Chondral print on humeral head: an indirect sign of long head biceps tendon instability.

Long head biceps (LHB) tendon pathologies are becoming increasingly recognized causes of shoulder pain in the published literature. Instability of LHB presenting as dislocation or subluxation has been recently recognized as a possible cause of disabling pain or discomfort of the shoulder. A clinical diagnosis of LHB instability is very difficult and often confounding because of association with other shoulder pathologies. However, an early diagnosis of LHB instability is important in order to prevent the evolution of lesions of the biceps pulley until an internal anterosuperior impingement of the shoulder (ASI) and subscapular tear occur. The advent of arthroscopy contributed to enhance understandings. The goal of this article is to describe an arthroscopic sign, the chondral print on the humeral head, associated with a LHB instability, that when present can be very useful to help the surgeon to make the diagnosis of unstable LHB tendon.

Gerdy tubercle osteotomy in surgical approach of posterolateral corner of the knee.

Posterolateral corner (PLC) injuries of the knee are uncommon injury patterns that may result in significant degrees of functional disability. When surgery is necessary to address this injury a good knowledge of anatomy and a good surgical exposure is the mainstay. This report reviews the complex anatomy of the posterolateral corner (PLC) of knee and describes the osteotomy of Gerdy tubercle as a technical variant to approach this anatomical region. This surgical step allowing a good mobilisation of the multiple layers of ilio-tibial tract from distal to proximal makes an excellent exposure of the PLC structures with absence of morbidity.

Multilobulated popliteal cyst after a failed total knee arthroplasty.

Popliteal cyst is a rare finding after total knee arthroplasty (TKA), but when present, it might indicate a malfunction of the TKA related to generation of wear-particles, or loosening. We present a case of a multilobulated popliteal cyst developing in a patient 8 years after primary TKA. The cyst was associated with a mechanical prosthetic loosening. The primary complaint of the patient was pain in the posterior region of the knee. A two-stage procedure consisting of cyst excision at first, followed after 5 months by a revision TKA was performed. Intraoperatively, a darkish, multilobulated cyst with a well-defined thick wall filled with fluid containing polyethylene debris, communicating with the knee joint was found. After 3 years of follow-up, the patient was satisfied and walked without the support of a cane. The patient presented a satisfactory knee range of motion. Clinical, radiological and ultrasound investigations ruled out popliteal cyst recurrence. A dissecting popliteal cyst associated with a failed TKA should be excised because it contains polyethylene debris that constitutes an induced factor for prosthetic loosening. A two-stage procedure with quite a long time in-between, as presented in this paper, can be a useful alternative to manage such a problem, in particular in very old patients associated with other medical problems.

Posttraumatic coccygeal instability.

PURPOSE: To report the middle term results of partial coccygectomy in a consecutive series of 15 patients with chronic coccygodynia. METHODS: Fifteen patients with chronic coccygodynia were referred to our outpatient clinics. The patients were investigated with dynamic lateral radiography and magnetic resonance imaging (MRI). We diagnosed a posttraumatic coccygodynia with instability of the coccygeal segment and performed a partial coccygectomy after failure of the conservative treatment. RESULTS: All patients underwent subjective and objective assessment after a mean time of 2.8 years from surgery. There were 11 excellent, 3 good, and 1 fair results. The mean time of improvement was 15 weeks, and no further improvement was observed after 6 months. CONCLUSION: Partial coccygectomy is a good therapeutic option for posttraumatic coccygodynia. Dynamic radiography is a useful tool to differentiate posttraumatic from idiopathic coccygodynia. MRI may be useful for further evaluation of the patients after inconclusive dynamic radiography.

Anatomic anterior cruciate ligament reconstruction: the two-incision technique.

This article describes the anatomical two-incision reconstruction of anterior cruciate ligament (ACL) of knee. The major part of currently single incision tibial endoscopic techniques attempts to reproduce the most isometric anteromedial bundle of ACL. Often a relatively vertical femoral tunnel, respect to the notch, is drilled, which is not really efficacious in providing rotatory stability. The single incision technique was developed to obviate the necessity of the lateral femoral incision and dissection. This technical note describes a two-incision ACL reconstruction using an instrumentation, which avoids a large lateral femoral soft tissue dissection, and discusses the rational use of the two-incision ACL reconstruction technique.

Closed and open grade I and II tibial shaft fractures treated by reamed intramedullary nailing.

