Eight-plates are used to correct varus-valgus deformity (VVD) or limb-length discrepancy (LLD) in children and adolescents. It was reported that these implants might create a bony deformity within the knee joint by change of the roof angle (RA) after epiphysiodesis of the proximal tibia following a radiological assessment limited to anteroposterior (AP) radiographs. The aim of this study was to analyze the RA, complemented with lateral knee radiographs, with focus on the tibial slope (TS) and the degree of deformity correction. A retrospective, single-centre study was conducted. The treatment group (n = 64 knees in 44 patients) was subclassified according to the implant location in two groups: 1) medial hemiepiphysiodesis; and 2) lateral hemiepiphysiodesis. A third control group consisted of 25 untreated knees. The limb axes and RA were measured on long standing AP leg radiographs. Lateral radiographs of 40 knees were available for TS analysis. The mean age of the patients was 10.6 years (4 to 15) in the treatment group and 8.4 years (4 to 14) in the control group. Implants were removed after a mean 1.2 years (0.5 to 3).Aims

Angular proximal femoral deformities increase the technical complexity of primary total hip arthroplasties (THAs). The goals were to determine the long-term implant survivorship, risk factors, complications, and clinical outcomes of contemporary primary THAs in this difficult cohort. Our institutional total joint registry was used to identify 119 primary THAs performed in 109 patients with an angular proximal femoral deformity between 1997 and 2017. The deformity was related to previous femoral osteotomy in 85%, and developmental or metabolic disorders in 15%. 53% had a predominantly varus

Aims. Osteofibrous dysplasia (OFD) is a rare benign lesion predominantly affecting the tibia in children. Its potential link to adamantinoma has influenced management. This international case series reviews the presentation of OFD and management approaches to improve our understanding of OFD. Methods. A retrospective review at three paediatric tertiary centres identified 101 cases of tibial OFD in 99 patients. The clinical records, radiological images, and histology were analyzed. Results. Mean age at presentation was 13.5 years (SD 12.4), and mean follow-up was 5.65 years (SD 5.51). At latest review, 62 lesions (61.4%) were in skeletally mature patients. The most common site of the tibial lesion was the anterior (76 lesions, 75.2%) cortex (63 lesions, 62.4%) of the middle third (52 lesions, 51.5%). Pain, swelling, and fracture were common presentations. Overall, 41 lesions (40.6%) presented with radiological deformity (> 10°): apex anterior in 97.6%. A total of 41 lesions (40.6%) were treated conservatively. Anterior bowing < 10° at presentation was found to be related to successful conservative management of OFD (p = 0.013, multivariable logistic regression). Intralesional excision was performed in 43 lesions (42.6%) and a wide excision of the lesion in 19 (18.8%). A high complication rate and surgical burden was found in those that underwent a wide excision regardless of technique employed. There was progression/recurrence in nine lesions (8.9%) but statistical analysis found no predictive factors. No OFD lesion transformed to adamantinoma. Conclusion. This study confirms OFD to be a benign bone condition with low rates of local progression and without malignant transformation. It is important to distinguish OFD from adamantinoma by a histological diagnosis. Focus should be on

Introduction. Coronal malalignment and leg length discrepancies (LLD) are frequently associated. Temporary hemiepiphysiodesis (tHED) is commonly employed for the correction of limb malalignment in skeletally immature patients. For treatment of LLD greater than 2 cm, lengthening with intramedullary legnthening nails is a safe and reliable technique. However, the combined application of these approaches in skeletally immature patients has not yet been investigated. Materials & Methods. Retrospective radiological and clinical analysis of 25 patients (14 females, 11 males) who underwent intramedullary femoral lengthening with an antegrade PRECICE® lengthening nail as well as tHED of the distal femur and / or proximal tibia between 2014 and 2019. tHED was conducted by implantation of flexible staples (FlexTack™) either prior (n = 11), simultaneously (n = 10), or subsequently (n = 4) to femoral lengthening. The mean follow-up period was 3.7 years (±1.4). Results. The median initial LLD was 39.0 mm (35.0–45.0). 21 patients (84%) presented valgus and 4 (16%) showed varus malalignment. Leg length equalization was achieved in 13 patients at skeletal maturity (62%). The median LLD of patients with a residual LLD > 10 mm was 15.5 mm (12.8–21.8). Limb realignment was obtained in nine of seventeen skeletally mature patients (53%) in the valgus group, and in one of four patients (25%) in the varus group. Conclusions. The combination of antegrade femoral lengthening and tHED can efficiently correct LLD and coronal limb malalignment in skeletally immature patients. Nevertheless, achieving limb length equalization and realignment may render difficult in cases of severe LLD and

