Role of emergency reconstruction of fingers by the "reposition-flap" technique. Report of eight cases

Following replantation failure, fingertip reconstruction was performed as an emergency "reposition-flap" procedure in seven patients (eight fingers). This technique was intended for amputations distal to the DIP joint in long fingers, and IP joint in the thumb. Pulp was excised on the amputated segment, and the remaining bone and nail bed were reattached to the proximal stump with Kirschner wires. Pulp was reconstructed with a local advancement and sensitive flap. Trophicity and nail regrowth as well as mobility and strength were satisfactory in five cases. MRI examination showed revascularization of the distal bone fragment in four cases. This procedure is an alternative to amputation after replantation failure when patients do not accept finger shortening. The more distal the amputation, the better is the result.     

Trendy inline skating sports. Pattern of injuries and groups at risk

One hundred and eighty-two patients presented with 200 inline-skating injuries over a 30-month period. Of these, 14% were admitted to hospital, 10% required operative treatment. Fractures (49%), contusions/lacerations (27%) and capsular/ligamentuous injuries (16%) were the most prevalent types of injury. Children had an even higher risk of sustaining fractures (62%). Falling on the extended arm caused 44% of all injuries. Thirteen percent resulted from torque mechanisms of the leg, whereas direct trauma to elbow or knee (5% each) were uncommon injury mechanisms. Injuries of the elbow, forearm, wrist and hand accounted for 55.5% of all cases and 71% of all fractures. Head (13%), knee (9.5%) and ankle (9%) were other regions frequently involved. Protective equipment was often used only for uninjured regions, whereas the injured regions had most often been left unprotected.     

A case report of Atasoy antenna procedure

A 25-year-old man presented with hook nail and painful atrophic pulp over the tip of the terminal phalanx of the right thumb 3 months following a crush injury. Lateral nail folds were poorly defined and the nail was curved. The patient was unable to pick up objects with a precision pinch. Reconstruction was performed with Atasoy antenna procedure. One year later, normal pulp contour of the injured thumb was restored and appearance of the nail was normal.     

The prognostic importance of calcitonin screening in familial medullary thyroid carcinoma

A prospective study of 20 patients with traumatic amputations of the fingers and a thumb was carried out during a six week period at Mpilo Central Hospital, Bulawayo. Most of the adult injuries (17 patients) resulted from industrial accidents (76.5 pc) while two out the three children sustained their injury from domestic accidents. Inadequate safety precaution, ignorance and human error contributed significantly to the injuries. Safety education and preventive measures both at home and in industry should be inoculated into the daily life of individuals.     

Evaluation and treatment of posterior cruciate ligament injuries

Twenty-eight low median nerve injuries and 23 low ulnar nerve injuries were repaired using intraneural fascicular dissection and electrical fascicular orientation. Eleven freshly lacerated nerves were seen within 48 hours after injury; 40 nerve lacerations were chronic. Fascicular orientation between sensory and motor fascicles at the proximal nerve end could be accurately differentiated in 47 nerves (92%) independent of whether it was acute or chronic. At the distal nerve end in fresh lacerations, the motor fascicles could be determined conclusively by muscle contraction with sequential electrical stimulation of the fascicles. In chronic nerve lacerations, the distal fascicles could be estimated anatomically after internal neurolysis. After fascicular orientation, nerves were repaired with end-to-end group fascicular suture or interfascicular sural nerve grafting. Twenty-four nerves repaired with end-to-end suture and 13 nerves repaired with nerve grafting were monitored more than 25 months. Satisfactory sensory results (i.e., S3+ or S4 functions) were obtained in 29 nerves (78%) and M4 or M5 motor functions were achieved in 29 nerves (78%). There were no patients who needed additional tendon transfers to reconstruct thumb opposition or to correct claw finger deformity. These results suggest that low median or ulnar nerve lacerations, whether acute or chronic, partial or complete, may be successfully repaired with the aid of electrical fascicular orientation with or without intraneural fascicular dissection.     

How many severely injured multiple-trauma patients can benefit from the biomechanical advantage of early mobilization following femoral intramedullary nailing?

