Distal humerus intra-articular comminuted open fracture is a challenging injury, with nonunion, infection and stiffness considered as major concerns. We report a 58-year-old woman who was admitted to the emergency department from a car accident, sustaining an open wound with severe comminution of distal humerus and complete articular fracture, classified as AO/OTA 13C2 and Gustillo Anderson type IIIA. Debridement and external fixation was done first, followed by open reduction and internal fixation with fibular strut allograft. The patient showed excellent results in radiological and functional outcomes. Level of Evidence: Level V (Therapeutic).

BACKGROUND: People with achondroplasia exhibit distinct physical characteristics, but their cognitive abilities remain within the normal range. The challenges encountered during surgical procedures and perioperative care for achondroplastic individuals, are underrepresented in the existing literature.
METHODS: In this report, the management of a 26-year-old North-African achondroplastic male is highlighted. The patient suffered a complete intra-articular distal femur fracture (AO/OTA 33-C1) and an ipsilateral patella fracture (AO/OTA 34-C1). The patient\'s unusual anatomical variations and the lack of suitable orthopedic implants posed significant surgical challenges, particularly in the context of a resource-limited developing country. Facial and spinal deformities, which are common in patients with achondroplasia, further complicated the anesthetic approach.
CONCLUSIONS: The limited information on operative management of fractures in achondroplastic patients necessitated independent decision-making and diverging from the convenient approach where clear guidance is available in the literature.

BACKGROUND: Isolated unicondylar fractures of the distal femur are rare injuries, accounting for 3-6 % of adult femur fractures. The association with a femoral shaft fracture is very rare and, to our knowledge, has, never been described in the literature.
METHODS: In this article, we report the case of a 19-year-old motorcyclist involved in an accident, that resulted in both a midshaft transverse femoral fracture and an ipsilateral sagittal fracture of the medial femoral condyle (Trélat fracture).
UNASSIGNED: The surgical intervention involved open reduction and internal fixation for both fractures, utilizing a dynamic compression plate for the femoral shaft fracture and screws for the medial condyle fracture. Postoperative results showed excellent fracture reduction, and the patient progressed well with rehabilitation. The choice of fixation method for the sagittal medial femoral condyle fracture considered the unique anatomical challenges posed by this rare combination, the emergency (fat embolism), and the fact we didn\'t have a retrograde nail in our structure. A dynamic compression plate was used for femoral shaft fracture and screw fixation for condyle fracture treatment. The traction table in anterograde femoral nailing, led to the recurvatum of the condylar fracture and difficulty accessing it with the medial subvastus approach.
CONCLUSIONS: This case report adds a description of a rare combination and valuable insight into the management of complex femoral fractures, emphasizing the importance of individualized treatment approaches.

Articular fractures of the distal humerus are rare, and even rarer are fractures involving the trochlea and capitellum in a single fragment, with no associated comminution. These fractures are classified as 2a according to the Dubberley classification and are rarely described in the literature. Two cases of Dubberley 2a fractures were treated at our hospital. The first case, involving a 68-year-old patient, was treated with a medial and a lateral approach, combined with posteroanterior fixation using 3 Herbert screws. In the 2nd case, a 16-year-old male was treated with a single lateral approach, permitting fixation with two Herbert screws. One of the two screws is inserted into the bone at the edge of the cartilage, with an anteroposterior trajectory that leaves the cartilage intact. We opted mainly for posteroanterior screw fixation in subchondral bone, which is less damaging to articular cartilage and soft tissues and has already demonstrated its reliability. No associated lesions were found, and no complications were encountered. Results were excellent, with Mayo Elbow Performance Index (MEPI) scores of 95 and 100 respectively. Herbert screw fixation therefore appears to be an option of choice for these fractures, although comparative studies are needed to evaluate the different treatments available.

