Project description:Although some literature may suggest that acute nondisplaced lesser tuberosity fractures should undergo nonoperative management, there is a body of evidence that supports surgical stabilization of these injuries due to concern for fracture displacement, nonunion and malunion, anteromedial impingement, and possible biceps tendon subluxation or dislocation. In this Technical Note, we introduce a novel technique for arthroscopic fixation of lesser tuberosity avulsion fractures using a knotless repair. In the lateral decubitus position using standard arthroscopic portals, with the addition of the biceps accessory portal, 2 ULTRATAPE sutures are fixed to the avulsed fragment in luggage-tag fashion to create a secure, knotless fixation. These are used to mobilize and anatomically approximate the lesser tuberosity to the avulsion bed and are held in place with suture anchors placed immediately adjacent to the fracture bed. This technique provides good anatomic reduction with maximal surface area for bone-to-bone healing.

Project description:Isolated fractures of the greater tuberosity of the humerus are an uncommon and frequently missed diagnosis. Mistreated and unrecognized, these fractures can cause chronic pain and diminished shoulder range of motion and function. Operative treatment options include open reduction and internal fixation, as well as arthroscopic-assisted reduction and internal fixation. The purpose of this Technical Note is to describe a bridging arthroscopic technique for the treatment of bony avulsions of the supraspinatus tendon.

Project description:Bicep tendon pathology often arises from chronic overuse injuries, acute trauma, or degenerative changes in the glenohumeral joint. These injuries can cause significant shoulder pain, and can greatly limit range of motion and, in turn, activities of daily living. The diagnosis of biceps pathologies can be challenging, because patients often present with nonspecific symptoms. Some bicep tendon pathologies may be treated nonoperatively; however, biceps tendon subluxation and the presence of rotator cuff or SLAP lesions require surgical management. One of the options for the treatment of bicep tendon pathology includes miniopen subpectoral biceps tenodesis. The purpose of this Technical Note is to describe in detail our preferred operative technique for miniopen subpectoral biceps tenodesis with 2 different fixation methods.

Project description:We report the use of the double-pulley technique for arthroscopic fixation of the bony PASTA (partial articular surface tendon avulsion) lesion. Arthroscopic examination documented a 15-mm-long and 8-mm-wide comminuted bony avulsion with 2 main fragments. Two double-loaded suture anchors were placed with a transtendinous technique at the anterior and posterior edges of the lesion respecting the tendon insertion to the avulsed fragment. The medial sutures were retrieved through the intact supraspinatus tendon medially to the fracture. The sutures were initially coupled in a double-pulley configuration generating 2 sutures oriented from anterior to posterior; then a simple suture for each anchor oriented from medial to lateral was obtained. At the end of the procedure, the adequacy of reduction and stability of the fragments were confirmed. At 2 months from surgery, radiographic healing of the fracture was noted and integrity of the supraspinatus tendon insertion to the footprint was confirmed by arthro-magnetic resonance imaging, with full recovery of daily activities and complete active range of motion confirmed at 6 and 12 months. The double-pulley technique allows optimal reduction of bony fragments and reconstruction of normal footprint anatomy even in comminuted fractures. Moreover, it creates a waterproof reduction of the fragments, protecting the fracture site from synovial fluid.

Project description:The fracture avulsion of the greater tuberosity (GT) represents 2% of all humerus fractures, but the true incidence is likely to be higher, being challenging the initial diagnosis on radiograph. The fracture avulsion of the GT could have different treatments: nondisplaced or minimally displaced fractures are treated conservatively, whereas for displaced or comminuted fractures surgical treatment is preferred. The most important finding of this study is the employment of an all-arthroscopic transosseous augmented technique for the treatment of a displaced humeral GT fracture avulsion. This technique shows all the advantages of the transosseous fixation and arthroscopic approach.

Project description:Avulsion fracture of the posterior cruciate ligament from its tibial insertion is a rare condition. Early surgical treatment has been regarded as necessary, but the optimal surgical technique remains unclear. The purpose of this technical note is to present a novel all-inside arthroscopic reconstruction technique for bony tibial avulsion fractures of the posterior cruciate ligament using the TightRope device (Arthrex, Naples, FL).

Project description:Bony avulsion fractures of the distal phalanges can result in mallet finger deformity if not treated appropriately. Therefore, only minimally displaced fractures can be treated conservatively with a good outcome, as dislocation occurs very often. Several surgical treatment options have been developed during the past decades. Data concerning the recently developed hook plate are promising. So far, no data concerning the subjective satisfaction with this method have been published. Therefore, we have analyzed the outcome after hook plate implantation using a self-assessment score, which focuses also on subjective parameters and satisfaction.Standardized questionnaires (self-assessment scores and SF-36 questionnaire) were sent to each patient treated with a hook plate due to fracture of the distal phalanx, type Doyle IVb and IVc. Clinical data were evaluated according to the medical record. Scores given per question range from 0 to 10, 10 is the worst and 0 the best outcome.From 69 patients treated, 38 (58%) were enrolled. The whole collective (n?=?38) reached a score of 39.7?±?28.7 points, while men had slightly better results. Men (n?=?24) achieved 37.3?±?27.9 points, women (n?=?14) 43.9?±?30.7 points. Women had significantly better results when analyzed later than 12 months after surgery (52.1?±?27.9 vs. 29.1?±?32.8), whereas no changes could be detected in the male group (37.1?±?29.9 vs. 37.4?±?27.6). Overall, men were slightly more satisfied than women. Most satisfaction was found regarding pain and fine motor skills (0-0.46 points). Esthetic aspect and nail deformities (3.65 points average) led to the highest dissatisfaction. No differences in the SF 36 score could be detected.The hook plate is not only a convenient method but it also results in high patient satisfaction. Nail deformities are challenging; however, with increasing experience of the surgeon they decrease. SF 36 score is not an appropriate testing tool for this problem.

