Project description:Background Proximal row carpectomy (PRC) and four-corner arthrodesis (4-CA) represent motion-sparing procedures for addressing degenerative wrist pathologies. While both procedures demonstrate comparable functional outcomes, postoperative pain presents a surgical challenge that often necessitates the use of opioids. Objectives The aim of this study was to (1) compare opioid prescribing patterns surrounding PRC and 4-CA, (2) identify risk factors predisposing patients to increased perioperative and prolonged postoperative opioids, and (3) examine the association between opioids and perioperative health care utilization. Patients and Methods PearlDiver Patients Records Database was used to retrospectively identify patients undergoing primary PRC and 4-CA between 2010 and 2018. Patient demographics, comorbidities, prescription drug usage, and perioperative health care utilization were evaluated. Perioperative opioid prescriptions and post-operative opioid prescriptions were recorded. Logistic regression analysis evaluated the association of patient risk factors. Results There was no significant difference in perioperative (PRC [odds ratio {OR}: 0.84, p = 0.788]; 4-CA [OR: 0.75, p = 0.658]) or prolonged postoperative opioid prescriptions (PRC [OR: 0.95, p = 0.927]; 4-CA [OR: 0.99, p = 0.990]) between PRC and 4-CA. Chronic back pain and use of benzodiazepines or anticonvulsants were associated with increased risks of prolonged postoperative opioids. Prolonged postoperative opioids presented increased risks of emergency department visits (OR: 2.09, p = 0.019) and hospital readmissions (OR: 10.2, p = 0.003). Conclusion No significant differences exist in the prescription of opioids for PRC versus 4-CA. Both procedures have high amounts of prolonged postoperative opioid use, which is associated with increased risks of emergency department visits and hospital readmissions. Level of Evidence This is a level III, retrospective comparative study.

Project description:Surgical fusion of the subtalar joint is a procedure indicated to alleviate pain of subtalar origin, such as in post-traumatic osteoarthritis, adult-acquired flatfoot deformity, and other disorders. Open subtalar arthrodesis has been performed with predictable results, but concerns exist regarding injury to proprioception and local vascularity due to wide surgical dissection. Minimally invasive techniques try to improve results by avoiding these issues but have a reputation for being technically demanding. We describe the surgical technique for arthroscopic subtalar arthrodesis, which has proved to be a safe and reliable technique in our experience, with consistent improvements in American Orthopaedic Foot & Ankle Society scores.

Project description:The effectiveness of subtalar arthrodesis has been well documented in treating degenerative subtalar joint disease. The arthroscopic subtalar approach for arthrodesis has also been proved to give excellent results in terms of bone fusion rates and reduction of wound-related pain and complications. To date, the main concerns about arthroscopy have regarded incision-related neurologic complications such as lesions of the tibial, fibular, and sural nerves. In this context, we present a 2-portal lateral (anterior and middle) approach to arthroscopic subtalar arthrodesis, recently documented in the literature, that provides similar excellent access to the joint with a lower risk of nerve damage.

Project description:Resection of symptomatic talocalcaneal coalitions (TCCs) has been performed for patients with normal tarsal joints and <50% involvement of the subtalar joint. For those with TCCs >50% of subtalar articulation or/and subtalar arthritis, a subtalar arthrodesis is done. The purpose of this Technical Note is to describe the arthroscopic resection of TCC and talocalcaneal arthrodesis during the same procedure by using a 2 lateral portal technique. With the patient in lateral decubitus under general or locoregional anaesthesia, the foot and ankle are extended beyond the edge of the surgical table. A lateral portal is created 1 cm anterior to the tip of the lateral malleolus in which the arthroscope is introduced. The anterolateral portal is created 1 cm inferior and 2 cm anterior to the tip of the lateral malleolus. The posterior subtalar surface is prepared progressively. The TCC resection is completed. The fixation is obtained with 2 cannulated screws. The arthroscopic resection of TCC and subtalar arthrodesis during the same procedure by using 2 lateral portals can be done for correctly selected patients.

