OBJECTIVE: To evaluate outcomes and complication rate of utilizing a string-of-pearls (SOP) plate augmented with adjunctive fixation in the repair of canine femur fractures.
METHODS: Records of canine patients with mid-diaphyseal femoral fractures repaired with the SOP plate and adjunctive fixation were reviewed. Information retrieved from medical records included signalment, patient weight, fracture configuration, repair technique, healing time, and complications based on perioperative radiographic follow-up to clinical union. Forty client-owned dogs met inclusion criteria for this study. Variables analyzed for association with major complications included body weight, fracture configuration, repair technique, and adjunctive fixation.
RESULTS: Major complications requiring surgical revision occurred in 8 of 40 fractures. Five cases experienced intramedullary pin migration and were successfully treated with sedated pin removal. The remaining 3 cases involved implant failure via screw shear breakage and required surgical revision of the fixation to achieve a successful outcome. On the basis of a calculated Bonferroni correction, no statistical significance of the tested variables was found in association with major complications; however, significance was limited due to the low statistical power of this study.
CONCLUSIONS: The use of adjunctive fixation with the SOP locking plate system led to radiographic union without complication in most cases, and no instances of plate breakage were reported. However, implant complications secondary to the adjunctive fixation can occur.
CONCLUSIONS: Adjunctive fixation used with the SOP plate for repair of canine femur fractures has a high success rate, though pin migration as a complication persists.

BACKGROUND: Due to its unique anatomical characteristics, supracondylar fractures of the humerus are often difficult to achieve firm fixation with internal fixation equipment, resulting in delayed functional exercise, often leaving cubitus varus deformity, elbow stiffness, contractures, and other complications. Here, we report an adult patient with a supracondylar fracture of the humerus who underwent internal fixation through an anterior median incision in the humerus with our self-developed anterior anatomical locking plate of the distal humerus.
METHODS: A 29-year-old male patient of Chinese ethnicity with trauma-induced right supracondylar fracture of the humerus and multiple soft tissue contusions, without nerve damage, blood vessel damage, or other injuries, underwent an internal incision in our hospital using a new anatomical locking plate for the anterior distal humerus fixed treatment. During the 16-month follow-up period, the patient\'s elbow range of motion was almost completely restored, functional scores were excellent, and there were no minor or major postoperative complications.
CONCLUSIONS: In this study, we propose a surgical reconstruction strategy for adult patients with supracondylar humeral fractures. Through the anterior median incision of the humerus, open reduction and internal fixation were performed with an anatomic locking plate on the anterior side of the distal humerus to restore and fix the structure of the distal humerus, and satisfactory clinical results were achieved in our case.

Isolated fractures of the distal fibula mainly affect young, active people. In most cases, fixation is by open reduction with or without casting for six weeks without weight bearing. The current trend is to reduce this period of non-weight-bearing in order to promote earlier functional rehabilitation. The improved mechanical stability resulting from the use of plates with locking screws has changed the postoperative management of many fractures, but there is little evidence for the ankle. Between October 2013 and August 2015, 36 patients were enrolled in a prospective study to evaluate the performance of internal fixation of isolated distal fibular fractures using a lateral anatomically contoured titanium locking plate (InitialA® plate from Newclip Technics, Haute Goulaine, France) with immediate mobilisation and full weight bearing. No patient required further surgery due to mechanical failure or non-union. The bone healing rate was 100 % at 3 months. Two patients had septic complications requiring plate removal and antibiotic treatment and were eventually cured. The use of anatomically contoured locking plates provides strong and stable fixation, allowing immediate full weight-bearing. Such a technique has the advantage of a short recovery time and an early return to work without additional complications.

BACKGROUND: Treatment of proximal tibial fractures is known to be difficult. We report our own experience of the treatment of these fractures and evaluate our results. The hypothesis was that the clinical and radiological results were good.
METHODS: From January 2004 to October 2008, fourteen AO-type 41A2-3 and C1 fractures have been treated with a LCP locking plate (8 women and 6 men, average age 60.42). Plating was performed either with an open approach or a minimal invasive approach. Clinical and radiological follow-up was carried out looking for range of motion of the knee joint and autonomy level.
RESULTS: Mean follow-up was 32.63 months (12-70). Range of motion was maintained with a mean arch of 117.5° Autonomy was maintained in all cases. Professional, domestic and sports activities were unchanged. No infection or general complication occurred. Bone fusion was obtained in all cases after an average of 13.28 weeks. 6° of valgus deformation, already seen immediately postoperatively was observed once. Secondary displacement was observed in 6 cases, with an average of 2.83° DISCUSSION-CONCLUSION: We report good radiological results, with only one initial malalignment. The hypothesis was confirmed. However, X-ray analysis at consolidation shows 6 secondary displacements, without any satisfactory explanation. Though the clinical consequences of these malunions are minimal. Osteosynthesis with plate, in the sight of this study, yields good clinical results. Radiological evolution concerning the evolution of bone axes puts the emphasis on careful operative technique and adequate time to weight bearing.
METHODS: retrospective study, IV.

