Purpose of Study – The unusual presentation of this case posed a diagnostic dilemma between a chronic haematoma and soft tissue sarcoma even after full investigation and biopsy. Salient points to differentiate between the two are discussed along with literature review. Case Report – A 61 year old gentleman presented with sudden increase in size of an already existing swelling over the mid third of right leg associated with throbbing pain & foot drop of 4 months duration. There was no recent history of trauma or bleeding abnormalities but there was a vague history of injury to his leg during his late teens. Clinical signs showed features suggestive of malignancy with engorged veins and diffuse margins with complete foot drop (Fig 1 & 2). X-rays showed calcifications within the substance of the swelling along with proximal tibiofibular synostosis (Fig 3). MRI scan revealed a well encapsulated mass between the peroneal muscles mechanically compressing the common peroneal nerve (Fig 4). Trucut biopsy showed cholesterol clefts and areas of dystrophic calcification characteristic of chronic haematoma (Fig 5). Patient successfully underwent enucleation of the swelling along with cutaneofascial suture to obliterate the dead space leading to complete recovery of foot drop. Biopsy confirmed a Chronic Haematoma. Discussion – Reid et al first used the term chronic expanding haematoma for haematomas that persisted and increased in size more than a month after the initiating haemorrhage. The cause of initial haemorrhage is most commonly trauma which results in displacement of skin and subcutaneous fatty tissue from more deeply located fixed fascia with formation of blood filled cysts surrounded by dense fibrous tissue. Factors in the blood-clotting cascade are said to be associated with an inflammatory reaction leading to additional bleeding from fragile capillaries and thus to additional inflammation, hence setting up a self-perpetuating process. Although the MRI & biopsy results in this case were reassuring, the clinical scenario of sudden foot drop with increase in pain point more towards a malignant process rather than a benign condition. Some salient points to differentiate the two include that sarcoma have no history of trauma and the duration of symptoms is longer in haematoma than sarcoma. Also, sarcomas usually involve deeper structures while haematoma occur in superficial layers. It should also be noted that several soft tissue sarcoma themselves commonly reveal haemorrhagic or cystic changes. Other differential diagnosis includes myositis ossificans and tumoral calcinosis. Conclusion – It is difficult to differentiate between chronic haematoma and soft tissue sarcoma based on clinical findings alone. X-ray and biochemical tests are always essential to rule out any fracture or bony mass but MRI is the gold standard and biopsy is the only way to rule out a malignant tumour. Surgical excision of the swelling including the fibrous pseudocapsule along with cutaneofascial suture to obliterate the dead space is the treatment of choice for chronic haematoma because aspiration of the fluid or incomplete excision could lead to recurrence, continued growth or a chronic draining sinus with or without infection

Anesthetic peripheral nerve blocks (PNB) have been shown to be more advantageous than general anesthesia in a variety of surgical operations. In comparison to conventional methods of general anesthesia, the choice of regional localized infiltration has been shown to shorten hospital stays, decrease hospital readmissions, allow early mobilization, and reduce narcotic use. Perioperative complications of PNBs have been reported at varying rates in literature. Thus, the purpose of this study was to provide a review on the clinical evidence of PNB complications associated with foot and ankle surgeries. A systematic review of the literature was completed using PubMed search terms: “lower extremity”, “foot and ankle”, “nerve block”, and “complications”. All studies reporting minor and major complications were considered along with their acute management, treatments, and postoperative follow up timelines. The range of complications was reported for Sensory Abnormalities, Motor Deficits, Skin and systemic complications (local anesthetic systemic toxicity & intravascular injections). A designation of the scientific quality (Level I-IV) of all papers was assigned then a summary evidence grade was determined. The search strategy extracted 378 studies of which 38 studies were included after criteria review. Block complications were reported in 20 studies while 18 studies had no complications to report. The quality of evidence reviewed ranged from Level I to Level IV studies with follow up ranging from twenty four hours to one-three year timelines. The range of complications for all studies reporting sensory abnormalities was 0.53 to 45.00%, motor deficits 0.05 to 16.22% and skin and systemic complications 0.05 to 6.67%. Sensory abnormalities that persisted at last follow up occurred in six studies with incidence ranging from 0.23 to 1.57%. Two studies reported motor complications of a foot drop with an incidence of 0.05% and 0.12%. When considering only the highest quality studies (Level 1) that had complications to report, the complications rate was 10.00% to 45.00% for sensory abnormalities, 7.81 to 16.22% for motor deficits, 6.67% for skin complications and 2.50% for systemic complications. High quality studies (Level I providing Summary Grade A Evidence) reporting all complications with a range of incidence from 0 to 45%. While most of these complications were not serious and permanent, some were significant including sensory abnormalities, foot drop and CRPS. Based on this systematic review of the current literature, the authors emphasize a significant rate of complications with PNB and recommend that patients are appropriately informed prior to consenting to these procedures

