Abstract. Introduction. A lipohaemarthrosis seen on Horizontal beam lateral X-ray in acute knee injury is often considered predictive of an intra-articular fracture requiring further urgent imaging. Methodology. We retrospectively searched a five-year X-ray database for the term “lipohaemarthrosis”. We excluded cases if the report concluded “no lipohaemarthrosis” or “lipohaemarthrosis” AND “fracture”. All remaining cases were reviewed by an Orthopaedic Consultant with a special interest in knee injuries (AD) blinded to the report. X-rays were excluded if a fracture was seen, established osteoarthritic change was present, a pre-existing arthroplasty present or no lipohaemarthrosis present. Remaining cases were then studied for any subsequent Radiological or Orthopaedic surgical procedures. Results. 136 cases were identified and reviewed by an Orthopaedic Consultant. 31 were excluded for no lipohaemarthrosis (n= 11), for degenerative change (n=9), for fracture (n=4), for existing arthroplasty (n=4) and for data errors (n=3). The remaining 105 patients had a mean age of 32, and range 5–90 years. 66 patients underwent further imaging in the form of MRI scan (n=47), CT Scan (n=9) repeat x-rays (n=9) and ultrasound (n=1). 27 fractures were identified. Surgery was performed in 12 cases (11%). Two (2%) urgently (One ACL reconstruction plus meniscus repair, one for ORIF of tibial plateau fracture). Ten (10%) had elective surgery (6 for ACL reconstruction, 2 for ACL reconstruction plus meniscus repair, 2 for loose body removal. Conclusion. The presence of a lipohaemarthrosis on x-ray following acute knee injury was a poor predictor of intra-articular fracture (26%) or need for urgent surgery (2%)

We carried out a retrospective review of 47 intra-articular fractures of the calcaneum treated by open reduction and internal fixation in 45 patients by a single surgeon between 1993 and 2001. The fractures were evaluated before operation by plain radiographs and a CT scan using Sanders’ classification. Osteosynthesis involved a lateral approach and the use of the AO calcaneal plate. The mean follow-up was for ten years (7 to 15). Clinical assessment included the American Orthopaedic Foot and Ankle Society Score (AOFAS), the Creighton-Nebraska Score, the Kerr, Prothero, Atkins Score and the SF-36 Health Questionnaire. The radiological evaluation consisted of lateral and axial views of the os calcis. Arthritic changes in the subtalar joint were assessed with an internal oblique view and were graded using the Morrey and Wiedeman scale. There were 18 excellent (38.3%), 17 good (36.2%), three fair (6.3%) and nine poor (19.2%) results. Five patients had a superficial wound infection and five others eventually had a subtalar arthrodesis because of continuing pain. Restoration of Böhler’s angle was associated with a better outcome. The degree of arthritic change in the subtalar joint did not correlate with the outcome scores or Sanders’ classification. Prompt osteosynthesis should be considered for intra-articular fractures of the calcaneum in order to restore the shape of the hindfoot and Böhler’s angle

We describe the results of 287 intra-articular fractures of the calcaneum in 247 patients treated by minimally-invasive reduction and K-wire fixation between 1994 and 2003. There were 210 men (85%) and 37 women (15%). The most common cause of injury was a fall from a height in 237 patients (96%). Fracture classification was based on the method described by Sanders and Essex-Lopresti. All patients were operated on within 21 days of injury and 89% (220) within 48 hours. The reduction was graded as nearly anatomical (less than 2 mm residual articular displacement and satisfactory overall alignment) in 212 (73.9%) fractures. There were 20 cases (7%) of superficial pin-track infection and five (1.7%) of deep infection. All healed at a mean of 6 weeks (3 to 19). Loss of reduction was observed in 13 fractures (4.5%) and a musculocutaneous flap was needed in three (1%). The results were evaluated in 176 patients (205 fractures) with a mean age of 44.3 years (13 to 67), available for follow-up at a mean of 43.4 months (25 to 87) using the Creighton-Nebraska Health Foundation Assessment score. The mean score was 83.9 points (63 to 100). There were 29 (16.5%) excellent, 98 (55.7%) good, 26 (14.8%) fair and 23 (13%) poor results. A total of 130 patients (73.9%) were able to return to their original occupation at a mean of 5.6 months (3.2 to 12.5) after the injury. Semi-open reduction and percutaneous fixation is an effective treatment for displaced intra-articular fractures of the calcaneum

Aims. We report the long-term outcomes of the UK Heel Fracture Trial (HeFT), a pragmatic, multicentre, two-arm, assessor-blinded, randomized controlled trial. Methods. HeFT recruited 151 patients aged over 16 years with closed displaced, intra-articular fractures of the calcaneus. Patients with significant deformity causing fibular impingement, peripheral vascular disease, or other significant limb injuries were excluded. Participants were randomly allocated to open reduction and internal fixation (ORIF) or nonoperative treatment. We report Kerr-Atkins scores, self-reported difficulty walking and fitting shoes, and additional surgical procedures at 36, 48, and 60 months. Results. Overall, 60-month outcome data were available for 118 patients (78%; 52 ORIF, 66 nonoperative). After 60 months, mean Kerr-Atkins scores were 79.2 (SD 21.5) for ORIF and 76.4 (SD 22.5) for nonoperative. Mixed effects regression analysis gave an estimated effect size of -0.14 points (95% confidence interval -8.87 to 8.59; p = 0.975) in favour of ORIF. There were no between group differences in difficulty walking (p = 0.175), or on the type of shoes worn (p = 0.432) at 60 months. Additional surgical procedures were conducted on ten participants allocated ORIF, compared to four in the nonoperative group (p = 0.043). Conclusion. ORIF of displaced intra-articular calcaneal fractures, not causing fibular impingement, showed no difference in outcomes at 60 months compared to nonoperative treatment, but with an increased risk of additional surgery.

In a randomised prospective study, 20 patients with intra-articular fractures of the distal radius underwent arthroscopically- and fluoroscopically-assisted reduction and external fixation plus percutaneous pinning. Another group of 20 patients with the same fracture characteristics underwent fluoroscopically-assisted reduction alone and external fixation plus percutaneous pinning. The patients were evaluated clinically and radiologically at follow-up of 24 months. The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and modified Mayo wrist score were used at 3, 9, 12 and 24 months postoperatively. In the arthroscopically- and fluoroscopically-assisted group, triangular fibrocartilage complex tears were found in 12 patients (60%), complete or incomplete scapholunate ligament tears in nine (45%), and lunotriquetral ligament tears in four (20%). They were treated either arthroscopically or by open operation. Patients who underwent arthroscopically- and fluoroscopically-assisted treatment had significantly better supination, extension and flexion at all time points than those who had fluoroscopically-assisted surgery. The mean DASH scores were similar for both groups at 24 months, whereas the difference in the mean modified Mayo wrist scores remained statistically significant. Although the groups are small, it is clear that the addition of arthroscopy to the fluoroscopically-assisted treatment of intra-articular distal radius fractures improves the outcome. Better treatment of associated intra-articular injuries might also have been a reason for the improved outcome