The benefit of early operative stabilization of femoral fractures is established in patients with multiple injuries. In the last few years the unreamed femoral nail is favoured for internal fixation of femoral fractures despite pathophysiological concerns. The foremost advantage of femoral nails compared with plate fixation is the possibility of early full weight bearing. The aim of this retrospective study was to investigate, under consideration of the severity of injury, the extent of injury, and the clinical course, if multiple injured patients with concomitant femoral fractures benefit from the preferred intramedullary nailing with early weight bearing. Three hundred and two (23.8%) out of 1271 multiple injured patients (ISS > 17) had a concomitant femoral fracture. Fourty-seven out of 302 patients were children under 16 years of age, remaining 255 patients. Eighteen out of 255 patients died within the first 21 days after trauma and 66 patients required mechanical ventilation for more than three weeks (171/255). Thirty patients suffered from severe head injury (AIS-head > 3) and seven from severe pulmonary contusion with concomitant abdominal injury (134/255). Two patients had grade III open femoral fractures with vascular injury. Ipsilateral unstable pelvic fractures were seen in 11 patients, seven patients had ipsilateral intraarticular femoral fractures, and ipsilateral intraarticular fractures of the lower leg or foot were observed in 40 patients (74/255). The results demonstrate, that only 74 (29%) out of 255 multiple injured patients (> 16 years of age) had a theoretical benefit of early weight bearing. Seventy percent of the patients did not benefit from intramedullary nailing considering full weight bearing. With regard to pathophysiological concerns alternative methods of fracture fixation should be discussed for these patients. Primary fracture fixation with external fixators and secondary internal fixation proved to be a save alternative method. The complication rate of plating is comparable to intramedullary nailing but associated with less severe systemic risks. Primary plating of femoral fractures would not delay mobilization of most multiple injured patients.     

Ender nailing of acute humeral shaft fractures in multiple injuries

From January 1987 to April 1993, 25 multiply injured patients were treated with closed intramedullary Ender nail fixation of the humeral shaft. Criteria for the procedure were humeral diaphyseal fractures with associated multiple injuries. Seventeen distal and mid-shaft fractures were treated via a modified anterograde approach in which the rotator cuff is not violated. Eight proximal third fractures were treated via the standard retrograde approach. Postoperative follow-up averaged 36 months. Full range of motion was attained 17 of the 25 patients. Of the eight remaining patients, three with a slightly limited range of motion achieved full range of motion following nail removal; three had preoperative radial nerve palsy which resolved within 1 year, and two patients required follow-on plating. In 92 per cent (23 of 25) there were no incidences of infection or non-union. Flexible nails avoid complications of reaming. The modified anterograde approach allows excellent shoulder motion since it does not violate the rotator cuff. Ender nails provide excellent fixation and clinical outcome in the multiply injured patient and are cost effective compared with interlocking nails.     

Subungual exostosis: a simple technique of excision

Subungual or Dupuytren's exostosis is a benign lesion of the distal phalanx that is prone to recurrence if incompletely excised. We report on a series of five patients treated with our simple excision technique. Despite sacrifice of a portion of the nail bed, the cosmetic appearance of the nail was excellent in four patients and good in one patient. There were no recurrences.     

The cataract extraction-refraction-implantation technique for IOL power calculation in difficult cases

We present an unusual case of polydactyly of the thumb. The patient, despite having a fully developed nail bed, had a duplication at the metacarpophalangeal level consisting of a single bony phalanx. The Wassel classification of polydactyly, which is the most commonly cited classification scheme, does not include this particular anomaly. In addition, there has been no reference to this type of polydactyly in the literature.     

In vitro efficacy of levofloxacin alone or in combination tested against multi-resistant Pseudomonas aeruginosa strains

PURPOSE: To describe the causes and outcomes of pediatric injuries using the emergency departments (ED) as a surveillance site. METHOD: Prospective, 14-day surveys of all injuries were conducted in the EDs of the two national trauma referral hospitals of Trinidad and Tobago. Data on patient demographics, type, cause, and outcome of injuries were collected. The chi 2 test for significance was used for categorical variables. RESULTS: Pediatric patients (< 20 years) accounted for 41.5% (714/1722) of injury visits. Of these, 62.6% were male and 17.4% were < four years old, 26.2% four to nine years, 31.1% 10 to 14 years, and 25.4% were 15 to 19 years old. Three patients (0.4%) died, 68.6% were discharged, and 31.0% admitted. Intentional injuries accounted for 13.9% of injuries. Of the intentional injuries, the assailant was significantly more likely to be known than not (P < 0.01). The most common causes of all injuries were: falls, 44.4%; blunt objects, 12.3%; sharp objects, 11.8%; motor vehicle (including pedestrians), 7.4%; poison, 3.6%; and burns, 1.7%. Injuries occurring in the home accounted for 46.2%; in school, 25.5%; sports/recreation, 11.1%; and at work, 4.5%. The most common injuries were: lacerations, 30.8%, contusions/abrasions, 26.7%, fractures, 18.8%; and sprains/dislocations, 9.4%. CONCLUSION: Pediatric injuries are a significant cause of morbidity and mortality in this country, accounting for almost one third of injured patients. Because of the low frequency of pediatric injury deaths, ED surveillance may be a more effective means of identifying high risk groups and activities for injuries. Data from EDs may be useful in other developing countries to develop injury prevention programs.     