Osteochondromas occur are most commonly in the distal femur, proximal tibia and fibula and the proximal humerus. There are no large studies focusing on the clinical presentation, management and outcome of treatment for patients with an osteochondroma involving the proximal fibula. The purpose of this study is to specifically understand the manifestation of the proximal fibular osteochondroma on the preoperative peroneal nerve function, and how surgical management of the osteochondroma affects function immediately postoperatively and at long-term followup. This is an IRB-approved retrospective review of a consecutive series of patients with a proximal fibular osteochondroma (PFO) treated operatively at a single institution from 1990 to 2013. The medical record was carefully reviewed to identify demographic data, clinical data and especially the status of the peroneal function at various time points. There were 25 patients with 31 affected extremities who underwent surgical excision of the PFO at an average age of 12.4 years (range 3.0–17.9 years). There were 16 males and 9 females. The underlying diagnosis was isolated PFO in 2(8%) patients and multiple hereditary exostosis (MHE) in 23(92%) patients. Preoperatively, 9 (29%) had a foot drop and 22 (71%) did not. Those with preoperative foot drop underwent surgery at a younger age (9.1 vs 13.8 years) (p<0.004). Five of the nine (55.5%) had complete resolution, three (33.3%) had improvement, and one (11.1%) persisted postoperatively and required AFO. Of the 22 who were normal preoperatively, 5 (22.7%) developed a postoperative foot drop-three (60%) completely resolved, 1 (20%) improved, and 1 (20%) persisted and was found to have a transected nerve at exploration. In total, 23 of the 25 (92%) patients who had a PFO excision, had a normal or near-normal peroneal nerve function including those who had poor function preoperatively. A proximal fibular osteochondroma can result in a high incidence of peroneal nerve dysfunction prior to any treatment, but responds the majority of the time to surgical intervention with removal of the osteochondroma. For those who have normal preoperative function, 1 in 4 will develop a postoperative foot drop but nearly all improve spontaneously unless iatrogenic injured

Abstract. Background. Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. Treatment needs to be customised to the patient taking into consideration injury to the knee; associated neurovascular and systemic injuries. Objective. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Methods. Seventy patients with knee dislocation were treated with multi-ligament reconstruction at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 3 weeks was preferred unless the patient was too unstable (Injury severity score>16). PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score. Results. The mean age of the patients was 35yrs (17–74), 53 males and 17 females. 5 patients had CPN injury (7%), 3 had vascular injury (4.2%), 2 had combined CPN and vascular injury (2.8%). Acute surgical treatment was done in 48 patients while 10 had staged reconstruction. 22 patients had delayed reconstruction. The mean follow-up period was 4.8 years (1–12 yrs). According to the IKDC score 67% of the patients had near-normal knee function. The mean Tegner activity scale postoperatively was 4.5 (preinjury 6.5) and the mean KOOS score was 75.3. Four patients had stiffness and needed arthroscopic arthrolysis, two patients had a residual foot drop from the original injury and needed tendon transfer. Conclusion. Traumatic knee dislocation is a challenging problem but good outcomes can be achieved by surgical management

