Clinical Efficacy Analysis of Circumferential Upper Arm Liposuction with Double Incision: A Study of 496 Cases.

BACKGROUND: In cases where the upper arm exhibits an irregular cylindrical appearance with subcutaneous fat concentrated primarily in the posterior lateral aspect, traditional localized fat suction techniques may lead to uneven or disharmonious results when addressing this concern. Many practitioners have turned to circumferential fat suction methods using multi-incision approaches to ensure effective results and fat removal. However, these methods often involve numerous incisions and complex procedures, necessitating the development of new, more efficient surgical techniques. METHODS: We collected and screened patients who underwent upper arm circumferential liposuction with a double incision technique at our hospital from October 2020 to February 2023. A total of 496 cases were included in our retrospective analysis, in which we examined factors such as the length of surgery, arm circumference before and after surgery, subcutaneous tissue thickness before and after surgery, fat suction volume, postoperative satisfaction, and postoperative complications of the patients. RESULTS: The average length of surgery was 71.7 min. 458 cases (92.3%) showed significant improvement, 23 cases (4.6%) reported satisfaction, and 10 cases (2.0%) were essentially satisfied. Additionally, 339 cases (68.3%) experienced an improvement in skin laxity. Four cases (0.8%) developed localized hard nodules with slight tenderness in the early postoperative period, which resolved without special treatment after observation and follow-up for 1-3 months. Three cases (0.6%) reported localized pain or numbness, and they were given oral medication. Their symptoms disappeared after 1-3 months of observation and follow-up. Three cases (0.6%) had localized pain or numbness, and their symptoms disappeared. All of these cases improved and resolved after one month of taking mecobalamin tablets. There were also three cases (0.6%) with mild pigmentation of the incision and two cases (0.4%) with mild limitation of unilateral upper arm abduction movement. However, upper arm activities were not affected after three months to one year of follow-up. No serious complications were reported, resulting in an overall satisfaction rate of 99.0%. CONCLUSION: The double incision upper arm liposuction is safe, effective, time-saving, with high satisfaction and fewer complications, and is worthy of clinical popularization and application.

Outcomes of enhanced recovery protocols and tranexamic acid on double-incision versus periareolar gender-affirming mastectomy: A retrospective study of postoperative outcomes.

INTRODUCTION: The effects of enhanced recovery protocols and use of tranexamic acid (TXA) to reduce postoperative complications after periareolar and double-incision (DIM) gender-affirming mastectomies have not been previously described. We sought to evaluate the efficacy of our ERP including use of liposomal bupivacaine [Exparel] in these cases, assess the efficacy of TXA in reducing postoperative complications, and compare need for revisionary surgery between periareolar and DI mastectomy techniques. MATERIALS AND METHODS: A retrospective review from November 2017 to June 2022 was performed. Data were collected on patient demographics, operative data, and postoperative outcomes including complications and revisions. Morphine milligram equivalent was used to assess opioid use after surgery. RESULTS: Overall, 260 patients were included: 240 (92.3%) patients in the DI and 20 (7.7%) patients in the periareolar group. Thirty-five (7.3%) breasts in the DIM group and five (12.5%) breasts in the periareolar cohort developed complications (p = 0.220). Significantly more breasts in the periareolar cohort developed hematomas (12.5% vs. 2.9%, p = 0.011). Sixteen (3.3%) breasts in the DIM group developed seromas. Significantly more breasts in the periareolar group required revisionary surgery (15.0% vs. 5.2%, p = 0.025). Patients who received intraoperative liposomal bupivacaine [Exparel] had fewer opioids intraoperatively (p = 0.019) and at discharge (p < 0.001). Use of TXA did not affect rates of complications including hematoma or seroma. CONCLUSIONS: Overall, complication rates for periareolar and DIM are similar. However, the periareolar technique results in a significantly higher rate of hematomas and revisionary surgery. Use of intraoperative liposomal bupivacaine [Exparel] resulted in significantly lower opioid use. Lastly, use of topical TXA did not lower the risk of postoperative hematoma or seroma.

Distal biceps tendon rupture: a comprehensive overview.

