Dry Endoscopic-Assisted Mini-Open Approach With Neuromonitoring for Chronic Hamstring Avulsions and Ischial Tunnel Syndrome.

ABSTRACT: Chronic hamstring origin avulsions and ischial tunnel syndrome are common causes of posterior hip pain. Although physical therapy has shown benefits in some cases, recent evidence has reported better outcomes with surgical treatment in appropriately selected patients. The full-open approach has been the classic procedure to address this problem. However, the complications related to extensive tissue exposure and the proximity of the incision to the perianal zone have led to the description of full-endoscopic techniques. Achieving an accurate hamstring repair could be technically demanding with a full-endoscopic procedure. Accurate reattachment is crucial in hamstring repair because of the functional demand of the muscles crossing of 2 major joints (hip and knee). This surgical note describes a mixed technique including a mini-open approach, neuromonitoring, and dry endoscopic-assisted repair of the hamstring origin as an alternative for treating patients with chronic hamstring avulsions and ischial tunnel syndrome that remain symptomatic despite nonoperative treatment.

Project description:BackgroundCarpal tunnel syndrome is the most common upper-extremity nerve compression syndrome. Over 500,000 carpal tunnel release (CTR) procedures are performed in the U.S. yearly. We estimated the cost-effectiveness of endoscopic CTR (ECTR) versus open CTR (OCTR) using data from published meta-analyses comparing outcomes for ECTR and OCTR.MethodsWe developed a Markov model to examine the cost-effectiveness of OCTR versus ECTR for patients undergoing unilateral CTR in an office setting under local anesthesia and in an operating-room (OR) setting under monitored anesthesia care. The main outcomes were costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). We modeled societal (modeled with a 50-year-old patient) and Medicare payer (modeled with a 65-year-old patient) perspectives, adopting a lifetime time horizon. We performed deterministic and probabilistic sensitivity analyses (PSAs).ResultsECTR resulted in 0.00141 additional QALY compared with OCTR. From a societal perspective, assuming 8.21 fewer days of work missed after ECTR than after OCTR, ECTR cost less across all procedure settings. The results are sensitive to the number of days of work missed following surgery. From a payer perspective, ECTR in the OR (ECTROR) cost $1,872 more than OCTR in the office (OCTRoffice), for an ICER of approximately $1,332,000/QALY. The ECTROR cost $654 more than the OCTROR, for an ICER of $464,000/QALY. The ECTRoffice cost $107 more than the OCTRoffice, for an ICER of $76,000/QALY. From a payer perspective, for a willingness-to-pay threshold of $100,000/QALY, OCTRoffice was preferred over ECTROR in 77% of the PSA iterations. From a societal perspective, ECTROR was preferred over OCTRoffice in 61% of the PSA iterations.ConclusionsFrom a societal perspective, ECTR is associated with lower costs as a result of an earlier return to work and leads to higher QALYs. Additional research on return to work is needed to confirm these findings on the basis of contemporary return-to-work practices. From a payer perspective, ECTR is more expensive and is cost-effective only if performed in an office setting under local anesthesia.Level of evidenceEconomic and Decision Analysis Level I.

