Aims. Conservative treatment of moderately displaced proximal humeral head fractures yields good clinical results, but secondary fragment displacement may occur. Identification of those fractures at risk of displacement may influence initial decision-making. Methods. A total of 163 shoulders in 162 patients with conservatively treated isolated proximal humeral fractures were included. The fractures occurred between January 2015 and May 2018. The mean age of the patients was 69 years (26 to 100) and the mean follow-up was 144 days (42 to 779). The fractures were classified according to Neer. Scores for osteoporosis (Tingart, Deltoid Tuberosity Index (DTI)) and osteoarthritis (OA) of the glenohumeral joint were assessed. Translation of the head on follow-up radiographs of more than 10 mm was defined as displacement. Eccentric head index (EHI) describes the offset of the humeral head centre in relation to the diaphyseal axis. The ratio was estimated on anteroposterior (AP) and Neer views. Medial hinge was considered intact if the medial cortex proximal and distal to the fracture was in line on AP view. Results. Secondary fracture displacement occurred in 41 patients (25.2%). Clinical risk factors were alcohol abuse (odds ratio (OR) 6.8; 95% confidence interval (CI) 1.3 to 36; p = 0.025) and previously diagnosed osteoporosis (OR 4.6; 95% CI 0.6 to 34; p = 0.136). Age (OR 1.1; 95% CI 1.0 to 1.1; p = 0.003) and sex (OR 0.9; 95% CI 0.3 to 2.8; p = 0.867) were not independent factors. Radiological risk factors were OA grade 3 (OR 16.4; 95% CI 0.25 to 37.6; p = 0.107) and osteoporosis with the DTI (OR 10; 95% CI 0.8 to 250; p = 0.031) being more predictive than the Tingart score (OR 2.3; 95% CI 0.8 to 4.7; p = 0.041). A high EHI (AP/Neer > 0.4, OR 18.9; 95% CI 2.1 to 30.9/3.0; 95% CI 1.1 to 8.0; p = 0.002/p = 0.033) and a disrupted medial hinge (OR 3.7; 95% CI 1.1 to 12.6; p = 0.039) increased the risk of secondary displacement significantly. Neer classification had no influence. Conclusion. During conservative treatment, a quarter of patients showed secondary fracture displacement of at least 10 mm. Patients with alcohol abuse, severe OA, and osteoporosis are at risk. Newly defined EHI and disrupted medial hinge are relevant predictors for secondary displacement.

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

Aims. In order to determine whether and for whom serial radiological evaluation is necessary in one-part proximal humerus fractures, we set out to describe the clinical history and predictors of secondary displacement in patients sustaining these injuries. Patients and Methods. Between January 2014 and April 2016, all patients with an isolated, nonoperatively treated one-part proximal humerus fracture were prospectively followed up. Clinical and radiological evaluation took place at less than two, six, 12, and 52 weeks. Fracture configuration, bone quality, and comminution were determined on the initial radiographs. Fracture healing, secondary displacement, and treatment changes were recorded during follow-up. Results. In 100 patients (59 female, 41 male; mean age 57 years), 91 of the fractures (91%) remained stable. In five of nine patients (55%) with secondary displacement, surgery was recommended. Comminution, present in 23 patients (23%), was identified as a predictor of secondary displacement (p < 0.001). Patients’ age, sex, fracture configuration, and bone quality were not associated with secondary displacement (p ≥ 0.438). Nonoperative treatment resulted in a mean absolute Constant score (CS) of 80 (49 to 98), relative CS of 101% (63% to 138%), median subjective shoulder value of 95% (interquartile range (IQR) 90% to 100%), and median EuroQol five-dimensional questionnaire score of 0.89 (IQR 0.80 to 1.00) with bone union in all cases at one-year follow-up. Conclusion. Radiological re-evaluation was only necessary in patients presenting with comminution and may be redundant for 77% of patients with one-part proximal humerus fractures. Nonoperative treatment of one-part proximal humerus fractures remains the mainstay of treatment with a low rate of secondary surgery, a high union rate, and good clinical results.