Introduction. Tomita En-bloc spondylectomy (TES) of L5 is one of the most challenging spinal surgical techniques. A 42-year-old female was referred with low back pain and L5 radiculopathy with background of right shoulder excision of liposarcoma. CT-PET confirmed a solitary L5 oligometastasis. MRI showed thecal sac indentation and therefore was not suitable for stereotactic ablative radiotherapy (SABR) alone. Planning Methodology. First Stage: Carbon fibre pedicle screws were planned from L2 to S2AI-Pelvis, aligned to her patient-specific rods. Custom 3D-printed navigation guides were used to overcome challenging limitations of carbon instruments. Radiofrequency ablation (RFA) of L5 pedicles prior to osteotomy was performed to prevent sarcoma cell seeding. Microscope-assisted thecal sac-tumour separation and L5 nerve root dissection was performed. Novel surgical navigation of the ultrasonic bone cutter assisted inferior L4 and superior S1 endplate osteotomies. Second stage: We performed a vascular-assisted retroperitoneal approach to L4-S1 with protection of the great vessels. Completion of osteotomies at L4 and S1 to en-bloc L5: (L4 inferior endplate, L4/5 disc, L5 body, L5/S1 disc and S1 superior endplate). Anterior reconstruction used an expandable PEEK cage obviating the need for a third posterior stage. Reinforced with a patient-specific carbon plate L4-S1 promontory. Sacrifice of left L5 nerve root undertaken. Results. Patient rehabilitated well and was discharged after 42 days. Patient underwent SABR two months post-operatively. Despite left foot drop, she was walking independently 9 months post-operatively. Conclusion. These challenging cases require a truly multi-disciplinary team approach. We share this technique for a dual stage TES and metal-free construct with post adjuvant SABR for maximum local control

The October 2012 Spine Roundup. 360. looks at: a Japanese questionnaire at work in Iran; curve progression in degenerative lumbar scoliosis; the cause of foot drop; the issue of avoiding the spinal cord at scoliosis surgery; ballistic injuries to the cervical spine; minimally invasive oblique lumbar interbody fusion; readmission rates after spinal surgery; clinical complications and the severely injured cervical spine; and stabilising the thoracolumbar burst fracture

To evaluate the gait of five-year old children with club-feet initially treated non-operatively with the French functional technique and to compare these results to the data from this same cohort at the age of two years. Thirty-three patients (fifty-two idiopathic clubfeet) were initially treated with the French functional (physiotherapy) program. At the age of two years, no child underwent surgery for its clubfoot. Gait Analysis was performed with the VICON system (kinematics). At the age of five years, these patients were all re-evaluated in the gait laboratory. Of the thirty-three patients (fifty-two clubfeet) initially treated non-operatively and tested in the gait lab at two years of age, thirty-seven feet required subsequent surgery by the age of five years. This included posterior release (41%), posteromedial release (35%), tibial osteotomy (19%), and tendo Achilles lengthening (5%). The proportion of feet with the following gait parameters changed significantly (p< 0.05) between the ages of two and five years: Equinus (15% at 2 yrs vs. 2% at 5 yrs), Calcaneus (7% vs. 23%), Foot Drop (18% vs. 4%). The proportion of patients with internal foot progression angle did not change over this time (46% vs. 50%), nor did the proportion with normal sagittal plane ankle motion (61% vs. 54%). At age two years, the majority of patients treated with the French Functional non-operative treatment had normal sagittal plane ankle motion. Gait disturbances, when present at this age, were generally ankle equinus, foot drop and in-toeing. By the age of five years, 71% of these patients underwent surgery for their clubfeet. When re-tested in the gait laboratory at age five years, the proportion of feet with normal sagittal plane ankle motion did not change significantly, however, their resultant gait disturbances, when present, were predominantly calcaneus rather than equinus and foot drop. By treating patients with clubfeet with the French Functional technique exclusively, equinus gait may result in a small proportion. By subsequently treating these patients surgically after the age of two years, over-lengthening or over-release may occur and result in calcaneus gait. The French originators of this technique now incorporate an early gastrocsnemius fascial lengthening as part of their technique. This modification of their technique should improve the gait characteristics observed at two years of age and should decrease the necessity for late surgery that may have contributed to the gait characteristics observed at five years of age