Purpose.
The traditional techniques involving an oblique
tunnel or triangular wedge resection to approach a central or mixed-type
physeal bar are hindered by poor visualisation of the bar. This
may be overcome by a complete transverse osteotomy at the metaphysis
near the growth plate or a direct vertical approach to the bar.
Ilizarov external fixation using small wires allows firm fixation
of the short physis-bearing fragment, and can also correct an associated angular
deformity and permit limb lengthening. . We accurately approached and successfully excised ten central-
or mixed-type bars; six in the distal femur, two in the proximal
tibia and two in the distal tibia, without damaging the uninvolved
physis, and corrected the associated
Modern methods of deformity correction such as the Taylor Spatial Frame (TSF) allow correction of deformities to within tolerances of 1° and 0.5mm. Plain X-radiography using orthogonal views is the current standard for the assessment for the evaluation of
Introduction. The purpose of our study was to retrospectively analyze our patients who were treated for FH and PFFD by means of guided growth temporary Hemiepiphysiodesis. We sought to determine the effectiveness of the procedure, as well as its success rates, complications, and rebound phenomena. Materials and Methods. We retrospectively reviewed the medical records and all routine preoperative and post operative long standing radiograph of all the FH and PFFD patients that were operated in our institute using guided growth hemiepiphysiodesis technique of distal femur or proximal tibia between 2007 to 2017. Results. 42 patients (28/FH, 14/PFFD) with 55 involved physis were included in the study. The mean duration of follow-up was 51.11 ± 27.56 months after the first operation. The average age at first plate insertion was 11.7 years and 50% of patients reached puberty by the time of data collection. 32 physes (21 FH, 11 PFFD) were operated due to pathological mLDFA with a mean angle correction of 6.24° for the FH group and 6° for the PFFD group and time-to-correction of 14.07 months and 11.56 months, respectively. 23 physes (14 FH, 9 PFFD) were operated due to pathological mMPTA with a mean angle correction of 4.43° for the FH group and 6.22° for the PFFD group with time-to-correction of 17.95 months and 20.35 months respectively. 40% (12/30) of patients, whose metalwork was removed, had a recurrence of the deformity, 7/21 [33.3%] in the FH group and 5/9 [55%] in the PFFD group. All required a second hemiepiphysiodesis operation. 2. nd. rebound was recorded in 3/21 (14%) FH patients and 2/9 (22%) PFFD patients. Conclusions. Temporary hemiepiphysiodesis is an effective treatment of

Osteomyelitis and septic arthritis are common pathologies in young children. Because of their skeletal immaturity, children are particularly vulnerable to orthopaedic complications, including limb-length discrepancies,
Septicaemia resulting from meningococcal infection is a devastating illness affecting children. Those who survive can develop late orthopaedic sequelae from growth plate arrests, with resultant complex deformities. Our aim in this study was to review the case histories of a series of patients with late orthopaedic sequelae, all treated by the senior author (CFB). We also describe a treatment strategy to address the multiple deformities that may occur in these patients. Between 1997 and 2009, ten patients (seven girls and three boys) were treated for late orthopaedic sequelae following meningococcal septicaemia. All had involvement of the lower limbs, and one also had involvement of the upper limbs. Each patient had a median of three operations (one to nine). Methods of treatment included a combination of angular deformity correction, limb lengthening and epiphysiodesis. All patients were skeletally mature at the final follow-up. One patient with bilateral below-knee amputations had satisfactory correction of her right amputation stump deformity, and has complete ablation of both her proximal tibial growth plates. In eight patients length discrepancy in the lower limb was corrected to within 1 cm, with normalisation of the mechanical axis of the lower limb. Meningococcal septicaemia can lead to late orthopaedic sequelae due to growth plate arrests. Central growth plate arrests lead to limb-length discrepancy and the need for lengthening procedures, and peripheral growth plate arrests lead to
First generation condylar knee replacements suffered from 2 prominent observations: Difficulty in stair climbing and Limited range of motion. Improved understanding of knee kinematics, the importance of femoral rollback, and enhanced stability in flexion led to 2 differing schools of thought: posterior cruciate ligament retention or posterior cruciate substitution. The advantages of posterior cruciate substitution include predictable CAM-post engagement leading to rollback, predictable ROM, stability during stair climbing, ease of knee balancing regardless of degree of