Background. Undisplaced Lisfranc-type injuries are subtle but potentially unstable fracture-dislocations with little known about the natural history. These injuries are often initially managed conservatively due to lack of initial displacement and uncertainty regarding subsequent instability at the tarsometatarsal joints (TMTJ). The aim of this study was to determine the secondary displacement rate and the need for delayed operative intervention in undisplaced Lisfranc injuries that were managed conservatively at initial presentation. Methods. Over a 6-year period (2011 to 2017), we identified 24 consecutive patients presenting to a university teaching hospital with a diagnosis of an undisplaced Lisfranc-type injury that was initially managed conservatively. Pre-operative radiographs were reviewed to confirm the undisplaced nature of the injury (defined as a diastasis< 2mm at the second TMTJ). The presence of a ‘fleck’ sign (small bony avulsion of the second metatarsal) was also noted. Electronic patient records and sequential imaging (plain radiographs/CT/MRI) were scrutinized for demographics, mechanism of injury and eventual outcome. Results. The mean age of the patients at the time of injury was 42 years (19 Female). 96% (23/24) were low energy injuries and 88% (21/24) had a positive ‘fleck sign’. The secondary displacement rate in this group of patients was 62.5% (15/24) over a median interval of 14 days (range 0 to 482 days). 12 patients underwent open reduction internal fixation after a median interval of 29 days (range 1 to 294 days) from their initial injury. One patient required TMTJ fusion at 19 months and two patients were managed non-operatively. The injury remained undisplaced in 37.5% patients (9/24) with only one patient requiring subsequent TMTJ fusion at 5 months. Conclusion. Undisplaced Lisfranc injuries have a high rate of secondary displacement and warrant close follow-up. Early primary stabilisation of undisplaced Lisfranc injuries should be considered to prevent unnecessary delays in surgical treatment

Distal radius fractures (DRFs) are common injuries that represent 17% of all adult upper extremity fractures. Some fractures deemed appropriate for nonsurgical management following closed reduction and casting exhibit delayed secondary displacement (greater than two weeks from injury) and require late surgical intervention. This can lead to delayed rehabilitation and functional outcomes. This study aimed to determine which demographic and radiographic features can be used to predict delayed fracture displacement. This is a multicentre retrospective case-control study using radiographs extracted from our Analytics Data Integration, Measurement and Reporting (DIMR) database, using diagnostic and therapeutic codes. Skeletally mature patients aged 18 years of age or older with an isolated DRF treated with surgical intervention between two and four weeks from initial injury, with two or more follow-up visits prior to surgical intervention, were included. Exclusion criteria were patients with multiple injuries, surgical treatment with fewer than two clinical assessments prior to surgical treatment, or surgical treatment within two weeks of injury. The proportion of patients with delayed fracture displacement requiring surgical treatment will be reported as a percentage of all identified DRFs within the study period. A multivariable conditional logistic regression analysis was used to assess case-control comparisons, in order to determine the parameters that are mostly likely to predict delayed fracture displacement leading to surgical management. Intra- and inter-rater reliability for each radiographic parameter will also be calculated. A total of 84 age- and sex-matched pairs were identified (n=168) over a 5-year period, with 87% being female and a mean age of 48.9 (SD=14.5) years. Variables assessed in the model included pre-reduction and post-reduction radial height, radial inclination, radial tilt, volar cortical displacement, injury classification, intra-articular step or gap, ulnar variance, radiocarpal alignment, and cast index, as well as the difference between pre- and post-reduction parameters. Decreased pre-reduction radial inclination (Odds Ratio [OR] = 0.54; Confidence Interval [CI] = 0.43 – 0.64) and increased pre-reduction volar cortical displacement (OR = 1.31; CI = 1.10 – 1.60) were significant predictors of delayed fracture displacement beyond a minimum of 2-week follow-up. Similarly, an increased difference between pre-reduction and immediate post reduction radial height (OR = 1.67; CI = 1.31 – 2.18) and ulnar variance (OR = 1.48; CI = 1.24 – 1.81) were also significant predictors of delayed fracture displacement. Cast immobilization is not without risks and delayed surgical treatment can result in a prolong recovery. Therefore, if reliable and reproducible radiographic parameters can be identified that predict delayed fracture displacement, this information will aid in earlier identification of patients with DRFs at risk of late displacement. This could lead to earlier, appropriate surgical management, rehabilitation, and return to work and function

