Introduction

Intramedullary lengthening devices have been in use in older children with closed /open growth plates with good success. This study aims to present the early experience of the FITBONE nail since withdrawal of the PRECICE nail.

Materials & Methods

Retrospective analysis of both antegrade and retrograde techniques were utilized. Only patients where union was achieved and full weight bearing commenced were included. The complication rate, length gained, distraction index, weight bearing index (WBI) as well as mechanical axes were analysed.

Introduction

Motorised intramedullary lengthening nails are considered more expensive than external fixators for limb lengthening. This research aims to compare the cost of femoral lengthening in children using the PRECICE magnetic lengthening nail with external fixation

Materials and Methods

Patients: Retrospective analysis of 50 children who underwent femoral lengthening. One group included patients who were treated with PRECICE lengthening nails, the other group included patients who had lengthening with external fixation. Each group included 25 patients aged between 11–17 years. The patients in both groups were matched for age. Cost analysis was performed following micro-costing and analysis of the used resources during the different phases of the treatments.

Introduction

The purpose of this research is to compare the quality of life in children during gradual deformity correction using external fixators with intramedullary lengthening nails.

Materials and Methods

Prospective analysis of children during lower limb lengthening. Group A included children who had external fixation, patients in group B had lengthening nails. Patients in each group were followed up during their limb reconstruction. CHU-9D and EQ-5DY instruments were used to measure quality of life at fixed intervals. The first assessment was during the distraction phase (1 month postop.), the second was during the early consolidation phase (3 months postop.) and the final one was late consolidation phase (6–9 months depends on the frame time)

Introduction

Torsional malalignment syndrome (TMS) is a unique combination of rotational deformities in the lower limb, often leading to severe patellofemoral joint pain and disability. Surgical management of this condition usually consists of two osteotomies in each affected limb, with simultaneous correction of both femoral anteversion and external tibial torsion. However, we believe that a single supratubercular osteotomy followed by tibial derotation with the Taylor Spatial Frame (TSF) can be used to provide a significant improvement in both appearance and function.

Materials and Methods

This is a retrospective case analysis in which we will be reviewing 16 osteotomies performed by one surgeon between 2006 and 2017. The study includes 11 patients with a mean age of 16.7 ± 0.8 years. Pre and post-operatively, patients were fully evaluated through history and physical examination, and CT rotational profiling. Statistical analyses were performed in order to determine whether or not any observed clinical or cosmetic improvements were statistically significant.

Introduction

Recurrence in CTEV is not uncommon and as the child becomes older the foot in question is often stiffer and less amenable to the more traditional serial casting Ponseti method. Treatment of these recurrent CTEV feet with external fixators has been previously documented. We aim to present the Sheffield technique of an external circular frame with adjunctive hindfoot and midfoot osteotomies to correct relapsed CTEV and their associated Roye (outcome) scores.

Materials and Methods

Retrospective analysis of patient records from 1999 to 2019 were performed for those undergoing frame correction of CTEV. Patients were included if there was adjunctive foot osteotomies in the setting of CTEV frame correction and willingness to partake in retrospective Roye outcome scoring. The Roye score was sent out in the mail to parents asking for scoring of the current level of symptoms.

Aims

Within the UK, around 70,000 patients suffer neck of femur (NOF) fractures annually. Patients presenting with this injury are often frail, leading to increased morbidity and a 30-day mortality rate of 6.1%. COVID-19 infection has a broad spectrum of clinical presentations with the elderly, and those with pre-existing comorbidities are at a higher risk of severe respiratory compromise and death. Further increased risk has been observed in the postoperative period. The aim of this study was to assess the impact of COVID-19 infection on the complication and mortality rates of NOF fracture patients.

Methods

All NOF fracture patients presenting between March 2020 and May 2020 were included. Patients were divided into two subgroup: those with or without clinical and/or laboratory diagnosis of COVID-19. Data were collected on patient demographics, pattern of injury, complications, length of stay, and mortality.

The purpose of the study was to investigate the incidence of surgical site infection following elective paediatric orthopaedic surgery.

A pro forma adopted from a pilot study was filled out preoperatively for each elective operation performed during the study period. Each patient was then followed up for six weeks postoperatively to record any SSI that developed. Data collected included patient demographics, type of operation, grade of Surgeon, type of procedure, wound length, skin preparations, use of tourniquet, any antibiotic prophylaxis and length of operation.

This study collated data on 334 operations with 410 procedural sites over a six month period. Infection were recorded in 19 sites equivalent to a SSI rate of 4.63%. None of the patients developed long-term complications.

The mean age of the participants in the study was 11 years (range 0.5 to 17 years), 57% were males and 43% were females.

The infection were detected between 1 and 38 days after surgery. The outcome was not compromised in any of the patients as none of them required long-term treatment. Statistical analysis was undertaken.

