C-Nail® locking nail versus conventional plate for thalamic calcaneal fractures.

BACKGROUND: Surgery for displaced intra-articular calcaneal fractures (DIACFs) is often followed by skin complications that adversely impacts the functional outcomes. Minimally invasive techniques have been developed to decrease the risk of skin complications. The objective of this study was to compare C-Nail® locking-nail fixation to conventional plate fixation for DIACFs. HYPOTHESIS: C-Nail® fixation restores calcaneal anatomy similarly to conventional plate fixation and decreases the frequency of skin complications compared to conventional plate fixation, while providing satisfactory functional outcomes. MATERIAL AND METHODS: In this case-control study of DIACFs, fixation was with a non-locking plate in 30 patients treated between January 2016 and June 2017 and with the C-Nail® in 25 patients treated between April 2017 and April 2018. Computed tomography was performed before surgery then bilaterally after surgery for measurements of the following calcaneal parameters: height, length, width, joint-surface step-off and inter-fragmentary distance. The values of these parameters were compared between the two groups. Postoperative skin complications were recorded. The functional outcome was assessed by determining the AOFAS score 1 year after the injury. RESULTS: The two groups showed no significant differences for age, sex or fracture type. Wound healing was delayed in 3 patients in the plate group. The mean postoperative values of the calcaneal parameters were not significantly different between the two groups. The mean AOFAS score was 85.3±10.4 (range, 50-100) in the plate group and 87.0±12.0 (range, 64-100) in the C-Nail® group (p>0.05). DISCUSSION: Minimally invasive C-Nail® fixation provides similar restoration of calcaneal anatomy as does conventional plate fixation. LEVEL OF EVIDENCE: III, retrospective case-control study.

Comparison of double screw fixation versus tension-band fixation after olecranon osteotomy for complex distal humerus fractures.

INTRODUCTION: Supra- and intercondylar elbow fractures are surgically challenging given the intra-articular comminution. Various surgical approaches have been described. Among these-olecranon osteotomy-provides optimal joint exposure but is associated with several complications. Tension band wiring (TBW) is the most commonly used fixation method. We hypothesized that double screw fixation would lead to fewer surgical revisions than TBW (all causes included) after olecranon osteotomy. METHODS: We carried out a single-center retrospective study of 39 patients, treated between January 2007 and April 2016, for a supra- or intercondylar elbow fracture using the transolecranon exposure. There were 34 type C fractures (13 C1, 6 C2 and 15 C3), 3 type B fractures and 2 type A fractures, based on the AO classification. Fourteen patients received double screw fixation and 25 received TBW. The primary outcome measure was the number of surgical revisions, regardless of cause. Secondary outcome measures were the number of surgical revisions for olecranon nonunion, fixation failure or fixation device removal due to pain. RESULTS: There were significantly more surgical revisions in the TBW group than in the double screw fixation group: 3 (21%) versus 14 (56%) (p=0.049, Fisher test). The three main reasons for revision in the TBW and double screw fixation groups were removal of the fixation device due to soft tissue impingement (11 [44%] versus 2 [14%]; p=0.08), failure of the olecranon fixation (6 [24%] versus 1 [7%] p=0.38), and olecranon nonunion (4 [16%] versus 0 [0%] p=0.27). DISCUSSION: There are no published studies on the outcomes of this surgical technique. The posterior transolecranon approach provides the best exposure at the elbow joint. TBW fixation is associated with multiple complications. Double screw fixation for olecranon fractures yields good clinical and radiological outcomes. CONCLUSION: Based on our findings, double screw fixation of the olecranon results in fewer surgical revisions (all causes combined) than TBW in supra- and intercondylar elbow fractures operated by a transolecranon approach.

Tibiotalocalcaneal fusion using the hindfoot arthrodesis nail: a multicenter study.

BACKGROUND: Tibiotalocalcaneal arthrodesis is a salvage option for severe ankle and hindfoot deformities, arthritis of the ankle and subtalar joints, avascular necrosis of the talus, failed total ankle arthroplasty, and Charcot arthropathy. This multicenter study reports clinical experience with the hindfoot arthrodesis nail (HAN) in the treatment of patients with severe ankle and foot abnormalities. METHODS: Seven participating clinics from Europe and North America recruited 38 patients who underwent ankle/subtalar arthrodesis using retrograde nailing with the HAN. Information was collected regarding technical details, complications, and functional and quality of life outcomes (Short Form-36 [SF-36], American Academy of Orthopaedic Surgeons-Foot and Ankle Outcomes [AAOS-FAO], and numeric rating scale [NRS] for pain) after an average of 2 years of follow-up. RESULTS: The rate of superficial wound infection was 2.4%. No deep soft tissue or bone infections were reported. The overall union rate was 84%. At the time of follow-up, low pain levels were reported, with a mean NRS of 2.2; the mean AAOS-FAO score was 38; and the SF-36 mean physical and mental health component scores were 41.2 and 52.5, respectively. All 13 patients who were unable to work prior to surgery were able to fully return to work. CONCLUSIONS: The HAN offered a safe and reliable salvage option for tibiotalocalcaneal arthrodesis in patients with severe ankle and hindfoot disease. It achieved acceptable functional outcome and low complication rates despite the challenging patient cohort. A considerable socioeconomic benefit appeared to result based on the high proportion of patients who were able to return to work postoperatively. LEVEL OF EVIDENCE: Level IV, retrospective case series.