Distal biceps tendon (DBT) is a relatively rare injury mainly occurring in middle-aged men while in eccentric biceps muscle contraction. Clinical appearance with proximal avulsion of the muscle and specific clinical tests are most of the time sufficient for diagnosing DBT, but if needed ultrasonography and MRI, most often in FABS view, can be used to ensure diagnosis of DBT and partial DBT. Surgical anatomical reinsertion has shown to be a successful method of treatment, although conservative treatment can be initiated in older patients. Two different approaches are described in literature: single- and double-incision techniques with different fixation methods proving to have similarly good results. Major complications of surgical intervention are posterior interosseous nerve palsy and symptomatic heterotropic ossification. Overall outcome of surgical intervention has shown high subjective satisfaction with slight weakness in flexion and supination but mostly without loss in range of motion.

Double-incision mastectomy after reduction mammaplasty for persistent gender dysphoria: a case report.

Most patients undergo just one type of gender-affirming top surgery, but some will have a double-incision mastectomy after reduction mammaplasty. We describe a 46-year-old transgender man who requested a flatter chest after undergoing reduction mammoplasty the previous year. We also provide three considerations to guide surgical decision-making in this situation.

A comparative study of single and double incision for L4/5 and L5/S1 double-level percutaneous interlaminar lumbar discectomy.

Objective: This study aims to investigate the clinical outcome of single and double incision for double-level percutaneous interlaminar lumbar discectomy. Methods: A retrospective analysis was performed involving patients with L4/5 and L5/S1 double-level lumbar disc herniation who received percutaneous interlaminar lumbar discectomy (PEID) in our hospital from January 2017 to December 2020. These enrolled patients were divided into single- and double-incision groups, with 25 patients in each group. We compared the incision length, operation time, fluoroscopy times, and length of hospital stay between the two groups. Meanwhile, the postoperative visual analogue scale (VAS), Oswestry Disability Index (ODI), Japanese Orthopedic Association score (JOA), and modified MacNab standard were used to evaluate the outcomes of the patients within the two groups. Results: It showed that the single-incision group performed better than double-incision group in incision length, operation time, and fluoroscopy times (P < 0.001). The VAS score, JOA score, and ODI index in the two groups were significantly decreased at the time points of postsurgery, 1 month after surgery, and the last follow-up (P < 0.01), but there was no statistical significance between the two groups involving above parameters (P > 0.05). At the last follow-up, the excellent and good rates of MacNab efficacy in the two groups were 92% and 88%, respectively, but no significant difference was observed between the two groups (P > 0.05). Conclusion: Both the single- and double-incision approaches are effective and safe for managing L4/5 and L5/S1 double-level LDH. Single-incision PEID for treating L4/5 and L5/S1 double-segment lumbar disc herniation has advantages of less trauma, fewer intraoperative fluoroscopy times, and shorter operation time, as compared to double-incision PEID. However, the operation of double-segment LDH through a single laminar incision is difficult, the learning curve is steep, and professional skill is highly required. Importantly, the surgical indications should be strictly grasped.

Treatment of symptomatic hip dysplasia by posterolateral small incision assisted Bernese periacetabular osteotomy.

BACKGROUND: For periacetabular osteotomy, traditional approaches usually have a long learning curve. We aimed to evaluate the postoperative results and complications of periacetabular osteotomy under a new double-incision approach. METHODS: The records of 58 consecutive patients (65 hips) who underwent periacetabular osteotomy using the new approach were retrospectively reviewed and evaluated. There were 52 women and 6 men with a mean age of 28.1 years at the time of surgery. RESULTS: The average follow-up period was 35.2 months, during which no patients were converted to total hip arthroplasty. Complications included 6 hips (9.2%) with nerve dysesthesias and 1 hip (1.5%) with delayed wound healing. The mean operative time and intraoperative blood loss were 88.6 min and 402.8 ml, respectively. The mean modified Harris hip score had improved from 72.2 points preoperatively to 91.3 points at the last follow-up. Fifty-five patients (62 hips, 95.4%) were satisfied to their outcomes, and good preoperative functional score was associated with a satisfactory outcome. Furthermore, the average lateral center-edge angle, anterior center-edge angle and acetabular index angle were corrected well after surgery. CONCLUSION: Periacetabular osteotomy using modified Smith-Petersen or Bikini approach with posterolateral assisted small incision can be performed safely and with satisfactory results. In addition, this technique shortens the learning curve, and reduces the operating complexity, especially for beginner.

