Introduction. The use of thoracic pedicle screws for the treatment of adolescent idiopathic scoliosis (AIS) has gained widespread popularity. Many techniques has been described to increase the accuracy of free hand placement; however the placement of pedicle screws in the deformed spine poses unique challenges because of possible neurologic and vascular complications. We are describing a universal way of insertion of pedicle thoracic screws which has been applied in many pathologies including the deformed spine. Methods. Our technique includes exposure of the superior facet of the corresponding body to identify its lateral border border which together with the superior border of the TP denotes our entry point which is just lateral to this crossing, we make a short entry with a straight Lenke probe then continue the track with a strong ball probe to go safely through the cancellous bone of the body. This is retrospective review of radiographs and clinical notes of all the patients who underwent posterior thoracic instrumentation by pedicle screws using the same single technique by one surgeon between June 2008 and December 2009; 1653 screws in 167 consecutive patients (119 females and 48 males). There were 139 deformities, 130 scoliosis (AIS 80, Congenital 31, Neuromuscular 10 and Degenerative 9), 19 kyphosis and 18 other diagnoses (fractures 14, revision 3 and tumour 1). Results. The recorded complications for all the patients were: 1 patient had pain due to nerve impingement, 1 parasthesia and 1 CSF leak intraoperatively. There were no revision of any of the screws, no vascular complications. Conclusion. Thoracic pedicle screws can be inserted with a universal point of entry using the same technique in all the levels of the dorsal spine. This technique seems to be simple and safe. Ethics approval: None. Interest Statement: None

Aim and method We report the outcomes of 100 consecutive diabetic patients who had been prescribed diabetic footwear for 10 years. A podiatrist and orthotist reviewed them at a dedicated clinic. The study aim was to assess footwear efficacy and prevention of ulcers, re-ulceration and amputations. Conclusion Protective footwear is essential in maintaining healthy diabetic feet. Amputations were only due to vascular complications. All 56 patients who attended remained intact at 2 years. Of the seven ulcerations at 5 years, three went onto below-knee amputation. At 10 years, there were a further three ulcerations, resulting in one minor black toe and one further BK amputation. Adherence with follow up including footwear review minimises risk. Re-ulceration at 5 years is associated with risk of amputation. Ten-year mortality is high due to vascular complications. Summary Continued patient adherence with Orthotic therapy confers benefit and minimised re-ulceration. Follow up by Orthotists is an under-utilised resource

Talectomy was performed on 31 rigid clubfeet in 13 boys and 10 girls. Sixteen patients had myelomeningocele and seven arthrogryposis. The procedure was undertaken as a salvage operation on 22 feet. Seven patients had an additional cuboidectomy. The mean age of the patients was 3.7 years (2 to 9). The patients were followed up for a mean of 4.5 years. Assessment included foot position, appearance and mobility, orthotic or shoe-wear fitting and walking capacity. Calcaneal position at the ankle was assessed radiologically. The results in 18 feet were good and in seven were satisfactory. There were six failures. Primary talectomy produced better results in children above the age of two years than ssecondary procedure in the older children. One of the patients developed a severe vascular complication, followed by sepsis, and required amputation of the foot. The other failures were due to recurrence of equines deformity. Talectomy performed for severe rigid clubfoot achieved satisfactory correction in most of our patients. Excision of the talus as a salvage procedure carries a risk of incomplete correction and vascular complication

Purpose: Vascular complications in lumbar disc surgery are rare, difficult to diagnose and may have serious consequences. We review our experience in eight cases treated in the past 30 years. Methods: Between 1976 and 2005 we operated on 16,391 cases of vascular pathology, eight for vascular complications after lumbar discectomy (herniated disc), six men and two women aged 36 to 70 (mean 52 years). The symptoms were abdominal pain in four, ischial irradiation in one, episodes of heart failure in one, limb oedema in two, acute haemorrhage in three, abdominal murmur in two. The diagnosis was made during surgery in two cases and immediately postoperative in the third due to severe hypovolemia. The others were diagnosed because of abdominal murmur, limb oedema and suspected abdominal aneurism. Abdominal CT scans and arteriography were performed in five cases. Treatment was surgical, with direct closure in seven cases and interposition of a Dacron aortoiliac prosthesis in the other. No sequelae were seen during follow-up, which lasted a maximum of fifteen years. All the patients returned to normal life and there was no mortality. Conclusions: Because of the severity and rareness of this complication, few cases have been described in the literature, and its real incidence is therefore unknown. We should think of it whenever there is any unexplained, sustained haemodynamic disorder during lumbar disc surgery or immediately postoperative. Treatment should be immediate

