A morphological review of medial malleolar fractures - A large single centre series.

BACKGROUND: Many approaches to management of medial malleolar fractures are described in the literature however, their morphology is under investigated. The aim of this study was to analyse the morphology of medial malleolar fractures to identify any association with medial malleolar fracture non-union or malunion. METHODS: Patients who had undergone surgical fixation of their MMF were identified from 2012 to 2022, using electronic patient records. Retrospective analysis of their preoperative, intraoperative, and postoperative radiographs was performed to determine their morphology and prevalence of non-union and malunion. Lauge-Hansen classification was used to characterise ankle fracture morphology and Herscovici classification to characterise MMF morphology. RESULTS: A total of 650 patients were identified across a 10-year period which could be included in the study. The overall non-union rate for our cohort was 18.77% (122/650). The overall malunion rate was 6.92% (45/650). Herscovici type A fractures were significantly more frequently mal-reduced at time of surgery as compared to other fracture types (p = .003). Medial wall blowout combined with Hercovici type B fractures showed a significant increase in malunion rate. There is a higher rate of bone union in patients who had been anatomically reduced. CONCLUSION: The morphology of medial malleolar fractures does have an impact of the radiological outcome following surgical management. Medial wall blowout fractures were most prevalent in adduction-type injuries; however, it should not be ruled out in rotational injuries with medial wall blowouts combined with and Herscovici type B fractures showing a significant increase in malunions. Herscovici type A fractures had significantly higher malreductions. LEVEL OF EVIDENCE: Level 3 - Retrospective Cohort Study.

Malunions following lower extremity fractures in veterans with a spinal cord injury/disorder.

BACKGROUND: Nearly 50% of all persons with a spinal cord injury/disorder (SCI/D) will sustain an osteoporotic fracture sometime in their life, with lower extremity fractures being the most common. There are a number of complications that can occur post fracture, including fracture malunion. To date, there have been no dedicated investigations of malunions among persons with SCI/D. OBJECTIVES: The primary objective of this study was to identify risk factors associated with fracture malunion among fracture-related (type of fracture, fracture location, initial fracture treatment) and SCI/D-related factors. Secondary objectives were to describe treatment of fracture malunions and complications following these malunions. METHODS: Veterans with SCI/D with an incident lower extremity fracture and subsequent malunion from Fiscal Year (FY) 2005-2015 were selected from the Veteran Health Administration (VHA) databases using International Classification of Diseases, 9th edition (ICD-9) codes for lower extremity fractures and malunion. These fracture malunion cases underwent electronic health record (EHR) review to abstract information on potential risk factors, treatments and complications for malunion. Twenty-nine cases were identified with a fracture malunion with 28 of them successfully matched with Veterans with a lower extremity fracture during FY2005-FY2014 without a malunion (matched 1:4) based on having an outpatient utilization date of care within 30 days of the fracture case. There was trend towards more nonsurgical treatment in the malunion group (n = 27, 96.43%) compared to the control group (n = 101, 90.18%) (P = 0.05), though fracture treatment proved not to be not associated with developing a malunion in univariate logistic regression analyses (OR = 0.30; 95% CI: 0.08-1.09). In multivariate analyses, Veterans with tetraplegia were significantly less likely (approximately 3-fold) to have a fracture malunion (OR = 0.38; 95% CI: 0.14-0.93) compared to those with paraplegia. Fracture malunion was significantly less likely to occur for fractures of the ankle (OR = 0.02; 95% CI: 0-0.13) or the hip (OR = 0.15; 95% CI: 0.03-0.56) compared to femur fractures. Fracture malunions were rarely treated. The most common complications following malunions were pressure injuries (56.3%) followed by osteomyelitis (25.0%). CONCLUSIONS: Persons with tetraplegia as well as fractures of the ankle and hip (compared to the femur) were less likely to develop a fracture malunion. Attention to prevention of avoidable pressure injuries following a fracture malunion is important.

