Abstract
Objective To analyze the correlation between postoperative complications and combined deflection angle classification adduction type (CDAC-ADT) of femoral neck fractures after cannulated screw internal fixation. Methods The clinical data of 121 patients with CDAC-ADT femoral neck fracture admitted between January 2018 and December 2021 and met the selected criteria were retrospectively analyzed. There were 69 males and 52 females, the age ranged from 19 to 79 years (mean, 48.1 years). The causes of injury included 52 cases of traffic accident, 24 cases of falling from height, and 45 cases of fall. The time from injury to operation ranged from 2 to 12 days, with an average of 6.0 days. Among them, there were 18 cases of CDAC-ADT type Ⅰ, 46 cases of type Ⅱ, and 57 cases of type Ⅲ; 6 cases of Garden type Ⅱ, 103 cases of type Ⅲ, and 12 cases of type Ⅳ; and according to the location of the fracture line, there were 26 cases of subcapitate type, 88 cases of transcervical type, and 7 cases of basal type. All patients were treated with cannulated screw internal fixation. The occurrence of complications (including internal fixation failure, fracture nonunion, and osteonecrosis of the femoral head) was recorded, and the correlation between complications and CDAC-ADT typing, Garden typing, and fracture line location were analyzed. Results The patients were followed up 8-44 months, with a mean of 24.9 months. There were 10 cases of internal fixation failure, 7 cases of fracture nonunion, and 30 cases of osteonecrosis of the femoral head after operation. Correlation analysis showed that patients' CDAC-ADT typing was significantly correlated with the overall incidence of complication and the incidence of internal fixation failure, fracture nonunion, and osteonecrosis of the femoral head ( P<0.05), and the Pearson coefficient of contingency were 0.435, 0.251, 0.254, and 0.241, respectively. Garden typing did not correlate with the overall incidence of complication and the incidence of internal fixation failure and fracture nonunion ( P>0.05), but correlated with the incidence of osteonecrosis of the femoral head ( P<0.05), and the Pearson coefficient of contingency was 0.251. Fracture line position typing had no correlation with the overall incidence of complication and the incidence of internal fixation failure, fracture nonunion, and osteonecrosis of the femoral head ( P>0.05). Conclusion CDAC-ADT typing has obvious correlation with postoperative complications of femoral neck fracture and can be used to predict complications of femoral neck fracture.

Compressive buttress compared with off-axial screw fixation for vertical femoral neck fractures in young adults: a prospective, randomized controlled trial. J Orthop Surg Res 2024; 19:42. [PMID: 38184587 PMCID: PMC10771671 DOI: 10.1186/s13018-023-04493-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 12/19/2023] [Indexed: 01/08/2024] Open
Abstract
BACKGROUND To compare the clinical outcomes of compressive buttress screw (CBS) fixation, a novel screw fixation strategy, to off-axial screw fixation (off-axial partial threaded cannulated screw, OPTCS) for vertical femoral neck fractures (FNFs) in young adults. METHODS A total of 146 adults younger than 55 years old with high-energy Pauwels type III FNFs were randomized to receive CBS fixation or OPTCS fixation. Primary outcomes were complication rates, including fixation failure, fracture nonunion, and avascular necrosis of the femoral head (ANFH) at 24 months after treatment. Fixation loosening, femoral neck shortening and varus collapse, patient function and quality of life using the Harris hip score (HHS), and EuroQol-5 dimensional-5 levels (EQ-5D-5L) questionnaire (including EQ-5D-5L and EQ-VAS) were assessed as secondary outcomes at 24 months. RESULTS CBS and OPTCS fixation groups were similar with regard to demographics at baseline. At 24 months, patients in the CBS fixation cohort had a significantly lower rate of fixation failure (10.5% vs. 25.0%, p = 0.041) and fracture nonunion (1.8% vs. 18.3%, p = 0.003) compared with patients who received OPTCS fixation. There was no difference in rate of ANFH (7.0% vs. 11.7%, p = 0.389) between groups. Additionally, patients managed with CBS fixation showed significantly less fixation loosening (19.3% vs. 58.3%, p < 0.001), less severe femoral neck shortening and varus collapse (10.5% vs. 25.0%, p = 0.007), higher HHS (93 vs. 83, p = 0.001) and more excellent grade (68.4% vs. 36.7%, p = 0.008), higher EQ-5D-5L (0.814 vs, 0.581, p < 0.001) and EQ-VAS (85 vs. 80, p = 0.002). CONCLUSION CBS screw fixation confers significantly lower complication rate in addition to higher functional and quality of life outcomes for young adults with high-energy FNF compared with OPTCS fixation. TRIAL REGISTRATION This prospective, randomized controlled trial was approved by the institutional review board of our center, Ethics Committee of Shanghai sixth people's Hospital, and registered at www.chictr.org.cn (Approval Number: ChiCTR1900026283; Registered 29 September 2019-Retrospectively registered, https://www.chictr.org.cn/showproj.html?proj=43164 ).

Abstract
The intramedullary total femoral reconstruction (ITFR) was used successfully in a 62-year-old patient with myxoid liposarcoma of the thigh and post-radiation fracture nonunion of the proximal femur and osteonecrosis of the ipsilateral knee. This described technique offers the advantage of a less invasive prosthesis insertion, preservation of the surrounding muscle attachments, better functional outcomes, and lower complication rates. Total femoral reconstruction using ITFR, preserving the femoral diaphysis, could be an option to address concomitant hip and knee defects, especially in patients with poor soft tissue quality.

Abstract
BACKGROUND Dens fractures are an increasingly common injury, yet their epidemiology and its implications remain underexamined. METHODS We retrospectively analyzed all traumatic dens fracture patients managed at our institution over a 10-year period, examining demographic, clinical, and outcomes data. Patient subsets were compared across these parameters. RESULTS Among 303 traumatic dens fracture patients, we observed a bimodal age distribution with a strong goodness of fit centered at age 22.3 ± 5.7 (R = 0.8781) and at 77.7 ± 13.9 (R = 0.9686). A population pyramid demonstrated a bimodal distribution among male patients, but not female patients, which was confirmed with a strong goodness of fit for male patient subpopulations age <35 (R = 0.9791) and age ≥35 (R = 0.8843), but a weaker fit for a second female subpopulation age <35. Both age groups were equally likely to undergo surgery. Patients younger than age 35 were more likely to be male (82.4% vs. 46.9%, odds ratio [OR] = 5.29 [1.54, 17.57], P = 0.0052), have motor vehicle collision as their mechanism of injury (64.7% vs. 14.1%, OR = 11.18 [3.77, 31.77], P < 0.0001), and to have a severe trauma injury severity score (17.6% vs. 2.9%, OR = 7.23 [1.88, 28.88], P = 0.0198). Nevertheless, patients age <35 were less likely to have fracture nonunion at follow (18.2% vs. 53.7%, OR = 0.19 [0.041, 0.76], P = 0.0288). CONCLUSIONS The dens fracture patient population comprises 2 subpopulations, distinguished by differences in age, sex, injury mechanism and severity, and outcome, with male dens fracture patients demonstrating a bimodal age distribution. Young, male patients were more likely to have high-energy injury mechanisms leading to severe trauma, yet were less likely to have fracture nonunion at follow-up.

