Periprosthetic femoral fractures are increasing in incidence, and typically occur in frail elderly patients. They are similar to pathological fractures in many ways. The aims of treatment are the same, including 'getting it right first time' with a single operation, which allows immediate unrestricted weightbearing, with a low risk of complications, and one that avoids the creation of stress risers locally that may predispose to further peri-implant fracture. The surgical approach to these fractures, the associated soft-tissue handling, and exposure of the fracture are key elements in minimizing the high rate of complications. This annotation describes the approaches to the femur that can be used to facilitate the surgical management of peri- and interprosthetic fractures of the femur at all levels using either modern methods of fixation or revision arthroplasty.

The purpose of this study is to determine the re-operation rate following plate fixation of the olecranon with contoured anatomic plates. Plate fixation of the olecranon allows for management of different fracture patterns as well as osteotomies with anatomic reduction and stable fixation for early elbow mobilization. However, olecranon hardware prominence can be troublesome. Our hypothesis was with the newer generation of low profile contoured anatomic plates, the rate of hardware removal should be lower compared to previously described literature. Retrospective review for patients treated with operative fixation of the olecranon between 2010 and 2015 in the Edmonton zone was identified using population level administrative data. Radiographic screening of these patients was then carried out to identify those who received plate fixation. Fracture patterns were also characterized. Chart reviews followed to determine the indications for re-operation and other post-operative complications. Main outcome measures were re-operation rate and their indications, including hardware prominence. During the screening process, 600 surgically treated olecranon patients were identified and 321 patients were found to have plate fixation of the olecranon. Chart review determined 90 patients had re-operations demonstrating a 28% re-operation rate. Re-operation due to hardware prominence was found to be 15.6%. Other indications included hardware failure (5.3%), infection (2.8%), or contracture (2.8%). Compared to patients that did not require re-operation, the re-operation group had a higher incidence of Type III olecranon fractures (17.4% vs 8.4%, p = 0.036) and Monteggia pattern injuries (13.5% vs 4.9%, p = 0.008). Recent heteregenous data suggests the hardware removal rate related to implant prominence is between 17–54%. Compared to the literature, this study demonstrated a lower rate at 15.6% with contoured anatomic plating. Also, those with more complex fracture patterns were more likely to require re-operation

Aims. The aim of this study was to compare the functional and radiological outcomes and the complication rate after nail and plate fixation of unstable fractures of the ankle in elderly patients. Methods. In this multicentre study, 120 patients aged ≥ 60 years with an acute unstable AO/OTA type 44-B fracture of the ankle were randomized to fixation with either a nail or a plate and followed for 24 months after surgery. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score. Secondary outcome measures were the Manchester-Oxford Foot Questionnaire, the Olerud and Molander Ankle score, the EuroQol five-dimension questionnaire, a visual analogue score for pain, complications, the quality of reduction of the fracture, nonunion, and the development of osteoarthritis. Results. At 24 months, the median AOFAS score was equivalent in the two groups (nail 90 (interquartile range (IQR) 82 to 100), plate 95 (IQR 87 to 100), p = 0.478). There were statistically more complications and secondary operations after nail than plate fixation (p = 0.024 and p = 0.028, respectively). There were no other significant differences in the outcomes between the two groups. Conclusion. The functional outcome after nail and plate fixation was equivalent; however, the complication rate and number of secondary operations was significantly higher after nail fixation. These results suggest that plate fixation should usually be the treatment of choice for unstable ankle fractures in the elderly. Cite this article: Bone Joint J 2023;105-B(1):72–81

Aims. It is unclear whether acute plate fixation facilitates earlier return of normal shoulder function following a displaced mid-shaft clavicular fracture compared with nonoperative management when union occurs. The primary aim of this study was to establish whether acute plate fixation was associated with a greater return of normal shoulder function when compared with nonoperative management in patients who unite their fractures. The secondary aim was to investigate whether there were identifiable predictors associated with return of normal shoulder function in patients who achieve union with nonoperative management. Methods. Patient data from a randomized controlled trial were used to compare acute plate fixation with nonoperative management of united fractures. Return of shoulder function was based on the age- and sex-matched Disabilities of the Arm, Shoulder and Hand (DASH) scores for the cohort. Independent predictors of an early recovery of normal shoulder function were investigated using a separate prospective series of consecutive nonoperative displaced mid-shaft clavicular fractures recruited over a two-year period (aged ≥ 16 years). Patient demographics and functional recovery were assessed over the six months post-injury using a standardized protocol. Results. Data from the randomized controlled trial consisted of 86 patients who underwent operative fixation compared with 76 patients that united with nonoperative treatment. The recovery of normal shoulder function, as defined by a DASH score within the predicted 95% confidence interval for each respective patient, was similar between each group at six weeks (operative 26.7% vs nonoperative 25.0%, p = 0.800), three months (52.3% vs 44.2%, p = 0.768), and six months post-injury (86.0% vs 90.8%, p = 0.349). The mean DASH score and return to work were also comparable at each timepoint. In the prospective cohort, 86.5% (n = 173/200) achieved union by six months post-injury (follow-up rate 88.5%, n = 200/226). Regression analysis found that no specific patient, injury, or fracture predictor was associated with an early return of function at six or 12 weeks. Conclusion. Return of normal shoulder function was comparable between acute plate fixation and nonoperative management when union was achieved. One in two patients will have recovery of normal shoulder function at three months, increasing to nine out of ten patients at six months following injury when union occurs, irrespective of initial treatment.

Aims. This is a prospective randomised controlled trial comparing the functional outcomes of plate fixation and elastic stable intramedullary nailing (ESIN) of completely displaced mid-shaft fractures of the clavicle in the active adult population. Patients and Methods. We prospectively recruited 123 patients and randomised them to either plate fixation or ESIN. Patients completed the Quick Disabilities of the Arm, Shoulder and Hand (DASH) score at one to six weeks post-operatively. They were followed up at six weeks, three and six months and one year with radiographs, and their clinical outcome was assessed using both the DASH and the Constant Score. Results. Plate fixation provided a faster functional recovery during the first six months compared with ESIN, but there was no difference after one year. The duration of surgery was shorter for ESIN (mean 53.4 minutes, 22 to 120) than for plate fixation (mean 69.7 minutes, 35 to 106, p < 0.001). The recovery after ESIN was slower with increasing fracture comminution and with open reduction (p < 0.05). Conclusion. Both methods return the patients to their pre-injury functional levels, but plate fixation has a faster recovery period in comminuted fractures than ESIN. ESIN has a shorter operative time and lower infection and implant rates of failure when using 2.5 mm nails or wider, suggesting that this is the preferred method in mid-shaft fractures with no comminution, whereas plate fixation is the superior method in comminuted fractures.

Introduction: Weber B fractures are one of the most common fractures of the ankle. Unstable fractures are treated with lateral plating and a lag screw. Another method of fixation is antiglide plating, this concept was first introduced by Brunner and Weber in 1982. Manoli and Schaeffer in 1987, showed that fixation by antiglide plate demonstrated superior static biomechanical properties compared to lateral plating. However there are some shortcomings in their study and hence we decided to perform our biomechanical study. The shortcomings of the Manoli study are. They did not use an interfragmentary lag screw for lateral plate fixation. It was a cadaveric study where the bone does not accurately represent the live bone. The quality of the bone ranging from normal to osteoporotic bone varies from cadaver to cadaver and hence there is no uniformity between the samples. Materials and Methods: We used 4th generation composite bone models validated to closely simulate human bone characteristics for fracture toughness, tensile strength, compressive strength, fatigue crack resistance and implant subsidence. 4th generation composite bone model provides uniformity of test samples which is not achievable in cadaveric studies. These bones were custom made for the experiment. We used two sets of bones, one representative of normal bone (Set A n=10) and the other of osteoporotic bone quality (Set B n=10). Each of the sets A & B will have two types of fixations for artificially created Weber B Fractures. Lateral plate with interfragmentary lag screw. Antiglide plate with interfragmentary lag screw. The strength of the fixation was measured by restressing the bone until the fixation failed using an Instron machine which simultaneously applied torque and compressive forces to the fibular construct. The resulting data was analysed on a computer and statistical analysis was performed. Results: When the two fixation constructs were stressed to failure, the lateral plate construct demonstrated less stiffness (3–5Nm/degree) and failed at lower energy levels (250Nm). Similar values obtained for the antiglide system were, stiffness of 12–16Nm/degree and energy absorbed to failure 350–450Nm. Antiglide plating was significantly more stable in the osteoporotic fibula. Conclusion: Antiglide plating with lag screw is much more stable than lateral plating. It is suitable for treatment without plaster cast post operatively. It results in a more stable fixation in osteoporotic bone

