RESUMO
Background: The pins and rubber traction system (PRTS) has proven effective in managing intra-articular fractures of the proximal interphalangeal joint. However, there is scant evidence in the literature regarding its efficacy in treating distal interphalangeal joint (DIPJ). This study aims to investigate the outcomes of PRTS in the treatment of comminuted intra-articular fractures of the DIPJ. Methods: We conducted a retrospective review of patients with comminuted intra-articular fractures of the DIPJ treated with PRTS between 2017 and 2021. At the final follow-up, we measured and compared the active range of motion (ROM) in both affected and non-injured contralateral fingers. The subjective evaluation utilised the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire and the Visual Analogue Scale (VAS). Results: Ten patients with a mean follow-up of 13.2 months (range: 12-17) were included in the study. Fracture locations included the base of the distal phalanx in two patients, the condyle of the middle phalanx in seven and both in one patient. At the final follow-up, the average VAS score was 0.5 (range: 0-2). The average active motion of the DIPJ was 61° (range: 50°-70°) for the injured side and 76° (range: 75°-80°) for the opposite side. The mean range of DIPJ movement was 80% (range: 68%-87%) of the non-injured side. Extension deficits were observed in five patients, with a median deficit value of 10° (range: 5°-10°). The average Quick-DASH score was 2.9 (range: 0-11.3). Conclusions: The PRTS can be considered as an effective surgical technique in managing comminuted intra-articular fractures of the DIPJ. Level of Evidence: Level IV (Therapeutic).

An adult red-legged seriema (Cariama cristata) presented with a comminuted fracture of the tibiotarsus and fibula. Surgery was performed, and a type II external fixator, with 2 distal and 2 proximal pins, was used to stabilize the fracture. After a 10-day stabilization period, the bird developed a second fracture on the same bone, proximal to the first fracture site. Another surgery was performed on the seriema similar to the first one. However, in this second surgical procedure a single pin, instead of 2 perpendicular pins, was placed proximally to the fracture site. After the second surgical procedure, bone marrow stem cells (BMSCs) from the seriema's left ulna were collected. Twenty-seven days after the second surgery, the BMSCs were transplanted, into the fracture sites. Twenty-four days after the stem cells were injected into the fractures (51 days after the second surgical procedure), radiographic images revealed healing bone calluses at the fracture sites. The fracture healing was relatively long for this case (a total of 75 days). The addition of bone marrow stem cell therapy to the use of external fixation may have contributed to the healing observed radiographically 24 days after administration; therefore, bone marrow stem cell therapy, in addition to traditional surgical fracture reduction and stabilization, may be a promising therapeutic approach for avian cases with similar injuries and bone anatomy. However, as this is a single case, this therapeutic modality deserves further application and study. Moreover, we suggest modifications in the bone marrow stem cell collection and therapy, which may be useful for future studies and application involving birds.

OBJECTIVE: To report the successful treatment of septic nonunion in two dogs with large segmental defects secondary to long-bone fractures by using a novel human placenta-derived matrix (hPM) as adjunct to fixation. ANIMALS: One 3-kg 9-year-old neutered male Yorkshire terrier with a distal antebrachial fracture and one 6-kg 4-year-old spayed female miniature pinscher with a distal humeral fracture. STUDY DESIGN: Short case series. METHODS: Both dogs presented for septic nonunion after internal fixation of Gustilo type II open diaphyseal fractures from dog bite injuries. During revision, debridement of nonviable bone resulted in segmental defects of 32% and 20% of the bone length for the antebrachial and humeral fractures, respectively. The antebrachial fracture was stabilized with a circular external fixator, and the humeral fracture was stabilized with biaxial bone plating. The fracture sites were not collapsed, and full length was maintained with the fixation. Autogenous cancellous bone graft and canine demineralized bone allograft were packed into the defects, and hPM was injected into the graft sites after closure. RESULTS: Radiographic union was documented at 8 weeks and 6 weeks for the antebrachial and humeral fractures, respectively. Both dogs became fully weight bearing on the affected limbs and returned to full activity. CONCLUSION: Augmenting fixation with grafts and hPM led to a relatively rapid union in both dogs reported here.

