The Femoral Neck System (FNS) was introduced as an alternative device for the fixation of neck of femur fractures (NOFFs). The purported advantages include superior angular and rotatory stability compared to multiple cancellous screws, via a minimally invasive instrumentation that is simpler than conventional fixed angle devices. There were limited clinical studies regarding the utility of this device. We aimed to study the outcomes of NOFFs fixed with the FNS. This was a single-institution, retrospective review of all undisplaced elderly (≥60 years old) undisplaced young, and displaced young NOFFs fixed with the FNS. Demographics, surgical parameters, radiographic parameters, and clinical outcomes including complications were reviewed. Thirty-six subjects with a median age of 75 [44,89] years old, had NOFF fixation using the FNS. Thirty-one (86.1%) had undisplaced fractures. There were 6 (16.7%), 26 (72.2%), and 4 (11.1%) subjects with Pauwels types 1, 2, and 3 respectively. Thirty-two (88.9%) had posterior tilt of <20º. The mean duration of surgery was 71±18 minutes. Excluding 4 patients whom required revision surgery, 2 patients whom demised, and 10 patients whom defaulted reviews, the mean follow-up duration was 55±13 weeks. Four complications were recorded, namely implant cut out at the femoral head at week 8, breaking of the locking screw at the run-off region at week 22, avascular necrosis at week 25, and a refracture following near fall, causing the fracture to fail in varus at week 7 postoperation. While reasonably fast to instrument, failures still occur and it is likely multifactorial. However, the rate of reoperation is lower than what has been reported for NOFFs fixed with the a fixed-angle device or 3 cancellous screws. In conclusion, the FNS is a reasonably safe instrument to use. Surgeons’ discretion is still needed in patient selection, keeping in mind the need for satisfactory radiological parameters

Abstract. Introduction. There is little literature exploring clinical outcomes of secondarily displaced proximal humerus fractures. The aim of this study was to assess the rate of secondary displacement in undisplaced proximal humeral fractures (PHF) and their clinical outcomes. Methods. This was a retrospective cohort study of undisplaced PHFs at Royal Derby Hospital, UK, between January 2018-December 2019. Radiographs were reviewed for displacement and classified according to Neer's classification. Displacement was defined as translation of fracture fragments by greater than 1cm or 20° of angulation. Patients with pathological, periprosthetic, bilateral, fracture dislocations and head-split fractures were excluded along with those without adequate radiological follow-up. Results. In total, 681 patients were treated with PHFs within the study period and out of those 155 were excluded as above. There were 385 undisplaced PHFs with mean age 70 years (range, 21–97years) and female to male ratio of 3.3:1. There were 88 isolated greater tuberosity fractures, 182 comminuted PHFs and 115 surgical neck fractures. Secondary displacement occurred in 33 patients (8.6%). Mean time to displacement was 14.8 days (range, 5–45days) with surgical intervention required in only 5 patients. In those managed nonoperatively, three had malunion and one had nonunion. No significant differences were noted in ROM between undisplaced and secondarily displaced PHFs. Conclusion. Undisplaced fractures are the most common type of PHF. Rate of secondary displacement is low at 8.6% and can occur up to 7 weeks after injury. Displacement can lead to surgery, but those managed conservatively maintain their ROM at final follow up

The aim of this study is to analyse the radiological outcomes and predictors of avascular necrosis following 2-hole DHS in Garden I and II neck of femur fractures in patients more than 60 years with a minimum follow up of one year. We retrospectively reviewed 51 consecutive patients aged more than 60 years who underwent DHS fixation for Garden I and II fractures. Demographics, fracture classification, time to surgery, pre-operative AMTS, preoperative posterior tilt angle, quality of reduction, pre and post-operative haemoglobin(hb), creatinine and comorbidities were analysed for correlation with AVN using Chi-Square test, Independent Sample and paired t test. There were 40 (78.4%) females and the mean age of the cohort was 77 years. 28 and 23 were Garden I and II NOF fractures respectively. Union was observed in all our patients except one(kappa =1). 12/51(23.5%) developed AVN of the femoral head. Statistically significant higher incidence of AVN was noted in patients with a pre-op tilt angle > 200 (p = 0.006). The mean drop in Hb was higher in patients who developed AVN (21.5 g/L) versus the non-AVN group (15.9 g/L) (p = 0.001). There was no difference in AVN rates with respect to laterality, mean time to surgery, pre-op AMTS and Charlson comorbidity index. 4/52 (7.6%) had re-operations (one hardware prominence, two conversions to arthroplasty, one fixation failure during the immediate post-op period). The 30-day and one year mortality rates were 1.9 % and 11.7 % respectively. 2-hole DHS fixation in undisplaced NOF fractures has excellent union rates. A pre-operative posterior tilt angle of >200 and a greater difference in pre and post operative haemoglobin were found to correlate positively with the progression to AVN . No correlation was observed between AVN and time to surgery, laterality, quality of reduction and comorbidities

