Abstract Background Difficulty in obtaining union, recurrent fractures, and residual deformities remain the problems challenging the management of congenital pseudarthrosis of the tibia (CPT). We applied the “Eiffel Tower” double titanium elastic nails (TENs) in the existing combined approach, which takes advantages of TEN’s mechanical stability with the protection against refracture, Ilizarov’s high fusion rate with alignment control and the biologic environment provided by bone grafting for bony union. The results of this procedure are presented and discussed. Methods Seventeen patients with CPT treated by combined surgery including pseudarthrosis resection, the “Eiffel Tower” double TENs technique, autogenous iliac bone grafting, and Ilizarov fixation between 2013 and 2019 were retrospectively investigated. Signs of bone union, limb length discrepancy (LLD), rate of refracture, and degree of residual deformities were reviewed. The AOFAS Ankle Hindfoot scale and measurement of ankle motion were used to evaluate ankle function. The mean follow-up time was 40.5 (11 to 91) months. Results The mean age at index surgery was 6.2 (2.5 to 15) years. Union of the pseudarthrosis was achieved in 100% of cases. Among them, 15 (88.2%) patients obtained union of the pseudarthrosis on the first attempt (primary union). The average time to primary union was 3.8 (2 to 6) months. The rest 2 cases achieved union after additional surgeries (secondary union). In terms of complications, refracture occurred in 2 patients (11.8%) and 4 patients (23.5%) developed pin infection. The mean limb length discrepancy at the final follow up was 33.4 (6–141) mm. The average AOFAS score improved from 38.2 (27 to 51) pre-operatively to 77 (63 to 87) post-operatively (p < 0.01). Conclusions The “Eiffel Tower” double TENs technique is an ideal intramedullary fixation method in the surgical treatment of CPT. The combination of TENs technique with bone grafting and Ilizarov fixation has the advantages of early bone union, less injury on metaphysis, and early functional recovery. Level of evidence Level IV.

Abstract Background: To report the preliminary outcome of treating congenital pseudarthrosis of the tibia (CPT) by using titanium elastic nails (TENs) combined with other surgical procedures including pseudarthrosis resection, autogenous iliac bone grafting and Ilizarov technique, with a mean follow-up time of 4.5 (3.3 to 6.3) years.Methods: 15 patients with CPT treated by combined surgery including pseudarthrosis resection, titanium elastic nails (TENs) technique, autogenous iliac bone grafting and Ilizarov fixation between 2013 and 2017 were retrospectively investigated. Signs of bone union, limb length discrepancy (LLD), rate of refracture and degree of residual deformities were reviewed. The AOFAS Ankle Hindfoot scale and measurement of ankle movement were used to evaluate ankle function. Results: The mean age at index surgery was 110 (24 to 285) months. 13 (86.7 %) patients obtained union of the pseudarthrosis on the first attempt (primary union). The average time to primary union was 4.8 (3 to 7) months. The rest 2 cases achieved union after additional surgeries (secondary union). In terms of complications, refracture occurred in 2 patients (13.3%) and 5 (33.3%) patients developed pin infection. The mean limb length discrepancy at the final follow up was 14.6 (4–41) mm. 3 patients (20 %) had ankle valgus deformities with a mean LDTA of 74.3° (range, 68 to 81°). The average AOFAS score improved from 40.3 (27 to 51) pre-operatively to 76.1 (63 to 87) post-operatively. For the patients who received proximal tibial lengthening, the average healing index (HI) was 65.1 (57.3 to 77.8) days/cm.Conclusions: Titanium elastic nails (TENs) technique is an ideal intramedullary fixation method in the surgical treatment of CPT. The combination of TENs technique with bone grafting and Ilizarov fixation has the advantages of early bone union, less injury on metaphyseal and early functional recovery.