Controversies in the treatment of fingertip amputations. Conservative versus surgical reconstruction

Fingertip amputations are the most common type of amputation injury in the upper extremity. These injuries are either seen in the emergency room or in an office setting. These lesions are very frequent and require precise wound care for optimal results. The longer finger and the thumb, being the most distal and independent mobile parts of the hand are affected very often by these kind of injuries. Treatment of fingertip injuries is a continuous focus of controversy among hand and orthopaedic surgeons. Different treatment options have been described, depending on the affected segment and finger, type of lesion, gender and age of the patient, location, size, and depth of the defect. The indications, advantages, and disadvantages of several reconstructive procedures for fingertip injuries have been described. The techniques themselves are not described in detail.     

Hand injuries in the users of hydraulic wood-cutters

This study has been carried out in order to suggest possible prophylactic recommendations. We investigated the type of injuries, the type of logsplitter used, the injury circumstances and the safety measures. Fifty-two patients were included. There were a total of 21 crushing injuries with amputations of fingers, hand, on forearm. Nine replantations, two revascularisations and seven amputations were carried out. Eighty-eight percent of the patients had their hand in the splitting area. Sixty-seven percent had not received any instructions on how to operate the machinery. In 58% of the cases two or more persons were operating the logsplitter and 40% of the machines had no emergency stop button. The hazards mentioned above influenced the injury frequence and severity. We therefore recommend improved prophylactic measures and precautions to be considered. For the old machines a campaign will be necessary, and for new logsplitters we recommend implementation of new standards.     

Gamekeeper's thumb: ulnar collateral ligament injury

Injury to the ulnar collateral ligament of the thumb, once a common chronic occupational injury occurring in British gamekeepers, is now most frequently an acute sports-related injury in skiers, football players and other athletes. Differentiation of complete versus partial tears of the ligament is crucial because the treatment for complete tears is surgical. Radiographic evaluation, while important, has a limited role. Partial ligamentous tears, or those associated with uncomplicated avulsion fractures of the proximal phalanx, can be adequately treated by the family physician using simple shortarm thumb spica casting.     

Fractures in childhood in Khartoum

A prospective study of fractures in 231 children received at Khartoum North Teaching Hospital(KNTH) was carried out for a period of six months. The incidence of child fracture rated as one per day, then it increased from the age of 5 years onwards in boys and between 6 and 8 years in girls. Most injuries were sustained during the day time, especially between late afternoon and sunset. 82% of injured children presented to a medical facility, while 18% were taken to native healers first. Non-road traffic accidents accounted for 84% of the fractures mainly due to sports, domestic injuries and falls; whereas road traffic accidents were 16% and occurred mainly in pedestrians. Forty three percent of the fractures needed only first aid and splintage while 42% needed closed reduction. Thirty one percent of all patients were treated as inpatients. The long bones were affected in 91% of all fractures, the commonest site being the distal end of the forearm (26%), followed by supracondylar fracture of the humerus (15.6%). In the upper limb, left-sided fractures predominated. The epiphyseal injuries were 3.5% of all fractures, mainly at the distal radial epiphysis. Boys were commonly affected between 13-15 years of age. Open fractures constituted 9.8% of the series and were mainly due to traffic accidents in town dwellers, the most vulnerable bones were those of the leg and foot. Pathological fractures accounted for 2.2% and were due to bone cysts and osteogenesis imperfecta. The problem of child safety and the preventive measures need to be more stressed.     