Introduction: The magnitude of the initial chondral injury and the residual articular step-off are amongst prognostic factors implicated in outcome following intra-articular fractures. The alignment of an intra-articular fracture line may be an as yet unrecognised prognostic variable. Hypothesis: That fractures in the coronal plane of the medial femoral condyle result in worse outcomes than those in the sagittal plane. Aim: To compare the effect of displaced intra-articular osteotomies (ie simulating fractures fixed in an incongruent position) of the medial femoral condyle – in one group performed in the sagittal plane, in the other in the coronal plane. Materials and Methods: The study was conducted in two arms: in vitro and in vivo. In vitro study: A pneumo-electric rig was designed and built. Ten freshly harvested porcine knee joints underwent osteotomy (test specimens: 5 sagittal, 5 coronal). 5 control specimens underwent no osteotomy. Specimens were mounted on the rig and subjected to cyclical flexion and extension under load (40,000 cycles over 11 hours). Transarticular pressure measurements were performed before and after testing. Surface roughness was measured following testing using laser interferometry. In vivo study: Three groups (A to C), each comprising 15 New Zealand white rabbits were utilised. Rabbits from each group were consigned to a control (5), coronal osteotomy (5) or sagittal osteotomy (5) group. Rabbits in group A were sacrificed at 3 weeks (early outcome), group B at 10 weeks (immediate) and group C at 20 weeks (long term). The knee was then harvested en bloc and prepared for light microscopy. A further 10 specimens underwent electron microscopy of the medial meniscus. Results:. In vitro study: A significant difference in loading patterns was noted between the sagittal, coronal and control groups. Specimens from the sagittal group sustained significantly more wear on the apposing medial tibial articular surface (p=0.04), with the meniscus having a protective effect on the underlying articular surface. In vivo study: Light microscopy confirmed degenerative changes in the apposing tibial articular cartilage, being more marked in sagittal specimens. On the femoral side of the knee, the healing response of the femoral osteotomy was significantly better in sagittal test specimens than coronal (p< 0.05). Conclusion: In contrast to the hypothesis, sagittal femoral step-offs gave rise to more tibial wear. This can be explained by the short duration of exposure of the coronal incongruity to the apposing joint during the flexion extension cycle. The sagittal step-off was constantly exposed, giving rise to persistently elevated tibial joint loading pressures opposite the high side of the step-off. In contrast, the coronal femoral osteotomies had a worse healing response. The alignment of the fracture line perpendicular to the plane of motion of the joint exposes the repair tissue within it to increased shear and tensile stresses. This may play a negative role in the repair of these coronal defects when compared to sagittal osteotomies, which are relatively protected from the high transarticular pressures and showed a greater tendency to remodel their articular surface

Since 1986, we have treated displaced intra-articular fractures of the calcaneum by open reduction through a lateral approach, stable internal fixation and bone grafting. We assessed the results at a mean follow-up of 2.92 years in 44 patients, comparing them with those for 19 patients treated non-operatively. Clinical assessment used the scoring system of Crosby and Fitzgibbons (1990) and radiological measurements were made from lateral, axial and internal oblique views. The articular congruity of the subtalar joint and any arthritic changes were also assessed. We found significantly better results in the operated group with respect to pain, activity, range of movement, return to work and swelling of the hind foot. Radiologically, the operated group showed significantly better scores for articular congruity and arthritic changes. We conclude that the operative treatment of displaced intra-articular fractures of the calcaneum gives better medium-term results than conservative management

The extended lateral L-shaped approach for the treatment of displaced intra-articular fractures of the calcaneum may be complicated by wound infection, haematoma, dehiscence and injury to the sural nerve. In an effort to reduce the risk of problems with wound healing a technique was developed that combined open reduction and fixation of the joint fragments and of the anterior process with percutaneous reduction and screw fixation of the tuberosity. A group of 24 patients with unilateral isolated closed Sanders type II and III fractures was treated using this technique and compared to a similar group of 26 patients managed by the extended approach and lateral plating. The operation was significantly shorter (p < 0.001) in the first group, but more minor secondary procedures and removal of heel screws were necessary. There were no wound complications in this group, whereas four minor complications occurred in the second group. The accuracy and maintenance of reduction, and ultimate function were equivalent

In a prospective study of 132 patients with an average age of 35 years, unstable intra-articular fractures of the distal radius were treated by external fixator. Only 15 cases required limited open reduction. Follow-up was for a mean of 42 months. There were few complications and 83% of patients had good or excellent results. There was a statistically significant correlation between the severity of the fracture and the clinical outcome, irrespective of radiological restoration. Articular and soft-tissue damage following violent compressive forces may lead to a degree of functional impairment

We treated 31 intra-articular fractures of the distal radius by arthroscopically-assisted reduction and percutaneous fixation with Kirschner (K-) wires. Tears of the triangular fibrocartilage (58%), scapholunate (85%) and lunotriquetral (61%) instability and osteochondral lesions (19%) were also treated. A total of 26 patients was independently reviewed at an average of 19 months. The mean pain score was 1.3/10, the range of movement 79% and the grip strength 90% of the contralateral wrist. Using the New York Orthopaedic Hospital score, 88% were graded excellent to good. On follow-up radiographs, 65% had no step and 31% had a step of ≤1 mm. Pain was significantly related to the size of the step. There was a significant difference in the incidence of persistent scapholunate diastasis and the Leibovic and Geissler grade (p < 0.01): I (0%), II (0%), III (42%) and IV (100%). We recommend anatomical reduction and acceptance of a step of < 1 mm since the size of the step is related to the incidence of pain

We describe a patient who sustained a displaced isolated intra-articular fracture of the distal ulna, causing limitation of rotation of the forearm. The extent of displacement of the fracture which was not evident on plain radiographs was revealed by CT. The fracture was reduced and internally fixed using a standard technique applicable to the fixation of fractures of the radial head. Full movement was restored. An isolated injury to the distal ulna is rare and requires careful clinical and radiological assessment

Aims. Complex joint fractures of the lower extremity are often accompanied by soft-tissue swelling and are associated with prolonged hospitalization and soft-tissue complications. The aim of the study was to evaluate the effect of vascular impulse technology (VIT) on soft-tissue conditioning in comparison with conventional elevation. Methods. A total of 100 patients were included in this prospective, randomized, controlled monocentre study allocated to the three subgroups of dislocated ankle fracture (n = 40), pilon fracture (n = 20), and intra-articular calcaneal fracture (n = 40). Patients were randomized to the two study groups in a 1:1 ratio. The effectiveness of VIT (intervention) compared with elevation (control) was analyzed separately for the whole study population and for the three subgroups. The primary endpoint was the time from admission until operability (in days). Results. The mean length of time until operability was 8.2 days (SD 3.0) in the intervention group and 10.2 days (SD 3.7) in the control group across all three fractures groups combined (p = 0.004). An analysis of the subgroups revealed that a significant reduction in the time to operability was achieved in two of the three: with 8.6 days (SD 2.2) versus 10.6 days (SD 3.6) in ankle fractures (p = 0.043), 9.8 days (SD 4.1) versus 12.5 days (SD 5.1) in pilon fractures (p = 0.205), and 7.0 days (SD 2.6) versus 8.4 days (SD 1.5) in calcaneal fractures (p = 0.043). A lower length of stay (p = 0.007), a reduction in pain (p. preop. = 0.05; p. discharge. < 0.001) and need for narcotics (p. preop. = 0.064; p. postop. = 0.072), an increased reduction in swelling (p < 0.001), and a lower revision rate (p = 0.044) could also be seen, and a trend towards fewer complications (p = 0.216) became apparent. Conclusion. Compared with elevation, VIT results in a significant reduction in the time to achieve operability in complex joint fractures of the lower limb.

