OBJECTIVES: For intramedullary nailing of tibial shaft fractures, a recent study has determined that the entry site should be just medial to the lateral tibial spine at the anterior margin of the articular surface. Gaining access to this site is often through a medial parapatellar or transpatellar approach. Several studies have indicated that a transpatellar approach may contribute to anterior knee pain. Our study sought to use anatomic measurement to determine the ideal incision site for insertion of an intramedullary tibial nail. DESIGN Part I: survey of Orthopaedic Trauma Association (OTA) members. Part II: anatomic study. SETTING: A Level I trauma center in Sacramento, California. PARTICIPANTS: Part I: OTA members. Part II: a group of 56 healthy volunteers. INTERVENTION: Part I: questionnaire sent to OTA members. Part II: clinical examination and radiographic analysis. MAIN OUTCOME MEASUREMENTS: Part I: responses to questionnaire. Part II: anatomic measurements. RESULTS: Part I: based on a questionnaire, OTA members use at least one or more approaches to access their preferred tibial nail entry site. Fifty-seven percent use only one type of approach in all cases. Part II: the authors performed a clinical and radiographic study in 56 volunteers (112 knees) to determine the relationship of the lateral tibial spine to the patellar tendon. On the basis of this information, the tendon was divided into thirds to account for the three most common surgical approaches. The entry site was in the lateral zone in 29 knees, the middle zone in 75 knees, and the medial zone in 8 knees. If divided equally into purely a medial or lateral zone to avoid a transpatellar approach, the starting point fell into the medial zone in 42 knees and the lateral zone in 70 knees. CONCLUSIONS: Individual variations in patellar tendon anatomy should be considered when choosing the proper entry site for tibial nailing. Based on the assumption that the ideal entry point for tibial nailing is just medial to the tibial spine at the anterior margin of the articular surface, a preoperative fluoroscopic measurement before incision can guide the surgeon as to whether a medial parapatellar, transpatellar, or lateral parapatellar approach provides the most direct access to this entry site. The routine use of a single approach for all tibial nails may no longer be justified. 相似文献

Intraarticular anatomic risks of tibial nailing. 总被引:5,自引:0,他引:5
OBJECTIVE: To identify the risks to intraarticular structures of the knee during tibial portal creation and to identify the safe zone for tibial nail placement. STUDY DESIGN: Cadaveric anatomic. LOCATION: University trauma center. METHODS: Forty fresh frozen cadaveric knees were studied to elaborate the risks of tibial portal creation and nail placement to the intraarticular structures of the knee. Nails were placed through medial and lateral parapatellar approaches, and the distance from the nail portal to the intraarticular structures of the knee was measured. A safe zone for portal placement was determined. RESULTS: The tibial portal location averaged 4.4+/-3 millimeters lateral to the midline of the plateau. Actual intraarticular structural damage occurred in 20 percent of the specimens; however, an additional 30 percent demonstrated the nail to be subjacent to one of the menisci. A lateral paratendinous approach placed the lateral articular surface at most risk, and a medial paratendinous approach placed the medial meniscus at most risk. The safe zone for nail placement was identified and is located 9.1+/-5 millimeters lateral to the midline of the plateau and three millimeters lateral to the center of the tibial tubercle. The width of the safe zone averaged 22.9 millimeters and was as narrow as 12.6 millimeters. CONCLUSION: Damage to the intraarticular structures of the knee is possible during tibial nailing with a superior portal. The safe zone for nail placement is small and can be exceeded if a reamed nail is used. The safest starting point for tibial nailing should be slightly lateral to the center of the tibial tubercle. 相似文献

Forty-four consecutive diaphyseal extra-articular tibial fractures (43 patients) were treated with intramedullary interlocking nail. There were 35 men and eight women with a mean age of 38 years. Average follow-up was 25 months. Cases were divided into two groups: anterior-knee-pain group, 20 knees; and no-pain group, 24 knees. The lateral projection radiographs of their tibiae were scrutinised for precise bony portal point. The distance between articular surface and tibial tubercle was divided into three equal zones. In the superior zone, six had pain and six did not. In the central zone, eight had pain and 15 did not. In the inferior zone, six had pain and three did not. There was no significant difference between anterior knee pain and the three zones of the bony entry, age, gender, mechanism of injury, dynamisation, nail protrusion, approach and union time. We conclude that bony entry point in the sagittal plane is not a significant prognostic indicator for anterior knee pain following intramedullary tibial nailing. 相似文献