Replantation of degloved skin of the hand

The treatment of a degloving injury is one of the most difficult problems in hand surgery. Various reconstructive procedures have been adopted in the past years, all with poor results. Between 1988 and 1995, nine patients with degloving injuries of the hand and fingers were treated by microsurgical replantation. The injury involved the thumb in three patients, the ring finger in three patients, the little finger in one patient, and multiple fingers in two patients. Successful complete revascularization was obtained in seven patients. In one case a superficial necrosis of the replanted thumb skin occurred with good preservation of the subcutaneous layer. In one patient with a degloving injury involving multiple fingers, revascularization was achieved only in the middle finger, and the first ray was secondarily resurfaced by a free flap from the foot. In our experience revascularization of the degloved skin does represent the best solution and must be managed as an emergency procedure. Coverage obtained in this way offers the best cosmetic result and allows early mobilization with good recovery of joint movement. Reestablishing sensibility is more difficult. It is not always possible to suture the nerves damaged by the trauma, and even when a careful primary nerve anastomosis is performed, the results often are unsatisfactory, probably because of the avulsive mechanism of nerve injury.     

Analysis of Construction Worker Injuries That Do Not Result in Lost Time

Attempts to examine the root causes of injuries in the construction industry have been largely focused on fatalities and other serious injuries. These efforts were undertaken with the assumption that the root causes of serious injuries could lead to identifying approaches that could prevent the recurrence of similar injuries in the future and that these approaches would also be successful in eliminating many minor injuries. While some injuries may be either minor or serious depending on small differences in worker position, etc., that assumption does not appear to be valid for most injuries. The trends of causes leading to minor injuries are often quite different from those resulting in serious injuries. With this assumption, an examination was conducted to profile nearly 136,000 construction worker injuries, most of which did not result in lost time. Results indicate that these injuries, not resulting in lost time, generally do not fit the profile of injuries that result in fatalities or that are serious. Over half of the injuries in the present study were associated with lacerations (usually of the fingers and hand) and injuries sustained by the lumbar spine, upper extremities, or eyes. The percentage of injuries that involved lacerations was considerably higher for construction than for all other industries. The costs of injuries were found to be quite varied, depending on the part of the body that was injured.     

Interface pressure measurements of support surfaces with subjects in the supine and 45-degree Fowler positions

The results of treatment of 35 intraarticular distal fractures of the femur are presented. Treatment was performed in 8 cases with a condylar plate, in 8 cases with dynamic compression screw (DCS), in 2 cases with two plates, in 9 cases with screws only, and eight times the fracture was treated with a combination of lag screws and locking nail. Examination took place at an average of 45.5 months after the accident. 19 patients had an isolated fracture, 8 patients one accidental injury and 8 patients had more than one fracture or were polytraumatised. In 75% of the patients treatment lasted for between day 1 and 5. We found 17.1% open fractures and had to face infections in 5.7% (two cases). Bone healing occurred in all fractures, the reported infections could be overcome by early revision and the use of gentamycin-PMMA beds. It is remarkable that locking nails were successfully used in 8 cases of fractures with intraarticular component of the distal femur.     

Clinical significance of determining serum soluble IL-6 receptor concentration in plasma cell dyscrasias

The authors analyze results of treatment of 778 children with malignant and benign tumors of the bones, pseudoarthroses, amputations of lower extremities and fingers, injuries of the tendons, vessels and contused-lacerated wounds of distal phalanges of fingers. The possibility to use a precision technique for the reconstructive operations of the vessels in children is shown.     

Fractures of the facial skeleton in Tabuk North West Armed Forces Hospital: a five year review

A five-year review of nine hundred and eighty maxillofacial injuries seen and treated at the Armed Forces Hospital, Tabuk, Saudi Arabia is presented. The dominant age group range was 21-30 years. There were almost twice as many maxillary fractures as mandibular fractures. The most common aetiology was road traffic accidents (RTA), followed by sport traumas. Facial lacerations and contusions followed by neurologic and orthopaedic injuries were the most common concomitant injuries.     

An epidemic of roller-blade injuries in children

Roller blading is a new and increasingly popular leisure activity in many countries. We reviewed 110 consecutive patients with roller-blade injuries between 1 January and 30 June 1996. The patients ranged from 4 to 14 years in age (mean 6.5 years). Eighty-three (75.4%) sustained injuries to the upper limb and 27 (24.5%) injured the lower limb. Fifty-six patients, were girls and 54 were boys. Of the 110 patients, 79 (72.7%) sustained fractures, 28 (25.4%) soft tissue injuries and 3 (2.7%) dislocations. Eighty-three (75.4%) of the patients wore no protective equipment on the limbs. Four months following injury 103 (93.6%) patients were fully recovered. The mean duration of school absence was 3 days. Subsequently 101 children returned to using roller-blades following injury. Seventy-three (66.3%) of these now use protective equipment. We found that injuries were unrelated to age or duration of roller-blading experience or to the brand-name of roller blades used, and that most of our patients wore no protective equipment at the time of injury.