Introduction: The aim of this retrospective case-control study is to evaluate clinical and radiographic results of short stems compared with traditional hip prostheses. Methods: 46 short stems (SS) and 50 traditional stems (TS) were selected. All the stems were implanted by the same surgeon using posterior approach because of primary osteoarthritis, post-traumatic osteoarthritis and avascular necrosis. All the patients were compared clinically by Harris Hip Score (HHS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analogue scale (VAS), 12-item Short Form Health Survey (SF-12F/M) and radiographically (offset, CD angle, limb length discrepancy, cup inclination, subsidence, osseointegration, heterotopic ossification). Radiographic evaluations were carried out by 3 different blinded surgeons. A statistical analysis was performed (chi-square, t-test, Mann-Whitney). Results: At a mean follow-up of 30 months all the implanted stems were well-positioned and osseointegrated. In both groups there was a marked improvement in pain ( p < 0.001) with a statistically significant advantage in the SS group for WOMAC (90.8 vs. 87.5; p = 0.02) and in part for HHS (93 vs. 91.7; p = 0.18). The radiographic evaluations, with high concordance correlation between the 3 blinded surgeons (ICC consistently >0.80), showed no significant differences in the restoration of the articular geometry, with a reduction of cortical hypertrophy (2% SS vs. 7% TS) and periprosthetic stress-shielding ( p < 0.05) in the SS group. On the other hand, SS were more related to limb length discrepancy (61% vs. 33%; p < 0.05). No major complications were recorded in the 2 groups. Conclusion: Short stems were shown to be comparable or better than traditional implants at short-term follow-up.

Purpose: The purpose of this study was to report the long-term results of total hip arthroplasty (THA) for the treatment of ankylosed hip. Methods: Twenty-nine consecutive THAs were performed in 26 patients. The mean age of the patients at the time of the operation was 43.3 years (range, 19–69 years). We used cementless fixation in all hips and the mean duration of follow-up was 10.1 years (range, 4.5–20 years). Radiological evaluation of components, osteolysis, radiolucent lines and loosening were assessed. The Harris Hip Score (HHS), range of motion (ROM), limb-length discrepancy and walking capacity with or without any support were used preoperatively and at final follow-up for clinical evaluation. Survivorship analysis was conducted using the Kaplan–Meier method using second revision for any reason as the endpoint. Results: The mean HHS was 85.6 (range, 55–98) points and mean ROM was 110.5° for flexion. The mean limb-length discrepancy improved from 4.1 cm to 1.1 cm. Positive Trendelenburg sign was recorded in 31% of the patients and 24% of patients needed any support for walking postoperatively. We observed surgical complications related to abductor arm in 25% of the patients. Radiolucency on the acetabular side was seen on one or more zones in 15 patients (16 hips). One aseptic acetabular component loosening was observed. On the femoral side, 11 patients demonstrated non-progressive radiolucent lines and osteolysis around the stem was seen in four hips but there was no aseptic stem loosening. The Kaplan–Meier survival rate considering revision for any reason as the endpoint was 81.5%, for aseptic loosening 91.3%, for a worst-case scenario of 66.4% at 10 years. Conclusion: Cementless fixation showed good to excellent results at 10 years. Preoperative and postoperative abductor status of the patient is critical for patient satisfaction.

Abstract Background: Congenital pseudarthrosis of the tibia (CPT) is a refractory and rare disease. Because of its extremely low incidence, little is known about its clinical features. In this retrospective study, the aim of this study was to analyze the clinical characteristics of patients with CPT. Methods: This is a retrospective study of children with CPT identified by radiological review. Investigations of CPT included general condition, the characteristics of CPT, treatment methods and surgical complications. Results: We have collected 514 CPTs from 1999 to March 2020 in our hospital, 317 (61.67%) boys, 197 (38.33%) girls; 330 (62.86%) in Crawford IV; 510 (97.14%) in mid and distal 1/3 tibia; 481 (93.58%) in less than 3 years of first appearance of symptom; 297 (57.78%) in less than 3 years of the first visit of outpatient. The most common postoperative complication was ankle valgus (101, 39.60%), followed by limb length discrepancy（91, 35.69%), refracture (38, 14.90%), osteomyelitis (15, 5.88%) and removal of internal fixation (10,3.93%) . Conclusions: CPT with higher incidence of Crawford IV frequently occurs in boys and middle or distal part of the tibia; most patients have the first appearance of symptom and the first visit of outpatient before 3 years; the major surgical complications were ankle valgus and limb length discrepancy.