Aims. Our retrospective analysis reports the outcome of patients operated for slipped capital femoral epiphysis using the modified Dunn procedure. Results, complications, and the need for revision surgery are compared with the recent literature. Methods. We retrospectively evaluated 17 patients (18 hips) who underwent the modified Dunn procedure for the treatment of slipped capital femoral epiphysis. Outcome measurement included standardized scores. Clinical assessment included ambulation, leg length discrepancy, and hip mobility. Radiographically, the quality of epiphyseal reduction was evaluated using the Southwick and Alpha-angles. Avascular necrosis, heterotopic ossifications, and osteoarthritis were documented at follow-up. Results. At a mean follow-up of more than nine years, the mean modified Harris Hip score was 88.7 points, the Hip Disability and Osteoarthritis Outcome Score (HOOS) 87.4 , the Merle d’Aubigné Score 16.5 points, and the UCLA Activity Score 8.4. One patient developed a partial avascular necrosis of the femoral head, and one patient already had an avascular necrosis at the time of delayed diagnosis. Two hips developed osteoarthritic signs at 14 and 16 years after the index operation. Six patients needed a total of nine revision surgeries. One operation was needed for postoperative hip subluxation, one for secondary displacement and implant failure, two for late femoroacetabular impingement, one for femoroacetabular impingement of the opposite hip, and four for implant removal. Conclusion. Our series shows good results and is comparable to previous published studies. The modified Dunn procedure allows the anatomic repositioning of the slipped epiphysis. Long-term results with subjective and objective hip function are superior, avascular necrosis and development of osteoarthritis inferior to other reported treatment modalities. Nevertheless, the procedure is technically demanding and revision surgery for secondary femoroacetabular impingement and implant removal are frequent. Cite this article: 2020;1-4:80–87

Purpose of the study: Treatment of distal fractures of the radius with posterior displacement remains a controversial issue. In the past, the anterior approach used for osteosynthesis failed to enable sustained reduction. With the recent development of locked plating systems, it might be useful to revisit this technique. Material and methods: Between November 2001 and April 2003, 23 patients (15 females, 8 males), mean age 55 years (range 17–75 years) were treated with an LCP 3.5 T plate (Mathys Medical SA, Bettlach, Switzerland). The anterior Henry approach was used. There were 16 extra-articular fractrures and seven with an associated intra-articular fracture line. Radiographic analysis searched for secondary displacement and was coupled with clinical examination with force measurement (DASH). The Herzberg score used for the SOFCOT 1999 symposium was noted. Results: Eighteen patients were reviewed with mean follow-up of 16 months. Radiologically, all fractures had healed at twelve months, with only one case of secondary loss of reduction. According to the SOFCOT symposium criteria, bone healing was anatomic for 13 cases and with moderate misalignment for five. Wrist force (Jamar) on the operated side was 95% of the opposite side. The mean DASH was 22.7. The Herzberg outcome was: excellent (n=9), good (n=6), fair (n=3), and poor (n=0). Complications were: reflex dystrophy (n=4), carpal tunnel syndrome (n=1), cheloid scar (n=1), irritation of the common extensor of the fingers (n=1). Discussion: Secondary displacement after fracture of a posteriorly displaced fracture of the distal radius frequently lead to misalignment which is often poorly tolerated. The LCP system maintains a stable reduction long enough to reduce the rate of secondary displacement. Conclusion: A comparative study of the commonly applied techniques (pinning) would be necessary to define the appropriate indications for this more costly technique