Distal radial fractures: a nationwide register study on corrective osteotomies after malunion.

The aim of the present study was to explore the incidence of corrective osteotomies after conservatively treated distal radial fracture and the risk for late correction depending on the patient's age. Based on data from the Finnish National Care Register of Health Care, Specialist Care, on all corrective osteotomies carried out in Finland during 2015-2019 in adults aged ≥20 years, we calculated the mean annual incidence rates per 100,000 person-years, standardized with the European Standard Population 2013. Using multivariable logistic regression, we calculated the risk of corrective osteotomies in various age groups. In total, 41,418 distal radial fractures were identified. Of those, 10,577 received surgical treatment in the acute phase. The incidence rate of primary operations for distal radial fractures was 47.9 per 100, 000 person-years. A total of 321 conservatively treated fractures needed corrective osteoteomy, with a surprisingly low mean annual incidence rate of 1.5 per 100,000 person-years. The risk for this was highest in patients in their fourth or fifth decade.Level of evidence: III.

The Impact of Treatment Delay on Malunion and Nonunion After Open Reduction of Mandible Fractures.

Importance: Time to surgical intervention is an oft-investigated potentially modifiable risk factor for complications after mandible fracture. Objective: To identify novel risk factors for malunion/nonunion after mandible fracture and determine the impact of treatment delay on malunion and nonunion after open reduction of mandible fractures. Design: Retrospective cohort. Setting and Participants: Encounter billing records from the New York State Inpatient Databases, State Emergency Department Databases, and State Ambulatory Surgery Databases. Patients aged 18 years and older with isolated mandible fracture in the emergency department or inpatient setting from January 1, 2006 to September 30, 2015. Main Outcomes and Measures: Mandibular Malunion/Nonunion. Results: A total of 19,152 adults were diagnosed with isolated mandible fracture. After fracture, 247 patients (1.3%) developed mandibular malunion or nonunion. In multivariable analysis, patients with open fractures (odds ratio [OR] 1.93, confidence interval [95% CI] 1.40-2.65), body fractures (OR 2.00, 1.50-2.65), alcohol abuse (OR 1.61, 1.22-2.11), diabetes mellitus (OR 1.57, 1.02-2.42), and Medicaid insurance (OR 1.46, 1.03-2.07) had increased risk, whereas patients with subcondylar fractures had reduced risk (OR 0.45, 0.28-0.72) of mandibular malunion/nonunion. The risk of mandibular malunion/nonunion after open reduction increased with treatment delay until 6-7 days after presentation (OR 1.84, 1.11-3.06). Conclusion and Relevance: Although treatment delay is often unavoidable, these findings suggest that physicians should consider early intervention in patients requiring open reduction of mandible fractures when able.

The Rates of Nonunion and Malunion in Lower Extremity Fractures: Experience in South Carolina over 17 years.

Our purpose was to determine the rates of lower extremity nonunion and malunion over 17 years in South Carolina. Our hypothesis was that malunions and nonunions decreased over time due to improved access to trauma centers and improved orthopaedic surgical training. The South Carolina Department of Budget and Control Hospital Discharge Database was queried between 1998-2014 and yielded a total of 4,994 malunions and 16,454 nonunions. Malunions increased from 1.2% (1998) to 1.8% (2010); nonunions increased from 4.0% (1999) to 5.8% (2011). Older age and gender were predictive of malunion and nonunion. This study identified females as having a higher odds ratio for malunion or nonunion; higher nonunion rates in worker's compensation or government payer status; and older age as incurring greater risks for sustaining fractures or developing a malunion or nonunion. There was increased prevalence of nonunion and malunion despite improved access to trauma centers and trained orthopaedic trauma surgeons.

Comparison between open reduction with internal fixation to circular external fixation for tibial plateau fractures: A systematic review and meta-analysis.

