Introduction. Orthopaedic rehabilitation of adolescences and young adults with high dislocation of the femur is rather challenging. The role of palliative salvage procedures is controversial enough in the cohort of patients. Materials and Methods. Treatment outcomes of 10 patients with congenital hip dislocation were analyzed. Mean age at intervention was 17,8 years (15–22). The grade of dislocation were assessed according to Eftekhar: type C − 2, type D − 8. The mean baseline shortening was 4.7±0.36 cm. All subjects underwent PSO with the Ilizarov method. Another osteotomy for lengthening and realignment was produced at the boundary of the upper and middle third of the femur. The mean time in the Ilizarov frame was 5.3 months. Results. The mean follow-up was 2.6±.1 years (range, 15 to 32 years). Limb shortening of 1 cm to 1. 1. /. 2. cm was observed in four cases. Functional outcomes according to d'Aubigne-Postel were: Pain 4,4±0,15 points. ROM − 4,1±0,3 points. Walking ability − 4,5±0,2 points. Two cases had good results (15–17 points), and seven patients had fair outcomes (12–14 points). A poor result (7 points) was recorded in one female patient 28 years after PSO followed by THA. Conclusions. Hip reconstruction with the Ilizarov method can be used in specific clinical situations as an alternative salvage procedure to delay THR in young patients with high dislocation of the femur

Introduction. Congenital posteromedial bowing of tibia (CPMBT) is characterized by a decreasing deformity and an increasing limb shortening. Our series compares the duration and complications of lengthening in younger vs older children. Materials and Methods. We studied 28 tibial lengthenings in 23 patients, divided into two equal groups of 14 segments: group-A ≤5 years (preschool) and Group-B >5 years. We measured preoperative (bo) and postoperative (po) sagittal, coronal, and oblique plane deformities, limb length discrepancy (LLD), amount of lengthening (AmtL), percentage lengthening (%L), external fixator duration (EFD) and external fixator index (EFI). Complications were graded by Lascombes’ criteria, results by ASAMI Bone score. Results. Mean age= 8.8 ± 7.1 years; mean follow-up= 7.9 years. Group-A had significantly greater bo-sagittal, coronal, and oblique plane deformities. LLD (3.4 cm in group-A vs. 4.1 cm in group-B) was similar in both. LLD at maturity (LLD. M. ) by multiplier method ranged 4.4–9.5 cm in group-A and 2.5–9.7 cm in group-B. Though AmtL (3.5 cm and 4.1 cm) was similar in both, %L was 24% in group-A and 15.7% in group-B (p=0.002). EFD (116.6 days) and EFI (33.7 days/cm) were lesser in group-A vs group-B (200.3 days, p=0.001; 50.2 days/cm, p=0.01). Lascombes’ criteria were fulfilled in 11/14 lengthenings in group-A vs. 3/14 in group-B. ASAMI bone score was good and excellent in both groups (p=0.44). Conclusions. Younger children with large deformities and LLD. M. could be safely lengthened with lesser external fixator duration and complications than in older children

The rate of periprosthetic joint infections (PJI) after primary total hip arthroplasty (THA) is approximately 1%. As the number of THAs performed each year continue to increase (550,000 by 2030), a corresponding increase in the number of hip PJI cases is likely to occur. A chronic deep infection may be treated by either chronic suppression, irrigation and debridement, single-stage exchange, or two-stage exchange. In the United States, the gold standard for chronic PJI continues to be a two-stage exchange. The benefit of an antibiotic impregnated cement is that they produce higher local concentrations of antibiotics than systemic intravenous administration. Hip spacers may be either static or articulating. Static spacers are reserved for cases of massive acetabular bone loss in which an articulating spacer is not feasible. A static spacer consists of a block of antibiotic cement in the native acetabulum and antibiotic coated rod in the femoral canal. Limb shortening, loss of soft tissue planes, and disuse osteopenia and muscle atrophy are all limitations of static spacers. In contrast, articulating spacers fulfill the goals of the interim construct during two-stage exchange which is to enhance eradication of the infecting organism through drug elution, to maintain limb length, to facilitate exposure during revision surgery, and to improve functional mobilization. Articulating spacers may be divided into three general categories based on method of spacer creation: Handmade custom spacers, prefabricated spacers, custom molded spacers (hemiarthroplasty molds and molded stem with cemented all-polyethylene cup). Handmade custom spacers are usually created with K-wire or rush rods coated with antibiotic cement. Handmade spacers are relatively simple to make, they are economical, and the amount and type of antibiotics incorporated can be customised for the infecting organism. Commercially available hemiarthroplasty spacers can be either prefabricated (Spacer G, Exactech, Gainesville. FL) or made intraoperatively (Stage One, Zimmer Biomet, Warsaw, IN) are available in several head and stem sizes. The advantage of prefabricated spacers is that they do not require additional time to mold in the operating room. The downside of prefabricated spacers is that the antibiotic concentration and type is predetermined. A custom molded stem with cemented all-polyethylene cup can be made with off the shelf implants or used as part of a commercially available spacer (PROSTALAC, DePuy Synthes, Warsaw, IN). A common antibiotic/cement combination includes Tobramycin (3.6 g/40 g of cement) and vancomycin (1.5 g/40 g of cement). In all of these spacer constructs, the principles of using a high-elution cement mixed without a vacuum and with high doses of heat stable antibiotics are consistent. Tobramycin works synergistically to improve Vancomycin elution properties and is usually added in higher doses. Overall infection eradication is similar between all categories of spacers and range between 90–97%. Complications after placement of an articulating spacer are often specific to the type of spacer used. Handmade spaces that have K-wires for support are at risk for spacer cement fracture. Spacer dislocation is also a common complication in up to 15% of cases with all types of spacers. In addition, periprosthetic fractures can occur postoperatively in up to 10% of patients. Overall, despite this complication profile, articulating antibiotic spacers have excellent rates of infection eradication and offer improved mobilization in the interim two stage period and reduce operative time, complexity, and morbidity during reimplantation

