A cumulative positive fluid balance higher than 1100 ml/24 h was independently associated with mortality in patients with cancer. These findings highlight the importance of improving the evaluation of these patients' volemic state and indicate that defined goals should be used to guide fluid therapy.
Peroneal tendon disorders are common causes of lateral and retromalleolar ankle pain. For irreparable tears of the tendon, a salvage procedure is indicated with segmental resection followed by reconstruction with tenodesis, tendon transfer, or bridging the defect using allograft or autograft. Although there is insufficient evidence to guide which of these treatment options provides the best outcomes, reconstruction with tendon allograft has provided satisfactory clinical results and is effective for pain relief and restoration of tendon function. However, there are concerns about the use of tendon allografts which include its cost and availability, disease transmission, delayed incorporation, and stretching of the graft. The aim of this study is to present the surgical technique for the reconstruction of the peroneus brevis tendon tears using semitendinosus tendon autograft as an alternative to the allograft and report the short-term results of three cases.
OBJECTIVE:We describe a new technique for removing the distal fragments of broken intramedullary femoral nails without disturbing the nonunion site.METHODS:This technique involves the application of an AO distractor prior to the removal of the nail fragments, with subsequent removal of the proximal nail fragment in an anterograde fashion and removal of the distal fragment through a medial parapatellar approach. Impaction of the fracture site is then performed with a nail that is broader than the remaining fragmented material.RESULTS:Nails were removed from five patients using the technique described above without any complications. After a mean follow-up period of 61.8 months, none of these patients showed worsened knee osteoarthritis.CONCLUSION:The original technique described in this article allows surgeons to remove the distal fragment of fractured femoral intramedullary nails without opening the nonunion focus or using special surgical instruments.
Background: Zone 1 fractures of the proximal fifth metatarsal are usually treated nonsurgically using some type of immobilization. The aim of this study was to compare clinical and functional outcomes, time to return to prior activity levels, and rate of bone healing when using a hard-soled shoe (HSS) vs a controlled ankle motion (CAM)–walker boot (CWB). Methods: Seventy-two consecutive patients with zone 1 fractures of the fifth metatarsal base were treated conservatively with either an HSS or CWB by 2 different providers. We included 57 women and 15 men, average age of 41.3 (range, 16-88) years. Radiographic findings, visual analog scale (VAS) for pain, and American Orthopaedic Ankle & Foot Society (AOFAS) midfoot score were assessed. Patients were followed at 4, 8, 10, 12, and 24 weeks or until asymptomatic and able to return to prior level of activities. Statistical analysis was performed using Mann-Whitney U, Fisher exact, and chi-square tests. P values <.05 were considered significant. Results: Age and gender distributions were similar in both groups ( P = .23 and P = .57). Patients had similar VAS and AOFAS scores after 8 ( P = .34 and P = .83) and 12 ( P = .87 and P = .79) weeks. Average time for bone healing was significantly faster using the CWB (7.2 weeks) when compared to the HSS (8.6 weeks) ( P < .001). The average time to return to prior level of activities was similar in both groups (8.3 weeks for CWB and 9.7 weeks for HSS) ( P = .11). Fracture displacement was equal in both groups, with a mean of 1.9 mm of displacement in patients using the HSS, and a mean of 1.6 mm in those using the CWB ( P = .26). Conclusion: Zone 1 fractures of the proximal fifth metatarsal can be treated conservatively with either a hard-soled shoe or a CAM-walker boot. Even though patients treated in the CAM-walker boot demonstrated earlier signs of complete healing, similar clinical and functional results were achieved with both treatments. Level of Evidence: Level III, retrospective comparative series.
Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Lapidus procedure (LP) for hallux valgus (HV) requires an adequate control of first metatarsal (M1) sagittal alignment to avoid dorsiflexion. Otherwise, clinical and functional impairment, including transfer metatarsalgia may occur. This study aimed to evaluate the effects of pre- and postoperative measurements of M1 sagittal alignment on clinical and functional outcomes, and whether these variations would lead to transfer metatarsalgia or not. Methods: 29 patients (36 feet) with a mean follow-up of 20 months after LP were reviewed. Clinical and functional data were assessed with the VAS for pain, AOFAS, LEFS and SF-12. SF-12 comprises physical and mental health scales (PCS-12 and MCS-12, respectively). Transfer metatarsalgia diagnosis was based on the clinical exam. M1 sagittal alignment analysis was based on the first metatarsal declination angle (FMDA) and Meary Angle (MA). Decrease of FMDA means that the M1 dorsiflected (Figure 1). Intermetatarsal angle (IMA) and hallux valgus angle (HVA) were assessed. Radiographic, clinical and functional measurements were compared. Intraclass Correlation Coefficients (ICC) were calculated for FMDA and MA. Linear regression was used to assess the association of Δ-FMDA and Δ-MA with clinical and functional questionnaires. Based on that, we assessed our sample at different cut-off points to evaluate whether a given Δ-FMDA and/or Δ-MA measurement was significantly related to the Δ-Questionnaires. Results: Pre- and postoperative ICC of FMDA was 0.90 and 0.91 and MA was 0.94 and 0.88, respectively. FMDA showed significant variation after the LP, but MA did not. IMA and HVA improved significantly. Significant clinical and functional improvement were observed, except in MCS-12. No patient developed transfer metatarsalgia. A direct correlation was found between ΔFMDA with Δ-PCS-12 and Δ-LEFS (p=.028 and p=.02, respectively), meaning that excessive dorsiflexion of M1 as measured by FMDA led to a decrease in PCS-12 and LEFS. We found that at the cut-off point of quartile 50%, in which our sample was divided equally, patients with Δ-FMDA below 3.2 degrees of dorsiflexion had significantly improved results on Δ-PCS-12 compared to those with greater values (p=.029) (Figure 2). Conclusion: The present study showed that excessive dorsiflexion of M1 led to decreased outcome scores as measured by PCS- 12 and LEFS. It supports that M1 dorsiflexion should be avoided after the LP. However, slight dorsal deviation can occur and, even so, satisfactory outcomes can be obtained. Further prospective and comparative studies with larger populations are required to evaluate the effects of M1 inclination on clinical and functional outcomes.
