Abstract Background Because of the broad anatomical variation in the course of the axillary nerve, several cadaveric studies have investigated the acromion-axillary nerve distance and its association with the humeral length to predict the axillary nerve location. This study aimed to analyze the acromion-axillary nerve distance (AAND) and its relation to the arm length (AL) in patients who underwent internal plate fixation for proximal humerus fractures.Methods The present prospective study involved 37 patients (15 female, 22 male; the mean age = 51 years, age range = 19 to 76) with displaced proximal humerus fractures who were treated by open reduction and internal fixation. After anatomic reduction and fixation was achieved, the following parameters were measured in each patient before wound closure without making an extra incision or dissection: (1) the distance from the anterolateral edge of the acromion to the course of axillary nerve was recorded as the acromion-axillary nerve distance and (2) the distance from the anterolateral edge of the acromion to the lateral epicondyle of the humerus was recorded as arm length. The ratio of AAND to AL was then calculated and recorded as the axillary nerve index.Results The mean AAND was 6 ± 0.36 cm (range = 5.5–6.6), and the mean arm length was 32.91 ± 2.9 cm (range = 24–38). The mean axillary nerve ratio was 0.18 ± 0.02 (range = 0.16 to 0.23). There was a significant moderate positive correlation between AL and AAND (p = 0.006; r = 0.447). The axillary nerve location was predictable in only 18% of the patients.Conclusion During the anterolateral deltoid-splitting approach to the shoulder joint, 5.5 cm from the anterolateral edge of the acromion could be considered as a safe zone for the prevention of possible axillary nerve injury.

Background: Surgical treatment of unstable syndesmotic injuries is not trivial, and there are no generally accepted treatment guidelines. The most common controversies regarding surgical treatment are related to screw fixation versus dynamic fixation, the use of reduction clamps, open versus closed reduction, and the role of the posterior malleolus and of the anterior inferior tibiofibular ligament (AITFL). Our aim was to draw important conclusions from the pertinent literature concerning surgical treatment of unstable syndesmotic injuries, to transform these conclusions into surgical principles supported by the literature, and finally to fuse these principles into an evidence-based surgical treatment algorithm. Methods: PubMed, Embase, Google Scholar, The Cochrane Database of Systematic Reviews, and the reference lists of systematic reviews of relevant studies dealing with the surgical treatment of unstable syndesmotic injuries were searched independently by two reviewers using specific terms and limits. Surgical principles supported by the literature were fused into an evidence-based surgical treatment algorithm. Results: A total of 171 articles were included for further considerations. Among them, 47 articles concerned syndesmotic screw fixation and 41 flexible dynamic fixations of the syndesmosis. Twenty-five studies compared screw fixation with dynamic fixations, and seven out of these comparisons were randomized controlled trials. Nineteen articles addressed the posterior malleolus, 14 the role of the AITFL, and eight the use of reduction clamps. Anatomic reduction is crucial to prevent posttraumatic osteoarthritis. Therefore, flexible dynamic stabilization techniques should be preferred whenever possible. An unstable AITFL should be repaired and augmented, as it represents an important stabilizer of external rotation of the distal fibula. Conclusions: The current literature provides sufficient arguments for the development of an evidence-based surgical treatment algorithm for unstable syndesmotic injuries.

Even though fifth metatarsal fractures represent one of the most common injuries of the lower limb, there is no consensus regarding their classification and treatment, while the term ‘Jones’ fracture has been used inconsistently in the literature. In the vast majority of patients, Zone 1 fractures are treated non-operatively with good outcomes. Treatment of Zone 2 and 3 fractures remains controversial and should be individualized according to the patient’s needs and the ‘personality’ of the fracture. If treated operatively, anatomic reduction and intramedullary fixation with a single screw, with or without biologic augmentation, remains the ‘gold standard’ of management; recent reports however report good outcomes with open reduction and internal fixation with specifically designed plating systems. Common surgical complications include hardware failure or irritation of the soft tissues, refracture, non-union, sural nerve injury, and chronic pain. Patients should be informed of the different treatment options and be part of the decision process, especially where time for recovery and returning to previous activities is of essence, such as in the case of high-performance, elite athletes.

