Double-plate fixation together with bridging bone grafting in nonunion of femoral supracondylar, subtrochanteric, and shaft fractures is an effective technique.

PURPOSE: The aims of the present study were to evaluate and report the therapeutic outcomes of double-plate fixation in combination with autogenous bridging bone grafting in treatment of nonunion fractures of femur. METHODS: In this retrospective case series study, 41 patients with nonunion fracture of femur who underwent surgery by double-plate fixation and autogenous bridging bone grafting in academic referral center from July 2010 to July 2015 were enrolled. Totally, 32 males and 9 females with mean age of 35 years were evaluated. They were evaluated for related risk factors, previous therapeutic methods, time interval between injury to nonunion surgery and surgery to full clinical and radiological union, duration of follow-up, levels of postoperative limb shortening, and movement limitations. RESULTS: Ten patients had open fractures and eight patients had infected nonunion in the femoral supracondylar, subtrochanteric, and shaft fractures. Nailing was the most common used method as the primary treatment of femoral shaft fractures. In addition, the mean follow-up time was 37 months. Full union was obtained even in infected cases. Deep vein thrombosis was found in one patient and pulmonary thromboembolism in another patient, and both patients were treated successfully. Moreover, limitations of articular movements were seen in seven patients. CONCLUSION: Double-plate fixation in combination with bridging bone grafting is an effective method in the treatment of nonunion of femoral supracondylar, subtrochanteric, and shaft fractures even in the infected cases.

Delay in weight bearing in surgically treated tibial shaft fractures is associated with impaired healing: a cohort analysis of 166 tibial fractures.

BACKGROUND: The relation between timing of weight bearing after a fracture and the healing outcome is yet to be established, thereby limiting the implementation of a possibly beneficial effect for our patients. The current study was undertaken to determine the effect of timing of weight bearing after a surgically treated tibial shaft fracture. MATERIALS AND METHODS: Surgically treated diaphyseal tibial fractures were retrospectively studied between 2007 and 2015. The timing of initial weight bearing (IWB) was analysed as a predictor for impaired healing in a multivariate regression. RESULTS: Totally, 166 diaphyseal tibial fractures were included, 86 cases with impaired healing and 80 with normal healing. The mean age was 38.7 years (range 16-89). The mean time until IWB was significantly shorter in the normal fracture healing group (2.6 vs 7.4 weeks, p < 0.001). Correlation analysis yielded four possible confounders: infection requiring surgical intervention, fracture type, fasciotomy and open fractures. Logistic regression identified IWB as an independent predictor for impaired healing with an odds ratio of 1.13 per week delay (95% CI 1.03-1.25). CONCLUSIONS: Delay in initial weight bearing is independently associated with impaired fracture healing in surgically treated tibial shaft fractures. Unlike other factors such as fracture type or soft tissue condition, early resumption of weight bearing can be influenced by the treating physician and this factor therefore has a direct clinical relevance. This study indicates that early resumption of weight bearing should be the treatment goal in fracture fixation. LEVEL OF EVIDENCE: 3b.

Rehabilitation of neglected Monteggia fracture: Dislocations in children.

PURPOSE: There are limited studies related to the rehabilitation of neglected Monteggia fracture-dislocations. This study reports the results of the rehabilitation of neglected Monteggia fractures and dislocations and the best treatment options available. MATERIAL AND METHODS: Thirteen children were rehabilitated between 2009 and 2012. A retrospective chart review was conducted to record the following: age, gender, anatomic region of fractures, time delay from symptom onset to fracture, Bado classification, Mayo Elbow Performance Index (MEPI) which includes pain, range of motion and daily life comfort, surgeries, length of hospitalization, location and pattern of fracture, length of follow-up and complications. RESULTS: The study group included thirteen children and adolescents; eleven males and two females with a mean age of 8.5 (range 2-15) years. According to the Bado classification, 11 patients had type 1, one had type 3 and one had type 4 fracture-dislocations. For Mayo Elbow Performance Index (MEPI) scales, patients that were less than ten years old had greater mean scores. Two patients had superficial infection, one had subluxation, one had osteoarthritis, one had delayed bone union and two had rigidity at the elbow. CONCLUSION: The goals of elbow rehabilitation following Neglected Monteggia cases include restoring function by restoring motion and muscle performance; influencing scar remodeling and preventing joint contracture; and restoring or maintaining joint stability. Patients aged younger than 10 years and intervals of less than one-year, between trauma and diagnosis, as well as early and effective rehabilitation were found as important parameters regarding favorable outcomes.