Introduction: Comminuted distal radius fracture is one of the fractures that difficult to reduce. This study aimed to compare Patient-Rated Wrist Evaluation (PRWE) score between plating on second and third metacarpal groups. Methods: This study used a retrospective analytic research design with a sample of twenty seven cases of distal radius comminutive fractures that have been treated using dorsal distraction plating. Fifthteen cases with distal fixation in second metacarpal and twelve cases in third metacarpal. Data were then analyzed using the Mann-Whitney test. Results: The mean Pain scores in the second metacarpal and third metacarpal groups, respectively were 5.73 compared to 6.17. While the mean score of Function in the second metacarpal group and the third metacarpal group, respectively 12.67 compared to 13.83. The total PRWE score in the second metacarpal group was 18.40 compared to the third metacarpal group which was 20.0 (p>0.05). Conclusions: Patients with distal radius comminuted fracture treated using dorsal distraction plating with distal fixation in second metacarpal showed higher mean Pain, Function and total PRWE compared to third metacarpal, but there were no significant differences

The Essex-Lopresti injury is caused by a high energy mechanism and consists of a characteristic triad: a comminuted radial head fracture, disruption of the distal radioulnar joint, and tearing of the interosseous membrane. These injuries are often difficult to diagnosis on initial evaluation, and the majority are missed acutely. Chronic Essex-Lopresti injuries lead to radioulnar longitudinal instability, proximal radius migration, ulnocarpal impaction, and chronic elbow pain. These injuries present a challenging problem for the treating surgeon.

RATIONALE: The knee joint is an important weight-bearing joint, tibial plateau fractures affect knee function and stability. High-energy intra-articular fractures involving the tibial plateau can cause management-related problems such as wound dehiscence; severe comminution leading to malalignment; and delayed complications such as varus collapse, implant failure, and arthritis of the knee joint. The treatment of severe or complex tibial plateau fractures can be quite difficult. Traditional methods of open reduction and plating require extensive exposures, which may further compromise soft tissue and devascularize bone fragments, leading to infection. In this case, a novel device, double reverse traction combined with MIPPO technique, was used and provided the possibility of minimally invasive and personalized orthopedic surgery to treat severe comminuted Schatzker type VI tibial plateau fracture and tibial shaft fracture and got satisfactory results. PATIENT CONCERNS: A previously healthy 56-year-old man presented to the emergency room after a fall from a height, who lost the movement of the left knee with pain and swelling. DIAGNOSES: X-rays showed a tibial plateau comminuted fracture, Schatzker type VI, and tibial shaft fracture. INTERVENTIONS: Applying less extensile exposure and the indirect reduction technique of double reverse traction and closed reduction combined with minimally invasive percutaneous plate osteosynthesis (MIPPO) technique, we got satisfactory recovery of the severe comminuted Schatzker type VI tibial plateau fracture and tibial shaft fracture. OUTCOMES: This severe comminuted fracture and tibial shaft fracture were successfully reduced and got satisfactory recovery of knee joint function. LESSONS: Double reverse traction combined with MIPPO technique can reduce the risk of surgical complications, such as bleeding, oozing, and wound infection. It can be applied in patients with comorbidities such as cardiac disease, hypertension, and heart failure who may otherwise not be candidates for surgery. The cost burden is lower than that of the traditional traction table.

BACKGROUND: Humeral shaft fractures can be managed conservatively or operatively. Fracture characteristics were analyzed to identify patients who would benefit from early operative fixation. METHODS: We performed a retrospective cohort study of 126 consecutive humeral shaft fractures (2008-2015). Fractures were classified according to fracture type, location, separation, and comminution. RESULTS: Of 126 patients, 96 were managed conservatively. In 54%, union occurred before 26 weeks, and 13% had delayed union after 26 weeks, whereas 33% did not achieve union. Of 30 patients managed surgically, 63% had union before 26 weeks, 33% had delayed union, and 4% did not achieve union. A statistically significant difference favored operative management. This difference was maintained in specific fracture patterns (simple and spiral fractures) and locations (proximal- or distal-third humeral fractures). Early surgery had a significantly higher union rate than delayed surgery. No difference was present between plate and nail fixation regarding union or neurologic injury. Separation of fragments, open injury, and comminution were not associated with nonunion. A psychiatric history (including psychotic disorders, bipolar disorder, multiple involuntary psychiatric admissions, or dementia) was significantly associated with nonunion after conservative management (P = .016). Two patients with dementia died after their conservatively managed fractures progressed to open injuries. CONCLUSION: This study found high rates of delayed union and nonunion with conservative management. Patients with a significant psychiatric history may benefit from consideration of operative intervention.