Abstract
OBJECTIVE To analyze and compare the clinical efficacy of F-shaped hollow screw and traditional inverted triangle three parallel screws in the treatment of young and middle-aged Pauwels type Ⅲ femoral neck fracture. METHODS From January 2017 to January 2020, 38 patients with Pauwels type Ⅲ femoral neck fracture were treated. They were divided into two groups according to different screw placement methods. Among them, 18 patients in group A were fixed with F-shaped hollow screw, including 12 males and 6 females, aged 37 to 55 years, the time from injury to operation was 1 to 3 days. Other 20 cases in group B were fixed with 3 parallel screws in traditional inverted triangle, including 12 males and 8 females, aged 35 to 55 years. The time from injury to operation was 1 to 3 days. The fracture nonunion, femoral head necrosis, femoral neck shortening, hollow screw withdrawal, hip function Harris score and visual analogue scale(VAS) of pain were compared between the two groups. RESULTS All patients were followed up for 15 to 31 months. There was no significant difference in fracture nonunion, femoral neck shortening and femoral head necrosis between two groups(P>0.05). There was significant difference in screw withdrawal between two groups(P<0.05). There was no significant difference in hip Harris score and VAS between the two groups at 12 months after operation(P>0.05). CONCLUSION The short-term and medium-term effects of F-shaped and traditional inverted triangle three parallel screws in the treatment of young and middle-aged Pauwels Ⅲ femoral neck fractures are similar, but the nail withdrawal rate of F-shaped hollow screw is low.

Abstract
SUMMARY Nonunited fractures of the femoral shaft and distal femur are usually successfully addressed with stabilization with or without autogenous bone grafting. For the small subset of these problems that prove recalcitrant to front-line treatment, a pedicled medial femoral condyle (MFC) bone flap can provide a source of vascularized autograft with minimal donor site morbidity. The MFC has gained recent widespread adoption as a free vascularized bone transfer, and here, we present a surgical technique and retrospective analysis of patients treated with a pedicled MFC technique. This serves as a useful treatment option for these difficult problems and may be especially helpful in low resource environments or where microsurgical anastomosis is not feasible.

Abstract
OBJECTIVES To evaluate the differences in patient outcomes after operative or nonoperative treatment of displaced, type II distal clavicle fractures. DESIGN Multicenter, prospective, randomized controlled trial. SETTING Level I trauma centers. PATIENTS/PARTICIPANTS Patients with completely displaced type II distal clavicle fractures were included. Fifty-seven patients were randomized: 27 to the operative group and 30 to the nonoperative group. INTERVENTION Patients randomized to nonoperative care received a standard shoulder sling, followed by pendulum or gentle range of motion shoulder exercises at any time as directed by the attending surgeon. Patients randomized to the operative group received plate fixation with a precontoured distal clavicular plate or a "hook" plate within 28 days from injury. MAIN OUTCOME MEASURE Disabilities of the Arm, Shoulder and Hand scores at 1 year. RESULTS There were no between-group differences in Disabilities of the Arm, Shoulder and Hand or Constant scores at 1 year. More patients in the operative group went on to union (95% vs. 64%, P = 0.02) within 1 year. Twelve patients in the operative group underwent a second operation for implant removal (12/27, 44%). In the nonoperative group, 6 patients (6/30, 20%) subsequently underwent 8 operative procedures. CONCLUSION Although this study failed to demonstrate a difference in functional outcomes between operative and nonoperative treatment of Neer type II distal clavicle fractures, nonoperative management led to more complications including a moderate rate of nonunion, which often required secondary surgery to correct, a higher rate of early dissatisfaction with shoulder appearance, and a delayed return to activities in the first 6 months. Operative management provided a safe and reliable treatment option with few complications, but often required secondary implant removal, especially with hook plate fixation. LEVEL OF EVIDENCE Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Abstract
OBJECTIVE The aim of this study was to compare the histological results of Accordion Maneuver (AM) with Compression Technique Alone (CA) in the treatment of atrophic fracture nonunion in a rabbit model. METHODS The study was performed on 91 male New Zealand rabbits aged six months, weighing 3.1 to 3.6 kg. The standardized models of atrophic nonunion with a 3-mm fracture were created in the tibias of rats. For the histomorphological study, 22 rabbits were randomly selected and sacrificed. The remaining 69 rabbits were divided into two groups based on the treatment technique: Group AM (n = 36) and Group CA (n = 33). The group AM was further randomly divided into four subgroups based on the amplitude and interval parameters: subgroup A1B1 (0 day, 4 mm; n = 9), subgroup A1B2 (0 day, 8 mm; n = 7), subgroup A2B1 (6 days, 4 mm; n = 10), and subgroup A2B2 (6 days, 8 mm; n = 10). A monolateral external fixator was employed in each group. Animals were sacrificed 6 weeks after the treatment, and bony healing was assessed both radiologically and histologically. The efficiency of bony healing was assessed using the bone content index, bone mineral density, and bone volume fraction indexes. RESULTS In X-ray and micro-computed tomography assessments, periosteal reaction was detected at the fracture site in all specimens. In group CA, sclerosis was observed at the ends of the fragments. Bony absorption, nonunion, and a little amount of island-like high density were also observed at the nonunion site. Among AM subgroups, sparse callus-like bone formation in A1B1 subgroup and a high density of callus connecting most parts of the gap and large amount of periosteal callus formation in A1B1 subgroup were observed. In A2B2 subgroup, the cortex was initially connected. No gap was observed, and the medullary cavity was recanalized. In histological analyses, the intermission of 0 day at rate of 8 mm was of the highest level of bony regeneration, and the intermission of 6 days at the rate of 4 mm was of the lowest level of bony regeneration (P < 0.05). CONCLUSION Based on the radiological and histological results obtained from the present study, AM seems to be more effective than CA in treating atrophic nonunion. AM can shorten the period of treatment. The interval of 0 day and an amplitude of 8 mm may be more proper for AM.