Aim: Vascular complications associated with locked intramedullary tibial nailing are rare but always serious. The purpose of this cadaveric study is to define the risk of vascular complications after proximal locking in intramedullary tibial nailing. Material and Methods: Seven fresh cadaver legs were obtained from the University Hospital of loannina. The Grosse & Kempf Tibial Locking Nail was used with anterior-posterior locking. Each procedure was performed according to a standard protocol. The insertion point of the tibial nail was just above the level of the tibial tuberosity. The direction of the proximal locking screw was oblique from caudal to cranial and from lateral to medial. For imaging, both the nail and screws were removed and titanium screws were inserted, thereby allowing good visualization. Results: MRI sections combined with CT and 3D-CT have been used to illustrate the findings, as they clearly demonstrate the relationships between the locking screws and adjacent vascular structures. Analysis of these findings highlighted the surgical risks associated with this type of proximal locking and its direction. Conclusions: Proximal anterior-posterior locking in intramedullary tibial nailing is a hazardous procedure because of the small distance between tibia and vascular structures. The use of a new direction for proximal anterior-posterior locking is recommended

Purpose: Vascular complications associated with locked intramedullary tibial nailing are rare but always serious. The purpose of this cadaveric study is to deþne the risk of vascular complications after proximal locking in intramedullary tibial nailing. Methods: Seven fresh cadaver legs were obtained from the University Hospital of Ioannina. The Grosse & Kempf Tibial Locking Nail was used with anterior-posterior locking. Each procedure was performed according to a standard protocol. The insertion point of the tibial nail was just above the level of the tibial tuberosity. The direction of the proximal locking screw was oblique from caudal to cranial and from lateral to medial. For imaging, both the nail and screws were removed and titanium screws were inserted, thereby allowing good visualization. Results: MRI sections combined with CT and 3D-CT have been used to illustrate the þndings, as they clearly demonstrate the relationships between the locking screws and adjacent vascular structures. Analysis of these þndings highlighted the surgical risks associated with this type of proximal locking and its direction. Conclusions: Proximal anteriorposterior locking in intramedullary tibial nailing is a hazardous procedure because of the small distance between tibia and vascular structures. The use of a new direction for proximal anterior-posterior locking is recommended as an alternative procedure to eliminate the potential for iatrogenic lesions

Study design: A retrospective evaluation of screw position after double rod anterior spinal fusion in idiopathic scoliosis using computerised tomography (CT). Objective: To evaluate screw position and complications related to screw position after double rod anterior instrumentation in idiopathic scoliosis. Summary of Background Data: Anterior instrumentation and fusion in idiopathic scoliosis is gaining widespread use. However, no studies have been published regarding the accuracy of screw placement and screw related complications in double rod and double screw anterior spinal fusion and instrumentation in idiopathic thoracolumbar scoliosis surgery. Methods: CT examinations were performed after anterior spinal fusion and instrumentation in 17 patients with idiopathic scoliosis. The vertebral rotation at each level was measured. At each instrumented level the position of the screw and the plate relative to the spinal canal, relative to the neural foramen and relative to the aorta was measured. Complications related to screw position were registered. Results: 189 screws in 17 patients were evaluated. The average age of the patients was 31 years (range 15–53 years). Fourteen patients had a left convex thoracolumbar curve and three patients a right convex thoracolumbar curve. The mean lumbar apical rotation preoperatively was 27°. Malposition occurred in 23% of the total number of screws. Three screws were in the spinal canal (1%). This resulted in pain in the right leg. However, electromyography showed no abnormalities. On three levels there was contact between the instrumentation and the aorta. No vascular complications did occur. 113 screws (ten patients) were placed under fluoroscopic guidance and 76 screws (seven patients) were placed without use of fluoroscopy. No complications related to screw position were observed in the group in which the screws were placed under fluoroscopic guidance. Conclusions: Adequate placement of two screws in the vertebra in idiopathic scoliosis is a technically demanding procedure, which results in frequent malposition, fortunately with a low risk of neurological and vascular complications

