Introduction

The reverse obliquity fractures of the proximal femur are anatomically and mechanically different from most intertrochanteric fractures. These fractures are complex and very difficult to treat. To evaluate the results of the treatment of reverse obliquity intertrochanteric fractures with cephalomedullary nails.

Materials and Methods

Between 2005 and 2009, 1179 extracapsular fractures of the proximal femur were treated at our institution. Retrospective review of these x-rays identified 59 patients with reverse obliquity fracture pattern. We analysed our results of cephalomedullary nailing of these complex fractures and evaluated factors responsible for failure of fixation.

Introduction

Failed operated intertrochanteric fractures (with screw cutout, joint penetration, varus collapse, nonunion, or femoral head avascular necrosis) pose treatment dilemmas. The ideal approach is re-osteosynthesis with autologous bone grafting. When the femoral head is unsalvageable, conversion to a prosthetic hip replacement is necessary.

Materials/Methods

Thirty-seven patients with failed dynamic hip screw fixation (and unsalvageable femoral heads) were treated with cementless hip arthroplasty (13 underwent Bipolar Arthroplasty, 24 had Total Hip Arthroplasty) over a 5-year period (Dec 2005 to Nov 2010). Seven needed a modified trochanteric split, and the rest were managed by standard anterolateral approach. Abductor mechanism was reconstructed using strong nonabsorbable sutures (ethibond 5) or stainless steel wires. The calcar was partially reconstructed using remnant femoral head and cerclage wiring in a few cases.

Introduction

We conducted an audit on hip fractures to analyse the accuracy of coding and payment by results in our institution.

Materials/Methods

The initial audits analysed hip fracture over a period of four months at two different trusts. Case notes were reviewed to extract data regarding diagnosis, comorbidities and operative procedures. The findings were compared with the data from clinical coding department and difference in the tariff was analysed. A re-audit was performed at Trust B after implementation of changes to assess improvement.

Introduction

To compare the union rates and post-operative mobility of antegrade intramedullary nailing of osteoporotic traumatic supracondylar femoral fractures (AO classification A to C2) with those of plating.

Materials/Methods

We studied any traumatic intra or extra-articular supracondylar femoral fracture from 2005–2010. Patients were either admitted directly to our level 1 trauma centre or were referred from another hospital. Nineteen patients were identified, consisting of primarily fixation with five antegrade nails and fourteen plates. We defined osteoporotic bone as being present in anyone over sixty years old or who had a clinical diagnosis. One nail and six plates were excluded due to young age or fracture severity. This left four nails, six less invasive stabilisation system plates and two dynamic condylar screw plates. Both groups were comparable with respect to age, sex and AO fracture classification.

Introduction

We retrospectively evaluated our five years' experience in using Expandable Fixion nail system in tibial diaphyseal fractures.

Materials/Methods

Eighteen cases with closed tibial diaphyseal fracture were identified between January 2006 and January 2011, all treated successfully with Fixion intramedullary nail as a primary osteosynthesis device.

Introduction

Clavicle fractures can cause pain and functional impairment if not managed appropriately. This paper evaluates the prevalence of clavicular fractures, estimates number of cases requiring operative treatment, whether removal of implant is a frequent necessity and compares the final functional outcome of the operative and non-operative group.

Materials/Methods

Between November 2005 and November 2007 patients with clavicular fractures were eligible for participation. Patients below 18 years of age, and pathological fractures were excluded. Operative versus non-operative treatment, radiographic classification (Allman system), complications, implant removal, and functional outcome using the University of California Los Angeles (UCLA) shoulder scores were documented and analysed.

Introduction

Treatment for distal third shaft fractures of humerus is very challenging. They are commonly treated with plating. Plating has complications of iatrogenic radial nerve palsy. We report our case series of distal third fractures of humerus treated with retrograde Halder Humeral Nail.

Materials/Methods

Since 1994 to 2010 we have 576 fractures of humerus treated with retrograde Halder Humeral nail. Of these 45 fractures were distal third of humerus. Average age of patients at the time of surgery was 30.4 years (Range 15–82 years, Median 33 years). Of 45 patients 26 were females and 19 males. Three out of 45 had non union at the time of presentation. All patients were followed until clinical and radiological signs of union. One patient was lost to follow-up.