Interrupted Incision Fasciotomy for Acute Compartment Syndrome After Extracorporeal Membrane Oxygenation: Surgical Technique with a Report of Two Cases.

BACKGROUND: After extracorporeal membrane oxygenation (ECMO), acute compartment syndrome (ACS) can develop because of limb ischemia or reperfusion. The standard treatment for ACS is emergency fasciotomy. We introduced an interrupted incision technique instead of a long double-incision to reduce blood loss and subsequent hypovolemia in ECMO patients. CASE PRESENTATION: Two patients were treated venoarterial ECMO with heparinization by inserting cannulas into their right femoral vessels: Case #1 after emergency pulmonary thrombectomy for massive pulmonary thrombi and Case #2 after percutaneous coronary intervention for ST-elevation myocardial infarction with ventricular fibrillation. Some of the '5 P' signs of ACS were detected on their right legs. We treated them with the interrupted incision fasciotomy: four or five skin incisions of 2-3 cm each on lateral side; one 6-7 cm proximal skin incision with one or two separate short distal skin incisions of 1-1.5 cm each on the posteromedial side. The subcutaneous layer was also incised through these interrupted incisions; interrupted multiple "soft tissue tunnels" can be formed above muscle layer between the incisions. Once the fascia was exposed, the connected fasciotomy was performed with the knife blade facing subcutaneous layer, rather than muscle. The two patients' foot pulse, skin color, and muscle tone were immediately restored, and delayed primary wound closures were possible. Both patients were satisfied with their limb salvage and could walk with a little help using an orthosis or a cane. CONCLUSIONS: We recommend the interrupted incision fasciotomy as an attractive and effective technique for ACS, particularly after ECMO.

Distal biceps tendon repair: cost analysis of single- versus double-incision techniques in an ambulatory surgery center.

Background: The purpose of this study was to compare the cost differences for single- versus double-incision distal biceps repair at an ambulatory surgery center (ASC) given that similar clinical outcomes have been reported between these methods. Methods: A retrospective review of financial and medical records was completed for patients who underwent distal biceps tendon repair over a three-year period at a single private orthopedic practice. Variables analyzed include the cost to the ASC of operative time and the cost of differential surgical supplies, specifically implants and disposable supplies. Results: A total of 10 surgeons performed 104 repairs. Nine surgeons performed repairs through a single incision with use of cortical button or suture anchor fixation, and one surgeon performed transosseous suture fixation through a double-incision approach. The median tourniquet time and procedure length were 31 (interquartile range [IQR] 27-40) and 44 (IQR 39-54) minutes for single-incision repairs and 68 minutes (IQR 61-75) and 110 minutes (IQR 103-113) for double-incision repairs which were significantly different across groups (P < .001, P < .001). The total surgical cost (operative time, implants, and disposables) for single-incision repairs was a median of $758 (IQR 732-803) compared with $606 (IQR 567-629) for double-incision repairs (P < .001). However, the procedure cost with implants (not including disposables) was not significantly different for single- (median [Mdn] = $500 [IQR 475-552]) and double-incision repairs (Mdn $552 [IQR 514-564]) (P = .14) although the procedure cost with disposables (not including implant costs) favored single-incision repairs (Mdn = $478 [IQR 452-523]) over double-incision repairs (Mdn = $606 [IQR 567-629]) (P < .001). Conclusion: In a single surgery center, single-incision distal biceps repairs utilizing an implant were performed more expeditiously than double-incision repairs with a transosseous technique but incurred greater surgical costs. Differences in surgical time cost between the two approaches could be consequential for ASCs and other stakeholders.

Acute distal biceps tendon rupture: retrospective analysis of two different approaches and fixation techniques.