We reviewed 31 of 33 consecutive patients with intra-articular fractures of the knee at 6 to 22 years (average 14). Of these, 77% had excellent or good results; the others had various degrees of degenerative osteoarthritis. There was no significant difference between the results after surgical or conservative treatment. Secondary degeneration was not related to cause or type of fracture, but its incidence increased with the patient's age at the time of injury, though not with the length of follow-up. Early mobilisation appeared to be beneficial in preventing later degenerative changes

We have studied the radiographic and CT features of 120 displaced intra-articular fractures of the calcaneum in order to define the pathological anatomy. In 96% of cases, the CT scans identified three main fragments: sustentacular, lateral joint and body. The sustentacular fragment was often rotated into varus, the lateral joint fragment into valgus and the body fragment impacted upwards, in varus and displaced laterally. The displacement of these fragments varied according to which of three fracture types was present, as defined by the composition of the fractured lateral wall of the calcaneum. In type 1 it was formed by the lateral joint fragment alone; in type 2 by both body and lateral joint fragments; and in type 3 by the body fragment alone. Fracture fragment displacement differs from that previously described, in that true uniform depression of the lateral joint fragment is rare

A total of 179 adult patients with displaced intra-articular fractures of the distal radius was randomised to receive indirect percutaneous reduction and external fixation (n = 88) or open reduction and internal fixation (n = 91). Patients were followed up for two years. During the first year the upper limb musculoskeletal function assessment score, the SF-36 bodily pain sub-scale score, the overall Jebsen score, pinch strength and grip strength improved significantly in all patients. There was no statistically significant difference in the radiological restoration of anatomical features or the range of movement between the groups. During the period of two years, patients who underwent indirect reduction and percutaneous fixation had a more rapid return of function and a better functional outcome than those who underwent open reduction and internal fixation, provided that the intra-articular step and gap deformity were minimised

We describe the surgical technique and results of arthroscopic subtalar release in 17 patients (17 feet) with painful subtalar stiffness following an intra-articular calcaneal fracture of Sanders’ type II or III. The mean duration from injury to arthroscopic release was 11.3 months (6.4 to 36) and the mean follow-up after release was 16.8 months (12 to 25). The patient was positioned laterally and three arthroscopic portals were placed anterolaterally, centrally and posterolaterally. The sinus tarsi and lateral gutter were debrided of fibrous tissue and the posterior talocalcaneal facet was released. In all, six patients were very satisfied, eight were satisfied and three were dissatisfied with their results. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved from a mean of 49.4 points (35 to 66) pre-operatively to a mean of 79.6 points (51 to 95). All patients reported improvement in movement of the subtalar joint. No complications occurred following operation, but two patients subsequently required subtalar arthrodesis for continuing pain. In the majority of patients a functional improvement in hindfoot function was obtained following arthroscopic release of the subtalar joint for stiffness and pain secondary to Sanders type II and III fractures of the calcaneum

The classification of intra-articular fractures of the calcaneum described in part I is related to an operative approach which allows accurate reduction and stable fixation of the fracture fragments. An extended lateral incision is used to avoid sural nerve damage and problems of soft-tissue healing. In type 3 fractures, access to the lateral joint fragment requires an osteotomy of the lateral wall, but after this the lateral joint fragment can be rotated out of the subtalar joint to allow transcalcaneal reduction of the medial wall. Reduction of the body fragment and lateral joint fragment on to the sustentacular fragment allows the three fragments to be stabilised by a 3.5 mm Y-shaped reconstruction plate. Our early results have been successful in terms of fracture reduction and the restoration of heel shape and joint congruity, but extended follow-up will be necessary to define the indications for this difficult procedure

Aims. Management of intra-articular calcaneal fractures remains a debated topic in orthopaedics, with operative fixation often held in reserve due to concerns regarding perioperative morbidity and potential complications. The purpose of this study was to identify the characteristics of patients who developed surgical complications to inform the future stratification of patients best suited to operative treatment for intra-articular calcaneal fractures and those in whom surgery was highly likely to produce an equivocal functional outcome with potential post-operative complications. Methods. All patients who underwent open reduction and internal fixation of calcaneal fractures utilizing the Sinus Tarsi approach between March 2014 and July 2018 were identified using theatre records. Patient imaging was used to assess pre- and post-operative fracture geometry with Computed Tomography (CT) used for pre-operative planning. Each patient's clinical presentation was established through retrospective analysis of medical records. Patients provided verbal consent to participation and patient reported outcome measures were recorded using the Maryland Foot Score. Results. Fifty-eight intra-articular calcaneal fractures (fifty-three patients including five bilateral, mean age = 46.91 years) were included. Forty-nine patients were injured as a result of a fall from a height (92.4%). Mean time from presentation to surgery was 3.23 days (range 0–21). Mean Maryland Foot score was found to be 77.6 (+/− 16.22) in forty-five patients. Five patients (9.4%) had wound complications; two superficial (3.7%) and three deep (5.6%). Conclusion. Intra-articular fractures of the calcaneus should be considered for surgical intervention in order to improve long-term functional outcomes. The Sinus Tarsi approach provides the potential to decrease the operative complication rate whilst maintaining adequate fixation, however, the decision to surgically manage these fractures should be carefully balanced against the risk of post-operative complications. This increased risk of complication associated with smoking may tip the balance against benefit from surgical management

We retrospectively reviewed 60 fractures of the tibial plafond treated by either an ankle-sparing diaphyseal-epiphyseal technique using the Ilizarov ring fixator or by an ankle-spanning technique using a monolateral articulated external fixator. The Ilizarov ring fixator was applied in 24 fractures and the monolateral articulated transarticular external fixator in 20. Both techniques were combined with limited open reduction and internal fixation of the articular surface if necessary. Between three and nine years after the injury, all patients returned for clinical and radiological assessment and evaluation of ankle function using the modified Mazur score. There were no significant differences between the two groups in terms of age, gender, mechanism of injury, type of fracture or length of follow-up.

The mean functional ankle score was 86 points for the Ilizarov group and 82 points for the articulated fixator group. The difference was not significant (p = 0.07). There were no significant differences between the groups with regard to the radiographic score and late complications. Patients treated with the Ilizarov ring fixator had significantly better ankle and subtalar movement.

We conclude that both techniques of external fixation are satisfactory methods of treatment for fractures of the tibial plafond, but that the total arc of movement of the joint is preserved better without bridging the ankle.

A minimally-invasive procedure using percutaneous reduction and external fixation can be carried out for Sanders’ type II, III and IV fractures of the os calcis. We have treated 54 consecutive closed displaced fractures of the calcaneum involving the articular surface in 52 patients with the Orthofix Calcaneal Mini-Fixator. Patients were followed up for a mean of 49 months (27 to 94) and assessed clinically with the Maryland Foot Score and radiologically with radiographs and CT scans, evaluated according to the Score Analysis of Verona. The clinical results at follow-up were excellent or good in 49 cases (90.7%), fair in two (3.7%) and poor in three (5.6%). The mean pre-operative Böhler’s angle was 6.98° (5.95° to 19.86°), whereas after surgery the mean value was 21.94° (12.58° to 31.30°) (p < 0.01). Excellent results on CT scanning were demonstrated in 24 cases (44.4%), good in 25 (46.3%), fair in three (5.6%) and poor in two (3.7%). Transient local osteoporosis was observed in ten patients (18.5%), superficial pin track infection in three (5.6%), and three patients (5.6%) showed thalamic displacement following unadvised early weight-bearing.

The clinical results appear to be comparable with those obtainable with open reduction and internal fixation, with the advantages of reduced risk using a minimally-invasive technique.

We report a prospective trial of 66 patients with intraarticular fractures of the calcaneum. All fractures were assessed by CT. Patients with displaced fractures were randomised to receive either conservative (n = 31) or operative treatment (n = 25). Undisplaced fractures (n = 10) were treated conservatively. Operation involved open reduction of the posterior subtalar joint, and fixation with Kirschner wires. All 66 patients were reviewed at a minimum of one year (mean 23 months). After conservative treatment the undisplaced fractures had slightly better results than the displaced fractures. There was no significant difference in outcome between the operatively and the conservatively treated displaced fractures. We have also documented prospectively the natural history of the injury, which is of use in assessing prognosis for both clinical and medicolegal purposes.