Introduction: Although distraction osteogenesis techniques have been used clinically for the treatment of many skeletal conditions with great success over the last 2 decades, one-step larger extent tibial lengthening (> 5 cm) still remains a clinical challenge. In which tension unbalance of bone and soft-tissue may occur, and complications such as foot drop, ankle and knee dysfunction, cartilage injure and secondary osteoarthritis were common. We have designed and manufactured a new lengthener, which allows bone and soft tissue to be lengthened in synchronism, and ankle joint remain in functional position and may move freely during lengthening. Methods: A dynamic cross joint apparatus at ankle level was added to a classic Ilizarov circular four-ring lengthener, the apparatus is consisted of a half ring, two dynamic junctions and an elastic (spring) device. In application pins were inserted into distant and proximal segment of the tibia, also through calcanues, the external fixator with the trans-joint device was then applied. Total 296 patients (age 6–46, average 21), 466 legs, were treated with this new lengthener, among them were 55 cases of infantile paralysis, 38 cases of post-trauma bone defects, 33 cases with congenital dysplasia and 170 cases of chordrodysplasia, rickets, dwarf and short stature (height < 148cm). Unilateral tibia lengthening was performed in 126 legs and bilateral tibia lengthening was performed in 340 legs. Results: Average lengthening for lower limb discrepancy cases was 6.8 cm (2–8cm), and 8.8 cm (8–18cm) for dwarf and short stature. Patients can stand straight and walk during the lengthening. Average movement of ankle joint remained at 10 degree in all cases and x-ray confirmed that average ankle joint space was 2.2 mm (1–4mm). There was no foot drop and ankle joint deformity seen, and in 98% cases ankle joint function fully recovered within 1.5 years after lengthening (6–8 months). Common complications were pinhole infection (25 cases) and broken pin (8 cases). If total lengthening was over 10cm, 70% cases developed slight ankle joint stiffness that would gradually recover after physiotherapy. Severe complications occurred in 5 cases (1%), including nonunion 1 case, mal-union 1 case, bone deformity 1 case and re-fracture 2 cases. All of those cases were cured with satisfactory clinical outcome. Discussion: The challenge of larger range tibial lengthening is mainly the soft tissue complications, such as foot drop, varus and valgus deformity of ankle joint and loss of ankle function. Prolonged soft tissue traction around the ankle joint may lead to increasing cartilage compression, cartilage damage and partial or permanent loss of joint function. Our dynamic lengthener would allow synchronized lengthening of triceps, Achilles tendon and prosterior tibia muscle with tibia, maintain ankle joint space and free ankle movement. This device was simple and easy to apply, with no need of additional Achilles tendon lengthening. Our clinical study has demonstrated that this device drastically reduced the rate of soft tissue complication. This device makes larger extent tibial lengthening (> 5cm) safer and realistic in clinical practice

Aim. Vascularized fibula flap is one of the available options in the management of bone loss that can follow cases of severe haematogenous osteomyelitis. The aim of this study was to evaluate the outcomes of this procedure in a pediatric population in a Sub-saharan setting. Method. The retrospective study focuses on the procedures done in the period between October 2013 and December 2016. Twenty-eight patients, 18 males and 10 females, were enrolled. The youngest was 2 years old, the oldest 13. The bones involved were tibia (13), femur (7), radius (5) and humerus (3). In 5 cases the fibula was harvested with its proximal epiphysis, whereas in 17 cases the flap was osteocutaneous and osseous in 6 cases. In most cases, operations for eradication of the infection were carried out prior to the graft. The flap was stabilized mainly with external fixators, rarely with Kirschner's wires or mini plate. No graft augmentation was used. Results. Graft integration was achieved in 24 cases. Three cases of early flap failure required the removal, while in one case complete reabsorption of the flap was noted a few months after the procedure. The follow-up period ranged from a minimum of 2 and half to a maximum of 6 years. Integration of the graft was obtained in a period of 4 months on average. The fibular flap with epiphysis had good functional outcomes with reconstruction of articular end. Early and delayed complications were observed. All grafts underwent a process of remarkable remodeling. No major problems were observed in the donor site, except for a transitory foot drop that resolved spontaneously. Conclusions. Reconstruction of segmental bone defects secondary to hematogenous osteomyelitis with vascularized fibula flap is a viable option that salvages and restores limb function. It can be safely used even in early childhood. The fibula can be harvested as required by the local conditions. When harvested with a skin island, bone loss and poor soft tissues envelope may be addressed concurrently. The procedure is long and difficult but rewarding. When surgical skills and facilities are available, it can be carried out even in settings located in low resources countries