Purpose of the study: To analyse 300 supracondylar fractures with major displacement presenting with acute vascular comprimise and to propose an effective therapeutic strategy in a tertiary referral centre. Material and Methods: Three hundred patients aged 18 months to 14 years were treated for Larange stage IV supracondylar fracture of the humerus in the same centre. Acute vascular compromise was noted in 46 cases (15%). The radial pulse was absent in all patients with two different contexts: ‘pink hand’ with good distal perfusion in 41 cases (13.5%) and ‘white hand’ with ischemia in five cases (1.5%). Nerve injury was associated in half of the cases, predominantly involving the medial nerve (87%). Emergency management included repeated assessment of the vascular and nervous status using a departmental protocol and Doppler control together with oxygen saturation. Emergency anatomical reduction and stable percutaneous fixation, with lateral and medial wires via a minimal medial exposure to control the ulnar nerve, was performed in all cases. Post-operative immobilisation with a posterior splint at 90° of elbow flexion. Repeated postoperative clinical surveillance: distal perfusion, O2 saturation and Doppler assessment. Results: 90% of the cases with vascular compromise had posterolateral displacement. Post reduction, the radial pulse was restored immediately in 28 cases and secondarily in 10. The three remaining cases with an absent radial pulse but with a pink hand developed ischemia necessitating surgical exploration revealing incarceration of the brachial artery and medial nerve within the fracture site. Release of the brachial artery restored the radial pulse. The five cases of primary ischemia with absent pulse and a white hand were managed by emergency reduction followed by exploratory surgery and vascular repair which restored the radial pulse, excepting one case which required anterior fasciotomy. Conclusion: Early vascular complications after stage IV supracondylar humerus fractures are common in children. This study identified the following points: priority is required for reduction of these fracture and emergency stabilisation; posterolateral displacement is associated with a higher risk of vascular complications; these injuries should be treated in a specialised centre; the absence of a radial pulse with a pink hand warrants repeated observation during the postoperative period; it is not an absolute indication for invasive investigation and surgical exploration; the absence of a pulse with a white hand requires surgical vascular exploration

Purpose of the study: The rate of intra and postoperative complications is generally high after surgery for neurogenic paraosteoarthropathy, also termed hetero-topic ossification. Material and methods: We present a series of 60 cases of osteoma involving the hip joint, analyzing complications in comparison with data in the literature. Results and discussion: Vascular complications (n=7): one required suture of the common femoral artery, three ligature of the deep femoral artery, two ligature of the deep femoral vein and one ligature of the collateral branches of the deep femoral vessels. Mean intraoperative blood loss was 1300 cc. None of the vascular complications gave rise to death or amputation. Early septic complications (n=4): three occurred after simple resection of the ossification and cured after surgical revision and antibiotics with no major impact on joint motion; one occurred after a procedure for resection of the ossification plus total hip arthroplasty and led to ankylosis of the hip joint but cured after surgical revision and prolonged antibiotic therapy. Sepsis was favored by a long hemorrhagic surgical procedure in patients at risk. Neurological complications (n=0): such complications are greatly feared but rare. Posterior ossifications expose the sciatic nerve to injury but generally displacement the nerve rather than enclosing it in the osteoma. Fracture complications (n=1): the outcome was favorable, both in terms of bone healing and joint motion. A classical complication mentioned in the literature and synonym to recurrent ossification or invalidating residual stiffness. Most are favored by ankylosis, osteoporosis, immobilization and a particularly dynamic surgeon. Recurrences (n=6): all were posttraumatic with a delay from accident to surgery ≥ 18 months. Conclusion: Complications are related to the localization of the osteoma (relations with nerves and vessels), associated osteopathy, and the complete or partial joint stiffness. Preoperative imaging (x-rays and computed tomography with contrast injection) should localize the osteoma, keeping in mind that certain localizations create preferential conditions for certain risks. An analysis of the topography of the paraosteoarthropathy should enable the surgeon to choose the most appropriate approach. Intraoperatively, risk assessment can usefully anticipate complications which always compromise functional outcome

Aims

Ilium is the most common site of pelvic Ewing’s sarcoma (ES). Resection of the ilium and iliosacral joint causes pelvic disruption. However, the outcomes of resection and reconstruction are not well described. In this study, we report patients’ outcomes after resection of the ilium and iliosacral ES and reconstruction with a tibial strut allograft.