PURPOSE: The aim of our study is to compare the modified double incision (DI) with bone tunnel reinsertion with the single-incision (SI) double tension slide technique in terms of clinical and functional outcomes and complication rates. METHODS: A retrospective comparative analysis was performed on 65 patients treated for total distal biceps tendon rupture. The surgical technique adopted for each patient was based on the preference of two experienced elbow surgeons. The DASH and MAYO questionnaires, functional outcome and ROM were recorded in all subjects. RESULTS: Of 65 patients, we collected data of a cohort of 54 distal biceps tendon ruptures that satisfied inclusion criteria. Twenty-five were treated by modified DI and 29 SI techniques. The recovery of the complete ROM in terms of flexion/extension and prono-supination occurred in the 79.6% of the patients, without statistical significant difference between the adopted technique. We reported a complication rate of 12% and 20.7% for DI and SI techniques, respectively, without statistical correlation (P = 0.84). The average DASH score was similar for DI and SI techniques without significant differences (P = 0,848). The Mayo score results were excellent in the majority of the patients. No significant difference in MAYO results was reported comparing the surgical techniques (P = 1). CONCLUSION: Both techniques provide a reliable and strong repair with an optimal recovery of ROM returning to preinjury activity with substantially overlapping timelines.

Acute distal biceps repair using double incision technique: results of a standardized home rehabilitation protocol / Reparación aguda del bíceps distal mediante técnica de doble incisión: resultados de un protocolo estandarizado de rehabilitación domiciliaria

Abstract: Introduction: Distal biceps tear can lead to loss in flexion and supination strength. Early repair in active patients is recommended. Postoperative rehabilitation varies according to surgeon experience and surgical technique used. The aim of this study is to present the results of a series of patients using a standardized home rehabilitation protocol after a distal biceps repair with double incision technique. Material and methods: This is a retrospective case study. We registered 21 patients with distal biceps tear, surgically treated using a double incision technique and transosseous suture fixation, followed by a home-based exercise program. Patients were evaluated using MEPS score, DASH questionnaire, and the subjective/objective scoring system of Andrews and Carson. Radiographic assessment was done for heterotopic bone formation. Results: Mean MEPS was 95 (range 70 to 100), DASH score 0.4 (range 0 to 4.2), and subjective and objective Andrews and Carson score was 99 (range 90 to 100). Two patients developed heterotopic ossifications. Range of motion was recovered in every patient. All patients went back to their previous surgical activities. Conclusions: Patients treated with double incision repair for distal biceps tear can undergo a home rehabilitation protocol, expecting normal range of motion and strength recover.

Triple-Endobutton and clavicular hook: A propensity score matching analysis.

We retrospectively analyzed the clinical data of 635 patients with acute acromioclavicular dislocation, who underwent surgery in our hospital between May 2014 and June 2020. Patients were divided into group A (clavicular hook plate) and group B (Triple-Endobutton plates via double-incision). The propensity score analysis using one to one match was performed for comparisons. We obtained 292 matched patients' data. The matched preoperative clinical characteristics were a balance between the two groups. All clinical parameters showed insignificant differences (P > 0.05). Compared with group A, group B has longer operative time (P < 0.001) and more blood loss (P < 0.001); however, the mean incision length (P < 0.001) and length of hospitalization (P < 0.001) were shorter in group B than in the group A. The mean VAS in group B were significantly lower than in group A at each time point (P < 0.001), and the UCLA shoulder score was higher in the group B. The CMS scores were also higher in group B than in group A, including before removal and 12 weeks after removal (P < 0.001). The clinical efficacy of the double-incision Triple-Endobutton plate is better than the clavicular hook plate technology, and achieves anatomical reduction by reconstructing coracoclavicular ligament.

Single Medial vs 2-Incision Approach for Double Hindfoot Arthrodesis: Is There a Difference in Joint Preparation?

