Finger metacarpal fractures and dislocations in children

Metacarpal fractures in the finger rays are common injuries in children's hands. Fractures of the finger metacarpals account for 10% to 39% of all hand fractures in children,especially in the 13- to 16-year age group. Most of these fractures can be treated success-fully nonoperatively, although a subset requires more aggressive treatment. Results following appropriate care of these fractures are generally good, although complications can occur. This article reviews fractures and dislocations involving the finger metacarpals in children, provides standard treatment algorithms, and highlights potential pit-falls in their management.

Functional outcomes and mortality vary among different types of hip fractures: a function of patient characteristics

A review of prospectively collected data was done to compare functional outcomes and mortality among patients with different hip fracture types. Five hundred thirty-seven elderly patients who sustained a hip fracture were followed up prospectively. Orthopaedists blinded to treatment and outcome radiographically classified the fractures as either: (1) nondisplaced or impacted femoral neck; (2) displaced femoral neck; (3) stable intertrochanteric; or (4) unstable intertrochanteric fracture. Functional independence measure scores were calculated for preinjury function and at 2- and 6- month follow-ups. Comorbidities, operative details, postoperative complications, and deaths were recorded. Six-month mortality was lowest for patients with nondisplaced femoral neck fractures (5.7%) and highest for patients with displaced femoral neck fractures (15.8%), but multivariate analysis only identified preinjury function as an independent predictor of mortality. All preinjury and followup functional independence measure scores were greatest for patients with nondisplaced femoral neck fractures and least for patients with unstable intertrochanteric fractures. However, multivariate analysis identified only patient age and preinjury functional independence measure scores as independent predictors of functional outcome. These data show differences in mortality and functional outcomes among fracture types that can be attributed to differences in functional status before injury.

Remodeling of phalangeal neck fracture malunions in children: case report

We report a case of a malunion of a proximal phalanx neck fracture in a 5-year-old boy that remodeled nearly completely, resulting in excellent proximal interphalangeal joint motion and function.

Implanted neuroprostheses for restoration of hand function in tetraplegic patients

Restoration of hand function through functional electrical stimulation allows tetraplegic patients to use existing abilities to control paralyzed muscles. In patients with C5 or C6 spinal cord injuries, implanted upper extremity neuroprostheses use functional electrical stimulation technology to power hand and arm muscles. A variety of devices, often using contralateral shoulder motion, sends signals via a small external controller and transmitting coil to an implanted stimulator. The stimulator powers designated upper extremity muscles via implanted electrodes. The surgical procedure is minimally invasive and easily reversed. Palmar and lateral grasp, among other functions, can be reliably restored, leading to significant improvements in functional capacity. High user satisfaction, low complication rates, and recent advances in technology and control systems contribute to the success of this technology in the treatment of devastating spinal cord injuries.

Wrist joint ganglion presenting as a painless mass in the palm: report of 2 cases

Ganglions occur commonly in the wrist and arise from the radiocarpal and intercarpal joints. Although ganglions present commonly as masses on the dorsal or volar surface of the wrist, ganglions from wrist joints appear rarely at other locations in the hand. We report 2 cases of ganglions arising from wrist joints that presented as painless masses in the center of the palm without signs or symptoms of median or ulnar nerve compression. Surgical treatment required extensile exposure to trace the proximal stalks to their joints of origin. Knowledge of the possibility that a painless mass in the palm could be a ganglion arising from a joint in the wrist allows proper presurgical planning and informed consent.

Failed surgical management of partial thickness rotator cuff tears

Some authors have recommended that rotator cuff tears <50% of tendon thickness be debrided and those involving >50% of the tendon be treated with miniopen repair. We hypothesize that if indications for selecting between simple debridement and tendon repair were appropriate, then both groups should have comparable outcomes. Thirty-nine patients with partial rotator cuff tears met inclusion criteria and were available for retrospective analysis. Twenty-six percent of patients who underwent debridement and 12.5% of patients who had mini-open repair had unsatisfactory results according to Neer's criteria.

Outcomes of elderly patients with nondisplaced femoral neck fractures

Seventy patients with nondisplaced femoral neck fractures treated by cannulated screw fixation were followed up prospectively for 6 months. Preinjury Functional Independence Measure scores and comorbidities were recorded as were operative time, type of anesthesia, estimated blood loss, transfusions, and postoperative complications. Functional Independence Measure scores were reassessed at 3 and 6 months. The mean age of the patients was 78 years. The 6-month mortality was 5.7%. The mean overall Functional Independence Measure scores at 3 and 6 months were 86% and 89% of the initial score respectively. Locomotion Functional Independence Measure scores at 3 and 6 months were 73% and 89% of the initial score, respectively. Multiple regression analysis found patient age and initial overall Functional Independence Measure score to be independent predictors of overall, locomotion, and transfer Functional Independence Measure scores at 3 months. At 6 months, only initial Functional Independence Measure score predicted ultimate Functional Independence Measure scores. This suggests that patient age may affect the speed of recovery but not the ultimate functional result. Of comorbidities, only chronic obstructive pulmonary disease significantly affected functional recovery at 3 months, but not at 6 months. Operative time, estimated blood loss, type of anesthesia, and patient gender did not affect functional outcomes. Patients who sustain a nondisplaced femoral neck fracture experience predictable and lasting loss of function. Low initial functional status predicts a poorer outcome. Age and pulmonary comorbidity affect speed of recovery.