Purpose of the study: Pelvic fractures disrupting the pelvic girdle often create a serious challenge for reduction and fixation. Type C fractures of the Tile classification provoke vertical instability. Percutaneous screw fixation under fluoroscopic control in patients positioned in dorsal decubitus enables an extension of early indications for fixation to patients with abdominal or thoracic injuries. The reduction is obtained by progressive transcondylar traction on an orthopedic table. The purpose of this study was to assess functional mid-term outcome and to analyze causes of failure. Material and methods: From 1995 through 2003, we used the percutaneous sacroiliac screw fixation method for type C fractures in 25 patients; clinical assessment at 45 months mean follow-up was available for 22 patients. Six patients presented a bilateral lesion (C2), seven a vertical sacral fracture (C1-3), and nine sacroiliac disjunction (C1-2). One screw was inserted for ten patients, two screws for twelve. Complementary anterior osteosynthesis was performed for eight patients. Results: The functional outcome was assessed with the Mageed score. The mean score was 801%. All patients presente satisfactory postoperative reduction (less than 10 mm residual vertical displacement). Early displacement was noted one day 10 in one patient who underwent a revision procedure. There were two late secondary displacements (one with mobilization and one with material fracture) which heal in a misaligned position. There were no iatrogenic complications (neurologic, vascular, infectious) and no cases of nonunion. Discussion: The long-term functional results were directly related to the quality of the reduction, as previously demonstrated by Matta. In our series, the quality of the postoperative reduction was significantly correlated with time from trauma to surgery. This delay must be as short as possible (less than five days for Routt). The main complication was secondary displacement which was observed in this study among cases with a single posterior screw. Conclusion: Percutaneous sacroiliac screw fixation provides good functional results and appears to be a safe technique if the initial reduction is satisfactory. Two posterior screws are needed to avoid secondary displacement

Purpose: Management of supracondylar fractures of the humerus becomes a controversial issue when there is major displacement. The risk of vessel and nerve injury is very high, making reduction and fixation particularly difficult. Material and methods: We conducted a retrospective analysis of 100 supracondylar fractures managed over a ten year period. All of these fractures were in extension and exhibited a bone gap. We analysed early and late complications. Results and discussion: Mean age at trauma was 6.5 years, with six boys for four girls. The left side was involved in 69% of the cases. Falls were the predominant cause (48%). Thirty-two percent of fractures were complicated initially: nerve injury (n=17), vascular injury (n=12) (including three cases with nerve and vascular injury), open fractures (n=7). The medial nerve was injured in most cases (n=12). Ulnar palsy was noted in four patients and radial palsy in one. Vessel injury led to abolition of the radial pulse in eight patients and the ulnar pulse in one; all resolved after reduction. Ischaemia of the hand was noted in two cases before reduction of the fracture but vascular surgery was not required. Most of the fixations were achieved with cross pinning (percutaneous insertion in 47 patients and open surgery in 13). Despite minimal medial skin incision, ulnar nerve deficiency was observed after surgery in seven cases; four were rapidly regressive and three required surgical exploration with neurolysis. Six revision procedures were required for secondary displacement (10%). The 26 Judet fixations led to ten secondary displacements requiring surgical revision for cross pinning. Four cases of postoperative ulnar nerve deficiency were noted: reoperation to release the nerve pinched in the fracture was required for only one patient. The Blount technique was used in nine cases with four secondary displacements, including one related to two sites of nerve impingement. Five cases of superficial pin tract infection which resolved rapidly and two cases of deep infection were noted in the early postoperative period. Formation of a varus ulnar callus was noted in five cases: two required secondary surgery for correction. Conclusion: Our results point out the high rate of vessel and nerve complications related to these supracondylar fractures of the humerus with displacement. We recommend cross pinning which is mechanically superior and which does not compromise the neurological result if a minimal medial incision is used