Peer-reviewed published studies on tibial plateau fractures treated with either open reduction with internal fixation (ORIF) or circular external fixation were reviewed to compare functional, radiological outcomes, postoperative complications, and reoperation rates between the two methods. A systematic search of various databases including Medline, Cochrane Controlled Register of Trials (CENTRAL), ScienceDirect, and Google Scholar from inception until June 2019 was performed. 17 studies with 1168 participants were included in the review. Most of the studies (76%) were retrospective in nature and had low or unclear bias risks. Incidence of total infection (Odds ratio [OR], 2.58; 95% CI, 1.33-5.02) and malunions (OR, 2.56; 95% CI, 1.12-5.84) were higher and length of hospital stay was shorter in patients treated with circular external fixator (Mean difference [MD], -6.1; 95% CI, -11.1--1.19). There were no differences in the incidence of secondary osteoarthritis (OR, 1.49; 95% CI, 0.92-2.42), range of motion (MD, 2.28; 95% CI, -11.27-15.82) non-union (OR, 1.44; 95% CI, 0.14-14.27) and reoperation rates (OR, 1.84; 95% CI, 0.90-3.78) between the two groups. Results from this investigation suggest that circular fixation may offer some advantages over ORIF such as a shortened length of hospital stay and early return to preinjury activities. Definitive clinical recommendations cannot be made as it also presents higher rates of postoperative complications than ORIF.

Complications associated with hexapod circular fixation for acute fractures of the tibia diaphysis: A retrospective descriptive study at a high volume trauma centre.

The use of hexapod circular external fixation in acute tibia fracture care is increasing as more general orthopaedic surgeons are gaining expertise with the use of this treatment modality. Limited data is currently available on the complications that may be encountered with this treatment strategy. AIM: To review the complications and outcomes of acute diaphyseal tibia fractures definitively treated with hexapod circular external fixation at a high volume orthopaedic trauma centre. METHODS: Retrospective review of clinical and radiological data of adult patients with acute diaphyseal tibia fractures treated with hexapod external fixation between 2012 and 2015 at a single centre. RESULTS: A total of 102 diaphyseal fractures were definitively treated with hexapod circular external fixation. Union was achieved in 101 cases with an average time to union of 25.6 weeks. Complications included pin site infection (56%); wound complications (19.67%); osteitis (11.76%); malunion (15.69%) and knee and ankle joint contractures (31.32%). CONCLUSION: Hexapod circular external fixation as definitive treatment of for diaphyseal tibia fractures demonstrates an excellent union rate with acceptable time to union. Complications rates are comparable to that of all fine wire circular fixators. Malalignment in is however a concern, considering that this device enables the surgeon to achieve accurate alignment through gradual deformity correction aided by computer software.

Replacement or repair of terrible triad of the elbow: A systematic review and meta-analysis.

BACKGROUND: Surgical treatment for terrible triad injuries remains a challenging clinical problem, and controversy exists of whether it is better to repair or replace the radial head. The objective of this systematic review was to evaluate the clinical outcomes of repair and arthroplasty replacement of the radial head in patients with terrible triad injury. METHODS: Medline, Cochrane Library, EMBASE, and Google Scholar were searched up to July 30, 2018 to identify the relevant studies, which included patients who had received treatments of the terrible triad of the elbow and also had reported with the quantitative outcomes. Outcomes of interest were functional outcomes. RESULTS: Four studies with a total of 115 patients were included in the systematic review. Most patients were type II or III radial head fractures based on the Mason classification systems. Fifty-one patients received radial head repair surgery and 64 underwent replacement. Two studies had indicated that patients in the replacement group were significantly associated with better treatment outcome assessed by DASH (Disabilities of the Arm, Shoulder and Hand) and MEPS (Mayo Elbow Performance Score) scores. The meta-analysis indicated that patients with the arthroplasty replacement were associated with significantly better ROM outcomes in flexion, extension, pronation than those with radial head repaired. In addition, patients in the replacement group showed fewer post-surgery complications than those in the repair group. CONCLUSIONS: Our review had indicated that patients with terrible triad injuries undergo arthroplasty replacement have better clinical outcomes and fewer post-surgery complications than those received the repair surgery. Radial head replacement might be a more effective treatment approach with good clinical outcomes for patients with a terrible triad of the elbow.