Introduction

To investigate if the gap index measured in the follow-up X-rays predicts the reduction of swelling in the plaster cast thereby increasing the risk of re-displacement of fracture treated by manipulation alone.

Materials/Methods

We selected for this study a cohort of children who presented with a traumatic displaced fracture of distal radius at the junction of metaphysis and diaphysis who were treated with manipulation alone. This cohort was chosen because of the high risk of re-displacement following closed manipulation of this unstable fracture and to maintain uniformity of the fracture type. Cast index and Gap index was measured in the intra-operative radiograph and at two-weeks to note the change in these indices. Gap index which is measured by summing radial and ulnar translation/inner diameter of cast in the AP X-ray and similar translation on the lateral x-ray/inner diameter of cast, with a measure of <0.15 considered to be a satisfactory cast.

Introduction

Transportal technique of femoral drilling allows the femoral tunnel to be placed in anatomic location. The study was conducted to evaluate the orientation of ACL graft performed by two different techniques and compared to orientation of native ACL.

Materials/Methods

50 patients (Group A) underwent ACL reconstruction with transtibial technique using transfix on the femoral side and 30 patients (Group B) underwent ACL reconstruction with transportal technique using endobutton. We used quadrupled hamstrings graft and tibial fixation was achieved with bio-absorbable screws. All patients were evaluated with 3 Tesla MRI at 6 months post-operatively and femoral tunnel angle in coronal plane (FTA), tibial tunnel angle (TTA) in sagittal plane, graft angle in coronal plane (GA coronal), graft angle in sagittal plane (GA sagittal), and graft- Blumensaat line angle (GBLA) were measured. A control group of patients (Group C, n=50)was also included to evaluate the orientation of native ACL.

Introduction

The transtibial approach is widely used for femoral tunnel positioning in ACL reconstruction. Controversy exists over the superiority of this approach over others. Few studies reflected on the reproducibility rates of the femoral tunnel position in relation to the approach used.

Methods

We reviewed AP and Lat X-ray radiographs post isolated ACL reconstruction for 180 patients for femoral tunnel position, tibial tunnel position and graft inclination angle. All patients had their operations performed by one surgeon in one hospital between March 2006 and Sep 2010. All operations were performed using one standard technique using transtibial approach for femoral tunnel positioning. Two orthopaedic fellows, with similar experiences, reviewed blinded radiographs. A second reading was done 8 weeks later. Pearson inter-observer and intra-observer correlation analyses were done using SPSS. Mean age was 29 years (range 16–54).

Introduction

Anatomical reconstruction of the Anterior Cruciate Ligament (ACL) reconstruction has been shown to be desirable and improve patient outcome. The posterior border of the anterior horn of the lateral meniscus (AHLM) is an easily identifiable arthroscopic landmark, which could guide anatomic tibial tunnel position in the sagital plane. The aim of the study was to establish the relationship between the posterior border of AHLM and the centre of the ACL foot print to facilitate anatomical tibial tunnel placement.

Materials/Methods

We analysed 100 knee MRI scans where there was no ACL or lateral meniscal injury. We measured the distance between the posterior border of the AHLM and the midpoint of the tibial ACL footprint in the sagital plane. The measurements were repeated 2 weeks later for intra-observer reliability.

Introduction

Meniscus deficiency leads to the development of early arthritis. Total knee replacement may be the only available treatment option in certain situations. However it is generally best avoided in young patients. We hypothesized that a combination of the two procedures, Allograft Meniscal Transplantation (AMT) and Autologous Chondrocyte Implantation (ACI) would be a solution to treat bone-on-bone arthritis in meniscal deficient knees and postpone the need for a total knee replacement (TKR).

Materials/Methods

12 consecutive patients who underwent both ACI and AMT between 1998 and 2005 were followed up prospectively. The patients were assessed by a self-assessed Lysholm score prior to the procedure and yearly thereafter. All operations were performed by the senior author (JBR). ACI procedure was performed according to the standard technique. Frozen meniscal allograft with bone plugs at either ends secured by sutures in the bone tunnels. Post operatively all patients underwent a strict Oscell Rehabilitation protocol. A repeat procedure or progression to a TKR was taken as a failure.