The study proves that the surgical site infection after elective paediatric orthopaedic surgery is low and serve as a bases for consenting patients for surgery.

We report the radiological outcomes, and short-term clinical results, of 47 periacetabular osteotomies undertaken through both the traditional bikini incision, and a minimally invasive approach.

47 periacetabular osteotomies have been undertaken in 45 patients, by the senior author, between 2005 and 2013. There were 10 male and 35 female patients. The mean age at operation was 28.2 years. Since 2010 surgery has been performed through a 7-cm skin incision (31 hips), an incision coined as minimally invasive by Søballe et al when they described their trans-sartorial approach for acetabular surgery. Clinical data was collected prospectively; primary outcome measures included the young adult hip score and the hip disability and osteoarthritis outcome score. Pre- and post-operative radiographs were analysed for achieved acetabular reorientation.

At the time of follow-up the median young adult hip score had improved significantly from pre-operative values. Mean scores were 35.4 pre-operatively, and 64.25 post-operatively. Improvement in the anterior and lateral centre-edge angle was 32 and 32.9 degrees respectively through a traditional incision, and 27.1 and 30 degrees through the minimally invasive approach (p>0.05). No major complications occurred in any patient. Four patients complained of lateral cutaneous nerve hypoaesthesia, in two patients there was delayed union of the pubic osteotomy and in one non-union. Two patients have gone on to total hip replacement.

The minimally invasive approach is safe and allows for accurate reorientation of the acetabulum whilst minimizing tissue damage. The scar is cosmetically appealing to patients, especially the predominantly female group treated with this condition. We did not see the evidence of reduced surgical stay that has been reported by other groups utilizing a minimally invasive approach.

Level of evidence: II

The Pelvic Support Osteotomy (PSO) or Ilizarov Hip Reconstruction(IHR) is well described for the treatment of septic sequelae of infancy. The purpose of this study was to clinically, functionally and radiographically assess our short-term results of this procedure.

25 patients (16 boys, 9 girls) who had undergone a IHR using the Ilizarov/TSF construct over a period of 10 years for a variety of pathologies were reviewed. The mean age at surgery was 15 years 4 months. The pre-operative diagnoses were SCFE(10), hip sepsis (6), DDH (6) and Perthes (3). All had significant leg length discrepancies, 16 had a painful stiff hip, 6 had a painful mobile hip and 3 had a painless unstable hip. At surgery, a mean measured proximal valgus angle of 51° and a mean extension angle of 15° was achieved. Distal femoral lengthening averaged 4.2 cm and distal varus correction was a mean of 8°. The mean fixator time was 173 days.

At a mean of 2 years and 7 months follow-up the lower-extremity length discrepancy had improved from a mean of 5.6 cm apparent shortening to 2.3 cm. Trendelenberg sign was eliminated in 18/25 cases. Improvements in range of hip movements and gait parameters were observed. Stance time asymmetry, step length asymmetry, pelvic dip and trunk lurch improved significantly. One patient had conversion to a total hip replacement after 7 years, 4 patients required re-do PSO due to remodelling of the proximal osteotomies, two had heterotopic ossification and two had significant knee stiffness due to lack of compliance.

The early results of IHR are encouraging to equalise limb lengths, negate trendelenburg gait, provide a mobile hip with a reasonable axis and the possibility of conversion to THR in the future if needed. Complications need to be anticipated and the effects of remodelling and maintaining adequate knee range of motion must be emphasised.

Aim

The use of intraoperative cell salvage as a tool for reducing allogenic transfusion has been demonstrated in pelvic osteotomies. The aims of this audit were to identify any problems or complications with cell salvage, reduction in allogenic transfusion and identify procedures that would benefit.

Methods

The use of cell salvage and allogenic transfusions were prospectively recorded over a 27-month period for all those who had major non spinal surgery looking at whether cell-salvage reduced allogenic transfusions and where cell salvage was used it was matched to procedure, diagnosis and age with cases where it was not used over the same time period.

Aim

To study the results of using recombinant human bone morphogenic protein-2 (rhBMP-2) to achieve bone union in children with complex orthopaedic problems including skeletal dysplasia, congenital limb deficiencies and complex trauma.

Materials & Methods

Between November 2006 to April 2010, rhBMP-2 was used to achieve bone healing in a total of 19 children. The indications were delayed union or non-union in 16 long bones where previous surgeries had failed and 4 posterior spinal fusions. All children had underlying complex orthopaedic problems predisposing them to delayed bone healing. The average age at the time of surgery was 13 years and 8 months (Range: From 4 years to 19 years and 4 months). There were 7 boys and 12 girls.

The purpose of this study was to determine the oblique plane deformity in slipped upper femoral epiphysis.