Purpose: Results of basal metatarsal osteotomy are generally unpredictable. We studied the very oblique BRT osteotomy with preservation of the proximal hinge and fixation using a threaded-head screw. We now use this technique as a routine procedure. Material: From 1999 to 2000, 125 metatarsal osteotomies were performed on 93 feet in 77 patients (mean age 55 years). Indications were metatarsalgia alone in 34 feet, associated with another osteotomy for 21 feet, iatrogenic for 18 feet, and anterior pes cavus for 20 feet. Method: The incision was dorsal (3 medial metatarsals) or medial for M1 or lateral for M5. The osteotomy was very oblique (60°), with removal of a thin wedge (max 3 mm) except for M1 or in case of pes cavus. The proximoplantar hinge was carefully preserved. The osteotomy was limited to the strict clinical needs and determined on the false lateral view. All patients were reviewed at six months and one year after surgery (mean follow-up 11 months). Results: The fixation was solid allowing weight bearing at 15 days. Metatarso-phalangeal motion was preserved. There was no secondary displacement but there were three cases with a ruptured hinge due to an insufficiently oblique osteotomy. At last follow-up there has been no transfer to neighbouring rows. For the pes cavus cases, the M1 osteotomy was associated with osteotomy of one or several lateral metatarsals in 13/20 feet in order to further raise the first metatarsal without risk of transfer metatarsalgia. Discussion: The BRT osteotomy provides an unprecedented reliability for proximal osteotomy with elevation of the metatarsus. It is highly dependent however on clinical assessment, as for any basal osteotomy, although the false lateral view is quite useful. Excessive dorsal elevation must be avoided; secondary elevation is avoided due to the absence of secondary displacement. This osteotomy can be performed easily on all five metatarsals for pes cavus. It is often associated with distal treatment of claw toes. Its association with calcaneum osteotomy is useful for extra-articular treatment of pes cavus to preserve long-term function. Conclusion: For the two indications metatarsalgia and pes cavus, the BRT osteotomy with elevation of the base is easy to perform, prevents secondary displacement, is precise, and preserves joint function. Precision depends almost totally on clinical evaluation. Results have been very encouraging. Finally, this osteotomy, which involves elevation of the base alone, is complementary to the Weil osteotomy which has specific indications for longitudinal harmonisation of the metatarsus

Introduction:. Tuberosity healing is strongly correlated with functional results in all series of three- and four-part fractures of the proximal humerus treated by hemiarthroplasty. We formed a working group to improve position of the implant and fixation of the tuberosities on an implant specifically intended for traumatology. Material and Methods:. An anatomic study on 11 cadavers and a prospective multicentre clinical study of 32 cases were performed to validate extrapolable original solutions at the patient scale: placement of the stem at a height indicated in relation to the insertion of the clavicular bundle of the pectoralis major, locking of the stem, placement (based on bone quality) of a variable volume metaphyseal frame (offset modular system® OMS®), avoiding medialisation of the tuberosities, and fixation of the tuberosities using strong looped sutures, brightly coloured so that they can be located more easily. Evaluation by Dash score and Constant score was correlated with positioning of the tuberosities using radiographs. Results:. The clinical study enabled a distance of the top of the head to pectoralis major of 5.5 cm +/− 5 mm to be determined, confirming the results of the anatomic study and data from the literature. The distal double-locking ancillary device and the suturing technique for the tuberosities using looped sutures was judged to be effective by all of the surgeons. 23 patients (5 males, 9 CT4 and 8 CT3) with an mean age 69,6 (33–90) were operated on by 3 senior surgeons and reviewed at a mean follow-up of 17,3 months (6–24). All patients were seen again at 3 months and 6 months and the average motion at last follow was abduction of 90,7° (140–40), active anterior elevation of 113,25° (160–60), and external rotation of 43,2°(55–30). One complication was noted: inadequate position of a locking screw. In the 17 patients operated without oms® 50% had adequate initial positioning of the tuberosities and 10% secondary displacement. In comparison the 6 patients operated with the oms® 100% had adequate initial positioning of the tuberosities and no secondary displacement occurred. Discussion:. The series from Sofcot, Boileau, and more recently Reuther yielded results of 40 to 66% malposition or nonunion of the tuberosities. The initial clinical results from our series are encouraging and demonstrate that using a variable volume metaphyseal frame in synthesis of the tuberosities with control of the height of the implant is reliable. This multicentre study should be extended by a more long-term analysis