Abstract
Treatment of atrophic non-unions, especially in long bones is a challenging problem in orthopedic surgery due to the high revision and failure rate after surgical intervention. Subsequently, there is a certain need for a supportive treatment option besides surgical treatment. In our previous study we gained first insights into the dynamic processes of atrophic non-union formation and observed a prolonged inflammatory reaction with upregulated TNF-α levels and bone resorption. In this study we aimed to improve bone regeneration of atrophic non-unions via TNF-α modulation in a previously established murine femoral segmental defect model. Animals that developed atrophic non-unions of the femur after 5 and 10 weeks were treated systemically for 10 and 5 weeks with Etanercept, a soluble TNF-α antibody. μCT scans and histology revealed bony bridging of the fracture gap in the treatment group, while bone formation in control animals without treatment was not evident. Moreover, osteoclasts were markedly decreased via modulation of the RANKL/OPG axis due to Etanercept treatment. Additionally, immunomodulatory effects via Etanercept could be observed as further inflammatory agents, such as TGF-β, IL6, MMP9 and 13 were decreased in both treatment groups. This study is the first showing beneficial effects of Etanercept treatment on bone regeneration of atrophic non-union formation. Moreover, the results of this study provide a new and promising therapeutic option which might reduce the failure rate of revision surgeries of atrophic non-unions.

Abstract
PURPOSE The ideal treatment of non-united and neglected fracture neck femur in the young adult still remains unclear and is characterized by many biological and biomechanical challenges. METHODS Twenty-one patients with non-united or neglected fracture neck femur aged between 19 and 50 years were treated by a novel subtrochanteric valgus osteotomy and were followed up for a mean of 26.7 months. Patients were assessed by radiological parameters, the Harris Hip Score, Oxford Knee Score, and Askin Bryan Criteria to categorize the overall outcome of the patients at 24 months. Other outcome measures included the occurrence of AVN, adductor lever arm, leg length discrepancy, and mechanical implant failure. RESULTS All patients treated with the SALVA osteotomy consolidated and displayed a marked improvement of functional and radiological outcome measures. Nevertheless, there were 2 mechanical failures in patients with marked osteopenia and three developed AVN. CONCLUSIONS In patients with un-united/neglected fracture neck femur, SALVA osteotomy appears to be reliable and reproducible. It also restores the abductor lever arm and improves the leg length discrepancy. Technically less demanding conversion to arthroplasty remains still possible prospectively.

Abstract
The pseudoarthrosis (PSA) of scaphoid leads to alteration in load transfer in the wrist joint. Its treatment aims to achieve consolidation to improve clinical complaints and prevent post-traumatic arthritis. The indication for using vascularized bone grafts is still controversial. This prospective comparative study aimed to compare consolidation rate and time to healing of scaphoid PSA treated by volar distal radius vascularized bone graft vs non-vascularized iliac bone graft. Nine patients underwent vascularized grafting of scaphoid PSA. These patients were compared to a control group consisting of twelve patients treated with iliac crest-free bone graft. PSA consolidation was obtained in 8 of 9 patients (88%) and 9 of 12 patients (75%) in the study and control group, respectively. The difference in consolidation rate was not significant. Two of three patients with AVN of the proximal pole in the study group (66%) went to consolidation. In the control group no patient with AVN obtained bone consolidation. This difference almost reached statistical significance (p = 0.083). The mean time to consolidation was 8.6 weeks (range 8-11) and 11.7 weeks (range 10-16), respectively, in the study and control group. This difference was significant (p < 0.05). In conclusion, the distal radius vascularized graft led to satisfactory consolidation rate of PSA in the current study, even in cases of AVN of the proximal pole. Moreover, the vascularized bone graft resulted in shorter healing time compared to the non-vascularized graft.

Abstract
PURPOSE To describe the radiographic, functional, and patient-reported outcomes (PROs) of medial femoral trochlea (MFT) osteochondral free flap reconstruction of the proximal scaphoid at approximately 2 years follow-up. METHODS Eleven patients who underwent MFT reconstruction of the proximal scaphoid returned for clinical examination, radiographs, and completion of PROs questionnaires. For another 10 patients who were unable to return, data were gathered remotely or from the medical record. RESULTS Mean radiographic follow-up was 2.0 years and mean examination follow-up ranged from 2.6 to 2.8 years. Mean follow-up for several PROs ranged from 2.8 to 2.9 years. On average, carpal collapse did not progress, and radiolunate angle was significantly improved by 9.5°. Wrist flexion (41.6°; -6%) and extension (43.8°; -7%) were only slightly changed, and dominance-corrected postoperative pinch and grip strength were 77% and 72% of the uninjured side, respectively. Mean postoperative Disabilities of the Arm, Shoulder, and Hand (DASH) score was 10.7. In patients with both pre- and postoperative scores available, DASH significantly improved by 15 points. Knee donor-site morbidity was measured on the Knee Injury and Osteoarthritis Outcome Score (KOOS)-Sports and Recreation and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scales. The Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health, Physical Function, Pain Intensity, Pain Interference, and Pain Behavior scores reflected good postoperative patient health and function and low pain levels. Higher body mass index (BMI) was found to be predictive of inferior lower extremity and global PROs. CONCLUSIONS An MFT reconstruction of proximal scaphoid nonunion has the potential to restore normal functional radiocarpal anatomy, improve function, and relieve pain without causing wrist stiffness or weakness. Donor-site morbidity has been further delineated in this study. Caution is warranted when considering this procedure in patients with elevated BMI because they may be at increased risk for donor-site morbidity. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Scaphoid fractures are common and notorious for their troublesome healing. The aim of this review is to reevaluate the current best evidence for the diagnosis, classification, and treatment of scaphoid fractures and nonunions. MRI and CT are used to establish a "definitive diagnosis" with comparable diagnostic accuracy although neither is 100% specific. Current classifications cannot reliably predict union or outcomes; hence, a descriptive analysis of fracture location, type, and extent of displacement remains most useful. Treatment of a nondisplaced scaphoid waist fracture remains an individualized decision based on shared decision-making. Open reduction and internal fixation may be preferred when fracture displacement exceeds 1 mm, and the fracture is irreducible by closed or percutaneous means. For unstable nonunions with carpal instability, either non-vascularized cancellous graft with stable internal fixation or corticocancellous wedge grafts will provide a high rate of union and restoration of carpal alignment. For nonunions characterized with osteonecrosis of the proximal pole, vascularized bone grafting can achieve a higher rate of union.