Lower Complication Rate Following Ankle Fracture Fixation by Orthopaedic Surgeons Versus Podiatrists.

INTRODUCTION: Increased overlap in the scope of practice between orthopaedic surgeons and podiatrists has led to increased podiatric treatment of foot and ankle injuries. However, a paucity of studies exists in the literature comparing orthopaedic and podiatric outcomes following ankle fracture fixation. METHODS: Using an insurance claims database, 11,745 patients who underwent ankle fracture fixation between 2007 and 2015 were retrospectively evaluated. Patient data were analyzed based on the provider type. Complications were identified by the International Classification of Diseases, Ninth Revision, codes, and revision surgeries were identified by the Current Procedural Terminology codes. Complications analyzed included malunion/nonunion, infection, deep vein thrombosis, and rates of irrigation and débridement. Risk factors for complications were compared using the Charlson Comorbidity Index. RESULTS: Overall, 11,115 patients were treated by orthopaedic surgeons and 630 patients were treated by podiatrists. From 2007 to 2015, the percentage of ankle fractures surgically treated by podiatrists had increased, whereas that treated by orthopaedic surgeons had decreased. Surgical treatment by podiatrists was associated with higher malunion/nonunion rates among all types of ankle fractures. No differences in complications were observed in patients with unimalleolar fractures. In patients with bimalleolar or trimalleolar fractures, treatment by a podiatrist was associated with higher malunion/nonunion rates. Patients treated by orthopaedic surgeons versus podiatrists had similar comorbidity profiles. DISCUSSION: Surgical treatment of ankle fractures by orthopaedic surgeons was associated with lower rates of malunion/nonunion when compared with that by podiatrists. The reasons for these differences are likely multifactorial but warrants further investigation. Our findings have important implications in patients who must choose a surgeon to surgically manage their ankle fracture, as well as policymakers who determine the scope of practice. LEVEL OF EVIDENCE: Level III-retrospective cohort study.

Incidence of deep infection, union and malunion for open diaphyseal femoral shaft fractures treated with IM nailing: A systematic review.

BACKGROUND: and purpose: We have undertaken a systematic review to evaluate the clinical results of intramedullary nailing (IMN) for open diaphyseal femoral fractures on the rates of union, delayed union, malunion, superficial and deep infection and bone grafting. METHODS: We searched the electronic databases of EMBASE, MEDLINE, from their inception until December 1st, 2017 with no language restrictions. The reference lists of all included articles and relevant reviews were also examined for potentially eligible studies. Hand search using electronic database of recent major orthopaedic journals was also carried. Two reviewers working independently extracted study characteristics and data to estimate the diagnostic odds ratio and 95% confidence interval for each result. RESULTS: Seventeen studies were eligible. Pooled estimate of effect size for union rate was 97% (95% CI: 94-99%). Deep infection rate was 6% (95% CI: 3-9.3%) and more prominent in Gustilo type III injuries; superficial infection was 5.6% (95% CI: 3-9.3%). Delayed union rate 3% (95% CI: 1-5.6%) while, malunion rate was 8.4% (95% CI: 5.7-11.6%). The need for bone grafting ranged from 0 to 9%. CONCLUSIONS: IMN remains the treatment of choice for open femoral diaphyseal fractures with very good union rates. Gustilo grade III injuries demonstrate a distinct higher deep infection rate and strict adherence to established surgical debridement and fixation protocols is advocated. The need for bone grafting can be as high as 9% and patients should be made aware of the possibility of requiring this additional procedure.

Risk factors associated with non-union after triple pelvic osteotomy (Toennis and Kalchschmidt technique): a case-control study and review of the literature.