Objective: The main treatment for unstable distal radius fracture in Québec consists in pinning and cast, with secondary shortening and displacement responsible for lack of motion. The goal of the study is to compare clinical and radiological results after treatment with non-bridging external fixator compared to pinning and cast, with restoration of grip strength as main clinical outcome. Method: Between June 2003 and June 2005, 120 consecutive patients admitted for unstable extra-articular distal radius fracture were randomized in the 2 groups. Early mobilisation was allowed in the group with external fixator, and patients in the other group had pins and cast for 6 weeks. Follow-up was completed after 6 months with determination of clinical and radiological data for the both wrists. 110 patients completed the study, with 2 comparative groups for epidemiologic and radiological criteria (n = 63 for pins and 57 for external fixator). Results: Grip strength was significantly better in the fixator group at 3 months (68,36%;p< 0,001) and 6 months (98,26%;p< 0,001). Active ROM was better and obtained earlier in the fixator group in all directions (p< 0,001). Fixator prevent shortening and secondary displacement in a highly significant way (p< 0,001). No difference in pain medication, but fixator group could begin occupation earlier (p< 0,001). Conclusion: Non-bridging external fixator is a treatment of choice for unstable extra-articular distal radius fractures. The immediate stability allows in all patients (without influence of age, bone quality or fracture displacement) early mobilisation, prevent secondary displacement, and gives earlier and better functional results

Purpose of the study: We report our experience with the LCP DRP 2.4 plate with a locking screw for the treatment of distal factures of the radius. Material and methods: Between 2003 and June 2004, 67 displaced fractures of the distal radius were treated with a LCP DRP 2.4 system. Patients were subsequently immobilized in a removable anatomic orthesis for three weeks. The Fernandez, Castaign and AO classifications were used. Clinical evaluation was based on the DASH test, the Green and O’Brien score and the PWRE. Results: Clinical assessment was available for 59 patients who also responded to the questionnaires. Mean follow-up was eight months. Healing was achieved in six weeks. There were no cases of secondary displacement nor of lost reduction. The mean Green and O’Brien assessment was 85% good and very good outcome, the mean DASH score was 20.6 and the mean PWRE was 32.8. Discussion: Appropriate fixation for fractures of the distal radius remains a controversial issue, as illustrated by the variety of treatments used, the different materials proposed for fixation, and the large number of publications. The primary stability achieved with the locking screw in the LCP plate enables early rehabilitation. The absence of secondary displacement, irrespective of the quality of the bone, enables equivalent results in osteoporotic patients as in younger patients. No other material has enabled equivalent results to date. This is a major advance in osteosynthesis

Purpose of the study: Defective reduction and secondary displacement after osteosynthesis of distal radius fractures can compromise wrist function. Volar locking plates enable solid fixation which remains stable over time but section of the pronator quadrates necessary for the anterior approach raises the risks of destabilising the distal radioulnar joint and loss of pronation force. Our study was designed to evaluate recovery of grip, pronation and supination force after volar locking plate fixation. Material and methods: This was a prospective study of 29 fractures of the distal radius with dorsal displacement fixed with a volar locking plate in 28 patients (17 men, 11 women, mean age 48.75 years) from January 2007 to May 2008. The quality of the pronator quadrates suture was assessed at the end of the operation. The assessment included the classical parameters of wrist movement, the Herzberg and Dumontier score, radial slope and ulnar variance on the ap and lateral views of the wrist, and recovery of grip, pronation and supination force compared with the opposite side using an ambulatory device. Results: The pronator quadratus suture was considered solid in eight cases, precarious in seven. Complete suture was not possible in 14 cases. At mean follow-up of 10 months, patients had on average recovered 77% of the grip force, 74% of the pronation force, and 76% of supination force, compared with the opposite side. Complications included one defective reduction, one secondary displacement (by defective plate position), two dystrophy syndromes, and four posttrauma carpal tunnel syndromes. Discussion: The literature shows that volar plate fixation enables recovery of 74% to 84% of grip force. Few studies have examined the recovery of pronosupination and none have described results after osteosynthesis for fracture. Our study did not find that section of the pronator quadrates, a muscle difficult to suture, had a deleterious effect. Conclusion: Osteosynthesis using a volar locking plate for distal fractures of the radius remains a controversial issue. Study of recovery of the grip, pronation and supination force did not reveal any prejudice attributable to this technique