The choice of whether to perform antegrade intramedullary nailing (IMN) or plate fixation (PF) poses a conundrum for the surgeon who must strike the balance between anatomical restoration while reducing elbow and shoulder functional impairment. Most humeral middle third shaft fractures are amenable to conservative management given the considerable acceptable deformity and anatomical compensation by patients. This study is concerned with the patient reported outcomes regarding shoulder and elbow function for IMN and PF respectively. A prospective cohort study following up all the cases treated surgically for middle third humeral fractures from 2016 to 2022 at a single centre. Telephonically an analogue pain score, an American Shoulder and Elbow Society (ASES) score for shoulder function and the Oxford Elbow score (OES) for elbow function were obtained. One hundred and three patients met the inclusion criteria. Twenty four patients participated in the study, fifteen had IMN (62.5%) and nine had PF (37.5%.). The shoulder function outcomes showed no statistical difference with an average ASES score of sixty-six for the IMN group and sixty-nine for the PF group. Women and employed individuals expressed greater functional impairment. Hand dominance has no impact on the scores of elbow and shoulder function post operatively. The impairment of abduction score post antegrade nailing was higher in the antegrade nailing group than the plated group. The OES demonstrated greater variance in elbow function in the PF group with the IMN group expressing greater elbow disfunction. This study confirms that treatment of middle third humerus shaft fractures by plate fixation is marginally superior to antegrade intramedullary nailing in preserving elbow function and abduction ability

Aims. Fixation of scaphoid nonunion with a volar locking plate and cancellous bone grafting has been shown to be a successful technique in small series. Few mid- or long-term follow-up studies have been reported. The aim of this study was to report the mid-term radiological and functional outcome of plate fixation for scaphoid nonunion. Methods. Patients with a scaphoid nonunion were prospectively enrolled and treated with open reduction using a volar approach, debridement of the nonunion, and fixation using a locking plate and cancellous bone grafting, from the ipsilateral iliac crest. Follow-up included examination, functional assessment using the patient-rated wrist/hand evaluation (PRWHE), and multiplanar reformation CT scans at three-month intervals until union was confirmed. Results. A total of 49 patients with a mean age of 31 years (16 to 74) and a mean duration of nonunion of 3.6 years (0.4 to 16) were included. Postoperatively, the nonunion healed in 47 patients (96%) as shown on CT scans. The mean time to union was 4.2 months (3 to 12). Due to impingement of the plate on the volar rim of the radius and functional limitation, the hardware was removed in 18 patients. At a median follow-up of 38 months in 34 patients, the mean active range of motion (ROM) improved significantly from 89° to 124° (SD 44°; p = 0.003). The mean grip strength improved significantly from 52% to 79% (SD 28%; p < 0.001) of the contralateral side. The mean PRWHE score improved significantly from 66 to 17 points (SD 25; p < 0.001). Conclusion. Locking plate fixation supplemented with autologous cancellous bone grafting is a successful form of treatment for scaphoid nonunion. Functional outcomes improve with the passage of time, and mid-term results are excellent with a significant improvement in ROM, grip strength, and functional outcome as measured by the PRWHE.

Background. Plate fixation is one of several options available to surgeons for the management of pediatric femur fractures. Recent literature reports distal femoral valgus can be a complication following lateral plate fixation of femur fractures. We report on a case of extreme distal femoral valgus deformity and a lateral dislocation of the patella four years after having plate fixation of a left distal femoral fracture. Method. A single case was anonymised and retrospectively reviewed through examination of clinical and radiographic data. Results. A 15 year old male presented with 35 degree femoral valgus deformity, one inch leg length discrepancy, painful retained hardware and a lateral dislocation of the patella four years after undergoing lateral plate fixation of a left distal femur fracture. The fracture site healed after plate insertion, but later the patient reported worsening in alignment of lower extremity and complained of pain in the limb. Antero-posterior and lateral radiographs of the femur revealed 35 degrees of left distal femoral valgus. The previous femoral plate migrated proximally and was encased in bone. Due to plate migration, screws that were originally in the distal femoral metaphysis were protruding through the femoral shaft into soft tissues of the medial thigh. Successful treatment involved removal of prominent distal screws and use of a Taylor Spatial external fixator frame to correct the deformity. Lateral soft tissue release was performed to allow patellar relocation. At 12 weeks follow up leg alignment was restored, pain resolved and the patient was mobilising. Conclusion. Femoral valgus is a possible complication of lateral plate fixation in up to 30% of pediatric distal femur fractures. With this patient's combination of deformities as an example, we suggest early hardware removal after fracture union, preventing deformities developing. If plate removal is not chosen, then continued close monitoring of the patient is necessary until skeletal maturity. Level of Evidence. Type 4 (case report)

Aims. The aim of this study was to evaluate the clinical and radiological outcomes of locking plate fixation, with and without an associated fibular strut allograft, for the treatment of displaced proximal humeral fractures in elderly osteoporotic patients. Patients and Methods. We undertook a retrospective comparison of two methods of fixation, using a locking plate without an associated fibular strut allograft (LP group) and with a fibular allograft (FA group) for the treatment of these fractures. The outcome was assessed for 52 patients in the LP group and 45 in the FA group, with a mean age of 74.3 years (52 to 89), at a mean follow-up of 14.2 months (12 to 19). The clinical results were evaluated using a visual analogue scale (VAS) score for pain, the Constant score, the American Shoulder and Elbow Surgeons (ASES) score, and the range of movement. Radiological results were evaluated using the neck-shaft angle (NSA) and humeral head height (HHH). Results. The mean forward elevation in the LP and FA groups was 125.3° (. sd. 21.4) and 148.9° (. sd. 19.8), respectively (p = 0.042), while other clinical factors showed no statistically significant differences between the groups. The changes in NSA and HHH immediately after the operation and at final follow-up were significantly better in the FA group than in the LP group (p = 0.015 and p = 0.021, respectively). Conclusion. For comminuted proximal humeral fractures in osteoporotic patients, locking plate fixation with a fibular strut allograft shows satisfactory short-term results with respect to humeral head support and maintenance of reduction, and may reduce the incidence of complications associated with fixation using a locking plate alone.

The aim of this prospective randomized controlled trial was to compare patient reported and functional outcomes, complications and costs for displaced olecranon fractures managed with either tension band wire (TBW) or plate fixation. We performed a registered prospective randomized, single blind, single centre trial in 67 patients aged between 16–74 years with an acute isolated displaced fracture of the olecranon. Patients were randomised to either TBW (n=34) or plate fixation (n=33). The primary outcome measure was the Disability Arm Shoulder and Hand (DASH) score at one-year. The baseline demographic and fracture characteristics of the two groups were overall comparable. The one-year follow-up was 85percnt;. There was a significant improvement in elbow function over the 12 months following injury in both groups (p<0.001). At one-year following surgery the DASH for the TBW group was not statistically different to the plate fixation group (12.8 vs 8.5; p=0.315). There was no significant difference between groups in terms of range of movement, Broberg and Morrey Score, Mayo Elbow Score or the DASH at all assessment points over the one-year following injury (all p≥0.05). Complication rates were significantly higher in the TBW group (63percnt;vs38percnt;; p=0.042), predominantly due to a significantly higher rate of symptomatic metalwork removal (50percnt;vs22percnt;; p=0.021). In active patients with an isolated displaced fracture of the olecranon, no difference was found in the patient reported outcome between TBW and plate fixation at one year following surgery. The complication rate is higher following TBW fixation due to a high rate of symptomatic metalwork removal

Operative management of clavicle fractures is increasingly common. In the context of explaining the risks and benefits of surgery, understanding the impact of incisional numbness as it relates to the patient experience is key to shared decision making. This study aims to determine the prevalence, extent, and recovery of sensory changes associated with supraclavicular nerve injury after open reduction and plate internal fixation of middle or lateral clavicle shaft fractures. Eighty-six patients were identified retrospectively and completed a patient experience survey assessing sensory symptoms, perceived post-operative function, and satisfaction. Correlations between demographic factors and outcomes, as well as subgroup analyses were completed to identify factors impacting patient satisfaction. Ninety percent of patients experienced sensory changes post-operatively. Numbness was the most common symptom (64%) and complete resolution occurred in 32% of patients over an average of 19 months. Patients who experienced burning were less satisfied overall with the outcome of their surgery whereas those who were informed of the risk of sensory changes pre-operatively were more satisfied overall. Post-operative sensory disturbance is common. While most patients improve, some symptoms persist in the majority of patients without significant negative effects on satisfaction. Patients should always be advised of the risk of persistent sensory alterations around the surgical site to increase the likelihood of their satisfaction post-operatively