BACKGROUND: It has been advocated that reduction of nasal bone fractures should be followed by internal packing and/or external splinting. Despite the ample literature concerning the advantages and limitations of various splint types, the necessity and effectiveness of external splinting has not been well documented. OBJECTIVE: To present the authors' experience and review the literature on treatment of nasal bone fractures, focusing on the indications and effectiveness of external splinting following closed reduction. STUDY DESIGN: Retrospective analysis and literature review. PATIENTS AND METHODS: Medical records of all patients, treated at the Department of Oral and Maxillofacial Surgery of the "KAT" General Hospital of Attica between January 2010 and December 2016 for facial trauma including nasal bone fractures, were retrospectively reviewed. Patient demographic data, fracture type, applied treatment, complications, and final outcome were registered. RESULTS: A total of 77 patients (58 males; 19 females) were included in the study. The age range was 18 to 65 years (mean, 37.8). Closed reduction without external splinting was performed in 63 patients and open reduction with internal fixation in 6; 8 severely comminuted fractures were treated with closed reduction and external splinting. The mean follow-up was 4.8 months. All severely comminuted fractures presented complications. CONCLUSIONS: External splinting following closed reduction of nasal bone fractures should not be used routinely but only in selected patients with severe comminution. Since the pertinent literature is inconclusive on the indications and effectiveness of external splinting, randomized controlled studies are warranted to fully elucidate the issue.

INTRODUCTION: Distal humerus intercondylar fractures are intra-articular comminuted fractures of the elbow that involve soft tissue injury. We evaluate different surgical approaches and elbow functional outcomes in the treatment of distal humerus fracture. MATERIALS AND METHODS: Medline, Cochrane, EMBASE, Google Scholar databases were searched up to 29 July 2016. All studies had to have evaluated the treatment of patients with intercondylar fractures of the distal humerus. The primary outcome was the incidence of functional grading of excellent/good. RESULTS: The methods used to evaluate elbow function were diverse across the studies and included non-surgical, fixation and plating approaches. The most common surgical technique used was olecranon osteotomy (n = 7) and triceps-sparing (n = 5). In general, most procedures were associated with >70% of patients having excellent/good joint function following surgery. The meta-analysis included four studies with 276 patients, and compared olecranon osteotomy with triceps-sparing. The pooled analysis indicated that patients treated using olecranon osteotomy had better functional outcome than patients treated with triceps-sparing (pooled OR = 2.38, 95%CI: 1.25-4.55, p = .009). CONCLUSIONS: This study found that a wide range of surgical procedures were effective in treating most patients with distal humerus intercondylar fractures, and that the approach of olecranon osteotomy may be more effective than that of triceps-sparing in restoring joint function. Key messages Most procedures in treating distal humerus intercondylar fractures were associated with >70% of patients having excellent/good joint function following surgery. The most common surgical technique used in treating distal humerus intercondylar fractures were olecranon osteotomy and triceps-sparing. The pooled analysis indicated that patients treated using olecranon osteotomy had better functional outcome than patients treated with triceps-sparing.

Successful results of osteoarticular allografts in reconstruction of periarticular bone defect after tumor resection encouraged its utilization in post-traumatic defects. Here we describe a case of post-traumatic skeletal defect in a 4 year-old girl treated with osteoarticular allograft reconstruction. Due to severity of the associated soft tissue injury and contamination at presentation staged treatment with antibiotic spacer followed by the reconstruction was carried out. At the end of one year the patient achieved 'Musculoskeletal tumor society' functional score of 27 points and radiographic score of 93%. Reconstruction immediately after healing of soft tissues prevented development of any varus or valgus deformity of the knee. Our case demonstrates utility of osteoarticular allograft in a pediatric post-traumatic skeletal defect.