Introduction. Severely comminuted, displaced acetabular fractures with articular impaction in the elderly population present significant treatment challenges. To allow early post-operative rehabilitation and limit the sequelae of immobility, treatment with acute total hip replacement (THA) has been advocated in selected patients. Achieving primary stability of the acetabular cup without early migration is challenging and there is no current consensus on the optimum method of acetabular reconstruction. We present clinical results and radiostereometric analysis of trabecular metal (TM) cup cage construct reconstruction in immediate THA without acetabular fracture fixation. Methods. Between 2011 and 2016, twenty-one acetabular fractures underwent acute THA with a TM cup cage construct. Patient, fracture and surgical demographics were collected. They were followed up for a mean of 24months (range 12–42months). Clinical and patient reported outcome measures were collected at regular post-operative intervals. Radiosterometric analysis (RSA) was used to measure superior migration and sagittal rotation of the acetabular component. Results. Thirteen fractures were classified as anterior column posterior hemi-transverse, two anterior column, two transverse and four associated both column acetabular fractures. There was one case of trochanteric fracture and transient foot drop. Mean Harris Hip Scores at 12months was 79 (range 33–98). The mean proximal migration of the acetabular components at 12months was 0.91mm (range 0.09–5.12 and mean sagittal rotation was 0.52mm (range 0.03–7.35). Conclusion. The TM cup-cage technique requires a single approach and provides immediate cup stability allowing full weight bearing day one post-op. To our knowledge this is the first study to accurately measure cup stability following THA for an acetabular fracture. Our promising early clinical and radiological outcomes suggest this technique may be an alternative to a fix and replace construct for immediate THA for acute acetabular fractures in the elderly

Ponseti first advocated his treatment for idiopathic clubfoot in the early 1950's. The method has only gained popularity and widespread use since the 1990's. Despite publications showing favourable results, there is little published data scrutinising the change in modes of talipes treatment. This study sought to define the trends in treatment for Idiopathic Clubfoot in Scotland over a twelve-year period (1997 – 2008). (i) A review was performed to identify the number of publications referencing the Ponseti method over the past 40 years. (ii) A structured questionnaire was sent to all Paediatric Orthopaedic practitioners in Scotland to ascertain the treatment methods used and over the time period. (iii) Data from the National Census for number of live births were combined with that obtained from the Scottish Morbidity Record (SMR01) for number of peritalar clubfoot surgeries performed over the study period. (iv) Similar data was also obtained for non-Talipes related peritalar surgeries, and data colleceted for the number of Tibialis Anterior transfer operations for this period. Clubfoot incidence data was measured indirectly by means of sample from the database of a tertiary referral Paediatric Orthopaedic Unit. Regression analysis was used to evaluate the trends over time. Review of the literature referencing the Ponseti method over the past 40 years showed an exponential increase from the late 1990's. The survey of Clubfoot management of Paediatric Orthopaedic Surgeons in Scotland showed a marked increase in use of the method over with this period. Over this period, the number of operations for clubfoot dropped substantially, from 55 releases in 1997 to 1 release in 2008. The linear equation estimated a decrease of approximately 5 surgical releases per year (R²= 0.87, p<0.05). In Scotland, most Tibialis Anterior transfers are performed at age 3years, the frequency of the procedure has increased in the latter half of the study period. In Scotland between 1997 and 2008, the number of peritalar (posterior, medial, posteromedial release) operations used in the primary treatment of idiopathic clubfoot has dropped substantially. This correlates with a marked increase in reference to the method within the literature and increased usage of the Ponseti technique by Paediatric Orthopaedic Consultants