We report the results of anterior plate fixation for symptomatic, mid-shaft clavicle non-union. The superior surface is most commonly used for plate fixation. To the best of our knowledge, there are no clinical reports where anterior plate fixation of the clavicle was used. We included 12 consecutive patients, with symptomatic mid-shaft clavicular non-union, aged between 23 and 56 years during a four-year period (1998-2002). The injury was secondary to RTA in 6 cases, sports-related in 5 and skiing in one. In three patients, the non-union was secondary to superior plating using one third tubular plate, in acute fractures. The most common complaint was anterior shoulder pain (12 cases) followed by brachialgia (4 patients). The operation was performed through an anterior approach. A 3.5mm reconstruction plate was contoured and fixed onto the anterior surface of the clavicle. Bone graft was used in all cases. The average follow up was 22 months. All 12 patients achieved union at an average union time of seventeen weeks. Compared to superior plating, anterior plating has the distinct advantage that the longer screws can be used (as the clavicle is a flat bone, and the AP diameter is larger compared to superoinferior diameter) thus improving the stability of fixation. Our results show that anterior clavicle fixation is safe and effective in achieving union, even in cases following failed superior plate fixation. We therefore recommend anterior plate fixation and bone grafting in symptomatic nonunions of mid third clavicle fractures

Introduction. Plate fixation for distal femoral fractures is a commonly used method of fracture stabilisation. Many orthopaedic surgeons traditionally do not allow their patients to weight bear for the first 6 weeks after surgery, fearing of loss of fracture reduction and metalwork failure. The aim of this study is to investigate whether the post-operative weight bearing status after plate fixation influences the outcome in terms of loss of reduction and metalwork failure. Materials & Methods. A retrospective data collection from all patients who treated in our hospital surgically for distal femoral fractures, from January 2015 until June 2017. Inclusion criteria were the operative treatment of these fractures with plate fixation. Patients who were treated with retrograde nail, primary total knee replacement or screw fixation were excluded from the study. Patient, injury and surgery demographic data was collected. The immediate post-operative weight bearing status of these patients was noted. Weight bearing status was divided into two groups – Group 1 (Non and touch weight bear – the non-weight bearing group) and Group 2 (Weight bear as tolerated / Full weight bear – the weight bearing group). Radiological data about fracture displacement or metalwork failure was collected at the six weeks and three months follow up after the operation, using a standardised measurement for displacement performed independently by two authors (EI, TA). Results. Of 70 patients, a total of 51 fractures treated with plate fixation were included to the study. The mean age of the cohort was 64.3 ±20.7 years with the majority of the patients being female (63%). Most of the patients (40%) had a complete articular distal femoral fracture, AO Type 33C. Thirty-nine patients (76%) were treated with one lateral distal femoral plate. The total number of the patients in group 1 was 32 (68%); with 17 patients (32%) in group 2. The weight bearing status did not correlate with the fracture type or the fixation type (p>0.05). None of the 6 weeks follow up radiographs revealed fracture displacement in both study groups. Four of the patients from the non-weight bearing group had >1mm displacement at the 3 months' follow-up radiographs. Fisher's exact test revealed no statistically significant difference between the two study groups in both follow-up time points (p=0.55). Two of the patients in the non-weight bearing group had their plate broken at the 3 months follow up and required revision fixation. Conclusion. By reviewing the outcomes in terms of fracture displacement and metalwork failure following plate fixation of distal femoral fractures, early weight bearing of these patients do not jeopardise the outcome of the operation

Distal radius fractures (DRF) are the most common fracture type in all age groups combined. Unstable DRF may be surgically managed with volar or dorsal plate fixation. Dorsal plating has traditionally been associated with decreased range of motion (ROM). However, this assumption has not been recently assessed to determine whether functional ROM is achievable (approximately 54o of flexion and 60o of extension) with recent advances in lower profile dorsal plate design. The aim of this study was therefore to compare ROM and patient reported outcome measures between volar and dorsal plating methods for DRF. A meta-analysis was performed to directly compare ROM and DASH scores between dorsal and volar plate fixation for DRF. Separate literature searches for each plating method were performed using MedLine and EMBase on January 28, 2018. Exclusion criteria consisted of non-English articles, basic science articles, animal/cadaver studies, case studies/series, combined operative approaches, papers published more than 20 years ago and paediatric studies. Only articles with at least one year patient follow-up and a) ROM and AO distal radius fracture classification, or b) DASH scores were included. Raw data was extracted from all articles that met inclusion criteria to compile a comprehensive dataset for analysis. Descriptive statistics with z-score comparison for AO classification or a two-tailed independent samples t-test for ROM and DASH scores for dorsal versus volar plating were performed. Significance was defined as p < 0 .05. After rigorous screening, 6 dorsal plating and 43 volar plating articles met inclusion criteria for ROM/AO classification versus 6 dorsal plating and 44 volar plating articles for DASH scores. The weighted means of flexion (dorsal 54.9o, SD 9.3, n=257, volar 61.3o, SD 11.5, n=1906) and extension (dorsal 60.0o, SD 12, n=257, volar 62.8o, SD 11.4, n=1906) were statistically significantly different (both p < 0 .001) between the two plating methods. The volar plating group had a significantly higher proportion of AO type C fractures (dorsal 0.5, n =169, volar 0.6, n=1246, p < 0 .001). The weighted means of reported DASH scores were not significantly different between dorsal (14.01, SD 14.8) versus volar (13.6, SD 12.8) plating (p=0.54). Though mean wrist flexion and extension were statistically different between the dorsal versus volar plating methods, the difference between group means was less than 5o, which is unlikely to be clinically significant. Additionally, we did not find a significant difference in DASH scores between the two plating methods. Taken together, these findings imply that the statistical difference in ROM outcomes are likely not clinically significant and should therefore not dictate choice of plating method for fixation of DRF

Purpose. Open reduction and plate fixation of displaced mid-shaft clavicle fractures has gained significant popularity following a recent multi-center randomized control trial. The purpose of this study is to describe the incidence of reoperation following plate fixation of displaced mid-shaft clavicle fractures. The secondary objective is to determine if plate design influences the incidence of reoperation. Method. A retrospective search of our hospital database was performed to identify subjects treated with plate fixation for a displaced clavicle fracture between 2001 and 2009. Radiographs and medical records were used to identify demographic data, fracture classification, plate design, and reoperation events. Only mid-shaft (AO/OTA 15-B) fractures treated with either a Low-Contact Dynamic Compression (LCDC) plate or Pre-contoured Locking (PCL) plate were included. Results. 144 subjects were included in the study. The mean age was 36 years (95% CI 33 38 years) and the mean duration of follow-up was 60 weeks (95% CI 46 74 weeks). 60% of included fractures were wedge pattern (15-B2), followed by 35% simple (15-B1) fractures, and 5% complex (15-B3) fracture patterns. Pre-contoured locking plates were used in 92 cases (64%) and LCDC plates were used in the remaining 52 subjects (36%). 21 subjects (15%) underwent reoperation: 17% of subjects treated with LCDC plates and 13% of subjects treated with PCL plates (p=0.62). Indications for reoperation included painful hardware (86%), hardware failure (9%), and refracture (5%). There was no association between reoperation and age (p = 0.23), gender (p = 0.56), fracture type (p = 0.53), or plate design (p = 0.49). Conclusion. This study represents a large series of displaced clavicle fractures treated with open reduction and plate fixation. Reoperation following plate fixation is relatively common and is primarily due to painful hardware. No difference in reoperation rates between LCDC and pre-contoured plates could be detected in the current sample size

Only articles with at least one year patient follow-up and a) ROM and AO-OTA distal radius fracture classification, or b) DASH scores were included.