Abstract Background The current surgical treatment of choice is the combination surgical technique, involving tibial intramedullary fixation to maintain the mechanical axis and mechanical stability of tibial pseudarthrosis. In traditional combined surgery, the Williams rod is often used. Long-term intramedullary fixation of the foot and ankle will affect the ankle joint function of children. The intramedullary rod is relatively shorter due to the growth of the distal tibia. In addition, there are some complications such as epiphyseal bone bridge and high-arched foot. The use of a telescopic intramedullary rod may avoid these complications. Purposes To investigate the initial effect of the “telescopic rod” in a combined surgical technique for the treatment of congenital pseudarthrosis of the tibia in children. Methods A retrospective study including 15 patients with Crawford type IV CPT who were treated using a combined surgical technique and the telescopic rod from January 2017 to May 2018. The average age at the time of surgery was 43.3 months (16–126 months). Of the 15 patients, 7 had proximal tibia dysplasia and 12 exhibited neurofibromatosis type 1. The combined surgical technique using the telescopic rod included the excision of pseudarthrosis, intramedullary rod insertion, installation of Ilizarov’s fixator, tibia-fibular cross union, and wrapping autogenic iliac bone graft. The incidence of refracture, ankle valgus, tibial valgus, and limb length discrepancy (LLD) in patients were investigated. Results All patients achieved primary union with an average follow-up time of 37.3 months (26–42 months). The mean primary union time was 4.5 months (4.0–5.6 months). Nine cases showed LLD (60%), with an average limb length of 1.1 cm (0.5–2.0 cm). Ankle valgus, proximal tibial valgus, telescopic rod displacement, and epiphyseal plate tethering occurred in 1 case (6.6%) (18°), 3 cases (20%) (10°, 5°, and 6°, respectively), 6 cases (40%), and 2 cases (13%), respectively. There were no refractures during the follow-up periods. Conclusion Although there are complications such as intramedullary rod displacement while using the telescopic rod in a combined surgery, the primary healing rate of congenital pseudarthrosis of the tibia in children is high.

Background: Congenital pseudarthrosis of the tibia (CPT) is a rare condition. The natural history of CPT includes persistent instability and progressive deformity. Several CPT treatment methods have been practiced, however, in Africa where there is scarce information on the modalities of treatment available and their outcomes. Methods: A retrospective cross-sectional study which was conducted among patients with CPT at Beit Cure International Hospital (BCIH), Malawi. Forty-four patients were recruited in this study and their treatment modalities and outcomes were analyzed. Results: Out of 44 patients recruited in this study, majority (63.6%) were male. The majority of cases were stage 4 congenital tibia pseudarthrosis by Crawford classification. Most patients were treated by more than one surgical modality; however, surgical excision and intramedullary rodding was commonly used (54.7%). The outcomes of treatment were good in 5%, fair in 30%, with amputation in 45% and poor outcomes in 20% of the patients. Complications developed in 60% of patients, predominated by limb length discrepancy. The foot and ankle status were rated by Oxford Foot and Ankle scoring system (OxFAQ). Conclusions: Congenital pseudarthrosis of the tibia is a complex congenital disorder with multiple modalities of treatment. Majority of the patients were treated by more than one operation. Some patients ended up with amputation or poor outcome. Limb length discrepancy, deep infection and pin tract infection are among the common complications. Keywords: congenital pseudarthrosis; tibia; treatment outcomes; Malawi