The treatment of undisplaced femoral neck fracture in the elderly population is still controversial. We analysed the outcome of cancellous screw fixation for undisplaced femoral neck fracture in patients over 70 years. Materials and methods. From 1998 to 2003, ninety-seven patients with undisplaced femoral neck fracture, aged over 70 and treated with cancellous screw fixation were retrospectively identified. Full clinical data was available for 79 of the 97 patients identified. All patients had in situ fracture fixation. Results. Of the 79 patients, M:F was 22:57, average age was 81.3 years. The average inpatient stay was 13.2 days. The mean follow-up was 12 months. 24 patients had Garden type I and 55 type II fractures. 26 (32.9%) patients did not return to their pre-morbid mobility status, 5 (6.3%) did not return to their preadmission dwelling (2 went to residential homes and 3 to nursing homes). We had documented radiographic details in 46 patients: 41 patients had a healed fracture on radiographs (89.1%), 5 patients had AVN, 4 patients had non-union and 1 patient had AVN with non-union. The radiographic failure rate was 22%. 15 patients had evidence of screw back out with healed fracture. 12 of the 46 complained of pain post-operatively of which 9 (19.6%) patients had re-operation; 6 (13%) underwent revision surgery and 3 (6.5%) required screw removal. 30-day mortality was 3.7%. 1-year mortality was 23.2% of which 16 died within the first 6 months (19.5%). Conclusion. This study shows that, in our unit, cancellous screw fixation of undisplaced femoral neck fractures in patients over the age 70 had a good outcome with a 20% re-operation rate and 22% radiographic failure rate. One third of the patients did not return to their preadmission mobility level/dwelling

Background. Current literature of definition, classification and outcomes of fractures of talar body remains controversial. Our primary purpose is to present an unusual combination of fractures of talar body with pantalar involvement / dislocation / extension as a basis for modification of Müller AO / OTA Classification. Methods. We include four consecutive patients, who sustained talar body fractures with pantalar subluxation/dislocation /extension. These unusual injury patterns lead us to reconsider Müller AO / OTA Classification in the light of another widely used talar fracture classification, Hawkins Classification of fractures of neck of talus and subsequent modification by Canale and Kelly. Results. Müller AO / OTA Classification comprises CI – Ankle joint involvement, C2 – Subtalar joint involvement, C3 – Ankle and subtalar joint involvement. We propose Modification of Müller AO / OTA. Classification. C1 – Absolutely undisplaced fracture; C2 – Ankle and Subtalar joint involvement: subluxation; C3 – Ankle and subtalar joint involvement: subluxation with comminution; C4 – Ankle, subtalar and talonavicular joint involvement. Conclusions. Our modification redefines Müller AO / OTA Classification, extends and fills the void in the classification by inclusion of C4, draws attention to stability of talonavicular joint and reflects increasing severity of injury in fractures of talar body

The aim of this retrospective study was to evaluate the failure rate among different fixation devices for undisplaced fracture neck of femur. All 52 patients with Garden I and II hip fractures who underwent surgery in a teaching hospital in London from January 2007 to June 2012 were included. Electronic patient records were accessed to collect the patient data. There were 52% females and the mean age of patients was 70 years. Thirty patients had cannulated screws, 18 – dynamic hip screw (DHS) with de-rotation screw and 4 had DHS alone. Initial results showed that 36% patients had re-operation. 7(77%) had total hip replacement and 1(11%) had metal work removal. The reason for revision was failure of fixation in 8 (88%) and avascular necrosis in 1 (11%). There was significantly higher failure rate in the DHS with derotation screw group (50%) compared to the cannulated screw group (35%) and the DHS alone group (0%). Average time to planned revision was 11.1 months. Traditionally undisplaced intra capsular hip fractures are treated by in-situ fixation using different devices. Biomechanically DHS with de-rotation screw achieves better rotational and axial stability compared to other fixation devices. However, our study showed a higher failure rate in this group. Inability to achieve a perfectly parallel screw position seems to be a significant factor responsible for high failure. Higher failure rates with fixation may boost the role of replacement arthroplasty as one off surgical treatment in elderly patients