Background. Correct positioning of the femoral component in resurfacing hip arthroplasty (RHA) is an important factor in successful long-term outcomes. The purpose of computer-assisted navigation (CAS) in resurfacing is to insert the femoral neck guide wire with greater accuracy and to help size the femoral component, thus reducing the risk of notching at the head and neck junction. Several recent studies reported satisfactory precision and accuracy of CAS. However, there is little evidence that CAS is useful in the presence of anatomical deformities of the proximal femur, which is frequently observed in young patients with secondary degenerative joint disease. Aim. The purpose of this in vitro study was to determine the accuracy of an image-free RHA navigation system in the presence of
We reviewed 13 children with partial growth plate arrest who had been treated by epiphyseolysis. Eight were followed to skeletal maturity and five for at least four years. In three cases the affected limb was restored to normal and in five the operation was successful in improving
Limb deformity is common in patients presenting for knee arthroplasty, either related to asymmetrical wear patterns from the underlying arthritic process (intra-articular malalignment) or less often major extra-articular deformity due to prior fracture malunion, childhood physical injury, old osteotomy, or developmental or metabolic disorders such as Blount's disease or hypophosphatemic rickets.
Management of open tibial fractures remains controversial. We hypothesised that unreamed intramedullary nail offers inherent advantages of nail as well as external fixation. We undertook a prospective randomised study to compare the results of management of open tibial fractures with either an external fixator or an undreamed intramedullary nail until fracture union or failure. Our study included 30 consecutive open tibial fractures (Gustilo I, II & IIIA) between 4 cm distal to knee and 4 cm proximal to ankle in skeletally mature adults, who presented to a level-1 trauma centre. Alternate patients were treated by either external fixation and unreamed nailing i.e. 15 in each group. Standard protocol for debridement and fixation was followed in all cases. All external fixators were removed at 6 weeks. All cases were followed up until fracture union, the main outcome measurement. 26 (87%) were males and 4 (13%) females; age range was 20-60 years (average 33.8). All fractures in both groups united. Time to union averaged 7.9 months for both groups. Incidence of wound problems, infection, hardware failure and delayed union were comparable. However, there was higher incidence of

a State-wide trauma registry in Australia: 195 had been treated
with a locking plate and 102 with an IMN. Baseline characteristics
of the patients and their fractures were recorded. Health-related

We performed limb lengthening and correction of deformity of nine long bones of the lower limb in six children (mean age, 14.7 years) with osteogenesis imperfecta (OI). All had femoral lengthening and three also had ipsilateral tibial lengthening.
Purpose: Femoral torsion is traditionally treated by a proximal osteotomy. At this level, a significant exposure is required. Furthermore, internal fixation is typically removed by additional surgery at twelve months. We propose to demonstrate the efficacy of the AO external fixator to maintain osteotomies in the distal femur for torsional correction. Method: Between September 1994 and April 2001, supracondylar osteotomies were performed on 38 femora in 21 children with torsional and
Gradual correction of periarticular deformities has necessitated the application of external fixators to accomplish the task. By contrast, such deformities when treated by acute correction are most often stabilised using internal fixation. Hemi-epiphyseal arrest, by stapling or transphyseal screw is a disadvantage by being an irreversible process which has to be delayed until later childhood. This study describes the preliminary results of using an alternative internal device which corrects

Meningococcal septicaemia from meningococcal infection is a devastating illness affecting children. Advances in medical management have reduced the mortality rate to approximately 15 to 20% and children who survive can develop late orthopaedic sequelae from growth plate arrests with resultant complex deformities. Our aim in this study was to review and analyze the case histories of a series of patients with late orthopaedic sequelae, all treated by the senior author. We describe a treatment strategy to address the multiple deformities that may occur in these patients. Methods & Results Between 1990 and 2009, 12 patients were treated for late orthopaedic sequelae after meningococcal septicaemia by the senior author. There were 8 girls and 4 boys. All patients had lower limb involvement. 1 patient had involvement of the upper limb requiring treatment. Each patient had had a mean of 3 operations (range from 2 to 9). Methods of treatment included a combination of angular deformity correction, limb lengthening and epiphysiodesis. At final follow-up 9 of the 12 patients were skeletally mature. In 9 patients limb length discrepancy in the lower limb was corrected to within 1 cm, with normalization of the lower limb mechanical axis. Conclusion. Meningococcal septicaemia can lead to late orthopaedic sequelae due to growth plate arrests. Central growth plate arrests leads to limb length discrepancy, and partial growth plate arrests leads to an
Introduction Hallux valgus (HV) is a common foot deformity with a prevalence of up to 48%. It usually affects females and its radiographic severity is expressed by various angles, such as the HV Angle, the Inter Metatarsal Angle (IMA) and the Distal Metatarsal Articular Angle (DMAA). The aim of our study was to assess the impact that HV has on patients’ quality of life and to correlate each of the above angles to SF-36 sub-scales. Method Twenty-three female patients with a mean age of 48.5 years were included in the study. Diagnosis was established by clinical and standardised radiological examination. Patients were medically fit and the only pathology that could affect their SF-36 score was HV. They all completed in the SF-36 form on their first visit at the clinic. Statistical analysis was performed via SPSS 12.0. Results Mean radiographic