Autologous bone grafting for bone defect reconstruction is associated with complications including donor site morbidity, infection risk, pain and surgical time. Therefore, bone graft substitutes provide an alternative for distinct indications and different characteristics with regard to their mechanical properties and resorption rates. In order to fill the loss of bone substance and to control the infection, we tried the efficacy of Cerament™G, a new absorbable composite of Calcium Sulphate and Hydroxyapatite with Gentamicin. We present 3 male patients aged between 45 and 68 years affected by post-traumatic severe septic non union of femur, tibia and foot. The first patient with femur fracture was involved in a car accident (mixed flora Acinetobacter Baumanii, MRSA and Klebsiella pneumoniae carbapenemase (KPC)-producing), the second patient with femur and foot fracture falled by height in a work accident (MRSA) and the third one had a chronic tibial osteomyelitis several years after a road accident (Pseudomonas Aeruginosa). All 3 patients had undergone previous surgery. The first patient had several operations including multiple bone resection and debridement with external fixator, occlusion of superficial femoral artery with arterial bypass and finally debridement with implantation of Cerament™ G with external fixator and long term antibiotic therapy. The other 2 patients were subjected to resection of tissue septic with debridement, implantation of Cerament™ G and soft tissue closure and systemic antibiotics. Clinical and radiographic outcome were assessed at final follow-up (mean 8 months; range 8–18). The follow-up was 8–18 months with examining clinical, radiographic, CT scan and laboratory tests. The patients had self-limiting fluid leakage. There was no recurrence of infection during the follow-up period. Bone ingrowth occurred in all cases with limb shortening. Cerament™ G gives good elution of antibiotic and allows bone ingrowth. The implantation of Cerament™ G was associated with good clinical outcomes and satisfactory bone consolidation.

To present the results achieved with the use of external fixation techniques in treating 52 cases of post-traumatic and post-surgical septic non-union in a low resources setting. From 2006 to 2014 52 patients were treated for post-traumatic septic non-union of the lower and upper limb bones. Clinical records and radiographs were reviewed; telephone interviews were done for patients unable to reach our institution. There were 39 males and 13 females, with an average age at the time of admission of 29 years (the youngest patient was 8 years old, the oldest 81). Tibia was involved in 43 cases (24 right side, 19 left side), femur in 9 (4 right, 5 left) and left humerus in 1. All the patients, except two, had been treated in other institutions before admission. At presentation, 19 patients had an external fixator in situ, 18 patients had infected osteosynthesis, 15 had exposed necrotic bone, with loss of soft tissues. In 20 cases hardware removal, debridement and sequestrectomy were followed by application of an external fixator. In 31 cases bone transport was done; the fixator was monolateral in 27 cases. In 1 case sequestrectomy and external fixation were followed by a vascularized fibula graft. Bifocal bone transport was utilized in one patient while the bone transport procedure was associated to limb lengthening in 10 patients. Plastic surgery was required in 13 patients. Rotational flaps, vascularized free flaps and extensive skin grafts were all used. The site of non union was cured in all the patients, in an average time of 11 months (from 4 to 32). Two patients required an amputation a few months after the end of the treatment. There was need for fixator adjustment and screws replacement in 21 patients. Non-union at the docking point was observed in 5 patients; it was septic in two of them. There was need of skin-plasty in 2 cases for skin invagination. In 3 cases an extensive skin ulcer was observed during the transport procedure. Limb length discrepancy was corrected in 10 patients. A residual limb shortening was observed in 14 patients. Ankle fusion, knee fusion, foot drop, sensory loss in the foot, reduced range of joint motion were also observed. The external fixator plays a pivotal role in the treatment of septic non unions, especially in low resources setting. The treatment is long and costly. Strict medical supervision is necessary during the entire process

Aims

Chronic osteomyelitis (COM) of the lower limb in adults can be surgically managed by either limb reconstruction or amputation. This scoping review aims to map the outcomes used in studies surgically managing COM in order to aid future development of a core outcome set.