Background: Closed reduction of intra-articular calcaneal fractures sometimes lack the accuracy desired for restoring the normal anatomy of the articular surface of the calcaneus. In this study, we evaluate the preliminary results of closed reduction of the intra-articular calcaneal fractures with an Ilizarov frame. Patients and Method: Forty patients (25 males and 15 females) with 50 intra-articular fracture calcaneal fractures were treated with closed reduction and an Ilizarov frame. The mean age was 25.4 years (range from 19 to 65). Union was achieved after two months. The results were evaluated on the basis of combined clinical and radiological examination at the latest follow-up. Results were classified according to the protocol and scoring system used by Paley and Hall 1993. Results: The mean follow up period was 1.9 years (range 6 months to 4 years). At final follow up there were 15 excellent feet, 26 were good, 6 fair and 3 poor. The mean Bohler angle postoperatively was 260 (range 17 to 35). Superficial infection occurred in seven feet and was controlled. Skin pressure necrosis of the posterior aspect of the heel occurred in three feet. One needed a skin graft. Conclusion: This method is a minimally invasive technique. The technique has the ability to restore the normal anatomy, shape and length of the calcaneal body, especially in Sander’s type III and type IV fractures. It is particularly useful for osteoprotic bone as it provides rigid fixation

We reviewed the results of 13 adults of secondary reconstruction of malunited and ununited intraarticular distal humeral fractures. Their average age was 39.7 years, and preoperatively all had pain, loss of motion and functional disability; the average arc of motion was only 43 degrees and the average flexion contracture was 45 degrees. Nine patients had ulnar neuropathy. Elbow reconstruction, at an average of 13.4 months after the original injury, included osteotomy for malunion or debridement for nonunion, realignment with stable fixation and autogenous bone grafts, anterior and posterior capsulectomy and ulnar neurolysis. The elbows were mobilised 24 hours postoperatively. There were no early complications and all nonunions and intra-articular osteotomies healed. After a mean follow-up of 25 months, the average arc of motion was 97 degrees with no progressive radiographic degeneration. Ulnar nerve function improved in all cases and clinical assessment using the Morrey score showed two excellent, eight good and three fair results. Reconstruction of intra-articular malunion and nonunion of the distal humerus in young active adults is technically challenging, but can improve function by restoring the intrinsic anatomy of the elbow.

Background. Optimal management of displaced intra-articular calcaneal fractures remains controversial. The aim of this prospective cohort study was to compare the clinical and radiological outcomes of minimally invasive surgery (MIS) versus non-operative treatment in displaced intra-articular calcaneal fracture up to 2-years. Methods. All displaced intra-articular calcaneal fractures between August 2014 and January 2019 that presented to a level 1 trauma centre were considered for inclusion. The decision to treat was made by a multidisciplinary meeting. Operative treatment protocol involved sinus tarsi approach or percutaneous reduction & internal fixation. Non-operative protocol involved symptomatic management with no attempt at closed reduction. All fractures were classified, and the MOXFQ/EQ-5D-5L scores were used to assess foot and ankle and general health-related quality of life outcomes respectively. Results. 101 patients were recruited at a level 1 major trauma centre, between August 2014 and January 2019. Our propensity score matched 44 patients in the surgical cohort to 44 patients in the non-surgical cohort. At 24 months, there was no significant difference in the MOXFQ Index score (p<0.05) however the patients in the surgical cohort had a significantly higher EQ-5D-5L Index score (p<0.05). There was also a higher return to work (91% vs 72%, p<0.05) and physical activity rate (46 vs. 35%, p<0.05) in the surgical cohort despite a higher proportion of more complex fractures in the surgical cohort. The wound complication rate following surgery was 16%. 14% of patients in the non-operative cohort subsequently underwent arthrodesis compared to none of the patients in the surgical cohort. Conclusion. In this study, we found operative treatments were associated with low rates of surgical complication at 2-years and long term pain improvement, facilitating earlier and better functional outcomes for complex injury patterns compared to nonoperative treatment

Distal radius fractures (DRFs) are one of the most common types of fracture and one which is often treated surgically. Standard X-rays are obtained for DRFs, and in most cases that have an intra-articular component, a routine CT is also performed. However, it is estimated that CT is only required in 20% of cases and therefore routine CT's results in the overutilisation of resources burdening radiology and emergency departments. In this study, we explore the feasibility of using deep learning to differentiate intra- and extra-articular DRFs automatically and help streamline which fractures require a CT. Retrospectively x-ray images were retrieved from 615 DRF patients who were treated with an ORIF at the Royal Brisbane and Women's Hospital. The images were classified into AO Type A, B or C fractures by three training registrars supervised by a consultant. Deep learning was utilised in a two-stage process: 1) localise and focus the region of interest around the wrist using the YOLOv5 object detection network and 2) classify the fracture using a EfficientNet-B3 network to differentiate intra- and extra-articular fractures. The distal radius region of interest (ROI) detection stage using the ensemble model of YOLO networks detected all ROIs on the test set with no false positives. The average intersection over union between the YOLO detections and the ROI ground truth was Error! Digit expected.. The DRF classification stage using the EfficientNet-B3 ensemble achieved an area under the receiver operating characteristic curve of 0.82 for differentiating intra-articular fractures. The proposed DRF classification framework using ensemble models of YOLO and EfficientNet achieved satisfactory performance in intra- and extra-articular fracture classification. This work demonstrates the potential in automatic fracture characterization using deep learning and can serve to streamline decision making for axial imaging helping to reduce unnecessary CT scans

Chauffeur fractures or isolated radial styloid fractures (IRSF) are known to be associated with scapholunate ligament (SL) injuries. Diagnosis without arthroscopic confirmation is difficult in acute fractures. Acute management of this injury with early repair may prevent the need for more complex reconstructive procedures for chronic injuries. We investigated if all IRSF should be assessed arthroscopically for concomitant SL injuries. We performed a prospective cohort study on patients above the age of 16, presenting to the Gold Coast University Hospital with an IRSF, over 2 years. Plain radiographs and computerized tomography (CT) scans were performed. All patients had a diagnostic wrist arthroscopy performed in addition to an internal fixation of the IRSF. Patients were followed up for at least 3 months post operatively. SL repair was performed for all Geissler Grade 3/4 injuries. 10 consecutive patients were included in the study. There was no radiographic evidence of SL injuries in all patients. SL injuries were identified arthroscopically in 60% of patients and one third of these required surgical stabilisation. There were no post operative complications associated with wrist arthroscopy. We found that SL injuries occurred in 60% of IRSF and 20% of patients require surgical stabilisation. This finding is in line with the literature where SL injuries are reported in up to 40-80% of patients. Radiographic investigations were not reliable in predicting possible SL injuries in IRSF. However, no SL injuries were identified in undisplaced IRSF. In addition to identifying SL injuries, arthroscopy also aids in assisting and confirming the reduction of these intra-articular fractures. In conclusion, we should have a high index of suspicion of SL injury in IRSF. Arthroscopic assisted fixation should be considered in all displaced IRSF. This is a safe additional procedure which may prevent missed SL injuries and their potential sequelae

Background. Anatomical reduction of unstable Lisfranc injuries is crucial. Evidence as to the best methods of surgical stabilization remains sparse, with small patient numbers a particular issue. Dorsal bridge plating offers rigid stability and joint preservation. The primary aim of this study was to assess the medium-term functional outcomes for patients treated with this technique at our centre. Additionally, we review for risk factors that influence outcomes. Methods. 85 patients who underwent open reduction and dorsal bridge plate fixation of unstable Lisfranc injuries between January 2014 and January 2019 were identified. Metalwork was not routinely removed. A retrospective review of case notes was conducted. The Manchester-Oxford Foot Questionnaire summary index (MOXFQ-Index) was the primary outcome measure, collected at final follow-up, with a minimum follow-up of 24 months. The American Orthopedic Foot and Ankle Society (AOFAS) midfoot scale, complications, and all-cause re-operation rates were secondary outcome measures. Univariate and multivariate analyses were used to identify risk factors associated with poorer outcomes. Results. Mean follow-up 40.8 months (24–72). Mean MOXFQ-Index 27.0 (SD 7.1). Mean AOFAS score 72.6 (SD 11.6). 48/85 patients had injury patterns that included an intra-articular fracture and this was associated with poorer outcomes, with worse MOXFQ and AOFAS scores (both p < 0.001). 18 patients (21%) required the removal of metalwork for either prominence or stiffness. Female patients were more likely to require metalwork removal (OR 3.89, 95% CI 1.27 to 12.0, p = 0.02). Eight patients (9%) required secondary arthrodesis. Conclusions. This is the largest series of Lisfranc injuries treated with dorsal bridge plate fixation reported to date and the only to routinely retain metalwork. The technique is safe and effective. The presence of an intraarticular fracture is a poor prognostic indicator. Metalwork removal is more likely to be needed in female patients but routine removal may not be essential

