ABSTRACT
Hand and wrist injuries in martial arts are typically a reflection of the combat nature of this discipline. In striking sports, the axial load mechanism of injury is common and causes fractures and dislocations; in grappling sports, sprain injuries and degenerative changes predominate. There is clear evidence to support that hand protection reduces the risk of hand injury. Traditional training in martial arts on proper technique and target selection in striking sports reduces the risk of hand injury, and is an important component of hand and wrist injury prevention.

Chondroblastoma is a rare, benign primary bone tumor that usually occurs at the epiphysis of long bones. The authors present an example of the diagnosis and successful treatment of this neoplasm in an exceedingly rare location in the distal phalanx. Clinical and radiographic outcomes after 68 months of follow-up are presented. A 15-year-old, right hand-dominant, boy developed painful swelling of the right ring finger. Radiographs revealed a radiolucent lesion of the distal phalanx with expansile remodeling of the bone. An excisional biopsy was performed with curettage and bone grafting of the lesion. The diagnosis of chondroblastoma was made based on pathologic evaluation of the biopsy specimen. Sixty-six months after surgical treatment, the patient was free of recurrence and metastatic disease with excellent clinical and functional outcomes. To the authors' knowledge, this represents only the second reported case of chondroblastoma of the distal phalanx. The diagnosis of chondroblastoma in this rare location was made by pathologic review of the resection specimen. It is imperative to confirm the diagnosis of any resected bone specimen even when the concern for an aggressive or malignant lesion is low. A tumor presenting in an unusual location may require a change in treatment or surveillance.

We report a case of periosteal osteosarcoma, an uncommon juxtacortical osteosarcoma variant, in the metacarpal of a 5-year-old girl treated with wide excision and chemotherapy with no recurrence at 25 months.

OBJECTIVE: To determine whether the post-harvest magnetic resonance (MR) imaging appearance of flexor carpi radialis (FCR) tendons, harvested during ligamentous reconstruction tendon interposition (LRTI) of the thumb carpometacarpal (CMC) joint arthroplasty, is consistent with tendon regeneration. DESIGN: Operative reports and patient medical records for all patients undergoing LRTI arthroplasty between 1995 and 2003 at our institution were reviewed. MR images of the patients' forearms and wrists were obtained and interpreted by two musculoskeletal radiologists. Using the flexor carpi ulnaris (FCU) tendon as an internal standard, the extent of FCR tendon regeneration was expressed as a percentage by dividing the volume of regenerated FCR tendon by the volume of the FCU tendon. PATIENTS: Fourteen patients who had the full thickness of the FCR tendon harvested and who were available for MR imaging were identified and included in the study. RESULTS AND CONCLUSIONS: At least partial regeneration of the FCR tendon occurred in 11 of the 14 patients (79%). Of these, 2 patients (14%), demonstrated complete, or nearly complete regeneration. Partial regeneration of the FCR tendon was seen in 9 of the 14 patients (64%). In 3 patients (21%), there was no appreciable regeneration of the FCR tendon. Among patients who underwent full-thickness harvest of the FCR tendon for LRTI arthroplasty of the first CMC joint, the follow-up MR imaging appearance of the flexor carpi radialis tendon was consistent with tendon regeneration in 79% of those examined.

Proximal fibular stress fracture is an uncommon injury in athletes but has been frequently reported in the military population. Although the true incidence is unknown and its pathophysiology is not completely understood, proximal fibular stress fracture is believed to be a rare injury and awareness of it will help clinicians make the proper diagnosis and provide appropriate treatment.