[Ilizarov external fixation without bone graft for atrophic femoral shaft nonunion]. ZHONGGUO XIU FU CHONG JIAN WAI KE ZA ZHI = ZHONGGUO XIUFU CHONGJIAN WAIKE ZAZHI = CHINESE JOURNAL OF REPARATIVE AND RECONSTRUCTIVE SURGERY 2019; 33:940-946. [PMID: 31407550 PMCID: PMC8337899 DOI: 10.7507/1002-1892.201902076] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 07/01/2019] [Indexed: 12/29/2022]
Abstract
OBJECTIVE To explore the effectiveness of Ilizarov external fixation without bone graft in the treatment of atrophic femoral shaft nonunion. METHODS The clinical data of 12 patients with atrophic femoral shaft nonunion admitted between October 2010 and January 2017 were retrospectively analyzed. There were 8 males and 4 females, aged from 24 to 61 years, with an average age of 41.7 years. The nonunion sites located in the middle and upper femur in 7 cases and in the distal femur or supracondylar in 5 cases. The disease duration ranged from 1 to 9 years, with an average of 3.7 years. Previous operations ranged from 1 to 9 times, with an average of 2.8 times. The original fixator was removed, the fracture end of nonunion was debrided, and Ilizarov external fixator was installed. In patients with the length of bone defect less than 4 cm, direct compression fixation was performed during operation; in patients with limb shortening more than 2.5 cm, proximal femoral osteotomy and bone lengthening components were required to prepare limb lengthening after operation; all patients did not receive bone graft. The wearing time of external fixator, clinical bone healing time of nonunion fracture end, and complications were recorded. The effectiveness was evaluated by Paley's nonunion evaluation criteria. RESULTS All patients were followed up 24-50 months, with an average of 30 months. Bony union was achieved in all 12 cases with a healing time of 6.0-23.5 months (mean, 11.5 months). The wearing time of external fixator ranged from 7 to 25 months, with an average of 13.5 months. At last follow-up, according to Paley's nonunion evaluation criteria, the results were excellent in 6 cases, good in 4 cases, and fair in 2 cases, with an excellent and good rate of 83.3%. Sagittal angulation deformity of femur more than 7° occurred in 4 cases, with no significant effect on knee extension function, and no special treatment such as osteotomy was performed. Two patients had shorter limbs (>2.5 cm) after operation and were replaced by high shoes; 4 patients with trans-knee fixation lost knee joint mobility of 10-30° after operation; 10 cases of needle tract infection occurred, of which 4 cases with infection and loosening of fixed needle were replaced and re-fixed after needle extraction, the remaining 6 cases of infection without loosening of fixed needle were controlled by local dressing change, needle nursing, and oral cephalosporin anti-inflammatory drugs. No complications such as deep infection and vascular nerve injury occurred. CONCLUSION Ilizarov external fixation has a high healing rate for atrophic femoral shaft nonunion, which is relatively minimally invasive and can avoid bone grafting. Its preliminary effectiveness is exact, and it is also effective for patients who have experienced multiple failed operations. It is necessary to pay attention to the nursing and rehabilitation training after external fixation.

Intramedullary screw fixation for simple displaced olecranon fractures. Eur J Trauma Emerg Surg 2019; 46:83-89. [PMID: 30879100 PMCID: PMC7026218 DOI: 10.1007/s00068-019-01114-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2018] [Accepted: 03/11/2019] [Indexed: 01/11/2023]
Abstract
Purpose Olecranon fractures are common and typically require surgical fixation due to displacement generated by the pull of the triceps muscle. The most common techniques for repairing olecranon fractures are tension-band wiring or plate fixation, but these methods are associated with high rates of implant-related soft-tissue irritation. Another treatment option is fixation with an intramedullary screw, but less is known about surgical results using this strategy. Thus, the purpose of this study was to report the clinical and functional outcomes of olecranon fractures treated with an intramedullary cannulated screw. Methods We identified 15 patients (average age at index procedure 44 years, range 16–83) with a Mayo type I or IIA olecranon fracture who were treated with an intramedullary cannulated screw at a single level 2 trauma center between 2012 and 2017. The medical record was reviewed to assess radiographic union, postoperative range of motion and complications (including hardware removal). Patient-reported outcome was evaluated using the Disabilities of the Arm, Shoulder and Hand (DASH) score. Average follow-up was 22 months (range 8–36 months). Results By the 6th month post-operative visit, 14 patients had complete union of their fracture and 1 patient had an asymptomatic non-union that did not require further intervention. Average flexion was 145° (range 135–160) and the average extension lag was 11° (range 0–30). Implants were removed in 5 patients due to soft-tissue irritation. Average DASH score (± standard deviation) by final follow-up was 16 ± 10. Conclusions Fixation of simple olecranon fractures with an intramedullary screw is a safe and easy fixation method in young patients, leading to good functional and radiological results. Compared to available data, less hardware removal is necessary than with tension-band wiring or plate fixation.

Abstract
Nonunion of the scaphoid is a severe complication of often insufficiently treated scaphoid fractures or those which have been diagnosed too late. The treatment of scaphoid nonunion is challenging und should be performed by experienced hand surgeons. The anatomical shape, the retrograde blood supply and the biomechanics of the scaphoid complicate the healing process. A delayed union or nonunion of the fractured scaphoid leads to persistent pain, restricted mobility and degenerative changes of carpal bones and wrist. The goal of treatment is bony healing of the pseudarthrosis with reconstruction of the anatomical shape and restoration of the axial alignment of the scaphoid. A prerequisite is the right choice of the different treatment options available. Fundamental to this is a careful pretherapeutic assessment as well as an individual classification of the pathological alterations and the morphological features of the nonunion. For this purpose, radiological cross-sectional imaging by means of computed tomography is essential. There is no consensus in the literature about the treatment of scaphoid nonunion. The available data do not enable the establishment of a superior treatment procedure. The most common surgical procedure used to treat scaphoid nonunion is autologous bone grafting combined with screw fixation. This article provides an up to date overview of the management and standard procedures for the primary treatment of scaphoid nonunion without a circulatory disorder.

Abstract
With the increasing incidence of fractures now, and in the future, the absolute number of bone-healing complications such as nonunion development will also increase. Next to fracture-dependent factors such as large bone loss volumes and inadequate stabilization, the nutritional state of these patients is a major influential factor for the fracture repair process. In this review, we will focus on the influence of protein/amino acid malnutrition and its influence on fracture healing. Mainly, the arginine-citrulline-nitric oxide metabolism is of importance since it can affect fracture healing via several precursors of collagen formation, and through nitric oxide synthases it has influences on the bio-molecular inflammatory responses and the local capillary growth and circulation.

Abstract
Arthroscopic reduction with osteosynthesis using bone grafting has become a successful alternative to open techniques for the treatment of chronically unstable scaphoid nonunions. Several studies have demonstrated that arthroscopic techniques are safe and reproducible in addition to causing less soft tissue damage and providing promising short- and mid-term results. However, these techniques have limitations in restoring normal carpal alignment, especially in patients with unstable scaphoid nonunion and carpal collapse deformities, although this does not affect the recovery of clinical function. Therefore, the practical goal of arthroscopic technique should be kept in mind when treating unstable scaphoid nonunions.