Introduction. Diaphyseal tibial fractures account for approximately 1.9% of adult fractures. Studies have demonstrated a high proportion have ipsilateral occult posterior malleolus fractures. We hypothesize that this rotational element will be highlighted using the Mason & Molloy Classification. Materials and Methods. A retrospective review of a prospectively collected database was performed at Liverpool University Hospitals NHS Foundation Trust between 1/1/2013 and 9/11/2020. The inclusion criteria were patients over 16, with a diaphyseal tibial fracture, who underwent a CT. The Mason and Molloy posterior malleolus fracture classification system was used. Results. 764 diaphyseal tibial fractures were analysed, 300 had a CT. 127 were intra-articular fractures. 83 (27.7%) were classifiable using Mason and Molloy classification. There were 8 type 1 (9.6%), 43 type 2 (51.8%), 5 type 2B (6.0%) and 27 type 3 (32.5%). 90.4% (n=75) of the posterior malleolar fractures, were undisplaced. The majority of PM fractures occurred in type 42A1 (65 of 142 tibia fractures) and 42B1 (11 of 16). Conclusions. Most PM fractures occurred after a rotational mechanism. Unlike, the PM fractures of the ankle, the majority of PM fractures associated with tibia fractures are undisplaced. We theorise that unlike the force transmission in ankle fractures where the rotational force is in the axial plane in a distal-proximal direction, in the PM fractures related to fractures of the tibia, the rotational force in the axial plane progresses from proximal-distal. Therefore, the force transmission which exits posteriorly, finally dissipates the force and thus unlikely to displace

This edition of the Cochrane Corner looks at the three reviews that were published in the second half of 2023: surgical versus non-surgical interventions for displaced intra-articular calcaneal fractures; cryotherapy following total knee arthroplasty; and physical activity and education about physical activity for chronic musculoskeletal pain in children and adolescents

Introduction. Diaphyseal tibial fractures account for approximately 1.9% of adult fractures. Several studies demonstrate a high proportion of diaphyseal tibial fractures have ipsilateral occult posterior malleolus fractures, this ranges from 22–92.3%. Materials and Methods. A retrospective review of a prospectively collected database was performed at Liverpool University Hospitals NHS Foundation Trust between 1/1/2013 and 9/11/2020. The inclusion criteria were patients over 16, with a diaphyseal tibial fracture and who underwent a CT. The articular fracture extension was categorised into either posterior malleolar (PM) or other fracture. Results. 764 fractures were analysed, 300 had a CT. There were 127 intra-articular fractures. 83 (65.4%) cases were PM and 44 were other fractures. On univariate analysis for PM fractures, fibular spiral (p=.016) fractures, no fibular fracture(p=.003), lateral direction of the tibial fracture (p=.04), female gender (p=.002), AO 42B1 (p=.033) and an increasing angle of tibial fracture. On multivariate regression analysis a high angle of tibia fracture was significant. Other fracture extensions were associated with no fibular fracture (p=.002), medial direction of tibia fracture (p=.004), female gender (p=.000), and AO 42A1 (p=.004), 42A2 (p=.029), 42B3 (p=.035) and 42C2 (p=.032). On multivariate analysis, the lateral direction of tibia fracture, and AO classification 42A1 and 42A2 were significant. Conclusions. Articular extension happened in 42.3%. A number of factors were associated with the extension, however multivariate analysis did not create a suitable prediction model. Nevertheless, rotational tibia fractures with a high angle of fracture should have further investigation with a CT

Aims. Local recurrence remains a challenging and common problem following curettage and joint-sparing surgery for giant cell tumour of bone (GCTB). We previously reported a 15% local recurrence rate at a median follow-up of 30 months in 20 patients with high-risk GCTB treated with neoadjuvant Denosumab. The aim of this study was to determine if this initial favourable outcome following the use of Denosumab was maintained with longer follow-up. Methods. Patients with GCTB of the limb considered high-risk for unsuccessful joint salvage, due to minimal periarticular and subchondral bone, large soft tissue mass, or pathological fracture, were treated with Denosumab followed by extended intralesional curettage with the goal of preserving the joint surface. Patients were followed for local recurrence, metastasis, and secondary sarcoma. Results. A total of 25 patients with a mean age of 33.8 years (18 to 67) with high-risk GCTB received median six cycles of Denosumab before surgery. Tumours occurred most commonly around the knee (17/25, 68%). The median follow-up was 57 months (interquartile range (IQR) 13 to 88). The joint was salvaged in 23 patients (92%). Two required knee arthroplasty due to intra-articular fracture and arthritis. Local recurrence developed in 11 patients (44%) at a mean of 32.5 months (3 to 75) following surgery, of whom four underwent repeat curettage and joint salvage. One patient developed secondary osteosarcoma and another benign GCT lung metastases. Conclusion. The use of Denosumab for joint salvage was associated with a higher than expected rate of local recurrence at 44%. Neoadjuvant Denosumab for joint-sparing procedures should be considered with caution in light of these results. Cite this article: Bone Joint J 2021;103-B(1):184–191

Introduction. Pilon fractures are complex, high-energy, intra-articular fractures of the distal tibia. Achieving good outcomes is challenging due to fracture complexity and extensive soft tissue damage. The purpose of this study was to determine the long-term functional and clinical outcomes of definitive management with fine wire Ilizarov fixation for closed pilon fractures. Materials and Methods. 185 patients treated over a 14-year period (2004–2018) were included. All patients had Ilizarov frames applied to restore mechanical axis and fine wires to control periarticular fragments. CT scans were performed post operatively to confirm satisfactory restoration of the articular surface. All frames were dynamized prior to removal. Patients' functional outcome was assessed using the validated Chertsey Outcome Score for Trauma (“COST”). Review of clinical notes and imaging was used to determine complications and time to union. Results. The mean functional outcome in the studied cohort was determined to be “average” on the “COST” score. Poorer functional outcomes were associated with younger age at time of injury and multi-fragment fracture patterns. Mean time in frame was 170 days. Complication rates were low. There were no deep infections, no amputations and only 8 patients went on to have ankle fusions. Conclusions. Good functional results and low complication rates can be achieved by managing pilon fractures with fine wire Ilizarov fixation. Nonetheless, at time of injury patients should be counselled as to the severity of the injury and impact on their functional status

Radial head fractures are among the most common fractures around the elbow. Radial head arthroplasty is one of the surgical treatment options after complex radial head fractures. This surgery is usually done under general anaesthesia. However, there is a recent anaesthetic technique - wide awake local anaesthesia no tourniquet (WALANT) - that has proven useful in different surgical settings, such as in distal radius or olecranon fractures. It allows a good haemostatic control without the use of a tourniquet and allows the patient to actively collaborate during the surgical procedure. Furthermore, there are no side effects or complications caused by the general anaesthesia and there's an earlier patient discharge. The authors present the case of a seventy-six-year-old woman who presented to the emergency department after a fall from standing height with direct trauma to the left elbow. The radiological examination revealed a complete intra-articular comminuted fracture of the radial head (Mason III). Clinical management: The patient was submitted to surgery with radial head arthroplasty, using WALANT. The surgery was successfully completed without pain. There were no intra or immediate post-operative complications and the patient was discharged on the same day. Six weeks after surgery, the patient had almost full range of motion and was very pleased with the functional outcome, with no limitations on her activities of daily living. The use of WALANT has been expanded beyond the hand and wrist surgery. It is a safe and simple option for patients at high risk of general anaesthesia, allowing similar surgical outcomes without the intraoperative and postoperative complications of general anaesthesia and permitting an earlier hospital discharge. Furthermore, it allows the patient to actively collaborate during the surgery, providing the surgeons the opportunity to evaluate active mobility and stability, permitting final corrections before closing the incision