A retrospective radiographic review was undertaken in patients admitted with a slipped upper femoral epiphysis between March 2008 and October 2010. Patients in whom a CT scan had been performed in addition to plain radiographs were assessed further. Angular deformity in the coronal and sagittal planes were measured by the angle formed between the femoral neck and a line perpendicular to the physis on the AP pelvic radiograph and the axial CT scan respectively. The magnitude and direction of the resultant deformity was defined in the oblique plane. Additional demographic data (gender, age, side, procedure and complications) was collected.

Seven girls, average age of 12 (range 10 – 13) and 6 boys, average age of 13 (range 10 – 15) were identified. The slip was bilateral in 2, left sided in 6 and right sided in 5 cases. Two patients were pinned in situ, 8 had surgical dislocation performed to facilitate reduction prior to pinning and 3 patients had secondary procedures performed following in situ pinning. The average angulation in the oblique posteroinferior plane (25 degrees) was less than in the coronal (30 degrees) and the sagittal planes (62 degrees). The average magnitude was 67mm (range 31 – 88).

CT is useful adjunct particularly when a frog legged lateral view is not possible because of pain or the fear of further displacement. Determination of the deformity in the oblique plane may aid in positioning of the screw during in situ pinning and may be helpful in identifying patients in whom pinning maybe difficult.

Introduction: Plastic deformation of the regenerate bone is a complication noted soon after limb lengthening. However, less is known about the factors responsible for the development of plastic deformation.

Materials and Methods: Retrospective analysis of 35 X-rays of achondroplast children who had limb lengthening were reviewed. The study compared Monofocal Vs Bifocal and Long lengthenings(> 10 cms) Vs modest lengthenings(≤ 10 cms) of tibial lengthening. Other parameters included in study were Bone healing Index, total length gained and sagittal and coronal axial deformities. There were 20 females and 15 males, 21 long lengthenings and 14 modest lengthenings in the study. The joint orientation and diaphyseal angles(antero-posterior and lateral X-ray views) was used for the measurement of plastic deformation of the regenerate bone.

Results: The mean age at operation was 10 years (range; 6–16 years). There were 29 cases of monolateral fixator and 6 of Ilizarov ring fixator, Of which 26 had monofocal lengthening and 9 had bifocal lengthening (34 callotasis and 1 chondrodiastasis). The total average length gained was 10 cms (range; 23–152). The mean bone healing index and external fixation index/time were 41 days and 352 days respectively. Plastic deformation of the regenerate bone was seen in 26 cases in total. 24 out of 29 cases of monolateral fixator (82%) developed plastic deformation. 44%(4/9) of bifocal group and 84%(22/26) of monofocal group showed evidence of plastic deformation. The long lengthenings showed plastic deformation in 85% (18/21) of the cases, whereas only 57%(8/14) of the cases were positive in modest lengthening group. Most of the axial deviation was in the coronal plane in 92% (24/26) and the sagittal plane accounted to only 23%(6/26) requiring surgical correction.

Conclusions: Long lengthenings and monofocal techniques showed more plastic deformation than bifocal and short lengthenings. However, Ilizarov ring fixator with bifocal corticotomy seemed to be promising with less association with the above entity in our recent experience.

Introduction: Patients who develop proximal femoral growth arrest present a typical deformity of short femoral neck, high riding greater trochanter, and caput valgum. This is seen usually seen in Perthes, AVN due to treatment of CDH, and sometimes in epiphyseal dysplasia.

Method: We present a series of 34 cases (34 hips) treated at the above institutes. The cases treated in Berne were prior to 2002. Twenty patients were females. There were 24 patients with Perthes, nine with old healed and treated DDH, and one with epipyhseal dysplasia. All had Trendelenburg or delayed Trendelenburg sign. They had an average shortening of 3.5 cms, and their age range was 14 yrs to 64 yrs. Pre-op assessement was done with plain radiographs, CT scan, and or MRI scan.

Results: Their Merle D’Aubigne score improved from 13 (10 to 15) to 17 (15 to 18) at the latest follow up. Twenty four (70%) had good to excellent result. Five have since undergone a total hip replacement, and five have some pain but can do reasonable amount of activity. The follow-up is 6 years (2 to 13 years). There was one trochanteric non-union, but no cases of AVN.

Discussion: We describe the technique of biomechanically improving the moment arm and muscle length with this procedure. This helps the soft tissues to strengthen, improve force vectors in the correct direct in the hip, perhaps improve the longevity of the joint and also prepare the hip soft tissues for future THR.

Dysplasia of the hip in children, characterised by a shallow acetabulum and a deficient coverage of the femoral head, generally causes altered biomechanics of the hip joint. A kinematic analysis on the individual and comparative spatial movement of the acetabulum with some of the pelvic osteotomy techniques is performed. The osteotomy providing greater correction in most of the parameters potentially leading to greater reduction in loading is the choice of the surgeon.