Limb length discrepancy (LLD) is a common problem after joint-preserving hip surgeries, hip dysplasia, and hip deformities. Limping, pain, sciatica, paresthesia, and hip instability are common clinical findings and may necessitate limb-lengthening procedures. The study included five patients (two female and three male, mean age of 28 years (20–49; SD: 12)) with symptomatic limb length discrepancy greater than 2.5 cm (mean: 3.6 cm) after total hip arthroplasty (THA), hip dysplasia, or post-traumatic hip surgery. They underwent either ipsi- or contralateral intramedullary limb-lengthening surgeries using the PRECICE™ telescopic nail. All patients achieved complete bone healing and correction of the pelvic obliquity after intramedullary lengthening. None of the patients had a loss of proximal or distal joint motion. The mean distraction-consolidation time (DCT) was 3.8 months, the distraction index (DI) 0.7 mm/day, the lengthening index (LI) 1.8 months/cm, the consolidation index (CI) 49.2 days/cm, the healing index (HI) 1.1 months/cm, and the modified healing index (HI*) 34 days/cm. Intramedullary limb lengthening after LLD in cases of hip dysplasia, hip deformity, and various kinds of hip surgery is a useful and safe procedure in young patients to achieve equal limb length. No functional impairment of the preceded hip surgery was seen.

AimsThe aim of this study was to describe, analyze, and compare the survival, functional outcome, and complications of minimally invasive (MI) and non-invasive (NI) lengthening total femoral prostheses.Patients and MethodsA total of 24 lengthening total femoral prostheses, 11 MI and 13 NI, were implanted between 1991 and 2016. The characteristics, complications, and functional results were recorded. There were ten female patients and ten male patients. Their mean age at the time of surgery was 11 years (2 to 41). The mean follow-up was 13.2 years (seven months to 29.25 years). A survival analysis was performed, and the failures were classified according to the Modified Henderson System.ResultsThe overall implant survival was 79% at five, ten, and 20 years for MI prostheses, and 84% at five years and 70% at ten years for NI prostheses. At the final follow-up, 13 prostheses did not require further surgery. The overall complication rate was 46%. The mean revision-free implant survival for MI and NI prostheses was 59 months and 49 months, respectively. There were no statistically significant differences in the overall implant survival, revision-free survival, or the distribution of complications between the two types of prosthesis. Infection rates were also comparable in the groups (9% vs 7%; p = 0.902). The rate of leg-length discrepancy was 54% in MI prostheses and 23% in NI prostheses. In those with a MI prosthesis, there was a smaller mean range of movement of the knee (0° to 62° vs 0° to 83°; p = 0.047), the flexion contracture took a longer mean time to resolve after lengthening (3.3 months vs 1.07 months; p < 0.001) and there was a lower mean Musculoskeletal Tumor Society (MSTS) score (24.7 vs 27; p = 0.295).ConclusionThe survival and complications of MI and NI lengthening total femoral prostheses are comparable. However, patients with NI prosthesis have more accurate correction of leg-length discrepancy, a better range of movement of the knee and an improved overall function.

Objective: To demonstrate the efficacy of locking plate osteosynthesis performed by an L-shaped lateral approach in patients with Sanders type III and IV intra-articular calcaneal fractures with posterior facet displacement. Methods: Fifty-three patients with Sanders type III or IV unilateral calcaneal fractures treated with locking plates and additional bone grafting were included in the study. Böhler and Gissane angles, and heel height values were measured on the radiological examinations. Clinical results of the patients were evaluated using the American Orthopaedic Foot and Ankle Society and Maryland evaluation criteria. The presence of arthrosis was investigated with Broden’s view. Preoperative and postoperative values were evaluated. Results: The mean Gissane angle was 119.32°, the mean Böhler angle was 9.47° and the mean heel height was 40.82 mm on radiographs at initial presentation of the patients. The mean Gissane angle was 114.63°, the mean Böhler angle was 23.33° and the mean heel height was 47.84 mm on the early postoperative radiographs of the patients. In patients, a mean 4.69° recovery was achieved in the Gissane angle, 13.86° in Böhler angle and 7.02 mm in heel height. On the most recent follow-up, Böhler angle was 21.49°, Gissane was 114.88° and the mean heel height was 46.95 mm. The mean American Orthopaedic Foot and Ankle Society score and Maryland score were 86.91 and 86.53, respectively, on the last follow-up. Conclusion: Internal fixation and grephonage using low-profile locking plates provides good functional results to patients since it facilitates anatomic restoration of the subtalar joint and correction of calcaneal height, width and varus/valgus heel.