Methods

Medical files of 43 patients with ilium and iliosacral ES who underwent surgical resection and reconstruction with a tibial strut allograft between January 2010 and October 2021 were reviewed. The lesions were classified into four resection zones: I1, I2, I3, and I4, based on the extent of resection. Functional outcomes, oncological outcomes, and surgical complications for each resection zone were of interest. Functional outcomes were assessed using a Musculoskeletal Tumor Society (MSTS) score and Toronto Extremity Salvage Score (TESS).

Purpose: The bifoliated vascularised fibula graft is an attractive alternative for reconstruction of large bone segments. The purpose of this work was to evaluate mid-term results and the usefulness of two surgical techniques: skin island flap monitoring and the arterio-venous loop. Material and methods: This retrospective analysis included fourteen patients (eleven men and three women) treated between 1992 and 2002. Mean age was 30 years (10–54). Indications were complications of open fractures in nine patients, major bone loss in two, septic nonunion in four, and aseptic nonunion in three. Reconstruction was performed after bone tumour resection in five patients involving immediate reconstruction after failure of an infected massive allograft in four of them. Localisations were: tibia (n=6), femur (n=5), humerus (n=2), and pelvis (n=1). Average bone loss was 10 cm (7–15 cm). Minimal pinning, cerclage or screwing was used to stabilise the flap completed by internal fixation in four patients and external fixation in ten. A monitoring skin island was used for twelve patients (the island was technically impossible in two patients). Vascular anastomoses were performed in seven patients using an arteriovenous loop, performed as a preliminary measure in six. Results: Mean follow-up was 35 months. One patient died early from tumour progression. Among the seven patients who had an arteriovenous loop, one required revision for a vascular complication. For the seven “classical” bypasses, there were three intraoperative or early complications requiring revision of the anastomoses. Nonunion developed despite early revision in the four patients whose monitoring skin island suffered. Consolidation was achieved without revision in all patients who skin island did not suffer; time to bone healing was eleven months for seven of them. Conclusion: Bone healing was related to the quality of graft vacularisation. Clinical observation of the monitoring island was the best way to identify vascular complications early and initiate treatment. Use of a preliminary arteriovenous loop decreased the risk of vascular insufficiency inherent with long bypasses and shortened operative time

Aims

To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration.

Methods

We performed a systematic literature search in MEDLINE, Embase, and Web of Science. The search string included multiple synonyms of the following keywords: "revision TKA", "outcome" and "prognostic factor". We searched for studies assessing the association between at least one prognostic factor and at least one outcome measure after rTKA surgery. Data on sample size, study design, prognostic factors, outcomes, and the direction of the association was extracted and included in an evidence map.

Aims

Developmental dysplasia of the hip (DDH) describes a pathological relationship between the femoral head and acetabulum. Periacetabular osteotomy (PAO) may be used to treat this condition. The aim of this study was to evaluate the results of PAO in adolescents and adults with persistent DDH.

Methods

Patients were divided into four groups: A, adolescents who had not undergone surgery for DDH in childhood (25 hips); B, adolescents who had undergone surgery for DDH in childhood (20 hips); C, adults with DDH who had not undergone previous surgery (80 hips); and D, a control group of patients with healthy hips (70 hips). The radiological evaluation of digital anteroposterior views of hips included the Wiberg angle (centre-edge angle (CEA)), femoral head cover (FHC), medialization, distalization, and the ilioischial angle. Clinical assessment involved the Harris Hip Score (HHS) and gluteal muscle performance assessment.