Purpose: End results analysis of surgical treatment of posttraumatic bone defects in the lower extremity by Ilizarov method and intramedullary nailing augmentation during consolidation. Materials and method: Between 1990–2000,83 patients with posttraumatic bone defect (femur 26, tibia 57) with an average age of 38 years (11–65y.) were surgically treated. Open fracture was the cause of bone defect in 50 patients (60%). In the rest 33 (40%) patients, the bone defect was the result of a surgical removal of a nonviable bone due to osteomyelitis or infected non-union. The average length of bone defect was 8,5 cm. (4–20 cm.). In all cases corticotomy and application of Ilizarov device was necessary to initiate bone transport. In 26 patients the Ilizarov device was removed during consolidation and interlocking intramedullary nailing was performed. Selection criteria for changing method were: 1) delayed union at the docking site (13 pt.), 2) Intolerance of the Ilizarov device (6 pt.), 3)

Objective: To study deformities in tibial fractures that are treated orthopedically. Material and Methods: A prospective study of 42 tibial fractures treated orthopedically (1996–2003), Average age was 8.9 years, Nineteen (45.2%) were male and 23 (54.3%) were female. Average follow-up was 59.6 months. Nineteen of the fractures (45.2%) were medial third and 23 (54.8%) were distal. The fracture line was spiral in 26 cases (61.9%), oblique in 10 cases (23.8%) and transverse in 6 (4.8%). In 18 cases (42.9%), there was a facture of the fibula and in 24 cases there was not (57.1%). Exclusion criteria: previous fractures,
Purpose: The purpose of this study was to evaluate the results of 23 patients with septic nonunion of the distal tibial metaphysis type Pilon fractures treated with Ilizarov technique. Material and Methods: Between 1990 and 2002 the Ilizarov technique was used in 23 patients with posttraumatic infected nonunion of the distal tibia. Seventeen were males and 6 females. Average age was 40.1 years (range16–68 years). Mean duration of nonunion was 13,8 months and the average number of failed previous surgical procedures 2.2. According to AO classification there were 3 non-unions with quiescent infection and no drainage, 4 with active infection and no drainage, and 16 with infection and drainage. The ankle joint was ankylosed in 6 patients preoperatively and it was painful in all patients. Thirteen patients had an
In this paper the results of correction of bone deformities using the llizarov methods, are presented. Fifty-nine patients, 42 with malunion and 17 with mal-nonunion of tibia or femur were operated upon using the llizarov circular fixator. Another 28 cases were corrected using a unilateral device. There were: a) 30
Increased incidence of complications has been reported when lengthening limbs with underlying bone disorders such as dysplasias and metabolic bone diseases. There is a paucity of literature on limb lengthening in Osteogenesis Imperfecta (OI), probably due to the concern that the bone containing abnormal collagen may not tolerate the external fixators for a long term and there may not be adequate regenerate formation from this abnormal bone. We performed limb lengthening and deformity correction of nine lower limb long bones in six children with OI. Four children were type I and two were type IV OI as per Sillence classification. The mean age was 14.7 years. All six children had lengthening for femoral shortening and three of them also had lengthening for tibial shortening on the same side.
The aim of this study is to evaluate the efficiency of the Sheffield Ring Fixator (SRF) in the management of tibial deformity. Tibial deformity correction is challenging and requires an efficient system with strong bony fixation.Progressive correction is usually necessary due to the low compliance of the anatomical compartments. The SRF provides an effective solution, employing a combination of wire and screw fixation for metaphyseal corrections and all screw fixation for diaphyseal corrections. We reviewed a consecutive series of 50 patients with tibial deformity treated by progressive correction using the SRF between 1997 and 2000. The mean age was 33 years (range 18 to 65). Thirty nine cases were due to post-traumatic deformity and eleven as sequelae of childhood disease. Cases were analysed to ascertain the degree of deformity, treatment time, final outcome in terms of the accuracy of correction of deformity, and incidence of complications. All patients had significant