BACKGROUND: The calcar of the proximal humerus is a fundamental structure for medial humeral column support. This study aimed to assess the outcome of osteosynthesis across cases of unstable proximal humerus fractures (PHFs) with medial calcar comminution, following treatment with a PHILOS locking plate and medial support screw (MSS).
METHODS: Between January 2010 and December 2018, we retrospectively analyzed the outcomes of 121 cases of osteosynthesis for PHFs with medial column disruption. For the medial support, at least one oblique screw was inserted within 5 mm of the subchondral bone in the inferomedial quadrant of the humeral head. All patients were categorized into two groups: 26 patients in the single MSS group, and 95 in the multiple MSS group. Follow-up after at least an year involved clinical and radiographic outcome evaluations, and correspondingly measuring the Constant-Murley score, University of California, Los Angeles (UCLA) shoulder scale, pain visual analogue scale (VAS), major complications, neck-shaft angle (NSA), humeral head height (HHH), and the eventual time to bone union. Risk factors for the major complications were assessed by multivariate logistic regression analyses.
RESULTS: The cohort\'s mean age was 64.4 ± 15.4 years, and the mean follow-up duration was 19.5 ± 7.6 months. At the final follow-up, between the single MSS and multiple MSS groups, no significant differences in the Constant-Murley score (p = 0.367), UCLA score (p = 0.558), VAS (p = 0.571), time to bone union (p = 0.621), NSA loss (p = 0.424), and HHH loss (p = 0.364) were observed. The incidence of complications (p = 0.446) based on the number of MSS were not significantly different. The initial insufficient reduction after surgery (of NSA < 125°) was found to be a significant risk factor for post-surgical complications.
CONCLUSIONS: To treat unstable PHFs, the use of at least one MSS along with a locking plate system is sufficient to achieve satisfactory outcomes. Successful operative treatment using a locking plate for PHF treatment is inherent in anatomical fracture reduction, coupled with medial column support.

Background/Objectives: Intramedullary screw fixation (IMS) and locking plate fixation (LPF) are currently recommended treatments for proximal fifth metatarsal fractures (PFMF). However, treating comminuted or small displaced avulsion PFMF with IMS poses challenges due to complications. A novel alternative fixation method, the locking compression plate for distal ulna hook plate fixation (LPF), has been introduced recently for distal ulna fractures and has shown improved clinical results. This scoping review aims to assess whether LPF yields superior outcomes, such as postoperative AOFAS scores and rate of postoperative complications, compared to IMS in PFMF treatment. Methods: This review included randomized controlled trials (RCTs), prospective cohort studies, retrospective cohort studies, or case series involving patients with PFMF who underwent plate fixation or screw fixation. The primary outcome was the postoperative American Orthopedic Foot and Ankle Society (AOFAS) score. Studies were sourced from databases including PubMed, Embase, and Scopus, with the search conducted up to February 2024. The Systematic Review protocol was registered in the CRD PROSPERO database (CRD42024532593). Results: Ten studies were included, comprising 3 cohort studies, 1 case-control study, and 6 case series, with a total of 309 patients (158 with LPF and 142 with IMS). The postoperative AOFAS scores showed no significant difference between LPF and IMS in treating PFMF. However, LPF demonstrated efficient surgical procedures and enhanced functional outcomes. Complications were minimal in both groups, with no significant difference in the rate of postoperative complications. Conclusions: Although there was no significant difference in AOFAS scores between LPF and IMS, LPF demonstrated efficient surgical procedures and enhanced functional outcomes, making it a reasonable alternative method for PFMF. Effective shared decision-making (SDM) with patients becomes paramount in choosing the optimal surgical approach. In the surgical landscape, thoughtful deliberation, patient engagement, and adherence to biomechanical principles are crucial for achieving successful outcomes in the treatment of PFMF.