Adult saw bone hip models have been used. Points of reference have been carefully chosen and data has been obtained using the Polhemus Electromagnetic measuring system before and after the osteotomy. Five techniques (Chiari, Salter, Steel, Tonnis and Ganz) have been performed, parameters like the Centre-edge angle, Sharp’s angle, Acetabular Head index (Femoral head cover), translation and rotation in 3 planes have been analysed.

Results show an improvement in most of the parameters when the above pelvic osteotomies are performed. Centre-Edge angle improved by a mean (in degrees) of 7.4 (Chiari), 9.6(Salter), 16.9(steel), 28.4(Tonnis) and 31.0(Ganz). There has been marked increase in Femoral head cover with mean 24% with Tonnis and Ganz. Significant changes in rotational parameters in all 3 planes were achieved, particularly with Ganz and Tonnis techniques.

Traditionally acetabular dysplasia correction has been assessed in one or two dimensions by plain radiographs and true three dimensional movement of the acetabulum is difficult to assess with simple techniques. This study describes a simple and reproducible method to compare the various pelvic osteotomies and comparative effects these can produce on the kinematics of the hip joint. It is intended to extend this study to include kinetics to compare the forces and stress distribution changes caused by performing the above techniques and a larger study is recommended, based on this technique and the initial trend of results shown.

AIM: The purpose of this prospective study was to asses the outcome of antegrade intramedullary wiring of displaced distal end of fifth metacarpal fracture in skeletally immature. Intramedullary wiring for fracture metacarpals have been well described in the literature. Retrograde wiring for neck of metacarpal fractures have been associated with limitation of extension at metacarpo-phalangeal joint due to involvement of gliding extensor mechanism. Foucher described ‘Bouguet’ osteosynthesis with multiple wires for metacarpal neck fracture which can be technically demanding in small bones of children. We describe an antegrade wiring using a single bent K-wire at the tip for reducing and stabilising displaced metacarpal neck fracture by rotating 180 degree after crossing fracture site, a method similar to Methaizeau technique for stabilisation of displaced radial neck fractures using nancy nail.

METHOD: Between 2000 to 2006 we treated 9 boys with displaced distal end of fifth metacarpal fracture +/− rotational deformity of little finger using above technique. All of them had closed injuries and the indication for surgery was rotatory mal-alignment or fracture angulation more than 40 degrees. The assessment involved a clinical and radiological examination. The mean age was 13 years. The mean follow-up was 15 months.

RESULTS: All fractures healed in anatomical alignment. There was no loss of active or passive movement of the little finger metacarpo-phalangeal joint or weakness of grip strength in any children. All children returned to pre-injury activity level within 4–6 weeks. There were no complications.

CONCLUSION: Early results of treating displaced little finger metacarpal neck fracture in children using antegrade intramedullary wire are encouraging.

Background: Femoroacetabular Impingement is now considered a prearthritic hip mechanism. It frequently occurs in patients with subtle anatomic abnormalities of the acetabulum, “acetabular retroversion”, which is often difficult to detect on standart xrays. Early diagnosis is of utmost importance as surgical intervention in early stages can most likely halt progression of disease. The objective of this study was to assess wether an easily visible anatomic landmark on an anteroposterior (AP) pelvic xray can be used to screen patients with acetabular retroversion.

Methods: The AP pelvic xrays of 1010 patients who were seen at the autors’ institution for a painful hip were reviewed over a 16 year period. Those xrays that did not meet standardized criteria were excluded leaving 149 AP radiographs (298 hips) for analysis. The ‘crossover sign’ (COS), indicative of acetabular retroversion, was recorded for each hip. An easily visible landmark, the prominence of ischial spine (PRIS) into the true pelvis was also recorded and measured. Interobserver and intraobserver variability was assessed.

Results: The presence of the PRIS as diagnostic of acetabular retroversion showed a sensitivity of 91% (95%CI 0.85 to 0.95), a specifity of 98% (95% CI 0.94 to 1.00), a positive predictive value of 98% (95%CI 0.94 to 1.00), a negativ predictive value of 92% (95% CI 0.87 to 0.96). There was good and very good intraobserver and interobserver reliability for measurements of the COS and PRIS, respectively.

Conclusion: There was excellent sensitivity and positive predictive value of the PRIS as a radiographic marker of acetabular retroversion. The rims of the anterior and posterior walls are sometimes not clearly visible, and even if they are, their translation into a reliable interpretation of acetabular retroversion is difficult. The PRIS sign appears as a good visible prominence on the AP radiographs which can’t be easily confused.

