Project description:Background and purposeThumb carpometacarpal (TCMC) osteoarthritis is a common condition that causes pain and functional limitations. We compared the outcomes of 2 surgical procedures for TCMC osteoarthritis, the Epping resection-suspension arthroplasty and the double-mobility TCMC prosthesis, and focused on pain relief, functional outcomes, and patient quality of life.Patients and methodsOver a 7-year period a randomized controlled trial including 183 cases of TCMC osteoarthritis was conducted comparing a double mobility TCMC prosthesis (Moovis, Stryker, Kalamazoo, MI, USA) with the Epping resection-suspension arthroplasty. Pre- and postoperative examinations included the range of motion (ROM), SFMcGill score, visual analogue scale (VAS), the disabilities of the arm, shoulder and hand questionnaire (DASH), and the hospital anxiety and depression scale (HADS).ResultsAt the 6-week postoperative follow-up, significant differences were found in VAS: Epping median 4.0 (interquartile range [IQR] 2.0-5.0) vs. TCMC prosthesis 2.0 (IQR 0.25-4.0), p = 0.03, effect size (area under the curve [AUC]) 0.64 (95% confidence interval [CI] 0.55-0.73), in DASH score: Epping 61 (IQR 43-75) vs. TCMC prosthesis 45 (IQR 29-57), p < 0.001, AUC 0.69 (CI 0.61- 0.78), and in radial abduction: Epping 55 (IQR 50-60) vs. TCMC prosthesis 62 (IQR 60-70), p = 0.001, AUC 0.70 (CI 0.61-0.79). No significant group differences were found at the 6- and 12-months follow-up. During the follow-up period, 3 of 82 prostheses had to be revised but there was no revision in the Epping group.ConclusionThe double mobility TCMC prosthesis had superior outcomes compared with the Epping procedure at 6 weeks; however, there were no significant differences in outcomes at 6 months and 1 year postoperatively. The implant survival rate of 96% after 12 months was acceptable.
Project description:Tendon transfer options to reconstruct a massive irreparable posterior-superior rotator cuff tear include latissimus dorsi, teres major, or lower trapezius transfer. We previously described the lower trapezius transfer using a 2-incision approach, which includes a medial incision to harvest the lower trapezius and lateral transacromial incision to expose the rotator cuff and then perform the transfer through a deep tunnel connecting these 2 sites. In this report, we describe an arthroscopic-assisted technique of lower trapezius transfer augmented with an Achilles tendon allograft to reconstruct an irreparable posterior-superior rotator cuff tear.
Project description:Patellar tendon disruption is one of the most dreaded complications after total knee arthroplasty (TKA) impacting joint function and implant longevity. Management of this condition remains controversial, and no one treatment has provided consistent clinical success. Here we propose a modified technique from the standard Achilles allograft procedure to reconstruct a ruptured patellar tendon after TKA. A fresh-frozen Achilles tendon allograft with attached calcaneal bone graft was used. Our technique offers the advantage of a more stable graft fixation by relying on both quadriceps tendon and transosseous patellar fixation and bone-to-bone allograft fixation to the tibial tuberosity. The patient regained full extension and discontinued walking aids postoperatively. Careful attention to graft preparation, tensioning, stable graft fixation, and postoperative rehabilitation led to encouraging results in this complex problem.
Project description:Conflicts of the capitolunate, causing midcarpal pain from friction can be isolated (e.g., avascular necrosis of the proximal pole of the capitate [AVNC], palmar midcarpal instability [PMCI]) or form part of a framework of more complex osteoarthritis phenomena (e.g., scaphoid pseudarthrosis [SNAC], and lesions of the scapholunate capsuloligamentous complex [SLAC]). We group in the term "conflict" all of the causes (with intact cartilage or not) causing midcarpal pain by friction. Treatment by capitolunar arthrodesis can be effective, but inevitably stiffening. In other more specific cases (i.e., AVNC), replacement of the proximal pole of the capitate with a synthetic implant or a tendon has shown variable results. In this work, we propose a management of these conflicts with a conservative arthroscopic technique, including capitolunate tendon interposition. We describe arthroscopic midcarpal tendon interposition (AMTI) for capitolunate conflicts. This technique prevents stiffness due to arthrodesis, but good experience in wrist arthroscopy is required to perform this operation.