UNASSIGNED: Non-union is a complex, multifactorial orthopaedic problem that requires multiple treatment modalities for its management. It can result from infection, segmental bone loss, soft-tissue loss, and associated host factors. External fixators as management of gap non-union are bulky and give rise to a number of complications In our study, we have described a technique where we have used extramedullary fixation in the form of a tibial locking plate and transportation of part of the tibial bone after corticotomy by a monorail fixator.
UNASSIGNED: The procedure was done in two stages where internal and external fixation was done after creating a gap at the non-union site. The bone was transported after corticotomy and fixed to the internal fixation device in the second stage. The external fixator was removed in the second stage and the patient was then followed up till the bony union. The evaluation was done by functional and radiological assessment along with the complications noted with the described procedure.
UNASSIGNED: Ten patients were enrolled in the study with a mean age of 33 years. The mean age of the patients was 33.7 ± 11.32 years with a mean size of the defect was 4.8 ± 1.7 cm. At 30 weeks out of nine patients, three patients had excellent and six had good functional results on the Association of Surgeons for Application and Methodology of Ilizarov (ASAMI) scale. The composite Musculoskeletal Tumor Society (MSTS) score was 76.66 % at the end of 30 weeks of follow-up. The mean time of consolidation was 134.4 days, whereas the mean union time was 145 days from index surgery. Ankle stiffness was the most common complication affecting 50% of the patients. Following closely was pin tract infection, which was present in 40% of the patients. According to Paley\'s classification, there were 11 obstacles, two problems and none were true complications.
UNASSIGNED: The integrated fixation is both safe and effective and has the advantage of early removal of the external fixator and a low complication rate as compared to use of a bulky conventional fixator alone. Moreover, it gives protection to the regenerated bone for a long period. So, this technique can be recommended for the management of segmental tibial defects.

OBJECTIVE: This study compared outcomes of locked plating (LP) versus intramedullary nailing (IMN) techniques for treatment of extra-articular proximal-third tibia fractures.
METHODS: Data Sources: PubMed, Ovid MEDLINE STUDY SELECTION: Studies were included if they compared LP and IMN fixation for proximal one third tibial shaft fractures without articular extension or with simple articular extension into the tibial plateau. Minimum 1 year of clinical and radiographic follow up was used.
METHODS: Outcomes assessed included operative duration, postoperative knee range of motion (ROM), union outcomes (time to union, nonunion, malunion, delayed union), and incidence of postoperative complications (superficial and deep infection, secondary surgical intervention, compartment syndrome).
RESULTS: Separate random-effects meta-analyses were conducted for each outcome. For categorical data, relative risks were used whereas the standardized mean difference was used for continuous variables, with corresponding 95 % confidence intervals.
RESULTS: 7 studies were included reporting the outcomes of 319 patients treated with LP and 300 treated with IMN. IMN fixation had significantly shorter time to union (p = 0.049) and lower risk for superficial infection (p = 0.028). However, LP conferred a significantly lower risk for malunion (p = 0.017) and postoperative compartment syndrome (p = 0.018).
CONCLUSIONS: IMN demonstrated significantly shorter time to union and lower risk of superficial infection when treating extra-articular proximal tibia fractures, while LP fixation demonstrated significantly lower risk for malunion and postoperative compartment syndrome. Although successful results can be achieved with good technique in LP and IMN fixation, a significant complication profile exists with these fractures regardless of construct choice.
METHODS: Therapeutic Level III.

To the best of our knowledge, there are no reports in the literature of an open comminuted scaphoid fracture dislocation. We present such a rare case. The case report illustrates the case of a 58-year-old right-handed press operator who injured his left wrist when his hand got caught in a press machine. He received initial treatment at another hospital and was subsequently referred to our hospital. Eight days after the injury, surgery was performed under the brachial plexus block. Successful bone fusion was achieved through volar locking plate fixation, primary free bone grafting from the radius, and Kirschner wire fixation. Our case report may be a valuable resource for the treatment of similar injuries.

BACKGROUND: The aim of this study was to explore the efficacy of a novel intramedullary fixation technique using the ortho-bridge system (OBS) for midshaft clavicle fractures.
METHODS: A total of 63 patients were included in this study: 35 underwent plate internal fixation (LP group) and 28 underwent OBS intramedullary fixation (OBS group). Surgical time, intraoperative blood loss, incision length, fracture healing time, removal of the internal fixation agent, visual analog scale (VAS) score for shoulder pain, Constant-Murley shoulder score and complication occurrence were compared between the two groups.
RESULTS: Preoperative general data, such as sex, age and fracture type, were not significantly different between the two groups (P > 0.05). However, the OBS group exhibited better outcomes than the LP group exhibited in terms of surgical time, intraoperative blood loss and total incision length (P < 0.05). Additionally, the OBS group exhibited a significantly shorter fracture healing time and internal-fixation removal time than the LP group exhibited (P < 0.05). The VAS scores on postoperative day 1, week 1, month 1 and month 3 were lower in the OBS group than in the LP group (P < 0.05). Furthermore, the Constant-Murley shoulder scores at 1, 3, and 6 months postoperatively were higher in the OBS group than in the LP group (P < 0.05), with no significant difference at 1 year after surgery (P > 0.05). None of the patients in the OBS group experienced scarring of the surgical incision, and 6 patients in the LP group experienced scarring of the surgical incision. Finally, the complication incidence in the OBS group was lower than that in the LP group.
CONCLUSIONS: For midshaft clavicle fractures, OBS intramedullary fixation is better than locking-plate internal fixation because it led to less trauma, a faster recovery, better efficacy, and better esthetic outcomes and comfort. Therefore, this technique may have potential as a novel treatment for midshaft clavicle fractures.
METHODS: III, retrospective observational study.