We utilized a dry-bone model of the pelvis and proximal femur, set upon transparent Lucite plates with four mounting screws and adjustable struts, allowing measurable and reproducible pelvic tilt and rotation. Our protocol for osteotome placement at each of the osteotomy sites strictly followed the technique described by Ganz. A 30°, 15 mm bifid osteotome was used for imaging at the initial ischial osteotomy at the infracotyloid groove. A 30°, 2 cm straightedge osteotome was placed 4 cm below the pelvic brim to image the retroacetabular osteotomy on the quadrilateral plate. Various osteotome placements were imaged with the C-arm image intensifier to better define the risks of inferior and posterosuperior intraarticular osteotomies at each of these sites, respectively. A 600 osteotome oriented at 500 to the quadrilateral plate was also utilized.

In addition, violation of the inferior quadrant of the joint as well as posterolateral slipping of the osteotome blade along the posterior column, were appreciated on all images of pelvic flexion and rotation. The false-profile view always confirmed the perpendicular orientation of the osteotome blade. The false-profile view allowed for accurate evaluation of the positioning of the 30°, 2-cm straightedge osteotome along the retro-acetabular osteotomy site. In the views obtained, the blade could be seen aligned parallel to the posterior surface of the acetabulum, while respecting the posterosuperior joint space with optimal step-off from the posterior column. False-profile and posterior judet views provided optimal visualization of the 60° osteotome on the quadrilateral plate. In addition, pelvic flexion and rotation did not impact the ability to visualize the inferior margin of the acetabulum in evaluating the potential for creating an inferior intraarticular osteotomy. The results of our study indicate that awareness of the appearance of ideal osteotome placements at each osteotomy site on AP and false profile C-arm image intensification will decrease the incidence of iatrogenic osseous and therefore neurovascular complications reported in the literature and reduce post-operative patient morbidity.

To evaluate the correction of complex congenital deformities of the lower limb by six axes deformity analyses and computer assisted correction using the Taylor TM Spatial Frame (TSF), from 1998 to 2000, the authors performed corrections of multiple congenital deformities in 24 lower limbs in 18 patients. There were 9 males and 9 females. There were a total of 29 bone segments, (8 femurs, 21 tibiae) in the 24 lower limbs that were corrected with application of the TSF. Our series included the following diagnoses and deformities: unknown skeletal dysplasia (2), achondroplasia (3), pseudoa-chondroplasia (1), multiple epiphyseal dysplasia (2), spondyloepiphyseal dysplasia (2), fibular hemimelia (3) tibia hemimelia (1), hypophosphatemic rickets (3), and posteromedial bowed tibia (1).

The mean age of the patients was 15.4 years (range 0.5 to 35 years). The mean frame time until correction was 20.1 weeks (range 9 to 49 weeks). The mean follow up was 2.4 years (range 2 to 3.4 years). The apex of the deformity was directed posteromedial in 7, anterolateral in 6, medial in 5 and anteromedial in 5 patients. The mean coronal and sagittal plane deformities were 14.60 (range −230 to 400) and 70 (range, −400 to 280), respectively. The average magnitude of the deformity was 21.70 (range 90 to 470), and the plane of the deformity to the coronal plane was −23.30 (range −800 to 400). Eight patients had a mean lower extremity shortening of 12.3 mm (range 5 to 50 mm). One patient had 15° of internal rotation. With application of the TSF and the principles of distraction osteogenesis, we were able to reduce the coronal and sagittal plane deformities to 3.10 and 1.40 respectively. The overall mean magnitude of the deformity was decreased to 3.40. Shortening was corrected to an average of 3 mm. We experienced only 4 complications in the 24 limbs (16.7%). Complications in this patient group included one female patient with hypophosphatemic rickets who had residual deformity with significant lateral mechanical axis deviation due to inadequate translation. In addition, there were two superficial pin tract infections and one delayed union.

Computer-assisted six axes deformity planning and TaylorTM Spatial Frame application effectively and safely correct complex congenital and developmental limb deformities and offer significant advantages over the well-established Ilizarov technique.

Thirty-four patients were studied through the whole of the Perthes’ disease in Alder Hey Children’s Hospital, Liverpool. The acetabular changes included osteopaenia of the roof, irregularity of its contour, and decrease in the depth. These changes were proportional to the femoral head involvement. The purpose of the study was to know the effect of the morphological changes of the femoral head on the acetabulum and its outcome.

Radioisotope scans of the hip were examined in fourteen children with unilateral Perthes’ disease and comparison was made with the contralateral hip. These scans showed increased uptake on the lateral part of the acetabulum and no uptake over the avascular part of the femoral head. Average follow-up was ten years and on an average children were followed up from six years to fifteen years of age. Six readings of the measurements of various dimensions of the acetabulum and the femoral head were done. CT scan also showed irregularity in the acetabulum. Statistical tests lead to the conclusion that the decrease in the depth of the acetabulum was secondary to the femoral head involvement and the extent of its dimensional changes affected the final congruity between the femoral head and the acetabulum. Also the remodelling potential of acetabulum decreases as the child grows older. Therefore containment procedures could be done by femoral osteotomy in younger children and acetabular osteotomy may benefit older children.

