Background: Flexible flatfoot (FF) is a common foot deformity that can often consist of foot pain. Surgical treatment is designed to lengthen the lateral column.

Objectives: To resolve whether radiographic standing feet measurements of normo-plantigrade feet and FF, symptomatic or not, differ and to determine whether the lateral column is shorter.

Methods: The study comprised 72 patients (127 feet) consecutive patients, 18 years of age and older, who were divided into three groups: normal feet (56), asymptomatic FF (29), and symptomatic FF (42). All patients had a standing anterior posterior (AP) and lateral radiographs. AP images were used for the measurement of the talocalcaneal angle, talar-1st metatarsal angle, and talonavicular coverage. Lateral X-rays were used to estimate the talocalcaneal angle, talar-1st metatarsal angle, calcaneal pitch, naviculocuboid overlap, and column ratio.

Results: All three of the AP radiograph measurements differed among groups, and higher values were measured in the symptomatic FF group. Post hoc analysis found that the talonavicular coverage and the talocalcaneal angles also differed between symptomatic and asymptomatic FF patients. While some lateral measurements differed within groups, only the lateral talar-1st metatarsal angle distinguished between asymptomatic and symptomatic patients. The lateral column length was not found to be shorter among FF patients, weather symptomatic or not.

Conclusions: Only the talonavicular coverage, the AP talocalcaneal, and the lateral talar-1st metatarsal angles were found to differ between asymptomatic and symptomatic FF patients. The lateral column was not found to be shorter

Background: Intraarticular injections for the local treatment of osteoarthritis are widely used in the office or hospital setting. Septic arthritis is a potential catastrophic complication of intraarticular injection, as bacterial arthritis of any cause is associated with up to 15% mortality and residual impairment of joint function in up to 50% of survivors. There is lack of evidence regarding the precautions that should be taken to avoid such a complication, as well as how often it is encountered.

Objectives: To report our experience with the clinical presentation, diagnosis and treatment of knee septic arthritis following intraarticular injections. 

Methods: We followed six patients who were admitted to the hospital and underwent surgery for the treatment of pyogenic arthritis following injection to the knee joint in outpatient clinics.

Results: All but one patient were over 70 years old with comorbidities. Three patients were injected with steroid preparations and three with hyaluronic acid several days before admission. In all six patients the infection was treated surgically and three of them had undergone more than one operation during their hospitalization. Four of the six patients were treated by means of an open arthrotomy and synovectomy, and the other two were treated successfully with arthroscopic lavage and synovectomy. One patient underwent an above-knee amputation due to septic shock and died after several days.

Conclusions: Despite the rarity of this complication, surgeons must be aware of the possibility of pyogenic arthritis when administering injections, especially in elderly patients with serious underlying medical conditions.

Background: Gunshot wounds impose a continuous burden on community and hospital resources. Gunshot injuries to the extremities might involve complex soft tissue, bone, vascular, musculotendinous, and nerve injuries. A precise knowledge of anatomy is needed to evaluate and treat those injuries.

Objectives: To review our experience with gunshot wounds to the extremities.

Methods: We retrospectively reviewed all cases of gunshot wounds to the limbs in a civilian setting treated in our institution during 2003–2005. Altogether, we evaluated 60 patients with 77 injuries.

Results: Of the 60 patients 36 had fractures, 75% of them in the lower extremity and 81% in long bones. The most common fixation modality used was external fixation (33%), followed by intramedullary nailing (25%). This relatively high percentage of fracture treated with external fixation may be attributed to the comminuted pattern of the fractures, the general status of the patient, or the local soft tissue problems encountered in gunshot wounds. About one-fifth of the fractures were treated by debridement only without hardware fixation. We treated 10 vascular injuries in 8 patients; 6 of them were injuries to the popliteal vessels. Fractures around the knee comprised the highest risk factor for vascular injuries, since 5 of the 12 fractures around the knee were associated with vascular injury requiring repair or reconstruction. There were 13 nerve injuries (16.8%), most of them of the deep peroneal nerve (38%). Only three patients had concomitant nerve and vascular injuries. The overall direct complication rate in our series was 20%.

Conclusions: Treating complex gunshot injuries requires a team approach, necessary for a favorable outcome. This team should be led by an orthopedic surgeon knowledgeable in the functional anatomy of the limbs.

Background: Unicompartmental knee replacement has become a surgical alternative for treating isolated medial or lateral osteoarthritis of the knee or avascular necrosis of the femoral condyls.

Objectives: To evaluate the short-term results of the Oxford Phase 3® unicompartmental knee replacement for unicompartmental knee arthrosis or avascular necrosis of the medial

femoral condyle.

Methods: During the period 2003–2005 a total of 59 patients (59 knees) underwent medial Oxford Phase 3® unicompartmental knee replacement in our unit. The patients were interviewed and examined, and standing anteroposterior and lateral X-rays were taken. All patients completed the Western Ontario and McMaster Universities Index of Osteoarthritis and the Short Form 12 questionnaire, and the International Knee Society score was evaluated. The data were collected and statistical analysis was performed.

Results: X-rays were performed and scores for the WOMAC[1] and IKS[2] were assessed for 42 patients (31 females, 11 males). At an average of 32 months after surgery, the total WOMAC score was 30. The mean SF[3]12 physical score was 38 and the mean SF12 mental score was 51. The mean IKS score was 166. Ninety-one percent of the patients had active flexion of 120 degrees or more. Of 59 knees 7 were converted to total knee arthroplasty – all of them within the first 2 years of starting the procedure and all of them in relatively young patients.

Conclusions: Despite the higher revision rate to TKR[4] in this study, our findings confirm the short-term results reported in other studies of the Oxford medial unicompartmental knee and our early failure rate could be explained by a performance learning curve. This study confirms that this bone-preserving procedure should be considered in end-stage isolated unicompartmental osteoarthritis or avascular necrosis by surgeons who have the adequate training and experience.