Introduction

Traditionally the use of small diameter femoral head (22mm) with the posterior approach has been perceived as an increased risk of dislocation. We present this prospective study of 400 consecutive total hip replacements performed using a 22mm femoral head and the posterior approach.

Materials/Methods

Between March 2000 and November 2005 364 patients underwent 400 total hip replacements with a small diameter 22mm head under the care of four different consultants, using a standard posterior approach. All of the femoral implants were cemented using modular C-stems (Depuy Ltd.) and all of the acetabular components were cemented flanged monobloc all-polyethylene components with long posterior wall with a third generation cementing technique. A standard posterior approach was used in all cases, with direct repair of the capsule and short external rotators.

Introduction

Recurrent dislocation after hip arthroplasty is a difficult problem. The purpose of the present study was to evaluate the results with the use of a constrained cup for treatment for instability after hip arthroplasty.

Materials/Method

A prospective database of 30 patients who underwent revision hip surgery for dislocation of hip arthroplasty was kept with the surgeries taking place between Nov 2005 to Feb 2010.

Introduction

Success of total hip replacement (THR) is closely linked to positioning of the acetabular component. Malalignment increases complication rates. Our aim was to describe the anteversion and inclination of the inherent acetabulum in arthritic hips and identify the number that fall out with the ‘safe zone’ of acetabular position described by Lewinnek et al. (anteversion 15±10 degrees; inclination 40±10 degrees).

Materials/Methods

A series of 65 hips undergoing non-image based computer navigated THR for Osteoarthritis were investigated. Anteversion and inclination was measured with the help of cup trials fixed with computer trackers aligned in orientation of the natural acetabulum. The acetabular inclination in all hips was measured on pre-operative digital radiographs.

Introduction

Negative remodelling of the femoral cortex in the form of calcar resorption due to stress shielding and cortical hypertrophy at the level of the tip of the implant, due to distal load transfer, is frequently noted following cemented total hip replacement, most commonly with composite beam implants, but also with polished double tapers. The C-stem polished femoral component was designed with a third taper running from lateral to medial across and along the entire length of the implant, with the aim of achieving more proximal and therefore more natural loading of the femur. The hoop stresses generated in the cement mantle are transferred to the proximal bone starting at the calcar, which should theoretically minimise stress-shielding and calcar resorption, as well as reducing distal load transfer, as signified by the development of distal femoral cortical hypertrophy.

Materials/Methods

We present the results of a consecutive series of 500 total hip replacements performed between March 2000 and December 2005 at a single institution, using a standard surgical technique and third generation cementing with Palacos-R antibiotic loaded cement. Data was collected prospectively and the patients remain under annual follow-up.

500 arthroplasties were performed on 455 patients with an average age of 68.3 years (23–92). 77 patients have died (73 arthroplasties) and the average duration of follow-up for the entire series is 81 months (52–124).

Introduction

Reverse total shoulder replacement is performed for the treatment of rotator cuff arthropathy, massive irreparable cuff tears and failed shoulder hemiarthroplasty with irreparable rotator cuff tears. The aim of this study was to assess the clinical and radiological outcome of single surgeon series of Equinoxe® reverse total shoulder replacement at a district general hospital.

Materials/Methods

Consecutive patients who underwent Equinoxe® reverse total shoulder replacement at our unit from Jun 2008 to Dec 2010 were retrospectively reviewed. Indications for surgery, complications and radiological outcomes were assessed. Oxford shoulder score was used to assess the functional outcome.

Introduction

The purpose of this study was to assess the rate of revision subacromial decompression and identify different pathologies.

Materials/Methods

We analysed the patients who underwent Revision Arthroscopic Subacromial decompression from our prospective database of shoulder patients. Between April 2003 and Dec 2010, 797 patients underwent arthroscopic subacromial decompression. Patients who underwent any other procedure i.e. biceps tenotomy, capsular release, cuff repair were excluded from the study. Of these, 37 underwent a revision subacromial decompression (Revision rate 4.6%). The indication for revision procedure was persistent pain or restricted movements not responding to physiotherapy and injections.