Introduction. The management of a significant bone defect following excision of a diaphyseal atrophic femoral non-union remains a challenge. Traditional bone transport techniques require prolonged use of an external fixator with associated complications. We present our clinical outcomes using a combined technique of acute femoral shortening, stabilised with a deliberately long retrograde intramedullary nail, accompanied by bifocal osteotomy compression and distraction osteogenesis to restore segment length utilising a temporary monolateral fixator. Method. 9 patients underwent the ‘rail and nail’ technique for the management of femoral non-union. Distraction osteogenesis was commenced on the 6. th. post-operative day. Proximal locking of the nail and removal of the external fixator was performed approximately one month after length had been restored. Full weight bearing and joint rehabilitation was encouraged throughout. Consolidation was defined by the appearance of 3 from 4 cortices of regenerate on radiographs. Results. 7 males and 2 females of adult age underwent treatment between 2009 and 2016. The mean lengthening was 6.6cm (3–10cm). The external fixator was removed at a mean 123 days (57–220), with an external fixation index of 20 days/cm. The regenerate healing index was 28 days/cm. There were no deep infections. Significant complications were seen in 4 patients including knee stiffness, a foot drop, delayed union of the non-union osteotomy (requiring exchange nailing and bone grafting) and revision nailing due to a prominent proximal tip. Conclusion. The combined over-sized intramedullary nail and external fixator enables compression of the femoral osteotomy, alignment of the bone and controlled lengthening. Once the length has been restored, removal of the external fixator and proximal locking of the nail reduces the risk of complications associated with the fixator and stabilises the femur with the maximum working length of the nail. This small retrospective study demonstrates encouraging results for this complex clinical scenario

Total knee arthroplasty in the setting of osseous defects has multiple management options. However, the optimal treatment strategy remains controversial. The purpose of this study is to report the clinical and radiographic results of trabecular metal cones in managing osseous defects in the setting of complex primary and revision total knee arthroplasty. There were 129 consecutive total knee arthroplasty procedures performed utilising trabecular metal cones reviewed for clinical and radiographic outcomes. Twenty-five had less than 2 years of follow-up and seven died, leaving 96 patients for evaluation. This cohort included a total of eighty-six (86) tibias with eleven (11) having Type 1 defects, twenty-five (25) having Type 2A defects, forty-three (43) with Type 2B defects and seven (7) with Type 3 defects. There were twenty-seven (27) femurs with one (1) Type 1 defect, nine (9) Type 2A defects, sixteen (16) with Type 2B defects and one (1) Type 3 defect based on the AORI classification. There were 28 male patients and 68 female patients, with an average age of 68 years and an average BMI of 35.0. There were six primary procedures and ninety revision procedures. Continuous variables were evaluated using a t-test. Twelve patients required revision leaving 84 knees (87.5%) with the cones in place at an average of 31 months of follow-up (range, 24–77.3 months). The mean KSS score increased from 51.0 preoperatively to 80.2 postoperatively (p<0.0001). The mean KSS functional score increased from 32.9 preoperatively to 47.8 postoperatively (p=0.0002). Including the twelve revisions, there were twenty-two knees requiring re-operation (22.9%) with another seventeen requiring manipulation under anesthesia and there were four additional non-operative complications (1 foot drop, 1 stress fracture, 2 superficial infections)

