OBJECTIVE The objective of our study was to retrospectively evaluate the association between abnormalities of the lesser tuberosity and subscapularis tendon lesions. MATERIALS AND METHODS Cortical irregularities and cysts of the lesser tuberosity were evaluated on radiographs and MR images in 70 patients: 31 with normal subscapularis tendons and 39 with subscapularis tendon tears. These imagi...

BACKGROUND Anteromedialization of the tibial tuberosity has been shown to decrease mean total contact pressures of the lateral trochlea and to shift contact pressures to the medial trochlea. HYPOTHESIS Modifying the anteromedialization osteotomy to a straight anteriorization osteotomy of the tibial tuberosity can decrease trochlear contact pressures without a resultant medial shift of forces ...

BACKGROUND Fractures of the humeral greater tuberosity (GT) are a frequent injury progressively treated with arthroscopic suture anchor repair. Yet, no biomechanical study has been performed comparing fixation strength of arthroscopic single- (SR) vs. double row (DR) fixation. METHODS Standardized fractures of the greater tuberosity were created in 12 fresh frozen proximal humeri. After rando...

Anatomic and operative textbooks and current literature do not clearly describe the Achilles tendon interface to the calcaneal tuberosity. We dissected 51 specimens to identify the detailed anatomy of the Achilles tendon insertion. Achilles tendon fascicles expanded from the anterior aspect of the distal Achilles tendon over the retrocalcaneal bursa to the anterior part of the Haglund's tuberos...

Patients with metatarsal fractures often present to primary care settings. Initial evaluation should focus on identifying any conditions that require emergent referral, such as neurovascular compromise and open fractures. The fracture should then be characterized and treatment initiated. Referral is generally indicated for intra-articular or displaced metatarsal fractures, as well as most fract...

BACKGROUND AND PURPOSE The diagnosis and treatment of isolated greater tuberosity fractures of the proximal humerus is not clear-cut. We retrospectively assessed the clinical and radiographic outcome of isolated greater tuberosity fractures. PATIENTS AND METHODS 30 patients (mean age 58 (26-85) years, 19 women) with 30 closed isolated greater tuberosity fractures were reassessed after an aver...

OBJECTIVE To compare the viability of transferring the lower and transverse trapezius to the greater tuberosity using three different techniques. METHODS Twelve shoulders from six cadavers were used. The primary outcome was to assess the suture viability of the trapezius muscle transfer to the greater tuberosity in the insertion topography of the infraspinatus, with the arm adducted during in...

This article describes a patient in whom total knee arthroplasty was performed for neuropathic joint disease secondary to diabetes mellitus after severe bone destruction eroded the tibial tuberosity. At initial examination, radiographs of the knee showed bone destruction in the medial and anterior regions of the tibia, and fine bone fragments were seen in the joint. Conservative therapy was per...

Stress lesions of the shoulder in athletic and active adolescents are most commonly associated with overhead sports. One of the most uncommon stress lesions of the shoulder in adolescents is an avulsion of the lesser tuberosity of the proximal humerus. To our knowledge, only 2 other cases of lesser tuberosity avulsions from repetitive motion have been reported, both of which were secondary to b...

We describe 24 fractures of the tuberosity of the calcaneus in 22 patients. Three were similar to the type of avulsion fracture which has been well-defined but the remainder represent a group which has been unrecognised previously. Using CT and operative findings we have defined the different patterns of fracture of the calcaneal tuberosity. Ten fractures extended into the subtalar joint, but d...