OBJECTIVE: To evaluate the outcome of displaced intraarticular calcaneal fractures (DIACFs) of a case series of patients who were treated with a percutaneous fixation technique.
METHODS: Eight patients were operated for DIACFs and they were evaluated for the outcome and complications in a mean follow up of 9 months (range: 6 - 12 months). At the last follow up the AOFAS score, the Boehlers\' angle and the presence of any complication were noted. The time from injury to surgery was also reported. The correlation of the AOFAS score and the development of post traumatic subtalar arthritis to the type of fracture, to the post operative Boehler\'s angle and to the time from injury to surgery were investigated.
RESULTS: The overall mean AOFAS (Americal Orthopaedic Foot and Ankle Society) score was 84,625 (Range: 73 - 96). The mean AOFAS score of type II and type III fractures was 87,667 and 75,500 respectively. The mean AOFAS score for fractures with a postoperative Boehler\'s angle of less than 10° and more or equal to 10° was 76,750 and 92,500 respectively. This difference was found to be statistically significant. The mean AOFAS score for fractures who were treated less or equal to six days and more than six days post injury was 91,250 and 78 respectively. Two out of four patients with a post operative Boehler\'s angle less than 10° developed post traumatic subtalar arthritis. No patient out of four for whom a Boehler\'s angle of more than 10° has been achieved, developed subtalar arthritis. No infection occurred in any of the patients.
CONCLUSIONS: Percutaneous fixation is a safe and effective way of treating DIACFs. The outcome is directly related to the quality of reduction, which is significantly dependent to the timing of surgery. The earlier the fracture is operated the better the reduction by closed means is.

UNASSIGNED: Intra-articular fractures represent a challenging group of injuries that can occur in many different locations. In addition to restoring the mechanical alignment and stability of the extremity, accurate reduction of the articular surface is a primary goal for the treatment of peri-articular fractures. A variety of methods have been deployed to assist in the visualization and subsequent reduction of the articular surface, each with a unique set of pros and cons. The ability to visualize the articular reduction must be balanced against the soft tissue trauma required for extensile exposures. Arthroscopic assisted reduction has gained popularity for the treatment of a variety of articular injuries. Recently, needle based arthroscopy has been developed, predominantly as an outpatient tool for the diagnosis of intra-articular pathology. We present an initial experience with and technical tricks for the use of a needle based arthroscopic camera in the treatment of lower extremity peri-articular fractures.
UNASSIGNED: A retrospective review of all cases where needle arthroscopy was used as a reduction adjunct in lower extremity peri-articular fractures at a single, academic, level one trauma center was performed.
UNASSIGNED: Five patients with six injuries were treated with open reduction internal fixation with adjunctive needle based arthroscopy. Early experience and tips and tricks for successful utilization of this technique are presented.
UNASSIGNED: Needle based arthroscopy may represent a valuable adjunct in the treatment of peri-articular fractures and warrants further investigation. Level of Evidence: IV.

BACKGROUND: Deep surgical site infection (SSI) may be a complication of open reduction and internal fixation (ORIF) of calcaneal fractures. This study aimed to describe the characteristics of patients with deep SSI following ORIF of calcaneal fractures via extensile lateral approach (ELA). We compared clinical outcomes of these patients, with a minimum follow-up of one year after successful treatment of deep SSI with a matched control group.
METHODS: In this retrospective case-control study, demographic data, fracture characteristics, bacterial pathogens, medical treatments and surgical approaches were collected, also the outcome was evaluated by the visual analog scale (VAS) for pain, foot function index (FFI) and AOFAS ankle-hindfoot score. The differences in Böhler and Gissane\'s angles between infected and contralateral feet were measured. By matching a control group of uninfected cases, clinical outcomes were compared between 2 groups using the Mann-Whitney U test.
RESULTS: Among 331 calcaneus fractures in 308 patients (mean age, 38.0 ± 13.1; male/female ratio, 5.5), 21 had deep SSI (6.3 %). There were 16 (76.2 %) males and 5 (23.8 %) females with a mean age of 35.1 ± 11.7 years. Thirteen (61.9 %) patients had unilateral fractures. The most common Sanders Type was found to be type II. The most frequent type of detected microorganisms was Staphylococcus species. Intravenous antibiotic therapy, mostly clindamycin, imipenem and vancomycin, based on the microbiological results, was prescribed with a mean±SD duration of 28.1 ± 16.5 days. The mean number of surgical debridements was 1.8 ± 1.3. Implants needed to be removed in 16 (76.2 %) cases. Antibiotic-impregnated bone cement was applied in three (14.3 %) cases. The clinical outcomes of 15 cases (follow up, 35.5 ± 13.8; range, 12.6-64.5 months) were 4.1 ± 2.0, 16.7 ± 12.3 and 77.5 ± 20.8 for VAS for pain, FFI % and AOFAS ankle-hindfoot score, respectively. Comparing with the control group (VAS for pain, 2.3 ± 2.7; FFI %, 12.2 ± 16.6, and AOFAS, 84.6 ± 18.0), only VAS pain was statistically lower in this group (p-value: 0.012). The differences in Böhler and Gissane\'s angles between both feet of infected cases were - 14.3 ± 17.9 and - 7.7 ± 22.5 (worse in the infected side), respectively.
CONCLUSIONS: Proper on-time approaches to deep infection following ORIF of calcaneal fractures may lead to acceptable clinical and functional outcomes. Sometimes aggressive approaches with intravenous antibiotic therapy, multiple sessions of surgical debridement, removal of implants and antibiotic impregnated cement are necessary to eradicate deep infection.
METHODS: Level III.