After rigorous screening, six dorsal plating and 43 volar plating articles met inclusion criteria for ROM/AO-OTA classification versus six dorsal plating and 44 volar plating articles for DASH scores. The weighted means of flexion (dorsal 54.9 degrees, SD 9.3, n=257, volar 61.3 degrees, SD 11.5, n=1906) and extension (dorsal 60 degrees, SD 12, n=257, volar 62.8 degrees, SD 11.4, n=1906) were significantly different (both p < 0 .001) between the two plating methods. The volar plating group had a significantly higher proportion of type C fractures (dorsal 0.5, n =169, volar 0.6, n=1246, p < 0 .001). The weighted means of reported DASH scores were not significantly different between dorsal (14, SD 14.8) versus volar (13.6, SD 12.8) plating (p=0.54). Though mean wrist flexion and extension were statistically different between the dorsal versus volar plating methods, the difference between group means was less than 5-degrees, which is unlikely to be clinically significant. Additionally, there was no significant difference in DASH scores between the two plating methods. Taken together, these findings imply that the statistical difference in ROM outcomes are likely not clinically significant and should therefore not dictate choice of plating method for fixation of DRF

Fractures repair by two mechanisms; direct fracture healing and indirect fracture healing via callus formation. Research concerning the effects of bisphosphonate on fracture repair has solely assessed indirect fracture healing. Patients with osteoporosis on bisphosphonates continue to sustain fragility fractures. A proportion of osteoporotic fractures require plate fixation. Bisphosphonates impair osteoclast activity and therefore, may adversely affect direct fracture healing that predominates with plate fixation. Five skeletally mature Sprague-Dawley rats received daily subcutaneous injections of 1mg/kg Ibandronate (IBAN). Similarly, five control rats received saline (CONTROL). Three weeks following commencement of injections a tibial osteotomy was rigidly fixed with compression plating similar to that seen in routine clinical practice. Fracture healing was monitored with radiographs. Six weeks post plate fixation, animals were sacrificed. Radiographs were performed of the extricated tibiae following plate removal. The visibility of the osteotomy site was scored as totally visible, partially visible or absent as previously described. Mechanical testing was conducted on the healing osteotomies via 4-point bending. Fractures healed without visible external callus. In the IBAN group three animals had totally visible osteotomy lines and two had partially visible osteotomy lines. The CONTROL group had three animals with absent osteotomy lines and two with partially visible osteotomy lines. The mean (±SD) stress at failure for the healing tibial osteotomies at 6 weeks was 28.8 (±23.97)MPa in the IBAN group and 37.4(±29.20) MPa in the CONTROL group (p=0.62). Our results indicate that Ibandronate adversely affected direct fracture repair as demonstrated by the radiographic density of the fracture line. The strength of the repair was reduced but this did not reach statistical significance. Our results suggest that a sample size of 220 animals is required to detect a 15% difference (alpha 0.05, beta 0.2) which suggests the effect of bisphosphonates on direct fracture repair may be small

Background. Surgical management of calcaneus fractures is demanding and has a high risk of wound complications. Traditionally these fractures are managed with splinting until swelling has subsided. We describe a novel protocol for the management of displaced intra-articular calcaneus fractures utilising a temporizing external fixator and staged conversion to plate fixation through a sinus tarsi approach. The goal of this technique is to allow for earlier treatment with open reduction and internal fixation, minimise the amount of manipulation required at the time of definitive fixation and reduce the wound complication rate seen with the extensile approach. Methods. The records of patients with displaced calcaneus fractures from 2010–2014 were retrospectively reviewed. A total of 10 patients with 12 calcaneus fractures were treated with this protocol. All patients underwent ankle-spanning medial external fixation within 48 hours of injury. Patients underwent conversion to open plate fixation through a sinus tarsi approach when skin turgor had returned to normal. Time to surgery, infection rate, wound complications, radiographic alignment, and time to radiographic union were recorded. Results. The average Bohler's angle improved from 13.2 (range −2 to 34) degrees preoperatively to 34.3 (range 26 to 42) degrees postoperatively. The average time from external fixation to conversion to internal fixation was 4.8 (range 3 to 7) days. There were no immediate post-surgical complications. The average time to weight bearing was 8.5 weeks. The average time to radiographic union was 9.5 (range 8 to 12) weeks. There were no infections or wound complications at the time of last follow-up. Conclusions. Early temporizing external fixation for the acute management of displaced calcaneus fractures is a safe and effective method to reduce and stabilise the foot and may decrease the time to definitive fixation. In our series there were no complications related to the use of the external fixator. Level of Evidence. IV Retrospective case series

The results of immediate plate fixation of 97 open fractures of the tibial shaft in 95 patients are reported. Significant joint stiffness occurred in 11.4% and angular malunion of greater than 5 degrees in any plane was seen in 3.1%. The infection rate was 10.3%. However, even in those cases which develop delayed union or other complications, plate fixation of open fractures can produce excellent recovery of limb function

Tension band wire fixation continues to be the most popular method of fixation for displaced olecranon fractures despite several biomechanical studies questioning the validity of the tension band concept. Our aim was to compare the outcome of the tension band wire (TBW) method with plate fixation. 58 consecutive olecranon fractures underwent internal fixation in 58 patients between September 2000 and December 2004. There were 30 male and 28 female with a mean age at the time of surgery of 52.5 years for the TBW group (range 19 to 88) and 46.1 for the plate group (range 19 to 72). Patients were excluded if they were less than 16 years of age. Choice of fixation was based on surgeon preference, fracture pattern and presence of associated injuries. 43 patients were managed with the AO tension band technique and 15 with plate fixation. Clinical assessment and functional analysis was performed using Helm’s scoring system. Radiographic assessment was performed to assess the quality of reduction. All fractures were displaced and classified according to Colton’s classification. Mean follow up was 13 months (range 6 to 18) and similar for the two groups. For the TBW group 41 (95 %) had a fair or good result. 27 (62.8%) patients had symptomatic metal prominence requiring implant removal. In the plate fixation group 14 (94%) had a fair or good functional result despite having more complex fractures. Only 2 (18%) patients required implant removal for symptomatic metalwork, including one failure due to a technical problem. Similar functional results were seen with plating and tension band wiring of displaced olecranon fractures. Despite meticulous technique, tension band wire fixation still has an unacceptably high complication rate with symptomatic metal prominence requiring further surgery. To avoid this problem, we recommend plating, even for the more simple olecranon fractures

Aim. The aim of this study was to compare the cost-effectiveness of intramedullary nail fixation and ‘locking’ plate fixation in the treatment of extra-articular fractures of the distal tibia. Patients and Methods. An economic evaluation was conducted from the perspective of the United Kingdom National Health Service (NHS) and personal social services (PSS), based on evidence from the Fixation of Distal Tibia Fractures (UK FixDT) multicentre parallel trial. Data from 321 patients were available for analysis. Costs were collected prospectively over the 12-month follow-up period using trial case report forms and participant-completed questionnaires. Cost-effectiveness was reported in terms of incremental cost per quality adjusted life year (QALY) gained, and net monetary benefit. Sensitivity analyses were conducted to test the robustness of cost-effectiveness estimates. Results. Mean NHS and PSS costs were significantly lower for patients treated with an intramedullary nail than for those treated with a locking plate (-£970, 95% confidence interval (CI) -1685 to -256; p = 0.05). There was a small increase in QALYs gained in the nail fixation group (0.01, 95% CI -0.03 to 0.06; p = 0.52). The probability of cost-effectiveness for nail fixation exceeded 90% at cost-effectiveness thresholds as low as £15 000 per additional QALY. The cost-effectiveness results remained robust to several sensitivity analyses. Conclusion. This trial-based economic evaluation suggests that nail fixation is a cost-effective alternative to locking plate fixation. Cite this article: Bone Joint J 2018;100-B:624–33

Aims. To synthesise the literature and perform a meta-analysis detailing the longitudinal recovery in the first two years following a distal radius fracture (DRF) managed with volar plate fixation. Materials and Methods. Three databases were searched to identify relevant articles. Following eligibility screening and quality assessment, data were extracted and outcomes were assimilated at the post-operative time points of interest. A state-of-the-art longitudinal mixed-effects meta-analysis model was employed to analyse the data. Results. The search identified 5698 articles, of which 46 study reports met the selection criteria. High levels of disability and impairment were reported in the immediate post-operative period with subsequently a rapid initial improvement followed by more gradual improvement for up to one year. The results highlight that the period associated with the greatest physical recovery is in the first three months and suggest that the endpoint of treatment outcomes is best measured at one year post-surgery. Conclusion. Clinically meaningful improvements in outcomes can be expected for 12 months, after which progress plateaus and reaches normal values. This paper adopted a novel approach to meta-analyses in that the research question was of a longitudinal nature, which required a unique method of statistical analysis.