Vascularized Bone Grafting in Scaphoid Nonunion: A Review of Patient-Centered Outcomes.

Background: The radiographic and clinical outcomes following vascularized bone grafting (VBG) for scaphoid nonunion have previously been reported in the literature; however, few studies report on patient-derived outcomes. The purpose of this study was to determine the effect of VBG for scaphoid nonunion on patient-derived outcomes. Methods: The MEDLINE and PubMed databases were queried for the use of VBG in scaphoid nonunion. We included studies that reported on patient-derived outcomes. We excluded studies with less than 10 patients or less than 6 months of follow-up. The primary outcomes assessed included functionality, percent and time to return to preinjury activity, postoperative pain, and patient satisfaction. Results: Twenty-six articles described the outcomes of 520 patients with an average of 19.3 patients per study. Functionality was most commonly assessed by the Mayo Modified Wrist Score and Disabilities of the Arm, Shoulder and Hand scores, which improved by 53.1% and 81.7% postoperatively, respectively. Within 16 weeks, 90.3% of patients returned to their previous occupation or sporting activity. Pain was most commonly reported using a 0 to 10 visual analog scale and improved 4-fold postoperatively. Complete satisfaction was reported by 92% of patients. The most common complications were superficial infections (1.56%), neuropathic pain (1.56%), and complex regional pain syndrome (1.25%). Conclusions: VBG for scaphoid nonunion results in the improvement of patient-derived outcomes, and high rates of return to preinjury activity levels and patient satisfaction. Multiple metrics of patient-derived outcomes were utilized by the studies in our review without a clear consensus as to which metric is most responsive and accurate.

The "Road to Union" protocol for the reconstruction of isolated complex high-energy tibial trauma.

INTRODUCTION: The purpose of this study was to describe a standardized staged approach, "The Road to Union", for the reconstruction of isolated complex tibial trauma, both acute and chronic in nature. METHODS: This retrospective study included all patients treated for complex tibial trauma at a specialized limb reconstruction centre, including acute open fracture as well as infected and aseptic non-unions. This standardized approach includes eight specific steps, employed in sequence. The time in external fixation (EFT), the external fixation index (EFI), and the distraction consolidation index (DCI) were the primary outcome measures. The relationship between EFI and DCI was assessed using Pearson's moment correlations. RESULTS: Thirty-two patients with a mean age of 34.7±14.2years were included; 12 were treated for complex open tibial fractures with bone loss, 13 for infected non-unions, and 6 for aseptic non-union. The mean bone defect was 66±32mm. The total EFT was 42.5±14.8 weeks; the EFI measured 51.9±25.3 days/cm, and the DCI measured 48.3±21.4 days/cm. Union was achieved in 29 out of 32 patients (91%), and there was a strong and significant relationship between EFI and DCI (r=0.92, p=0.0001) measurements. Pin site infections were observed in 11 patients, and 3 patients had persistent non-union. Three patients underwent delayed amputations when reconstructive procedures were unable to achieve union. CONCLUSION: The findings of this study demonstrate that a standardized staged treatment protocol of debridement, circular external fixation, soft-tissue management, distraction osteogenesis, and functional rehabilitation can result in a high rate of union in cases of complex tibial trauma, both acute and chronic in nature. LEVEL OF EVIDENCE: Level IV; case series.