Project description:Introduction Four-corner arthrodesis with excision of the scaphoid is an accepted salvage procedure for scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) and has been performed in our unit for over 20 years. We have undertaken a retrospective review of 116 of these procedures performed in 110 patients between 1992 and 2009. Fifty-eight patients attended for a clinical evaluation, and 29 responded by postal questionnaire. Methods The surgical technique undertaken was standard. That is, through a dorsal approach the scaphoid and tip of the radial styloid were excised. The capitate, lunate, triquetrum, and hamate articular surfaces were then prepared down to bleeding bone. Bone grafts from the scaphoid and radial styloid were then inserted and fixation undertaken. For the latter, various methods were used, including Kirschner (K-)wires, staples, bone screws, but predominantly the Spider plate (Integra Life Sciences, USA). Thereafter the wrist was immobilized for a minimum period of 2 weeks prior to rehabilitation. Results Follow-up was done at a mean of 9 years and 4 months (range 3-19 years). All patients reported a significant improvement in pain relief and ∼50% of flexion extension, although only 40% of radioulnar deviation. Grip strength was again ∼50% of the contralateral side. Most patients reported a significant improvement in function with 87% returning to work. In addition, radiologic evaluation identified 28 patients (31%) who demonstrated ongoing signs of nonunion, particularly around the triquetrum. Fourteen of these (15%) underwent a further procedure, generally with success. Finally, none of the patients demonstrated any arthritic changes in the lunate fossa on follow-up X-ray, and all secondary procedures were undertaken within 2 years of the primary. Discussion This research has demonstrated that four-corner fusion fixed with a circular plate can result in a satisfactory outcome with a reduction in pain, a functional range of motion, and a satisfactory functional outcome. The bulk of the complications appear to occur in the first 2 years after surgery. Thereafter, analysis shows long-term satisfaction with little deterioration. Nonunion, particularly around the triquetrum, continues to be a problem, but it may be that this bone should be excised along with the scaphoid, resulting in a three-part fusion only. Alternatively, a simple capitolunate fusion may be satisfactory.

Project description:PURPOSE: Partial wrist arthrodesis is a commonly performed procedure for the treatment of posttraumatic wrist arthritis because of its ability to provide pain relief without sacrificing complete wrist motion. The purpose of this study was to evaluate the redistribution of force after four-corner fusion and scaphoid excision, and to correlate the findings with the reported clinical outcomes. METHODS: Fifteen cadaveric wrists were used to study the biomechanics of the four-corner fusion. Pressure-sensitive film (super-low-pressure-indicating film-Pressurex, Sensor Products Inc, Madison, NJ) was inserted into the radiocarpal joint. Using the MTS 858 Mini Bionix (MTS System, Eden Prairie, MN), 50-kg loads (220 N) were applied to the wrists before and after simulated four-corner fusion and scaphoid excision. Statistically, we compared the pressure in the normal (intact) wrists versus four-corner fusion and scaphoid excision. The pressure measurements across the scaphoid fossa, lunate fossa, and triangular fibrocartilage complex (TFCC) were compared. RESULTS: There is a statistical significant difference between scaphoid, lunate, and TFCC mean total force when pre and post-fusion were compared (p = 0.0001). Our study revealed a statistical significant decrease in the mean scaphoid total force after scaphoid excision and four-corner fusion (p = 0.0001). We also found a subsequent increase in mean total force after scaphoid excision and four-corner fusion for the lunate fossa that did not reach statistical significance (p = 0.08), and no difference in load across the TFCC area (p = 0.995). CONCLUSIONS: Our findings suggest that load is preferentially transferred to the radiolunate joint after scaphoid excision with four-corner fusion.

Project description:Ankle arthrodesis is still considered the gold standard in the treatment of advanced painful ankle osteoarthritis. More than 3 decades ago, it was performed under arthroscopy; thereafter, many authors have reported excellent results and a low complication rate. Despite the significant improvements in surgical techniques, nonunion remains a problematic and relatively frequent event. This is one of the reasons the research is constantly active in this field. Ten years ago, a fibular resection during ankle arthrodesis was, for the first time, described in the literature as a means to correct malalignment in varus cases. Nowadays, we perform a similar technique during all arthroscopic ankle arthrodeses, regardless of the kind of preoperative deformity (varus, valgus, or normal alignment). In this article, we describe the arthroscopic technique to perform a fibular intra-articular resection during arthroscopic ankle arthrodesis, joining the benefits of arthroscopic minimal invasiveness to the full joint contact gained after such a fibular osteotomy. In our opinion, this would be the only way through which full contact between the talar and tibial surfaces may be achieved.