Abstract
Objective To explore the effectiveness difference between titanium elastic intramedullary nail internal fixation and bone plate internal fixation in the treatment of adult Galeazzi fracture. Methods Ninety-seven patients of Galeazzi fracture according with the selection criteria were divided into 2 groups by prospective cohort study, who were admitted between January 2012 and November 2015. In the patients, 59 were treated with open reduction and bone plate internal fixation (plate group), and 38 with titanium elastic intramedullary nail internal fixation (minimally invasive group). There was no significant difference in the gender, age, cause of injury, fracture site, type of fracture, and time from injury to operation between 2 groups ( P>0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were recorded and compared between 2 groups, and the forearm function was evaluated by Anderson score. Results All the patients were followed up 12-23 months (mean, 17 months). The operation time, intraoperative blood loss, fracture healing time of minimally invasive group were significantly less than those in plate group ( P<0.05). There were 1 case of fracture nonunion, 1 case of wound infection in plate group, and 1 case of nail tail slight infection in minimally invasive group, which were all cured after the corresponding treatment. The remaining patients had good fracture healing, and no vascular injury, internal fixation failure, deep infection, or other complications occurred. According to Anderson score at 12 months after operation, the forearm function results were excellent in 46 cases, good in 12 cases, and poor in 1 case, with an excellent and good rate of 98.3% in plate group; and the results were excellent in 26 cases, good in 11 cases, and poor in 1 case, with an excellent and good rate of 97.4% in minimally invasive group; showing no significant difference ( χ2=0.10, P=0.75). Conclusion Minimally invasive fixation with titanium elastic nail has such advantages as small damage, quick recovery, no skin scarring, etc. As long as the correct indication is selected, minimally invasive titanium intramedullary nail internal fixation of Galeazzi fractures can also get good effectiveness.

Abstract
Fracture injuries are highly prevalent worldwide, with treatment of problematic fractures causing a significant burden on the U.S. healthcare system. Physicians typically monitor fracture healing by conducting physical examinations and taking radiographic images. However, nonunions currently take over 6 months to be diagnosed because these techniques are not sensitive enough to adequately assess fracture union. In this study, we display the utility of impedance spectroscopy to track different healing rates in a pilot study of an in vivo mouse tibia fracture model. We have developed small (56 μm) sensors and implanted them in an externally-stabilized fracture for twice-weekly measurement. We found that impedance magnitude increases steadily over time in healing mice but stalls in non-healing mice, and phase angle displays frequency-dependent behavior that also reflects the extent of healing at the fracture site. Our results demonstrate that impedance can track differences in healing rates early on, highlighting the potential of this technique as a method for early detection of fracture nonunion.

Abstract
INTRODUCTION Bisphosphonate therapy (BT) is used commonly in the management of osteoporosis. A systematic review was conducted investigating delayed union of lower limb, long bone fractures in patients on BT. We specifically assessed whether BT increases the risk of delayed union or non-union in lower limb, long bone fractures. METHODS A literature search was conducted in the PubMed and Embase™ on 4 November 2014. Articles that investigated lower limb fractures, history of BT and fracture union were included in the review. RESULTS A total of 9,809 papers were retrieved and 14 were deemed suitable for this review. The mean time to union in patients on BT was 8.5 months. A longer time to union was reported in a study investigating BT users versus controls (6.5 vs 4.8 months respectively). The mean rate of delayed or non-union for BT associated atypical fractures was 20% per fracture. Specifically in one study, delayed union was more common in the cohort with more than three years of BT (67%) than in the group with less than three years of BT (26%). Surgical fixation was associated with improved outcomes compared with non-operative management. CONCLUSIONS BT has been described to be associated with multiple adverse outcomes related to atypical fractures. Current evidence recommends operative management for this patient group. Further investigation is required to evaluate the exact effects of BT on lower limb fractures, in particular typical femoral fractures.

Abstract
Old fracture generally refers to fractures for more than 3 weeks, and complications caused by delayed treatment or therapy: delayed union, malunion and nonunion of fractures. Delayed union means that fracture healing is not taking place within the expected time, but the definition of fracture nonunion is controversy. Delayed union and nonunion of fractures are caused by a variety of factors, unstable and blood supply of destroy are considered the most important factors. Because of substantial suffering about patients living, working and economics caused by delayed union and nonunion, early intervention is necessary. Treatment includes conservative and operative. Mechanical stimulation, physical treatment and bio-stimulation have been proven to promote healing of fractures, autogenous cancellous bone graft combined with strong fixation is the gold standard for surgery. Malunion means a consolidation of a fracture in a position of deformity and malalignment. Deformities are described in terms of abnormalities of length, angulation, rotation, and translation. The treatment of malunion is a lengthy and complex process and the main purpose is to relieve pain, restoring alignment and function.

Abstract
To compare clinical and radiographic outcomes of medial epicondylar fractures treated operatively to those treated nonoperatively, 30 patients with 31 fractures were divided into three groups: (a) nondisplaced, six treated nonoperatively; (b) incarcerated fragment, four with operative treatment; and (c) displaced but not incarcerated, 21 fractures, 14 treated operatively and seven nonoperatively. Clinical outcomes were assessed with follow-up examination and the Japanese Orthopaedic Association elbow assessment score. Average elbow scores were 98 in nondisplaced fractures, 94 with an incarcerated fragment, 95 in displaced fractures treated operatively, and 94 in displaced fractures treated nonoperatively. The only nonunion was in a fracture with an incarcerated fragment. Both operative and nonoperative treatment produced good outcome scores in displaced but not incarcerated fractures, but radiographic deformity and instability were more frequent in those treated nonoperatively.

Abstract
OBJECTIVE To investigate the method and effectiveness of operative treatment of Dubberley type 3B capitulum-trochlea fractures. METHODS Between January 2009 and December 2012, 8 cases of Dubberley type 3B capitulum- trochlea fractures were treated. There were 2 males and 6 females with an average age of 55 years (range, 43-65 years). The injury was caused by falling in 6 cases, electric bicycle accident in 1 case, and traffic accident in 1 case. All fractures were fresh and closed injury. No neural or vascular injury was found. The time between injury and operation was 3-15 days (mean, 5.9 days). Olecranon osteotomy was performed by a posterior midline skin incision of the elbow; 3.0 mm Herbert compression screws placed from posterior to anterior, 2.4 mm L shape locking compression plate designed for distal radius or 2.7 mm anatomical locking compression plate designed for distal humerus and 1.0 mm Kirschner wires or 3.0 mm Herbert screw for the transverse and coronal plane in the subchondral of anterior articular surface were used for fixation; and the lateral and medial collateral ligaments were repaired. RESULTS All incisions healed by first intention. The patients were followed up 12-18 months (mean, 14.5 months). The X-ray films showed that fracture healing was achieved at 12-24 weeks (mean, 15 weeks) in 7 cases. Fracture nonunion and partial bone resorption in the capitellum were observed in 1 case. No failure of internal fixation, ulnohumeral joint instability, or traumatic arthritis occurred. At last follow-up, the range of motion of injured elbow was 0-40° in extension (mean 25.0°), 100-135° in flexion (mean, 116.3°), 60-70° in pronation (mean, 61.3°), and 80-90° in supination (mean, 81.3°). The elbow function score was 64-96 (mean, 81.1) according to the Broberg-Morrey evaluation criteria; the results were excellent in 2 cases, good in 4 cases, and fair in 2 cases with an excellent and good rate of 75%. The visual analogue scale (VAS) score was 0-3 (mean, 1). CONCLUSION For Dubbelley type 3B capitulum-trochlea fractures, an early anatomic reconstruction of capitellar and trochlea, repair of the medial and lateral collateral ligament, and early active mobilization can obtain good functional