OBJECTIVE: To evaluate the results of closed and open grade I and II tibial shaft fractures treated by reamed nail and unreamed nailing. SUBJECTS AND METHODS: Between 1997 and 2000, 119 patients with tibial shaft fractures were treated with reamed tibial nails. Postoperatively 96 patients (70 closed and 26 grade I and II open fractures) were followed clinically and radiologically for up to 18 months. The nail was inserted either by patellar tendon splitting or by nonsplitting technique. The nail was inserted after overreaming by 1.5 mm. Postoperatively, patients with isolated tibial fracture were mobilized by permitting partial weight bearing on the injured leg for 6 weeks. Patients with associated ankle fractures were allowed to walk with a Sarmiento cast. RESULTS: Postoperatively, 6 (6.3%) patients developed a compartment syndrome after surgery. In 48 (50%) cases, dynamization of the nail was carried out after a mean period of 12 weeks for delayed union. Overall, a 90.6% union was obtained at a mean of 24 weeks without difference between closed or open fractures. Two (2.1%) patients with an open grade II fracture developed a deep infection requiring treatment. A 9.4% rate of malunion was observed. Eight (8.3%) patients developed screw failure without clinical consequences. At the last follow-up, 52% of patients with patellar tendon splitting had anterior knee pain, compared to those (14%) who did not have tendon splitting. CONCLUSION: Reamed intramedullary nail is a suitable implant in treating closed as well as grade I and II open tibial shaft fractures.

Leg textiloma. A case report.

OBJECTIVE: To report and highlight the potential diagnostic pitfalls and consequences of leg textiloma. CASE REPORT AND INTERVENTION: A soft tissue pseudotumor of the left leg diagnosed in a 58-year-old man is described. The lesion was caused by a retained surgical gauze after surgery for varicose veins. The surgical gauze had remained in the subcutaneous tissue for 3 years and led to the formation of a 3-cm, well-circumscribed, pseudotumoral foreign body granuloma which appeared like a soft tissue tumor. A surgical intervention was performed and the mass was excised. During the procedure an old surgical gauze was found. The histologic examination revealed that a large foreign body granuloma (pseudotumor) had developed in contact with foreign material birefracting under polarized light (gauze). No sign of malignancy was noted. CONCLUSION: Although no fatal complications have been described in the musculoskeletal localization, the diagnosis is difficult and costly. According to clinical presentation, a differential diagnosis should be made between a tumoral lesion, such as a sarcoma, or a pseudotumoral lesion, such as a gossypiboma. Focal myositis or infections should also be suspected.

Use of trochanteric nail for proximal femoral extracapsular fractures.

Proximal femoral extracapsular fractures have shown a significantly high morbidity and mortality rate at 1 year in cases of nonoperative treatment. The standard gamma nail was originally designed to provide stable fixation and allow early mobilization and weight bearing for elderly patients. The design of the standard gamma nail, however, appears to be associated with intraoperative or postoperative femoral shaft fractures in < or = 17% of patients, compromising the outcome. The trochanteric nail was developed to overcome the problems encountered with the use of the standard gamma nail. Between July 2000 and January 2001, 88 consecutive proximal femoral extracapsular fractures were treated with a trochanteric nail, Seventy-five patients (76 fractures) were observed clinically and radiographically for 2 years.

Extracorporeal shock wave therapy in runners with a symptomatic heel spur.

The aim of this paper is to assess the benefit to treat plantar fasciitis with low-dose energy extracorporeal shock wave therapy (ESWT) and the efficacy of such treatment to abate the painful symptoms allowing a rapid return to the running activity. Our study included 54 running athletes treated for plantar fasciitis associated with a heel spur who received four sessions (once weekly) of low-dose ESWT, and followed prospectively on average 45 days, 6 and 24 months after their last session. The clinical results were excellent in 59% of cases, good in 12%, satisfactory in 21% and distinctly unsatisfactory in 8%. No patient was observed a significant modification of the heel spur at the follow-up X-ray. The ultrasound examination at 24 months showed a disappearance of the inflammation signs in 61% of cases. A strong correlation between ultrasound improvement and clinical results were found. Low-energy ESWT seems to be a good mean to treat plantar fasciitis in runners with a 71% of good or excellent results and a persistent improvement lasting 24 months. A randomized multicentric study seems to be necessary to define the type of energy that should be used in the future to treat plantar fasciitis, in particular in the athletic patients, to allow a faster return to sports activities.

Medium-energy shock wave therapy in the treatment of rotator cuff calcifying tendinitis.

To evaluate the results of the treatment with medium-energy extracorporeal shock wave therapy (ESWT) in rotator cuff calcifying tendinitis. Fifty-four non-consecutive patients, who were referred to our institute for rotator cuff calcifying tendinitis, were managed with a standardized protocol in four sessions of medium-energy (0.11 mJ/mm2) ESWT administered with an electromagnetic lithotriptor. Pain was evaluated at the end of each session, functional state of shoulder was assessed at 1 and 6 months after the end of procedure. All patients underwent radiographs and sonography imaging. No systemic or local complications. Thirty-eight patients (70%) reported satisfactory functional results. Radiographs and sonographs showed a disappearance of calcium deposit in 29 patients (54%) and in 19 patients (35%) it appeared to be reduced more than a half. A correlation was found between residual calcium deposit and the clinical outcome, but some patients showed a reduced pain without modification of calcium deposit. These results were unmodified at 6 months follow-up. Our protocol of medium-energy ESWT provides good results overall about pain modulation.