Entrapment of the deep peroneal nerve and anterior tibial vessels by a spiral tibial fracture causing partial non-union: a case report.

We report a case of entrapment of the deep peroneal nerve as well as the anterior tibial artery and vein by a spiral distal tibial shaft fracture, causing partial non-union. The authors describe the utility of MRI in making the diagnosis of this post-traumatic complication, which may potentially result in a permanent neurovascular deficit and adverse functional outcome if left undetected. The importance of recognizing the distinct possibility of entrapment and injury to the deep peroneal nerve as well as the anterior tibial vessels, when managing a fracture involving the distal third of the tibial shaft is emphasized. Absence of clinical symptoms or signs of neurovascular entrapment should not deter one from performing the relevant investigations to exclude this complication, in particular when surgical fixation is being contemplated, or in the presence of a non-healing fracture.

[Old pseudoarthrosis with large bone defect of the radius treated with the Watson-Jones technique: a case report]. / Pseudarthrose ancienne avec grande perte de substance osseuse du radius traitée par la technique de Watson-Jones. À propos d'une observation.

Large bone defects in the forearm pose a challenging reconstruction problem, especially when the condition has become chronic. The Watson-Jones technique is a relatively simple procedure that sacrifices pronation-supination, but allows the forearm to be used in everyday life. Here, we describe a unique case of one-bone forearm reconstruction for a patient who had been suffering from radius non-union for several years. This reconstruction technique provided the patient with acceptable function and appearance of the arm.

Percutaneous autologous concentrated bone marrow grafting in the treatment for nonunion.

The purpose of this study was to evaluate the clinical and radiographic treatment effects of percutaneous autologous concentrated bone marrow grafting in nonunion cases and to evaluate the effectiveness of this grafting procedure. We enrolled 17 cases those had atrophic changes due to continuous nonunion for over 9 months after injury and had undergone low-intensity pulsed ultrasound treatment for more than 3 months. The site of nonunion was the femur in 10 cases, the tibia in 5 cases, the humerus in 1 case, and the ulna in 1 case. They underwent percutaneous autologous concentrated bone marrow grafting and continued low-intensity pulsed ultrasound stimulation treatment after grafting. Patients were evaluated using the visual analogue scale for pain at immediately before the procedure, 3, 6, and 12 months after grafting. Plain radiographs of the affected site were taken and evaluated about the healing of the nonunion site at each clinical evaluation. As quantitative assessment, CT scans were undertaken before the procedure and 6 months after grafting. The visual analogue scale pain score was reduced consistently after grafting in all patients. About the healing at the nonunion site, 11 and 13 cases of bone union were observed at 6 and 12 months after grafting. The mean volume of callus formation based on CT images was 4,147 (262-27,392) mm3 total between grafting and 6 months. Percutaneous autologous concentrated bone marrow grafting is an effective procedure for the treatment of patients with nonunion.

2,3 intercompartmental supraretinacular artery pedicled vascularized bone graft for scaphoid nonunions.

Scaphoid nonunion is a complex problem that may continue to exist despite conventional methods of bone grafting and internal fixation. Vascularized bone grafting has been proposed as a treatment option for scaphoid nonunions with or without avascular necrosis of the proximal pole. Zaidemberg and colleagues first introduced the dorsal distal radius graft that has gained considerable popularity in the past 2 decades. Less commonly, the 2,3 intercompartmental supraretinacular artery pedicled vascularized bone graft has been used successfully with equally promising results. It has become the graft of our choice for the treatment of scaphoid nonunions as it has a longer pedicle and is able to provide a wider arc of rotation that allows easier reach of the volar carpus. The use of rigid internal fixation with screws also permitted early wrist range of motion and shorter periods of immobilization. In this article, we describe our surgical technique of harvesting the 2,3 intercompartmental supraretinacular artery pedicled vascularized bone graft. The anatomy, indications, contraindications, and complications of treatment are also detailed.

