Aims. The aim of this study was to investigate the association between fracture displacement and survivorship of the native hip joint without conversion to a total hip arthroplasty (THA), and to determine predictors for conversion to THA in patients treated nonoperatively for acetabular fractures. Methods. A multicentre cross-sectional study was performed in 170 patients who were treated nonoperatively for an acetabular fracture in three level 1 trauma centres. Using the post-injury diagnostic CT scan, the maximum gap and
Aims. The primary aim of this study was to address the hypothesis that fracture morphology might be more important than posterior malleolar fragment size in rotational type posterior malleolar ankle fractures (PMAFs). The secondary aim was to identify clinically important predictors of outcome for each respective PMAF-type, to challenge the current dogma that surgical decision-making should be based on fragment size. Methods. This observational prospective cohort study included 70 patients with operatively treated rotational type PMAFs, respectively: 23 Haraguchi Type I (large posterolateral-oblique), 22 Type II (two-part posterolateral and posteromedial), and 25 (avulsion-) Type III. There was no standardized protocol on how to address the PMAFs and CT-imaging was used to classify fracture morphology and quality of postoperative syndesmotic reduction. Quantitative 3D-CT (Q3DCT) was used to assess the quality of fracture reduction, respectively: the proportion of articular involvement; residual intra-articular: gap,
Aims. Proper preoperative planning benefits fracture reduction, fixation, and stability in tibial plateau fracture surgery. We developed and clinically implemented a novel workflow for 3D surgical planning including patient-specific drilling guides in tibial plateau fracture surgery. Methods. A prospective feasibility study was performed in which consecutive tibial plateau fracture patients were treated with 3D surgical planning, including patient-specific drilling guides applied to standard off-the-shelf plates. A postoperative CT scan was obtained to assess whether the screw directions, screw lengths, and plate position were performed according the preoperative planning. Quality of the fracture reduction was assessed by measuring residual intra-articular incongruence (maximum gap and step-off) and compared to a historical matched control group. Results. A total of 15 patients were treated with 3D surgical planning in which 83 screws were placed by using drilling guides. The median deviation of the achieved screw trajectory from the planned trajectory was 3.4° (interquartile range (IQR) 2.5 to 5.4) and the difference in entry points (i.e. plate position) was 3.0 mm (IQR 2.0 to 5.5) compared to the 3D preoperative planning. The length of 72 screws (86.7%) were according to the planning. Compared to the historical cohort, 3D-guided surgery showed an improved surgical reduction in terms of median gap (3.1 vs 4.7 mm; p = 0.126) and
Aims. To compare operative and nonoperative treatment for displaced distal radius fractures in patients aged over 65 years. Methods. A total of 100 patients were randomized in this non-inferiority trial, comparing cast immobilization with operation with a volar locking plate. Patients with displaced AO/OTA A and C fractures were eligible if one of the following were found after initial closed reduction: 1) dorsal angulation > 10°; 2) ulnar variance > 3 mm; or 3) intra-articular
A new anterior intrapelvic approach for the surgical
management of displaced acetabular fractures involving predominantly
the anterior column and the quadrilateral plate is described. In
order to establish five ‘windows’ for instrumentation, the extraperitoneal
space is entered along the lateral border of the rectus abdominis
muscle. This is the so-called ‘Pararectus’ approach. The feasibility
of safe dissection and optimal instrumentation of the pelvis was
assessed in five cadavers (ten hemipelves) before implementation
in a series of 20 patients with a mean age of 59 years (17 to 90),
of whom 17 were male. The clinical evaluation was undertaken between
December 2009 and December 2010. The quality of reduction was assessed
with post-operative CT scans and the occurrence of intra-operative
complications was noted. In cadavers, sufficient extraperitoneal
access and safe instrumentation of the pelvis were accomplished.