INTRODUCTION: Dysplasia of the hip is a well known cause of secondary osteoarthritis of the hip. The triple pelvic osteotomy (TPO), according to the technique described by Toennis and Kalchschmidt, is a well established procedure to address dysplasia of the hip joint. Non-unions after triple pelvic osteotomies are rare and can occur at each of these osteotomies. The literature is lacking in studies investigating larger group of patients with non-unions after triple pelvic osteotomy. The aim of this study is to evaluate risk factors leading to a non-union after triple pelvic osteotomy. METHODS: A total of 53 patients with a non-union after triple pelvic osteotomy were included in this retrospective case-control. In addition, we identified a cohort of randomly selected patients undergoing hardware removal after triple pelvic osteotomy ("union" group) but had not developed non-union as the control group. This control group underwent the same procedure by the same group of surgeons in the same time period. The variables obtained from the review of the two groups were analyzed using appropriate statistical methods including Bivariable Analysis (p < 0.005) and Multivariable logistic regression analysis (p < 0.015). RESULTS: We identified a total of 53 patients out of the 3269 who had undergone TPO and had developed a non-union. The control group consisted of 117 patients who did not experience a non-union. Bivariable analysis of basic demographic characteristics demonstrated that gender, BMI, smoking, preoperative CE angle and degree of surgical correction did not differ significantly between the groups. There was a statistically significant (p < 0.05) difference between age (31.5 ± 9.4 vs. 27.5 ± 9.0 in the non-union and union groups, respectively; p = < 0.001) and postoperative CE angle (34.4 ± 5.0 vs. 32.8 ± 3.5 in the non-union and union groups, respectively; p = 0.02). Multivariable analysis demonstrated that an age over 30 was significantly associated with non-union (p = 0.01, OR 2.6, 95% CI 1.3-5.3). CONCLUSION: Non-unions after TPO are rare. A higher age and higher degree of surgical correction might be associated risk factors for developing a non-union. Furthermore, smoking, obesity and previous hip surgeries might also contribute to developing a non-union after triple pelvic osteotomy.

Complications of traditional bone setters (TBS) treatment of musculoskeletal injuries: experience in a private setting in Warri, South-South Nigeria.

INTRODUCTION: Complications arising from the practice of traditional bone setting is a major contributor to the challenges the orthodox orthopaedic practitioner in Nigeria faces. We share our experience at a multi-specialist private health facility in Warri, South-south, Nigeria. METHODS: Case notes of patients with musculoskeletal injuries who had prior treatment by traditional bone setters with resulting complications before presenting at our health facility for treatment were reviewed and relevant information extracted and entered in an already prepared proforma. Data were analysed using SPSS version 17 and results presented in form of means, percentages, ratios and tables. RESULTS: 43 cases were reviewed in a period of 8 years. There were 21 males and 22 females. The average age of patients was 44.8 ± 20.3 years. The most frequent age group affected was that of 40-49 years. 45.8% of the initial injuries were due to road traffic accidents while 39.5% resulted from falls. Femoral fractures and humeral fractures formed 20.4% and 14.8% of cases respectively. 40.8% of traditional bone setters complications observed were non-union of fractures of various bones followed by mal-union in 24.5% of cases. CONCLUSION: The observed complications of traditional bone setters practice in this study were similar to those previously reported in the literature. These complications constitute a significant challenge to the orthopaedic practitioner in Africa with associated negative socioeconomic impact on our society. Government and other relevant stakeholders need to unite and take decisive actions to mitigate this problem.

Surgical Complications Associated With Atypical Femur Fractures Attributed to Bisphosphonate Use.

