Purpose of the study: Orthopedic treatment is generally proposed for minimally displaced fractures of the scapula. Surgery is indicated in the event of medialization or disorientation of the glenoid cavity. The purpose of this study was to identify rules for management of problematic cases.

Material and methods: This retrospective study included 27 patients, 22 men and five women, mean age 46.7 years (range 22–83 years). The fracture was limited to the scapula in 17 and was part of thoracic syndrome in ten. Injury to the plexus was noted in three patients. Associated lesions were noted in 55% of patients. Orthopedic treatment was proposed for 15 patients (group 1) and surgical treatment for 12 (group 2): neck osteosynthesis (n=4), clavicle fixation (n=5), combined osteosynthesis (n=3).

Results: Mean follow-up was 47.3 months; 21 patients were reviewed (four lost to follow-up, two deaths). Per primam healing was achieved for all fractures. There were no complications related to the surgical procedure in group 2 and no secondary displacement in either group. Mean time to resumed occupational activity was four months (range 0.2–25 months): 2.2 months (1–5 months) in group 1 and 5.5 months (0.2–25 months) in group 2. The age and gender weighted Constant score for the overall series was 96.2% (range 80–100%) with 81% excellent and very good functional outcomes. In group 1, the Constant score was 95.4% (81–100%) with 70% excellent and very good functional outcomes. It was 97% (80–100%) in group 2 with 91% excellent results. At last follow-up, there was only one case of Samilson grade 2 osteoarthritis.

Discussion and conclusion: The functional outcome observed after treatment of scapular fractures is satisfactory. Orthopedic treatment should be reserved for non-displaced fractures. If there is significant medial offset of the glenoid cavity or instability, osteosynthesis of the scapular neck is indicated, possibly with reinforcement by fixation of the clavicle. Isolated osteosynthesis of the clavicle stabilizes the scapular ring but does not reduce the scapular fracture.

Purpose of the study: Resection of the lateral quarter of the clavicle is an effective treatment for painful acromio-clavicular arthropathy. An open procedure can create a disgraceful or painful scar or be associated with secondary instability and muscle weakness. Arthroscopic resection would avoid these complications.

Material and methods: Between 1992 and 2002, 35 patients were treated arthroscopically for isolated painful acromioclavicular arthropathy after failure of medical treatment. Twenty-seven patients (mean age 44 years) were reviewed clinically (Constant score, subjective outcome, stability) and radiographically (quality of resection, coraco-clavicular space, ossification) at more than two years follow-up. Acromioplasty was performed in all cases to improve exposure in 14 or because of an aggressive acromion (n=7). A scarf orthesis was worn to prevent pain. Self-controlled rehabilitation exercises were proposed.

Results: There were no postoperative complications excepting one case of retractile capsulitis in the context of an occupational accident. Excluding this case, mean sick-leave was five weeks (range 3–20). At mean follow-up of seven years, all scars were pain free and minimally visible. There was no problem with frontal or sagittal instability. The Constant score improved 24 points on average compared with the preoperative score with a significant gain for pain (+9 points). Two patients were disappointed: one retained a sequellar capsulitis and one persistent pain after insufficient resection. On average, the resection measured 10 mm (range 6–20 mm). Three patients had an insufficient posterosuperior resection. The coracoclavicular interval remained unchanged in all cases and four patients presented secondary ossification of the resection zone. Two patients were sensitive to acromioclavicular palpation with a positive cross arm test (one had an insufficient resection and the other ossifications at last follow-up).

Discussion and conclusion: Arthroscopic acromio-clavicular resection reduced operative morbidity. The operation does not destabilize the joint. The total joint surface area can be resected to avoid a residual pos-terosuperior impingement which would be a source of persistent pain. The presence of secondary ossifications in the zone of resection has led us to propose NSAID treatment although the prophylactic effect remains to be demonstrated.

Purpose of the study: The revision modular femoral prosthesis (PFM-R) (Centerpulse) uses a cone-shaped straight femoral stem with winglets for press-fit revision fixation in the femoral shaft. The risk of secondary migration further into the shaft is well known. The purpose of this paper was to assess the degree of PFM-R stem migration and to search for predictive factors in order to better ascertain the limits of this type of revision anchorage in the femoral shaft.

Material and methods: Fifty-three files (48 patients) were reviewed retrospectively at minimum none months follow-up. Mean patient age was 56.6 years. Revision was required for loosening (SOFCOT classification): grade 1 (n=5), grade 2 (n=8), grade 3 (n=17), grade 4 (n=10). For 13 hips, the implant to be replaced was not cemented (monobloc stem, infection), or a first-intention PFM-R.