In the patients, there was a statistically significant improvement
in the reduction of the fracture (pre- versus post-operative:

Introduction:. Bicondylar tibial plateau fractures are serious periarticular injuries. We investigated outcomes in injuries managed with Ilizarov external fixators. Methods:. We retrospectively reviewed bicondylar tibial plateau fractures treated with Ilizarov fixators in a major trauma centre from 2008–2012. Radiological parameters were measured from standardised weight-bearing radiographs. A subset (n=34) had patient-related outcome measures. Results:. Of 80 injuries, all fractures united. Two developed septic arthritis and one osteomyelitis. 76.3% were graded a good-excellent outcome (Rasmussen radiological score). 30.3% had evidence of osteoarthritis (Kellgren Lawrence>1). Neither parameter correlated significantly with lower functional scores. Referrals from neighbouring hospitals had longer times to surgery, which associated with increased condylar widening (p=0.0214) and posterior tibial slope (p=0.0332). Risk of developing osteoarthritis correlated with lower joint line congruency angle (JLCA) (p=0.0017) and increased articular
We treated 24 patients with high-energy fractures of the tibial plateau by the Ilizarov fixator and transfixion wires. Eleven fractures were open, and 20 patients had complex injuries. Twelve were treated by ligamentotaxis and percutaneous fixation, seven by limited open reduction and five by extensive open reduction. All were followed for at least 24 months. All the fractures united, with an average time to healing of 14.4 weeks. Thirteen patients achieved full extension and 13 more than 110° of flexion. Twenty-two knees were stable. Fifteen patients walked normally and the rest with only a slight limp. All but two knees had an articular
No randomized comparative study has compared the extensile lateral approach (ELA) and sinus tarsi approach (STA) for Sanders type 2 calcaneal fractures. This randomized comparative study was conducted to confirm whether the STA was prone to fewer wound complications than the ELA. Between August 2013 and August 2018, 64 patients with Sanders type 2 calcaneus fractures were randomly assigned to receive surgical treatment by the ELA (32 patients) and STA (32 patients). The primary outcome was development of wound complications. The secondary outcomes were postoperative complications, pain scored of a visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, 36-item Short Form health survey, operative duration, subtalar joint range of motion (ROM), Böhler’s angle and calcaneal width, and posterior facet reduction.Aims
Methods
Tibial plateau fractures are serious injuries about the knee that have the potential to affect patients’ long-term function. To our knowledge, this is the first study to use patient-reported outcomes (PROs) with a musculoskeletal focus to assess the long-term outcome, as compared to a short-term outcome baseline, of tibial plateau fractures treated using modern techniques. In total, 102 patients who sustained a displaced tibial plateau fracture and underwent operative repair by one of three orthopaedic traumatologists at a large, academic medical centre and had a minimum of five-year follow-up were identified. Breakdown of patients by Schatzker classification is as follows: two (1.9%) Schatzker I, 54 (50.9%) Schatzker II, two (1.9%) Schatzker III, 13 (12.3%) Schatzker IV, nine (8.5%) Schatzker V, and 26 (24.5%) Schatzker VI. Follow-up data obtained included: Visual Analogue Scale (VAS) or Numeric Rating Scale (NRS) pain scores, Short Musculoskeletal Functional Assessment (SMFA), and knee range of movement (ROM). Data at latest follow-up were then compared to 12-month data using a paired Aims

To investigate the differences of open reduction and internal
fixation (ORIF) of complex AO Type C distal radius fractures between
two different models of a single implant type. A total of 136 patients who received either a 2.4 mm (n = 61)
or 3.5 mm (n = 75) distal radius locking compression plate (LCP

This paper investigates whether cortical comminution
and intra-articular involvement can predict displacement in distal
radius fractures by using a classification that includes volar comminution
as a separate parameter. A prospective multicentre study involving non-operative treatment
of distal radius fractures in 387 patients aged between 15 and 74
years (398 fractures) was conducted. The presence of cortical comminution
and intra-articular involvement according to the Buttazzoni classification
is described. Minimally displaced fractures were treated with immobilisation
in a cast while displaced fractures underwent closed reduction with
subsequent immobilisation. Radiographs were obtained after reduction,
at 10 to 14 days and after union. The outcome measure was re-displacement
or union. In fractures with volar comminution (Buttazzoni type 4), 96%
(53 of 55) displaced. In intra-articular fractures without volar
comminution (Buttazzoni 3), 72% (84 of 117) displaced. In extra-articular
fractures with isolated dorsal comminution (Buttazzoni 2), 73% (106
of 145) displaced while in non-comminuted fractures (Buttazzoni
1), 16 % (13 of 81 ) displaced. A total of 32% (53 of 165) of initially minimally displaced fractures
later displaced. All of the initially displaced volarly comminuted
fractures re-displaced. Displacement occurred in 31% (63 of 205)
of fractures that were still in good alignment after 10 to 14 days. Regression analysis showed that volar and dorsal comminution
predicted later displacement, while intra-articular involvement
did not predict displacement. Volar comminution was the strongest
predictor of displacement. Cite this article:
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.
It has previously been suggested that among unstable
ankle fractures, the presence of a malleolar fracture is associated
with a worse outcome than a corresponding ligamentous injury. However,
previous studies have included heterogeneous groups of injury. The
purpose of this study was to determine whether any specific pattern of
bony and/or ligamentous injury among a series of supination-external
rotation type IV (SER IV) ankle fractures treated with anatomical
fixation was associated with a worse outcome. We analysed a prospective cohort of 108 SER IV ankle fractures
with a follow-up of one year. Pre-operative radiographs and MRIs
were undertaken to characterise precisely the pattern of injury.
Operative treatment included fixation of all malleolar fractures.