The role of femoral and acetabular version in correction of dysplasia of the hip has been undereported. Between June 1995 and September 2000, a Bernese periacetabu-lar osteotomy (BPO) was performed in 25 patients (26 hips) by the senior author with an average follow-up of 3.7 years (range 2-5 years). The mean age of the patients (24 female, 1 male) at the time of surgery was 29.4 years (range, 11.5 to 45 years). Only patients with a primary diagnosis of acetabular dysplasia were included in this series.

The average Harris hip score increased from 55.1 (range 34–75) preoperatively to 92.9 (range 72–100) at the latest follow up (p< 0.0001). The mean pre-operative Merle d’Aubign score increased from 13.5 (range 1015) to 17 (range 15–18) at the latest follow up. The mean lateral centre edge angle of Wiberg increased from 13.10 (range 00–200) pre-operatively to 52.60 (range 200-740) at latest follow-up (p< 0.0001). The anterior centre edge angle averaged 10.90 (range 4-170) pre-operatively and improved to 490 (range 210–760) at latest follow-up (p< 0.0001). The Mckibbin instability index is the sum of femoral and acetabular version (normal range 200–500). There were 6 hips with low instability index and 11 hips with high instability index pre-operatively. At the latest follow-up there were only 2 hips with low instability index and there were no patients with a high instability index. Our clinical results showed fi fteen patients with excellent results, eight good results and one fair and one poor results. Thus, overall good to excellent results were obtained in 92% of our patients. It is therefore possible that we had higher success rate in our series than that reported in other series because of the correction of version of the hip in addition to the coronal and sagittal defi ciency of the hip.

The aim of our study was to assess the efficacy and complications of treatment of limb deformities using six axes deformity analysis and the Taylor TM Spatial Frame [TSF]

Between January 1997 and March 2000, we treated 75 lower limbs in 66 patients with deformities. Patients were divided into four groups. The groups were Blount’s disease, congenital deformities, traumatic deformities, and a miscellaneous group. The data was prospectively collected. This was a consecutive series of the first 66 patients treated at our institution with the TSF. Deformity correction using the TSF is done with the aid of computer software.

The mean age of the 66 patients was 18.7 years (range 0.5 to 72 years). The average frame time was 18.6 weeks (range 9 to 49 weeks). There was shortening present in 31 limbs with a mean of 18.6 mm (range 5 to 50 mm). Deformity correction with distraction osteogenesis was begun 7 days after the osteotomy. The mean length of time until correction was 6.7 weeks (range 3 to 13 weeks). There were a total of 10 complications (13.3%) in the series.

27 tibiae in 23 patients underwent correction with the TSF for Blount’s disease. There were 11 infantile and 16 adolescent forms. Correction of congenital deformity was performed in 20 tibiae and 8 femurs in 18 patients. There were 9 males and 9 females. There were 13 male and 8 female patients with traumatic lower limb injuries. There were 11 malunions and 10 nonunions (including 2 infected nonunions) that were corrected with the TSF.

The TaylorTM Spatial Frame is an effective technique in treating deformity. Angulation, translation, shortening and rotation can be corrected simultaneously.

Based on our results, we conclude that the TSF allows safe, gradual correction that is accurate and well tolerated.

To determine the effectiveness of six-axis analysis deformity correction using the Taylor Spatial Frame for the treatment of post-traumatic tibial malunions and non-unions, the study design was a retrospectively reviewed, consecutive series. Mean duration of follow-up: 3.2 years (range 2–4.2 years). All patients had been referred to a tertiary referral centre for deformity correction. Eighteen patients were included in the study (11 mal-unions and 7 nonunions). All deformities were post-traumatic in nature. The mean number of operations prior to the application of the spatial frame was 2.6 (range 1–6 operations). All patients completed the study. Six-axis analysis deformity correction using the Taylor Spatial Frame (Smith & Nephew, Memphis, TN) was used for correction of post-traumatic tibial malunion or nonunion. Nine patients had bone grafting at the time of frame application. One patient with a tibial plafond fracture simultaneously had deformity correction and an ankle fusion for a mobile atrophic nonunion. Two patients had infected tibial nonunions that were treated with multiple debridements, antibiotic beads, and bone grafting at the time of spatial frame application. A rotational gastrocnemius flap was used to cover a proximal third tibial defect in one patient. The average length of time the spatial frame was worn, time to healing, was 18.5 weeks (range 12–32 weeks). The main outcome measurements involved assessment of deformity correction in six axes, knee and ankle range of motion, incidence of infection, and return to preinjury activities.