As the incidence of total hip arthroplasty (THA) rises, an increasing prevalence of peri-prosthetic femur fractures has been reported. This is likely due to the growing population with arthroplasties, increasing patient survival and a more active life-style following arthroplasty. It is the 3rd most common reason for THA reoperation (9.5%) and 5th most common reason for revision (5% with fracture risk after primary THA reported at 0.4%-1.1% and after revision at 2.1%-4%). High quality radiographs are usually sufficient to classify the fracture and plan treatment. Important issues in treatment include stem fixation status and fracture location relative to the stem. Additional comorbidities will also influence treatment choices, of which the most critical is the presence of infection and the quality of bone stock. The most commonly studied, and reported classification system is the Vancouver. Type A are peri-trochanteric fractures with AL at the lesser and AG at the greater trochanter. B fractures are those around the stem with B1 fractures having a well-fixed stem, B2 a loose stem with adequate bone stock, and B3 representing loose stem and inadequate bone stock. C fractures are distal to the stem. Type A) Trochanteric Fractures: These are usually associated with lysis. Displaced fractures can be managed adequately with cerclage fixation and cancellous allograft to fill osteolytic defects. Undisplaced fractures usually heal well with symptomatic treatment. Type B) Fractures Around the Stem: The B1 type has a well-fixed component and is usually treated with extramedullary fixation plus graft. Contemporary plates have been designed specifically for these fractures. Strut allograft may be used to provide a more rigid construct. Spiral and long oblique fractures can be cerclaged while short oblique or transverse fractures require fixation anterior and lateral with cable plates and cortical strut grafts. Screws can be used distal to the implant, and cables used proximally. The B2 type has a loose prosthesis but otherwise good bone stock. In this setting, the fracture line may be extended on the lateral cortex of the femur as an extended osteotomy to provide easy access for cement removal. These fractures can be managed with an extensively coated stem if rotational stability can be obtained in the distal segment. If rotational stability over a 4 cm scratch interference fit of the stem isn't possible, then a fluted tapered modular stem should be used. Strut allografts improve initial stability. The B3 type has both a loose prosthesis and poor bone stock and in the younger patient restoration of bone stock should be a priority. Bulk femoral grafts may be needed. The elderly or low functional demand patient may be treated with a proximal femoral replacement. Because of soft-tissue deficiencies, a constrained acetabular liner may be needed to prevent instability. Type C) Fractures Distal to the Stem: These usually accompany a stable stem and many fixation devices are available. Locking plates have become most popular and should be secured with cerclage wires proximally around the component with screws distally. Retrograde nails may be employed if there is adequate bone distal to the stem tip and above the fracture

The most important determinant in the treatment of malleolar fractures is stability. Stable fractures have an intact deep deltoid ligament and do not displace with functional treatment. If the deep deltoid/medial malleolar complex is disrupted, the talus is at risk of displacement. Weber (2010) showed that weightbearing radiographs predicted stability in patients with undisplaced ankle fractures. We developed clinical criteria for potential instability and applied them to a prospective series of patients. Criteria included: medial clear space of < 4mm; medial tenderness, bruising or swelling; a fibular fracture above the syndesmosis; a bimalleolar or trimalleolar fracture; an open fracture; a high-energy fracture mechanism. A consecutive, prospectively documented series of 37 patients chose functional brace treatment of potentially unstable fractures. Weightbearing radiographs were performed in the brace before treatment, and free of brace at clinical union (6–9 weeks in all patients). Patients were encouraged to bear full weight and actively exercise their ankles in the brace. All fractures healed without displacement. The risk of displacement was 0% (95% CI 0–11.2%). This preliminary series gives support for the use of weightbearing radiographs to guide treatment of undisplaced ankle fractures