Debate surrounds the optimum operative treatment of periprosthetic distal femoral fractures (PDFFs) at the level of well fixed femoral components; lateral locking plate fixation (LLP-ORIF) or distal femoral replacement (DFR). To determine which attributed the least peri-operative morbidity and mortality we performed a retrospective cohort study of 60 consecutive unilateral PDFFs of Su types II (40/60) and III (20/60) in patients ≥60 years; 33 underwent LLP-ORIF and 27 underwent DFR. The primary outcome measure was reoperation. Secondary outcomes included perioperative complications and functional mobility status. Kaplan Meier survival analysis was performed. Cox multivariable regression analysis identified risk factors for reoperation after LLP-ORIF. Mean length of follow-up was 3.8 years (range 1.0–10.4). One-year mortality was 13% (8/60). Reoperation rate was significantly higher following LLP-ORIF: 7/33 vs 0/27, p=0.008. For the endpoint reoperation, five-year survival was better following DFR: 100% compared to 70.8% (51.8 to 89.8 95%CI) (p=0.006). For the endpoint mechanical failure (including radiographic loosening) there was no difference at 5 years: ORIF 74.5% (56.3 to 92.7); DFR 78.2% (52.3 to 100), p=0.182). Reoperation following LLP-ORIF was independently associated with medial comminution: HR 10.7 (1.45 to 79.5, p=0.020). Anatomic reduction was protective against reoperation: HR 0.11(0.013 to 0.96, p=0.046). When inadequately fixed fractures were excluded differences in survival were no longer significant: reoperation (p=0.156); mechanical failure (p=0.453). Reoperation rates are higher following LLP-ORIF of low PDFFs compared to DFR. Where adequate reduction, proximal fixation and augmentation of medial comminution is used there is no difference in survival between LLP-ORIF and DFR

Purpose: Nonunion of the humeral shaft is an uncommon complication of diaphyseal fractures. The rate of nonunion reported in the literature is nevertheless very variable, ranging from 1 to 10%. There are many causal and favouring factors often related to a technical error or poor therapeutic indication. There are several ways to treat humeral shaft fractures (orthopaedic treatment, locked centromedullary nail, ascending pinning, plate fixation, external fixation). Rigorous technique and rigorous indications are the key to success. Material and methods: We reviewed 35 patients with aseptic nonunion of the humeral shaft between 1995 and 2000. The nonunion resulted from imperfect initial treatment in 24. Mean age was 44 years; fracture of the mid third of the shaft was oblique or transverse in general; all types of initial treatments had been used but ascending pins predominated (16 cases). All patients were reoperated for external plate fixation with a cancellous or corticocancellous bone graft after identifying the radial nerve. Results: All patients achieved consolidation within a mean delay of 15 weeks with good shoulder (mean elevation 135°) and elbow (mean 10–130°) amplitudes. There were two cases of transient radial paresis with spontaneous recovery. Only two patients experienced mild arm pain that did not required long-term antalgesic treatment. There were no injuries to the femorocutaneous nerve at the site of graft harvesting. Discussion: Plate fixation for nonunion of the humerus is widely described in the literature. The main complications with this method include radial paralysis and infection. For this reason, several recent reports have advocated locked nailing or external fixation of the Ilizarov type. These methods are technically difficult and are not free of their own complications. We thus recommend screw plate fixation (eight cortical screws on either side of the nonunion) associated with cancellous bone grafts. The results in our series with almost no complications favour this option

There are many management solutions for the fixation of Periprosthetic fractures with intact stem of Hip and shoulder arthroplasties. The Bio Mechanics of single plate application are unlikely to be strong enough to commence mobilisation and its effectiveness against torsional strain with an osteoporotic bone quality is of concern. Double plate fixation as discussed at the last South African Orthopaedic Congress by Mr Floyd et al is another option but this again may have some biomechanical concerns and biological compromise at the fracture site due to periosteal stripping. Implant revision with a longer stem is a bigger surgical insult to a potentially frail group of patients with questionable bone quality. We report a short series of 16 peri-prosthetic fractures with intact stem that are managed with Zimmer cable plate fixation System. The results were very satisfactory and we consider this an attractive option to be considered in the management of this difficult presentation. This is a retrospective study. We present the results of 13 Periprosthetic Femoral Shaft fractures and 3 humeral periprosthetic fractures in 16 patients treated with cable plate fixation system. Majority of the patients were over 60 years with an ASA rating of 3–4. The procedures were performed in a district general hospital in the UK between August 2001 to December 2005. The patients presented with in 1–20 years following initial Arthroplasty. All the fractures were fixed with Zimmer cable plate fixation system. An 8 hole plate was most commonly used for femoral fractures through the lateral approach for TYPE 2 fractures. The proximal end of the plate was secured with 3–4 cable ties. Early partial weight bearing was encouraged. The majority of the patients were discharged within 12 weeks. Of the 3 humeral fractures union was achieved at 12 weeks in 2. There was 1 case of implant failure due to a further fracture noted in a manic depressive patient, who was not compliant. All proximal femoral fractures showed evidence of clinical and radiological union by 6 months. The majority (7/13) had united within 20 weeks. There were no complications noted. We recommend this effective method should seriously be considered in the management of this difficult and increasingly occurring complication in a frail population

Background: First MTP joint arthrodesis is a well established and very common procedure for painful arthrosis. Plate fixation method has been used with successful outcome (97–100%) by few authors but it is yet to be accepted universally for fear of complications. Aim: To evaluate clinical and radiological outcome of first MTP fusion using low profile Acumed plate. Methods: We retrospectively reviewed 125 patients who had 1st MTP arthrodesis (over 6 year period) for painful Hallux Rigidus not relieved by conservative means and for rheumatoid forefoot reconstruction. The preoperative evaluation included a subjective questionnaire, physical exam, AOFAS hallux score and radiographic measurements. Post-operatively, all patients were mobilised with heel weight bearing shoes for six weeks. All patients had follow up of minimum 6 months(range 6 months to 6 years). At the final follow-up all patients had answered a questionnaire which evaluated any limitations of daily activity and restrictions in footwear. Radiological measurements included union of the arthrodesis and various angles (valgus, intermetatarsal and dorsiflexion). Results: Of the 125 patients we had final reviews for 103 patients. The mean AOFAS improved from 40 to 82. The individual components of AOFAS i.e. pain, walking ability and alignment improved significantly. All patients but one had radiological evidence of fusion at mean of 6 weeks (range 6–8weeks) allowing them to walk with normal footwear. The mean dorsiflexion angle was 15° (range 13 °–18 °). The patient with non-union had re-arthrodesis with bone grafts using the revision plate. Two patients with rheumatoid arthritis required removal of plate for infection and wound breakdown. No plate failure occurred in any of the patients. Conclusion: The plate fixation is a reliable method for 1st MTP joint fusion that allows for a predictable fusion in a satisfactory alignment with low complication rate. The stability of the fixation allows for early mobilization without need for plaster immobilization and early return to functional activities

Introduction. Metatarsocuneiform (MTC) fusion is a standard treatment for arthritis, instability, and deformity of these joint. The MTC fusion achieves a good clinical outcome, but nonunion rates up to 12% have been reported. There are different methods for fixation of first MTC joint arthrodesis. Our aim was to compare the biomechanical characteristic of internal and external fixation constructs. Hypothesis. Plantar plate fixation provides higher construct stiffness and endurance stability than intraosseous fixation. Materials & Methods. Seven pairs of fresh-frozen human specimens were used in a matched pair test. In one foot the MTC joint was supplied with a plantar plate. On the other foot intraosseous-screw fixation was perfomed. The specimen constructs were loaded in a 4 point bending test. Parameters obtained were initial stiffness and number of cycles to failure. Failure was defined as displacement of more than 3 mm plantar gapping. Results. The intraosseous-screw fixation group showed significantly (p=0.002) less cycles to failure (n=2946) than the plantare plate (n=7517). The initial stiffness was 131 N/mm for the plantare plate and 43 N/mm for the intraosseous implant (p=0.005). Discussion & Conclusion. Plantar plate fixation of the first MTC fusion created a stronger and stiffer construct than intraosseous fixation. This was likely due to the plantar and dorsal implant position. A stiffer construct can reduce the risk of non-union and shorten the period of nonweight-bearing

The purpose of this study was to investigate patient-based functional outcome and objectively measure strength following plate fixation of fractures of both bones of the forearm. Twenty-five subjects were clinically and radiographically reviewed. Strength of elbow flexion, extension, supination, pronation, wrist flex-ion, extension and grip were significantly reduced in the injured arm. (p< 0.01, range 62%–84% of normal). Mean (+/− SE) DASH score was 19.5 +/− 4.0 and eighty-eight percent (22/25) scored good to excellent on the Gartland-Werley scale (mean 4.04 +/− 0.91). No statistical difference in mean maximal radial bow (MRB) or location of MRB between injured and non-injured arm was found. The purpose of this study was to investigate functional outcome and objectively measure strength following plate fixation of fractures of both bones of the forearm (BBOF). Anatomic reduction was associated with good to excellent functional outcome. However strength of the elbow, forearm, wrist and grip were significantly reduced in the injured arm. Despite good to excellent functional outcome following this injury, significant reduction in strength of the upper extremity should be expected, and thus is an area for potential improvement in post-operative care. Twenty-five subjects (M/F 19/6, mean age 47.6 (range 20–71)) treated with plate fixation for fractures of BBOF were clinically and radiographically reviewed. Mean duration of follow-up was 5.7 years (range 2–13.4 y). Post-operative protocol included short-term immobilization followed by active-assisted ROM and strengthening starting between four and six weeks. Isometric muscle strength was objectively measured with the Baltimore Therapeutic Equipment work simulator (model WS-20). Strength of elbow flexion (72% of non-injured arm, p< 0.0001), elbow extension (84%, p=0.0004), forearm supination (75%, p=0.005), forearm pronation (69%, p< 0.0001), wrist flexion (81%, p=0.009), wrist extension (62%, p< 0.0001) and grip (70%, p< 0.0001) were all significantly reduced in the injured arm. Mean (+/− SE) DASH and Gartland-Werley scores were 19.5 +/− 4.0 (range 0–61) and 4.04 +/− 0.91 (range 0–15) respectively. Eighty-eight percent (22/25) scored good to excellent on the Gartland-Werley scale. No statistical difference in mean maximal radial bow (MRB) between injured and non-injured arm was found (mean +/− SE, 1.42 +/− 0.07 vs 1.58 +/− 0.05 respectively) or in location of MRB (61% vs 59%)