Complications of atypical femur fractures (AFFs) are common. AFFs often receive the same treatment as other femoral fractures; however, there appears to be a higher rate of adverse outcomes. Nine patients sustained a total of 13 AFFs, had documented bisphosphonate use before fracture, and had surgery between 2006 and 2012. Complications included continued pain, surgical revision, nonunion, malunion, deformity, or heterotopic ossification. The overall complication rate was 33.3%, with four of the 12 surgeries performed at this institution resulting in one nonunion and three minor complications. None of the primary fixations required revision. There was a higher complication rate for AFFs when compared with non-bisphosphonate-related intramedullary nail femur fracture fixations. This cohort demonstrated a lower rate of major complications compared to the literature. Using a reamed, statically locked nail, halting bisphosphonate medication, and allowing early weight bearing is a safe and efficacious method to treat atypical femur fractures. (Journal of Surgical Orthopaedic Advances 27(1):14-20, 2018).

What Factors Influence Union and Refracture of Congenital Pseudarthrosis of the Tibia? A Multicenter Long-term Study.

OBJECTIVE: To identify factors influencing union of congenital pseudarthrosis of the tibia (CPT), refractures, and integrity of the tibia at maturity. METHODS: Data of 119 children operated for Crawford-type IV CPT and followed-up till skeletal maturity were analyzed. Logistic regression and recursive partitioning analyses were used to test associations between several variables and the outcome. RESULTS: Primary union occurred in 86% of children. At maturity, 69% remained soundly united. The odds ratio for failure of primary union was 3.89 (95% confidence interval, 1.05-14.40; P=0.042) when bone morphogenetic protein was used, and children who had a combination of the Ilizarov technique and intramedullary nailing were at risk for unsound union at maturity (odds ratio, 6.19; 95% confidence interval, 1.24-30.83; P=0.026). No other association reached statistical significance. On recursive partitioning, use of the Ilizarov technique, transfixing the ankle and subtalar joints, use of cortical graft and not operating on the fibula were associated with a better outcome; use of bone morphogenetic protein and combining intramedullary nailing with the Ilizarov technique were associated with poor results. CONCLUSIONS: A larger sample is needed to confirm which factors truly influence the outcome of CPT. This may be feasible if data are collected prospectively through a multicenter registry.

Lower extremity fractures in patients with spinal cord injury characteristics, outcome and risk factors for non-unions.

CONTEXT: Sublesional osteoporosis is an important sequel after spinal cord injury (SCI) resulting in a high incidence of fractures and impaired osseous healing due to altered bone metabolism. The following study aims to identify demographic characteristics and outcome of patients with SCI with lower extremity fractures. DESIGN: Retrospective observational study. SETTING: Level-I cross-regional trauma center. PARTICIPANTS: All patients with SCI suffering from osteoporotic/pathologic fractures during an 11-year-period (01/2003-12/2013) at the Center for Spinal Cord Injuries (Trauma Center Murnau) were analyzed via a chart review. OUTCOME MEASURES: Demographics, surgical and radiologic outcome as well as complication rate were assessed with a special emphasis on union rates and independent risk factors for non-unions. RESULTS: We identified 132 patients (105 males) who fulfilled the inclusion criteria. Most of them were paraplegic (n=101) and showed motor complete syndromes (n=119). Supracondylar femur fractures were the most prevalent in this study (n=47). We observed a non-union rate of 15.9% (n=21). The development of pseudarthrosis was associated with the time interval since the initial SCI (P < 0.010), delayed in-patient submission (P < 0.038), fracture classification (P < 0.002) and the localization of the fracture (P < 0.0001). The overall complication rate was 16.7%. All dislocated subtrochanteric femur fractures (Garden III and IV) (n=10) developed a non-union, regardless of their management (conservative or surgical). The following independent predictors for non-unions were identified: fracture localization (P < 0.0002), fracture classification (P < 0.056), and fracture management (P < 0.036). CONCLUSIONS: Even though modern techniques allow surgical interventions in bones with reduced mineral density, non-unions remain a common complication in patients with SCI. Risk factors for non-unions of lower extremity fractures are identified.

Nonunion and delayed union in lateral open wedge distal femoral osteotomies-a legitimate concern?