Abstract
BACKGROUND The morbidity and socioeconomic costs of fractures are considerable. The length of time to healing is an important factor in determining a person's recovery after a fracture. Ultrasound may have a therapeutic role in reducing the time to union after fracture. This is an update of a review previously published in February 2012. OBJECTIVES To assess the effects of low-intensity ultrasound (LIPUS), high-intensity focused ultrasound (HIFUS) and extracorporeal shockwave therapies (ECSW) as part of the treatment of acute fractures in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (2 June 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 5), MEDLINE (1946 to May Week 3 2014), EMBASE (1980 to 2014 Week 22), trial registers and reference lists of articles. SELECTION CRITERIA Randomised and quasi-randomised controlled trials evaluating ultrasound treatment in the management of acute fractures in adults. Studies had to include participants over 18 years of age with acute fractures, reporting outcomes such as function; time to union; non-union; secondary procedures such as for fixation or delayed union or non-union; adverse effects; pain; costs; and patient adherence. DATA COLLECTION AND ANALYSIS Two authors independently extracted data from the included studies. Treatment effects were assessed using mean differences, standardised mean differences or risk ratios using a fixed-effect model, except where there was substantial heterogeneity, when data were pooled using a random-effects model. Results from 'worst case' analyses, which gave more conservative estimates of treatment effects for time to fracture union, are reported in preference to those from 'as reported' analyses. MAIN RESULTS We included 12 studies, involving 622 participants with 648 fractures. Eight studies were randomised placebo-controlled trials, two were randomised controlled trials without placebo controls, one was a quasi-randomised placebo-controlled trial and one was a quasi-randomised controlled trial without placebo control. Eleven trials tested LIPUS and one trial tested ECSW. Four trials included participants with conservatively treated upper limb complete fractures and six trials included participants with lower limb complete fractures; these were surgically fixed in four trials. The remaining two trials reported results for conservatively treated tibial stress fractures.'Risk of bias' assessment of the included studies was hampered by the poor reporting of methods, frequently resulting in the risk of bias of individual domains being judged as 'unclear'. Both quasi-randomised studies were at high risk of bias, including selection and attrition bias. Three studies were at low risk of selection bias relating to allocation concealment the majority of studies were at low risk of performance bias as they employed a form of intervention blinding.Only limited data were available from three of only four studies reporting on functional outcome. One study of complete fractures found little evidence of a difference between the two groups in the time to return to work (mean difference (MD) 1.95 days favouring control, 95% confidence interval (CI) -2.18 to 6.08; 101 participants). Pooled data from two studies found LIPUS did not significantly affect the time to return to training or duty in soldiers or midshipmen with stress fractures (MD -8.55 days, 95% CI -22.71 to 5.61; 93 participants).We adopted a conservative strategy for data analysis that was more likely to underestimate than to overestimate a benefit of the intervention. After pooling results from eight studies (446 fractures), the data showed no statistically significant reduction in time to union of complete fractures treated with LIPUS (standardised mean difference (SMD) -0.47, 95% CI -1.14 to 0.20). This result could include a clinically important benefit or harm, and should be seen in the context of the highly significant statistical heterogeneity (I² = 90%). This heterogeneity was not explained by the a priori subgroup analyses (upper limb versus lower limb fracture, smoking status). An additional subgroup analysis comparing conservatively and operatively treated fractures raised the possibility that LIPUS may be effective in reducing healing time in conservatively managed fractures, but the test for subgroup differences did not confirm a significant difference between the subgroups.Pooled results from five of the eight trials (333 fractures) reporting proportion of delayed union or non-union showed no significant difference between LIPUS and control (10/168 versus 13/165; RR 0.75; 95% CI 0.24 to 2.28). Adverse effects directly associated with LIPUS and associated devices were found to be few and minor, and compliance with treatment was generally good. One study reporting on pain scores found no difference between groups at eight weeks (101 participants).One quasi-randomised study found no significant difference in non-union at 12 months between internal fixation supplemented with ECSW and internal fixation alone (3/27 versus 6/30; RR 0.56, 95% CI 0.15 to 2.01). There was a clinically small but statistically significant difference in the visual analogue scores for pain in favour of ECSW at three month follow-up (MD -0.80, 95% CI -1.23 to -0.37). The only reported complication was infection, with no significant difference between the two groups. AUTHORS' CONCLUSIONS While a potential benefit of ultrasound for the treatment of acute fractures in adults cannot be ruled out, the currently available evidence from a set of clinically heterogeneous trials is insufficient to support the routine use of this intervention in clinical practice. Future trials should record functional outcomes and follow-up all trial participants.

Fractures to the proximal fifth metatarsal bone are among the most frequent injuries to the foot. Various classifications intend to distinguish different fracture entities in regard to prognosis and treatment. The most commonly used classification by Lawrence and Botte delineates three fracture zones and gives treatment recommendations based on retrospective case series. Aim of our study was to critically review the literature and reevaluate the classification and treatment recommendations based on the highest level of evidence available. We performed a systematic literature search in Medline, Embase and Cochrane library and identified six prospective trials either comparing the same treatment for different fracture entities or different treatment strategies for the same fracture entity. The studies reveal that all "tuberosity avulsion fractures" (Zone 1, according to Lawrence and Botte) heal well using functional treatment. Even multifragmentary, displaced and intraarticular fractures in Zone 1 give comparable good results. Treatment with a short leg cast leads to a significant delay in return to preinjury level when compared to functional treatment. "Jones' fractures" (Zone 2) also demonstrate good to excellent results and complete bone healing when treated functionally. In contrast, "diaphyseal stress fractures" (Zone 3) at the distal limit of the fourth-fifth intermetatarsal articulation and just distally feature a significantly higher rate of treatment failure when treated non-operatively in a non-weight bearing short leg cast. Early intramedullary screw fixation leads to a significantly shorter time to bone healing and return to sport. In conclusion, acute fractures to the proximal fifth metatarsal bone should be classified into two entities only: First, metaphyseal fractures not extending beyond the distal end of the fourth-fifth intermetatarsal articulation, as these fractures, regardless the number of fragments, displacement and intraarticular involvement, should be treated functionally. Second, meta-diaphyseal fractures located at the distal end of the fourth-fifth intermetatarsal articulation or just distally, as these fractures require early intramedullary screw fixation.