Background Open reduction and internal fixation (ORIF) of humeral head split fractures is challenging because of high instability and limited visibility. The aim of this retrospective study was to investigate the extend of the approach through the rotator interval (RI) on the reduction quality and functional outcome. Methods 37 patients (mean age: 59  ±  16 years,16 female) treated by ORIF through a standard deltopectoral (DP) approach were evaluated. The follow-up period was at least two years. In 17 cases, the approach was extended through the RI. Evaluation was based on radiographs, Constant scores (CS) and DASH scores. Results In group DP, “anatomic” reduction was achieved in 9 cases (45%), “acceptable” in 5 cases (25%), and “malreduced” in 6 cases (30%). In group RI, “anatomic” reduction was seen in 12 cases (71%), “acceptable” in 5 cases (29%), and “malreduced” in none (p  =  0.04). In the DP group, the CS was 60.2  ±  16.2 and the %CS was 63.9  ±  22.3, while in the RI group, the CS was 74.5  ±  17.4 and the %CS was 79.1  ±  24.1 (p  =  0.07, p  =  0.08). DASH score was 22.8  ±  19.5 in DP compared to RI: 25.2  ±  20.6 (p  =  0.53). Conclusions The RI approach improves visualization as it enhances quality of fracture reduction, however functional outcomes may not differ significantly.

Background: The stability of the syndesmosis is extremely important in terms of syndesmosis injury, ankle instability, and posttraumatic osteoarthritis development following ankle fractures. The aim of this study is to evaluate 1-year radiographic outcomes after posterior malleolar fixation in lateral and posterior malleolar fractures and trimalleolar fractures without transsyndesmotic screw fixation. Methods: Ninety-four patients who underwent posterior malleolar fixation with posterolateral approach between January 2017 and June 2019 were evaluated retrospectively. The patients were evaluated with parameters such as demographic characteristics, fracture type, injury mechanism, physical examination, and radiographic measurements. The stability of the syndesmosis was evaluated by an intraoperative Cotton test and by measuring the tibiofibular overlap, tibiofibular clear space, and medial clear space parameters preoperatively on the immediate postoperative, first-year weightbearing ankle anteroposterior radiographs. Results: In immediate postoperative measurements on radiographs, although the mean tibiofibular overlap ( P < .001) increased, the mean tibiofibular clear space ( P < .001) and mean medial clear space ( P < .001) decreased compared with preoperative radiographs. Immediate postoperative mean tibiofibular overlap, tibiofibular clear space, and medial clear space compared with postoperative first-year mean tibiofibular overlap ( P = .39), tibiofibular clear space ( P = .23), and medial clear space ( P = .43) were not statistically significant. Bone union was completed radiographically at a median of 3.4 ± 1.8 months after surgery. Conclusion: After posterior malleolar fractures, anatomic reduction of the posterior malleolus and posterior inferior tibiofibular ligament complex provides strong syndesmosis stability as measured radiographically at 1 year. Patients may not need additional transsyndesmotic screw fixation. Level of Evidence: Level IV, case series.

Background:- Fractures of the talus are unusual, and talar body fractures in the sagittal plane are still rarer. Its treatment aims a crucial anatomic reduction to reimpose congruency of the ankle and decrease the risk of avascular necrosis by conserving any remaining blood supply. We present the case of a body talar fracture in the sagittal plane related to fracture of the medial malleolus in an adult. The mechanism of the fracture was, internal rotation, plantar hyperexion, and axial compression. We performed an open reduction and stabilization with two screws for the talus and screwed the medial malleolus. Material & Methods:- We included 30 patients in this study among which a 25 years old man presented in Department Of Orthopaedics, Mgmmch, Jamsehedpur, Jharkhand with a grossly expand and deformed right ankle. Radiographs revealed a displaced vertical fracture of the neck of the talus traversing through the body with vertical fracture of the medial malleolus and medial talar shift. Results:- Fractures of the talus have a relatively little incidence accounting for 0.3% of all bone fractures and 3% to 6% of all foot fractures.[1,2] Union of the fracture in such a case is extremely slow as it depends on a new blood supply growing into the avascular bone.[3] Hence, the fracture needs preservation for a long time, and non-weight bearing is recommended for three months or until the union has occurred. Malunion can produce substantial alteration in load across the ankle and subtalar joints and result in arthrosis. The reported case should have the best prognosis as it was closed and underwent immediate operative reduction with early signs of revascularization. After 13 months following the injury, the patient had the best range of movement with some pain. Conclusion:- Talar body fracture associated with ankle fracture is very rare. Still, the malleolar fracture that allows adequate visualisation, anatomical reduction, and appropriate fracture xation can give us hope to reduce complications.