Humeral shaft fractures: retrospective results of non-operative and operative treatment of 186 patients.

BACKGROUND: Humeral shaft fractures account for 1-3% of all fractures and 20% of the fractures involving the humerus. The aim of the current study was to compare the outcome after operative and non-operative treatment of humeral shaft fractures, by comparing the time to radiological union and the rates of delayed union and complications. METHODS: All patients aged 16 years or over treated for a humeral shaft fracture during a 5-year period were included in this retrospective analysis; periprosthetic and pathological fractures were excluded. Radiographs and medical charts were retrieved and reviewed in order to collect data on fracture classification, time to radiographic consolidation and the occurrence of adverse events. RESULTS: A total of 186 patients were included; 91 were treated non-operatively and 95 were treated operatively. Mean age was 58.7 ± 1.5 years and 57.0% were female. In 83.3% of the patients, only the humerus was affected. A fall from standing height was the most common cause of the fracture (72.0%). Consolidation time varied from a median of 11-28 weeks. The rate of radial nerve palsy in both groups was similar: 8.8% versus 9.5%. In 5.3% of the operatively treated patients, the palsy resulted from the operation. Likewise, delayed union rates were similar in both groups: 18.7% following non-operative treatment versus 18.9% following surgery. CONCLUSION: The data indicated that consolidation time and complication rates were similar after operative and non-operative treatment. A prospective randomised clinical trial comparing non-operative with operative treatment is needed in order to examine other aspects of outcome, meaning shoulder and elbow function, postoperative infection rates, trauma-related quality of life and patient satisfaction.

Arthroscopically assisted percutaneous fixation and bone grafting of a glenoid fossa fracture nonunion.

Arthroscopy is commonly used for evaluating intra-articular fracture patterns and assessing postfixation reduction; however, the use of arthroscopy for the definitive treatment of articular fracture nonunion has not been reported. This article describes a case of symptomatic glenoid fossa fracture nonunion that was successfully treated with arthroscopically assisted percutaneous screw fixation and bone grafting. A 48-year-old laborer sustained a glenoid fossa fracture following a fall from a height. An initial period of nonoperative management was attempted; however, the patient reported continued shoulder pain during his rehabilitation course. Imaging 5 months after injury showed no osseous union at the fracture. Using an arthroscopically assisted technique, percutaneous fixation and bone grafting of the nonunion with cancellous allograft was performed. Postoperatively, the patient progressed through a structured therapy program, and his pain improved. A computed tomography scan 4 months postoperatively showed osseous union at the fracture site. To the authors' knowledge, this is the first report in the literature of definitive arthroscopically assisted bone grafting and percutaneous fixation of a diarthrodial joint nonunion. Advantages of arthroscopic fixation of glenoid fossa fracture nonunion include avoiding potential axillary nerve injury and preserving the native subscapularis insertion, which may be important if subsequent procedures require access to the anterior access to the joint.

The treatment of proximal humerus nonunions in older patients with reverse shoulder arthroplasty.

INTRODUCTION: Experience with treating proximal humeral nonunions with reverse total shoulder arthroplasty is limited. We report our results. PATIENTS: Eighteen patients with proximal humeral atrophic nonunion were treated with reverse total shoulder prosthesis. There were 12 women and 6 men, with a mean age of 78.8 years (range, 75-84 years). The mean follow up after reverse arthroplasty was 28 months (range, 24-32 months). Extensive proximal humeral bone loss that was found in six cases was treated adding a proximal humeral allograft. A long humeral stem was always used. RESULTS: The mean Constant score increased from 26% preoperatively to 55% postoperatively (p <0.0001). The average anterior elevation increased from 35° to 90° (p<0.0001), abduction from 35° to 85° (p<0.0001), external rotation from 15° to 30° (p <0.0001) and internal rotation from 25° to 55° (p <0.0001). The average subjective shoulder score increased from 10% preoperatively to 50% postoperatively (p <0.0001). All but 4 patients would undergo the same procedure again if faced with the same problem. Eight patients were very satisfied, 6 satisfied and 4 unhappy with the operation. We had one case of transitory axillary nerve palsy and two cases of infection. Two prosthetic dislocations occurred; they were successfully treated by revision with a larger polyethylene glenosphere of 44 mm. CONCLUSIONS: Reverse total shoulder arthroplasty improves function and motion in patients with proximal humeral fracture sequelae. However, the rate of dislocation is high.