Distal radius fractures (DRF) are very common injuries. National recommendations (British Orthopaedic Association, National Institute for Health and Care Excellence (NICE)) exist in the UK to guide the management of these injuries. These guidelines provide recommendations about several aspects of care including which type of injuries to treat non-operatively and surgically, timing of surgery and routine follow-up. In particular, current recommendations include considering immobilizing patients for 4 weeks in plaster for those managed conservatively, and operating on fractures within 72 hours for intra-articular injuries and 7 days for extra-articular fractures. With increased demands for services and an ageing population, prompt surgery for those presenting with distal radius fractures is not always possible. A key factor is the need for prompt surgery for hip fracture patients. This study is an audit of the current standard of care at a busy level 2 trauma unit against national guidelines for the management of DRFs. This retrospective audit includes all patients presenting to our emergency department from June to September 2018. Patients over 18 years of age with a diagnosis of a closed distal radius fracture and follow-up in our department were included in the study. Those with open fractures were excluded. Data was retrieved from clinical coding, electronic patient records, and IMPAX Client (Picture archiving and communication system). The following data was collected on patients treated conservatively and those managed surgically:- (1)Time to surgery for surgical management; (2)Period of immobilization for both conservative and operative groups. 45 patients (13 male, 32 female) with 49 distal radius fractures (2 patients had bilateral injuries) were included. Patients had mean age 63 years (range 19 to 92 years) 30 wrists were treated non-operatively and 19 wrists treated surgically (8 K-wires, 10 ORIF, 1 MUA). Mean time to surgery in the operative group was 8 days (range 1 – 21 days, median 7 days). Mean time to surgery for intra-articular fractures was 7 days (range 1 – 21) and 12 days for extra-articular fractures (range 4 – 20). Mean immobilization period in those treated in plaster is 6 weeks (range 4 – 13 weeks, median 5.6 weeks). At busy level 2 trauma units with limited theatre capacity and a high volume of hip fracture admissions, time to surgery for less urgent injuries such as wrist fractures is often delayed. National guidelines are useful in helping to guide management however their standards are often difficult to achieve in the context of increasing populations in urban areas and an ageing population

Despite the current trend favoring surgical treatment of displaced intra-articular calcaneal fractures (DIACFs), studies have not been able to demonstrate superior functional outcomes when compared to non-operative treatment. These fractures are notoriously difficult to reduce. Studies investigating surgical fixation often lack information about the quality of reduction even though it may play an important role in the success of this procedure. We wanted to establish if, amongst surgically treated DIACF, an anatomic reduction led to improved functional outcomes at 12 months. From July 2011 to December 2020, at a level I trauma center, 84 patients with an isolated DIACF scheduled for surgical fixation with plate and screws using a lateral extensile approach were enrolled in this prospective cohort study and followed over a 12-month period. Post-operative computed tomography (CT) imaging of bilateral feet was obtained to assess surgical reduction using a combination of pre-determined parameters: Böhler's angle, calcaneal height, congruence and articular step-off of the posterior facet and calcaneocuboid (CC) joint. Reduction was judged anatomic when Böhler's angle and calcaneal height were within 20% of the contralateral foot while the posterior facet and CC joint had to be congruent with a step-off less than 2 mm. Several functional scores related to foot and ankle pathology were used to evaluate functional outcomes (American Orthopedic Foot and Ankle Score - AOFAS, Lower Extremity Functional Score - LEFS, Olerud and Molander Ankle Score - OMAS, Calcaneal Functional Scoring System - CFSS, Visual Analog Scale for pain - VAS) and were compared between anatomic and nonanatomic DIAFCs using Student's t-test. Demographic data and information about injury severity were collected for each patient. Among the 84 enrolled patients, 6 were excluded while 11 were lost to follow-up. Thirty-nine patients had a nonanatomic reduction while 35 patients had an anatomic reduction (47%). Baseline characteristics were similar in both groups. When we compared the injury severity as defined by the Sanders’ Classification, we did not find a significant difference. In other words, the nonanatomic group did not have a greater proportion of complex fractures. Anatomically reduced DIACFs showed significantly superior results at 12 months for all but one scoring system (mean difference at 12 months: AOFAS 3.97, p = 0.12; LEFS 7.46, p = 0.003; OMAS 13.6, p = 0.002, CFSS 7.5, p = 0.037; VAS −1.53, p = 0.005). Univariate analyses did not show that smoking status, worker's compensation or body mass index were associated with functional outcomes. Moreover, fracture severity could not predict functional outcomes at 12 months. This study showed superior functional outcomes in patients with a DIACF when an anatomic reduction is achieved regardless of the injury severity

Aim: Evaluation of intermediate clinical and radiographic results of displaced intra-articular fractures of the calcaneus treated with ORIF. Materials- Methods: From 1994 to 2002, 167 displaced intra-articular fractures of the calcaneus were treated with ORIF. There were 145 male and 12 female patients. Mean age 34 years. Standard x-rays, Broden views and CT-scan images in coronal and transverse plane were obtained pre and post operatively. Fractures were classified as type III, IV, V according to Sanders. All fractures were approached through an extended lateral L-type approach. AO calcaneal plate was used. Average follow-up was 5 years. Results: In 143 Sanders type III and IV fractures KITA-OKA score was 91. Reduction failure rate was 5.5%(8 pts). 24 patients had Sanders type V fractures and KITAOKA score was 84 and reduction failure rate was 25% (6 pts). 29/167 patients complained of peroneal tendons tenderness which subsided after hardware removal. 79/167 patients had restriction of subtalar joint movements but no complains (SF_36) There were two superficial wound infections and five patients with delayed wound closure. In a group of 45 patients with similar fracture patterns who were treated conservatively, KITA-OKA score was 71, 41 fractures were malunited, 40 patients had moderate to severe pain and early OA sings. Conclutions: Displaced intra-articular fractures of the calcaneus should be treated as any other displaced intra-articular fracture, with open reduction and stable internal fixation

We have assessed the long-term results after operative and non-operative treatment of undisplaced and displaced calcaneal fractures. At a mean of 6.5 years, we reviewed 70 patients with a calcaneal fracture who were divided into four groups: group 1, 18 patients with undisplaced fractures and a normal Böhler’s angle (BA) who had been treated non-operatively; group 2, 23 with intra-articular fractures and a BA < 10° who had been treated non-operatively; group 3, 13 with intra-articular fractures and a BA > 10° who had been treated surgically; and group 4, 16 with intra-articular fractures and a BA < 10° who had been treated surgically. The results were assessed by a clinical score considering pain, return to work, return to physical activity, change in shoe-wear and the requirement for subtalar arthrodesis. Patients with undisplaced calcaneal fractures had a good outcome. Those with displaced fractures treated surgically who presented at follow-up with a BA > 10° had a satisfactory functional outcome and those with displaced fractures who had non-operative treatment had a poor outcome. The poorest outcome was consistently seen in patients who were treated operatively without restoration of BA. Open reduction and internal fixation of intra-articular calcaneal fractures can only be expected to benefit those patients in whom nearly anatomical reconstruction is obtained