PURPOSE: To compare the outcome following conservative or surgical treatment for displaced fracture of the medial process of the calcaneal tuberosity. METHODS: 14 men and 4 women aged 20 to 44 years chose to undergo conservative (9 feet) or surgical (10 feet) treatment by a single surgeon for closed displaced fracture of the medial process of the calcaneal tuberosity. The injury mechanism was a fall from a height of <1.5 m; the mean time from injury to treatment was 3 (range, 1-7) days. Conservative treatment comprised immobilisation in a plaster cast. Surgical treatment involved fixation with a halfthread cannulated screw for large fragments (in 6 feet) or a mini-plate for comminuted fragments (in 4 feet). At the final follow-up, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score was evaluated. RESULTS: The conservative and surgery groups were comparable in terms of age, gender, and fracture displacement. The mean follow-up duration was 20 (range, 14-24) months. All patients had bone union; none had implant loosening or breakage. One patient with surgical treatment developed skin numbness at the medial aspect of the heel that resolved following neurotrophic drug treatment for 3 months. The surgery group achieved earlier full weight-bearing (5.8 vs. 7.5 weeks, p<0.001) and return to work (5.9 vs. 8.2 weeks, p=0.048), but comparable AOFAS score (89.0 vs. 88.2, p=0.4). CONCLUSION: Surgery for displaced fracture of the medial process of the calcaneal tuberosity enabled earlier full weight-bearing and return to work but comparable AOFAS score.

Closed treatment for condylar fractures has long been widely accepted. With closed treatment, the deviated bone fragments heal in their new positions, and this may subsequently cause a range of functional impairments. The association between healing morphology and post-treatment functional impairment is unclear. In this study, computed tomography images of 26 patients (35 sides) who had undergone closed treatment for condylar fractures were used to perform a comparative investigation of three-dimensional (3D) bone morphology before and after treatment. As a result, the morphology of the condylar process after treatment was classified into four different patterns: unchanged, spherical, L-shaped, and detached. In terms of the association between fracture types and healing morphology, fractures of the condylar head healed in the spherical pattern, simple fractures of the condylar neck healed in the spherical or L-shaped pattern, and comminuted fractures of the condylar neck healed in the spherical, L-shaped, or detached pattern. The association between mandibular deviation and healing morphology was also investigated, and it was found that deviation was greater for the spherical and detached patterns than for the L-shaped pattern. The present findings indicate that 3D evaluation of the fractured condylar process is required to elucidate the association with functional impairment after healing.

PURPOSE: Mandibular fractures represent a substantial portion of facial fractures in the pediatric population. Pediatric mandibles differ from their adult counterparts in the presence of mixed dentition. Avoidance of injury to developing tooth follicles is critical. Simple mandibular fractures can be treated with intermaxillary fixation (IMF) using arch bars or bone screws. This report describes an alternative to these methods using silk sutures and an algorithm to assist in treating simple mandibular fractures in the pediatric population. PATIENTS AND METHODS: A retrospective chart review was performed and the records of 1 surgeon were examined. Pediatric patients who underwent treatment for a mandibular fracture in the operating room from 2011 to 2015 were identified using Common Procedural Terminology codes. Data collected included age, gender, type of fracture, type of treatment used, duration of fixation, and presence of complications. RESULTS: Five patients with a mean age of 6.8 years at presentation were identified. Fracture types were unilateral fractures of the condylar neck (n = 3), bilateral fractures of the condylar head (n = 1), and a unilateral fracture of the condylar head with an associated parasymphyseal fracture (n = 1). IMF was performed in 4 patients using silk sutures, and bone screw fixation was performed in the other patient. No post-treatment complications or malocclusion were reported. Average duration of IMF was 18.5 days. CONCLUSIONS: An algorithm is presented to assist in the treatment of pediatric mandibular fractures. Silk suture fixation is a viable and safe alternative to arch bars or bone screws for routine mandibular fractures.