Introduction and Aims: Patient-based functional outcome and strength following plate fixation of diaphyseal fractures of the radius and ulna is unknown. Therefore, the purpose of this study was to investigate patient-based functional outcome and objectively measured strength following plate fixation of fractures of both bones of the forearm (BBOF). Method: Twenty-five subjects (M/F 19/6, mean age 47.6 (range 20–71) treated with plate fixation for fractures of BBOF were clinically and radiographically reviewed. Mean duration of follow-up was 5.7 years (range 2–13.4 years). Post-operative protocol included short-term immobilisation followed by active-assisted ROM and strengthening starting between four and six weeks. All subjects were assessed in person at follow-up with a detailed examination of strength of their injured and non-injured arms. Isometric muscle strength was objectively measured with the Baltimore Therapeutic Equipment work simulator (model WS-20). Standardised anteroposterior and lateral radiographs were made of both forearms. Results: Strength of elbow flexion (72% of non-injured arm, p< 0.0001), elbow extension (84%, p=0.0004), forearm supination (75%, p=0.005), forearm pronation (69%, p< 0.0001), wrist flexion (81%, p=0.009), wrist extension (62%, p< 0.0001) and grip (70%, p< 0.0001) were all significantly reduced in the injured arm. Mean (+/− SE) DASH and Gartland-Werley scores were 19.5 +/− 4.0 (range 0–61) and 4.04 +/− 0.91 (range 0–15) respectively. Eighty-eight percent (22/25) scored good to excellent on the Gartland-Werley scale. No statistical difference in mean maximal radial bow (MRB) between injured and non-injured arm was found (mean +/− SE, 1.42 +/− 0.07 vs 1.58 +/− 0.05 respectively) or in location of MRB (61% vs 59%). Conclusion: Restoration of anatomic alignment with stable internal fixation following BBOF fracture results in good to excellent functional outcome. Despite this, significant reduction in strength of the elbow, forearm, wrist and grip should be expected following this injury, and is an area for potential improvement in post-operative care

Reviewing 40 consecutive cases over a two-year period, we tested the efficacy of variable screw plate fixation postoperatively. A Codman plate was used in all cases. We compared radiological preoperative measurements of the kyphotic angle and disc height with immediate postoperative measurements and measurements at a mean of eight months postoperatively. In no case was there an increase in kyphotic angle. Disc height remained within two mm of that shown on immediate postoperative radiographs. We concluded that satisfactory results are obtained with variable screw plate fixation, with no compromised stability

Purpose: Management of the unstable or comminuted displaced fractures of the distal radius is difficult. We report our experience treating these fractures with AO volar plate fixation. An attempt to introduce a new radiological classification for the accuracy of surgical reduction is made. The classification includes 10 criteria and 100 points. Methods: 124 patients had volar plate fixation performed between June 2000 and May 2003 using AO volar plate. We reviewed clinically and radiologically 101 patients; 60 were type C and 41 were type A (after failed conservative treatment). The average follow up is 37 months (24 – 57). The average age is 46 years (19 – 81). Postoperative regimen consisted of immediate physiotherapy and a wrist splint for three weeks. Cooney’s modification of Green and O’Brien and Sarmiento’s modification of Gartland and Werley were used for clinical assessment. Lidstorm and Frykman used for radiological assessment. Results: At final follow up the means of distal radius parameters were: volar tilt of 9 degrees, radial inclination of 22 degrees, radial height is 11mm and palmer cortical angle of 32 degrees. The mean dorsiflexion was 61 degrees, palmer flexion was 59 degrees, pronation was 80 degrees and supination was 76 degrees. Grip strength was 86 percent of the opposite side. The average DASH score was 13.6. There was 14 poor results, 6 of them had significant loss the initial reduction. There was significant correlation between our classification and the clinical outcome. Conclusion: AO volar plate fixation of unstable distal radius fractures provides strong fixation that maintains reduction and allows early mobilisation

Purpose of Study. Debate exists in the literature about the surgical management of sub-axial cervical burst fractures regarding the approach and types of fixation of these injuries. Our Acute Spinal Injury (ASCI) unit prefers anterior only cervical corpectomy and plate fixation in the management of these injuries. The objective of this study was to radiologically assess the long term outcomes (minimum 2 yrs) of our series. Patients and Methods. Patients were identified using the Acute Spinal Injury Unit (ASCI) database that had had anterior only corpectomy and plate fixation for trauma as a standardised procedure between 2006 and 2009. Initial post-op radiological review included the sagittal alignment, hardware characteristics and surgical technique. Radiological review after a minimum of 24 months involved the union, sagittal alignment, hardware characteristics, graft incorporation and adjacent level degeneration at the site of injury. Results. A total of 51 patients were identified but only 11 were available for review at the minimum 24 months. There were 10 males and 1 female with an average age of 28.1years (18–62). The follow up duration was on average 50.6months (27–71) median 60 months. The levels fused were C3-5 (2), C4-6 (5), C5-7 (3), and C4-7 (1 double level). There was NO metalwork failure, NO screw osteolysis and a varying degree of degenerative changes but a 100% FUSION RATE. The average loss of cervical lordosis was 2.5 ° over the follow up period. Conclusion. Anterior stand alone cervical corpectomy and plating alone appears to be a safe, cost effective and time saving alternative in the management of cervical burst fractures in the sub axial spine with no significant long term complications. NO DISCLOSURES

Aims. Intercalary allografts following resection of a primary diaphyseal tumour have high rates of complications and failures. At our institution intercalary allografts are augmented with intramedullary cement and fixed using compression plating. Our aim was to evaluate their long-term outcomes. Patients and Methods. A total of 46 patients underwent reconstruction with an intercalary allograft between 1989 and 2014. The patients had a mean age of 32.8 years (14 to 77). The most common diagnoses were osteosarcoma (n = 16) and chondrosarcoma (n = 9). The location of the tumours was in the femur in 21, the tibia in 16 and the humerus in nine. Function was assessed using the Musculoskeletal Tumor Society (MSTS) scoring system and the Toronto Extremity Salvage Score (TESS). The survival of the graft and the overall survival were assessed using the Kaplan-Meier method. Results. The median follow-up was 92 months (4 to 288). The mean MSTS 87 score was 29.1 (19 to 35), the mean MSTS 93 score was 82.2 (50 to 100) and the mean TESS score was 81.2 (43 to 100). Overall survival of the allograft was 84.8%. A total of 15 patients (33%) had a complication. Five allografts were revised for complications and one for local recurrence. Conclusion. Intercalary allografts augmented with intramedullary cement and compression plate fixation provide a reliable and durable method of reconstruction after the excision of a primary diaphyseal bone tumour, with high levels of function and satisfaction. .