Arthroscopic treatment of anterior shoulder instability using knotless suture anchors.

PURPOSE: In this study, we evaluated the results of arthroscopic stabilization of the shoulder using knotless anchors and the lesions associated with anterior-inferior labrum avulsion. TYPE OF STUDY: Retrospective clinical study. METHODS: Twenty consecutive patients affected with anterior unidirectional post-traumatic shoulder instability were treated with arthroscopic reconstruction using knotless anchors. During the surgical procedure, associated lesions such as superior labrum anterior posterior (SLAP) (15%) and rotator interval (15%) were repaired. The patients were evaluated at a mean follow-up of 43 months. RESULTS: Eighty percent of patients resumed sports activity without any limitation and 90% of patients were satisfied with the results of surgery. One patient (5%) had a recurrent dislocation; this patient resumed a contact sport activity despite medical advice. One patient (5%) related signs of shoulder insecurity at the extreme degree of abduction and external rotation; this patient had resumed sports activity with a moderate limitation and was the only patient who was not completely satisfied with the results of surgery. No significant difference was observed between the operated and the contralateral shoulder according to the Rowe and Constant scores. The mean loss of external rotation was 3 degrees . We did not have any cases of anchor loosening, nor did we find signs of shoulder degenerative osteoarthritis on the radiographs. CONCLUSIONS: The knotless anchor seems to be a viable alternative for arthroscopic labrum repair, allowing a good capsular shift. Arthroscopic management of shoulder instability allows us to diagnose and treat associated lesions, thus improving the success rate of this type of surgery. LEVEL OF EVIDENCE: Level IV, case series.

Three-dimensional computed cementless custom femoral stems in young patients: midterm followup.

UNLABELLED: We prospectively evaluated the results of our custom cementless femoral stems to ascertain whether this technology produced reasonable clinical function, complication rates, and loosening rates at midterm. Fifty-seven consecutive patients had surgery in 62 hips for primary osteoarthritis at a mean age of 57 years using a three-dimensional computed custom cementless stem. Patients were reviewed at a mean followup of 94.9 months. At review, the mean Harris hip score was 98.8 points (range, 84-100) compared with 61.1 (range, 28-78) points preoperatively. No patient complained of thigh pain. No migration or subsidence was observed. All stems were considered stable according to the radiographic criteria defined by Engh et al. There were no dislocations, no infections, and no reoperations. Our results are comparable with published results from clinical and radiologic points of view. Two problems remain unsolved: the price of a custom stem is twice as expensive as a standard stem; and we need longer term results before definitely recommending this technology as a reasonable alternative to current arthroplasties in younger patients. The data support the continued exploration of this technology with controlled clinical followup. LEVEL OF EVIDENCE: Therapeutic study, Level II-1 (prospective cohort study). See the Guidelines to Authors for a complete description of levels of evidence.

Long gamma nail in the treatment of subtrochanteric fractures.

INTRODUCTION: The purpose of our study was to retrospectively evaluate the clinical and radiological results of subtrochanteric fractures treated with a long gamma nail (LGN). The LGN has been the implant of choice at our level-1 trauma center since 1992. MATERIALS AND METHODS: Over a period of 7 years, we have treated 90 consecutive patients with subtrochanteric fractures. In order to evaluate the clinical and radiological outcomes, we reviewed the clinical and radiographic charts of these patients followed for a mean time of 2 years (range 13-36 months). RESULTS: We found no intra- or perioperative complications nor early or late infection. Clinical and radiological union was achieved at a mean of 4.3 months in all of the patients (range 3-9 months); in 24 cases (30%) the distal locking bolts were retrieved in order to enhance callus formation and remodeling as a planned secondary surgery. Three patients (3.3%) needed unplanned secondary surgery for problems related to the nailing technique. Two mechanical failures with breakage of the nail were encountered due to proximal varus malalignment, of which one was treated with exchange nailing and grafting and the other one by removal of the broken hardware, blade-plating, and bone grafting. One fracture below a short LGN was treated by exchange nailing. CONCLUSIONS: The minimally invasive technique and simple application of the LGN lead to a low percentage of complications in these difficult fractures after a relatively short learning curve. The biomechanical properties of this implant allow early mobilization and partial weight-bearing even in patients with advanced osteoporosis.

Anterior subluxation after reduction of a posterior traumatic sterno-clavicular dislocation: a case report and a review of the literature.

Sternoclavicular dislocations represent a rare injury. Based on our clinical experience with a patient showing an anterior subluxation after reduction of a posterior traumatic dislocation, we review the literature. The emergent reduction of the dislocation is mandatory, always keeping in mind the potentially devastating neurovascular complications. If the treatment of a residual anterior instability remains controversial, a residual posterior instability should be treated by a surgical procedure. The optimal treatment depends mainly on each surgeon's choice and practice.