We report on the clinical, radiographic and functional outcomes after salvage arthrodesis for complex ankle and hind-foot problems - the Portsmouth experience with the Ilizarov ring fixator. 11 patients underwent ankle and hind-foot (tibio-calcaneal) arthrodeses using an Ilizarov ring fixator between 2006 and 2010. The indications included failed fusion after primary arthrodesis, sepsis complicating internal fixation of fractures, talar avascular necrosis and failed total ankle arthroplasty (TAR). All patients had undergone multiple previous surgeries, which had failed. There were 8 males and 3 females in this group. Average age of the patients was 58 (43 years – 77 years) Mean follow up was 36 months (7 – 60 months). Mean frame time was 24 weeks (15 – 36 weeks). BMP 2 (Inductos) was used in three cases. The procedure was combined with a proximal corticotomy and lengthening in 2 patients who had undergone a talectomy and tibio-calcaneal fusion. There were no major complications apart from minor pin site infections requiring oral antibiotics. There were no deep infections, thromo-embolic issues, CRPS, or functional problems on account of limb shortening. Patients were assessed clinically, radiologically and using functional outcome scores - EQ50 and AOFAS. Solid arthrodesis was achieved in all but one patient who was subsequently revised with a hind-foot nail. All patients were satisfied with their overall improvement in pain and function. We conclude that this is an effective salvage technique for complex ankle and hind-foot problems in patients with impaired healing potential, insufficient bone stock and progressive deformity

We evaluated the efficacy of using the expandable nail for treating non-union and malunion of the tibial and femoral shafts. Records of 20 patients were retrospectively reviewed: 12 had femoral non-union, 7 had tibial non-union, and one had tibial malunion. The bones underwent reaming and the largest possible nail sizes were inserted during reoperation. The mean age of the patients was 35 years (26-49) in the tibia group and 53 years (23-85) in the femur group. The fractures were defined according to AO/OTA classification and divided between open and closed. The initial treatment was 6 interlocking intramedullary nails and 2 external fixation in the tibia group, and 6 interlocking intramedullary nails, 3 plates and screws and 2 proximal femoral nails in the femoral group. The respective intervals between the original trauma and re-operation were 12 months and 15 months and the respective operation times were 59 minutes (35-70) and 68 minutes (20-120). All fractures healed satisfactorily without the need for an additional procedure. Healing time was 26 weeks (6-52) and 14 weeks (6-26) in the tibia and femur group, respectively. Limb shortenings of 10cm and 4cm were recorded in one patient each in the tibia group and of 3cm in one patient in the femur group. Using the expandable nail system permitted us to ream the bone and expand the nail to its maximal diameter, i.e. up to 16mm in the tibia and 19mm in the femur. We believe that using a bigger nail diameter contributes to better stabilisation of the fracture and promotes better and faster bone healing. Based on our experience, we recommend the use of the expandable nail system to treat tibia and femur shaft non-unions and malunions

Purpose. Rotationplasty was first described in 1930 by Borggreve for treatment of limb shortening with knee ankylosis after tuberculosis. In 1948, Van Nes described its use for management of congenital defects of the femur and in the 1980s, Kotz and Salzer reported on patients with malignant bone tumors around the knee treated by rotationplasty as an alternative to above-knee amputation. Currently, rotationplasty is one of the options for surgical management of lower extremity bone sarcomas in skeletally immature patients but alternative limb salvage techniques, such as the use of expandable endoprosthesis, are also available. Despite rather satisfactory functional results have been uniformly associated with rotationplasty, concern still exists about the potential psychological impact of the new body imagerelated to the strange appearance of the rotated limb. Results of rotationplasty for sarcomas of the distal femur over a 20-year period were analyzed, focusing on long-term survival, function, quality of life and mental health. Method. Retrospective study of 73 children who had a rotationplasty performed at two institutions between 1984 and 2007 for a bone sarcoma of the distal femur; 42 males and 31 females, mean age at surgery 8.7 yrs (range 3–17). Four patients were converted to transfemoral amputation due to early vascular complication; 25 eventually died of their disease (mean survival 34 months, range 4–127). The 46 remaining survivors were evaluated for updated clinical outcome, MSTS score, gait analysis, SF-36 score, quality of life interview and psychological assessment at mean follow-up of 15 yrs (range 3–23). Results. Overall survival was 64%. All the survivors were disease-free at last follow-up. Four patients required hardware revision for nonunion and subsequently healed. Three patients refused participation in the long-term follow-up study. Mean MSTS score was 79 (range 64–88). SF-36 score was obtained in 35 patients (age > 16); male patients showed a trend toward greater activity and vitality. Compared to age-group norms, rotationplasty scores were lower for physical activity level (p <0.05) and higher for general health perception (p = 0.05) and mental health (p < 0.05). Conclusion. Rotationplasty remains a durable reconstructive option with good long-term function and acceptable psychological impact for children with bone sarcomas of the distal femur