How well do you know the back of your hand? Toward evidence-based knowledge

Familiarity with the back of one's hand has long been used as a reference criterion for knowledge despite a lack of supporting evidence. The present study prospectively tests normal subjects' knowledge of dorsal hand features. Sixty surgical, medical, and allied hospital employees (30 men, 30 women) were asked 5 questions with binary answers about features on the dorsum of their dominant hands while their hands were concealed. The proportion of correct answers to each question ranged from 0.45 to 0.65, and none was significantly different from 0.50. Similarly, the mean percentage of correct answers for all subjects and all questions was 54%, which was not significantly different from 50%. Thus, the accuracy of the answers approximated random guesses. Hand specialists scored significantly higher (75%) than other occupation groups. Men and women scored equally as a whole. These data refute the use of the hand idiom as a reference criterion for knowledge.

The history of synoviorthesis in haemophilia

The history of synoviorthesis and recent studies have shown that it is a safe procedure and that the results are similar to those seen following open surgical and arthroscopic synovectomy. If the safety of this procedure is definitively proven in long-term studies it will become the procedure of choice for treatment of recurrent haemarthroses and synovitis. That is, until the time when the haematologists and geneticists eliminate the need for orthopaedic intervention in the care of persons with haemophilia.

Teaching professionalism in orthopaedic residency

Two residents, wearing white coats with their names and "Department of Orthopaedics" conspicuously embroidered on them, boarded a hospital elevator crowded with physicians, employees, and visitors. In a clearly audible voice, one resident began a story: "You should have seen the patient I saw in my clinic the other day. She was beautiful. I should send her to see Dr. W. He would love to see her!" This comment drew the undivided attention of everyone in the elevator and cast a ghastly silence over the rest of the ride. In recent years, interest has expanded regarding professionalism and its importance in medicine and surgery. Orthopaedic surgery is no exception, as the topic has recently reached prominence in our literature and policies. It is unlikely that professionalism is a universal and innate characteristic of college students entering medical school, yet it becomes a necessary value in medical practice. Somewhere in the ongoing process of medical education, the issue must be addressed.

Nerve injury in traumatic dislocation of the hip

Neurologic injury often accompanies traumatic dislocation and fracture-dislocation of the hip. A review of the literature reveals an incidence of approximately 10% in adults and 5% in children. The sciatic nerve, usually the peroneal branch, is most often injured, and this complication can be seen after all types of posterior fracture-dislocations and simple posterior dislocations. The sciatic nerve can be acutely lacerated, stretched, or compressed, or later encased in heterotopic ossification. Neurologic examination at the time of injury often is difficult but is extremely important. Once a nerve injury is discovered, prompt closed reduction must be attempted to relieve distortion of the nerve from a dislocated femoral head or displaced acetabular fracture. Considerable controversy surrounds the recommendations for additional treatment of nerve injury once the hip has been reduced. At least partial recovery of nerve function occurs in 60% to 70% of patients, with no clear correlation with injury or treatment type. Rehabilitation of patients with sciatic nerve injury must begin as early as possible and should focus on the prevention of an equinus foot deformity. Magnetic resonance neurography may become useful in the future for initial evaluation of patients with this injury.

Initial treatment of traumatic hip dislocations in the adult

The initial treatment of traumatic hip dislocations is critical to successful treatment of this injury. It generally is agreed that prompt reduction with the patient under anesthesia or sedation is required. Delay in reduction of posterior hip dislocations is associated with avascular necrosis of the hip. Occasionally the hip dislocation will be irreducible. Various methods to reduce hip dislocations have been described in the literature. The superiority of one particular technique has not been shown and the choice of reduction maneuver must be tailored to the condition of the patient. Traumatic hip dislocations often are associated with multiple injuries that may limit the options available for initial treatment of the hip dislocation. Adherence to general principles of skeletal reduction will increase the ease of reduction and decrease the risk of iatrogenic injury during reduction. Additional clinical and radiographic evaluation of the hip that was reduced often is necessary to determine whether subsequent open treatment is required.
