Outcomes following adolescent athlete proximal hamstring apophyseal avulsion bone fragment excision and direct tendon-ischial tuberosity reattachment.

Apophyseal proximal hamstring bone avulsion is uncommon, occurring in adolescents following sudden forceful contraction of the musculotendinous unit. It can be severely disabling, preventing return to sport. This study assessed outcome following avulsed bone excision and direct hamstring tendon-ischial tuberosity reattachment using bone anchors.

Distal avulsion of reconstituted hamstring tendons.

Purpose: Hamstring tendon autograft (semitendinosus and gracilis) is the most commonly used graft in anterior cruciate ligament (ACL) reconstruction. Distal hamstring tendons avulsion is a rare condition, and this paper describes a previously unreported injury, local management of this rare injury pattern, and the existing literature regarding treatment options.

Methods: Two cases are presented of distal hamstring avulsion from the tibia of reconstituted tendons, together with additional 12 cases of distal hamstrings tendon avulsion.

Validation of the Sydney Hamstring Origin Rupture Evaluation (SHORE).

Aims: To validate the Sydney Hamstring Origin Rupture Evaluation (SHORE), a hamstring-specific clinical assessment tool to evaluate patient outcomes following surgical treatment.

Methods: A prospective study of 70 unilateral hamstring surgical repairs, with a mean age of 47.3 years (15 to 73).

The Natural History of Biointerference Screw Cyst and New Bone Formation in Anterior Cruciate Ligament Reconstruction: 16-Year Follow-up.

Background: A variety of fixation devices are available for anterior cruciate ligament reconstruction (ACLR). Bioabsorbable screws allow imaging postoperatively without image artefact, as with magnetic resonance imaging (MRI). There is also the perceived benefit of screw resorption and subsequent host tunnel bone ingrowth.

Medial meniscal cyst as a cause of painful erosion of the tibial plateau.

Medial cysts are rarely encountered as a cause of bone erosion. It is thought meniscal cysts are present in up to 22 % of meniscal tear operations. MRI is the gold standard for visualisation of meniscal cysts.

Bio-interference screw cyst formation in anterior cruciate ligament reconstruction--10-year follow up.

Purpose: This study used serial MRI to assess the absorption of a poly l-lactide Bioabsorbable interference screw used in the anterior cruciate ligament reconstruction with a 4-strand hamstring technique.

Methods: A consecutive series of ten patients undergoing anterior cruciate ligament reconstruction a 4-strand hamstring technique were assessed with magnetic resonance imaging (MRI) scans at 1, 2, 4, 7 and 10 years postoperatively.

Results: No resorption had occurred after 4 years in any of the patients.

Hamstring injuries: anatomy, imaging, and intervention.

Injury to the hamstring muscle complex (HMC) is extremely common in the athletic community. Anatomical and functional aspects of the HMC predispose it to injury, including the fact that the muscles cross two joints and undergo eccentric contraction during the gait cycle. Injury most commonly occurs at the muscle tendon junction but may occur anywhere between the origin and insertion.

Isolated avulsion of the vastus lateralis tendon insertion in a weightlifter: a case report.

Introduction: We report a case of isolated, unilateral avulsion of the vastus lateralis tendon from its insertion at the patella. This was diagnosed by magnetic resonance imaging, and underwent successful surgical repair.

Case Presentation: A healthy 32-year-old national level power lifter presented with an isolated avulsion of the vastus lateralis tendon.

Avulsion of the proximal hamstring origin. Surgical technique.

Background: The torn hamstring is a common athletic injury. The purpose of the present study was to review the clinical presentation of this injury, the diagnostic imaging findings, the surgical technique of reattachment, and the likely clinical outcome of surgery for the treatment of avulsion of the proximal hamstring origin.

Methods: Seventy-two consecutive reconstructions in seventy-one patients with avulsion of the proximal hamstring origin were performed at a single center.

The natural history of a bioabsorbable interference screw used for anterior cruciate ligament reconstruction with a 4-strand hamstring technique.

Purpose: The purpose of this study was to assess radiologically the rate of absorption of the Arthrex poly L-lactide bioabsorbable interference screw (Arthrex, Naples, FL) used in anterior cruciate ligament reconstruction with a 4-strand hamstring technique.

Type Of Study: Case series.

Methods: Eight sequential patients undergoing anterior cruciate ligament reconstruction with a 4-strand hamstring technique were assessed with magnetic resonance imaging (MRI) scans at 1, 2, and 4 years postoperatively.