Aim. Simultaneous use of Ilizarov techniques with transfer of free muscle flaps is not current standard practice. This may be due to concerns about duration of surgery, clearance of infection, potential flap failure or coordination of surgical teams. We investigated this combined technique in a consecutive series of complex tibial infections. Method. A single centre, consecutive series of 45 patients (mean age 48 years; range 19–85) were treated with a single stage operation to apply an Ilizarov frame for bone reconstruction and a free muscle flap for soft-tissue cover. All patients had a segmental bone defect in the tibia, after excision of infected bone and soft-tissue defects which could not be closed directly or with local flaps. We recorded comorbidities, Cierny-Mader and Weber-Cech classification, the Ilizarov method used, flap type, follow-up duration, time to union and complications. Results. 26 patients had osteomyelitis and 19 had infected non-union. Staphylococci were cultured in 25 cases and 17 had polymicrobial infections. Ilizarov monofocal compression was used in 14, monofocal distraction in 15, bifocal compression/distraction in 8, and bone transport in 8. 8/45 had an additional ankle fusion, 7/45 had an

Introduction: The consequences of incorrect implant orientation and improper limb alignment in TKR surgery are: 1) accelerated implant wear; 2) early prosthesis loosening; 3) sub optimal clinical function. Although mechanical alignment guides have improved the precision of TKR surgery, it has been estimated that alignment errors of more than 3 degrees occur in at least 10% of TKR even when performed by experienced surgeons using mechanical alignment systems of modern design. The purpose of this study was to determine the accuracy of TKR surgery performed with conventional instruments using a computer assisted navigation system (OrthoPilot) as a measurement tool. Methods: 35 patients underwent primary TKR performed with a conventional intramedullary, mechanical instrumentation system. Minimal follow-up was 1 year. The OrthoPilot was used to measure: 1) pre-operative limb alignment; 2) pre-operative medial-lateral stability; 3) pre-operative flexion; 4) post-operative alignment; 5) post-operative medial-lateral stability; 6) post-operative flexion. Patients consented to the use of the Ortho-Pilot as part of an Investigation Review Board approved study. Limb and implant alignment were measured on pre- and post-operative x-rays and compared to the alignment results measured by OrthoPilot. Knee society scores were obtained on all patients. Results: No complications were associated with the use of the OrthoPilot. Post-operative pain and function were not affected by the use of the OrthoPilot. Pre-operative
Aim. Simultaneous application of Ilizarov frames and free muscle flaps to treat osteomyelitis or infected non-unions is currently not standard practice in the UK, in part related to logistical issues, surgical duration and challenging access for microvascular anastomosis. We present the outcomes for 56 such patients. Methods. Retrospective single centre consecutive series between 2005–2017. We recorded comorbidities, Cierny-Mader and Weber-Cech classification, the Ilizarov method used, flap and anastomosis used, follow-up duration, time to union and complications. Results. 56 patients (55 tibiae and 1 forearm) were included (mean age 48 years). Thirty-four cases had osteomyelitis (20/34 Cierny-Mader Stage IV) and 22 had an infected non-union (14/22 Weber-Cech Type E or F). Forty-six patients had a segmental defect after resection. Monofocal compression was used in 14, monofocal distraction in 15, bifocal compression/distraction in 8, bone transport in 9 and a protective frame in 10. 8/56 had an ankle fusion, 7/56 had an
The epiphyseal approach to a chondroblastoma of the intercondylar notch of a child’s distal femur does not provide adequate exposure, thereby necessitating the removal of a substantial amount of unaffected bone to expose the lesion. In this study, we compared the functional outcomes, local recurrence, and surgical complications of treating a chondroblastoma of the distal femoral epiphysis by either an intercondylar or an epiphyseal approach. A total of 30 children with a chondroblastoma of the distal femur who had been treated by intraregional curettage and bone grafting were retrospectively reviewed. An intercondylar approach was used in 16 patients (group A) and an epiphyseal approach in 14 (group B). Limb function was assessed using the Musculoskeletal Tumor Society (MSTS) scoring system and Sailhan’s functional criteria.Aims

The use of retrograde femoral intramedullary nails in children for deformity correction is controversial. It is unknown if the injury to the central part of the growth plate results in premature bony union, leading to limb deformities or discrepancies. The aim of this study was to assess physeal healing and bone growth after insertion of a retrograde femoral nail thorough the centre of the physis in a skeletally immature experimental porcine model. Eleven immature pigs were included in the study. One leg was randomised for operation with a retrograde femoral nail (diameter 10.7 mm), whilst the non-operated contralateral remained as control. All nails were inserted centrally in coronal and sagittal plane under fluoroscopic guidance, and the nails spanned the physis. The nails were removed at 8 weeks. Both femora in all animals underwent MRI at baseline (pre-operatively), 8 weeks (after nail removal) and 16 weeks (before euthanasia). Femoral bone length was measured at 5 sites (anterior, posterior, central, lateral and medial) using 3d T1-weighted MRI. Growth was calculated after 8 weeks (growth with nail) and 16 weeks (growth without nail). Physeal cross-sectional area and percentage violated by the nail was determined on MRI. Operated side was compared to non-operated. Corresponding 95% confidence intervals were calculated. No differences in axial growth were observed between operated and non-operated sides. Mean growth difference was 0,61 mm [−0,78;2,01] whilst the nail was inserted into the bone and 0,72 mm [−1,04;1,65] after nail removal. No signs of