BACKGROUND: Double hindfoot arthrodesis is a reliable treatment option in lower extremity deformity and arthritis. Single (medial) and 2-incision techniques have been described. The purpose of this study was to evaluate the extent of cartilage debrided in each approach and to evaluate the competency of the deltoid ligament. METHODS: Eight matched pairs of cadaveric specimens were acquired. One limb from each pair was randomly assigned to the single medial incision and the other to the 2-incision technique. Stress radiographs were obtained prior to dissection to evaluate for valgus tibiotalar tilt. The talonavicular and subtalar articular surfaces were denuded of cartilage and the joints disarticulated. The percentage of cartilage debrided was determined using ImageJ software. Postoperative tibiotalar tilt was measured with a technique and threshold previously described by our group. The intraclass correlation coefficient was calculated to determine inter- and intraobserver reliability. RESULTS: The single medial incision demonstrated significantly less cartilage denuded than the 2-incision technique at the talar head (61.1% ± 20.4% vs 88.1% ± 6.1%, P < .001), and the posterior facets of the talus (53.5% ± 7.6% vs 73.6% ± 7.0%, P < .001) and calcaneus (55.3% ± 16.5% vs 81.0% ± 7.4%, P = .001). Overall, 75% of specimens that underwent a single medial incision approach demonstrated increased valgus tibiotalar tilt postdissection, whereas none that underwent the 2-incision technique developed increased tibiotalar tilt (P < .01). The average tibiotalar tilt among these specimens was 4.6 ± 1.3 degrees (range 2.5-5.7 degrees). For all measurements, the intraclass correlation coefficient was greater than 0.8. CONCLUSION: The posterior facet of the subtalar joint and talar head are at risk of subtotal debridement, as well as increased tibiotalar tilt with the single medial incision technique. Adequate debridement may require greater soft tissue dissection, possibly at the expense of medial ankle stability. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Double-Incision approach with suspension of the orbicularis oculi muscle and relieving of tension for upper eyelid rejuvenation in Asian women.

BACKGROUND: In Asian women, upper eyelid skin laxity, lateral hooding, and upper eyelid and brow asymmetry in the aging upper eyelid are prominently and frequently seen. It is difficult to completely resolve these problems with the classical single-incision method. In this study, we investigate the utility of a double-incision approach to address aging-related changes of the upper eyelid. METHODS: From September 2017 to March 2019, 51 patients underwent this procedure. Through a sub-brow incision, the skin and subcutaneous tissue were excised and the orbicularis oculi muscle (OOM) flap and muscular-cutaneous flap were separated. The OOM flap was lifted and fixed to the periosteum through the sub-brow fat pad and covered by the upper muscular-cutaneous flap. Through an eyelid crease incision, the supratarsal upper eyelid skin, muscle, and orbital fat were excised, excessive tension was alleviated, and double-fold eyelids were adjusted and reshaped if needed. The results were evaluated by asking the surgeon and patient involved to allocate a categorical (poor, fair, good, very good, excellent) scores and comparisons between pre- and postoperative brow position. RESULTS: The average follow-up period was 12 months. Most patients were satisfied with the results, barring two cases each of vomiting and transient numbness over the forehead region and three revisions. The mean surgeon and patient categorical scores associated with satisfaction with the overall outcome at 6 months were 4.2 ±â€¯0.6 (range 3.0-5.0) and 4.0 ±â€¯0.7 (range 2.0-5.0), respectively. The brow position was stable during follow-up period. CONCLUSION: A double-incision approach is a safe, effective, durable, and esthetic way for treating patients presenting with upper eyelid aging.

Minimal Damage to the Supinator Muscle After the Double-Incision Technique for Distal Biceps Tendon Repair.

BACKGROUND: The effect of the double-incision technique on the supinator muscle is unclear. PURPOSE: The aim of this study was to quantify fatty atrophy of the supinator muscle and map the area of muscle damage. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 19 male patients (median age, 43 years) who underwent distal biceps tendon repair were included in the analysis. Patients with a minimum of 12 months of follow-up were included. The following variables were analyzed: range of motion; shortened version of Disabilities of the Arm, Shoulder and Hand (QuickDASH) score; Summary Outcome Determination (SOD) score; and isokinetic peak force and endurance in supination. Quantitative analysis and mapping of fatty infiltration of the supinator muscle were based on the calculation of proton density fat fraction on magnetic resonance imaging scans of both elbows using the IDEAL (Iterative Decomposition of Echoes of Asymmetrical Length) sequence. RESULTS: At an average follow-up of 24 months (range, 12-64 months), the median SOD score was 9.0 (95% CI, 7.8-9.4), and the mean QuickDASH score was 6.7 (95% CI, 0.0-14.1). A difference of 17% in peak torque was measured between repaired and nonrepaired elbows (repaired elbow: 9.7 N·m; nonrepaired elbow: 11.7 N·m; P = .11). Endurance was better in the repaired elbow than the nonrepaired elbow (8.4% vs 14.9% work fatigue, respectively; P = .02). The average fat fraction of the supinator muscle was 19% (95% CI, 16%-21%) in repaired elbows and 14% (95% CI, 13%-16%) in contralateral elbows (P = .04). The increase in fat fraction was located in a limited area between the radius and ulna at the level of the bicipital tuberosity. CONCLUSION: The assessment of the supinator muscle showed a limited increase in fat fraction between the radius and ulna at the level of the bicipital tuberosity. No significant effect on supination strength was highlighted.