Introduction

Whiplash injury following rear shunt Road traffic accident (RTA) has been associated with impingement syndrome of shoulder. However, the results of arthroscopic subacromial decompression (ASAD) for this group of patients have never been compared to the non accident group. In our study we aim to compare the results of ASAD in these patients to a group who did not sustain whiplash injury.

Materials/Methods

Thirteen patients with impingement syndrome following rear shunt RTA were followed up (2004–09). After failed conservative management for at least 6 months ASAD was performed. This group was compared with a control group (not involved in an RTA) of 13 consecutive patients (age and sex matched). All patients were assessed with Oxford shoulder score preoperatively and twice post operatively (within 3 months and at one year).

Introduction

A prospective study was done using Kirschner (K) wires to internally fix capitellum fractures and its results were analysed.

Materials/Methods

Since 1989, unstable displaced 17 capitellum fractures were anatomically reduced and internally fixed by inserting K wires in coronal plane from the capitellum into trochlea. The lateral end of wires were bent in form of a staple behind the fracture plane and anchored into the lateral humeral condyle with pre-drilled holes. Additional screws were used in 2 cases to stabilise the lateral pillar comminution. The capitellum was exposed with a limited modified lateral elbow approach between anconeus and extensor carpi ulnaris. The capsule was reflected anteriorly to expose the capitellum and trochlea. The deeper dissection was limited anterior to lateral collateral ligament (LCL) keeping it intact. The capitellum fragment was reposition under the radial head and anatomically reduced by full flexion of elbow and then internally fixed. Total 17 patients (7 males and 10 females) with average ages 34.8 years(14 to 75) had fractures, Type I: (Hans Steinthal #) 12, Type II: (Kocher Lorez #) 1, and Type III: (Broberg and Morrey #) 4. Post-operatively the patients were not given any immobilisation and were mobilised immediately.

Introduction

Management of painful scarring of a nerve after surgery or trauma is challenging. Wrapping with a vein or adhesion barriers such as silicone have been reported with some success. This is a retrospective review of application of a xenograft collagen wrap around a peripheral nerve following neurolysis. There is no report in English literature of use of a collagen wrap for this purpose.

Materials/Methods

12 patients underwent use of the Neuragen™ bovine collagen nerve conduit or NeuraWrap™ (Integra Life Sciences, Plainsboro, NJ) over a 6 year period. The causes were, scarring after carpal tunnel (n=5) or cubital tunnel release (n=3) or partial nerve injury (n=4, radial, median, dorsal ulnar, digital nerves). Follow up ranged from 6–12 months. Outcome was assessed by VAS or functional improvement.

Introduction

There are conflicting reports about the efficacy of injection to the thumb carpometacarpal joint (CMCJ) for osteoarthritis (OA). The accuracy of joint injection without radiological control is unclear. We investigated the accuracy of blind injection and recorded their immediate and short term efficacy.

Materials/Methods

We injected 25 consecutive patients between March 2010-January 2011. The CMCJ was palpated, manually distracted and a 23 gauze needle introduced blindly. Image intensifier was then used to visualize and redirect needle if necessary. Radio-opaque dye was injected to confirm intra-articular placement. We recorded patient demographics, number of attempts required for correct needle placement, pre and 10 minutes post-injection visual analogue scale (VAS) pain score, and Nelson Score (NS)before and six weeks after injection. NS is a validated thumb CMCJ specific patient administered questionnaire.

Introduction

The distal radius is the most frequently fractured bone in the forearm with an annual fracture incidence in the UK of about 9–37 in 10,000. Restoration of normal anatomy is an important factor that dictates the final functional outcome. A number of operative options are available, including Kirschner wiring, bridging or non-bridging external fixation and open reduction and internal fixation by means of dorsal, radial or volar plates. We designed this study to analyse the clinical and radiological outcome of distal radial fracture fixation using volar plating.

Materials/Methods

Thirty-seven patients with distal radius fractures undergoing open reduction and internal fixation using volar plates were included. Tilt of the fractured distal radial fragment was recorded from the initial radiograph and classification of fractures was done using the Orthopaedic Trauma Association system. The QuickDASH questionnaire was used for evaluation of symptomatic and functional outcome six months to one year after surgery. The radiological outcome was assessed using measurements of radial inclination, ulnar variance and volar tilt. Of the thirty-seven patients, 13 were male and 24 were female. The mean age was 55.6 years (range 18–87 years). According to the AO classification, there were 8 cases each of C2 and C3 fractures, 6 cases of C1 fractures and 3 cases each of class A2, A3, B1 and B3 fractures. There were 2 patients with class B2 fracture.