INTRODUCTION: Due to a supposed high rate of nonunions in lateral open wedge distal femur osteotomy (LOWDFO), the medial closing wedge technique has been favoured for a long time. The aim of this study was to report the occurrence of delayed- and nonunions following LOWDFO. We hypothesized that the occurrence of nonunions needing revision surgery is comparable to medial closing osteotomies. METHODS: Forty-one patients were treated with LOWDFO with a minimum follow-up of 12 months. Parameters such as age, gender, body mass index, valgus angle, the heights of the opening wedge, as well as the type of osteotomy (biplane vs single plane) were collected. Delayed union and nonunion were evaluated on radiographs along with clinical symptoms. RESULTS: The study group consisted of 21 females and 20 males, with a median age of 37 years at the time of surgery. Removal of hardware was performed in 63% after 1.3 years (0.6-2.1 years). The median preoperative valgus angle was 6.1° valgus (range 2-15.5°). The heights of the opening wedge ranged from 2 to 12 mm (mean 5.3 mm). Hinge fracture of the medial cortex was seen in 39%. Three patients had a delayed union, and one patient had a nonunion requiring revision surgery. CONCLUSION: LOWDFO is a safe alternative to MCWDFO. Although radiolucency of the osteotomy gap can be evident on radiographs even after 12 months, this does not reflect the clinical finding. The nonunion rate is proven to be low and comparable with the nonunion rates of MCWDFOs as well as open wedge HTOs.

Comparison of outcomes between partially healed and acute metaphyseally malaligned distal radial fracture treated by palmar locking plate fixation.

BACKGROUND: The purpose of this study was to determine whether a partially healed (surgical delay of 2-6 weeks) metaphyseally malaligned distal radius fracture (DRF) treated using the extended palmar approach with palmar locking plate fixation has poorer clinical or radiological outcomes than those of acute (surgical delay of ≤2 weeks) metaphyseally unstable DRF treated by palmar locking plate fixation. METHODS: We identified 24 patients (Group A) who were treated with palmar locking plate for a partially healed (surgical delay of 2-6 weeks) metaphyseally malaligned DRF. We selected 48 patients (Group B) who were treated with palmar locking plate among the acute (surgical delay of ≤2 weeks) metaphyseally unstable DRF to be individually matched in a 1:2 ratio for sex, age, and fracture type. The two study groups were compared with respect to clinical and radiological parameters. The clinical parameters examined were; wrist range of motion (flexion, extension, supination, and pronation), grip strength, and Disabilities of Arm, Shoulder and Hand (DASH) scores. Radiological measurements included radial inclination, palmar angulation, and ulnar variance. RESULTS: The wrist flexion and grip strength were significantly greater in group B than group A at 3 months postoperatively. However, wrist ranges of motion, grip strengths, and DASH scores were not significantly different at 1 year postoperatively. Radiographic evaluation demonstrated no intergroup difference in terms of radial inclination, palmar angulation, or ulnar variance at 1 year postoperatively. CONCLUSIONS: Partially healed metaphyseally malaligned healed DRFs had inferior clinical outcomes to acute metaphyseally unstable DRFs in an early postoperative period, however, achieved similar clinical outcomes at 1 year postoperatively when treated using palmar locking plate fixation.

How High Can You Go?: Retrograde Nailing of Proximal Femur Fractures.

There are no data-supported recommendations on how proximal is too proximal for retrograde nailing (RGN). At six level 1 trauma centers, patients with femur fractures within the proximal one-third of the femur treated with RGN were included. This article describes a proximal segment capture ratio (PSCR) and nail segment capture ratio to evaluate RGN of proximal fractures. The study included 107 patients. The average follow-up was 44 weeks. There were two nonunions and three malunions. There was no significant difference between PSCR of 0.3 or less and need for secondary procedures or time to full weight bearing (p>.05). In this study, a smaller (< 0.3) PSCR was not associated with an increased number of complications. A higher Orthopaedic Trauma Association classification was predictive of malunion and increased time to union. These data demonstrate that retrograde nailing is safe and effective for the treatment of supraisthmal femur fractures.