Single- versus double-incision technique for the treatment of distal biceps tendon rupture.

AIMS: The aim of this systematic review and meta-analysis is to evaluate differences in functional outcomes and complications between single- (SI) and double-incision (DI) techniques for the treatment of distal biceps tendon rupture. METHODS: A comprehensive search on PubMed, MEDLINE, Scopus, and Cochrane Central databases was conducted to identify studies reporting comparative results of the SI versus the DI approach. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used for search strategy. Of 606 titles, 13 studies met the inclusion criteria; methodological quality was assessed with the Newcastle-Ottawa scale. Random- and fixed-effects models were used to find differences in outcomes between the two surgical approaches. The range of motion (ROM) and the Disabilities of the Arm, Shoulder and Hand (DASH) scores, as well as neurological and non-neurological complications, were assessed. RESULTS: A total of 2,622 patients were identified. No significant differences in DASH score were detected between the techniques. The SI approach showed significantly greater ROM in flexion (standardized mean difference (SMD) -0.508; 95% confidence interval (CI) -0.904 to -0.112) and pronation (SMD -0.325, 95% CI -0.637 to -0.012). The DI technique was associated with significantly less risk of lateral antebrachial cutaneous nerve damage (odds ratio (OR) 4.239, 95% CI 2.171 to 8.278), but no differences were found for other nerves evaluated. The SI group showed significantly fewer events of heterotopic ossification (OR 0.430, 95% CI 0.226 to 0.816) and a lower reoperation rate (OR 0.503, 95% CI 0.317 to 0.798). CONCLUSION: No significant differences in functional scores can be expected between the SI and DI approaches after distal biceps tendon repair. The SI approach showed greater flexion and pronation ROM and a lower risk of heterotopic ossification and reoperation. The DI approach was favourable in terms of lower risk of neurological complications. Cite this article: Bone Joint J 2020;102-B(12):1608-1617.

Distal Biceps Tendon Repair Using a Modified Double-Incision Technique: Patient-Reported Outcomes With 10-Year Follow-up.

BACKGROUND: In the setting of complete distal biceps tendon rupture, surgical repair has become the standard of care to restore optimal elbow function, but the optimal approach and method of tendon fixation are still subjects of debate and have remained controversial for more than half a century. PURPOSE: To evaluate patient-reported long-term outcomes after distal biceps tendon repair using a modified double-incision technique. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: We reviewed primary distal biceps tendon repairs after isolated tendon rupture using the modified muscle-splitting double-incision approach and transosseous suture fixation technique described by Morrey et al (1985), which had been performed at our level 1 trauma center between January 2000 and December 2013. Outcome measures included the subjective elbow value (SEV), the Oxford Elbow Score (OES) with its 3 domains (function, pain, and social-psychological), a self-performed hook test, and the 3-level version of the EuroQoL 5-dimensional instrument (EQ-5D-3L) as a measure of health status. Levels of overall satisfaction were determined by asking whether the patient would consent to the operation again. In addition, patients were asked to report any complications. RESULTS: A total of 30 patients met the inclusion criteria, and 25 patients were available for the survey. Mean age at the time of rupture was 47 years. All patients were male. Mean follow-up was 120 months (range, 57-207 months). The follow-up rate was 83.34%. The following outcome results were obtained: SEV, 88.16% ± 25.18%; OES, 43.80 ± 10.56 out of 48 points; OES Pain, 92.50% ± 23.03%; OES Function, 92.25% ± 22.19%; OES Social-Psychological, 89% ± 23.68%; EQ-5D-3L, 0.93 ± 0.21. All patients described a negative hook test. Patient-reported complications included painless limitation in forearm rotation in 8% of patients (n = 2); reduced flexion and forearm rotation strength with and without pain in 8% (n = 2) and 4% (n = 1), respectively; synostosis after 1 year requiring revision surgery in 4% (n = 1); and transient wrist drop in 4% (n = 1). The overall complication rate was 28% (7/25), and 96% (n = 24) would consent to the operation again. CONCLUSION: Despite the cited approach-related morbidity, we report an excellent patient-reported long-term outcome for the double-incision distal biceps repair technique.