Results: Mean migration was 4.1 mm (0–17 mm), less than 5 mm in 73.5% of cases. There was no correlation between migration and SOFCOT grade. Conversely, there was a significant difference in migration between the grade 1 and grade 3B and between Paprosky grade 1 and 4 (p=0.05). The degree of migration was correlated with the length of the persistent isthma (p< 0.0001), with the morphology of the isthma [conic/inverted conic (p< 0.01), conic/cylindric (p< 0.051)], with the cortical index (p=0.06), the length of the anchor wings (p=0.051), but not with the length of the femorotomy bridge. The length of the wing anchorage was correlated with the length of the persistent isthma (p=0.002) and with the morphology of the isthma [(conic/inverted conic p=0.02), cylindric/inverted conic (p=0.02)], but did not increase significantly with bridging length. There was a trend towards migration in osteoporotic bone (p=0.07).

Discussion and conclusion: Use of a straight stem for anchorage in the femur is associated with secondary migration which depends on the quality of the bone in the anchorage zone and the extent of the press-fit. The persistence of a cone-shaped or cylindrical isthma measuring greater than 4 cm associated with a cortical index greater than 45% and a long wing anchorage can provide excellent primary stability. It would be useless to use long stems since they do not increase the quality of anchorage. The absence of an isthma and the presence of osteoporosis are limitations for this concept.

Purpose: The bifoliated vascularised fibula graft is an attractive alternative for reconstruction of large bone segments. The purpose of this work was to evaluate mid-term results and the usefulness of two surgical techniques: skin island flap monitoring and the arterio-venous loop.

Material and methods: This retrospective analysis included fourteen patients (eleven men and three women) treated between 1992 and 2002. Mean age was 30 years (10–54). Indications were complications of open fractures in nine patients, major bone loss in two, septic nonunion in four, and aseptic nonunion in three. Reconstruction was performed after bone tumour resection in five patients involving immediate reconstruction after failure of an infected massive allograft in four of them. Localisations were: tibia (n=6), femur (n=5), humerus (n=2), and pelvis (n=1). Average bone loss was 10 cm (7–15 cm). Minimal pinning, cerclage or screwing was used to stabilise the flap completed by internal fixation in four patients and external fixation in ten. A monitoring skin island was used for twelve patients (the island was technically impossible in two patients). Vascular anastomoses were performed in seven patients using an arteriovenous loop, performed as a preliminary measure in six.

Results: Mean follow-up was 35 months. One patient died early from tumour progression. Among the seven patients who had an arteriovenous loop, one required revision for a vascular complication. For the seven “classical” bypasses, there were three intraoperative or early complications requiring revision of the anastomoses. Nonunion developed despite early revision in the four patients whose monitoring skin island suffered. Consolidation was achieved without revision in all patients who skin island did not suffer; time to bone healing was eleven months for seven of them.

Conclusion: Bone healing was related to the quality of graft vacularisation. Clinical observation of the monitoring island was the best way to identify vascular complications early and initiate treatment. Use of a preliminary arteriovenous loop decreased the risk of vascular insufficiency inherent with long bypasses and shortened operative time.

Purpose: Maisonneuve fracture is a rare variant of malleolar fractures. Standard surgical care is not well defined. We performed a retrospective analysis of operated patients to propose a system to determine adequate care as a function of the type of lesions observed.

Material and methods: This retrospective analysis involved 20 patients who underwent surgery for Mai-sonneuve fracture between 1989 and 2000. Mean age was 42 years at surgery. Male gender predominated (16 patients). Seven patients (group 1) were treated without a syndesmodesis screw (osteosynthesis of the medial malleolus in six cases and suture of the medial collateral ligament in one). Thirteen patients (group 2) were treated via a first lateral approach and a syndesmodesis screw followed by a complementary medial approach in seven cases (two cases of medial malleolus osteocynthesis and five cases of medial collateral ligament suture). The Duquennoy functional score was determined at last follow-up. Quality of the reduction and presence of degenerative disease were determined on standard x-rays and computed tomographies.

Results: Mean follow-up was four years nine months (range 1–10 years). No case of tibiotalar diastasis was observed at at least one year. Among the five patients reviewed clinically, outcome was excellent in four and fair in one. In group 2 (syndesmodesis), we found two cases of residual diastasis and two cases of tight syndesmosis at at least one year. Among the nine patients reviewed clinically, outcome was excellent in three and fair or poor in six.

Discussion: This retrospective analysis collaborates the few data in the literature on Maisonneuve fractures. Ligament injury has varied greatly (with or without tear of the medial lateral ligament, more or less full thickness rupture of the interosseous membrane). In our experience, it is always difficult to reduce the diastasis via the primary lateral approach. Conversely, the primary medial approach has, after testing, enabled eliminating the syndesmodesis screw, with its recognised deleterious effects, in seven cases.

Conclusion: Due to the diversity of the ligament injuries encountered in patients with Maisonneuve fractures, we have adopted the following surgical strategy. If there is diastasis, after confirmation of any injury to the medical compartment, medial approach to suture the medial collateral ligament or osteosynthesis of the medial malleolus: in the case of diastasis reduction, we advocate a syndesmodesis screw; if diastasis persists, a secondary lateral approach is useful to reduce the medial malleolar rotation and insert a syndesmodesis screw.