Injuries to the tarsometatarsal joint complex are uncommonly recognised. Many treatment modalities have been advocated. In recent years anatomic reduction and temporary rigid fixation with trans -articular screws has become popular. This is a study conducted over a period of at least two years. It reviews the management and subsequent outcome of a series of consecutive patients with an average age of 40.1 who suffered tarsometatarsal injury, or Lisfranc fracture. Anatomic or near anatomic reduction was achieved using temporary bridging plate fixation of the TMT joints and occasionally also with second metatarsal base medial cuneiform screw fixation. Two years post surgery a good or excellent functional result was generally achieved; however midfoot stiffness was a common problem

The traditional treatment method of pediatric femoral shaft fracture has been traction and spica casting.This method is safe but prolonged immobilization, frequent X-ray , pin tract infections are some of the disadvantages. Internal fixation has become an alternative treatment in especially children between 6-10 years. Surgical treatment has been advocated for children who have multiple injuries or severe head injury. Compression plate fixation provides rigid and stable fixation but requires extensive dissection. Fixation of the fractures with flex-ible intramedullary nailing is another alternative treatment method and is safe and effective especially in simple transverse and short oblique fractures.In the current study we tried to evaluate the results of flexible intramedullary nailing and compare them with compression plate fixation. Thirty four patients with 36 femoral segments were included to the study. Clinical and radiological records of the patients were evaluated retrospectively. Patient’s demographic data, mechanism of injury, type of treatment , duration of the operation ,age ,side were obtained from the files. 19 femoral segments were treated with compression plating .There were 13 male and 5 female patients in this group. The mean age was 7.7 (6-10).The mean operation time was 100 minutes.(75-160 minutes- time between entering and leaving the operation room )Average time to healing was calculated as 7.7 (4-10 ) months.In this group, four femoral segment non-unions and implant failures occured in 6-10 months time .These patients were managed with titanium elastic nail.17 femoral segments were treated with titanium elastic nail ( TEN ).There were 10 male and 6 female patients in this group.The mean age of the patients were 7.9 years ( 7-10 ) .There were four patients managed with plate fixation previously . Revision surgery was done with implant removal and open reduction.The remaining 12 patients were operated with closed reduction and nailing. The mean operation time for this group was 86 ( 45-135) minutes . No immobilization method was used and partial weigth bearing permitted after the surgery.The mean healing time was 4 ( 3-7 ) months for this group. As we compare the both groups , the results were similiar. Average operation time was shorter in the nailing group but there were no statistically significant difference between the two groups. ( p> 0.05) . Average healing time was statistically significantly shorter in the nailing group. ( p= 0.038). It is generally accepted that plating is a traditionally safe and effective method; this study demonstrates that flexible intramedullary nailing maintains shorter operation time and shorter time to healing . The lack of need of post-operative immobilization , and small incisions for the insertion of the nail which is cosmetically more acceptable are the other advantages of this method. Conclusion: Internal fixation with flexible intramedul-lary nailing of the femoral fractures in pediatric age group is an advocatable solution

Introduction and Aims: The purpose of the study was to determine whether the addition of screws improved the fixation of the tibial base plate when using an uncemented total knee replacement. Method: In June 1999 a prospective randomised double blind study on tibial base plate fixation was started at our institution after Ethics Committee approval. Patients were randomly allocated to either having or not having supplementary screws inserted through the base plate. To date, 138 arthroplasties have been performed and 119 are available for study. Of these, 56 have screws through the base plate and 63 do not. Assessment was of the position of the components of the prostheses, as well as the presence of any radiological lucent lines. Results: The study is ongoing, and updated results will be presented. After a minimum of 12 months follow-up, 27 patients have some radiolucent lines at the prosthesis-bone interface on the tibial component of the knee replacement. Fourteen occurred where screws had been used and 13 when screws had not. One tibial tray subsided into the tibia without failure of fixation. No screws had been used in this case. Statistically no difference could be demonstrated between the two groups. Conclusion: The early results of our study question the value of supplementing base plate fixation in uncemented total knee replacements, especially considering the additional cost of the screws and the potential detrimental consequences of the screws

Background and Aims: Plate fixation of acute mid-shaft clavicle fractures is becoming increasingly popular. However limb and life threatening complications such as injury to the subclavian vessels have been reported. One possible solution to reduce the risk of this complication is the use of unicortical screw fixation. The aim of this study was to compare biomechanical properties of pre-contoured plate fixation using different screw fixation modes in a mid-shaft clavicle fracture model. Methods: Fourth generation biomechanical clavicle sawbones with a mid-shaft osteotomy were plated in one of three modes: nonlocking bicortical, locking bicortical and locking unicortical mode. The specimens were then tested to failure in four-point bending and pull-off tests. Results: Failure due to fracture through the sawbone was more common in nonlocking bicortical mode while plate bending was more common in the locking bicortical group. The ultimate load at failure was significantly lower in the locking bicortical group compared to the nonlocking bicortical group, however there was no significant difference between the locking unicortical group and nonlocking bicortical group. In the pull-off tests 100% of nonlocking bicortical and locking bicortical plates failed by fracture of the sawbone. 100% of the locking unicortical plates failed by plate and screw pull-off from the sawbone. The load at failure was highest for the locking unicortical plate but this was not significantly different to the other groups. Conclusion: This study shows that specimens fixed with locking unicortical screw fixation withstood comparable or superior loads in four-point bending and pull-off test when compared to nonlocking bicortical and locking bicortical screw fixation. In addition both locking screws and unicortical screws appear to provide a protective effect against periprosthetic sawbone fracture. Locking unicortical screw fixation of pre-contoured plates may be a viable alternative in the fixation of mid-shaft clavicle fractures

Aims

The purpose of this study was to compare reoperation and revision rates of double plating (DP), single plating using a lateral locking plate (SP), or distal femoral arthroplasty (DFA) for the treatment of periprosthetic distal femur fractures (PDFFs).

In June 1999 a randomised double-blind study on tibial base plate fixation was started to determine whether, when using the Profix® total knee replacement, the addition of screws improved the fixation of the tibial base plate. To date 138 total knee arthroplasties (THAs) have been performed, 119 of which were available for study. Selected randomly, 56 patients had supplementary screws inserted through the base plate and 63 did not. After a minimum of 12 months follow-up, 27 patients had some radiolucent lines at the prosthesis-bone interface on the tibial component. These lines occurred in 14 cases with supplementary screws and 13 without screws. In one patient without supplementary screws, the tibial tray had subsided into the tibia. Statistically there was no apparent difference between the two groups. The early results of our study raise questions about the value of supplementing base plate fixation in uncemented THAs, especially considering the additional cost of the screws and their potentially detrimental consequences

Torsional deformities of the tibia are common in children, but in the majority both the torsion and the associated disturbance of gait resolve without intervention. There are, however, a significant number of children and adults with neuromuscular disease who present with pathological tibial torsion, which may require surgical correction. We conducted a prospective study in two centres, to investigate the outcome of supramalleolar derotation osteotomy of the tibia, using internal fixation with the AO-ASIF T plate. A range of outcome variables was collected, prospectively, for 57 patients (91 osteotomies), including thigh foot angle, foot progression angle, post-operative complications and serial radiographs. Correction of thigh foot angle and foot progression angle was satisfactory in all patients. Three major complications were recorded; one aseptic nonunion, one fracture through the osteotomy site after removal of the plate and one distal tibial growth arrest. We found that supramalleolar derotation osteotomy of the tibia, with AO-ASIF T plate fixation is an effective method for the correction of torsional deformities of the tibia and the associated disturbances of gait in children and adults with neuromuscular disease, with a 5.3% risk of major complications

Purpose of the study: Locked plating is an attractive alternative to external fixation for the fixation of distal shaft fractures of the radius, particularly in cases with metaphyseal comminution. The purpose of this study was to assess prospectively outcome with locked anterior plate fixation in a series of 43 complex fractures of the distal radius treated between October 2003 and November 2004. Material and methods: The AO LCP 3.5 plate (Synthes) was used. The series included 27 women and 15 men, mean age 55.5 years (range 17–83 years). We included fractures with major metaphyseal comminution according to the M.E.C classification established by Laulan (18 M2, 14 M3, and 9 M4). According to the AO classification, there were nine extra-articular fractures (eight A3 and one A2) and 35 articular fractures (ten B3, two C1, four C2, and seventeen C3). Posterior displacement was noted for 22 fractures. In eight cases plate fixation was a second intention procedure due to secondary displacement occurring on average eight days (range 3–21 days) after trauma for a fracture initially treated with infrafocal pinning. An epiphyseal locking screw was used in all cases. An antebrachiopalmar immobilization orthesis was worn for six weeks on average (range 3–9 weeks). The first-intention anterior plating was combined with an intrafocal posterior pin for 13 patients and with an external fixator in one. Radiographic outcome was reported in terms of joint congruency and using the SOFCOT symposium criteria for the 41 patients reviewed at bone healing. Results: Anatomic restitution was achieved in 23 patients (55%). There were two purely intra-articular calluses due to failure of the primary reduction, both measured less than 2 mm. Fifteen moderate misalignements (36%) were noted, most (84.7%) involving moderate sagittal inclination, the distal radioulnar index being preserved. Two major misalignments (5%) were related to early disassembly of the osteosynthesis. Conclusion: Locked anterior plating has provided promising results for maintaining radial length in distal radial fractures with major metaphyseal comminution. There remains a certain number of cases with a moderate and persistent posterior inclination and a few cases of defective intra-articular reduction

