Background Specific findings on magnetic resonance arthrography (MRA) that indicate the need for surgery in patients with partial articular-sided supraspinatus tendon avulsion (PASTA) are not well understood. Purpose To determine which MRA findings are characteristic of patients who undergo surgery for PASTA. Material and Methods From July 2011 to February 2014, MRA findings for patients treated for PASTA were retrospectively reviewed. The patients were divided into two groups: conservative treatment and surgical repair...

During the past 2 decades, the frequency of pectoralis major muscle injuries has increased in association with the increased popularity of bench press exercises. Injury of the pectoralis major can occur at the muscle origin, muscle belly, musculotendinous junction, intratendinous region, and/or humeral insertion-with or without bone avulsion. The extent of the tendon injury ranges from partial to complete tears. Treatment may be surgical or conservative, depending on the clinical scenario and anatomic characteristics of the injury...

BACKGROUND: Reconstruction after pan-plexus root avulsions often includes gracilis free functioning muscle transfer. For elbow flexion reconstruction, the free functioning muscle transfer distal tendon is inserted into the biceps tendon or more distally (i.e., flexor digitorum profundus/flexor pollicis longus tendons) for combined elbow and finger flexion; the theoretical drawback of the latter approach is weaker elbow flexion. The authors compared elbow flexion strength with a biceps tendon versus a flexor digitorum profundus/flexor pollicis longus tendon attachment to determine which insertion point resulted in better elbow flexion...

Dislocation following total knee arthroplasty (TKA) is a rare but serious complication. Here, a 74-year-old woman with posterior dislocation of her right cruciate-retaining TKA and ipsilateral tibia diaphysis fracture was presented. She only slipped down on the ground with a quick twist of her right leg. She underwent revision semiconstrained TKA and osteosynthesis of tibial fracture with plate and screw. Her partially avulsed patellar tendon was repaired as well. She was ambulatory with a cane and satisfied with revision operation at last control...

: We examined the medium- to long-term outcome of the original reconstruction technique of the radioulnar ligament using a half-slip of the extensor carpi ulnaris tendon for chronic foveal avulsion of the triangular fibrocartilage complex. We treated 37 wrists in 36 patients with a minimum follow-up of 5 years. Of 36 patients, 12 had more than 10 years follow-up. At final follow-up, 30 patients (31 wrists) reported no pain, five patients (five wrists) reported mild occasional pain and one patient reported severe persistent pain...

BACKGROUND: Patellar tendon rupture is rare in the general population. Typically, failure occurs proximally or at the mid-substance. Distal avulsion from the tibial tubercle in adults is rare and not well described in the orthopedic literature. METHODS: We present the largest series of patients with distal patellar tendon injury with associated multi-ligamentous disruption of the knee. A series of six patients with distal patellar tendon avulsion were identified at a single institution...

In a comparative Level III study, Achtnich et al. compared suture anchor repair of acute proximal anterior cruciate ligament avulsion tears with single-bundle anterior cruciate ligament reconstruction with the quadrupled semitendinosus tendon. Short-term follow-up at a mean of 28 months showed that the between-group differences were not different. These results are encouraging but not different from other published series 25+ years ago. Only time will tell whether the long-term outcomes are identical and whether these techniques will also die a slow death...

PURPOSE: To provide the anatomical basis of brachial plexus roots for the diagnosis and treatment of brachial plexus root avulsion injury. METHODS: The morphological features of brachial plexus roots were observed and measured on 15 cervicothoracic spine of adult cadavers. The relationship of brachial plexus nerve roots and the surrounding tissues also were observed, as well as the blood supply of anterior and posterior roots of the brachial plexus. RESULTS: Origination of the nerve roots in the dorsal-ventral direction from the midline was fine-tuned at each level along the spinal cord...

C7-T1 brachial plexus palsies result in a loss of finger motion and hand function. The authors have observed that finger flexion motion can be recovered after a brachialis motor branch transfer. However, finger flexion strength after this procedure merely corresponds to Medical Research Council Grades M2-M3, lowering the grip strength and practical value of the reconstructed hand. Therefore, they used 2 donor nerves and accomplished double nerve transfers for stronger finger flexion. In a patient with a C7-T1 brachial plexus injury, they transferred the pronator teres branch to the anterior interosseous nerve and the brachialis motor branch to the flexor digitorum superficialis branch for reinnervation of full finger flexors...

Mallet fingers with an avulsion fracture of the distal phalanx or rupture of the terminal tendon of the extensor mechanism is known as a common injury, while mallet thumb is very rare. In this paper, the case of a 19-year-old woman with a sprained left thumb sustained while playing basketball is presented. Plain radiographs and computed tomography revealed an avulsion fracture involving more than half of the articular surface at the base of the distal phalanx. Closed reduction and percutaneous fixation were performed using the two extension block Kirschner wires' technique under digital block anesthesia...

The typical injury pattern of a posterior hip dislocation includes posterior wall fracture, capsular injury, and muscular strain. This report presents an example of a posterior wall acetabulum fracture-dislocation associated with complete hip abductor tendon and capsular avulsion from the femur. The patient was found to have an unstable hip despite a small posterior wall fragment due to the extensive soft tissue injury. This was repaired. The patient had improvement in function initially, but ultimately required repair of the hip abductor tendons...

INTRODUCTION: Patellar tendon rupture can occur due to multiple causes ranging from inflammatory pathologies to episodes of trauma. Extensor mechanism rupture is a rare complication of total knee arthroplasty (TKA). In most of these cases, the failure occurs as avulsion of patellar tendon from tibial tuberosity. We report a rare case with bilateral mid-substance patellar tendon rupture one month after bilateral total knee arthroplasty. CASE PRESENTATION: A 69-year-old male was operated for bilateral grade 4 osteoarthritis...

AIMS: Despite the expansion of arthroscopic surgery of the shoulder, the open deltopectoral approach is increasingly used for the fixation of fractures and arthroplasty of the shoulder. The anatomy of the terminal branches of the posterior circumflex humeral artery (PCHA) has not been described before. We undertook an investigation to correct this omission. PATIENTS AND METHODS: The vascular anatomy encountered during 100 consecutive elective deltopectoral approaches was recorded, and the common variants of the terminal branches of the PCHA are described...

PURPOSE: To compare the biomechanical properties of a knotless suture anchor with suture tape quadriceps tendon repair technique with transosseous and suture anchor repair techniques. METHODS: Twenty matched pairs of cadaveric knees underwent a quadriceps tendon avulsion followed by repair via the use of transosseous tunnels with #2 high-strength sutures, 5.5-mm biocomposite fully threaded suture anchors with #2 high-strength sutures, or 4.75-mm biocomposite knotless suture anchors with suture tape...

Extensor mechanism disruptions are relatively uncommon injuries involving injury to the quadriceps tendon, patella, or patellar tendon. Patellar tendon avulsions from the tibial tubercle in adults are rare; as such, little technical information has been written regarding surgical management of this injury in the adult. Transosseous-equivalent repairs have been described in the management of several types of tendon ruptures, including rotator cuff and distal triceps tendon ruptures, but not previously in patellar injuries...