Successful reconstruction for complex malunions and nonunions of the tibia and femur.

BACKGROUND: Information regarding the long-term outcomes of the treatment of lower-extremity fracture malunion and nonunion is lacking. METHODS: Twenty-nine secondarily referred patients with complex malunion or nonunion of the tibia or femur, treated by a single surgeon, were followed for a median of twenty years (range, twelve to thirty-five years) after injury. The patients were referred at a median of twenty months (range, 1.5 to 360 months) postinjury and had undergone a median of three prior surgical procedures (range, zero to twenty-eight). At the time of final follow-up, patient-based outcomes, patient satisfaction, and pain were evaluated. RESULTS: All twenty-nine patients had healing following treatment of the complex malunion or nonunion of the tibia or femur and were able to bear full weight and walk one block or more. The Lower Extremity Functional Scale (LEFS) outcome tool revealed that twenty patients (69%) experienced moderate-to-severe difficulties in carrying out activities because of their lower-limb disability. The median Short Form-36 (SF-36) score was 67, with a median physical component score of 61 and a median mental component score of 71, indicating substantial impact on physical health status when compared with the norm. CONCLUSIONS: Reconstruction can be a worthwhile endeavor and should be considered for all patients with complex malunion or nonunion of the tibia or femur.

Use of homologous bone graft in the treatment of aseptic forearm nonunion.

The dyaphyseal nonunion of forearm bones is a complication that changes the normal interaction between radius and ulna, which may lead to forearm malfunction. We reviewed 14 patients treated by surgical technique included a homologous bone graft in combination with a plate. The mean age was 31 years (range, 18-45 years) at the time of surgery. Minimum follow-up was 2 years (mean, 5 years; range, 2-13 years). There were no intraoperative or postoperative complications. At last follow-up, all forearm bones had remodelled. The mean visual analogue pain scale was 1 (range, 0-4). There was a high success rate regarding forearm alignment and functional results; all patients recovered daily and working activities quickly. This surgical technique in treatment of aseptic forearm nonunion by combining homologous bone graft with a plate led to bone healing, improved forearm function, and a durable outcome with long-term follow-up.

Variable pitch headless compression screw treatment of distal phalangeal nonunions.

Nonunions of the shaft of the distal phalanx, as opposed to the tuft, are usually symptomatic enough to warrant treatment. One method that has proven successful while minimizing complications is compression fixation using variable pitch headless screws inserted percutaneously. Eighteen patients (15 males, 3 females) with a mean age of 48 years were so treated under digital block anesthesia. Seven of 18 (39%) patients were smokers. All initial injuries were crush trauma to the distal phalanx with 10/18 (56%) initially open fractures. Treatment was to 3 thumbs, 6 index fingers, 6 long, 2 ring, and 1 small. Fixation was with micro-sized variable pitch cannulated headless screws except 1 case that used 2 noncannulated threaded taper pins to compress a 3 fragment nonunion. Surgery to treat nonunion occurred at a mean of 13 weeks after the initial injury. Time to union was determined by combined clinical and radiographic assessment. The clinical criterion for union was the absence of pain at the nonunion site with application of maximum pinch pressure to the ipsilateral thumb or finger. The radiographic criteria for union was bridging trabeculae seen on 2 or more cortices and the absence of any signs of hardware loosening, using standard posteroanterior and lateral projections. All 18 patients went on to achieve union at a mean of 9 (±2.8) weeks after surgery. Complications specifically sought out but not identified were infection, loss of reduction, further comminution, hardware loosening, secondary surgery, nail deformity, and continued pain precluding successful pinch.