Abstract
BACKGROUND The morbidity and socioeconomic costs of fractures are considerable. The length of time to healing is an important factor in determining a patient's recovery after a fracture. Ultrasound may have a therapeutic role in reducing the time to union after fracture. OBJECTIVES To assess the effects of low intensity ultrasound (LIPUS), high intensity focused ultrasound (HIFUS) and extracorporeal shockwave therapies (ECSW) as part of the treatment of acute fractures in adults. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (December 2011), the Cochrane Central Register of Controlled Trials (in The Cochrane Library 2011, Issue 4), MEDLINE (1950 to November Week 3 2011), EMBASE (1980 to 2011 Week 49), trial registers and reference lists of articles. SELECTION CRITERIA Randomised controlled trials evaluating ultrasound treatment in the management of acute fractures in adults. Studies including participants over 18 years of age with acute fractures, reporting functional outcomes, time to union, non-union, secondary procedures such as for fixation or delayed or non-union, adverse effects, pain, costs or patient adherence were included. DATA COLLECTION AND ANALYSIS Two authors independently extracted data from the included studies. Treatment effects were assessed using mean differences or risk ratios and, where there was substantial heterogeneity, pooled using a random-effects model. Results from 'worst case' analyses, which gave more conservative estimates of treatment effects for time to fracture union, are reported in preference to those from 'as reported' analyses. MAIN RESULTS Twelve studies, involving 622 participants with 648 fractures, were included. Eight studies were randomised placebo-controlled trials, two studies were randomised controlled trials without placebo controls, one study was a quasi-randomised placebo controlled trial and the remaining study was a quasi-randomised controlled trial without placebo control. Eleven trials tested LIPUS and one trial tested ECSW. Four trials included participants with conservatively treated upper limb complete fractures and six trials included participants with lower limb complete fractures; these were surgically fixed in four trials. The remaining two trials reported results for conservatively treated tibial stress fractures.Very limited data from two complete fracture studies showed no difference between ultrasound and placebo control in functional outcome. Pooled estimates from two studies found LIPUS did not significantly affect the time to return to training or duty in soldiers or midshipmen with stress fractures (mean difference -8.55 days, 95% CI -22.71 to 5.61).Based on a 'worst case' analysis, which adjusted for incomplete data, pooled results from eight heterogeneous studies showed no statistically significant reduction in time to union of complete fractures treated with LIPUS (standardised mean difference -0.47, 95% CI -1.14 to 0.20). This result could include a clinically important benefit or harm, and should be seen in the context of the highly significant statistical heterogeneity (I² = 90%). This heterogeneity was not explained by the a priori subgroup analyses (upper limb versus lower limb fracture, smoking status). An additional subgroup analysis comparing conservatively and operatively treated fractures raised the possibility that LIPUS may be effective in reducing healing time in conservatively managed fractures, but the test for subgroup differences did not confirm a significant difference between the subgroups.Pooled results from eight trials reporting proportion of delayed union or non-union showed no significant difference between LIPUS and control. Adverse effects directly associated with LIPUS and associated devices were found to be few and minor, and compliance with treatment was generally good. One study reporting on pain scores found no difference between groups at eight weeks.One quasi-randomised study (59 fractures) found no significant difference between ECSW and no-placebo control groups in non-union at 12 months (risk ratio 0.56, 95% CI 0.15 to 2.01). There was a clinically small but statistically significant difference in the visual analogue scores for pain in favour of ECSW at three month follow-up. The only reported complication was infection, with no significant difference between the two groups. AUTHORS' CONCLUSIONS While a potential benefit of ultrasound for the treatment of acute fractures in adults cannot be ruled out, the currently available evidence from a set of clinically heterogeneous trials is insufficient to support the routine use of this intervention in clinical practice. Future trials should record functional outcomes and follow-up all trial participants.

Displaced midshaft fractures of the clavicle: non-operative treatment versus plate fixation (Sleutel-TRIAL). A multicentre randomised controlled trial. BMC Musculoskelet Disord 2011; 12:196. [PMID: 21864352 PMCID: PMC3175212 DOI: 10.1186/1471-2474-12-196] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2011] [Accepted: 08/24/2011] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND The traditional view that the vast majority of midshaft clavicular fractures heal with good functional outcomes following non-operative treatment may be no longer valid for all midshaft clavicular fractures. Recent studies have presented a relatively high incidence of non-union and identified speciic limitations of the shoulder function in subgroups of patients with these injuries. AIM A prospective, multicentre randomised controlled trial (RCT) will be conducted in 21 hospitals in the Netherlands, comparing fracture consolidation and shoulder function after either non-operative treatment with a sling or a plate fixation. METHODS/DESIGN A total of 350 patients will be included, between 18 and 60 years of age, with a dislocated midshaft clavicular fracture. The primary outcome is the incidence of non-union, which will be determined with standardised X-rays (Antero-Posterior and 30 degrees caudocephalad view). Secondary outcome will be the functional outcome, measured using the Constant Score. Strength of the shoulder muscles will be measured with a handheld dynamometer (MicroFET2). Furthermore, the health-related Quality of Life score (ShortForm-36) and the Disabilities of Arm, Shoulder and Hand (DASH) Outcome Measure will be monitored as subjective parameters. Data on complications, bone union, cosmetic aspects and use of painkillers will be collected with follow-up questionnaires. The follow-up time will be two years. All patients will be monitored at regular intervals over the subsequent twelve months (two and six weeks, three months and one year). After two years an interview by telephone and a written survey will be performed to evaluate the two-year functional and mechanical outcomes. All data will be analysed on an intention-to-treat basis, using univariate and multivariate analyses. DISCUSSION This trial will provide level-1 evidence for the comparison of consolidation and functional outcome between two standardised treatment options for dislocated midshaft clavicular fractures. The gathered data may support the development of a clinical guideline for treatment of clavicular fractures. TRIAL REGISTRATION Netherlands National Trial Register NTR2399.

Abstract
Traditionally, midshaft clavicular fractures have been treated conservatively. However a review of the literature reveals that certain fractures can benefit from operative repair. Conservative treatment, preferably in the form of a sling, of an undisplaced midshaft clavicular fracture leads to excellent results . Dislocated fractures have an increased risk of non-union or malunion. Intramedullary fixation can give good results in simple dislocated fractures, but does not provide optimal preservation of length and rotation in comminuted fractures. Plate osteosynthesis can be used for all clavicular fractures and causes a reduction of the relative risk of non-union of 86%. Due to the increased risk of non-union or malunion and of a worse functional result, osteosynthesis should be considered for patients with dislocated or comminuted midshaft clavicular fractures, with due consideration for the patient's expectations and lifestyle.

Abstract
Twenty-four proximal humeral fractures were treated by surgical internal fixation with a locked antegrade intramedullary nail. The purpose of this paper was to assess the clinical outcomes of proximal epiphyseal and diaphyseal humeral fractures treated with an antegrade humeral nail implanted after an interval rotator split. We treated six proximal epiphyseal fractures and seven bifocal fractures of the epiphysis and shaft and eleven diaphyseal fractures. The mean follow-up was 23 months (range 12 to 34 months). Twenty patients were available for follow-up. All but two fractures progressed to healing. The Mean Constant score was 80%, Relative Constant score was 95.5%. We divided the clinical outcomes by fracture pattern to define the best surgical indication. There were good clinical outcomes in all three groups, but the clinical score was highest in the shaft fracture group. An intramedullary antegrade nail inserted through the interval rotator without penetrating the rotator cuff had a good clinical outcome and with certain fracture types can be an effective and satisfactory device.

