whilst three had Kudo and two had Conrad-Moorey prosthesis. All procedures were done through dorsal approach and all were cemented, the ulnar nerve was not transposed in any of the cases. The average elbow extension lag was 27 degrees (range 15 – 35) with flexion up to 130 degrees (range 110 – 140). Supination was 65 degrees (range 15 – 90) and pronation was 77 (range 55 – 90). The average DASH score was 51.3 (range 19 – 95), the Mayo elbow score was 82 (range 55 – 100) and the average Activities of daily living Secec Score was 17 (range 10 – 20). There were four complications, three ulnar nerve paresis which recovered and one wound complication which needed a flap cover. Two needed revision surgery, one for a periprosthetic fracture and one for loosening. Two patients showed radiological signs of loosening but were asymptomatic. The survival rate with revision as the end point is 95% for aseptic loosening and 90% for any other reason. Our study proves TER has good medium term results with good functional outcome and high patient satisfaction rate

Avulsion of the distal biceps tendon is an uncommon clinical entity accounting for 3% of all biceps tendon injuries. Various surgical techniques for its repair have been reported, however, the optimal technique is unknown. The two-incision technique is used by three upper limb surgeons at North Shore Hospital. There has been some concern regarding the risk of heterotopic bone formation with this technique. We present a review of a series of patients with distal biceps tendon ruptures treated with the modified two-incision technique to identify and describe any complications that we encountered and also assess the clinical, functional and radiological outcomes of our patients. Over a 4-year period from 2002–2006, 42 distal biceps tendons repairs using the two-incision technique were identified from the hospital database. All 42 patients were males with an average age of 51.9 years. Patients were followed-up prospectively and reviewed at a clinic where they filled out the SF-12 questionnaire and a Mayo Elbow Performance Score was assessed. Clinical assessment was carried out with regards to their range of flexion-extension and their pronation-supination. All peripheral nerves were examined. Isokinetic elbow flexion-extension and forearm pronation-supination were measured and compared to the unaffected extremity. X-rays were taken to identify heterotrophic ossification or proximal radioulnar synostoses. Our review, so far, indicates a good clinical and functional outcome in most of our patients. We identified one patient with heterotrophic bone formation requiring excision. Two patients had a transient lateral ante-brachial cutaneous nerve parasthesia and two patients had re-ruptures following surgery. This study represents a relatively large series of patients. Our results reveal that the two-incision technique is an effective surgical option for the repair of ruptured distal biceps tendons. We found that radioulnar synostoses and heterotrophic ossification are rare following the muscle splitting modification of the two-incision technique

Purpose. There have been a number of described techniques for sizing the diameter of radial head implants. All of these techniques, however, are dependent on measurements of the excised native radial head. When accurate sizing is not possible due to extensive comminution or due to a previous radial head excision, it has been postulated that the proximal radioulnar joint (PRUJ) may be used as an intraoperative landmark for correct sizing. The purpose of this study was to: 1) determine if the PRUJ could be used as a reliable landmark for radial head implant diameter sizing when the native radial head in unavailable, and (2) determine the reliability of measurements of the excised radial head. Method. Twenty-seven fresh-frozen denuded ulnae and their corresponding radial heads (18 males, 9 females) were examined. The maximum diameter (MaxD), minimum diameter (MinD) and dish diameter (DD) of the radial heads were measured twice, 3–5 weeks apart, using digital calipers. Two fellowship-trained upper extremity surgeons, an upper extremity fellow and a senior orthopedic resident were then asked to independently select a radial head implant diameter based on the congruency of the radius of curvature of the PRUJ to that of the radial head trial implants. The examiners were blinded to the native radial head dimensions. This selection was repeated 3–5 weeks later by two of the investigators. Correlation between radial head measurements and radial head implant diameter sizes was assessed using Pearsons correlation coefficient (PCC) and inter and intra-observer reliability were assessed using intra-class correlation coefficient (ICC). Results. There was a positive correlation between each of the radial head measurements (MaxD, MinD and DD) and the selected radial head implant diameters (PCC of 0.56, 0.59 and 0.51 respectively; p<0.01). Measuring the MaxD, MinD and DD of the radial head showed excellent inter-observer reliability (ICC of 0.99, 1.00 and 0.82 respectively) and excellent intra-observer reliability (ICC of 0.99, 0.98 and 0.75 respectively). The PRUJ sizing method used to determine the diameter of the radial head implant showed poor inter-observer reliability with an ICC of 0.34 but good intra-observer reliability (ICC = 0.76). Conclusion. Measurements of the diameter of the excised radial head showed excellent intra and inter-observer reliability suggesting that the excised radial head, when available, should be used to select the radial head implant diameter. The inter-observer reliability of using the PRUJ for sizing the diameter of radial head implants was poor, indicating that this method is an unreliable technique for radial head implant diameter sizing. However, the high intra-observer reliability of the PRUJ method indicates that an observer tends to make the same size estimation, even weeks apart. This study suggests that the PRUJ radius of curvature may be different than that of the radial head. Further studies are needed to verify this hypothesis

In recent years volar locking plates (VLP) have revolutionised the treatment of more complex distal radial fractures, but doubt still exists as to whether this is an operation for all suitably qualified orthopaedic surgeons, in particular experienced trainees, or remains the domain of consultants or better still upper limb surgeons. Aims: To assess changes in a Level 1 Trauma Unit’s practice over a 5 year period and to compare the clinical outcomes of patients operated upon by experienced orthopaedic trainees and consultant surgeons. Methods: Two prospective cohort studies were undertaken using (a) the Synthes VLP (January 2003–January 2005), and (b) the Periloc (Smith & Nephew) VLP (January 2007–February 2008). All patients were assessed at 6 months following surgery for range of movement, grip and pinch strength, and subjective levels of pain and function using Visual Numerical Scales. 65 and 36 patients were available for 6 month review in the Synthes and Periloc groups respectively. Operations undertaken by, or assisted directly by, the consultant were considered to be ‘consultant’ procedures, with all others being undertaken by trainees. Results: No significant patient demographical differences, or differences in fracture type were identified for the two cohorts. Clinical outcomes for the two cohorts were likewise similar at 6 months although there was a suggestion that pain, pinch and grip strength were marginally better in the Periloc group although this was not statistically significant. In the Synthes VLP cohort, 32 operations were undertaken by consultants and 33 by trainees, compared with 9 and 27 operations being undertaken by consultants and trainees respectively in the Periloc group. Although there was a tendency for the more difficult fractures to be operated upon by consultants, especially in the earlier cohort, trainees were left to deal with many of the more complex injuries in the Periloc cohort. The incidence of minor complications requiring further surgery (all relating to prominent metalwork) was also low in both groups (7 in the first group and 2 in the second group) with all but one of the index operations having been performed by a trainee. Discussion: Despite the complexity of many distal radial fractures, VLP treatment of distal radial fractures has become a common place procedure that, in our unit, are frequently left to experienced trainees to operate upon without supervision. Our prospectively cohort studies clearly show that, over time, experienced trainees obtain clinical results that are similar to their consultant colleagues with respect to clinical outcome and incidence of complications. Conclusions: As our unit’s experience of treating patients with distal radial fractures with VLPs has grown, experienced trainees appear to obtain clinical results that are similar to consultants

Aims

The primary aim of this study was to determine the rates of return to work (RTW) and sport (RTS) following a humeral shaft fracture. The secondary aim was to identify factors independently associated with failure to RTW or RTS.