Intramedullary nailing is one viable option for treating fractures of the tibia with a short, proximal segment. For a procedure being carried out with the knee in a semi-extended position, either a suprapatellar or parapatellar approach may be used. The objective of this study is to demonstrate whether the entry point for tibia nails is obtainable through suprapatellar or parapatellar approaches and to evaluate the most frequent injuries of the knee with these two approaches.Materials and methodsPaired legs from 10 fresh frozen cadavers were used. An arthroscopy was performed in each knee, documenting the status of the knee prior to the insertion of the tibia nail. In a random manner, the left or right leg underwent nailing with a suprapatellar or parapatellar approach in a semi-extended position. Fluoroscopy was utilized in each case to localize the entry point, and a tibia nail was inserted in all cases. A knee arthrotomy was then performed and the status of the following structures was assessed: patella and trochlea cartilage, tibia plateau cartilage, inter-meniscal ligament, lateral and medial meniscus, and the ACL.ResultsThe correct fluoroscopy entry point was achieved in all of the specimens (20). Three legs (3/10) with parapatellar approach had intra-articular disruption. In legs with a suprapatellar approach, patellar cartilage and trochlea cartilage damage was found in two of the specimens, respectively. There was one specimen with cartilage damage in the parapatellar approach. There were no meniscal injuries. Partial laceration of the intermeniscal ligament was found in three of the knees for each approach. One ACL injury was found in the suprapatellar group. Mean distance from the entry point to major structures is not significantly different with either approach. (p = 0.45).ConclusionsA good fluoroscopic entry point can be achieved using either the parapatellar or suprapatellar approach. The parapatellar approach for tibia nailing has similar rate of soft tissue damage compared to the suprapatellar approach. The suprapatellar approach damaged the cartilage in one-third of the cases and if cartilage injury occurs with the parapatellar approach, this is located in a low risk area. 相似文献

The risk of articular penetration during tibial nailing is well known, but the incidence of unrecognised damage to joint cartilage has not been described. We have identified this complication in the treatment of tibial fractures, described the anatomical structures at risk and examined the most appropriate site of entry for tibial nailing in relation to the shape of the bone, the design of the nail and the surgical approach. We studied the relationship between the intra-articular structures of the knee and the entry point used for nailing in 54 tibiae from cadavers. The results showed that the safe zone in some bones is smaller than the size of standard reamers and the proximal part of some nails. The structures at risk are the anterior horns of the medial and lateral menisci, the anterior part of the medial and lateral plateaux and the ligamentum transversum. This was confirmed by observations made after nailing 12 pairs of cadaver knees. A retrospective radiological analysis of 30 patients who had undergone tibial nailing identified eight at risk according to the entry point and the size of the nail. Unrecognised articular penetration and damage during surgery were confirmed in four. Although intramedullary nailing has been shown to be a successful method for treating fractures of the tibia, one of the most common problems after bony union is pain in the knee. Unrecognised intra-articular injury of the knee may be one cause of this. 相似文献

Three-dimensional knee motion before and after high tibial osteotomy for medial knee osteoarthritis 总被引:1,自引:1,他引:0

