Achieving interlocking nails without using an image intensifier.

Interlocking nails are commonly performed using an image intensifier. These are expensive and are not readily available in most resource-poor countries of the world. The aim of this study was to achieve interlocking nailing without the use of an image intensifier. This is a prospective descriptive analysis of 40 consecutive cases seen with shaft fractures of the humerus, femur, and tibia. Fracture fixation was done using Surgical Implant Generation Network (SIGN) nails. Forty limbs in 34 patients were studied. There were 12 females and 22 males, giving a ratio of 1:2. The mean age (years) was 35.75+/-13.16 and the range was 17-70 years. The studied bones were: humerus 10%, femur 65%, and tibia 25%. The fracture lines were: transverse 40%, oblique 15%, and communited 45%. Fracture grades were: closed 90%, grade I, 5%, grade II, 2.5%, and grade IIIA, 2.5%. Surgical approaches were: antegrade 62.5% and retrograde 37.5%. Indications for fixation were: recent fracture 92.5%, non-union 5%, and malunion 3%. Methods of reductions were: open 85% and closed 15%. The mean follow-up period (years) was 1.50+/-0.78. The union time averaged 3 months. Complication was mainly screw loosening due to severe osteoporoses in one case. It is, therefore, concluded that, with the aid of external jigs and slot finders, interlocking can be achieved without an image intensifier.

Compartmental pressure in adults with tibial fracture.

Acute compartment syndrome is associated with tibial fractures and failure to diagnose it leads to grave consequences. This study was conceived with the aim of determining the intra-compartmental pressure in adults with closed tibial fractures and intended to provide early diagnosis of acute compartment syndrome. The Whitesides injection method was used, using hospital [corrected] available materials. The intra-compartmental pressure in the anterior and deep posterior compartments of 52 patients with closed tibial fractures was measured at presentation and 4 hourly for 24 h. In three patients, the pressure was very high, and the differential pressure (i.e. the difference between the diastolic blood pressure and the intra-compartmental pressure) was less than or equal to [corrected] 30 mmHg, which was diagnostic of acute compartment syndrome. They were all treated by fasciotomy. It is concluded that Whitesides' [corrected] method can be used to diagnose acute compartment syndrome. The apparatus is easy to set up, cheap [corrected] and therefore ideal for use in our environment where sophisticated devices of tissue pressure measurement are not available.

Normal leg compartment pressures in adult Nigerians using the Whitesides method.

In Caucasians, the range of normal intracompartmental pressure of the leg is from 0 mmHg to 15 mmHg. In the literature, such measurements have not been done in Africa to identify normal leg intracompartmental pressures. We have sought to identify the normal range of pressures in such a population of Nigerians, and to demonstrate the reproducibility of the Whitesides injection technique with materials that are easily available in most hospitals so that compartment syndromes could be identified promptly and inexpensively in developing countries. We performed a 16-month hospital-based prospective study at Wesley Guild Hospital in Ilesa, Osun State, Nigeria, to measure the intracompartmental pressures in the anterior and deep posterior compartments of 49 contralateral uninjured legs of patients with closed contralateral tibial fractures, measured at presentation. The Whitesides infusion technique was used with the aim of determining the normal range of compartmental pressure in Nigerians. The anterior compartment pressures ranged from 3 mmHg to 18 mmHg with a mean 7.6 +/- 2.6 mmHg. The pressure in the deep posterior compartment ranged from 3 mmHg to 14 mmHg with mean of 7.4 +/- 2.7 mmHg. The values are similar to those reported in the literature. There was no statistically significant difference between the pressures in the two compartments (p = 0.668).