Abstract Background Various plate shapes and implant configurations are used for stabilization of acetabulum fractures via anterior approaches. Little is known about the biomechanical stability of a two-dimensionally shaped “conventional” plate (“J-Plate”—JP) in comparison to three-dimensionally shaped plate configurations (3DP). In addition, the augmentary effect of an infra-acetabular lag-screw (IACS) fixation for anterior column and posterior hemi-transverse acetabulum fractures has not been clarified in comparison of JP and 3DP constructs. This study analyzed the difference between the biomechanical stability of JP compared to 3DP and the role of an IACS in a standardized acetabular fracture model in a single-leg stance loading configuration. Methods In an artificial bone substitute pelvis model (Synbone© Malans, Switzerland), a typical and standardized fracture pattern (anterior column and posterior hemi-transverse) was created with osteotomy jigs. After anatomic reduction the stabilization was performed using JP or 3DP. Eight pelvises per group were axially loaded in a single-leg stance model up to 400 N. After the load cycle, an additional infra-acetabular screw was placed and the measurement repeated. Fragment displacement was recorded by an optical tracking system (Optitrack Prime 13®, Corvallis, USA). Results In the pure placement, 3DP provided significantly superior stability when compared to JP. Augmentation of JP by IACS increased the stability significantly, up to the level of 3DP alone, whereas augmentation of the 3DP did not result in further increase of overall stability. Conclusion The anatomically shaped plate alone provides a superior biomechanical stability in fixation of an anterior column and posterior hemi-transverse fracture model. In a JP fixation the augmentation by IACS provides similar strength as the anatomically shaped 3DP. By use of the anatomically shaped 3DP the need of a clinically risky application of IACS might be avoidable. Level of evidence IV, Experimental study.

Objective: The Objective of this study is to analyze the radiological, clinical and functional outcome of patients with acute unstable scaphoid fracture treated with primary bone grafting and K (Kirschner)-wire fixation Methods:Based on inclusion and exclusion criteria , a prospective observational study was carried out on 21 patients with acute unstable  scaphoid fracture who had been treated with primary bone grafting and K-wire fixation from November 2017 to March 2020 and were followed up for a minimum of 24 weeks. The average patient age was 26.9 years. The time from injury to treatment averaged 11days. Surgery was done under Bier’s Block using volar approach. Bone graft was harvested from distal Radius. The mean operating time was 24 minutes.Clinical parameters like tenderness, grip strength and Range of Movement (ROM) at wrist was assessed. The functional outcome was evaluated using Modified Mayo wrist score. Bone union was assessed using serial plain radiographs. Results:Union was achieved in all (100%) at 12 weeks. There was no evidence of Avascular necrosis (AVN) or arthrosis at latest follow up. As per Modified Mayo wrist score, there were 15 excellent,03 good and 03 fair results at the final follow-up. Individuals resumed their routine work at 12 weeks and all were comfortable with heavy works/ sports activity by 24 weeks. Conclusion: Primary bone grafting has a definite role in the management of acute unstable scaphoid fracture by which aquicker and higher rate of union isachieved with minimal complications. Open reduction allows thorough assessment of fracture for better anatomic reduction. Although the type of fixation device hardly contributes for quicker and higher union, but then the use of K-wire for fixation is the only viable option for smaller bony fragments and is more forgiving in terms of its positioning. It has an added advantage in terms of requirement of minimal inventory and thus is a cost-effective modality. This procedure also confirms that the patients could get back to their work earlier hence decreasing economic burden.

Abstract Introduction Tibial plafond fractures (TPF) are uncommon but potentially devastating injuries to the ankle. Meticulous care of the associated soft tissue injury is imperative in managing these fractures. The reported benefits of circular external fixation (CEF) include the ability to affect fracture reduction and create stable fixation, while limiting further soft tissue insult. This article provides the systematic review of the clinical and functional outcomes of TPF treated definitively with CEF. Method A literature search from inception to 13th November 2020 was performed. Quality and risk of bias was assessed using standardised scoring tools. Results 16 studies were included. 303 patients were analysed. Mean follow-up was 35 months. The mean time in CEF was 18 weeks and mean time to union was 21 weeks. Non-union and malunion occurred in 3.2% and 12.4% respectively. The overall complication rate was 12.3%. The rate of deep infection was 4.8%. No amputations were reported. Minor soft tissue infection (including pin site infections) accounted for 56.7% of complications. Almost two-thirds achieved good-to-anatomic reduction radiologically. Mean range of motion assessments were 11.8 and 24.8 degrees in dorsiflexion and plantarflexion, respectively. Approximately one-third reported excellent functional outcome scores. Quality of the studies was deemed satisfactory. A moderate risk of bias was acknowledged. Conclusions This systematic review provides an evidence-based summary, which highlights CEF as an acceptable treatment option with comparable complication rate and outcome scores to that of internal fixation. However, we acknowledge that high quality evidence is still lacking.