Aim: 1. To assess the role of the CT scan in management of intra-articular fractures of the calcaneum. 2. Does the scan makes any difference to the management decision, obtained from assessing the plain radiograph?. Methodology: This study involved 24 patients with intra-articular fracture of the calcaneum who had both a plain radiograph and a CT scan as a part of their assessment. Three consultants who were blinded to the actual management and names of the subjects were independently asked to grade the radiographs and CT scans, as operative or non-operative, on different occasions. The data was matched to the actual management and was subjected to statistical analysis. Results: The data was non-parametric and related. The SIGN test was used to analyse the agreement between the three observers and if the decisions made in each of the groups were significantly different from the actual management. There was no statistically significant difference, between the management decision from the radiographs or CT and the actual management. The change in management that the CT scan brought about was also assessed for each of the observers using the McNemars test. The CT scan did not make any significant difference to the decision made based on the plain radiographs, on whether to operate or not. A Cochran Q test used to assess the variability of the decisions, showed that there was more inter-observer variability in decision making, using the CT based assessment (Q=9.50, p=0.009) as compared to plain radiographs (Q=3.84, p=0.14). Conclusion: We conclude that, the CT scan should only be requested when a decision is made to operate on the fracture, based on plain radiographs. This may help with pre-operative planning of fracture fixation. It does not have to be obtained as a routine to assess all intra-articular fractures of the calcaneum

Introduction: The treatment of comminuted intra-articular fractures around the knee is one of most difficult areas of Orthopaedic traumatology. Open reduction and internal fixation is recommended by many authors. However, in severe comminuted fractures sometime it is difficult to achieve stable fixation and most cases need an additional cast immobilization following surgery. We present our experience with arthroscopic assisted closed reduction in severe comminuted knee fractures followed by fixation with Ilizarov frame. Materials and Methods: Since 1998, 17 patients with comminuted intra-articular fractures around the knee were treated by this method. 8 patients had comminuted intra-articular fractures of the distal femur and 9 patients had comminuted fractures of the tibial plateau, one of them with fractures of both knees. There were 4 males and 4 females with femoral fractures (age: 22– 56Y; mean -31Y) and 8 males and 1 female with tibial plateau fractures (age: 34–68Y; mean – 51Y). Three fractures of the distal femur and 2 of the tibial plateau were open fractures. 5/17 Pts had polytrauma. We used AO classification for distal femoral fractures and Schatzker classification for tibial plateau fractures. All patients were operated within 48 hours after injury. Results: In all patients, except two with unstable knee, closed reduction and Ilizarov external fixation was performed without knee immobilization, under knee arthroscopic control. In two cases split thickness skin graft was done following leg fasciotomies. Weight bearing was allowed 6 to 8 weeks following surgery. A second look arthroscopy was performed in 3 cases. The average time of fixation in Ilizarov frame was 4.5 months (range 3–6.5 months). On follow up of 2 to 8 years, 6/17 patients (35%) had excellent results, 8/17 patients (47%) had good results and 3 patients (17%) had fair results. No cases of osteomyelitis, neuro-vasular injuries or deep wound infection were observed. Conclusions: Based on this study it seems that arthroscopic assisted closed reduction and Ilizarov fixation is very useful for severe intra-articular comminuted knee fractures. Arthroscopy of knee enables accurate reduction of these fractures, removal of free bone fragments and treatment of other intra-articular injuries. There is an early restoration of motion in injured knee, with short immobilization time, and there are no major complications

Background. The usefulness of arthroscopic reduction for the intra-articular fracture of the distal radius has been reported, although it is technically difficult. Hypothesis. Our hypothesis is that the reduction using the external fixator is useful as equivalent to the arthroscopic reduction for the intra-articular fracture of the distal radius fracture in the fixation with the volar locking plate. Materials & Methods. The surgery was performed in both methods randomly for 40 patients; average age 64(24 to 92) years, 11 male, 29 female. Image evaluations were performed at 24 weeks after surgery. Ulnar variance, Radial inclination, Volar tilt in the X-ray image, and gap and step in the computed tomogram were evaluated. Clinical evaluation was performed at 6, 12, 24 weeks after surgery. Objective evaluations were ranges of motion and grip strength. Subjective evaluations were disabilities of the arm, shoulder, and hand (DASH). Results. The results of image and objective evaluation had no significant difference between the two groups. DASH in arthroscopic group was significantly inferior at 24 weeks because of minor complications. Discussion & Conclusion. The external fixator and the arthroscopy are equally valuable in reduction of articular surface

Controversy exists regarding the management of intra-articular fractures of the calcaneus. We present medium-term outcome data on 37 consecutive patients who underwent open reduction and internal fixation for comminuted intra-articular calcaneal fractures. Operations were performed by one surgeon, CRW, following CT assessment of the fracture. All procedures were performed using an extensile lateral approach and early physiotherapy was standard. Case notes were reviewed retrospectively between three months and five years post-operatively. Patients were also invited to attend a follow-up clinic where outcomes were assessed using the American Orthopaedic Foot and Ankle Society Hind Foot Score and were questioned regarding on-going problems, change in shoe size and return to work. Complete data is available for 16 patients, with additional information from other patients. Results show average AOFAS scores for type II fractures to be 59/100, type III to be 81/100 and 79/100 for type IV fractures. We have shown low rates of complications – one infection, three patients requiring a change in shoe size and an average return to work of seven months. We have shown good medium-term outcome results for the operative management of displaced intra-articular fractures and to answer our question, we believe we should be operating on them

Introduction: Outcome following intra-articular fractures is dependent on a myriad of variables, including the extent of the initial osteochondral and soft tissue injury. In the clinical setting it is impossible to control such variables, and studies are largely confined to radiographic and outcome based assessments. Therefore the effect of fracture line orientation has not been widely examined. Theoretically an incongruent intra-articular fracture results in a “low” side that is relatively unloaded, at the expense of a “high” side exposed to increased loads. Furthermore the orientation of the fracture may give rise to a narrow or broad swathe of wear on the opposing articular surface. Aim: To evaluate the effect of an incongruent intra-articular fracture of the medial femoral condyle on subsequent loading and wear patterns, using an in vitro model. Materials and Methods: 15 porcine stifle (knee) joints were harvested within three hours of death. Three groups of five joints were evaluated. Group S underwent a sagittal osteotomy of the medical femoral condyle that was then fixed in an incongruent position. In Group C the osteotomy was performed in the coronal plane. The third group acted as a control group and had no oseotomy performed. In all cases great care was taken to prevent injury to the menisci, articular surfaces and Ligamentous structures. The size of the step-off was documented using a contour-mapping machine (CMN). In addition the surface roughness of the femoral condyles was documented using a laser interferometry device (UBM, Germany). The specimen was mounted on a custom-made electro-pneumatic rig, and pressure mapping of the articular surfaces performed with pressure sensitive film (SPI, New Jersey, USA). Following mapping, each specimen underwent 10,000 cycles of flexion and extension over a three-hour period. When testing was complete, pressure mapping was again performed, the size of the step-off re-measured using the CNM, and surface roughness of the menisci, femoral condyles and tibial plateau assessed. Data was restored on a laptop for subsequent statistical analysis. Results: Pressure mapping documented an unloaded area on the low side of the step-off in both Group C and S. This extended up to 8mm, and was mirrored by an area of increased load on the high side. Following testing, the area exposed to altered loads on both the high and low side of the osteotomy had diminished. On ANOVA testing the uncovered tibial articular surfaces in test subjects were significantly rougher than control specimens, though no difference was noted between Groups C and S (Mean Ra value GC: 101.83+22.78, GS: 93.52+17.89, ns. vs. Con 53.45+25.8,p< 0.05). Meniscal surface roughness was greater in the test groups, though this did not reach statistical significance. No significant difference in femoral condyle surface roughness was noted following testing. Nor was any difference noted in surface roughness in the submeniscal areas of the tibial articular surface. Discussion: The displaced femoral osteotomy resulted in an area of increased wear on the opposing tibial articular surface. However no significant difference was noted between the coronal and sagittal group. It is probable that the menisci negated the effect of fracture line orientation. We suggest that they minimized secondary articular damage by decreasing the area of direct tibiofemoral contact. Furthermore the elasticity of the menisci, in addition to their ability to move in the anteroposterior plane further decreased stress transmission between joint surfaces. Further studies will be performed on the hip joint to determine the effect of articular incongruity in the absence of such a fibrocartilage buffer