Introduction. Periacetabular osteotomy has been described as an effective way of treating symptomatic hip dysplasia. We describe a new minimally invasive technique using a modification of the Smith Peterson approach. Patients/Materials & Methods. 189 consecutive patients operated on between March 2010 and March 2013 were included in the study. Patients who had undergone previous pelvic surgery for DDH were excluded. There were 174 females and 15 males. The mean age was 31 years (15–56) and the mean duration of follow-up was 29 months (14 – 53 months). 90% of cases were Tonnis grade 0 or 1. Twenty-three patients were operated on for primary acetabular retroversion. Functional outcomes were assessed using the NAHS, UCLA and Tegner activity scores. The surgical procedure is performed through an 8–10 cm skin crease incision; a soft tissue sleeve is elevated from the anterior superior iliac spine. The interval medial to the rectus femoris is developed. The hip joint is not opened and fixation of the osteotomy was with three 4.5mm cortical screws. A cell saver was routinely used. Results. For the dysplasia group the mean pre-operative lateral centre edge angle was 14.2degrees (−5degrees to 30degrees) and the mean acetabular index was 18.4degrees (4degrees to 40degrees). Post-operatively these were 31degrees (18degrees to 46degrees) and 3degrees (−7degrees to 29degrees) respectively. An allogenic blood transfusion was required in 3 patients (1.5%). The mean duration of surgery was 105 minutes. There were no major nerve or vascular complications and no wound infections. At the time of last follow-up, we noted a significant improvement in functional outcome scores: UCLA improved by 2.31 points, Tegner improved by 1.08 points, and the NAHS improved by 25.4 points. Conclusion. We have found this approach to be safe and effective, facilitating early recovery from surgery

Background. Intravenous and topical tranexamic acid (TXA) has become increasingly popular in total joint arthroplasty to decrease perioperative blood loss. In direct comparison, the outcomes and risks of either modality have been found to be equivalent. In addition, current literature has also demonstrated that topical TXA is safe and effective in the healthy population. To our knowledge, there is a scarcity of studies demonstrating the safety of topical TXA in high risk patient populations undergoing total joint arthroplasty or revision joint arthroplasty. The purpose of this study is to determine the safety of topical TXA in patients undergoing total or revision arthroplasty that are also on chronic anticoagulant or anti-platelet therapy. Methods. We performeded a retrospective review of patients undergoing primary and revision total hip or knee arthroplasties that received topical TXA (3g/100mL NS) from November 2012 to March 2015. All patients, regardless of co-morbidities, were included in the study population. Patients were divided into 3 groups:. Group 1: Patients without any antiplatelet or anticoagulant therapy within 90 days of surgery. Group 2: Patients receiving antiplatelet therapy (Aspirin and/or Plavix) within 90 days of surgery. Group 3: Patients receiving anti-coagulant therapy within 90 days of surgery (low molecular weight heparin, unfractionated heparin, warfarin, dabigatran, rivaroxaban, apixaban). Chart review analyzing ICD-9 and ICD-10 coding was then utilized to establish any peri-operative complications within the 30 day post-operative period in all groups. Complications amongst the groups were evaluated via chi-squared testing as well as multivariate linear regression. Review of current literature and CMS protocols were used to establish reportable peri-operative complications. Wound infections, thromboembolic events and vascular complications such as myocardial infarction, pulmonary embolism, deep venous thrombosis, stroke, aortic dissection were included. Results. During the study period, a total 1471 total joint arthroplasties were performed on 1324 patients (88.7% knee arthroplasty, 11.3% hip arthroplasty). Group 1 included 1033 patients who were not on any prior anti-platelet or anticoagulant therapy. Group 2 included 254 patients receiving chronic antiplatelet therapy 90 days prior to surgery. Group 3 included 184 patients receiving chronic anticoagulant therapy 90 days prior to surgery. No statistically significant differences were found between the groups for any of the included peri-operative complications. The most common complication occurring amongst all the groups was superficial wound infection, which occurred in a total of 60 (4.1%) patients in contrast to 18 (1.2%) patients who sustained an acute deep peri-prosthetic infection. Twenty (1.4%) patients sustained an ultrasound proven deep vein thrombosis, with the highest prevalence occurring in those patients receiving no anticoagulation prior to surgery (15/20, 75%), however this was not statistically significant following linear regression analysis. Conclusions. To our knowledge, this is the first study that demonstrates that topical tranexamic acid is safe to use in so-called high risk patients who are being treated prior to surgery with anti-platelet or anti-coagulation therapy