History of the treatment of scapula fractures.

The history of treatment of scapula fractures is closely connected with the history of the French surgery. Paré (Les œuvres d´Ambroise Paré, conseiller, et premier chirurgien du Roy, Gabriel Buon, Paris, p VCV, 1579), Petit (Traité des maladies des os. Tome second, Charles-Etienne Hochereau, Paris, pp 122­138, 1723), Du Verney (Traité des maladies des os. Tome I, de Burre, Paris, pp 220­231, 1751) and Desault (Œuvres chirurgicales, ou tableau de la doctrine et de la pratique dans le traitement des maladies externes par Xav. Bichat, Desault, Méquignon, Devilliers, Deroi, Paris, pp 98­106, 1798) were the first to point out the existence of these fractures. The first drawing of a scapula fracture was presented by Vogt (Dissertatio de ambarum scapularum dextroeque simul claviculae fractura rara, Dissertatione Universitae Vitembergensi, Wittenberg, 1799). This author was also the first to describe the scapula fracture associated with ipsilateral fracture of the clavicle. The first radiograph of scapula fracture (glenoid fossa fracture) was published by Struthers (Edinburgh Med J 4(3):147­149, 1910). The first internal fixation of scapula fracture using plate was done by Lambotte (1910) who was followed by Lane (The operative treatment of fractures, Medical Publishing Co, London, pp 99­101, 1914) and later by Lenormant (Sur l´ostéosynthèse dans certains fractures de l´omoplate Bulletins et mémoires de la Société de chirgie de Paris, pp 1501­1502, 1923), Dujarier (Fracture du col chirgical de l´omoplate. Ostéosynthèse par plaque en T. Bonne réduction. Bulletin et mémoires de la Société de chirurgie de Paris, pp 1492­1493, 1923) and Basset (Ostéosynthèse d´une fracture de l´omoplate. Bulletin et mémoires de la Société nationale de chirurgie. p 193, 1924). Dupont and Evrard (J Chir (Paris) 39:528­534, 1932) presented the first detailed description of the surgical approach along the lateral border of the scapula including two drawings. They were also the first to use the term "pillar of scapula". Judet (Acta Orthop Belg 30:673­678, 1964) advocated operative treatment of displaced scapula fractures and described extensile posterior approach. Based on the French school, AO/ASIF improved methods of internal fixation of these fractures.

Integral classification of injuries (ICI) to the bones, joints, and ligaments--application to injuries of the foot.

The integral classification of injuries (ICI) is a very logical, descriptive classification of fractures and dislocations of the human skeleton. By enumerating all 28 foot bones in relation to the three anatomical and functional regions of the foot, ie, hindfoot (81), midfoot (82), forefoot (83), from proximal to distal, and by introducing lowercase letters for the joints of the foot skeleton,the localization of the injury can be described precisely. The uppercase A defines extra-articular, B describes intra-articular and C is for fracture dislocations. By introducing the uppercase D, different dislocations can be described. By using additional lowercase Greek letters, the direction of a dislocation can be coded. For simple 'everyday' use, a fracture of the calcaneus(81.2) involving three joints can be described as a B3-fracture. For scientific or database coding purposes, one can describe in square brackets which joints or segments are involved and how they are injured in relation to three different subgroups representing first the tissue (bone, cartilage, capsule, and ligaments),second the kind of injury (three graduations of fracture, cartilage, or ligament damage), and third (three graduations) the extent of the dislocation or displacement. Following ten conventions, a complex foot trauma can be coded as precisely as a simple dislocation of the big toe.

Central talar fractures--therapeutic considerations.

Talar fractures are rare and often have to be treated in the emergency department by young surgeons. Thus, important literature series, often multicentric, are generally of little interest regarding practical technical considerations. The aim of this paper is to lead the surgeon who has to treat such fractures to reflect on the goals of the treatment and the means to success. There is probably no better example than talar fractures for the application of the four AO basic principles: Anatomical reduction, stable internal fixation, preservation of the blood supply, and early active pain-free motion. After presenting the different approaches to the talus, the blood supply is described precisely, in reference to the surgical exposures. Then the many tools (tricks) to achieve the treatment goals, avoiding dangers and pitfalls, are meticulously described. Some of the goals, pitfalls, and tools are obvious, whereas some are not, but they could be just as important, if not more so.