Introduction. Rolando type base of thumb metacarpal fractures are potentially debilitating injuries, which can be difficult to manage because of their inherent instability. Malunion is associated with stiffness, pain and weakness of pinch grip. We aimed to assess the outcome of a simple technique for the treatment of this fracture using the principle of ligamentotaxis, with a static, 2-pin external fixator spanning the trapeziometacarpal joint. We present the results and functional outcomes of this technique. Methods. A consecutive series of 8 patients (7 males, 1 female) with Rolando type intra-articular fractures of the base of the first metacarpal was retrospectively reviewed. All cases were performed by the senior author using a static, 2-pin Mini-Hoffman external fixator. Case notes and radiographs were reviewed, and patients' functional outcome assessed using the Quick Disability of Arm, Shoulder and Hand (Quick DASH) scoring system. Mean age of the group was 32.8 years (range 18.1-52.3 years). Mean follow-up was 2.7 years (range 3.5 months to 6.0 years). Results. The mean delay between injury and surgery was 6.6 days (range 1-11). The mean time to frame removal was 28 days (range 15-41). There were 3 cases of superficial pin site infection all of which were treated satisfactorily with oral antibiotic therapy. Follow-up radiographs did not demonstrate any significant joint incongruity or malunion in any case. The mean Quick DASH score was 8 (range 0-23). Mean scores for the work and sport components were 10 (range 0-25) and 3 (range 0-6) respectively. Conclusion. The results of this study demonstrate that this simple method reliably gives excellent hand and thumb function with minimal impact upon work, sport or recreational activities. We recommend the use of spanning trapeziometacarpal external fixation for intra-articular fractures of the base of the first metacarpal

Background: A classification of intra-articular fractures of the distal radius is described on the basis of observations of consistent patterns of fracture fragmentation and displacement. The Melone intra-articular classification system categorizes articular fractures into 4 types, with the medial complex assuming a pivotal position as the cornerstone of both the radiocarpal and distal radio-ulnar joints. The purpose of this study was to classify AO type-C3 fractures according to the Melone classification system using preoperative CT scan data. Methods: We retrospectively reviewed the clinical records of all patients who underwent open reduction and internal fixation (ORIF), according to the AO type-C3 classification. Between September, 2006, and May, 2009, 36 patients and a total of 38 fractures were identified. These intra-articular fractures were also classified according to the Melone classification system using preoperative CT scan data. We also investigated a bone fracture type and surgicalprocedures. Results: Nine fractures were divided into Melone type-1, 17 into type-2 (anterior displacement), 6 into type-2 (posterior displacement), 2 into type-3, and 4 into type-4. Thirty fractures were treated using plate fixation, and 8 fractures were treated using nail fixation. Melone type-1 fractures were usually treated with nail fixation, whereas type-2, -3, and -4 fractures were usually treated using plate fixation. Conclusions: Classification according to the Melone classification system using preoperative CT scan data enables the identification and elucidation of displacement in the major fracture components and enables the establishment of rational guidelines for the management of ORIF

Introduction: There is still debate on the effect of operative treatment on severe displaced intra-articular fractures of the os calcis. Operatively treatment consists of open reduction or percutanious screw fixation, with conflicting results. Although the results of either operative treatment are published, little is known about the long term results of non-surgical treatment of these difficult fractures. Patients and Methods: We analyzed the data of 35 patients with an intra-articular fracture of the oc calcis which were treated with a plaster cast between 1994 and 2006. All radiographs of the fracture and the radiograph at the latest follow-up were analyzed. All patients which could be traced were invited for a clinical examination and a radiograph. A Foot Function Index-score (FFI) and AOFAS score were recorded as clinical outcome. A regression analysis was performed with the clinical outcome (AOFAS score and FFI) as outcome and age, gender, Bohler’s and Gissane’s angles, trauma mechanism and type of fracture as predictors. Results: After a median follow-up of 10 years the mean AOFAS score was 75.8 (range29–100) and the FFI was 22.9 (range 0–71). In the regression analysis we found that none of the predictors could predict the outcome. Even the Bohler’s and Gisae angle did not predict the clinical outcome. Although there was a strong correlation between the Bohler’s angle on the lateral radiograph and the occurrence of degenerative changes in the long term follow-up, both Bohler’s angle and the degenerative changes did not correlate with the clinical measures. Conclusion: Although Bohler’s angle is a strong predictor for degenerative changes after a calcaneal fracture, both Bohler’s angle and the degenerative changes on the radiograph were not correlated with the clinical outcome

Introduction. The reliability of currently available proximal humeral fracture classi?cation systems has been shown to be poor, giving rise to the question whether a more objective measure entails improved predictability of surgical outcome. This study aims to apply a novel software system to predict the functional range of motion of the glenohumeral joint after proximal humeral fracture. Method. Using a validated system that simulates bone-determined range of motion of spheroidal joints such as the shoulder joint, we categorically analysed a consecutive series of 79 proximal humeral fractures. Morphological properties of the proximal humerus fractures were related to simulated bone-determined range of motion. Results. The interobserver variability of range of motion assessment using our system showed excellent agreement (0.798). Maximal glenohumeral abduction and forward ?exion of intra-articular fractures were 34.3±6.6 SE and 60.7±12.4 SE degrees. For fractures with a displaced greater tuberosity abduction was 75.0±5.9 SE and forward flexion was 118.2±4.9 SE degrees, whilst for fractures where both tuberosities had been displaced they were 60.0±10.9 SE and 69.6±13.4 SE degrees respectively. For non-intra articular fractures without displaced tuberosities movements were 89.3±3.3 SE and 122.6±3.4 SE degrees respectively. The head inclination angle was positively correlated with maximum abduction (0.362, p = 0.014). Offset was negatively correlated with maximum abduction, but not statistically signi?cant (0.834, p = 0.087). Conclusion. This study has demonstrated a novel and effective tool allowing the prediction of functional motion after proximal humeral fracture based on bone anatomy. The study demonstrates that intra-articular fractures generally have the worst prognosis with regards to bone-determined ROM. Fractures with displaced tuberosities show more motion limitations for abduction than for forward ?exion. A reduced head inclination angle is a strong predictor of limited bone-determined range of motion for all types of proximal humerus fractures

A high rate of complications is associated with open reduction and internal fixation of Sanders type 4 fractures of the calcaneum. We assessed the long-term outcome of 83 Sanders type 4 comminuted intra-articular fractures of the calcaneum in 64 patients who underwent non-operative treatment between 1999 and 2005. Each fracture was treated by closed reduction and immobilisation in a long leg cast. Patients were reviewed every three months in the first year, and every six months thereafter. At each visit, the involved ankles were assessed by the American Orthopaedic Foot and Ankle Society (AOFAS) criteria. The degree of fracture healing and the presence of osteoarthritis were assessed. At a mean follow-up of 51 months (24 to 70) the mean AOFAS score was 72 (52 to 92). Osteoarthritis was scored radiologically using Graves’ classification and was evident in the subtalar joints of 75 ankles (90%) on x-ray and in all ankles on CT scans, of which 20 were grade 0 or 1, 39 grade 2, and 24 grade 3. A non-operative approach to treating these fractures may be simpler, less expensive, easier to administer with fewer complications, and may be better tolerated than surgery, by many patients