Originally used for correction of angular malalignment, 2 hole plate epiphyseodesis has recently gained popularity in paediatric orthopaedic practice for the correction of leg length discrepancy. In this study we aim to assess the efficiency of guided growth plates in correcting leg length discrepancy. Thirty-three children treated for leg length discrepancy with guided growth plates (“8-Plate”, Orthofix, Inc and “I-Plate”, Orthopediatrics) in a tertiary referral centre were retrospectively analysed. Medial and Lateral plates were inserted for symmetrical growth reduction and patients were followed up with clinical and radiological assessment. Thirty patients had distal femoral epiphyseodesis and three had proximal tibial epiphyseodesis. Leg lengths and individual bone lengths were measured from pre and post – operative radiographs. The angle between the screws was measured from radiographs taken intra operatively and at the time of final follow up to assess screw divergence with growth. Efficiency was calculated as the ratio of growth inhibition achieved to the projected discrepancy at maturity if left untreated. At a mean follow up of 17 months (4–30 m) leg length discrepancy improved from a mean of 30 mm (50–15mm) to 13 mm (2.5–39mm) (p < 0.01). The angle between screws increased from 6 degrees to 26 degrees over the follow up period. Efficiency was found to be 66%. There were 5 patients with
Aims. This study reviews the use of a titanium mesh cage (TMC) as an
adjunct to intramedullary nail or plate reconstruction of an extra-articular
segmental long bone defect. Patients and Methods. A total of 17 patients (aged 17 to 61 years) treated for a segmental
long bone defect by nail or plate fixation and an adjunctive TMC
were included. The bone defects treated were in the tibia (nine),
femur (six), radius (one), and humerus (one). The mean length of
the segmental bone defect was 8.4 cm (2.2 to 13); the mean length
of the titanium mesh cage was 8.3 cm (2.6 to 13). The clinical and
radiological records of the patients were analyzed retrospectively. Results. The mean time to follow-up was 55 months (12 to 126). Overall,
16 (94%) of the patients achieved radiological filling of their
bony defect and united to the native bone ends proximally and distally,
resulting in a functioning limb. Complications included device failure
in two patients (12%), infection in two (12%), and wound dehiscence
in one (6%). Four patients (24%) required secondary surgery, four
(24%) had a residual limb-length discrepancy, and one (6%) had a

The aim of this study was to assess the safety and clinical outcome of patients with a femoral shaft fracture and a previous complex post-traumatic femoral malunion who were treated with a clamshell osteotomy and fixation with an intramedullary nail (IMN). The study involved a retrospective analysis of 23 patients. All had a previous, operatively managed, femoral shaft fracture with malunion due to hardware failure. They were treated with a clamshell osteotomy between May 2015 and March 2020. The mean age was 42.6 years (26 to 62) and 15 (65.2%) were male. The mean follow-up was 2.3 years (1 to 5). Details from their medical records were analyzed. Clinical outcomes were assessed using the quality of correction of the deformity, functional recovery, the healing time of the fracture, and complications.Aims

As an alternative to external fixators, intramedullary lengthening nails (ILNs) can be employed for distraction osteogenesis. While previous studies have demonstrated that typical complications of external devices, such as soft-tissue tethering, and pin site infection can be avoided with ILNs, there is a lack of studies that exclusively investigated tibial distraction osteogenesis with motorized ILNs inserted via an antegrade approach. A total of 58 patients (median age 17 years (interquartile range (IQR) 15 to 21)) treated by unilateral tibial distraction osteogenesis for a median leg length discrepancy of 41 mm (IQR 34 to 53), and nine patients with disproportionate short stature treated by bilateral simultaneous tibial distraction osteogenesis, with magnetically controlled motorized ILNs inserted via an antegrade approach, were retrospectively analyzed. The median follow-up was 37 months (IQR 30 to 51). Outcome measurements were accuracy, precision, reliability, bone healing, complications, and patient-reported outcome assessed by the Limb Deformity-Scoliosis Research Society Score (LD-SRS-30).Aims