Project description:Trapeziometacarpal osteoarthritis is a common entity, often bilateral and predominantly affecting postmenopausal women. In the case of failure of conservative treatment, surgery is a good option. The aim of this study was to compare three surgical procedures. 63 patients (74 thumbs) with osteoarthritis of the trapezio-metacarpal joint were surgically treated; 54 patients were seen for follow-up, 7 had died and 2 were lost to follow-up. The patients were stratified according to treatment; resection arthroplasty (the joint surface's of the metacarpal and the trapezium are resected) (18 thumbs), trapeziectomy with tendon interposition (17 thumbs) or trapezio-metacarpal arthrodesis (28 thumbs). Baseline characteristics were comparable in the three groups for mean age at operation, Eaton classification, left right distribution and dominant hands operated. The average follow-up was 13 years for the resection group, 8 years for the trapeziectomy group and 9 years for the arthrodesis group. No statistically significant difference between the three groups was found for the visual analogue pain and satisfaction scale, pain frequency nor DASH score. Patients in the trapeziectomy group had significantly less pain compared to the arthrodesis group (p=0.025). Statistically, radial abduction was significantly better after trapeziectomy compared to resection arthroplasty (p<0.01) or arthrodesis (p=0.01). There was no difference among the three groups in grip and tip pinch strength nor in pain on palpation. None of the patients in the trapeziectomy group needed a re-operation, one patient in the resection arthroplasty group had a re-operation, and 22 patients in the arthrodesis group had one or more re-operations for hardware removal or because of a complication. This study shows that the resection arthroplasty has equally good long term results compared to trapeziectomy combined with tendon interposition or arthrodesis. Resection arthroplasty is performed through a single incision and is technically simple. In our clinic resection arthroplasty is therefore the preferred technique for the treatment of osteoarthritis of the trapeziometacarpal joint.
Project description:Stiffness and pain secondary to end-stage dysfunctional osteoarthritis of the elbow can pose a therapeutic dilemma. Although total elbow arthroplasty is successful in older patients with low functional demand, alternatives to joint replacement must be found in the younger, more active individual. Interposition arthroplasty provides a salvage option for young, high-demand patients who hope to minimize functional restrictions of the affected extremity. The procedure traditionally involves release of both collateral ligaments and the joint capsule, resulting in a higher risk for postoperative instability and complications. The present unilateral technique demonstrates an approach maintaining the integrity of the medial or lateral collateral ligament while still allowing secure graft fixation. Stability can usually be preserved without ligament reconstruction or hinged external fixation if the elbow was stable before surgery.
Project description:Primary or revision irreparable rotator cuff tears remain a challenge. Clear algorithms do not exist. Several joint-preserving options are available, but no technique has been definitely proven to be better than another. Although superior capsule reconstruction has been shown to be effective in restoring motion, lower trapezius transfer can provide strong external rotation and abduction moment. The aim of the present article was to describe an easy and reliable technique to combine both options in 1 surgery, aiming to maximize the functional outcome by getting motion and strength back.
Project description:PurposeThe objective was to measure the intraoperative load tolerance of the thumb carpometacarpal (CMC) joint after trapeziectomy, tendon suspension, and interposition.MethodsIn this single-center prospective study, preoperative pinch grip, thumb mobility, and hypermobility of the thumb CMC joint were determined by 2 hand surgeons. Patients completed the brief Michigan Hand Outcomes Questionnaire. During surgery and upon removal of the trapezium, the surgeon subjectively rated the degree of thumb CMC load tolerance as "stable," "medium stable," or "unstable." A measurement system with an integrated force sensor was used to measure intraoperative thumb CMC load tolerance. The thumb ray was displaced manually by 10 mm toward the scaphoid, and the counteracting force was measured over the entire displacement. The objective load tolerance was determined as the maximal measured force after trapezium resection, tendon suspension, and interposition. Analysis of variance was used to test for the differences in load tolerance between the surgical steps. Spearman's coefficient was used to find correlations between load tolerance and clinical or patient-reported variables.ResultsTwenty-nine patients with a mean age of 70 years (SD, 8.1 years) were available for analysis. The measured intraoperative load tolerance after trapeziectomy was 15.5 N (SD, 5.4 N) and significantly increased to 18.7 N (SD, 5.5 N) after suspension. Load tolerance only slightly increased after tendon interposition, increasing the force to 20.3 N (SD, 6.7 N). Neither the surgeon's subjective stability rating nor the clinical or patient-reported variables correlated with the measured load tolerance after trapeziectomy.ConclusionsOur results show that tendon suspension leads to the highest increase in thumb CMC load tolerance during resection-suspension-interposition arthroplasty.Clinical relevanceTendon suspension appears to be the most important step in stabilizing the metacarpal base after trapeziectomy, whereas tendon interposition does not seem to have a relevant additional effect regarding load tolerance, at least immediately after surgery.
Project description:BackgroundTrapezius palsy results from injury to the spinal accessory nerve. The condition presents with loss of shoulder abduction, pain, and winging of the scapula. Surgical treatment may improve functional outcomes and quality of life.PurposeThe purpose of this study was to report and evaluate the clinical outcomes following surgical management of trapezius palsy.Study designSystematic review.MethodsThe electronic databases EMBASE, MEDLINE, and PubMed were searched for studies and relevant data were abstracted. Only studies reporting on outcomes after the surgical treatments of trapezius palsy were included.ResultsA total of 10 studies including 192 patients were included in this review. All surgical interventions resulted in improved function and pain reduction. Patients reported high satisfaction (90-92%) following nerve reconstruction or the Eden-Lange procedure, in comparison to neurolysis. The most common procedure reported was the Eden-Lange muscle transfer (32% reported cases) demonstrating the highest patient satisfaction rates with low complication rate of 7.7%.ConclusionPatients failing conservative treatment report good outcomes following surgical treatment of trapezius palsy. All reported surgical procedures demonstrate reduction in pain the best results from the Eden-Lange muscle transfer. Further high-quality comparative studies are required to make definitive conclusions regarding the comparative efficacy of each surgical procedure.