Introduction

Local recurrence of tumours along the biopsy tract is a known complication of percutaneous closed needle biopsy. Correct surgical management requires preoperative identification and excision of the biopsy tract at time of surgery. These tracts become increasingly difficult to identify with time, leading to risk of inadequate excision of the biopsy tract and recurrence of the tumour at the biopsy site.

Materials/Methods

In a prospective study conducted at our institution, 22 of the 45 patients with musculoskeletal tumours (49%) had unidentifiable biopsy sites, with a mean duration between biopsy and definite surgery being 98 days (range 13–164 days). We concluded that identification of the biopsy site was more difficult after 50 days. Radiotherapy related scar formation and the longer time duration between biopsy and definite surgery in patients requiring neoadjuvant therapy made identification more unlikely. Consequently, all patients received India ink skin tattoo to mark the biopsy site at the time of the needle biopsy. 56 patients were then prospectively reviewed on the day of surgery to identify the biopsy site.

Introduction

Ankle fractures are one of the commonest orthopaedic injuries. A substantial proportion of these are treated non-operatively at outpatient clinics with cast immobilization. Recent literature and NICE guidelines suggest risk assessment and provision of appropriate thromboembolism in patients with lower limb casts. We conducted this survey to assess the current practice in UK regarding thromboembolism prophylaxis in these patients.

Materials/Methods

A telephonic survey was carried out on junior doctors within orthopaedic departments of 56 hospitals across the UK. A questionnaire was completed regarding venous thromboembolism risk assessment, prophylaxis and hospital guidelines etc.

Introduction

‘VTE disease is the new MRSA’, with much attention received in the media and the political world. Following the 2010 NICE guidelines all patients admitted to hospital should have VTE prophylaxis considered and a formal VTE risk assessment done with documentation and review in a 24 hour period. We carried out a completed audit cycle to identify our adherence to these guidelines and introduced a novel method to ensure compliance.

Materials/Methods

An audit of 400 patients admitted to the orthopaedic department was carried out with review of case notes. Three key parameters were investigated: Firstly the compliance of carrying out a risk assessment for VTE disease with correct documentation, secondly investigating how many patients got re-assessed in 24 hours and finally if patients received appropriate VTE prophylaxis. The data was re-audited following the introduction of a new drug chart with a box section for VTE risk assessment and prophylaxis on the chart itself.

Introduction

Epidural steroid injection is an established treatment modality for intervertebral disc prolapse. It is a low-risk alternative to surgical intervention in some patients for whom noninvasive treatment has failed. Caudal epidural steroid injection is one of the most widely used methods for pain relief. The aim of this study was to determine the significance of same dose in different volume of caudal epidural steroid injection in the treatment of lumbar degenerative disc disease.

Material/Methods

Prospective study was conducted during 2007 to 2009. 100 Patients were randomized in to two groups, of which 50 % (group A) received 4 ml of steroid with isotonic saline and remaining 50 % (group B) received 12 ml. Injection was given in prone position through a 22-G needle in to the epidural space through the sacral hiatus. The average follow-up was 18 months. Outcomes scores included the SF-36, Oswestry disability index and pain VAS and were recorded in the pre and post injection periods.

Introduction

Microdiscectomies and microdecompressions are traditionally defined as procedures performed with a small incision using magnification. There are no studies in the literature comparing the magnification techniques used in these operations. We compared magnifying loupes and microscopes as the senior author was trained with both instruments and was equally comfortable using both.