Project description:ImportanceCarpal tunnel release (CTR) technique may influence the likelihood of revision surgery. Prior studies of revision CTR following endoscopic CTR (ECTR) compared with open CTR (OCTR) have been limited by sample size and duration of follow-up.ObjectiveTo estimate the incidence of revision CTR following ECTR compared with OCTR in a national cohort.Design, setting, and participantsThis retrospective cohort study used data from the US Veterans Health Administration. Participants included all adults (age ≥18 years) undergoing at least 1 outpatient CTR from October 1, 1999, to May 20, 2021. Data were analyzed from May 21, 2021, to November 27, 2023.ExposureIndex CTR technique.Main outcomes and measuresThe primary outcome was time to revision CTR, defined as repeat ipsilateral CTR during the study period. Secondary outcomes were indications for revision, findings during revision, and additional procedures performed during revision.ResultsAmong 134 851 wrists from 103 455 patients (92 510 [89.4%] male; median [IQR] age, 62 [53-70] years) undergoing at least 1 CTR, 1809 wrists underwent at least 1 revision at a median (IQR) of 2.5 (1.0-3.8) years. In competing-risks analysis, the cumulative incidence of revision was 1.06% (95% CI, 0.99%-1.12%) at 5 years and 1.59% (95% CI, 1.51%-1.67%) at 10 years. ECTR was associated with increased hazard of revision CTR compared with OCTR (adjusted hazard ratio [aHR], 1.56; 95% CI, 1.34-1.81; P < .001). The risk difference for revision CTR associated with ECTR compared with OCTR was 0.57% (95% CI, 0.31%-0.84%) at 5 years (number needed to harm, 176) and 0.72% (95% CI, 0.36%-1.07%) at 10 years (number needed to harm, 139). Regardless of index CTR technique, the most common indication for revision was symptom recurrence (1062 wrists [58.7%]). A reconstituted transverse carpal ligament (TCL) was more common after ECTR compared with OCTR, whereas scarring of the overlying tissues and of the median nerve itself were more common following OCTR. Incomplete transverse-carpal-ligament release was observed in 251 of the wrists undergoing revision CTR (13.94%) and was more common among revisions following ECTR (odds ratio, 1.62; 95% CI, 1.11-2.37; P = .01).Conclusions and relevanceIn this cohort study of revision CTR in the Veterans Health Administration, ECTR was associated with increased risk of revision compared with OCTR, but the absolute risk was low regardless of technique. Intraoperative findings at revision varied significantly according to index CTR technique.

Project description:Ischial avulsion fractures classically occur in the pediatric population and are relatively uncommon. These injuries are treated conservatively; however, in cases where there is greater than 2 cm of displacement, surgical intervention is recommended. In some cases, displaced fractures are either misdiagnosed or proper treatment is neglected, and patients who transition into adulthood are left with chronic nonunions that can become a source of pain and disability. Here we present a surgical technique for a chronic ischial avulsion fracture nonunion that is excised, and the hamstring tendons are then primarily repaired to the ischium using suture anchors. Technique Video Video 1 This is a video for the surgical intervention for a patient with a chronic right sided ischial avulsion fracture. The patient is placed in the prone position with all bony prominences padded. After a standard sterile prep and drape of the right lower extremity, an 8 to 10 cm incision is made in the gluteal crease, overlying the right-sided ischium. Electrocautery is used to reveal the underlying gluteal fascia. The gluteal fascia is incised using dissecting scissors. A Schnitt is used to open the interval inferior to the gluteus maximus muscle, and a large retractor is placed. A sciatic neurolysis is performed. The chronic avulsion fracture is revealed using electrocautery. A combination of electrocautery and a cobb elevator is used to free the bony fragment. After removal, the eburnated surface of the ischium is revealed. A combination of curettes and osteotomes are used to create a bleeding bone bed on the native ischium. Next, two 2.8 mm Q-fix (Smith and Nephew, Andover, MA) double-loaded all-suture anchors are placed into the native ischium. From each anchor, 1 suture limb from 1 pair is passed through the hamstring tendon in a locking fashion while the other is left free. From the other suture pair from the same anchor, one limb is passed in a modified Mason-Allen technique, and the other limb is left free. This is repeated for the other anchor. Using the free limbs of the anchors, the tendon is delivered to the ischium. The corresponding suture limbs are tied, and the free ends are cut with a knife. After copious irrigation a multilayer closure is performed. Dermabond is placed on the skin and a dry sterile dressing. After surgery the patient is made flat foot weightbearing in a hip orthosis and is started on chemical anticoagulation. At the first postoperative visit the wound is evaluated, and an X-ray film is obtained.