Purpose of the study: Fractures of the metacarpals are common injuries generally observed in young males. Nailing, either with a centromedullary configuration or intermetacarpal construction is generally proposed. The nailing procedure nevertheless has its drawbacks: fracture instability, secondary displacement, pin migration, infection, requirement to remove material, injury to the cutaneous dorsal branch of the ulnar nerve, and most importantly, immobilisation for several weeks which is a major inconvenience for these young active patients. In this context, we wanted to compare two fixation systems: a locked plate versus centromedullary nailing. Material and methods: This was a retrospective comparison of consecutive patients from September 2007 to December 2008. The series included 39 cervical fractures of the fifth metacarpal in 39 patients aged 31 years on average. The first 19 patients were treated with a locked plate (Médartis. ®. ) (group A) and the 20 others with descending centromedullary nailing (group B). In group A, a dorsal approach respecting the dorsal cutaneous branch of the ulnar nerve was used. The technique consisted in insertion of distal locking screws enabling fracture reduction on the plate. No postoperative immobilisation was proposed and rapid mobilisation was encouraged. In group B, classical centromedullary nailing was performed with immobilisation with a short Thomine brace and syndactylisation of the last two fingers. Outcome was based on objective criteria (Jamar. ®. force, joint motion, duration of sick leave) and subjective assessment (DASH, VAS). Results: Mean follow-up was 12 months in group A and 8 months in group B. Depending on the type of fracture, plates with different shapes and lengths were used in group A; a single pin was used in group B (16/10 or 20/10). Secondary displacement was more frequent in group B, but the results in recovered motion were better in group B. The only parameter better in group A was length of sick leave; four patients in group A underwent reoperation to remove the plate and for tenoarthrolysis. In all, the outcomes for cervical fractures of the fifth metatarsal were better in group B. Discussion: Our preliminary results in group A show lesser complications and earlier return to work compared with better motion at last follow-up in group B. Centromedullary nailing remains the better treatment for cervical fractures of the fifth metatarsal. The extra cost of the plates does not appear to be warranted for the treatment of neck fractures of the fifth even though the patient can resume occupational activities earlier

Purpose of the study: Locked centromedullary nailing has proven efficacy for the treament of tibial shaft fractures but its use remains controversial for the most distal fractures. The purpose of this work was to assess clinical and radiological outcome of nailing procedures used to treat fractures of the lower quarter of the leg. Material and methods: Fifty-eight fractures of the lower quarter of the leg were treated by locked centromedul-lary nailing between 1999 and 2002. All patients were included in the analysis. Twenty-four patients aged 44 years on average (range 18–68 years) were reviewed by an independent operator at mean 43.2 months follow-up (range 18–70). Four types of nail were used, on an orthopedic table for 47 procedures and with a hanging leg for 11. The fibula was not fixed. Results: Early complications were: compartment syndrome (n=2) and infection (n=3). Postoperative alignment was anatomic or good in 86%. Mean time to weight bearing was 66 days (range 0–180). Nonunion occurred in six patients who required revision. Secondary displacement was noted in ten patients. Knee motion was normal in all patients and ankle motion was normal in 80%. Mean time to resumed occupational activity was 5.7 months (range 1–18). At last follow-up, bone healing had been achieved in all patients. Discussion: As compared with data in the literature, we found that locked centromedullary nailing allows early weight bearing with less risk of infection for radiological results comparable with those obtained with plate fixation. The secondary displacements resulted from defective locking of inappropriately adapted materials (holes insufficiently distal). Conclusion: Locked centromedullary nailing is a treatment of choice for fractures of the distal quarter of the leg. Use of new nails with more distal holes should improve outcome by allowing distal locking with at least two screws in all cases