Abstract
OBJECTIVE To present the clinical and radiological results of treatment of periprosthetic fractures of the femur after hip and knee replacements. SUBJECTS AND METHODS Thirty-four patients (8 males and 26 females) with 34 fractures of the femur complicating hip and knee replacements are the subjects of this report. In 21 cases, the fracture affected the femur after hip replacement, and in 13 cases after knee replacement. Fractures around the hip replacement were classified according to Vancouver classification, and those around the knee replacement were classified according to Rorabeck. Location of fracture was defined as metaphyseal or diaphyseal. Arbitrary classification of fracture union was used. Fractures were considered to be either united or to have delayed union, after radiology. Conservative treatment and different methods of fixation were used. Clinical correlations between location of fracture and outcome were analyzed. RESULTS All 21 metaphyseal fractures after hip and knee replacements united. Eight diaphyseal fractures (6 after hip replacement and 2 after knee replacement) united. Five diaphyseal fractures after hip replacement had delayed union, and 4 fractures united after bone graft. In 1 case, fracture did not unite, the treatment was discontinued and the patient was lost to follow-up. CONCLUSION Our data show that metaphyseal fractures, regardless of type of implant, had better healing potential and did not require additional surgery. Diaphyseal fractures of the femoral shaft around the stem of femoral component of the hip or knee prosthesis required a bone graft and had less favorable outcomes. Women were more frequently affected by periprosthetic femoral fractures.

Abstract
The authors present their experience related to extreme complications in treatment of diaphyseal fractures of the long bones with application of the Fixion expansion intramedullary nail in a total of 48 surgeries. We have encountered six (12.5%) extreme complications in the management of fractures of 3 humeral, 2 tibial, and 1 femoral bones during its application procedure and postoperative follow-up. Of six cases, two with humeral and tibial fractures developed nonunion and rotational instability because of failure of inflation of the Fixion nail. One of the Fixion nail in humerus was broken spontaneously, and one of the Fixion nail deflated at the follow-up and pseudoarthrosis developed in this patient. In a patient with osteogenesis imperfecta, during the inflation of the nail for the treatment of femur fracture, a new longitudinal fracture occurred and conventional non-locking intramedullary nail was inserted. In a patient with a tibia fracture that was treated with the Fixion nail, new fracture occurred due to its bending after weight bearing in the postoperative period. The Fixion nail application is a new technique for the intramedullar fixation of long bones. It is considered as an effective method for the selective fracture types of long bones. Application may need special training. Since the Fixion has not got rotational stability and rigidity as conventional nailing systems, bending and breaking of the nail may occur during postoperative period in patients with over obesity and hyperactivity. In patients with osteogenesis imperfecta, it may not be the first choice as a nailing system.

Abstract
External fixation (EF) of tibia fractures has been associated with nonunions and malunions at our large pediatric trauma center. This study was designed to determine the successes and shortcomings of EF, especially with respect to maintenance of alignment and time to union. We believe that this will contribute to the limited amount of literature examining the complications associated with this treatment modality in the pediatric population. Thirty-one consecutive high-energy tibia fractures treated with EF over 4.5 years were analyzed. There were 22 boys and 9 girls (4-17 years old; mean, 11.9 years). Mean length of follow-up was 15 months. Of the 31 fractures analyzed, 19 were open fractures (12 closed, 3 grade I, 9 grade II, and 7 grade III). Of 30 fractures, 3 required skin graft, whereas 7 required fasciotomy. Mean duration of EF was 3.2 months. Mean time to union was 4.8 months. For complication rates, 4 of 30 had delayed union, 2 of 30 had nonunion, 8 of 30 had minor malunion, 3 of 30 had major malunion, 3 of 30 had leg length discrepancy, 8 of 30 had pin track infection, 3 of 30 had wound infection, 2 of 30 had osteomyelitis, and 4 of 30 required surgery for nonunion. Time to union differed between those aged 11 years or younger and those aged 12 years or older (means of 3.2 and 6.0 months, respectively; P = 0.001). Union time also differed between those with closed or grade I open fractures and those with grade II or III open fractures (3.9 and 5.7 months, respectively; P = 0.035). Leg length discrepancy rate differed between children aged 11 years or younger and those aged 12 years or older (3/13 and 0/18, respectively; P = 0.05). Although EF has been touted as the standard treatment of high-energy pediatric tibia fractures, our close analysis revealed a high rate of problems such as long union times (especially ages >or=12), malunion, leg length discrepancy (especially ages <or=11), and pin track infection.

Abstract
BACKGROUND Recent studies have shown a high prevalence of symptomatic malunion and nonunion after nonoperative treatment of displaced midshaft clavicular fractures. We sought to compare patient-oriented outcome and complication rates following nonoperative treatment and those after plate fixation of displaced midshaft clavicular fractures. METHODS In a multicenter, prospective clinical trial, 132 patients with a displaced midshaft fracture of the clavicle were randomized (by sealed envelope) to either operative treatment with plate fixation (sixty-seven patients) or nonoperative treatment with a sling (sixty-five patients). Outcome analysis included standard clinical follow-up and the Constant shoulder score, the Disability of the Arm, Shoulder and Hand (DASH) score, and plain radiographs. One hundred and eleven patients (sixty-two managed operatively and forty-nine managed nonoperatively) completed one year of follow-up. There were no differences between the two groups with respect to patient demographics, mechanism of injury, associated injuries, Injury Severity Score, or fracture pattern. RESULTS Constant shoulder scores and DASH scores were significantly improved in the operative fixation group at all time-points (p = 0.001 and p < 0.01, respectively). The mean time to radiographic union was 28.4 weeks in the non-operative group compared with 16.4 weeks in the operative group (p = 0.001). There were two nonunions in the operative group compared with seven in the nonoperative group (p = 0.042). Symptomatic malunion developed in nine patients in the nonoperative group and in none in the operative group (p = 0.001). Most complications in the operative group were hardware-related (five patients had local irritation and/or prominence of the hardware, three had a wound infection, and one had mechanical failure). At one year after the injury, the patients in the operative group were more likely to be satisfied with the appearance of the shoulder (p = 0.001) and with the shoulder in general (p = 0.002) than were those in the nonoperative group. CONCLUSIONS Operative fixation of a displaced fracture of the clavicular shaft results in improved functional outcome and a lower rate of malunion and nonunion compared with nonoperative treatment at one year of follow-up. Hardware removal remains the most common reason for repeat intervention in the operative group. This study supports primary plate fixation of completely displaced midshaft clavicular fractures in active adult patients.
