Repair of Proximal Hamstring Tears: A Surgical Technique.

ABSTRACT: Proximal hamstring tears are among the most common sports-related injuries. These injuries often occur as strains or partial tears at the proximal muscle belly or the musculotendinous junction, with avulsion injuries of the proximal attachment occurring less frequently. Regardless of the mechanism, they produce functional impairment and negatively affect an athlete's performance. Various classifications for these injuries are reported in the literature. Early surgical treatment is recommended for patients with either a 2-tendon tear/avulsion with more than 2 cm retraction or those with complete 3-tendon tears. Surgery can be performed in the chronic phase but it is technically demanding because of scar formation and tendon retraction. This Technical Note describes a biomechanically validated surgical technique for repair of the proximal hamstring tears.

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.

Project description:PurposeTo develop a clinically meaningful proximal hamstring tear classification system and to present outcome data for defined subtypes.MethodsRetrospective review was undertaken of patients diagnosed with proximal hamstring tears at a single institution from 2012 to 2019. Images were reviewed by an orthopedic surgeon and musculoskeletal radiologist. Tears were classified as Type 1: partial with subtypes (1A, 1 cm or mild complete tear; 1B, 1-2 cm or full tear with <2 cm retraction), Type 2: complete single-tendon tears with subtypes (2c conjoint tendon only; 2s semimembranosus tendon only); or Type 3: complete tears with >2 cm retraction. Demographics, patient-reported outcome measures including Hip Outcome Score, Activities of Daily Living Subscore (HOS-ADL) and patient satisfaction were evaluated. A poor outcome was defined as HOS-ADL < 80%, and the patient acceptable symptom state (PASS) was defined as HOS-ADL 89.7%.ResultsAt a mean follow-up of 38.6 (range: 12-94) months for 114 patients, distributions were as follows: 18.4% Type 1A, 19.2% Type 1B, 7.8% Type 2c, 3.5% Type 2s, and 50.9% Type 3. Intra-observer and inter-observer reliability had a mean Kappa of 0.985 (95% CI: .956, 1.01) and .905 (95% CI: .895 .915). 66 patients underwent surgery, with 68.97% of them being Type 3. The mean HOS-ADL and PASS rate were higher for operatively treated patients (95%, 93.4%) than for nonoperatively treated patients (81.86%, 44.7%). There were significantly more patients satisfied in the surgery group in both Type 1 and Type 3 tears (P = .046 and P = .049). Body mass index was a significant predictor of a poor outcome in Type 3 tears (P = .039). History of corticosteroid or PRP injection, smoking, and diabetes were not significant predictors of a poor outcome.ConclusionWe present an MRI-based classification system for proximal hamstring injuries with both excellent intra-observer and inter-observer reliability. Outcome measures were improved in patients who underwent surgery.Level of evidenceIV, cohort study: diagnostic case series.
