Arthroscopic release of the pectoralis minor tendon from the coracoid for pectoralis minor syndrome.

Purpose: The term "pectoralis minor syndrome" refers to this constellation of symptoms that can occur when the pectoralis minor (Pm) is shortened and contracted. Release of the tendon of the Pm from the coracoid has been reported to provide substantial clinical improvement to patients presenting with pectoralis minor syndrome. The purpose of this study was (1) to describe the technique for endoscopic release of pectoralis minor tendon at the subdeltoid space, (2) to classify the pectoralis minor syndrome according to its severity and (3) and to report the short-term outcomes of this procedure in a consecutive series of patients diagnosed with pectoralis minor syndrome.

Ultrasound of the elbow with emphasis on the sonoanatomy of the distal biceps tendon and its importance for the surgical treatment of tendon lesions.

Degenerative or traumatic ruptures of the distal biceps tendon are less common than proximal lesions. Distal lesions lead to a significant loss of function with usually considerable discomfort for patients. Therefore, precise diagnostics using operator-dependent high-resolution musculoskeletal ultrasound with illustration of the extent of the affected tendon lesion are important for optimizing patient management.

Most coronoid fractures and fracture-dislocations with no radial head involvement can be treated nonsurgically with elbow immobilization.

Hypothesis: Conservative treatment of isolated coronoid fractures and fracture-dislocations focused on soft-tissue healing can provide good clinical results in the majority of patients. Our aims were (1) to evaluate the outcome of a conservative treatment protocol designed for isolated coronoid fractures with or without associated elbow dislocations (ICFs) and (2) to characterize the fractures with a dedicated image analysis protocol.

Methods: Of 38 consecutive patients sustaining acute ICFs, 28 were treated nonsurgically after meeting specific inclusion criteria, prospectively followed up, and clinically evaluated at least 1 year after sustaining their injuries.

Tissue on the Transferred Coracoid Graft After Latarjet Procedure: Histological and Morphological Findings.

Background: Anterior shoulder instability is a debilitating condition that can require stabilization via a Latarjet procedure.

Purpose: The aim of this study was to characterize the histological composition of the articular-sided surface of the coracoid bone graft after Latarjet procedure. Specific features of cells isolated from the coracoid and graft tissues were assessed.

Arthroscopic Double-Layer Lasso Loop Technique to Repair Delaminated Rotator Cuff Tears.

Purpose: To evaluate the arthroscopic double-layer lasso loop repair technique for delaminated posterosuperior rotator cuff tears.

Methods: Forty-one patients underwent arthroscopic rotator cuff repair of a delaminated posterosuperior rotator cuff tear by the double-layer lasso loop technique. Their preoperative and postoperative clinical and functional scores were compared to evaluate surgical outcomes.

Arthroscopic and Endoscopic Technique for Subcoracoid Synovial Chondromatosis of the Shoulder Through a Medial Transpectoral Portal.

Synovial chondromatosis of the shoulder is a rare disorder characterized by metaplastic synovial proliferation, causing multiple loose bodies usually localized intra-articularly. Surgical treatment with open techniques through a deltopectoral approach has been commonly used. The evolution of arthroscopy has allowed a complete joint assessment and the extraction of intra-articular loose bodies with less morbidity than open techniques.

Arthroscopic double bone block augmentation is a salvage procedure for anterior and posterior shoulder instability secondary to glenoid bone loss.

Purpose: The aim of this study was to describe a one-step arthroscopic anterior and posterior bone block augmentation technique for bidirectional shoulder instability and to present preliminary results.

Methods: Seven consecutive patients who underwent a concomitant anterior and posterior bone block procedure between 2007 and 2015 were retrospectively reviewed. Clinical scores, return to sport rate, and complications were assessed.

Does the Arthroscopic Latarjet Procedure Effectively Correct "Off-Track" Hill-Sachs Lesions?

Background: The glenoid track concept describes the dynamic interaction of bipolar bone loss in anterior glenohumeral instability. Initial studies have successfully demonstrated this concept's application in clinical populations. In clinical practice, the Latarjet procedure is commonly the preferred treatment in addressing "off-track" Hill-Sachs lesions.

Three-dimensional volume measurement of coracoid graft osteolysis after arthroscopic Latarjet procedure.

Background And Hypothesis: The Latarjet procedure has been shown to be a reliable method to prevent recurrent anterior shoulder instability. Coracoid bone graft osteolysis is a potential catastrophic complication and can lead to recurrent instability. The purpose of our study is to present a novel quantitative method to measure the amount of coracoid bone osteolysis using 3-dimensional (3D) computed tomography (CT) scan imaging.

Total Arthroplasty of the Metatarsophalangeal Joint of the Hallux.

Background: The current gold standard in the treatment of severe hallux rigidus is arthrodesis of the first metatarsophalangeal (MTP-I) joint. We present the results of a new 3-component MTP-I prosthesis. We determined (1) the intraoperative and perioperative complications; (2) survivorship of prosthesis components and rate of secondary surgeries for any reason; (3) prosthetic component stability and radiographic alignment; (4) the degree of pain relief; and (5) the midterm functional outcomes including radiographic range of motion (ROM).

Implant failure after biodegradable screw fixation in osteochondritis dissecans of the knee in skeletally immature patients.

Purpose: The primary purpose of this study was to retrospectively assess the incidence of bioabsorbable screw failure in skeletally immature patients treated for osteochondritis dissecans (OCD) of the knee. The second purpose was to assess implant degradation, focusing on differential breakdown of the intraosseous and extraosseous parts of the screw on magnetic resonance imaging (MRI).

Methods: In this retrospective study, 24 patients (30 knees) with MRI-confirmed OCD were treated with a total of 61 biodegradable screws and followed up for a minimum of 2 years or until the onset of new symptoms.

Unexplained proximal tibiofibular joint pain after high tibial osteotomy.

Problems of the proximal tibiofibular joint (pTFj) after high tibial osteotomy (HTO) are rare. With this case report, we strive to highlight the importance of investigating the pTFj in patients with unexplained knee pain after HTO. A 44 year old male patient presented with diffuse pain on his left knee 3 years after medial opening wedge HTO due to medial compartment overloading in a varus knee.