Introduction. Femoral neck fracture is a common injury in elderly patients. To restore the activity with an acceptable morbidity and to decrease of mortality, surgical procedures are thought to be superior to conservative treatments. Osteosynthesis with internal fixation for nondisplaced type, and hemiarthroplasty or total hip replacement (hip arthroplasties) for displaced type are commonly performed. Cemented arthroplasty has been preferred over non-cemented arthroplasty because of less postoperative pain, better mobility and excellent initial fixation of the implant, especially for osteoporotic and stove-pipe bones. However, pressurizing bone cement may cause cardiorespiratory and vascular complications, and occasionally death, which has been termed as “bone cement implantation syndrome”. To avoid the occurrence of this syndrome, non-cemented implants have been developed. However, most implants with the press fit concepts and flat wedge taper designs have a risk of intraoperative and early postoperative periprosthetic fracture. Recently, we have employed a non-cemented femoral component, which has a lateral expansion to the proximal body as compared to a conventional hip stem. Because of this shape, which is called a “lateral flare”, this stem provides a physiological loading on both the medial and lateral endosteal surfaces of the femur. This is in contrast to conventional hip stem which prioritizes loading on the medial and metaphyseal /dyaphyseal surfaces of the femur. Moreover, the cross section of this stem is trapezoid with the flat posterior surface. This shape provides the stem with rotational stability along the long axis of the femur, and maximizes loading transfer to the posterior aspect of the proximal femur. These mechanical features avoid the need for aggressive impaction of the stem at the time of insertion. It is necessary to only tap gently to achieve the secure initial implant fixation by a “rest fit”. Thus, this technique reduces the risk of fracture. Patients and methods. We employed this technique using a non-cemented lateral flare design device for displaced femoral neck fractures since 1996. Surgical procedures were performed with posterior approach under the spinal or epidural anesthesia. Full weight bearing ambulation with a walker was allowed on post-op day one. Results and discussion. Since that time, we have had no femoral fracture, no dislocation of the hip, nor severe complications intraoperatively and post operatively. There has been no evidence of radiographic aseptic loosening or axial migration of the stems during this time period. Conclusions. “Rest fit” surgical technique avoids complications associated with cemented and traditional non-cemented arthroplasties for displaced femoral neck fractures. It however requires specific geometric features to be included the designs of the femoral component to assure secure initiate fixation at the time of arthroplasty. Therefore, this lateral flare implants are effective for the treatment of the displaced type of femoral neck fracture

Introduction. Corrective femoral osteotomy in adults, as a closed procedure with the use of an intramedullary saw, is an elegant, minimally invasive technique for the correction of lower limb length inequalities or problems of torsion. Stabilisation following the osteotomy was achieved with a cephalo-medullary nail. We report the indications, results and complications following use of this technique. Aim. The aim of the study was to review consecutive patients who underwent closed femoral rotational or shortening osteotomy using an intramedullary saw over a ten-year period. Material & Methods. Forty femoral rotational and/or shortening osteotomies using an intramedullary saw were performed on thirty-six patients, between January 2001 and June 2011. The main indications were post-traumatic leg length discrepancies and congenital rotational abnormalities. Clinical & radiological follow up mean was 16.3 months. Results. Twenty one osteotomies were performed for femoral shortening with the mean correction of 3.5 cm. Nineteen osteotomies were performed for correction of torsion; there was a mean correction of 28.64 degrees with Internal rotation and 35 degrees with external rotation osteotomies. Fourteen patients required removal of locking screws. There were two patients with heterotrophic ossification, two patients with wound infection (one deep infection). One patient had a materiovigilance incidence and one patient had vascular complication requiring embolisation. The subjective results showed 37 osteotomies were satisfied with their operation, functional recovery and aesthetic appearance of the scars. Conclusion. Closed osteotomy of femur for correction of LLD and torsion using an intramedullary saw represents a reliable and effective procedure. Despite the complications, the original goal of the surgery was achieved in 37 of the 40 limbs treated. Patient satisfaction was achieved in 92.5 % of 40 osteotomies