Project description:A retrograde nail with posterior-to-anterior (PA) locking into os calcis, talus and tibia was used to correct deformity and achieve fusion after failed fusion. A variety of methods have been published to achieve union of the ankle and subtalar joint in a failed fusion situation. We have studied a retrograde locking nail technique through a 2.5-cm incision in the non-weightbearing part of the sole of the foot. Remaining cartilage in the ankle joint, where necessary, was percutaneously removed through an anterior approach and the locking nail was inserted after reaming of os calcis, talus and tibia. Locking screw insertion was in the sagittal plane (p.a. direction), in talus os calcis and tibial diaphysis using a nail mounted jig. Ten patients were entered in the study (age 27-60 years). The initial aetiology for attempted fusion was post-traumatic in nine cases and rheumatic in one case. There were 25 previous operations in the cohort not leading to fusion. An additional temporary external fixator was used in four cases to reach and maintain the optimum position for the procedure. The intervention time was 30-75 min. Dynamisation of the nail was performed after four months under local anaesthesia. The mean duration of follow-up was 4 years (3-5.5 years). Radiologically and clinically, fusion was achieved in 16 weeks (range, 12-20 weeks). There was no loosening of the implant or implant failure. A leg length discrepancy was avoided using this technique. There was one complication with varus malunion in a heavy smoker which united after corrective osteotomy, revision nailing and bone grafting. Patient satisfaction was measured on a scale (not visual analogue) of 0 (not satisfied) to 10 (completely satisfied); overall satisfaction averaged 9.5 points (range, 6-10 points). The postoperative ankle-hindfoot score of the American Orthopedic Foot and Ankle Society averaged 73.5 points (range, 61-81 points). Retrograde locked nailing with locking in the sagittal plane is a reliable minimally invasive procedure to achieve fusion of the ankle and the subtalar joint after failed fusion.

Project description:An anatomically based posterolateral corner (PLC) reconstruction has emerged as a viable and clinically effective surgical technique for midsubstance ligamentous injuries in both the acute and chronic settings. There are several surgical techniques for PLC reconstruction; however, the classic anatomic reconstruction technique (LaPrade technique) is now considered the gold standard and was originally described using an Achilles tendon allograft. In this article, we describe a modified LaPrade autograft technique, in which the same tunnel position, graft passage, and fixation are used to reproduce the 3 primary stabilizers of the PLC. Instead of allografts, hamstring autografts are used while tunnel diameters and fixation devices are adapted to them. With the use of autograft tendons, difficulties related to graft length or asymmetry are encountered. We consider this technique a good alternative for an anatomically based PLC reconstruction, especially given the lower availability and higher cost of allograft tissues in several countries.

Project description:Introduction This article compares opioid use patterns following four-corner arthrodesis (FCA) and proximal row carpectomy (PRC) and identifies risk factors and complications associated with prolonged opioid consumption. Materials and Methods The PearlDiver Research Program was used to identify patients undergoing primary FCA (Current Procedural Terminology [CPT] codes 25820, 25825) or PRC (CPT 25215) from 2007 to 2017. Patient demographics, comorbidities, perioperative opioid use, and postoperative complications were assessed. Opioids were identified through generic drug codes while complications were defined by International Classification of Diseases, Ninth and Tenth Revisions, Clinical Modification codes. Multivariable logistic regressions were performed with p < 0.05 considered statistically significant. Results A total of 888 patients underwent FCA and 835 underwent PRC. Three months postoperatively, more FCA patients (18.0%) continued to use opioids than PRC patients (14.7%) ( p = 0.033). Preoperative opioid use was the strongest risk factor for prolonged opioid use for both FCA (odds ratio [OR]: 4.91; p < 0.001) and PRC (OR: 6.33; p < 0.001). Prolonged opioid use was associated with an increased risk of implant complications (OR: 4.96; p < 0.001) and conversion to total wrist arthrodesis (OR: 3.55; p < 0.001) following FCA. Conclusion Prolonged postoperative opioid use is more frequent in patients undergoing FCA than PRC. Understanding the prevalence, risk factors, and complications associated with prolonged postoperative opioid use after these procedures may help physicians counsel patients and implement opioid minimization strategies preoperatively.