Aim. To investigate the effect of the eight plate position in sagittal plane on tibial slope in temporary epiphysiodesis technique applied to the proximal tibia and whether there is a rebound effect after removing the plate. Method. Forty New Zealand rabbits (6 weeks old) were divided into four groups. In all groups, two 1.3 mm mini plates and cortical screws implantation were placed on both medial and lateral side of the proximal epiphysis of the right tibia. In Group 1 and 3, the plates were placed on anterior of the proximal tibial anatomical axis in the sagittal plane, and placed posteriorly in Group 2 and 4. The left tibia was examined as control in all groups. Group 1 and Group 2 were sacrificed after four week-follow-up. In Group 3 and Group 4, the implants were removed four weeks after index surgery and the rabbits were followed four more weeks to investigate the rebound effect. The tibial slope was measured on lateral X-rays every two weeks. Both medial and lateral plateau slopes were evaluated on photos of the dissected tibia. Results. In Group 1, right MTPA (medial tibial plateau angle) and left MTPA, right LTPA (lateral tibial plateau angle) and left LTPA, and right 4wTPPA (the tibial proximal posterior angle at 4th week) and left 4wTPPA values were compared with each other. There was a significant difference in MTPA, LTPA, and 4wTPPA in Group 1 (p: 0.003, 0.006, 0.004). In Group 1, the medial and lateral slope significantly decreased after 4 weeks. There was no significant difference in MTPA, LTP and 4wTPPA measurements in Group 2 (p= 0.719, 0.306, 0.446, respectively). In Group 2, the slope did not change in four weeks. There was a significant difference in MTPA, LTPA, 4wTPPA, and 8wTPPA (tibial proximal posterior angle at 8th week) in Group 3 (p= 0.005, 0.002, <0.001, <0.001, respectively). In Group 3, the slope decreased at 4th week and remained stabile during the next four week-follow up and no rebound effect was observed. There was no significant difference in MTPA, LTPA, 4wTPPA, and 8wTPPA measurements in Group 4 (p= 0.791, 0.116, 0.232, 0.924), respectively. In group 4, slope did not change at 4th week of index surgery and no rebound effect was observed in the next four week-follow up. Conclusion. If eight plates were placed on anterior of lateral proximal tibia axis on both medial and lateral side, the tibial slope would reduce, and remain stabile after implant removal. Care should be taken to place the plates on the line of proximal tibial axis in sagittal plane in temporary epiphysiodesis technique performed due to
Purpose. The purpose of this study was to assess the accuracy of three-dimensional camera technology when monitoring deformity correction by an Ilizarov frame and to compare it to manual measurements. Methods and Results. A model consisting of an Ilizarov frame built around an artificial tibia and fibula was used with retro-reflective markers placed on the frame and bones to allow for the positions of each to be detected by the camera system. Measurements made by the camera system were compared to measurements taken manually. In the assessment of frame lengthening, the camera system average error was 2% (SD 2%) compared to 7% (SD 6%) for manual measurement. In the assessment of bone lengthening, the camera system average error was 4% (SD 4%) compared to 34% (SD 8%) for manual measurement. The technology also demonstrated good accuracy in the measurement of

Introduction. We investigated the usefulness of flap surgery for Gustilo type IIIB and C severe open fracture of the tibia, for which treatment is difficult. Materials & Methods. The subjects were 16 patients with severe open fracture of the tibia who received a treatment at our division between April 2000 and October 2008. There were 13 males and 3 females, and the mean age at injury was 41.2 years. Radical debridement and temporal external fixation were performed on the day of injury, and soft tissue reconstruction and definitive osteosynthesis were performed within a few days after injury to the best. Results. The affected limb was salvaged in all patients. Primary bone healing was obtained in 13 of the 16 patients, and the mean bone healing time was 5.5 months (3–7 months). The patient with delayed bone healing underwent additional bone grafting and achieved bone healing. Concomitant osteomyelitis occurred in 4 of 16 patinets (25%). Leg shortening was observed in 1 patient, but the shortening was only 2 cm. No patient exhibited 10 or more degrees of
Background. Although gradual bone transport may provide a large-diameter bone, complications are common with the long duration of external fixation. To reduce such complications, a new technique of bone transport with a locking plate has been done for tibial bone defect. Methods. In 13 patients (mean age, 38.9 years) of chronic osteomyelitis or traumatic bone defect, segmental transport was done using external fixator with a locking plate. In surgical technique, a locking plate was fixed submuscularly, holding the proximal and distal segments. Then, the external fixator for transport was fixed without contact of the locking plate. After docking, 2 or 3 screws were fixed at the transported segment through the plate holes. At the same time, the external fixator was removed. Results. The mean transported amount was 5.8cm, and the mean external fixation index was 13.3 days/cm. The primary union at the docking site was achieved in all cases. No patients showed
Postoperative malalignment of the femur is one of the main complications in distal femur fractures. Few papers have investigated the impact of intraoperative malalignment on postoperative function and bone healing outcomes. The aim of this study was to investigate how intraoperative fracture malalignment affects postoperative bone healing and functional outcomes. In total, 140 patients were retrospectively identified from data obtained from a database of hospitals participating in a trauma research group. We divided them into two groups according to coronal plane malalignment of more than 5°: 108 had satisfactory fracture alignment (< 5°, group S), and 32 had unsatisfactory alignment (> 5°, group U). Patient characteristics and injury-related factors were recorded. We compared the rates of nonunion, implant failure, and reoperation as healing outcomes and Knee Society Score (KSS) at three, six, and 12 months as functional outcomes. We also performed a sub-analysis to assess the effect of fracture malalignment by plates and nails on postoperative outcomes.Aims