I wish to present my experience with 521 patients with infection around hip arthroplasty and 262 with infected knee arthroplasty. The management in each case depends on circumstances such as the period since surgery, the patient’s symptoms, severity of illness and general health, and the condition of the remaining bone stock. One hundred and thirty hips and 94 knees were managed conservatively i.e. without surgery. Nine knees and 11 hips had debridement and irrigation without removing the arthroplasty. Infection persisted in 2 knees and 3 hips. Nine knees were exchanged in one stage. infection persisted in 5. Forty three hips were exchanged in one stage. Infection persisted in 18. Fifty knees were exchanged in two stages. Infection persisted in 11. One hundred and ninety eight hips were exchanged in two stages. Infection persisted in 28. Arthrodesis was performed in 77 of the more severely infected and destroyed knees. Infection persisted in 32. One hundred and eight of the more severely destroyed hips were left as excision arthroplasties. Ten remained infected but comfortable. Five patients required amputation above the knee and three through the hip. Two patients sustained serious vascular complications during surgery at the hip and one at the knee. Four patients in this series died during treatment

Data was collected on 139 eligible patients a minimum of 18 months post surgery who had had 2 or more ligaments reconstructed. 63 patients were available for clinical follow up. It is the largest single surgeon series studied. 27% of injuries were high energy traffic accidents. 73% were low energy, mainly sports related. 63% of patients were delayed referrals to our unit. Of these nearly 48% had already undergone knee surgery, often more than 6 months post injury. 17% of all cases presented with failed ligament reconstructions. Of those patients followed up 19% were operated upon within 3 weeks of injury, 56% were delayed reconstructions with a mean time to surgery of 21 months and 25% were revision reconstructions. Time to follow up ranged from 18 months to 10 years. The median KOS ADL, KOS Sports Activity and Lysholm scores for uni-cruciate surgery were all better than those for bi-cruciate surgery. All results were better for acute rather than chronic cases, which in turn were better than those for revision cases. The Tegner score showed that only acute uni-cruciate reconstructions returned to their pre-injury level. TELOS stress radiographs demonstrated a mean post drawer of 5.9 mm side-to-side difference after reconstructions involving the PCL. IKDC grades showed 6% of knees were normal and 57% were nearly normal. 37% required further surgery, mainly to increase movement or for hardware removal. There was 1 deep infection and 2 cases of thrombosis. There were no vascular complications but 2 had transient nerve injuries. Multi-ligament surgery can produce good functional outcomes but the knee is never normal. There is an increased risk of PCL laxity post op. Early referral to a specialist unit is suggested as delayed referral to a specialist unit potentially subjects the patient to unnecessary surgery and may affect outcome

Survivors of meningococcal septicaemia often develop progressive skeletal deformity secondary to physeal damage at multiple sites, particularly in the lower limb. Distal tibial physeal arrest typically occurs with sparing of the distal fibular physis leading to a rapidly progressive varus ankle deformity. There is no previous literature reporting this ankle deformity following meningococcal septicaemia. We report the management of this deformity in 13 ankles in 10 consecutive patients 36 months after meningococcal septicaemia. Plain radiographs and MRI were used to define the deformity and the extent of growth plate involvement. The Taylor Spatial Frame (TSF) with a distal tibial metaphyseal osteotomy was used to restore the distal tibio-fibular joint. Distal fibular epiphysiodesis was performed in all ankles at the initial procedure. Distal tibial epiphysiodesis was performed at the time of fixator removal. The age at operation ranged from 3–14 years (mean 8). The preoperative ankle varus deformity ranged from 9–29 degrees (mean 19). The differential shortening of the tibia with respect to fibula was on average 1.2 cms. The mean time in frame was 136 days. After a mean follow-up of 1.7 years results were excellent in all patients with complete correction of deformity and shortening. Mechanincal axis was corrected in all patients. Complications included, 4 superficial pin site infections, 1 lateral peroneal nerve palsy which recovered completely. There were no major nerve or vascular complications. We consider that this approach provides a powerful method of correction for this difficult group of patients