Results: Seventeen of the 18 patients treated with the Taylor Spatial Frame, with adjunctive bone graft as necessary, achieved union and significant correction of their deformities in six axes, i.e. coronal angulation and translation, sagittal angulation and translation, rotation, and shortening. Fifteen of the 18 patients returned to their pre-injury activities at last follow-up.

Conclusion: Six-axis analysis deformity correction using the Taylor Spatial Frame is an effective technique in treating post-traumatic malunions and nonunions of the tibia, with several advantages over previously used devices.

Purpose: The aim of this part retrospective and part prospective study was to establish the incidence of pinsite infections and assess evolution of changes in practice

Methods: Data was collected retrospectively and prospectively for pin site infections from the inception of limb reconstruction service viz. 1985 to January 2002. There were 812 patients, 1042 limb segments, and 9935 pins. The various external fixators used were limb reconstruction system (LRS) 549; Ilizarov 397; Sheffield ring fixator (SRF); Dynamic axial fixator (DAF) 35; LRS/Sequoia 8; LRS/Garche 7; and Pennig 5.

Results: The pin site infections were graded from 0 to 6 ( Saleh & Scott). There were no infections in 206 segments. The infection grade is shown below:

We changed our pin tract care practice from 1996. We had a significant decrease in pin tract infections since then (p< 0.0001). We also found that using Ilizarov wires had significantly less infections than with half pins used with monolateral fixators (p< 0.0001; linear trend, p= 0.0338). There were 48 patients that required hospital admissions for IV antibiotics. and of these 10 patients required debridement. There were no residual long lasting infections or chronic osteomyelitis.

Conclusion: Attention to detail in insertion of wires and half pins is crucial to avoid pin site infections. This audit supports the fact that external fixation is a safe method from the point of view of infection contrary to general belief.

Aim: The aim of the study was to evaluate the outcome of open surgery for DDH in a tertiary centre.

Method: Primary and tertiary referrals between 1983 and 1996 were followed up for 8.2 years (4.1 to 16.8 years). 60 hips in 47 patients had open reduction for DDH. 39 patients were females. 13 hips had bilateral involvement. Age at operation was 2.1 years (0.1 to 5.5 years). 32 patients were referred from elsewhere for surgery after closed or open primary treatment.

Results: Clinical and radiological assessment was done on all the patients. The outcome was evaluated using the McKay system and Severin grade for subluxation. 12 hips had Type II, III or IV or unclassifiable AVN according to the Kalamchi and MacEwen classification (20%). The other results are tabulated as follows:

Complications other than AVN were re-subluxation (3), redislocation(4), fractures (1), ankylosis, LLD(4), infection (2). There was only 1 (5.9%) complication in primary referral group and 13 (30.2%) in tertiary referral group (p=0.050). Tonnis grade of subluxation, presence of ossific nucleus, tear drop shape, Mose’s grading, CE angle of Wiberg were documented but were not found to significantly affect the outcome.

Conclusion: Multiple operation increases the risk of proximal femoral growth disturbance and affects the outcome. No statistical difference was noted in the AVN rate between the primary referral group and the tertiary referral group. However, there were significantly more complications in the tertiary referral group and there maybe a need for early tertiary referral.

This paper evaluates the ability to predict the need for a tenotomy prior to beginning the Ponseti method.

The purpose of this study was to determine how one might predict the need for tenotomy at the initiation of the Ponseti treatment for clubfeet. Fifty clubfeet in thirty-five patients were treated with serial casting. The feet were prospectively rated according to two different scoring systems (Pirani, et. al. and Dimeglio, et. al.). The decision to perform a tenotomy was made when the foot could not be easily dorsiflexed 15 degrees prior to application of the final cast. Tenotomies were performed in 36 of 50 feet (72%). Those that underwent tenotomy required a significantly greater number of casts (p< 0.05). Of 27 feet with an initial Pirani score 5.0, 85.2% required a tenotomy and 14.8% did not. 94.7% of the Dimeglio Type III feet required tenotomies. At the time of the initial evaluation there was a significant difference between those that did and did not require a tenotomy for multiple components of the Pirani hind-foot score. Following removal of the last cast there was no significant difference between those that did and did not have a tenotomy.

In conclusion, children with clubfeet who have an initial score of 5.0 by the Pirani system or are rated as Type III feet by the Dimeglio system are very likely to need a tenotomy. Those that needed a tenotomy were more severely deformed with regard to all components of the hindfoot deformity, not just equinus. At the end of treatment feet were equally well corrected whether or not they needed a tenotomy.

