Results of hemiarthroplasty for complex four-part proximal humerus fractures in the elderly have been unreliable. Although patients often achieve pain relief, return of above-shoulder level function can be challenging, because tuberosity nonunion, malunion, and/or resorption is quite common. The reverse shoulder replacement has been advocated as a reliable alternative for these patients. Prelim...

Fracture of the lesser tuberosity of the humerus often occurs concomitant with posterior shoulder dislocation or proximal humeral fracture, while isolated fractures are extremely rare. We report a case in which an isolated fracture of the lesser tuberosity of the humerus occurred due to a distinctive pathogenic mechanism. A 43-year-old male had his right shoulder forced into internal-rotation (...

BACKGROUND Proximal hamstring repair for complete ruptures has become a common treatment. There is no consensus in the literature about postoperative rehabilitation protocols following proximal hamstring repair. Some protocols describe bracing to prevent hip flexion or knee extension while others describe no immobilization. There are currently no biomechanical studies evaluating proximal hamstr...

Tumors of striated muscle are sufficiently rare to make the observation of a new and characteristic case worthy of record. The rhabdomyoma which is the subject of the present discussion is of special interest because of the peculiar forms assumed by the myogenic cells and the wide variations of structure in the tumor. At the present time a detailed discussion of the literature of this neoplasm ...

Calcaneal tuberosity fractures comprise only 1 to 2% of all calcaneal fractures. Treatment of these injuries has traditionally included open reduction and internal fixation with various means including lag screws, suture anchors and K-wires. We report on a series of cases treated with excision of the tuberosity frag ment with repair of the Achilles tendon supplemented by a flexor hallucis longu...

The maxillary tuberosity can fracture during extraction of a molar tooth. If a small bony fragment is affected, the extraction of the tooth and tuberosity continues; however, a conservative approach is advised if the bony fragment is large. In a modified blind surgical technique, the tooth is removed without the fractured bone.

Hamstring strains are among the most common injuries (and reinjuries) in athletes. Studies combining electromyography with gait analysis have elucidated the timing of activity of the three muscles of the hamstring group; they function during the early-stance phase for knee support, during the late-stance phase for propulsion, and during midswing to control the momentum of the leg. Muscle injury...

BACKGROUND Patients with chronic injuries of the proximal hamstring can develop significant impairment because of weakness of the hamstring muscles, sciatic nerve compression from scar formation, or myositis ossificans. PURPOSE To describe the surgical outcomes of patients with chronic injury of the proximal hamstrings who were treated with hamstring repair and sciatic neurolysis supplemented...