Displaced tongue-type calcaneus fractures are frequently associated with severe soft tissue injuries, and urgent relief of the displaced tongue fragment on the posterior soft tissues is essential to preventing soft tissue complications. If there is a complex articular injury, the soft tissue envelope often needs time for swelling to resolve to allow for a safe open anatomic reduction because premature open reduction internal fixation is often associated with increased complications. We have found that in high-energy tongue-type calcaneus fractures with complex articular injuries, a staged protocol consisting of initial percutaneous reduction and fixation with later definitive reconstruction is soft tissue friendly, allows early restoration of calcaneal morphology, and affords extensile approaches for eventual reconstruction. The purpose of this study was to describe our protocol of staged treatment of high-energy tongue-type calcaneus fractures, along with postoperative surgical outcomes, in a case series of 53 patients.Our series of patients had a high rate of intra-articular injury with marked initial displacement (mean Bohler angle -8.4 ± 20.8 degrees). They were treated initially with percutaneous reduction and fixation at median 1 day postinjury (interquartile range [IQR] 0-1) and definitively at median 16 days postinjury (IQR 10-33). In this series, 2 of 53 (3.8%) patients developed a deep wound infection.In high-energy tongue-type calcaneus fractures at risk for soft tissue compromise or with a significantly displaced tongue fragment without initial soft tissue compromise, we found that staged management represents a feasible management strategy to mitigate risk of soft tissue complications and therefore helps facilitate safe definitive open treatment.

The role of external fixation in Damage Control Orthopaedics has been well described. Temporary external fixation has been recommended to provide relative bone stability while the soft tissue heals, prior to formal open reduction and internal fixation. Temporary bridging external fixation, that spans the joint, is recommended as primary skeletal stabilization in complex intra-articular and peri-articular fractures, in extensive peri-articular soft-tissue damage around the knee, ankle, elbow and wrist joints. Works devoted to temporary trans-hip external fixation in treatment of complex high-energy injuries are relatively rare. The purpose of this article is to present our experience in using temporary hip spanning external fixation during primary treatment of six patients suffered from complex open intra-articular and peri-articular fractures of the proximal femoral bone with extensive soft tissue damage due to war blast or high-velocity gunshot trauma. Primary management was based on the concept of Advanced Trauma Life Support and Damage Control Orthopaedics. Conversion to definitive bone reconstruction was performed on the next stage of the treatment after general and local stabilization.

BACKGROUND: Femoral head fracture is a rare type of fracture commonly associated with hip dislocation. Femoral head fracture treatments include conservative treatment, fragment excision, open reduction, internal fixation, and arthroplasty. In cases of young patients, open reduction and internal fixation are preferred over arthroplasty. Pipkin type 2 fractures are treated with open reduction and internal fixation in most cases because the fracture line extends upward of the fovea and includes the femoral head-acetabular weight-bearing joint surface. However, if the fracture is severely comminuted or crushed, good results are difficult to obtain with open reduction and internal fixation.
METHODS: A 23-years-old male patient presented to the emergency room with right hip pain after 4-m fall.
METHODS: In initial image work up, he was diagnosed with right posterior hip dislocation and a Pipkin type 2 femoral head fracture with an ipsilateral superior ramus fracture. After manual reduction, simple radiography and computed tomography showed reduction of the hip joint and a large osteochondral defect of approximately 6 cm2 in the weight-bearing area on the superomedial side of the femoral head.
METHODS: This was treated with a novel surgery named autologous osteochondral transplantation (repositionplasty), devised by the authors.
RESULTS: The congruent reduction was confirmed by radiography and computed tomography immediately after the surgery. At 5 years postoperatively, the Harris Hip Score was 100 points and no discomfort, femoral head collapse, osteonecrosis, or traumatic arthritis were observed on follow-up radiographs.
CONCLUSIONS: We think this method \"repositionplasty\" will be a good treatment method for young patients with a large defect in the weight-bearing part of the femoral head who cannot undergo open reduction and internal fixation.