Introduction: Tibial plafond fractures constitute one of the most challenging injuries in orthopaedic surgery. Complications are common and clinical outcomes are generally poor. New guidelines for the management of these fractures and modern implants look forward to improving these results. Material and Methods: 40 tibial plafond fractures treated by open reduction and internal fixation between January 2006 and December 2008 were included prospectively. Fractures were classified according to the AO classification. A CT scan was required in17 intraarticular fractures. Definitive surgery was delayed until soft tissue injury had been healed. Eleven patients underwent provisional external fixation. Mean time to surgery was of 7.5 days (range, 0 to 40 days). 27 fractures were treated by anteromedial plating, 12 with anterolateral plating and in one case two plates were required. Bone grafting was used in 8 cases. Plain radiographs were used to determine axial alignment and time to healing. Reduction of the articular surface was considered anatomical when there was less of 1mm of displacement. The Ankle Osteoarthritis Score (AOS) was analysed for pain and disability. Statistical analysis was performed with the SPSS 12.0 for Windows. Results: According to the AO classification there were 22 Type A fractures, 9 Type B and 9 Type C. There were 7 open fractures (3 Type I, 3 Type II, 1 Type IIIA). Mean time to healing was of 18.1 weeks (8 to 32). Mean AOS score was of 41.2 points. There were 33 excellent and good results. There were 11 secondary losses of reduction and 5 non-union. Clinical results were correlated with the quality of the reduction and with secondary displacement (p=1 and p=0.69 respectively). Anatomic reduction was more frequent in Type A (81.8%) and B (88.9%) fractures than in Type C (77.8%). There were not statistically significant differences in the quality of the reduction (p=0.88) or in the appearance of secondary displacement (p=0.46) between anteromedial or anterolateral plating. There were 6 infections (4 following anteromedial plating and 2 after anterolateral plating which was not statistically significant p=0.88). 13 patients developed soft tissue complications. Five requiring soft tissue fiaps. Conclusion: Anteromedial and anterolateral plating of the distal tibia provide good clinical and radiological results. Infection rate is similar with both approaches. Appropriate timing of surgery can minimize soft tissue complications

We present the results of surgical treatment of proximal humeral fractures in a group of 40 patients. The fractures were treated with the angular stable Lockin Proximal Humeral Plate, which is based on the LCP-principle (Locking Compression Plate). The upper part of the plate contains small suture holes for fixation of the tuberosities. Between january 2002 and december 2005, 40 patients were operated using this technique. There were 24 women and 16 men and the mean age of our population was 56.5 years. Clinical and radiological evolution was followed until fracture fracture healing and functional recovery and a Constant-score was taken on a retrospective basis with a mean follow-up of 23.6 months. During follow-up 2 patients died of unrelated causes with their fractures healed and 2 patients were lost because they were living abroad. Fracture healing was uncomplicated in 34 patients (89 %). In 4 patients there was secondary displacement of the fracture: varus displacement in 3 cases and complete loosening of the osteosynthesis in a patient who fell again a few weeks after the first intervention. In this patient a new osteosynthesis with the same device was realised and the fracture healed correctly. In the other 3 cases the fracture healed with some varus alignment and in 1 of these the hardware had to be removed because of intra-articular positioning of some screws after varisation of the humeral head. No secondary displacement of the tuberosities was seen. In one case we had an aseptic necrosis of the humeral head 6 months after the osteosynthesis and this patient needed a shoulder arthroplasty. Another patient had severe chondral lesions of the humeral head but symptoms respond well to medical treatment. Hardware removal was necessary in 8 patients because of subacromial impingement or local tenderness. Reflex sympathetic dystrophy occured in 4 cases. The mean Constant-score was 57.6; when correction was made for age and gender the mean score was 73.0. Conclusion: The LPHP plate is a reliable implant for proximal humeral fractures but attention should be paid to the possibility of subacromial impingment and the plate should not be placed too high. Although the LCP-system allows for rigid fixation, some loosening of the humeral head screws in osteoporotic bone remains possible, leading to varus displacement of the humeral head. In these cases early mobilisation should be avoided. Secure fixation of the tuberosities through the proximal suture holes is also mandatory if early mobilisation is foreseen