Purpose: Cage fusion of the L5–S1 segment is a controversial issue due to the weak stabilisation of the spine during extension and axial rotation. Complementary fixation appears to be needed to improve stability, but the presence of the bifurcation of the great vessels is an anatomic limitation. We studied the anatomy of this area to examine the feasibility of anterior plate fixation. Material and methods: According to the recognised anatomic references (Rouvière, Bouchet and Cuilleret, Louis), a 33-mm safety zone was described at the aortoiliac and iliocaval bifurcation. This space free from contact with the greater vessels lies in front of the L5–S1 disc. Pre-operative angio-MRI was used to assess the size of this safety zone. A triangular anterior plate was designed for arthrodesis (Pyramid Sofamor Danek, USA). An L5–S1 arthrodesis was performed in 15 consecutive patients using this plate. Follow-up was one year. A video-assisted anterior retroperitoneal approach was used in all cases. The Prolo and Oswestry scores were used for the preoperative and last follow-up evaluations. Results: According to the anatomic study and the MRI views, 89% of the patients had a sufficient safety zone for plate fixation. The method was contraindicated in two patients who had a low bifurcation. Angio-MRI was found to be simple and reproducible. The MRI analysis was confirmed at surgery (no false negatives). The plate was successfully implanted in 15 patients with no contact with the great vessels. There were no serious complications (vascular, neurological, urological, digestive). The economic Prolo score was improved from 2.7 to 4.2 and the functional score from 2.6 to 4.3. The Oswestry score improved 33%. The rate of clinical success was 93% (14/15 patients). Discussion and conclusion: Implantation of an anterior plate for L5-S1 fusion is feasible. The key points are: 1) rigorous preoperative evaluation of the greater vessel bifurcation; 2) anatomic plate design; 3) appropriate surgical technique. The risk of retrograde ejaculation is related to retraction of the hypogastric plexus and should be investigated with a prospective study. This osteosynthesis technique can avoid secondary operations for fixation with pedicular or transarticular screwing

The ITS volar radial plate (Implant Technology Systems, Graz/Austria) is a fixation device that allows for the distal locking screws to be fixed at variable angles (70°-110°). This occurs by the different material properties, with the screws (titanium alloy) cutting a thread through the plate holes (titanium). We present our experience with the ITS plate. We retrospectively studied 26 patients who underwent ITS plate fixation for unstable multifragmentary distal radial fractures (AO types A3, B2, B3, C2, C3). The surgery was performed either by a consultant orthopaedic hand surgeon or senior registrar. A volar approach was used every time and 10 cases required synthetic bone grafting. Post-operatively they were immobilised for an average of 2.5 weeks. The 26 patients had a mean age of 58 and the dominant side was affected in 46% of cases. 5 cases were open fractures and 10 cases followed failed manipulation under general anaesthesia. The average interval between injury and surgery was 7 days. Union was achieved in all cases. No implant infections, failure or tendon rupture/irritation occurred. There were two fractures which loss reduction, of which one required revision surgery. There was one case of CRPS. The six month average DASH score was 27.5. We consider the ITS plate a technically easy plate to use and a reliable implant at early follow-up. We value the versatility of its variable angle screw fixation ability for complex intra-articular distal radial fractures

Introduction

The condition of the soft tissues surrounding an ankle fracture influences timing and treatment of injuries. Conventional treatment used an open approach to facilitate anatomical reduction and rigid internal fixation. Intramedullary devices for fibular fractures provide a safe alternative in patients in which the condition of the soft tissue envelope or the patient's co-morbidities may benefit from a less invasive approach. We compared outcomes for patients treated with open reduction internal fixation (ORIF) with those undergoing treatment with fibular nails (FN)

The aim of this study is to compare functional, clinical and radiological outcomes in K-wire fixation versus volar fixed-angle plate fixation in unstable, dorsally angulated distal radius fractures. Fifty-four adult patients with an isolated closed, unilateral, unstable, distal radius fracture were recruited to participate in the study. Only dorsally displaced fractures with no articular comminution were included. Patients were randomised to have their fracture treated with either closed reduction and K-wire fixation (3 wires) or fixed-angle volar plating. Both groups were immobilised in a below elbow cast for six weeks. The wires removed in the outpatients at six weeks and both groups were referred for physiotherapy. Independent clinical review was performed at three and six months post injury. Functional scoring was performed using the DASH and Gartland and Werley scoring systems. Radiographs were evaluated by an independent orthopaedic surgeon. Twenty-five patients were treated with a plate and twenty-nine with wires. There were no complications in the plate group. There were 9 complications in the K-wire group with 3 patients requiring a second operation (1 corrective osteotomy for malunion, 1 median nerve decompression and 1 retrieval of a migrated wire). The remaining complications included: 5 pin site infections (3 treated with early pin removal and 2 with oral antibiotics only), and 1 superficial radial nerve palsy. There were no tendon ruptures. Both groups scored satisfactory functional results with no statistical difference. There was a statistically significant difference in the radiological outcomes with the plate group achieving better results. We conclude that in unstable dorsally angulated distal radius fractures volar fixed-angle plate fixation is able to achieve comparable functional results to K-wire fixation with better radiological results and fewer complications. This has resulted in a change in our clinical practice

Biological reconstruction techniques after diaphyseal tumour resection have increased in popularity in recent years. High complication and failure rates have been reported with intercalary allografts, with recent studies questioning their role in limb-salvage surgery. We developed a technique in which large segment allografts are augmented with intramedullary cement and fixed using compression plating. The goal of this study was to evaluate the survivorship, complications and functional outcomes of these intercalary reconstructions. Forty-two patients who had reconstruction with an intercalary allograft following tumour resection between 1989 and 2010 were identified from our prospectively collected database. Allograft survival, local recurrence-free, disease-free and overall survival were assessed using the Kaplan-Meier method. Patient function was assessed using the Musculoskeletal Tumour Society (MSTS) scoring system and the Toronto Extremity Salvage Score (TESS). The 23 women and 19 men had a mean age of 33 years (14–77). The most common diagnoses were osteosarcoma (n=16) and chondrosarcoma (n=9). There were 9 humerus, 18 femur and 15 tibia reconstructions. At a mean follow-up of 95 months (5–288), 31 patients were alive without disease, 10 were dead of disease and 1 was deceased of other causes. There were 4 local recurrences and 11 patients developed metastatic disease. 5-year local recurrence free survival was 92%, 5-year disease-free survival was 70% and overall survival was 75%. Fourteen of 42 patients (33%) experienced complications: 5 wound healing complications, 4 infections, 2 non-unions, 2 fractures and 1 nerve palsy. Four allografts (9.5%) were revised for complications and 2 (5%) for local recurrence. Mean allograft survival was 85 months (4–288). Mean time to union was 8.2 (3–36) months for the proximal osteotomy site and 8.1 (3–23) months for the distal osteotomy site. The mean score for MSTS 87 was 29.4 (+/− 4.4), MSTS 93 was 83.7 (+/−14.8) and TESS was 81.6 (+/−16.9). An intercalary allograft augmented with intramedullary cement and compression plate fixation provides a reliable and durable method of reconstruction after tumour resection. Complication rates are comparable to the literature and are associated with high levels of patient function and satisfaction

Purpose: We report our expeience with the medial and posteromedial approach to the humerus for plate fixation of fractures of the distal two-thirds of the humerus. Material: Fifteen patients (eleven men and four women) were treated for fractures (n=13) or nonunion (n=2) situated below the proximal third of the humerus without radial nerve involvement. Methods: Eight patients were installed in the supine position for median approach between the humerus bundle and the median nerve anteriorly and the ulnar nerve posteriorly. The posteriomedian approach, with the ulnar nerve posteriorly and the brachial triceps anteriorly, was used for seven other patients installed in the prone position. The fixation plate applied to the medial aspect allowed at least six corticals on either side of the fracture line. The patients were immobilised for 45 days. Passive rehabilitation exercises involved the elbow and the shoulder without external rotation. Clinical and x-ray follow-up data were available for all patients. Results: One patient was lost to follow-up two months after surgery: at this time the x-ray had demonstrated bone healing. Function could not be assessed as the fracture had occurred on the same side as the hemiplegia also caused by the initial trauma. For the fourteen other patients, mean follow-up was 12 months (range 6 – 36). Three patients operated via the median approach presented paraesthesia in the median nerve territory which was regressive in two. There were no neurological complications in the posteromedian approach group. Function was good for elbow and shoulder except for two patients. Bone healing was achieved in all cases. Discussion: These approaches allowed avoiding dissection of the radial nerve and provided a more aesthetic scar. Several difficulties were encountered with the median approach and reduction was difficult to control. In such cases it is advisable to widen the exposure to avoid stretching the median nerve. These approaches are contraindicated if radial nerve injury is identified preoperatively. Conclusion: Osteosynthesis of the humerus via a median approach avoids the need for radial nerve dissection. Reduction appears to be easier via the posteromedian approach with less risk than with the median approach