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

Introduction. The incidence of acetabular fractures in the elderly population is increasing. Treatment with staged or acute total hip arthroplasty (THA) is occasionally required. The role of acute THA however, remains controversial. The purpose of our study was to assess the outcomes of a subgroup of elderly patients who underwent early simultaneous open reduction and internal fixation (ORIF) and primary THA for displaced acetabular fractures. Materials and Methods. 86 patients underwent ORIF for displaced acetabular fractures at The Alfred Hospital, Melbourne between August 2007 and August 2009. Eight of these patients underwent early simultaneous ORIF and primary THA. Mean age was 79 years. Mean time between injury and surgery was 4 days. Mean time of follow-up was 19 months. There were 3 both-column fractures, 2 anterior column, 1 posterior wall, 1 transverse with posterior wall and 1 T-shaped. Two patients had an associated neck of femur fracture and two had an impaction fracture of the femoral head. The Harris and Oxford hip scores were used to assess clinical outcome. Radiographs were analysed for component loosening. Results. There was one unrelated post-operative death at 5 months. There was a high rate of post-operative complications. Four patients developed heterotopic ossification, 2 extensive. There was one superficial and one deep infection. One patient has a persistent post-operative foot drop. The Harris hip scores ranged from 45 to 86 with a mean of 68. The Oxford hip scores ranged from 24 to 37 with a mean of 32. There was no evidence of acetabular component loosening. Conclusion. Acute THA for displaced acetabular fractures in the elderly is associated with significant post-operative complications and relatively poor clinical outcomes. However, we believe there may be an indication for this treatment when there is an associated ipsilateral fracture of the femoral neck or femoral head

There are currently no agreed guidelines for the type and frequency of post spinal surgery neurological observations. This lack of an agreed standard can lead to the failure to adequately monitor cord function following surgery and thus neurological deficits can be missed. We have carried out an audit of the postoperative spinal observations against our agreed standards of care. Standards of care:. All patients should have the frequency of required neuro obs documented in the post op instructions. The frequency of documented observations in recovery should be adhered to. The frequency of documented observations in HDU should be adhered to. Any neurological loss should be properly documented. The nurses will report any neurological change promptly. The SHO will exam and document a full neurological examination. 28 case notes were reviewed. 21 of these cases were scoliosis correction through anterior, posterior and combined approaches. 3 had disc replacements, 2 had decompression for metastatic cancer and one had fixa-tion of a fracture. All patients failed to complete all standards fully. There was a lack of clear postoperative guidelines, failure to record neurological status in recovery, incomplete documentation of neurological state in HDU, failure to inform medical staff in presence of a neurological deficit and inadequate assessment of patient by medical staff. One patient returned to theatre for a foot drop, which is still only partially recovered. We recommend the audit of current practice and implementation of locally agreed standards for the postoperative monitoring

Complex primary total knee replacements have been poorly reported in the literature We review all complex primary total knee replacement procedures at Stepping Hill Hospital. Patients underwent knee examination, knee scores, notes review and pre- and post-operative radiograph review. There were 29 patients with 36 knees that had a complex primary total knee replacement. Most frequent indications for surgery were osteoarthritis, rheumatoid arthritis or following trauma. Mean age at surgery 70 years. The prosthesis used were : 3 Stryker Kinemax; 32 De Puy PFC and one rotating hinge. Complex Primary Oxford knee score; preoperative mean 45 (range 33 to 57); postoperative mean 26 (range 14 to 53). NJR Total Knee Replacement Oxford knee score postoperative mean 30. Mean visual analogue scores; pain in the knee, mean 19; knee function, mean 77; outcome of the operation 76; satisfaction with the surgery 87. Mean length of hospital stay 13 days. Using the Knee Society Radiographic Scoring System, there were no signs that need to be monitored or signify failure. Seven patients were transfused postoperatively, four patients had minor wound problems, three required further surgery, two to washout the knee and exchange the polyethylene liner, one femoral plating to stabilise an osteotomy site. Long term complications : one above knee amputation for infection, one foot drop. Revision implants can be used in complex primary knee replacements, and pose technical difficulties but address various pathologies. The surgery is associated with an increased risk of complications and transfusion. Clinical scores at least match scores for routine total knee replacements, patient satisfaction is excellent