Introduction. Varus malpositioning of femoral stems has been recognised as a poor prognostic feature with regard to loosening and failure of cemented composite beam implants, but there have been no published results of the long-term effect on taper-slip designs. Objectives. To determine the results of varus placement of a polished triple tapered femoral stem. Methods. We have prospectively analysed the results of 350 consecutive polished triple-tapered C-Stem implants performed on 322 patients between March 2000 and July 2004, using a standard posterior approach and Palacos-R cement. All patients underwent annual clinical and radiological review. Results. The average duration of follow-up in surviving patients is 140 months (120–172 months). There were 49 femoral implants in 49 patients implanted with more than 5 degrees of varus (14%) with respect to the long axis of the femur, and 14 in 14 patients in more than 5 degrees of valgus (4%). Alignment within 5 degrees of neutral was achieved in 82% of cases. The average age in the varus group was 69.2 years (41–92), which was higher than in the neutral group (67.4 years: 25–89), more patients were male (49% v 36%) but the average BMI was similar (29 v 28). The average duration of follow-up was the same. There was only one re-operation in the varus group, which was a revision for deep infection. There was one dislocation successfully treated by closed reduction and one acetabular component is currently loose. In the neutral group there have been four dislocations, one of which required application of a PLAD; five revisions for aseptic loosening of the acetabular component associated with high wear rates, with a further three currently being loose; four intra-operative, undisplaced fractures of the greater trochanter; two peri-prosthetic femoral shaft fractures treated by internal fixation and two temporary nerve palsies. There has been no aseptic loosening of the femoral components in either group. Subsidence of the femoral stem within the cement mantle was noted in 96% of the entire series. There was no significant difference between the groups with respect to the degree of subsidence. In the varus group 78% subsided less than 2mm compared to 75% in the neutral group. None of the femoral implants in either group subsided more than 4mm and none demonstrated evidence of aseptic loosening or negative bone remodelling. Conclusion. Varus implantation of the femoral component was more common in older, male patients, but there was no increased risk of subsidence or loosening at a minimum follow-up of ten years

1133 patients with an intracapsular fracture of femoral neck treated by internal fixation were prospectively studied. All surviving patients were followed up for a minimum of one year from injury. The overall incidence of non-union was 229 (20.2%) and the incidence of avascular necrosis was 61 (5.4%). Fracture non-union was less common for undisplaced fracture in comparison to displaced fractures (48 out of 565 (8.5%) versus 181 out of 568 (31.9%)) and in males than females (45 out of 271 (16.6%) versus 184 out of 862 (21.3%)). The incidence of non-union progressively increased with age from one out of 17 (5.9%) in those aged below 40 years to 84 out of 337 (24.9%) in those in their seventies. For those in their eighties the incidence of non-union began to fall, but if those patients who died within one year from injury were excluded, then the incidence was found to continue to increase. For avascular necrosis there was a falling incidence with age from 9 out of 68 (13.2%) in those aged less than 50 years to 10 out of 388 (2.6%) in those aged over 80 years. The information from this large series of patients treated by contemporary methods enables the surgeon to use the three factors of age, sex and presence of fracture displacement to predict the risk of non-union or avascular necrosis occurring

Management of periprosthetic femoral fractures above a Total Knee Arthroplasty remains a challenge. The different treatment options available include casting for undisplaced fractures, ORIF for a displaced fracture with a well-fixed implant or revision arthroplasty for a very distal fracture and for a fracture with a loose implant. We describe our experience in treating a very distal displaced supracondylar fracture above a well-fixed femoral component in a 68-year-old woman who was recently diagnosed with breast carcinoma and awaiting mastectomy. There was no evidence of metastatic disease. The knee replacement was done 4 years before and the patient did not have any symptoms in the knee prior to the fall. Conventional ORIF with IM nailing or plate osteosynthesis was not possible due to the very distal site of the fracture. We used a custom modified 95 degree angled blade plate in which a slot was cut in the middle of the blade halfway along its length to accommodate the pegs of the femoral component in the distal fragment. The fracture was reduced and fixed with the angled blade plate restoring length, alignment, and providing coronal stability. The patient had a satisfactory union at 3 months without deformity giving a good range of pain free movement in the knee. DCS and 95 degree angled blade plate have been used in the past with mixed results. The lag screw or the blade has to be inserted more proximally to avoid the femoral component and so the distal fixation is often sub optimal. In our case modification of the blade allowed more distal placement providing optimal fixation and avoiding complex revision surgery