Materials/Methods

This is a retrospective comparative study involving 51 consecutive patients in group A (loupes) and same number in group B (microscope). The study included all patients who had single level lumbar microdiscectomy or decompression in the period from the 11th of January 2009 to the 6th of April 2010. To avoid any bias, only patients who failed to attend their follow ups were excluded from the study. The senior author operated on all patients. We noted intra-operative and post-operative complications, further interventions, length of surgery and length of hospital stay. We conducted a telephone questionnaire to collect visual analysis score for pre-op and post-op pain and functional status to calculate Macnab's functional status score. 78 patients (75.6%) answered the questionnaire, 39 patients from each group. There was 1 dural leak in group A.1 patient had discitis in the group A and 1 patient had superficial infection in group B. 4 patients in group A and 1 patient in group B had residual pain requiring intervention. The average length of surgery was one hour and five minutes and one hour and eleven minutes, respectively. Mean hospital stay was 1.43 days and 1.78 days, respectively. The data in the group B was skewed due to one patient who stayed for 9 days after surgery. 25 patients (49%) in group A and 36 patients (70.5%) in group B returned to normal pre-prolapse function and physical activity within 3 months.

Introduction

Appropriate consenting is part of good medical practice and is a medico-legal necessity for invasive procedures. The BOA recently created generic consent forms covering the relevant complications for orthopaedic procedures, thus providing a standard for all orthopaedic consent. This study aims to assess the quality of consent in orthopaedic practice.

Materials/Methods

The most common elective and trauma procedures were identified over a one year period and consent forms for all patients undergoing these procedures were assessed against BOA ortho-consent forms. Data was compiled from elective total hip replacements (THR) and trauma ankle open reduction and internal fixations (ORIF), and analysed in excel.

Introduction

Hind foot Charcot deformity is a disastrous complication of diabetic neuropathy and can lead to instability, ulceration and major amputation. The treatment of these patients is controversial. Internal stabilization and/or external fixation have demonstrated variable results of limb salvage and some authorities thus advise patients to undergo elective major amputation. However, we report a series of 9 diabetic patients with severe hind foot deformity complicated by ulceration in 5/9, who underwent acute corrective internal fixation with successful correction of deformity, healing of ulceration in 4/5 patients and limb salvage in all cases.

Methods

We treated 9 diabetic patients attending a multidisciplinary diabetic/orthopaedic foot clinic with progressive severe Charcot hind foot deformity despite treatment with total contact casting, 5 with predominant varus deformity and 2 with valgus deformity and 2 with unstable ankle joints. Five patients had developed secondary ulceration. All patients underwent corrective hind foot fusion with tibiotalo-calcaneal arthrodesis using a retrograde intra-medullary nail fixation and screws and bone grafting. One patient also with fixed plano-valgus deformity of the foot underwent a corrective mid-foot reconstruction.

Introduction

Achilles tendinosis results from a chronic degenerative process within the tendon. Topaz micro-debridement aims to restore the degenerate micro-architecture within the tendon reducing painful symptoms experienced by patients. Topaz micro-debridement has been used to successfully treat upper limb tendinopathies but its application to tendinopathies of the foot and ankle is relatively new. This study aims to assess the functional outcomes following topaz radiofrequency micro-debridement for Achilles tendinosis.

Materials/Methods

All cases of topaz micro-debridement for Achilles tendinosis were identified from hospital records spanning a five year period. VISA-A assessment questionnaires were sent to these patients to assess the patients functional status pre and post-surgery. Patients were asked to comment on their overall satisfaction and to report any complications they had experienced. Eight responses were received and included in analysis. Hospital records and imaging results were investigated for those that responded.

Introduction

The wrist arthroscopy has been performed since 1979. With the advances in technology and surgical expertise, wrist arthroscopy has become third commonest procedure after knee and shoulder joint. Wrist arthroscopy has become a gold standard for diagnosing TFCC pathologies and other intercarpal disorders. Our aim was to compare the clinical, MRI and arthroscopic findings while treating various wrist pathologies.

Materials/Method

In retrospective trial, 30 patients (19 male and 11 female) with clinical evidence of wrist lesions were evaluated with MRI followed by wrist arthroscopy. The mean age of the patients at the time of outpatient appointment was 44 years with an average waiting time of 6.6 months. Inclusion criteria: all patients undergoing wrist surgery. Exclusion criteria: septic arthritis, acute distal radius fractures. Kappa analysis was used to compare the three methods of wrist pathology assessment. The total 30 patients were assessed for clinical findings, MRI report and corresponding arthroscopic findings.