Supination torque following single- versus double-incision repair of acute distal biceps tendon ruptures.

BACKGROUND: Compared with single-incision (SI) distal biceps repair, double-incision (DI) repair has been described as permitting a more anatomic repair. We hypothesized that DI repair would result in greater terminal supination torque compared with SI repair for acute distal biceps ruptures. METHODS: Patients were included if they sustained an isolated, acute distal biceps rupture repaired between January 2012 and December 2017. Isometric forearm supination torque in 4 positions was measured using a validated uniaxial torque-testing device. Testing took place at least 12 months from surgery. The primary outcome was supination torque in the 60° supinated position. Secondary outcomes included supination torque in other forearm positions and functional outcome scores. RESULTS: The study included 37 patients: 15 underwent repair with the DI technique and 22 with the SI technique. The mean age was 47.3 years, the median follow-up time was 28.1 months, and demographic data were similar between cohorts. Mean supination torque, relative to the unaffected side, was 61% (95% confidence interval, 45%-77%) for DI repair vs. 80% (95% confidence interval, 69%-92%) for SI repair in the 60° supinated position (P = .036). In a multivariable linear regression model controlling for arm dominance, age, follow-up time, and workers' compensation status; SI repair was associated with greater mean supination torque than DI repair by 20% (P = .015). CONCLUSIONS: Contrary to our hypothesis, we found a 20% mean improvement in terminal supination torque for acute distal biceps ruptures repaired with the SI technique compared with the DI technique. This finding may have clinical significance for the more discerning, high-demand patient.

Efficacy of the "Salento technique", a modified two-incision approach in distal biceps brachii tendon repair. Surgical description and outcomes analysis.

INTRODUCTION: The biceps brachii lesion needs to be treated surgically. A modified two incisions technique is proposed and reviewed. Material and Methods: All patients were treated with the same technique. The outcomes were measured with the Quick-DASH Score (QDS), and the Mayo Elbow Performance Score (MEPS). Postoperative complications and distal biceps tendon strength were registered also. RESULTS: At one year from the trauma, the QDS and the MEPS were excellent in all patients. 72.97% fully recovered and returned to work after 6 months from the trauma. DISCUSSION: This technique, thanks to its preservation of anatomical structures, provides great outcomes.

Posterior Interosseous Nerve Proximity to Cortical Button Implant for Distal Biceps Repair With Single and 2-Incision Approaches.

PURPOSE: Fixation with a cortical button is the biomechanically strongest surgical approach for distal biceps repair, and utilization of the 2-incision approach may provide a more anatomical repair and improved terminal supination strength. The risk of injury to the posterior interosseous nerve (PIN) associated with this approach requires further investigation. METHODS: A distal biceps repair with a cortical button was performed on 10 cadavers, 5 utilizing the single-incision approach and 5 utilizing the 2-incision approach. Contrast was injected into the radial nerve and computed tomography scans were obtained. The distance between the drilled cortical perforation and the PIN was measured. RESULTS: The mean distance from the cortical perforation to the PIN was not significantly different between approaches (9.4 mm and 8.8 mm). A PIN entrapment was seen in 0 out of 5 for the single-incision approach and 1 out of 5 for the 2-incision approach. CONCLUSIONS: Distal biceps repair with cortical button fixation places the PIN at risk of injury regardless of the approach used. Methods of fixation that require bicortical drilling should be especially avoided when using the 2-incision approach. CLINICAL RELEVANCE: Distal biceps repair utilizing bicortical drilling for fixation through a 2-incision approach poses high risk of injury to the PIN and should be avoided.