Low complication rate of elastic stable intramedullary nailing (ESIN) of pediatric forearm fractures: A retrospective study of 202 cases.

Elastic stable intramedullary nailing (ESIN) has been established as state of the art treatment for forearm fractures in children, if operative stabilization is required. Their use has been expanded to single bone shaft fractures, and also more complex injuries such as Monteggia fractures or Monteggia-like lesions. A wide range of complications has been reported in the literature, up to 70% in certain investigations. The purpose of this study was to assess the complication rate after ESIN treatment of forearm fractures in children and adolescents in a representative cohort of patients from a level 1 trauma center in Germany.Between 2000 and 2015, we retrospectively analyzed all patients, up to the age of 16 years, with forearm fractures, who were operatively treated using ESIN in our department of general and trauma surgery. The main outcome measurements were the rates of postoperative complications after ESIN such as re-fracture, malunion, nonunion, tendon lesion, wound infection, and limited range of motion.In all, 201 consecutive patients with 202 forearm fractures were included in this study. Age averaged 9.7 years (range 3-16 years). Fifteen (7.4%) fractures were open. Fractures were 82.2% diaphyseal both-bone forearm fractures. Follow-up averaged 10.2 months (range 0.7-176.3 months). Complications were 10 re-fractures, 2 malunions, 3 extensor pollicis longus tendon ruptures, 1 superficial wound infection, and 2 limited range of motions. Fourteen (6.9%) children required a secondary operative intervention for their complication. Time to implant removal averaged 3.8 months (range 0.4-16.3 months).Elastic stable intramedullary nailing is a minimally invasive and reliable technique with a low complication rate. Both-bone forearm fractures and single bone fractures, and also Monteggia and Monteggia-equivalent fractures can be successfully treated with this method. As a major complication, re-fractures are frequently seen, even with ESIN in situ.

Corrective osteotomy is an effective method of treating distal radius malunions with good long-term functional results.

INTRODUCTION: Malunion occurs in approximately 23% of non-operatively treated and 11% of operatively treated distal radius fractures. The decision whether to correct a malunion is primarily based on functional impairment and wrist pain. The purpose of this study was to assess the long-term functional outcomes of corrective osteotomies for symptomatic malunited distal radius fractures. METHODS: All consecutive corrective osteotomies of the distal radius performed in one centre between January 2009 and January 2016 were included. The primary outcome was the functional outcome assessed with the Disability of the Arm, Shoulder and Hand (DASH) and the Patient-Rated Wrist Evaluation (PRWE) score. Secondary outcomes were range of motion, grip strength, pain as indicated on the Visual Analogue Scale (VAS) before and after corrective osteotomy, radiological parameters, time to union and complications. Additionally, we aimed to determine if there were any difference in graft versus no graft usage. RESULTS: A total of 48 patients were included. The median age was 54.5 years (IQR 39-66) and 71% was female. The median time to follow-up was 27 months. The median DASH and PRWE score were respectively 10.0 (IQR 5.8-23.3) and 18.5. (6.5-37.0). Except for pronation and supination, range of motion and grip strength of the injured wrist were significantly less compared to the uninjured side. Palmar and dorsal flexion and radial and ulnar deviation of the injured wrist were significantly less compared with the uninjured side. VAS pain scores decreased significantly from 6.5 preoperative to 1.0 postoperative. The median time to union was 23 weeks (IQR 12-29.5). Eighteen patients (38%) had a complication for which additional treatment was required. Except for a significant difference in radial inclination and length after the corrective osteotomy in favour of graft usage, there were no significant differences between graft an no graft usage. CONCLUSIONS: Corrective osteotomy is an effective method of treating symptomatic distal radius malunions with good long-term functional results, measured with the DASH and PRWE score, and improvement in radiographic parameters and pain scores. Additionally, no differences in functional outcomes were found between graft and no graft usage.