Knowledge on total knee arthroplasties (TKAs) in patients with a history of poliomyelitis is limited. This study compared implant survivorship and clinical outcomes among affected and unaffected limbs in patients with sequelae of poliomyelitis undergoing TKAs. A retrospective review of our total joint registry identified 94 patients with post-polio syndrome undergoing 116 primary TKAs between January 2000 and December 2019. The mean age was 70 years (33 to 86) with 56% males (n = 65) and a mean BMI of 31 kg/m2 (18 to 49). Rotating hinge TKAs were used in 14 of 63 affected limbs (22%), but not in any of the 53 unaffected limbs. Kaplan-Meier survivorship analyses were completed. The mean follow-up was eight years (2 to 19).Aims

Distraction osteogenesis with intramedullary lengthening devices has undergone rapid development in the past decade with implant enhancement. In this first single-centre matched-pair analysis we focus on the comparison of treatment with the PRECICE and STRYDE intramedullary lengthening devices and aim to clarify any clinical and radiological differences. A single-centre 2:1 matched-pair retrospective analysis of 42 patients treated with the STRYDE and 82 patients treated with the PRECICE nail between May 2013 and November 2020 was conducted. Clinical and lengthening parameters were compared while focusing radiological assessment on osseous alterations related to the nail’s telescopic junction and locking bolts at four different stages.Aims

Background. Tension band epiphysiodesis for lower limb length discrepancy in children Planned physeal growth arrest (epiphysiodesis) for the treatment of limb length discrepancy (LLD) in growing children is a well described treatment modality in the literature. We describe our experience of temporary epiphysiodesis using a tension band technique with the “8-plate” in the treatment of LLD in growing children. Aim. The main objective of this study was to confirm whether bilateral 8-plates achieve an epiphysiodesis or not?. Methods and results. This is a prospective study of 27 patients who were treated with 8-plate epiphysiodesis for limb length discrepancy with a mean follow up of 28 months. Perthes disease was the most common underlying pathology for the LLD. The average preoperative LLD was 25.9 mm (15–49 mm). 17 patients successfully corrected to < 15 mm LLD, 5 patients corrected to between 15–20 mm and 5 patients did not correct to with in 15 mm LLD (22.2%). In those patients whom have corrected, the average correction length was 25.6 months with an average correction rate of 1.52 mm per month. There was a trend for insufficient equalisation if the procedure was performed < 1.5 years prior to skeletal maturity. The was also a trend for insufficient equalisation if performed at single physis only (femur or tibia). Complications included one superficial infection and one deep infection following plate removal at the end of treatment. Screw breakage was noticed in one patient. No long term complications were reported. No
The purpose of this study was to determine the oblique plane deformity in slipped upper femoral epiphysis.

Patients in whom a CT scan had been performed in addition to plain radiographs were assessed further.
We re-examined clinically and radiologically 88 patients with a fracture of the lower leg at a mean follow-up of 15 years. Forty-three fractures (49%) had healed with malalignment of at least 5°. More arthritis was found in the knee and ankle adjacent to the fracture than in the comparable joints of the uninjured leg. Malaligned fractures showed significantly more degenerative changes. Eighteen patients (20%) had symptoms in the fractured leg. There was a significant correlation between symptoms in the knee and arthritis but not between symptoms and ankle arthritis or malalignment. We conclude that fractures of the lower leg should be managed so that the possibility of
To consider bilateral simultaneous knee replacement, both knees must have significant structural damage. It is best if the patient can't decide which knee is more bothersome. In borderline cases, ask the patient to pretend that the worse knee is normal and if so, would they be seeing you for consideration of knee replacement on the less involved side. If the answer to this question is “yes,” consider the patient a potential candidate for bilateral knee replacement. If the answer is “no,” recommend operating only on the worse knee, and expect that the operation on the second knee can probably be delayed for a considerable period of time. Strong indications for bilateral simultaneous TKA are bilateral severe