Post-operative CT was used to assess reduction. The primary and
secondary outcome measures were the Foot and Ankle Outcome Score
(FAOS) and the range of movement of the ankle. There were no clinically relevant differences between the four
possible SER IV fracture pattern groups with regard to the FAOS
or range of movement. In this population of strictly defined SER
IV ankle injuries, the presence of a malleolar fracture was not
associated with a significantly worse clinical outcome than its
ligamentous injury counterpart. Other factors inherent to the injury
and treatment may play a more important role in predicting outcome.
We have examined the accuracy of reduction and the functional outcomes in elderly patients with surgically treated acetabular fractures, based on assessment of plain radiographs and CT scans. There were 45 patients with such a fracture with a mean age of 67 years (59 to 82) at the time of surgery. All patients completed SF-36 questionnaires to determine the functional outcome at a mean follow-up of 72.4 months (24 to 188). All had radiographs and a CT scan within one week of surgery. The reduction was categorised as ‘anatomical’, ‘imperfect’, or ‘poor’. Radiographs classified 26 patients (58%) as anatomical,13 (29%) as imperfect and six (13%) as poor. The maximum displacement on CT showed none as anatomical, 23 (51%) as imperfect and 22 (49%) as poor, but this was not always at the weight-bearing dome. SF-36 scores showed functional outcomes comparable with those of the general elderly population, with no correlation with the radiological reduction. Perfect anatomical reduction is not necessary to attain a good functional outcome in acetabular fractures in the elderly.
We performed a prospective, randomised trial to evaluate the outcome after surgery of displaced, unstable fractures of the distal radius. A total of 280 consecutive patients were enrolled in a prospective database and 88 identified who met the inclusion criteria for surgery. They were randomised to receive either bridging external fixation with supplementary Kirschner-wire fixation or volar-locked plating with screws. Both groups were similar in terms of age, gender, hand dominance, fracture pattern, socio-economic status and medical co-morbidities. Although the patients treated by volar plating had a statistically significant early improvement in the range of movement of the wrist, this advantage diminished with time and in absolute terms the difference in range of movement was clinically unimportant. Radiologically, there were no clinically significant differences in the reductions, although more patients with AO/OTA (Orthopaedic Trauma Association) type C fractures were allocated to the external fixation group. The function at one year was similar in the two groups. No clear advantage could be demonstrated with either treatment but fewer re-operations were required in the external fixation group.
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 identified 11 women with a mean age of 74 years (65 to 81) who sustained comminuted distal radial and ulnar fractures and were treated by volar plating and slight shortening of the radius combined with a primary Sauvé-Kapandji procedure. At a mean of 46 months (16 to 58), union of distal radial fractures and arthrodesis of the distal radioulnar joint was seen in all patients. The mean shortening of the radius was 12 mm (5 to 18) compared to the contralateral side. Flexion and extension of the wrist was a mean of 54° and 50°, respectively, and the mean pronation and supination of the forearm was 82° and 86°, respectively. The final mean disabilities of the arm, shoulder and hand score was 26 points. According to the Green and O’Brien rating system, eight patients had an excellent, two a good and one a fair result. The good clinical and radiological results, and the minor complications without the need for further operations related to late ulnar-sided wrist pain, justify this procedure in the elderly patient.
A total of 30 patients with lateral compression fractures of the pelvis with intra-articular extension into the anterior column were followed for a mean of 4.2 years (2 to 6), using the validated functional outcome tools of the musculoskeletal function assessment and the short-form health survey (SF-36). The functional outcome was compared with that of a series of patients who had sustained type-B1 and type-C pelvic fractures. The lateral-compression group included 20 men and ten women with a mean age of 42.7 years (13 to 84) at the time of injury. Functional deficits were noted for the mental component summary score (p = 0.008) and in the social function domain (p <
0.05) of the SF-36. There was no evidence of degenerative arthritis in the lateral-compression group. However, they had high functional morbidity including greater emotional and psychological distress.
The generally-accepted treatment for large, displaced fractures of the glenoid associated with traumatic anterior dislocation of the shoulder is operative repair. In this study, 14 consecutive patients with large (>
5 mm), displaced (>
2 mm) anteroinferior glenoid rim fractures were treated non-operatively if post-reduction radiographs showed a centred glenohumeral joint. After a mean follow-up of 5.6 years (2.8 to 8.4), the mean Constant score and subjective shoulder value were 98% (90% to 100%) and 97% (90% to 100%), respectively. There were no redislocations or subluxations, and the apprehension test was negative. All fragments healed with an average intra-articular step of 3.0 mm (0.5 to 11). No patient had symptoms of osteoarthritis, which was mild in two shoulders and moderate in one. Traumatic anterior dislocation of the shoulder, associated with a large displaced glenoid rim fracture can be successfully treated non-operatively, providing the glenohumeral joint is concentrically reduced on the anteroposterior radiograph.