Project description:Posterior wall blowout can be a devastating intraoperative complication in anterior cruciate ligament reconstruction. This loss of osseous containment can cause difficulty with graft fixation and can potentially lead to early graft failure if unrecognized and left untreated. If cortical blowout occurs despite careful planning and proper surgical technique, a thorough knowledge of the local anatomy and surgical salvage options is paramount to ensure positive patient outcomes. This article highlights our preferred salvage technique using suspensory cortical fixation with a screw and washer construct.

Project description:BACKGROUND:It is still unknown whether bioabsorbable magnesium (Mg) screws provide an advantage over titanium screws in the treatment of medial malleolar (MM) fractures. The purpose of this retrospective study is to compare the clinical and radiological outcomes of MM fractures fixed with either bioabsorbable Mg screws or conventional titanium screws. MATERIALS AND METHODS:A cohort of 48 patients with MM fractures who underwent compression screw fixation was retrospectively reviewed. Twenty-three patients (16 male, 7 female; mean age: 37.9?±?17.7 years) were treated with bioabsorbable Mg screws, and 25 patients (14 male, 11 female; mean age: 45.0?±?15.7 years) were treated with conventional titanium screw fixation. All patients were followed up for at least 1 year, with a mean time of 24.6?±?10.5 months (12-53 months). The American Orthopedic Foot and Ankle Society (AOFAS) scale was used to evaluate the clinical results. The Kellgren-Lawrence (KL) osteoarthritis grading was used to evaluate posttraumatic osteoarthritis on final ankle radiographs. Fracture union, rate of implant removal, and complications were recorded. Comparative analysis of two independent groups was performed using the chi-squared test and the Mann-Whitney U-test. RESULTS:The two groups were comparable concerning demographic and clinical characteristics. Age (p?=?0.146), sex (p?=?0.252), side (p?=?0.190), MM fracture type (p?=?0.500), associated fractures (p?=?0.470), and follow-up period (p?=?0.903) were similar between the groups. At final follow-up examination, AOFAS score (p?=?0.191) was similar between groups. Fracture union was achieved in all cases. Grade of posttraumatic osteoarthritis, according to KL, was equally distributed in both groups (p?=?0.074). No deep infection or osteomyelitis was seen. Five patients in the titanium screw group underwent implant removal, due to pain in three of them and difficulty in wearing shoes in the other two (p?=?0.031). Implant removal was performed after a mean of 14.2?±?3.1 months (12-19 months). CONCLUSIONS:Bioabsorbable Mg and titanium screws had similar therapeutic efficacy in MM fracture fixation regarding functional and radiological outcomes. However, the rate of implant removal was higher with titanium screws. Bioabsorbable Mg screws may be a favorable fixation option since secondary implant removal procedures can be prevented. LEVEL OF EVIDENCE:Level IV, Retrospective case series.

Project description:BackgroundFive different sacral fracture fixation methods were compared using finite element (FE) analysis to study their biomechanical characteristics.MethodsDenis type I sacral fractures were created by FE modeling. Five different fixation methods for the posterior pelvic ring were simulated: sacroiliac screw (SIS), lumbopelvic fixation (LPF), transiliac internal fixator (TIFI), S2-alar-iliac (S2AI) screw and S1 pedicle screw fixation (S2AI-S1) and S2AI screw and contralateral S1 pedicle screw fixation (S2AI-CS1). Four different loading methods were implemented in sequence to simulate the force in standing, flexion, right bending and left twisting, respectively. Vertical stiffness, relative displacement and change in relative displacement were recorded and analyzed.ResultsAs predicted by the FE model, the vertical stiffness of the five groups in descending order was S2AI-S1, SIS, S2AI-CS1, LPF and TIFI. In terms of relative displacement, groups S2AI-S1 and S2AI-CS1 displayed a lower mean relative displacement, although group S2AI-CS1 exhibited greater displacement in the upper sacrum than group S2AI-S1. Group SIS displayed a moderate mean relative displacement, although the displacement of the upper sacrum was smaller than the corresponding displacement in group S2AI-CS1, while groups LPF and TIFI displayed larger mean relative displacements. Finally, in terms of change in relative displacement, groups TIFI and LPF displayed the greatest fluctuations in their motion, while groups SIS, S2AI-S1 and S2AI-CS1 displayed smaller fluctuations.ConclusionCompared with SIS, unilateral LPF and TIFI, group S2AI-S1 displayed the greatest biomechanical stability of the Denis type I sacral fracture FE models. When the S1 pedicle screw insertion point on the affected side is damaged, S2AI-CS1 can be used as an appropriate alternative to S2AI-S1.