Objective. To evaluate the volume of cases, causes of failure, complications in patients with a failed Thompson hemiarthroplasty. Methods. A retrospective review was undertaken between 2005–11, of all Thompson implant revised in the trust. Patients were identified by clinical coding. All case notes were reviewed. Data collection included patients demographic, time to revision, reason for revision, type of revision implant, surgical time and technique, transfusion, complications, HDU stay, mobility pre and post revision,. Results. 23 patients were identified, age 81 years (range 76–90). male to female ratio was 2:21, 11 right and 12 left hip. Mean time to failure was 50 months (1–104 m) range, mean follow up post revision surgery 26 months (3–77). Reason for revision was dislocation in 3 patients (13%), femoral loosening 5 (21%), peri-prosthetic fracture 3 (13%), Infection 6 (26%) and acetabular erosion 6 (26%). There were six infected cases in the study which was all aspirated preoperatively off which only 4 were positive. All infected cases grew an organism from intra-operative specimens. (80% cases) were coagulase negative Staphylococcus aureus. 35% only positive on enrichment cultures. 4 infected Thompsons were revised successfully with 2 stage revisions. One patient died after 1. st. stage and another was able to mobilise after the first stage with a cement spacer and refused further surgery. Mean surgical time was 3.5 hours (range 2.5–5.5). HDU stay 1.3 days (range 0–6). 6 deaths in total, 3 unrelated, 3 post operative. Complications included 1 fracture requiring revision, 1 dislocation, 1 foot drop and 4 chest infection of which two patients died from this. Conclusion. We identified a revision rate of 1.2%, complication occurred in 43% of cases with a one year mortality of 26%. Failed Thompson revision surgery is rare, challenging and patient selection is important to reduce postoperative morbidity and mortality

The purpose of the study was to evaluate the functional outcome of different limb salvage procedures for osteosarcoma about the knee. A selection of patients who have undergone limb salvage procedures for osteosarcoma about the knee were invited to join the study. Medical and operation notes were reviewed along with recent radiographs of the involved limb. Patients completed the Musculoskeletal Tumour Society functional questionnaire and underwent a gait analysis assessing walking and running. Most patients had stage 2B osteosarcoma involving either the proximal tibia or distal femur. Limb salvage procedures included arthrodesis, allograft reconstruction, endoprosthesis and rotationplasty. All patients scored highly (> 70 %) on the MSTS questionnaire except the arthrodesis that scored 57 %. The gait analysis revealed some subtle changes with a quadriceps-sparing gait in the endoprosthesis, mild foot drop in the proximal tibial allograft and a lateral lean of the trunk over the ipsilateral limb in the rotationplasty. The arthrodesis had an obvious straight leg gait with subtle pelvic hiking to assist foot clearance. While analysis of walking was close to normal most patients were unable to obtain a double float and run. This study shows that limb salvage procedures tailored to each individual case can result in an excellent functional outcome with close to normal gait and high MSTS scores

Objective: To analyse the incidence and gravity of reported complications that arise in spinal surgery and assess the comparative safety, or otherwise, of Endoscopic Laser Foraminoplasty. Design: Prospective independently analysed study of complications arising during the six weeks following Endoscopic Laser Foraminoplasty was correlated and compared to a meta-analysis of reported data on complications in conventional spinal surgery. Subjects: Nine hundred and fifty-eight procedures performed on 716 patients. Outcome measures: Occurrence of complications. Results: The cohort integrity of operative and review records at six weeks after surgery was 100%. Twenty four complications occurred in 23 patients: nine cases of discitis (one infective) (0.9%), one dural tear (0.1%), one deep wound infection (0.1%), two patients suffered a foot drop (one transient) (0.2%), one myocardial infarction (0.1%), one erectile dysfunction (0.1%) and one post operative panic attacks (0.1%). MRI later demonstrated eight residual disc herniations (0.8%). The overall surgical complication rate was 1.6%. Meta-analysis of conventional spinal surgery reported overall complication rates for fusion (11.8%), decompression (7.6%), discectomy (6.0%) and chemonucleolysis (9.6%). Conclusions: The complication rate of Endoscopic Laser Foraminoplasty is significantly lower than that reported following conventional spinal surgery (P < 0.01)