Michael Robinson has been a Consultant Orthopaedic Surgeon and Senior Lecturer in the Department of Orthopaedics and Traumatology in Edinburgh, Scotland, United Kingdom for 10 years. His special interests include the treatment of proximal humeral and clavicle fractures, and shoulder instability. The traditional view that the vast majority clavicle fractures heal with non- operative treatment with consistently good functional outcomes is no longer valid. Recent studies have identified a higher rate of nonunion and specific defects of shoulder function in sub-groups of patients with these injuries. These fractures should therefore be viewed as a spectrum of injuries with diverse functional outcomes, each requiring careful assessment and individualised treatment. This talk provides an overview of the current knowledge regarding their epidemiology, classification, clinical assessment and treatment in adults. The following key points will be highlighted:. Undisplaced fractures of both the diaphysis and the lateral end of the clavicle have a high rate of union and good functional outcomes after non-operative treatment. Non-operative treatment of displaced shaft fractures may be associated with a higher rate of non-union and functional deficit than previously reported. However, it remains difficult to predict which patients will develop these complications. Since satisfactory functional outcome may be regained from operative treatment for clavicular nonunion or malunion, there is currently considerable debate about the benefits of primary operative treatment for these injuries. Displaced lateral-end fractures have a higher risk of nonunion after non-operative treatment than shaft fractures. However, nonunion is difficult to predict and may be asymptomatic in the elderly. The results of operative treatment are more unpredictable than for shaft fractures. None of the authors have received any payment or consideration from any source for the conduct of this study

Prevalence of rotator cuff tears increases with advancing age (Ellman et al). In spite of proximal humeral fractures being common in the elderly, the influence of a coexistent rotator cuff tear on outcome has, to our knowledge, not been previously investigated. This study prospectively assessed whether the presence of a rotator cuff tear in association with a proximal humeral fracture influences functional prognosis. 85 patients treated conservatively for proximal humeral fractures were evaluated prospectively with Ultrasonography to determine the status of the rotator cuff. Every patient was managed by immobilisation of the arm in a sling for two weeks followed by a course of physiotherapy based on the Neer regime. Functional outcome was measured using the Constant shoulder score and the Oxford shoulder score, at 3-months and 12-months post injury. Sixty-six of the 85 patients were female. The fractures were equally distributed for hand dominance. There were 27 patients with an undisplaced fracture, 34 patients with Neer's Type II fracture and 24 patients with Neer's Type III and IV fracture. There were 43 patients with full thickness cuff tears and 42 patients with no cuff tear or a partial thickness tear. Full thickness cuff tears were much more frequent in the over 60 year age group, which is consistent with the known increased incidence of cuff tears with increasing age. The outcome scores at 3 and 12 months showed no statistically significant difference for either the Constant score or the Oxford score with regards to cuff integrity. Analysis of these scores showed no correlation between presence or absence of a full thickness cuff tear and shoulder function. The results of this study indicate that rotator cuff integrity is not a predictor of shoulder function at 12 months following proximal humeral fracture, as measured by outcome scores. This suggests that there is therefore no clinical indication for routine imaging of the rotator cuff in patients for whom conservative management is the preferred treatment option