BACKGROUND: To evaluate risk factors of redisplacement and remind surgeons of key factors regarding conservative treatment of distal radius fracture. METHODS: A total of 132 patients who received conservative treatment for distal radius fractures between March 2008 and February 2011 were included in this study. Radial inclination, radial length, volar tilting angle, ulnar variance, fragment translation, and presence of dorsal metaphyseal comminution were measured on the X-rays taken immediately after reduction, one week after injury during the first follow-up outpatient clinic visit, and after the gain of radiological union. Secondary displacement was defined as a loss of reduction during the follow-up period, and was divided into 'early' and 'late' categories. We analyzed the influence of initial displacement radiologic variables, dorsal cortex comminution, and patient age on the development of secondary displacement. RESULTS: Development of secondary displacement was significantly associated only with initial displacement radiologic variables (p < 0.001), development of the late secondary displacement was significantly associated with age (p = 0.005), and initial displacement radiologic variables were associated significantly with a serial increase in ulnar variance (p = 0.003). CONCLUSIONS: Greater displacement on the initial radiographs indicates a higher possibility of development for secondary displacement, and older patients had a higher probability of late secondary displacement development. Furthermore, dorsal comminutions did not affect secondary displacement directly.

Sternal nonunion is associated with high morbidity and treated using rigid plate and screw fixation. This is the first reported example of successful sternal reconstruction using adipose-derived stromal vascular fraction (SVF) stem cells in addition to traditional techniques. Mesenchymal stem cells, one component of the SVF, play an important role in bone healing and were therefore used to promote remedial processes in a patient with sternal nonunion. A 3D printed model of the patient's sternum was used for preoperative planning of the plating. Intraoperatively, SVF was isolated using ultrasonic cavitation and previously planned sternal plating was completed. A total of 300 million cells were delivered via both local injection and intravenously before chest closure. The patient's pain dramatically decreased, commensurate with healed areas of nonunion by 3 months and maintained at 6 months postoperatively, supported by three-dimensional computed tomography imaging. Utilizing autologous stem cells from the SVF in conjunction with existing plating techniques may provide an optimal platform to stabilize the sternum and promote bone healing, although additional study is recommended.

PURPOSE: To identify factors that affect functional outcome one year after distal radial fracture treatment. METHODS: 521 women and 121 men aged 16 to 92 (mean, 59) years with distal radial fractures underwent external fixation (n=123), open reduction and internal fixation (n=63), a combination of both (n=10), distal radial osteotomy for symptomatic malunion (n=90), or casting with (n=194) or without (n=162) prior closed manipulation under regional anaesthesia. The indication for surgery (rather than casting) was metaphyseal instability. Radiographic evaluation (dorsal angulation, radial shortening, carpal malalignment, and malunion) was made before and after treatment and after fracture healing. Functional evaluation (range of movement, grip strength, and activities of daily living) was made at a mean of 16 (range, 6-54) months after injury. RESULTS: After multiple regression analysis, poorer functional score was associated with increasing age (p<0.001), dorsal angulation after healing (p<0.016), presence of volar comminution (p=0.005), and pain (p<0.001). Poorer grip strength was associated with non-dominant side injury, increasing age, dorsal angulation after healing, positive ulnar variance, comminution, and pain (all p<0.001). Predicted malunion showed colinearity with age (r=0.657), dorsal comminution (r=0.694), and dorsal angulation (r=0.626). CONCLUSION: Understanding factors associated with outcome helps surgeons to make the treatment decision for distal radial fracture to achieve optimum outcome.

OBJECTIVES: To evaluate the treatment methods of mandibular symphyseal fracture combined with dislocated intracapsular condylar fractures (MSF&DICF) and to compare the effect of different treatment methods of condylar fractures. METHODS: Twenty-eight patients with MSF&DICF were included in this study. Twenty-two sites were treated by open reduction, and all the medial condylar fragments were fixed with titanium screws; whereas the other 22 sites underwent close treatment. The surgical effect between these 2 groups was compared based on clinical examination and radiographic examination results. RESULTS: Seventeen of 22 condyle fractures were repositioned in the surgery group, whereas 4 of 22 condyle fractures were repositioned in the close treatment group. Statistical difference was observed between these 2 groups (P < 0.01). Functional outcomes of the patients treated in the surgical treatment group also were better than those in the close treatment group. CONCLUSIONS: The dislocated intracapsular condyle fractures should be treated by surgical reduction with the maintenance of the attachment of lateral pterygoid muscle, which is beneficial to repositioning the dislocated condyle to its original physiological position, to closure of the mandibular lingual gap, to restore the mandibular width.