Treatment of femoral diaphyseal non-unions: our experience.

Despite the continuous advances of surgical solutions, still 1-7% of fractures develop non-unions. The delays in fracture healing increase the period of incapacity of the patient with major consequences, on the psychological and functional recovery, but also on the direct and indirect health-related costs. In particular, femoral diaphyseal non-unions are often characterised by a challenging and long-lasting period of healing. The clinician treating these complex cases has to consider amongst other parameters, the condition of the soft tissue envelope, the adequacy of any pre-existing fixation, the alignment and length of the affected limb, the potential presence of an infection, as well as the general condition of the patient. Open reduction and plate fixation of femoral diaphyseal non-unions offers a valid alternative of stabilisation and if applied to carefully selected cases, can give optimal results.

Anterior plating as a surgical alternative in the treatment of humeral shaft non-union.

This study included 15 patients with humeral shaft fractures who had no clinical, radiological or bone scan signs of healing after eight months. The patients were followed for a mean of 35.8 months. No patient was lost to follow-up. Anterior plating of humeral shaft nonunion via an anterior approach was performed using a straight plate and compression for well-vascularised non-unions and wave plating with a tricortical graft for poorly vascularised non-unions. All non-unions healed within 6-18 weeks (mean, nine weeks) without local complication. One patient had a mild decrease in elbow and shoulder range of motion. No neurovascular injury was observed. Anterior plating is a simple, safe and effective treatment for humeral shaft non-union. As this approach avoids the need for radial nerve visualisation and extensive soft-tissue dissection, and the healing time is similar to that of other methods, we suggest this treatment as an alternative option.

Predictors of patient and surgeon satisfaction after orthopaedic trauma.

INTRODUCTION: Patient satisfaction has only recently gained attention as an outcome measure in orthopaedics, where it has been reported for joint replacement surgery. Little has been published regarding predictors of patient satisfaction in orthopaedic trauma. This study aims to explore the predictors of patient satisfaction, and of surgeon satisfaction, after orthopaedic trauma. MATERIALS AND METHODS: Adult patients admitted to hospital with fractures after motor vehicle trauma were surveyed on admission, and at six months. Demographic, injury, socio-economic and compensation-related factors were measured. The two outcomes were satisfaction with progress of the injury, and satisfaction with recovery. The treating surgeons were also surveyed at six months to determine surgeon satisfaction with progress, and recovery (using the same questions), and the presence or absence of fracture union and any complications. Multivariate analysis was used to determine significant predictors of satisfaction for both groups, and satisfaction rates were compared between surgeons and patients. RESULTS: Of 306 patients recruited, 232 (75.8%) returned completed questionnaires, but only 141 (46.1%) surgeons responded. Patients rated their satisfaction with progress and recovery as 74.6% and 44.4%, respectively, whereas surgeon-rated satisfaction with progress and recovery was significantly higher, at 88.0% and 66.7%, respectively (p<0.0001). Significant predictors of patient dissatisfaction were: blaming others for the injury, being female, and using a lawyer. Patient-rated satisfaction was not significantly associated with objective injury or treatment factors. The only significant predictor of surgeon dissatisfaction was fracture non-union. CONCLUSIONS: Orthopaedic surgeons overestimated the progress of the injury and the level of recovery compared to patients' own ratings. Surgeons' ratings were influenced by objective, treatment-related factors, whereas patients' ratings were not. Measures of outcome commonly used by orthopaedic surgeons, such as fracture union, do not predict patient satisfaction.

Nonunion of the distal radius.

Distal radius nonunion is either more common or more commonly recognized. The success of operative treatment to gain union seems to have improved along with improvements in operative fixation of fractures of the distal radius. Operative treatment to gain union or arthrodese the wrist can improve function and comfort with relatively few complications.