We have identified 69 patients with Vancouver B1 periprosthetic fractures around stable femoral implants. Open reduction internal fixation is the recommended treatment; however recent studies have revealed high rates of nonunion. We have reviewed the fixation techniques utilized to treat these patients, and identified outcomes in relation to rates of union, further surgery and mortality. Patients were identified from a prospective database of all trauma admissions at Nottingham University Hospitals from 1999 to 2010. Hospital notes were independently reviewed and data retrieved. 69 patients were identified. Mean age 77 years and 63% were female. 51 (74%) occurred around total hip replacements and 18 (26%) around hip hemiarthroplasty after a previous hip fracture. Periprosthetic fracture occurred around an Exeter stem (n=18), Charnley (n=10), Austin Moore (n=15), other (n=6). 20 patients had undergone previous revision surgery. The mean time from index surgery to fracture was 58 months (median 24) around primary stems, and 48 months (median 22) around revision stems. 6 patients (9%) were treated non-operatively. Five of these had undisplaced fractures (all healed but one required revision due to loosening) and one was too unwell. 63 patients (91%) were treated by open reduction internal fixation. Of these, single plate fixation was performed in 40 cases (64%). In the vast majority of cases, lag screw fixation of the fracture with a long (>12 hole) pre-contoured 4.5mm locking plate was utilised with cables. Both locking and cortical screws were used to achieve stable fixation (Figure 1). A double plate technique was used in 16 cases (25%), where plates were placed perpendicularly to each other (laterally and anteriorly). Strut grafts were used in 13 cases (21%). 7 patients (11%) were treated with cables alone. 23 patients have subsequently died (33%). Two have been lost to follow up and three are awaiting union. There is a mean follow-up of 35 months. Deep infection occurred in 4 cases (6%). Non-union occurred in four cases (6%). Two of these were infected and one was treated with cables alone. Malunion occurred in one case treated with cables. One patient had a dislocation and two superficial infections occurred. Further surgery took place in 8 patients (12%). Three of the infected cases were revised and one underwent wound washout. The two other non-unions were revised. Three further revisions were performed: one for malunion, one for aseptic loosening (treated non-operatively) and another for a second periprosthetic fracture. Superficial wound washout was performed in one case. Mortality was 10% at 3 months, 22% at 1 year and 47% at 3 years. We have identified that union can be achieved in the majority of cases after periprosthetic fracture fixation. Cable fixation was associated with a high complication rate (7 cases: two requiring revision surgery: one nonunion, one malunion). We recommend that Vancouver B1 periprosthetic fractures are treated with meticulous technique to achieve anatomical reduction and fracture compression using lag screw technique and plating. Further mechanical support can be provided through the use of a second plate, cables and/or strut grafts

There is ongoing debate regarding the optimal management of displaced distal radius fractures in the elderly. The aim of this review was to compare outcomes of operatively versus non-operatively managed displaced extra-articular or undisplaced intra-articular distal radius fractures in patients 65 years and older. All patients over the age of 65 years with displaced extra-articular or undisplaced intra-articular fractures seen in Tauranga Hospital between 1. st. January 2009 and 31st December 2009 were included in the study. Patients from out of town, with incomplete radiographs or who had since passed away were excluded as were patients with comminuted intra-articular or undisplaced/minimally displaced extra-articular fractures. Patients attended follow-up where clinical assessment was carried out by a single Hand Therapist who was blinded to the side of injury and previous management, completed the Patient Rated Wrist Evaluation (PRWE) and DASH questionnaires and a visual analogue satisfaction score. There were 91 distal radius fractures in patients 65 years and older seen in Tauranga Hospital over this 1 year period. 44 were excluded leaving 47 patients. 6 declined follow-up and 5 failed to attend. 36 patients (3 males, 33 females, average age 74.7 years) were included in the study – 23 had been treated non-operatively with casting +/− manipulation while the remaining 13 patients had undergone open reduction and internal fixation. Comparing the injured with the uninjured wrist in the operatively managed group there was an average loss of 5.8 degrees flexion, 1.2 degrees extension, 1.7 degrees ulnar deviation and 3.8 degrees supination with a gain of 0.7 degrees radial deviation, no change in pronation and a loss of 1.2kg in grip strength. These operatively managed patients had an average PRWE score of 6.5, DASH score of 31.5 and satisfaction score of 8.8. Conversely, in the non-operatively managed group there was an average loss of 17.5 degrees flexion, 9.4 degrees extension, 11.3 degrees ulnar deviation and 10.9 degrees supination with a gain of 0.1 degrees radial deviation, no change in pronation and a loss of 4.7kg in grip strength. These non-operatively managed patients had higher PRWE (42.5) and DASH (56) scores and were in general less pleased with their outcomes (mean satisfaction score – 5.6). Patients in the operatively managed group at 12–24 months post-injury had less significant loss of function as well as lower PRWE and DASH scores and higher satisfaction outcome scores

Aims

Chronic osteomyelitis may recur if dead space management, after excision of infected bone, is inadequate. This study describes the results of a strategy for the management of deep bone infection and evaluates a new antibiotic-loaded biocomposite in the eradication of infection from bone defects.