A retrospective review of records, radiographs, Computerized Tomography (CT) scans, and Magnetic Resonance Imaging (MRI) scans was done from January 1994 to January 2002. Of the 35 patients in this study, 15 were females and 20 males. The mean age of the patients was 12.8 years (range, 9 to 19 years). There were 14 feet with bilateral coalition, 8 were right and 13 were left. There were 28 talo-calcaneal (all middle facets) coalitions of which 9 were bilateral. There were 20 calcaneo-navicular coalitions of which 5 were bilateral. One patient had a naviculo-cuboid coalition. The mean followup was 6.4 months (range, 1.2 to 36 months). Twenty six patients were treated conservatively with satisfactory outcome. Of the 23 patients operated 16 patients had good outcome, 5 had fair outcome, and 2 had poor outcome. Totally there were 10 out of 329 patients that had multiple tarsal coalition when we reviewed our cases and the literature. This gave an incidence of 3 percent of all the symptomatic tarsal coalition i.e. in other words the true incidence of multiple coalition is around 0.03%. This is the only study that establishes the incidence of multiple coalition.

To evaluate the effectiveness of a casting method for the early treatment of clubfoot deformity, a scoring system utilizing the French [DiMeglio], English [Pirani], and our functional rating system before and after each casting session was used to determine the final assessment and results of the Iowa [Ponseti] clubfoot technique.

Between Jan 2000 to June 2001, 49 clubfeet in 33 patients were assessed before and after the Ponseti casting at a minimum of 1 year follow up using the Dimeglio/ Bensahel, Hospital for Joint Diseases functional rating, and Catterall/Pirani scoring system. Mean age of presentation was 7 weeks [range 0.5 to 28 weeks]. Patients had casting +/− percutaneous TAL. At latest follow up patients who were compliant for Foot Abduction Orthosis [n=32 feet] had good results without any deterioration in their scores. Of the noncompliant patients 8 patients remained good. Of the nine feet that had poor results, 5 improved with recasting, 2 required percutaneous TAL and 2 required open TAL and posterior release.

Early treatment of the idiopathic clubfoot with serial [Ponseti] casting will be effective in over 90% of cases and patients will require no other treatment except for percutaneous tenotomy of the Achilles tendon.

Early use of the Iowa [Ponseti] technique [before the age of one year] will significantly reduce the current number of extensive surgical procedures performed for the treatment of clubfoot. Moreover, it will produce more flexible and supple feet and avoid the problem of stiff, recurrent post-surgical clubfoot.

To assess the efficacy of software assisted correction using six axes analyses for Blounts deformity.

Between 1998 and 2000, 22 tibiae in 19 patients underwent correction of Tibia Vara with the TSF. There were six females and thirteen males. There were 8 infantile and 14 adolescent forms. The mean patient age was 9.9 years (3–16 years). Shortening was present in 18 patients, averaging 11 mm (range: 3–30 mm). The mean follow up was 2.8 years (range: 2–4.1 years).

The mean preoperative varus deformity was 16.5 degrees (range, 8 to 50 degrees) which improved to 0 degree (−2 to 2 degrees), and mean procurvatum deformity was 12.2 degrees (2 to 21 degrees) which improved to 0.1 degree (−2 to 3 degrees). The plane of the deformity was an average of 31 degrees (0 to 62 degrees) from the coronal plane and the mean magnitude of the deformity was 20.5 degrees (11.3 to 3.8 degrees)

Taylor spatial frame uses the six axes software assisted analysis to correct complex deformities such as Blounts disease. It is very effective in correcting the Blounts deformity and has minimal complications.

To compare the effectiveness of ALIF, using the Hartshill Horseshoe cage, and Graf ligamentoplasty for stabilisation of comparable severity of degenerative disc disease.

Between 1995 and 1997, 27 patients who had single level ALIF with Hartshill Horseshoe cage [group A], and 28 patients who had single level Graf ligamentoplasty [group B] were assessed by Oswestry disability index, a subjective score, Zung Depression Scale [ZDS], and Modified Somatic Perception Questionnaire [MSPQ]. The two groups were similar in age and sex distribution. The patients were randomized, and procedures were all undertaken primarily for symptoms of back pain, although some patients in each group reported some leg pain. No patients with the ALIF group had any MRI evidence of neurological compromise. Where there was any degeneration at more than 1 level, discography was undertaken (8 patients in each group) confirming an isolated pain source at a single level. The duration of back symptoms and leg symptoms in the two groups was similar. There was some difference in the distribution of the MRI grade of disc degeneration between the 2 groups, but this did not reach statistical significance. Following is the characteristic of the 2 groups:

In this group, Graf ligamentoplasty procedure had a statistically significant better outcome than ALIF with the Hartshill horseshoe cage.

This may be due to the retention of some degree of normal mobility of the affected segments after stabilisation with Graf ligaments. However, at a minimum follow-up of 2 years, these represent only medium term results. There is a potential for a change in the outcome in the long term.
