ABSTRACT
Bony avulsion injuries of the triangular fibrocartilage complex (TFCC) caused by penetrating wrist trauma are rare, and there is limited literature available regarding their treatment. This case report describes a 54-year-old male who sustained a penetrating injury to his right wrist, resulting in "double lesion" of TFCC injury, which are ulnar avulsion (Palmer 1B) and radial avulsion (Palmer 1D) lesion with a sigmoid notch fracture. The patient underwent an arthroscopic examination and a novel arthroscopic technique for fixation and repair of the TFCC injury. The procedure involved debridement, repair of the dorsal radioulnar ligament bony avulsion, and fixation of the foveal bony avulsion of the TFCC. The patient's wrist was immobilized postoperatively, followed by gradual rehabilitation. At the final follow-up of six months, the patient demonstrated improved range of motion and functional outcomes. This case report highlights the successful use of arthroscopic techniques for the treatment of complex TFCC avulsion injuries resulting from penetrating wrist trauma.
ABSTRACT
The incidence of non-fatal gunshot wounds has significantly increased in the past decade. The current guidelines lack clarity in treatment of bullet wounds to the hand and wrist. An 18-year-old male presented to the emergency department with a gunshot wound to the hand/wrist resulting in an open fracture. The entrance wound was clean without visible bone. No neurovascular damage was reported. The wound was irrigated with saline, and a sterile dressing and splint was applied in the emergency department. The patient was discharged the same day with oral antibiotics and an appointment with an orthopedic hand specialist. Three days after the injury, the patient was taken to surgery to treat a fracture of the radius and lunate. No internal fixation was required. The fracture and bullet fragments were removed, and the patient was discharged on the same day. The patient recovered to a full range of motion and no infection was acquired throughout treatment and healing. The current guidelines for the treatment and management of nonfatal gunshot wounds to the hand and wrist are inconsistent resulting in unnecessary admittance to the hospital. Our paper provides a template for future cases allowing for outpatient treatment.
ABSTRACT
BACKGROUND: Penetrating upper extremity injury is a common encountered cause of significant loss of labor force and it is generally caused by sharp items. This article presents five rare cases of penetrating hand and forearm injury caused by blunt-edged items in conjunction with a detailed discussion of the mechanism and management of the injury. METHODS: Five patients with a mean age of 37.6 were treated for upper extremity trauma caused by "blunt-edged items" such as corrugated iron fence, garden wires, iron stick or iron safety fence between 2009 to 2014. All patients were operated under general anesthesia after performing detailed physical examination and x-ray imaging. RESULTS: The explorative surgery of the affected limbs revealed no nervous or vascular injury. In two patients, partial tear of the muscles bellies of intrinsic hand muscles (opponens pollicis and adductor pollicis); in two patients, partial extensor digitorum communis tendon laceration and in the remaining patient, partial tear of the third annular pulley were the only encountered injuries. The physical examinations performed in the last visit of each patient revealed, complete healing of the affected limb without any functional, vascular or sensorial deficiency in a mean follow-up period of 19.2 months. CONCLUSIONS: Despite their initial horrible appearance, injuries caused by "blunt-edged items" are quite harmless to the affected limb because they follow weak anatomic spaces of the extremity and cause minimal tissue damage leaving all vascular and nervous structures intact.