Background High tibial osteotomy (HTO) is an established surgical option for treating medial knee osteoarthritis. HTO moves the mechanical
load on the knee joint from the medial compartment to the lateral compartment by changing the leg alignment, but the effects
of the operation remain unclear. The purpose of this study was to evaluate the change in three-dimensional knee motion before
and after HTO, focusing on lateral thrust and screw home movement, and to investigate the relationship between the change
in knee motion and the clinical results.
Methods A series of 19 patients with medial knee osteoarthritis who had undergone HTO were evaluated. We performed a clinical assessment,
radiological evaluation, and motion analysis at 2.4 years postoperatively. The clinical assessment was performed using the
Japanese Orthopaedic Association knee score.
Results The score was significantly improved in all patients after operation. Motion analysis revealed that lateral thrust, which
was observed in 18 of the 20 knees before operation, was reduced to 7 knees after operation. Regarding active terminal extension
of the knee, three patterns of rotational movement were observed before operation: screw home movement (external rotation),
reverse screw home movement (internal rotation), and no rotation. By contrast, after operation, only reverse screw home movement
and no rotation were observed; the screw home movement disappeared in all patients. In the knees with reverse screw home movement
after operation, the preoperative score was significantly lower than those in the knees with no rotation after operation.
Conclusions Kinetically, HTO was useful for suppressing lateral thrust in medial knee osteoarthritis, although the rotational movement
of the knee joint was unchanged. 相似文献

This study presents a modification of the medial parapatellar surgical approach for total knee arthroplasty. This approach separates the vastus mediatis muscle in the direction of its fibers beginning at the superior pole of the patella. One hundred eighteen consecutive total knee arthroplasty cases, performed by a single surgeon, were randomized prospectively to receive a medial parapatellar or midvastus muscle-splitting surgical approach. The frequency of lateral retinacular releases was recorded, patellar tilt and translation were measured, and quadriceps strength was tested. The midvastus muscle-splitting approach provided excellent exposure to all knees. Patellar stability and quadriceps strength were equivalent for the two approaches. It is concluded that the midvastus muscle-splitting approach is an efficacious alternative to the medial parapatellar approach for primary total knee arthroplasties. 相似文献

BackgroundPatellofemoral arthroplasty (PFA) is an emerging treatment for patients with isolated patellofemoral compartment osteoarthritis. The medial parapatellar approach is the standard arthrotomy but has been shown in total knee arthroplasty to damage the patellar blood supply and increase postoperative patellar instability. The lateral parapatellar approach is an alternative that may reduce the risk of these outcomes. The purpose of this study is to compare the radiographic measures of patellar tracking and patient-reported outcomes of the medial and lateral parapatellar approaches in PFA.MethodsBetween 2012 and 2019, a retrospective review was performed of 136 knees undergoing PFA at a single institution. Patients were separated by preoperative congruence angle and then surgical approach into 3 cohorts. Preoperative and postoperative patellar tilt and congruence angle were measured. Preoperative and minimum 6-month postoperative patient-reported outcomes scores were collected.ResultsThere were no significant differences in the mean postoperative congruence angle and postoperative patient-reported outcomes among the 3 cohorts. Mean postoperative patellar tilt was normalized only in the abnormal congruence angle/lateral approach group to 2.80° (standard error, 1.85).ConclusionCongruence angle was improved regardless of surgical approach. Patellar tilt was normalized only for the lateral approach in patients with abnormal preoperative congruence angle. There were no significant differences in preoperative and postoperative scores between groups except for preoperative 12-item Short Form Mental Health Survey scores. This study supports that the lateral approach offers improved postoperative patellar tilt compared to a medial approach for PFA while achieving similar patient-reported outcomes. 相似文献

OBJECTIVE: To identify the radiographic correlate of the anatomic safe zone for tibial portal placement. DESIGN: Cadaveric, anatomic, and radiographic study using twenty cadaveric knees. Kirschner wires were placed in the anatomic safe zone. Anteroposterior and lateral radiographs were taken to evaluate the portal placement. SETTING: Anatomy laboratory. OUTCOME MEASUREMENTS: Radiographic measurements of Kirschner wires placed in the anatomic safe zone. RESULTS: The safe zone for tibial nail placement as seen on radiographs is just medial to the lateral tibial spine on the anteroposterior radiograph and immediately adjacent and anterior to the articular surface as visualized on the lateral radiograph. There is some variance on the anteroposterior radiograph but no variance on the lateral radiograph. CONCLUSIONS: The placement of tibial nails in the superior portion of the tibia in the documented position generates the least risk to the intraarticular structures of the knee. 相似文献
